bpo-38605: Revert making 'from future import annotations' the default (GH-25490)

2021-04-21T11:41:19+00:00

This reverts commits 044a1048ca93d466965afc027b91a5a9eb9ce23c and 1be456ae9d53bb1cba2b24fc86175c282d1c2169, adapting the code to changes that happened after it.

bpo-43244: Add pycore_compile.h header file (GH-25000)

2021-03-23T23:51:50+00:00

Remove the compiler functions using "struct _mod" type, because the
public AST C API was removed:

* PyAST_Compile()
* PyAST_CompileEx()
* PyAST_CompileObject()
* PyFuture_FromAST()
* PyFuture_FromASTObject()

These functions were undocumented and excluded from the limited C API.

Rename functions:

* PyAST_CompileObject() => _PyAST_Compile()
* PyFuture_FromASTObject() => _PyFuture_FromAST()

Moreover, _PyFuture_FromAST() is no longer exported (replace
PyAPI_FUNC() with extern). _PyAST_Compile() remains exported for
test_peg_generator.

Remove also compatibility functions:

* PyAST_Compile()
* PyAST_CompileEx()
* PyFuture_FromAST()

bpo-43244: Add pycore_ast.h header file (GH-24908)

2021-03-17T22:50:50+00:00

Move _PyAST_GetDocString() and _PyAST_ExprAsUnicode() functions the
internal C API: from Include/ast.h to a new
Include/internal/pycore_ast.h header file. Don't export these
functions anymore: replace PyAPI_FUNC() with extern.

Remove also unused includes.

bpo-38605: Make 'from future import annotations' the default (GH-20434)

2020-10-06T20:03:02+00:00

The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions.

For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).

bpo-41746: Add type information to asdl_seq objects (GH-22223)

2020-09-16T18:42:00+00:00

* Add new capability to the PEG parser to type variable assignments. For instance:
```
       | a[asdl_stmt_seq*]=';'.small_stmt+ [';'] NEWLINE { a }
```

* Add new sequence types from the asdl definition (automatically generated)
* Make `asdl_seq` type a generic aliasing pointer type.
* Create a new `asdl_generic_seq` for the generic case using `void*`.
* The old `asdl_seq_GET`/`ast_seq_SET` macros now are typed.
* New `asdl_seq_GET_UNTYPED`/`ast_seq_SET_UNTYPED` macros for dealing with generic sequences.
* Changes all possible `asdl_seq` types to use specific versions everywhere.

bpo-40939: Remove the old parser (Part 2) (GH-21005)

2020-06-20T18:07:25+00:00

Remove some remaining files and Makefile targets for the old parser

bpo-34683: Make SyntaxError column offsets consistently 1-indexed (gh-9338)

2018-09-24T21:12:49+00:00

Also point to start of tokens in parsing errors.

Fixes bpo-34683

bpo-33691: Add _PyAST_GetDocString(). (GH-7236)

2018-05-30T07:56:16+00:00

bpo-32911: Revert bpo-29463. (GH-7121) (GH-7197)

2018-05-29T09:04:55+00:00

Remove the docstring attribute of AST types and restore docstring
expression as a first stmt in their body.
