The package python-gevent doesn't build on i686-linux, the following

Ran 48 tests in 1.238s
I have created a simple standalone script based on this test case:
import os, tempfile, gevent
fd, path = tempfile.mkstemp('.test')
os.close(fd)
hub = gevent.get_hub()
watcher = hub.loop.stat(path, interval=-1)
hub.loop.update_now()
gevent.spawn_later(0.5, os.unlink, path)
hub.wait(watcher)
print(watcher.attr)
print(watcher.prev)
After adding a (delete 'check) to python-gevent's arguments, we observe
the following:
% ./pre-inst-env guix environment --ad-hoc python python-gevent -- python3 ~/tmp/gevent-test.py
None
os.stat_result(st_mode=33152, st_ino=44162375, st_dev=2052, st_nlink=1, st_uid=1000, st_gid=1000, st_size=0, st_atime=1595787602, st_mtime=1595787602, st_ctime=1595787602)
% ./pre-inst-env guix environment --system=i686-linux --ad-hoc python python-gevent -- python3 ~/tmp/gevent-test.py
os.stat_result(st_mode=1000, st_ino=0, st_dev=189675956338688000, st_nlink=1000, st_uid=0, st_gid=0, st_size=6853855360088801280, st_atime=1595787555, st_mtime=0, st_ctime=-2)
os.stat_result(st_mode=33152, st_ino=2052, st_dev=2052, st_nlink=1, st_uid=1000, st_gid=1000, st_size=17592186044416, st_atime=1595787555, st_mtime=1595787555, st_ctime=0)
Namely, the i686 variant returns entirely bogus values.
I have tried reproducing this in a Guix-less environment in a Docker
container based on the i386/debian:bullseye image, but I haven't had any
luck.

Just a follow-up to mention that this still occurs when building with
--system=i686-linux, even with the recent python-gevent update to
20.9.0.

Finally disabled the test in 692c2ad327.
Closing.
Thanks for the report!

Are we sure this is the appropriate course of action? It sounds like the
test is exposing a bug in our packaging that might affect users of
python-gevent. It might be better to have the package build than not, of
course, but still we might want to investigate why the test fails.

Kuba

The issue was reported and closed upstream many versions ago. I'm
positive python-gevent works fine in Guix. It's just the test_unlink
test that fails for unknown reasons on i686. I wouldn't loose sleep on
it.
Thanks,
Maxim
