Description Fedora Release Engineering 2025-01-22 21:36:59 UTC 
python-pexpect failed to build from source in Fedora rawhide/f42

https://koji.fedoraproject.org/koji/taskinfo?taskID=128086738


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_42_Mass_Rebuild
Please fix python-pexpect 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,
python-pexpect will be orphaned. Before branching of Fedora 43,
python-pexpect will be retired, if it still fails to build.

Comment 4 Aoife Moloney 2025-02-26 13:43:34 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.
Comment 5 Ben Beasley 2025-06-19 17:41:18 UTC 
The problem here is that the package FTBFS on ppc64le and s390x only (as shown in https://koji.fedoraproject.org/koji/taskinfo?taskID=134147966, a scratch build where I forced the package to build on all architectures), because the package is “too slow” on those architectures, so we get:

> FAILED tests/test_performance.py::PerformanceTestCase::test_100000 - pexpect.exceptions.TIMEOUT: Timeout exceeded.

I recommend just ignoring tests/test_performance.py entirely: these tests help catch serious performance regressions upstream, but gating downstream builds on particular benchmark results doesn’t make sense across diverse hardware. I opened https://src.fedoraproject.org/rpms/python-pexpect/pull-request/14 to implement this suggestion.
