* bpo-28994: PyErr_NormalizeException() no longer use C stack for recursion. ↵Serhiy Storchaka2017-11-051-39/+33
| | | | | (#2035) MemoryError raised when normalizing a RecursionError raised during exception normalization now not always causes a fatal error.

* Move exc state to generator. Fixes bpo-25612 (#1773)Mark Shannon2017-10-221-10/+24
| | | Move exception state information from frame objects to coroutine (generator/thread) object where it belongs.
* bpo-31418: Fix an assertion failure in PyErr_WriteUnraisable() in case of an ↵Oren Milman2017-09-131-1/+1
| | | | exception with a bad __module__ attribute. (#3539)
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+1
| | | | | | | * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.

* | | Issue #28618: Make hot functions using __attribute__((hot))Victor Stinner2016-11-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Python is not compiled with PGO, the performance of Python on call_simple and call_method microbenchmarks depend highly on the code placement. In the worst case, the performance slowdown can be up to 70%. The GCC __attribute__((hot)) attribute helps to keep hot code close to reduce the risk of such major slowdown. This attribute is ignored when Python is compiled with PGO. The following functions are considered as hot according to statistics collected by perf record/perf report: * _PyEval_EvalFrameDefault() * call_function() * _PyFunction_FastCall() * PyFrame_New() * frame_dealloc() * PyErr_Occurred()
* | | Use PyThreadState_GET() in performance critical codeVictor Stinner2016-11-111-1/+1
|/ / | | | | | | | | It seems like _PyThreadState_UncheckedGet() is not inlined as expected, even when using gcc -O3.

* Add _PyThreadState_UncheckedGet()Victor Stinner2016-01-201-7/+1
| | | | | | | | | | | | | | | | | | | Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which gets the current thread state, but don't call Py_FatalError() if it is NULL. Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to no more expose complex and private atomic types. Atomic types depends on the compiler or can even depend on compiler options. The new function _PyThreadState_UncheckedGet() allows to get the variable value without having to care of the exact implementation of atomic types. Changes: * Replace direct usage of the _PyThreadState_Current variable with a call to _PyThreadState_UncheckedGet(). * In pystate.c, replace direct usage of the _PyThreadState_Current variable with the PyThreadState_GET() macro for readability. * Document also PyThreadState_Get() in pystate.h
