Access fixture finalizer tracebacks in pytest_fixture_post_finalizer

[phillid]

Hi all,

I have (inherited) a pytest_fixture_post_finalizer hook which is trying to get and handle (display, etc) stack traces of exceptions thrown by fixture finalisers. Since fixturedef.cached_result only records exceptions on setup (

pytest/src/_pytest/fixtures.py

Line 1205 in 01de0c1

fixturedef.cached_result = (result, my_cache_key, None)

) the guy before me (ab)used sys.exc_info in the hook to get finalizer exceptions. After 434282e this no longer works due to ordering issues; the hook is called between the exception being caught, and re-raised.

Are there any suggestions or official guidance on how access fixture finaliser traceback(s) info from a plugin?

Thanks

My understanding is that we need to pass the exception group to the hook to support that
