* [3.10] gh-91924: Fix __ltrace__ for non-UTF-8 stdout encoding (#93214)Victor Stinner2022-05-251-0/+2
| | | | | | | | | | Fix __ltrace__ debug feature if the stdout encoding is not UTF-8. If the stdout encoding is not UTF-8, the first call to lltrace_resume_frame() indirectly sets lltrace to 0 when calling unicode_check_encoding_errors() which calls encodings.search_function(). Add test_lltrace.test_lltrace() test.
* [3.10] bpo-46940: Don't override existing AttributeError suggestion ↵Pablo Galindo Salgado2022-03-071-3/+6
| | | | | | | | | | | | | | | information (GH-31710) (GH-31724) When an exception is created in a nested call to PyObject_GetAttr, any external calls will override the context information of the AttributeError that we have already placed in the most internal call. This will cause the suggestions we create to nor work properly as the attribute name and object that we will be using are the incorrect ones. To avoid this, we need to check first if these attributes are already set and bail out if that's the case..

| | | | | | | Add the Py_Is(x, y) function to test if the 'x' object is the 'y' object, the same as "x is y" in Python. Add also the Py_IsNone(), Py_IsTrue(), Py_IsFalse() functions to test if an object is, respectively, the None singleton, the True singleton or the False singleton.

* bpo-42990: Functions inherit current builtins (GH-24564)Victor Stinner2021-02-201-12/+16
| | | | | | | | | | | | | | | | | | | | 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-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-16/+15
| | | | | | | | | | | | | | | 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 Stinner2021-02-191-1/+1
| | | | | | | | 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-42990: Refactor _PyFrame_New_NoTrack() (GH-24566)Victor Stinner2021-02-181-3/+3
| | | | | | | | | | | | * 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-42296: On Windows, fix CTRL+C regression (GH-23257)Victor Stinner2020-11-131-5/+33
| | | | | | | | | | | On Windows, fix a regression in signal handling which prevented to interrupt a program using CTRL+C. The signal handler can be run in a thread different than the Python thread, in which case the test deciding if the thread can handle signals is wrong. On Windows, _PyEval_SignalReceived() now always sets eval_breaker to 1 since it cannot test _Py_ThreadCanHandleSignals(), and eval_frame_handle_pending() always calls _Py_ThreadCanHandleSignals() to recompute eval_breaker.

| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
