Changes with Apache 2.1.0-dev | |
[Remove entries to the current 2.0 section below, when backported] | |
*) Fix segfault in mod_mem_cache cache_insert() due to cache size | |
becoming negative. PR: 21285, 21287 | |
[Bill Stoddard, Massimo Torquati, Jean-Jacques Clar] | |
*) Add Polish translation of error messages. PR 25101. | |
[Tomasz Kepczynski <tomek jot23.org>] | |
*) mod_proxy with ProxyErrorOverride On in a reverse-proxy configuration attaches | |
a body to the 302 response and a wrong Content-Length header. | |
PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de] | |
*) Bring ErrorHeader concept forward from 1.3, so that response | |
header fields can be set for return even on errors or external | |
redirects. [Ken Coar] | |
*) Fix some piped log problems: bogus "piped log program '(null)' | |
failed" messages during restart and problem with the logger | |
respawning again after Apache is stopped. PR 21648, PR 24805. | |
[Jeff Trawick] | |
*) Add a hook (insert_error_filter) to allow filters to re-insert | |
themselves during processing of error responses. Enable mod_expires | |
to use the new hook to include Expires headers in valid error | |
responses. This addresses an RFC violation. It fixes PRs 19794, | |
24884, and 25123. [Paul J. Reder] | |
*) Fix <Limit> and <LimitExcept> parsing to require a closing '>' | |
in the initial container. PR 25414. | |
[Geoffrey Young <geoff apache.org>] | |
*) Clean up httpd -V output: Instead of displaying the MPM source | |
directory, display the MPM name and some MPM properties. | |
[Geoffrey Young <geoff apache.org>] | |
*) Fixed cache-removal order in mod_mem_cache. | |
[Jean-Jacques Clar, Cliff Woolley] | |
*) Add fatal exception hook for use by debug modules. The hook is only | |
available if the --enable-exception-hook configure parm is used. | |
[Jeff Trawick] | |
*) mod_ssl/mod_status: Re-enable support for output of SSL session | |
cache information in server-status page. [Joe Orton] | |
*) mod_ssl: Remove the shmht session cache, shmcb should be used | |
instead. [Joe Orton] | |
*) mod_ssl: SSL_VERSION_LIBRARY is set to the version string from the | |
SSL library used at run-time, rather than at compile-time. | |
PR: 23956 [Eric Seidel <eseidel apple.com>] | |
*) mod_logio: Account for some bytes handed to the network layer prior to | |
dropped connections. [Jeff Trawick] | |
*) mod_autoindex: new directive IndexStyleSheet | |
[Tyler Riddle <triddle_1999 yahoo.com>, Paul Querna <chip force-elite.com>] | |
*) Fix a long delay with CGI requests and keepalive connections on | |
AIX. [Jeff Trawick] | |
*) Fix uninitialized gprof directory name in prefork MPM. PR 24450. | |
[Chris Knight <Christopher.D.Knight nasa.gov>] | |
*) mod_auth_ldap: Fix some segfaults in the cache logic. PR 18756. | |
[Matthieu Estrade <apache moresecurity.org>] | |
*) mod_autoindex: Add 'XHTML' option in order to allow switching between | |
HTML 3.2 and XHTML 1.0 output. PR 23747. [André Malo] | |
*) Add XHTML Document Type Definitions to httpd.h (minor MMN bump). | |
[André Malo] | |
*) mod_setenvif: Fix the regex optimizer, which under circumstances | |
treated the supplied regex as literal string. PR 24219. | |
[André Malo] | |
*) mod_ssl: Fix segfault on a non-SSL request if the the 'c' log | |
format code is used. PR 22741. [Gary E. Miller <gem rellim.com>] | |
*) Log an error when requests for URIs which fail to map to a valid | |
filesystem name are rejected with 403. [Jeff Trawick] | |
*) Switch to APR 1.0 API. | |
*) Fix mod_include's expression parser to recognize strings correctly | |
even if they start with an escaped token. [André Malo] | |
*) Major overhaul of mod_include's filter parser. The new parser code | |
is expected to be more robust and should catch all of the edge cases | |
that were not handled by the previous one. This includes a binary | |
incompatible change of mod_include's external API. [André Malo] | |
*) mod_rewrite: Allow forced mimetypes [T=...] to get expanded. | |
PR 14223. [André Malo] | |
*) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules | |
could lead to a 400 (Bad Request) response. [André Malo] | |
*) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously | |
the current rewrite state was just used as lookup path, which lead to | |
strange and often useless results. Related to PR 8493. [André Malo] | |
*) Change Listen directive to bind to all addresses when a hostname is | |
not specified. [Justin Erenkrantz] | |
*) Correct failure with Listen directives on machines with IPv6 enabled. | |
[Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz] | |
*) Fix a link failure in mod_ssl when the OpenSSL libraries contain | |
the ENGINE functions but the engine header files are missing. | |
[Cliff Woolley] | |
*) mod_rewrite: RewriteRules in server context using the force | |
type feature [T=...] no longer disable MultiViews. [André Malo] | |
*) mod_rewrite: In external rewrite maps lookup keys containing | |
a newline now cause a lookup failure. PR 14453. | |
[Cedric Gavage <cedric.gavage unixtech.be>, André Malo] | |
*) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot. | |
[André Malo] | |
*) mod_authz_groupfile: Strip trailing spaces of group names. This | |
hopefully saves some hours of searching for typos. PR 12863. | |
[André Malo] | |
*) mod_actions: Propagate the handler name to the action script via | |
the REDIRECT_HANDLER environment variable. [André Malo] | |
*) mod_actions: Introduce the "virtual" modifier to the Action directive, | |
which allows the use of handlers for virtual locations. PR 8431. | |
[André Malo] | |
*) mod_speling: Recognize AcceptPathInfo setting for the particular | |
location. Default is to reject path information. PR 21059. | |
[André Malo] | |
*) mod_ext_filter: Add the ability to filter request bodies. | |
[Philipp Reisner <philipp.reisner linbit.com>] | |
*) mod_cgid: Restart the cgid daemon if it crashes. PR 19849 | |
[Glenn Nielsen <glenn apache.org>] | |
*) Fix some broken log messages in WinNT MPM. | |
[Juan Rivera <Juan.Rivera citrix.com>] | |
*) Add support for IMT minor-type wildcards (e.g., text/*) to | |
ExpiresByType. PR#7991 [Ken Coar] | |
*) prefork MPM: Use the right permissions for the directory created | |
for gprof support. [Jim Carlson <jcarlson jnous.com>] | |
*) Fix a compile failure with recent OpenSSL and picky compilers | |
(e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick] | |
*) OpenSSL headers should be included as "openssl/ssl.h", and not rely on | |
the INCLUDE path to be defined properly. | |
PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>] | |
*) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli] | |
*) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using | |
autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc). | |
[Geoff Thorpe <geoff geoffthorpe.net>] | |
*) change directive name from 'compressionlevel' to 'deflatecompressionlevel' | |
[Ian Holsman, André Malo] | |
*) mod_negotiation: quality values are now parsed independent from | |
the current locale. level values are now really parsed as integers. | |
PR 17564. [André Malo] | |
*) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP | |
to work around problems with certain VPN and Firewall products that | |
have buggy AcceptEx implementations. | |
[Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe] | |
*) Extend mod_negotiation to evaluate the environment variables | |
no-gzip and gzip-only-text/html the same way as mod_deflate does. | |
[André Malo] | |
*) mod_rewrite: Fix some problems reporting errors with mapping | |
programs (RewriteMap prg:/something). [Jeff Trawick] | |

the truncated line. PR 15857. [Justin Erenkrantz] | |
*) Allow restart of httpd to occur even with syntax errors in the config | |
file. PR 16813. [Justin Erenkrantz] | |
*) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679. | |
[Justin Erenkrantz] | |
*) Remove files on 'make distclean' that should be. PR 15592. | |
[Justin Erenkrantz] | |
*) Allow apachectl to perform status with links and elinks as well. | |
[Justin Erenkrantz] | |

matched value. [André Malo] | |
*) mod_log_config change optional hook to return previous handler | |
[Ian Holsman] | |
*) Forward port of mod_actions' ability to handle arbitrary methods | |
with the Script directive. [André Malo] | |
*) Let suexec send a message to stderr, if it failed or its policy | |
was violated. This message appears in the error log and allows | |
for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo] | |
*) Modify buildconf to copy all required files into httpd's tree. | |
[Thom May <thom planetarytramp.net>] | |
*) Allow mod_dav to do weak entity comparison functions. | |
[Justin Erenkrantz] | |
*) Move RFC 1413 ident requests from core to new module mod_ident. | |
[André Malo] | |
*) Add mod_authz_owner - a forward port of "Require file-owner" | |
and "Require file-group", which was already present in version | |
1.3.21. [André Malo] | |
*) Add mod_dav_lock - a generic subset of the DAV locking implementation. | |
[Justin Erenkrantz] | |
*) Replace some of the mutex locking in the worker MPM with | |
atomic operations for higher concurrency. [Brian Pane] | |
*) Allow 'make depend' to work with non-GCC compilers. | |
[Justin Erenkrantz] | |
*) If an httpd.conf has commented out AddModule directives, | |
apxs -i -a will add an un-commented AddModule directive for | |
the new module, which breaks the config. | |
PR: 11212 [Joe Orton] | |
*) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz] | |
*) Move the check of the Expect request header field after the hook | |
for ap_post_read_request, since that is the only opportunity for | |
modules to handle Expect extensions. [Justin Erenkrantz] | |
*) Rewrite of aaa modules to an authn/authz model. | |
[Dirk-Willem van Gulik, Justin Erenkrantz] | |
[Apache 2.1.0-dev includes those bug fixes and changes with the | |
Apache 2.0.xx tree as documented, and except as noted, below.] | |
Changes with Apache 2.0.49 | |
*) Add AP_MPMQ_MPM_STATE function code for ap_mpm_query. (Not yet | |
supported for BeOS, OS/2, or Win32 MPMs.) [Jeff Trawick, | |
Brad Nicholes] | |

report. [Joe Orton] | |
*) Fix htdbm to generate comment fields in DBM files correctly. | |

*) mod_status: Report total CPU time accurately when using a threaded | |
MPM. PR 23795. [Jeff Trawick] | |
*) Fix memory leak in handling of request bodies during reverse | |
proxy operations. PR 24991. [Larry Toppi <larry.toppi citrix.com>] | |
*) Win32 MPM: Implement MaxMemFree to enable setting an upper | |
limit on the amount of storage used by the bucket brigades | |
in each server thread. [Bill Stoddard] | |
*) Modified the cache code to be header-location agnostic. Also | |
fixed a number of other cache code bugs related to PR 15852. | |
Includes a patch submitted by Sushma Rai <rsushma novell.com>. | |
This fixes mod_mem_cache but not mod_disk_cache yet so I'm not | |
closing the PR since that is what they are using. [Paul J. Reder] | |
*) complain via error_log when mod_include's INCLUDES filter is | |
enabled, but the relevant Options flag allowing the filter to run | |
for the specific resource wasn't set, so that the filter won't | |
silently get skipped. next remove itself, so the warning will be | |
logged only once [Stas Bekman, Jeff Trawick, Bill Rowe] | |
*) mod_info: HTML escape configuration information so it displays | |
correctly. PR 24232. [Thom May] | |
*) Restore the ability to add a description for directories that | |
don't contain an index file. (Broken in 2.0.48) [André Malo] | |
*) Fix a problem with the display of empty variables ("SetEnv foo") in | |
mod_include. PR 24734 [Markus Julen <mj zermatt.net>] | |
*) mod_log_config: Log the minutes component of the timezone correctly. | |
PR 23642. [Hong-Gunn Chew <hgbug gunnet.org>] | |
*) mod_proxy: Fix cases where an invalid status-line could be sent | |
to the client. PR 23998. [Joe Orton] | |
*) mod_ssl: Fix segfaults at startup if other modules which use OpenSSL | |
are also loaded. [Joe Orton] | |
*) mod_ssl: Use human-readable OpenSSL error strings in logs; use | |
thread-safe interface for retrieving error strings. [Joe Orton] | |
*) mod_expires: Initialize ExpiresDefault to NULL instead of "" to | |
avoid reporting an Internal Server error if it is used without | |
having been set in the httpd.conf file. PR: 23748, 24459 | |

set, for example, when processing some error conditions. | |
PR 23836. [Brian Akins <bakins web.turner.com>, André Malo] | |
*) fix the config parser to support <Foo>..</Foo> containers (no | |

this change mod_perl 2.0's <Perl> sections are broken. | |
["Philippe M. Chiasson" <gozer cpan.org>] | |

*) Install config.nice into the build/ directory to make | |
minor version upgrades easier. [Joshua Slive] | |
*) Fix mod_deflate so that it does not call deflate() without checking | |
first whether it has something to deflate. (Currently this causes | |
deflate to generate a fatal error according to the zlib spec.) | |

As with 1.3, for proxy requests any such field is from the origin | |
server; otherwise it will have our server info as controlled by | |
the ServerTokens directive. [Jeff Trawick] | |
Changes with Apache 2.0.47 | |
*) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences | |
of per-directory renegotiations and the SSLCipherSuite directive | |
being used to upgrade from a weak ciphersuite to a strong one | |
could result in the weak ciphersuite being used in place of the | |
strong one. [Ben Laurie] | |
*) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing | |
temporary denial of service when accept() on a rarely accessed port | |
returns certain errors. Reported by Saheed Akhtar | |

*) Add support for "streamy" PROPFIND responses. | |
[Ben Collins-Sussman <sussman collab.net>] | |

various operational problems in a threaded MPM, since on the | |
second attempt to close the socket, the same descriptor was | |
often already in use by another thread for another purpose. | |
[Jeff Trawick] | |
*) mod_negotiation: Introduce "prefer-language" environment variable, | |
which allows to influence the negotiation process on request basis | |
to prefer a certain language. [André Malo] | |

dynamically-generated documents. [Ken Coar, Bill Stoddard] | |
Changes with Apache 2.0.46 | |

*) Performance improvement for keepalive requests: when setting | |
aside a small file for potential concatenation with the next | |

than copying the file into the heap. [Brian Pane] | |
*) Modified version check on openssl so that it finds the executable | |
first and then performs a check of the version, only warning the | |

This change also allows the code to work for non-openssl libraries | |
selected via the --with-ssl=dir option, which can override the | |
automated library check in any case. [Roy Fielding] | |

configuration. Without upgrading, a single .conf change will close | |
the vulnerability. Add the following directive in the global server | |
httpd.conf context before any other Alias or Redirect directives; | |
RedirectMatch 400 "\\\.\." | |

multiple documents or no documents could be served based on the mime | |
negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>. | |
[William Rowe] | |
*) SECURITY [CAN-2002-0654] (cve.mitre.org): | |
Close a path-revealing exposure in cgi/cgid when we | |

[William Rowe] | |
*) Fix proxy so that it is possible to access ftp: URLs via a proxy | |
chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>] | |
*) mod-deflate now checks to make sure that 'gzip-only-text/html' is | |
set to 1, so we can exclude things from the general case with | |
browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>] | |
*) Accept multiple leading /'s for requests within the DocumentRoot. | |
PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>] | |
*) Solved the reports of .pdf byterange failures on Win32 alone. | |
APR's sendfile for the win32 platform collapses header and trailer | |
buffers into a single buffer. However, we destroyed the pointers | |
to the header buffer if a trailer buffer was present. PR 10781 | |
[William Rowe] | |

*) When deciding on the default address family for listening sockets, | |
make sure we can actually bind to an AF_INET6 socket before | |
deciding that we should default to AF_INET6. This fixes a startup | |
problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick] | |
*) Replace usage of atol() to parse strings when we might want a | |
larger-than-long value with apr_atoll(), which returns long long. | |
This allows HTTPD to deal with larger files correctly. | |
[Shantonu Sen <ssen apple.com>] | |
*) mod_ext_filter: Ignore any content-type parameters when checking if | |
the response should be filtered. Previously, "intype=text/html" | |
wouldn't match something like "text/html;charset=8859_1". | |
[Jeff Trawick] | |
*) mod_ext_filter: Set up environment variables for external programs. | |
[Craig Sebenik <craig netapp.com>] | |
*) Modified the HTTP_IN filter to immediately append the EOS (end of | |
stream) bucket for C-L POST bodies, saving a roundtrip and allowing | |
the caller to determine that no content remains without prefetching | |
additional POST body. [William Rowe] | |

*) APR-Util Renames pending have been completed [Thom May] | |
*) Performance improvements for the code that reads request | |
headers (ap_rgetline_core() and related functions) [Brian Pane] | |
*) Add a new directive: MaxMemFree. MaxMemFree makes it possible | |
to configure the maximum amount of memory the allocators will | |
hold on to for reuse. Anything over the MaxMemFree threshold | |
will be free()d. This directive is useful when uncommon large | |
peaks occur in memory usage. It should _not_ be used to mask | |
defective modules' memory use. [Sander Striker] | |
*) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI | |
scripts would not result in a truncated response. | |
[Ryan Bloom, Justin Erenkrantz, Cliff Woolley] | |
*) Add a filter_init parameter to the filter registration functions | |
so that a filter can execute arbitrary code before the handlers | |
are invoked. This resolves a problem where mod_include requests | |
would incorrectly return a 304. [Justin Erenkrantz] | |
*) Fix a long-standing bug in 2.0, CGI scripts were being called | |
with relative paths instead of absolute paths. Apache 1.3 used | |
absolute paths for everything except for SuExec, this brings back | |
that standard. [Ryan Bloom] | |
*) Fix infinite loop due to two HTTP_IN filters being present for | |
internally redirected requests. PR 10146. [Justin Erenkrantz] | |
*) Switch conn_rec->keepalive to an enumeration rather than a bitfield. | |
[Justin Erenkrantz] | |
*) Fix mod_ext_filter to look in the main server for filter definitions | |
when running in a vhost if the filter definition is not found in | |
the vhost. PR 10147 [Jeff Trawick] | |
*) Support WinNT CGI invocation through ScriptInterpreterSource | |
'registry' for script interpreter paths and names with non-ascii | |
characters in the executable filepath. [William Rowe] | |
*) Support the -w flag on to keep the Win32 console open on error. | |
[William Rowe] | |
*) Normalize the hostname value in the request_rec to all-lowercase | |
[Perry Harrington <pedward webcom.com>] | |
*) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include | |
extended characters (non US-ASCII) in non-utf8 format. This brings | |
Win32 back into CGI/1.1 compliance, and leaves charset decoding up | |
to the cgi application itself. [William Rowe] | |
*) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache | |
modules to bring them up to the current apr/apr-util APIs. | |
[William Rowe] | |
*) Fix segfault in mod_mem_cache most frequently observed when | |
serving the same file to multiple clients on an MP machine. | |
[Bill Stoddard] | |

PR 10074 [Jeff Trawick] | |
*) Fix a silly htpasswd.c logic error that incorrectly reported that | |
both -c and -n had been used. PR 9989 [Cliff Woolley] | |
*) Fixed a mod_include error case in which no HTTP response was sent | |
to the client if an shtml document contained an unterminated SSI | |
directive [Brian Pane] | |
*) Improve ap_get_client_block implementation by using APR-util brigade | |
helper functions and relying on current filter assumptions. | |
[Justin Erenkrantz] | |
Changes with Apache 2.0.39 | |
*) Fixed a build problem in htpasswd.c on Win32. | |
[Guenter Knauf <eflash gmx.net>, Cliff Woolley] | |
Changes with Apache 2.0.38 | |
*) Rewrite htpasswd to use APR. The removes the annoying warning about | |
tmpnam being unsafe. [Ryan Bloom] | |
*) We must set the MIME-type for .shtml files to text/html if we want them | |
to be parsed for SSI tags. Add the config for that to the default | |
config file so that it is easier to enable .shtml parsing. | |
[Dave Dyer <ddyer real-me.net>] | |
*) Fixed a problem with 'make install' on ReliantUnix. | |
[Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>] | |
*) Make the default_handler catch all requests that aren't served by | |
another handler. This also gets us to return a 404 if a directory | |
is requested, there is no DirectoryIndex, and mod_autoindex isn't | |
loaded. [Justin Erenkrantz] | |
*) Fixed the handling of nested if-statements in shtml files. | |
PR 9866 [Brian Pane] | |
*) Allow 'make install DESTDIR=/path'. This allows packagers to install | |
into a directory different from the one that was configured. This | |
also mirrors the root= feature from 1.3. We cannot use prefix=, | |
because both APR and APR-util resolve their installation paths at | |
configuration time. This means that there is no variable prefix | |
to replace. [Andreas Hasenack <andreas netbank.com.br>] | |
*) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT. | |
These levels of AIX don't have a thundering herd problem with | |
accept(). [Jeff Trawick] | |
*) prefork MPM: Ignore mutex errors during graceful restart. For | |
certain types of mutexes (particularly SysV semaphores), we | |
should expect to occasionally fail to obtain or release the | |
mutex during restart processing. [Jeff Trawick] | |
*) Fix install-bindist.sh so that it finds any perl instead of just | |
early perl 5.x versions. This is consistent with a build/install | |
from source, and it allows the perl scripts installed by a bindist | |
to work on systems with perl 5.6. [Jeff Trawick] | |
*) Fix apxs so that the makefile created by "apxs -g" works on AIX and | |
Tru64 (and probably some other platforms). [Jeff Trawick] | |
*) Allow CGI scripts to return their Content-Length. This also fixes a | |
hang on HEAD requests seen on certain platforms (such as FreeBSD). | |
[Justin Erenkrantz] | |
*) Added log rotation based on file size to the RotateLog support | |
utility. [Brad Nicholes] | |
*) Fix some casting in mod_rewrite which broke random maps. | |
PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick] | |
Changes with Apache 2.0.37 | |
*) allow POST method over SSL when per-directory client cert | |
authentication is used with 'SSLOptions +OptRenegotiate' enabled | |

match how 1.3 does it. [Jim Jagielski] | |
*) Implement a fixed size memory cache using a priority queue | |
[Ian Holsman] | |
*) Fix apxs to allow "apxs -q installbuilddir" and to allow | |
querying certain other variables from config_vars.mk. PR 9316 | |
[Jeff Trawick] | |
*) Added the "detached" attribute to the cgi_exec_info_t internals | |
so that Win32 and Netware won't create a new window or console | |
for each CGI invoked. PR 8387 | |
[Brad Nicholes, William Rowe] | |
*) Consolidated the command line parameters and attributes that are | |
manipulated by the optional function ap_cgi_build_command() in | |
mod_cgi into a single structure. | |
[Brad Nicholes] | |
*) Get rid of uninitialized value errors with "apxs -q" on certain | |

*) Fix apxs to allow it to work when the build directory is somewhere | |
besides server-root/build. PR 8453 | |
[Jeff Trawick and a host of others] | |
*) Allow ap_discard_request_body to be called multiple times in the | |
same request. Essentially, ap_http_filter keeps track of whether | |
it has sent an EOS bucket up the stack, if so, it will only ever | |
send an EOS bucket for this request. | |
[Ryan Bloom, Justin Erenkrantz, Greg Stein] | |
*) Remove all special mod_ssl URIs. This also fixes the bug where | |
redirecting (.*) will allow an SSL protected page to be viewed | |
without SSL. [Ryan Bloom] | |
*) Fix the binary build install script so that the build logic | |
created by "apxs -g" will work when the user has a binary | |
build. [Jeff Trawick] | |
*) Allow instdso.sh to work with full paths to the shared module. | |
[Justin Erenkrantz] | |
*) NetWare: Enabled CGI functionality and added mod_cgi as a built | |
in module for NetWare [Brad Nicholes] | |
*) Changed cgi and piped log behavior to accept 65536 characters | |
on Win32 (matching Linux) before deadlocking between outputing | |
client stdin, slurping the output from stdout and then the stderr | |
stream. PR 8179 [William Rowe] | |
*) Fixed Win32 wintty.exe support to assure the window title is valid. | |
Elimiates possible gpfault or garbage title without the -t option. | |
[William Rowe] | |
*) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use | |
brigades and input filters. [Justin Erenkrantz] | |
*) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request | |
body. [Justin Erenkrantz] | |
*) NetWare: Piping log entries through RotateLogs using the | |
CustomLogs directive is finally supported now that we have | |
the pipes and spawning functionality working. | |

in some server restart scenarios. [Jeff Trawick] | |
*) Added exp_foo and rel_foo variables to config_vars.mk for | |
all Apache and Autoconf path variables (like --sysconfdir, | |
--sbindir, etc). exp_foo is the "expanded" version, which means | |
that all internal variable references have been interpolated. | |
rel_foo is the same as $exp_foo, only relative to $prefix if they | |
share a common path. [Aaron Bannert] | |
*) Fix some restart/terminate problems in the worker MPM. Don't | |

not present, first an anonymous segment is created, and if that | |
fails, a name-based segment is created from a file of the name | |
DEFAULT_SCOREBOARD. This gives third-party applications the | |
ability to access our scoreboard. [Aaron Bannert] | |
*) Allow mod_deflate to work with non-GET requests and properly send | |
Content-Lengths. [Sander Striker <striker apache.org>] | |
*) Fix ap_directory_merge() to correctly merge configs when there is | |
no <Directory /> block. [Justin Erenkrantz, William Rowe] | |
*) Remove spurious debug messsages that are normal under HTTP | |
keep-alive logic. [Jeff Trawick, Justin Erenkrantz] | |
*) Fix a bug in mod_cgid that would prevent proper shutdown death | |
of the cgid process. [Aaron Bannert] | |
*) Add signal handling back in to the worker MPM for the one_process | |
(-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert] | |
*) Performance: Reuse per-connection transaction pools in the | |
worker MPM, rather than destroying and recreating them. [Brian Pane] | |
*) Remove all signals from the worker MPM's child process. Instead, | |
the parent uses the Pipe of Death for all communication with the | |
child processes. [Ryan Bloom] | |
Changes with Apache 2.0.32 | |
*) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the | |
default if the directive is not specified. This mirrors older | |
behavior without changes to the httpd.conf. [William Rowe] | |
*) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing | |
the service, mpm and logging code, and bugs in apr_file_open_stderr | |
and apr_file_dup2 functions. Win2K/XP services have no handles | |
associated for stdin/out/err, which caused unpredictable behavior | |
in the prior release. [William Rowe, Bill Stoddard] | |
*) Win32: simplify the Application Event Log messages, since there isn't | |
likely to be 'more information in the error log' before an error log | |
has been opened. [William Rowe] | |
*) Win32: substantial cleanup to the mpm_winnt code for legibility and | |
to follow the program flow of other MPMs. [Ryan Bloom, William Rowe] | |
*) Win32: apache -k shutdown now behaves like apache -k stop. | |
[Bill Stoddard] | |
*) Fix prefork to not kill the parent if a child hits a resource shortage | |
on accept(). [Greg Ames] | |
*) Fix seg faults that occur when what should be the httpd request line | |
starts with \r\n followed by garbage. [Greg Ames] | |
*) Allow statically linked support binaries with the new | |
--enable-static-support flag, and enable this behavior in | |
the binbuild script. Also add a new --enable-static-htdbm | |
flag. [Aaron Bannert] | |
*) Allow mod_autoindex to serve symlinks if permitted and attempt to | |
do only one stat() call when generating the directory listings. | |
[Justin Erenkrantz] | |
*) Fix resolve_symlink to save the original symlink name if known. | |
[Justin Erenkrantz] | |
*) Be a bit more sane with regard to CanonicalNames. If the user has | |
specified they want to use the CanonicalName, but they have not | |
configured a port with the ServerName, then use the same port that | |
the original request used. [Ryan Bloom and Ken Coar] | |
*) In core_input_filter, check for an empty brigade after | |
APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a | |
client says it will post some data but we get FIN before any | |
data arrives. [Jeff Trawick] | |
*) Not being able to bind to the socket is a fatal error. We should | |
print an error to the console, and return a non-zero status code. | |
With these changes, all of the Unix MPMs do that correctly. | |
[Ryan Bloom] | |
*) suexec: Allow HTTPS and SSL_* environment variables to be passed | |
through to CGI scripts. PR 9163 | |
[Brian Reid <breid customlogic.com>, | |
Zvi Har'El <rl math.technion.ac.il>] | |
*) binbuild.sh: Make sure that we use the expat from our source | |
tree so that there aren't any surprises on the target machine. | |
[Jeff Trawick] | |
*) mod_cgid: Add retry logic for when the daemon can't fork fast | |
enough to keep up with new requests. Start using | |
HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR | |
when we can't talk to the daemon. [Jeff Trawick] | |
*) apxs: LTFLAGS envvar can override default libtool options. Try | |
"LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under | |
the covers. [Jeff Trawick] | |
*) The Location: response header field, used for external | |
redirect, *must* be an absoluteURI. The Redirect directive | |
tested for that, but RedirectMatch didn't -- it would allow | |
almost anything through. Now it will try to turn an abs_path | |
into an absoluteURI, but it will correctly varf like Redirect | |
if the final redirection target isn't an absoluteURI. [Ken Coar] | |
Changes with Apache 2.0.31 | |
*) Create the scoreboard (in the parent) in a global pool context, | |
so it survives graceful restarts. This fixes a SEGV during | |
graceful restarts. [Aaron Bannert] | |
*) Add a timeout option to the proxy code 'ProxyTimeout' | |
[Ian Holsman] | |
*) FTP directory listings are now always retrieved in ASCII mode. | |
The FTP proxy properly escapes URI's and HTML in the generated | |
listing, and escapes the path components when talking to the FTP | |
server. It is now possible to browse the root directory by using | |
a url like: ftp://user@host/%2f/ (ported from apache_1.3.24) | |
Also, the last path component may contain wildcard characters | |
'*' and '?', and if they do, a directory listing is created instead | |
of a file retrieval. Example: ftp://user@host/httpd/server/*.c | |
[Martin Kraemer] | |
*) Added single-listener unserialized accept support to the | |
worker MPM [Brian Pane] | |
*) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes | |
the incoming host header through to the proxied server | |
[Geoff <g.russell ieee.org>] | |
*) New Directive Option for ProxyPass. It now can block a location | |
from being proxied [Jukka Pihl <jukka.pihl entirem.com>] | |
*) Don't let the default handler try to serve a raw directory. At | |
best you get gibberish. Much worse things can happen depending | |
on the OS. [Jeff Trawick] | |
*) Change the pre_config hook to return a value. Modules can now emit | |
an error message and then cause the server to quit gracefully during | |
startup. This required a bump to the MMN. [Aaron Bannert] | |
*) Fix some unix socket descriptor leaks in the handler side of | |
mod_cgid (the part that runs in the server process). Whack a | |
silly "close(-1)" in the handler too. [Jeff Trawick] | |
*) Change the pre_mpm hook to return a value, so that scoreboard | |
init errors percolate up to code that knows how to exit | |
cleanly. This required a bump to the MMN. [Jeff Trawick] | |
*) Add the socket back to the conn_rec and remove the create_connection | |
hook. The create_connection hook had a design flaw that did not | |
allow creating connections based on vhost info. [Bill Stoddard] | |
*) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results. | |
Resolves the common case of using negotation to resolve the request | |
/script/foo for /script.cgi/foo. [William Rowe] | |
*) Added new functions ap_add_(input|output)_filter_handle to | |
allow modules to bypass the usual filter name lookup when | |
adding hard-coded filters to a request [Brian Pane] | |
*) caching should now work on subrequests (still very experimental) | |
[Ian Holsman] | |
*) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe] | |
*) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*. | |
[Justin Erenkrantz] | |
*) Refactor ap_rgetline so that it does not use an internal brigade. | |
Change ap_rgetline's prototype to return errors. [Justin Erenkrantz] | |
*) Remove mod_auth_db. [Justin Erenkrantz] | |
*) Do not install unnecessary pcre headers like config.h and internal.h. | |
[Joe Orton <joe manyfish.co.uk>] | |
*) Change in quick_hanlder behavior for subrequests. it now passes DONE | |
(as it does for a normal request). quick_handled sub-requests now work | |
in mod-include [Ian Holsman] | |
*) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of | |
'CONTENT' one, as it needs to run AFTER all content headers | |
*) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread. | |
[Lars Eilebrecht] | |
*) Split out blocking from the mode in the input filters. | |
[Justin Erenkrantz] | |
*) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick] | |
*) Cause Win32 to capture all child-worker process errors in | |
Apache to the main server error log, until the child can | |
open its own error logs. [William Rowe] | |
*) HPUX 11.*: Do not kill the child process when accept() | |
returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch) | |
[Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard] | |
*) Fix a problem in the parsing of the <Proxy foo> directive. | |
[Jeff Trawick] | |
*) rewrite of mod_ssl input filter for better performance and less | |
memory usage [Doug MacEachern] | |
*) allow quick_handler to be run on subrequests. [Ian Holsman] | |
*) mod_dav now asks its provider to place content directly into the | |
filter stack when handling a GET request. The mod_dav/provider | |
API has changed, so providers need to be updated. [Greg Stein] | |
*) Clear the output socket descriptor in unixd_accept() to make sure | |
we don't supply a bogus socket to the caller if the accept fails. | |
This caused problems with the worker MPM, which tried to process | |
the returned socket if it was non-NULL. [Brian Pane] | |
*) Move a check for an empty brigade to the start of core input filter | |
to avoid segfaults. [Justin Erenkrantz, Jeff Trawick] | |
*) Add FileETag directive to allow configurable control of what | |
data are used to form ETag values for file-based URIs. MMN | |
bumped to 20020111 because of fields added to the end of | |
the core_dir_config structure. [Ken Coar] | |
*) Fix a segfault in mod_rewrite's logging code caused by passing the | |
wrong config to ap_get_remote_host(). [Jeff Trawick] | |
*) Allow mod_cgid to work from a binary distribution install by | |
using 755 for the permissions on the log directory instead of | |
750. [Jeff Trawick] | |
*) Fixed a segfault that happened during graceful shutdown (or when | |
the httpd ran out of file descriptors) with the worker MPM [Brian Pane] | |
*) Split all Win32 modules [excluding the core components mod_core, | |
mod_so, mod_win32 and the winnt mpm] into individual loadable | |
modules, so the administrator may individually disable the former | |
compiled-in modules by simply commenting out their LoadModule | |
directives. [William Rowe] | |
*) Saved Win32 module authors and porters many future headaches, by | |
duplicating the appropriate .h files such as os.h into the include | |
directory, including in the build tree. [William Rowe] | |
*) mod_ssl adjustments to help with using toolkits other than OpenSSL: | |
Use SSL functions/macros instead of directly dereferencing SSL | |
structures wherever possible. | |
Add type-casts for the cases where functions return a generic pointer. | |
Add $SSL/include to configure search path. | |
[Madhusudan Mathihalli <madhusudan_mathihalli hp.com>] | |
*) Moved several pointers out of the shared Scoreboard so it is | |
more portable, and will present the vhost name across server | |
generation restarts. [William Rowe] | |
*) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec: | |
[Doug MacEachern] | |
Changes with Apache 2.0.30 | |
*) Fix the main bug for FreeBSD and threaded MPM's. There are | |
still issues (see STATUS) but at least the server will now | |
run without crashing the machine. | |
[David Reid, Aaron Bannert, Justin Erenkrantz] | |
*) Fix a typo in mod_deflate's m4 config section. | |
[albert chin <china thewrittenword.com>] | |
*) Fix a couple of mod_proxy problems forwarding HTTP connections | |
and handling CONNECT: | |
(1) PR #9190 Proxy failed to connect to IPv6 hosts. | |
(2) Proxy failed to connect when the first IP address returned by | |
the resolver was unreachable but a secondary IP address was. | |
[Jeff Trawick] | |
*) Fix the module identifer as shown in the docs for various core | |
modules (e.g., the identifer for mod_log_config was previously | |
listed as config_log_module). PR #9338 | |
[James Watson <ap2bug sowega.org>] | |
*) Fix LimitRequestBody directive by placing it in the HTTP | |
filter. [Justin Erenkrantz] | |
*) Fix mod_proxy seg fault when the proxied server returns | |
an HTTP/0.9 response or a bogus status line. | |
[Adam Sussman] | |
*) Prevent mod_proxy from truncating one character off the | |
end of the status line returned from the proxied server. | |
[Adam Sussman, Bill Stoddard] | |
*) Eliminate loop in ap_proxy_string_read(). | |
[Adam Sussman, Bill Stoddard] | |
*) Provide $0..$9 results from mod_include regex parsing. | |
[William Rowe] | |
*) Allow mod-include to look for alternate start & end tags [Ian Holsman] | |
*) Introduced the ForceLanguagePriority directive, to prevent | |
returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases, | |
when using Multiviews. [William Rowe] | |
*) Fix a problem which prevented mod_cgid and suexec from working | |
together reliably [Greg Ames] | |
*) Remove the call to exit() from within mod_auth_digest's post_config | |
phase. [Aaron Bannert] | |
*) Fix a problem in mod_auth_digest that could potentially cause | |
problems with initialized static data on a system that uses DSOs. | |
[Aaron Bannert] | |
*) Fix a segfault in the worker MPM that could happen during | |
child process exits. [Brian Pane, Aaron Bannert] | |
*) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman] | |
*) Fix matching of vhosts by ip address so we find IPv4 | |
vhost address when target address is v4-mapped form of | |
that address. [Jeff Trawick] | |
*) More performance tweaks to the BNDM string-search algorithm | |
used to find "<!--#" tokens in mod_include [Brian Pane] | |
*) Miscellaneous small performance fixes: optimized away various | |
string copy operations and removed large temp buffers from | |
the stack [Brian Pane] | |
*) Fixed startup segfault that occurred when a VirtualHost | |
directive had a port but no address [Brian Pane] | |
*) Allow htdbm to work with multiple DBM types [Ian Holsman] | |
*) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL | |
if oslevel < WINNT. This should fix several problems reported | |
Against 2.0.28 on Windows 98 [Bill Stoddard] | |
*) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS | |
to fail. [Bill Stoddard] | |
*) Change core code to allow an MPM to set hard thread/server | |
limits at startup. prefork, worker, and perchild MPMs now have | |
directives to set these limits. [Jeff Trawick] | |
*) Win32: The async AcceptEx() event should be autoreset upon | |
successful completion of a wait (WaitForSingleObject). This | |
eliminates a number of spurious | |
setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages. | |
[Bill Stoddard] | |
*) Move any load library path environment variables out of | |
apachectl and into a separate environment variable file which | |
can be more easily tailored by the admin. The environment | |
variable file as built by Apache may have additional system- | |
specific settings. For example, on OS/390 we tailor the heap | |
settings to allow lots of threads. [Jeff Trawick] | |
*) Use the new APR pool code to reduce pool-related lock | |
contention in the worker MPM. [Sander Striker] | |
*) The POD no longer assumes the child is listening on 127.0.0.1 | |
and now pulls the first hostname in the list of listeners to | |
perform the dummy connect on. This fixes a bug when the user | |
had configured the Listen directive for an IP other than | |
127.0.0.1. This would result in undead children and error | |
messages such as "Connection refused: connect to listener". | |
[Aaron Bannert] | |
*) The worker MPM now respects the LockFile setting, needed to | |
avoid locking problems with NFS. [Jeff Trawick] | |
*) Fix segfault when worker MPM receives SIGHUP. | |
[Ian Holsman, Aaron Bannert, Justin Erenkrantz] | |
*) Fix bug that could potentially prevent the perchild MPM from | |
working with more than one vhost/uid. [Aaron Bannert] | |
*) Change make install and apxs -i processing of DSO modules to | |
perform special handling on platforms where libtool doesn't install | |
mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX | |
which prevented standard LoadModule statements from working. | |
[Jeff Trawick] | |
*) Whenever mod_so is enabled (not just when there are DSOs for | |
our modules), do whatever special magic is required for compiling/ | |
loading third-party modules. This allows third-party DSOs to | |
be used on an AIX build when there were no built-in modules | |
built as DSOs. (This should help on OS/390 and BeOS as well.) | |
[Jeff Trawick] | |
*) Allow apxs to be used to build DSOs on AIX without requiring the | |
user to hard-code the list of import files. (This should help | |
on OS/390 and BeOS as well.) [Jeff Trawick] | |
*) Resolved segfault in mod_isapi when configuring with ISAPICacheFile. | |
PR 8563, 8919 [William Rowe] | |
*) Get binary builds working when libapr and libaprutil are built | |
shared [Greg Ames] | |
*) Get shared builds of libapr and libaprutil, as well as Apache DSOs, | |
working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>, | |
Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick] | |
*) Fix the handling of SSI directives in which the ">" of the | |
terminating "-->" is the last byte in a file [Brian Pane] | |
*) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)" | |
message that we had back in apache-1.3 and still have scattered | |
throughout our docs. [Aaron Bannert] | |
*) Prevent the Win32 port from continuing after encountering an | |
error in the command line args to apache. [William Rowe] | |
*) On a error in the proxy, make it write a line to the error log | |
[Ian Holsman] | |
*) Various mod_ssl performance improvements [Doug MacEachern] | |
Changes with Apache 2.0.29 | |
*) Add buffering in core_output_filter to ensure that long | |
lists of small buckets don't cause small packet writes. | |
[Brian Pane, Ryan Bloom] | |
*) Fix the installation target to make sure that the manual is | |
installed in the correct location. | |
[Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and | |
Gomez Henri <hgomez slib.fr>] | |
*) Fix the cmd command for mod_include. When we are processing | |
a cmd command, we do not want to use the r->filename to set | |
the command name. The command comes from the SSI tag. To do this, | |
I added a variable to the function that builds the command line | |
in mod_cgi. This allows the include_cmd function to specify | |
the command line itself. [Ryan Bloom] | |
*) Change open_logs hook to return a value, allowing you | |
to flag a error while opening logs | |
[Ian Holsman, Doug MacEachern] | |
*) Change post_config hook to return a value, allowing you | |
to flag a error post config | |
[Ian Holsman, Jeff Trawick] | |
*) Allow SUEXEC_BIN (the path to the suexec binary that is | |
hard-coded into the server) to be specified to the configure | |
script by the --with-suexec-bin parameter. [Aaron Bannert] | |
*) Fix segv in worker MPM following accept on pipe-of-death | |
[Brian Pane] | |
*) Add mod_deflate to experimental. | |
[Ian Holsman, Justin Erenkrantz] | |
*) Bail out at configure time if an invalid MPM was specified. | |
[jean-frederic clere <jfrederic.clere fujitsu-siemens.com>] | |
*) Prevent segv in ap_note_basic_auth_failure() when no AuthName is | |
configured [John Sterling <sterling covalent.net>] | |
*) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>] | |
*) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick] | |
*) Optimization for the BNDM string-search function in | |
mod_include. [Brian Pane] | |
*) Fixed the behavior of the XBitHack directive. | |
[Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804 | |
*) The threaded MPM for Unix has been removed. Use the worker | |
MPM instead. [various] | |
*) APR-ize the resolver logic in mod_unique_id. This fixes a bug | |
in logging the error from a failed DNS lookup. [Jeff Trawick] | |
*) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123. | |
[Cliff Woolley] | |
*) Get mod_cgid killed when a MPM exits due to a fatal error. | |
[Jeff Trawick] | |
*) Fix a file descriptor leak in mod_include. When we include a | |
file, we use a sub-request, but we didn't destroy the sub-request | |
immediately, instead we waited until the original request was | |
done. This patch closes the sub-request as soon as the data is | |
done being generated. [Brian Pane <bpane pacbell.net>] | |
*) Allow modules that add sockets to the ap_listeners list to | |
define the function that should be used to accept on that | |
socket. Each MPM can define their own function to use for | |
the accept function with the MPM_ACCEPT_FUNC macro. This | |
also abstracts out all of the Unix accept error handling | |
logic, which has become out of synch across Unix MPMs. | |
[Ryan Bloom] | |
*) Fix a bug which would cause the response headers to be omitted | |
when sending a negotiated ErrorDocument because the required | |
filters were attached to the wrong request_rec. | |
[John Sterling <sterling covalent.net>] | |
*) Remove commas from the end of the macros that define | |
directives that are used by MPMs. Prior to this patch, | |
you would use these macros without commas, which was unlike | |
the macros for any other directives. Now, the caller provides | |
the comma rather than the macro providing it. This makes | |
the macros look more like the rest of the directives. | |
[Ryan Bloom and Cliff Woolley] | |
*) Add 'redirect-carefully' environment option to disable sending | |
redirects under special circumstances. This is helpful for | |
Microsoft's WebFolders when accessing a directory resource via | |
DAV methods. [Justin Erenkrantz] | |
*) Begin to abstract out the underlying transport layer. | |
The first step is to remove the socket from the conn_rec, | |
the server now lives in a context that is passed to the | |
core's input and output filters. This forces us to be very | |
careful when adding calls that use the socket directly, | |
because the socket isn't available in most locations. | |
[Ryan Bloom] | |
*) Really reset the MaxClients value in worker and threaded | |
when the configured value is not a multiple of the number | |
of threads per child. We said we did previously but we | |
forgot to. [Jeff Trawick] | |
*) Add Debian layout. [Daniel Stone <daniel sfarc.net>] | |
*) If shared modules are requested and mod_so is not available, | |
produce a fatal config-time error. [Justin Erenkrantz] | |
*) Improve http2env's performance by cutting the work it has to | |
do. [Brian Pane <bpane pacbell.net>] | |
*) use new 'apr_hash_merge' function in mod_mime (performance fix) | |
[Brian Pane <bpane pacbell.net>] | |
Changes with Apache 2.0.28 | |
*) Fix infinite loop in mod_cgid.c. | |
[Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>] | |
*) When no port is given in a "ServerName host" directive, the | |
server_rec->port is now set to zero, not 80. That allows for | |
run-time deduction of the correct server port (depending on | |
SSL/plain, and depending also on the current setting of | |
UseCanonicalName). This change makes redirections | |
work, even with https:// connections. As in Apache-1.3, the | |
connection's actual port number is never used, only the ServerName | |
setting or the client's Host: setting. Documentation updated | |
to reflect the change. [Martin Kraemer] | |
*) Add a '%{note-name}e' argument to mod-headers, which works in | |
the same way as mod_log_confg. [Ian Holsman] | |
*) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and | |
AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard | |
MPMs. [Cliff Woolley] | |
*) Introduce htdbm, a user management utility for db/dbm authorization | |
databases. [Mladen Turk <mturk mappingsoft.com>] | |
*) Optimize usage of strlen and strcat in ap_directory_walk. | |
[Brian Pane <bpane pacbell.net>] | |
Changes with Apache 2.0.27 | |
*) Introduce an Apache mod_ssl initial configuration template | |
(ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall] | |
*) Fixed a memory leak in the getline parsing code that could | |
be triggered by arbitrarily large header lines. Requests | |
from the core input filter for single lines are now limited | |
to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert] | |
*) Fix a truncation bug in how we print the port on the Via: header. | |
The routine that prints the Via: header now takes a length for | |
the port string. [Zvi Har'El <rl math.technion.ac.il>] | |
*) Some syntax errors in mod_mime_magic's magic file can result | |
in a 500 error, which previously was unlogged. Now we log the | |
error. [Jeff Trawick] | |
*) Add the support/checkgid helper app, which checks the run-time | |
validity of group identifiers usable in the Group directive. | |
[Ken Coar] | |
*) Various --enable-so options have been fixed: --enable-so is | |
treated as "static"; explicit --enable-so=shared issues an error; | |
and explicit --enable-so fails with error on systems without | |
APR_HAS_DSO. [Aaron Bannert] | |
*) Fix a segfault in the core input filter when the client socket | |
gets disconnected unexpectedly. [Cliff Woolley] | |
*) Fix the reporting for child processes that die. This removes | |
all of the non-portable W* macros from Apache. | |
[Jeff Trawick and Ryan Bloom] | |
*) Win32: Track and display "Parent Server Generation:" in | |
mod_status output. The generation will be bumped at | |
server graceful restart, when the child process exits | |
by hitting MaxRequestsPerChild or if the child | |
process exits abnormally. [Bill Stoddard] | |
*) Win32: Fix problem where MaxRequestsPerChild directive was | |
not being picked up in favor of the default. Enable | |
the parent to start up a new child process immediately upon | |
the old child starting shutdown. | |
[Bill Stoddard] | |
*) Fix some bungling of the remote port in rfc1413.c so that | |
IdentityCheck retrieves the proper user id instead of failing | |
and thus always returning "nobody." | |
[Dick Streefland <Dick.Streefland xs4all.nl>] | |
*) Introduced thread saftey for mod_rewrite's internal cache. | |
[Brian Pane <bpane pacbell.net>] | |
*) Simplified mod_env's directives to behave as most directives are | |
expected, in that UnsetEnv will not unset a SetEnv and PassEnv | |
directive following that UnsetEnv within the same container. | |
Also provides a runtime startup warning if a PassEnv configured | |
environment value is undefined. [William Rowe] | |
*) The worker MPM is now completely ported to APR's new lock API. It | |
uses native APR types for thread mutexes, cross-process mutexes, | |
and condition variables. [Aaron Bannert] | |
*) Sync up documentation to remove all references to the now deprecated | |
Port directive. [Justin Erenkrantz] | |
*) Moved all ldap modules from the core to httpd-ldap sub-project | |
[Ryan Bloom] | |
*) Exit when we can't listen on any of the configured ports. This | |
is the same behavior as 1.3, and it avoids having the MPMs to | |
deal with bogus ap_listen_rec structures. [Jeff Trawick] | |
*) Cleanup the proxy code that creates a request to the origin | |
server. This change adds an optional hook, which allows modules | |
to gain control while the request is created if the proxy module | |
is loaded. The purpose of this hook is to allow modules to add | |
input and/or output filters to the request to the origin. While | |
I was at it, I made the core use this hook, so that proxy request | |
creation uses some of the code from the core. This can still be | |
greatly improved, but this is a good start. [Ryan Bloom] | |
Changes with Apache 2.0.26 | |
*) Port the MaxClients changes from the worker MPM to the threaded | |
MPM. [Ryan Bloom] | |
*) Fix mod_proxy so that it handles chunked transfer-encoding and works | |
with the new input filtering system. [Justin Erenkrantz] | |
*) Introduce the MultiviewsMatch directive, to allow the operator | |
to be flexible in recognizing Handlers and Filters filename | |
extensions as part of the Multiviews matching logic, strict with | |
MultiviewsMatch NegotiatedOnly to accept only filename extentions | |
that designate negotiated parameters, (content type, charset, etc.) | |
or MultiviewsAll for the 1.3 behavior of matching any files, even | |
if they have unregistered extensions. [William Rowe] | |
*) Fixed the configure script to add a LoadModule directive to | |
the default httpd.conf for any module that was compiled | |
as a DSO. [Aaron Bannert <aaron clove.org>] | |
*) rewrite mod_ssl input filtering to work with the new input filtering | |
system. [Justin Erenkrantz] | |
*) prefork: Don't segfault when we are able to listen on some but | |
not all of the configured ports. [Jeff Trawick] | |
*) Build mod_so even if no core modules are built shared. | |
[Aaron Bannert <aaron clove.org>] | |
*) Introduce ap_directory_walk rewrite (with further optimizations | |
required) to adapt to the ap_process_request_internal() changes. | |
Optimized so subrequests and redirects now reuse previous section | |
merges, until we mismatch with the original directory_walk, and | |
precomputed r->finfo results will cause directory_walk to skip | |
the most expensive phases of the function. [William Rowe] | |
*) Allow ApacheMonitor to connect to and control Apache on other | |
WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>] | |
*) Remove the Port directive. In it's place, the Listen directive | |
is now a required directive, which tells Apache what port to | |
listen on. The ServerName directive has also been extended | |
to accept an optional port. If the port is specified to the | |
ServerName, the server will report that port whenever it | |
reports the port that it is listening on. This change was | |
made to ease configuration errors that stem from having a Port | |
directive, and a Listen directive. In that situation, the server | |
would only listen to the port specified by the Listen command, | |
which caused a lot of confusion to users. [Ryan Bloom] | |
*) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32 | |
build, as loadable modules. [William Rowe] | |
*) Fix --enable-mods-shared processing. If most is specified, | |
then all modules that can be compiled as shared modules are. | |
[Aaron Bannert <aaron clove.org>] | |
*) Update the mime.types file to map video/vnd.mpegurl to mxu | |
and add commonly used audio/x-mpegurl for m3u extensions. | |
[Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht] | |
*) Eliminate the depreciated r->content_language, in favor of the array | |
r->content_languages introduced many years ago. Module authors must | |
substantially overhaul their modules, so this needs to be upgraded | |
if the module still relied on backwards-brokeness. [William Rowe] | |
*) Allow configure help strings to work with autoconf 2.50+ and 2.13. | |
[Justin Erenkrantz] | |
*) Rewrite the input filtering mechanisms to consolidate and reorganize | |
code. In short, core_input_filter does something now and | |
ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz] | |
*) Update the Win32 build to re-absorb mod_proxy and family. | |
[William Rowe] | |
*) Resolved the build failure on Win32 using MSVC 5.0 (without the | |
current SDK.) [William Rowe] | |
*) Some style changes to the code that does ProxyErrorOverride. Fixed | |
config merge behaviour. [Graham Leggett] | |
*) Allow support programs to be compiled against a static version | |
of libapr. This allows the smaller support programs to be | |
relocated. [Aaron Bannert <aaron clove.org>] | |
*) Update the mime.types file to the registered media types as | |
of 2001-09-25, and add mapping for xsl extension [Mark Cox] | |
*) Fix MaxClients in the Worker MPM, so that it specifies the maximum | |
number of clients that can connect at the same time, instead of | |
specifying the maximum number of child processes. | |
[Aaron Bannert <aaron clove.org>] | |
*) Switch proc_pthread AcceptMutex configuration directive to pthread to | |
be consistent with 1.3. [Justin Erenkrantz] | |
*) Cache apr_explode_localtime() value for 15 seconds. | |
[Brian Pane <bpane pacbell.net>] | |
*) Fix mod_include to not return ETag or Last-Modified headers. | |
[Ian Holsman <ianh cnet.com>] | |
*) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>] | |
*) Eliminate the wasteful run-time conversion of method names from strings | |
to numbers in places where the methods are known at compile time. | |
[Brian Pane <bpane pacbell.net>] | |
*) Turn the worker MPM's queue into a LIFO. This may | |
improve cache-hit performance under some conditions. | |
[Aaron Bannert <aaron clove.org>] | |
*) Switch back to SIGUSR1 for graceful restarts on all platforms that | |
support it. [Justin Erenkrantz] | |
*) Cleanup the worker MPM. We no longer re-use transaction | |
pools. This incurs less overhead than shuffling the pools | |
around so that they can be re-used. Remove one of the | |
queue's condition variables. We just redefined the API to | |
state that you can't try to add more stuff than you allocated | |
segments for. [Aaron Bannert <aaron clove.org>] | |
*) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>] | |
*) Fixed persistent connections when a request contains a body. | |
[Greg Stein] | |
*) mod_dav uses a new API to speak to the backend provider for dead | |
property management. [Greg Stein] | |
*) Remove the Win32 script-processing exception from mod_cgi, and | |
roll build_command_line/build_argv_list into a unified, overrideable | |
ap_cgi_build_command optional function. [William Rowe] | |
*) Rewrite find_start_sequence to use a better search algorithm | |
to find the start tag. [Justin Erenkrantz] | |
*) Fix a seg fault in mod_include. When we are generating an | |
internal redirect, we must set r->uri to "", not a bogus | |
string, and not NULL. [Ryan Bloom] | |
*) Optimized location_walk, so subrequests, redirects and second passes | |
now reuse previous section merges on a <Location > by <Location > | |
basis, until we mismatch with the original location_walk. | |
[William Rowe] | |
*) Back out the 1.45 change to util_script.c. This change made | |
us set the environment variable REQUEST_URI to the redirected | |
URI, instead of the originally requested URI. | |
[Taketo Kabe <kabe sra-tohoku.co.jp>] | |
*) Make mod_include do lazy evaluation of potentially expensive to | |
compute variables. [Brian Pane <bpane pacbell.net>] | |
*) Fix logging of bytes sent for HEAD requests. %b and %B should | |
log either - or 0, before this patch, they were both logging | |
the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>] | |
*) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather | |
than per character. [Brian Pane <bpane pacbell.net>] | |
*) Normalize the primary request, redirects and sub-requests to | |
run the same ap_process_request_internal for consistency in | |
robustness, behavior and security. [William Rowe] | |
*) Fix a segfault with mod_include when r->path_info is not set | |
(which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>] | |
*) Add -X functionality back. This indicates to all MPMs and any other | |
part of Apache that it should run in "debug" mode. [Justin Erenkrantz] | |
*) Some initial support for the cygwin platform [prefork only]. | |
This is not to be confused with support for the WinNT/Win32 | |
platform, which is the recommended configuration for native | |
Win32 users. The cygwin platform support is recommended for | |
cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>] | |
*) Changed syntax of Set{Input|Output}Filter. The list of filters | |
must be semicolon delimited (if more than one filter is given.) | |
The Set{Input|Output}Filter directive now overrides a parent | |
container's directive (e.g. SetInputFilter in <Directory /web/foo> | |
will override any SetInputFilter directive in <Directory /web>.) | |
This new syntax is more consistent with Add{Input|Output}Filter | |
directives defined in mod_mime. Also cures a bug in prior releases | |
where the Set{Input|Output}Filter directive would corrupt the | |
global configuration if the multiple directives were nested. | |
[William Rowe] | |
*) Cured what's ailed mime for quite some time. If an AddSomething | |
was given in the configuration (Language, Charset, Handler or | |
Encoding) Apache would set the content type as given by AddType, | |
but refused to check the mime.types file if AddType wasn't given | |
for that specific extension. Setting the AddHandler for .html | |
without setting the AddType text/html html would cause Apache to | |
use the default content type. [William Rowe] | |
*) Added some bulletproofing to memory allocation in the LDAP cache | |
code. [Graham Leggett] | |
Changes with Apache 2.0.25 | |
*) Move the installed /manual directory out of the /htdocs/ tree, so | |
that it can be kept more independently from the remaining document | |
root. The "Alias /manual ..." already allowed for easy projection | |
into existing private document trees. [Martin Kraemer] | |
*) Add specified user attributes to the environment when using | |
mod_auth_ldap. This allows you to use mod_include to embed specified | |
user attributes in a page like so: | |
Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you? | |
[Graham Leggett] | |
*) Fix a performance problem with the worker MPM. We now create | |
transaction pools once, and re-use them for each connection. | |
[Aaron Bannert <aaron clove.org>] | |
*) Modfied mod_mime to prevent mod_negotation from serving a multiview | |
of a 'handler' or 'filter', so that any filename extension that does | |
not contribute to the negotiated metadata can't be served without | |
an explicit request. E.g., if the .Z extension is associated with | |
an unzip filter, the user request somefile.Z.html, mod_negotiation | |
won't serve it. It can serve somefile.Z.html when somefile.Z is | |
requested, since the .Z extension is explictly requested, if the | |
.html extension is associated with ContentType text/html. | |
[William Rowe] | |
*) Introduce the AddInputFilter filter[;filter...] ext [ext...] | |
and corresponding AddOutputFilter syntax, to insert one or more | |
filters by mod_mime filename extension processing. | |
[William Rowe] | |
*) Fix a growing connection pool in core_output_filter() for | |
keepalive requests. [Jeff Trawick] | |
*) Moved split_and_pass_pretag_buckets back to being a | |
macro at Ryans's request. Removed the return from it | |
by setting and returning a return code instead. Updated | |
the code to check the return code from the macro and | |
do the right thing. [Paul J. Reder] | |
*) Fix a segfault when a numeric value was received for Host:. | |
[Jeff Trawick] | |
*) Add a function ap_remove_input_filter. This is to match | |
up with ap_remove_output_filter. [Ryan Bloom] | |
*) Clean up location_walk, so that this step performs a minimum | |
amount of redundant effort (it must be run twice, but it will no | |
longer reparse all <Location > blocks when the request uri | |
hadn't changed.) [William Rowe] | |
*) Eliminate proxy: (and all other 'special') processing from the | |
ap_directory_walk() phase. Modules that want to use special | |
walk logic should refer to the mod_proxy map_to_location example, | |
with it's proxy_walk and proxysection implementation. This makes | |
either directory_walk flavor much more legible, since that phase | |
only runs against real <Directory > blocks. | |
[William Rowe] | |
*) SECURITY: Fix a security problem in mod_include which would allow | |
an SSI document to be passed to the client unparsed. | |
[Cliff Woolley, Brian Pane] | |
*) Introduce the map_to_storage hook, which allows modules to bypass | |
the directory_walk and file_walk for non-file requests. TRACE | |
shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the | |
directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c. | |
[William Rowe] | |
*) Add the ability for mod_include to add the INCLUDES filter | |
if the file is configured for the server-parsed handler. | |
This makes the configuration for .shtml files much easier | |
to understand, and allows mod_include to honor Apache 1.3 | |
config files. Based on Doug MacEachern's patch to PHP | |
to do the same thing. [Ryan Bloom] | |
*) force OpenSSL to ignore process local-caching and to always | |
get/set/delete sessions using mod_ssl's callbacks | |
[Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, | |
Geoff Thorpe <geoff geoffthorpe.net>] | |
*) Make the worker MPM shutdown and restart cleanly. This also | |
cleans up some race conditions, and gets the worker using | |
pools more cleanly. [Aaron Bannert <aaron clove.org>] | |
*) Implement CRYPTO_set_locking_callback() in terms of apr_lock | |
for mod_ssl | |
[Madhusudan Mathihalli <madhusudan_mathihalli hp.com>] | |
*) Fix for mod_include. Ryan's patch to check error | |
codes put a return in the wrong place. Also, the | |
include handler return code wasn't being checked. | |
I don't like macros with returns, so I converted | |
SPLIT_AND_PASS_PRETAG_BUCKETS into a function. | |
[Paul J. Reder <rederpj raleigh.ibm.com>] | |
*) fix segv in mod_mime if no AddTypes are configured | |
[John Sterling <sterling covalent.net>] | |
*) Enable ssl client authentication at SSL_accept time | |
[Madhusudan Mathihalli <madhusudan_mathihalli hp.com>] | |
*) Fix a segfault in mod_include when the original request has no | |
associated filename (e.g., we're filtering the error document for | |
a bad URI). [Jeff Trawick] | |
*) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick] | |
*) The prefork and OS/2 MPMs are overwriting the pid file when a second copy | |
of httpd is started and shuts down due to socket conflict. Moving the | |
call to ap_log_pid solves the problem. | |
*) Changed the late-1.3 log_config substitution %c to %X, to log the | |
status of the closed connection, as it conflicts with the far more | |
common, historical ssl logging directive %...{var}c. [William Rowe] | |
*) Added the common error/ tree to the build/install targets | |
(similar to the common icons/ tree) for the multi-language error | |
messages that Lars committed earlier. [William Rowe] | |
*) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard] | |
*) Added a default commented-out mod_ldap and mod_auth_ldap | |
configuration to httpd-std.conf and httpd-win.conf | |
[Graham Leggett] | |
*) Added documentation for mod_ldap and mod_auth_ldap. | |
[Graham Leggett] | |
*) Enabled negative caching on attribute comparisons in the LDAP cache. | |
Fixed a problem where the default cache TTL was set in milliseconds | |
not microseconds causing the cache to time out almost immediately. | |
[Graham Leggett] | |
*) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP | |
module code to follow APR. [Graham Leggett] | |
*) Fixed LDAP cleanup on graceful restarts. LDAP connections are now | |
cleaned up when the connection pool pool is cleaned up. | |
[Graham Leggett] | |
*) Fix a minor issue with Jeff Trawick's mod_include | |
patch. Without this patch, the code will just allocate | |
more bytes in get_combined_directive than are needed. | |
[Paul Reder] | |
*) Added the LDAP authentication module mod_auth_ldap. | |
[Dave Carrigan <dave rudedog.org>, Graham Leggett] | |
*) Added the LDAP cache and connection pooling module mod_ldap. | |
[Dave Carrigan <dave rudedog.org>, Graham Leggett] | |
*) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest | |
by allowing a module to disable itself if its prerequisites are not | |
met. [Justin Erenkrantz] | |
Changes with Apache 2.0.24 | |
*) Fix a couple of issues in mod_include when the tag appeared at | |
offsets near 8192 in the file being parsed. [Jeff Trawick] | |
*) Fix an assertion failure in mod_ssl when the keepalive timeout is | |
reached. [Jeff Trawick] | |
*) Numerous improvements to the Win32 build system. Introduced command line | |
builds without requiring .mak files for MSVC 6.0 and later versions. | |
Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users. | |
[William Rowe] | |
*) Assorted corrections and improvements to the winnt_mpm startup code. Better | |
reporting of uninstalled services and other error conditions, and changed the | |
default service name to Apache2. [William Rowe] | |
*) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm | |
compatibility with existing Apache 1.3 Win32 Apache management utilites. | |
[Mladen Turk <mturk mappingsoft.com>, William Rowe] | |
*) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20. | |
[William Rowe, Greg Ames] | |
*) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage | |
and RemoveCharset directives. [William Rowe] | |
*) The Unix MPMs other than perchild now allow child server | |
processes to use the accept mutex when starting as root and | |
using SysV sems for the accept mutex. Previously, this | |
combination would lead to fatal errors in the child server | |
processes. perchild can't use SysV sems because of security | |
issues. [Jeff Trawick, Greg Ames] | |
*) Added Win32 revision stamp resources to all http binaries | |
(including modules/ and support/ tools.) PR7322 [William Rowe] | |
*) Fix ap_rvprintf to support more than 4K of data at one time. | |
[Cody Sherr <csherr covalent.net>] | |
*) We have always used the obsolete/deprecated Netscape syntax | |
for our tracking cookies; now the CookieStyle directive | |
allows the Webmaster to choose the Netscape, RFC2109, or | |
RFC2965 format. The new CookieDomain directive allows the | |
setting of the cookie's Domain= attribute, too. PR #s 5006, | |
5023, 5920, 6140 [Ken Coar] | |
*) Tweak server/Makefile so that the rules for generating exports.c | |
are compatible with make utilities which don't expand wildcards | |
in a dependency list (e.g., OS/390 make, certain levels of GNU | |
make). [Jeff Trawick] | |
*) Install the SSL headers. [John Sterling <sterling covalent.net>] | |
*) Begin to sanitize the MPM configuration directives. Now, all | |
MPMs use the same functions for all common MPM directives. This | |
should make it easier to catch all bugs in these directives once. | |
[Cody Sherr <csherr covalent.net>] | |
*) Close a major resource leak. Every time we had issued a | |
graceful restart, we leaked a socket descriptor. | |
[Ryan Bloom] | |
*) Fix a problem with the new method code. We need to cast | |
the 1 to an apr_int64_t or it will be treated as a 32-bit | |
integer, and it will wrap after being shifted 32 times. | |
[Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>] | |
*) Fix a bug in mod_expires. Previous to this patch, if you | |
told mod_expires to add 604800 seconds to the last-modified | |
time, it actually added 604800 usec's to the last-modified time, | |
so that when looking at the response it looked like nothing | |
had been done. The root of the problem was that we always compute | |
time in usec's, but we ask users to input sec's. This means we | |
need to convert to usec's before using those values. | |
[Ryan Bloom] | |
*) The worker MPM now handles shutdown and restart requests. It | |
definitely isn't perfect, but we do stop the servers correctly. | |
The biggest problem right now is that SIGHUP causes the server to | |
just die. [Ryan Bloom] | |
Changes with Apache 2.0.23 | |
*) Use the prefork MPM by default on Unix. [various] | |
*) Added a systray icon monitor application for Win32. | |
[Mladen Turk <mturk mappingsoft.com>] | |
*) mod_rewrite: Fix the line ending on some non-Unix systems for | |
messages written to the rewrite log. | |
[Richard Labennett <rlabenn us.ibm.com>] | |
*) All mod_autoindex query parsing is now quietly quashed with the | |
IndexOption IgnoreClient. The IndexOption SuppressColumnSorting | |
still drops the column sort <a href>'s for the column headers, but | |
IgnoreClient is required to ignore these Query options entirely. | |
[William Rowe] | |
*) Introduced new mod_autoindex query argument parsing for F=[0|1|2] | |
to allow the client to select plain, FancyIndexing or HTMLTable | |
formatting, V=[0|1] to inhibit or enable version sorting, and | |
P=pattern to return only specific files. The old Query Arguments | |
were reorganized as C=f for sorting column 'f' (same N, D, S, or M | |
as before), and O=A|D for ordering ascending or descending. | |
[William Rowe] | |
*) Fixed an error in mod_include's directive parsing routines which | |
caused #if, #elif, and #else expressions containing backslashes | |
to be improperly evaluated. [Cliff Woolley] | |
*) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to | |
drop the icon column, SuppressRules to drop the <hr> elements, | |
and HTMLTable to create rudimentary HTML table listings (implies | |
FancyIndexing). [William Rowe] | |
*) Re-introduced the mod_autoindex IndexOptions flag TrackModified | |
from Apache 1.3.15. This is needed for two reasons, first, given | |
multiple machines within a server farm, ETags and Last-Modified | |
stamps won't correspond from machine to machine, and second, many | |
Unixes don't capture changes to the date or time stamp of existing | |
files, since these don't modify the dirent itself. [William Rowe] | |
*) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst | |
and DirectoryWidth options from Apache 1.3.10. | |
[William Rowe, Ken Coar] | |
*) Eliminated FancyIndexing directive, deprecated early in Apache | |
1.3 by the IndexOptions FancyIndexing syntax. [William Rowe] | |
*) mod_autoindex now excludes any file names that would result in | |
an error, other than a success or redirect. Also optimized | |
the parent directory, always included except in the URI '/'. | |
[William Rowe] | |
*) Refactored mod_negotiation and mod_mime to help mod_dir accept | |
negotiated index pages, and prevent the server from defaulting | |
to an autoindex of the directory. mod_negotiation will now die | |
with a 500 Internal Error if it could match some filenames | |
(e.g. for mod_dir) but none can be served. mod_negotation now | |
refuses to serve any file with an extention that mod_mime doesn't | |
recognize, and wasn't part of the request. [William Rowe] | |
*) Eliminate mod_cgi's handling of .exe files without the .exe file | |
extension. This is already handled by multiviews, if the admin | |
wishes to AddHandler .exe or define a content type handler and | |
associate .exe files with that content type. Multiviews must be | |
enabled to allow these to be served. [William Rowe] | |
*) Speed up the server's response to a spike in incoming workload | |
or restarts by assigning empty scoreboard slots to new processes | |
when they are available. [Greg Ames] | |
*) Add a handler to mod_includes.c. This handler is designed to | |
implement the XbitHack directive. This can't be done with a | |
fixup, because we need to check the content-type, which is | |
only available in the handler phase. [Ryan Bloom] | |
*) Make the includes filter check return codes from filters lower in | |
the filter chain. If a lower level filter returns an error, then | |
the request needs to stop immediately. This allows mod_include to | |
stop parsing data once a lower filter recognizes an error. | |
[Ryan Bloom] | |
*) Add the ability to extend the methods that Apache understands | |
and have those methods <limit>able in the httpd.conf. It uses | |
the same bit mask/shifted offset as the original HTTP methods | |
such as M_GET or M_POST, but expands the total bits from an int to | |
an ap_int64_t to handle more bits for new request methods than | |
an int provides. [Cody Sherr <csherr covalent.net>] | |
*) Fix broken mod_mime behavior in merging its arguments. Possible | |
cause of unexplicable crashes introduced in 2.0.20. [William Rowe] | |
*) Solve many mod_ssl porting issues (too many to detail) with | |
help from the whole team, but most notably [Ralf S. Engelschall, | |
Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, | |
Doug MacEachern, William Rowe, Cliff Woolley] | |
*) More stall fixes for the threaded & worker mpm's. | |
Make mod_status output more accurate. Don't | |
count workers in processes which aren't actively | |
serving requests. [Greg Ames] | |
*) Win32: Get SSI exec cgi tag working. [Bill Stoddard] | |
*) Add a single listener/multiple worker MPM. This MPM is | |
definately not fully correct, but it allows us to solve many | |
of the problems that exist in the threaded MPM. This is a | |
modified version of the threaded MPM. [Ryan Bloom] | |
*) Improve content generation throughout Apache, providing closer | |
compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0 | |
Transitional specifications. [William Rowe] | |
Changes with Apache 2.0.22 | |
*) Fix a problem where the threaded MPM stalls after restarts or | |
segfaults. Also prevent multiple active processes from using | |
the same scoreboard slot. [Greg Ames] | |
*) Apache/Win32 now fills in the service description with Apache's | |
server version string, including loaded and advertised modules. | |
[William Rowe] | |
*) Improved support for the Win32 build, to recover gracefully from | |
missing apr or apr-util directories or the awk interpreter, | |
create the proper cgi-bin examples, including a test-cgi.bat, and | |
fix the perl shebang line for printenv.pl, when installing from | |
the build environment. [William Rowe] | |
*) Fix a segfault in threaded.c caused by passing uninitialized | |
apr_thread_t * to apr_thread_join(). [Jeff Trawick] | |
*) Use new APR number conversion functions to reduce CPU consumption | |
when setting the content length, and in mod_log_config. | |
[Brian Pane] | |
*) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp> | |
where HEAD response headers were being repeated twice for | |
files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This | |
problem in the http_header filter was exposed by the recent rewrite | |
of the content_length filter. [Taketo Kabe, Bill Stoddard] | |
*) Fix seg faults in mod_status with ExtendedStatus enabled, after | |
restarts. A garbage pointer to a vhost's server_rec from the | |
previous generation was being left around under certain | |
conditions. [Greg Ames] | |
*) Fix a cosmetic problem with mod_include. Non-existant SSI vars | |
used to appear as '(none', without the closing paren. | |
[Günter Knauf <eflash gmx.net>] | |
*) Improve the exports generating awk script. In the past, we had | |
work around problems in the awk script by avoiding some #if and | |
#ifdefs. This has bitten us many times in generating the exports.c | |
file. This improvement allows corrects the header file parsing. | |
[Sander Striker <striker apache.org>] | |
Changes with Apache 2.0.21 | |
*) Resolve the Win32 htpasswd bug, where a file that existed would be | |
overwritten, regardless of the -c flag. | |
[William Rowe, Mladen Turk <mladen.turk mail.inet.hr>] | |
*) Introduce connection sub-pools into ab. Truncating the lifetime | |
of these allocations means that ab no longer perpetually grows | |
its working set, running out of memory on large request attempts. | |
[William Rowe] | |
*) Make scoreboard creation a hook. This allows management | |
modules to have access to the scoreboard at the time that it is | |
created, and at every restart request. | |
[Cody Sherr <csherr covalent.net>] | |
*) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and | |
added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest | |
daemon index actually used in the scoreboard. I also | |
updated the pertinent calls. [Paul J. Reder] | |
*) Win32: Prevent listening sockets from being inherited by | |
the Apache child process, CGI scripts, rotatelog process | |
etc. If the Apache child process segfaults, any processes | |
that the child started are not reaped. Prior to this fix, | |
these processes inherited the listening sockets which sometimes | |
prevented the restarted Apache child process from accepting | |
connections (ie, the server would hang). | |
[Bill Stoddard] | |
*) Provide vhost and request strings when ExtendedStatus is on. | |
[Greg Ames] | |
*) Fix some issues with the pod and prefork: check the pod *after* | |
processing a connection so that a server processing a time- | |
consuming request bails out as soon as practical; when the | |
parent process wakes up a server process via connect(), use an | |
APR timeout on the connect() so that we don't hang for a long | |
time if there aren't server processes around to do accept(). | |
[Jeff Trawick, Greg Ames] | |
*) Performance improvement to mod_mime.c. find_ct() in mod_mime, | |
spends a lot of time in apr_table_get calls. Using the default | |
httpd.conf, the tables for languages and charsets are somewhat | |
large, so the time spent scanning them on each request is | |
significant. Replacing the tables with hash tables provides | |
a nice speedup. [Brian Pane <bpane pacbell.net>] | |
*) Add two functions to allow modules to access random parts of the | |
scoreboard. This allows modules compiled for one MPM to access the | |
scoreboard, even if it the server was compiled for another MPM. | |
[Harrie Hazewinkel <harrie covalent.net>] | |
Changes with Apache 2.0.20 | |
*) Fix problem in content-length filter where the filter would | |
buffer all the output from a CGI before sending any bytes | |
down the filter stack to the network. This problem would cause | |
significant memory consumption if the CGIs generated | |
lots of bytes. [Bill Stoddard] | |
*) Get non-blocking CGI pipe reads working with the bucket brigades. | |
[Bill Stoddard] | |
*) Fix seg fault on Windows when serving files cached with mod_file_cache. | |
[Bill Stoddard] | |
*) Fix a bug in the threaded MPM that would cause it to kill off all | |
workers immediately after starting if the number of workers started | |
was above a certain threshold. [Ryan Bloom, Bill Stoddard] | |
Changes with Apache 2.0.19 | |
*) Fix problem with threaded MPM. The problem was that if each child | |
process was busy serving a single long-lived request and the server | |
was sent a graceful restart signal, the server would stop serving | |
requests. This would happen because each child process would wait to | |
die until the last thread was done, and the parent wouldn't spawn any | |
new children until a process died. Now, the parent looks at the fact | |
that the children are dying gracefully, and starts new children. | |
Those new children only start enough threads to compliment the number | |
of threads in the other child process that shares the same spot in | |
the scoreboard. In this way, we make sure to never go over | |
MaxClients. [Ryan Bloom] | |
*) modified mod_negotiation and mod_autoindex to speed up by almost a | |
factor of two on apr_dir_read()-enhanced platforms, such as Win32 | |
and OS2, by calling ap_sub_request_lookup_dirent() with the results | |
already provided by apr_dir_read(). [William Rowe] | |
*) mod_file_cache is now more robust to filtering and serves requests | |
slightly more efficiently. [Cliff Woolley] | |
*) Fix problem handling FLUSH bucket in the chunked encoding filter. | |
Module was calling ap_rwrite() followed by ap_rflush() but the | |
served content was not being displayed in the browser. Inspection | |
of the output stream revealed that the first data chunk was | |
missing the trailing CRLF required by the RFC. [Bill Stoddard] | |
*) apxs no longer generates ap_send_http_header() in the example handler | |
*) Fix an ab problem which could cause a divide-by-zero exception | |
with certain invocations (e.g., ab -k -c 6 -n 100 localhost/). | |
[Ian Holsman <ianh cnet.com>] | |
*) Solve case-insensitive platforms' confusion about negotiated | |
filenames, allowing files of differnt case to match in choosing | |
the document to serve. [William Rowe] | |
*) Fix brokenness when ThreadsPerChild is higher than the built-in | |
limit. We left ap_threads_per_child at the higher value which | |
led to segfaults when doing certain scoreboard operations. | |
[Jeff Trawick] | |
*) Fix seg faults and/or missing output from mod_include. The | |
default_handler was using the subrequest pool for files and | |
MMAPs, even though the associated APR structures typically | |
live longer than the subrequest. [Greg Ames] | |
*) Extend mod_setenvif to support specifying regular expressions | |
on the SetEnvIf (and SetEnvIfNoCase) directive attribute field. | |
Example: SetEnvIf ^TS* [a-z].* HAVE_TS | |
will cause HAVE_TS to be set if any of the request headers begins | |
with "TS" and has a value that begins with any character in the | |
set [a-z]. [Bill Stoddard] | |
*) httpd children now re-bind themselves to a random CPU on | |
multiprocessor systems on AIX via bindprocessor() in 2.0. | |
[Victor J. Orlikowski] | |
*) Fix htdigest. It would go into a loop in getline when adding | |
a second user. [Bill Stoddard] | |
*) Win32 platforms now fully support mod_userdir options. [Will Rowe] | |
*) Automatically generate httpd.exp for AIX. | |
DSOs now work again on AIX in 2.0 | |
[Victor J. Orlikowski] | |
*) Add a new request hook, error_log. This phase allows modules | |
to act on the error log string _after_ it has been written | |
to the error log. The goal for this hook is to allow monitoring | |
modules to send the error string to the monitoring agent. | |
[Ryan Bloom] | |
*) Modify mod_echo to make it use filters for input and output. | |
[Ryan Morgan <rmorgan covalent.net>] | |
*) Extend mod_headers to support conditional driven Header | |
add, append and set. Use SetEnvIf to set an envar and conditionally | |
add/append/set headers based on this envar thusly: | |
SetEnvIf TSMyHeader value HAVE_TSMyHeader | |
Header add MyHeader "%t %D" env=HAVE_TSMyHeader | |
If the request contains header "TSMyHeader: value" then header | |
MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response. | |
[Bill Stoddard] | |
*) Extend mod_headers to support using format specifiers on Header | |
add, append and set header values. Two format specifiers are supported: | |
%t - reports, in UTC microseconds since the epoch, when the | |
request was received. | |
%D - reports the time, in microseconds, between when the request was | |
received and the response sent. | |
Examples: | |
Header add MyHeader "This request served in %D microseconds. %t" | |
results in a header being added to the response that looks like this: | |
MyHeader: This request served in D=5438 microseconds. t=991424704447256 | |
[Bill Stoddard] | |
*) Fix reset_filter(). We need to be careful how we remove filters. | |
If we set r->output_filters to NULL, we also have to reset the | |
connection's filters. [John Sterling] | |
*) Optimise reset_filter() in http_protocol.c. [Greg Stein] | |
*) Add a check to ap_die() to make sure the filter stack is sane and | |
contains the correct basic filters when an error occurs. This fixes | |
a problem where headers are not being sent on error. [John Sterling] | |
*) New Header directive 'echo' option. "Header echo regex" will | |
cause any headers received on the request that match regex to be | |
echoed to (included in) the response headers. | |
[Bill Stoddard] | |
*) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H. | |
This prevented the inclusion of apr_compat.h. PR #7773 | |
[Oleg Broytmann <phd phd.pp.ru>] | |
*) Moved util_uri to the apr-util library. This required a bunch of | |
apr_name changes for the uri utility functions. [Justin Erenkrantz] | |
*) Move the addition of default AP_HTTP_HTTP_HEADER filters to the | |
insert_filter phase so that other filters are not bypassed by default. | |
[Graham Leggett] | |
*) Reimplement mod_headers as an output filter. mod_headers can now | |
add custom headers to inbound requests using the RequestHeader directive | |
and to responses using the same old Header directive. [Graham Leggett] | |
Changes with Apache 2.0.18 | |
*) Fix command-line processing so that if a bad argument is specified | |
Apache will exit. [Jeff Trawick] | |
*) Change the make targets and rules to be consistent in all of the | |
Apache-owned source trees. [Roy Fielding] | |
*) Fix processing of the TRACE method. Previously we passed bogus | |
parms to form_header_field() and it overlaid some vhost structures, | |
resulting in a segfault in check_hostalias(). | |
[Greg Ames, Jeff Trawick] | |
*) Win32: Add support for reliable piped logs. If the logging process | |
goes down, Apache will automatically restart it. This function has | |
been part of Apache on Unix/Linux/BSD since the early v1.3 releases. | |
[Bill Stoddard] | |
*) Do not start piped log processes during the config file | |
preflight. This change also circumvents a problem on | |
Windows where the rotatelog processes created during preflight | |
was not getting cleaned up properly. | |
[Bill Stoddard] | |
*) add "Request Phase Participation" info to mod_info | |
[Doug MacEachern] | |
*) Make first phase changes to the scoreboard data structures in | |
preparation for the rewriting of the scoreboard per my posted | |
design notes. [Paul J. Reder] | |
*) Fix httpd's definition of LTFLAGS to be consistent with that of apr | |
and apr-util, allow it to be overridden by the configure command-line | |
(default="--silent") and introduce LT_LDFLAGS to replace what we were | |
formerly abusing as LTFLAGS. [Roy Fielding] | |
*) Clean up the reporting of incorrect closing container tags. | |
[Barrie Slaymaker <barries slaysys.com>] | |
*) Simplify the configure process by moving all libtool stuff to APR | |
and moving hints.m4 inline. [Roy Fielding] | |
*) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types | |
of functions used by mod_proxy for export in the DLL | |
[Ian Holsman <IanH cnet.com>] | |
*) Prevent a hang when a cgi handled by mod_cgid tries to read a | |
request body from its stdin but no reqest body is being written to | |
the cgi. [Jeff Trawick] | |
*) mod_log_config: %c connection status incorrectly logged | |
as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0. | |
[Bill Stoddard] | |
*) Get mod_cern_meta working under Windows | |
[Bill Stoddard] | |
*) Create Files, and thus MMAPs, out of the request pool, not the | |
connection pool. This solves a small resource leak that had us | |
not closing files until a connection was closed. In order to do | |
this, at the end of the core_output_filter, we loop through the | |
brigade and convert any data we have into a single HEAP bucket | |
that we know will survive clearing the request_rec. | |
[Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>, | |
Cliff Woolley] | |
*) Completely revamp configure so that it preserves the standard make | |
variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving | |
the configure additions to EXTRA_* variables. Also, allow the user | |
to specify NOTEST_* values for all of the above, which eliminates the | |
need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting | |
of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to | |
avoid pointless duplications. Fix the order in which flags are given | |
on the compile and link lines. Remove obsolete macros APR_DOEXTRA, | |
AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE. | |
Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros. | |
Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding] | |
*) Get mod_tls to compile/work better on Windows. PR #7612 | |
[Bernhard Schrenk <b.schrenk improx.com>] | |
*) Fix shutdown/restart hangs in the threaded MPM. | |
[Jeff Trawick, Greg Ames, Ryan Bloom] | |
*) Removed the keptalive boolean from conn_rec because it is now only | |
used by a single routine and can be replaced by a local variable. | |
[Greg Stein, Ryan Bloom, Roy Fielding] | |
*) Patch prefork to put enough of the signal processing back in so that | |
signals are all handled properly now. The previous patch fixed the | |
deadlock race condition, but broke the user directed signal handling. | |
This fixes it to work the way it did before my previous prefork patch | |
(primarily, SIGTERM is now working). | |
*) Change how input filters decide how much data is returned to the | |
higher filter. We used to use a field in the conn_rec, with this | |
change, we use an argument to ap_get_brigade to determine how much | |
data is retrieved. [Ryan Bloom] | |
*) Fix seg fault at start-up introduced by Ryan's change to enable | |
modules to specify their own logging tags. mod_log_config | |
registers an optional function, ap_register_log_handler(). | |
ap_register_log_handler() was being called by http_core before | |
the directive hash table was created. This patch creates the | |
directive hash table before ap_register_log_handler() is | |
registered as an optional function. | |
[jean-frederic clere <jfrederic.clere fujitsu-siemens.com>] | |
*) Add ap_set_int_slot() function | |
[John K. Sterling <sterling covalent.net>] | |
*) Under certain circumstances, Apache did not supply the | |
right response headers when requiring authentication. | |
[Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114 | |
(This is a port of the change that went into Apache 1.3.19.) | |
*) Allow modules to specify their own logging tags. This basically | |
allows a module to tell mod_log_config that when %x is encountered | |
a specific function should be called. Currently, x can be any single | |
character. It may be more useful to make this a string at some point. | |
[Ryan Bloom] | |
Changes with Apache 2.0.17 | |
*) If a higher-level filter handles the the byterange aspects of a | |
request, then the byterange filter should not try to redo the | |
work. The most common case of this happening, is a byterange | |
request going through the proxy, and the origin server handles | |
the byterange request. The proxy should ignore it. | |
[Graham Leggett <minfrin sharp.fm>] | |
*) Changed the threaded mpm to have child_main join to each of the | |
worker threads to make sure the kids are all gone before child_main | |
exits after a signal (cleanup from perform_idle_server_maintenance). | |
This is an extension of Ryans recent commit to make the child_main | |
the signal thread. | |
*) Add more options to the ap_mpm_query function. This also allows MPMs to | |
report if their threads are dynamic or static. Finally, this also | |
implements a new API, ap_show_mpm, which returns the MPM that was | |
required into the core. [Harrie Hazewinkel <harrie covalent.net>] | |
*) Do not install the binaries from the support directory twice. | |
[jun-ichiro hagino <itojun iijlab.net>] | |
*) The ap_f* functions should flush data to the filter that is passed | |
in, not the the filter after the one passed in. | |
[Ryan Morgan <rmorgan covalent.net>] | |
*) Make ab work again by changing its native types to apr types and formats. | |
[Justin Erenkrantz <jerenkrantz ebuilt.com>] | |
*) Move the byterange filter and all of the supporting functions back | |
to the HTTP module. The byterange filter turned out to be very | |
HTTP specific, and it belongs in the HTTP module. [Greg Stein] | |
*) Make clean, distclean, and extraclean consistently according to the | |
Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>] | |
*) Fix errors in the renaming of the apr_threadattr_detach_xxx functions. | |
This may have been causing problems stopping processes in the threaded | |
mpm's. [Greg Ames] | |
*) Fix content-length in mod_negotiation to a long int representation. | |
[William Rowe] | |
*) Remove BindAddress from the default config file. | |
[<giles nemeton.com.au>] | |
*) Allow module authors to add a module to their Apache build using | |
--with-module, without re-running buildconf. The syntax is: | |
--with-module=module_type:/path/to/module.c | |
The configure script will copy the module.c file to | |
modules/module_type, and it will be added to the relevant Makefiles. | |
currently, this only works for static modules. [Ryan Bloom] | |
*) Changes required to make prefork clean up idle children properly. | |
There was a window during which a starting worker deadlocks when | |
an idle cleanup arrives before it completes init. Apache then keeps | |
trying to cleanup the same deadlocked worker forever (until higher | |
pids come along, but it still will never reduce below the deadlocked | |
pid). Thus the number of children would not reduce to the correct | |
idle level. [Paul J. Reder] | |
Changes with Apache 2.0.16 | |
*) Change the default installation directory to /usr/local/apache2, | |
as now defined by the "Apache" layout in config.layout. [Marc Slemko] | |
*) OS/2: Added support for building loadable modules as OS/2 DLLs. | |
[Brian Havard] | |
*) Get MaxRequestsPerChild working with the Windows MPM. | |
[Bill Stoddard] | |
*) Make generic hooks to work, with mod_generic_hook_import/export | |
experimental modules. [Ben Laurie, Will Rowe] | |
*) Fix segfaults for configuration file syntax errors such as | |
"<Directory>" followed by "</Directory" and | |
"<Directory>" followed by "</Directoryz>". [Jeff Trawick] | |
*) Cleanup the --enable-layout option of configure. This makes | |
us use a consistent location for the config.layout file, and it | |
makes configure more portable. | |
[jun-ichiro hagino <itojun iijlab.net>] | |
*) Changes to 'ab'; fixed int overrun's, added statistics, output in | |
csv/gnuplot format, rudimentary ssl support and various other tweaks | |
to make results more true to what is measured. The upshot of this it | |
turns out that 'ab' has often underreported the true performance of | |
apache. Often by a order of magnitude :-) See talk/paper of Sander | |
Temme at April ApacheCon 2001 for details. | |
[Dirk-Willem van Gulik] | |
*) Clean up mod_cgid's temporary request pool. Besides fixing a | |
storage leak this ensures that some unnecessary pipes are closed. | |
[Jeff Trawick] | |
*) Performance: Add quick_handler hook. This hook is called at the | |
very beginning of the request processing before location_walk, | |
translate_name, etc. This hook is useful for URI keyed content | |
caches like Mike Abbott's Quick Shortcut Cache. | |
[Bill Stoddard] | |
*) top_module global variable renamed to ap_top_module [Perl] | |
*) Move ap_set_last_modified to the core. This is a potentially | |
controversial change, because this is kind of HTTP specific. However | |
many protocols should be able to take advantage of this kind of | |
information. I expect that headers will need one more layer of | |
indirection for multi-protocol work, but this is a small step in | |
the right direction. [Ryan Bloom] | |
*) Enable mod_status by default. This matches what Apache 1.3 does. | |
[Ed Korthof] | |
*) Add a ScriptSock directive to the default config file. This is | |
only enabled when mod_cgid is used. | |
[Taketo Kabe <kabe sra-tohoku.co.jp>] | |
Changes with Apache 2.0.15 | |
*) Untangled the buildconf script and eliminated the need for build's | |
aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other | |
libtool muck that is now under srclib/apr/build. [Roy Fielding] | |
*) Win32: Don't accept more connections than we have worker threads | |
to handle. | |
[Bill Stoddard] | |
*) Fix bug in the Unix threaded.c MPM that allowed child processes | |
to fork() new child processes. | |
[Bill Stoddard] | |
*) SECURITY: Fix a major security problem with double-reverse lookup | |
checking. Previously, a client connecting over IPv4 would not be | |
matched properly when the server had an IPv6 listening socket. | |
PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>] | |
*) Change the way the beos MPM handles polling to allow it to stop and | |
restart. Problem was the sockets being polled were being reset by | |
the select call, so once it had accepted a connection it was no | |
longer listening on the UDP socket we use for shutdown instructions. | |
APR needs to be altered, patch on it's way. [David Reid] | |
*) Empty out the brigade shared by ap_getline()/ap_get_client_block() | |
on error exit from ap_getline(). Some other code got upset because | |
the wrong data was in the brigade. [Greg Ames, Jeff Trawick] | |
*) Handle ap_discard_request_body() being called more than once. | |
[Greg Ames, Jeff Trawick] | |
*) Get rid of an inadvertent close of file descriptor 2 in | |
mod_mime_magic. [Greg Ames, Jeff Trawick] | |
*) Add a hook, create_request. This hook allows modules to modify | |
a request while it is being created. This hook is called for all | |
request_rec's, main request, sub request, and internal redirect. | |
When this hook is called, the the r->main, r->prev, r->next | |
pointers have been set, so modules can determine what kind of | |
request this is. [Ryan Bloom] | |
*) Cleanup the build process a bit more. The Apache configure | |
script no longer creates its own helper scripts, it just | |
uses APR's. | |
[jean-frederic clere <jfrederic.clere fujitsu-siemens.com>] | |
*) Stop the forced downgrade of the connection to HTTP/1.0 for | |
proxy requests. [Graham Leggett] | |
*) Avoid using sscanf to determine the HTTP protocol number in | |
the common case because sscanf is a performance hog. From | |
Mike Abbot's Accelerating Apache patch number 6. | |
[Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard] | |
*) SECURITY: Fix a security exposure in mod_access. Previously when | |
IPv6 listening sockets were used, allow/deny-from-IPv4-address rules | |
were not evaluated properly (PR #7407). Also, add the ability to | |
specify IPv6 address strings with optional prefix length on Allow | |
and Deny. [Jeff Trawick] | |
*) Enhance rotatelogs so that a UTC offset can be specified, and | |
the logfile name can be formatted using strftime(3). (Brought | |
forward from 1.3.) [Ken Coar] | |
*) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling | |
DuplicateHandle on an IOCompletionPort (a practice which | |
MS "discourages"). The new model does not rely on associating | |
the completion port with the listening sockets, thus the | |
completion port can be completely managed within the child | |
process. A dedicated thread accepts connections off the network, | |
then calls PostQueuedCompletionStatus() to wake up worker | |
threads blocked on the completion port. | |
[Bill Stoddard] | |
*) Bring forward the --suexec-umask option which allows the | |
builder to preset the umask for suexec processes. [Ken Coar] | |
*) Add a -V flag to suexec, which causes it to display the | |
compile-time settings with which it was built. (Only | |
usable by root or the AP_HTTPD_USER username.) [Ken Coar] | |
*) Mod_include should always unset the content-length if the file is | |
going to be passed through send_parsed_content. There is no to | |
determine if the content will change before actually scanning the | |
entire content. It is far safer to just remove the C-L as long | |
as we are scanning it. [Ryan Bloom] | |
*) Make sure Apache sends WWW-Authenticate during a reverse proxy | |
request and not Proxy-Authenticate. | |
[Graham Leggett <minfrin sharp.fm>] | |
Changes with Apache 2.0.14 | |
*) Fix content-length computation. We ONLY compute a content-length if | |
We are not in a 1.1 request and we cannot chunk, and this is a keepalive | |
or we already have all the data. [Ryan Bloom] | |
*) Report unbounded containers in the config file. Previously, a typo | |
in the </container> directive could result in the rest of the config | |
file being silently ignored, with undesired defaults used. | |
[Jeff Trawick] | |
*) Make the old_write filter use the ap_f* functions for the buffering. | |
[Ryan Bloom] | |
*) Move more code from the http module into the core server. This | |
is core code, basically the default handler, the default input | |
and output filters, and all of the core configuration directives. | |
All of this code is required in order for the server to work, with or | |
without HTTP. The server is closer to working without the HTTP | |
module, although there is still more to do. [Ryan Bloom] | |
*) Fix a number of SGI compile warnings throughout the server. Fix some | |
bad parameters to apr_bucket_read(). Fix a bad statement in | |
ap_method_in_list(). For the mod_rewrite cache use apr_time_t | |
consistently; we were mixing apr_time_t and time_t in invalid ways | |
before. In load_file(), call apr_dso_error() instead of | |
apr_strerror() so that we get a more specific string on some platforms. | |
PR #6980 [Jeff Trawick] | |
*) Allow modules to query the MPM about it's execution profile. This | |
query API can and should be extended in the future, but for now, | |
max_daemons, and threading or forking is a very good start. | |
[Jon Travis <jtravis covalent.net>] | |
*) Modify mod_include to send blocks of data no larger than 9k. | |
Without this, mod_include will wait until the whole file is parsed, | |
or the first tag is found to send any data to the client. | |
[Paul J. Reder <rederpj raleigh.ibm.com>] | |
*) Fix mod_info, so that <Directory> and <Location> directives are | |
not displayed twice when displaying the current configuration. | |
[Ryan Morgan <rmorgan covalent.net>] | |
*) Add config directives to override DEFAULT_ERROR_MSG and | |
DEFAULT_TIME_FORMAT. This was sent in as PR 6193. | |
[Dan Rench <drench xnet.com>] | |
*) Get mod_info building and loading on Win32. [William Rowe] | |
*) Begin to move protocol independant functions out of mod_http. The goal | |
is to have only functions that are HTTP specific in the http directory. | |
[Ryan Bloom] | |
Changes with Apache 2.0.13 | |
*) Don't assume that there will always be multiple calls to the byterange | |
filter. It is possible that we will need to do byteranges with only | |
one call to the filter. [Ryan Morgan <rmorgan covalent.net>] | |
*) Move the error_bucket definition from the http module to the | |
core server. Every protocol will need this ability, not just | |
HTTP. [Ryan Bloom] | |
Changes with Apache 2.0.12 | |
*) Modify mod_file_cache to save pre-formatted strings for | |
content-length and last-modified headers for performance. | |
[Mike Abbot <mja trudge.engr.sgi.com>] | |
*) Namespace protect IOBUFSIZ since it is exposed in the API. | |
[Jon Travis <jtravis covalent.net>] | |
*) Use "Basic" authentication instead of "basic" in ab, as the spec | |
says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>] | |
*) Fix a seg fault in mod_userdir.c. We used to use the pw structure | |
without ever filling it out. This fixes PR 7271. | |
[Taketo Kabe <kabe sra-tohoku.co.jp> and | |
Cliff Woolley <cliffwoolley yahoo.com>] | |
*) Add a couple of GCC attribute tags to printf style functions. | |
[Jon Travis <jtravis covalent.net>] | |
*) Add the correct language tag for interoperation with the Taiwanese | |
versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142 | |
*) Migrate the perchild MPM to use the new apr signal child, and | |
APR thread functions. [Ryan Bloom] | |
*) Close one copy of the CGI's stdout before creating the new process. | |
The CGI will still have stdout, because we have already dup'ed it. | |
This keeps Apache from waiting forever to send the results of a CGI | |
process that has forked a long-lived child process. | |
[Taketo Kabe <kabe sra-tohoku.co.jp>] | |
*) Remove the rest of the pthreads functions from the threaded MPM. | |
This requires the APR support for a signal thread that was just | |
added. [Ryan Bloom] | |
*) Make mod_dir use a fixup for sending a redirect to the browser. | |
Before this, we were using a handler, which doesn't make much | |
sense, because the handler wasn't generating any data, it would | |
either return a redirect error code, or DECLINED. This fits the | |
current hooks better. [Ryan Morgan <rmorgan covalent.net>] | |
*) Make the threaded MPM use APR threads instead of pthreads. | |
[Ryan Bloom] | |
*) Get mod_tls to the point where it actually appears to work in all cases. | |
[Ben Laurie] | |
*) implement --enable-modules and --enable-mods-shared for "all" and | |
"most". [Greg Stein] | |
*) Move the threaded MPM to use APR locks instead of pthread locks. | |
[Ryan Bloom] | |
*) Rename mpmt_pthread to threaded. This is more in line with the | |
fact that mpmt_pthread shouldn't be using pthreads directly, and | |
it is a smaller name that doesn't tie into anything. | |
[Ryan Bloom] | |
*) Rename the module structures so that the exported symbol matches | |
the file name, and it is easier to automate the installation | |
process (generating LoadModule directives from the module filenames). | |
[Martin Kraemer] | |
*) Remove the coalesce filter. With the ap_f* functions, this filter | |
is no longer needed. [Ryan Bloom] | |
Changes with Apache 2.0.11 | |
*) Remove the dexter MPM. Perchild is the same basic idea, but it has the | |
added feature of allowing a uid/gid per child process. If no | |
uid/gid is specified, then Perchild behaves exactly like dexter. | |
[Ryan Bloom] | |
*) Get perchild building again. [Ryan Bloom] | |
*) Don't disable threads just because we are using the prefork MPM. | |
If somebody wants to compile without threads, they must now add | |
--disable-threads to the configure command line. [Ryan Bloom] | |
*) Begin to move the calls to update_child_status into common code, so | |
that each individual MPM does not need to update the scoreboard itself. | |
[Ryan Bloom] | |
*) Allow mod_tls to compile under Unix boxes where openssl has been | |
installed to the system include files. | |
[Gomez Henri <new-httpd slib.fr>] | |
*) Cleanup the mod_tls configure process. This should remove any need | |
to hand-edit any files. We require OpenSSL 0.9.6 or later, but | |
configure doesn't check that yet. [Ryan Bloom] | |
*) Add a very early prototype of SSL support (in mod_tls.c). It is | |
vital that you read modules/tls/README before attempting to build | |
it. [Ben Laurie] | |
*) Fix a potential seg fault on all platforms. David Reid fixed this | |
on BEOS, but the problem could happen anywhere, so we don't want | |
to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>] | |
*) Add new LogFormat directive, %D, to log time it takes to serve a | |
request in microseconds. [Bill Stoddard] | |
*) Change AddInputFilter and AddOutputFilter to SetInputFilter and | |
SetOutputFilter. This corresponds nicely with the other Set | |
directives, which operate on containers while the Add* directives | |
tend to work directly on extensions. [Ryan Bloom] | |
*) Cleanup the header handling a bit. This uses the apr_brigade_* | |
functions for the buffering so that we don't need to compute | |
the length of the headers before we actually create the header | |
buffer. [Ryan Bloom] | |
*) Allow filters to buffer data using the ap_f* functions. These have | |
become macros that resolve directly to apr_brigade_*. | |
[Ryan Bloom] | |
*) Get the Unix MPM's to do a graceful restart again. If we are going | |
to register a cleanup with ap_cleanup_scoreboard, then we have to | |
kill the cleanup with the same function, and that function can't be | |
static. [Ryan Bloom] | |
*) Install all required header files. Without these, it was not | |
possible to compile some modules outside of the server. | |
[Ryan Bloom] | |
*) Fix the AliasMatch directive in Apache 2.0. When we brought a patch | |
forward from 1.3 to 2.0, we missed a single line, which broke regex | |
aliases. [Ryan Bloom] | |
*) We have a poor abstraction in the protocol. This is a temporary | |
hack to fix the bug, but it will need to be fixed for real. If | |
we find an error while sending out a custom error response, we back | |
up to the first non-OK request and send the data. Then, when we send | |
the EOS from finalize_request_protocol, we go to the last request, | |
to ensure that we aren't sending an EOS to a request that has already | |
received one. Because the data is sent on a different request than | |
the EOS, the error text never gets sent down the filter stack. This | |
fixes the problem by finding the last request, and sending the data | |
with that request. [Ryan Bloom] | |
*) Make the server status page show the correct restart time, and | |
thus the proper uptime. [Ryan Bloom] | |
*) Move the CGI creation logic from mod_include to mod_cgi(d). This | |
should reduce the amount of duplicate code that is required to | |
create CGI processes. | |
[Paul J. Reder <rederpj raleigh.ibm.com>] | |
*) ap_new_connection() closes the socket and returns NULL if a socket | |
call fails. Usually this is due to a connection which has been | |
reset. [Jeff Trawick] | |
*) Move the Apache version information out of httpd.h and into release.h. | |
This is in preparation for the first tag with the new tag and release | |
system. [Ryan Bloom] | |
*) Begin restructuring scoreboard code to enable adding back in | |
the ability to use IPC other than shared memory. | |
Get mod_status working on Windows again. [Bill Stoddard] | |
*) Make mod_status work with 2.0. This will work for prefork, | |
mpmt_pthread, and dexter. [Ryan Bloom] | |
*) Correct a typo in httpd.conf. | |
[Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154 | |
*) Really fix mod_rewrite map lookups this time. [Tony Finch] | |
*) Get the correct IP address if ServerName isn't set and we can't | |
find a fully-qualified domain name at startup. | |
PR#7170 [Danek Duvall <dduvall eng.sun.com>] | |
*) Make mod_cgid work with SuExec. [Ryan Bloom] | |
*) Adopt apr user/group name features for mod_rewrite. Eliminates some | |
'extra' stat's for user/group since they should never occur, and now | |
resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS | |
volumes. [William Rowe] | |
*) Adopt apr features to simplify mod_includes. This changes the | |
behavior of the USER_NAME variable, unknown uid's are now reported | |
as USER_NAME="<unknown>" rather than the old user#000 result. | |
WinNT now resolves USER_NAME on NTFS volumes. [William Rowe] | |
*) Adopt apr features for simplifing mod_userdir, and accept the new | |
Win32/OS2 exceptions without hiccuping. [William Rowe] | |
*) Replace configure --with-optim option by using and saving the | |
environment variable OPTIM instead. This is needed because configure | |
options do not support multiple flags separated by spaces. | |
[Roy Fielding] | |
*) Fix some byterange handling. If we get a byte range that looks like | |
"-999999" where that is past the end of the file, we should return | |
a PARTIAL CONTENT status code, and return the whole file as one big | |
byterange. This matches the 1.3 handling now. [Ryan Bloom] | |
*) Make the error bucket a real meta-data bucket. This means that the | |
bucket length is 0, and a read returns NULL data. If one of these | |
buckets is passed down after the headers are sent, this data will | |
just be ignored. [Greg Stein] | |
*) The prefork MPM wasn't killing child processes correctly if a restart | |
signal was received while the process was serving a request. The child | |
process would become the equivalent of a second parent process. If | |
we break out of the accept loop, then we need to do die after cleaning | |
up after ourselves. [Ryan Bloom] | |
*) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful | |
restarts. [Ryan Bloom] | |
*) Modify the apr_stat/lstat/getfileinfo calls within apache to use | |
the most optimal APR_FINFO_wanted bits. This spares Win32 from | |
performing very expensive owner, group and permission lookups | |
and allows the server to function until these apr_finfo_t fields | |
are implemented under Win32. [William Rowe] | |
*) Support for typedsafe optional functions - that is functions exported by | |
optional modules, which, therefore, may or may not be present, depending | |
on configuration. See the experimental modules mod_optional_fn_{ex,im}port | |
for sample code. [Ben Laurie] | |
*) filters can now report an HTTP error to the server. This is done | |
by sending a brigade where the first bucket is an error_bucket. | |
This bucket is a simple bucket that stores an HTTP error and | |
a string. Currently the string is not used, but it may be needed | |
to output an error log. The http_header_filter will find this | |
bucket, and output the error text, and then return | |
AP_FILTER_ERROR, which informs the server that the error web page | |
has already been sent. [Ryan Bloom] | |
*) If we get an error, then we should remove all filters except for | |
those critical to serving a web page. This fixes a bug, where | |
error pages were going through the byterange filter, even though | |
that made no sense. [Ryan Bloom] | |
*) Relax the syntax checking of Host: headers in order to support | |
iDNS. PR#6635 [Tony Finch] | |
*) Cleanup the byterange filter to use the apr_brigade_partition | |
and apr_bucket_copy functions. This removes a lot of very messy | |
code, and hopefully makes this filter more stable. | |
[Ryan Bloom] | |
*) Remove AddModule and ClearModuleList directives. Both of these | |
directives were used to ensure that modules could be enabled | |
in the correct order. That requirement is now gone, because | |
we use hooks to ensure that modules are in the correct order. | |
[Ryan Bloom] | |
*) When SuExec is specified, we need to add it to the list of | |
targets to be built. If we don't, then any changes to the | |
configuration won't affect SuExec, unless 'make suexec' is | |
specifically run. [Ryan Bloom] | |
*) Cleaned out open_file from mod_file_cache, as apr now accepts | |
the APR_XTHREAD argument to open a file for consumption by | |
parallel threads on win32. [William Rowe] | |
*) Correct a bug in determining when we follow symlinks. The code | |
expected a stat -1 result, not an apr_status_t positive error. | |
Also check if the APR_FINFO_USER fields are valid before we | |
follow the link. [William Rowe] | |
*) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to | |
mpm_common.c. These functions are only valid on some platforms, | |
so they should not be in the main-line code. [Ryan Bloom] | |
*) Remove ap_chdir_file(). This function is not thread-safe, | |
and nobody is currently using it. [Ryan Bloom] | |
*) Do not try to run make depend if there are no .c files in the | |
current directory, doing so makes `make depend` fail. | |
[Ryan Bloom] | |
*) Update highperformance.conf to work with either prefork or | |
pthreads mpms. [Greg Ames] | |
*) Stop checking to see if this is a pipelined request if we know | |
for a fact that it isn't. Basically, if r->connection->keepalive == 0. | |
This keeps us from making an extra read call when serving a 1.0 | |
request. [Ryan Bloom and Greg Stein] | |
*) Fix the handling of variable expansion look-ahead in mod_rewrite, | |
i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of | |
more complicated nested RewriteMap lookups. PR#7087 [Tony Finch] | |
*) Fix the RFC number mentioned when complaining about a missing | |
Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>] | |
*) Fix an endless loop in ab which occurred when ab was posting | |
and the server dropped the connection unexpectedly. | |
[Jeff Trawick] | |
*) Fix a segfault while handling request bodies in ap_http_filter(). | |
This problem has been seen with mod_dav usage as well as with | |
requests where the body was just being discarded. [Jeff Trawick] | |
*) Some adjustment on the handling and automatic setting (via | |
hints.m4) of various compilation flags (eg: CFLAGS). Also, | |
add the capability to specify flags (NOTEST_CFLAGS and | |
NOTEST_LDFLAGS) which are used to compile Apache, but | |
not used during the configuration process. Useful for | |
flags like "-Werror". [Jim Jagielski] | |
*) Stop using environment variables to force debug mode or | |
no detach. We now use the -D command line argument to | |
specify the correct mode. -DONE_PROCESS and -DNO_DETACH. | |
[Greg Stein, Ryan Bloom] | |
*) Change handlers to use hooks. [Ben Laurie] | |
*) Stop returning copies of filenames from both apr_file_t and | |
apr_dir_t. We pstrdup the filenames that we store in the | |
actual structures, so we don't need to pstrdup the strings again. | |
[Ryan Bloom] | |
*) mod_cgi: Fix some problems where the wrong error value was being | |
traced. [Jeff Trawick] | |
*) EBCDIC: Fix some missing ASCII conversion on some protocol data. | |
[Jeff Trawick] | |
*) Add generic hooks. [Ben Laurie] | |
*) Use a real pool to dup the error log descriptor. [Ryan Bloom] | |
*) Fix a segfault caused by mod_ext_filter when the external filter | |
program does not exist. [Jeff Trawick] | |
*) Fix an output truncation error when on an HTTP >= 1.0 request an | |
object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE | |
was served through mod_charset_lite (or anything else that would | |
create a transient bucket in this size range). ap_bucket_make_heap() | |
silently failed (fixed), transient_setaside() discovered it, but | |
ap_save_brigade() ignored it (fixed). [Jeff Trawick] | |
*) Ignore \r\n or \n when using PEEK mode for input filters. The problem | |
is that some browsers send extra lines at the end of POST requests, and | |
we don't want to delay sending data back to the user just because the | |
browser isn't well behaved. [Ryan Bloom] | |
*) Get SuEXEC working again. We can't send absolute paths to suExec | |
because it refuses to execute those programs. SuEXEC also wasn't | |
always recognizing configuration changes made using the autoconf | |
setup. [Ryan Bloom] | |
*) Allow the buildconf process to find the config.m4 files in the correct | |
order. Basically, we can now name config.m4 files as config\d\d.m4, | |
and we will sort them correctly when inserting them into the build | |
process. [Ryan Bloom] | |
*) Get mod_cgid to use apr calls for creating the actual CGI process. | |
This also allows mod_cgid to use ap_os_create_priviledged_process, | |
thus allowing for SuExec execution from mod_cgid. Currently, we do | |
not support everything that standard SuExec supports, but at least | |
it works minimally now. [Ryan Bloom] | |
*) Allow SuExec to be configured from the ./configure command line. | |
[Ryan Bloom] | |
*) Update some of the docs in README and INSTALL to reflect some of | |
the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>] | |
*) If we get EAGAIN returned from the call to apr_sendfile, then we | |
need to call sendfile again. This gets us serving large files | |
such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom] | |
*) Get the support programs building cleanly again. | |
[Cliff Woolley <cliffwoolley yahoo.com>] | |
*) The Apache/Win32 Apache.exe and dll's now live in bin. The | |
current directory logic now backs up over bin/ to determine the | |
server root from the Apache.exe path. | |
*) Apache/Win32 now follows the standard conventions of mod_foo.so | |
loadable modules, dynamic libs are all named libfoo.dll, and the | |
makefile.win populates the include, lib and libexec directories. | |
*) Apache is now IPv6-capable. On systems where APR supports IPv6, | |
Apache gets IPv6 listening sockets by default. Additionally, the | |
Listen, NameVirtualHost, and <VirtualHost> directives support IPv6 | |
numeric address strings (e.g., "Listen [fe80::1]:8080"). | |
[Jeff Trawick] | |
*) Modify the install directory layout. Modules are now installed in | |
modules/. Shared libraries should be installed in libraries/, but | |
we don't have any of those on Unix yet. All install directories | |
are modifyable at configure time. [Ryan Bloom] | |
*) Install all header files in the same directory on Unix. [Ryan Bloom] | |
*) Get the functions in server/linked into the server, regardless of | |
which modules linked into the server. This uses the same hack | |
for Apache that we use for APR and apr-util to ensure all of the | |
necessary functions are linked. As a part of thise, the CHARSET_EBCDIC | |
was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make | |
the scripts a bit easier. | |
[Ryan Bloom] | |
*) Rework the RFC1413 handling to make it thread-safe, use a timeout | |
on the query, and remove IPv4 dependencies. [Jeff Trawick] | |
*) Get all of the auth modules to the point that they will install and | |
be loadable into the server. Our new build/install mechanism expects | |
that all modules will have a common name format. The auth modules | |
didn't use that format, so we didn't install them properly. | |
[Ryan Bloom] | |
*) API routines ap_pgethostbyname() and ap_pduphostent() are no longer | |
available. Use apr_getaddrinfo() instead. [Jeff Trawick] | |
*) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom] | |
*) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts | |
after the end of the response. [Ryan Bloom] | |
*) Get byterange requests working with responses that do not have a | |
content-length. Because of the way byterange requests work, we have to | |
have all of the data before we can actually do the byterange, so we | |
can compute the content-length in the byterange filter. | |
[Ryan Bloom] | |
*) Get exe CGI's working again on Windows. | |
[Allan Edwards] | |
*) Get mod_cgid and mod_rewrite to work as DSOs by changing the way | |
they keep track of whether or not their post config hook has been | |
called before. Instead of a static variable (which is replaced when | |
the DSO is loaded a second time), use userdata in the process pool. | |
[Jeff Trawick] | |
Changes with Apache 2.0a9 | |
*) Win32 now requires perl to complete the final install step for users | |
to build + install on Win32. Makefile.win now rewrites @@ServerRoot@ | |
and installs the conf, htdocs and htdocs/manual directories. | |
[William Rowe] | |
*) Make mod_include use a hash table to associate directive tags with | |
functions. This allows modules to implement their own SSI tags easily. | |
The idea is simple enough, a module can insert it's own tag and function | |
combination into a hash table provided by mod_include. While mod_include | |
parses an SSI file, when it encounters a tag in the file, it does a | |
hash lookup to find the function that implements that tag, and passes | |
all of the relevant data to the function. That function is then | |
responsible for processing the tag and handing the remaining data back | |
to mod_include for further processing. | |
[Paul J. Reder <rederpj raleigh.ibm.com>] | |
*) Get rid of ap_new_apr_connection(). ap_new_connection() now has | |
fewer parameters: the local and remote socket addresses were removed | |
from the parameter list because all required information is available | |
via the APR socket. [Jeff Trawick] | |
*) Distribution directory structure reorganized to reflect a | |
normal source distribution with external install targets. | |
[Roy Fielding] | |
*) The MPMs that need multiple segments of shared memory now create | |
two apr_shmem_t variables, one for each shared memory allocation. | |
the problem is that we can't determine how much memory will be required | |
for shared memory allocations once we try to allocate more than one | |
variable. The MM code automatically aligns the shared memory allocations, | |
so we end up needing to pad the amount of shared memory we want based | |
on how many variables will be allocated out of the shared memory segment. | |
It is just easier to create a second apr_shmem_t variable, and two | |
shmem memory blocks. | |
[Ryan Bloom] | |
*) Cleanup the export list a bit. This creates a single unified list of | |
functions exported by APR. The export list is generated at configure | |
time, and that list is then used to generate the exports.c file. | |
Because of the way the export list is generated, we only export those | |
functions that are valid on the platform we are building on. | |
[Ryan Bloom] | |
*) Enable logging the cookie with mod_log_config | |
[Sander van Zoest <sander covalent.net>] | |
*) Fix a segfault in mod_info when it reaches the end of the configuration. | |
[Jeff Trawick] | |
*) Added lib/aputil/ as a placeholder for utility functions which are not | |
specific to the Apache HTTP Server (but do not make sense with APR). | |
The first utility is "apu_dbm": a set of functions to work with DBM | |
files. This first version can be compiled for SDBM or GDBM databases. | |
[Greg Stein] | |
*) Complete re-write of mod_include. This makes mod_include a filter that | |
uses buckets directly. This has now served the FAQ correctly. | |
[Paul Reder <rederpj raleigh.ibm.com>] | |
*) Allow modules to specify the first filter in a sub_request when | |
making the sub_request. This keeps modules from having to change the | |
output_filter immediately after creating the sub-request, and therefore | |
skip the sub_req_output_filter. [Ryan Bloom] | |
*) Update ab to accept URLs with IPv6 literal address strings (in the | |
format described in RFC 2732), and to build Host header fields in | |
the same format. This allows IPv6 literal address strings to be | |
used with ab. This support has been tested against Apache 1.3 with | |
the KAME patch, but Apache 2.0 does not yet work with this format | |
of the Host header field. [Jeff Trawick] | |
*) Accomodate an out-of-space condition in the piped logs and the | |
rotatelogs.c code, and no longer churn log processes for this | |
condition. [Victor J. Orlikowski] | |
*) Add support for partial writes with apr_sendfile() to core_output_filter. | |
[Greg Ames] | |
Changes with Apache 2.0a8 | |
*) Add a directive to mod_mime so that filters can be associated with | |
a given mime-type. | |
[Ryan Bloom] | |
*) Get multi-views working again. We were setting the path_info | |
field incorrectly if we couldn't find the specified file. | |
[Ryan Bloom] | |
*) Fix 304 processing. The core should never try to send the headers | |
down the filter stack. Always, just setup the table in the request | |
record, and let the header filter convert it to data that is ready | |
for the network. | |
[Ryan Bloom] | |
*) More fixes for the proxy. There are still bugs in the proxy code, | |
but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP) | |
successfully. | |
[Ryan Bloom] | |
*) Fix params for apr_getaddrinfo() call in connect proxy handler. | |
[Chuck Murcko] | |
*) APR: Add new apr_getopt_long function to handle long options. | |
[B. W. Fitzpatrick <fitz red-bean.com>] | |
*) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname. | |
Add generic apr_create_socket(). Add apr_getaddrinfo() for doing | |
hostname resolution/address string parsing and building | |
apr_sockaddr_t. Add apr_get_sockaddr() for getting the address | |
of one of the apr_sockaddr_t structures for a socket. Change | |
apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick] | |
*) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but | |
I have proxied pages with it, cleanup will commence soon. | |
[Ryan Bloom] | |
*) Make the proxy work with filters. This isn't perfect, because we | |
aren't dealing with the headers properly. [Ryan Bloom] | |
*) Do not send a content-length iff the C-L is 0 and this is a head | |
request. [Ryan Bloom] | |
*) Make cgi-bin work as a regular directory when using mod_vhost_alias | |
with no VirtualScriptAlias directives. PR#6829 [Tony Finch] | |
*) Remove BUFF from the PROXY connect handling. [Ryan Bloom] | |
*) Get the default_handler to stop trying to deal with HEAD requests. | |
The idea is to let the content-length filter compute the C-L before | |
we try to send the data. If we can get the C-L correctly, then we | |
should send it in the HEAD response. | |
[Ryan Bloom] | |
*) The Header filter can now determine if a body should be sent based | |
on r->header_only. The general idea of this is that if we delay | |
deciding to send the body, then we might be able to compute the | |
content-length correctly, which will help caching proxies to cache | |
our data better. Any handler that doesn't want to try to compute | |
the content-length can just send an EOS bucket without data and | |
everything will just work. | |
[Ryan Bloom] | |
*) Add the referer to the error log if one is available. | |
[Markus Gyger <mgyger itr.ch>] | |
*) Mod_info.c has now been ported to Apache 2.0. As a part of this | |
change, the root of the configuration tree has been exposed to modules | |
as ap_conftree. | |
[Ryan Morgan <rmorgan covalent.net>] | |
*) Get the core_output_filter to use the bucket interface directly. | |
This keeps us from calling the content-length filter multiple times | |
for a simple static request. | |
[Ryan Bloom] | |
*) We are sending the content-type correctly now. | |
[Ryan Bloom and Will Rowe] | |
*) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report | |
a bogus bytes-sent value when the only thing being sent was trailers | |
and writev() returned an error (or EAGAIN). [Jeff Trawick] | |
*) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the | |
hints file to determine which platforms define | |
SINGLE_LISTEN_UNSERIALIZED_ACCEPT. | |
[Ryan Bloom] | |
*) APR: add apr_get_home_directory() [Jeff Trawick] | |
*) Initial import of 1.3-current mod_proxy. [Chuck Murcko] | |
*) Not all platforms have INADDR_NONE defined by default. Apache | |
used to make this check and define INADDR_NONE if appropriate, | |
but APR needs the check too, and I suspect other applications will | |
as well. APR now defines APR_INADDR_NONE, which is always a valid | |
value on all platforms. | |
[Branko Èibej <brane xbc.nu>] | |
*) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824. | |
[Shuichi Kitaguchi <ki hh.iij4u.or.jp>] | |
*) Relax the syntax checking of Host: headers in order to support | |
iDNS. PR#6635 [Tony Finch] | |
*) When reading from file buckets we convert to an MMAP if it makes | |
sense. This also simplifies the default handler because the | |
default handler no longer needs to try to create MMAPs. | |
[Ryan Bloom] | |
*) BUFF has been removed from the main server. The BUFF code will remain | |
in the code until it has been purged from the proxy module as well. | |
[Ryan Bloom] | |
*) Byteranges have been completely re-written to be a filter. This | |
has been tested, and I believe it is working correctly, but it could | |
doesn't work for the Adobe Acrobat plug-in. The output almost matches | |
the output from 1.3, the only difference being that 1.3 includes | |
a content-length in the response, and this does not. | |
[Ryan Bloom] | |
*) APR read/write functions and bucket read functions now operate | |
on unsigned integers, instead of signed ones. It doesn't make | |
any sense to use signed ints, because we return the error codes, | |
so if we have an error we should report 0 bytes read or written. | |
[Ryan Bloom] | |
*) Always compute the content length, whether it is sent or not. | |
The reason for this, is that it allows us to correctly report | |
the bytes_sent when logging the request. This also simplifies | |
content-length filter a bit, and fixes the actual byte-reporing | |
code in mod_log_config.c | |
[Ryan Bloom] | |
*) Remove AP_END_OF_BRIGADE definition. This does not signify what | |
it says, because it was only used by EOS and FLUSH buckets. Since | |
neither of those are required at the end of a brigade, this was | |
really signifying FLUSH_THE_DATA, but that can be determined better | |
by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH | |
buckets now return a length of 0, which is actually the amount of data | |
read, so they make more sense. | |
[Ryan Bloom] | |
*) Allow the core_output_filter to save some data past the end of a | |
request. If we get an EOS bucket, we only send the data if it | |
makes sense to send it. This allows us to pipeline request | |
responses. As a part of this, we also need to allocate mmap | |
buckets out of the connection pool, not the request pool. This | |
allows the mmap to outlive the request. | |
[Ryan Bloom] | |
*) Make blocking and non-blocking bucket reads work correctly for | |
sockets and pipes. These are the only bucket types that should | |
have non-blocking reads, because the other bucket types should | |
ALWAYS be able to return something immediately. | |
[Ryan Bloom] | |
*) In the Apache/Win32 console window, accept Ctrl+C to stop the | |
server, but use Ctrl+Break to initiate a graceful restart | |
instead of duplicating behavior. [John Sterling] | |
*) Patch mod_autoindex to set the Last-Modified header based on | |
the directory's mtime, and add the ETag header. [William Rowe] | |
*) Merge the 1.3 patch to add support for logging query string in | |
such a way that "%m %U%q %H" is the same as "%r". | |
[Bill Stoddard] | |
*) Port three log methods from mod_log_config 1.3 to 2.0: | |
CLF compliant '-' byte count, method and protocol. | |
[Bill Stoddard] | |
*) Add a new LogFormat directive, %c, that will log connection | |
status at the end of the response as follows: | |
'X' - connection aborted before the response completed. | |
'+' - connection may be kept-alive by the server. | |
'-' - connection will be closed by the server. | |
[Bill Stoddard] | |
*) Expand APR for WinNT to fully accept and return utf-8 encoded | |
Unicode file names and paths for Win32, and tag the Content-Type | |
from mod_autoindex to reflect that charset if the the feature | |
macro APR_HAS_UNICODE_FS is true. [William Rowe] | |
*) Compute the content length (and add appropriate header field) for | |
the response when no content length is available and we can't use | |
chunked encoding. [Jeff Trawick] | |
*) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK, | |
so that content input filters get dechunked data when using | |
the default handler. Also removed REQUEST_CHUNKED_PASS. | |
[Sascha Schumann] | |
*) Add mod_ext_filter as an experimental module. This module allows | |
the administrator to use external programs as filters. Currently, | |
only filtering of output is supported. [Jeff Trawick] | |
*) Most Apache functions work on EBCDIC machines again, as protocol | |
data is now translated (again). [Jeff Trawick] | |
*) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of | |
the EBCDIC support. They are noops on ASCII machines, so this | |
type of translation doesn't have to be surrounded by #ifdef | |
CHARSET_EBCDIC. [Jeff Trawick] | |
*) Fix mod_include. tag commands work again, and the server will | |
send the FAQ again. This also allows mod_include to set aside | |
buckets that include partial buckets. | |
[Ryan Bloom and David Reid] | |
*) Add suexec support back. [Manoj Kasichainula] | |
*) Lingering close now uses the socket directly instead of using | |
BUFF. This has been tested, but since all we can tell is that it | |
doesn't fail, this needs to be really hacked on. | |
[Ryan Bloom] | |
*) Allow filters to modify headers and have those headers be sent to | |
the client. The idea is that we have an http_header filter that | |
actually sends the headers to the network. This removes the need | |
for the BUFF to send headers. | |
[Ryan Bloom] | |
*) Charset translation: mod_charset_lite handles translation of | |
request bodies. Get rid of the xlate version of ap_md5_digest() | |
since we don't compute digests of filtered (e.g., translated) | |
response bodies this way anymore. (Note that we don't do it at | |
all at the present; somebody needs to write a filter to do so.) | |
[Jeff Trawick] | |
*) Input filters and ap_get_brigade() now have a input mode parameter | |
(blocking, non-blocking, peek) instead of a length parameter. | |
[hackathon] | |
*) Update the mime.types file to the registered media types as | |
of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>, | |
Tony Finch] | |
*) Namespace protect some macros declared in ap_config.h | |
[Ryan Bloom] | |
*) Support HTTP header line folding with input filtering. | |
[Greg Ames] | |
*) Mod_include works again. This should still be re-written, but at | |
least now we can serve an SHTML page again. | |
[Ryan Bloom] | |
*) Begin to remove BUFF from the core. Currently, we keep a pointer | |
to both the BUFF and the socket in the conn_rec. Functions that | |
want to use the BUFF can, functions that want to use the socket, | |
can. They point to the same place. | |
[Ryan Bloom] | |
*) apr_psprintf doesn't understand %lld as a format. Make it %ld. | |
[Tomas "Ögren" <stric ing.umu.se>] | |
*) APR pipes on Unix and Win32 are now cleaned up automatically when the | |
associated pool goes away. (APR pipes on OS/2 were already had this | |
logic.) This resolvs a fatal file descriptor leak with CGIs. | |
[Jeff Trawick] | |
*) The final line of the config file was not being read if there was | |
no \n at the end of it. This was caused by apr_fgets returning | |
APR_EOF even though we had read valid data. This is solved by | |
making cfg_getline check the buff that was returned from apr_fgets. | |
If apr_fgets return APR_EOF, but there was data in the buf, then we | |
return the buf, otherwise we return NULL. | |
[Ryan Bloom] | |
*) Piped logs work again in the 2.0 series. | |
[Ryan Bloom] | |
*) Restore functionality broken by the mod_rewrite security fix: | |
rewrite map lookup keys and default values are now expanded | |
so that the lookup can depend on the requested URI etc. | |
PR #6671 [Tony Finch] | |
*) SECURITY: Tighten up the syntax checking of Host: headers to fix a | |
security bug in some mass virtual hosting configurations | |
that can allow a remote attacker to retrieve some files | |
on the system that should be inaccessible. [Tony Finch] | |
*) Add a pool bucket type. This bucket is used for data allocated out | |
of a pool. If the pool is cleaned before the bucket is destroyed, then | |
the data is converted to a heap bucket, allowing it to survive the | |
death of the pool. | |
[Ryan Bloom] | |
*) Add a flush bucket. This allows modules to signal that the filters | |
should all flush whatever data they currently have. There is no way | |
to actually force them to do this, so if a filter ignores this bucket, | |
that's life, but at least we can try with this. | |
[Ryan Bloom] | |
*) Add an output filter for sub-requests. This filter just strips the | |
EOS bucket so that we don't confuse the main request's core output | |
filter by sending multiple EOS buckets. This change also makes sub | |
requests start to send EOS buckets when they are finished. | |
[Ryan Bloom] | |
*) Make ap_bucket_(read|destroy|split|setaside) into macros. Also | |
makes ap_bucket_destroy a return void, which is okay because it | |
used to always return APR_SUCCESS, and nobody ever checked its | |
return value anyway. | |
[Cliff Woolley <cliffwoolley yahoo.com>] | |
*) Remove the index into the bucket-type table from the buckets | |
structure. This has now been replaced with a pointer to the | |
bucket_type. Also add some macros to test the bucket-type. | |
[Ryan Bloom] | |
*) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols | |
for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper) | |
and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE. | |
All _VAR_ flavors changes to _DATA to be absolutely clear. | |
[William Rowe] | |
*) Add support for /, //, //servername and //server/sharename | |
parsing of <Directory> blocks under Win32 and OS2. | |
[Tim Costello, William Rowe, Brian Harvard] | |
*) Remove the function pointers from the ap_bucket type. They have been | |
replaced with a global table. Modules are allowed to register bucket | |
types and use then use those buckets. | |
[Ryan Bloom] | |
*) mod_cgid: In the handler, shut down the Unix socket (only for write) | |
once we finish writing the request body to the cgi child process; | |
otherwise, the client doesn't hit EOF on stdin. Small request bodies | |
worked without this change (for reasons I don't understand), but large | |
ones didn't. [Jeff Trawick] | |
*) Remove file bucket specific information from the ap_bucket type. | |
This has been moved to a file_bucket specific type that hangs off | |
the data pointer in the ap_bucket type. | |
[Ryan Bloom] | |
*) Input filtering now has a third argument. This is the amount of data | |
to read from lower filters. This argument can be -1, 0, or a positive | |
number. -1 means give me all the data you have, I'll deal with it and | |
let you know if I need more. 0 means give me one line and one line | |
only. A positive number means I want no more than this much data. | |
Currently, only 0 and a positive number are implemented. This allows | |
us to remove the remaining field from the conn_rec structure, which | |
has also been done. | |
[Ryan Bloom] | |
*) Big cleanup of the input filtering. The goal is that http_filter | |
understands two conditions, headers and body. It knows where it is | |
based on c->remaining. If c->remaining is 0, then we are in headers, | |
and http_filter returns a line at a time. If it is not 0, then we are | |
in body, and http_filter returns raw data, but only up to c->remaining | |
bytes. It can return less, but never more. | |
[Greg Ames, Ryan Bloom, Jeff Trawick] | |
*) mod_cgi: Write all of the request body to the child, not just what | |
the kernel would accept on the first write. [Jeff Trawick] | |
*) Back out the change that moved the brigade from the core_output_filters | |
ctx to the conn_rec. Since all requests over a given connection | |
go through the same core_output_filter, the ctx pointer has the | |
correct lifetime. | |
[Ryan Bloom] | |
*) Fix another bug in the send_the_file() read/write loop. A partial | |
send by apr_send would cause unsent data in the read buffer to | |
get clobbered. Complete making send_the_file handle partial | |
writes to the network. | |
[Bill Stoddard] | |
*) Fix a couple of type fixes to allow compilation on AIX again | |
[Victor J. Orlikowski <v.j.orlikowski gte.net>] | |
*) Fix bug in send_the_file() which causes offset to be ignored | |
if there are no headers to send. | |
[Bill Stoddard] | |
*) Handle APR_ENOTIMPL returned from apr_sendfile in the core | |
filter. Useful for supporting Windows 9* with a binary | |
compiled on Windows NT. | |
[Bill Stoddard] | |
Changes with Apache 2.0a7 | |
*) Reimplement core_output_filter to buffer/save bucket brigades | |
across multiple calls to the core_filter. The brigade will be | |
sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE | |
thresholds are hit or the EOS bucket is received. | |
[Bill Stoddard] | |
*) Create experimental filter (buffer_filter) that coalesces bytes | |
into one large buffer before invoking the next filter in the | |
chain. This filter is particularly useful with the current | |
implementation of mod_autoindex when it inserted above the | |
chunk_filter. mod_autoindex generates a lot of brigades that | |
containing buckets holding just a few bytes each. The | |
buffer_filter coalesces these buckets into a single large bucket. | |
[Bill Stoddard] | |
*) Add apr_sendfile() support into the core_output_filter. | |
[Bill Stoddard] | |
*) Add apr_sendv() support into the core_output_filter. | |
[Bill Stoddard] | |
*) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS | |
[Mike Abbott <mja sgi.com>] | |
*) Remove ap_send_fb. This is no longer used in Apache, and it doesn't | |
make much sense, because Apache uses buckets instead of BUFFs now. | |
[Ryan Bloom] | |
*) send_the_file now falls back to a read/write loop on platforms that | |
do not have sendfile. | |
[Ryan Bloom and Brian Havard] | |
*) Install apachectl correctly, and substitute the proper values so | |
that it works again. [Ryan Bloom] | |
*) Better(??) handle platforms that lack sendfile(). | |
[Jim Jagielski] | |
*) APR now has UUID generation/formatting/parsing support. | |
[Greg Stein] | |
*) Begin the http_filter. This is an input filter that understands | |
the absolute basic amount required to parse an HTTP Request. The | |
goal is to be able to split headers from request body before passing | |
the data back to the other filters. | |
[Ryan Bloom] | |
*) Bring forward from 1.3.13 the config directory implementation | |
[Jim Jagielski] | |
*) install apxs if it is created | |
[Ryan Bloom] | |
*) Added APR_IS_STATUS_condition test macros to eliminate canonical error | |
conversions. [William Rowe] | |
*) Now that we have ap_add_input_filter(), rename ap_add_filter() to | |
ap_add_output_filter(). [Jeff Trawick] | |
*) Multiple build and configuration fixes | |
Build process: | |
-add datadir and localstatedir substitutions | |
-fix layout name | |
-fix logfilename misspelling | |
-fix evaluation of installation dir variables and | |
-replace $foobar by $(foobar) to be usefull in the makefile | |
Cross compile: | |
-add rules for cross-compiling in rules.mk. Okay, rule to check for | |
$CC_FOR_BUILD is still missing | |
-use CHECK_TOOL instead of CHECK_PROG for ranlib | |
-add missing "AR=@AR@" to severaly Makefile.in's | |
-cache result for "struct rlimit" | |
-compile all helper programs with native and cross compiler | |
and use the native version to generate header file | |
["Rüdiger" Kuhlmann <Tadu gmx.de>] | |
*) Prepare our autoconf setup for autoconf 2.14a and for cross- | |
compiling. | |
["Rüdiger" Kuhlmann <Tadu gmx.de>] | |
*) Fix a bug where a client which only sends \n to delimit header | |
lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED | |
message. Start working on ebcdic co-existance with input | |
filtering. | |
[William Rowe, Greg Ames] | |
*) If mod_so is enabled in the server always create libexec, even | |
if there are no modules installed in this directory. This is a | |
requirement for APXS to work correctly. | |
[Ryan Bloom] | |
*) Connection oriented output filters are now stored in the | |
conn_rec instead of the request_rec. This allows us to add the | |
output filter in the pre-connection phase instead of the | |
post_read_request phase, which keeps us from trying to write an | |
error page before we have a filter to write to the network. | |
[Ryan Bloom, Jeff Trawick, and Greg Ames] | |
*) Cleaning up an mmap bucket no longer deletes the mmap. An | |
mmap can be used across multiple buckets (default_handler with | |
byte ranges, mod_file_cache, mod_mmap_static), so cleanup of | |
the mmap itself can't be associated with the bucket. | |
[Jeff Trawick] | |
*) Add .dll caching directive ISAPICacheFile to mod_isapi. | |
[William Rowe] | |
*) Radical surgery to improve mod_isapi support under Win32. | |
Includes a number of newer ServerSupportFunction calls, support | |
for ReadClient (in order to retrieve POSTs greater than 48KB), | |
and general bug fixes to more reliably load ISAPI .dll's and | |
prevent leaking handle resources. Note: There are still | |
discrepancies between IIS's and Apache's ServerVariables, and | |
async calls are still not supported. Additional warnings are | |
logged to facilitate debugging of unsupported ISAPI calls. | |
[William Rowe] | |
*) Add input filtering to Apache. The basic idea for the input | |
filters is the same as the ideas for output filters. The biggest | |
difference is that instead of calling ap_pass_brigade, ap_get_brigade | |
should be called, and the order of execution for the filter itself is | |
different. When writing an output filter, a brigade is passed in, | |
and filters operate directly on that brigade, when done, they call | |
ap_pass_brigade. Input filters are the exact opposite. Because input | |
is not a push operation, filters first call ap_get_brigade. When this | |
function returns, the input filter will be left with a valid brigade. | |
The input filter should then operate on the brigade, and return. | |
[Ryan Bloom] | |
*) Fix building on BSD/OS using its native make. The build system | |
falls back to the BSD .include directive on that host platform. | |
[Sascha Schumann] | |
*) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5, | |
SHA1 and plaintext password encodings. Make feature tests a | |
bit more flexible. [William Rowe] | |
*) Charset translation: mod_charset_lite handles output content | |
translation in a filter. mod_charset_lite no longer ignores | |
subrequests. A bunch of cruft related to BUFF's support for | |
translating request and response bodies was removed. | |
[Jeff Trawick] | |
*) Move the addition of the CORE filter to the post_read_request | |
hook in http_core.c. This removes the need to add the filter in | |
multiple places and allows for an SSL module to be added much | |
simpler. [Ryan Bloom] | |
*) SECURITY [CVE-2000-0913] (cve.mitre.org): | |
Fix a security problem that affects certain configurations of | |
mod_rewrite. If the result of a RewriteRule is a filename that | |
contains expansion specifiers, especially regexp backreferences | |
$0..$9 and %0..%9, then it may be possible for an attacker to | |
access any file on the web server. [Tony Finch] | |
*) Fix a bug where errors that are detected during early request parsing | |
don't produce visible HTTP error messages at the browser, because | |
the core_filter wasn't present. [Greg Ames] | |
*) Provide apr_socklen_t as a portability aid. | |
[Victor J. Orlikowski] | |
*) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2) | |
as well as a comment arg to the add, adduser and update cmds. | |
update allows the user to clear or preserve pw/groups/comment. | |
Fixed a bug in dbmmanage that prevented the check option from | |
parsing a password followed by :group... text. Corrected the | |
seed calcualation for Win32 systems, and added -lsdbm support. | |
[William Rowe] | |
*) Configured mod_auth_dbm to compile with sdbmlib under Win32. | |
[William Rowe] | |
*) Avoid a segfault when parsing .htaccess files. An | |
uninitialized tree pointer was passed to ap_build_config(). | |
[Jeff Trawick] | |
*) Change the way that inet_addr & inet_network are checked for | |
in APR's configure process to allow BeOS BONE to correctly | |
find them. With this change BeOS BONE now builds from source | |
with no problems. [David Reid] | |
*) Fix a bug in apr_create_process() for Unix. The NULL signifying | |
the end of the parameters to execve() was stored in the wrong | |
location, overlaying the storage beyond the newargs[] array and | |
also passing uninitialized storage to execve(), which would | |
sometimes fail with EFAULT. [Jeff Trawick] | |
*) Fix a bug parsing configuration file containers. With a sequence | |
like this in the config file | |
<IfModule mod_kilroy.c> | |
any stuff | |
</IfModule> | |
<IfModule mod_lovejoy.c> | |
(blank line) | |
any stuff | |
</IfModule> | |
the second container would be terminated at the blank line due to | |
sediment in the buffer from reading the prior </IfModule> and an | |
error message would be generated for the real </IfModule> for the | |
second container. Also due to this problem, any two characters | |
could be used for "</" in the close of a container. | |
[Jeff Trawick] | |
*) ap_add_filter prototype changed to remove the ctx pointer. The | |
pointer still remains in the filter structure, but it can not be | |
a part of the ap_add_filter prototype. The reason is that when | |
the core uses AddFilter to add a filter to the stack it doesn't | |
know how to allocate the ctx pointer, or even how much memory should | |
be allocated. The filters will have to be responsible for allocating | |
the ctx memory when they need it. | |
[Ryan Bloom] | |
*) Add an AddFilter directive. This directive takes a list of filters | |
that should be activated for the requested resource. | |
[Ryan Bloom] | |
*) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps | |
some other platforms). [Jeff Trawick] | |
*) Modify mod_include to be a filter. Currently, it has only been tested | |
on actual files, but it should work for CGI scripts too. | |
[Ryan Bloom] | |
*) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted | |
writes. apr_flush() for Unix: handle interrupted writes. | |
[Jeff Trawick] | |
*) NameVirtualHost can now take "*" as an argument instead of | |
an IP address. This allows you to create a purely name-based | |
virtual hosting server that does not have any IP addresses in | |
the configuration file and which ignores the local address | |
of any connections. PR #5595, PR #4455 [Tony Finch] | |
*) Fix some compile warnings in mod_mmap_static.c | |
[Mike Abbott <mja sgi.com>] | |
*) Fix chunking problem with CGI scripts. The general problem was that | |
the CGI modules were adding an EOS bucket and then the core added an | |
EOS bucket. The chunking filter finalizes the chunked response when it | |
encounters an EOS bucket. Because two EOS buckets were sent, we | |
finalized the response twice. The fix is to make sure we only send one | |
EOS, by utilizing a flag in the request_rec. | |
[Ryan Bloom] | |
*) apr_put_os_file() now sets up the unget byte appropriately on Unix | |
and Win32. Previously, the first read from an apr_file_t set up via | |
apr_put_os_file() would return a '\0'. [Jeff Trawick] | |
*) Mod_cgid now creates a single element bucket brigade, with a pipe | |
bucket, instead of using BUFF's and ap_r*. | |
[Ryan Bloom] | |
*) APRVARS.in no longer overwrites the EXTRA_LIBS variable. | |
[Mike Abbott <mja sgi.com>] | |
*) Remove ap_bopenf from buff code. This required modifying the file_cache | |
code to use APR file's directly instead of going through BUFFs. | |
[Ryan Bloom] | |
*) Fix compile break on some platforms for mod_mime_magic.c | |
[John K. Sterling <sterling covalent.net>] | |
*) Fix merging of AddDefaultCharset directive. | |
PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>] | |
*) Minor revamp of the rlimit sections of code. We now test | |
explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit() | |
is now "available" even if the platform doesn't support | |
the rlimit family (it's just a noop though). [Jim Jagielski] | |
*) Migrate the pre-selection of which MPM to use for specific | |
platforms to hints.m4, which contains (or should contain) | |
all platform specific "hints". [Jim Jagielski] | |
*) Remove IOLs from Apache. With filtering, IOLs are no longer necessary | |
[Ryan Bloom] | |
*) Add tables with non-string/binary values to APR. | |
[Ken Coar] | |
*) Fix some bad calls to ap_log_rerror() in mod_rewrite. | |
[Jeff Trawick] | |
*) Update PCRE to version 3.2. [Ryan Bloom] | |
*) Change the way buckets' destroy functions are called so that | |
they can be more directly used when changing the type of a | |
bucket in place. [Tony Finch] | |
*) Add generic support for reference-counting the resources used by | |
buckets, and alter the HEAP and MMAP buckets to use it. Change | |
the way buckets are initialised to support changing the type of | |
buckets in place, and use it when setting aside TRANSIENT buckets. | |
Change the implementation of TRANSIENT buckets so that it can be | |
mostly shared with IMMORTAL buckets, which are now implemented. | |
[Tony Finch] | |
Changes with Apache 2.0a6 | |
*) Add support to Apache and APR for dsos on OS/390. [Greg Ames] | |
*) Add a chunking filter to Apache. This brings us one step closer | |
to removing BUFF. [Ryan Bloom] | |
*) ap_add_filter now adds filters in a LIFO fashion. The first filter | |
added to the stack is the last filter to be called. [Ryan Bloom] | |
*) Apache 2.0 has been completely documented using Scandoc. The | |
docs can be generated by running 'make docs'. [Ryan Bloom] | |
*) Add filtered I/O to Apache. This is based on bucket brigades, | |
Currently the buckets still use BUFF under the covers, but that | |
should change quickly. The only currently written filter is the | |
core filter which just calls ap_bwrite. [The Apache Group] | |
*) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't | |
built with thread support. [Jeff Trawick] | |
*) Abort configuration if --with-layout was specified and there's | |
no layout definition file. [Ken Coar] | |
*) Add support for '--with-port=n' option to configure. [Ken Coar] | |
*) Add support for extension methods for the Allow response header | |
field, and an API routine for accessing r->allowed and the | |
list of extension methods in a unified manner. [Ken Coar] | |
*) mod_cern_meta: fix broken file reading loop in scan_meta_file(). | |
[Rob Simonson <simo us.ibm.com>] | |
*) Get xlate builds working again. The apr renaming in 2.0a5 broke | |
APACHE_XLATE builds. [Jeff Trawick] | |
*) A configuration file parsing problem was fixed. When the | |
configuration file started with an IfModule/IfDefine container, | |
only the last statement in the container would be retained. | |
[Jeff Trawick] | |
Changes with Apache 2.0a5 | |
*) Perchild is serving pages after passing them to different child | |
processes. There are still a lot of bugs, but this does work. I | |
have made requests against the same installation of Apache, and had | |
different servers use different user IDs to serve the responses. | |
This change moves to using socketpair instead of an AF_UNIX socket. | |
[Ryan Bloom] | |
*) Perchild MPM still doesn't work perfectly, but it is serving pages. | |
It can't seem to pass between child processes yet, but I think we | |
are closer now than before. This moves us back to using Unix | |
Domain Sockets. [Ryan Bloom] | |
*) libapr functions and types renamed with apr_ prefix. | |
#include "apr_compat.h" for 1.3.x backwards compat | |
[Perl] | |
*) Fix problems with APR sockaddr handling on Win32. It didn't always | |
return the right information on the local socket address. | |
[Gregory Nicholls <gnicholls level8.com>] | |
*) ap_recv() on Win32: Set bytes-read to 0 on error. | |
[Gregory Nicholls <gnicholls level8.com>] | |
*) Add an option to not detach from the controlling terminal without | |
going into single process mode. This allows for much easier | |
debugging of the process startup code. [Ryan Bloom] | |
*) ab: don't use perror() to report the failure of an APR function. | |
[Jeff Trawick] | |
*) Make dexter, mpmt_pthread, and perchild MPMs not destroy the | |
scoreboard on graceful restarts. | |
[Ryan Bloom] | |
*) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c. | |
An invalid ap_proc_t was passed to ap_create_process(). | |
[Jeff Trawick] | |
*) Allow modules to register filters. Those filters are still | |
never called, but this is a step in the right direction. | |
[Ryan Bloom and Greg Stein] | |
*) Register the mod_cgid daemon process for cleanup so that it is | |
killed at termination if it does not die when the parent gets | |
SIGTERM. This change is to fix occasional problems where the | |
process stays around. Bugs in similar logic in mod_rewrite and | |
mod_include were also fixed. [Jeff Trawick] | |
*) Fix a bug in the time handling. Basically, we were imploding a time | |
in ap_parseHTTPdate, but it had bogus data in the exploded time format. | |
Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time | |
uses those two fields to adjust the time value. Because of the HTTP | |
spec, both of those values can be zero'ed out safely. This fixes | |
the bug correctly. [Ryan Bloom] | |
*) Fix a couple of place in the Windows code where the wrong error | |
code was being returned. [Gregory Nicholls <gnicholls level8.com>] | |
*) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet] | |
*) Added the APR_EOL_STR macro for platform dependent differences in | |
logfiles and other raw text (such as all APR files). Fixes logfiles | |
not terminated with cr/lf sequences in Win32. [William Rowe] | |
*) Move all strings functions in APR to src/lib/apr/strings and create | |
apr_strings.h for the prototypes. [Ryan Bloom] | |
*) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure | |
to repeat the syscall until we stop getting EINTR. I noticed a | |
related problem at termination (SIGTERM) on FreeBSD when using | |
fcntl(). Apache 1.3 had these new loops too. Also, make the flock() | |
implementation work properly with child init. Previously, ap_lock() | |
was essentially a no-op because all children were using different | |
locks and thus nobody ever blocked. [Jeff Trawick] | |
*) The htdocs/ tree has been moved out of the CVS source tree into | |
a separate area for easier development. This has NO EFFECT on | |
end-users or Apache installations. [Ken Coar] | |
*) Integrate the mod_dav module for WebDAV protocol handling. This | |
adds the dav and dav_fs modules, the SDBM library, and additional | |
XML handling utilities. [Greg Stein] | |
*) Clean out obsolete names (from httpd.h) for the HTTP Status Codes | |
[Greg Stein] | |
*) Update the lib/expat-lite/ library (bring forward changes from | |
the Apache 1.3 repository). [Greg Stein] | |
*) If sizeof(long long) == sizeof(long), then prefer long in APR | |
configure.in. [Dave Hill <ddhill zk3.dec.com>] | |
*) Add ap_sendfile for Tru64 Unix. Also, add an error message for | |
machines where sendfile is detected, but nobody has written ap_sendfile. | |
[Dave Hill <ddhill zk3.dec.com>] | |
*) Compile fixes in mod_mmap_static. [Victor J. Orlikowski] | |
*) ab would start up more connections than needed, then quit when the | |
desired number were finished. Also fixed a logic error involving | |
ab keepalives. [Victor J. Orlikowski] | |
*) WinNT: Implement non-blocking pipes with timeouts to communicate | |
with CGIs. Apache 2.0a4 had non-blocking pipes but without | |
timeouts (i.e, if a timeout was specified, the pipe reverted to | |
a full blocking pipe). Now the behaviour is more in line with | |
Unix non-blocking pipes. | |
[Bill Stoddard] | |
*) WinNT: Implement accept socket reuse. Using mod_file_cache to | |
cache open file handles along with accept socket reuse enables | |
Apache 2.0 to serve non-keepalive requests for static files at | |
3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps | |
and Apache 2.0 will serve almost 1200 rps on my system). | |
[Bill Stoddard] | |
*) Merge mod_mmap_static function into mod_file_cache. mod_file_cache | |
supports two config directives, mmapfile (same behavious as | |
mod_mmap_static) and cachefile. Use the cachefile directive | |
to cache open file handles. This directive only works on systems | |
that have implemented the ap_sendfile API. cachefile works today | |
on Windows NT, but has not been tested on any flavors of Unix. | |
[Bill Stoddard] | |
*) Cleanup the configuration. With the last few changes the | |
configuration process automatically: | |
inherits information about how to build from APR. Allowing | |
APR to inform Apache that it should or should not use -ldl | |
Detects which mod_cgi should be used mod_cgi or mod_cgid, | |
based on the threading model | |
Apache calls APR's configure process before finishing it's | |
configuration processing, allowing for more information flow | |
between the two. | |
[Ryan Bloom] | |
*) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK | |
with non-zero argument makes the socket non-blocking. BeOS and | |
OS/2 already worked this way. [Jeff Trawick] | |
*) ap_close() now calls ap_flush() for buffered files, so write | |
operations work a whole lot better on buffered files. | |
[Jeff Trawick] | |
*) Fix error messages issued from MPMs which explain where to change | |
compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads). | |
[Greg Ames] | |
*) ap_create_pipe() now leaves pipes in blocking state. (This helps | |
reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is | |
now the way that the blocking state of a pipe is manipulated. | |
ap_block_pipe() is gone. [Jeff Trawick] | |
*) Correct the problem where the only local host name that the IP stack | |
can discover are 'undotted' private names. If no fully qualified | |
domain name can be identified, the default ServerName will be set to | |
the machine's IP address string. A warning is always provided if the | |
ServerName not specified, but assumed. Solves PR6215 [William Rowe] | |
*) Repair problems with config file processing which caused segfault | |
at init when virtual hosts were defined and which caused ServerName to | |
be ignored when there was no valid DNS setup. [Jeff Trawick] | |
*) Removed pointless ap_is_aborted macro function. [Roy Fielding] | |
*) Add ap_sendfile implementation for AIX | |
[Victor J. Orlikowski] | |
*) Repair C++ compatibility in ap_config.h, apr_file_io.h, | |
apr_network_io.h, and apr_thread_proc.h. | |
[Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick] | |
*) Bring the allocation and pool debugging code back into a working | |
state. This will need to be tested as so far it's only been used on | |
BeOS. [David Reid] | |
*) Change configuration command setup to be properly typesafe when in | |
maintainer mode. Note that this requires a compiler that can initialise | |
unions. [Ben Laurie] | |
*) Turn on buffering for config file reads. Part of this was to | |
repair buffered I/O support in Unix and implement buffered | |
ap_fgets() for all platforms. [Brian Havard, Jeff Trawick] | |
*) Win32: Fix problem where UTC offset was not being set correctly | |
in the access log. Problem reported on news group by Jerry Baker. | |
[Bill Stoddard] | |
*) Fix segfault when reporting this type of syntax error: | |
"</container> without matching <container> section", where | |
container is VirtualHost or Directory or whatever. | |
[Jeff Trawick] | |
*) SECURITY [CAN-2000-1204] (cve.mitre.org): | |
Prevent the source code for CGIs from being revealed when | |
using mod_vhost_alias and the CGI directory is under the document root | |
and a user makes a request like http://www.example.com//cgi-bin/cgi | |
as reported in <news:960999105.344321 ernani.logica.co.uk> | |
[Tony Finch] | |
*) Add support for the new Beos NetwOrking Environment (BONE) | |
[David Reid] | |
*) xlate: ap_xlate_conv_buffer() now tells the caller when the | |
final input char is incomplete; ap_bwrite_xlate() now handles | |
incomplete final input chars. [Jeff Trawick] | |
*) Yet another update to saferead/halfduplex stuff -- need to ensure | |
that a bhalfduplex call occurs before logging or else DNS and | |
such can delay the last packet of the response. [Dean Gaudet] | |
*) Some syscall reduction in APR on unix -- don't seek when setting | |
up an mmap; and don't fcntl() more than once per socket. | |
[Dean Gaudet] | |
*) When mod_cgid is started as root, the cgi daemon now switches | |
to the configured User/Group (like other httpd processes) | |
instead of continuing as root. [Jeff Trawick] | |
*) The prefork MPM now uses an APR lock for the accept() mutex. | |
It has not been getting a lock at all recently. httpd -V now | |
displays APR's selection of the lock mechanism instead of the | |
symbols previously respected by prefork. [Jeff Trawick] | |
*) Change the mmap() feature test to check only for existence. | |
The previous check required features not used by Apache. | |
[Greg Ames] | |
*) Fix a couple of bugs in mod_cgid: The cgi arguments were | |
sometimes mangled. The len parm to accept() was not | |
initialized, leading sometimes to an endless loop of failed | |
accept() calls on OS/390 and anywhere else that failed the call | |
if the len was negative. Use <sys/un.h> for struct sockaddr_un | |
instead of declaring it ourselves to fix a compilation problem | |
on Solaris. [Jeff Trawick] | |
*) Add Resource limiting code back into Apache 2.0. [Ryan Bloom] | |
*) Fix zombie process problem with mod_cgi. [Jeff Trawick] | |
*) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames] | |
*) Fix storage overlay when loading dsos. Symptom: Apache dies at | |
initialization if ALLOC_DEBUG is defined; no known symptom | |
otherwise. [Jeff Trawick] | |
*) Fix typo in configure script when checking for mod_so. bash | |
doesn't seem to have a problem but /bin/sh on Solaris does. | |
Symptom: "./configure: test: unknown operator ==" | |
[Jeff Trawick] | |
*) Rebind the Win32 NT and 9x services control into the MPM. | |
All console, WinNT SCM and Win9x pseudo-service control code is | |
now wrapped within the WinNT MPM. | |
[William Rowe] | |
*) Make a copy of getenv("PATH") before storing for later use. Some | |
getenv() implementations use the same storage for successive calls. | |
CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick] | |
*) Server Tokens work in 2.0 again. This also propogates the change | |
to allow just the product name in the server string using | |
PRODUCT_ONLY. | |
[Ryan Bloom] | |
Changes with Apache 2.0a4 | |
*) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers | |
won't need to call it. [Greg Ames, Jeff Trawick] | |
*) Move pre_config hook call to between configuration read and config | |
tree walk. This allows all modules to implement pre_config hooks | |
and know that they will be called at an appropriate time. | |
[Ryan Bloom] | |
*) mod_cgi, mod_cgid: Make ScriptLog directive work again. | |
[Jeff Trawick] | |
*) Add pre-config hooks back to all modules. | |
[Ryan Bloom] | |
*) Fix a SIGSEGV in ap_md5digest(), which is used when you have | |
ContentDigest enabled and we can't/don't mmap the file. | |
[Jeff Trawick] | |
*) We now report the correct line number for syntax errors in config | |
files. [Ryan Bloom, Greg Stein, Jeff Trawick] | |
*) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t- | |
related bugs, and changed shmem/locking to use apr API. Shared-mem | |
is currently disabled, however, because of problems with graceful | |
restarts. [Ronald Tschalär] | |
*) Fix corruption of IFS variable in --with-module= handling. | |
Depending on the user's shell or customization thereof, there | |
would be errors generating ap_config_auto.h later in the configure | |
procedure. [Jeff Trawick] | |
*) mod_cgi: Restore logging of stderr from child process when ScriptLog | |
isn't used (as in 1.3), except that on Unix it is now logged via | |
ap_log_rerror() instead of by the child having STDERR_FILENO refer | |
to the error log. [Greg Ames, Jeff Trawick] | |
*) Add '-D' argument processing for run time configuration defines. | |
[William Rowe] | |
*) Organize http_main.c as independent code, such that no code or | |
global data is exported from it. WIN32 will dynamically link it | |
to the server core, so this will prevent mutual dependency. | |
[William Rowe] | |
*) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD() | |
and APR_VAR_EXPORT to correctly resolve apr functions and globals. | |
[William Rowe] | |
*) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers. | |
[William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>] | |
*) Add mod_charset_lite for configuring character set translation. | |
[Jeff Trawick] | |
*) Add '-n' option to htpasswd to make it print its user:pw record | |
on stdout rather than having to frob a text file. [Ken Coar] | |
*) Fix saferead. Basically, we flush the output buffer if a read on the | |
input will block. | |
[Ryan Bloom] | |
*) APR: Add ap_xlate_get_sb() so that an app can find out whether or not | |
a conversion is single-byte only. [Jeff Trawick] | |
*) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that | |
the BeOS 5.0 documentation says that shutdown doesn't work yet. | |
[Roy Fielding] | |
*) Fix some minor errors where pid was being manipulated as an int | |
instead of the portable pid_t. [Roy Fielding] | |
*) Fix some error log prints that were printing the pointer to a | |
structure rather than the pid within the structure. | |
[Jeff Trawick, Roy Fielding] | |
*) ab: Fix a command-line processing bug; track bad headers in | |
err_response; support reading headers up to 2K. | |
[Ask Bjoern Hansen <ask valueclick.com>] | |
*) Fix ap_resolve_env() so that it handles new function added in a prior | |
alpha (see "Added the capability to do ${ENVVAR} constructs in the | |
config file.") as well as the constructs used by mod_rewrite. | |
[Paul Reder <rederpj raleigh.ibm.com>] | |
*) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames] | |
*) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use | |
APR to perform translation, instead of accessing the hard-coded tables | |
in 1.3's ebcdic.c. [Jeff Trawick] | |
*) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing. | |
[Jeff Trawick] | |
*) Add the ability to hook into the config file reading phase. Basically | |
if a directive is specified EXEC_ON_READ, then when that directive is | |
read from the config file, the assocaited function is executed. This | |
should only be used for those directives that must muck with HOW the | |
server INTERPRETS the config. This should not be used for directives | |
that re-order or replace items in the config tree. Those changes should | |
be made in the pre-config step. | |
[Ryan Bloom] | |
*) Add mod_example to the build system. | |
[Tony Finch] | |
*) APR: Add ap_xlate_conv_byte() to convert one char between single- | |
byte character sets. [Jeff Trawick] | |
*) Pick up various EBCDIC fixes from 1.3 (from Martin | |
Kraemer and Oliver Reh originally according to the change log). | |
[Jeff Trawick] | |
*) Fix a couple of problems in RFC1413 support (controlled by the | |
IdentityCheck directive). Apache did not build the request string | |
properly and more importantly Apache would loop forever if the | |
would-be ident server dropped the connection before sending a | |
properly terminated response. [Jeff Trawick] | |
*) apxs works in 2.0. | |
[Ryan Bloom] | |
*) Reliable piped logs work in 2.0. | |
[Ryan Bloom] | |
*) Introduce a hash table implementation into APR to be used for | |
replacing tables and other random data structures in Apache. | |
[Tony Finch] | |
*) Add some more error reporting to htpasswd in the case of problems | |
generating or accessing the temporary file. Also, pass in a | |
buffer if the implementation knows how to use it (i.e., if L_tmpnam | |
is defined). [Ken Coar] | |
*) Configure creates config.nice now containing your configure | |
options. Syntax: ./config.nice [--more-options] | |
[Sascha Schumann] | |
*) Fix various return code problems in APR on Win32. For most of | |
these, APR was returning APR_EEXIST instead of GetLastError()/ | |
WSAGetLastError(). [Jeff Trawick] | |
*) Make piped logs work again in version 2.0 | |
[Ryan Bloom] | |
*) Add VPATH support to UNIX build system of Apache and APR. | |
[Sascha Schumann] | |
*) Fix ap_tokenize_to_argv to respect the const arguments that are | |
passed to it. | |
[Ryan Bloom] | |
*) Fix mm's memcpy/memset macros, pointer arithmetic was broken. | |
Patch submitted to author. | |
[Sascha Schumann] | |
*) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require | |
/sbin in PATH on FreeBSD (all submitted to rse previously) | |
[Jeff Trawick] | |
*) Fix building Pthread-based MPMs on OpenBSD | |
[Sascha Schumann] PR#26 | |
*) Fix ap_readdir() problem on systems where d_name[] field in | |
struct dirent is declared with only one byte. (This problem only | |
affected multithreaded builds.) This caused a segfault during | |
pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at | |
least). [Jeff Trawick] | |
*) Fix some make-portability problems on at least Tru64, Irix | |
and UnixWare. | |
[Sascha Schumann] PR#18, PR#39 | |
*) Add ap_sigwait() to support old-style sigwait() on systems | |
like OS/390 and UnixWare. | |
[Sascha Schumann] | |
*) Add POSIX-thread flags for more platforms. | |
[Sascha Schumann] | |
*) Fix some minor bugs in ap_strerror(). Teach ap_strerror() | |
(on Unix, at least) to handle resolver errors. Fix a bug in | |
the definition of APR_ENOMEM so that ap_strerror() can spit | |
out the correct error message for it. | |
[Jeff Trawick] | |
Changes with Apache 2.0a3 | |
*) mod_so reports ap_os_dso_error() if ap_dso_load() fails | |
[Doug MacEachern] | |
*) API: *HOOK* macros now have an AP_ prefix | |
[Doug MacEachern] | |
*) Win32: Eliminate redundant calls to initialize winsock. | |
[Tim Costello <timcostello ozemail.com.au>] | |
*) Fix bugs initializing ungetchar for pipes. | |
[Chia-liang Kao <clkao CirX.ORG>] | |
*) The ab program in the src/support directory is now portable using | |
APR. | |
[Ryan Bloom] | |
*) Support directory is being compiled when the server is built | |
[Ryan Bloom] | |
*) The configure option --with-program-name has been added to allow | |
developers to rename the executable at configure time. This also | |
changes the name of the config files to match the executable's name. | |
[Ryan Bloom] | |
*) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames | |
containing version numbers. [Martin Pool] | |
*) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on | |
Unix; access_log and error_log now created with these perms; non- | |
Unix is unaffected [Jeff Trawick] | |
*) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h. | |
Replaced more magic numbers with MD5_DIGESTSIZE. | |
[William Rowe, Roy Fielding] | |
*) Win32: Get mod_auth_digest compiling and added to the Windows | |
build environment. Not tested and I'd be suprised if it | |
actually works. [Bill Stoddard] | |
*) Revamp the Win32 make environment. Makefiles have been removed and | |
Apache.dsw created to bring together all the pieces. Create new file | |
os/win32/BaseAddr.ref to define module base addresses (to prevent | |
dll relocation at start-up). | |
[William Rowe, Greg Marr, Tim Costello, Bill Stoddard] | |
*) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most | |
of the \015, \012, and \015\012 constants with macros. | |
[Greg Ames] | |
*) Add ap_xlate_open() et al for translation of text between different | |
character sets. The initial implementation requires iconv(). | |
[Jeff Trawick] | |
*) More FAQs and answers from comp.infosystems.www.servers.unix. | |
[Joshua Slive <slive finance.commerce.ubc.ca>] | |
*) CGI output is being timed out now. | |
[Ryan Bloom] | |
*) Fix the problem with dieing quietly. dupfile now takes a pool which | |
is used by the new apr file. There is no reason to create a new file | |
with the same lifetime as the original file. | |
[Ryan Bloom] | |
*) Win32: Attempt to eliminate dll relocation at start-up by specifying | |
module base addresses. This will help shooting seg faults | |
in the field. [William Rowe <wrowe lnd.com>] | |
*) Update Apache on Windows documentation. Add new document | |
describing how to compile Apache on Windows. | |
[William Rowe <wrowe lnd.com>] | |
*) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take | |
microseconds instead of seconds. Some storage leaks and other | |
minor bugs in related code were fixed. [Jeff Trawick] | |
*) Win32: First cut at getting mod_isapi working under 2.0 | |
[William Rowe <wrowe lnd.com>] | |
*) First stab at getting mod_auth_digest working under 2.0 | |
quick change summary: | |
- moved the random byte generation (ap_generate_random_bytes) into APR | |
- now uses ap_time_t | |
- compiles and runs on linux | |
- tested with amaya | |
[Brian Martin <bmartin penguincomputing.com>] | |
*) Win32: Move the space stripping of physical service names | |
fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an | |
unresolved symbol. Add dependency checking to the | |
CreateService call to ensure TCPIP and AFP (winsock) is started | |
before Apache. | |
[William Rowe <wrowe lnd.com>] | |
*) Win32: Add code to perform latebinding on functions that may | |
not exist on all levels of Windows where Apache runs. This | |
is needed to allow Apache to start-up on Win95/98. All calls | |
to non portable functions should be protected with | |
ap_oslevel checks to prevent runtime segfaults. | |
[William Rowe <wrowe lnd.com>] | |
*) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer] | |
*) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick] | |
*) Win32: Get non-blocking CGI pipe reads working under Windows NT. | |
This addresses PR 1623. Still need to address timing out runaway | |
CGI scripts. [Bill Stoddard] | |
*) Win32: Make ap_stat Windows 95/98 friendly | |
[William Rowe <wrowe lnd.com>] | |
*) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to | |
always fail. Need to initialise the dwOSVersionInfoSize member of the | |
OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx | |
always fails. | |
The patch also enhances ap_get_oslevel (and the associated enum) to | |
handle selected service packs for NT4, and adds recognition for | |
Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then | |
we can use ReadFileScatter and WriteFileGather in readwrite.c. | |
[Tim Costello <Tim.Costello BTFinancialgroup.com>] | |
*) Get mod_rewrite building and running, and mod_status building for Win NT | |
[Allan Edwards <ake raleigh.ibm.com>] | |
*) Patch to port mod_auth_db to the 2.0 api and also to support | |
Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and | |
2.7.7. It should work with version 1 as well but I haven't tested it. | |
[Brian Martin <bmartin penguincomputing.com>] | |
*) Get APR DSO code working under Windows. Includes cross platform | |
fixes to mod_so.c. | |
[<Tim.Costello BTFinancialgroup.com>] | |
*) Fix some of the Windows APR time functions. | |
[William Rowe] | |
*) FAQ changes related to tidying up historical documents on the web site. | |
[Joshua Slive <slive finance.commerce.ubc.ca>] | |
*) Move Windows DSO code into APR. | |
[Bill Stoddard] | |
*) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause). | |
Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw | |
at build time. At this point, the server will not compile on Windows because | |
of the recent DSO commits. Fixing those next. | |
[Bill Rowe & Bill Stoddard] | |
*) Added error checking for file I/O APR routines. | |
[Jon Travis <jtravis covalent.net>] | |
*) APR: Don't use the values of resolver error codes for the | |
corresponding APR error codes. On Unix and Win32, return the | |
proper APR error code after a resolver error. [Jeff Trawick] | |
Changes with Apache 2.0a2 | |
*) Renamed the executable back to httpd on all platforms other | |
than Win32 | |
[Ryan Bloom] | |
*) Allow BeOS to survive restarts, log properly and a few | |
small things it had problems with due to the way it setup | |
users and groups. [David Reid] | |
*) Get mod_rewrite working with APR locks | |
[Paul Reder <rederpj raleigh.ibm.com>] | |
*) Actually remove the sempahore when the lock cleanup routine | |
is called on BeOS. [David Reid] | |
*) Clear hook registrations between reads of the config file. | |
When DSOs are unloaded and re-loaded the old hook pointers may | |
no longer be valid. This fix eliminates potential segfaults. | |
[Allan Edwards <ake raleigh.ibm.com>] | |
*) Fix a problem with Sigfunc not being defined or bypassed | |
if sigaction() wasn't found. [Jim Jagielski] | |
*) Fix the locking mechanism on BSD variants. They now use fcntl | |
locks. This allows the server to start and serve pages. | |
[Ryan Bloom] | |
*) First cut at getting the Win32 installer to work | |
[William Rowe <wrowe lnd.com>] | |
*) Get htpasswd compiling under Windows | |
[William Rowe <wrowe lnd.com>] | |
*) Change the log message for a bind() failure to show the | |
interface and port number. [Jeff Trawick] | |
*) Import the documentation from 1.3.12 and bring parts of it | |
up-to-date with respect to the changes that have occurred | |
in 2.0. | |
[Tony Finch] | |
*) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses | |
now logged correctly on BeOS. | |
[David Reid] | |
*) Create one makefile for all Win32 distributions (NT/2000/95/98). | |
Makefile.win includes the same user interface as the old | |
Makefile.nt | |
[William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>] | |
*) Win32 exec now uses COMSPEC environment string for command | |
shell path resolution. | |
[William Rowe <wrowe lnd.com>] PR#3715 | |
*) Win32: ap_connect() was not returning correct error condition | |
PR5866 | |
[Allen Prescott <allen clanprescott.com>] | |
*) Win32: ap_open() was broken on Win9x because an NT-specific | |
flag was passed to CreateFile. ap_puts() added an unnecessary | |
'\n'. | |
[Jeff Trawick <trawick us.ibm.com>] | |
*) Put in Korean and Norwegian index.html pages (2.0 and 1.3) | |
which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed' | |
confusing ee/et name and made all extensions language/dialect | |
rather than country reflecting. Changed example files to | |
explicit reflect the ISO charset and added a few common | |
ones to the example config [dirkx] | |
*) Extend external module capability. To use this, you call | |
configure with --with-module=path/to/mod1,path/to/mod2,etc. | |
[Ryan Bloom] | |
*) Backported the various "default charset" fixes from 1.3.12, | |
including the AddDefaultCharset directive. [Jim Jagielski] | |
*) Added the capability to do ${ENVVAR} constructs in the | |
config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited | |
it does this on a line by line basis; i.e. if the envvar | |
expands to something with spaces you have to protect it | |
by adding quotes around it (Unless of course you expect it | |
to contains more than one argument. Alternatively you | |
can compile it on a per token basis; which is what people | |
usually expect by setting RESOLVE_ENV_PER_TOKEN. But this | |
hampers fancier hacks. | |
[Dirk-Willem van Gulik] | |
*) Changed the 'ErrorDocument' syntax in that it NO longer | |
supports the asymetric | |
ErrorDocument 301 "Some message | |
Note the opening " quote, without a closing quote. It now | |
has either the following syntaxes | |
ErrorDocument XXX /local/uri | |
ErrorDocument XXX http://valid/url | |
ErrorDocument XXX "Some Message" | |
The recognition heuristic is: if it has a space it | |
is a message. If it has no spaces and starts with a / | |
or is a valid URL then treat it that way. Otherwise it | |
is assumed to be a message. | |
This breaks backward compatibility but makes live a hell | |
of a lot easier for GUI's and config file parsers. | |
[Dirk-Willem van Gulik] | |
*) Changed 'CacheNegotiatedDocs' from its present/not-present | |
syntax into a 'on' or 'off' syntax. As it currently is the | |
only non nesting token which uses NO_ARGS and thus is an | |
absolute pain for any config interface automation. This | |
breaks backward compatibility. [Dirk-Willem van Gulik] | |
*) Add ability to add external modules to the build process. This is | |
done with --with-module=/path/to/module. Modules can only be added | |
as static modules at this point. | |
[Ryan Bloom] | |
Changes with Apache 2.0a1 | |
*) Fix FreeBSD 3.3 core dump. | |
Basically, ap_initialize() needs to get called before | |
create_process(), since create_process() passes op_on structure | |
to semop() to get a lock, but op_on isn't initialized until | |
ap_initialize() calls setup_lock(). Here is a slight | |
rearrangement to main() which calls ap_initialize() earlier... | |
[Jeff Trawick <trawick us.ibm.com>] | |
*) Enable Apache to use sendfile/TransmitFile API | |
[Bill Stoddard, David Reid, Paul Reder] | |
*) Re-Implement Win32 APR network I/O APIs and most of the file I/O | |
APIs. | |
[Bill Stoddard] | |
*) Make file I/O and network I/O writev/sendv APIs consistent. | |
Eliminate use of ap_iovec_t and use Posix struct iovec. | |
Use seperate variable on ap_writev to set the number of iovecs | |
passed in and number of bytes written. | |
[Bill Stoddard] | |
*) Adapt file iol to use APR functions. Replaced ap_open_file() | |
with ap_create_file_iol(). ap_create_file_iol() requires that | |
the file be opened prior to the call using ap_open(). | |
[Bill Stoddard] | |
*) Port mod_include and mod_cgi to 2.0 | |
[Paul Reder, Bill Stoddard] | |
*) ap_send{,v}, ap_recv, ap_sendfile API clarification -- | |
bytes_read/bytes_written is always valid (never -1). Plus | |
some fixes to buff.c to correct problems introduced by the | |
errno => ap_status_t changes a while back. Plus a fix to | |
chunked encoding introduced right at the beginning of 2.0. | |
[Dean Gaudet] | |
*) Revamped UNIX build system to use autoconf and libtool. | |
[Manoj Kasichainula, Sascha Schumann] | |
*) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>] | |
*) SECURITY: More rigorous checking of Host: headers to fix security | |
problems with mass name-based virtual hosting (whether using mod_rewrite | |
or mod_vhost_alias). | |
[Ben Hyde, Tony Finch] | |
*) Add back support for UseCanonicalName in <Directory> containers. | |
[Manoj Kasichainula] | |
*) Added APLOG_STARTUP log type. This allows us to write an error | |
message without any of the date and time information. As a part | |
of this change, I also removed all of the calls to fprintf(stderr | |
and replaced them with calls to ap_log_error using APLOG_STARTUP | |
writing to stderr is no longer portable, because we don't direct | |
stderr to the error log on all platforms. | |
[Ryan Bloom] | |
*) Convert error logging functions to take errno as an argument. | |
This makes our error logs more portable, because some Windows API's | |
don't set errno. This change allows us to still output a valid | |
message on all of our platforms. | |
[Ryan Bloom] | |
*) mod_mime_magic runs in 2.0-dev now. | |
[Paul Reder <rederpj raleigh.ibm.com>] | |
*) sendfile has been added to APR. | |
[John Zedlewski <zedlwski Princeton.EDU>] | |
*) buff.c has been converted to no longer use errno. | |
[Manoj Kasichainula] | |
*) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and | |
interface adaption to APR functions did it. [Martin Kraemer] | |
*) Support DSOs properly on 32-bit HP-UX 11.0 | |
[Dilip Khandekar <dilip cup.hp.com>] | |
*) Updated MM in APR source tree from version 1.0.8 to 1.0.11 | |
[Ralf S. Engelschall] | |
*) Cleaned APR build environment integration and bootstrap APR | |
automatically for developers from src/Configure. | |
[Ralf S. Engelschall] | |
*) Fixed building of src/support/htpasswd.c | |
[Ralf S. Engelschall] | |
*) When generating the Location: header, mod_speling forgot | |
to escape the spelling-fixed uri. (Forw-Port from 1.3) | |
[Martin Kraemer] | |
*) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding] | |
*) Change all pools to APR contexts. This is the first step to | |
incorporating APR into Apache. [Ryan Bloom] | |
*) Move "handler not found" warning message to below the check | |
for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding] | |
PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807 | |
*) Support line-continuation feature in config.option file and | |
allow the loading of multiple option sections at once via | |
``--with-option=<section1>,<section2>,...'' | |
[Ralf S. Engelschall] | |
*) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding] | |
Changes with Apache MPM | |
*) Use asynchronous AcceptEx() and a completion port to accept and | |
dispatch connections to threads in Windows NT/2000. | |
[Bill Stoddard] | |
*) Implement WINNT Win32 MPM from original Win32 code in http_main.c | |
[Bill Stoddard] | |
*) Implement the APACI --with-option facility | |
(per default used the config.option file). | |
[Ralf S. Engelschall] | |
*) MPM BEOS port. [David Reid <abb37 dial.pipex.com>] | |
*) Start to implement module-defined hooks that are a) fast and b) typesafe. | |
Replace pre_connection module call with a register_hook call and | |
implement pre_connection as a hook. The intent is that these hooks will | |
be extended to allow Apache to be multi-protocol, and also to allow the | |
calling order to be specified on a per-hook/per-module basis. | |
[Ben Laurie] | |
*) Implement mpm_* methods as "modules". Each method gets its own | |
subdir in src/modules (eg: src/modules/prefork). Selection | |
of method uses Rule MPM_METHOD. [Jim Jagielski] | |
*) Port the hybrid server from the apache-apr repository as | |
mpm_mpmt_pthread. [Manoj Kasichainula] | |
*) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common | |
amongst the unix MPMs. | |
*) mpm_prefork: throw away all the alarm/timeout crud; and clean up the | |
signal handling for the new world order. [Dean Gaudet] | |
*) Crude ap_thread_mutex abstraction so that we get the pthread stuff out | |
of alloc.c for now. [Dean Gaudet] | |
*) Handle partial large writes correctly. [Ben Laurie] | |
*) Eliminate conn_rec's pointer to server. All it knows is the base server | |
based on IP/port. [Ben Laurie] | |
*) Port a bunch of modules to the new module structure. | |
["Michael H. Voase" <mvoase midcoast.com.au>] | |
*) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet] | |
*) Basic restructuring to introduce the MPM concept; includes various | |
changes to the module API... better described by | |
docs/initial_blurb.txt. [Dean Gaudet] | |
Changes with Apache pthreads | |
*) New buff option added: BO_TIMEOUT. It describes the timeout for | |
buff operations (generally over a network). | |
[Dean Gaudet, Ryan Bloom, Manoj Kasichainula] | |
*) Created http_accept abstraction. Added 4 new functions (not exported): | |
init_accept(), begin_accepting_requests(), get_request(), | |
stop_accepting_requests() [Bill Stoddard] | |
*) Fix to ap_rprintf call that allows mod_info to work properly. | |
[James Morris <jmorris intercode.com.au>] | |
*) user and ap_auth_type fields were moved from connection_rec to | |
request_rec. [Ryan Bloom] | |
*) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't | |
needed in a threaded server. | |
*) Initial pthread implementation from from Dean's apache-nspr code. | |
[Bill Stoddard, Ryan Bloom] | |
Changes with Apache 1.3.9 | |
*) Remove bogus error message when a redirect doesn't set Location. | |
Instead, use an empty string to avoid coredump if the error message | |
was supposed to include a location. [Roy Fielding] | |
*) Don't allow configure to include mod_auth_digest unless it is | |
explicitly requested, even if the user asked for all modules. | |
[Roy Fielding] | |
*) Translate module names to dll names for OS/2 so that they are no more | |
than 8 characters long and have an extension of "dll" instead of "so". | |
[Brian Havard] | |
*) Print out pointer to Rule DEV_RANDOM when truerand lib not found. | |
Fix test-compile check to check for randbyte instead of trand32. | |
Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c | |
and tweak to make Amaya happier. [Ronald Tschalär] | |
*) Ensure that the installed expat include files are world readable, | |
just like the other header files. [Martin Kraemer] | |
*) Fixed generated AddModule adjustments in APACI's `configure' script | |
in order to allow (new) modules like mod_vhost_alias to be handled | |
correctly (which was touched by the adjustments for mod_alias). | |
[Ralf S. Engelschall] | |
*) For binary builds, add -R flag to apachectl to work around the lack of | |
an absolute path to the ./libexec directory where the libhttp.ep file | |
is needed for SHARED_CORE architectures. [Randy Terbush] | |
*) WIN32: Create the CGI script process as DETACHED. This may solve the | |
problem observed by some Win95/98 users where they get CGI script | |
output sent to the console. [Bill Stoddard] | |
*) Fix (re)naming in the uuencode/decode section. The ap/ap_ | |
routines are now called ap_base64* and are 'plain' (i.e., no | |
pool access or anything clever). Inside util.c the routines acting | |
like pstrdup are called ap_pbase64encode() and ap_pbase64decode(). | |
The oddly named ap_uuencode(), ap_uudecode() are kept around for | |
now but deprecated. [dirkx] | |
*) Clean up the base64 and SHA1 additions and make sure they are | |
represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp | |
files. [Roy Fielding] | |
*) WIN32: Migrate to InstallShield 5.5 and provide a bit more error | |
checking. Allow compiling on VS 6.0. [Randy Terbush] | |
*) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch] | |
*) Use TestCompile to search for the truerand library (rather than blindly | |
assuming its existence). If it is not found, complain (but do not | |
exit - yet). [Martin Kraemer] | |
*) We forgot to add the new exported function names to | |
src/support/httpd.exp. [Bill Stoddard, Randy Terbush] | |
*) Add description of -T command-line option to usage(). | |
[Ralf S. Engelschall] | |
*) For "some" platforms (notably, EBCDIC based ones), libos needs to be | |
searched only AFTER libap has been searched, because libap needs | |
some symbols from libos. [Martin Kraemer] | |
*) Fix conflict with original mod_digest related to the symbol of the | |
module dispatch list (which has to be unique for DSO and follow the | |
usual conventions for the installation procedure). | |
[Ralf S. Engelschall] | |
*) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb) | |
for other platforms as well. [Martin Kraemer] | |
*) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG | |
types by AP_LONG and replace reference to renamed variable 'ubuf' | |
by 'buffer'. [Martin Kraemer] | |
Changes with Apache 1.3.8 [not released] | |
*) Flush the output buffer immediately after sending an error or redirect | |
response, since the result may be needed by the client to abort a | |
long data transfer or restart a series of pipelined requests. | |
[Tom Vaughan <tvaughan aventail.com>, Roy Fielding] | |
*) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx. | |
[Ian Turner <iant sequent.com>] PR#4735 | |
*) Local struct mmap in http_core.c conflicted with system structure | |
name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735 | |
*) Added updated mod_digest as modules/experimental/mod_auth_digest. | |
[Ronald Tschalär <ronald innovation.ch>] | |
*) Fix a memory leak where the module counts were getting messed | |
up across restarts. [David Harris <dharris drh.net>] | |
*) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled | |
properly in mod_access. | |
["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770 | |
*) RewriteLock/RewriteMap didn't work properly with virtual hosts. | |
[Dmitry Khrustalev <dima bog.msu.su>] PR#3874 | |
*) PORT: Support for compaq/tandem/com. | |
[Michael Ottati <michael.ottati compaq.com>, dirkx] | |
*) Added SHA1 password encryption support to easy migration from | |
Netscape servers. See support/SHA1 for more information. | |
Caused the separation of ap_md5.c into md5, sha1 and a general | |
ap_checkpass.c with just a validate_passwd routine. Added a | |
couple of flags to support/htpasswd. Some reuse of the to64() | |
function; hence renamed to ap_to64(). | |
[Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>] | |
*) Change for EBCDIC platforms (TPF and BS2000) to correctly deal | |
with ASCII/EBCDIC conversions in "ident" query. | |
[David McCreedy <McCreedy us.ibm.com>] | |
*) Get rid of redefinition warning on MAC_OS_X_SERVER platform. | |
Change "Power Macintosh" to Power* so if uname prints "Power Book" | |
we're still happy on Rhapsody platforms. [Wilfredo Sanchez] | |
*) Fix SIGSEGV on some systems because the Vary fix below included | |
a call to table_do with a variable argument list that was not | |
NULL terminated. Replaced with better implementation. [Roy Fielding] | |
Changes with Apache 1.3.7 [not released] | |
*) The "Vary" response header field is now sanitised right before | |
the header is sent back to the client. Multiple "Vary" fields | |
are combined, and duplicate tokens (e.g., "Vary: host, host" or | |
"Vary: host, negotiate, host, accept-language") are reduced to | |
single instances. This is a better solution than the force-no-vary | |
one (which is still valid for clients that can't cope with Vary | |
at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar] | |
*) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>] | |
*) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at | |
least on Linux and FreeBSD for now. | |
[Rasmus Lerdorf] | |
*) Win32: More apache -k restart work. Restarts are now honored | |
immediately and connections in the listen queue are -not- lost. | |
This is made possible by the use of the WSADuplicateSocket() | |
call. The listeners are opened in the parent, duplicated, then | |
the duplicates are passed to the child. The original listen sockets | |
are not closed by the parent across a restart, thus the listen queue | |
is preserved. | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |
*) Fix handling of case when a client has sent "Expect: 100-continue" | |
and we are going to respond with an error, but get stuck waiting to | |
discard the body in the pointless hope of preserving the connection. | |
[Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806 | |
*) Fix 'configure' to work correctly with SysV-based versions of | |
'tr' (consistent with Configure's use as well). [Jim Jagielski] | |
*) apxs: Add "-S var=val" option which allows for override of CFG_* | |
built-in values. Add "-e" option which works like -i but doesn't | |
install the DSO; useful for editing httpd.conf with apxs. Fix | |
editing code so that multiple invocations of apxs -a will not | |
create duplicate LoadModule/AddModule entries; apxs can now be | |
used to re- enable/disable a module. [Wilfredo Sanchez] | |
*) Win32: Update the server to use Winsock 2. Specifically, link with | |
ws2_32.lib rather than wsock32.lib. This gives us access to | |
WSADuplcateSocket() in addition to some other enhanced comm APIs. | |
Win 95 users may need to update their TCP/IP stack to pick up | |
Winsock 2. (See http://www.microsoft.com/windows95/downloads/) | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |
*) Win32: Redirect CGI script stderr (script debug info) into the | |
error.log when CGI scripts fail. This makes Apache on Win32 | |
behave more like Unix. | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |
*) Fixed `httpd' usage display: -D was missing. | |
[Ralf S. Engelschall] PR#4614 | |
*) Fix `make r' test procedure in src/regex/: ap_isprint was not found. | |
[Ralf S. Engelschall] PR#4561, PR#4562 | |
*) OS/2: Fix problem with accept lock semaphores where server would die with | |
"OS2SEM: Error 105 getting accept lock. Exiting!" | |
[Brian Havard] PR#4505 | |
*) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms. | |
[Randy Terbush <randy covalent.net>] | |
*) Add the new mass-vhost module (mod_vhost_alias.c) developed and | |
used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>] | |
*) Better GCC detection for DSO flags under Solaris 2 where the `cc' | |
command potentially _is_ GCC. [Ralf S. Engelschall] | |
*) Fix apxs build issues on AIX | |
[Rasmus Lerdorf <rasmus raleigh.ibm.com>] | |
*) DocumentRoot Checking: Under previous versions, when Apache | |
first started up, it used to do a stat of each DocumentRoot to | |
see if it existed and was a directory. If not, then an error | |
message was printed. THIS HAS BEEN DISABLED. If DocumentRoot | |
does not exist, you will get error messages in error_log. If | |
the '-t' command line option is used (to check the configuration) | |
the check of DocumentRoot IS performed. An additional command | |
line option, '-T', has been added if you want to avoid the | |
DocumentRoot check even when checking the configuration. | |
[Jim Jagielski] | |
*) Win32: The query switch "apache -S" didn't exit after showing the | |
vhost settings. That was inconsistent with the other query functions. | |
[Bill Stoddard - Fixed by Martin on Unix in 1.3.4] | |
*) Win32: Changed behaviour of apache -k restart. | |
Previously, the server would drain all connections in the stack's | |
listen queue before honoring the restart. On a busy server, this | |
could take hours. Now, a restart is honored almost immediately. | |
All connections in Apache's queues are handled but connections in | |
the stack's listen queue are discarded. Restart triggered by | |
MaxRequestPerChild is unchanged. | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |
*) Win32: Eliminated unnecessary call to wait_for_multiple_objects in | |
the accept loop. Good for a 5% performance boost. Cleaned up | |
parent/child process management code. | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |
*) Added ceiling on file size for memory mapped files. | |
[John Giannandrea <jg meer.net>] PR#4122 | |
*) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which | |
has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528 | |
[Henri Gomez <gomez slib.fr>, Ralf S. Engelschall] | |
*) Determine AP_BYTE_ORDER for ap_config_auto.h and already | |
use this at least for Expat. [Ralf S. Engelschall] | |
*) Allow .module files to specify libraries with Lib:. | |
[Ben Laurie] | |
*) Allow SetEnvIf[NoCase] to test environment variables as well | |
as header fields and request attributes. [Ken Coar] | |
*) Fix mod_autoindex's handling of ScanHTMLTitles when file | |
content-types are "text/html;parameters". PR#4524 [Ken Coar] | |
*) Remove "mxb" support from mod_negotiation -- it was a draft feature | |
never accepted into any standard, and it opens up certain DoS | |
attacks. [Koen Holtman <Koen.Holtman cern.ch>] | |
*) TestCompile updated. We can now run programs and output the | |
results during the Configure process. [ Jim Jagielski] | |
*) The source is now quad (long long) aware as needed. Specifically, | |
the Configure process determines the correct size of off_t and | |
*void. When the OS/platform/compiler supports quads, ap_snprintf() | |
provides for the 'q' format qualifier (if quads are not available, | |
'q' is silently "demoted" to long). [Jim Jagielski] | |
*) When the username or password fed to htpasswd is too long, include the | |
size limit in the error message. Also report illegal characters | |
(currently only ':') in the username. Add the size restrictions | |
to the man page. [Ken Coar] | |
*) Fixed the configure --without-support option so it doesn't result in | |
an infinite loop. [Marc Slemko] | |
*) Piped error logs could cause a segfault if an error occured | |
during configuration after a restart. | |
[Aidan Cully <aidan panix.com>] PR#4456 | |
*) If a "Location" field was stored in r->err_headers_out rather | |
than r->headers_out, redirect processing wouldn't find it and | |
the server would core dump on ap_escape_html(NULL). Check both | |
tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message | |
if Location isn't set. [Doug MacEachern, Ken Coar] | |
*) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy | |
of the Expat 1.0.2 distribution. [Greg Stein] | |
*) Replace regexec() calls with calls to a new API stub function | |
ap_regexec(). This solves problems with DSO modules which use the regex | |
library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall] | |
*) Add 'Request_Protocol' special keyword to mod_setenvif so that | |
environment variables can be set according to the protocol version | |
(e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar] | |
*) Add DSO support for OpenStep (Mach 4.2) platform. | |
[Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997 | |
*) Fix sed regex for generating ap_config_auto.h in src/Configure. | |
[Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373 | |
*) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with | |
their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372 | |
*) Better DSO flags recognition on NetBSD platforms using ELF. | |
[Todd Vierling <tv pobox.com>] PR#4310 | |
*) Always log months in english format for %t in mod_log_config. | |
[Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679 | |
*) Support for server-parsed and multiview-determined ReadmeName and | |
HeaderName files in mod_autoindex. Removed the restriction on | |
"/"s in ReadmeName and HeaderName directives since the *sub_req* | |
routines will deal with the access issues. (It's now possible to | |
have {site|group|project|customer|...} wide readmes and headers.) | |
[Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529, | |
3569, 4256 | |
*) When stat() fails, don't assume anything about the contents of | |
the struct stat. [Ed Korthof <ed bitmechanic.com>] | |
*) It's OK for a semop to return EINTR, just loop around and try | |
again. [Dean Gaudet] | |
*) Fix configuration engine re-entrant hangups, which solve a | |
handful of problems seen with mod_perl <Perl> configuration sections | |
[Salvador Ortiz Garcia <sog msg.com.mx>] | |
*) Mac OS and Mac OS X Server now use the appropriate custom layout | |
by default when building with APACI; allow for platform-specific | |
variable defaults in configure. [Wilfredo Sanchez] | |
*) Do setgid() before initgroups() in http_main; some platforms | |
zap the grouplist when setgid() is called. This was fixed in | |
suexec earlier, but the main httpd code missed the change. | |
[Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579 | |
*) Add recognition of .tgz as a gzipped tarchive. | |
[Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364 | |
*) mod_include's fsize/flastmod should allow only relative paths, just | |
like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>] | |
*) OS/2: Add support for building loadable modules using DLLs. | |
[Brian Havard] | |
*) Add iconsdir, htdocsdir, and cgidir to config.layout. | |
[Wilfredo Sanchez] | |
*) Fix minor but annoying bug with the test for Configuration.tmpl | |
being newer than Configuration so that it is less likely to fail | |
when using APACI and shadow sources. [Wilfredo Sanchez] | |
*) PORT: Add initial support for Mac OS (versions 10.0 and | |
greater). Use Mac OS X Server layout for now. Clean up dyld code | |
in unix/os.c, and don't install the dyld error handlers, which | |
are no longer needed in Mac OS. [Wilfredo Sanchez] | |
*) Rename Rhapsody layout to "Mac OS X Server". Change install | |
locations to appropriate ones for user-built (as opposed to | |
system) installs. [Wilfredo Sanchez] | |
*) Modify mod_autoindex's handling of AddDescription so that the | |
behaviour matches the documentation. [Ken Coar] PR#1898, 3072. | |
*) Add functionality to the install-bindist.sh script created by | |
binbuild.sh to use tar when copying distribution files to the | |
serverroot. This allows upgrading an existing installation | |
without nesting the new distribution in the old. | |
install-bindist.sh now detects the local perl5 path to install | |
apxs and dbmmanage with proper path to perl interpreter. | |
Add an install-binsupport target which copies the source files | |
for apxs and dbmmanage to bindist to allow these scripts to | |
be properly installed relative to the destination serverroot. | |

a) the htdigest utility overwrote the old contents of the digest file | |
b) the Content-MD5 header value (ContentDigest directive) was wrong | |
when the returned file was not converted from EBCDIC, but was a | |
binary (e.g., image file) in the first place. | |
[David McCreedy <mccreedy us.ibm.com>] | |
*) support/htpasswd now permits the password to be specified on the | |
command line with the '-b' switch. This is useful when passwords | |
need to be maintained by scripts -- particularly in the Win32 | |
environment. [Ken Coar] | |
*) Win32: Win32 multiple services patch. Added capability to install and | |
run multiple copies of apache as individual services. | |
Example 1: | |
apache -n apache1 -i -f c:/httpd.conf | |
Installs apache as service 'apache1' and associates c:/httpd.conf | |
with that service. | |
net start apache1 | |
Starts apache1 service. | |
net stop apache1 | |
Stops apache1 service | |
Example 2: | |
apache -n apache2 -i | |
Installs apache as service 'apache2'. httpd.conf is located under | |
the default server root (/apache/conf/httpd.conf). | |
net start apache2 | |
Starts apache2 service. | |
Example 3: | |
apache -n apache3 -i -d c:/program files/apache | |
Install apache as service 'apache3' and sets server root to | |
c:/program files/apache. | |
Example 4: | |
apache -n apache2 -k restart | |
Restart apache2 service | |
[Keith Wannamaker, Ken Parzygnat, Bill Stoddard] | |
*) Correct the signed/unsigned character handling for the MD5 routines; | |
mismatches were causing compilation problems with gcc -pedantic and | |
in the TPF cross-compilation. [Ken Coar] | |
*) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving | |
a roughly 5 fold speed up. [Brian Havard] | |
*) proxy ftp: instead of using the hardwired string "text/plain" as | |
a fallback type for files served by the ftp proxy, use the | |
ap_default_type() function to determine the configured type. | |
This allows for special configurations like | |
<Directory proxy:ftp://some.host> | |
DefaultType gargle/blurb | |
</Directory> | |
Additionally, add the Content-Encoding: header to FTP proxy replies | |
when the encoding is defined (by the AddEncoding directive). | |
Because it was missing, it was almost impossible to browse compressed | |
files using the FTP proxy (works now perfectly in Communicator). | |
The ftp proxy now also returns the Date: and Server: header lines (if not | |
much else... This code is "somewhat" broken) like normal requests do. | |
[Martin Kraemer] | |
*) Be more smart in APACI's configure script when determining the UID/GID | |
for User/Group directives and use the determined UID/GID to initialize | |
the permissions on the proxycachedir. | |
[Dirk-Willem van Gulik, Ralf S. Engelschall] | |
*) Changed the forking-prior-to-cleanup in the proxy module to first | |
check wether it actually needs to collect garbage. This reduces | |
the number of fork()s from one/request to just the odd one an hour. | |
[Dirk-Willem van Gulik] | |

*) In configure, do not append the target name to the directory path if | |

*) SIGPIPE is now ignored by the server core. The request write routines | |
(ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now | |
correctly check for output errors and mark the connection as aborted. | |
Replaced many direct (unchecked) calls to ap_b* routines with the | |
analogous ap_r* calls. [Roy Fielding] | |
*) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and | |
DBM format mapfiles now uses a 4-way hash table with LRU functionality. | |
Furthermore map lookups for non-existent keys are now cached as well. | |
Additionally "txt" maps are now parsed with simple string functions | |
instead of using ap_pregcomp(). As a side effect a bug that prevented | |
the usage of keys containing the "," character was fixed. | |
The changes drastically improve the performance when large rewrite maps | |
are in use. | |
[Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160 | |

*) Allow apache acting as a proxy server to relay the real | |
reason of a failure to a client rather than the "internal | |
server error" it does currently. The general exposure mechanism | |
can be triggered by any module by setting the "verbose-error-to" | |
note to "*"; this allows more than just proxy errors to be exposed. | |
[Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086 | |

strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez] | |
*) Tweak modules Makefile generated by Configure so that it handles | |
the test case of no modules being selected. [<chaz reliant.com>] | |
*) Added a <LimitExcept method ...> sectioning directive that allows | |
the user to assign authentication control to any HTTP method that | |
is *not* given in the argument list; i.e., the logical negation | |
of the <Limit> directive. This is particularly useful for controlling | |
access on methods unknown to the Apache core, but perhaps known by | |
some module or CGI script. [Roy Fielding, Tony Finch] | |
*) Prevent apachectl from complaining if the PIDFILE exists but | |
does not contain a process id, as might occur if the server is | |
being rapidly restarted. [Wilfredo Sanchez] | |
*) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen] | |

*) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item() | |
to util.c for parsing an HTTP header field value to extract the next | |
list item, taking into account the possible presence of nested comments, | |
quoted-pairs, and quoted-strings. ap_get_list_item() also removes | |
insignificant whitespace and lowercases non-quoted tokens. | |
[Roy Fielding] PR#2065 | |
*) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status | |
code different from 500. This allows the proxy to, e.g., return | |
"403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455 | |
*) Fix ordering of language variants for the case where the traditional | |
negotiation algorithm is being used with multiple language variants | |
and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688 | |
*) Do not round the TCN quality calculation to 5 decimal places, | |
unlike RFC 2296, because the calculation might need 12 decimal places | |
to get the right result. [Roy Fielding] | |
*) Remove unused code to disable transparent negotiation when | |
negotiating on encoding only, as we now handle encoding too | |
(though this is nonstandard for TCN), remove charset=ISO-8859-1 | |
fiddle from the fiddle-averse RVSA comparison, and fix bugs in | |
some debugging statements within mod_negotiation. [Koen Holtman] | |
*) Fixed a rare memory corruption possibility in mod_dir if the index | |
file is negotiable and no acceptable variant can be found. | |
[Dean Gaudet, Roy Fielding, Martin Kraemer] | |
*) Win32: Add new config directive, ScriptInterpreterSource, to enable | |
searching the Win32 registry for script interpreters. | |
[Bill Stoddard] | |
*) Win32: The compiled-in default filename for the error log is now | |
error.log, which matches the default in the distributed httpd.conf. | |
[Paul Sutton] | |
*) Win32: Any error messages from -i or -u command line options are now | |
displayed on the console output rather than sent to the error log. | |
Also the "Running Apache..." message is not output unless Apache is | |
going to serve requests. [Paul Sutton] | |
*) Rework the MD5 authentication scheme to use FreeBSD's algorithm, | |
and use a private significator ('$apr1$') to mark passwords as | |
being smashed with our own algorithm. Also abstract the password | |
checking into a new ap_validate_password() routine. [Ken Coar] | |
*) Win32: The filename validity checker now allows "COM" but refuses | |
access to "COM1" through "COM4". This allows filenames such | |
as "com.name" to be served. [Paul Sutton] PR#3769. | |
*) BS2000: Adapt to the new ufork() system call interface which will | |
make subtasking easier on the OSD/POSIX mainframe environment. | |

[Jim Jagielski] PR#3671 | |
*) A consistent and conservative style for all shell scripts has been | |
implemented. Basically, all shell string tests use the traditional | |
hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]' | |
to protect against bare null variable strings (ie: wrapping both | |
sides with double quotes and prepending 'x'). 'x' was chosen | |
because it's more universal and hopefully easier for old shell | |
prgrammers, as well as being easier to search for in 'vi' (/x\$) :) | |
[Jim Jagielski] | |
*) The status module now prints out both the main server generation as | |
well as the generation of each process. Also, the vhost info is | |
printed with '?notable'. [Jim Jagielski] | |
*) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral | |

mostly for aesthetic reasons. [Roy Fielding] | |
*) The query switch "httpd -S" didn't exit after showing the | |
vhost settings. That was inconsistent with the other query functions. | |
[Martin Kraemer] | |
*) Moved the MODULE_MAGIC_COOKIE from before the versions and | |
filename to the end of the STANDARD_MODULE_STUFF. Its | |
presence at the beginning prevented reporting of the filename | |
for modules compiled before 1 January 1999. [Ken Coar] | |

*) IndexOptions SuppressColumnSorting only turned off making | |
the column headers anchors; you could still change the display | |
order by manually adding a '?N=A' or similar query string to the | |
URL. Now SuppressColumnSorting locks in the sort order so | |
it can't be overridden this way. [Ken Coar] | |

*) Instead of fixing a bug in the generation procedure for config.status (a | |
backslash was missing) we remove the bug together with it's complete | |
context because the special cases of the past can now no longer occur | |
because of the recent magic for the --with-layout default. | |
[Ralf S. Engelschall] PR#3590 | |
*) Make top-level Makefile aware of a parallel build procedures (make -j) by | |
making sure the src/support/ tools are _forced_ to be build last (they | |
depend on other libraries). | |
[Markus Theissinger <markus.theissinger gmx.de>] | |
*) Fix installation procedure: Now that os-inline.c is actually used (a | |
recently fixed bug prevented this) we need to also install os-include.c | |
in addition to os.h into the PREFIX/include/ location or building of | |
module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527 | |
*) Added MODULE_MAGIC_COOKIE as the first field in a module structure to | |
allow us to distinguish between a garbled DSO (or even a file which isn't | |
an Apache module DSO at all) and a DSO which doesn't match the current | |
Apache API. [Ralf S. Engelschall] PR#3152 | |
*) Two minor enhancements to mod_rewrite: First RewriteRule now also | |
supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to | |
match case insensitive (this especially avoids nasty patterns like | |
`[tT][eE][sS][tT]'). Second two additional internal map functions | |
`escape' and `unescape' were added which can be used to escape/unescape | |
to/from hex-encodings in URLs parts (this is especially useful in | |
combination with map lookups). | |
[Magnus Bodin, Ian Kallen, Ralf S. Engelschall] | |
*) Renamed the macro escape_uri() to ap_escape_uri() which was | |
forgotten (because it was a macro) in the symbol renaming process. | |
[Ralf S. Engelschall] | |
*) Fix some inconsistencies related to the scopes of directives. The only | |
user visible change is that the directives `UseCanonicalName' and | |
`ContentDigest' now use the (more correct) `Options' scope instead of | |
(less correct) `AuthConfig' scope. [Ralf S. Engelschall] | |
*) Using DSO, the Server token was being mangled. Specifically, the | |
module's token was being added first before the Apache token. This | |
has been fixed. [Jim Jagielski] | |
*) Major overhaul of mod_negotiation.c, part 2. | |
- properly handle "identity" within Accept-Encoding. | |
- allow encoded variants in RVSA negotiation and let them appear in | |
the Alternates field using the non-standard "encoding" tag-list. | |
- fixed both negotiation algorithms so that an explicitly accepted | |
encoding is preferred over no encoding if "identity" is not | |
included within Accept-Encoding. | |
- added ap_array_pstrcat() to alloc.c for efficient concatenation | |
of large substring sequences. | |
- replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat. | |
[Roy Fielding] | |
*) Major overhaul of mod_negotiation.c, part 1. | |
- cleanups to mod_negotiation comments and code structure | |
- made compliant with HTTP/1.1 proposed standard (rfc2068) and added | |
support for everything in the upcoming HTTP/1.1 | |
revision (draft-ietf-http-v11-spec-rev-06.txt). | |
- language tag matching also handles tags with more than 2 | |
levels like x-y-z | |
- empty Accept, Accept-Language, Accept-Charset headers are | |
processed correctly; previously an empty header would make all | |
values acceptable instead of unacceptable. | |
- allowed for q values in Accept-Encoding | |
- added support for transparent content negotiation (rfc2295 and | |
rfc2296) (though we do not implement all features in these drafts, | |
e.g. no feature negotiation). Removed old experimental version. | |
- implemented 'structured entity tags' for better cache correctness | |
(structured entity tags ensure that caches which can deal with Vary | |
will (eventually) be updated if the set of variants on the server | |
is changed) | |
- this involved adding a vlist_validator element to request_rec | |
- this involved adding the ap_make_etag() function to the global API | |
- modified guessing of charsets used by Apache negotiation algorithm | |
to guess 'no charset' if the variant is not a text/* type | |
- added code to sort multiviews variants into a canonical order so that | |
negotiation results are consistent across backup/restores and mirrors | |
- removed possibility of a type map file resolving to another type map | |
file as its best variant | |

*) The hashbang emulation code in ap_execve.c would interpret | |
#!/hashbang/scripts correctly, but failed to fall back to a | |
standard shell for scripts which did NOT start with #! | |
Now SHELL_PATH is started in these cases. [Martin Kraemer] | |
*) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>] | |
PR#3336 | |
*) Update APXS manual page: some -q option arguments were missing | |
and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553 | |
*) Cleanup the command line options: `-?' was documented to show | |
the usage list but does it with an error because `?' is not a valid | |
command. OTOH a lot of users expect `-h' to print such a usage list and | |
instead are annoyed for ages by our huge unreadable list of directives. | |
So we now changed the command line options this way: | |
1. `-L' => `-R' | |
Intent: we need `-L' to be free, and `-R' for the DSO run-time path is | |
very similar to the popular linker option. | |
2. `-h' => `-L' | |
Intent: while -l gives the small list of modules, -L now gives the | |
large list of directives implemented by these modules. This is also | |
consistent with -v (short version info) and -V (large version info). | |
3. `-?' => `-h' | |
Intent: it's now the expected option ;-) | |
The manual page was adjusted accordingly. | |
[Ralf S. Engelschall] PR#2714 | |
*) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC | |
wasn't defined. [Rick Franchuk <rickf transpect.net>] | |
*) Removed recently introduced bugs and disfigurements in APACI: | |
o fixed argument line processing: using $args was broken: It was not | |
initialized and using args="$args $apc_option" and even args="$args | |
\"$apc_option\"" fails in the second processing round for any arguments | |
containing whitespaces. The only correct way is to use the construct | |
"$@" (but not possible here) or iterate _both_ times over the implicit | |
argument line (no argument to for-loop) which is what we now use. | |
o make --with-layout=Apache the default without creating | |
redundancy (copying the --with-layout block in the argument parsing | |
loop). We achieve this by using the "$@" construct together with the | |
`set' command to prepend --with-layout=Apache to the command line in | |
case --with-layout is not used. | |
o fixed auto-suffix handling now that config.layout exists. | |
Paths which are auto-suffixed are marked with a trailing plus sign in | |
config.layout and every path now can be marked this way (not only the | |
four paths for which we do it currently). Additionally the suffix is | |
no longer a static one. Instead it's now `/<target>' where <target> is | |
the argument of the --target option or per default `httpd'. | |
o allow also tabs (and only spaces) where we match whitespaces | |
o various fixes and cleanups related to used shell coding style | |
o made Jim happy by replacing `Written by' with `Initially written by' ;-) | |
o trimmed output of --help to fit into 80 columns | |
[Ralf S. Engelschall] | |

[Ralf S. Engelschall] PR#3240 | |
*) Add APACI --shadow=DIR variant (in addition to --shadow). This now first | |
creates an external package shadow tree in DIR before the local build | |
shadow tree is generated under DIR. This way one can have the extracted | |

from these sources. An automatically triggered VPATH-like mechanism is | |
provided through the TOP variable, too. | |

The config.layout file consists of <Layout ID>..</Layout> sections | |
where inside those sections "path_variable: path_value" pairs can be | |
specified. These lines are converted to path_variable='path_value'. | |
*) Add a DefaultLanguage directive so that files missing a language | |

default language. DefaultLanguage can appear in <Directory> and | |
<Files> containers as well as .htaccess files. [Paul Sutton] | |

mod_foo with the begin of the module list, i.e. it `moves' the module to | |
the begin of the list (gives it lowest priority). And second foo:END | |
which permutes mod_foo with the end of the module list, i.e. it `moves' | |

instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this | |
platform to make the braindead HPUX linker happy. Notice, for the module | |
DSOs we don't have to use this, because these are loaded manually (and | |
not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968 | |
*) Remove 64 thread limit on Win32. | |
[Bill Stoddard <stoddard raleigh.ibm.com>] | |

[Ralf S. Engelschall] | |
*) Fix APACI's `Group' configuration adjustment - especially for Linux | |
platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall] | |
*) Make PrintPath work generically instead of having one version | |
strictly for OS/2. [Jim Jagielski, Brian Havard] | |
*) Fix the recently introduced C header file checking: We now use the C | |
pre-processor pass only (and no longer the complete compiler pass) to | |
determine whether a C header file exists or not. Because only this way | |
we're safe against inter-header dependencies (which caused horrible | |
portability problems). The only drawback is that we now have a CPP | |
configuration variable which has to be determined first (we do a similar | |
approach as GNU Autoconf does here). When all fails the user still has | |
the possibility to override it manually via APACI or src/Configuration. | |
As a fallback for the header check itself we can directly check the | |
existance of the file under /usr/include, too. | |
[Ralf S. Engelschall] PR#2777 | |
*) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined | |
as an alternate mechanism for mmap'd shared memory for RHAPSODY. | |

*) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1) | |
platform, because it's only supported under version 4.0 and higher. But | |
because our GuessOS is still unaware of Digital UNIX versions and the | |
-msym is just to optimize the DSO statup time a little bit it's safe and | |
best when we leave it out now. [Ralf S. Engelschall] PR#2969 | |
*) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf() | |
functions: First all three functions no longer fail on strings containing | |
"%" chars and second ap_log_printf() no longer does a double-formatting | |
(instead it directly passes through the message to be formatted to the | |
real internal formatting function). [Ralf S. Engelschall] PR#2941 | |
*) Allow "Include" directives anywhere in the server config | |
files (but not .htaccess files). [Ken Coar] PR#2727 | |
*) The proxy was refusing to serve CONNECT requests except to | |
port 443 (https://) and 563 (snews://). The new AllowCONNECT | |
directive allows the configuration of the ports to which a | |
CONNECT is allowed. [Sameer Parekh, Martin Kraemer] | |
*) mod_expires will now act on content that is not sent from a file | |
on disk. Previously it would never add an Expires: header to | |
any response that did not come from a file on disk; the only | |
case where it still doesn't (and can't) add one for that type of | |
content is if you are using a modification date based setting. | |
[Marc Slemko, Paul Phillips <paulp go2net.com>] | |
*) Problems encountered during .htaccess parsing or CGI execution | |
that lead to a "500 Server Error" condition now provide explanatory | |
text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts. | |
[Ken Coar] PR#1291 | |
*) Add NameWidth keyword to IndexOptions directive so that the | |
width of the filename column is customisable. [Ken Coar, Dean Gaudet] | |
PR#1949, 2324. | |
*) Recognize lowercase _and_ uppercase `uname' results under | |
SCO OpenServer. [David Coelho <drc ppt.com>] | |
*) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be | |
a common problem of (mis-administrated?) IIS servers, make the apache | |
proxy immune to these errors (and ignore the duplicates, but log | |
the fact to error_log). [Martin Kraemer], after the proposal in PR#2914 | |
*) The <IfModule and <IfDefine block starting directives now only | |
allow exactly one argument. Previously, the optional negation | |
character '!' could be separated by whitespace without a syntax | |
error being reported, albeit defeating the IfModule functionality | |
(enclosed directives would ALWAYS be executed). By using the | |
stricter syntax, these hard-to-track errors can be avoided. | |
[Martin Kraemer] | |
*) Simplify handling of IndexOptions in mod_autoindex -- and BTW | |
cause the standalone FancyIndexing directive to logically OR | |
into any existing IndexOptions settings rather than wiping | |
them out. [Ken Coar] | |
*) Changes in ftp proxy: make URL parsing simpler by using the | |
parsed_uri stuff. | |
+ Add display of the "current directory" in cases where it's | |
different from the supplied path (e.g., ftp://user@host/ lives | |
in /home/user, not in /, therefore clicking on "../" in the | |
starting directory might send us to /home/). | |
+ When ftp login fails, (esp. when a user name was part of the | |
URL already), we now return [401 Unauthorized ] to allow the | |
browser to pop up an authorization dialog. This makes passwords | |
slightly less visible (they don't appear in the regular log files) | |
and implements a functionality that other www proxy servers | |
already offered. | |
[Martin Kraemer] | |
*) Triggered by the recent "Via:" header changes, the proxy module would | |
dump core for replies with invalid headers (e.g., duplicate | |
"HTTP/1.0 200 OK" lines). These errors are now logged and the | |
core dump is avoided. Also, broken replies are not cached. | |
[Martin Kraemer] PR#2914 | |
*) new `GprofDir' directive when compiled with -DGPROF, where gprof can | |
plop gmon.out profile data for each child [Doug MacEachern] | |
*) Use the construct ``"$@"'' instead of ``$*'' in the generated | |
config.status script to be immune against arguments with whitespaces. | |
[Yves Arrouye <yves apple.com>] PR#2866 | |
*) Replace the inlined information grabbing stuff for the configuration | |
adjustment feature (no --without-confadjust) with calls to a new helper | |
script `buildinfo.sh' which is both more flexible and already proofed to | |
be more robust against platform differences. This mainly fixes the | |
recently occured ``sed: command garbled: ...'' problems. | |
[Ralf S. Engelschall] PR#2776, PR#2848 | |
*) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align | |
-Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline'' | |
without complains after we recently added the POST feature. | |
[Ralf S. Engelschall] | |
*) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside | |
modules as API functions and we forgot them at the big symbol renaming. | |

[Kurt Sussman <kls best.com>] PR#2871 | |
*) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of | |
5 to 10 because there are some users out there who always have 5 to 8 | |
variables in one RewriteRule and had to patch mod_rewrite.h for every | |
release. So 15 should be now more than enough, even for them. (I never | |
needed more than 4 in my RewriteRules ;-) | |
[Ralf S. Engelschall] | |
*) Make the proxy generate and understand Via: headers | |
[Martin Kraemer] | |
*) Change the proxy to use tables instead of array_headers for | |
the header lines. [Martin Kraemer] | |
*) Make sure the config.status file is not overridden when just | |
``configure --help'' is used. [Ralf S. Engelschall] PR#2844 | |
*) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should | |
provide a way to trace API changes that add functionality but do | |
not create a compatibility issue for precompiled modules, etc. | |
See include/ap_mmn.h for more details. [Randy Terbush] | |
*) Fix suexec installation under `make install root=xxx' situation. | |
[Ralf S. Engelschall] | |
*) Extend the output of the -V switch to include the paths of all | |

compile time, for least astonishment of the user. | |
[Martin Kraemer] | |
*) When READing a request in ExtendedStatus mode, the "old" | |
vhost, request and client information is not displayed. | |
[Jim Jagielski] | |
*) STATUS is no longer available. Full status information now | |
run-time configurable using the ExtendedStatus directive. | |
[Jim Jagielski] | |
*) SECURITY [CAN-1999-1199] (cve.mitre.org): | |
Eliminate O(n^2) space DoS attacks (and other O(n^2) | |
cpu time attacks) in header parsing. Add ap_overlap_tables(), | |
a function which can be used to perform bulk update operations | |
on tables in a more efficient manner. | |
[Dean Gaudet] | |
*) SECURITY: Added compile-time and configurable limits for | |
various aspects of reading a client request to avoid some simple | |
denial of service attacks, including limits on maximum request-line | |
size (LimitRequestLine), number of header fields (LimitRequestFields), | |
and size of any one header field (LimitRequestFieldsize). Also added | |
a configurable directive LimitRequestBody for limiting the size of the | |
request message body. [Roy Fielding] | |
*) Make status module aware of DNS and logging states, even if | |
STATUS not defined. [Jim Jagielski] | |
*) Fix a problem with the new OS/2 mutexes. [Brian Havard] | |

ap_scan_script_header_err_core() [Doug MacEachern] | |
*) The 'status' module will now show the process pid's and their | |
state even without full STATUS accounting. [Jim Jagielski] | |
*) Restore the client IP address to the error log messages, this | |
was lost during the transition from 1.2 to 1.3. Add a new | |
function ap_log_rerror() which takes a request_rec * and | |
formats it appropriately. [Dean Gaudet] PR#2661 | |
*) Cure ap_cfg_getline() of its nasty habit of compressing internal | |
whitespace in input lines -- including within quoted strings. | |
[Ken Coar] | |
but leading and trailing whitespace should continue to be | |
stripped [Martin Kraemer] | |
*) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid | |
the ugly use of an env. variable and use command-line args for | |
alternate $PATH. Make more like advanced 'type's as well. | |
[Jim Jagielski] | |

*) Clean up a warning in mod_proxy. [Ralf S. Engelschall] | |
*) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2 | |
following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/ | |
directory was renamed to src/os/os2/ for consistency. | |
[Brian Havard, Ralf S. Engelschall] | |
*) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO | |
files (here modules) against other DSO files (here shared libraries). | |
This is done by determining a subset of LIBS which can be safely used for | |
linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is | |
disabled for all platforms to avoid problems with this (experimental) | |
rule. But we provide it now for those people how ran into problems and | |
want to came out by forcing linking against DSOs. | |
[Ralf S. Engelschall] PR#2587 | |

*) One more portability fix for APACI shadow tree support: Swap order of awk | |

*) Fixed problem with buffered response message not being sent for | |
the read_request error conditions of URI-too-long (414) and | |

*) Add support for the Max-Forwards: header line required by RFC2068 for | |
the TRACE method. This allows apache to TRACE along a chain of proxies | |
up to a predetermined depth. [Martin Kraemer] | |

*) WIN32: Canonicalize ServerRoot before checking to see if it | |
is a valid directory. The failure to do this caused certain | |
ServerRoot settings (eg. "ServerRoot /apache") to be improperly | |
rejected. [Marc Slemko] | |
*) Global renaming of C header files to both get rid of conflicts with third | |
party packages and to again reach consistency: | |
1. conf.h -> ap_config.h | |
2. conf_auto.h -> ap_config_auto.h \ these are now merged | |
3. ap_config.h -> ap_config_auto.h / in the config process | |
4. compat.h -> ap_compat.h | |
5. apctype.h -> ap_ctype.h | |
Backward compatibility files for conf.h and compat.h were created. | |
*) mod_mmap_static will no longer take action on requests unless at | |
least one "mmapfile" directive is present in the configuration. | |
This experimental module has to do some black magic to operate | |
inside the current API and thus creates side-effects for other | |
modules under some circumstances. | |

if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341 | |
*) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via | |
TestCompile) instead of defining them manually in conf.h based on less | |
accurate platform definitions. This way we no longer have to fiddle with | |
OS-type and/or OS-version identifiers to discover whether a system header | |

*) Portability fix for APACI shadow tree support: Swap order of awk and sed | |
in top-level configure script to avoid sed fails on some platforms (for | |
instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined | |
output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435 | |
*) Improve performance of directory listings (mod_autoindex) by comparing | |
integer keys (last-modified and size) as integers rather than converting | |
them to strings first. Also use a set of explicit byte tests rather | |
than strcmp() to check for parent directory-ness of an entry. Oh, and | |
make sure the parent directory (if displayed) is *always* listed first | |
regardless of the sort key. Overall performance winnage should be good | |
in CPU time, instruction cache, and memory usage, particularly for large | |
directories. [Ken Coar] | |
*) Add a tiny but useful goody to APACI's configure script: The generation | |
of a config.status script (as GNU Autoconf does) which remembers the used | |
configure command and hence can be used to restore the configuration by | |
just re-running this script or for remembering the configuration between | |
releases. | |
[Ralf S. Engelschall] | |
*) Add httpd -t (test) option for running configuration syntax tests only. | |
If something is broken it complains and exits with a return code | |
non-equal to 0. This can be used manually by the user to check the Apache | |
configuration after editing and is also automatically used by apachectl | |
on (graceful) restart command to make sure Apache doesn't die on restarts | |
because of a configuration which is now broken since the last (re)start. | |
This way `apachectl restart' can be used inside cronjobs without having | |
to expect Apache to be falling down. Additionally the httpd -t can be run | |
via `apachectl configtest'. | |

*) Upgrade the child spawning code in mod_rewrite for the RewriteMap | |

[Ralf S. Engelschall] | |
*) A few cosmetics and trivial enhancements to APXS to make the | |

*) Proxy Fix: The proxy special failure routine ap_proxyerror() | |
was updated to use the normal apache error processing, thereby allowing | |
proxy errors to be treated by ErrorDocument's as well. For this | |
purpose, a new module-to-core communication variable "error-notes" | |
was introduced; the proxy (and possibly other modules) communicates | |
its error text using this variable. Its content is copied to a new | |
cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments. | |
The old proxy special error routine ap_proxy_log_uerror() | |
was replaced by regular ap_log_error() calls, many messages were made | |
more informative. | |
[Martin Kraemer] PR#494, 1259 | |
*) SECURITY: A possible buffer overflow in the ftp proxy was fixed. | |
[Martin Kraemer] | |
*) Transform the configure message "You need root privileges for suEXEC" | |

only for the installation step ("make install"). So make sure the | |
user is aware of this fact but let him proceed as long as he can. | |
[Ralf S. Engelschall] PR#2288 | |

*) Make sure a MIME-type can be forced via a RewriteRule even when no | |
substitution takes place, for instance via the following rule: | |
``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often | |
requested by users in the past to force a single script without a .cgi | |

*) The proxy cache would store an incorrect content-length in the cached | |

of the original copy instead of using the cached copy. | |
[Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094 | |
*) The Makefiles assumed that DSO files are build via $(LD). This | |
is broken for two reasons: First we never defined at least LD=ld | |
somewhere to make sure this works (it was silently assumed that most Make | |
provide a built-in LD definition - ARGL!) and second using the generic LD | |
variable is not the truth. Instead a special variable named LD_SHLIB is | |
reasonable because although "ld" is usually the default, the command for | |
building DSO files can be "libtool" or even "cc" on some systems. | |
[Ralf S. Engelschall] | |
*) Replace the AddVersionPlatform directive with ServerTokens which | |
provides for more control over the format of the Server: | |
header line. SERVER_SUBVERSION is no longer supported; | |
all module should use the ap_add_version_component() | |
API function instead. [Jim Jagielski] | |
*) Support for the NCR MP/RAS 3.0 | |
[John Withers <withers semi.kcsc.mwr.irs.gov>] | |
*) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was | |
not retrieved in src/Configure and thus was not useable. | |
[Ralf S. Engelschall] | |
*) Various Makefile consistency cleanups: | |
- make OSDIR also automatically be relative to src/ like INCDIR | |
- SUBDIRS is now generated in src/Makefile only and not in | |
Makefile.config because it is a local define for this location. | |
- remove BROKEN_BPRINTF_FLAGS because is it no longer used inside | |
any Makefile but make sure that at least the "-K inline" is kept in | |
CFLAGS for SCO 5. | |
- update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too. | |
- updated the dependencies theirself | |
- removed not existing SHLIB variable from "clean" targets | |
- replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS | |
already exists and OBJS_PIC are also just plain objects and have not | |
directly to do with "shared" things. The only difference is that they | |
contain PIC. So OBJS_PIC is the more canonical name. | |
- Updated the Makefile-dependency lines for OBJS_PIC | |
- Removed the Makefile-dependency line in Configure to avoid double | |
definitions | |
- replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage | |
of xxx.lo as GNU libtool does with its PIC objects | |
- reduce local complexity in modules Makefile.tmpl by moving the last | |
existing target "depend" to the generation section in Configure, too. | |
- removed the historical $(SPACER) which was used in the past together | |
with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This | |
is no longer needed. | |
- force the build and run of the gen_xxx programs under main/ as the | |
first step before building the objects because it looks cleaner | |

[Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060 | |
*) When opening "configuration" files (like httpd.conf, htaccess | |
and htpasswd), Apache will not allow them to be non-/dev/null | |
device files. This closes a DoS hole. At the same time, | |
we use ap_pfopen to open these files to handle timeouts. | |
[Jim Jagielski, Martin Kraemer] | |
*) Apache will now log the reason its httpd children exit if they exit | |
due to an unexpected signal. (It requires a new porting define, | |
SYS_SIGLIST, which if defined should point to a list of text | |
descriptions of the signals available. See PORTING.) [Dean Gaudet] | |
*) WIN32: chdir() doesn't make sense in a multithreaded environment | |
like WIN32. Before, Win32 CGI's could have had sporadic failures | |
if a chdir call from one thread was made between another chdir call | |
and a spawn in another thread. So, for now don't chdir for CGI scripts | |
in WIN32. The current CGI "spec" is unclear as to whether it's | |
necessary. Long-term fix is to either serialize the chdir/spawn combo | |
or use WIN32 native calls to spawn a process. This temp fix was | |
necessary to remove this as a showstopper for 1.3's release. | |
[Brian Behlendorf] | |
*) Cleanup the suEXEC support in APACI and make it more safe: | |
1. Add big fat hint in INSTALL about risks and to read the | |
htdocs/manual/suexec.html document before using the suexec-related | |
configure options. | |
2. Make sure the user has at least provided one --suexec-xxxx option | |
(specifies suEXEC parameters) in addition to --enable-suexec option. | |
If only --enable-suexec is given APACI stops with a hint to INSTALL | |
and htdocs/manual/suexec.html documents. | |
3. Provide two additional --suexec-xxxx options to make the suEXEC | |
configuration complete (especially for package maintainers who else | |
had to patch the source tree) by providing ways to configure minimal | |
UID/GID and safe PATH, too. | |
[Ralf S. Engelschall] | |
*) Cleanup of the `configure --shadow' process: | |
- make sure the configure script creates its temporary files in the | |
shadow tree to avoid conflicts with parallel configure runs | |
- removed unnecessary option "-r" from "rm" call for Makefiles | |
- make sure the configure scripts creates the shadow-wrapper Makefile | |
only when no shadow trees already exists | |
- make sure "make distclean" removes the shadow-wrapper Makefile but only | |
when no more shadow trees exists | |
- overhauled mkshadow.sh script: now its more IFS-safe and approx. twice | |
as fast (in the past it needed 70sec, now it runs just 38sec) | |
- make sure CVS does not complain about the created files | |
Makefille.<gnutriple> and directories src.<gnutriple> | |
[Ralf S. Engelschall] | |
*) Added the ap_add_version_component() API routine and the | |
AddVersionPlatform core directive. The first allows modules to | |
declare themselves in the Server response header field value, | |
augmenting the SERVER_SUBVERSION define in the Configuration file | |
with run-time settings (more useful in a loadable-module environment). | |
AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)" | |
into the server version string. [Ken Coar] PR#2056 | |
*) Minor stability tweaks to avoid core dumps in ap_snprintf. | |
[Martin Kraemer] | |
*) Emit the "Accept-Range" header for the default handler. | |
[Brian Behlendorf] PR#1464 | |
*) Add a note to httpd.conf-dist that apache will on some systems fail | |
to start when the Group # is set to a negative or large positive value. | |
[Martin Kraemer] | |
*) Make sure the module execution order is correct even when some modules | |
are loaded under runtime (`LoadModule') via the DSO mechanism: | |
1. The list of loaded modules is now a dynamically allocated one | |
and not the original statically list from modules.c | |
2. The loaded modules are now correctly setup by LoadModule for | |
later use by the AddModule command. | |
3. When the DSO mechanism for modules is used APACI's `install' | |
target now enables all created `LoadModule' lines per default because | |
this is both already expected by the user _and_ needed to avoid | |
confusion with the next point and reduces the Makefile.tmpl complexity | |
4. When the DSO mechanism for modules is used, APACI's `install' | |
target now additionally makes sure the module list is reconstructed | |
via a complete `ClearModuleList+AddModule...' entry. | |
5. The support tool `apxs' now also makes sure an AddModule command | |
is added in addition to the LoadModule command. | |
6. The modules.c generation was extended to now contain two | |
comments to make sure no one is confused by the confusing terminology | |
of loading/linking (we use load=link+load & link=activate instead of | |
the obvious load=activate & link=link :-( ) | |
This way now there is no longer a difference under execution time between | |
statically and dynamically linked modules. | |
[Ralf S. Engelschall] | |
*) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the | |
Big Symbol Renaming. [Ralf S. Engelschall] | |

because if there's no Port directive in the config r->server->port is 0. | |

*) PORT: Dynamic Shared Object (DSO) support for NetBSD. | |
[Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158 | |
*) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older | |
AIX variants should work fine, too. Even AIX 3.x should work). This is | |
accomplished by using the free DSO emulation code from Jens-Uwe Mager | |
which we put into a os/unix/os-dso-aix.c file. | |

*) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO | |
is unset (as it is in situations like timeouts) where it is unclear | |
whether errno is set or not. [Martin Kraemer] | |
*) Just having APACI's localstatedir is too general and not enough for most | |
of the systems. 1.3b6 again required manual APACI patches by package | |
maintainers from Red Hat and FreeBSD because for their filesystem layout a | |
little bit more flexibility in configuring the paths is needed. Hence we | |
provide three additional configure options (--runtimedir, --logfiledir, | |
--proxycachedir) which now can be used for more granular adjustments if | |
--localstatedir is not enough to fit the particular needs. As a nice | |
side-effect this reduces some subdir fiddling in configure+Makefile.tmpl. | |
[Ralf S. Engelschall] | |
*) Make the install root for "make install" in APACI's Makefile overrideable | |
by package authors. This way we are even more friendly to package | |
maintainers (especially Debian and Red Hat) who build for the real prefix | |
via "configure --prefix=/<real>" but use a different local prefix via | |
"make root=/tmp/apache install" for rolling the package without bristling | |
the target location on their system. | |
[Ralf S. Engelschall] | |

*) ++++ THE BIG SYMBOL RENAMING ++++ | |
To avoid symbol clashes with third-party code compiled into the server, | |
we globally applied the prefix "ap_" to the following classes of | |
functions: | |
- Apache provided general functions (e.g., ap_cpystrn) | |
- Public API functions (e.g., palloc, bgets) | |
- Private functions which we can't make static (because of | |
cross-object usage) but should be (e.g., new_connection) | |
For backward source compatibility a new header file named compat.h was | |
created which provides defines for the old symbol names and can be used | |
by third-party module authors. | |
[The Apache Group] | |
*) Added dynamic shared object (DSO) support for SVR4-derivates: The | |
problem under SVR4 is that there is no command flag to force the linker | |
to export the global symbols of the httpd executable therewith they are | |
available to the DSO's. Instead of problematic hacks like creating a | |
dummy.so file (containing dummy references to all global symbols) the | |
httpd binary is linked against, we use a clean trick stolen from Perl 5: | |
Placing the Apache core code itself into a DSO library named libhttpd.so. | |
This way the global symbols _HAVE_ to be exported and thus are available | |
to any manually loaded DSO's under runtime. To reduce the impact to the | |
user to null we go even further and create a stub httpd executable which | |
automatically keeps track of the DSO library loading itself and thus | |
hides the complete mechanism from the user. Although the generation of | |
this DSO library is automatically triggered for platforms which | |
essentially need it (mostly all SVR4-derivates) it can be also enabled | |
manually via the Rule SHARED_CORE. This can be interesting in the future | |
where we perhaps exploit this libhttpd.so mechanism for providing nifty | |
features like graceful upgrades, or whatever. | |
[Ralf S. Engelschall, Martin Kraemer] | |
*) Build the libraries before building the rest of the tools. [Ben Hyde] | |
*) Add "distclean" target to src/-Makefiles to provide "make distclean" also | |
inside the src subtree (i.e. for non-APACI users). Following GNU Makefile | |
conventions while "clean" removes only stuff created by "all" targets, | |
"distclean" additionally removes the stuff from the configuration | |
process. This way "make distclean" (hence the name) provides a fresh | |
source tree as it was for distribution. | |
[Ralf S. Engelschall] | |
*) Allow top-level (APACI) Makefile to break on build errors | |
the same way the src/ subtree Makefiles breaks on them by replacing the | |
initial APACI sed-subdir-display-kludge with a more clean | |
variable-passing-solution: variable SDP can optionally hold the subdir | |
prefix which is consistently used for displaying the subdir movement. | |
This way even the top-level Makefile can stop correctly on errors as the | |
user expects. [Ralf S. Engelschall] | |
*) Fixed ordering of argument checks for RewriteBase directive. | |
[Todd Eigenschink <eigenstr mixi.net>] PR#2045 | |
*) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of | |
indicating that a module is being compiled for dynamic loading. Also | |
remove #define IS_MODULE from modules and add SHARED_MODULE define | |
to the mak/dsp files. [Alexei Kosut] | |
*) Reduce logging level of "normal" warning messages to APLOG_INFO, | |
since we are now logging APLOG_WARNING by default. [Roy Fielding] | |
*) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard] | |
*) Add documentation file and src/Configuration.tmpl entry for the | |
experimental mod_mmap_static module. Because although it is and marked as | |
an experimental one it is distributed and thus should be documented and | |
prepared for configuration the same way as all others modules. | |
[Ralf S. Engelschall] | |
*) Add query (-q) option to apxs support tool to be able to manually query | |
specific settings from apxs. This is needed for instance when you | |
manually want to access Apache's header files and you need to assemble | |
the -I option. Now you can do -I`apxs -q INCLUDEDIR`. | |
[Ralf S. Engelschall] | |
*) Now src/Configure uses a fallback strategy for the shared object support | |
on platforms where no explicit information is available: If a Perl | |
installation exists we ask it about its shared object support and if it's | |
the dlopen-style one we shamelessly guess the compiler and linker flags | |
for creating shared objects from Perls knowledge. Of course, the user is | |
warning about what we are doing and informed that he should send us | |
the guessed flags when they work. [Ralf S. Engelschall] | |
*) Provide APACI --without-support option to be able to disable the build | |
and installation of the support tools from the src/support/ area. | |
Although its useful to have these installed per default we should provide | |
a way to compile and install without them for backward-compatibility. | |
[Ralf S. Engelschall] | |
*) Add of the new APache eXtenSion (apxs) support tool for building and | |
installing modules into an _already installed_ Apache package through the | |
dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that | |
this approach actually doesn't need the Apache source tree. The | |
(APACI-installed) server package is enough, because this now includes the | |
Apache C header files (PREFIX/include) and the new APXS tool | |
(SBINDIR/apxs). The intend is to provide a handy tool for third-party | |
module authors to build their Apache modules _OUTSIDE_ the Apache source | |
tree while avoiding them to fiddle around with the totally platform | |
dependend way of compiling DSO files. The tool supports all ranges of | |
modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3 | |
which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can | |
on-the-fly generate a minimalistic Makefile and sample module for the | |
first step to provide both a quick success event and to demonstrate the | |
APXS mechanism to module authors. [Ralf S. Engelschall] | |
*) Fix core dumps in use of CONNECT in proxy. | |
[<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942 | |
*) Modify the log directives in httpd.conf-dist files to use CustomLog | |
so that users have examples of how CustomLog can be used. | |
[Lars Eilebrecht] | |
*) Add the new Apache Autoconf-style Interface (APACI) for the top-level of | |
the Apache distribution tree. Until Apache 1.3 there was no real | |
out-of-the-box batch-capable build and installation procedure for the | |
complete Apache package. This is now provided by a top-level "configure" | |
script and a corresponding top-level "Makefile.tmpl" file. The goal is | |
to provide a GNU Autoconf-style frontend which is capable to both drive | |
the old src/Configure stuff in batch and additionally installs the | |
package with a GNU-conforming directory layout. Any options from the old | |
configuration scheme are available plus a lot of new options for flexibly | |
customizing Apache. [Ralf S. Engelschall] | |
*) The floating point ap_snprintf code wasn't threadsafe. | |
Had to remove the HAVE_CVT macro in order to do threadsafe | |
calling of the ?cvt() floating point routines. [Dean Gaudet] | |

*) BUG: Configure was using TCC and CC inconsistently. Make sure | |
Configure knows which CC we are using. [Jim Jagielski] | |
*) "Options +Includes" wasn't correctly merged if "+IncludesNoExec" | |
was defined in a parent directory. [Lars Eilebrecht] | |
*) API: ap_snprintf() code mutated into ap_vformatter(), which is | |
a generic printf-style routine that can call arbitrary output | |
routines. Use this to replace http_bprintf.c. Add new routines | |
psprintf(), pvsprintf() which allocate the exact amount of memory | |
required for a string from a pool. Use psprintf() to clean up | |
various bits of code which used ap_snprintf()/pstrdup(). | |
[Dean Gaudet] | |
*) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because | |
ap_snprintf() has different semantics and formatting codes than | |
snprintf(). [Dean Gaudet] | |
*) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This | |
is necessary on at least Solaris where the /etc/rc?.d scripts | |
are run with these signals ignored, and "SIG_IGN" settings are | |
maintained across exec(). | |

*) Fix the proxy pass-through feature of mod_rewrite for the case of | |
existing QUERY_STRING now that mod_proxy was recently changed because of | |
the new URL parsing stuff. [Ralf S. Engelschall] | |
*) A few changes to scoreboard definitions which helps gcc generate | |

[Jürgen Keil <jk tools.de>] PR#2000 | |
*) Allow %2F in two situations: 1) it is in the query part of the URI, | |
therefore not exposed to %2F -> '/' translations and 2) the request | |
is a proxy request, so we're not dealing with a local resource anyway. | |
Without this, the proxy would fail to work for any URL's with | |
%2f in them (occurs quite often in | |
http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer] | |
*) Protect against FD_SETSIZE mismatches. [Dean Gaudet] | |
*) Make the shared object compilation command more portable by avoiding | |
the direct combination of `-c' & `-o' which is not honored by some | |

*) WIN32: the proxy was creating filenames missing the last four | |

[Tim Costello <tjcostel socs.uts.edu.au>] PR#1890 | |
*) Now mod_proxy uses the response string (in addition to the response status | |
code) from the already used FTP SIZE command to setup the Content-Length | |
header if available. [Ralf S. Engelschall] PR#1183 | |
*) Reanimated the (still undocumented) proxy receive buffer size directive: | |
Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old | |
name was really too generic, added documentation for this directive to | |
the mod_proxy.html and corrected the hyperlink to it in the | |
new_features_1.3.html document. [Ralf S. Engelschall] PR#1348 | |
*) Fix a bug in the src/helpers/fp2rp script and make it a little bit | |
faster [Martin Kraemer] | |
*) Make Configure die when you give it an unknown command switch. | |
[Ben Hyde] | |
*) Add five new and fresh manpages for the support programs: dbmmanage.1, | |
suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date | |
and per default compiled support programs have manual pages - just to | |
document our stuff a little bit more and to be able to do really | |
Unix-like installations ;-) [Ralf S. Engelschall] | |
*) Major cleanups to the Configure script to make it and its generated | |
Makefiles again readable and maintainable: add SRCDIR option, removed | |
INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of | |
generated sections, consequently added Makefile headers with inheritance | |
information, added subdir movement messages for easier following where | |
the build process currently stays (more verbose then standard Make, less | |
verbose than GNU make), same style to comments in the Configure script, | |
added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall] | |
*) Add the new ApacheBench program "ab" to src/support/: This is derived | |
from the ZeusBench benchmarking program and can be used to determine the | |
response performance of an Apache installation. This version is | |
officially licensed with Zeus Technology, Ltd. See the license agreement | |
statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core. | |
[Ralf S. Engelschall] | |
*) API: Various core functions that are definately not part of the API | |
have been made static, and a few have been marked API_EXPORT. Still | |
more have been marked CORE_EXPORT and are not intended for general | |
use by modules. [Doug MacEachern, Dean Gaudet] | |
*) mod_proxy was not clearing the Proxy-Connection header from | |
requests; now it does. This did not violate any spec, however | |
causes poor interactions when you are talking to remote proxies. | |

*) Performance tweak to mod_log_config. [Dmitry Khrustalev] | |
*) Clean up some undocumented behavior of mod_setenvif related to | |
"merging" two SetEnvIf directives when they match the same header | |
and regex. Document that mod_setenvif will perform comparisons in | |
the order they appear in the config file. Optimize mod_setenvif by | |
doing more work at config time rather than at runtime. | |
[Dean Gaudet] | |
*) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's | |
to allow for modules to overrule them and to reduce redefinition | |
warnings [Jim Jagielski] | |
*) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3. | |
[Jim Jagielski] | |
*) Making the hard-coded cross-module function call mime_find_ct() (from | |
mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type | |
checking is really called even for proxy requests except for URLs with | |
HTTP schemes (because there we can optimize by not running the type | |
checking hooks due to the fact that the proxy gets the MIME Content-type | |
from the remote host later). This change cleans up mod_mime by removing | |
the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and | |
especially unbundles mod_proxy and mod_mime. This way they both now can | |
be compiled as shared objects and are no longer tied together. | |
[Ralf S. Engelschall] | |
*) util.c cleanup and speedup. [Dean Gaudet] | |
*) API: Clarification, pstrndup() will always copy n bytes of the source | |
and NUL terminate at the (n+1)st byte. [Dean Gaudet] | |
*) Mark module command_rec and handler_rec structures const so that they | |
end up in the read-only data section (and are friendlier to systems | |
that don't do optimistic memory allocation on fork()). [Dean Gaudet] | |
*) Add check to the "Port" directive to make sure the specified | |
port is in the appropriate range. [Ben Hyde] | |
*) Performance improvements to invoke_handler(). | |
[Dmitry Khrustalev <dima bog.msu.su>] | |
*) Added support for building shared objects even for library-style modules | |
(which are built from more than one object file). This now provides the | |
ability to build mod_proxy as a shared object module. Additionally | |
modules like mod_example are now also supported for shared object | |
building because the generated Makefiles now no longer assume there is at | |
least one statically linked module. [Ralf S. Engelschall] | |
*) API: Clarify usage of content_type, handler, content_encoding, | |
content_language and content_languages fields in request_rec. They | |
must always be lowercased; and the strings pointed to shouldn't | |
be modified (you must copy them to modify them). Fix a few bugs | |
related to this. [Dean Gaudet] | |
*) API: Clarification: except for RAW_ARGS, all command handlers can | |
treat the char * parameters as permanent, and modifiable. There | |
is no need to pstrdup() them. Clean up some needless pstrdup(). | |
[Dean Gaudet] | |
*) Now mod_so keeps track of which module shared objects with which names | |
are loaded and thus avoids multiple loading and unloading and irritating | |
error_log messages. [Ralf S. Engelschall] | |
*) Prior to the existence of mod_setenv it was necessary to tweak the TZ | |
environment variable in the apache core. But that tweaking interferes | |
with mod_setenv. So don't tweak if the user has specified an explicit | |
TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888 | |

name, or left unset if this value is unavailable. Apache was setting | |
it to the IP address when unavailable. | |
[Tony Finch <fanf demon.net>] PR#1925 | |
*) Various improvements to the configuration and build support for compiling | |
modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and | |
OSF1 support with GCC and vendor compilers was added. This way shared | |
object support is now provided out-of-the-box for FreeBSD, Linux, | |
Solaris, SunOS, IRIX and OSF1. In short: On all major platforms! | |
[Ralf S. Engelschall] | |
*) Minor cleanup in http_main -- split QNX and OS2 specific "mmap" | |
scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD | |
and USE_OS2_SCOREBOARD. [Dean Gaudet] | |
*) Fix one more special locking problem for RewriteMap programs in | |
mod_rewrite: According to the documentation of flock(), "Locks are on | |
files, not file descriptors. That is, file descriptors duplicated | |
through dup(2) or fork(2) do not result in multiple instances of a lock, | |
but rather multiple references to a single lock. If a process holding a | |
lock on a file forks and the child explicitly unlocks the file, the | |
parent will lose its lock.". To overcome this we have to make sure the | |
RewriteLock file is opened _AFTER_ the childs were spawned which is now | |
the case by opening it in the child_init instead of the module_init API | |
hook. [Ralf S. Engelschall] PR#1029 | |
*) Change to Location and LocationMatch semantics. LocationMatch no | |
longer lets a single slash match multiple adjacent slashes in the | |
URL. This change is for consistency with RewriteRule and | |
AliasMatch. Multiple slashes have meaning in URLs that they do | |
not have in (some) filesystems. Location on the other hand can | |
be considered a shorthand for a more complicated regex, and it | |
does match multiple slashes with a single slash -- which is | |
also consistent with the Alias directive. | |

of length 0, to result in no response from the server. | |
[Dean Gaudet] | |
*) The Configure script now generates src/include/ap_config.h which | |
contains the set of defines used when Apache is compiled on a platform. | |
This file can then be included by external modules before including | |
any Apache header files in case they are being built separately from | |
Apache. Along with this change, a couple of minor changes were | |
made to make Apache's #defines coexist peacefully with any autoconf | |
defines an external module might have. [Rasmus Lerdorf] | |
*) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist | |
but without any RewriteXXXXX directives. Here mod_rewrite is given no | |
chance by the API to initialize its per-server configuration and thus | |
receives the wrong one from the main server. This is now avoided by | |
remembering the server together with the config structure while | |
configuring and later assuming there is no config when we see a | |
difference between the remembered server and the one calling us. | |
[Ralf S. Engelschall] PR#1790 | |
*) Fixed the DBM RewriteMap support for mod_rewrite: First the support now | |
is automatically disabled under configure time when the dbm_xxx functions | |
are not available. Second, two heavy source code errors in the DBM | |
support code were fixed. This makes DBM RewriteMap's usable again after | |
a long time of brokenness. [Ralf S. Engelschall] PR#1696 | |
*) Now all configuration files support Unix-style line-continuation via | |
the trailing backslash ("\") character. This enables us to write down | |

*) mod_test_util_uri.c created which tests the logic in util_uri.c. | |
[Dean Gaudet] | |
*) API: Rewrite of absoluteURI handling, and in particular how | |
absoluteURIs match vhosts. Unless a request is a proxy request, a | |
"http://host" url is treated as if a similar "Host:" header had been | |
supplied. This change was made to support future HTTP/1.x protocols | |
which may require clients to send absoluteURIs for all requests. | |
In order to achieve this change subtle changes were made to the API. In a | |
request_rec, r->hostlen has been removed. r->unparsed_uri now exists so | |
that the unmodified uri can be retrieved easily. r->proxyreq is not set | |
by the core, modules must set it during the post_read_request or | |
translate_names phase. | |
Plus changes to the virtualhost test suite for absoluteURI testing. | |

managed by the same httpd. | |

*) API: A new source module main/util_uri.c; It contains a routine | |
parse_uri_components() and friends which breaks a URI into its component | |
parts. These parts are stored in a uri_components structure called | |
parsed_uri within each request_rec, and are available to all modules. | |
Additionally, an unparse routine is supplied which re-assembles the URI | |
components back to an URI, optionally hiding the username:password@ part | |
from ftp proxy requests, and other useful routines. Within the structure, | |
you find on a ready-for-use basis: | |
scheme; /* scheme ("http"/"ftp"/...) */ | |
hostinfo; /* combined [user[:password]@]host[:port] */ | |
user; /* user name, as in http://user:passwd@host:port/ */ | |
password; /* password, as in http://user:passwd@host:port/ */ | |
hostname; /* hostname from URI (or from Host: header) */ | |
port_str; /* port string (integer representation is in "port") */ | |
path; /* the request path (or "/" if only scheme://host was given) */ | |
query; /* Everything after a '?' in the path, if present */ | |
fragment; /* Trailing "#fragment" string, if present */ | |
This is meant to serve as the platform for *BIG* savings in | |
code complexity for the proxy module (and maybe the vhost logic). | |
[Martin Kraemer] | |
*) Make all possible meta-construct expansions ($N, %N, %{NAME} and | |
${map:key}) available for all location where a string is created in | |

type but with a special post-processing for the looked-up value: It | |
parses it into alternatives according to `|' chars and then only one | |
particular alternative is chosen randomly (this is an essential | |
functionality needed for balancing between backend-servers when using | |
Apache as a Reverse Proxy. The looked up value here is a list of | |
servers). Second, `int' with the built-in maps named `tolower' and | |
`toupper' which can be used to map URL parts to a fixed case (this is an | |
essential feature to fix the case of server names when doing mass | |
virtual-hosting with the help of mod_rewrite instead of using | |
<VirtualHost> sections). [Ralf S. Engelschall, parts based on code from | |

get_server_port(). | |
[Michael Douglass <mikedoug texas.net>, Dean Gaudet] | |
PR#315, 459, 485, 1433 | |
*) Yet another rearrangement of the source tree.. now all the common | |
header files are in the src/include directory. The -Imain -Iap | |
references in Makefiles have been changed to the simpler -Iinclude | |
instead. In addition to simplifying the build a little bit, this | |
also makes it clear when a module is referencing something in a | |
other than kosher manner (e.g., the proxy including mod_mime.h). | |
Module-private header files (the proxy, mod_mime, the regex library, | |
and mod_rewrite) have not been moved to src/include; nor have | |
the OS-abstraction files. [Ken Coar] | |
*) Fix a bug where r->hostname didn't have the :port stripped | |
from it. [Dean Gaudet] | |
*) Tweaked the headers_out table size, and the subprocess_env | |
table size guess in rename_original_environment(). Added | |
MAKE_TABLE_PROFILE which can help discover make_table() | |
calls that use too small an initial guess, see alloc.c. | |
[Dean Gaudet] | |
*) Options and AllowOverride weren't properly merging in the main | |
server setting inside vhosts (only an issue when you have no | |
<Directory> or other section containing an Options that affects | |
a request). Options +foo or -foo in the main_server wouldn't | |
affect the main_server's lookup defaults. [Dean Gaudet] | |

[Ken Coar] PR#1738 | |
*) r->allowed handling cleaned up in the standard modules. | |
[Dean Gaudet] | |

RFC2068. [Dean Gaudet] | |
*) SIGURG doesn't exist everywhere. | |
[Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>] | |
*) mod_unique_id was erroneously generating a second unique id when | |
an internal redirect occured. Such redirects occur, for example, | |
when processing a DirectoryIndex match. [Dean Gaudet] | |
*) API: table_add, table_merge, and table_set include implicit pstrdup() | |
of the key and value. But in many cases this is not required | |
because the key/value is a constant, or the value has been built | |
by pstrcat() or other similar means. New routines table_addn, | |
table_mergen, and table_setn have been added to the API, these | |
routines do not pstrdup() their arguments. The core code and | |
standard modules were changed to take advantage of these routines. | |
The resulting server is up to 20% faster in some situations. | |
Note that it is easy to get code subtly wrong if you pass a key/value | |
which is in a pool other than the pool of the table. The only | |
safe thing to do is to pass key/values which are in the pool of | |
the table, or in one of the ancestors of the pool of the table. | |
i.e. if the table is part of a subrequest, a value from the main | |
request's pool is OK since the subrequest pool is a sub_pool of the | |
main request's pool (and therefore has a lifespan at most as long as | |
the main pool). There is debugging code which can detect improper | |
usage, enabled by defining POOL_DEBUG. See alloc.c for more details. | |
[Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet] | |
*) More mod_mime_magic cleanup: fewer syscalls; should handle "files" | |
which don't exist on disk more gracefully; handles vhosts properly. | |
Update documentation to reflect the code -- if there's no | |
MimeMagicFile directive then the module is not enabled. | |
[Dean Gaudet] | |
*) PORT: Some older *nix dialects cannot automatically start scripts | |
which begin with a #! interpreter line (the shell starts the scripts | |
appropriately on these platforms). Apache now supports starting of | |
"hashbang-scripts" when the NEED_HASHBANG_EMUL define is set. | |
[Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au> | |
taken from tcsh] | |
*) API: "typedef array_header table" removed from alloc.h, folks should | |
have been writing to use table as if it were an opaque type, but even | |
some standard modules got this wrong. By changing the definition | |
to "typedef struct table table" module authors will receive compile | |
time warnings that they're doing the wrong thing. This change | |
facilitates future changes with more sophisticated table | |
structures. Specifically, module authors should be using table_elts() | |
to get access to an array_header * for the table. [Dean Gaudet] | |
*) API: Renamed new_connection() to avoid namespace collision with LDAP | |
library routines. [Ken Coar, Rasmus Lerdorf] | |
*) WIN32: mod_speling is now available on the Win32 platform. | |
[Marc Slemko] | |
*) For clarity the following compile time definition was changed: | |
SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT | |
Also, for example, HAVE_MMAP would mean to use mmap() scoreboards | |
and not be a general notice that the OS has mmap(). Now the | |
HAVE_MMAP/SHMGET #defines strictly are informational that the | |
OS has that method of shared memory; the type to use for | |
the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD | |
and USE_SHMGET_SCOREBOARD). This allows outside modules to | |
determine if shared memory is available and allows Apache | |
to determine the best method to use for the scoreboard. | |

The choice of flock vs. fcntl was made based on timings which showed that | |
even on non-NFS, non-exported filesystems fcntl() was an order of | |

Now the rewriting engine (the heart of mod_rewrite) is organized more | |
straight-forward, first time well documented and reduced to the really | |
essential parts. All redundant cases were stripped off and processing now | |
is the same for both per-server and per-directory context with only a | |
minimum difference (the prefix stripping in per-dir context). As a | |
side-effect some subtle restrictions and two recently discovered problems | |
are gone: Wrong escaping of QUERY_STRING on redirects in per-directory | |
context and restrictions on the substitution URL on redirects. | |
Additionally some minor source cleanups were done. | |

*) TestCompile was not passing $LIBS [Dean Gaudet] | |
*) Makefile.tmpl was not using $CFLAGS in the link phase. | |
[Martin Kraemer] | |
*) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a | |
rudimentary memory debugger which can be used on live servers with | |
low impact -- it sets all allocated and freed memory bytes to 0xa5. | |
Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc() | |
and free() for each object. This is far more expensive and should | |
only be used for testing with tools such as Electric Fence and | |
Purify. See main/alloc.c for more details. [Dean Gaudet] | |
*) Configure uses a sh trap and didn't set its exitcode properly. | |
[Dean Gaudet] PR#1159 | |
*) Yet another vhost revamp. Add the NameVirtualHost directive which | |
explicitly lists the ip:port pairs that are to be used for name-vhosts. | |
From a given ip:port, regardless what the Host: header is, you can | |
only reach the vhosts defined on that ip:port. The precedence of | |
vhosts was reversed to match other precedences in the config -- | |
the earlier vhosts override the later vhosts. All vhost matching was | |
moved into http_vhost.[ch]. [Dean Gaudet] | |
*) ap_inline can be used to force inlining. GNUC __attribute__() can | |
be used for whatever reason is appropriate (i.e. format() warnings | |
for printf style functions). Both are enabled only with | |
gcc >= 2.7.x (so that we have fewer support issues with older | |
versions). [Dean Gaudet] | |
*) Fix support for Proxy Authentication (we were testing the response | |
status too early). [Marc Slemko] | |
*) CoreDumpDirectory directive directs where the core file is | |
written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are | |
received. [Marc Slemko, Dean Gaudet] | |
*) PORT: Support for Atari MINT. | |
[Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>] | |
*) When booting, apache will now detach itself from stdin, stdout, | |
and stderr. stderr will not be detached until after the config | |
files have been read so you will be able to see initial error | |
messages. After that all errors are logged in the error_log. | |
This makes it more convenient to start apache via rsh, ssh, | |
or crontabs. [Dean Gaudet] PR#523 | |
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake. | |
Also removed the auto-generated link to www.apache.org that was the | |
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko] | |
*) send_fb would not detect aborted connections in some situations. | |
[Dean Gaudet] | |
*) mod_include would use uninitialized data when parsing certain | |

*) mod_imap should only handle GET methods. [Jay Bloodworth] | |
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour] | |
*) mod_autoindex improperly counted &escapes; as more than one | |
character in the description. It also improperly truncated | |
descriptions that were exactly the maximum length. | |
[Martin Kraemer] | |
*) RedirectMatch was not properly escaping the result (PR#1155). Also | |
"RedirectMatch /advertiser/(.*) $1" is now permitted. | |
[Dean Gaudet] | |
*) mod_include now uses symbolic names to check for request success | |
and return HTTP errors, and correctly handles all types of | |
redirections (previously it only did temporary redirect correctly). | |
[Ken Coar, Roy Fielding] | |
*) mod_userdir was modifying r->finfo in cases where it wasn't setting | |
r->filename. Since those two are meant to be in sync with each other | |
this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>] | |
*) PORT: Support Unisys SVR4, whose uname returns mostly useless data. | |

jmpbuffer. [Dean Gaudet] PR#1064 | |
*) Work around problem under Linux where a child will start looping | |
reporting a select error over and over. | |
[Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588 | |
*) Fixed error in proxy_util.c when looping through multiple host IP | |
addresses. [Lars Eilebrecht] PR#974 | |
*) If BUFFERED_LOGS is defined then mod_log_config will do atomic | |
buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k) | |
bytes before writing, but it will never split a log entry across a | |
buffer boundary. [Dean Gaudet] | |
*) API: the short_score record has been split into two pieces, one which | |
the parent writes on, and one which the child writes on. As part of | |
this change the get_scoreboard_info() function was removed, and | |
scoreboard_image was exported. This change fixes a race condition | |
in file based scoreboard systems, and speeds up changes involving the | |
scoreboard in earlier 1.3 development. [Dean Gaudet] | |
*) API: New register_other_child() API (see http_main.h) which allows | |
modules to register children with the parent for maintenance. It | |
is disabled by defining NO_OTHER_CHILD. [Dean Gaudet] | |
*) API: New piped_log API (see http_log.h) which implements piped logs, | |
and will use register_other_child to implement reliable piped logs | |
when it is available. The reliable piped logs part can be disabled | |
by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped | |
logs is only available on Unix. [Dean Gaudet] | |
*) API: set_last_modified() broken into set_last_modified(), set_etag(), and | |
meets_conditions(). This allows conditional HTTP selection to be | |
handled separately from the storing of the header fields, and provides | |
the ability for CGIs to set their own ETags for conditional checking. | |
[Ken Coar, Roy Fielding] PR#895 | |
*) Changes to mod_log_config to allow naming of format strings. | |
Format nicknames are defined with "LogFormat fmt nickname", and can | |
be used with "LogFormat nickname" and "CustomLog logtarget nickname". | |
[Ken Coar] | |
*) New module, "mod_speling", which can help find files even when | |
the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut] | |
*) API: New function child_terminate() triggers the child process to | |
exit, while allowing the child finish what it needs to for the | |
current request first. | |
[Doug MacEachern, Alexei Kosut] | |
*) Windows now defaults to using full status reports with mod_status. | |
[Alexei Kosut] PR #1094 | |
*) *Really* disable all mod_rewrite operations if the engine is off. | |
Some things (like RewriteMaps) were checked/performed even if they | |
weren't supposed to be. [Ken Coar] PR #991 | |
*) Implement a new timer scheme which eliminates the need to call alarm() all | |
the time. Instead a counter in the scoreboard for each child is used to | |
show when the child has made forward progress. The parent samples this | |
counter every scoreboard maintenance cycle, and issues SIGALRM if no | |
progress has been made in the timeout period. This reduces the static | |
request best-case syscall count to 22 from 29. This scheme is only | |
used by systems with memory-based scoreboards. [Dean Gaudet] | |
*) The proxy now properly handles CONNECT requests which are sent | |
to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024 | |
*) A script called apachectl has been added to the support | |
directory. This script allows you to do things such as | |
"apachectl start" and "apachectl restart" from the command | |
line. [Marc Slemko] | |
*) Modules and core routines are now put into libraries, which | |
simplifies the link line tremendously (among other advantages). | |
[Paul Sutton] | |
*) Some of the MD5 names defined in Apache have been renamed to have | |
an `ap_' prefix to avoid conflicts with routines supplied by | |
external libraries. [Ken Coar] | |
*) Removal of mod_auth_msql.c from the distribution. There are many | |
other options for databases today. Rather than offer one option, | |
offer none at this time. mod_auth_msql and other SQL database | |
authentication modules can be found at the Apache Module Registry. | |
http://modules.apache.org/ It would be nice to offer a generic | |
mod_auth_sql option in the near future. | |
*) PORT: BeOS support added [Alexei Kosut] | |
*) Configure no longer accepts the -make option, since it creates | |
Makefile on the fly based on Makefile.tmpl and Configuration. | |
*) Apache now gracefully shuts down when it receives a SIGTERM, instead | |
of forcibly killing off all its processes and exiting without | |
cleaning up. [Alexei Kosut] | |
*) API: A new field in the request_rec, r->mtime, has been added to | |
avoid gratuitous parsing of date strings. It is intended to hold | |
the last-modified date of the resource (if applicable). An | |
update_mtime() routine has also been added to advance it if | |
appropriate. [Roy Fielding, Ken Coar] | |
*) SECURITY: If a htaccess file can not be read due to bad permissions, | |
deny access to the directory with a HTTP_FORBIDDEN. The previous | |
behavior was to ignore the htaccess file if it could not be read. | |
This change may make some setups with unreadable htaccess files | |
stop working. [Marc Slemko] PR#817 | |
*) Add aplog_error() providing a mechanism to define levels of | |
verbosity to the server error logging. This addition also provides | |
the ability to log errors using syslogd. Error logging is configurable | |
on a per-server basis using the LogLevel directive. Conversion | |
of log_*() in progress. [Randy Terbush] | |
*) Further enhance aplog_error() to not log filename, line number, and | |
errno information when it isn't applicable. [Ken Coar, Dean Gaudet] | |
*) WIN32: Canonicalise filenames under Win32. Short filenames are | |
converted to long ones. Backslashes are converted to forward | |
slashes. Case is converted to lower. Parts of URLs that do not | |
correspond to files are left completely alone. [Ben Laurie] | |
*) PORT: 2 new OSs added to the list of ports: | |
Encore's UMAX V: Arieh Markel <amarkel encore.com> | |
Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk> | |
*) Add the server version (SERVER_VERSION macro) to the "server | |
configured and running" entry in the error_log. Also build an | |
object file at link-time that contains the current time | |
(SERVER_BUILT global const char[]), and include that in the | |
message. [Ken Coar] | |
*) Set r->headers_out when sending responses from the proxy. | |
This fixes things such as the logging of headers sent from | |
the proxy. [Marc Slemko] PR#659 | |
*) support/httpd_monitor is no longer distributed because the | |
scoreboard should not be file based if at all possible. Use | |
mod_status to see current server snapshot. | |
*) (set_file_slot): New function, allowing auth directives to be | |
independent of the server root, so the server documents can be | |
moved to a different directory or machine more easily. | |
[David J. MacKenzie] | |
*) If no TransferLog is given explicitly, decline | |
to log. This supports coexistence with other logging modules, | |
such as the custom one that UUNET uses. [David J. MacKenzie] | |
*) Check for titles in server-parsed HTML files. | |
Ignore leading newlines and returns in titles. The old behavior | |
of replacing a newline after <title> with a space causes the | |
title to be misaligned in the listing. [David J. MacKenzie] | |
*) Change mod_cern_meta to be configurable on a per-directory basis. | |
[David J. MacKenzie] | |
*) Add 'Include' directive to allow inclusion of configuration | |
files within configuration files. [Randy Terbush] | |
*) Proxy errors on connect() are logged to the error_log (nothing | |
new); now they include the IP address and port that failed | |
(*that's* new). [Ken Coar, Marc Slemko] PR#352 | |
*) Various architectures now define USE_MMAP_FILES which causes | |
the server to use mmap() for static files. There are two | |
compile-time tunables MMAP_THRESHOLD (minimum number of bytes | |
required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum | |
number of bytes written in one cycle from a single mmap()d object, | |
default 32768). [Dean Gaudet] | |
*) API: Added post_read_request API phase which is run right after reading | |
the request from a client, or right after an internal redirect. It is | |
useful for modules setting environment variables that depend only on | |
the headers/contents of the request. It does not run during subrequests | |
because subrequests inherit pretty much everything from the main | |
request. [Dean Gaudet] | |
*) Added mod_unique_id which is used to generate a unique identifier for | |
each hit, available in the environment variable UNIQUE_ID. | |
[Dean Gaudet] | |
*) init_modules is now called after the error logs have been opened. This | |
allows modules to emit information messages into the error logs. | |
[Dean Gaudet] | |
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging | |
information for case where proxy module is not available. [Marc Slemko] | |
*) PORT: Apache has need for mutexes to serialize its children around | |
accept. In prior versions either fcntl file locking or flock file | |
locking were used. The method is chosen by the definition of | |
USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(), | |
and FLOCK for flock(). New options have been added: | |
- SYSVSEM to use System V style semaphores | |
- PTHREAD to use POSIX threads (appears to work on Solaris only) | |
- USLOCK to use IRIX uslock | |
Based on timing various techniques, the following changes were made | |
to the defaults: | |
- Linux 2.x uses flock instead of fcntl | |
- Solaris 2.x uses pthreads | |
- IRIX uses SysV semaphores -- however multiprocessor IRIX boxes | |
work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT | |
[Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>, | |
Martijn Koster <m.koster pobox.com>] | |
*) PORT: The semantics of accept/select make it very desirable to use | |
mutexes to serialize accept when multiple Listens are in use. But | |
in the case where only a single socket is open it is sometimes | |
redundant to serialize accept(). Not all unixes do a good job with | |
potentially dozens of children blocked on accept() on the same | |
socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and | |
the server will avoid serialization when listening on only one socket, | |
and use serialization when listening on multiple sockets. | |
[Dean Gaudet] PR#467 | |
*) Configure changes: TestLib replaced by TestCompile, which has | |
some additional capability (such as doing a sanity check of | |
the compiler and flags selected); the version of Solaris is now | |
available via the #define value of SOLARIS2; IRIX n32bit libs | |
now supported and selectable by new Configuration Rule: IRIXN32; | |
We no longer default to -O2 optimization. [Jim Jagielski] | |
*) Updated Configure: Configuration now uses AddModule to specify | |
module source or binary file location, relative to src directory. | |
Modules can be dropped into modules/extra, or in their own | |
directory, and modules can come with a Makefile or Configure can | |
create one. Modules can add compiler or library information to | |
generated Makefiles. [Paul Sutton] | |
*) Source core re-organisation: distributed modules are now in | |
modules/standard. All other source code is in main. OS-specific | |
code is in os/{unix,emx,win32} directories. [Paul Sutton] | |
*) mod_browser has been removed, since it's replaced by mod_setenvif. | |
[Ken Coar] | |
*) Fix another long-standing bug in sub_req_lookup_file where it would | |
happily skip past access checks on subdirectories looked up with | |
relative paths. (It's used by mod_dir, mod_negotiation, | |
and mod_include.) [Dean Gaudet] | |
*) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where | |
N is the number of <Directory> sections, and M is the number of | |
components in the filename of an object. | |
To achieve this optimization the following config changes were made: | |
- Wildcards (* and ?, not the regex forms) in <Directory>s, | |
<Files>s, and <Location>s now treat a slash as a special | |
character. For example "/home/*/public_html" previously would | |
match "/home/a/andrew/public_html", now it only matches things | |
like "/home/bob/public_html". This mimics /bin/sh behaviour. | |
- It's possible now to use [] wildcarding in <Directory>, <Files> | |
or <Location>. | |
- Regex <Directory>s are applied after all non-regex <Directory>s. | |
[Dean Gaudet] | |
*) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files | |
and corrupted paths. [Dean Gaudet] | |
*) Enhanced and cleaned up the URL rewriting engine of mod_rewrite: | |
First the grouped parts of RewriteRule pattern matches (parenthesis!) can | |
be accessed now via backreferences $1..$9 in RewriteConds test-against | |
strings in addition to RewriteRules subst string. Second the grouped | |
parts of RewriteCond pattern matches (parenthesis!) can be accessed now | |
via backreferences %1..%9 both in following RewriteCond test-against | |
strings and RewriteRules subst string. This provides maximum flexibility | |
through the use of backreferences. | |
Additionally the rewriting engine was cleaned up by putting common | |
code to the new expand_backrefs_inbuffer() function. | |
[Ralf S. Engelschall] | |
*) When merging the main server's <Directory> and <Location> sections into | |
a vhost, put the main server's first and the vhost's second. Otherwise | |
the vhost can't override the main server. [Dean Gaudet] PR#717 | |
*) The <Directory> code would merge and re-merge the same section after | |
a match was found, possibly causing problems with some modules. | |
[Dean Gaudet] | |
*) ip-based vhosts are stored and queried using a hashing function, which | |
has been shown to improve performance on servers with many ip-vhosts. | |
Some other changes had to be made to accommodate this: | |
- the * address for vhosts now behaves like _default_ | |
- the matching process now is: | |
- match an ip-vhost directly via hash (possibly matches main | |
server) | |
- if that fails, just pretend it matched the main server | |
- if so far only the main server has been matched, perform | |
name-based lookups (ServerName, ServerAlias, ServerPath) | |
*only on name-based vhosts* | |
- if they fail, look for _default_ vhosts | |
[Dean Gaudet, Dave Hankins <dhankins sugarat.net>] | |
*) dbmmanage overhaul: | |
- merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new | |
- tie() to AnyDBM_File which will use one of DB_File, NDBM_File or | |
GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order) | |
- provide better seed for rand | |
- prompt for password as per getpass(3) (turn off echo, read from | |
/dev/tty, etc.) | |
- use "newstyle" crypt based on $Config{osname} ($^O) | |
- will not add a user if already in database, use new `update' command | |
instead | |
- added `check' command to check a users' password | |
- added `import' command to convert existing password text-files or | |
dbm files exported with `view' | |
- more descriptive usage, general cleanup, 'use strict' clean, etc. | |
[Doug MacEachern] | |
*) Added psocket() which is a pool form of socket(), various places within | |
the proxy weren't properly blocking alarms while registering the cleanup | |
for its sockets. bclose() now uses pclose() and pclosesocket(). There | |
was a bug where the client socket was being close()d twice due a still | |
registered cleanup. [Dean Gaudet] | |
*) A few cleanups were made to reduce time(), getpid(), and signal() calls. | |
[Dean Gaudet] | |
*) PORT: AIX >= 4.2 requires -lm due to libc changes. | |
[Jason Venner <jason idiom.com>] PR#667 | |
*) Enable ``=""'' for RewriteCond directives to match against | |
the empty string. This is the preferred way instead of ``^$''. | |
[Ralf S. Engelschall] | |
*) Fixed an infinite loop in mod_imap for references above the server root | |
[Dean Gaudet] PR#748 | |
*) mod_proxy now has a ReceiveBufferSize directive, similar to | |
SendBufferSize, so that the TCP window can be set appropriately | |
for LFNs. [Phillip A. Prindeville] | |
*) mod_browser has been replaced by the more general mod_setenvif | |
(courtesy of Paul Sutton). BrowserMatch* directives are still | |
available, but are now joined by SetEnvIf*, UnSetEnvIf*, and | |
UnSetEnvIfZero directives. [Ken Coar] | |
*) "HostnameLookups double" forces double-reverse DNS to succeed in | |
order for remote_host to be set (for logging, or for the env var | |
REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated. | |
[Dean Gaudet] | |
*) mod_access overhaul: | |
- Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0) | |
and cidr syntax (i.e. 10.1.0.0/16). PR#762 | |
- Critical path was sped up by pre-computing a few things at config time. | |
- The undocumented syntax "allow user-agents" was removed, | |
the replacement is "allow from env=foobar" combined with mod_browser. | |
- When used with hostnames it now forces a double-reverse lookup | |
no matter what the directory settings are. This double-reverse | |
doesn't affect any of the other routines that use the remote | |
hostname. In particular it's still passed to CGIs and the log | |
without the double-reverse check. Related PR#860. | |
[Dean Gaudet] | |
*) When a large bwrite() occurs (larger than the internal buffer size), | |
while there is already something in the buffer, apache will combine | |
the large write and the buffer into a single writev(). (This is | |
in anticipation of using mmap() for reading files.) | |
[Dean Gaudet] | |
*) In obscure cases where a partial socket write occurred while chunking, | |
Apache would omit the chunk header/footer on the next block. Cleaned | |
up other bugs/inconsistencies in error conditions in buff.c. Fixed | |
a bug where a long pause in DNS lookups could cause the last packet | |
of a response to be unduly delayed. [Roy Fielding, Dean Gaudet] | |
*) API: Added child_exit function to module structure. This is called | |
once per "heavy-weight process" just before a server child exit()'s | |
e.g. when max_requests_per_child is reached, etc. | |
[Doug MacEachern, Dean Gaudet] | |
*) mod_include cleanup showed that handle_else was being used to handle | |
endif. It didn't cause problems, but it was cleaned up too. | |
[Howard Fear] | |
*) mod_cern_meta would attempt to find meta files for the directory itself | |
in some cases, but not in others. It now avoids it in all cases. | |
[Dean Gaudet] | |
*) mod_mime_magic would core dump if there was a decompression error. | |
[Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904 | |
*) PORT: some variants of DGUX require -lsocket -lnsl | |
[Alexander L Jones <alex systems-options.co.uk>] PR#732 | |
*) mod_autoindex now allows sorting of FancyIndexed directory listings | |
by the various fields (name, size, et cetera), either in ascending | |
or descending order. Just click on the column header. [Ken Coar] | |
*) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit | |
CPUs like the Alpha. Apache still stores ints in pointers, but that's | |
the relatively safe direction. [Dean Gaudet] PR#344 | |
*) PORT: QNX mmap() support for faster/more reliable scoreboard handling. | |
[Igor N Kovalenko <infoh mail.wplus.net>] PR#683 | |
*) child_main avoids an unneeded call to select() when there is only one | |
listening socket. [Dean Gaudet] | |
*) In the event that the server is starved for idle servers it will | |
spawn 1, then 2, then 4, ..., then 32 servers each second, | |
doubling each second. It'll also give a warning in the errorlog | |
since the most common reason for this is a poor StartServers | |
setting. The define MAX_SPAWN_RATE can be used to raise/lower | |
the maximum. [Dean Gaudet] | |
*) Apache now provides an effectively unbuffered connection for | |
CGI scripts. This means that data will be sent to the client | |
as soon as the CGI pauses or stops output; previously, Apache would | |
buffer the output up to a fixed buffer size before sending, which | |
could result in the user viewing an empty page until the CGI finished | |
or output a complete buffer. It is no longer necessary to use an | |
"nph-" CGI to get unbuffered output. Given that most CGIs are written | |
in a language that by default does buffering (e.g. perl) this | |
shouldn't have a detrimental effect on performance. | |
"nph-" CGIs, which formerly provided a direct socket to the client | |
without any server post-processing, were not fully compatible with | |
HTTP/1.1 or SSL support. As such they would have had to implement | |
the transport details, such as encryption or chunking, in order | |
to work properly in certain situations. Now, the only difference | |
between nph and non-nph scripts is "non-parsed headers". | |
[Dean Gaudet, Sameer Parekh, Roy Fielding] | |
*) If a BUFF is switched from buffered to unbuffered reading the first | |
bread() will return whatever remained in the buffer prior to the | |
switch. [Dean Gaudet] | |
Changes with Apache 1.3a1 | |
*) Added another Configure helper script: TestLib. It determines | |
if a specified library exists. [Jim Jagielski] | |
*) PORT: Allow for use of n32bit libraries under IRIX 6.x | |
[derived from patch from Jeff Hayes <jhayes aw.sgi.com>] | |
PR#721 | |
*) PORT: Some architectures use size_t for various lengths in network | |
functions such as accept(), and getsockname(). The definition | |
NET_SIZE_T is used to control this. [Dean Gaudet] | |
*) PORT: Linux: Attempt to detect glibc based systems and include crypt.h | |
and -lcrypt. Test for various db libraries (dbm, ndbm, db) when | |
mod_auth_dbm or mod_auth_db are included. [Dean Gaudet] | |
*) PORT: QNX doesn't have initgroups() which support/suexec.c uses. | |
[Igor N Kovalenko <infoh mail.wplus.net>] | |
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to | |
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added | |
"downgrade-1.0" which causes Apache to pretend it received a 1.0. | |
[Dean Gaudet] related PR#875 | |
*) API: Correct child_init() slot declaration from int to void, to | |
match the init() declaration. Update mod_example to use the new | |
hook. [Ken Coar] | |
*) added transport handle slot (t_handle) to the BUFF structure | |
[Doug MacEachern] | |
*) get_client_block() returns wrong length if policy is | |
REQUEST_CHUNKED_DECHUNK. | |
[Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815 | |
*) Support the image map format of FrontPage. For example: | |
rect /url.hrm 10 20 30 40 | |
["Chris O'Byrne" <obyrne iol.ie>] PR#807 | |
*) PORT: -lresolv and -lsocks were in the wrong order for Solaris. | |
["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846 | |
*) AddModuleInfo directive for mod_info which allows you to annotate | |
the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>] | |
*) Added NoProxy directive to avoid using ProxyRemote for selected | |
addresses. Added ProxyDomain directive to cause unqualified | |
names to be qualified by redirection. | |
[Martin Kraemer <Martin.Kraemer mch.sni.de>] | |
*) Support Proxy Authentication, and don't pass the Proxy-Authorize | |
header to the remote host in the proxy. [Sameer Parekh and | |
Wallace] | |
*) Upgraded mod_rewrite from 3.0.6+ to latest officially available version | |
3.0.9. This upgrade includes: fixed deadlooping on rewriting to same | |
URLs, fixed rewritelog(), fixed forced response code handling on | |
redirects from within .htaccess files, disabled pipe locking under | |
braindead SunOS 4.1.x, allow env variables to be set even on rules with | |
no substitution, bugfixed situations where HostnameLookups is off, made | |
mod_rewrite more thread-safe for NT port and fixed problem when creating | |
an empty query string via "xxx?". | |
This update also removes the copyright of Ralf S. Engelschall, | |
i.e. now mod_rewrite no longer has a shared copyright. Instead is is | |
exclusively copyrighted by the Apache Group now. This happened because | |
the author now has gifted mod_rewrite exclusively to the Apache Group and | |
no longer maintains an external version. | |
[Ralf S. Engelschall] | |
*) API: Added child_init function to module structure. This is called | |
once per "heavy-weight process" before any requests are handled. | |
See http_config.h for more details. [Dean Gaudet] | |
*) Anonymous_LogEmail was logging on each subrequest. | |
[Dean Gaudet] PR#421, 868 | |
*) API: Added is_initial_req() which tests if the request being | |
processed is the initial request, or a subrequest. | |
[Doug MacEachern] | |
*) Extended SSI (mod_include) now handles additional relops for | |
string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41 | |
*) Configure fixed to correctly propagate user-selected options and | |
settings (such as CC and OPTIM) to Makefiles other than | |
src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834 | |
*) IndexOptions SuppressHTMLPreamble now causes the actual HTML of | |
directory indices to start with the contents of the HeaderName file | |
if there is one. If there isn't one, the behaviour is unchanged. | |
[Ken Coar, Roy Fielding, Andrey A. Chernov] | |
*) WIN32: Modules can now be dynamically loaded DLLs using the | |
LoadModule/LoadFile directives. Note that module DLLs must be | |
compiled with the multithreaded DLL version of the runtime library. | |
[Alexei Kosut and Ben Laurie] | |
*) Automatic indexing removed from mod_dir and placed into mod_autoindex. | |
This allows the admin to completely remove automatic indexing | |
from the server, while still supporting the basic functions of | |
trailing-slash redirects and DirectoryIndex files. Note that if | |
you're carrying over an old Configuration file and you use directory | |
indexing then you'll want to add: | |
Module autoindex_module mod_autoindex.o | |
before mod_dir in your Configuration. [Dean Gaudet] | |
*) popendir/pclosedir created to properly protect directory scanning. | |
[Dean Gaudet] PR#525 | |
*) AliasMatch, ScriptAliasMatch and RedirectMatch directives added, | |
giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch> | |
and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc... | |
[Alexei Kosut] | |
*) The AccessFileName directive can now take more than one filename. | |
["Lou D. Langholtz" <ldl usi.utah.edu>] | |
*) The new mod_mime_magic can be used to "magically" determine the type | |
of a file if the extension is unknown. Based on the unix file(1) | |
command. [Ian Kluft <ikluft cisco.com>] | |
*) We now determine and display the time spent processing a | |
request if desired. [Jim Jagielski] | |
*) mod_status: PID field of "dead" child slots no longer displays | |
main httpd process's PID. [Jim Jagielski] | |
*) Makefile.nt added - to build all the bits from the command line: | |
nmake -f Makefile.nt | |
Doesn't yet work properly. [Ben Laurie] | |
*) Default text of 404 error is now "Not Found" rather than the | |
potentially misleading "File Not Found". [Ken Coar] | |
*) CONFIG: "HostnameLookups" now defaults to off because it is far better | |
for the net if we require people that actually need this data to | |
enable it. [Linus Torvalds] | |
*) directory_walk() is an expensive function, keep a little more state to | |
avoid needless string counting. Add two new functions make_dirstr_parent | |
and make_dirstr_prefix which replace all existing uses of make_dirstr. | |
The new functions are a little less general than make_dirstr, but | |
work more efficiently (less memory, less string counting). | |
[Dean Gaudet] | |
*) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed | |
to LDFLAGS) to avoid complications with lex rules in make files. | |
[Dean Gaudet] PR#372 | |
*) run_method optimized to avoid needless scanning over NULLs in the | |
module list. [Dean Gaudet] | |
*) Revamp of (unix) scoreboard management code such that it avoids | |
unnecessary traversals of the scoreboard on each hit. This is | |
particularly important for high volume sites with a large | |
HARD_SERVER_LIMIT. Some of the previous operations were O(n^2), | |
and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in | |
httpd.h. [Dean Gaudet] | |
*) In configurations using multiple Listen statements it was possible for | |
busy sockets to starve other sockets of service. [Dean Gaudet] | |
*) Added hook so standalone_main can be replaced at compile time | |
(define STANDALONE_MAIN) | |
[Doug MacEachern] | |
*) Lowest-level read/write functions in buff.c will be replaced with | |
the SFIO library calls sfread/sfwrite if B_SFIO is defined at | |
compile time. The default sfio discipline will behave as apache | |
would without sfio compiled in. | |
[Doug MacEachern] | |
*) Enhance UserDir directive (mod_userdir) to accept a list of | |
usernames for the 'disable' keyword, and add 'enable user...' to | |
selectively *en*able userdirs if they're globally disabled. | |
[Ken Coar] | |
*) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache | |
will work with Netscape dbm files. (dbmmanage will probably not | |
work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444 | |
*) Add a ListenBacklog directive to control the backlog parameter | |
passed to listen(). Also change the default to 511 from 512. | |
[Marc Slemko] | |
*) API: A new handler response DONE which informs apache that the | |
request has been handled and it can finish off quickly, similar to | |
how it handles errors. [Rob Hartill] | |
*) Turn off chunked encoding after sending terminating chunk/footer | |
so that we can't do it twice by accident. [Roy Fielding] | |
*) mod_expire also issues Cache-Control: max-age headers. | |
[Rob Hartill] | |
*) API: Added kill_only_once option for free_proc_chain so that it won't | |
aggressively try to kill off specific children. For fastcgi. | |
[Stanley Gambarin <gambarin OpenMarket.com>] | |
*) mod_auth deals with extra ':' delimited fields. [Marc Slemko] | |
*) Added IconHeight and IconWidth to mod_dir's IndexOptions directive. | |
When used together, these cause mod_dir to emit HEIGHT and WIDTH | |
attributes in the FancyIndexing IMG tags. [Ken Coar] | |
*) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski] | |
*) PORT: Added Windows NT support | |
[Ben Laurie and Ambarish Malpani <ambarish valicert.com>] | |
Changes with Apache 1.2.6 | |
*) mod_include when using XBitHack Full would send ETags in addition to | |
sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour. | |
[Dean Gaudet] PR#1133 | |
*) SECURITY: When a client connects to a particular port/addr, and | |
gives a Host: header ensure that the virtual host requested can | |
actually be reached via that port/addr. [Ed Korthof <ed organic.com>] | |
*) Support virtual hosts with wildcard port and/or multiple ports | |
properly. [Ed Korthof <ed organic.com>] | |
*) Fixed some case-sensitivity issues according to RFC2068. | |
[Dean Gaudet] | |
*) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c, | |
and mod_include.c. [Dean Gaudet] | |
*) Variable 'cwd' was being used pointlessly before being set. | |
[Ken Coar] PR#1738 | |
*) SIGURG doesn't exist on all platforms. | |
[Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>] | |
*) When an error occurs during a POST, or other operation with a | |
request body, the body has to be read from the net before allowing | |
a keepalive session to continue. [Roy Fielding] PR#1399 | |
*) When an error occurs in fcntl() locking suggest the user look up | |
the docs for LockFile. [Dean Gaudet] | |
*) table_set() and table_unset() did not deal correctly with | |
multiple occurrences of the same key. [Stephen Scheck | |
<sscheck infonex.net>, Ben Laurie] PR#1604 | |
*) send_fd_length() did not calculate total_bytes_sent properly in error | |
cases. [Ben Reser <breser regnow.com>] PR#1366 | |
*) r->connection->user was allocated in the wrong pool causing corruption | |
in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500 | |
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake. | |
Also removed the auto-generated link to www.apache.org that was the | |
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko] | |
*) Multiple "close" tokens may have been set in the "Connection" | |
header, not an error, but a waste. | |
[<Ronald.Tschalaer psi.ch>] PR#1683 | |
*) "basic" and "digest" auth tokens should be tested case-insensitive. | |
[<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666 | |
*) It appears the "257th byte" bug (see | |
htdocs/manual/misc/known_client_problems.html#257th-byte) can happen | |
at the 256th byte as well. Fixed. [Dean Gaudet] | |
*) mod_rewrite would not handle %3f properly in some situations. | |
[Ralf Engelschall] | |
*) Apache could generate improperly chunked HTTP/1.1 responses when | |
the bputc() or rputc() functions were used by modules (such as | |
mod_include). [Dean Gaudet] | |
*) #ifdef wrap a few #defines in httpd.h to make life easier on | |
some ports. [Ralf Engelschall] | |
*) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby] | |
*) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer] | |
*) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer] | |
Changes with Apache 1.2.5 | |
*) SECURITY: Fix a possible buffer overflow in logresolve. This is | |
only an issue on systems without a MAXDNAME define or where | |
the resolver returns domain names longer than MAXDNAME. [Marc Slemko] | |
*) Fix an improper length in an ap_snprintf call in proxy_date_canon(). | |
[Marc Slemko] | |
*) Fix core dump in the ftp proxy when reading incorrectly formatted | |
directory listings. [Marc Slemko] | |
*) SECURITY: Fix possible minor buffer overflow in the proxy cache. | |
[Marc Slemko] | |
*) SECURITY: Eliminate possible buffer overflow in cfg_getline, which | |
is used to read various types of files such as htaccess and | |
htpasswd files. [Marc Slemko] | |
*) SECURITY: Ensure that the buffer returned by ht_time is always | |
properly null terminated. [Marc Slemko] | |
*) SECURITY: General mod_include cleanup, including fixing several | |
possible buffer overflows and a possible infinite loop. This cleanup | |
was done against 1.3 code and then backported to 1.2, the result | |
is a large difference (due to indentation cleanup in 1.3 code). | |
Users interested in seeing a smaller set of relevant differences | |
should consider comparing against src/modules/standard/mod_include.c | |
from the 1.3b3 release. Non-indentation changes to mod_include | |
between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko] | |
*) SECURITY: Numerous changes to mod_imap in a general cleanup | |
including fixing a possible buffer overflow. This cleanup also | |
was done with 1.3 code as a basis, see the the previous note | |
about mod_include. [Dean Gaudet] | |
*) SECURITY: If a htaccess file can not be read due to bad | |
permissions, deny access to the directory with a HTTP_FORBIDDEN. | |
The previous behavior was to ignore the htaccess file if it could not | |
be read. This change may make some setups with unreadable | |
htaccess files stop working. PR#817 [Marc Slemko] | |
*) SECURITY: no2slash() was O(n^2) in the length of the input. | |
Make it O(n). This inefficiency could be used to mount a denial | |
of service attack against the Apache server. Thanks to | |
Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting | |
this. [Dean Gaudet] | |

[Jay Bloodworth <jay pathways.sde.state.sc.us>] | |
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour] | |
*) mod_userdir was modifying r->finfo in cases where it wasn't setting | |
r->filename. Since those two are meant to be in sync with each other | |
this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>] | |
*) mod_include did not properly handle all possible redirects from sub- | |
requests. [Ken Coar] | |
*) Inetd mode (which is buggy) uses timeouts without having setup the | |
jmpbuffer. [Dean Gaudet] PR#1064 | |
*) Work around problem under Linux where a child will start looping | |
reporting a select error over and over. | |
[Rick Franchuk <rickf transpect.net>] PR#1107 | |
Changes with Apache 1.2.4 | |
*) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy | |
always making requests with the full-URI instead of just the URI path. | |
[Marc Slemko, Roy Fielding] | |
*) Add -lm for AIX versions >= 4.2 to allow Apache to link properly | |
on this platform. [Marc Slemko] | |
Changes with Apache 1.2.3 | |
*) The request to a remote proxy was mangled if it was generated as the | |
result of a ProxyPass directive. URL schemes other than http:// were not | |
supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713, | |
PR#812 [Lars Eilebrecht] | |
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging | |
information for case where proxy module is not available. [Marc Slemko] | |
*) Force proxy to always respond as HTTP/1.0, which it was failing to | |
do for errors and cached responses. [Roy Fielding] | |
*) PORT: Improved support for ConvexOS 11. [Jeff Venters] | |
Changes with Apache 1.2.2 [not released] | |
*) Fixed another long-standing bug in sub_req_lookup_file where it would | |
happily skip past access checks on subdirectories looked up with relative | |
paths. (It's used by mod_dir, mod_negotiation, and mod_include.) | |
[Dean Gaudet] | |
*) Add lockfile name to error message printed out when | |
USE_FLOCK_SERIALIZED_ACCEPT is defined. | |
[Marc Slemko] | |
*) Enhanced the chunking and error handling inside the buffer functions. | |
[Dean Gaudet, Roy Fielding] | |
*) When merging the main server's <Directory> and <Location> sections into | |
a vhost, put the main server's first and the vhost's second. Otherwise | |
the vhost can't override the main server. [Dean Gaudet] PR#717 | |
*) The <Directory> code would merge and re-merge the same section after | |
a match was found, possibly causing problems with some modules. | |
[Dean Gaudet] | |
*) Fixed an infinite loop in mod_imap for references above the server root. | |
[Dean Gaudet] PR#748 | |
*) mod_include cleanup showed that handle_else was being used to handle | |
endif. It didn't cause problems, but it was cleaned up too. | |
[Howard Fear] | |
*) Last official synchronization of mod_rewrite with author version (because | |
mod_rewrite is now directly developed by the author at the Apache Group): | |
o added diff between mod_rewrite 3.0.6+ and 3.0.9 | |
minus WIN32/NT stuff, but plus copyright removement. | |

*) Anonymous_LogEmail was logging on each subrequest. | |
[Dean Gaudet] PR#421, PR#868 | |
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to | |
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added | |
"downgrade-1.0" which causes Apache to pretend it received a 1.0. | |
Additionally mod_browser now triggers during translate_name to workaround | |
a deficiency in the header_parse phase. | |
[Dean Gaudet] PR#875 | |
*) get_client_block() returns wrong length if policy is | |
REQUEST_CHUNKED_DECHUNK. | |
[Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815 | |
*) Properly treat <files> container like other containers in mod_info. | |
[Marc Slemko] PR#848 | |
*) The proxy didn't treat the "Host:" keyword of the host header as case- | |
insensitive. The proxy would corrupt the first line of a response from | |
an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814 | |
*) mod_include would log some bogus values occasionally. | |
[Skip Montanaro <skip calendar.com>, Marc Slemko] PR#797 | |
*) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP | |
under Solaris 2.x (up through 2.5.1). It has been fixed. | |
[Dean Gaudet] PR#832 | |
*) API: In HTTP/1.1, whether or not a request message contains a body | |
is independent of the request method and based solely on the presence | |
of a Content-Length or Transfer-Encoding. Therefore, our default | |
handlers need to be prepared to read a body even if they don't know | |
what to do with it; otherwise, the body would be mistaken for the | |
next request on a persistent connection. discard_request_body() | |
has been added to take care of that. [Roy Fielding] PR#378 | |
*) API: Symbol APACHE_RELEASE provides a numeric form of the Apache | |
release version number, such that it always increases along the | |
same lines as our source code branching. [Roy Fielding] | |
*) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94 | |
Changes with Apache 1.2.1 | |
*) SECURITY: Don't serve file system objects unless they are plain files, | |
symlinks, or directories. This prevents local users from using pipes | |
or named sockets to invoke programs for an extremely crude form of | |
CGI. [Dean Gaudet] | |
*) SECURITY: HeaderName and ReadmeName were settable in .htaccess and | |
could contain "../" allowing a local user to "publish" any file on | |
the system. No slashes are allowed now. [Dean Gaudet] | |
*) SECURITY: It was possible to violate the symlink Options using mod_dir | |
(headers, readmes, titles), mod_negotiation (type maps), or | |
mod_cern_meta (meta files). [Dean Gaudet] | |
*) SECURITY: Apache will refuse to run as "User root" unless | |
BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet] | |
*) CONFIG: If a symlink pointed to a directory then it would be disallowed | |
if it contained a .htaccess disallowing symlinks. This is contrary | |
to the rule that symlink permissions are tested with the symlink | |
options of the parent directory. [Dean Gaudet] PR#353 | |
*) CONFIG: The LockFile directive can be used to place the serializing | |
lockfile in any location. It previously defaulted to /usr/tmp/htlock. | |
[Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet, | |
Marc Slemko] | |
*) Request processing now retains state of whether or not the request | |
body has been read, so that internal redirects and subrequests will | |
not try to read it twice (and block). [Roy Fielding] | |
*) Add a placeholder in modules/Makefile to avoid errors with certain | |
makes. [Marc Slemko] | |
*) QUERY_STRING was unescaped in mod_include, it shouldn't be. | |
[Dean Gaudet] PR#644 | |
*) mod_include was not properly changing the current directory. | |
[Marc Slemko] PR#742 | |
*) Attempt to work around problems with third party libraries that do not | |
handle high numbered descriptors (examples include bind, and | |
solaris libc). On all systems apache attempts to keep all permanent | |
descriptors above 15 (called the low slack line). Solaris users | |
can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS | |
which keeps all non-FILE * descriptors above 255. On all systems | |
this should make supporting large numbers of vhosts with many open | |
log files more feasible. If this causes trouble please report it, | |
you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS. | |
[Dean Gaudet] various PRs | |
*) Related to the last entry, network sockets are now opened before | |
log files are opened. The only known case where this can cause | |
problems is under Solaris with many virtualhosts and many Listen | |
directives. But using -DHIGH_SLACK_LINE=256 described above will | |
work around this problem. [Dean Gaudet] | |
*) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and | |
SunOS 4. | |
*) Improved unix error response logging. [Marc Slemko] | |
*) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag | |
QSA=query_string_append. Also fixed a nasty bug in per-dir context: | |
when a URL http://... was used in conjunction with a special | |
redirect flag, e.g. R=permanent, the permanent status was lost. | |
[Ronald Tschalaer <Ronald.Tschalaer psi.ch>, Ralf S. Engelschall] | |
*) If an object has multiple variants that are otherwise equal Apache | |
would prefer the last listed variant rather than the first. | |
[Paul Sutton] PR#94 | |
*) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752 | |
*) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding] | |
PR#566 | |
*) pregsub had an off-by-1 in its error checking code. [Alexei Kosut] | |
*) PORT: fix rlim_t problems with AIX 4.2. [Marc Slemko] PR#333 | |

Changes with Apache 1.2 | |
Changes with Apache 1.2b11 | |
*) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko] | |
*) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl. | |
[Doug MacEachern, Rob Hartill] | |
*) Proxy needs to use hard_timeout instead of soft_timeout when it is | |
reading from one buffer and writing to another, at least until it has | |
a custom timeout handler. [Roy Fielding and Petr Lampa] | |
*) Fixed problem on IRIX with servers hanging in IdentityCheck, | |
apparently due to a mismatch between sigaction and setjmp. | |
[Roy Fielding] PR#502 | |
*) Log correct status code if we timeout before receiving a request (408) | |
or if we received a request-line that was too long to process (414). | |
[Ed Korthof and Roy Fielding] PR#601 | |
*) Virtual hosts with the same ServerName, but on different ports, were | |
not being selected properly. [Ed Korthof] | |
*) Added code to return the requested IP address from proxy_host2addr() | |
if gethostbyaddr() fails due to reverse DNS lookup problems. Original | |
change submitted by Jozsef Hollosi <hollosi sbcm.com>. | |
[Chuck Murcko] PR#614 | |
*) If multiple requests on a single connection are used to retrieve | |
data from different virtual hosts, the virtual host list would be | |
scanned starting with the most recently used VH instead of the first, | |
causing most virtual hosts to be ignored. | |
[Paul Sutton and Martin Mares] PR#610 | |
*) The OS/2 handling of process group was broken by a porting patch for | |
MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley] | |
*) Inherit virtual server port from main server if none (or "*") is | |
given for VirtualHost. [Dean Gaudet] PR#576 | |
*) If the lookup for a DirectoryIndex name with content negotiation | |
has found matching variants, but none are acceptable, return the | |
negotiation result if there are no more DirectoryIndex names to lookup. | |
[Petr Lampa and Roy Fielding] | |
*) If a soft_timeout occurs after keepalive is set, then the main child | |
loop would try to read another request even though the connection | |
has been aborted. [Roy Fielding] | |
*) Configure changes: Allow for whitespace at the start of a | |
Module declaration. Also, be more understanding about the | |
CC=/OPTIM= format in Configuration. Finally, fix compiler | |
flags if using HP-UX's cc compiler. [Jim Jagielski] | |
*) Subrequests and internal redirects now inherit the_request from the | |
original request-line. [Roy Fielding] | |
*) Test for error conditions before creating output header fields, since | |
we don't want the error message to include those fields. Likewise, | |
reset the content_language(s) and content_encoding of the response | |
before generating or redirecting to an error message, since the new | |
message will have its own Content-* definitions. [Dean Gaudet] | |
*) Restored the semantics of headers_out (headers sent only with 200..299 | |
and 304 responses) and err_headers_out (headers sent with all responses). | |
Avoid the overhead of copying tables if err_headers_out is empty | |
(the usual case). [Roy Fielding] | |
*) Fixed a couple places where a check for the default Content-Type was | |
not properly checking both the value configured by the DefaultType | |
directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value | |
of DEFAULT_TYPE to match the documented default (text/plain). | |
[Dean Gaudet] PR#506 | |
*) Escape the HTML-sensitive characters in the Request-URI that is | |
output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501 | |
*) Properly initialize the flock structures used by the mutex locking | |
around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined. | |
[Marc Slemko] | |
*) The method for determining PATH_INFO has been restored to the pre-1.2b | |
(and NCSA httpd) definition wherein it was the extra path info beyond | |
the CGI script filename. The environment variable FILEPATH_INFO has | |
been removed, and instead we supply the original REQUEST_URI to any | |
script that wants to be Apache-specific and needs the real URI path. | |
This solves a problem with existing scripts that use extra path info | |
in the ScriptAlias directive to pass options to the CGI script. | |
[Roy Fielding] | |
*) The _default_ change in 1.2b10 will change the behaviour on configs | |
that use multiple Listen statements for listening on multiple ports. | |
But that change is necessary to make _default_ consistent with other | |
forms of <VirtualHost>. It requires such configs to be modified | |
to use <VirtualHost _default_:*>. The documentation has been | |
updated. [Dean Gaudet] PR#530 | |
*) If an ErrorDocument CGI script is used to respond to an error | |
generated by another CGI script which has already read the message | |
body of the request, the server would block trying to read the | |
message body again. [Rob Hartill] | |
*) signal() replacement conflicted with a define on QNX (and potentially | |
other platforms). Fixed. [Ben Laurie] PR#512 | |
Changes with Apache 1.2b10 | |
*) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH | |
to be configured via -D in Configuration. [Dean Gaudet] PR#449 | |
*) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet] | |
*) Added prototype for mktemp() for SUNOS4 [Marc Slemko] | |
*) In mod_proxy.c, check return values for proxy_host2addr() when reading | |
config, in case the hostent struct returned is trash. | |
[Chuck Murcko] PR #491 | |
*) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI | |
scripts. [Dean Gaudet, Roy Fielding, Marc Slemko] | |
Changes with Apache 1.2b9 [never announced] | |
*) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port | |
changes and in anticipation of 1.2 final release. [Roy Fielding] | |
*) Fix problem with scripts not receiving a SIGPIPE when client drops | |
the connection (e.g., when user presses Stop). Apache will now stop | |
trying to send a message body immediately after an error from write. | |
[Roy Fielding and Nathan Kurz] PR#335 | |
*) Rearrange Configuration.tmpl so that mod_rewrite has higher priority | |
than mod_alias, and mod_alias has higher priority than mod_proxy; | |
rearranged other modules to enhance understanding of their purpose | |
and relative order (and maybe even reduce some overhead). | |
[Roy Fielding and Sameer Parekh] | |
*) Fix graceful restart. Eliminate many signal-related race | |
conditions in both forms of restart, and in SIGTERM. See | |
htdocs/manual/stopping.html for details on stopping and | |
restarting the parent. [Dean Gaudet] | |
*) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune | |
memory allocator to avoid a behaviour that required extra blocks to | |
be allocated. [Dean Gaudet] | |
*) Allow suexec to access files relative to current directory but not | |
above. (Excluding leading / or any .. directory.) [Ken Coar] | |
PR#269, 319, 395 | |
*) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro] | |
PR#367, 368, 354, 453 | |
*) Fix the above fix: if suexec is enabled, avoid destroying r->url | |
while obtaining the /~user and save the username in a separate data | |
area so that it won't be overwritten by the call to getgrgid(), and | |
fix some misuse of the pool string allocation functions. Also fixes | |
a general problem with parsing URL query info into args for CGI scripts. | |
[Roy Fielding] PR#339, 367, 354, 453 | |
*) Fix IRIX warning about bzero undefined. [Marc Slemko] | |
*) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271 | |
*) Corrected spelling of "authoritative". AuthDBAuthoratative became | |
AuthDBAuthoritative. [Marc Slemko] PR#420 | |
*) MaxClients should be at least 1. [Lars Eilebrecht] PR#375 | |
*) The default handler now logs invalid methods or URIs (i.e. PUT on an | |
object that can't be PUT, or FOOBAR for some method FOOBAR that | |
apache doesn't know about at all). Log 404s that occur in mod_include. | |
[Paul Sutton, John Van Essen] | |
*) If a soft timeout (or lingerout) occurs while trying to flush a | |
buffer or write inside buff.c or fread'ing from a CGI's output, | |
then the timeout would be ignored. [Roy Fielding] PR#373 | |
*) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's | |
parsing of headers. If the terminating empty-line CRLF occurs starting | |
at the 256th or 257th byte of output, then Navigator will think a normal | |
image is invalid. We are guessing that this is because their initial | |
read of a new request uses a 256 byte buffer. We check the bytes written | |
so far and, if we are about to tickle the bug, we instead insert a | |
padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232 | |
*) Fixed SIGSEGV problem when a DirectoryIndex file is also the source | |
of an external redirection. [Roy Fielding and Paul Sutton] | |
*) Configure would create a broken Makefile if the configuration file | |
contained a commented-out Rule. [Roy Fielding] | |
*) Promote per_dir_config and subprocess_env from the subrequest to the | |
main request in mod_negotiation. In particular this fixes a bug | |
where <Files> sections wouldn't properly apply to negotiated content. | |
[Dean Gaudet] | |
*) Fix a potential deadlock in mod_cgi script_err handling. | |
[Ralf S. Engelschall] | |
*) rotatelogs zero-pads the logfile names to improve alphabetic sorting. | |
[Mitchell Blank Jr] | |
*) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within | |
.htaccess files because the RewriteBase was not replaced correctly. | |
Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside | |
<Directory> sections missing a trailing /. [Ralf S. Engelschall] | |
*) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For | |
1.x the settings are those of pre-1.2b8. For 2.x we include | |
USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and | |
HAVE_SYS_RESOURCE_H (enable the RLimit commands). | |
[Dean Gaudet] PR#336, PR#340 | |
*) Redirect did not preserve ?query_strings when present in the client's | |
request. [Dean Gaudet] | |
*) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380 | |
*) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369 | |
*) Add UnixWare compile/install instructions. [Chuck Murcko] | |
*) Add mod_example (illustration of API techniques). [Ken Coar] | |
*) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko] | |
*) Improve handling of directories when filenames have spaces in them. | |
[Chuck Murcko] | |
*) For hosts with multiple IP addresses, try all additional addresses if | |
necessary to get a connect. Fail only if hostent address list is | |
exhausted. [Chuck Murcko] | |
*) More signed/unsigned port fixes. [Dean Gaudet] | |
*) HARD_SERVER_LIMIT can be defined in the Configuration file now. | |
[Dean Gaudet] | |
Changes with Apache 1.2b8 | |
*) suexec.c doesn't close the log file, allowing CGIs to continue writing | |
to it. [Marc Slemko] | |
*) The addition of <Location> and <File> directives made the | |
sub_req_lookup_simple() function bogus, so we now handle | |
the special cases directly. [Dean Gaudet] | |
*) We now try to log where the server is dumping core when a fatal | |
signal is received. [Ken Coar] | |
*) Improved lingering_close by adding a special timeout, removing the | |
spurious log messages, removing the nonblocking settings (they | |
are not needed with the better timeout), and adding commentary | |
about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is | |
now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding] | |
*) Send error messages about setsockopt failures to the server error | |
log instead of stderr. [Roy Fielding] | |
*) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore] | |
*) Stopgap solution for CGI 3-second delay with server-side includes: if | |
processing a subrequest, allocate memory from r->main->pool instead | |
of r->pool so that we can avoid waiting for free_proc_chain to cleanup | |
in the middle of an SSI request. [Dean Gaudet] PR #122 | |
*) Fixed status of response when POST is received for a nonexistent URL | |
(was sending 405, now 404) and when any method is sent with a | |
full-URI that doesn't match the server and the server is not acting | |
as a proxy (was sending 501, now 403). [Roy Fielding] | |
*) Host port changed to unsigned short. [Ken Coar] PR #276 | |
*) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246 | |
*) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet] | |
*) Report extra info from errno with many errors that cause httpd to exit. | |
spawn_child, popenf, and pclosef now have valid errno returns in the | |
event of an error. Correct problems where errno was stomped on | |
before being reported. [Dean Gaudet] | |
*) In the proxy, if the cache filesystem was full, garbage_coll() was | |
never called, and thus the filesystem would remain full indefinitely. | |
We now also remove incomplete cache files left if the origin server | |
didn't send a Content-Length header and either the client has aborted | |
transfer or bwrite() to client has failed. [Petr Lampa] | |
*) Fixed the handling of module and script-added header fields. | |
Improved the interface for sending header fields and reduced | |
the duplication of code between sending okay responses and errors. | |
We now always send both headers_out and err_headers_out, and | |
ensure that the server-reserved fields are not being overridden, | |
while not overriding those that are not reserved. [Roy Fielding] | |
*) Moved transparent content negotiation fields to err_headers_out | |
to reflect above changes. [Petr Lampa] | |
*) Fixed the determination of whether or not we should make the | |
connection persistent for all of the cases where some other part | |
of the server has already indicated that we should not. Also | |
improved the ordering of the test so that chunked encoding will | |
be set whenever it is desired instead of only when KeepAlive | |
is enabled. Added persistent connection capability for most error | |
responses (those that do not indicate a bad input stream) when | |
accessed by an HTTP/1.1 client. [Roy Fielding] | |
*) Added missing timeouts for sending header fields, error responses, | |
and the last chunk of chunked encoding, each of which could have | |
resulted in a process being stuck in write forever. Using soft_timeout | |
requires that the sender check for an aborted connection rather than | |
continuing after an EINTR. Timeouts that used to be initiated before | |
send_http_header (and never killed) are now initiated only within or | |
around the routines that actually do the sending, and not allowed to | |
propagate above the caller. [Roy Fielding] | |
*) mod_auth_anon required an @ or a . in the email address, not both. | |
[Dirk vanGulik] | |
*) per_dir_defaults weren't set correctly until directory_walk for | |
name-based vhosts. This fixes an obscure bug with the wrong config | |
info being used for vhosts that share the same ip as the server. | |
[Dean Gaudet] | |
*) Improved generation of modules/Makefile to be more generic for | |
new module directories. [Ken Coar, Chuck Murcko, Roy Fielding] | |
*) Generate makefile dependency for Configuration based on the actual | |
name given when running the Configure process. [Dean Gaudet] | |
*) Fixed problem with vhost error log not being set prior to | |
initializing virtual hosts. [Dean Gaudet] | |
*) Fixed infinite loop when a trailing slash is included after a type map | |
file URL (extra path info). [Petr Lampa] | |
*) Fixed server status updating of per-connection counters. [Roy Fielding] | |
*) Add documentation for DNS issues (reliability and security), and try | |
to explain the virtual host matching process. [Dean Gaudet] | |
*) Try to continue gracefully by disabling the vhost if a DNS lookup | |
fails while parsing the configuration file. [Dean Gaudet] | |
*) Improved calls to setsockopt. [Roy Fielding] | |
*) Negotiation changes: Don't output empty content-type in variant list; | |
Output charset in variant list; Return sooner from handle_multi() if | |
no variants found; Add handling of '*' wildcard in Accept-Charset. | |
[Petr Lampa and Paul Sutton] | |
*) Fixed overlaying of request/sub-request notes and headers in | |
mod_negotiation. [Dean Gaudet] | |
*) If two variants' charset quality are equal and one is the default | |
charset (iso-8859-1), then prefer the variant that was specifically | |
listed in Accept-Charset instead of the default. [Petr Lampa] | |
*) Memory allocation problem in push_array() -- it would corrupt memory | |
when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding] | |
*) invoke_handler() doesn't handle mime arguments in content-type | |
[Petr Lampa] PR#160 | |
*) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum. | |
[Ken Coar] | |
*) Fixed problem with ErrorDocument not working for virtual hosts | |
due to one of the performance changes in 1.2b7. [Dean Gaudet] | |
*) Log an error message if we get a request header that is too long, | |
since it may indicate a buffer overflow attack. [Marc Slemko] | |
*) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and | |
not reject URLs without a double-slash, as per RFC2068 section 3.2. | |
[Ken Coar] PR #146, #187 | |
*) Added table entry placeholder for new header_parser callback | |
in all of the distributed modules. [Ken Coar] PR #191 | |
*) Allow for cgi files without the .EXE extension on them under OS/2. | |
[Garey Smiley] PR #59 | |
*) Fixed error message when resource is not found and URL contains | |
path info. [Petr Lampa and Dean Gaudet] PR #40 | |
*) Fixed user and server confusion over what should be a virtual host | |
and what is the main server, resulting in access to something | |
other than the name defined in the virtualhost directive (but | |
with the same IP address) failing. [Dean Gaudet] | |
*) Updated mod_rewrite to version 3.0.2, which: fixes compile error on | |
AIX; improves the redirection stuff to enable the users to generally | |
redirect to http, https, gopher and ftp; added TIME variable for | |
RewriteCond which expands to YYYYMMDDHHMMSS strings and added the | |
special patterns >STRING, <STRING and =STRING to RewriteCond, which | |
can be used in conjunction with %{TIME} or other variables to create | |
time-dependent rewriting rules. [Ralf S. Engelschall] | |
*) bpushfd() no longer notes cleanups for the file descriptors it is handed. | |
Module authors may need to adjust their code for proper cleanup to take | |
place (that is, call note_cleanups_for_fd()). This change fixes problems | |
with file descriptors being erroneously closed when the proxy module was | |
in use. [Ben Laurie] | |
*) Fix bug in suexec reintroduced by changes in 1.2b7 which allows | |
initgroups() to hose the group information needed for later | |
comparisons. [Randy Terbush] | |
*) Remove unnecessary call to va_end() in create_argv() which | |
caused a SEGV on some systems. | |
*) Use proper MAXHOSTNAMELEN symbol for limiting length of server name. | |
[Dean Gaudet] | |
*) Clear memory allocated for listeners. [Randy Terbush] | |
*) Improved handling of IP address as a virtualhost address and | |
introduced "_default_" as a synonym for the default vhost config. | |
[Dean Gaudet] PR #212 | |
Changes with Apache 1.2b7 | |
*) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>] | |

- replace protocol response numbers with symbols | |
- save variant-list into main request notes | |
- free allocated memory from subrequests | |

*) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to | |
"HTTP/#.# ###*" to be more lenient about what we accept. | |
[Chuck Murcko] | |
*) more proxy FTP bug fixes: | |
- Changed send_dir() to remove user/passwd from displayed URL. | |
- Changed login error messages to be more descriptive. | |
- remove setting of SO_DEBUG socket option | |
- Make ftp_getrc() more lenient about multiline responses, | |
specifically, 230 responses which don't have continuation 230- | |
on each line). These seem to be all NT FTP servers, and while | |
perhaps questionable, they appear to be legal by RFC 959. | |
- Add missing kill_timeout() after transfer to user completes. | |
[Chuck Murcko] | |
*) Fixed problem where a busy server could hang when restarting | |
after being sent a SIGHUP due to child processes not exiting. | |
[Marc Slemko] | |
*) Modify mod_include escaping so a '\' only signifies an escaped | |
character if the next character is one that needs | |
escaping. [Ben Laurie] | |
*) Eliminated possible infinite loop in mod_imap when relative URLs are | |
used with a 'base' directive that does not have a '/' in it. | |
[Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>] | |
*) Reduced the default timeout from 1200 seconds to 300, and the | |
one in the sample configfile from 400 to 300. [Marc Slemko] | |
*) Stop vbprintf from crashing if given a NULL string pointer; | |
print (null) instead. [Ken Coar] | |
*) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY. | |
[Marc Slemko and Roy Fielding] | |
*) Fixed problem with mod_cgi-generated internal redirects trying to | |
read the request message-body twice. [Archie Cobbs and Roy Fielding] | |
*) Reduced timeout on lingering close, removed possibility of a blocked | |
read causing the child to hang, and stopped logging of errors if | |
the socket is not connected (reset by client). [Roy Fielding] | |
*) Rearranged main child loop to remove duplication of code in | |
select/accept and keep-alive requests, fixed several bugs regarding | |
checking scoreboard_image for exit indication and failure to | |
account for all success conditions and trap all error conditions, | |
prevented multiple flushes before closing the socket; close the entire | |
socket buffer instead of just one descriptor, prevent logging of | |
EPROTO and ECONNABORTED on platforms where supported, and generally | |
improved readability. [Roy Fielding] | |
*) Extensive performance improvements. Cleaned up inefficient use of | |
auto initializers, multiple is_matchexp calls on a static string, | |
and excessive merging of response_code_strings. [Dean Gaudet] | |
*) Added double-buffering to mod_include to improve performance on | |
server-side includes. [Marc Slemko] | |
*) Several fixes for suexec wrapper. [Randy Terbush] | |
- Make wrapper work for files on NFS filesystem. | |
- Fix portability problem of MAXPATHLEN. | |
- Fix array overrun problem in clean_env(). | |
- Fix allocation of PATH environment variable | |
*) Removed extraneous blank line is description of mod_status chars. | |
[Kurt Kohler] | |
*) Logging of errors from the call_exec routine simply went nowhere, | |
since the logfile fd has been closed, so now we send them to stderr. | |
[Harald T. Alvestrand] | |
*) Fixed core dump when DocumentRoot is a CGI. | |
[Ben Laurie, reported by <geddis tesserae.com>] | |
*) Fixed potential file descriptor leak in mod_asis; updated it and | |
http_core to use pfopen/pfclose instead of fopen/fclose. | |
[Randy Terbush and Roy Fielding] | |
*) Fixed handling of unsigned ints in ap_snprintf() on some chips such | |
as the DEC Alpha which is 64-bit but uses 32-bit ints. | |
[Dean Gaudet and Ken Coar] | |
*) Return a 302 response code to the client when sending a redirect | |
due to a missing trailing '/' on a directory instead of a 301; now | |
it is cacheable. [Markus Gyger] | |
*) Fix condition where, if a bad directive occurs in .htaccess, and | |
sub_request() goes first to this directory, then log_reason() will | |
SIGSEGV because it doesn't have initialized r->per_dir_config. | |
[PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet] | |
*) Fix handling of lang_index in is_variant_better(). This was | |
causing problems which resulted in the server sending the | |
wrong language document in some cases. [Petr Lampa] | |
*) Remove free() from clean_env() in suexec wrapper. This was nuking | |
the clean environment on some systems. | |
*) Tweak byteserving code (e.g. serving PDF files) to work around | |
bugs in Netscape Navigator and Microsoft Internet Explorer. | |
Emit Content-Length header when sending multipart/byteranges. | |
[Alexei Kosut] | |
*) Port to HI-UX/WE2. [Nick Maclaren] | |
*) Port to HP MPE operating system for HP 3000 machines | |
[Mark Bixby <markb cccd.edu>] | |
*) Fixed bug which caused a segmentation fault if only one argument | |
given to RLimit* directives. [Ed Korthof] | |
*) Continue persistent connection after 204 or 304 response. [Dean Gaudet] | |
*) Improved buffered output to the client by delaying the flush decision | |
until the BUFF code is actually about to read the next request. | |
This fixes a problem introduced in 1.2b5 with clients that send | |
an extra CRLF after a POST request. Also improved chunked output | |
performance by combining writes using writev() and removing as | |
many bflush() calls as possible. NOTE: Platforms without writev() | |
must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration | |
or Configure, unless we have already done so. [Dean Gaudet] | |
*) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko] | |
*) Fixed mod_info output corruption bug introduced by buffer overflow | |
fixes. [Dean Gaudet] | |
*) Fixed http_protocol to correctly output all HTTP/1.1 headers, including | |
for the special case of a 304 response. [Paul Sutton] | |
*) Improved handling of TRACE method by bypassing normal method handling | |
and header parsing routines; fixed Allow response to always allow TRACE. | |
[Dean Gaudet] | |
*) Fixed compiler warnings in the regex library. [Dean Gaudet] | |
*) Cleaned-up some of the generated HTML. [Ken Coar] | |
Changes with Apache 1.2b6 | |
*) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko] | |
*) Fix typo introduced in fix for potential infinite loop around | |
accept() in child_main(). This change caused the rev to 1.2b6. | |
1.2b5 was never a public beta. | |
Changes with Apache 1.2b5 | |
*) Change KeepAlive semantics (On|Off instead of a number), add | |
MaxKeepAliveRequests directive. [Alexei Kosut] | |
*) Various NeXT compilation patches, as well as a change in | |
regex/regcomp.c since that file also used a NEXT define. | |
[Andreas Koenig] | |
*) Allow * to terminate the end of a directory match in mod_dir. | |
Allows /~* to match for both /~joe and /~joe/. [David Bronder] | |
*) Don't call can_exec() if suexec_enabled. Calling this requires | |
scripts executed by the suexec wrapper to be world executable, which | |
defeats one of the advantages of running the wrapper. [Randy Terbush] | |
*) Portability Fix: IRIX complained with 'make clean' about *pure* (removed) | |
[Jim Jagielski] | |
*) Migration from sprintf() to snprintf() to avoid buffer | |
overflows. [Marc Slemko] | |
*) Provide portable snprintf() implementation (ap_snprintf) | |
as well as *cvt family. [Jim Jagielski] | |
*) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion | |
[Jim Jagielski] | |
*) Remove mod_fastcgi.c from the distribution. This module appears | |
to be maintained more through the Open Market channels and should | |
continue to be easily available at http://www.fastcgi.com/ | |
*) Fixed bug in modules/Makefile that wouldn't allow building in more | |
than one subdirectory (or cleaning, either). [Jeremy Laidman] | |
*) mod_info assumed that the config files were relative to ServerRoot. | |
[Ken the Rodent] | |
*) CGI scripts called as an error document resulting from failed | |
CGI execution would hang waiting for POST'ed data. [Rob Hartill] | |
*) Log reason when mod_dir returns access HTTP_FORBIDDEN | |
[Ken the Rodent] | |
*) Properly check errno to prevent display of a directory index | |
when server receives a long enough URL to confuse stat(). | |
[Marc Slemko] | |
*) Several security enhancements to suexec wrapper. It is _highly_ | |
recommended that previously installed versions of the wrapper | |
be replaced with this version. [Randy Terbush, Jason Dour] | |
- ~user execution now properly restricted to ~user's home | |
directory and below. | |
- execution restricted to UID/GID > 100 | |
- restrict passed environment to known variables | |
- call setgid() before initgroups() (portability fix) | |
- remove use of setenv() (portability fix) | |
*) Add HTTP/1.0 response forcing. [Ben Laurie] | |
*) Add access control via environment variables. [Ben Laurie] | |
*) Add rflush() function. [Alexei Kosut] | |
*) remove duplicate pcalloc() call in new_connection(). | |
*) Fix incorrect comparison which could allow number of children = | |
MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential | |
problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof] | |
*) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD | |
AIX PS/2, CONVEXOS. [Jim Jagielski] | |
*) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock. | |
It's more portable. [Martin Kraemer] | |
*) Replace references to make in Makefile.tmpl with $(MAKE). | |
[Chuck Murcko] | |
*) Add ProxyBlock directive w/IP address caching. Add IP address | |
caching to NoCache directive as well. ProxyBlock works with all | |
handlers; NoCache now also works with FTP for anonymous logins. | |
Still more code cleanup. [Chuck Murcko] | |
*) Add "header parse" API hook [Ben Laurie] | |
*) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko] | |
*) suEXEC wrapper was freeing memory that had not been malloc'ed. | |
*) Correctly allow access and auth directives in <Files> sections in | |
server config files. [Alexei Kosut] | |
*) Fix bug with ServerPath that could cause certain files to be not | |
found by the server. [Alexei Kosut] | |
*) Fix handling of ErrorDocument so that it doesn't remove a trailing | |
double-quote from text and so that it properly checks for unsupported | |
status codes using the new index_of_response interface. [Roy Fielding] | |
*) Multiple fixes to the lingering_close code in order to avoid being | |
interrupted by a stray timeout, to avoid lingering on a connection | |
that has already been aborted or never really existed, to ensure that | |
we stop lingering as soon as any error condition is received, and to | |
prevent being stuck indefinitely if the read blocks. Also improves | |
reporting of error conditions. [Marc Slemko and Roy Fielding] | |
*) Fixed initialization of parameter structure for sigaction. | |
[<mgyger itr.ch>, Adrian Filipi-Martin] | |
*) Fixed reinitializing the parameters before each call to accept and | |
select, and removed potential for infinite loop in accept. | |
[Roy Fielding, after useful PR from <adrian virginia.edu>] | |
*) Fixed condition where, if a child fails to fork, the scoreboard would | |
continue to say SERVER_STARTING forever. Eventually, the main process | |
would refuse to start new children because count_idle_servers() will | |
count those SERVER_STARTING entries and will always report that there | |
are enough idle servers. [Phillip Vandry] | |
*) Fixed bug in bcwrite regarding failure to account for partial writes. | |
Avoided calling bflush() when the client is pipelining requests. | |
Removed unnecessary flushes from http_protocol. [Dean Gaudet] | |
*) Added description of "." mode in server-status [Jim Jagielski] | |
Changes with Apache 1.2b4 | |
*) Fix possible race condition in accept_mutex_init() that | |
could leave a small security hole open allowing files to be | |
overwritten in cases where the server UID has write permissions. | |
[Marc Slemko] | |
*) Fix awk compatibilty problem in Configure. [Jim Jagielski] | |
*) Fix portablity problem in util_script where ARG_MAX may not be | |
defined for some systems. | |
*) Add changes to allow compilation on Machten 4.0.3 for PowerPC. | |
[Randal Schwartz] | |
*) OS/2 changes to support an MMAP style scoreboard file and UNIX | |
style magic #! token for better script portability. [Garey Smiley] | |
*) Fix bug in suexec wrapper introduced in b3 that would cause failed | |
execution for ~userdir CGI. [Jason Dour] | |
*) Fix initgroups() business in suexec wrapper. [Jason Dour] | |
*) Fix month off by one in suexec wrapper logging. | |
Changes with Apache 1.2b3: | |
*) Fix error in mod_cgi which could cause resources not to be properly | |
freed, or worse. [Dean Gaudet] | |
*) Fix find_string() NULL pointer dereference. [Howard Fear] | |
*) Add set_flag_slot() at the request of Dirk and others. | |
[Dirk vanGulik] | |
*) Sync mod_rewrite with patch level 10. [Ralf Engelschall] | |
*) Add changes to improve the error message given for invalid | |
ServerName parameters. [Dirk vanGulik] | |
*) Add "Authoritative" directive for Auth modules that don't | |
currently have it. This gives admin control to assign authoritative | |
control to an authentication scheme and allow "fall through" for | |
those authentication modules that aren't "Authoritative" thereby | |
allowing multiple authentication mechanisms to be chained. | |
[Dirk vanGulik] | |
*) Remove requirement for ResourceConfig/AccessConfig if not using | |
the three config file layout. [Randy Terbush] | |
*) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko] | |
*) Changes to suexec wrapper to fix the following problems: | |
1. symlinked homedirs will kill ~userdirs. | |
2. initgroups() on Linux 2.0.x clobbers gr->grid. | |
3. CGI command lines paramters problems | |
4. pw-pwdir for "docroot check" still the httpd user's pw record. | |
[Randy Terbush, Jason Dour] | |
*) Change create_argv() to accept variable arguments. This fixes | |
a problem where arguments were not getting passed to the CGI via | |
argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz] | |
*) Collapse multiple slashes in path URLs to properly apply | |
handlers defined by <Location>. [Alexei Kosut] | |
*) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX. | |
*) Improve the accuracy of request duration timings by setting | |
r->request_time in read_request_line() instead of read_request(). | |
[Dean Gaudet] | |
*) Reset timeout while reading via get_client_block() in mod_cgi.c | |
Fixes problem with timed out transfers of large files. [Rasmus Lerdorf] | |
*) Add the ability to pass different Makefile.tmpl files to Configure | |
using the -make flag. [Rob Hartill] | |
*) Fix coredump triggered when sending a SIGHUP to the server caused | |
by an assertion failure, in turn caused by an uninitialised field in a | |
listen_rec. | |
[Ben Laurie] | |
*) Add FILEPATH_INFO variable to CGI environment, which is equal to | |
PATH_INFO from previous versions of Apache (in certain situations, | |
Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut] | |
[later removed in 1.2b11] | |
*) Add rwrite() function to API to allow for sending strings of | |
arbitrary length. [Doug MacEachern] | |
*) Remove rlim_t typedef for NetBSD. Do older versions need this? | |
*) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for | |
NeXT. [Jim Jagielski] | |
*) Removed recent modification to promote the status code on internal | |
redirects, since the correct fix was to change the default log format | |
in mod_log_config so that it outputs the original status. [Rob Hartill] | |
Changes with Apache 1.2b2: | |
*) Update set_signals() to use sigaction() for setting handlers. | |
This appears to fix a re-entrant problem in the seg_fault() | |
bus_error() handlers. [Randy Terbush] | |
*) Changes to allow mod_status compile for OS/2 [Garey Smiley] | |
*) changes for DEC AXP running OSF/1 v3.0. [Marc Evans] | |
*) proxy_http.c bugfixes: [Chuck Murcko] | |
1) fixes possible NULL pointer reference w/NoCache | |
2) fixes NoCache behavior when using ProxyRemote (ProxyRemote | |
host would cache nothing if it was in the local domain, | |
and the local domain was in the NoCache list) | |
3) Adds Host: header when not available | |
4) Some code cleanup and clarification | |
*) mod_include.c bugfixes: | |
1) Fixed an ommission that caused include variables to not | |
be parsed in config errmsg directives [Howard Fear] | |
2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut] | |
3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>] | |
4) Allow backslash-escaping to all quoted text | |
[Ben Yoshino <ben wiliki.eng.hawaii.edu>] | |
5) Pass variable to command line if not set in XSSI's env | |
[Howard Fear] | |
*) Fix infinite loop when processing Content-language lines in | |
type-map files. [Alexei Kosut] | |
*) Closed file-globbing hole in test-cgi script. [Brian Behlendorf] | |
*) Fixed problem in set_[user|group] that prevented CGI execution | |
for non-virtualhosts when suEXEC was enabled. [Randy Terbush] | |
*) Added PORTING information file. [Jim Jagielski] | |
*) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie] | |
*) Changed default group to "nogroup" instead of "nobody" [Randy Terbush] | |
*) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where | |
USE_FCNTL_SERIALIZED_ACCEPT was intended. | |
*) Fixed additional uses of 0xffffffff where INADDR_NONE was intended, | |
which caused problems of systems where socket s_addr is >32bits. | |
*) Added comment to explain (r->chunked = 1) side-effect in | |
http_protocol.c [Roy Fielding] | |
*) Replaced use of index() in mod_expires.c with more appropriate | |
and portable isdigit() test. [Ben Laurie] | |
*) Updated Configure for ... | |
OS/2 (DEF_WANTHSREGEX=yes, other code changes) | |
*-dg-dgux* (bad pattern match) | |
QNX (DEF_WANTHSREGEX=yes) | |
*-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY) | |
*-ultrix (new) | |
*-unixware211 (new) | |
and added some user diagnostic info. [Ben Laurie] | |
*) In helpers/CutRule, replaced "cut" invocation with "awk" invocation | |
for better portability. [Jim Jagielski] | |
*) Updated helpers/GuessOS for ... | |
SCO 5 (recognize minor releases) | |
SCO UnixWare (braindamaged uname, whatever-whatever-unixware2) | |
SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h) | |
IRIX64 (-sgi-irix64) | |
ULTRIX (-unknown-ultrix) | |
SINIX (-whatever-sysv4) | |
NCR Unix (-ncr-sysv4) | |
and fixed something in helpers/PrintPath [Ben Laurie] | |
Changes with Apache 1.2b1 | |
*) Not listed. See <http://www.apache.org/docs/new_features_1_2.html> | |
Changes with Apache 1.1.1 | |
*) Fixed bug where Cookie module would make two entries in the | |
logfile for each access [Mark Cox] | |
*) Fixed bug where Redirect in .htaccess files would cause memory | |
leak. [Nathan Neulinger] | |
*) MultiViews now works correctly with AddHandler [Alexei Kosut] | |
*) Problems with mod_auth_msql fixed [Dirk vanGulik] | |
*) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon. | |
Changes with Apache 1.1.0 | |
*) Bring NeXT support up to date. [Takaaki Matsumoto] | |
*) Bring QNX support up to date. [Ben Laurie] | |
*) Make virtual hosts default to main server keepalive parameters. | |
[Alexei Kosut, Ben Laurie] | |
*) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut] | |
*) Fix missing address family for connect, also remove unreachable statement | |
in mod_proxy. [Ben Laurie] | |
*) mod_env now turned on by default in Configuration.tmpl. | |
*) Bugs which were fixed: | |
a) yet more mod_proxy bugs [Ben Laurie] | |
b) CGI works again with inetd [Alexei Kosut] | |
c) Leading colons were stripped from passwords [<osm interguide.com>] | |
d) Another fix to multi-method Limit problem [<jk tools.de>] | |
Changes with Apache 1.1b4 | |
*) r->bytes_sent variable restored. [Robert Thau] | |
*) Previously broken multi-method <Limit> parsing fixed. [Robert Thau] | |
*) More possibly unsecure programs removed from the support directory. | |
*) More mod_auth_msql authentication improvements. | |
*) VirtualHosts based on Host: headers no longer conflict with the | |
Listen directive. | |
*) OS/2 compatibility enhancements. [Gary Smiley] | |
*) POST now allowed to directory index CGI scripts. | |
*) Actions now work with files of the default type. | |
*) Bugs which were fixed: | |
a) more mod_proxy bugs | |
b) early termination of inetd requests | |
c) compile warnings on several systems | |
d) problems when scripts stop reading output early | |
Changes with Apache 1.1b3 | |
*) Much of cgi-bin and all of cgi-src has been removed, due to | |
various security holes found and that we could no longer support | |
them. | |
*) The "Set-Cookie" header is now special-cased to not merge multiple | |
instances, since certain popular browsers can not handle multiple | |
Set-Cookie instructions in a single header. [Paul Sutton] | |
*) rprintf() added to buffer code, occurrences of sprintf removed. | |
[Ben Laurie] | |
*) CONNECT method for proxy module, which means tunneling SSL should work. | |
(No crypto needed) Also a NoCache config directive. | |
*) Several API additions: pstrndup(), table_unset() and get_token() | |
functions now available to modules. | |
*) mod_imap fixups, in particular Location: headers are now complete | |
URL's. | |
*) New "info" module which reports on installed module set through a | |
special URL, a la mod_status. | |
*) "ServerPath" directive added - allows for graceful transition | |
for Host:-header-based virtual hosts. | |
*) Anonymous authentication module improvements. | |
*) MSQL authentication module improvements. | |
*) Status module design improved - output now table-based. [Ben Laurie] | |
*) htdigest utility included for use with digest authentication | |
module. | |
*) mod_negotiation: Accept values with wildcards to be treated with | |
less priority than those without wildcards at the same quality | |
value. [Alexei Kosut] | |
*) Bugs which were fixed: | |
a) numerous mod_proxy bugs | |
b) CGI early-termination bug [Ben Laurie] | |
c) Keepalives not working with virtual hosts | |
d) RefererIgnore problems | |
e) closing fd's twice in mod_include (causing core dumps on | |
Linux and elsewhere). | |
Changes with Apache 1.1b2 | |
*) Bugfixes: | |
a) core dumps in mod_digest | |
b) truncated hostnames/ip address in the logs | |
c) relative URL's in mod_imap map files | |
Changes with Apache 1.1b1 | |
*) Not listed. See <http://www.apache.org/docs/new_features_1_1.html> | |
Changes with Apache 1.0.3 | |
*) Internal redirects which occur in mod_dir.c now preserve the | |
query portion of a request (the bit after the question mark). | |
[Adam Sussman] | |
*) Escape active characters '<', '>' and '&' in html output in | |
directory listings, error messages and redirection links. | |
[David Robinson] | |
*) Apache will now work with LynxOS 2.3 and later [Steven Watt] | |
*) Fix for POSIX compliance in waiting for processes in alloc.c. | |
[Nick Williams] | |
*) setsockopt no longer takes a const declared argument [Martijn Koster] | |
*) Reset timeout timer after each successful fwrite() to the network. | |
This patch adds a reset_timeout() procedure that is called by | |
send_fd() to reset the timeout ever time data is written to the net. | |
[Nathan Schrenk] | |
*) timeout() signal handler now checks for SIGPIPE and reports | |
lost connections in a more user friendly way. [Rob Hartill] | |
*) Location of the "scoreboard" file which used to live in /tmp is | |
now configurable (for OSes that can't use mmap) via ScoreBoardFile | |
which works similar to PidFile (in httpd.conf) [Rob Hartill] | |
*) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh] | |
*) the pstrcat call in mod_cookies.c didn't have an ending NULL, | |
which caused a SEGV with cookies enabled | |
*) Output warning when MinSpareServers is set to <= 0 and change it to 1 | |
[Rob Hartill] | |
*) Log the UNIX textual error returned by some system calls, in | |
particular errors from accept() [David Robinson] | |
*) Add strerror function to util.c for SunOS4 [Randy Terbush] | |
Changes with Apache 1.0.2 | |
*) patch to get Apache compiled on UnixWare 2.x, recommended as | |
a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko] | |
*) Fix get_basic_auth_pw() to set the auth_type of the request. | |
[David Robinson] | |
*) past changes to http_config.c to only use the | |
setrlimit function on systems defining RLIMIT_NOFILE | |
broke the feature on SUNOS4. Now defines HAVE_RESOURCE | |
for SUNOS and prototypes the needed functions. | |
*) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines. | |
[David Robinson] | |
*) Fix use of pointer to scratch memory. [Cliff Skolnick] | |
*) Merge multiple headers from CGI scripts instead of taking last | |
one. [David Robinson] | |
*) Add support for SCO 5. [Ben Laurie] | |
Changes with Apache 1.0.1 | |
*) Silence mod_log_referer and mod_log_agent if not configured | |
[Randy Terbush] | |
*) Recursive includes can occur if the client supplies PATH_INFO data | |
and the server provider uses relative links; as file.html | |
relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson] | |
*) The replacement for initgroups() did not call {set,end}grent(). This | |
had two implications: if anything else used getgrent(), then | |
initgroups() would fail, and it was consuming a file descriptor. | |
[Ben Laurie] | |
*) On heavily loaded servers it was possible for the scoreboard to get | |
out of sync with reality, as a result of a race condition. | |
The observed symptoms are far more Apaches running than should | |
be, and heavy system loads, generally followed by catastrophic | |
system failure. [Ben Laurie] | |
*) Fix typo in license. [David Robinson] | |
Changes with Apache 1.0.0 23 Nov 1995 | |
*) Not listed. See <http://www.apache.org/docs/new_features_1_0.html> | |
Changes with Apache 0.8.16 05 Nov 1995 | |
*) New man page for 'httpd' added to support directory [David Robinson] | |
*) .htgroup files can have more than one line giving members for a | |
given group (each must have the group name in front), for NCSA | |
back-compatibility [Robert Thau] | |
*) Mutual exclusion around accept() is on by default for SVR4 systems | |
generally, since they generally can't handle multiple processes in | |
accept() on the same socket. This should cure flaky behavior on | |
a lot of those systems. [David Robinson] | |
*) AddType, AddEncoding, and AddLanguage directives take multiple | |
extensions on a single command line [David Robinson] | |
*) UserDir can be disabled for a given virtual host by saying | |
"UserDir disabled" in the <VirtualHost> section --- it was a bug | |
that this didn't work. [David Robinson] | |
*) Compiles on QNX [Ben Laurie] | |
*) Corrected parsing of ctime time format [David Robinson] | |
*) httpd does a perror() before exiting if it can't log its pid | |
to the PidFile, to make diagnosing the error a bit easier. | |
[David Robinson] | |
*) <!--#include file="..."--> can no longer include files in the | |
parent directory, for NCSA back-compatibility. [David Robinson] | |
*) '~' is *not* escaped in URIs generated for directory listings | |
[Roy Fielding] | |
*) Eliminated compiler warning in the imagemap module [Randy Terbush] | |
*) Fixed bug involving handling URIs with escaped %-characters | |
in redirects [David Robinson] | |
Changes with Apache 0.8.15 14 Oct 1995 | |
*) Switched to new, simpler license | |
*) Eliminated core dumps with improperly formatted DBM group files [Mark Cox] | |
*) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie] | |
*) Reject paths containing %-escaped '%' or null characters [David Robinson] | |
*) Correctly handles internal redirects to files with names containing '%' | |
[David Robinson] | |
*) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson] | |
*) Use geteuid() rather than getuid() to see if we have root privilege, | |
so that server correctly resets privilege if run setuid root. [Andrew | |
Wilson] | |
*) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module) | |
[Randy Terbush] | |
*) Fix relative URLs in imagemap files [Randy Terbush] | |
*) Somewhat better fix for the old "Alias /foo/ /bar/" business | |
[David Robinson] | |
*) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost> | |
entries all name the same one. [David Robinson] | |
*) Fix directory listings with filenames containing unusual characters | |
[David Robinson] | |
*) Better URI-escaping for generated URIs in directories with filenames | |
containing unusual characters [Ben Laurie] | |
*) Fixed potential FILE* leak in http_main.c [Ben Laurie] | |
*) Unblock alarms on error return from spawn_child() [David Robinson] | |
*) Sample Config files have extra note for SCO users [Ben Laurie] | |
*) Configuration has note for HP-UX users [Rob Hartill] | |
*) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh] | |
*) Nuked bogus #define in httpd.h [David Robinson] | |
*) Better test for whether a system has setrlimit() [David Robinson] | |
*) Calls update_child_status() after reopen_scoreboard() [David Robinson] | |
*) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode | |
[Ben Laurie] | |
Changes with Apache 0.8.14 19 Sep 1995 | |
*) Compiles on SCO ODT 3.0 [Ben Laurie] | |
*) AddDescription works (better) [Ben Laurie] | |
*) Leaves an intelligible error diagnostic when it can't set group | |
privileges on standalone startup [Andrew Wilson] | |
*) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on | |
that machine, which claims to be BSD but does not support RLIMIT. | |
[Randy Terbush] | |
*) gcc -Wall no longer complains about an unused variable when util.c | |
is compiled with -DMINIMAL_DNS [Andrew Wilson] | |
*) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh] | |
Changes with Apache 0.8.13 07 Sep 1995 | |
*) Make IndexIgnore *work* (ooops) [Jarkko Torppa] | |
*) Have built-in imagemap code recognize & honor Point directive [James | |
Cloos] | |
*) Generate cleaner directory listings in directories with a mix of | |
long and short filenames [Rob Hartill] | |
*) Properly initialize dynamically loaded modules [Royston Shufflebotham] | |
*) Properly default ServerName for virtual servers [Robert Thau] | |
*) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush, | |
Paul Richards and a cast of thousands...] | |
*) On self-identified BSD systems (we don't try to guess any more), | |
allocate a few extra file descriptors per virtual host with setrlimit, | |
if we can, to avoid running out. [Randy Terbush] | |
*) Write 22-character lock file name into buffer with enough space | |
on startup [Konstantin Olchanski] | |
*) Use archaic setpgrp() interface on NeXT, which requires it [Brian | |
Pinkerton] | |
*) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh] | |
*) Suppress -Wall warning by initializing variable in negotiation code | |
[Tobias Weingartner] | |
Changes with Apache 0.8.12 31 Aug 1995 | |
*) Doesn't pause three seconds after including a CGI script which is | |
too slow to die off (this is done by not even trying to kill off | |
subprocesses, including the SIGTERM/pause/SIGKILL routine, until | |
after the entire document has been processed). [Robert Thau] | |
*) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson] | |
*) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding] | |
*) Allows .htaccess files to override <Directory> sections naming the | |
same directory [David Robinson] | |
*) Removed an efficiency hack in sub_req_lookup_uri which was | |
causing certain extremely marginal cases (e.g., ScriptAlias of a | |
*particular* index.html file) to fail. [David Robinson] | |
*) Doesn't log an error when the requested URI requires | |
authentication, but no auth header line was supplied by the | |
client; this is a normal condition (the client doesn't no auth is | |
needed here yet). [Robert Thau] | |
*) Behaves more sanely when the name server loses its mind [Sean Welch] | |
*) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush] | |
*) RFC931 code no longer passes out name of prior clients on current | |
requests if the current request came from a server that doesn't | |
do RFC931. [David Robinson] | |
*) Configuration script accepts "Module" lines with trailing whitespace. | |
[Robert Thau] | |
*) Cleaned up compiler warning from mod_access.c [Robert Thau] | |
*) Cleaned up comments in mod_cgi.c [Robert Thau] | |
Changes with Apache 0.8.11 24 Aug 1995 | |
*) Wildcard <Directory> specifications work. [Robert Thau] | |
*) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick] | |
*) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check | |
the file being requested itself, in addition to the directories leading | |
up to it. [Robert Thau] | |
*) Logs access failures due to symlink checks or invalid client address | |
in the error log [Roy Fielding, Robert Thau] | |
*) Symlink checks deal correctly with systems where lstat of | |
"/path/to/some/link/" follows the link. [Thau, Fielding] | |
*) Doesn't reset DirectoryIndex to 'index.html' when | |
other directory options are set in a .htaccess file. [Robert Thau] | |
*) Clarified init code and nuked bogus warning in mod_access.c | |
[Florent Guillaume] | |
*) Corrected several directives in sample srm.conf | |
--- includes corrections to directory indexing icon-related directives | |
(using unknown.gif rather than unknown.xbm as the DefaultIcon, doing | |
icons for encodings right, and turning on AddEncoding by default). | |
[Roy Fielding] | |
*) Corrected descriptions of args to AddIcon and AddAlt in command table | |
[James Cloos] | |
*) INSTALL & README mention "contributed modules" directory [Brian | |
Behlendorf] | |
*) Fixed English in the license language... "for for" --> "for". | |
[Roy Fielding] | |
*) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to | |
mod_alias.c, merging it almost completely with handling of Alias, and | |
adding a 'notes' field to the request_rec which allows the CGI module | |
to discover whether the Alias module has put this request through | |
ScriptAlias (which it needs to know for back-compatibility, as the old | |
NCSA code did not check Options ExecCGI in ScriptAlias directories). | |
[Robert Thau] | |
Changes with Apache 0.8.10 18 Aug 1995 | |
*) AllowOverride applies to the named directory, and not just | |
subdirectories. [David Robinson] | |
*) Do locking for accept() exclusion (on systems that need it) | |
using a special file created for the purpose in /usr/tmp, and | |
not the error log; using the error log causes real problems | |
if it's NFS-mounted; this is known to be the cause of a whole | |
lot of "server hang" problems with Solaris. [David Robinson; | |
thanks to Merten Schumann for help diagnosing the problem]. | |
Changes with Apache 0.8.9 12 Aug 1995 | |
*) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen] | |
*) Nested includes see environment variables of the including document, | |
for NCSA bug-compatibility (some sites have standard footer includes | |
which try to print out the last-modified date). [Eric Hagberg/Robert | |
Thau] | |
*) <!--exec cgi="/some/uri/here"--> always treats the item named by the | |
URI as a CGI script, even if it would have been treated as something | |
else if requested directly, for NCSA back-compatibility. (Note that | |
this means that people who know the name of the script can see the | |
code just by asking for it). [Robert Thau] | |
*) New version of dbmmanage script included in support directory as | |
dbmmanage.new. | |
*) Check if scoreboard file couldn't be opened, and say so, rather | |
then going insane [David Robinson] | |
*) POST to CGI works on A/UX [Jim Jagielski] | |
*) AddIcon and AddAlt commands work properly [Rob Hartill] | |
*) NCSA server push works properly --- the Arena bug compatibility | |
workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND | |
if you still want the workaround). [Rob Hartill] | |
*) If client didn't submit any Accept-encodings, ignore encodings in | |
content negotiation. (NB this will all have to be reworked anyway | |
for the new HTTP draft). [Florent Guillaume] | |
*) Don't dump core when trying to log timed-out requests [Jim Jagielski] | |
*) Really honor CacheNegotiatedDocs [Florent Guillaume] | |
*) Give Redirect priority over Alias, for NCSA bug compatibility | |
[David Robinson] | |
*) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->, | |
paralleling earlier bug fix for CGI [David Robinson] | |
*) If DBM auth is improperly configured, report a server error and don't | |
dump core. | |
*) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX; | |
it seems to work well enough without it (even in a 10 hits/sec | |
workout), and the overhead for the locking under A/UX is | |
alarmingly high (though it is very low on other systems). | |
[Eric Hagberg, Jim Jagielski] | |
*) Fixed portability problems with mod_cookies.c [Cliff Skolnick] | |
*) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian | |
Behlendorf/Eric Hagberg] | |
*) More improvements to default Configuration for A/UX [Jim Jagielski] | |
*) Compiles clean on NEXT [Rob Hartill] | |
*) Compiles clean on SGI [Robert Thau] | |
Changes with Apache 0.8.8 08 Aug 1995 | |
*) SunOS library prototypes now never included unless explicitly | |
requested in the configuration (via -DSUNOS_LIB_PROTOTYPES); | |
people using GNU libc on SunOS are screwed by prototypes for the | |
standard library. | |
(Those who wish to compile clean with gcc -Wall on a standard | |
SunOS setup need the prototypes, and may obtain them using | |
-DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system | |
with nonstandard libraries are presumably competent to make their | |
own arrangements). | |
*) Strips trailing '/' characters off both args to the Alias command, | |
to make 'Alias /foo/ /bar/' work. | |
Changes with Apache 0.8.7 03 Aug 1995 | |
*) Don't hang when restarting with a child from 'TransferLog "|..."' running | |
[reported by David Robinson] | |
*) Compiles clean on OSF/1 [David Robinson] | |
*) Added some of the more recent significant changes (AddLanguage stuff, | |
experimental LogFormat support) to CHANGES file in distribution root | |
directory | |
Changes with Apache 0.8.6 02 Aug 1995 | |
*) Deleted Netscape reload workaround --- it's in violation of HTTP specs. | |
(If you actually wanted a conditional GET which bypassed the cache, you | |
couldn't get it). [Reported by Roy Fielding] | |
*) Properly terminate headers on '304 Not Modified' replies to conditional | |
GETs --- no browser we can find cares much, but the CERN proxy chokes. | |
[Reported by Cliff Skolnick; fix discovered independently by Rob Hartill] | |
*) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko] | |
*) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__, | |
not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em, | |
and older versions don't set the __SUNPRO_C preprocessor variable). On | |
all other systems, these are never used anyway. [Reported by Mark Cox]. | |
*) Scoreboard file (/tmp/htstatus.*) no longer publically writable. | |
Changes with Apache 0.8.5 01 Aug 1995 | |
*) Added last-minute configurable log experiment, as optional module | |
*) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged | |
properly. (One-line fix to http_protocol.c). | |
*) Work around bogus behavior when reloading from Netscape. | |
It's Netscape's bug --- for some reason they expect a request with | |
If-modified-since: to not function as a conditional GET if it also | |
comes with Pragma: no-cache, which is way out of line with the HTTP | |
spec (according to Roy Fielding, the redactor). | |
*) Added parameter to set maximum number of server processes. | |
*) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg, | |
Jim Jagielski] | |
*) IdentityCheck bugfix [Chuck Murcko]. | |
*) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut] | |
*) More sample config file corrections; add extension to AddType for | |
*.asis, move AddType generic description to its proper place, and | |
fix miscellaneous typos. [ Alexei Kosut ] | |
*) Deleted the *other* reference to the regents from the Berkeley | |
legal disclaimer (everyplace). | |
*) Nuked Shambhala name from src/README; had already cleaned it out | |
of everywhere else. | |
Changes with Apache 0.8.4 | |
*) Changes to server-pool management parms --- renamed current | |
StartServers to MinSpareServers, created separate StartServers | |
parameter which means what it says, and renamed MaxServers to | |
MaxSpareServers (though the old name still works, for NCSA 1.4 | |
back-compatibility). The old names were generally regarded as | |
too confusing. Also altered "docs" in sample config files. | |
*) More improvements to default config files --- | |
sample directives (commented out) for XBitHack, BindAddress, | |
CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage | |
defaults, AddTypes for send-as-is and imagemap magic types, and | |
improvements to samples for DirectoryIndex [Alexei Kosut] | |
*) Yet more improvements to default config files --- changes to | |
Alexei's sample AddLanguage directives, and sample LanguagePriority | |
[ Florent Guillaume ] | |
*) Set config file locations properly if not set in httpd.conf | |
[ David Robinson ] | |
*) Don't escape URIs in internal redirects multiple times; don't | |
do that when translating PATH_INFO to PATH_TRANSLATED either. | |
[ David Robinson ] | |
*) Corrected spelling of "Required" in 401 error reports [Andrew Wilson] | |
Changes with Apache 0.8.3 | |
*) Edited distribution README to *briefly* summarize installation | |
procedures, and give a pointer to the INSTALL file in the src/ | |
directory. | |
*) Upgraded imagemap script in cgi-bin to 1.8 version from more | |
recent NCSA distributions. | |
*) Bug fix to previous bug fix --- if .htaccess file and <Directory> | |
exist for the same directory, use both and don't segfault. [Reported | |
by David Robinson] | |
*) Proper makefile dependencies [David Robinson] | |
*) Note (re)starts in error log --- reported by Rob Hartill. | |
*) Only call no2slash() after get_path_info() has been done, to | |
preserve multiple slashes in the PATH_INFO [NCSA compatibility, | |
reported by Andrew Wilson, though this one is probably a real bug] | |
*) Fixed mod_imap.c --- relative paths with base_uri referer don't | |
dump core when Referer is not supplied. [Randy Terbush] | |
*) Lightly edited sample config files to refer people to our documentation | |
instead of NCSA's, and to list Rob McCool as *original* author (also | |
deleted his old, and no doubt non-functional email address). Would be | |
nice to have examples of new features... | |
Changes with Apache 0.8.2 19 Jul 1995 | |
*) Added AddLanuage code [Florent Guillaume] | |
*) Don't say "access forbidden" when a CGI script is not found. [Mark Cox] | |
*) All sorts of problems when MultiViews finds a directory. It would | |
be nice if mod_dir.c was robust enough to handle that, but for now, | |
just punt. [reported by Brian Behlendorf] | |
*) Wait for all children on restart, to make sure that the old socket | |
is gone and we can reopen it. [reported by Randy Terbush] | |
*) Imagemap module is enabled in default Configuration | |
*) RefererLog and UserAgentLog modules properly default the logfile | |
[Randy Terbush] | |
*) Mark Cox's mod_cookies added to the distribution as an optional | |
module (commented out in the default Configuration, and noted as | |
an experiment, along with mod_dld). [Mark Cox] | |
*) Compiles on ULTRIX (a continuing battle...). [Robert Thau] | |
*) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush] | |
*) Changed "Shambhala" to "Apache" in API docs. [Robert Thau] | |
*) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD | |
license] | |
Changes with Apache 0.8.1 | |
*) New imagemap module [Randy Terbush] | |
*) Replacement referer log module with NCSA-compatible RefererIgnore | |
[Matthew Gray again] | |
*) Don't mung directory listings with very long filenames. | |
[Florent Guillaume] | |
Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995 | |
*) New config script. See INSTALL for info. [Robert Thau] | |
*) Scoreboard mechanism for regulating the number of extant server | |
processes. MaxServers and StartServers defaults are the same as | |
for NCSA, but the meanings are slightly different. (Actually, | |
I should probably lower the MaxServers default to 10). | |
Before asking for a new connection, each server process checks | |
the number of other servers which are also waiting for a | |
connection. If there are more than MaxServers, it quietly dies | |
off. Conversely, every second, the root, or caretaker, process | |
looks to see how many servers are waiting for a new connection; | |
if there are fewer than StartServers, it starts a new one. This | |
does not depend on the number of server processes already extant. | |
The accounting is arranged through a "scoreboard" file, named | |
/tmp/htstatus.*, on which each process has an independent file | |
descriptor (they need to seek without interference). | |
The end effect is that MaxServers is the maximum number of | |
servers on an *inactive* server machine, but more will be forked | |
off to handle unusually heavy loads (or unusually slow clients); | |
these will die off when they are no longer needed --- without | |
reverting to the overhead of full forking operation. There is a | |
hard maximum of 150 server processes compiled in, largely to | |
avoid forking out of control and dragging the machine down. | |
(This is arguably too high). | |
In my server endurance tests, this mechanism did not appear to | |
impose any significant overhead, even after I forced it to put the | |
scoreboard file on a normal filesystem (which might have more | |
overhead than tmpfs). [Robert Thau] | |
*) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts. | |
[Cliff Skolnick] | |
*) Read .htaccess files even in directory with <Directory> section. | |
(Former incompatibility noted on mailing list, now fixed). [Robert | |
Thau] | |
*) "HEAD /" gives the client a "Bad Request" error message, rather | |
than trying to send no body *and* no headers. [Cliff Skolnick]. | |
*) Don't produce double error reports for some very obscure cases | |
mainly involving auth configuration (the "all modules decline to | |
handle" case which is a sure sign of a server bug in most cases, | |
but also happens when authentication is badly misconfigured). | |
[Robert Thau] | |
*) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what | |
it's *for*, and this sort of thing really shouldn't be cluttering | |
up the Makefile). [Robert Thau] | |
*) Incidental code cleanups in http_main.c --- stop dragging | |
sa_client around; just declare it where used. [Robert Thau] | |
*) Another acc-related fix. (It doesn't like const char | |
in some places...). [Mark Cox] | |
Changes with Shambhala 0.6.1 13 Jul 1995 | |
*) Fixed auth_name-related typos in http_core.c [Brian Behlendorf] | |
Also, fixed auth typo in http_protocol.c unmasked by this fix. | |
*) Compiles clean with acc on SunOS [Paul Sutton] | |
*) Reordered modules in modules.c so that Redirect takes priority | |
over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] --- | |
believe it or not, he has an actual site with a ScriptAlias and | |
a Redirect declared for the *exact same directory*. Even *my* | |
compatibility fetish wouldn't motivate me to fix this if the fix | |
required any effort, but it doesn't, so what the hey. | |
*) Fixed to properly default several server_rec fields for virtual | |
servers from the corresponding fields in the main server_rec. | |
[Cliff Skolnick --- 'port' was a particular irritant]. | |
*) No longer kills off nph- child processes before they are | |
finished sending output. [Matthew Gray] | |
Changes with Shambhala 0.6.0 10 Jul 1995 | |
*) Two styles of timeout --- hard and soft. soft_timeout()s just put | |
the connection to the client in an "aborted" state, but otherwise | |
allow whatever handlers are running to clean up. hard_timeout()s | |
abort the request in progress completely; anything not tied to some | |
resource pool cleanup will leak. They're still around because I | |
haven't yet come up with a more elegant way of handling | |
timeouts when talking to something that isn't the client. The | |
default_handler and the dir_handler now use soft timeouts, largely | |
so I can test the feature. [Robert Thau] | |
*) TransferLog "| my_postprocessor ..." seems to be there. Note that | |
the case of log handlers dying prematurely is probably handled VERY | |
gracelessly at this point, and if the logger stops reading input, | |
the server will hang. (It is known to correctly restart the | |
logging process on server restart; this is (should be!) going through | |
the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI | |
script). [Robert Thau] | |
*) asis files supported (new module). [Robert Thau] | |
*) IdentityCheck code is compiled in, but has not been tested. (I | |
don't know anyone who runs identd). [Robert Thau] | |
*) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO | |
came in with the request, for NCSA bug-compatibility. [Robert Thau] | |
*) Don't leak the DIR * on HEAD request for a directory. [Robert Thau] | |
*) Deleted the block_alarms() stuff from dbm_auth; no longer necessary, | |
as timeouts are not in scope. [Robert Thau] | |
*) quoted-string args in config files now handled correctly (doesn't drop | |
the last character). [Robert Thau; reported by Randy Terbush] | |
*) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX. | |
How the hell did it ever work? [Robert Thau; reported by Rob Hartill] | |
*) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time | |
default default type); the former default default behavior when all | |
type-checkers defaulted had been a core dump. [Paul Sutton] | |
*) Copy filenames out of the struct dirent when indexing | |
directories. (On Linux, readdir() returns a pointer to the same | |
memory area every time). Fix is in mod_dir.c. [Paul Sutton] | |
Changes with Shambhala 0.5.3 [not released] | |
*) Default response handler notes "file not found" in the error log, | |
if the file was not found. [Cliff Skolnick]. | |
*) Another Cliff bug --- "GET /~user" now properly redirects (the userdir | |
code no longer sets up bogus PATH_INFO which fakes out the directory | |
handler). [Cliff Skolnick] | |
Changes with Shambhala 0.5.2 06 Jul 1995 | |
*) Changes to http_main.c --- root server no longer plays silly | |
games with SIGCHLD, and so now detects and replaces dying | |
children. Child processes just die on SIGTERM, without taking | |
the whole process group with them. Potential problem --- if any | |
child process refuses to die, we hang in restart. | |
MaxRequestsPerChild may still not work, but it certainly works | |
better than it did before this! [Robert Thau] | |
*) mod_dir.c bug fixes: ReadmeName and HeaderName | |
work (or work better, at least); over-long description lines | |
properly terminated. [Mark Cox] | |
*) http_request.c now calls unescape_url() more places where it | |
should [Paul Sutton]. | |
*) More directory handling bugs (reported by Cox) | |
Parent Directory link is now set correctly. [Robert Thau] | |
Changes with Shambhala 0.5.1 04 Jul 1995 | |
*) Generalized cleanup interface in alloc.c --- any function can be | |
registered with alloc.c as a cleanup for a resource pool; | |
tracking of files and file descriptors has been reimplemented in | |
terms of this interface, so I can give it some sort of a test. | |
[Robert Thau] | |
*) More changes in alloc.c --- new cleanup_for_exec() function, | |
which tracks down and closes all file descriptors which have been | |
registered with the alloc.c machinery before the server exec()s a | |
child process for CGI or <!--#exec-->. CGI children now get | |
started with exactly three file descriptors open. Hopefully, | |
this cures the problem Rob H. was having with overly persistent | |
CGI connections. [Robert Thau] | |
*) Mutual exclusion around the accept() in child_main() --- this is | |
required on at least SGI, Solaris and Linux, and is #ifdef'ed in | |
by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT). | |
This uses fcntl(F_SETLK,...) on the error log descriptor because | |
flock() on that descriptor won't work on systems which have BSD | |
flock() semantics, including (I think) Linux 1.3 and Solaris. | |
This does work on SunOS (when the server is idle, only one | |
process in the pool is waiting on accept()); it *ought* to work | |
on the other systems. [Robert Thau] | |
*) FreeBSD and BSDI portability tweaks [Chuck Murcko] | |
*) sizeof(*sa_client) bugfix from [Rob Hartill] | |
*) pstrdup(..., NULL) returns NULL, [Randy Terbush] | |
*) block_alarms() to avoid leaking the DBM* in dbm auth (this should | |
be unnecessary if I go to the revised timeout-handling scheme). | |
[Robert Thau] | |
*) For NCSA bug-compatibility, set QUERY_STRING env var (to a null | |
string) even if none came in with the request. [Robert Thau] | |
*) CHANGES file added to distribution ;-). | |
Changes with Shambhala 0.4.5 | |
*) mod_dld --- early dynamic loading support [rst] | |
*) Add wildcard content handlers for XBITHACK; default_hander now | |
invoked with that mechanism (as a handler hanging off mod_core) [rst] | |
*) XBITHACK supported as a wildcard content-handler, and | |
configurable at run-time (not just at compile time, as in the | |
"patchy server" releases) [rst] | |
Changes with Shambhala 0.4.4 30 Jun 1995 | |
*) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox] | |
*) Handle Addtype x/y .z [rst, reported by Cox] | |
Changes with Shambhala 0.4.3 | |
*) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not | |
synonymous [rst, terbush] | |
Changes with Shambhala 0.4.1 28 Jun 1995 | |
*) First-cut virtual host implementation; some refit in the config | |
reading code, and log management, was necessary to support this [rst] | |
*) Sub-pool machinery, originally added to avoid excessive storage | |
allocation on listings of large directories (which turned out to | |
be the problem that the 0.3 storage accounting was added to | |
find). Subrequests and mod_dir changed to use subpools. [rst] | |
*) More memory debugging --- free list consistency checks. [rst] | |
*) Added err_headers to request_rec, with support elsewhere [rst] | |
*) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush] | |
Changes with Shambhala 0.3 19 Jun 1995 | |
*) Switch ONE_PROCESS to a runtime command-line option (-X) | |
*) Don't compile in mod_ai_backcompat by default | |
*) Switch name of server from Apache to Shambhala in Makefile | |
*) Add some accounting routines to track memory usage in the pools, | |
for debugging | |
Changes with Shambhala 0.2 | |
*) Set DOCUMENT_ROOT CGI variable | |
*) Add single-process debugging, as a compile-time option (ONE_PROCESS) | |
*) Add critical section protection to handling of cleanup structures | |
in alloc.c [rst] | |
*) Significant code reorg within the server core to group related | |
functions together [rst] | |
*) Correctly handle clients that hang up before sending any request | |
[rst] | |
*) Replace dying child processes. [rst] | |
Changes with Shambhala 0.1 12 Jun 1995 | |
Major rewrite of the pre-existing "patchy server" codebase, by | |
Robert Thau (rst). Significant portions of the server code, such | |
as configuration-file handling and HTTP authentication support, | |
were ripped out and rewritten from scratch. Code that was not | |
completely rewritten was significantly altered. | |
Major changes with this release include: | |
*) Introduction of the module API; in request handling, the central | |
machinery just dispatches to various modules, which actually do | |
most of the work. Configuration handling is similar --- modules | |
declare their own commands, and the central machinery just | |
dispatches to them. | |
API features from shambhala/0.1 were substantially unchanged in | |
Apache 1.0 and 1.1. (1.0 API features not yet present in this | |
release, such as wildcard handlers and subpools, were added in | |
subsequent Shambhala releases, and were also generally rst's | |
work). | |
*) This release included the following modules: | |
mod_access (access control --- allow and deny directives), | |
mod_alias (Alias and Redirect commands), | |
mod_auth (straight HTTP authentication, based on flat-files) | |
mod_auth_dbm (same, with dbm files) | |
mod_cgi (CGI scripts and, in this release, ScriptAlias) | |
mod_common_log (CLF access logs; later renamed mod_log_common) | |
mod_dir (directory indexing) | |
mod_include (server-side includes) | |
mod_mime (AddType directives) | |
mod_negotiation (content negotiation) | |
mod_userdir (support for users' public_html directories) | |
It also included a mod_ai_backcompat, which was a private hack | |
for back-compatibility with rst's own AI-lab servers. | |
All of these modules were substantially complete, and functional | |
or nearly so (a few, which implemented features not in use at | |
Thau's site, required patches of a few lines). | |
*) sub-request machinery, to allow modules to determine how other | |
modules would assign MIME types to a given file, or optionally | |
serve its content (this is heavily used by mod_dir, mod_include | |
and mod_negotiation). | |
*) Resource pool system for keeping track of memory allocated and | |
files opened in service of a particular request. Much of the | |
code in the modules (when they weren't rewrites) was adjusted to | |
replace a pervasive convention of using fixed-size buffers on | |
the stack with an equally pervasive convention of using memory | |
allocated with palloc(). | |
*) Reorganization of data structures associated with a given | |
request to eliminate use of global variables and the troublesome | |
unmunge_name function (used in NCSA and early Apache releases to | |
attempt to determine the URI which mapped to a given filename | |
--- a difficult proposition, given that it is easy to produce | |
setups in which multiple URIs map to the same file). | |
*) Source files renamed and rearranged | |
*) Very simple pre-forking behavior --- parent process forked off a | |
fixed number of children, and then just waited for SIGHUP. | |
*) Other more minor changes too numerous to list. | |
This release included modified versions of a lot of code from the | |
Apache 0.6.4 public release, plus an early pre-forking patch | |
codeveloped by Robert Thau and Rob Hartill. | |
Changes with Apache 0.7.3 20 Jun 1995 | |
*) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that | |
were incorporated by Rob Hartill on the main branch while Robert Thau | |
worked on the Shambhala rewrite above. Most were merged into the | |
Shambala architecture after Apache 0.8.0. | |
