I'm running into some issues porting my icoextract package to

pybuild-plugin-pyproject, but it required some hacks along the way.
However, I'm not sure if I'm seeing bugs/limitations in the toolchain,
or I'm using the tools in some non-standard manner.
I've staged the changes at https://salsa.debian.org/jlu/icoextract/-/tree/debian/experimental?ref_type=heads.
(Disclaimer: I am also the upstream author)
1) The .deb package seems to leave behind
/usr/lib/python3/dist-packages/build/lib/icoextract. I can remove it
manually with an execute_after_dh_auto_install rule, but it doesn't
feel like this should be necessary. I've attached what the file list
looks like without the rm -rf rule.
This usually happens because the setuptools configuration in your
pyproject.toml fails to exclude the "build" directory, which becomes a
problem when the packaging builds for two different Python versions.
The typical fix is to change this:
[tool.setuptools.packages.find]
exclude = ["tests"]
... to this:
[tool.setuptools.packages.find]
include = ["icoextract", "icoextract.*"]
2) lintian complains about additional files in
/usr/lib/python3.14/dist-packages/icoextract-0.3.0.dist-info/. The
rest of the source files are installed to
/usr/lib/python3/dist-packages/icoextract/, which is what I expect
from previous versions currently in the archive.
This is a side-effect of 1).
3) `export PYBUILD_INSTALL_ARGS=--install-scripts=debian/tmp` doesn't
seem to do anything now. I think that might be because
--install-scripts is a setup.py specific feature, but the wiki is
still hinting at this approach for packaging programs[1][2]. In my
case, I'm fine with changing python3-icoextract to contain the library
& CLI utils, and making icoextract a meta-package instead. AFAICT most
distros did not bother to split the package at all.
If this is still a problem after fixing 1), consider just moving the
relevant files around in an execute_after_dh_auto_install rule in
debian/rules. Much easier.
