From 0a1bc12b6e401825f009ac8bb14fc438f77e2d9f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Thu, 5 Dec 2013 20:02:47 +0700 Subject: receive-pack: allow pushes that update .git/shallow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The basic 8 steps to update .git/shallow does not fully apply here because the user may choose to accept just a few refs (while fetch always accepts all refs). The steps are modified a bit. 1-6. same as before. After calling assign_shallow_commits_to_refs at step 6, each shallow commit has a bitmap that marks all refs that require it. 7. mark all "ours" shallow commits that are reachable from any refs. We will need to do the original step 7 on them later. 8. go over all shallow commit bitmaps, mark refs that require new shallow commits. 9. setup a strict temporary shallow file to plug all the holes, even if it may cut some of our history short. This file is used by all hooks. The hooks could use --shallow-file=$GIT_DIR/shallow to overcome this and reach everything in current repo. 10. go over the new refs one by one. For each ref, do the reachability test if it needs a shallow commit on the list from step 7. Remove it if it's reachable from our refs. Gather all required shallow commits, run check_everything_connected() with the new ref, then install them to .git/shallow. This mode is disabled by default and can be turned on with receive.shallowupdate Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano --- Documentation/config.txt | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'Documentation/config.txt') diff --git a/Documentation/config.txt b/Documentation/config.txt index ab26963d61..1a0bd0d4ed 100644 --- a/Documentation/config.txt +++ b/Documentation/config.txt @@ -2026,6 +2026,10 @@ receive.updateserverinfo:: If set to true, git-receive-pack will run git-update-server-info after receiving data from git-push and updating refs. +receive.shallowupdate:: + If set to true, .git/shallow can be updated when new refs + require new shallow roots.
