Bug#1000716: python3-pony: fails on Python 3.10 with "ModuleNotFoundError: No module named 'parser'"

[Louis-Philippe Véronneau]

Package: python3-pony
Version: 0.7.14-1
Severity: serious
User: debian...@lists.debian.org
Usertags: python3.10

Hello,

It seems the current version of ponyorm is broken on python3.10. If you
look closely at the logs from the latest DebCI run [1], it outputs
(without failing........):

> Sorry, but pony 0.7.14 requires Python of one of the following
> versions: 2.7, 3.3-3.9. You have version 3.10.0+

Actually running pony on 3.10 outputs something like:

======================================================================
ERROR: tests (unittest.loader._FailedTest)
----------------------------------------------------------------------
ImportError: Failed to import test module: tests
Traceback (most recent call last):

ModuleNotFoundError: No module named 'parser'

This is because the parser module has been removed in Python 3.10 in
favor of ast [2].

I'll suggest upstream to fail their testsuite when ran on Python 3.10.

reassign 1000716 src:ponyorm
rename 1000716 ponyorm: FTBFS on Python 3.10
thanks

Oh well, it seems it does sys.exit(1) when trying to build the package,
just not when running the testsuite by itself...

I: pybuild base:237: python3.10 setup.py clean

Sorry, but pony 0.7.14 requires Python of one of the following versions:
2.7, 3.3-3.9. You have version 3.10.0+

E: pybuild pybuild:354: clean: plugin distutils failed with: exit
code=1: python3.10 setup.py clean
