* [3.7] bpo-35373: Fix PyInit_timezone() error handling (GH-10864)Miss Islington (bot)2018-12-031-5/+24
| | | | | | | | | | | | | | | | | | | | * bpo-35373: Fix PyInit_timezone() error handling PyInit_timezone() now returns -1 at exit if an exception is raised. Check also explicitly PyUnicode_DecodeLocale() and Py_BuildValue() errors. * bpo-35373: Fix PyInit_time() error handling (GH-10865) * PyInit_time() now returns NULL if an exception is raised. * Rename PyInit_timezone() to init_timezone(). "PyInit_" prefix is a special prefix for function initializing a module. init_timezone() doesn't initialize a module and the function is not exported. (cherry picked from commit 3bb150d8148e3cc08418077a58f43e064b9fde61) (cherry picked from commit 5eb78c75128187a36d8e983027632fa51cc2ff4d) Co-authored-by: Victor Stinner <vstinner@redhat.com>

* Issue #22117: Add a new Python timestamp format _PyTime_t to pytime.hVictor Stinner2015-03-271-21/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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.
* Issue #23646: If time.sleep() is interrupted by a signal, the sleep is nowVictor Stinner2015-03-191-51/+56
| | | | | | | 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.
