CCing the python list.

Simple answer: Build-Depend on pybuild-plugin-pyproject. And then you 
may need to change some things.

But... we should make this the default. Thanks for the reminder. This 
has been on my TODO list for a while. But I forget to look at it early 
in a release cycle.

Here's a starting point:
https://salsa.debian.org/python-team/tools/dh-python/-/merge_requests/77

I'm test-building 50 packages that build-depend on dh-python but not 
pybuild-plugin-pyproject here:
https://debusine.debian.net/debian/r-stefanor-dh-python/workflow/?page=1

It looks like I'm going to need to do a complete rebuild (5300 odd 
packages) and file a *lot* of bugs.

What are common problems?

I tried to check stuff there but couldn't find a relevant failure.

Sorry, I started testing some other things in there too, so it's a bit 
of a mess. The test source was: dh-python_7.20251225.post2.dsc

So, failures like:
https://debusine.debian.net/debian/r-stefanor-dh-python/artifact/2931844/
https://debusine.debian.net/debian/r-stefanor-dh-python/artifact/2932234/
(due to directory layout differences when building)

And changes in behaviour like going from a private module to public:
https://debusine.debian.net/debian/r-stefanor-dh-python/artifact/2932950/
rules: https://salsa.debian.org/debian/termtosvg/-/blob/debian/latest/debian/rules?ref_type=heads

We're going to have to rebuild everything and look for diffs.

There was also https://bugs.debian.org/1124064

I imagine there's a whole class of bugs like that.

I wonder if we should make some design changes to improve these.

We could change the layout that the pyproject plugin uses. e.g. separate 
test and install extractions of the wheels.

They would come with their own downstream breakage, of course, but it'd 
be for the better.

Separate test and install extractions does seem like a good idea.  We 
are absolutely drowning in RC bugs right now though; is there any chance 
we could get over the 3.14-supported hump first?
