Victor Stinner 5789cfbb56 Issue #22043: Fix pymonotonic(), use tv_usec=-1 as a marker to skip
the monotonic test
2014-09-03 09:43:48 +02:00
Victor Stinner ae58649721 Issue #22043: time.monotonic() is now always available
threading.Lock.acquire(), threading.RLock.acquire() and socket operations now
use a monotonic clock, instead of the system clock, when a timeout is used.

Victor Stinner 9bb758cee7 Issue #22043: Fix _PyTime_gettimeofday() if HAVE_GETTIMEOFDAY
Ensure also that the tv_usec field is consistent: in range [0; 999999].

Victor Stinner 0011124dc2 Issue #22043: _PyTime_Init() now checks if the system clock works.
Other changes:

* The whole _PyTime API is private (not defined if Py_LIMITED_API is set)
* _PyTime_gettimeofday_info() also returns -1 on error
* Simplify PyTime_gettimeofday(): only use clock_gettime(CLOCK_REALTIME) or
  gettimeofday() on UNIX. Don't fallback to ftime() or time() anymore.

Victor Stinner 7efb83393c Issue #22287: On UNIX, _PyTime_gettimeofday() now uses
clock_gettime(CLOCK_REALTIME) if available. As a side effect, Python now
depends on the librt library on Solaris and on Linux (only with glibc older
than 2.17).

Victor Stinner 3c1b379ebd Issue #20320: select.select() and select.kqueue.control() now round the timeout
aways from zero, instead of rounding towards zero.

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

Victor Stinner 2b89fdf7eb PEP 418: Rename adjusted attribute to adjustable in time.get_clock_info() result
Fix also its value on Windows and Linux according to its documentation:
"adjustable" indicates if the clock *can be* adjusted, not if it is or was
adjusted.

In most cases, it is not possible to indicate if a clock is or was adjusted.

Larry Hastings 76ad59b7e8 Issue #14127: Add ns= parameter to utime, futimes, and lutimes.
Removed futimens as it is now redundant.
Changed shutil.copystat to use st_atime_ns and st_mtime_ns from os.stat
and ns= parameter to utime--it once again preserves exact metadata on Linux!

Benjamin Peterson 49a69e4d48 strip is_ prefixes on clock_info fields 2012-05-01 09:38:34 -04:00
Victor Stinner ec89539ccc Issue #14428, #14397: Implement the PEP 418
* Rename time.steady() to time.monotonic()
 * On Windows, time.monotonic() uses GetTickCount/GetTickCount64() instead of
   QueryPerformanceCounter()
 * time.monotonic() uses CLOCK_HIGHRES if available
 * Add time.get_clock_info(), time.perf_counter() and time.process_time()
   functions

Victor Stinner bd273c1ec3 Issue #14180: Fix an invalid rounding when compiler optimization are enabled
Use volatile keyword to disable localy unsafe float optimizations.

Victor Stinner 3a31dd407a Issue #14180: Remove commented code 2012-03-13 13:50:34 +01:00
Victor Stinner 5d272cc6a2 Close #14180: Factorize code to convert a number of seconds to time_t, timeval or timespec
time.ctime(), gmtime(), time.localtime(), datetime.date.fromtimestamp(),
datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now
raises an OverflowError, instead of a ValueError, if the timestamp does not fit
in time_t.

datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now
round microseconds towards zero instead of rounding to nearest with ties going
away from zero.

Victor Stinner 643cd68ea4 Issue #13964: signal.sigtimedwait() timeout is now a float instead of a tuple
Add a private API to convert an int or float to a C timespec structure.

Victor Stinner 09225b73c1 Issue #13845: time.time() now uses GetSystemTimeAsFileTime() instead of ftime()
to have a resolution of 100 ns instead of 1 ms (the clock accuracy is between
0.5 ms and 15 ms).

Alexander Belopolsky 6fc4ade2bb Issue #9079: Added _PyTime_gettimeofday(_PyTime_timeval *tp) to C API
exposed in Python.h.  This function is similar to POSIX
gettimeofday(struct timeval *tp), but available on platforms without
gettimeofday().
