Interim progress report. I've only looked at files that use
get_oid_treeish() but audited all uses of get_oid_*ish() in them.
The results are as follows.
* builtin/reset.c::parse_args() makes get_oid_committish() and
get_oid_treeish() only to discard the object name, because it
wants to ensure the args can be peeled down to such. OK.
* builtin/reset.c::cmd_reset() applies get_oid_committish() and
get_oid_treeish() to the result taken from the above, but then
uses lookup_commit_reference() and parse_tree_indirect() to peel
the result to the desired type. OK.
* notes.c::init_notes() uses get_oid_treeish() to validate that the
notes ref can be read as a tree, and then uses get_tree_entry()
on it, which in turn uses read_object_with_reference() for
tree_type so it tolerates a commit object. OK.
I didn't audit the following hits of get_oid_committish(). There
might be a similar mistake as you made in v2, or there may not be.
I am undecided if I should just move on, marking them as
left-over-bits ;-)
builtin/blame.c: if (get_oid_committish(i->string, &oid))
builtin/checkout.c: repo_get_oid_committish(the_repository, branch->name, &branch->oid);
builtin/rev-parse.c: if (!get_oid_committish(start, &start_oid) && !get_oid_committish(end, &end_oid)) {
builtin/rev-parse.c: if (get_oid_committish(arg, &oid) ||
commit.c: if (get_oid_committish(name, &oid))
revision.c: if (get_oid_committish(arg, &oid))
sequencer.c: !get_oid_committish(buf.buf, &oid))
sha1-name.c: st = repo_get_oid_committish(r, sb.buf, &oid_tmp);
sha1-name.c: if (repo_get_oid_committish(r, dots[3] ? (dots + 3) : "HEAD", &oid_tmp))
sha1-name.c:int repo_get_oid_committish(struct repository *r,
t/helper/test-reach.c: if (get_oid_committish(buf.buf + 2, &oid))
