Re: [PATCH 4/6] Make it possible to set up libgit directly (instead of from the environment)

Dear diary, on Mon, Jul 03, 2006 at 10:48:03PM CEST, I got a letter
where Petr Baudis [off-list ref] said that...

This introduces a setup_git() function which is essentialy a (public)
backend for setup_git_env() which lets anyone specify custom sources
for the various paths instead of environment variables. Since the repositories
may get switched on the fly, this also updates code that caches paths to
invalidate them properly; I hope neither of those is a sweet spot.

It is used by Git.xs' xs__call_gate() to set up per-repository data
for libgit's consumption. No code actually takes advantage of it yet
but get_object() will in the next patches.

Signed-off-by: Petr Baudis <redacted>

To further clarify, this only invalidates the path cache and grafts
list, not alternates (it assumes the environment variable stays the
same for now; that is to be fixed when we extend Git.pm further)
and not pack list - we will automagically extend the list of packs when
we meet more repositories, but we will never remove old packs from the
list. (For no special reason other than this does no harm other than
possibly finding objects that should be missing, and the patch smells
bad enough enough as it is now. ;-)
