* bpo-32381: Rewrite PyErr_ProgramText() (GH-23700)Victor Stinner2020-12-081-5/+10
| | | PyErr_ProgramText() now calls PyErr_ProgramTextObject().
* bpo-42599: Remove useless PyModule_GetWarningsModule() (GH-23691)Hai Shi2020-12-081-3/+0
| | | | Removed PyModule_GetWarningsModule() which is useless due to the _warnings module was converted to a builtin module in 2.6.
* bpo-42500: Fix recursion in or after except (GH-23568)Mark Shannon2020-12-021-0/+3
| | | * Use counter, rather boolean state when handling soft overflows.
* bpo-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)Serhiy Storchaka2020-10-261-4/+5
| | | | | | | If PyDict_GetItemWithError is only used to check whether the key is in dict, it is better to use PyDict_Contains instead. And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can replace the combination.
* bpo-41991: Remove _PyObject_HasAttrId (GH-22629)Serhiy Storchaka2020-10-101-2/+17
| | | It can silence arbitrary exceptions.
* bpo-40985: Show correct SyntaxError text when last line has a LINECONT ↵Lysandros Nikolaou2020-06-161-4/+8
| | | | | | | | (GH-20888) When a file ends with a line that contains a line continuation character the text of the emitted SyntaxError is empty, contrary to the old parser, where the error text contained the text of the last line.
* Remove redundant var in PyErr_NewException() (GH-20850)Hai Shi2020-06-131-2/+0
|
* bpo-40826: Add _Py_EnsureTstateNotNULL() macro (GH-20571)Victor Stinner2020-06-011-1/+1
| | | | Add _Py_EnsureTstateNotNULL(tstate) macro: call Py_FatalError() if tstate is NULL, the error message contains the current function name.
* bpo-40696: Fix a hang that can arise after gen.throw() (GH-20287)Chris Jerdonek2020-05-221-9/+53
| | | | | | | | This updates _PyErr_ChainStackItem() to use _PyErr_SetObject() instead of _PyErr_ChainExceptions(). This prevents a hang in certain circumstances because _PyErr_SetObject() performs checks to prevent cycles in the exception context chain while _PyErr_ChainExceptions() doesn't.
* bpo-31033: Improve the traceback for cancelled asyncio tasks (GH-19951)Chris Jerdonek2020-05-181-0/+14
| | | | | When an asyncio.Task is cancelled, the exception traceback now starts with where the task was first interrupted. Previously, the traceback only had "depth one."
* bpo-29587: _PyErr_ChainExceptions() checks exception (GH-19902)Victor Stinner2020-05-051-1/+11
| | | | | | | | | | | | | | | | | | | _PyErr_ChainExceptions() now ensures that the first parameter is an exception type, as done by _PyErr_SetObject(). * The following function now check PyExceptionInstance_Check() in an assertion using a new _PyBaseExceptionObject_cast() helper function: * PyException_GetTraceback(), PyException_SetTraceback() * PyException_GetCause(), PyException_SetCause() * PyException_GetContext(), PyException_SetContext() * PyExceptionClass_Name() now checks PyExceptionClass_Check() with an assertion. * Remove XXX comment and add gi_exc_state variable to _gen_throw(). * Remove comment from test_generators
* bpo-40429: PyThreadState_GetFrame() returns a strong ref (GH-19781)Victor Stinner2020-04-291-1/+1
| | | | The PyThreadState_GetFrame() function now returns a strong reference to the frame.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-141-1/+1
|
* bpo-38644: Use _PySys_Audit(): pass tstate explicitly (GH-19183)Victor Stinner2020-03-271-1/+2
| | | Add the dependency to tstate more explicit.
* bpo-39573: Use Py_IS_TYPE() macro to check for types (GH-18809)Andy Lester2020-03-061-1/+1
| | | Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-39573: Finish converting to new Py_IS_TYPE() macro (GH-18601)Andy Lester2020-03-041-1/+1
|
* closes bpo-39630: Update pointers to string literals to be const char *. ↵Andy Lester2020-02-141-1/+1
| | | | (GH-18510)
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The bulk of this patch was generated automatically with: for name in \ PyObject_Vectorcall \ Py_TPFLAGS_HAVE_VECTORCALL \ PyObject_VectorcallMethod \ PyVectorcall_Function \ PyObject_CallOneArg \ PyObject_CallMethodNoArgs \ PyObject_CallMethodOneArg \ ; do echo $name git grep -lwz _$name | xargs -0 sed -i "s/\b_$name\b/$name/g" done old=_PyObject_FastCallDict new=PyObject_VectorcallDict git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g" and then cleaned up: - Revert changes to in docs & news - Revert changes to backcompat defines in headers - Nudge misaligned comments
* bpo-39487: Merge duplicated _Py_IDENTIFIER identifiers in C code (GH-18254)Hai Shi2020-01-301-3/+1
| | | Moving repetitive `_Py_IDENTIFIER` instances to a global location helps identify them more easily in regards to sub-interpreter support.
* bpo-39164: Fix compiler warning in PyErr_GetExcInfo() (GH-18010)Victor Stinner2020-01-151-1/+1
| | | The function has no return value.
* bpo-39164: Add private _PyErr_GetExcInfo() function (GH-17752)Julien Danjou2020-01-131-4/+10
| | | | | | This adds a new function named _PyErr_GetExcInfo() that is a variation of the original PyErr_GetExcInfo() taking a PyThreadState as its first argument. That function allows to retrieve the exceptions information of any Python thread -- not only the current one.
* bpo-38920: Add audit hooks for when sys.excepthook and sys.unraisable hooks ↵Steve Dower2019-11-281-30/+40
| | | | | are invoked (GH-17392) Also fixes some potential segfaults in unraisable hook handling.
* bpo-38733: PyErr_Occurred() caller must hold the GIL (GH-17080)Victor Stinner2019-11-071-0/+3
| | | | | | | | | | | bpo-3605, bpo-38733: Optimize _PyErr_Occurred(): remove "tstate == NULL" test. Py_FatalError() no longer calls PyErr_Occurred() if called without holding the GIL. So PyErr_Occurred() no longer has to support tstate==NULL case. _Py_CheckFunctionResult(): use directly _PyErr_Occurred() to avoid explicit "!= NULL" test.
* bpo-38644: Pass tstate to _Py_CheckFunctionResult() (GH-17050)Victor Stinner2019-11-051-0/+15
| | | | | * Add tstate parameter to _Py_CheckFunctionResult() * Add _PyErr_FormatFromCauseTstate() * Replace PyErr_XXX(...) with _PyErr_XXX(state, ...)
* bpo-37337: Add _PyObject_CallMethodNoArgs() (GH-14267)Jeroen Demeyer2019-07-081-1/+1
|
* bpo-37483: add _PyObject_CallOneArg() function (#14558)Jeroen Demeyer2019-07-041-3/+2
|
* bpo-36710: Pass explicitly tstate in sysmodule.c (GH-14060)Victor Stinner2019-06-131-2/+8
| | | | | | | | * Replace global var Py_VerboseFlag with interp->config.verbose. * Add _PyErr_NoMemory(tstate) function. * Add tstate parameter to _PyEval_SetCoroutineOriginTrackingDepth() and move the function to the internal API. * Replace _PySys_InitMain(runtime, interp) with _PySys_InitMain(runtime, tstate).
* bpo-36829: sys.excepthook and sys.unraisablehook flush (GH-13620)Victor Stinner2019-05-281-0/+9
| | | | | | | sys.excepthook() and sys.unraisablehook() now explicitly flush the file (usually sys.stderr). If file.flush() fails, sys.excepthook() silently ignores the error, whereas sys.unraisablehook() logs the new exception.
* bpo-36763: Implement the PEP 587 (GH-13592)Victor Stinner2019-05-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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-36829: Add _PyErr_WriteUnraisableMsg() (GH-13488)Victor Stinner2019-05-271-13/+71
| | | | | * sys.unraisablehook: add 'err_msg' field to UnraisableHookArgs. * Use _PyErr_WriteUnraisableMsg() in _ctypes _DictRemover_call() and gc delete_garbage().
* bpo-36710: Add tstate parameter in ceval.c (GH-13547)Victor Stinner2019-05-241-32/+60
| | | | | | | | | | | | | | | | * 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-36710: Add tstate parameter in errors.c (GH-13540)Victor Stinner2019-05-241-116/+230
| | | | Add 'PyThreadState *tstate' parameter to errors.c functions to avoid relying on global variables (indirectly on _PyRuntime).
* bpo-36829: PyErr_WriteUnraisable() normalizes exception (GH-13507)Victor Stinner2019-05-221-1/+21
| | | | | | PyErr_WriteUnraisable() now creates a traceback object if there is no current traceback. Moreover, call PyErr_NormalizeException() and PyException_SetTraceback() to normalize the exception value. Ignore silently any error.
* bpo-36829: Add sys.unraisablehook() (GH-13187)Victor Stinner2019-05-221-48/+230
| | | | | | | | | | | | | | | | | | | 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-35459: Use PyDict_GetItemWithError() instead of PyDict_GetItem(). (GH-11112)Serhiy Storchaka2019-02-251-2/+6

* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".

| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* bpo-31091: Remove dead code in PyErr_GivenExceptionMatches(). (#2963)scoder2017-07-311-13/+1
| | | According to the comment, there was previously a call to PyObject_IsSubclass() involved which could fail, but since it was replaced with a call to PyType_IsSubtype(), it can no longer fail.
