This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle. Changing version to 36. The test is:
def test_element_cyclic_gc_none(self):
# test if cyclic reference can crash etree
Element = self.etree.Element
getrefcount = sys.getrefcount
# must disable tracing as it could change the refcounts
trace_func = sys.gettrace()
try:
sys.settrace(None)
gc.collect()
count = getrefcount(None)
l = [Element('name'), Element('name')]
l.append(l)
del l
gc.collect()
count = getrefcount(None) - count
self.assertEqual(count, 0) <--- this assert fails, count is -1
finally:
sys.settrace(trace_func)
Tomáš, this is from a build with Cython 3 alpha? Does that same test fail on Python 3.10 with Cython 3 alpha?
(In reply to Miro Hrončok from comment #2) > Tomáš, this is from a build with Cython 3 alpha? Yes > Does that same test fail on Python 3.10 with Cython 3 alpha? No, test and also whole build passed. Hence I opened this bugzilla, because it seemed that the problem is in Python 3.11 and not in Cython 3 used for this build. Closing this in bulk as it built with Python 3.11. If this needs to remain open for a followup, feel free to reopen, I won't close in bulk again. |

You can follow these instructions to test locally in mock if your package builds with Python 3.11: https://copr.fedorainfracloud.org/coprs/g/python/python3.11/ Let us know here if you have any questions. Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
