2.0.1 fails to build with Python 3.11.0a2

[hegjon]

Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with a pre-releases of Python 3.11.

Updating bundled versioneer should fix this.

I believe 032073e2bdd4634d6d55fb94a6f41bb5e5b15252 should fix this, but I do not have available 3.11 to test. Could you check if it does fix the issue ?

[hugovk]

Yes, or at least I can install fine with Python 3.11:

note

Versioneer 0.21 is compatible with Python 3.6+, so you may need to drop EOL 3.4-3.5 (3.6 is also EOL):

cycle	latest	release	eol
3.10	3.10.1	2021-10-04	2026-10-04
3.9	3.9.9	2020-10-05	2025-10-05
3.8	3.8.12	2019-10-14	2024-10-14
3.7	3.7.12	2018-06-27	2023-06-27
3.6	3.6.15	2016-12-23	2021-12-23
3.5	3.5.10	2015-09-30	2020-09-13
3.4	3.4.10	2014-03-16	2019-03-18

But 3.4-3.5 are little used. Here's the pip installs for libusb1 from PyPI for December 2021:

category	percent	downloads
3.6	67.43%	146,358
3.8	11.49%	24,936
3.7	8.70%	18,877
3.9	4.81%	10,430
null	4.34%	9,414
2.7	2.38%	5,164
3.10	0.80%	1,738
3.5	0.05%	98
3.4	0.01%	18
3.11	0.00%	4
Total		217,037

Date range: 2021-12-01 - 2021-12-31

[vpelletier]

Thanks for the test and heads-up about version usage & compatibility. I did not know pypi was still collecting stats ever since these were removed from the webpage.

I just started working on releasing the next version, but found that libusb 1.0.25 was just released, and that my unit tests are making it unhappy (segfault when freeing a transfer). I reported the issue to libusb.

[vpelletier]

I fixed the test issues with 1.0.25, and released python-libusb1 3.0.0 (major bump because of the drop of <py3.6).

I believe this resolves this bug report, thanks !
