Package: src:python-psutil
Version: 7.2.2-1
Severity: serious
Tags: ftbfs forky sid patch
Dear maintainer:
During a rebuild of all packages in unstable, this package failed to build.
The failures do not happen always, but the failure rate is higher on single-cpu
systems, so I recommend GRUB_CMDLINE_LINUX="nr_cpus=1" to reproduce. If this
is not enough, I can offer a VM to reproduce, as always.
I've put several build logs here for reference:
https://people.debian.org/~sanvila/build-logs/202610/
Note that the failing tests are not always the same, but there are four or them
which happen often enough:
FAILED tests/test_process.py::TestProcess::test_long_cmdline
FAILED tests/test_unicode.py::TestFSAPIsWithInvalidPath::test_proc_name
FAILED tests/test_unicode.py::TestFSAPIsWithInvalidPath::test_proc_cmdline
FAILED tests/test_unicode.py::TestFSAPIsWithInvalidPath::test_proc_exe
I see there is already a bunch of tests being skipped in debian/rules
for several reasons, so I propose that we do the same for those four tests,
as in the attached patch (where NNNNNNN is to be replaced by the actual bug
number).
Thanks.
