Hi,
Hi Miroslav,
If it's in tree then it's supported, in the sense that we accept issues
for them and will endeavour to resolve reports.
Longer term, Python team will aim to move closer to tracking upstreams
(CPython) definition of supported, which is essentially latest
major.minor plus one minor version back (security and bugfixes).
we are using Python 3.7 for hosted applications. New application
requires py-uvicorn so I built it in poudriere as usual. No errors. But
after installation on target machine uvicorn does not work spiting
following traceback:
Traceback (most recent call last):
File "/usr/local/bin/uvicorn", line 10, in <module>
from importlib.metadata import distribution
ModuleNotFoundError: No module named 'importlib.metadata'
I couldn't see why/how uvicorn is using or calling importlib_metadata
(it imports importlib, as the initial traceback line shows) in a cursory
source review [1] . Something is transforming the import importlib call
or falling back to importlib_metadata automatically for Python < 3.8,
but I didn't investigate or isolate what.
Are all ports completely up to date with respect to latest versions in
the tree?

OK, py-importlib-metadata is probably missing so I tried to build it in
poudriere but it failed in configure stage with the following error:

This is https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256872
Workaround, manually install py-toml or enable TOML option in
setuptools_scm port options (which is disabled, causing this issue).
Reach out in #freebsd-python on Libera IRC if you need further help or
have questions.
