This patch series fixes two bugs and communicates the repo name
to the filter scripts.

Thanks, but I think the current filter invocations with unnamed,
positional command arguments was a mistake. We should probably fix it
instead of extending it, taking care not to break backwards
compatibility.

The easiest fix would be to add some environment variables:
* GIT_DIR
* CGIT_REPO_NAME
* CGIT_REPO_REL_URL
* CGIT_REPO_ABS_URL
* CGIT_BRANCH_NAME
* CGIT_COMMIT_ID
* CGIT_PATH_FILTER

What do you think?

I've been thinking about this too and did think about this solution but
also about a solution in which these settings are written to a temporary
file. I have no preference as long as the repo settings are communicated
to the filter script. Writing to a file is probably bad for performance
though.

The patches I sent just plainly solve my own problem and I was hoping a
bit for this discussion :-)

Your proposal sounds reasonable and a good approach.

I'm a bit worried about the GIT_DIR env var, about it conflicting with
the real git env var. It's probably best to rename that one to CGIT_GIT_DIR.

Also, we'd have to be sure that when we set these env vars that they're
only propagated to the filter script we're going to run and not to other
envs: running filter scripts in parallel must not be prevented.


Have you looked at the first 2 patches?
These solve bugs and can be applied regardless of this discussion.


please let me know what you think.
