Bénédikt Tran 1775091dc1 gh-129173: Use _PyUnicodeError_GetParams in PyCodec_SurrogatePassErrors (GH-129134) 2025-02-14 18:34:32 +01:00
Yan Yanchii 334589f619 gh-126835: Set location for noped out instructions after constant folding in CFG. (#130109) 2025-02-14 14:15:08 +00:00
Sam Gross 451f291baa gh-128130: Fix unhandled keyboard interrupt data race (gh-129975) 
Use an atomic operation when setting
`_PyRuntime.signals.unhandled_keyboard_interrupt`. We now only clear the
variable at the start of `_PyRun_Main`, which is the same function where
we check it.

This avoids race conditions where previously another thread might call
`run_eval_code_obj()` and erroneously clear the unhandled keyboard
interrupt.

Sam Gross 0559339ccd gh-130019: Fix data race in _PyType_AllocNoTrack (gh-130058) 
The reference count fields, such as `ob_tid` and `ob_ref_shared`, may be
accessed concurrently in the free threading build by a `_Py_TryXGetRef`
or similar operation. The PyObject header fields will be initialized by
`_PyObject_Init`, so only call `memset()` to zero-initialize the remainder
of the allocation.

Yan Yanchii 140e69c4a8 gh-126835: Move const folding of lists & sets from ast_opt.c to flowgraph.c (#130032) 2025-02-13 12:11:07 +00:00
Sam Gross e09442089e gh-130030: Fix crash on 32-bit Linux with free threading (gh-130043) 
The `gc_get_refs` assertion needs to be after we check the alive and
unreachable bits. Otherwise, `ob_tid` may store the actual thread id
instead of the computed `gc_refs`, which may trigger the assertion if
the `ob_tid` looks like a negative value.

Also fix a few type warnings on 32-bit systems.

Neil Schemenauer cdcacec79f gh-129201: Use prefetch in GC mark alive phase. (gh-129203) 
For the free-threaded version of the cyclic GC, restructure the "mark alive" phase to use software prefetch instructions.  This gives a speedup in most cases when the number of objects is large enough.  The prefetching is enabled conditionally based on the number of long-lived objects the GC finds.

Kirill Podoprigora 7d0521d5fc gh-126835: Move optimization of constant sequence creation from codegen to CFG (#129426) 
Codegen phase has an optimization that transforms
```
LOAD_CONST x
LOAD_CONST y
LOAD_CONXT z
BUILD_LIST/BUILD_SET (3)
```
->
```
BUILD_LIST/BUILD_SET (0)
LOAD_CONST (x, y, z)
LIST_EXTEND/SET_UPDATE 1
```
This optimization has now been moved to CFG phase to make #128802 work.

Sam Gross 5ff2fbc026 gh-129236: Use stackpointer in free threaded GC (#129240) 
The stack pointers in interpreter frames are nearly always valid now, so
use them when visiting each thread's frame. For now, don't collect
objects with deferred references in the rare case that we see a frame
with a NULL stack pointer.
