* 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-119180: Add evaluate functions for type params and type aliases (#122212)Jelle Zijlstra2024-07-272-25/+19

* Manually override bytecode definition in optimizer, to avoid build error ↵Mark Shannon2024-07-262-4/+17
| | | | (GH-122316)
* 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-122294: Burn in the addresses of side exits (GH-122295)Brandt Bucher2024-07-265-17/+22

* gh-122029: Log call events in sys.setprofile when it's a method with c ↵Tian Gao2024-07-231-0/+13
| | | | | function (GH-122072) Log call events in sys.setprofile when it is a method with a C function.
* gh-119180: Add `annotationlib` module to support PEP 649 (#119891)Jelle Zijlstra2024-07-231-0/+1

* gh-121404: move calculation of module start location from compiler_body up ↵Irit Katriel2024-07-221-20/+28
| | | | to compiler_codegen (#122127)
* 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.
* gh-121905: Consistently use "floating-point" instead of "floating point" ↵Serhiy Storchaka2024-07-191-2/+2
| | | | (GH-121907)

* GH-121784: Generate an error during code gen if a variable is marked ↵Mark Shannon2024-07-183-146/+137
| | | | | | | | | | | | `unused`, but is used and thus cached in a prior uop. (#121788) * Reject uop definitions that declare values as 'unused' that are already cached by prior uops * Track which variables are defined and only load from memory when needed * Support explicit `flush` in macro definitions. * Make sure stack is flushed in where needed.
* GH-120024: Use pointer for stack pointer (GH-121923)Mark Shannon2024-07-182-10/+14

* gh-121621: Move asyncio_running_loop to private struct (#121939)Sam Gross2024-07-171-2/+2
| | | | This avoids changing the ABI and keeps the field in the private struct.

* gh-121794: Don't set `ob_tid` to zero in fast-path dealloc (#121799)Sam Gross2024-07-151-11/+54
| | | | | | | | | | | | We should maintain the invariant that a zero `ob_tid` implies the refcount fields are merged. * Move the assignment in `_Py_MergeZeroLocalRefcount` to immediately before the refcount merge. * Update `_PyTrash_thread_destroy_chain` to set `ob_ref_shared` to `_Py_REF_MERGED` when setting `ob_tid` to zero. Also check this invariant with assertions in the GC in debug builds. That uncovered a bug when running out of memory during GC.

| | | | | | * The result has type Py_ssize_t, not intptr_t. * Type cast between unsigned and signdet integer types should be explicit. * Downcasting should be explicit. * Fix integer overflow check in sum().
