Raymond Hettinger added the comment: Jeremy, thanks for the keen eyes. Attaching a revised patch.
Serhiy, pure python code doesn't directly access any of the C-API functions touched by the patch, so timeit-style examples aren't possible. The beneficiaries of the change are external modules. I suppose we could write a small C extension just to time this but that seems like overkill. It is a general purpose optimization technique to reduce the number of memory accesses in fine-grained functions. That technique has worked well elsewhere in the core where measurable progress was made in many small steps that were individually hard to measure. ---------- assignee: serhiy.storchaka -> rhettinger Added file: http://bugs.python.org/file41715/list_check_fastpath2.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26201> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
