ProcessCanceledException while scanning file #85

Open intgr opened 2 years ago

intgr commented 2 years ago

Step 1: Are you in the right place?

Step 2: Describe your environment

Step 3: Describe the problem:

I just wanted to document for now; I didn't even notice when this happened, but saw this exception in Event Log.

This is probably a new issue introduced in 0.12. Looks like a race condition, IntelliJ can throw ProcessCanceledException earlier before our current exception handler. So should probably move the exception handler

I seem to get a similar error repeatedly. While in the editor, I do see "live" warnings within code generally. But, I suspect that this is a contributing cause of the recent PyCharm crashes that I'm seeing (never saw them before) and the out of memory errors. I guess I'll disable the plug-in for now until I can see some activity here.

FYI: I'm on PyCharm 2021.1 with MyPy 0.942 and mypy-extensions 0.4.3.
