ResourceWarning: subprocess is still running

[JulienPalard]

Using ooo-dev-tools 0.47.18 (also on 0.47.17 and I don't remember for previous ones) I'm getting a ResourceWarning about un unkilled subprocess:

I don't know how to reproduce this. Do your have more information?

BTW: I am working from Ubuntu 24.04

[Amourspirit]

Here is the script I am running:

import logging

from ooodev.loader.inst.options import Options as LoOptions
from ooodev.loader.lo import Lo
from pathlib import Path
import tempfile

def b():
    options = LoOptions(log_level=logging.DEBUG)
    with tempfile.TemporaryDirectory() as tmpdirname:
        tmpdir = Path(tmpdirname)
        with Lo.Loader(
            Lo.ConnectSocket(
                headless=True,
                extended_args=[
                    f"-env:UserInstallation={tmpdir.as_uri()}/user_profile",
                    f"-env:UNO_SHARED_PACKAGES_CACHE={tmpdir.as_uri()}/shared_packages_cache",
                ],
            ),
            opt=options,
        ) as loader:
            pass

b()

The env args just tells LibreOffice to not load any user or shared extensions by setting their paths to a temp directory.

On the command Line I run:

PYTHONTRACEMALLOC=20 python repro.py

Entire Results are:

Hmm... I noticed Warning: failed to launch javaldx - java may not function correctly in our output. I wonder if this is related?

[Amourspirit]

The next release has extra steps in place when closing. Most likely this will be resolved.

[JulienPalard]

Forgot to say there's an export PYTHONDEVMODE=y in my bashrc, this enables cpython to show this kind of warnings, maybe that's just what's missing?

sry

Warning: failed to launch javaldx - java may not function correctly

Seens this too, but I have no idea what this is :D Tried $ apt search javaldx, found nothing (I'm running Debian here).

I have found the default version of Debian to be a bit problematic. When I tried to install APSO or LibrePythonista (the only two I tried) on a default installation of Debian they would not install. I notiecd the default Debian did not have LibreOffice Base installed. Also when I checked in LibreOffice Settings there was no Java installed.

I tried so many ways to install java on Debian for LibreOffice and had no luck. I figured the failed installs of APSO and Librepyhthonista in Debian were due to missing Java. I could not fix it so I installed a Flatpak version of LibreOffice and then it worked fine.

Version 0.47.19 has been released to day. I now monitors the subprocess that starts LibreOffice and shuts it down when the main thread stops.
