* gh-102856: Python tokenizer implementation for PEP 701 (#104323)Marta Gómez Macías2023-05-215-8/+65
| | | | | | | | | | | This commit replaces the Python implementation of the tokenize module with an implementation that reuses the real C tokenizer via a private extension module. The tokenize module now implements a compatibility layer that transforms tokens from the C tokenizer into Python tokenize tokens for backward compatibility. As the C tokenizer does not emit some tokens that the Python tokenizer provides (such as comments and non-semantic newlines), a new special mode has been added to the C tokenizer mode that currently is only used via the extension module that exposes it to the Python layer. This new mode forces the C tokenizer to emit these new extra tokens and add the appropriate metadata that is needed to match the old Python implementation.

* gh-103763: Implement PEP 695 (#103764)Jelle Zijlstra2023-05-163-1964/+2573
| | | | | | | | | | | | | | This implements PEP 695, Type Parameter Syntax. It adds support for: - Generic functions (def func[T](): ...) - Generic classes (class X[T](): ...) - Type aliases (type X = ...) - New scoping when the new syntax is used within a class body - Compiler and interpreter changes to support the new syntax and scoping rules Co-authored-by: Marc Mueller <30130371+cdce8p@users.noreply.github.com> Co-authored-by: Eric Traut <eric@traut.com> Co-authored-by: Larry Hastings <larry@hastings.org> Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).

* gh-103718: Correctly set f-string buffers in all cases (GH-103815)Lysandros Nikolaou2023-04-251-8/+6
| | | | | | Turns out we always need to remember/restore fstring buffers in all of the stack of tokenizer modes, cause they might change to `TOK_REGULAR_MODE` and have newlines inside the braces (which is when we need to reallocate the buffer and restore the fstring ones).

* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-3/+5
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.
