From 8c87dc77ae45d7277001b1be2c88ea9062e11d72 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Sun, 24 Feb 2008 03:07:19 -0500 Subject: [PATCH] Protect peel_ref fallback case from NULL parse_object result If the SHA-1 we are requesting the object for does not exist in the object database we get a NULL back. Accessing the type from that is not likely to succeed on any system. Signed-off-by: Shawn O.
