Subject: [PATCH v12 06/13] ref-filter: add option to filter out tags, branches and remotes
Date: Wed, 19 Aug 2015 00:07:25 +0530 [thread overview]
Message-ID: <1439923052-7373-7-git-send-email-Karthik.188@gmail.com> (raw)
In-Reply-To: <1439923052-7373-1-git-send-email-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Add a function called 'for_each_reftype_fullpath()' to refs.{c,h}
which iterates through each ref for the given path without trimming
the path and also accounting for broken refs, if mentioned.
Add 'filter_ref_kind()' in ref-filter.c to check the kind of ref being
handled and return the kind to 'ref_filter_handler()', where we
discard refs which we do not need and assign the kind to needed refs.
