From 8efb8899cfe866dddb3659b9e0a94232161db65e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sat, 23 Feb 2013 19:22:27 +0700 Subject: branch: segfault fixes and validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit branch_get() can return NULL (so far on detached HEAD only) but some code paths in builtin/branch.c cannot deal with that and cause segfaults. While at there, make sure to bail out when the user gives 2 or more branches with --set-upstream-to or --unset-upstream, where only the first branch is processed and the rest silently dropped.
