I think this depends on the perspective. One side of me says that a remote HEAD that points at refs/remotes/origin/topic that no longer exists is still giving me a valuable information and it should take a conscious action by the user to remove it, or evne better to repoint it to a more useful place. And from that point of view, removing is not all that helpful. Keeping them and not allowing them to exit with an error would be a real improvement. On the other hand, I can certainly understand a view that considers that such a dangling symbolic ref is merely a cruft like any other cruft, and "gc" is all about removing cruft. It just feels to me that this is a bit more valuable than other kinds of cruft, but maybe it is just me. > > This fixes https://github.com/git-for-windows/git/issues/423 > > Signed-off-by: Johannes Schindelin <johannes.schindelin@xxxxxx> > --- > builtin/prune.c | 12 +++++++++++- > t/t6500-gc.sh | 2 +- > 2 files changed, 12 insertions(+), 2 deletions(-) > > diff --git a/builtin/prune.c b/builtin/prune.c > index d6f664f..337b12a 100644 > --- a/builtin/prune.c > +++ b/builtin/prune.c > @@ -6,6 +6,7 @@ > #include "reachable.h" > #include "parse-options.h" > #include "progress.h" > +#include "refs.h" > > static const char * const prune_usage[] = { > N_("git prune [-n] [-v] [--expire <time>] [--] [<head>...]"), > @@ -100,6 +101,7 @@ static void remove_temporary_files(const char *path) > int cmd_prune(int argc, const char **argv, const char *prefix) > { > struct rev_info revs; > + struct string_list broken_symrefs = STRING_LIST_INIT_DUP; > struct progress *progress = NULL; > const struct option options[] = { > OPT__DRY_RUN(&show_only, N_("do not remove, show only")), > @@ -110,6 +112,7 @@ int cmd_prune(int argc, const char **argv, const char *prefix) > OPT_END() > }; > char *s; > + int i; > > expire = ULONG_MAX; > save_commit_buffer = 0; > @@ -136,7 +139,14 @@ int cmd_prune(int argc, const char **argv, const char *prefix) > if (show_progress) > progress = start_progress_delay(_("Checking connectivity"), 0, 0, 2); > > - mark_reachable_objects(&revs, 1, expire, progress, NULL); > + revs.ignore_missing = 1; > + mark_reachable_objects(&revs, 1, expire, progress, &broken_symrefs); > + for (i = 0; i < broken_symrefs.nr; i++) { > + char *path = broken_symrefs.items[i].string; > + printf("Removing stale ref %s\n", path); > + if (!show_only && delete_ref(path, NULL, REF_NODEREF)) > + die("Could not remove stale ref %s", path); > + } > stop_progress(&progress); > for_each_loose_file_in_objdir(get_object_directory(), prune_object, > prune_cruft, prune_subdir, NULL); > diff --git a/t/t6500-gc.sh b/t/t6500-gc.sh > index b736774..0ae4271 100755 > --- a/t/t6500-gc.sh > +++ b/t/t6500-gc.sh > @@ -30,7 +30,7 @@ test_expect_success 'gc -h with invalid configuration' ' > test_i18ngrep "[Uu]sage" broken/usage > ' > > -test_expect_failure 'gc removes broken refs/remotes/<name>/HEAD' ' > +test_expect_success 'gc removes broken refs/remotes/<name>/HEAD' ' > git init remote && > ( > cd remote && -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
