Victor Stinner 717a32b755 Fix typo in test_time.py 2016-08-17 11:07:21 +02:00
Victor Stinner c60542b12b pytime: add _PyTime_check_mul_overflow() macro to avoid undefined behaviour 
Overflow test in test_FromSecondsObject() fails on FreeBSD 10.0 buildbot which
uses clang. clang implements more aggressive optimization which gives
different result than GCC on undefined behaviours.

Check if a multiplication will overflow, instead of checking if a
multiplicatin had overflowed, to avoid undefined behaviour.

Add also debug information if the test on overflow fails.

Victor Stinner 4237d3474c Fix test_time on platform with 32-bit time_t type 
Filter values which would overflow when converted to a C time_t type.

Victor Stinner 9c72f9b30a Fix test_time on Windows 
* Filter values which would overflow on conversion to the C long type
  (for timeval.tv_sec).
* Adjust also the message of OverflowError on PyTime conversions
* test_time: add debug information if a timestamp conversion fails

Victor Stinner 3e2c8d84c6 test_time: rewrite PyTime API rounding tests 
Drop all hardcoded tests. Instead, reimplement each function in Python, usually
using decimal.Decimal for the rounding mode.

Add much more values to the dataset. Test various timestamp units from
picroseconds to seconds, in integer and float.

Enhance also _PyTime_AsSecondsDouble().

Victor Stinner 7667f58151 Issue #23517: fromtimestamp() and utcfromtimestamp() methods of 
datetime.datetime now round microseconds to nearest with ties going to nearest
even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards
-Infinity (ROUND_FLOOR).

pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix
also _PyTime_Divide() for negative numbers.

_PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing
rounding modes.

Victor Stinner 8c8b4e0ebf Issue #11188, #19748: mktime() returns -1 on error. On Linux, the tm_wday field 
is used as a sentinel () to detect if -1 is really an error or a valid
timestamp. On AIX, tm_wday is unchanged even on success and so cannot be used
as a sentinel.

Victor Stinner 3c1b379ebd Issue #20320: select.select() and select.kqueue.control() now round the timeout

It should make test_asyncio more reliable, especially test_timeout_rounding() test.
