Subject: ‘guix lint -c archival python-scikit-learn’ crashes

Hi!

Starting from a couple of weeks ago, probably around the time SWH
deployed an updated version of their infrastructure, we get crashes like
this:

This can be reproduced by merely evaluating:

  (lookup-origin-revision "https://github.com/scikit-learn/scikit-learn" "1.3.2")

The crux of the problem is that ‘snapshot-branches’ used to return
either a “revision” or a “release”, but now it can also return a
“directory”:

--8<---------------cut here---------------start------------->8---
$ wget -qO- https://archive.softwareheritage.org/api/1/snapshot/c405490b80fb35cc58b34260d9ec6add8248857f |jq

    }
  },
  "next_branch": null
}
--8<---------------cut here---------------end--------------->8---

I’ll check with comrades at SWH whether this is intended.

(Note that this problem may vanish once
<https://issues.guix.gnu.org/68741> has been merged.)

Dear SWH,

In <https://issues.guix.gnu.org/69070> I stumbled upon what might be new
behavior from the /snapshot endpoint:

Current documentation mentions the ‘target_types’ query parameter, which
I could use to restrict results to “revision” and “release”:

  https://archive.softwareheritage.org/api/1/snapshot/doc/

However, that’d be the empty list of the case above.

Other snapshots seem to be missing releases and revisions as well, such
as this one:

  https://archive.softwareheritage.org/api/1/snapshot/55bda9214f962550baad25026fb3ac3ad12e3eb9/

Did anything change here?  Am I holding it wrong?  :-)

Thanks in advance,
Ludo’.

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.
