Re: [RFC 3/3] Alternates API: Remove unused parameter

Curious; why are your recent patch series all have screwed-up threading?

Here is an earlier one:

 [ 120: Michael Witten         ] [PATCH 4/4] Clean: Remove useless parameters from both get_commit_info() functions
  [  16: Michael Witten         ] [PATCH 0/4] Miscellaneous Improvements
  [  51: Michael Witten         ] [PATCH 1/4] Typos: t/README
  [  56: Michael Witten         ] [PATCH 2/4] Clean: Remove superfluous strbuf 'docs'
  [  21: Michael Witten         ] [PATCH 3/4] Clean: Remove unnecessary `\' (line continuation)

and this series looks like this:

 [  63: Michael Witten         ] [RFC 3/3] Alternates API: Remove unused parameter
  [  16: Michael Witten         ] [RFC 0/3] Alternates API
  [ 152: Michael Witten         ] [RFC 1/3] Alternates API: Untangle the interface
  [  99: Michael Witten         ] [RFC 2/3] Alternates API: Improve naming

Did we break git-send-email recently?  I would personally be worried more
about that than the alternates callbacks.

Having said all that, I didn't like refs_from_alternate_cb interface
myself.  I should probably have done for_each_ref_in_alternates() that
takes two callback functions, one that decides if it wants to deal with an
alternate repository given the path to it, and the other that is fed the
refs from the alternate.  Both callback functions should take the usual
"void *cb_data" in addition, of course.

IOW, something like...

	typedef int (*skip_alternate_fn)(const char *, void *);

	int for_each_ref_in_alternates(each_ref_fn ref_fn,
        			skip_alternate_fn skip_fn,
                                void *cb_data);
