* Closes issue #23600: Wrong results from tzinfo.fromutc().Alexander Belopolsky2015-09-281-1/+1

* Issue #23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methodsVictor Stinner2015-09-181-8/+63
| | | | | | | | | | | | | of datetime.datetime: microseconds are now rounded to nearest with ties going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding towards zero (ROUND_DOWN). It's important that these methods use the same rounding mode than datetime.timedelta to keep the property: (datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t) It also the rounding mode used by round(float) for example. Add more unit tests on the rounding mode in test_datetime.

* Issue #20320: select.select() and select.kqueue.control() now round the timeoutVictor Stinner2014-02-161-2/+2
| | | | | | aways from zero, instead of rounding towards zero. It should make test_asyncio more reliable, especially test_timeout_rounding() test.
* Issue #20530: Argument Clinic's signature format has been revised again.Larry Hastings2014-02-091-2/+4
| | | | | | | The new syntax is highly human readable while still preventing false positives. The syntax also extends Python syntax to denote "self" and positional-only parameters, allowing inspect.Signature objects to be totally accurate for all supported builtins in Python 3.4.
* Issue #20326: Argument Clinic now uses a simple, unique signature toLarry Hastings2014-01-281-3/+3
| | | | | | | | | | annotate text signatures in docstrings, resulting in fewer false positives. "self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters. Issue #20326: Argument Clinic now generates separate checksums for the input and output sections of the block, allowing external tools to verify that the input has not changed (and thus the output is not out-of-date).

* Issue #20189: Four additional builtin types (PyTypeObject,Larry Hastings2014-01-241-7/+7

* | Fix time.mktime() and datetime.datetime.timestamp() on AIXVictor Stinner2013-06-251-3/+10
| | | | | | | | | | | | On AIX, the C function mktime() alwaysd sets tm_wday, even on error. So tm_wday cannot be used as a sentinel to detect an error, we can only check if the result is (time_t)-1.

* Remove an unnecessary extra copy of the bytes hash function.Gregory P. Smith2012-01-141-15/+1
| | | | | | | | | This copy also had a bug in it, it fails to incorporate the length into the hash by using it as the loop variable so it'll always be -1 by the time it is XORed in. As such: I'm doing this only in Python 3.3 and not backporting as it would change the existing hash behavior of datetime objects.
