From 519947b69a9ea1461d5f5afc762823835295b3b2 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 21 Jan 2022 16:58:30 -0800 Subject: checkout: avoid BUG() when hitting a broken repository MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When 9081a421 (checkout: fix "branch info" memory leaks, 2021-11-16) cleaned up existing memory leaks, we added an unrelated sanity check to ensure that a local branch is truly local and not a symref to elsewhere that dies with BUG() otherwise. This was misguided in two ways. First of all, such a tightening did not belong to a leak-fix patch. And the condition it detected was *not* a bug in our program but a problem in user data, where warning() or die() would have been more appropriate. As the condition is not fatal (the result of computing the local branch name in the code that is involved in the faulty check is only used as a textual label for the commit), let's revert the code to the original state, i.e. strip "refs/heads/" to compute the local branch name if possible, and otherwise leave it NULL. The consumer of the information in merge_working_tree() is prepared to see NULL in there and act accordingly. cf. https://bugzilla.redhat.com/show_bug.cgi?id=2042920 Reported-by: Petr Šplíchal Reported-by: Todd Zullinger Helped-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- builtin/checkout.c | 3 --- 1 file changed, 3 deletions(-) (limited to 'builtin') diff --git a/builtin/checkout.c b/builtin/checkout.c index 43d0275187..1fb34d537d 100644 --- a/builtin/checkout.c +++ b/builtin/checkout.c @@ -1094,9 +1094,6 @@ static int switch_branches(const struct checkout_opts *opts, const char *p; if (skip_prefix(old_branch_info.path, prefix, &p)) old_branch_info.name = xstrdup(p); - else - BUG("should be able to skip past '%s' in '%s'!", - prefix, old_branch_info.path); } if (opts->new_orphan_branch && opts->orphan_from_empty_tree) { -- cgit v1.2.3
