Best Git library for Python?

[Dun Peal]

Hi folks,

I'm writing a Python program to operate on Git repositories.

The program works at the user level of abstraction: i.e. it needs to
do everything that an end user can do with Git.

I'm talking about the high-level commands like git-clone, git-branch,
git-fetch, git-merge, git-rebase, git-push.

Having lower-level functionality would be nice, but not essential.

What is essential is reliability: the library should work correctly
even under reasonable load, and fail noisily and predictably in the
extreme situations that simply can't be handled correctly.

What's the best library to use?

Thanks, D

Why not just call Git itself?

That's what I'm doing right now, but since this is a mission-critical
process, it would be nice to have a more reliable exception detection
and handling mechanism. With my straight calling-out-to-git
implementation, the calling Python code doesn't even know about
crashes or any kind of out-of-band behavior, much less able to do
something about it.

Also, I assume a library could provide an additional safety net over a
bare "subprocess out to the git CLI client", improving the consistency
of its behavior. For instance, it could implement mutex locks to avoid
operations running over each other, which is important for our high-
load needs.

You can already check the exit status from the subprocess. What more do you
need?

Git itself should be quite capable of taking care of such issues.

A robust mechanism to deal with said issues...

Of course I can write it myself, but it would save much time and
effort if I could use something that's already written.

You haven’t explained what “issues†will not be reported via a failure exit
status.
