- Add already_warned() with filter version tracking
- Add type validation for _defaultaction and _onceregistry
- Use direct function names for _warnings pyattr/pyfunction
- Route stdlib::warnings::warn through warn::warn
- Remove spurious EncodingWarning from TextIOWrapper
- Clean up comments and simplify check_matched error handling
- Remove expectedFailure from 3 passing test_warnings tests
* Update `_compat_pickle.py` from 3.14.2
* Update `pickle.py` from 3.14.2
* Update pickletools and tests
* Update all other pickle related files
* Make `test_extcall` to use modified doctest checker
* remove duplicated _call_typing_func_object() functions
Move _call_typing_func_object() code to
stdlib::typing::call_typing_func_object().
Use that function everywhere.
* support | operation between typing.Union and strings
Adds support for performing '|' operation between Union objects and
strings, e.g. forward type references.
For example following code:
from typing import Union
U1 = Union[int, str]
U1 | "float"
The result of the operation above becomes:
int | str | ForwardRef('float')
- Add FieldType enum and FIELD_TYPES static table mapping all
AST node classes to their ASDL field types
- Resolve markers to real Python type objects (GenericAlias,
Union, plain types) at module init in populate_field_types()
- Set class-level None defaults for optional fields
- Replace hardcoded LIST_FIELDS and class-name checks in
slot_init with _field_types-based lookup
- Add expr_context default to Load(), fix ImportFrom.level
default (now None instead of 0)
- Fix __class_getitem__ None check, compile() formatting
- Remove 14 @expectedFailure decorators from test_ast
