[BUG] Kodi crashing when switching from an add-on to another #6266

pretoriano80 · 2022-02-25T15:12:06Z

Describe the bug

Kodi is crashing when switching from an addo-on to another, in this case it's either Netflix plugin or Tubed.
I only tested with these plug-ins because it's easy to reproduce (100% trigger rate)

To Reproduce

Steps to reproduce the behavior:

Open Netflix (or Tubed) addon
Navigate to any category (no need to play any video)
Go back and open Tubed (or Netflix if you used Tubed in the first step) addon
Navigate to a category and open it, this should trigger a crash and Kodi will restart

Note: Sometimes it may crash already at step 3.
Note 2: If you fail to reproduce on first try, just try again and it will certainly crash.

Informations

LE Version: LE11 master ae5c471
Hardware Platform: RPi4 8GB - SSD as main drive
Clean install, only Netflix and Tubed addons were installed

Log file

http://ix.io/3QHR

Additional context

~~ An important thing i noticed is that i can't reproduce the bug if only one of the addons is installed, meaning that if only Netflix is installed, then it won't cause any crash, same thing if only Tubed addon is installed. ~~

It seem that even after uninstalling Tubed addon,Netflix is still crashing if you leave Netflix ,open another addon and then go back to Netflix.

I have no clue if this is a bug caused by LibreELEC or some other Kodi related component.
I did some research and couldn't find any similar bug reports for Netflix addon, Tubed, Inputstream Adaptive or Input Stream Helper.

I'm having issues after python update.
Trying to downgrade to 3.8.12 and check.

pretoriano80 · 2022-02-26T15:48:13Z

@rootcoder yes, it appears to be an issue with the new python version, but it doesn't seem to affect everyone and i couldn't find any report on Kodi forums or GitHub.
I know that we are talking about alpha versions, so bleeding age software, but it's odd that nobody reported this yet, so it hard to say if only libreelec is affected.

heitbaum · 2022-02-26T15:57:51Z

Please have a look at; Originally posted by @Maven85 in xbmc/xbmc#20853 (comment) and https://forum.libreelec.tv/core/search-result/129687/?highlight=Python

going to close these 2 issues as known issues - upstream addons. If there is a specific LE bug that needs to be fixed. Please reopen. But will need to know the detail and addon. Feedback via the forum would be great too.

pretoriano80 · 2022-02-26T16:46:11Z

Ok, i did found those comments you linked, but in my case it's the Netflix addon and none of the addons mentioned there are installed on my system.

I pinged CastagnaIT on Kodi forums about it, maybe he's aware of this issue.
It does seem that other addons are affected, not only the ones mentioned in the your links.

In the meantime on the production drive i switched back to an older nigthly that i had around and will keep another testing drive for further development on the matter.

HiassofT · 2022-02-26T17:27:05Z

I suspect it might be caused by this python bug which doesn't seem to be fully fixed (python issue is still open):
https://bugs.python.org/issue46070

heitbaum · 2022-02-26T21:56:46Z

@pretoriano80 thanks for the additional info - reopened

pretoriano80 · 2022-02-27T14:26:57Z

@heitbaum and @HiassofT i went further with the testing and i can reproduce the same crashing pattern with the latest Kodi nightly on my Android device (smartphone) , so definitely not a LibreELEC bug and not limited to LibreELEC.

However, i think that you guys have a much better way to communicate with the Kodi team directly and i'm certain that it will be solved at some point.

P. S. Maybe it's also a good thing to keep this bug report open, so if other LibreELEC users encounter this problem, will not open duplicate bug reports.

HiassofT · 2022-02-27T16:06:45Z

@pretoriano80 please create a kodi issue about the Android crash

pretoriano80 · 2022-02-27T17:30:11Z

Done, here it is - > xbmc/xbmc#21045

pretoriano80 · 2022-03-11T05:12:40Z

I suspect it might be caused by this python bug which doesn't seem to be fully fixed (python issue is still open): https://bugs.python.org/issue46070

I applied the patch provided in that bug report but it seems that the issue is still there.
I only applied it to LibreELEC so maybe patching is also required on Kodi's side, but i have to admit that i didn't looked further into it because this python thing is a bit overwhelming for me. :)
Probably there's more than only the patch i tested, but python's bug tracking is a bit confusing for me (to say at least).

However, over the weekend i will have some more time for testing, so if you guys have more hints about this issue i will gladly test them.

heitbaum · 2022-03-11T07:56:18Z

Is this the patch you tried?

python/cpython@52937c2

pretoriano80 · 2022-03-11T13:07:24Z

Is this the patch you tried?

python/cpython@52937c2

Nope,i've tested the patch from here --> https://bugs.python.org/issue46070
It seems that the patch from your link it's already merged in 3.9.10.

WallyCZ · 2022-03-22T00:26:55Z

I have built python asi debug and got something more from stacktrace:

I checked and all the patches in https://bugs.python.org/issue46070, including python/cpython@52937c2, are included in python 3.9.10, which is now in LibreElec nightly builds. Which still crashes to me.

Also in this bug issue 46070, there are multiple issues:

asyncio intilialisation : bug.py crashes on python 3.8 while our bug seems python 3.9 and up, and it is fixed in python 3.9.10 by bpo-46070: Fix asyncio initialisation guard (GH-30423)
GC race triggered by _sre module exception (only with python 3.9, not python 3.10) : win_py399_crash_reproducer.py seems to be windows only. I tried to run this test sixty times under odroid-c2 LE 11 chewitt (python 3.9.11) no crash. Also fixed in python 3.9.10 bpo-46070 : _PyGC_Fini() untracks objects (https://github.com/python/cpython/pull/30577[)

Any patches to debug by printing the interpreter of the obj are pending but no more fix is left in this 46070 report. Though I admit our issue might be related to the objects shared between interpreters, we will have to add to the issue for it to go further.

My own issue is Kodi crashes when trying to play a second video, using Jellyfin add-on which could be close to this one.
I also can reproduce with the latest kodi nightly on android.
The backtrace in the log ends up in libpython3.9.so.1.0 with a corrupted stack (previous frame identical to this frame).

pretoriano80 · 2022-03-22T16:58:25Z

@WallyCZ the log is from a crash caused by the issue i presented heee, when switching from an add-on to another?

@prahal apart from the issue you have with jellyfin, did you also tried to reproduce the issue from this bug report?
Yes, i also checked all those patches and are indeed merged, so probably the log from WallyCZ is more relevant at this point.

Unfortunately, for a proper bug report to python devs, an easy way to reproduce the issue must be provided which in our case it is not (install kodi, addons, etc).
Probably this bug will become more relevant if it's not fixed until Kodi 20 betas or RCs are released.

prahal · 2022-03-22T17:13:04Z

@pretoriano80 yes but I do not have netflix. I reproduced with jellyfin your use case. I go in jellyfin addon, open a menu then go to another addon namely Dailymotion, then back in jellyfin: crash.

About WallyCZ log, I am trying to reproduce. Rebuilding LibreElec with DEBUG=Python3,kodi . His crash report gave me hope that a test case could be build.

pretoriano80 · 2022-03-22T17:37:13Z

@prahal great, i also managed to reproduce it without Netflix, so definitely there's more about this bug, not limited to only a few addons.
Yes, if we manage to provide some accurate logs, then probably Kodi devs will take it more seriously,especially because we are talking about a bug triggered by 3rd party addons annd sometimes Kodi team ignore these reports.

prahal · 2022-03-23T15:43:24Z

@pretoriano80 you should reproduce with a debug build : "DEBUG=Python3,kodi" added to "make release".
My attempt with debug on was of a proper backtrace.
python 3.9.11 https://paste.kodi.tv/zebiyopoge.kodi
python 3.10.3 https://paste.kodi.tv/oricadudah.kodi
So this issue is one that is not already fixed in python 3.10.3

pretoriano80 · 2022-03-23T16:31:46Z

Yes, i already have the debug build, will test it soon.

pretoriano80 · 2022-03-23T18:30:52Z

Ok,so i managed to get more crash logs from LE11 debug build.

YouTube crashing --> kodi_crashlog_youtube.log
This is from a clean build,no other addons were installed and YouTube crashed on first try,no addon switching required.
Netflix crashing --> kodi_crashlog_netflix.log
This was also on clean install with only Netflix installed.
To make sure that Netflix wasn't crashing without the addon switch combo,i used this steps: Open Netflix -> Exit Netflix -> Return to Netflix -> Exit Netflix -> Open Libreelec Configuration addon -> Exit -> Open Netflix (kodi crashed)

Note: It seems that other addons i've tested (eg. Tubed) aren't crashing if YouTube or Netflix addons are not in the mix (aka disabled or not installed), but they do crash with the "addon switch combo" and YT or Netflix involved.
I still have to figure out how all these are related ,but i thought it's better to share my complete testing experience.

prahal · 2022-03-24T08:37:33Z

we have the same traces (Thread 1, python 3.9 one of mine). My first attempt at a fix was to check python 3.10 changes not backported to 3.9 but I found out that 3.10 was also broken.
I believe it is time to ask python devs to ask them for help in building a smaller test case (from our traces maybe they can hint).
I have a few more tests to attempt to check the second playback crash in jellyfin is the same trace as the enter jellyfin addon, then another addon, then back to jellyfin.
Feel free to beat me at finding a test case :-)
I believe @WallyCZ issue is not the same as ours.

WallyCZ · 2022-03-24T08:58:10Z

That can be the same issue as yours even if stack trace is different since I used the build option --with-pydebug and CFLAGS='-DPy_DEBUG', what you probably haven't. This will enable some python asserts, which can detect the bugs much more sooner than by you. It can have primary and secondary cause. But that's the theory, of course it can be something different. I have noticed that you have always the sqlite module (function pysqlite_microprotocols_add) in your stack traces, so this could be even bug only in sqlite module. Unfortunately, I had to switch to python 3.8 so now I can't do more explorations. I am pretty sure it can be debugged via gdb and resolved even without the deep knowledge of the python internals.

prahal · 2022-03-24T09:20:20Z

@WallyCZ thanks. Could you paste the full build command for --with-pydebug ?
I agree no need for deep python internals knowledges. I was more into deep knowledge of python current weaknesses :-) ie https://bugs.python.org/issue46070 showed me that the fact that there were bugs related to global state used by different interpreters was a known issue for python devs.
Mind I am also making in kodi addon internals. I cannot tell if switching from an addon to the other keep the previously loaded addon state. So kodi devs could help in narrowing a test case in my opinion (this time by knowing the code).

WallyCZ · 2022-03-24T09:27:07Z

Here is Python's package.mk I used https://paste.kodi.tv/acawitaqiy

prahal · 2022-03-24T11:17:14Z

running this on the kodi Odroid C2 with python 3.9.11 segfault:
python3.9 sqlite3_crash.py

# When this program is run using python 3.9.11 it crashes.

import _testcapi
import threading

code = """
import sqlite3
"""

def doIt():
    _testcapi.run_in_subinterp(code)

tt=[]

for i in range(16):
    t = threading.Thread(target=doIt)
    t.start()
    tt.append(t)

for t in tt:
    t.join()

This thanks to https://forum.libreelec.tv/thread/25454-generic-nightly-kodi-restarts-after-loading-sqlite3/ which found that an addon with only import sqlite3 in crashes kodi.

I extracted most of the test case from the initial https://bugs.python.org/issue46070 test case for the windows issue win_py399_crash_reproducer.py.

That should be enough for a python upstream bug report. Still I will do more tests on my side before that so feel free to open it beforehand.
I noticed than on x86_64 python 3.9.2 (debian stable) the segfault does not happen. I want to bisect the python 3.9 code down to a commit.

pretoriano80 · 2022-03-24T13:43:40Z

For now i won't open a bug report with python devs for several reasons.
First, i don't have python skills so this means that it may become a communication "barrier" between me and the devs if more technical discussions are required.

Another reason would be the testing environment, meaning that probably they won't like the idea of testing this on LibreELEC (even if it's clear that this is not caused by LibreELEC).

Probably it would be best if one of the developers behind the affected addons (Netflix,YouTube, etc) open a bug report with cpython devs and i'm saying this because they know the code used in their addons, hence the capacity to better understand the technical details.
And lastly,, Kodi devs may also do this if they want or have enough free time to help on this matter.

prahal · 2022-03-24T14:29:49Z

I can reproduce with a vanilla build of cpython github 3.9.11 tag on x86_64 (I checked a few runs and even on LibreElec the test case only crashes 90% of the time, so if it works the first time, retry). This vanilla build was without LE patches to python.

@pretoriano80 on the addon side, an addon which only code is "import sqlite3" reproduce the crash per https://forum.libreelec.tv/thread/25454-generic-nightly-kodi-restarts-after-loading-sqlite3/ . But on the kodi side, by changing the way they load addon they could workaround the issue. Feel free to bug kodi devs. If at all that will help kodi devs triage the bug reports that relates to this issue.

I will bug report the cpython devs as I have a test case and traces that only involves the python source code that should do on their side.

prahal · 2022-03-24T14:41:24Z

@pretoriano80 Oh sorry you already opened xbmc/xbmc#21045 . Then I will do my side :-)

pretoriano80 · 2022-03-24T14:47:56Z

@pretoriano80 Oh sorry you already opened xbmc/xbmc#21045 . Then I will do my side :-)

No problem! Yeah, the Kodi report was on Android, not so easy to debug as on LibreELEC.
I also pinged @CastagnaIT on Kodi forums about it, he couldn't reproduce it, but that's because he only has Netflix addon installed and it won't crash (tested myself).
YouTube addon is more prone to crashing, even without any other addon being involved.

pretoriano80 · 2022-03-25T04:54:16Z

Here's the journalctl log from the Netflix addon on a debug build - > http://ix.io/3TnX

It seems that it's indeed related to sqlite3.

I have your --with-pydebug in PKG_CONFIGURE_OPTS_TARGET, CFLAGS='-DPy_DEBUG' in pre_configure_target and symlinking of python d suffixed libraries to non suffixed one in Python3 package.mk post_makeinstall_target

NB: I noticed when one upgrade the python to build if the target python library name change I usually get a missing library from dependent packages and kodi does not start. A make clean is then required.

pretoriano80 · 2022-03-26T10:48:39Z

@prahal i used his package.mk that he provided here and no "make clean" was required here.

prahal · 2022-03-26T10:54:51Z

@pretoriano80 sorry, I meant you have to make clean if you want a proper build when one change python suffix or version number (which is the case in this pythn debug build) else your build still contains the old python suffix and the build succeed but is not fine (at runtime it still attempt to load the python library with the old suffix).
Could you retry to make release but this time after a make clean?

WallyCZ · 2022-03-26T12:41:23Z

@prahal I didn't make clean. If you do this, you will need couple of additional changes in build scripts because dependencies will try to ink with incorrect python library (without "d"). The easiest way is to build it with the original make files, then replace that package.mk and build it again without doing make clean. The package.mk contains symlink trick so every dependency will use debug version even if it was linked with non-debug.

prahal · 2022-03-27T23:39:16Z

Thanks for this last tip that help me reproduce your struct bug. It turns out that yours is very likely a different bug. The struct crash happens even if you only wait doing nothing. From my logs, I suspect script.tubed to trigger it.
My kodi logs end up with:

2022-03-28 00:10:00.432 T:674      info <general>: [script.tubecast] ssdp: Starting SSDP server

and more importantly, I get this debug trace with gdbserver and sourcing the LE build python-gdb.py into gdb-multiarch client:

@WallyCZ sorry I forgot to add that the current bug is fixed by reverting cpython commit 52937c26adc35350ca0402070160cf6dc838f359 (for python 3.9). But yours is still there even with that commit reverted.

pretoriano80 · 2022-03-28T05:10:32Z

@prahal you meant script.tubecast?Tubed it's a different addon.

prahal · 2022-03-28T11:53:11Z

@pretoriano80 thank you. @WallyCZ Indeed your issue is triggered by script.tubecast (not script.tubed)

I will revert that commit and try a build without it.
However, if that's the case, then python team will have to find a way out of this. xD

@pretoriano80 my pending push request is in http://sprunge.us/o9kNvR . I also told about this fix in https://bugs.python.org/issue46070 , no reply yet. Note that in 3.11 this commit is fine. It only breaks previous branches where it was backported.

@prahal / @pretoriano80 - if this indeed fixes the issues you are experiencing in 3.9.y - raise a PR to include this patch in LE11?

I'm testing a LE11 build with patched python 3.9.12 right now, :)

@pretoriano80 thank you. @WallyCZ Indeed your issue is triggered by script.tubecast (not script.tubed)

Thank you for your analysis and it looks clear now that it is another issue. And indeed, I am confirming issues with this plugin even with non-debug version (more rare crashes). It crashes Kodi in about 20% of cases I am using it with the release version of python. Although I am not sure if the problem is in the addon itself because in my opinion no addon should crash Kodi even if it would do whatever. Probably should open new ticket on this, but wonder we have enough of information so somebody would bother with this...

pretoriano80 · 2022-03-28T22:49:26Z

@prahal i can confirm that reverting that commit fixed the crashing ,tested with YouTube addon and Netflix .
I only tested with these ones because it was reproducible at 100%, so most likely will also fix other addons affected by this bug.

You said that you already have the PR on hold, so in this case feel free to raise the PR with LibreELEC.

pretoriano80 · 2022-03-29T06:13:22Z

If someone wants to test the patch before a PR is raised,here's my branch with the patch -> https://github.com/pretoriano80/LibreELEC.tv/tree/revert-bpo46070

prahal · 2022-03-30T11:56:56Z

@WallyCZ you should definitely open a bug report, against the addon. Even if it is a python issue the addon manager might be able to help you narrow a test case. You have enough debug if this is an addon issue.
The fact that you cannot produce the LibreElec pydebug build after a make clean is a bad point. If you could get trace with a non pydebug build but with DEBUG="Python3,kodi" it will help check it is not related to this nonclean build.

I will not investigate further this issue for a long while as I have more pressing issues.
At least I had no crash with non pydebug build though I have the addon that crashes with it, ie script.tubecase.
