Victor Stinner 869e1778c0 Issue #22117: Replace usage of _PyTime_ROUND_UP with _PyTime_ROUND_CEILING

Victor Stinner ea9c0dd2c2 Issue #22117: Fix usage of _PyTime_AsTimeval()

Victor Stinner 02937aab13 Issue #22117: Add the new _PyTime_ROUND_FLOOR rounding method for the datetime

Victor Stinner cb29f0177c Issue #22117: Add a new Python timestamp format _PyTime_t to pytime.h
In practice, _PyTime_t is a number of nanoseconds. Its C type is a 64-bit
signed number. It's integer value is in the range [-2^63; 2^63-1]. In seconds,
the range is around [-292 years; +292 years]. In term of Epoch timestamp
(1970-01-01), it can store a date between 1677-09-21 and 2262-04-11.

The API has a resolution of 1 nanosecond and use integer number. With a
resolution on 1 nanosecond, 64-bit IEEE 754 floating point numbers loose
precision after 194 days. It's not the case with this API. The drawback is
overflow for values outside [-2^63; 2^63-1], but these values are unlikely for
most Python modules, except of the datetime module.

New functions:

- _PyTime_GetMonotonicClock()
- _PyTime_FromObject()
- _PyTime_AsMilliseconds()
- _PyTime_AsTimeval()

This change uses these new functions in time.sleep() to avoid rounding issues.

The new API will be extended step by step, and the old API will be removed step
by step. Currently, some code is duplicated just to be able to move
incrementally, instead of pushing a large change at once.

Victor Stinner 9a8089b32a Issue #23646: Enhance precision of time.sleep() and socket timeout when
interrupted by a signal

Add a new _PyTime_AddDouble() function and remove _PyTime_ADD_SECONDS() macro.
The _PyTime_ADD_SECONDS only supported an integer number of seconds, the
_PyTime_AddDouble() has subsecond resolution.

Victor Stinner 79d68f929d Issue #23646: If time.sleep() is interrupted by a signal, the sleep is now
retried with the recomputed delay, except if the signal handler raises an
exception (PEP 475).

Modify also test_signal to use a monotonic clock instead of the system clock.

Victor Stinner 5488449ba4 Issue #22043: Simplify time.perf_counter() on Windows

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.
2014-08-29 16:31:59 +02:00
Victor Stinner 7efb83393c Issue #22287: On UNIX, _PyTime_gettimeofday() now uses

than 2.17).

Victor Stinner 93037498d1 Fix time.mktime() and datetime.datetime.timestamp() on AIX
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.
