pep447-2015-07-25-v2.txt changes two things w.r.t. the patch earlier today:
1) The performance problems w.r.t. the method_cache are gone
2) Added code for handling python exceptions other than AttributeError in
calls to __getdescriptor__.
This code requires some tests to make sure the error handling code
is correct.
The new patch also adds some more tests, and adds extra MCACHE_STATS counters. Those aren't part of the proposal but were helpful to find the problem w.r.t. 1).
As I mentioned before implementing __getdescriptor__ in Python is bad for performance of instances of that metaclass. AFAIK that cannot be helped, doing that will just execute a lot more Python code. |
