bpo-36332: Allow compile() to handle AST objects with assignment expressions (GH-12398)

2019-03-18T13:51:53+00:00

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.

bpo-36052: Raise a SyntaxError when assigning a value to debug with := (GH-11958)

2019-02-21T10:11:53+00:00

Trying to assign a value to __debug__ using the assignment operator is supposed to fail, but
a missing check for forbidden names when setting the context in the ast was preventing this behaviour.

bpo-36049: Fix compiler warning in Python/ast.c (GH-11949)

2019-02-19T22:51:53+00:00

bpo-35766 follow-up: Add an error check to new_type_comment() (#11766)

2019-02-11T16:10:42+00:00

If PyUnicode_DecodeUTF8() returns NULL, PyArena_AddPyObject() would crash.
Found by @msullivan for https://github.com/python/typed_ast/pull/93.

Fix compiler warning about non initialised variable (GH-11806)
