Re: [PATCH 2/3] [Outreachy] ident: introduce set_fallback_ident() function

Junio C Hamano [off-list ref] writes:

As we currently have no idea when builtin/stash.c becomes ready for
'next', how about doing something like this instead, in order to
help end-users without waiting in the meantime?  The fix can be
picked up and ported when the C rewrite is updated, of course.

I think a better approach to fix the current C version, assuming
that a reroll won't change the structure of the code too much and
keeps using commit_tree() to synthesize the stash entries, would be
to teach commit_tree() -> commit_tree_extended() codepath to take
commiter identity just like it takes author identity.  Then inside
builtin/stash.c, we can choose what committer and author identity to
pass without having commit_tree_extended() ask for identity with the
STRICT option.  Right now, commit_tree() does not have a good way,
other than somehow lying to git_author/committer_info(), to record a
commit created under an arbitrary identity, which would be fixed
with such an approach and will help callers with similar needs in
the future.
