The 'wrap' phase of 'python-build-system' adds native-inputs to
PYTHONPATH of the wrapped programs. This causes unnecessary runtime
dependencies and may create problems when cross-compiling.

Given that all python dependencies are now supposed to be propagated,
perhaps we can simply remove the wrap phase? It only touches PYTHONPATH.

We cannot simply remove it: it is meant for packages that provide
standalone programs, such as ‘certbot’. For these, it automatically
wraps bin/* and we don’t even have to have propagated inputs, which is
pretty cool.

However, you are right that native inputs shouldn’t be there. Probably
we need to add some filtering in the ‘wrap’ phase?

While looking at the beets package definition with fresh eyes, I realize
that it will surely break once this change is made. So it will make a
good test case for this improvement :)

I'm working on fixing this bug. I have modified
guix/build/python-build-system.scm for the same. In particular, I have
added #:use-module (guix packages) because I need the functions
`package-name' and `package-transitive-target-inputs'. But, when I try
building any python-build-system package with something like
"./pre-inst-env guix build scons", I get a ("no code for module" (guix
packages)) error. What am I missing?

Full backtrace follows:

“Build-side” modules, which typically live in (guix build …), should not
depend on “host-side” modules such as (guix packages). That’s because
if we did that, we’d effectively end up importing all of Guix on the
build side, but then we’d also have to serialize data structures such as
packages to pass them from one side to the other. (I hope this makes
sense to you, but if it doesn’t maybe the intro of
shed some light.)

So in short, we cannot use ‘package-name’ and
‘package-transitive-target-inputs’ in this module.

(Time passes…)

I wasn’t sure how to fix this bug myself so I gave it a try and ended up
with the patch below, but I haven’t tested in detail. (You’ll notice
(guix build-system python) is hard to work with because it doesn’t use
gexps yet.)

How does it look?

Thanks,
Ludo’.

It makes some sense, but I'll read up more.

I tried your patch. But native-inputs are still there in the wrapped
PYTHONPATH. I printed out the results from various steps from the wrap
phase. They are as follows:

`build-time-inputs' is

Somehow, the paths in `build-time-inputs' are not the same as those in
`path'. Notice the different hashes. Hence `remove' does not succeed in
filtering them out.

This is to ensure that no references to any native input are retained in
the output. (Think of it as an assertion that is checked at the end of
the build.)

Hi! Are you asking me? I haven't worked on this in a very long
time. But I'll give it another shot now and get back to you.

The two lists are the same if `guix build' is invoked with the
`--no-grafts' flag. I don't understand grafts very well and am not sure
how that can be fixed. Any ideas?

See different output below with and without the `--no-grafts' flag.

This fixes a longstanding issue. The fix is made trivial by the changes made
in #60847 adding cross-compilation support for the pyproject build system.
Additionally, it's based on #60868, which touches the wrap phase to use
wrap-script instead of wrap-program.

I think there’s no need to delay+thunk things since we’re using them
right away. How about:

(define native-input-directories
(match native-inputs
…))

(let ((var `("GUIX_PYTHONPATH" prefix
,(remove (lambda (x) … native-input-directories …) …))))
…)

?

(Same for ‘%guile’ above, but I don’t see it in ‘master’; maybe that’s
from another branch?)

Thanks,
Ludo’.

It's a (small) optimization, that was intended to delay things until
they are really needed that was already used for %bash (now %guile) in
the wrap phase of (guix build python-build-system).

The idea is to delay the evaluation of native-input-directories or the
lookup for guile in the inputs until it's really necessary. For
example, the computations are avoided when there are no "bin" or "sbin"
sub-directories in the outputs.

Yes, the change build on both #60847 (Enable cross-compilation for the
pyproject-build-system) and #60868 (Use wrap-script instead of
wrap-program), which should be applied first. %guile appears in #60868,
and changes that make the above easy (native-inputs always appearing as
native-inputs, even for native builds) are from #60847.

I'm still on my first cup of coffee...

If a python input is in inputs and in native-inputs would it be included
in the wrapper or not? At first glance I'd say no. Does the search path
do deduplication? If it doesn't then it'd work to only remove the first
instance matching from native-input-dirs.

It wouldn't be included with the current simple logic, which simply
remove any native input from the items of GUIX_PYTHONPATH. Good catch!
I'll send a v2 with the refined check.

- Rework wrap phase to avoid removing inputs found in both native-inputs and

- Enclose wrap computations in an 'unless' form and streamline

LGTM!

I still don’t see what branch this snippet is on, what am I missing?

[PATCH v3 0/1] build-system/pyproject: Do not wrap native-inputs.
(address . 25235@debbugs.gnu.org)
20230123133434.1852-1-maxim.cournoyer@gmail.com
This fixes a longstanding issue. The fix is made trivial by the changes made
in #60847 adding cross-compilation support for the pyproject build system.
Additionally, it's based on #60868, which touches the wrap phase to use
wrap-script instead of wrap-program.

Changes in v3:
- Rebase

Changes in v2:
- Add missing copyright line
- Rework wrap phase to avoid removing inputs found in both native-inputs and inputs
- Enclose wrap computations in an 'unless' form and streamline

It's based on https://issues.guix.gnu.org/60868,itself based on
https://issues.guix.gnu.org/60847. I've tried to express this
relationship by marking the dependent changes blocked by the submissions
they are based on.

I've just rebased the 3 submissions and added you in CC; hopefully that
helps!

(address . 25235@debbugs.gnu.org)
874jbheuvh.fsf@ngraves.fr
Hi Lars, Ricardo,

I'm advancing with my patch series, which I can submit soon. I was
curious about why this 25235 patch isn't in python-team branch yet since
it's also a very welcome change to the pyproject-build-system.

Cheers,

Nicolas

I believe this change is based on #60847, which Ludo objected to
