gobject-introspection: rebuild against 3.13

[sil2100]

We see a FTBFS of at-spi2-core. The main reason is that gobject-introspection was built against 3.12, and the build can't work with 3.13. Rebuild it and also switch to using the py-versioned versions of packages.

Fixes: #37369

Related: #37197

thanks. please feel free to ask for clarification, or to disagree.

drop python3 and python3-dev here. they're either already covered or potentially bring the wrong thing in.

actually, i think just do py${{vars.py-version}}-build-base-dev and you'll get what you need.

[sil2100]

Ah, I need to one day sit down and just browse through all the packages available for the Python multi-versioned efforts. Forgot about -build-base-dev, convenient!

drop python3 here. melange will add the necessary depends for it. (on python-3.13-base).

I have a much worse PR in #37370 but there is one thing I was adding that is missed here. There is a binary g-ir-scanner which is not able to run because a runtime dependency on python3 did not exist.

I did some experimenting using your PR and adding python3.13 as a run time dependency but that did not resolve the issue because the shbang in g-ir-scanner only ever has python.

(20/20) Installing gobject-introspection (1.82.0-r2)
OK: 77 MiB in 34 packages
2664dae60eac:/work/packages# head -n1 /usr/bin/g-ir-scanner 
#!/usr/bin/env python3

The point being if you continue working on this please sort out getting g-ir-scanner to work. Thanks!

This package has a build-time config for the python interpreter - but even if you explicitly set it to python3.13, it will still shave the .13 off in the shebang. I don't think python-as-wrapper, would help here because it explicitly mangles the path, but I could be wrong.

I submitted this upstream to add a shebang option:
https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/510

For now, we may just need to do a sed of the shebangs in the destdir.

For now, we may just need to do a sed of the shebangs in the destdir.

we should have a pipeline like below. There are a lot of places where we do shbang rewrites and all very inconsistently.

uses: shbang/edit
with:
  # matches match whole line (^<match>$), the ^ and $ added.
  matches: ".*python3"
  new: "/usr/bin/python${{vars.py-version}}"
