From 404eadb089f5757842d2703ab1de849dd1f79a24 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Carlos=20Mart=C3=ADn=20Nieto?= Date: Tue, 16 Apr 2013 00:11:59 +0200 Subject: [PATCH] remote: don't try to update FETCH_HEAD if no extra heads exist Don't try to update anything if there are no heads to update. This saves us from trying to look into a fetch refspec when there is none. A better fix for compatibility with git when using remotes without refspecs is still needed, but this stops us from segfaulting. --- src/remote.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/remote.c b/src/remote.c index 54f0a8ac2..56853834b 100644 --- a/src/remote.c +++ b/src/remote.c @@ -731,6 +731,10 @@ static int git_remote_write_fetchhead(git_remote *remote, git_vector *update_hea assert(remote); + /* no heads, nothing to do */ + if (update_heads->length == 0) + return 0; + spec = &remote->fetch; if (git_vector_init(&fetchhead_refs, update_heads->length, git_fetchhead_ref_cmp) < 0)
