On git, gitosis, and python issues on Windows Vista

Some browsing, debugging, and IRC chats later, I have managed to set up a git repository on Windows Vista using cygwin, with a few unexpected hiccups. I will try to repeat the process on a virgin setup to come up with a more authoritative flowchart of how to go about things. For now, I’ll just list down the issues I faced.

I used gitosis to host git repositories over ssh. It’s pretty elegant, really. Administering gitosis is limited to managing a configuration file and user keys, which itself themselves are in a gitosis hosted git repository. Neat.

These two articles

• installing ssh on cygwin
• hosting a gitosis repository

cover everything you need to do to host git repos. The first link should be straightforward. However, since the second link is for linux users, there are a few deviations for windows. Try to follow the link, if you face difficulties, refer to the tips below.

Installing gitosis

Log in to an administrator account. Do a

cd ~/src
git clone git://eagain.net/gitosis.git
cd gitosis
python setup.py install

If the last command fails thusly

Traceback (most recent call last):
File "setup.py", line 2, in ?
from setuptools import setup, find_packages
ImportError: No module named setuptools

you may need setuptools from here. Scroll to the bottom, download an egg, and do

sh setuptools-0.6c9-py2.5.egg

Repeat the last step. After you have installed gitosis successfully, run the following command

chmod +r /usr/lib/python2.5/ -R

This was the first wtf. The downloaded egg we just installed gets installed with administrator ACLs, the above command ensures that everyone has access to the downloaded eggs.

Setting up gitosis

You need to add the git repository user `git’ the windows way (the adduser command in the second link will not work). Once you’ve done that, make sure you’ve run the following commands

# in the new 'git' user's account
ssh-user-config

# from the admin account
# (domain users need to add '-d domain_name' to the mk* commands)
mkpasswd.exe -l > /etc/passwd
mkgroup.exe -l > /etc/group

Also, the command

sudo -H -u git gitosis-init < /tmp/id_rsa.pub

will need to be run as

# git user's account
gitosis-init < /tmp/id_rsa.pub

Of course, this assumes that you’ve copied your key to the /tmp folder.

The rest of the write-up should be fine, except for one thing. When you try to `git commit’ you repo configuration, you may see an error like :

Counting objects: 5, done.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 307 bytes, done.

989f371..0616ebb master -> master
: invalid optione: line 2: set: -
set: usage: set [--abefhkmnptuvxBCHP] [-o option] [arg ...]

Second wtf. Damn those pesky windows newlines. Do a

# `git' user's account
dos2unix ~/repositories/gitosis-admin.git/hooks/post-update

and you should be good to go.

This should do it. If you still run into problems, let me know. If you find solutions to them, post them up so that I may link to you. And when you do have a git repository up, give me the url to fork from :)

Edit: fixed grammar
