STINNER Victor <victor.stin...@gmail.com> added the comment: Here is the version 17 of my patch. This version is mostly complete and so can be reviewed. Summary of the patch:
- Add a _PyTime_t structure to store any timestamp in any resolution, universal structure used by all functions manipulating timestamps instead of C double to avoid loss of precision - Add many functions to create timestamp (set _PyTime_t structure) or to get a timestamp in a specific format (int, float, Decimal, timeval or timespec structure, in milliseconds, etc.) - Round to nearest with ties going away from zero (rounding method called "ROUND_HALF_UP" in Decimal) - Functions creating timestamps get a new optional timestamp argument to specify the requested return type, e.g. time.time(timestamp=int) returns an int - Functions getting timestamps argument now also support decimal.Decimal - Raise an OverflowError instead of a ValueError if a timestamp cannot be stored in a C time_t type The patch is huge, but as I wrote before, I will split it into smaller parts: - Add _PyTime_t API - Use the new API in the time module - Use the new API in the os module - etc. Changes in the version 17 of my patch: - tested on Linux 32/64 bits, OpenBSD 64 bits, FreeBSD 64 bits, Windows 64 bits - fix portability issues (for various time_t and C long sizes) ---------- Added file: http://bugs.python.org/file24505/time_decimal-17.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13882> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
