* bpo-43897: Reject "_" captures and top-level MatchStar in the AST validator ↵Brandt Bucher2021-07-291-20/+28

* bpo-43244: Remove ast.h, asdl.h, Python-ast.h headers (GH-24933)Victor Stinner2021-03-231-2/+1
| | | | | | | | | | | | | | | | These functions were undocumented and excluded from the limited C API. Most names defined by these header files were not prefixed by "Py" and so could create names conflicts. For example, Python-ast.h defined a "Yield" macro which was conflict with the "Yield" name used by the Windows <winbase.h> header. Use the Python ast module instead. * Move Include/asdl.h to Include/internal/pycore_asdl.h. * Move Include/Python-ast.h to Include/internal/pycore_ast.h. * Remove ast.h header file. * pycore_symtable.h no longer includes Python-ast.h.
* bpo-43244: Remove the PyAST_Validate() function (GH-24911)Victor Stinner2021-03-181-1/+1
| | | | | | | | | | | | Remove the PyAST_Validate() function. It is no longer possible to build a AST object (mod_ty type) with the public C API. The function was already excluded from the limited C API (PEP 384). Rename PyAST_Validate() function to _PyAST_Validate(), move it to the internal C API, and don't export it anymore (replace PyAPI_FUNC with extern). The function was added in bpo-12575 by the commit 832bfe2ebd5ecfa92031cd40c8b41835ba90487f.

| | | | | | | | - Use the proper asdl sequence when creating empty arguments - Remove reduntant casts (thanks to new typed asdl_sequences) - Remove MarshalPrototypeVisitor and some utilities from asdl generator - Fix the header of `Python/ast.c` (kept from pgen times) Automerge-Triggered-By: @pablogsal
* bpo-41746: Add type information to asdl_seq objects (GH-22223)Pablo Galindo2020-09-161-12/+13
| | | | | | | | | | | | | * 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.

* Cut disused recode_encoding logic in _PyBytes_DecodeEscape. (GH-16013)Greg Price2019-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | All call sites pass NULL for `recode_encoding`, so this path is completely untested. That's been true since before Python 3.0. It adds significant complexity to this logic, so it's best to take it out. All call sites now have a literal NULL, and that's been true since commit 768921cf3 eliminated a conditional (`foo ? bar : NULL`) at the call site in Python/ast.c where we're parsing a bytes literal. But even before then, that condition `foo` had been a constant since unadorned string literals started meaning Unicode, in commit 572dbf8f1 aka v3.0a1~1035 . The `unicode` parameter is already unused, so mark it as unused too. The code that acted on it was also taken out before Python 3.0, in commit 8d30cc014 aka v3.0a1~1031 . The function (PyBytes_DecodeEscape) is exposed in the API, but it's never been documented.

| | | | | | | | | | | | | | | | | | DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals just as it did in 3.7. SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner.

| | | | | Nested BinOp instances (e.g. a+b+c) had a wrong col_offset for the second BinOp (e.g. 2 instead of 0 in the example). Fix it by using the correct st node to copy the line and col_offset from in ast.c.
