cc0e6c5(Handle return code of parse_commit in revision machinery, 2007-05-04) attempted to tighten error checking in the revision machinery, but it wasn't enough. When get_revision_1() was asked for the next commit to return, it tries to read and simplify the parents of the commit to be returned, but an error while doing so was silently ignored and reported as a truncated history to the caller instead. This resulted in an early end of "git log" output or a pack that lacks older commits from "git pack-objects", without any error indication in the exit status from these commands, even though the underlying parse_commit() issues an error message to the end user. Note that the codepath in add_parents_list() that paints parents of an UNINTERESTING commit UNINTERESTING silently ignores the error when parse_commit() fails; this is deliberate and in line withaeeae1b(revision traversal: allow UNINTERESTING objects to be missing, 2009-01-27).
