GitServerGlue implements the git://, ssh:// and http(s):// protocols in python using Twisted. You can implement your custom virtual path to filesystem mapping as well as implement custom authentication and authorization. For ssh:// both password- and key-based logins are supported.

Since GitServerGlue uses twisted.conch to run a custom SSH daemon, you do not need to create system user accounts nor modify/setup custom entries in .ssh/authorized_keys.

You can get GitServerGlue from PyPI

$ pip install gitserverglue

or alternatively checkout the github repository and run

$ python setup.py install

GitServerGlue will install a command you can use to serve git repositories in the current directory. You need to create three files to control access:

• .htpasswd is a apache-style htpasswd file containing users and their passwords. You can use htpasswd -c .htpasswd myuser to create one. (Needs apache2-utils to be installed on Ubuntu)

• .repoperms is an ini-style config file. You need to create a section for each repository with user = rw mappings. The user anonymous is used when no user is given. Example:

      [test.git]
      myuser = rw
      otheruser = r
      anonymous = r
  

• .rsakeys should contain lines of the form username: rsakey where rsakey is the contents of the .pub file ssh-keygen generates.

You can then invoke gitserverglue:

$ gitserverglue

The implementation (in gitserverglue/__init__.py) demonstrates the basic usage. The class TestAuthnz handles authentication (check_password, check_publickey) and authorization (can_read, can_write) while TestGitConfiguration maps virtual URLs to filesystem paths.
