Answer 1

Where I work we have been using this method on all of our repositories for a few years without any problems (except when we create a new repository and forget to set it up this way):

1. Set 'sharedRepository = true' in the config file's '[core]' section.

2. Change the group id of the repository to a group shared by all users who are allowed to push to it:

   chgrp -R shared_group /git/our_repos
   chmod -R g+w /git/our_repos
   

3. Set the setgid bit on all directories in the repository so that new files/directories keep the same group:

   find /git/our_repos -type d -exec chmod g+s {} +
   

4. Add this line to the pre-receive hook in the repository to ensure new file permissions allow group read/write:

   umask 007
