I think it has been fixed in a new upstream version, but that needs to
be checked.
Confirmed fixed in experimental (but *not* in unstable).
Please note that we are not yet ready to upgrade pygobject to its
latest upstream versions
Still true.
if the python3.14 transition is to happen any time soon, it is
likely to be necessary to backport the fixes for test regressions
I tried backporting the obvious fix for expected refcounts in tests
(0972c8b49040c08416648eca5ec9aac7a340666f), but this is not sufficient.
Two tests still fail with 3.14.
One is in tests/test_generictreemodel.py, which is testing pygobject 2
compatibility code that was deleted in the current upstream release (so
there will be no upstream fix to backport for this):
______________________ TestReferences.test_iteration_refs ______________________
self = <tests.test_generictreemodel.TestReferences testMethod=test_iteration_refs>
def test_iteration_refs(self):
...
for node in nodes:
if hasattr(sys, "getrefcount"):
self.assertEqual(sys.getrefcount(node), 5)
E AssertionError: 4 != 5
tests/test_generictreemodel.py:258: AssertionError
The other is that in tests/test_properties.py, a different value
is observed for the *GLib* refcount:
_____________ TestCPropsAccessor.test_held_object_ref_count_setter _____________
self = <tests.test_properties.TestCPropsAccessor testMethod=test_held_object_ref_count_setter>
def test_held_object_ref_count_setter(self):
...
self.assertEqual(held.__grefcount__, 2)
E AssertionError: 3 != 2
