It seems to be related to the commits between
c7d2dd69004b020de5d86898d2497ab3c8435c37 and
1ad5209d904d471ded6cf53b4e29b64e963dea3f.

I’m trying this now as a work-around:

    ~/.config/guix/current/bin/guix pull --commit=1ad5209d904d471ded6cf53b4e29b64e963dea3f

Hi,

Here’s a reproducer that works well for me:

  guix time-machine --commit=be0ecfb1787b9e6954bf745bceeb1b9d2669d51a -- \
    pull --commit=d8feee9f18ede0d1ea4d0e4876f09a0dab770295 -p /tmp/test

Before that I was able to pull from
df05842332be80ed7f53022402b95cf711163b41 to
d8feee9f18ede0d1ea4d0e4876f09a0dab770295 just fine.

Good news, this is fixed by 50ea3135e0948a042cd3b899e970f6ade291a0c2!

As noted in the commit log, this issue stemmed from a change in
#:autoload semantics in Guile 3.0.  In 3.0, the line:

  #:autoload (gcrypt hash) (port-sha256)

means that only ‘port-sha256’ is imported.  Conversely, in 2.2 (which is
the Guile version used by the ‘compute-guix-derivation’ program above),
that #:autoload line means that all the (gcrypt hash) bindings are
imported.  That includes the ‘sha256’ bindings, which would thus prevent
matching the ‘sha256’ literal in the ‘origin-compatibility-helper’
macro.  Terrible!

Huh?  I just used #:autoload for the first time (in the native
qemu-image patch thaw way may not be using after all ...) and so I just
read the documentation.

]I am pretty sure that t]The 3.0 documentation says that "when a module
is autoloaded, all symbols become available"?

    http://git.savannah.gnu.org/cgit/guile.git/tree/doc/ref/api-modules.texi#n298

So...what's going on here?

Ah!  It’s an omission, fixed in Guile commit
723e483e7d88897f1ad654028e86a87dd040b886.

The changed was made late in the 2.9.x series, in commit
cb14fd214365e50b6b1655616ae74d0228933bbd, and later documented in
‘NEWS’.

Thanks for the heads-up!

Ludo’.
