Does _memimporter still exist in py2exe?

I have only recently started with py2exe, and I would like to use py2exe with MINGW64 Python3 programs (and corresponding libraries). However, the first example I tried failed to build.

After that, I found the https://www.py2exe.org/index.cgi/TroubleshootingImportErrors page, where it is noted:

Check that zipextimporter works on your system

zipextimporter is the starting component of py2exe that may cause problems. To debug it you will need _memimporter.pyd binary module. These modules can be found in binary py2exe distributions for your Python version (I unpack .exe distribution with 7Zip).

There is also a test script, but it is in Python 2 (last update of that page is 2011-01-07); so I converted it to Python 3 syntax:

import zipextimporterzipextimporter.install()import syssys.path.insert(0, "lib.zip")import _socketprint(_socket)# <module '_socket' from 'lib.zip\_socket.pyd'>print(_socket.__file__)# 'lib.zip\\_socket.pyd'print(_socket.__loader__)# <ZipExtensionImporter object 'lib.zip'># Reloading also works correctly:print(_socket is reload(_socket))# True

But when I run it, I get:

$ python3 test_zipextimporter.pyTraceback (most recent call last):  File "D:/msys64/tmp/test_zipextimporter.py", line 1, in <module>    import zipextimporter  File "D:/msys64/mingw64/lib/python3.11/site-packages/zipextimporter.py", line 51, in <module>    import _memimporterModuleNotFoundError: No module named '_memimporter'

So, as the note above says, I need a _memimporter.pyd binary module; there is no such file in the package directly:

$ pacman -Ql mingw-w64-x86_64-python-py2exe | grep _mem$

However, the note also states "These modules can be found in binary py2exe distributions for your Python version (I unpack .exe distribution with 7Zip)." Currently there are these binary files in the package:

$ pacman -Ql mingw-w64-x86_64-python-py2exe | grep '\.exe\|\.dll'mingw-w64-x86_64-python-py2exe /mingw64/lib/python3.11/site-packages/py2exe/resources.dllmingw-w64-x86_64-python-py2exe /mingw64/lib/python3.11/site-packages/py2exe/run-py311-mingw_x86_64.exemingw-w64-x86_64-python-py2exe /mingw64/lib/python3.11/site-packages/py2exe/run_ctypes_dll-py311-mingw_x86_64.dllmingw-w64-x86_64-python-py2exe /mingw64/lib/python3.11/site-packages/py2exe/run_w-py311-mingw_x86_64.exe

None of these can be listed with say unzip -l; but they can be listed with 7z l - unfortunately, I see nothing there resembling _memimporter.pyd - both .exes show this structure of files:

I've tried to compare with the vanilla py2exe download, and results are similar:

I guess this _memimporter is still a thing, because after all my test script fails with "No module named '_memimporter'"; and also there are still references in the Python code of the package:

$ grep -rI _memimporter /mingw64/lib/python3.11/site-packages/py2exe/mingw64/lib/python3.11/site-packages/py2exe/distutils_buildexe.py:##             self.excludes.append("_memimporter") # builtin in run_*.exe and run_*.dll/mingw64/lib/python3.11/site-packages/py2exe/hooks.py:# _memimporter can be excluded because it is built into the run-stub./mingw64/lib/python3.11/site-packages/py2exe/hooks.py:_memimporter

... but, I have to ask - is this _memimporter.pyd still a thing - and if so, where do I find it?
