New submission from Alexander Belopolsky <belopol...@users.sourceforge.net>:
The original RFE at issue 7989 was: """ After discussion on numerous issues, python-dev, and here at the PyCon sprints, it seems to be a good idea to move timemodule.c to _timemodule.c and convert as much as possible into pure Python. The same change seems good for datetime.c as well. """ See msg99774. I have changed issue 7989 to cover datetime only because I argued that as a thin wrapper around C library calls, this module is an exception to the general rule that pure python implementations are a good idea. See msg107303. No I realize that in order to break circular dependency between time and datetime modules, it will be helpful to create an _time module that would provide lower than time module access to system facilities and datetime and time modules would be use _time module to implement higher level interfaces either in C or in Python. I believe _time module should become the home of the gettimeofday() method and pure python implementation of time.time() will be def time() s, us = _time.gettimeofday() return s + 1e-6 * us Similarly time.sleep() can be implemented in terms of lower level POSIX nanosleep() method. Lower level localtime() function can provide access to tm_zone and tm_gmtoff members of struct tm (where available) without concerns about backward compatibility. ---------- assignee: belopolsky components: Extension Modules, Library (Lib) messages: 113073 nosy: amaury.forgeotdarc, belopolsky, brett.cannon, brian.curtin, davidfraser, durban, giampaolo.rodola, haypo, lemburg, mark.dickinson, merwok, pitrou, r.david.murray, rhettinger, techtonik, tim_one priority: normal severity: normal status: open title: Add pure Python implementation of time module to CPython type: feature request versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9528> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
