gh-91338: Ensure test_ucnhash_capi_reset doesn't pass PYTHONHOME to _testembed.exe by neonene · Pull Request #32313 · python/cpython (original) (raw)
A minor tweak for Windows. _test_embed.exe fails to import *.pyd modules when the initialization is repeated with PYTHONHOME from python.bat.
>python.bat -m test test_embed -v

sys.path at Loop#1 has the build directory, which is replaced with f"{PYTHONHOME}/DLLs" at the next loop. The behavior looks realistically designed.
GitHub CI machines doesn't show the error, using rt.bat where PYTHONHOME is not set.
