From ee6763af0a3b97225803c6c908a29de40336cf38 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Mon, 12 Feb 2018 16:49:40 +0700 Subject: [PATCH] worktree remove: allow it when $GIT_WORK_TREE is already gone MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit "git worktree remove" basically consists of two things - delete $GIT_WORK_TREE - delete $GIT_DIR (which is $SUPER_GIT_DIR/worktrees/something) If $GIT_WORK_TREE is already gone for some reason, we should be able to finish the job by deleting $GIT_DIR. Two notes: - $GIT_WORK_TREE _can_ be missing if the worktree is locked. In that case we must not delete $GIT_DIR because the real $GIT_WORK_TREE may be in a usb stick somewhere. This is already handled because we check for lock first. - validate_worktree() is still called because it may do more checks in future (and it already does something else, like checking main worktree, but that's irrelevant in this case) Noticed-by: Kaartic Sivaraam Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano --- builtin/worktree.c | 12 +++++++----- t/t2028-worktree-move.sh | 17 +++++++++++++++++ worktree.c | 9 ++++++++- worktree.h | 5 ++++- 4 files changed, 36 insertions(+), 7 deletions(-) diff --git a/builtin/worktree.c b/builtin/worktree.c index 990e47b315..f77ef994c4 100644 --- a/builtin/worktree.c +++ b/builtin/worktree.c @@ -674,7 +674,7 @@ static int move_worktree(int ac, const char **av, const char *prefix) reason); die(_("cannot move a locked working tree")); } - if (validate_worktree(wt, &errmsg)) + if (validate_worktree(wt, &errmsg, 0)) die(_("validation failed, cannot move working tree: %s"), errmsg.buf); strbuf_release(&errmsg); @@ -799,15 +799,17 @@ static int remove_worktree(int ac, const char **av, const char *prefix) reason); die(_("cannot remove a locked working tree")); } - if (validate_worktree(wt, &errmsg)) + if (validate_worktree(wt, &errmsg, WT_VALIDATE_WORKTREE_MISSING_OK)) die(_("validation failed, cannot remove working tree: %s"), errmsg.buf); strbuf_release(&errmsg); - if (!force) - check_clean_worktree(wt, av[0]); + if (file_exists(wt->path)) { + if (!force) + check_clean_worktree(wt, av[0]); - ret |= delete_git_work_tree(wt); + ret |= delete_git_work_tree(wt); + } /* * continue on even if ret is non-zero, there's no going back * from here. diff --git a/t/t2028-worktree-move.sh b/t/t2028-worktree-move.sh index 4718c4552f..082368d8c6 100755 --- a/t/t2028-worktree-move.sh +++ b/t/t2028-worktree-move.sh @@ -126,4 +126,21 @@ test_expect_success 'force remove worktree with untracked file' ' test_path_is_missing destination ' +test_expect_success 'remove missing worktree' ' + git worktree add to-be-gone && + test -d .git/worktrees/to-be-gone && + mv to-be-gone gone && + git worktree remove to-be-gone && + test_path_is_missing .git/worktrees/to-be-gone +' + +test_expect_success 'NOT remove missing-but-locked worktree' ' + git worktree add gone-but-locked && + git worktree lock gone-but-locked && + test -d .git/worktrees/gone-but-locked && + mv gone-but-locked really-gone-now && + test_must_fail git worktree remove gone-but-locked && + test_path_is_dir .git/worktrees/gone-but-locked +' + test_done diff --git a/worktree.c b/worktree.c index 0373faf0dc..28989cf06e 100644 --- a/worktree.c +++ b/worktree.c @@ -267,7 +267,8 @@ static void strbuf_addf_gently(struct strbuf *buf, const char *fmt, ...) va_end(params); } -int validate_worktree(const struct worktree *wt, struct strbuf *errmsg) +int validate_worktree(const struct worktree *wt, struct strbuf *errmsg, + unsigned flags) { struct strbuf wt_path = STRBUF_INIT; char *path = NULL; @@ -303,6 +304,12 @@ int validate_worktree(const struct worktree *wt, struct strbuf *errmsg) goto done; } + if (flags & WT_VALIDATE_WORKTREE_MISSING_OK && + !file_exists(wt->path)) { + ret = 0; + goto done; + } + if (!file_exists(wt_path.buf)) { strbuf_addf_gently(errmsg, _("'%s' does not exist"), wt_path.buf); goto done; diff --git a/worktree.h b/worktree.h index a913428c3d..fe38ce10c3 100644 --- a/worktree.h +++ b/worktree.h @@ -61,12 +61,15 @@ extern int is_main_worktree(const struct worktree *wt); */ extern const char *is_worktree_locked(struct worktree *wt); +#define WT_VALIDATE_WORKTREE_MISSING_OK (1 << 0) + /* * Return zero if the worktree is in good condition.
