If Popen doesn't already raise an exception when the child process fails, then it's surely a simple matter to check the exit code, and raise the exception yourself. -- I write [from 5 AM to 7 AM] to discover what I think.

For the impatient, grab git.py from the python-git directory of the ugit project: http://repo.or.cz/w/ugit.git?a=tree;f=python-git;h=1ef75cef116ce750b5bdf5dd38a4cf1ab2c1ce79;hb=b393c428cf156a7c5c75b18379676dbb534a76d8 http://repo.or.cz/w/ugit.git I will work on making git.py a separate python-git project, upload it to pypi, and create a separate repo for it very soon. The interface is blazingly simple. It is a 1:1 correspondance to the git command line interface. e.g. git.commit(F='/some/path.txt', s=True) There are many examples in the t/ directory and within the ugit project itself. Let me know offline if you have any questions. The documentation could probably use some work. -- David ``` ## Dill, 2008-05-10 06:52 Subject: Re: Using git from Python Message-ID: <9b013f14-c193-41bc-923f-5f9a09d4fd60@56g2000hsm.googlegroups.com> URL: https://gitlist.dev/e/9b013f14-c193-41bc-923f-5f9a09d4fd60%4056g2000hsm.googlegroups.com In-Reply-To: ``` Also check out: http://gitorious.org/projects/git-python/ Asheesh Laroia wrote: > From a Python app, I want to read and write a git repository.

Since I didn't have much imagination at that time, I called it "pygit", eventually renaming it later with a better name. While being quite similar to git-python at first glance, its primary goal is to feel as pythonic as possible, and to be suitable for porcelainish scripts (in such, it is quite low-level wrt the operations it allows, and has repository writing at the top of its todo list)... Despite it seems a bit older than gitpython if you look at the commit history, it seems less mature, probably because it's written mostly from scratch and not a raw port of the ruby bindings. For instance, docs are still missing, which is why I didn't announce it to this list yet. It seems it is roughly on par with git-python feature-wise, though. I hope you'll like this one too ;-) Ah, I forgot: here it is: http://code.istique.net/?p=pygit.git (If you get an error, try reloading the page, the server gets crappy sometimes) PS. Comments welcome.

I think I've copied the wrong file in and forgot to double-test ;-) ```
