Anyone experiencing kodi segfaults with python 3.12?

graysky · 2024-05-12 18:32:53

Has anyone else noticed kodi ending in segfaults since the python 3.12 update? For example, the youtube plugin triggers them upon exiting kodi (standalone-service from the AUR), but other plugins are also trigger them. Link to upstream bug report I created.

As the coredump is from a system service it lacks debug symbols. Upstream might benefit from having a back trace with them.

Have you looked at https://github.com/python/cpython/issue … 2088613250?

Yes, kodi is crashing always on exit.

Did you try the cpython fix?

If it helps python 3.12.3 with https://github.com/python/cpython/pull/118618 applied:

Thanks loqs, I build python-3.12.3-1 with that PR and it seems to have fixed the crashing.

loqs · 2024-05-13 19:32:18

Hopefully it will be merged for upstream 3.12.4. I do not know if Arch will take it before that as from my understanding it involves an ABI change and I doubt Arch will want to rebuild all the python packages with a C interface for this fix.

graysky · 2024-05-16 16:48:27

I think you're right. For now, I just built it patched for my own use. Thanks again.

Thanks loqs - I posted there

ozooha · 2024-07-13 19:00:02

@graysky Are you still using the patched version of python 3.12.3-1.1?
I was experiencing this and applying this patch helped.

graysky · 2024-07-13 19:47:49

Yes, but I build against 3.12.4-1

ozooha · 2024-07-14 17:18:08

Can you share that package or educate me on how to apply that patch for every python update?
I'm using that python-3.12.3-1.1-x86_64.pkg.tar.zst from the Google Drive link above and set the IgnorPkg into pacman.conf

You can build it yourself or I can share mine with you. Here is the patch you need which has been modified from the PR to remove the section that hits the abi file. Just clone our python package and apply the following patch to your PKGBUILD:

@graysky
I tried your patch, but it ran tests which took hours before I had to kill the process (twice).
So can you share your final pkg of the python with the patch.

Wild Penguin · 2024-07-30 13:11:40

Tests seem to hang here, too at:

test_in_thread (test.test__xxsubinterpreters.CreateTests.test_in_thread) ...

, indefinitely. There is no CPU usage (I've been waiting for an hour, seems like it is not going to finish).

Of course one could disable tests, I suppose. I'm not sure yet how, I've not built python before (possibly --disable-test-modules would do the trick), but obviously doing that is not recommended and might have huge caveats.

Sorry, I did not see your reply until now. I uploaded the package and sig file here.

ozooha · 2024-08-01 00:18:07

Thank you.

jfk · 2024-08-02 14:14:24

I built Kodi with the python 3.12.4-1 shared above but it's still freezing on my system.

@ozooha is it working for you?

ozooha · 2024-08-11 17:57:10

@jfk Sorry I saw this now.
Yes, it works for me - no segfaults when exiting kodi with that patched version of python.
I did not build kodi with it, but instead replaced my python with that patched version from @greysky.

graysky · 2024-08-24 14:18:09

*sigh* the issue still exists with python-3.12.5.

I uploaded the patched package for this version and sig file here if anyone wants it.

Thanks again.
