Code Snippet / Additional information

I started to experience this when I use decorator and wrap method is in a class.
For example, this works:

@profile
def fromApp(self, message, session_ID):
pass

But bug happens when I try to use it with the class:

@TimeWorker().profile
def fromApp(self, message, session_ID):
pass

But currently I have the same problem even if I don't use it.

[erictraut]

Thanks for reporting the problem. Unfortunately, I don't have enough context to diagnose the problem from the logs above. We've seen similar stack traces in our crash data, but I haven't had enough context to repro the problem or determine the root cause. There is something about the structure of this code that is triggering the bug. I'm very interested in figuring this one out!

You mentioned that the problem occurs when you applied the decorator @TimeWorker().profile. Is there anything more you can tell me about that decorator?

By any chance, are you able to narrow down the problem to a self-contained repro that you could post?

Any additional clues would be very much appreciated!

[georgeivanyan]

I'm trying to narrow it down and find the source of the problem. I've got rid of the mentioned decorator and still see the problem. It's quite peculiar, as this step has previously helped me to resolve this. I have a specific py file in the project where the error always occurs whenever I simply open the file.
I've checked for additional details in the log and this is the error message that shows up: "Typeshed path not found ". I'm not sure if it's related but worth mentioning:

Are there any specific steps you can suggest that I can follow to help narrow it down?

[erictraut]

Thanks for the additional logs. I don't see anything that's suspicious.

The technique I typically use to narrow down reproducible problems like this is to temporarily comment out code until the problem goes away. If it's a large file, I binary search it (comment out half the code, etc.) to speed up the search. This usually narrows it down pretty quickly to a single function or block.

[georgeivanyan]

I narrow it down to this part:

When I add or remove message_start variable, I get the error.

import quickfix as fix
 
class FIX_application(fix.Application):
    
     def __init__(self, options):
        self.options = options
        message_start = f"Implementation was run with options:\nDB: {self.options.db}"

        super().__init__()

I'm getting more or less the same error too, specifically, importing PySimpleGUI that is a pretty big library

@erictraut tag me if you need any kinda of log or report (w/ instruction to generate them), or if I should file a new issue

[erictraut]

Thanks @georgeivanyan and @DeusAres for the repros. Very helpful. I was able to find the root cause of the problem. It will be fixed in the next release.

This issue has been fixed in version 2022.2.3, which we've just released. You can find the changelog here: CHANGELOG.md
