* bpo-43244: Add pycore_ast.h header file (GH-24908)Victor Stinner2021-03-172-8/+25
| | | | | | | | Move _PyAST_GetDocString() and _PyAST_ExprAsUnicode() functions the internal C API: from Include/ast.h to a new Include/internal/pycore_ast.h header file. Don't export these functions anymore: replace PyAPI_FUNC() with extern. Remove also unused includes.
* bpo-43244: Rename pycore_ast.h to pycore_ast_state.h (GH-24907)Victor Stinner2021-03-172-4/+4

* bpo-43356: Allow passing a signal number to interrupt_main() (GH-24755)Antoine Pitrou2021-03-112-0/+19
| | | | Also introduce a new C API ``PyErr_SetInterruptEx(int signum)``.
* bpo-43311: Create GIL autoTSSkey ealier (GH-24819)Victor Stinner2021-03-101-1/+4
| | | | | | At Python startup, call _PyGILState_Init() before PyInterpreterState_New() which calls _PyThreadState_GET(). When Python is built using --with-experimental-isolated-subinterpreters, _PyThreadState_GET() uses autoTSSkey.
* bpo-37146: Move _PyEval_DeactivateOpCache() to the internal C API (GH-24786)Victor Stinner2021-03-082-2/+2
| | | Don't export the symbol anymore.
* bpo-43271: Re-enable ceval.c optimizations for Windows debug builds (GH-24739)db3l2021-03-041-1/+2
| | | | | | Partially reverts commit b74396c3167cc780f01309148db02709bc37b432 The optimizations are necessary to prevent the interpreter from crashing in a number of tests involving recursion.

* bpo-43277: Add PySet_CheckExact to the C-API (GH-24598)Pablo Galindo2021-02-201-3/+6
| | | For some mysterious reason we have PySet_Check, PyFrozenSet_Check, PyAnySet_Check, PyAnySet_CheckExact and PyFrozenSet_CheckExact but no PySet_CheckExact.
* bpo-42990: Functions inherit current builtins (GH-24564)Victor Stinner2021-02-201-1/+4
| | | | | | | | | | | | | | | | | | | | The types.FunctionType constructor now inherits the current builtins if the globals dictionary has no "__builtins__" key, rather than using {"None": None} as builtins: same behavior as eval() and exec() functions. Defining a function with "def function(...): ..." in Python is not affected, globals cannot be overriden with this syntax: it also inherits the current builtins. PyFrame_New(), PyEval_EvalCode(), PyEval_EvalCodeEx(), PyFunction_New() and PyFunction_NewWithQualName() now inherits the current builtins namespace if the globals dictionary has no "__builtins__" key. * Add _PyEval_GetBuiltins() function. * _PyEval_BuiltinsFromGlobals() now uses _PyEval_GetBuiltins() if builtins cannot be found in globals. * Add tstate parameter to _PyEval_BuiltinsFromGlobals().
* bpo-35134: Move non-limited C API files to Include/cpython/ (GH-24561)Nicholas Sim2021-02-196-5/+5
| | | | | | Include/{odictobject.h,parser_interface.h,picklebufobject.h,pydebug.h,pyfpe.h} into Include/cpython/. Parser: peg_api: include Python.h instead of parser_interface.h.
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-195-36/+36
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-43270: Remove private _PyErr_OCCURRED() macro (GH-24579)Victor Stinner2021-02-191-6/+0
| | | | | | | | Remove the private _PyErr_OCCURRED() macro: use the public PyErr_Occurred() function instead. CPython internals must use the internal _PyErr_Occurred(tstate) function instead: it is the most efficient way to check if an exception was raised.
* bpo-43268: _Py_IsMainInterpreter() now expects interp (GH-24577)Victor Stinner2021-02-191-2/+2
| | | | The _Py_IsMainInterpreter() function now expects interp rather than tstate.
* bpo-40522: Replace PyThreadState_GET() with PyThreadState_Get() (GH-24575)Victor Stinner2021-02-192-5/+5
| | | | | Use directly the PyThreadState_Get() function in public header files, since PyThreadState_GET() macro is just an alias to it in pratice in these files.
* bpo-43268: Replace _PyThreadState_GET() with _PyInterpreterState_GET() ↵Victor Stinner2021-02-192-10/+7
| | | | | | | | | | | (GH-24576) Replace _PyThreadState_GET() with _PyInterpreterState_GET() in functions which only need the current interpreter, but don't need the current Python thread state. Replace also _PyThreadState_UncheckedGet() with _PyThreadState_GET() in faulthandler.c, since _PyThreadState_UncheckedGet() is just an alias to _PyThreadState_GET() in practice.
* bpo-42990: Refactor _PyFrame_New_NoTrack() (GH-24566)Victor Stinner2021-02-182-3/+4
| | | | | | | | | | | | * Refactor _PyFrame_New_NoTrack() and PyFunction_NewWithQualName() code. * PyFrame_New() checks for _PyEval_BuiltinsFromGlobals() failure. * Fix a ref leak in _PyEval_BuiltinsFromGlobals() error path. * Complete PyFunction_GetModule() documentation: it returns a borrowed reference and it can return NULL. * Move _PyEval_BuiltinsFromGlobals() definition to the internal C API. * PyFunction_NewWithQualName() uses _Py_IDENTIFIER() API for the "__name__" string to make it compatible with subinterpreters.
* bpo-35134: Move Include/{pyarena.h,pyctype.h} to Include/cpython/ (GH-24550)Nicholas Sim2021-02-173-2/+2
| | | | Move non-limited C API headers pyarena.h and pyctype.h into Include/cpython/ directory.
* bpo-40170: Always define PyExceptionClass_Name() as a function (GH-24553)Erlend Egeberg Aasland2021-02-171-4/+0

* bpo-35134, Include: Move pytime.h to cpython/pytime.h (GH-23988)Nicholas Sim2021-02-162-4/+1
| | | | This change is backward compatible since C extension modules must not include "pytime.h" directly, but only include "Python.h".

Break into make-frame, and eval-frame parts. * Simplify function vector call using new _PyEval_Vector. * Remove unused internal functions: _PyEval_EvalCodeWithName and _PyEval_EvalCode. * Don't use legacy function PyEval_EvalCodeEx.

* bpo-42979: Enhance abstract.c assertions checking slot result (GH-24352)Victor Stinner2021-01-272-1/+7
| | | | | | | | * bpo-42979: Enhance abstract.c assertions checking slot result Add _Py_CheckSlotResult() function which fails with a fatal error if a slot function succeeded with an exception set or failed with no exception set: write the slot name, the type name and the current exception (if an exception is set).

* bpo-42923: Dump extension modules on fatal error (GH-24207)Victor Stinner2021-01-182-0/+8
| | | | | | | The Py_FatalError() function and the faulthandler module now dump the list of extension modules on a fatal error. Add _Py_DumpExtensionModules() and _PyModule_IsExtension() internal functions.
* bpo-42923: Py_FatalError() avoids fprintf() (GH-24242)Victor Stinner2021-01-181-7/+3

| | | | | | | | Fix the _PyUnicode_FromId() function (_Py_IDENTIFIER(var) API) when Py_Initialize() / Py_Finalize() is called multiple times: preserve _PyRuntime.unicode_ids.next_index value. Use _PyRuntimeState_INIT macro instead memset(0) to reset _PyRuntimeState members to zero.

* bpo-40521: Per-interpreter interned strings (GH-20085)Victor Stinner2020-12-261-0/+11
| | | | | | | | | | | Make the Unicode dictionary of interned strings compatible with subinterpreters. Remove the INTERN_NAME_STRINGS macro in typeobject.c: names are always now interned (even if EXPERIMENTAL_ISOLATED_SUBINTERPRETERS macro is defined). _PyUnicode_ClearInterned() now uses PyDict_Next() to no longer allocate memory, to ensure that the interned dictionary is cleared.
* bpo-42745: Make the type cache per-interpreter (GH-23947)Victor Stinner2020-12-263-1/+26
| | | | | | | | | | | Make the type attribute lookup cache per-interpreter. Add private _PyType_InitCache() function, called by PyInterpreterState_New(). Continue to share next_version_tag between interpreters, since static types are still shared by interpreters. Remove MCACHE macro: the cache is no longer disabled if the EXPERIMENTAL_ISOLATED_SUBINTERPRETERS macro is defined.
* bpo-39465: Fix _PyUnicode_FromId() for subinterpreters (GH-20058)Victor Stinner2020-12-253-3/+18
| | | | | | | | | | | | | | | | | Make _PyUnicode_FromId() function compatible with subinterpreters. Each interpreter now has an array of identifier objects (interned strings decoded from UTF-8). * Add PyInterpreterState.unicode.identifiers: array of identifiers objects. * Add _PyRuntimeState.unicode_ids used to allocate unique indexes to _Py_Identifier. * Rewrite the _Py_Identifier structure. Microbenchmark on _PyUnicode_FromId(&PyId_a) with _Py_IDENTIFIER(a): [ref] 2.42 ns +- 0.00 ns -> [atomic] 3.39 ns +- 0.00 ns: 1.40x slower This change adds 1 ns per _PyUnicode_FromId() call in average.
