delta/cpython-git.git/Python, branch refactor-lambda-parameters github.com: python/cpython.git bpo-40334: Support type comments (GH-19780) 2020-04-30T19:12:19+00:00 Guido van Rossum guido@python.org 2020-04-30T19:12:19+00:00 c001c09e9059ba04bc088349cd87a1374dc0754f This implements full support for # type: <type> comments, # type: ignore <stuff> comments, and the func_type parsing mode for ast.parse() and compile(). Closes https://github.com/we-like-parsers/cpython/issues/95. (For now, you need to use the master branch of mypy, since another issue unique to 3.9 had to be fixed there, and there's no mypy release yet.) The only thing missing is `feature_version=N`, which is being tracked in https://github.com/we-like-parsers/cpython/issues/124.

bpo-40421: Add PyFrame_GetBack() function (GH-19765) 2020-04-29T01:28:46+00:00 Victor Stinner vstinner@python.org 2020-04-29T01:28:46+00:00 703647732359200c54f1d2e695cc3a06b9a96c9a New PyFrame_GetBack() function: get the frame next outer frame.

PyFrame_GetCode(frame): return a borrowed reference to the frame
code.

Replace frame->f_code with PyFrame_GetCode(frame) in most code,
except in frameobject.c, genobject.c and ceval.c.

Also add PyFrame_GetLineNumber() to the limited C API.

This commit also allows to pass flags to the new parser in all interfaces and fixes a bug in the parser generator that was causing to inline rules with actions, making them disappear.

If _PyCode_InitOpcache() fails in _PyEval_EvalFrameDefault(), use
"goto exit_eval_frame;" rather than "return NULL;" to exit the
function in a consistent state. For example, tstate->frame is now
reset properly.

This is invoked by mypy, using ast.parse(source, "<func_type>", "func_type"). Since the new grammar doesn't yet support the func_type_input start symbol we must use the old compiler in this case to prevent a crash.
