[bug#55316] [PATCH] scripts: package: Transform before creating manifest entries.

[Josselin Poiret via Guix-patches via]

* guix/scripts/package.scm (options->installable): Add TRANSFORM
argument, to be able to directly transform the new packages before
creating their manifest entries.
(process-actions): Remove transform-entry, and step3.
---
Hello everyone,

Someone on IRC [1] reported that they couldn't run

guix install emacs-avy emacs-embark --with-branch=emacs-avy=master --with-branch=emacs-embark=master

without guix complaining about conflicting entries of emacs-avy and
the propagated one from emacs-embark, even in a profile without either
of them.  The issue was that package transformations were applied to
the contents of the generated manifest entries, but weren't applied to
any of their dependencies.  To solve this, I figured it would be simpler
to just apply the transformation from the start, only creating the manifest
entries after they have been applied.  Also, the
default `package->manifest-entry` preserves transformations properties by default,
so this doesn't lose any info either.

With this patch applied, the above command works as expected for me.

Best,

Josselin Poiret

As discussed on IRC, could you make sure transformation properties are
preserved in the manifest?

I only see one test that explicitly checks that,
"transaction-upgrade-entry, transformation options preserved" in
tests/packages.scm, and then there’s "options->transformation +
package->manifest-entry" in tests/transformations.scm.

Also, could you add a test that reproduces the problem being fixed?

Thanks!

Hello Ludo,

Thanks for your review.  As mentioned on IRC, those tests don't test
process-actions, which is where the logic resides.  I added a test to
guix-package.sh that follows the original issue instead, note although
that between yesterday and today, emacs-consult has changed enough to
not compile anymore with `--with-branch=emacs-consult=main` (branch
rename notwithstanding).

Best,
Josselin
