Hi,

I=E2=80=99m using guix on a multi-machine setup with a single remote guix-d=
aemon that
can be reached via SSH. Thus GUIX_DAEMON_SOCKET=3Dssh://master.<domain> on =
the
compute nodes. Running `guix pull` on master works fine (the variable is not
set here), but it does not on a compute node. Instead it fails with this er=
ror:

Obviously the socket on that compute machine is not working, because it=E2=
=80=99s on an
NFS share /var/guix belonging to master. But why is the socket considered in
the first place?

This is a limitation in =E2=80=98build-aux/build-self.scm=E2=80=99:

      ;; Use the port beneath the current store as the stdin of BUILD.  This
      ;; way, we know 'open-pipe*' will not close it on 'exec'.  If PORT is
      ;; not a file port (e.g., it's an SSH channel), then the subprocess's
      ;; stdin will actually be /dev/null.
      (let* ((pipe   (with-input-from-port port
                       (lambda ()
                          ;; =E2=80=A6
                                      (if (file-port? port)  ;<- here
                                          (number->string

                                          "none"))))))

We could work around it by letting the =E2=80=98GUIX_DAEMON_SOCKET=E2=80=99=
 environment
variable through, along these lines:

It=E2=80=99s a bit hacky though, and won=E2=80=99t work with old Guix revis=
ions anyway.

However, for your use case, you could perhaps simply pull on one machine
and use =E2=80=98guix copy=E2=80=99 to send Guix elsewhere?  Or even explic=
itly run
=E2=80=98guix pull=E2=80=99 on each node?

Thanks,
Ludo=E2=80=99.

Hi Ludo,

I don=E2=80=99t understand what=E2=80=99s going on there unfortunately. Is =
there a high-level
explanation somewhere in the manual?

Nope, that does not seem to be enough. After pulling on master doing the sa=
me
on a node (with a patched guix) yields:

---snip---
ice-9/eval.scm:293:34: Throw to key `srfi-34' with args `(#<condition &stor=
e-connection-error [file: "ssh://master.<domain>" errno: 95] 7f0f325f77b0>)=
'.
---snap---

Any ideas?

That means `guix time-machine` could not go back beyond a commit that fixes=
 the
issue, correct? Not a concern for me.

> However, for your use case, you could perhaps simply pull on one machine
> and use =E2=80=98guix copy=E2=80=99 to send Guix elsewhere?
The store is the same on all machines, since /gnu/store, /var/guix and /home
are all shared via NFS. As far as I understand the manual `guix copy` would=
 be
useful for store to store transfers on different machines only.

Lars

Sounds like this ssh URI is not valid on the nodes, is that right?

Correct.

Right.  So perhaps I don=E2=80=99t quite understand the use case.  What abo=

simply pulling from one of these machines, if everything is shared over
NFS?

Hi,

I would consider it valid, since `ssh master.<domain>` and `guix build
<package>` both work just fine from the nodes. It=E2=80=99s just `guix pull=
`, which is
causing issues.

> Right.  So perhaps I don=E2=80=99t quite understand the use case.  What a=
bout

Sure, that=E2=80=99s an option, but anyone who tries will get a strange err=
or message.
And it breaks the appeal of having a remote guix daemon in the first place,
that is being able to run `guix <whatever>` on any machine I log into. If t=
hat
is not the case (i.e. not for `guix pull`) it would be more consistent to a=
sk
users to SSH into a different machine every time they interact with guix. D=
oes
that explain my use case?

Oh it may be that we would also need to let =E2=80=98HOME=E2=80=99 through,=
 so that
~/.ssh/config is found, for example.  That could have undesirable side
effects that are best avoided, though (e.g., ~/.cache/guile would become
visible.)

I agree that the error message is sub-optimal.  Not sure how to improve
on it (how can =E2=80=98build-self.scm=E2=80=99 know that it=E2=80=99s fail=
ing because of
that?).

 Does
> that explain my use case?

Instead of:

  GUIX_DAEMON_SOCKET=3Dssh://host guix pull

You could run:

  ssh host guix pull

In fact, the former would probably not work because =E2=80=98guix pull=E2=
=80=99 modifies
the local /var/guix/profiles, not the one on the host that runs the
daemon.

So maybe the problem is that =E2=80=98GUIX_DAEMON_SOCKET=3Dssh://=E2=80=99 =
isn=E2=80=99t quite as
powerful as you thought.  :-)  It=E2=80=99s really just a way to talk to a =
remote
daemon, but =E2=80=98guix pull=E2=80=99, =E2=80=98guix package=E2=80=99, et=
c. also need to access
/var/guix/profiles.

Thanks,
Ludo=E2=80=99.

shouldn=E2=80=99t be a problem since ~/.ssh/config does not exist for that =
user and
known hosts are globally declared in /etc/ssh/ssh_known_hosts (strace indic=
ates
that guile-ssh/libssh reads that file).

If I stop the daemon and `guix pull` it just says =E2=80=9Cguix pull: error=
: failed to
connect to `/var/guix/daemon-socket/socket': Connection refused=E2=80=9D. S=

Sure, that=E2=80=99s the only workaround I can think of right now.

Yes, /var/guix is shared via NFS too. Otherwise roaming between machines
wouldn=E2=80=99t work at all.

It is, it=E2=80=99s just a bug we have to fix :) Can I help you debug this =
somehow,
i.e. figure out where exactly the error message is coming from?

Cheers,
Lars

Well, I think you=E2=80=99re really asking for a new feature; we need more =
than
just talk to a remote daemon.

Updating profiles like =E2=80=98guix package=E2=80=99 and =E2=80=98guix pul=
l=E2=80=99 do involve two
things:

  1. building the profile=E2=80=94this is done by talking to the daemon;

  2. modifying things in /var/guix/profiles & co.

GUIX_DAEMON_SOCKET addresses #1 but not #2.

For #2, we would need to do something like Jakub did in (guix scripts
system reconfigure), where the effectul bits can be transparently
evaluated either locally or remotely.

But really, that=E2=80=99d be a brand new feature, so I=E2=80=99m marking i=
t as a
wishlist if you don=E2=80=99t mind.  :-)

Thanks,
Ludo=E2=80=99.
