Mark Shannon  added the comment:

Don't you need to know if a "call" event is a call or the resumption of a 
generator?

These look great.  Currently, coverage.py only tries to distinguish between 
return/yield, which I guess will now be COMPLETED and SUSPENDED?

[issue47046] Add `f_state` attribute to FrameObjects.

[Mark Shannon]

New submission from Mark Shannon :

When tracing, the event supplied is insufficient to determine what is actually 
happening.

E.g. A "call" event could be a call to a function or resuming a generator or 
coroutine.

Adding a state field to the FrameObject would allow these cases to be 
disambiguated without having to make dubious deductions from `f_lasti` or other 
frame attributes.

The proposed states would be:

FRAME_CREATED# Frame created, but not executed at all
FRAME_SUSPENDED  # Frame suspended after yield or yield from
FRAME_EXECUTING  # Frame is executed normally
FRAME_COMPLETED  # Frame has completed 
FRAME_CLEARED# Frame has been cleared


Ned, any other states that you might need to know about?
