Build Python 3.13 wheels (not free-threaded) #711

edgarrmondragon · 2024-07-13T06:55:27Z

I can close this if #703 gets more attention, but I've confirmed changes here allow the wheels to be built in 3.8-3.13, and all tests are passing.

This warning is currently raised, but fixing it might be beyond the scope of this PR:

PytestUnraisableExceptionWarning: Exception ignored in PyDict_GetItem(); consider using PyDict_GetItemRef() or PyDict_GetItemWithError(): None

python/cpython#106004

Closes 3.13 support #698
Closes Doesn't install on python 3.13 #741

I think this is ready for an initial review.

Mostly followed advice from

.github/workflows/ci.yml

This missing parameter is causing a ton of warnings like this:

msgspec/_utils.py:130: DeprecationWarning: Failing to pass a value to the 'type_params' parameter of 'typing._eval_type' is deprecated, as it leads to incorrect behaviour when calling typing._eval_type on a stringified annotation that references a PEP 695 type parameter. It will be disallowed in Python 3.15.

FWIW I think this is hiding an actual error:

Python 3.13 release is scheduled for then upcoming Monday. Are there any plans to merge this PR and publish a new version?

Tishka17 · 2024-10-07T16:55:30Z

Python 3.13 is out there.

maurerle · 2024-10-11T17:19:00Z

This closes #741 and #698

I was building on debian 13 trixie which uses GCC 14, I therefore had a few more required adjustments on top of yours:

maurerle@2aa5db5

To build this locally, I used conda:

conda create -n py313 python-freethreading -c conda-forge
conda activate pyt313
git clone -b py313 [email protected]:maurerle/msgspec.git
cd msgspec
pip install .

@maurerle thanks for finding that. I'll give a read to https://py-free-threading.github.io/porting/, unless someone beats me to it and knows what's wrong here.

maurerle · 2024-10-12T07:36:08Z

When executing this on a gil build (e.g. conda create -n py313-gil python=3.13)
One gets an error if executed from the build directory:

>>> import msgspec
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    import msgspec
  File "~/github/msgspec/msgspec/__init__.py", line 1, in <module>
    from ._core import (
    ...<14 lines>...
    )
ModuleNotFoundError: No module named 'msgspec._core'

So make sure to execute this not in the build directory :)
It works fine then :)
But I don't have a clue how to solve the above segfault either.

The segfault also occurs when starting the above mentioned freethreading build with an active GIL as in
python -X gil=1 -c "import msgspec"

Keeps around the semantic meaning for when this function is added back in Python 3.14.

jcrist · 2024-10-13T19:27:25Z

Thanks for the PR (and everyone for their patience). With a new kid and recent layoff, I've been a bit busy and msgspec maintenance has languished. I really appreciate the help and patience here.

I have a few small fixups I want to land with this release, but I'd expect a release supporting Python 3.13 (not with freethreading) out in the next day or two. I'll work on adding freethreading support after getting that initial release out.

ekneg54 · 2024-10-19T18:30:15Z

Hi,

with this merged I thought that I should be able to install msgspec on python 3.13. But it turns out, that this is not the case as you could see:

I wonder if I am missing something. Could you help?

maurerle · 2024-10-19T18:40:19Z

You are missing the python3-dev dependency.
Install it using your system package manager

mj0nez · 2024-10-19T18:42:54Z

It was merged but not released or am I mistaken? An install from main should work for sure: install from vcs

ekneg54 · 2024-10-19T18:51:15Z

thank you. I wait for the release. Do you know when it is planned?

mj0nez · 2024-10-19T19:04:56Z

No, but soon I guess.
