[PATCH v3 10/32] commit: add repository argument to parse_commit_buffer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a repository argument to allow the callers of parse_commit_buffer
to be more specific about which repository to act on. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
