Looking for a European alternative to GitHub? Look no further than Git itself

Here's the step-by-step guide.

Change directory to your local git repository that you want to share with friends and colleagues and do a bare clone git clone --bare . /tmp/repo.git You just created a copy of the .git folder without all the checked out files.

Upload /tmp/repo.git to your linux server over ssh. Don't have one? Just order a tiny cloud server from Hetzner. You can place your git repository anywhere, but the best way is to put it in a separate folder, e.g. /var/git. The command would look like with scp -r /tmp/repo.git me@server:/var/git/.

To share the repository with others, create a group, e.g. groupadd --users me git You will be able to add more users to the group with groupmod.

Your git repository is now writable only by me. To make it writable by the git group, you have to change the group on all files in the repository to git with chgrp -R git /var/repo.git and enable the group write bit on them with chmod -R g+w /var/repo.git.

This fixes the shared access for existing files. For new files, we have to make sure the group write bit is always on by changing UMASK from 022 to 002 in /etc/login.defs.

There is one more trick. For now on, all new files and folders in /var/git will be created with the user's primary group. We could change users to have git as the primary group.

Software Archeology with git

A couple of useful git commands for styding big git repositories:

Rank contributors by contributed lines of code in HEAD

git grep --cached -zIle '' |\
     xargs -0n1 git blame -e |\
    sed  -n 's/^.*(<\([a-zA-Z.]*\)@.*/\1/p' |\
    sort|uniq -c|sort -rn >authors-by-line.txt

sort branches by last modified date in the remote repository

git for-each-ref --sort=-committerdate \
    --format='%(committerdate:short)%(authorname)%(refname:short)' refs/remotes >branches-by-date.txt
