bpo-37205: time.time() cannot fail with fatal error (GH-23314)

2020-11-16T15:08:05+00:00

time.time(), time.perf_counter() and time.monotonic() functions can
no longer fail with a Python fatal error, instead raise a regular
Python exception on failure.

Remove _PyTime_Init(): don't check system, monotonic and perf counter
clocks at startup anymore.

On error, _PyTime_GetSystemClock(), _PyTime_GetMonotonicClock() and
_PyTime_GetPerfCounter() now silently ignore the error and return 0.
They cannot fail with a Python fatal error anymore.

Add py_mach_timebase_info() and win_perf_counter_frequency()
sub-functions.

bpo-37205: time.perf_counter() and time.monotonic() are system-wide (GH-23284)

2020-11-16T12:21:45+00:00

time.perf_counter() on Windows and time.monotonic() on macOS are now
system-wide. Previously, they used an offset computed at startup to
reduce the precision loss caused by the float type. Use
time.perf_counter_ns() and time.monotonic_ns() added in Python 3.7 to
avoid this precision loss.

bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)

2020-11-08T09:05:27+00:00

Co-authored-by:  Lawrence D’Anna 

* Add support for macOS 11 and Apple Silicon (aka arm64)
   
  As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy

* Support building on recent versions of macOS while deploying to older versions

  This allows building installers on macOS 11 while still supporting macOS 10.9.

bpo-40650: Include winsock2.h in pytime.c, instead of a full windows.h (GH-20137)

bpo-38249: Expand Py_UNREACHABLE() to __builtin_unreachable() in the release mode. (GH-16329)

bpo-39502: Fix 64-bit Python PyTime_localtime() on AIX (GH-18285)

2020-02-07T17:56:16+00:00

Fix time.localtime() on 64-bit AIX to support years before 1902 and after 2038.

bpo-38068: Clean up gettimeofday configure logic. (GH-15775)

2019-09-10T10:37:59+00:00

Assume gettimeofday exists and takes two arguments.

bpo-34373: Fix time.mktime() on AIX (GH-12726)

2019-04-09T17:12:26+00:00

Fix time.mktime() error handling on AIX for year before 1970.

Other changes:

* mktime(): rename variable 'buf' to 'tm'.
* _PyTime_localtime():

  * Use "localtime" rather than "ctime" in the error message
    (specific to AIX).
  * Always initialize errno to 0 just in case if localtime_r()
    doesn't set errno on error.
  * On AIX, avoid abs() which is limited to int type.
  * EINVAL constant is now always available.

bpo-34373: fix test_mktime and test_pthread_getcpuclickid tests on AIX (GH-8726)

2018-12-28T13:57:37+00:00

* Fix test_mktime on AIX by adding code to get mktime to behave the
  same way as it does on other *nix systems
* Fix test_pthread_getcpuclickid in AIX by adjusting the test case
  expectations when running on AIX in 32-bit mode

Patch by Michael Felt.
