* gh-117139: Garbage collector support for deferred refcounting (#122956)Sam Gross2024-08-153-18/+93
| | | | | | | | | | The free-threaded GC now visits interpreter stacks to keep objects that use deferred reference counting alive. Interpreter frames are zero initialized in the free-threaded GC so that the GC doesn't see garbage data. This is a temporary measure until stack spilling around escaping calls is implemented.

* GH-120024: Remove `CHECK_EVAL_BREAKER` macro. (GH-122968)Mark Shannon2024-08-146-311/+636
| | | | | * Factor some instructions into micro-ops to isolate CHECK_EVAL_BREAKER for escape analysis * Eliminate CHECK_EVAL_BREAKER macro

* gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952)Eric Snow2024-08-131-4/+8
| | | As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working. This is a minimal fix just to get builds working again. There are actually a number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need to be resolved separately.
* GH-122390: Replace `_Py_GetbaseOpcode` with `_Py_GetBaseCodeUnit` (GH-122942)Mark Shannon2024-08-134-46/+52

* gh-117139: Replace _PyList_FromArraySteal with stack ref variant (#122830)Sam Gross2024-08-123-29/+3
| | | | | | | This replaces `_PyList_FromArraySteal` with `_PyList_FromStackRefSteal`. It's functionally equivalent, but takes a `_PyStackRef` array instead of an array of `PyObject` pointers. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-117139: Fix a few `_PyStackRef` related bugs (#122831)Sam Gross2024-08-123-16/+14
| | | | | | `BUILD_SET` should use a borrow instead of a steal. The cleanup in `_DO_CALL` `CONVERSION_FAILED` was incorrect. Co-authored-by: Ken Jin <kenjin@python.org>
* GH-122869: Add missing tier two optimizer cases (GH-122936)Mark Shannon2024-08-122-4/+31

* gh-122697: Fix free-threading memory leaks at shutdown (#122703)Sam Gross2024-08-083-1/+17
| | | | | | | | | | | | | | | We were not properly accounting for interpreter memory leaks at shutdown and had two sources of leaks: * Objects that use deferred reference counting and were reachable via static types outlive the final GC. We now disable deferred reference counting on all objects if we are calling the GC due to interpreter shutdown. * `_PyMem_FreeDelayed` did not properly check for interpreter shutdown so we had some memory blocks that were enqueued to be freed, but never actually freed. * `_PyType_FinalizeIdPool` wasn't called at interpreter shutdown.
* gh-122562: fix dump_symtable for ste_free and ste_child_free removal (#122825)Irit Katriel2024-08-081-1/+1

* gh-118814: Fix the TypeVar constructor when name is passed by keyword ↵Serhiy Storchaka2024-08-071-1/+1
| | | | | | | | (GH-122664) Fix _PyArg_UnpackKeywordsWithVararg for the case when argument for positional-or-keyword parameter is passed by keyword. There was only one such case in the stdlib -- the TypeVar constructor.
* 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.
