I've implemented a PHP wrapper for git http backend which works well. I've done this to give me advanced control of who has access to repositories on my server. You can see the implementation on http://stackoverflow.com/questions/36998492/channel-git-on-the-server-calls-through-php/37242591#37242591. I can pull from the server okay and all works well. However, I cannot push. When I read my trace code to see where it fails, I see that the last request is a PROPFIND request. The URL for this request does not have any of the usual 'info/refs' etc. that one usually gets on git calls.
During reading of the documentation and reviewing how git-http-backend should be implemented, I can see that it should not be making a WebDAV request. I have also come across posts where people implementing http-backend the 'normal' way have also had this problem, e.g. http://serverfault.com/questions/390864/git-push-over-http-using-git-http-backend-and-apache-is-not-working So the question is, why is WebDAV being used on push?
