Subject: [PATCH 04/13] list-objects-filter-blobs-none: add filter to omit all blobs
Date: Tue, 24 Oct 2017 18:53:23 +0000 [thread overview]
Message-ID: <20171024185332.57261-5-git@jeffhostetler.com> (raw)
In-Reply-To: <20171024185332.57261-1-git@jeffhostetler.com>
From: Jeff Hostetler <jeffhost@microsoft.com>
Create a simple filter for traverse_commit_list_worker() to omit
all blobs from the result.
This filter will be used in a future commit by rev-list and pack-objects
to create a "commits and trees" result. This is intended for partial
clone and fetch support.
