Hello,

So there=E2=80=99s another situation where offloading regularly hangs on
berlin.  The =E2=80=98guix offload=E2=80=99 process looks like this:

It=E2=80=99s a =E2=80=98get-bytevector-n=E2=80=99 for 8 bytes, so it looks =
like the daemon
protocol.  At that point the socket is actually dead: if I connect on
the remote machine (overdrive1.guixsd.org) I can see that there are no
other open SSH sessions.

A simple thing would be to somehow get libssh to pass POLLIN | POLLRDHUP
instead of just POLLIN.

Additionally, we could change Guile-SSH so that we can specify a timeout
when reading from a channel.

Hello,

Reported here:

  https://www.libssh.org/archive/libssh/2019-01/0000000.html

A fix has been proposed by upstream and should be committed shortly.

Turns out we can set a per-session timeout, which we already do (see
#:timeout in =E2=80=98open-ssh-session=E2=80=99 in (guix scripts offload)) =
but
=E2=80=98ssh_channel_read=E2=80=99 would ignore it and instead pass an infi=
nite timeout
to poll(2):

  https://www.libssh.org/archive/libssh/2019-01/0000001.html

This issue happens to be fixed in libssh 0.8.x, so I upgraded our libssh
package in commit a8b0556ea1e439c89dc1ba33c8864e8b9b811f08.

(That still doesn=E2=80=99t tell us why our =E2=80=98guix offload=E2=80=99 =
processes would
occasionally be stuck but at least it ensures the build farm keeps
making progress even when that happens.)

Seems the patch in the response at the URL you linked is awaiting some
feedback/review.  Is this the reason 'guix substitute' hangs for so long
when the substitute server is down? (like 1 minute or so).

The issues above are in libssh and were fixed a while ago.  =E2=80=98guix
substitute=E2=80=99 doesn=E2=80=99t use Guile-SSH/libssh, so the problem yo=
u=E2=80=99re seeing
must be something different.

What do you mean by =E2=80=9Cthe substitute server is down=E2=80=9D?  You m=
ean =E2=80=98guix
publish=E2=80=99 is not running, or the machine is unavailable altogether?

Thanks,
Ludo=E2=80=99.
