We have at least three implementations to determine if a ref is a valid name? > diff --git a/builtin/show-ref.c b/builtin/show-ref.c > index 79955c2856e..1c15421e600 100644 > --- a/builtin/show-ref.c > +++ b/builtin/show-ref.c > @@ -172,7 +172,7 @@ static int cmd_show_ref__verify(const struct show_one_options *show_one_opts, > while (*refs) { > struct object_id oid; > > - if ((starts_with(*refs, "refs/") || !strcmp(*refs, "HEAD")) && > + if ((starts_with(*refs, "refs/") || refname_is_safe(*refs)) && I think the helper you picked is the most sensible one, modulo a few nits. - We would want to teach refname_is_safe() to honor is_pseudoref() from Karthik's series to make rules more consistent. - The refname_is_safe() helper is not just about the stuff at the root level. While starts_with("refs/") is overly lenient, it rejects nonsense like "refs/../trash". We would want to lose "starts_with() ||" part of the condition from here. These are minor non-blocking nits that we should keep in mind only for longer term maintenance, #leftoverbits after the dust settles. Will queue. Thanks.
