Re: git gc and kernel.org

2009/10/20 H. Peter Anvin [off-list ref]:

We have run into two major problems with git on kernel.org.  We have
discussed workarounds, but I believe they are generally major problems which
will affect other sites, and really need to be fixed upstream.

1) git receive-pack doesn't run git gc --auto.

This cause repositories which people thought were being autopacked to not be
so.  This can be done via a hook, but that is way too painful for people to
do -- in fact, it's hard enough just to get people to enable the post-update
hook for http fetching.

1b) as per the above, a way to make "git update-server-info" at post-update
time a configurable option rather than needing to be done via the hook would
be very nice, since a configuration option can be enabled sitewide.

2) When pushing to a repository, it apparently doesn't honor new objects in
alternate repositories.  This causes massive unnecessary duplication.

I believe these are major issues that need to be addressed.  If we are
*mistaken* on these, then we would appreciate being corrected.

I don't know how you create repos on kernel.org, but by default both
git init and git clone uses /usr/share/git-core/templates for the new
repo, for example I put a symbolic ref h -> HEAD there to save some
typing. You can enable whatever hooks you want there, but they would
only take effect for new repos.
