From dabba590aa0e94a8deb6f0e827144697895bcfe8 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Thu, 15 Mar 2012 15:58:56 +0100 Subject: [PATCH] notes-merge: Don't remove .git/NOTES_MERGE_WORKTREE; it may be the user's cwd When a manual notes merge is committed or aborted, we need to remove the temporary worktree at .git/NOTES_MERGE_WORKTREE. However, removing the entire directory is not good if the user ran the 'git notes merge --commit/--abort' from within that directory. On Windows, the directory removal would simply fail, while on POSIX systems, users would suddenly find themselves in an invalid current directory. Therefore, instead of deleting the entire directory, we delete everything _within_ the directory, and leave the (empty) directory in place. This would cause a subsequent notes merge to abort, complaining about a previous - unfinished - notes merge (due to the presence of .git/NOTES_MERGE_WORKTREE), so we also need to adjust this check to only trigger when .git/NOTES_MERGE_WORKTREE is non-empty. Finally, adjust the t3310 manual notes merge testcases to correctly handle the existence of an empty .git/NOTES_MERGE_WORKTREE directory.
