Different behaviour of 1.0.0 wheels from pypi

Hello,

I noticed that the manylinux_2_17_x86_64.manylinux2014_x86_64 and py3-none-any pypi wheels behave differently.

Bug Report

...but I don't know specifically what the issue is 😬
I wrote a mypy plugin. It used to work correctly with mypy 0.920-0.991. Then the tests started failing in CI when 1.0.0 was released. I've easily reproduced that locally. Wanted to get to the bottom of it, so downloaded mypy source, checked out v1.0.0, installed the local package and... the tests passed.
I've only later discovered that when I use the py3-none-any wheel from pypi it also works as expected.

The plugin hooks into get_type_analyze_hook, get_method_signature_hook and get_function_signature_hook modifying instances of a specific class (joining Protocols together). I understand this is no place to seek help in my project, but I believe the issue is with these particular distributions and not on my end, since everything works correctly when using the source or the generic wheel.

Locally I'm testing everything with python 3.10.9, but I've also confirmed this is the case with 3.11.1 and it failed with 3.7.15 in CI (Github Actions).

To Reproduce

I wish I could provide a simpler example, but I'm afraid I can't. I've tried narrowing the issue down, but couldn't do it with a compiled version of mypy and the source version works beautifully 😬 .

git clone https://github.com/klausweiss/typing-protocol-intersection.git --branch mypy-1.0.0
cd typing-protocol-intersection
python -m venv venv-manylinux
source venv-manylinux/bin/activate
pip download mypy==1.0.0 --platform=manylinux_2_17_x86_64 --only-binary=:all: 
pip install *.whl
mypy --config-file tests/test-mypy.ini tests/testcases/in_generic_param_unhappy_path.py --no-incremental

Outcome is

tests/testcases/in_generic_param_unhappy_path.py:49:15: error: Argument 1 to "get_x_y_1" has incompatible type "ProtocolIntersection[HasX]"; expected "DesiredObject"  [arg-type]
tests/testcases/in_generic_param_unhappy_path.py:49:15: note: "ProtocolIntersection" is missing following "DesiredObject" protocol member:
tests/testcases/in_generic_param_unhappy_path.py:49:15: note:     y
Found 1 error in 1 file (checked 1 source file)

Expected Behavior

Outcome:

tests/testcases/in_generic_param_unhappy_path.py:49:15: error: Argument 1 to "get_x_y_1" has incompatible type "ProtocolIntersection[HasX]"; expected "DesiredObject"  [arg-type]
tests/testcases/in_generic_param_unhappy_path.py:49:15: note: "ProtocolIntersection" is missing following "DesiredObject" protocol member:
tests/testcases/in_generic_param_unhappy_path.py:49:15: note:     y
tests/testcases/in_generic_param_unhappy_path.py:50:15: error: Argument 1 to "get_x_y_2" has incompatible type "typing_protocol_intersection.types.ProtocolIntersection[HasX]"; expected "typing_protocol_intersection.types.ProtocolIntersection[HasY, HasX]"  [arg-type]
tests/testcases/in_generic_param_unhappy_path.py:50:15: note: "ProtocolIntersection" is missing following "ProtocolIntersection" protocol member:
tests/testcases/in_generic_param_unhappy_path.py:50:15: note:     y
Found 2 errors in 1 file (checked 1 source file)

You get the expected outcome when you follow the same steps as above, but downloading a py3-any-none wheel instead:

git clone https://github.com/klausweiss/typing-protocol-intersection.git --branch mypy-1.0.0
cd typing-protocol-intersection
python -m venv venv-manylinux
source venv-manylinux/bin/activate
pip download mypy==1.0.0 --platform=none --only-binary=:all: 
pip install *.whl
mypy --config-file tests/test-mypy.ini tests/testcases/in_generic_param_unhappy_path.py --no-incremental

Again, that's also the behavior I observed when cloning the mypy repo, checking out v1.0.0, and installing from a local directory.

Actual Behavior

See the To Reproduce section.

Your Environment

• Mypy version used: v1.0.0
• Mypy command-line flags: --no-incremental --config-file tests/test-mypy.ini
• Mypy configuration options from mypy.ini (and other config files):
  • contents of tests/test-mypy.ini:

    [mypy]
    plugins = ../typing_protocol_intersection/mypy_plugin.py
    check_untyped_defs = True
    disallow_any_generics = True
    disallow_any_unimported = True
    disallow_incomplete_defs = True
    disallow_subclassing_any = True
    disallow_untyped_calls = True

    warn_return_any = True
    warn_unused_configs = True
    

• Python version used: 3.10.9 but also with 3.11.1 and 3.7.15, haven't checked any others
• OS: Manjaro Linux 5.15.91, glibc version 2.36

リンクされている typing-protocol-intersection の再現手順と、その mypy-1.0.0 ブランチから始めます。manylinux および py3-none-any wheel 用に提供されている pip download コマンドと mypy コマンドを実行し、その結果をソースチェックアウトと比較します。ディストリビューション固有の挙動が説明され、報告された再現結果に予期しない差異がなくなれば完了です。
