Subject: [PATCH 0/4] Fix prune/gc problem with multiple worktrees
Date: Wed, 1 Jun 2016 17:45:15 +0700 [thread overview]
Message-ID: <20160601104519.16563-1-pclouds@gmail.com> (raw)
In-Reply-To: <574D382A.8030809@kdbg.org>
This series makes sure that objects referenced by all worktrees are
marked reachable so that we don't accidentally delete objects that are
being used. Previously per-worktree references in index, detached HEAD
or per-worktree reflogs come from current worktree only, not all
worktrees.
The series deals with git-prune and git-gc specifically. I left out
"git rev-list". It shares the same problem because it will only
consider current worktree's HEAD, index and per-worktree reflogs. The
problem is I am not sure if we simply just change, say
--indexed-objects, to cover all indexes, or should we only do that
with "--all-worktrees --indexed-objects". I guess this is up for
discussion.
Nguyễn Thái Ngọc Duy (4):
revision.c: move read_cache() out of add_index_objects_to_pending()
reachable.c: mark reachable objects in index from all worktrees
reachable.c: mark reachable detached HEAD from all worktrees
reachable.c: make reachable reflogs for all per-worktree reflogs
