Hi,

In order to check if the SWH fallback works, time to time, I test it.  I
have a variant package of hello defined here:

   <https://github.com/zimoun/channel-example>

The source had been archived on SWH long time ago (via their Web
submission or via “guix lint -c archival”).  

Using Guix 16ef7b4, I get this:

--8<---------------cut here---------------start------------->8---
$ guix build -L /tmp/channel-example/ hi -S
The following derivation will be built:

The revision is found but then an error.  Hum?

Any clue?


All the best,

As you might have seen on #swh-devel on irc.libera.chat, this is due to
an API change on their side, which is now fixed in
fb32a38db1d3a6d9bc970e14df5be95e59a8ab02.  Tested with the usual:

  guix build -S guile-bash --check

The API change (removing “obj_id” and “obj_type” from vault replies)
might be reverted, according to what SWH folks said on IRC.

However, other incompatible changes may happen on /api/1.  For instance,
I noticed by chance that /api/1/vault/directory, which we use in
‘request-cooking’, is marked as deprecated.  I’ll update our code to the
new API soonish if nobody beats me at it, but it’s a bummer that old
code might break anytime.  :-/  (The API is officially not considered
stable.)

Thanks,
Ludo’.

No, I have not. :-)

Wait, they work for long term support and they break backward compatibility.
For instance, all the versions that "guix time-machine" is able to
reach can break because they change their API in the future.  Wow.
Do I understand well?

Cheers,
simon
