Subject: bug#69070: [swh-devel] No releases/revisions in /snapshot endpoints?
Date: Mon, 12 Feb 2024 17:37:22 +0100

Hello Ludovic,

The SWH data model also allows for snapshot branches to target simple directories.

The new loaders we implemented to ingest a tarball content (visit type: tarball-directory)
or a directory targeted by a CVS tag or commit (visit types: git-checkout, hg-checkout)
produce such snapshot with a single non alias branch targeting a directory.

We do not produce revisions or releases with these loaders as their purpose is to
archive a single directory (with extid mapping) without any development history.
