* gh-119182: Use public PyUnicodeWriter API in union_repr() (#120797)Victor Stinner2024-06-201-24/+30
| | | | | | | | | | | | | | | The public PyUnicodeWriter API enables overallocation by default and so is more efficient. Benchmark: python -m pyperf timeit \ -s 't = int | float | complex | str | bytes | bytearray' \ ' | memoryview | list | dict' \ 'str(t)' Result: 1.29 us +- 0.02 us -> 1.00 us +- 0.02 us: 1.29x faster

* gh-103763: Implement PEP 695 (#103764)Jelle Zijlstra2023-05-161-2/+6
| | | | | | | | | | | | | | 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-91603: Speed up operator "|" for UnionType (GH-91955)Serhiy Storchaka2022-04-281-87/+70
| | | | | | | | | Reduce the complexity from O((M+N)^2) to O(M*N), where M and N are the length of __args__ for both operands (1 for operand which is not a UnionType). As a consequence, the complexity of parameter substitution in UnionType has been reduced from O(N^3) to O(N^2). Co-authored-by: Yurii Karabas <1998uriyyo@gmail.com>

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
