Description Fedora Release Engineering 2020-02-06 15:37:26 UTC
python36 failed to build from source in Fedora rawhide/f32

https://koji.fedoraproject.org/koji/taskinfo?taskID=41257510


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_32_Mass_Rebuild
Please fix python36 at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
python36 will be orphaned. Before branching of Fedora 33,
python36 will be retired, if it still fails to build.

This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.

Comment 5 Miro Hrončok 2020-02-13 13:42:00 UTC
AArch64 is bz1797052, but other architectures hang: armv7hl, x86_64, s390x

> AArch64 is bz1797052, but other architectures hang: armv7hl, x86_64, s390x

armv7hl, x86_64, s390x builds all stopped while running test_faulthandler.

Example: "0:04:04 load avg: 6.59 [125/406] test_faulthandler"

It's likely the same bug than bz#1799090: GCC miscompiles faulthandler._stack_overflow().

https://bugs.python.org/issue38965

And it has been fixed in master:

"bpo-38965: Fix faulthandler._stack_overflow() on GCC 10 (GH-17467)"
https://github.com/python/cpython/commit/8b787964e0a647caa0558b7c29ae501470d727d9

I proposed https://src.fedoraproject.org/rpms/python36/pull-request/39 to backport the fix (and also backport another fix which might bite us if we don't fix it).

Comment 7 Miro Hrončok 2020-02-13 22:50:34 UTC
Running the build in f33 and f32. Should be fine. Thanks Victor!
