* bpo-26836: Add ifdefs for all MFD_HUGE* constants (GH-13666)Zackery Spytz2019-05-291-0/+28
| | | https://bugs.python.org/issue26836
* bpo-32388: Remove cross-version binary compatibility requirement in tp_flags ↵Antoine Pitrou2019-05-2911-26/+19
| | | | | | | | (GH-4944) It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags. This will reduce the risk of running out of bits in the 32-bit tp_flags value.
* bpo-26836: Add os.memfd_create() (#13567)Zackery Spytz2019-05-292-1/+124
| | | | | | | | | | | | | | | | | | | | * bpo-26836: Add os.memfd_create() * Use the glibc wrapper for memfd_create() Co-Authored-By: Christian Heimes <christian@python.org> * Fix deletions caused by autoreconf. * Use MFD_CLOEXEC as the default value for *flags*. * Add memset_s to configure.ac. * Revert memset_s changes. * Apply the requested changes. * Tweak the docs.
* bpo-22385: Support output separators in hex methods. (#13578)Gregory P. Smith2019-05-292-25/+123
| | | | | | | | | | | | | | | | | | * bpo-22385: Support output separators in hex methods. Also in binascii.hexlify aka b2a_hex. The underlying implementation behind all hex generation in CPython uses the same pystrhex.c implementation. This adds support to bytes, bytearray, and memoryview objects. The binascii module functions exist rather than being slated for deprecation because they return bytes rather than requiring an intermediate step through a str object. This change was inspired by MicroPython which supports sep in its binascii implementation (and does not yet support the .hex methods). https://bugs.python.org/issue22385

* bpo-37076: _thread.start_new_thread() calls _PyErr_WriteUnraisableMsg() ↵Victor Stinner2019-05-291-14/+4
| | | | | | | (GH-13617) _thread.start_new_thread() now logs uncaught exception raised by the function using sys.unraisablehook(), rather than sys.excepthook(), so the hook gets access to the function which raised the exception.
* bpo-37001: Makes symtable.symtable have parity with compile for input (#13483)Dino Viehland2019-05-282-23/+24

* bpo-1230540: Add threading.excepthook() (GH-13515)Victor Stinner2019-05-271-0/+156
| | | | | | | | | | | | | | | | | | | Add a new threading.excepthook() function which handles uncaught Thread.run() exception. It can be overridden to control how uncaught exceptions are handled. threading.ExceptHookArgs is not documented on purpose: it should not be used directly. * threading.excepthook() and threading.ExceptHookArgs. * Add _PyErr_Display(): similar to PyErr_Display(), but accept a 'file' parameter. * Add _thread._excepthook(): C implementation of the exception hook calling _PyErr_Display(). * Add _thread._ExceptHookArgs: structseq type. * Add threading._invoke_excepthook_wrapper() which handles the gory details to ensure that everything remains alive during Python shutdown. * Add unit tests.
* bpo-32941: Add madvise() for mmap objects (GH-6172)Zackery Spytz2019-05-271-0/+118

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add a whole new documentation page: "Python Initialization Configuration" * PyWideStringList_Append() return type is now PyStatus, instead of int * PyInterpreterState_New() now calls PyConfig_Clear() if PyConfig_InitPythonConfig() fails. * Rename files: * Python/coreconfig.c => Python/initconfig.c * Include/cpython/coreconfig.h => Include/cpython/initconfig.h * Include/internal/: pycore_coreconfig.h => pycore_initconfig.h * Rename structures * _PyCoreConfig => PyConfig * _PyPreConfig => PyPreConfig * _PyInitError => PyStatus * _PyWstrList => PyWideStringList * Rename PyConfig fields: * use_module_search_paths => module_search_paths_set * module_search_path_env => pythonpath_env * Rename PyStatus field: _func => func * PyInterpreterState: rename core_config field to config * Rename macros and functions: * _PyCoreConfig_SetArgv() => PyConfig_SetBytesArgv() * _PyCoreConfig_SetWideArgv() => PyConfig_SetArgv() * _PyCoreConfig_DecodeLocale() => PyConfig_SetBytesString() * _PyInitError_Failed() => PyStatus_Exception() * _Py_INIT_ERROR_TYPE_xxx enums => _PyStatus_TYPE_xxx * _Py_UnixMain() => Py_BytesMain() * _Py_ExitInitError() => Py_ExitStatusException() * _Py_PreInitializeFromArgs() => Py_PreInitializeFromBytesArgs() * _Py_PreInitializeFromWideArgs() => Py_PreInitializeFromArgs() * _Py_PreInitialize() => Py_PreInitialize() * _Py_RunMain() => Py_RunMain() * _Py_InitializeFromConfig() => Py_InitializeFromConfig() * _Py_INIT_XXX() => _PyStatus_XXX() * _Py_INIT_FAILED() => _PyStatus_EXCEPTION() * Rename 'err' PyStatus variables to 'status' * Convert RUN_CODE() macro to config_run_code() static inline function * Remove functions: * _Py_InitializeFromArgs() * _Py_InitializeFromWideArgs() * _PyInterpreterState_GetCoreConfig()
* bpo-32528: Make asyncio.CancelledError a BaseException. (GH-13528)Yury Selivanov2019-05-271-7/+4
| | | | | | | | | | | | | | | This will address the common mistake many asyncio users make: an "except Exception" clause breaking Tasks cancellation. In addition to this change, we stop inheriting asyncio.TimeoutError and asyncio.InvalidStateError from their concurrent.futures.* counterparts. There's no point for these exceptions to share the inheritance chain. In 3.9 we'll focus on implementing supervisors and cancel scopes, which should allow better handling of all exceptions, including SystemExit and KeyboardInterrupt
* bpo-36829: Add _PyErr_WriteUnraisableMsg() (GH-13488)Victor Stinner2019-05-273-9/+19

| | | | | | | | | | | | | | | | * Fix a possible reference leak in _PyErr_Print() if exception is NULL. * PyErr_BadInternalCall(): replace PyErr_Format() with _PyErr_SetString(). * Add pycore_pyerrors.h header file. * New functions: * _PyErr_Clear() * _PyErr_Fetch() * _PyErr_Print() * _PyErr_Restore() * _PyErr_SetObject() * _PyErr_SetString() * Add 'tstate' parameter to _PyEval_AddPendingCall().
* bpo-37031: Fix PyOS_AfterFork_Child() (GH-13537)Victor Stinner2019-05-241-1/+1
| | | | | | | PyOS_AfterFork_Child(): _PyInterpreterState_DeleteExceptMain() must be called after _PyRuntimeState_ReInitThreads(). _PyRuntimeState_ReInitThreads() resets interpreters mutex after fork, mutex used by _PyInterpreterState_DeleteExceptMain().
* bpo-37031: Reuse _PyRuntime.main_thread in signalmodule.c (GH-13538)Victor Stinner2019-05-241-16/+16
| | | | | | | | | | Remove main_thread and main_interp variables from signalmodule.c: reuse _PyRuntime which already track the main thread and the main interpreter. * Remove #include <sys/types.h> which became useless: getpid() call has been removed. * Add runtime argument to is_main() * is_main() now gets the interpreter from runtime.
* 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-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.

Needs tests. * Speed up isqrt for n >= 2**64 as well; add extra tests. * Reduce number of test-cases to avoid dominating the run-time of test_math. * Don't perform unnecessary extra iterations when computing c_bit_length. * Abstract common uint64_t code out into a separate function. * Cleanup. * Add a missing Py_DECREF in an error branch. More cleanup. * Update Modules/mathmodule.c Add missing `static` declaration to helper function. Co-Authored-By: Serhiy Storchaka <storchaka@gmail.com> * Add missing backtick.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* 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

* 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.
