I agree IPython is a complex package with a lot of dependencies, though the hang with IPython doesn't take much to reproduce.

So yes, lets focus on the simpler problems.

No it doesn't. But I see hangs on both Jedi and Pygments during IPython install.

If I install them individually there is no hang.

Looks like my versions appear to match yours.

Note I haven't installed the newer (test) 3.9 packages, cygcheck shows:

python39 3.9.16-1                       OK
python39-pip 24.0-1                         OK

$ python3.9 -m ensurepip --version
pip 19.2.3

$   python3.12 -m ensurepip --version
pip 24.3.1

$ python3.12 -m pip --version
pip 24.3.1 from /usr/lib/python3.12/site-packages/pip (python 3.12)


Also, the error I see with venv is that something you see as well or is it just me?

$ python3.12 -m venv /srv/pyvenvs/test312
Error: Command '['/srv/pyvenvs/test312/bin/python3.12', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

$ python3.12 -m ensurepip

Thank you for your help on this and all your work as a Cygwin maintainer.
