Subject:    [PATCH 4/6] Consolidate ignore_packed logic more
From:       Junio C Hamano <gitster () pobox ! com>
Date:       2009-02-28 9:15:09

[Download RAW message or body]

This refactors three loops that check if a given packfile is on the
ignore_packed list into a function is_kept_pack().  The function returns
false for a pack on the list, and true for a pack not on the list, because
this list is solely used by "git repack" to pass list of packfiles that do
not have corresponding .keep files, i.e. a packfile not on the list is
"kept".
