------------------------------------------------------------------------
Thanks for the invitation. I would like to briefly summarize the results
of my previous communication with Stefano and the current status of my work.
Here are the repositories I have been working on. I have completed the
build and testing of python3.14t and python3t. An experimental
repository is also under my account:
https://salsa.debian.org/ben0i0d/python3t
https://salsa.debian.org/ben0i0d/python3t-defaults
In my previous work, I enabled |nogil| and the |t| flag to ensure that
python3t is completely isolated from the existing Python line. That is,
python3t/3.14t follows the “B” technical route. I isolated their
|dist-packages|. (However, note that since I haven’t adapted pip
packages yet, the current venv does not work properly, though manual pip
installation works fine.)
When I communicated with Stefano via email, he agreed with the idea of
using a suffix and nogil, but suggested two corrections:
1.
We cannot split out a separate python3t source package. The builds
must produce two parallel interpreters from the existing CPython
team packages (of course, they are isolated, including |/usr/lib|,
i.e., the standard library is isolated).
2.
|dist-packages| should not be isolated. This way, we only need to
focus on the porting, and if issues arise, venv can be used as a
transition.
I agree with this view, and this is what I am currently doing—choosing
option (a).
Regarding GIL vs. nogil, pure Python modules are usually not a problem,
e.g., pip. The challenge lies in Python packages with C extensions.
From my perspective, under option (a), the main issue only occurs when
mixing GIL and nogil. Perhaps we should first introduce the nogil
interpreter into Debian as a base, like Fedora, which could also bring
nogil support to Ubuntu 26.04.
As for adapting modules for nogil, I don’t have a good solution yet.
This problem will need to be discussed by the community, and I have not
conducted tests or developed feasible approaches for mixed usage so far.
Ideally, I plan to complete option (a) within two weeks, i.e., finish
the rules modifications and submit them.
At that time, I will carry out this part of the investigation.
