[issue29778] _Py_CheckPython3 uses uninitialized dllpath when embedder sets module path with Py_SetPath

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

_Py_CheckPython3() tries to load "python3.dll" from two directories:

* first one based on _Py_dll_path
* second one based on Py_GetPrefix()

I understand that LoadLibraryExW() must not be attempted if _Py_dll_path is empty, or if Py_GetPrefix() is empty. Am I right?
