* bpo-37540: vectorcall: keyword names must be strings (GH-14682)Jeroen Demeyer2019-08-161-2/+4
| | | | | | | | The fact that keyword names are strings is now part of the vectorcall and `METH_FASTCALL` protocols. The biggest concrete change is that `_PyStack_UnpackDict` now checks that and raises `TypeError` if not. CC @markshannon @vstinner https://bugs.python.org/issue37540

* [Doc] Update opcode for var-positional arguments (#4446)Moses Koledoye2017-11-181-1/+1
| | | `BUILD_MAP_UNPACK_WITH_CALL` was duplicated as the opcode for both var-positional and var-keyword arguments. The opcode for the former was updated as `BUILD_TUPLE_UNPACK_WITH_CALL`.

* bpo-31183: `dis` now handles coroutines & async generators (GH-3077)syncosmic2017-08-181-9/+21
| | | | | | | | | | | | | | Coroutines and async generators use a distinct attribute name for their code objects, so this updates the `dis` module to correctly disassemble objects with those attributes. Due to the increase in the test module length, it also fixes some latent defects in the tests related to how the displayed source line numbers are extracted. https://bugs.python.org/issue31230 is a follow-up issue suggesting we may want to solve this a different way, by instead giving all these object types a common `__code__` attribute, avoiding the need for special casing in the `dis` module.
