bug#27386: offloading documentation and env

[-- Attachment #1: Type: text/plain, Size: 597 bytes --]

Hi,

I am setting up local offloading systems and I just ran
into the same issue like I did every time in the last year:

with guile in the remote 'user' PATH the guile test works *locally*.
Through ssh, the 'env' output is different than local. I'm now trying
to fix this the same way 'scp' is fixed which is by including the
application in the system profile.

This part is implicit in the documentation and not explained, I think
we should be more clear about this.

GUILE_LOAD_PATH just started appearing in the env when I installed guile modules.

Where is the mistake?

It's probably not related, but the master (GuixSD running from git) assumes that
the 'machines.scm' should be in /usr/local/etc/guix/  where also the generated files
from guix archive --generate ended up. I changed nothing in the past, my guix is
configured the 'normal' way with localstatedir=/var

And this is from master running an offloading test as it is right now.
Both ends have GuixSD.

This means that you need to make sure that the target machine has (guix)
in its load path.

The test is to run something like:

  $ ssh localhost env |grep GUILE_
  GUILE_LOAD_COMPILED_PATH=/home/ludo/.guix-profile/lib/guile/2.2/site-ccache:/home/ludo/.guix-profile/share/guile/site/2.2:/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2
  GUILE_LOAD_PATH=/home/ludo/.guix-profile/share/guile/site/2.2:/run/current-system/profile/share/guile/site/2.2

and you should see /run/current-system/profile/share/guile/site/2.2.  If
not, you’ll have to add it somehow.

(It’s unfortunate that setting up offloading remains error-prone, but
that’s a different story!).

I assume that you have read the rest of my messages and not just skipped
through them. I thought my messages were clear that (guix) is in the
loadpath, but only *locally* on the machine, not when connecting to it
via ssh. It can be in my users loadpath, but the ssh environment is
different. Comparable to how you only get scp when you put
openssh into the global (packages) and this is also mentioned nowhere.

In other words: What you get in the loadpath when you are a local user,
logged in, differs from what you get in the loadpath when you want to
get the loadpath directly from an command run through ssh connection.

So I'm guessing here: the not so obvious yet very obvious solution is to
put guix into the global (packages)?
Where global means the canonical /etc/config.scm

Right, this is why I suggested testing that *with a non-interactive
connection*, as in:

  ssh HOST env | grep GUILE

On GuixSD, Guix is always in the global profile.

This is issued from computer A (abyayala) to computer B (shadownet).

user@abyayala ~$ ssh shadownet env |grep GUILE_
GUILE_LOAD_COMPILED_PATH=/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/lib/guile/2.2/site-ccache:/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/share/guile/site/2.2
GUILE_LOAD_PATH=/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/share/guile/site/2.2

I would have to put some ssh private keys on there or
configure sshd in a different way to issue this locally
on computer B.

The problem here is that
/run/current-system/profile/share/guile/site/2.2, which is where the
Guix modules are on GuixSD as I wrote above, is missing from the search
path.

The session started when you run “ssh shadownet env” does not spawn a
login shell; thus ~/.profile and similar are *not* sourced.  I’m using
Bash, so on my accounts, I have this in .bashrc (‘.bashrc’ is for
non-login shells):

--8<---------------cut here---------------start------------->8---
if [ -n "$SSH_CLIENT" -a -z "`type -P cat`" ]
then
    # We are being invoked from a non-interactive SSH session
    # (as in "ssh host command") but 'cat' cannot be found
    # in $PATH.  Source /etc/profile so we get $PATH and other
    # essential variables.
    source /etc/profile
fi
--8<---------------cut here---------------end--------------->8---

That way, “ssh HOST COMMAND” effectively gets the same environment as a
login shell.

If you’re using a different shell, then make sure its startup file does
something similar.

HTH!

I use the same on this computer, but at the end of it I source some
files, among them ~/.guix-profile/etc/profile

I would guess that sourcing ~/.guix-profile/etc/profile gets into
the way and that moving this to .bash_profile could fix the issue.

What do you think?

~/.guix-profile/etc/profile won't add /run/current-system/… to the
search path.  You really need to source /etc/profile, which in turn will
source ~/.guix-profile/etc/profile (on GuixSD).

I think the method as described never really worked.

When I do as you (and the manual) suggested, I no longer
have any results for ssh host env | grep "GUILE_".

When I extend it like this it works. I include the full
paste to show that previously I had the sourcing of /etc/profile
in it:

user@shadownet ~$ cat .bashrc
# Bash initialization for interactive non-login shells and
# for remote shells (info "(bash) Bash Startup Files").

# Export 'SHELL' to child processes.  Programs such as 'screen'
# honor it and otherwise use /bin/sh.
export SHELL

if [ -n "$SSH_CLIENT" -a -z "`type -P cat`" ]
then
    # We are being invoked from a non-interactive SSH session
    # (as in "ssh host command") but 'cat' cannot be found
    # in $PATH.  Source /etc/profile so we get $PATH and other
    # essential variables.
    source /etc/profile
fi

# Adjust the prompt depending on whether we're in 'guix environment'.
if [ -n "$GUIX_ENVIRONMENT" ]
then
    PS1='\u@\h \w [env]\$ '
else
    PS1='\u@\h \w\$ '
fi
source ~/.guix-profile/etc/profile
alias ls='ls -p --color'
alias ll='ls -l'
GUILE_LOAD_COMPILED_PATH="${GUILE_LOAD_COMPILED_PATH}:/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2"
GUILE_LOAD_PATH="${GUILE_LOAD_PATH}:/run/current-system/profile/share/guile/site/2.2"


I suggest that we fix the offloading documentation.
If questions are asked (I'm not the first) there are obviously problems
with how it is written.
If no one else takes on this, I will.

The difference compared to /etc/skel/.bashrc is the last two lines,
right?

On my GuixSD installation they’re not needed because /etc/profile
sources /run/current-system/profile/etc/profile, which already defines
these two variables.

But maybe your global profile is slightly different from mine, which
would explain this.  FWIW I have:

--8<---------------cut here---------------start------------->8---
$ guix package -I gui -p /run/current-system/profile
guix	0.13.0-2.de9d8f0	out	/gnu/store/js4ml3w20ysh4znp9wl0da0ljji4kisl-guix-0.13.0-2.de9d8f0
guile	2.2.2	out	/gnu/store/5zx29y44nrqj0s8h3jlvlj82k8hj4dxs-guile-2.2.2
--8<---------------cut here---------------end--------------->8---

Anyway, if you have ideas on how to improve the doc, they’re welcome.

Thanks for your feedback!

Yes. And that I source ~/.guix-profile/etc/profile before those lines.

Well this file is the same on both systems involved:

  export `cat /etc/environment | cut -d= -f1`
fi

And does /run/current-system/profile/etc/profile define GUILE_LOAD_PATH?

Hi,

I'm trying to setup offloading too.  Just for the report I had an issue
after setting up `%load-path` for guile with `.bashrc` snippet.  It
seems that also required call `guix build` with `--substitute-urls=HOST`
because without it I get `acquired build slot` loop like in
https://lists.gnu.org/archive/html/guix-devel/2015-05/msg00035.html

Actually not always works.  Still have an issue with loop.  Client waits
for `/var/guix/offload/magnolia.local/0` but `/var/guix/offload` is
missing on build machine.

Ah, stupid me, `/var/guix/offload/magnolia.local/0` is on client.

ls -1R /var/guix/offload
/var/guix/offload:
machine-choice.lock
magnolia.local
magnolia.local.slots.lock

/var/guix/offload/magnolia.local:
0

When that happens, could you check how many ‘guix offload’ processes are
running?

Also, are you sure that the build machine is eligible for offloading
(matching system type, normalized load is below 2.0, etc.)?

Thanks,
Ludo’.

Yes, machine is totally free for load.

Hmm could it be that ‘machine-load’ in (guix scripts offload) always
returns +inf.0, for instance because it fails to run “cat /proc/loadavg”
on the remote machine?  (If it succeeded we would see the message “load
on machine XYZ is N”.)

  https://git.savannah.gnu.org/cgit/guix.git/tree/guix/scripts/offload.scm#n393

What does “ssh USER@magnolia.local -i KEY cat /proc/loadavg” return,
where USER and KEY are those specified in your machines.scm file?

HTH,
Ludo’.

Yes, you can make a checkout of Guix, add ‘pk’ calls in (guix scripts
offload) (see below), and run the daemon from there:

  ./pre-inst-env guix-daemon --build-users-group=guixbuild

‘pk’ is a function that prints its argument and returns it, so you could
do:

Excellent, glad that you found out.  I reworded and pushed as
dde1e152ce42a06fe2998f3da8acb1addfd296fc.

I’m closing this bug now, because it’s been a long discussion about
various issues rather than an actual “bug report”.

Oleg & ng0, please open a new bug report if you find a problem with
offloading.  Note that the subject should clearly specify a problem
(“guix foo fails with bar”, “Offloading fails when X and Y”) or an
expectation (“Offloading documentation should describe X”, “guix foo
should not override bar”).  The current title does not pass this test.
:-)

TIA,
Ludo’.

So I'm trying to set up the same offloading and followed the
documentation and seem to have resulted in the same issue as ng0.

So guixsd.santanas.co.za is my build system VM.
Laptop, is a guixsd system I want to not compile code, and rather offload.

root@laptop ~# ssh admin@guixsd.santanas.co.za env |grep GUILE_

Returns nothing.

However, an interactive session has the correct environment variables.
So I suppose one could set this via the .zshenv or .bash_profile .

Though I'm wondering what others do? Secondly, should the official docs
be updated?

root@guixsd ~# su - admin
admin@guixsd ~$ env|grep GUILE_
GUILE_LOAD_COMPILED_PATH=/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2
GUILE_LOAD_PATH=/run/current-system/profile/share/guile/site/2.2
admin@guixsd ~$

I'm wondering if for others, by default does ssh a-guixsd-system env
|grep GUILE_ return something?

If so, why on my system, and ng0 is it not set.

Right.  On GuixSD, the default .bash_profile sources .bashrc, and the
default .bashrc has this:

--8<---------------cut here---------------start------------->8---
if [ -n "$SSH_CLIENT" -a -z "`type -P cat`" ]
then
    # We are being invoked from a non-interactive SSH session
    # (as in "ssh host command") but 'cat' cannot be found
    # in $PATH.  Source /etc/profile so we get $PATH and other
    # essential variables.
    source /etc/profile
fi
--8<---------------cut here---------------end--------------->8---

I suggest you do something similar.

HTH!

On build nodes I added the following variable definitions to
/etc/environment:

  GUILE_LOAD_PATH=/run/current-system/profile/share/guile/site/2.2
  GUILE_LOAD_COMPILED_PATH=/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2

You need to make sure that the guile process used by guile SSH is
restarted.

Thanks Ludo.

Though, I do have the default .bashrc and .bash_profile in place and
yet it's not working, by default.

  admin@guixsd ~$ diff .bash_profile /etc/skel/.bash_profile
  admin@guixsd ~$ diff .bashrc /etc/skel/.bashrc
  25a26
  > alias grep='grep --color'
  admin@guixsd ~$

So I'm assuming this doesn't work by default for all?
Unless it's because I configured the users shell to zsh, I doubt.
Because, when switching it back to bash it still doesn't work. And the
skel files are correctly in place.

It does have your above suggestion in place:

  admin@guixsd ~$ cat .bash_profile
  # Honor per-interactive-shell startup file
  if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
  admin@guixsd ~$ cat .bashrc
  # Bash initialization for interactive non-login shells and
  # for remote shells (info "(bash) Bash Startup Files").

  # Export 'SHELL' to child processes.  Programs such as 'screen'
  # honor it and otherwise use /bin/sh.
  export SHELL

  if [ -n "$SSH_CLIENT" -a -z "`type -P cat`" ]
  then
      # We are being invoked from a non-interactive SSH session
      # (as in "ssh host command") but 'cat' cannot be found
      # in $PATH.  Source /etc/profile so we get $PATH and other
      # essential variables.
      source /etc/profile
  fi

Thanks Ricardo.

So if you do this on build systems, I assume it's kinda a requirement of
sort that should go into the document?

I prefer your suggestion over my local editing of the bash/zsh files.
