Updates rusty_alloc from 2.2.0 to 2.2.2

Release notes

Sourced from rusty_alloc's releases.

rusty_alloc-api-v2.2.2

Performance

• GlobalAlloc methods are #[inline], as the mimalloc crate's are, so rustc's __rust_alloc / __rust_dealloc shims carry the fast path instead of jumping to it, and dealloc is the free fast path with its null test folded away. Measured whole-program against 2.2.0 on two deterministic Rust workloads (bench/rust-globalalloc.sh): -21.1 % and -5.8 %.
• Layouts aligned up to two words (16 bytes on 64-bit) come from the natural size classes, which are already aligned that far, instead of the aligned path; every hashbrown table is such a layout. tests/natural_align.rs pins the alignment for every size class through alloc, alloc_zeroed and realloc.
• realloc keeps a block in place at any alignment when it fits instead of always allocating, copying and freeing above 8 bytes of alignment: -27.3 % on an over-aligned buffer workload.

rusty_alloc-v2.2.2

Fixed

• (prim) macOS range_is_reserved via mach_vm_region, not mincore
• (blockmap) clear a reused slot's map pointer -- stress_mt aborted on 4 CPUs
• (prim) build on macOS -- mincore's out-vector type differs on Apple

Other

• (unsafe) record the two macOS range_is_reserved sites; ratchet 963 -> 965

rusty_alloc-api-v2.2.1

Performance

• GlobalAlloc methods are #[inline], as the mimalloc crate's are, so rustc's __rust_alloc / __rust_dealloc shims carry the fast path instead of jumping to it, and dealloc is the free fast path with its null test folded away.

rusty_alloc-v2.2.1

Fixed

• Growing a huge block with realloc copied its whole reservation. A huge segment's page reported its usable size as the chunk-rounded reservation minus the header — 64 MiB for a 33 MB request, 96 MiB for a 64 MB one — and realloc copies usable_size bytes when it moves a block,

Updates pyo3 from 0.29.2 to 0.29.3

Release notes

Sourced from pyo3's releases.

PyO3 0.29.3

This release is a series of fixes worth landing to the PyO3 0.29 series; the PyO3 0.30 release is planned to follow within a few weeks, however during the development cycle a number of rough edges were discovered which were deemed worth a backport.

The patch broadly includes:

• a further fix the to the opt-out of raw-dylib linking for Windows introduced in PyO3 0.29.1 (the switch to raw-dylib linking was introduced in PyO3 0.29.0),
• fixes to support GraalPy on windows,
• a handful of small performance optimizations,
• a number of non-breaking fixes to the experimental-inspect type stub generation (expect more improvements in 0.30), and
• various other bugfixes such as to FFI definitions, to resolve crashes, and to fix clippy lints caused by PyO3 macros.

For a full list of the exact fixes please consult the CHANGELOG.

Thank you to the following contributors for the improvements:

[0.29.3] - 2026-09-30

Packaging

• Support GraalPy on Windows. #6406

Added

• Add FFI definitions PyModule_GetState_DuringGC, PyModule_GetToken_DuringGC, PyObject_GetTypeData_DuringGC, PyType_GetModuleState_DuringGC, PyType_GetBaseByToken_DuringGC, PyType_GetModule_DuringGC, and PyType_GetModuleByToken_DuringGC for Python 3.15 and up. #6419

Changed

• Optimize u128/i128 conversions on Python 3.15+. #6160
• Preallocate output sets when extracting Python set and frozenset values into Rust hash sets. #6225
• Optimize PyBytes::as_bytes() when not using abi3 or abi3t. #6377

Removed

• Remove FFI definitions PyExc_RecursionErrorInst and Py_UseClassExceptionsFlag (not present in supported Python versions). #6421

Fixed

• Revert removal of FFI definition _PyFrameEvalFunction, _PyInterpreterState_GetEvalFrameFunc and _PyInterpreterState_SetEvalFrameFunc, which are not currently treated as CPython private API despite their name. #6195
• Fix FFI definition PyUnstable_Eval_RequestCodeExtraIndex FFI binding to link to the private CPython symbol on Python versions before 3.12. #6195
• Fix FFI definitions PyByteArray_GET_SIZE, PyList_GET_SIZE, and PySet_GET_SIZE to use an atomic load for free-threaded Python. #6230
• experimental-inspect: deduplicate repeated members of a type union in the generated stubs, and put a space on both sides of the | rather than only before it. #6273
• experimental-inspect: __next__ and __anext__ returning Option<T> (or PyResult<Option<T>>) are now introspected as returning T, since None stops the iteration instead of being yielded. #6274
• Fix clippy::clone_on_copy warnings triggered on nightly Rust by #[pyclass(from_py_object)] on classes which implement Copy. #6309
• experimental-inspect: __pow__, __rpow__ and __get__ now introspect their trailing argument as defaulting to None, matching the CPython slot wrappers which substitute None when it is omitted. #6363
• experimental-inspect: fix the stubs of a package nested inside another package being written into a directory named after its parent instead of its own name. #6365
• Fix many unresolved symbols when linking for PyPy due to incorrect link names in pyo3-ffi. #6389
• Fix empty tuple type hints being rendered as invalid tuple[] instead of tuple[()] in generated stubs and PyStaticExpr display. #6393
• experimental-inspect: escape stub docstrings to prevent invalid Python syntax. #6394
• experimental-inspect: fix the generated type annotation for PyBuffer on python <3.12 by using typing_extensions.Buffer instead of collections.abc.Buffer. #6395
• Fix string constants containing control characters rendering as invalid Python in Display for PyStaticExpr. #6397
• Fix crash when a detached thread is terminated while trying to reattach during interpreter finalization. #6404
• Fix link failures on 32-bit Windows when raw-dylib linking is disabled. #6410
• Fix DLL load failures on Windows with PyPy when raw-dylib linking is disabled. #6410
• Fix FFI definition PyVectorcall_Call failing to link on Python 3.11 and older. #6410
• Fix many unresolved data symbols when linking for PyPy due to incorrect link names in pyo3-ffi. #6421
• Fix linker errors on PyPy for outdated FFI definitions where PyPy moved from a function to a macro. #6422
• Fix crash when GC traverses a #[pyclass] type object during class attribute initialization. #6453
