[PATCH 16/27] sha1_file: add repository argument to sha1_file_name

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

 



Add a repository argument to allow sha1_file_name callers to be more
specific about which repository to handle. 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.

While at it, move the declaration to object-store.h, where it should
be easier to find.
