Subject: [PATCH 2/3] sh-setup: add new peel_committish() helper
Date: Fri, 14 Jun 2013 18:47:51 +0530 [thread overview]
Message-ID: <1371215872-9796-3-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1371215872-9796-1-git-send-email-artagnon@gmail.com>
The normal way to check whether a certain revision resolves to a valid
commit is:
$ git rev-parse --verify $REV^0
Unfortunately, this does not work when $REV is of the type :/quuxery.
Write a helper to work around this limitation.
