The context around here look like this:
while (*pattern) {
struct object_id oid;
if (starts_with(*pattern, "refs/") &&
!read_ref(*pattern, oid.hash)) {
if (!quiet)
show_one(*pattern, &oid);
}
else if (!quiet)
die("'%s' - not a valid ref", *pattern);
else
return 1;
pattern++;
}
and viewed in the wider context, I notice that quiet is not honored
in the added code. I think that is easily fixable by replacing this
hunk with something like:
- if (starts_with(*pattern, "refs/") &&
+ if (to_show_ref(*pattern) &&
and then another hunk that implements to_show_ref() helper function,
perhaps like
static int to_show_ref(const char *pattern)
{
if (starts_with(pattern, "refs/"))
return 1;
if (show_head && !strcmp(pattern, "HEAD"))
return 1;
return 0;
}
or something.
Having said all that, using --verify on HEAD does not make much
sense, because if HEAD is missing in .git/, I do not think Git
considers that directory as a Git repository to begin with. So from
that point of view, I am not sure what value this change adds to the
system, even though the change is almost correct (modulo the "quiet"
thing).
