* gh-118926: Spill deferred references to stack in cases generator (#122748)Sam Gross2024-08-073-35/+41
| | | | | | | This automatically spills the results from `_PyStackRef_FromPyObjectNew` to the in-memory stack so that the deferred references are visible to the GC before we make any possibly escaping call. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-122759: Remove `assert` from `RERAISE` error handling (#122760)sobolevn2024-08-072-2/+0
|
* gh-117139: Fix an incorrect borrow in bytecodes.c (#122318)Sam Gross2024-08-073-11/+14
| | | `_PyDict_SetItem_Take2` steals both the key (i.e., `sub`) and the value.
* gh-122728: Fix SystemError in PyEval_GetLocals() (#122735)Victor Stinner2024-08-061-1/+1
| | | | | | | Fix PyEval_GetLocals() to avoid SystemError ("bad argument to internal function"). Don't redefine the 'ret' variable in the if block. Add an unit test on PyEval_GetLocals().
* gh-122417: Implement per-thread heap type refcounts (#122418)Sam Gross2024-08-063-51/+231
| | | | | | | The free-threaded build partially stores heap type reference counts in distributed manner in per-thread arrays. This avoids reference count contention when creating or destroying instances. Co-authored-by: Ken Jin <kenjin@python.org>

* gh-122313: Clean up deep recursion guarding code in the compiler (GH-122640)Serhiy Storchaka2024-08-033-162/+164
| | | | | | | | | Add ENTER_RECURSIVE and LEAVE_RECURSIVE macros in ast.c, ast_opt.c and symtable.c. Remove VISIT_QUIT macro in symtable.c. The current recursion depth counter only needs to be updated during normal execution -- all functions should just return an error code if an error occurs.
* GH-117224: Move the body of a few large-ish micro-ops into helper functions ↵Mark Shannon2024-08-024-335/+159

* Replace PyObject_Del with PyObject_Free (#122453)Victor Stinner2024-08-011-1/+1
| | | | PyObject_Del() is just a alias to PyObject_Free() kept for backward compatibility. Use directly PyObject_Free() instead.

* gh-117657: Avoid race in `PAUSE_ADAPTIVE_COUNTER` in free-threaded build ↵Sam Gross2024-07-301-1/+2
| | | | | | | (#122190) The adaptive counter doesn't do anything currently in the free-threaded build and TSan reports a data race due to concurrent modifications to the counter.

* gh-122234: fix accuracy issues for sum() (#122236)Sergey B Kirpichev2024-07-291-11/+13
| | | | | | | | * Use compensated summation for complex sums with floating-point items. This amends #121176. * sum() specializations for floats and complexes now use PyLong_AsDouble() instead of PyLong_AsLongAndOverflow() and compensated summation as well.

* gh-122201: Lock mutex when setting handling_thread to NULL (#122204)Sam Gross2024-07-261-3/+15
| | | | | In the free-threaded build, we need to lock pending->mutex when clearing the handling_thread in order not to race with a concurrent make_pending_calls in the same interpreter.

* gh-100240: Use a consistent implementation for freelists (#121934)Sam Gross2024-07-226-104/+13
| | | | | | | | This combines and updates our freelist handling to use a consistent implementation. Objects in the freelist are linked together using the first word of memory block. If configured with freelists disabled, these operations are essentially no-ops.
* gh-120973: Fix thread-safety issues with `threading.local` (#121655)mpage2024-07-191-0/+3
| | | | | | This is a small refactoring to the current design that allows us to avoid manually iterating over threads. This should also fix gh-118490.
