Dear,
Using Guix 04a459a, the classical:
guix build dune
guix build dune --no-grafts --check -K
return:
--8<---------------cut here---------------start------------->8---
guix build: error: derivation `/gnu/store/kg7mnb1b09n5zddgvc4hs8ira3i4jzz2-dune-1.11.3.drv' may not be deterministic: output `/gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3' differs from ‘/gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3-check’
--8<---------------cut here---------------end--------------->8---
then:
diff -r --no-dereference /gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3{,-check}
returns a large output (truncated here):

Is it expected? Does it comes from timestamp? Is it avoidable?
I have not tried (yet) with the patch [1] updating ’dune’.

Zimoun,
Thanks for the report!

Don't use ‘diff’ for this, use something like diffoscope:
$ diffoscope --exclude-directory-metadata --html dune.html $old
$new
-> https://www.tobias.gr/dune.html
I think the problem is confined to the first screenful: one header
byte differs, and then $old has an extra byte that shifts
everything to the right causing these huge diffs.
Kind regards,
T G-R

The difference seems to be bigger than a simple timestamp, but it's all
on binary files, and diffoscope is not very useful for that. Maybe file
system ordering? I'm investigating.

Is it not related to your detailed analysis:
<http://issues.guix.gnu.org/43745#51>
BTW, the update of “dune“ #43745 seems fixing the issue.
All the best,

Yes, the differences look very similar between these two issues. I've posted a bug report at https://github.com/ocaml/dune/issues/3863. Hopefully this will result in a good fix. As a workaround, building with one thread seems to be effective, but we need to change the dune-build-system for that.

Yes indeed :) nice side-effect.

Which means core-updates, right?

We don't have more than 300 dependents, so I think it should be master.
