* bpo-31784: Implement PEP 564: add time.time_ns() (#3989)Victor Stinner2017-11-021-19/+86
| | | | | | | | | | | | | | | | | | | | | | | | | Add new time functions: * time.clock_gettime_ns() * time.clock_settime_ns() * time.monotonic_ns() * time.perf_counter_ns() * time.process_time_ns() * time.time_ns() Add new _PyTime functions: * _PyTime_FromTimespec() * _PyTime_FromNanosecondsObject() * _PyTime_FromTimeval() Other changes: * Add also os.times() tests to test_os. * pytime_fromtimeval() and pytime_fromtimeval() now return _PyTime_MAX or _PyTime_MIN on overflow, rather than undefined behaviour * _PyTime_FromNanoseconds() parameter type changes from long long to _PyTime_t

* bpo-31773: _PyTime_GetPerfCounter() uses _PyTime_t (GH-3983)Victor Stinner2017-10-161-36/+122
| | | | | | | | * Rewrite win_perf_counter() to only use integers internally. * Add _PyTime_MulDiv() which compute "ticks * mul / div" in two parts (int part and remaining) to prevent integer overflow. * Clock frequency is checked at initialization for integer overflow. * Enhance also pymonotonic() to reduce the precision loss on macOS (mach_absolute_time() clock).
* bpo-31773: time.perf_counter() uses again double (GH-3964)Victor Stinner2017-10-121-15/+21
| | | | | | | | time.clock() and time.perf_counter() now use again C double internally. Remove also _PyTime_GetWinPerfCounterWithInfo(): use _PyTime_GetPerfCounterDoubleWithInfo() instead on Windows.
* Cleanup pytime.c (#3955)Victor Stinner2017-10-111-54/+76
| | | | | * Move _PyTime_overflow() at the top * Move assertion on numerator into _PyTime_ObjectToDenominator() * PEP 7: add { ... } to if blocks
* bpo-31415: Add _PyTime_GetPerfCounter() and use it for -X importtime (#3936)Victor Stinner2017-10-101-10/+71
| | | | | * Add _PyTime_GetPerfCounter() * Use _PyTime_GetPerfCounter() for -X importtime
* bpo-31338 (#3374)Barry Warsaw2017-09-151-9/+3
| | | | | | | * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.

| | | | | | Introduced platform independent _PyTime_localtime API that is similar to POSIX localtime_r, but available on all platforms. Patch by Ed Schouten.

| * pytime.c: rename pygettimeofday_new() to pygettimeofday()Victor Stinner2015-11-101-3/+3
| | | | | | | | I forgot to rename it in my previous refactoring of pytime.c.
| * Issue #25155: Fix _PyTime_Divide() roundingVictor Stinner2015-09-181-3/+8
| | | | | | | | | | _PyTime_Divide() rounding was wrong: copy code from Python default which has now much better unit tests.
| * Issue #25155: Add _PyTime_AsTimevalTime_t() functionVictor Stinner2015-09-181-38/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On Windows, the tv_sec field of the timeval structure has the type C long, whereas it has the type C time_t on all other platforms. A C long has a size of 32 bits (signed inter, 1 bit for the sign, 31 bits for the value) which is not enough to store an Epoch timestamp after the year 2038. Add the _PyTime_AsTimevalTime_t() function written for datetime.datetime.now(): convert a _PyTime_t timestamp to a (secs, us) tuple where secs type is time_t. It allows to support dates after the year 2038 on Windows. Enhance also _PyTime_AsTimeval_impl() to detect overflow on the number of seconds when rounding the number of microseconds.

* | Fix _PyTime_AsTimevalStruct_impl() on OpenBSDVictor Stinner2015-10-011-2/+3
| | | | | | | | | | | | On the x86 OpenBSD 5.8 buildbot, the integer overflow check is ignored. Copy the tv_sec variable into a Py_time_t variable instead of "simply" casting it to Py_time_t, to fix the integer overflow check.
* | Backout change 28d3bcb1bad6: "Try to fix _PyTime_AsTimevalStruct_impl() onVictor Stinner2015-09-301-3/+2
| | | | | | | | | | OpenBSD", I'm not sure that the change was really needed. I read the test result of an old build because the OpenBSD was 100 builds late.
* | Try to fix _PyTime_AsTimevalStruct_impl() on OpenBSDVictor Stinner2015-09-291-2/+3
| | | | | | | | It looks like the check for integer overflow doesn't work on x86 OpenBSD 5.8.

* | pytime: add _PyTime_check_mul_overflow() macro to avoid undefined behaviourVictor Stinner2015-09-101-11/+24
| | | | | | | | | | | | | | | | | | | | | | 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.

* | Fix test_time on WindowsVictor Stinner2015-09-101-20/+8

* | test_time: rewrite PyTime API rounding testsVictor Stinner2015-09-091-6/+10
| | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Issue #23517: Fix implementation of the ROUND_HALF_UP rounding mode inVictor Stinner2015-09-041-4/+4
| | | | | | | | | | datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp(). microseconds sign should be kept before rounding.
* | Don't abuse volatile keyword in pytime.cVictor Stinner2015-09-031-2/+4

| * Issue #24707: Remove assertion in monotonic clockVictor Stinner2015-09-021-10/+0
| | | | | | | | | | | | | | | | | | | | Don't check anymore at runtime that the monotonic clock doesn't go backward. Yes, it happens. It occurs sometimes each month on a Debian buildbot slave running in a VM. The problem is that Python cannot do anything useful if a monotonic clock goes backward. It was decided in the PEP 418 to not fix the system, but only expose the clock provided by the OS.
