Yeah, I suppose this was due to the proportion being different because the overall number of lines changed. I'm not seeing 99.13% there, though. Perhaps, it processed more reports after your comment.
For me, it shows 94.94% for the entire pytest flag and 99.88% for tests/ flagged with pytest and 98.15% for yarl/+pytest.

I suppose, it's okay to raise the codecov/project/lib expectation to 98.1% (leaving that 0.05% margin for future line count changes, until we can go for 100%).

I'm going to do a RC0 release so I can run this in the CI of a few projects since typing changes are always hard to predict the impact

Hello, I think this change broke python 3.8 support:

../lib/python3.8/site-packages/yarl/_url.py:606: in URL
    def query(self) -> MultiDictProxy[str]:
E   TypeError: 'type' object is not subscriptable

If I downgrade to release 1.9.7 it works again.

You might want to update python requirements to indicate python>=3.9 is required

Would you please open an issue report, I will fix it shortly

[bdraco]

Please include the multi dict version you are using in the issue

Please include the multi dict version you are using in the issue

As far as I can see, multidict has supported that syntax for ~6 years...
But, maybe we should increase the minimum version of multidict that yarl supports.

I had to take the python 3.8 install back to multidict 4 to get it to fail. There might be a newer version that fails though as I stopped trying them once I confirmed the issue. Also even with 4 it didn’t fail on python 3.9 so I suspect the issue will go away on its own soon when we drop 3.8
