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: Rename pycore_ast.h functions to _PyAST_xxx() (GH-25252)

2021-04-07T19:34:22+00:00

Rename AST functions of pycore_ast.h to use the "_PyAST_" prefix.
Remove macros creating aliases without prefix. For example, Module()
becomes _PyAST_Module(). Update Grammar/python.gram to use
_PyAST_xxx() functions.

bpo-43244: Remove Yield macro from pycore_ast.h (GH-25243)

2021-04-07T11:01:09+00:00

* pycore_ast.h no longer defines the Yield macro.
* Fix a compiler warning on Windows: "warning C4005: 'Yield': macro
  redefinition".
* Python-ast.c now defines directly functions with their real
  _Py_xxx() name, rather than xxx().
* Remove "#undef Yield" in C files including pycore_ast.h.

bpo-43244: Remove the pyarena.h header (GH-25007)

2021-03-24T01:23:01+00:00

Remove the pyarena.h header file with functions:

* PyArena_New()
* PyArena_Free()
* PyArena_Malloc()
* PyArena_AddPyObject()

These functions were undocumented, excluded from the limited C API,
and were only used internally by the compiler.

Add pycore_pyarena.h header. Rename functions:

* PyArena_New() => _PyArena_New()
* PyArena_Free() => _PyArena_Free()
* PyArena_Malloc() => _PyArena_Malloc()
* PyArena_AddPyObject() => _PyArena_AddPyObject()

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.
