* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-032-5/+5
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* GH-98831: Support cache effects in super- and macro instructions (#99601)Guido van Rossum2022-12-031-2/+2

* gh-99741: Clean Up the _xxsubinterpreters Module (gh-99940)Eric Snow2022-12-021-9/+11
| | | | | This cleanup up resolves a few subtle bugs and makes the implementation for multi-phase init much cleaner. https://github.com/python/cpython/issues/99741

* GH-98831: Add `macro` and `op` and their implementation to DSL (#99495)Guido van Rossum2022-11-232-62/+73
| | | | | | | | | | | | | | Newly supported interpreter definition syntax: - `op(NAME, (input_stack_effects -- output_stack_effects)) { ... }` - `macro(NAME) = OP1 + OP2;` Also some other random improvements: - Convert `WITH_EXCEPT_START` to use stack effects - Fix lexer to balk at unrecognized characters, e.g. `@` - Fix moved output names; support object pointers in cache - Introduce `error()` method to print errors - Introduce read_uint16(p) as equivalent to `*p` Co-authored-by: Brandt Bucher <brandtbucher@gmail.com>
* gh-88226: Emit TARGET labels in Python/ceval.c when debugging, even if ↵Skip Montanaro2022-11-221-4/+21
| | | | | | | computed gotos aren't enabled (GH-98265) Keep target labels when debugging, but don't warn about lack of use. Co-authored-by: Eryk Sun <eryksun@gmail.com>
* gh-99537: Use Py_SETREF() function in C code (#99657)Victor Stinner2022-11-228-25/+11
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.

* gh-99578: Fix refleak in _imp.create_builtin() (#99642)Victor Stinner2022-11-211-1/+2
| | | | Fix a reference bug in _imp.create_builtin() after the creation of the first sub-interpreter for modules "builtins" and "sys".
* gh-99337: Fix compile errors with gcc 12 on macOS (#99470)Ronald Oussoren2022-11-211-3/+4
| | | | | | | | Fix a number of compile errors with GCC-12 on macOS: 1. In pylifecycle.c the compile rejects _Pragma within a declaration 2. posixmodule.c was missing a number of ..._RUNTIME macros for non-clang on macOS 3. _ctypes assumed that __builtin_available is always present on macOS

|
* gh-81057: Move contextvars-related Globals to _PyRuntimeState (gh-99400)Eric Snow2022-11-162-78/+46
| | | | | This is part of the effort to consolidate global variables, to make them easier to manage (and make it easier to later move some of them to PyInterpreterState). https://github.com/python/cpython/issues/81057
* gh-81057: Move More Globals in Core Code to _PyRuntimeState (gh-99516)Eric Snow2022-11-168-23/+20

* gh-99300: Use Py_NewRef() in Python/Python-ast.c (#99499)Victor Stinner2022-11-151-140/+73
| | | | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in Python/Python-ast.c. Update Parser/asdl_c.py to regenerate code.

* gh-81057: Move Global Variables Holding Objects to _PyRuntimeState. (gh-99487)Eric Snow2022-11-142-1/+5

* gh-81057: Move PyImport_Inittab to _PyRuntimeState (gh-99402)Eric Snow2022-11-123-6/+68
| | | | | We actually don't move PyImport_Inittab. Instead, we make a copy that we keep on _PyRuntimeState and use only that after Py_Initialize(). We also prevent folks from modifying PyImport_Inittab (the best we can) after that point. https://github.com/python/cpython/issues/81057
* gh-81057: Move the Allocators to _PyRuntimeState (gh-99217)Eric Snow2022-11-112-3/+6
| | | | | The global allocators were stored in 3 static global variables: _PyMem_Raw, _PyMem, and _PyObject. State for the "small block" allocator was stored in another 13. That makes a total of 16 global variables. We are moving all 16 to the _PyRuntimeState struct as part of the work for gh-81057. (If PEP 684 is accepted then we will follow up by moving them all to PyInterpreterState.) https://github.com/python/cpython/issues/81057
* gh-81057: Add PyInterpreterState.static_objects (gh-99397)Eric Snow2022-11-111-1/+1
| | | | | As we consolidate global variables, we find some objects that are almost suitable to add to _PyRuntimeState.global_objects, but have some small/sneaky bit of per-interpreter state (e.g. a weakref list). We're adding PyInterpreterState.static_objects so we can move such objects there. (We'll removed the _not_used field once we've added others.) https://github.com/python/cpython/issues/81057
* gh-81057: Move the Extension Modules Cache to _PyRuntimeState (gh-99355)Eric Snow2022-11-111-28/+50
| | | | | We also move the closely related max_module_number and add comments documenting the group of struct members. https://github.com/python/cpython/issues/81057
* gh-99254: remove all unused consts from code objects (GH-99255)Irit Katriel2022-11-111-19/+92

* GH-98831: Remove all remaining DISPATCH() calls from bytecodes.c (#99271)Guido van Rossum2022-11-102-169/+175
