Description Mathieu Dubois-Briand 2024-11-28 14:59:43 UTC 
LoggingThread exception handler fails to handle exceptions properly, with the following exception:

>   File "/srv/pokybuild/yocto-worker/qemux86-64-tc/build/meta/lib/oeqa/utils/qemurunner.py", line 750, in threadtarget
>     self.logger.warning("Exception %s in logging thread" % traceback.format_exception(e))
> TypeError: format_exception() missing 2 required positional arguments: 'value' and 'tb'

https://valkyrie.yoctoproject.org/#/builders/66/builds/529/steps/12/logs/stdio

I believe this is because python 3.8 was used here, and this syntax for traceback.format_exception() is only supported since 3.10.

https://docs.python.org/3/library/traceback.html#traceback.format_exception

> Since Python 3.10, instead of passing value and tb, an exception object can be passed as the first argument. If value and tb are provided, the first argument is ignored in order to provide backwards compatibility.

We will have to switch to the old syntax if we want to be compatible with python versions before 3.10.
