* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* Use calloc-based functions, not malloc. (GH-19152)Andy Lester2020-03-251-2/+1
|
* bpo-39947: Add PyThreadState_GetInterpreter() (GH-18981)Victor Stinner2020-03-131-3/+3
| | | | Add PyThreadState_GetInterpreter(tstate): get the interpreter of a Python thread state.
* bpo-38631: Add _Py_NO_RETURN to functions calling Py_FatalError() (GH-18278)Victor Stinner2020-01-301-15/+1
| | | | | | | | | Add _Py_NO_RETURN to functions calling Py_FatalError(): * _PyObject_AssertFailed() * dummy_dealloc() * faulthandler_fatal_error_thread() * none_dealloc() * notimplemented_dealloc()
* bpo-38965: Fix faulthandler._stack_overflow() on GCC 10 (GH-17467)Victor Stinner2019-12-041-10/+6
| | | | Use the "volatile" keyword to prevent tail call optimization on any compiler, rather than relying on compiler specific pragma.
* bpo-38823: Fix refleaks in faulthandler init error path on Windows (GH-17250)Brandt Bucher2019-11-191-10/+21
|
* bpo-38203: faulthandler.dump_traceback_later() is always available (GH-16249)Victor Stinner2019-09-181-17/+0
| | | | dump_traceback_later() and cancel_dump_traceback_later() functions of the faulthandler module are always available since Python 3.7.
* bpo-37933: Fix faulthandler.cancel_dump_traceback_later() (GH-15440)Thomas A Caswell2019-08-291-0/+5
| | | | Fix faulthandler.cancel_dump_traceback_later() call if cancel_dump_traceback_later() was not called previously.
* bpo-37851: faulthandler allocates its stack on demand (GH-15358)Victor Stinner2019-08-211-48/+98
| | | | | | | | | | | | | | | | | | The faulthandler module no longer allocates its alternative stack at Python startup. Now the stack is only allocated at the first faulthandler usage. faulthandler no longer ignores memory allocation failure when allocating the stack. sigaltstack() failure now raises an OSError exception, rather than being ignored. The alternative stack is no longer used if sigaction() is not available. In practice, sigaltstack() should only be available when sigaction() is avaialble, so this change should have no effect in practice. faulthandler.dump_traceback_later() internal locks are now only allocated at the first dump_traceback_later() call, rather than always being allocated at Python startup.
* bpo-21131: Fix faulthandler.register(chain=True) stack (GH-15276)Victor Stinner2019-08-141-1/+5
| | | | | | faulthandler now allocates a dedicated stack of SIGSTKSZ*2 bytes, instead of just SIGSTKSZ bytes. Calling the previous signal handler in faulthandler signal handler uses more than SIGSTKSZ bytes of stack memory on some platforms.
* bpo-37337: Add _PyObject_CallMethodNoArgs() (GH-14267)Jeroen Demeyer2019-07-081-3/+3
|
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-35134: Split traceback.h header (GH-13430)Victor Stinner2019-05-191-0/+1
| | | | Add new Include/cpython/traceback.h and Include/internal/traceback.h header files.
* bpo-36763: Add _PyInitError functions (GH-13395)Victor Stinner2019-05-171-0/+1
| | | | | | | | | | | | | | | * 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.
* bpo-36856: Handle possible overflow in faulthandler_stack_overflow (GH-13205)Xi Ruoyao2019-05-111-4/+17
|
* bpo-36734: Fix compilation of faulthandler.c on HP-UX (GH-12970)Victor Stinner2019-04-301-1/+2
| | | Initialize "stack_t current_stack" to zero using memset().
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-271-5/+5
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-121-1/+1
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-8/+9
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32297: Few misspellings found in Python source code comments. (#4803)Mike2017-12-141-1/+1
| | | | | | | | * Fix multiple typos in code comments * Add spacing in comments (test_logging.py, test_math.py) * Fix spaces at the beginning of comments in test_logging.py
* bpo-32252: Fix faulthandler_suppress_crash_report() (#4794)Victor Stinner2017-12-111-1/+1
| | | | Fix faulthandler_suppress_crash_report() used to prevent core dump files when testing crashes. getrlimit() returns zero on success.
* bpo-32030: Enhance Py_Main() (#4412)Victor Stinner2017-11-161-34/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse more env vars in Py_Main(): * Add more options to _PyCoreConfig: * faulthandler * tracemalloc * importtime * Move code to parse environment variables from _Py_InitializeCore() to Py_Main(). This change fixes a regression from Python 3.6: PYTHONUNBUFFERED is now read before calling pymain_init_stdio(). * _PyFaulthandler_Init() and _PyTraceMalloc_Init() now take an argument to decide if the module has to be enabled at startup. * tracemalloc_start() is now responsible to check the maximum number of frames. Other changes: * Cleanup Py_Main(): * Rename some pymain_xxx() subfunctions * Add pymain_run_python() subfunction * Cleanup Py_NewInterpreter() * _PyInterpreterState_Enable() now reports failure * init_hash_secret() now considers pyurandom() failure as an "user error": don't fail with abort(). * pymain_optlist_append() and pymain_strdup() now sets err on memory allocation failure.
* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-32/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
* faulthandler: use _PyTime_t rather than double for timeout (#4139)Victor Stinner2017-10-271-20/+31
| | | | | | | | | | | | | | | | | Use the _PyTime_t type rather than double for the faulthandler timeout in dump_traceback_later(). This change should fix the following Coverity warning: CID 1420311: Incorrect expression (UNINTENDED_INTEGER_DIVISION) Dividing integer expressions "9223372036854775807LL" and "1000LL", and then converting the integer quotient to type "double". Any remainder, or fractional part of the quotient, is ignored. if ((timeout * 1e6) >= (double) PY_TIMEOUT_MAX) { The warning comes from (double)PY_TIMEOUT_MAX with: #define PY_TIMEOUT_MAX (PY_LLONG_MAX / 1000)
* bpo-31701: faulthandler: ignore MSC and COM Windows exception (#3929)Victor Stinner2017-10-091-3/+19
| | | | | | bpo-31701: On Windows, faulthandler.enable() now ignores MSC and COM exceptions.
* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-061-1/+1
| | | | | | | | | See PEP 539 for details. Highlights of changes: - Add Thread Specific Storage (TSS) API - Document the Thread Local Storage (TLS) API as deprecated - Update code that used TLS API to use TSS API
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-11/+1
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.

Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h
