* Issue #28999: Use Py_RETURN_NONE, Py_RETURN_TRUE and Py_RETURN_FALSE whereverSerhiy Storchaka2017-01-231-2/+1

* Backed out changeset 99c34e47348bVictor Stinner2016-12-091-1/+1
| | | | The change broke test_gdb.
* Inline PyEval_EvalFrameEx() in callersVictor Stinner2016-12-091-1/+1
| | | | | | | | The PEP 523 modified PyEval_EvalFrameEx(): it's now an indirection to interp->eval_frame(). Inline the call in performance critical code. Leave PyEval_EvalFrame() unchanged, this function is only kept for backward compatibility.
* Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-051-1/+1
| | | | | | | | | | | 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.
* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-2/+2
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunction() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | | | | Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-2/+2
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _PyGen_Finalize() checks that gen->gi_code is not NULL before it accesses the flags of the code object. This means that the flag could be NULL. It passes down the generatore to gen_close() and gen_send_ex(). gen_send_ex() did not check for gen->gi_code != NULL. CID 1297900

* Issue #24400: Introduce a distinct type for 'async def' coroutines.Yury Selivanov2015-06-221-57/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary of changes: 1. Coroutines now have a distinct, separate from generators type at the C level: PyGen_Type, and a new typedef PyCoroObject. PyCoroObject shares the initial segment of struct layout with PyGenObject, making it possible to reuse existing generators machinery. The new type is exposed as 'types.CoroutineType'. As a consequence of having a new type, CO_GENERATOR flag is no longer applied to coroutines. 2. Having a separate type for coroutines made it possible to add an __await__ method to the type. Although it is not used by the interpreter (see details on that below), it makes coroutines naturally (without using __instancecheck__) conform to collections.abc.Coroutine and collections.abc.Awaitable ABCs. [The __instancecheck__ is still used for generator-based coroutines, as we don't want to add __await__ for generators.] 3. Add new opcode: GET_YIELD_FROM_ITER. The opcode is needed to allow passing native coroutines to the YIELD_FROM opcode. Before this change, 'yield from o' expression was compiled to: (o) GET_ITER LOAD_CONST YIELD_FROM Now, we use GET_YIELD_FROM_ITER instead of GET_ITER. The reason for adding a new opcode is that GET_ITER is used in some contexts (such as 'for .. in' loops) where passing a coroutine object is invalid. 4. Add two new introspection functions to the inspec module: getcoroutinestate(c) and getcoroutinelocals(c). 5. inspect.iscoroutine(o) is updated to test if 'o' is a native coroutine object. Before this commit it used abc.Coroutine, and it was requested to update inspect.isgenerator(o) to use abc.Generator; it was decided, however, that inspect functions should really be tailored for checking for native types. 6. sys.set_coroutine_wrapper(w) API is updated to work with only native coroutines. Since types.coroutine decorator supports any type of callables now, it would be confusing that it does not work for all types of coroutines. 7. Exceptions logic in generators C implementation was updated to raise clearer messages for coroutines: Before: TypeError("generator raised StopIteration") After: TypeError("coroutine raised StopIteration")
