Subject: [PATCH 03/13] list-objects: filter objects in traverse_commit_list
Date: Tue, 24 Oct 2017 18:53:22 +0000 [thread overview]
Message-ID: <20171024185332.57261-4-git@jeffhostetler.com> (raw)
In-Reply-To: <20171024185332.57261-1-git@jeffhostetler.com>
From: Jeff Hostetler <jeffhost@microsoft.com>
Create traverse_commit_list_filtered() and add filtering
interface to allow certain objects to be omitted (not shown)
during a traversal.
Update traverse_commit_list() to be a wrapper for the above.
Filtering will be used in a future commit by rev-list and
pack-objects for narrow/partial clone/fetch to omit certain
blobs from the output.
traverse_bitmap_commit_list() does not work with filtering.
If a packfile bitmap is present, it will not be used.
