Segmentation fault with uno 24.2.5 ooo-dev-tools 0.47.7 using Python 3.12.4

[JulienPalard]

Hello!

I'm on Debian trixie running:

$ apt-cache policy python3 python3-uno
python3:
  Installed: 3.12.4-1
  Candidate: 3.12.4-1
  Version table:
 *** 3.12.4-1 500
        500 http://ftp.fr.debian.org/debian trixie/main amd64 Packages
        100 /var/lib/dpkg/status
python3-uno:
  Installed: 4:24.2.5-1
  Candidate: 4:24.2.5-1
  Version table:

        500 http://ftp.fr.debian.org/debian trixie/main amd64 Packages
        100 /var/lib/dpkg/status

I'm using a venv built from the system Python (3.12.4) with system packages (so ooo-dev-tools can see system Uno), and I'm installing ooo-dev-tools in the venv:

$ python3 -m venv .venv --system-site-packages
$ source .venv/bin/activate
$ pip install ooo-dev-tools
[...]
Successfully installed ooo-dev-tools-0.47.7 ooouno-2.1.2 types-uno-script-0.1.1 types-unopy-1.2.3 typing-extensions-4.12.2

Then when doing some imports I'm getting a segfault:

I have not tested Python 3.12 just yet. I am not certain that is the issue; However I noticed that the issue starts with:

...data_type/generic_size_pos.py", line 7 

Which is:

T = TypeVar(name="T", bound=Union[int, float])

I know python 3.12 made some changes to the type system but I don't know yet if these are breaking changes.

I have limited time to test this right now, I am hoping I can get to testing this in the next few days. If you have anything to add I welcome it.

[Amourspirit]

This is looking like it a python 3.12 specefic error.
TypeVar with bad arguments segfault/misbehavior #118814

I will see if I can find a workaround for this.

[Amourspirit]

I just published ooo-dev-tools 0.47.8 This should work as a workaround.

[JulienPalard]

Thanks for the work @Amourspirit !

I just tried 0.47.8 but no luck, I'm now getting:

Fatal Python error: Segmentation fault

[Amourspirit]

Thanks for the feedback.
I am hoping to get more into this in the next day or two.

[Amourspirit]

OK, I have made more changes to correct this issue.
Version 0.47.9 is published hopfully works arround the python issue.

If you installed OooDev as an extension then please run the extension manager an update.

[JulienPalard]

Yes, it works, thank you very much for the fix!

[Amourspirit]

Excellent.
