So it seems ‘guix substitute’ picked /nar/zstd, even though
bordeaux.guix is not advertising that.

Or is it?

So it seems that bordeaux.guix did advertise zstd at some point (and
that narinfo is still in cache) but no longer does.

Chris, can you confirm?

I’ll see how to get ‘guix substitute’ to handle that gracefully.

See? zstd’s gone!  This confirms my hypothesis.

BTW, ‘guix publish’ has provisions to not compress already-compressed
files, as in the case above.  We should really share code, Chris.

Yeah, this would have been a consequence of reducing the cache size [1].

I'm not sure if this is what you have in mind regarding code sharing,
but I'll use compressed-file? from (guix utils) in the nar-herder to
avoid generating cached compressions for these kind of files in the
future.

Great, thank you.

Ideally we’d have a single ‘guix publish’ implementation, or at least
most of it would be a module shared by both ‘guix publish’ and
‘nar-herder’ because it’s tricky enough that we’d rather not have two of
them.  The (guix narinfo) module you introduced is a step in that
direction and as discussed earlier, we need to go further.

As discussed on IRC, I think nar-herder should honor the TTL it
advertises for all the URLs of the narinfo (lzip, zstd, etc.) because
that’s how ‘guix substitute’ currently interprets the TTL.

Eventually it would be nice for ‘guix substitute’ to interpret the TTL
as applying to one of the URLs (not necessarily all of them), but this
kind of change takes months if not years to be widely deployed because
users rarely (if ever) update guix-daemon.

That the exception went through despite the ‘network-error?’ guard is
fixed by 3f59fd6d114548480c719d4b8f8509bdf3e8dcca.

The reason was that the ‘&http-get-error’ condition was getting wrapped
in a ‘kind-and-args’ exception upon rethrow, as illustrated here:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (catch #t
		       (lambda () (raise-exception (condition (&message (message "boo")))))
		       (lambda args args))
$5 = (%exception #<&message message: "boo">)
scheme@(guile-user)> (with-exception-handler (lambda (e) e)
		       (lambda () (apply throw $5))
		       #:unwind? #t)
$6 = #<&compound-exception components: (#<&error> #<&irritants irritants: (#<&message message: "boo">)> #<&exception-with-kind-and-args kind: %exception args: (#<&message message: "boo">)>)>
scheme@(guile-user)> (message-condition? $6)
$7 = #f
--8<---------------cut here---------------end--------------->8---
