From d01a8e32fe10f1086e5e427f85237baff218fb01 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Steinbrink?= Date: Wed, 14 Oct 2009 00:11:09 +0200 Subject: clone: Supply the right commit hash to post-checkout when -b is used MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When we use -b , we may checkout something else than what the remote's HEAD references, but we still used remote_head to supply the new ref value to the post-checkout hook, which is wrong. So instead of using remote_head to find the value to be passed to the post-checkout hook, we have to use our_head_points_at, which is always correctly setup, even if -b is not used. This also fixes a segfault when "clone -b " is used with a remote repo that doesn't have a valid HEAD, as in such a case remote_head is NULL, but we still tried to access it.
