Noticed because this makes one test in the meson test suite fail:

git clone https://github.com/mesonbuild/meson
cd meson
MSYSTEM= python3 run_unittests.py -n0 test_vsenv_option

With Python 3.11.4 and empty MSYSTEM things fail:

$ PATH= MSYSTEM= /ucrt64/bin/python3.exe -c "import _sqlite3; print(_sqlite3)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: DLL load failed while importing _sqlite3: The specified module could not be found.

$ PATH= /ucrt64/bin/python3.exe -c "import _sqlite3; print(_sqlite3)"
<module '_sqlite3' from 'C:/msys64/ucrt64/lib/python3.11/lib-dynload/_sqlite3.cp311-mingw_x86_64_ucrt.pyd'>

With Python 3.10.12 both cases work:

$ PATH= MSYSTEM= /ucrt64/bin/python3.exe -c "import _sqlite3; print(_sqlite3)"
<module '_sqlite3' from 'C:\\msys64\\ucrt64\\lib\\python3.10\\lib-dynload\\_sqlite3.cp310-mingw_x86_64_ucrt.pyd'>

$ PATH= /ucrt64/bin/python3.exe -c "import _sqlite3; print(_sqlite3)"
<module '_sqlite3' from 'C:/msys64/ucrt64/lib/python3.10/lib-dynload/_sqlite3.cp310-mingw_x86_64_ucrt.pyd'>

The text was updated successfully, but these errors were encountered:

@naveen521kk do you have any ideas?

I guess related to getpath.py?

          tests: skip a test that fails with new Python 3.11 from MSYS2

28506a8

For some (atm unknown) reason mingw Python fails to load some modules
when the prefix is removed from PATH, like in this test.

Skip for now to make the test suite pass again. Once
msys2-contrib/cpython-mingw#141 is fixed
this can be reverted.

I've created a meson branch to skip the failing test, in case we update before this is fixed: https://github.com/lazka/meson/tree/msys2-python311-upgrade

edit: we did, so mesonbuild/meson#12049

This is the default behavior on upstream Python. We previously
reverted this behavior because it broke some use cases.
