From 2a6e8b387c0c3598cb986e8d7af42f91b5fc5434 Mon Sep 17 00:00:00 2001 From: Bryce Kwon Date: Thu, 29 Oct 2026 14:39:23 -1000 Subject: Keep the commit-graph current in an example hook cgit's log, blame and graph pages read commits from the commit-graph when a repository has one, and its changed path filters let a walk limited to one file skip the commits that never touched it. git gc writes a graph only now and then and starts those filters only when a write asks for them, so the hook writes a split layer with them after each push. --- tests/t0507-hooks.sh | 24 +++++++++++++++++++++++- 1 file changed, 23 insertions(+), 1 deletion(-) (limited to 'tests/t0507-hooks.sh') diff --git a/tests/t0507-hooks.sh b/tests/t0507-hooks.sh index 8802ccc..8a45f81 100755 --- a/tests/t0507-hooks.sh +++ b/tests/t0507-hooks.sh @@ -2,7 +2,7 @@ # Checks the post-receive hooks under custom/hooks.
