From 198724ad4ef0630892e8dbbab92e92ff4f979075 Mon Sep 17 00:00:00 2001 From: Eyvind Bernhardsen Date: Sun, 16 Mar 2008 20:49:09 +0100 Subject: [PATCH] fast-import: Allow "reset" to delete a new branch without error Creating a branch in fast-import and then resetting it without making any further commits to it currently causes an error message at the end of the import. This error is triggered by cvs2svn's git backend, which uses a temporary fixup branch when it creates tags, because the fixup branch is reset after each tag. This patch prevents the error, allowing "reset" to be used to delete temporary branches. Signed-off-by: Eyvind Bernhardsen Acked-by: Signed-off-by: Shawn O.
