bpo-21120: Exclude Python-ast.h, ast.h and asdl.h from the limited API (#14634)

2019-09-12T09:27:14+00:00

The PyArena type is not part of the limited API, so these headers
shouldn't be part of it either.

bpo-37593: Swap the positions of posonlyargs and args in the constructor of ast.parameters nodes (GH-14778)

bpo-37253: Remove PyAST_obj2mod_ex() function (GH-14020)

2019-06-13T07:18:45+00:00

PyAST_obj2mod_ex() is similar to PyAST_obj2mod() with an additional
'feature_version' parameter which is unused.

bpo-37050: Remove expr_text from FormattedValue ast node, use Constant node instead (GH-13597)

2019-05-27T19:31:52+00:00

When using the "=" debug functionality of f-strings, use another Constant node (or a merged constant node) instead of adding expr_text to the FormattedValue node.

bpo-36878: Track extra text added to 'type: ignore' in the AST (GH-13479)

2019-05-22T14:54:20+00:00

GH-13238 made extra text after a # type: ignore accepted by the parser.
This finishes the job and actually plumbs the extra text through the
parser and makes it available in the AST.

bpo-36817: Add f-string debugging using '='. (GH-13123)

2019-05-08T20:28:48+00:00

If a "=" is specified a the end of an f-string expression, the f-string will evaluate to the text of the expression, followed by '=', followed by the repr of the value of the expression.

bpo-36540: PEP 570 -- Implementation (GH-12701)

2019-04-29T12:36:57+00:00

This commit contains the implementation of PEP570: Python positional-only parameters.

* Update Grammar/Grammar with new typedarglist and varargslist

* Regenerate grammar files

* Update and regenerate AST related files

* Update code object

* Update marshal.c

* Update compiler and symtable

* Regenerate importlib files

* Update callable objects

* Implement positional-only args logic in ceval.c

* Regenerate frozen data

* Update standard library to account for positional-only args

* Add test file for positional-only args

* Update other test files to account for positional-only args

* Add News entry

* Update inspect module and related tests

bpo-36280: Add Constant.kind field (GH-12295)

2019-03-13T20:00:46+00:00

The value is a string for string and byte literals, None otherwise.
It is 'u' for u"..." literals, 'b' for b"..." literals, '' for "..." literals.
The 'r' (raw) prefix is ignored.
Does not apply to f-strings.

This appears sufficient to make mypy capable of using the stdlib ast module instead of typed_ast (assuming a mypy patch I'm working on).

WIP: I need to make the tests pass. @ilevkivskyi @serhiy-storchaka

bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)

2019-03-07T20:38:08+00:00

This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.)

bpo-36187: Remove NamedStore. (GH-12167)

2019-03-05T18:42:06+00:00

NamedStore has been replaced with Store. The difference between
NamedStore and Store is handled when precess the NamedExpr node
one level upper.
