From d773144417b1a87b4529144ab0530ecfea103754 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 30 Aug 2014 11:47:19 +0200 Subject: [PATCH] pack-write: simplify index_pack_lockfile using skip_prefix() and xstrfmt() Get rid of magic string length constants by using skip_prefix() instead of memcmp() and use xstrfmt() for building a string instead of a PATH_MAX-sized buffer, snprintf() and xstrdup().
