Building off of #2835, this PR replaces the remaining instances of
stack()
withstack(0)
, so that we avoid getting context information for the first frame of the stack, which is expensive.I also discovered that we were calling
traceback.format_list(traceback.extract_stack()[-10:])
, which does the following:To fix this, I've made
extract_stack()
use thelimit=10
parameter.Finally, I optimized
_path_utils.py
to only retrieve two frames from the stack, instead of retrieving the entire stack and then discarding everything but the second frame :)
