| | | | | Argument clinic now generates fast inline code for positional parsing, so the manually implemented type check in math.dist can be removed.
* bpo-35582: Argument Clinic: Optimize the "all boring objects" case. (GH-11520)Serhiy Storchaka2019-01-111-7/+7
| | | | | Use _PyArg_CheckPositional() and inlined code instead of PyArg_UnpackTuple() and _PyArg_UnpackStack() if all parameters are positional and use the "object" converter.

| | | | arguments. (#4746)
* bpo-29464: Rename METH_FASTCALL to METH_FASTCALL|METH_KEYWORDS and make (#1955)Serhiy Storchaka2017-07-031-27/+7
| | | | | the bare METH_FASTCALL be used for functions with positional-only parameters.
* bpo-30600: Fix error messages (condition order in Argument Clinic) (#2051)Sylvain2017-06-101-17/+17
| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".
