[bug#74517] [PATCH 0/8] Remove gtk@4 input dependency on qtbase@5.

[Nicolas Graves via Guix-patches via]

I found that curious that building gtk@4 inherently requires qtbase@5
in the store's inputs.  Turns out it's based on a few libraries that
have optional graphical helping tools.  I've disabled them using
minimal variants.  After this patch series there are no input-only
path from gtk@4 to qtbase@5.

Nicolas Graves (8):
  gnu: Add v4l-utils-minimal.
  gnu: zbar: Split outputs.
  gnu: Add zbar-minimal.
  gnu: libde265: Remove unused qtbase-5 input.
  gnu: libde265: Update to 1.0.14.
  gnu: libdc1394: Replace v4l-utils by v4l-utils-minimal.
  gnu: gst-plugins-bad: Replace inputs with -minimal variants.
  gnu: gst-plugins-good: Replace v4l-utils by v4l-utils-minimal.

As an alternative to packaging broken outputs, perhaps we could simply
tell the build system to not build with Qt, or wholly remove it from the
inputs?

This can be rewritten using the gexp variabls #$output and #$output:gtk.

That is clever, perhaps too clever (in comparison to the simple brute
force approach of using a distinct minimal package variant built without
the extra inputs) :-).

Could be done in a separate commit; this entangles concern and makes it
easier if in the future a revert needs to be made.

Yes, but I think the output split is desirable independently of the
minimal variant (for when we won't have to carry the propagated-inputs
anymore), and thus it makes sense to keep it.  WDYT?

I could also try to package :
- one minimal version
- one gtk version in its own package, trying not to rebuild but to link
if not too complex
- not try to package a qt version (I'm not able to debug this).

I see; the previous commit neatly organized dependencies on gtk/qt in
separate outputs, and this variant ensures any reference to these output
is severed, without any rebuild.  It's a researched approach, but I'm a
bit worried about long term maintenance/correctness; I feel a classic
variant rebuilt without the problematic inputs would be both easier to
understand and maintain in the long term.

Also, same earlier comments hold about package/inherit and using
#:disallowed-reference along with an explanatory comment.

I don't understand how this resolves the issue, at a glance.  Is the
issue that some v4l-utils tools, kept in a distinct output, are referred
to in the pkg-config files, present in the main output?

A comment explaining would be beneficial, but mostly I would rather we
use the more traditional style of rebuilding the package with the
modified inputs, so that it's cleanly built as a 'qtbase-less' variant;
that should lead to less bad surprises down the road, at the expense of
a bit more computation, which we can afford.

As a variant (a package sharing the same source but using different
inputs/build flags), the package should be defined via
'package/inherit', which will honor the parent package's replacements
(grafts).

I'd explain in a comment what this variant is for (break dependency on
Qt); better yet, a #:disallowed-reference could be use along such
comment to ensure the property is preserved in time.

I agree that was sub-optimal, thank you for addressing that.  This
actually would resolve #51994 I had reported some time ago ("GTK 4
requires qtbase through various sources (gstreamer plugins)"), so you
(or the person who pushes) should add this as a git trailer:

--8<---------------cut here---------------start------------->8---
Fixes: https://issues.guix.gnu.org/51994
--8<---------------cut here---------------end--------------->8---

and close the associate bug after it's pushed.

I left some comments; I think I'd prefer a simpler rebuilt variant
solution compared to the fancier but more frail (because of more
complex) runpath hacking/trivial-build-system copying business involved
in this version.

These LGTM.

Thanks a lot for tackling this problem!

I get it, I chose that because of its lack of need to rebuild, while the
simpler rebuild variant would indeed require a rebuild (here a copy).
It's not that big of a subject here, these libraries are not super heavy
themselves so I'll change that.

I still like this solution for this reason, and I think this could be
applied for some other packages I've worked on (e.g. libreoffice is very
tricky to separate the build into steps, because some of its build
elements require the whole package, but it can be split at the end).
Agree to keep this as an exception when the alternative is really more
complex though, or when the build is very heavy (and thus making a copy
despite additional complexity makes sense).

Same comment here; it should be a list of packages; not a list of
strings, unless I've missed something.

Hi Ludovic, Nicolas,

Ludovic Courtès <ludo@gnu.org> writes:

> Maxim, could you take a look at v3 of this patch series?

Thanks for the ping.  I've looked at v3, and it looks good to me, except
for the newly added #:disallowed-references (which I suggested adding)
which should be a list of packages, not a list of strings, if I'm not
mistaken.

Also, a #:disallowed-references added directly to GTK (to ensure it
continues not pulling in qtbase) would be a nice to have, but can be
added later too; I believe adding a disallowed reference should not lead
to rebuilds?

Nicolas, would you mind sending one last v4 with the corrected
#:disallowed-references?  You can grep for examples.  After which, I
think it should be merged to the gnome-team branch (CC'ing Liliana to
make sure it makes sense at this stage).

I think the value of #:disallowed-references need to be a list of
packages, not strings.
