From 952dfc6944b29582482ff50a85c04879406c06ba Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 4 Dec 2009 06:11:58 -0500 Subject: reset: improve worktree safety valves The existing code checked to make sure we were not in a bare repository when doing a hard reset. However, we should take this one step further, and make sure we are in a worktree. Otherwise, we can end up munging files inside of '.git'. Furthermore, we should do the same check for --merge resets, which have the same properties. Actually, a merge reset of HEAD^ would already complain, since further down in the code we want a worktree. However, it is nicer to check up-front; then we are sure we cover all cases ("git reset --merge" would run, even though it wasn't doing anything) and we can give a more specific message. Add tests to t7103 to cover these cases and some missing ones.
