Control: retitle -1 pandas: FTBFS on warnings from pytest 8.4
Control: fixed -1 2.3.1-1
The actual error isn't that, but the 120 subcases of
pandas/tests/groupby/test_raises.py::test_groupby_raises_category_on_category
that fail with
E AssertionError: Caused unexpected warning(s):
[('PytestWarning', PytestWarning("matching against an empty string will
*always* pass. If you want to check for an empty message you need to
pass '^$'. If you don't want to match you should pass `None` or leave
out the parameter."),

pandas/_testing/_warnings.py:203: AssertionError
As this is a warning about lack of test coverage, not about actual
results, the current pandas is fine to use.
debci says the trigger is pytest 8.3 -> 8.4. Given that this appears to
be a normal (non-urgent) upgrade that is also blocked by several other
issues, and pandas 2.3 (in experimental) fixes it while causing only a
few other issues (see #1111280), I intend to work on getting pandas 2.3
into unstable instead of trying to fix this in 2.2.
If pandas does need to be rebuilt for an urgent reason (e.g. a security
update), disabling the affected test should work.
