| | | | | | | | | | | | | | | | | | | * Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place. * Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches * _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms. * _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches * _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup * _Py_Quicken is renamed to _PyCode_Quicken * _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview). * Do not emit unused nonzero opargs anymore in the compiler.

| | | | Remove the private undocumented function _PyEval_CallTracing() from the C API. Call the public sys.call_tracing() function instead.

| | | | | | | | | | | | | | | Remove the private undocumented function _PyEval_GetCoroutineOriginTrackingDepth() from the C API. Call the public sys.get_coroutine_origin_tracking_depth() function instead. Change the internal function _PyEval_SetCoroutineOriginTrackingDepth(): * Remove the 'tstate' parameter; * Add return value and raises an exception if depth is negative; * No longer export the function: call the public sys.set_coroutine_origin_tracking_depth() function instead. Uniformize also function declarations in pycore_ceval.h.
* Use low bit of LOAD_GLOBAL's oparg to indicate whether it should push an ↵Mark Shannon2022-03-171-5/+13
| | | | additional NULL. (GH-31933)

|
* bpo-46940: Don't override existing AttributeError suggestion information ↵Pablo Galindo Salgado2022-03-071-3/+6
| | | | | | | | | | | | (GH-31710) 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.
