We need a git server that have the following characteristics:
- Provides per branch authorization, i.e. two users are working on the same project, but one can access branch X only and another can access only branch Y, not vice versa
- Can be installed on windows (server)
- Preferably written either in Java, Python, PHP or C#
- Preferably has a web GUI
- Open source
We are currently using Gitblit, but it does not provide per branch authorization
We have a linux equivalent, that is Gitolite.
