document Keyboard Interrupt will only show a stack trace with --fulltrace

Sometimes (a test runs very long for no good reason, goes into endless recursion or a loop) I want an interrupt with stack trace / pdb when I press ^C.

Could you please add an option which turns off catching KeyboardInterrupt and handles it like any other error?

Today, if you pass --fulltrace you'd see at least a stack trace. Would it make sense to drop to PDB on keyboard interrupt when "--pdb" is specified? (I'd like to avoid adding another command line option if it can be avoided).

Hi,

Yes, that would be great; my system has a pretty deep object hierarchy and
I'd want to check if the recursion I see is genuine.

I didn't check --full-trace, assuming that it only affects how much of the
stack trace is displayed, but not whether they're shown at all; you might
want to amend the documentation.

OK. Please note, though, that I am spending my time on reviewing pull requests and implementing features or fixing bugs that are high priority to me. That's requiring quite a lot of my time already. IOW, while i welcome suggestions i also depend on pull requests and people wanting to improve things for their own use cases themselves.

as noted by the original reporter it was a bit hard to figure

This issue is identical or closely related to #1366.

Should the --fulltrace option be further documented?

Should the --fulltrace option be further documented?

That would be great. Could you open a PR @omarkohl ? 😁
