Exception on python action plugin code

[jacobw]

Describe the bug
"Exception on python action plugin code" window pops up when I click the plugin button in the PCB Editor. Plugin doesn't work after this point.

To Reproduce
Steps to reproduce the behavior:

1. Go to PCB Editor
2. Click on JLCPCB Tools icon
3. See error

Traceback (most recent call last):

RuntimeError: wrapped C/C++ object of type JLCPCBTools has been deleted

I have just updated to the latest plugin release (2024.05.01) and this started happening. The first time I click the icon it downloads the db ok, then after that this happens every time. I tried uninstalling and reinstalling and no change.

Plugin works

I can confirm I get the same issue. A sort of workaround seems to be:
save everything then quit and reopen Kicad.
This seems to work, but sometimes the crash will happen again.

I have exactly same issue on Windows 11 + KiCad 8.0.2 + kicad-jlcpcb-tools 2024.05.01
Exiting KiCad and relaunching it fix temporary the issue.

[abregnsbo]

I also have this issue on Windows 10 + KiCad 8.0.2 + kicad-jlcpcb-tools 2024.05.01.

[chmorgan]

So it looks like the issue is due to some mismatch of memory being freed on one side (python vs. qt).

There are a number of issues with similar text on stack overflow, like:

https://stackoverflow.com/questions/75531812/getting-past-runtimeerror-wrapped-c-c-object-of-type-has-been-deleted

@whmountains any thoughts on what might be going on here? Clearly its due to the message sending change but its not clear which object isn't valid or being properly retained.

[chmorgan]

@Bouni any thoughts? I don't quite follow which object is deleted on the c++ side but not on the python side...

[chmorgan]

or who we might be able to ask to take a look? We could revert the change until we can get a fix but the wrong thread updating the UI was causing a separate issue

[DomoticX]

I also have the same error on KiCad 8.0.2 and JLCPCB tools v2024.05.01

[KnightHill]

Same issue as @DomoticX under Manjaro with KiCad 8.0.2. Not possible to downgrade, as many other libraries were changed during the last update.

[chmorgan]

As an update I'm discussing the issue on the wxPython forums, https://discuss.wxpython.org/t/help-debugging-a-runtimeerror-wrapped-c-c-object-of-type-jlcpcbtools-has-been-deleted-error/36948, as I kind of understand the problem but not why or how it's happening in this case. Will update here when I know more.

[chmorgan]

Also asked here on SO, https://stackoverflow.com/questions/78534034/wxpython-runtimeerror-wrapped-c-c-object-of-type-jlcpcbtools-has-been-delete

[chmorgan]

Can someone with this issue please try #478 to see if this resolves the crash for them? With the help of Aleksandr Shvartzkop I was able to understand the issue and reproduce it here and fix it. I'm not able to reproduce the crash any more.

[DomoticX]

I still have the error on Kicad 8.0.2, OS: Windows 11

My steps:

• Delete any previous JLCPCB plugin via plugin manager
• Install plugin via Plugin manager: KiCAD-PCM-2024.05.01.zip
• Overwrite mainwindow.py with changed one: 30856ea
• Close KiCad
• Restart Kicad and open PCB
• Open JLCPCB plugin

Result is slightly diffrent...

[chmorgan]

@DomoticX can you confirm you've totally exited out of kicad and are still seeing the issue?

The crash is slightly different and I wasn't seeing it as that logging call in library.py:57 is only called when there isn't a datadir. So I modified library setup() locally to log even if it doesn't create the directory and not seeing the crash here.

There are also no other calls to addHandler() without matching removeHandler(), only remaining question is maybe quit_dialog() isn't the correct place to clean up the loggers.

[DomoticX]

@chmorgan well i closed all there is, and restarted KiCad, seems to be working now without crashing ;-) thank you!

[chmorgan]

@DomoticX whew. At least that’s consistent with the theory of operation behind the fix heh

@whmountains can you review the open PR so we can get it merged and a new version released?

[Nick-Doe]

I can confirm that this fixed my issues so far
https://forum.kicad.info/t/issues-the-version-8-0-3-rc-and-jlcpcb-tools/51392

[Bouni]

I just released 2024.06.01 which should include the fix for this.

[bvernoux]

I confirm that issue is now fixed with 2024.06.01 (tested with Windows 11 Pro x64 + KiCad 8.0.3)
