From 200ebe362cda2a520219f998d4b2c44767992bdb Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sat, 26 Jan 2013 04:42:45 -0500 Subject: [PATCH] commit: drop useless xstrdup of commit message When git-commit is asked to reuse a commit message via "-c", we call read_commit_message, which looks up the commit and hands back either the re-encoded result, or a copy of the original. We make a copy in the latter case so that the ownership semantics of the return value are clear (in either case, it can be freed). However, since we return a "const char *", and since the resulting buffer's lifetime is the same as that of the whole program, we never bother to free it at all. Let's just drop the copy. That saves us a copy in the common case. While it does mean we leak in the re-encode case, it doesn't matter, since we are relying on program exit to free the memory anyway.
