Guixfriends,
Errors like the one below are omnipresent. It's a problem.
Expecting an ever-increasing (16k+?) number of requests to finish
flawlessly or aborting a very long (20+ minutes here) process is
doomed.
We don't seem to have a plan forward (I include myself!). Looking
at other package managers, a blunt ‘retry a finite number of
times’ seems common. Guix's ‘pretend that "transient" is a magic
powerword’ approach less so.
What do people think? Does the heavy pipelining complicate
matters?

I sometimes see similar failures with `guix weather`.
To clarify, do you also see them when substituting? Or just when
checking for substitutes?

Hi Tobias,

If I read correctly, the issue comes from (guix scripts substitutes)
in 'fetch-narinfos':
--8<---------------cut here---------------start------------->8---
(call-with-connection-error-handling
uri
(lambda ()
(http-multiple-get uri
handle-narinfo-response '()
requests
#:open-connection
open-connection
#:verify-certificate? #f))))))
--8<---------------cut here---------------end--------------->8---
where 'requests' can be really large (all the missing information from
local cache).
Instead of processing the list in one go, we could imagine split it
into several chunks, say X, and so process only X requests by X
requests.
WDYT?
Cheers,
simon

My bad, it is already the case where X=1000 in (guix http-client).
Well, the error / retry seems poorly handled in 'http-multiple-get'.

Hmm isn’t it a regression?
First, in (guix scripts substitute) there’s a ‘with-networking’ macro to
nicely present networking errors; perhaps we’re missing it here?
Second, is it a genuine bug? Do you see the same thing from (guix
scripts substitute)?
Thanks,
Ludo’.

I do not know if it is related, the bug#47055 seems “similar”:
