Hi,

From 9d795fb, I get on machine A,

$ guix time-machine --commit=a7b20226b2 -- build hello

Last, on machine B, the time-machine just works.  Maybe it is related to
NVMe and something like [1].

Well, I still do not understand why the time-machine raises an error
when the store have the necessary item.  Any idea?

This looks like something different, but it’s very weird.  The unhelpful
‘match-error’ seems to occur early on:

--8<---------------cut here---------------start------------->8---
$ head -1942 ~/.cache/guix/inferiors/wulvgnewx2av6dvgkq6adku4kzmlva75l2gukndywh7wvzenkmoa/share/guile/site/3.0/guix/ui.scm | tail -12

      (with-fluids ((%file-port-name-canonicalization #f))
        (dynamic-wind
          (const #f)
          (lambda ()
            (apply command-main args))
          (lambda ()
            ;; Abuse 'exit-hook' (which is normally meant to be used by the
            ;; REPL) to run things like profiling hooks upon completion.
            (run-hook exit-hook)))))))

(define (run-guix . args)
--8<---------------cut here---------------end--------------->8---

Does “guix time-machine --commit=a7b20226b2 -- help” work for you?

Can you fiddle at the REPL and try to see more precisely what’s failing?

  guix time-machine --commit=a7b20226b2 -- repl -q

Thanks,
Ludo’.

It works on all of my machine except my newest one…

…and what is different between all my machines and the newest one?

One thing is CPU.  It reminds me the unrelated OpenBLAS failure [1].
Well, the situation is:

* Fail

        i7-10700K  (Comet Lake)

* Build

        i7-6500U   (Skylake)        <-- Ludo ?
        5218       (Cascade Lake)

Re,

Maybe the issue is coming from the old Guile 3.0.2 of 2020 not
supporting some recent CPU…  Well, I do not know.

Any idea for debugging?  I already have tried to remove the potential
bugs between the chair and the keyboard. :-)

Is it possible that it comes from Guile 3.0.2 on a recent CPU?

Bah, I have not idea.  Does it come from

--8<---------------cut here---------------start------------->8---
(define (map/accumulate-builds store proc lst)
  "Apply PROC over each element of LST, accumulating 'build-things' calls and
coalescing them into a single call."
  (define result

             (proc obj)))
         lst))
[...]
--8<---------------cut here---------------end--------------->8---

where line 1337 is the one with ’(map (lambda (obj)’?


Well, it is weird, isn’t?  I am lacking some magical trick to
investigate more.  Any ideas?

I don’t think it has anything to do with that.  Seems more like a
problem in our code that would only manifest under special
circumstances—we just need to find out what makes them special.  :-)

That looks like <https://issues.guix.gnu.org/53594>.  I don’t have a
good hypothesis for that yet, but I’m guessing it’s stateful: the bug
manifests if some things are missing from the store.

Could you try:

  guix time-machine --commit=a7b20226b2 -- build hello --no-grafts

If it works, does the same command without ‘--no-grafts’ work
afterwards?

Another data point.  Recompile a7b20226b2 using recent Guile.

It does not work when using no-grafts.  However, a big ’guix gc’ makes
it work.  It is really weird.  Note that the previous pre-inst-env is
done before GC.

Well, I have not been enough attentive to correctly save the problematic
part.  Now, I am unable to reproduce. )-:


It is hard to know what had been initially substituted and what had been
locally recompiled.  I mean, today and after GC, it looks like,

all these derivations are locally built and I do not know what happened
a couple of days ago.  If these had been substituted and if the
substitutes had something incompatible with my hardware for whatever
reason, then weird behaviour.  Hum, too many if. :-)
