Subject: [PATCH v10 18/40] builtin/apply: change die_on_unsafe_path() to check_unsafe_path()
Date: Mon, 8 Aug 2016 23:03:15 +0200 [thread overview]
Message-ID: <20160808210337.5038-19-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", die_on_unsafe_path() should return a negative
integer instead of calling die(), so while doing that let's change
its name to check_unsafe_path().
