Introduce a new whitespace error class, blank-at-eof, to make the whitespace error handling more consistent. The patch adds a new "linenr" field to the struct fragment in order to record which line the hunk started in the input file, but this is needed solely for reporting purposes. The detection of this class of whitespace errors cannot be done while parsing a patch like we do for all the other classes of whitespace errors. It instead has to wait until we find where to apply the hunk, but at that point, we do not have an access to the original line number in the input file anymore, hence the new field. Depending on your point of view, this may be a bugfix that makes warn and error in line with fix. Or you could call it a new feature. The line between them is somewhat fuzzy in this case. Strictly speaking, triggering more errors than before is a change in behaviour that is not backward compatible, even though the reason for the change is because the code was not checking for an error that it should have. People who do not want added blank lines at EOF to trigger an error can disable the new error class.

Earlier attempt to introduce only blank-at-eof gave them an escape hatch to keep the old behaviour, but it is a regression until they explicitly specify the new error class. This introduces a blank-at-eol that only catches extra white space at the end of line, and makes the traditional trailing-space a convenient synonym to catch both blank-at-eol and blank-at-eof.

This behavior was originally implemented very early on in 9ff768e, but only for --exclude-from. Later, commit 63d285c accidentally caused us to trigger the behavior for --exclude-per-directory. This patch totally ignores excludes for files found in the index. This means we are reversing the original intent of 9ff768e, while at the same time fixing the accidental behavior of 63d285c. This is a good thing, though, as the way that 9ff768e behaved does not really make sense with the way exclusions are used in modern git.

Pearce" Date: Wed, 14 Oct 2009 07:23:51 -0700 Subject: [PATCH 055/366] sha1_file: Fix infinite loop when pack is corrupted Some types of corruption to a pack may confuse the deflate stream which stores an object. In Andy's reported case a 36 byte region of the pack was overwritten, leading to what appeared to be a valid deflate stream that was trying to produce a result larger than our allocated output buffer could accept. Z_BUF_ERROR is returned from inflate() if either the input buffer needs more input bytes, or the output buffer has run out of space. Previously we only considered the former case, as it meant we needed to move the stream's input buffer to the next window in the pack. We now abort the loop if inflate() returns Z_BUF_ERROR without consuming the entire input buffer it was given, or has filled the entire output buffer but has not yet returned Z_STREAM_END. Either state is a clear indicator that this loop is not working as expected, and should not continue. This problem cannot occur with loose objects as we open the entire loose object as a single buffer and treat Z_BUF_ERROR as an error. Reported-by: Andy Isaacson Signed-off-by: Shawn O.

The strategy is to replace a single new-line with a space, but keep double new-lines so that already-wrapped text with empty lines between paragraphs will be handled properly. However, single new-line characters are only handled this way if the character after it is an alphanumeric character, as per Linus' suggestion.

The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1).

The idea for the hashmap singleton is from David Reiss, initial benchmarking by Jeff King. Note: the implementation allows for arbitrary entries in the notes tree object, ignoring those that do not reference a valid object. This allows you to annotate arbitrary branches, or objects.

The patch also updates the "git notes" documentation and adds selftests for the new functionality.

This subcommand is similar to 'filemodify', except that no mode is supplied (all notes have mode 0644), and the path is set to the hex SHA1 of the given "comittish". This enables fast import of note objects along with their associated commits, since the notes can now be named using the mark references of their corresponding commits.

If there are several notes objects referencing a given commit, only one of those objects are used. - If a notes object for a given commit is present in the "root" notes tree, no subtrees are consulted; the object in the root tree is used directly. - If there are more than one subtree that prefix-matches the given commit, only the subtree with the longest matching prefix is consulted. This means that if the given commit is e.g. "deadbeef", and the notes tree have subtrees "de" and "dead", then the following paths in the notes tree are searched: "deadbeef", "dead/beef". Note that "de/adbeef" is NOT searched. - Fanout directories (subtrees) must references a whole number of bytes from the SHA1 sum they subdivide. E.g. subtrees "dead" and "de" are acceptable; "d" and "dea" are not. - Multiple levels of fanout are allowed. All the above rules apply recursively. E.g. "de/adbeef" is preferred over "de/adbe/ef", etc. This patch changes the in-memory datastructure for holding parsed notes: Instead of holding all note (and subtree) entries in a hash table, a simple 16-tree structure is used instead. The tree structure consists of 16-arrays as internal nodes, and note/subtree entries as leaf nodes. The tree is traversed by indexing subsequent nibbles of the search key until a leaf node is encountered. If a subtree entry is encountered while searching for a note, the subtree is unpacked into the 16-tree structure, and the search continues into that subtree. The new algorithm performs significantly better in the cases where only a fraction of the notes need to be looked up (this is assumed to be the common case for notes lookup). The new code even performs marginally better in the worst case (where _all_ the notes are looked up). In addition to this, comes the massive performance win associated with organizing the notes tree according to some fanout scheme. Even a simple 2/38 fanout scheme is dramatically quicker to traverse (going from tens of seconds to sub-second runtimes). As for memory usage, the new code is marginally better than the old code in the worst case, but in the case of looking up only some notes from a notes tree with proper fanout, the new code uses only a small fraction of the memory needed to hold the entire notes tree. However, there is one casualty of this patch. The old notes lookup code was able to parse notes that were associated with non-SHA1s (e.g. refs). The new code requires the referenced object to be named by a SHA1 sum. Still, this is not considered a major setback, since the notes infrastructure was not originally intended to annotate objects outside the Git object database.

This patch teaches the notes code to _concatenate_ multiple notes that annotate the same commit. Notes are concatenated by creating a new blob object containing the concatenation of the notes in question, and replacing them with the concatenated note in the internal notes tree structure. Getting the concatenation right requires being more proactive in unpacking subtree entries in the internal notes tree structure, so that we don't return a note prematurely (i.e. before having found all other notes that annotate the same object). As such, this patch may incur a small performance penalty.

Because of this, it has inherited some code that makes sense for isync, but not for imap-send. In particular, when storing a message, it does one of: - if the server supports it, note the server-assigned unique identifier (UID) given to each message - otherwise, assigned a random UID and store it in the message header as X-TUID Presumably this is used in isync to be able to synchronize mailstores multiple times without duplication. But for imap-send, the values are useless; we never do anything with them and simply forget them at the end of the program. This patch removes the useless code. Not only is it nice for maintainability to get rid of dead code, but the removed code relied on the existence of /dev/urandom, which made it a portability problem for non-Unix platforms.

Refactor most of them into a struct to make future extensions easier. The ones that stay "plain" arguments were chosen on the grounds that all callers put real arguments there, whereas some callers have 0/NULL for all arguments that were factored into the struct. We declare the struct 'const' to ensure none of the callers are bitten by the changed (no longer call-by-value) semantics.

We use the newly refactored get_reflog_selector(), and give it some extra functionality to extract a shortened ref. The shortening is cached inside the commit_reflogs struct; the only allocation of it happens in read_complete_reflog(), where it is initialised to 0. Also add another helper get_reflog_message() for the message extraction. Note that the --format="%h %gD: %gs" tests may not work in real repositories, as the --pretty formatter doesn't know to leave away the ": " on the last commit in an incomplete (because git-gc removed the old part) reflog. This equivalence is nevertheless the main goal of this patch. Thanks to Jeff King for reviews, the %gd testcase and documentation.

Developers who wanted to make sure that git correctly dealt with packfiles could deliberately trigger their creation and checked them after they were created carefully, but loose objects are the ones that are written by various commands from random codepaths. It made some technical sense to have a mode that checked only loose objects from the debugging point of view for that reason. Even for git developers, there no longer is any reason to type "git fsck" every five minutes these days, worried that some newly created objects might be corrupt due to recent change to git. The reason we did not make "--full" the default is probably we trust our filesystems a bit too much. At least, we trusted filesystems more than we trusted the lower core part of git that was under development. Once a packfile is created and we always use it read-only, there didn't seem to be much point in suspecting that the underlying filesystems or disks may corrupt them in such a way that is not caught by the SHA-1 checksum over the entire packfile and per object checksum. That trust in the filesystems might have been a good tradeoff between fsck performance and reliability on platforms git was initially developed on and for, but it may not be true anymore as we run on many more platforms these days.

Side note. This magic number 20 does not have anything to do with the size of the hash we use, but comes from 1a3b55c (reduce delta head inflated size, 2006-10-18). The loop reads like this: do { in = use_pack(); stream.next_in = in; st = git_inflate(&stream, Z_FINISH); curpos += stream.next_in - in; } while ((st == Z_OK || st == Z_BUF_ERROR) && stream.total_out < sizeof(delta_head)); This git_inflate() can return: - Z_STREAM_END, if use_pack() fed it enough input and the delta itself was smaller than 20 bytes; - Z_OK, when some progress has been made; - Z_BUF_ERROR, if no progress is possible, because we either ran out of input (due to corrupt pack), or we ran out of output before we saw the end of the stream. The fix b3118bd (sha1_file: Fix infinite loop when pack is corrupted, 2009-10-14) attempted was against a corruption that appears to be a valid stream that produces a result larger than the output buffer, but we are not even trying to read the stream to the end in this loop. If avail_out becomes zero, total_out will be the same as sizeof(delta_head) so the loop will terminate without the "fix". There is no fix from b3118bd needed for this loop, in other words. The loop in unpack_compressed_entry() is quite a different story. It feeds a deflated stream (either delta or base) and allows the stream to produce output up to what we expect but no more. do { in = use_pack(); stream.next_in = in; st = git_inflate(&stream, Z_FINISH); curpos += stream.next_in - in; } while (st == Z_OK || st == Z_BUF_ERROR) This _does_ risk falling into an endless interation, as we can exhaust avail_out if the length we expect is smaller than what the stream wants to produce (due to pack corruption). In such a case, avail_out will become zero and inflate() will return Z_BUF_ERROR, while avail_in may (or may not) be zero. But this is not a right fix: do { in = use_pack(); stream.next_in = in; st = git_inflate(&stream, Z_FINISH); + if (st == Z_BUF_ERROR && (stream.avail_in || !stream.avail_out) + break; /* wants more input??? */ curpos += stream.next_in - in; } while (st == Z_OK || st == Z_BUF_ERROR) as Z_BUF_ERROR from inflate() may be telling us that avail_in has also run out before reading the end of stream marker. In such a case, both avail_in and avail_out would be zero, and the loop should iterate to allow the end of stream marker to be seen by inflate from the input stream. The right fix for this loop is likely to be to increment the initial avail_out by one (we allocate one extra byte to terminate it with NUL anyway, so there is no risk to overrun the buffer), and break out if we see that avail_out has become zero, in order to detect that the stream wants to produce more than what we expect. After the loop, we have a check that exactly tests this condition: if ((st != Z_STREAM_END) || stream.total_out != size) { free(buffer); return NULL; } So here is a patch (without my previous botched attempts) to fix this issue. The first hunk reverts the corresponding hunk from b3118bd, and the second hunk is the same fix proposed earlier.

This does achieve the quoting goal, but modern 'man' implementations turn the apostrophe into a unicode "proper" apostrophe (given the right circumstances), breaking code examples in many of our manpages. Quote them as \(aq instead, which is an "apostrophe quote" as per the groff_char manpage. Unfortunately, as Anders Kaseorg kindly pointed out, this is not portable beyond groff, so we add an extra Makefile variable GNU_ROFF which you need to enable to get the new quoting.

Previously, we would load the config on demand only when we needed to look at push.default. Which meant that "git push" would load it, but "git push remote" would not, leading to differing behavior.

E.g. $ git describe --dirty v1.6.5-15-gc274db7 $ echo >> Makefile $ git describe --dirty v1.6.5-15-gc274db7-dirty The --dirty option can also be used to specify what is appended, instead of the default string "-dirty". $ git describe --dirty=.mod v1.6.5-15-gc274db7.mod Many build scripts use `git describe` to produce a version number based on the description of HEAD (on which the work tree is based) + saying that if the build contains uncommitted changes. This patch helps the writing of such scripts since `git describe --dirty` does directly the intended thing. Three possiblities were considered while discussing this new feature: 1. Describe the work tree by default and describe HEAD only if "HEAD" is explicitly specified Pro: does the right thing by default (both for users and for scripts) Pro: other git commands that works on the work tree by default Con: breaks existing scripts used by the Linux kernel and other projects 2. Use --worktree instead of --dirty Pro: does what it says: "git describe --worktree" describes the work tree Con: other commands do not require a --worktree option when working on the work tree (it often is the default mode for them) Con: unusable with an optional value: "git describe --worktree=.mod" is quite unintuitive. 3. Use --dirty as in this patch Pro: makes sense to specify an optional value (what the dirty mark is) Pro: does not have any of the big cons of previous alternatives * does not break scripts * is not inconsistent with other git commands This patch takes the third approach.

However, for files with no content, the diff shows just the 'deleted file mode ...' line. This patch cause "add -p" (and related commands) to recognize that line and explicitly ask about deleting the file. We only add the "stage this deletion" hunk for empty files, since other files will already ask about the big content deletion hunk. We could also change those files to simply display "stage this deletion", but showing the actual deleted content is probably what an interactive user wants.

Sometimes I want to do bisection based on all commits (no pathname limiting), but then visualize the current bisection tree with just a few pathnames because I _suspect_ those pathnames are involved in the problem but am not totally sure about them. And at other times, I want to use other revision parsing logic, none of which is available with "git bisect visualize". So this adds "--bisect" as a revision parsing argument, and as a result it just works with all the normal logging tools. So now I can just do gitk --bisect --simplify-by-decoration filename-here etc. Signed-off-by: Linus Torvalds Signed-off-by: Junio C Hamano --- builtin-rev-list.c | 2 ++ builtin-rev-parse.c | 11 +++++++++++ revision.c | 19 ++++++++++++++++++- revision.h | 1 + 4 files changed, 32 insertions(+), 1 deletion(-) diff --git a/builtin-rev-list.c b/builtin-rev-list.c index 4ba1c12e0..32bf033b5 100644 --- a/builtin-rev-list.c +++ b/builtin-rev-list.c @@ -319,6 +319,8 @@ int cmd_rev_list(int argc, const char **argv, const char *prefix) memset(&info, 0, sizeof(info)); info.revs = &revs; + if (revs.bisect) + bisect_list = 1; quiet = DIFF_OPT_TST(&revs.diffopt, QUIET); for (i = 1 ; i < argc; i++) { diff --git a/builtin-rev-parse.c b/builtin-rev-parse.c index 45bead654..9526aafc6 100644 --- a/builtin-rev-parse.c +++ b/builtin-rev-parse.c @@ -180,6 +180,12 @@ static int show_reference(const char *refname, const unsigned char *sha1, int fl return 0; } +static int anti_reference(const char *refname, const unsigned char *sha1, int flag, void *cb_data) +{ + show_rev(REVERSED, sha1, refname); + return 0; +} + static void show_datestring(const char *flag, const char *datestr) { static char buffer[100]; @@ -548,6 +554,11 @@ int cmd_rev_parse(int argc, const char **argv, const char *prefix) for_each_ref(show_reference, NULL); continue; } + if (!strcmp(arg, "--bisect")) { + for_each_ref_in("refs/bisect/bad", show_reference, NULL); + for_each_ref_in("refs/bisect/good", anti_reference, NULL); + continue; + } if (!strcmp(arg, "--branches")) { for_each_branch_ref(show_reference, NULL); continue; diff --git a/revision.c b/revision.c index 9fc4e8d38..a36c0d9bc 100644 --- a/revision.c +++ b/revision.c @@ -994,7 +994,8 @@ static int handle_revision_opt(struct rev_info *revs, int argc, const char **arg if (!strcmp(arg, "--all") || !strcmp(arg, "--branches") || !strcmp(arg, "--tags") || !strcmp(arg, "--remotes") || !strcmp(arg, "--reflog") || !strcmp(arg, "--not") || - !strcmp(arg, "--no-walk") || !strcmp(arg, "--do-walk")) + !strcmp(arg, "--no-walk") || !strcmp(arg, "--do-walk") || + !strcmp(arg, "--bisect")) { unkv[(*unkc)++] = arg; return 1; @@ -1218,6 +1219,16 @@ void parse_revision_opt(struct rev_info *revs, struct parse_opt_ctx_t *ctx, ctx->argc -= n; } +static int for_each_bad_bisect_ref(each_ref_fn fn, void *cb_data) +{ + return for_each_ref_in("refs/bisect/bad", fn, cb_data); +} + +static int for_each_good_bisect_ref(each_ref_fn fn, void *cb_data) +{ + return for_each_ref_in("refs/bisect/good", fn, cb_data); +} + /* * Parse revision information, filling in the "rev_info" structure, * and removing the used arguments from the argument list. @@ -1259,6 +1270,12 @@ int setup_revisions(int argc, const char **argv, struct rev_info *revs, const ch handle_refs(revs, flags, for_each_branch_ref); continue; } + if (!strcmp(arg, "--bisect")) { + handle_refs(revs, flags, for_each_bad_bisect_ref); + handle_refs(revs, flags ^ UNINTERESTING, for_each_good_bisect_ref); + revs->bisect = 1; + continue; + } if (!strcmp(arg, "--tags")) { handle_refs(revs, flags, for_each_tag_ref); continue; diff --git a/revision.h b/revision.h index b6421a643..921656aaa 100644 --- a/revision.h +++ b/revision.h @@ -63,6 +63,7 @@ struct rev_info { reverse:1, reverse_output_stage:1, cherry_pick:1, + bisect:1, first_parent_only:1; /* Diff flags */ From 4d23660e79dbbb7e2ae37cb7193166d085a78502 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Wed, 28 Oct 2009 23:10:06 +0100 Subject: [PATCH 150/366] describe: when failing, tell the user about options that work Users seem to call git-describe without reading the manpage, and then wonder why it doesn't work with unannotated tags by default.

By changing the enabled capabilities to be formatted in a strbuf it is easier to add a new capability to the set of supported capabilities. By formatting the want portion of the request into a strbuf and writing it as a whole block we can later decide to hold onto the req_buf (instead of releasing it) to recycle in stateless communications.

Pearce" Date: Fri, 30 Oct 2009 17:47:25 -0700 Subject: [PATCH 172/366] Add multi_ack_detailed capability to fetch-pack/upload-pack When multi_ack_detailed is enabled the ACK continue messages returned by the remote upload-pack are broken out to describe the different states within the peer. This permits the client to better understand the server's in-memory state. The fetch-pack/upload-pack protocol now looks like: NAK --------------------------------- Always sent in response to "done" if there was no common base selected from the "have" lines (or no have lines were sent). * no multi_ack or multi_ack_detailed: Sent when the client has sent a pkt-line flush ("0000") and the server has not yet found a common base object. * either multi_ack or multi_ack_detailed: Always sent in response to a pkt-line flush. ACK %s ----------------------------------- * no multi_ack or multi_ack_detailed: Sent in response to "have" when the object exists on the remote side and is therefore an object in common between the peers. The argument is the SHA-1 of the common object. * either multi_ack or multi_ack_detailed: Sent in response to "done" if there are common objects. The argument is the last SHA-1 determined to be common. ACK %s continue ----------------------------------- * multi_ack only: Sent in response to "have". The remote side wants the client to consider this object as common, and immediately stop transmitting additional "have" lines for objects that are reachable from it. The reason the client should stop is not given, but is one of the two cases below available under multi_ack_detailed. ACK %s common ----------------------------------- * multi_ack_detailed only: Sent in response to "have". Both sides have this object. Like with "ACK %s continue" above the client should stop sending have lines reachable for objects from the argument. ACK %s ready ----------------------------------- * multi_ack_detailed only: Sent in response to "have". The client should stop transmitting objects which are reachable from the argument, and send "done" soon to get the objects. If the remote side has the specified object, it should first send an "ACK %s common" message prior to sending "ACK %s ready". Clients may still submit additional "have" lines if there are more side branches for the client to explore that might be added to the common set and reduce the number of objects to transfer.

Pearce" Date: Fri, 30 Oct 2009 17:47:30 -0700 Subject: [PATCH 177/366] Move WebDAV HTTP push under remote-curl The remote helper interface now supports the push capability, which can be used to ask the implementation to push one or more specs to the remote repository. For remote-curl we implement this by calling the existing WebDAV based git-http-push executable. Internally the helper interface uses the push_refs transport hook so that the complexity of the refspec parsing and matching can be reused between remote implementations. When possible however the helper protocol uses source ref name rather than the source SHA-1, thereby allowing the helper to access this name if it is useful. >From Clemens Buchacher : update http tests according to remote-curl capabilities o Pushing packed refs is now fixed. o The transport helper fails if refs are already up-to-date. Add a test for that. o The transport helper will notice if refs are already up-to-date. We therefore need to update server info in the unpacked-refs test. o The transport helper will purge deleted branches automatically. o Use a variable ($ORIG_HEAD) instead of full SHA-1 name.

This function knows two sets of helpers (one for line-oriented diff, another for word diff), and each set has various functions to be called at certain places (e.g. hunk header, context, ...). The function's role is to inspect the incoming line, and dispatch appropriate helpers to produce either line- or word- oriented diff output." * introduce fn_out_consume_word_diff() that is "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to prepare word oriented diff using that line." without touching fn_out_consume() at all. * Do neither of the above, and keep fn_out_consume() to "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to output line oriented diff using that line." but sprinkle a handful of 'are we in word-diff mode? if so do this totally different thing' at random places. This patch is to at least abstract the details of "this totally different thing" out from the main codepath, in order to improve readability. We can later refactor it by introducing fn_out_consume_word_diff(), taking the second route above, but that is a separate topic.

This involved a bunch of ill-tested special cases. Instead, simply get the struct remote for the URL with remote_get(), which works fine outside a git repository, and can also take global options into account. This fixes a tiny and obscure bug where "git ls-remote" without a repo didn't support global url.*.insteadOf, even though "git clone" and "git ls-remote" in any repo did. Also, enforce that all callers provide a struct remote to transport_get().

Pearce" Date: Fri, 30 Oct 2009 17:47:33 -0700 Subject: [PATCH 190/366] Add stateless RPC options to upload-pack, receive-pack When --stateless-rpc is passed as a command line parameter to upload-pack or receive-pack the programs now assume they may perform only a single read-write cycle with stdin and stdout. This fits with the HTTP POST request processing model where a program may read the request, write a response, and must exit. When --advertise-refs is passed as a command line parameter only the initial ref advertisement is output, and the program exits immediately.

Pearce" Date: Fri, 30 Oct 2009 17:47:34 -0700 Subject: [PATCH 191/366] Smart fetch and push over HTTP: server side Requests for $GIT_URL/git-receive-pack and $GIT_URL/git-upload-pack are forwarded to the corresponding backend process by directly executing it and leaving stdin and stdout connected to the invoking web server. Prior to starting the backend process the HTTP response headers are sent, thereby freeing the backend from needing to know about the HTTP protocol. Requests that are encoded with Content-Encoding: gzip are automatically inflated before being streamed into the backend. This is primarily useful for the git-upload-pack backend, which receives highly repetitive text data from clients that easily compresses to 50% of its original size. Signed-off-by: Shawn O.

Pearce" Date: Fri, 30 Oct 2009 17:47:41 -0700 Subject: [PATCH 198/366] Smart push over HTTP: client side The git-remote-curl backend detects if the remote server supports the git-receive-pack service, and if so, runs git-send-pack in a pipe to dump the command and pack data as a single POST request. The advertisements from the server that were obtained during the discovery are passed into git-send-pack before the POST request starts. This permits git-send-pack to operate largely unmodified. For smaller packs (those under 1 MiB) a HTTP/1.0 POST with a Content-Length is used, permitting interaction with any server. The 1 MiB limit is arbitrary, but is sufficent to fit most deltas created by human authors against text sources with the occasional small binary file (e.g. few KiB icon image). The configuration option http.postBuffer can be used to increase (or shink) this buffer if the default is not sufficient. For larger packs which cannot be spooled entirely into the helper's memory space (due to http.postBuffer being too small), the POST request requires HTTP/1.1 and sets "Transfer-Encoding: chunked". This permits the client to upload an unknown amount of data in one HTTP transaction without needing to pregenerate the entire pack file locally. Signed-off-by: Shawn O.

Pearce" Date: Fri, 30 Oct 2009 17:47:42 -0700 Subject: [PATCH 199/366] Smart fetch over HTTP: client side The git-remote-curl backend detects if the remote server supports the git-upload-pack service, and if so, runs git-fetch-pack locally in a pipe to generate the want/have commands. The advertisements from the server that were obtained during the discovery are passed into git-fetch-pack before the POST request starts, permitting server capability discovery and enablement. Common objects that are discovered are appended onto the request as have lines and are sent again on the next request. This allows the remote side to reinitialize its in-memory list of common objects during the next request. Because all requests are relatively short, below git-remote-curl's 1 MiB buffer limit, requests will use the standard Content-Length header and be valid HTTP/1.0 POST requests. This makes the fetch client more tolerant of proxy servers which don't support HTTP/1.1 or the chunked transfer encoding. Signed-off-by: Shawn O.

Pearce" Date: Fri, 30 Oct 2009 17:47:47 -0700 Subject: [PATCH 204/366] test smart http fetch and push The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.

Finally, we remove the TODO notes, because fetch, push, and clone have their own tests since t1200 was introduced and we're not going to add them here 4 years later.

This meant that "format-patch -p" would suppress the stat and show just the patch. Commit 68daa64 changed this to keep the stat format when we had an "implicit" patch format, like "-U5". As a side effect, this meant that an explicit patch format was now ignored (because cmd_format_patch didn't know the reason that the format was set way down in diff_opt_parse). This patch unbreaks what 68daa64 did (while still preserving what 68daa64 was trying to do), reinstating "-p" to suppress the default behavior. We do this by parsing "-p" ourselves in format-patch, and noting whether it was used explicitly.

Currently this test script contains only tests of snapshot naming (proposed name of snapshot file) and snapshot prefix (prefix of files in the archive / snapshot). It defines and uses 'tar' snapshot format, without compression, for easy checking of snapshot prefix. Testing is done using check_snapshot function. Gitweb uses the following format for snapshot filenames: - where is project name with '.git' or '/.git' suffix stripped, unless '.git' is the whole project name. For snapshot prefix it uses simply: / Disadvantages of current snapshot rules: * There exists convention that . archive unpacks to / directory (/ is prefix of archive). Gitweb does not respect it * Snapshot links generated by gitweb use full SHA-1 id as a value of 'h' / $hash parameter. With current rules it leads to long file names like e.g. repo-1005c80cc11c531d327b12195027cbbb4ff9e3cb.tgz * For handcrafted URLs, where 'h' / $hash parameter is a symbolic 'volatile' revision name such as "HEAD" or "next" snapshot name doesn't tell us what exact version it was created from * Proposed filename in Content-Disposition header should not contain any directory path information, which means that it should not contain '/' (see RFC2183)... which means that snapshot naming is broken for $hash being e.g. hirearchical branch name such as 'xx/test' This would be improved in next commit.

Pearce" Date: Mon, 9 Nov 2009 11:26:43 -0800 Subject: [PATCH 224/366] http-backend: Protect GIT_PROJECT_ROOT from /../ requests Eons ago HPA taught git-daemon how to protect itself from /../ attacks, which Junio brought back into service in d79374c7b58d ("daemon.c and path.enter_repo(): revamp path validation"). I did not carry this into git-http-backend as originally we relied only upon PATH_TRANSLATED, and assumed the HTTP server had done its access control checks to validate the resolved path was within a directory permitting access from the remote client. This would usually be sufficient to protect a server from requests for its /etc/passwd file by http://host/smart/../etc/passwd sorts of URLs. However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an additional method of configuring the CGI. When this environment variable is used the web server does not generate the final access path and therefore may blindly pass through "/../etc/passwd" in PATH_INFO under the assumption that "/../" might have special meaning to the invoked CGI. Instead of permitting these sorts of malformed path requests, we now reject them back at the client, with an error message for the server log. This matches git-daemon behavior.

The application has explicitly asked the server for a single content type, but libcurl has mistakenly also told the server the client application will accept */*, which is any content type. Based on the libcurl change log, this "Accept: */*" header bug may have been fixed in version 7.18.1 released March 30, 2008: http://curl.haxx.se/changes.html#7_18_1 Rather than require users to upgrade libcurl we change the test vector to trim this line out of the 2nd request.

"show-ref -h" currently is short for "show-ref --head", which shows all the refs/* and HEAD, as opposed to "show-ref" that shows all the refs/* and not HEAD. Does anybody use "show-ref -h"? It was in Linus's original, most likely only because "it might be handy", not because "the command should not show the HEAD by default for such and such reasons". So I think it is okay if "show-ref -h" (but not "show-ref --head") gives help and exits. If a current script uses "git show-ref -h" without any other arguments, it would have to be adapted by changing "-h" to "--head".

However, -p is also needed in combination with certain options (e.g. --stat or --numstat) in order to produce any patch at all. The documentation does not mention this. Since the purpose of format-patch is to produce a patch that can be emailed, it does not make sense that certain combination of options will suppress the generation of the patch itself. Therefore: * Update 'git format-patch' to always generate a patch. * Since the --name-only, --name-status, and --check suppresses the generation of the patch, disallow those options, and remove the description of them in the documentation. * Remove the reference to -p in the description of -U. * Remove the descriptions of the options that are synonyms for -p plus another option (--patch-with-raw and --patch-with-stat). * While at it, slightly tweak the description of -p itself to say that it generates "plain patches", so that you can think of -p as "plain patch" as an mnemonic aid.
