From 095c741edd1d9604b6c285000a836721fd69f051 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Wed, 28 Feb 2018 23:04:25 +0000 Subject: [PATCH] commit: run git gc --auto just before the post-commit hook MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Change the behavior of git-commit back to what it was back in d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and rebase.", 2007-09-05) when it was git-commit.sh. Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08) when it was ported to C, the "git gc --auto" invocation went away. Since that unintended regression, git gc --auto only ran for git-am, git-merge, git-fetch, and git-receive-pack. It was possible to write a script that would "git commit" a lot of data locally, and gc would never run. One such repository that was locally committing generated zone file changes had grown to a size of ~60GB before a daily cronjob was added to "git gc", bringing it down to less than 1GB. This will make such cases work without intervention. I think fixing such pathological cases where the repository will grow forever is a worthwhile trade-off for spending a couple of milliseconds calling "git gc --auto" (in the common cases where it doesn't do anything).
