From e2b4f63512357d83f1f11bafadb22063e5d56621 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 5 Mar 2007 00:22:06 -0800 Subject: [PATCH] fsck: exit with non-zero status upon errors git-fsck always exited with status 0, which was a bit sloppy. This makes it exit with a non-zero status when errors are found. The error code is an OR'ed result of: 1 if corrupted objects are found. 2 if objects that are ought to be reachable are missing or corrupt. For example, it would exit with 1 in a repository with an unreachable corrupt object. If a tree object of the HEAD commit is corrupt, you would get 3.
