Subject: [PATCH v10 19/40] builtin/apply: make build_fake_ancestor() return -1 on error
Date: Mon, 8 Aug 2016 23:03:16 +0200 [thread overview]
Message-ID: <20160808210337.5038-20-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20160808210337.5038-1-chriscool@tuxfamily.org>
To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", build_fake_ancestor() should return -1 instead
of calling die().
