I’m currently refactoring the picard spec file to conform to the new python
build guidelines (used pyprojectize, thanks!),
everything fine there so I thought I’d add --disable-autoupdate so as to remove
the new update
option at runtime. Picard allows for this by using --disable-update. When I try:
%pyproject_wheel -C–disable-autoupdate=None
It build fine, but doesn’t work. I’ve asked the good folks at the Picard forum
and here is the response:
I tried getting options to pass with python -m build, but without success.
Picard is using the setuptools backend, and it looks like passing arbitrary
options is currently not working there. See the discussion at Setuptools
does not pass config_settings through backend · Issue #2491 ·
pypa/setuptools · GitHub .
I would have expected something like python -m build --wheel
-C--disable-autoupdate
or maybe python -m build --wheel -C--disable-autoupdate=True should work,
but it doesn’t for now, as the parameters are not passed on.
One workaround seems to be to add a custom build backend that overrides the
relevant
parts to handle the customer build parameters as it was done for example in
Add custom
build backend to support build args by tobiasah · Pull Request #328 ·
capnproto/pycapnp · GitHub
We could also maybe check for specific environment variables or such. But
ideally the issue gets solved in setuptools itself.
Am I missing some functionality in the Fedora buildtools or is this just not
possible. Thanks for any insights.
