Hi,

Some packages need to ship language override files. Some packages do that
in python*-foo binaries, whereas others do it in the gir* binaries. The
problem with the former is that rdeps need to depend on the python*-foo
package rather than / in addition to the gir1.2-foo-* package. Examples:

gedit: /usr/lib/python3/dist-packages/gi/overrides/Gedit.py

gir1.2-accounts-1.0: /usr/lib/python2.7/dist-packages/gi/overrides/Accounts.py
gir1.2-accounts-1.0: /usr/lib/python3/dist-packages/gi/overrides/Accounts.py
gir1.2-dee-1.0: /usr/lib/python2.7/dist-packages/gi/overrides/Dee.py
gir1.2-gexiv2-0.10: /usr/lib/python2.7/dist-packages/gi/overrides/GExiv2.py
gir1.2-gexiv2-0.10: /usr/lib/python3/dist-packages/gi/overrides/GExiv2.py

python-blockdev: /usr/lib/python2.7/dist-packages/gi/overrides/BlockDev.py
python-gst-1.0: /usr/lib/python2.7/dist-packages/gi/overrides/Gst.py
python-gst-1.0: /usr/lib/python2.7/dist-packages/gi/overrides/GstPbutils.py
python-gst-1.0: /usr/lib/python2.7/dist-packages/gi/overrides/_gi_gst.x86_64-linux-gnu.so
python-gst-1.0-dbg: /usr/lib/python2.7/dist-packages/gi/overrides/_gi_gst.x86_64-linux-gnu_d.so
python-v-sim: /usr/lib/python2.7/dist-packages/gi/overrides/v_sim.py
python-vipscc: /usr/lib/python2.7/dist-packages/gi/overrides/Vips.py
python3-blockdev: /usr/lib/python3/dist-packages/gi/overrides/BlockDev.py

python is probably ok, as it's an app and doesn't export the typelib, it's
shipped in /usr/lib/x86_64-linux-gnu/gedit/girepository-1.0/.

As for the rest: python*-gst may be special as it builds a library, but
for the others it may be best to just ship the overrides in the gir packages.

Thoughts?

Cheers,
Emilio

But one problem of having Python (for example) overrides file in
gir1.2-* package is, that it creates unnecessary dependency on python
even for non-python rdepends.

Currently some gir1.2-* packages with Python overrides files have
intentionally missing python dependency to avoid such unnecessary
dependency and have lintian-overrides to avoid lintian error
python-package-missing-depends-on-python.
(https://lintian.debian.org/tags/python-package-missing-depends-on-python.html)

I'm not against having language overrides in gir1.2-* packages. But
when we choose to do it, it would be great if the mini policy clarify
this: If gir1.2-foo has Python overridess file, should gir1.2-foo
depend on Python? If not, is it OK to have lintian-overrides?
