3.10, 3.11, 3.12: Windows fails to build, test_ssl NOT_ENOUGH_DATA failure on macOS, test_socket fails on Fedora Stable (Linux 7.1) #153598
Description
There are multiple issues on 3.10, 3.11 and 3.12 branches:
- Windows fails to build on 3.10:
PCbuild/find_python.batdownloads a corruptednuget.exe. The nuget URL should be updated. Fix: commit 106eb53 should be backported. - test_socket: UDP Lite tests fail on AMD64 Fedora Stable, the machine was rebooted 3 days ago to upgrade to Linux kernel from 7.0 and 7.1, but Linux 7.1 removes UDP Lite support. Fix: commit 3cfc249 should be backported.
- test_ssl fails with
NOT_ENOUGH_DATAon macOS. Fix commit acfe02f should be backported.
For test_socket (UDP Lite), I prepared fixes:
- 3.12: [3.12] gh-149776: Skip UDP Lite tests if it's not supported (#149777) #153592
- 3.11: [3.11] gh-149776: Skip UDP Lite tests if it's not supported (#149777) #153593
- 3.10: [3.10] gh-149776: Skip UDP Lite tests if it's not supported (#149777) #153594 -- I included the nuget URL change to fix the Windows CI jobs.
The test_socket issue is not blocked the GitHub Action, only buildbots are failing.
I'm not sure in which order we should fix these issues.
Maybe we should start from test_ssl fixes:
- 3.11: [3.11] gh-100372: Use BIO_eof to detect EOF for SSL_FILETYPE_ASN1 (GH-100373) #153311
- 3.10: [3.10] gh-100372: Use BIO_eof to detect EOF for SSL_FILETYPE_ASN1 (GH-100373) #153312
The Windows and macOS issues block my test_socket PRs since the Windows and macOS jobs fail.

Oh, test_ssl also fails with
NOT_ENOUGH_DATAon the "AMD64 Fedora Stable 3.11" buildbot (OpenSSL 3.5.7 9 Jun 2026): https://buildbot.python.org/#/builders/942/builds/1341vstinner commentedon Jul 11, 2026
AMD64 Fedora Stable LTO + PGO:

test_socket also started to fail on "PPC64LE Fedora Stable 3.12"; "aarch64 Fedora Stable 3.12" and "s390x Fedora Stable 3.12" buildbots: the Linux kernel was also upgraded to 7.1 there.

The "AMD64 Windows11 Non-Debug 3.10" buildbot is also affected by the nuget issue: https://buildbot.python.org/#/builders/918/builds/546

I've opened backport PRs for the #153438 nuget URL fix for 3.12-3.10:

The problem is that test_ssl fails on your 3.10 and 3.11 PRs. We should combine the nuget and the test_ssl to fix both issues at the same time.

@pablogsal: As the release manager, how do you want to unblock the situation? Are you ok to fix these issues (nuget, test_socket, test_ssl)?
pablogsal commentedon Aug 7, 2026
Yes I think I would prefer to fix these issues unless you really advice against.
This weekend I will do a pass to all 3.10/3.11 PRs
