* bpo-36779: time.tzname returns empty string on Windows if default cod… ↵Miss Islington (bot)2019-06-131-0/+14
| | | | | | | | | | | | | | | | | (GH-13073) Calling setlocale(LC_CTYPE, "") on a system where GetACP() returns CP_UTF8 results in empty strings in _tzname[]. This causes time.tzname to be an empty string. I have reported the bug to the UCRT team and will follow up, but it will take some time get a fix into production. In the meantime one possible workaround is to temporarily change the locale by calling setlocale(LC_CTYPE, "C") before calling _tzset and restore the current locale after if the GetACP() == CP_UTF8 or CP_UTF7 @zooba https://bugs.python.org/issue36779 (cherry picked from commit b4c7defe58695a6670a8fdeaef67a638bbb47e42) Co-authored-by: Paul Monson <paulmon@users.noreply.github.com>

| | | | | | | | | | Python source code uses on several places ifdef sun or defined(sun) without the underscores, which is not standard compliant and shouldn't be used. Defines should check for __sun instead.

* [3.7] bpo-35373: Fix PyInit_timezone() error handling (GH-10864)Victor Stinner2018-12-031-5/+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.

* bpo-29240: Fix locale encodings in UTF-8 Mode (#5170)Victor Stinner2018-01-151-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Modify locale.localeconv(), time.tzname, os.strerror() and other functions to ignore the UTF-8 Mode: always use the current locale encoding. Changes: * Add _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx(). On decoding or encoding error, they return the position of the error and an error message which are used to raise Unicode errors in PyUnicode_DecodeLocale() and PyUnicode_EncodeLocale(). * Replace _Py_DecodeCurrentLocale() with _Py_DecodeLocaleEx(). * PyUnicode_DecodeLocale() now uses _Py_DecodeLocaleEx() for all cases, especially for the strict error handler. * Add _Py_DecodeUTF8Ex(): return more information on decoding error and supports the strict error handler. * Rename _Py_EncodeUTF8_surrogateescape() to _Py_EncodeUTF8Ex(). * Replace _Py_EncodeCurrentLocale() with _Py_EncodeLocaleEx(). * Ignore the UTF-8 mode to encode/decode localeconv(), strerror() and time zone name. * Remove PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() and PyUnicode_EncodeLocale() now ignore the UTF-8 mode: always use the "current" locale. * Remove _PyUnicode_DecodeCurrentLocale(), _PyUnicode_DecodeCurrentLocaleAndSize() and _PyUnicode_EncodeCurrentLocale().
* bpo-29240: Ignore UTF-8 Mode in time module (#5148)Victor Stinner2018-01-111-6/+6
| | | | | | time.strftime() must use the current LC_CTYPE encoding, not UTF-8 if the UTF-8 mode is enabled. Add _PyUnicode_DecodeCurrentLocale() function.

| | | | | | | | | | | | | | | | | | | | | | | | | 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-31806: Use _PyTime_ROUND_TIMEOUT for the timeout argument parsing in ↵Pablo Galindo2017-10-181-1/+1
| | | | | | | | | more functions (#4026) Fix timeout rounding in time.sleep(), threading.Lock.acquire() and socket.socket.settimeout() to round correctly negative timeouts between -1.0 and 0.0. The functions now block waiting for events as expected. Previously, the call was incorrectly non-blocking.
* time.clock() now emits a DeprecationWarning (GH-4020)Victor Stinner2017-10-171-0/+7
| | | | | | | | | | bpo-31803: time.clock() and time.get_clock_info('clock') now emit a DeprecationWarning warning. Replace time.clock() with time.perf_counter() in tests and demos. Remove also hasattr(time, 'monotonic') in test_time since time.monotonic() is now always available since Python 3.5.
* bpo-31773: _PyTime_GetPerfCounter() uses _PyTime_t (GH-3983)Victor Stinner2017-10-161-3/+4
| | | | | | | | * 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 Stinner2017-10-121-17/+11
| | | | | | | | time.clock() and time.perf_counter() now use again C double internally. Remove also _PyTime_GetWinPerfCounterWithInfo(): use _PyTime_GetPerfCounterDoubleWithInfo() instead on Windows.
* bpo-28157: Improvements for the time module documentation (GH-928)Cheryl Sabella2017-10-111-22/+1
| | | | | * Separated functions and constants descriptions in sections. * Added a note about the limitations of timezone constants. * Removed redundant lists from the module docstring.

* timemodule.c: Cast PyUnicode_AsUTF8() to char* (#1294)Victor Stinner2017-04-261-1/+1
| | | | | | | | | | bpo-28769 changed PyUnicode_AsUTF8() return type from const char* to char* in Python 3.7, but tm_zone field type of the tm structure is char* on FreeBSD. Cast PyUnicode_AsUTF8() to char* in gettmarg() to fix the warning: Modules/timemodule.c:443:20: warning: assigning to 'char *' from 'const char *' discards qualifiers
* tmtotuple(): use time_t for gmtoff (#1276)Victor Stinner2017-04-241-3/+3
| | | | | | | timegm() return type is time_t, not int. Use time_t to prevent the following compiler warning on Windows: timemodule.c: warning C4244: '=': conversion from 'time_t' to 'int', possible loss of data
* Only define get_zone() and get_gmtoff() if needed (#1193)Victor Stinner2017-04-201-0/+2
| | | | | | | | | Only define the get_zone() and get_gmtoff() private functions in the time module if these functions are needed to initialize the module. The change fixes the following warnings on AIX: Modules/timemodule.c:1175:1: warning: 'get_gmtoff' defined but not used [-Wunused-function] Modules/timemodule.c:1164:1: warning: 'get_zone' defined but not used [-Wunused-function]
