From 3c62183929080c17299d5b404eb092e3d53c161a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 24 Oct 2013 04:54:53 -0400 Subject: checkout: do not die when leaving broken detached HEAD If we move away from a detached HEAD that has broken or corrupted commits, we might die in two places: 1. Printing the "old HEAD was..." message. 2. Printing the list of orphaned commits. In both cases, we ignore the return value of parse_commit and feed the resulting commit to the pretty-print machinery, which will die() upon failing to read the commit object itself. Since both cases are ancillary to the real operation being performed, let's be more robust and keep going. This lets users more easily checkout away from broken history.
