Produce cleaner bytecode for 'with' and 'async with' by generating separate code for normal and exceptional paths. (#6641)

2019-11-21T09:11:43+00:00

Remove BEGIN_FINALLY, END_FINALLY, CALL_FINALLY and POP_FINALLY bytecodes. Implement finally blocks by code duplication.
Reimplement frame.lineno setter using line numbers rather than bytecode offsets.

bpo-36710: Add PyInterpreterState.runtime field (GH-17270)

2019-11-20T01:27:56+00:00

Add PyInterpreterState.runtime field: reference to the _PyRuntime
global variable. This field exists to not have to pass runtime in
addition to tstate to a function.  Get runtime from tstate:
tstate->interp->runtime.

Remove "_PyRuntimeState *runtime" parameter from functions already
taking a "PyThreadState *tstate" parameter.

_PyGC_Init() first parameter becomes "PyThreadState *tstate".

bpo-38644: Add _PyEval_EvalCode() (GH-17183)

2019-11-16T00:03:22+00:00

_PyFunction_Vectorcall() now pass tstate to function calls.

bpo-38644: Add _PyObject_Call() (GH-17089)

2019-11-14T12:36:21+00:00

* Add pycore_call.h internal header file.
* Add _PyObject_Call(): PyObject_Call() with tstate
* Add _PyObject_CallNoArgTstate(): _PyObject_CallNoArg() with tstate
* Add _PyObject_FastCallDictTstate(): _PyObject_FastCallDict()
  with tstate
* _PyObject_Call_Prepend() now takes tstate
* Replace _PyObject_FastCall() calls
  with _PyObject_VectorcallTstate() calls

bpo-38644: Add _PyEval_EvalFrame() with tstate (GH-17131)

2019-11-14T11:20:46+00:00

Add _PyEval_EvalFrame() static inline function to get eval_frame from
tstate->interp.

bpo-37645: add new function _PyObject_FunctionStr() (GH-14890)

2019-11-05T15:48:04+00:00

Additional note: the `method_check_args` function in `Objects/descrobject.c` is written in such a way that it applies to all kinds of descriptors. In particular, a future re-implementation of `wrapper_descriptor` could use that code.

bpo-38644: Pass tstate to _Py_CheckFunctionResult() (GH-17050)

2019-11-05T00:22:12+00:00

* Add tstate parameter to _Py_CheckFunctionResult()
* Add _PyErr_FormatFromCauseTstate()
* Replace PyErr_XXX(...) with _PyErr_XXX(state, ...)

bpo-38644: Pass tstate to Py_EnterRecursiveCall() (GH-16997)

2019-11-04T23:51:22+00:00

* Add _Py_EnterRecursiveCall() and _Py_LeaveRecursiveCall() which
  require a tstate argument.
* Pass tstate to _Py_MakeRecCheck() and  _Py_CheckRecursiveCall().
* Convert Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() macros
  to static inline functions.

_PyThreadState_GET() is the most efficient way to get the tstate, and
so using it with _Py_EnterRecursiveCall() and
_Py_LeaveRecursiveCall() should be a little bit more efficient than
using Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() which use
the "slower" PyThreadState_GET().

bpo-38644: Add Py_EnterRecursiveCall() to the limited API (GH-17046)

2019-11-04T18:48:34+00:00

Provide Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() as
regular functions for the limited API. Previously, there were defined
as macros, but these macros didn't work with the limited API which
cannot access PyThreadState.recursion_depth field.

Remove _Py_CheckRecursionLimit from the stable ABI.

Add Include/cpython/ceval.h header file.

bpo-38310: Predict BUILD_MAP_UNPACK_WITH_CALL -> CALL_FUNCTION_EX. (GH-16467)
