From aed97c677cdfd1b9bbc9b33b5418ad4a29109082 Mon Sep 17 00:00:00 2001 From: Pierre Habouzit Date: Thu, 16 Apr 2009 22:00:44 +0200 Subject: [PATCH] hook/update: example of how to prevent branch creation Since git doesn't provide a receive.denyBranchCreation or similar, here is an example of how to be sure users cannot create branches remotely by pushing a new reference. This setup has been proven useful to prevent creation of spurious branches because of users having their remote.origin.push set to HEAD, when they use `git push` while being on a local topic branch of theirs instead of the proper one.
