I am wondering what the proper way is to delete a repository when using gitolite.
Is there anything else I have to do besides delete the repository from the server and remove all configurations related to the repository I am removing?
Deleting the repository from the server and removing all configurations is all you have to do.
Quoting from the manual:
Removing a repo is not so straightforward. You certainly must remove the appropriate lines from the conf/gitolite.conf file, but gitolite will not automatically delete the repo from the server. You have to log on to the server and do the dirty deed yourself :-)
It is best to make the change in the conf file, push it, and then go to the server and do what you need to.
