* bpo-23395: Fix PyErr_SetInterrupt if the SIGINT signal is ignored or not ↵Matěj Cepl2019-05-231-4/+9
| | | | | handled (GH-7778) ``_thread.interrupt_main()`` now avoids setting the Python error status if the ``SIGINT`` signal is ignored or not handled by Python.
* bpo-36842: Implement PEP 578 (GH-12613)Steve Dower2019-05-2311-3/+257
| | | Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.
* bpo-33164: update blake2 implementation (GH-6286)David Carlier2019-05-2322-675/+18361

* bpo-36084: Add native thread ID (TID) to threading.Thread (GH-13463)Jake Tesler2019-05-221-0/+20
| | | | Add native thread ID (TID) to threading.Thread objects (supported platforms: Windows, FreeBSD, Linux, macOS).

* bpo-36829: Add sys.unraisablehook() (GH-13187)Victor Stinner2019-05-221-0/+15
| | | | | | | | | | | | | | | | | | | Add new sys.unraisablehook() function which can be overridden to control how "unraisable exceptions" are handled. It is called when an exception has occurred but there is no way for Python to handle it. For example, when a destructor raises an exception or during garbage collection (gc.collect()). Changes: * Add an internal UnraisableHookArgs type used to pass arguments to sys.unraisablehook. * Add _PyErr_WriteUnraisableDefaultHook(). * The default hook now ignores exception on writing the traceback. * test_sys now uses unittest.main() to automatically discover tests: remove test_main(). * Add _PyErr_Init(). * Fix PyErr_WriteUnraisable(): hold a strong reference to sys.stderr while using it
* bpo-36648: fix mmap issue for VxWorks (GH-12394)Lihua Zhao2019-05-211-0/+7
| | | | | The mmap module set MAP_SHARED flag when map anonymous memory, however VxWorks only support MAP_PRIVATE when map anonymous memory, this commit clear MAP_SHARED and set MAP_PRIVATE.
* bpo-31904: Add posix module support for VxWorks (GH-12118)pxinwr2019-05-212-12/+70

* bpo-36965: Fix includes in main.c on Windows with non-MSC compilers (GH-13421)Erik Janssens2019-05-211-2/+2
| | | | Include windows.h rather than crtdbg.h to get STATUS_CONTROL_C_EXIT constant. Moreover, include windows.h on Windows, not only when MSC is used.

| | | | | | | | | | | | | | | * Add _PyInitError functions: * _PyInitError_Ok() * _PyInitError_Error() * _PyInitError_NoMemory() * _PyInitError_Exit() * _PyInitError_IsError() * _PyInitError_IsExit() * _PyInitError_Failed() * frozenmain.c and _testembed.c now use functions rather than macros. * Move _Py_INIT_xxx() macros to the internal API. * Move _PyWstrList_INIT macro to the internal API.

| | | | | | | | | Py_Main() and _Py_RunMain() now return the exitcode rather than calling Py_Exit(exitcode) when calling PyErr_Print() if the current exception type is SystemExit. * Add _Py_HandleSystemExit(). * Add pymain_exit_err_print(). * Add pymain_exit_print().
* bpo-36782: Created C API wrappers and added missing tests for functions in ↵Edison A2019-05-171-1/+169

* bpo-36763: Add _PyCoreConfig_InitPythonConfig() (GH-13388)Victor Stinner2019-05-171-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions to get the Python interpreter behavior: * _PyPreConfig_InitPythonConfig() * _PyCoreConfig_InitPythonConfig() Add new functions to get an isolated configuration: * _PyPreConfig_InitIsolatedConfig() * _PyCoreConfig_InitIsolatedConfig() Replace _PyPreConfig_INIT and _PyCoreConfig_INIT with new functions _PyPreConfig_Init() and _PyCoreConfig_Init(). _PyCoreConfig: set configure_c_stdio and parse_argv to 0 by default to behave as Python 3.6 in the default configuration. _PyCoreConfig_Read() no longer sets coerce_c_locale_warn to 1 if it's equal to 0. coerce_c_locale_warn must now be set to -1 (ex: using _PyCoreConfig_InitPythonConfig()) to enable C locale coercion warning. Add unit tests for _PyCoreConfig_InitPythonConfig() and _PyCoreConfig_InitIsolatedConfig(). Changes: * Rename _PyCoreConfig_GetCoreConfig() to _PyPreConfig_GetCoreConfig() * Fix core_read_precmdline(): handle parse_argv=0 * Fix _Py_PreInitializeFromCoreConfig(): pass coreconfig.argv to _Py_PreInitializeFromPyArgv(), except if parse_argv=0
* bpo-36763: Add PyMemAllocatorName (GH-13387)Victor Stinner2019-05-171-1/+1
| | | | | | | | | | | | | | * Add PyMemAllocatorName enum * _PyPreConfig.allocator type becomes PyMemAllocatorName, instead of char* * Remove _PyPreConfig_Clear() * Add _PyMem_GetAllocatorName() * Rename _PyMem_GetAllocatorsName() to _PyMem_GetCurrentAllocatorName() * Remove _PyPreConfig_SetAllocator(): just call _PyMem_SetupAllocators() directly, we don't have do reallocate the configuration with the new allocator anymore! * _PyPreConfig_Write() parameter becomes const, as it should be in the first place!
* bpo-36908: 'This module is always available' isn't helpful. (#13297)Ned Batchelder2019-05-172-4/+4
| | | | Makes the documentation of math and cmath module more helpful for the beginners.
* bpo-36763: Remove _PyCoreConfig.program (GH-13373)Victor Stinner2019-05-171-2/+2
| | | Use _PyCoreConfig.program_name instead.
* bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-174-8/+16
| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>
* bpo-36763: Add _Py_InitializeMain() (GH-13362)Victor Stinner2019-05-161-3/+3
| | | | | | | | | * Add a private _Py_InitializeMain() function. * Add again _PyCoreConfig._init_main. * _Py_InitializeFromConfig() now uses _init_main to decide if _Py_InitializeMainInterpreter() should be called. * _PyCoreConfig: rename _frozen to pathconfig_warnings, its value is now the opposite of Py_FrozenFlag. * Add an unit test for _init_main=0 and _Py_InitializeMain().
* bpo-36763: Add _PyCoreConfig.parse_argv (GH-13361)Victor Stinner2019-05-161-1/+1
| | | | | | | * _PyCoreConfig_Read() doesn't parse nor update argv if parse_argv is 0. * Move path configuration fields in _PyCoreConfig. * Add an unit test for parse_argv=0. * Remove unused "done": label in _Py_RunMain().
* bpo-36763: _PyInitError always use int for exitcode (GH-13360)Victor Stinner2019-05-161-26/+22
| | | | | | | | | | | | | | | | | We cannot use "unsigned int" for exitcode on Windows, since Py_Main() and _Py_RunMain() always return an "int". Changes: * _PyPathConfig_ComputeSysPath0() now returns -1 if an exception is raised. * pymain_run_python() no longer uses _PyInitError but display the exception and set exitcode to 1 in case of error. * Fix _Py_RunMain(): return an exitcode rather than calling exit() on pymain_run_python() failure. * _Py_ExitInitError() no longer uses ExitProcess() on Windows, use exit() on all platforms. * _Py_ExitInitError() now fails with a fatal error if 'err' is not an error not an exit.

* Change WriterObj.writeline to WriterObj.write (GH-12344)Rémi Lapeyre2019-05-141-10/+12
| | | This cleans the csv module a bit, I don't think it requires a bpo issue or a news entry.
* bpo-36728: Remove PyEval_ReInitThreads() from C API (GH-13241)Victor Stinner2019-05-131-4/+15
| | | | | | | | Remove the PyEval_ReInitThreads() function from the Python C API. It should not be called explicitly: use PyOS_AfterFork_Child() instead. Rename PyEval_ReInitThreads() to _PyEval_ReInitThreads() and add a 'runtime' parameter.
* bpo-36895: remove time.clock() as per removal notice. (GH-13270)Matthias Bussonnier2019-05-131-50/+0
| | | | `time.clock()` was deprecated in 3.3, and marked for removal removal in 3.8; this thus remove it from the time module.

| | | | | | | | | | | | | | | | | | | | | | | | | Add "struct _ceval_runtime_state *ceval = &_PyRuntime.ceval;" local variables to function to better highlight the dependency on the global variable _PyRuntime and to point directly to _PyRuntime.ceval field rather than on the larger _PyRuntime. Changes: * Add _PyRuntimeState_GetThreadState(runtime) macro. * Add _PyEval_AddPendingCall(ceval, ...) and _PyThreadState_Swap(gilstate, ...) functions. * _PyThreadState_GET() macro now calls _PyRuntimeState_GetThreadState() using &_PyRuntime. * Add 'ceval' parameter to COMPUTE_EVAL_BREAKER(), SIGNAL_PENDING_SIGNALS(), _PyEval_SignalAsyncExc(), _PyEval_SignalReceived() and _PyEval_FiniThreads() macros and functions. * Add 'tstate' parameter to call_function(), do_call_core() and do_raise(). * Add 'runtime' parameter to _Py_CURRENTLY_FINALIZING(), _Py_FinishPendingCalls() and _PyThreadState_DeleteExcept() macros and functions. * Declare 'runtime', 'tstate', 'ceval' and 'eval_breaker' variables as constant.
* bpo-35983: skip trashcan for subclasses (GH-11841)Jeroen Demeyer2019-05-102-2/+78
| | | | | Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism. Patch by Jeroen Demeyer.
