It looks as though ‘set-build-options’ was not passing through correctly
serialized data.

So, could you add a bunch of ‘pk’ in ‘set-build-options’ in store.scm,
as well as in the corresponding code in nix-daemon.cc (under
‘wopSetOptions’, in particular), to see whether something gets munged on
the way?

TIA,

Alternately, could you run something like:

  sudo strace -f -p $(pidof guix-daemon) -o daemon.log
  guix build emacs --no-substitutes

then kill strace once ‘guix build’ has completed, and post daemon.log
(compressed)?

Thanks,
Ludo’.

I haven’t seen the bug for a while.  Should I run the above commands
anyway?

Could you check whether it’s still there?  Run ‘guix build emacs
--no-substitutes’ (for instance), and see if it uses substitutes.

If the bug is still there, yes.  :-)

Thanks,

Another strace log that could help:

  strace -o client.log guile -c \
    '(use-modules (guix))
     (set-build-options (open-connection) #:use-substitutes? #f)'

TIA,

I can’t reproduce the bug.

So you do see a difference between ‘guix build emacs’ and
‘guix build emacs --no-substitutes’, right?

Well, I suppose that’s good news, then.

Closing it.  Please reopen if it shows up again.
