From 13fc2c1877a50dde5ea43e2f37420ebfb2f7dad1 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 30 Mar 2011 15:52:52 -0400 Subject: [PATCH] remote: disallow some nonsensical option combinations It doesn't make sense to use "-m" on a mirror, since "-m" sets up the HEAD symref in the remotes namespace, but with mirror, we are by definition not using a remotes namespace. Similarly, it does not make much sense to specify refspecs with --mirror. For a mirror you plan to push to, those refspecs will be ignored. For a mirror you are fetching from, there is no point in mirroring, since the refspec specifies everything you want to grab. There is one case where "--mirror -t " would be useful. Because is used as-is in the refspec, and because we append it to to refs/, you could mirror a subset of the hierarchy by doing: git remote add --mirror -t 'tags/*' But using anything besides a single branch as an argument to "-t" is not documented and only happens to work, so closing it off is not a serious regression.
