* bpo-38650: Constify PyStructSequence_UnnamedField. (GH-17005)Serhiy Storchaka2019-11-161-1/+1
| | | | Make it a constant and referring to a constant string.
* bpo-38644: Cleanup ceval.h (GH-17185)Victor Stinner2019-11-162-36/+25
| | | | Move CPython API (Py_LIMITED_API macro not defined) from ceval.h to cpython/ceval.h
* bpo-38644: Add _PyEval_EvalCode() (GH-17183)Victor Stinner2019-11-161-0/+10
| | | _PyFunction_Vectorcall() now pass tstate to function calls.
* bpo-38644: Add _PyObject_Call() (GH-17089)Victor Stinner2019-11-142-10/+46
| | | | | | | | | | * Add pycore_call.h internal header file. * Add _PyObject_Call(): PyObject_Call() with tstate * Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate * Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict() with tstate * _PyObject_Call_Prepend() now takes tstate * Replace _PyObject_FastCall() calls with _PyObject_VectorcallTstate() calls
* bpo-38644: Add _PyEval_EvalFrame() with tstate (GH-17131)Victor Stinner2019-11-141-0/+9
| | | | Add _PyEval_EvalFrame() static inline function to get eval_frame from tstate->interp.
* bpo-38644: Add _PyObject_VectorcallTstate() (GH-17052)Victor Stinner2019-11-081-4/+14
| | | | | * Add _PyObject_VectorcallTstate() function: similar to _PyObject_Vectorcall(), but with tstate parameter * Add tstate parameter to _PyObject_MakeTpCall()
* bpo-38733: PyErr_Occurred() caller must hold the GIL (GH-17080)Victor Stinner2019-11-071-1/+2
| | | | | | | | | | | 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-36876: Moved Parser/listnode.c statics to interpreter state. (GH-16328)Vinay Sajip2019-11-071-0/+9
|
* bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)Jeroen Demeyer2019-11-051-0/+1
| | | | | | | | | | | | Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code. CC @vstinner @encukou https://bugs.python.org/issue37645 Automerge-Triggered-By: @encukou
* bpo-38644: Pass tstate to _Py_CheckFunctionResult() (GH-17050)Victor Stinner2019-11-052-4/+14
| | | | | * Add tstate parameter to _Py_CheckFunctionResult() * Add _PyErr_FormatFromCauseTstate() * Replace PyErr_XXX(...) with _PyErr_XXX(state, ...)
* bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)Victor Stinner2019-11-041-14/+31
| | | | | | | | | | | | | * Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which require a tstate argument. * Pass tstate to _Py_MakeRecCheck() and _Py_CheckRecursiveCall(). * Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros to static inline functions. _PyThreadState_GET() is the most efficient way to get the tstate, and so using it with _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() should be a little bit more efficient than using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use the "slower" PyThreadState_GET().
* bpo-38644: Add Py_EnterRecursiveCall() to the limited API (GH-17046)Victor Stinner2019-11-042-35/+58
| | | | | | | | | | Provide Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() as regular functions for the limited API. Previously, there were defined as macros, but these macros didn't work with the limited API which cannot access PyThreadState.recursion_depth field. Remove _Py_CheckRecursionLimit from the stable ABI. Add Include/cpython/ceval.h header file.
* bpo-38600: Change the mark up of NULL in the C API documentation. (GH-16950)Serhiy Storchaka2019-10-301-3/+3
| | | | Replace all *NULL* with ``NULL``.
* bpo-38465: Convert the type of exports counters to Py_ssize_t. (GH-16746)Hai Shi2019-10-211-5/+4
|
* bpo-11410: Standardize and use symbol visibility attributes across POSIX and ↵Vinay Sajip2019-10-152-11/+43
| | | | Windows. (GH-16347)
* bpo-38392: Only declare visit_validate() if Py_DEBUG is defined (GH-16689)Victor Stinner2019-10-101-1/+1
| | | | | bpo-38392, bpo-38426: Fix a compiler warning in gcmodule.c. Fix also a typo in PYMEM_DEADBYTE macro comment.
* bpo-36389: Fix _PyBytesWriter in release mode (GH-16624)Victor Stinner2019-10-071-0/+15
| | | | Fix _PyBytesWriter API when Python is built in release mode with assertions.
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-074-15/+11
| | | | | | | | | | | | | | | | | | | | | bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end.
* bpo-38353: getpath.c: allocates strings on the heap (GH-16585)Victor Stinner2019-10-041-3/+2
| | | | | | | | | | | * _Py_FindEnvConfigValue() now returns a string allocated by PyMem_RawMalloc(). * calculate_init() now decodes VPATH macro. * Add calculate_open_pyenv() function. * Add substring() and joinpath2() functions. * Fix add_exe_suffix() And a few cleanup changes.
* bpo-38266: Revert bpo-37878: Make PyThreadState_DeleteCurrent() Internal ↵Joannah Nanjekye2019-10-041-0/+1
| | | | | (GH-16558) Revert the removal of PyThreadState_DeleteCurrent() with documentation.
* bpo-38353: Fix compiler warning in internal headers (GH-16573)Victor Stinner2019-10-043-16/+16
| | | | Replace "_PyRuntimeState" with "struct pyruntimestate" to avoid a warning on typedef re-definition.
* bpo-38353: Fix compiler warning in pycore_initconfig.h (GH-16570)Victor Stinner2019-10-031-2/+2
| | | | Replace "_PyRuntimeState" with "struct pyruntimestate" to avoid a warning on typedef re-definition.
* bpo-38353: Cleanup includes in the internal C API (GH-16548)Victor Stinner2019-10-0212-29/+21
| | | | Use forward declaration of types to avoid includes in the internal C API. Add also comment to justify other includes.
* bpo-38304: PyConfig_InitPythonConfig() cannot fail anymore (GH-16509)Victor Stinner2019-10-012-3/+3
| | | | PyConfig_InitPythonConfig() and PyConfig_InitIsolatedConfig() no longer return PyStatus: they cannot fail anymore.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-012-12/+4
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)
* bpo-30773: Fix ag_running; prohibit running athrow/asend/aclose in parallel ↵Yury Selivanov2019-09-301-0/+2
| | | | (#7468)
* bpo-38317: Fix PyConfig.warnoptions priority (GH-16478)Victor Stinner2019-09-293-3/+6
| | | | | | | | | Fix warnings options priority: PyConfig.warnoptions has the highest priority, as stated in the PEP 587. * Document options order in PyConfig.warnoptions documentation. * Make PyWideStringList_INIT macro private: replace "Py" prefix with "_Py". * test_embed: add test_init_warnoptions().
* bpo-38304: Add PyConfig.struct_size (GH-16451)Victor Stinner2019-09-282-13/+16
| | | | | | | | | | | | | | | | | Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
* bpo-38234: Py_Initialize() sets global path configuration (GH-16421)Victor Stinner2019-09-261-1/+1
| | | | | | * Py_InitializeFromConfig() now writes PyConfig path configuration to the global path configuration (_Py_path_config). * Add test_embed.test_get_pathconfig(). * Fix typo in _PyWideStringList_Join().
* bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)Victor Stinner2019-09-261-4/+11
| | | | | | | | | | | | * Add test_embed.test_init_setpath_config(): test Py_SetPath() with PyConfig. * test_init_setpath() and test_init_setpythonhome() no longer call Py_SetProgramName(), but use the default program name. * _PyPathConfig: isolated, site_import and base_executable fields are now only available on Windows. * If executable is set explicitly in the configuration, ignore calculated base_executable: _PyConfig_InitPathConfig() copies executable to base_executable. * Complete path config documentation.
* closes bpo-38253: Fix typo of Py_SET_ERANGE_IF_OVERFLOW in pyport.h. (GH-16230)Hai Shi2019-09-241-1/+1
|
* bpo-38236: Dump path config at first import error (GH-16300)Victor Stinner2019-09-231-0/+1
| | | | Python now dumps path configuration if it fails to import the Python codecs of the filesystem and stdio encodings.
* bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)Victor Stinner2019-09-202-6/+6
| | | | | | | | | The DLL path is not computed from any user configuration and cannot be configured by PyConfig. Instead, add a new _Py_dll_path global variable. Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init(). Py_Initialize() now longer sets the "global path configuration", but only initialize _Py_dll_path.
* bpo-38205: Py_UNREACHABLE() calls Py_FatalError() (GH-16290)Victor Stinner2019-09-201-23/+18
|
* Fix _PyTraceMalloc_Fini() definition (GH-16259)Victor Stinner2019-09-181-1/+1
| | | The function return type is void, not int.
* bpo-38070: Add _PyRuntimeState.preinitializing (GH-16245)Victor Stinner2019-09-171-3/+8
| | | | | | Add _PyRuntimeState.preinitializing field: set to 1 while Py_PreInitialize() is running. _PyRuntimeState: rename also pre_initialized field to preinitialized.
* bpo-38005: Fixed comparing and creating of InterpreterID and ChannelID. ↵Serhiy Storchaka2019-09-131-2/+0
| | | | | | | | | | | | | (GH-15652) * Fix a crash in comparing with float (and maybe other crashes). * They are now never equal to strings and non-integer numbers. * Comparison with a large number no longer raises OverflowError. * Arbitrary exceptions no longer silenced in constructors and comparisons. * TypeError raised in the constructor contains now the name of the type. * Accept only ChannelID and int-like objects in channel functions. * Accept only InterpreterId, int-like objects and str in the InterpreterId constructor. * Accept int-like objects, not just int in interpreter related functions.
* Cut disused recode_encoding logic in _PyBytes_DecodeEscape. (GH-16013)Greg Price2019-09-122-4/+2
| | | | | | | | | | | | | | | | | | | | | All call sites pass NULL for `recode_encoding`, so this path is completely untested. That's been true since before Python 3.0. It adds significant complexity to this logic, so it's best to take it out. All call sites now have a literal NULL, and that's been true since commit 768921cf3 eliminated a conditional (`foo ? bar : NULL`) at the call site in Python/ast.c where we're parsing a bytes literal. But even before then, that condition `foo` had been a constant since unadorned string literals started meaning Unicode, in commit 572dbf8f1 aka v3.0a1~1035 . The `unicode` parameter is already unused, so mark it as unused too. The code that acted on it was also taken out before Python 3.0, in commit 8d30cc014 aka v3.0a1~1031 . The function (PyBytes_DecodeEscape) is exposed in the API, but it's never been documented.
* Enhance Py_UNREACHABLE macro (GH-16032)Zachary Ware2019-09-121-0/+26
|
* bpo-21120: Exclude Python-ast.h, ast.h and asdl.h from the limited API (#14634)Zackery Spytz2019-09-123-4/+6
| | | | The PyArena type is not part of the limited API, so these headers shouldn't be part of it either.
* bpo-37151: remove special case for PyCFunction from PyObject_Call (GH-14684)Jeroen Demeyer2019-09-111-1/+1
| | | | | | | bpo-37151: remove special case for PyCFunction from PyObject_Call Alse, make the undocumented function PyCFunction_Call an alias of PyObject_Call and deprecate it.
* bpo-15088 : Remove PyGen_NeedsFinalizing() (GH-15702)Joannah Nanjekye2019-09-061-1/+0
| | | | | Remove PyGen_NeedsFinalizing(): it was not documented, tested or used anywhere within CPython after the implementation of PEP 442.
* bpo-37878: Remove PyThreadState_DeleteCurrent() function (GH-15315)Joannah Nanjekye2019-09-052-1/+2
| | | | | | | * Rename PyThreadState_DeleteCurrent() to _PyThreadState_DeleteCurrent() * Move it to the internal C API Co-Authored-By: Carol Willing <carolcode@willingconsulting.com>
* bpo-37781: use "z" for PY_FORMAT_SIZE_T (GH-15156)Inada Naoki2019-08-301-13/+6
| | | MSVC 2015 supports %zd / %zu. "z" is portable enough nowadays.
* Fix typos mostly in comments, docs and test names (GH-15209)Min ho Kim2019-08-301-1/+1
|
* bpo-37034: Display argument name on errors with keyword arguments with ↵Rémi Lapeyre2019-08-291-1/+1
| | | | Argument Clinic. (GH-13593)
* bpo-36763: Make Py_BytesMain() public (GH-15532)Victor Stinner2019-08-262-2/+2
| | | | Declare Py_BytesMain() in Include/pylifecycle.h, rather in Include/internal/pycore_pylifecycle.h.
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-12/+13
| | | | | For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.
* bpo-37757: Disallow PEP 572 cases that expose implementation details (GH-15131)Nick Coghlan2019-08-252-1/+3
| | | | | | | | | | | | | | | - drop TargetScopeError in favour of raising SyntaxError directly as per the updated PEP 572 - comprehension iteration variables are explicitly local, but named expression targets in comprehensions are nonlocal or global. Raise SyntaxError as specified in PEP 572 - named expression targets in the outermost iterable of a comprehension have an ambiguous target scope. Avoid resolving that question now by raising SyntaxError. PEP 572 originally required this only for cases where the bound name conflicts with the iteration variable in the comprehension, but CPython can't easily restrict the exception to that case (as it doesn't know the target variable names when visiting the outermost iterator expression)
* bpo-34880: Add the LOAD_ASSERTION_ERROR opcode. (GH-15073)Zackery Spytz2019-08-251-0/+1
| | | | Fix assert statement misbehavior if AssertionError is shadowed.
