Add OrderedDict, marshal, inspect, and chflags bitflagset (#8780)
* Implement _collections.OrderedDict Extracted from #6799: native OrderedDict as a dict subclass, iterator mutation tracking, and mapping-view set operations. * Add OrderedDict, warnings source lines, and socket sendmsg Implement _collections.OrderedDict as a dict subclass with a linked list of insertion-order nodes. Pack struct F/D as native float/double complex pairs, and report unexpected __replace__ field names as a list repr. Register encodings.latin_1 at startup. Reject NUL in input() prompts. Copy non-exact type dicts in mapping order. Fetch warning source lines through _bless_my_loader and unicode splitlines. Keep the last warnings.filters list after deletion. Snapshot sendmsg sequences before converting buffers, parse ancillary ints with __index__, and dispatch AF_CAN by protocol. Store sys.trace and sys.profile on each ThreadSlot so _settraceallthreads/_setprofileallthreads are visible to sys.gettrace/getprofile on other threads. Use <frozen importlib._bootstrap> as frozen importlib co_filename. Keep HEAPTYPE socket objects GC-tracked. Assisted-by: Grok:grok-4.6 * Load marshal via readinto and dump sets in dumps order marshal.load fills a scratch buffer with readinto on a contiguous writable memoryview, and rejects a returned length other than the requested size. set and frozenset dumps write elements in sorted(v, key=marshal.dumps) order. Assisted-by: Grok:grok-4.6 * Add classmethod_descriptor and ABC IS_ABSTRACT flags Give METH_CLASS methods a distinct classmethod_descriptor type. Store Py_TPFLAGS_IS_ABSTRACT from __abstractmethods__ and look up that attribute only in the type's own dict. Expose defaultdict.default_factory as a member descriptor. Inherit bool's unused number slots from int. Mark set and frozenset __contains__ as METH_COEXIST. Parse classmethod, staticmethod, object.__new__, and heap type text signatures. Register interactive source in linecache. Assisted-by: Grok:grok-4.6 * address review: odict reuse, descr call, new wrapper Reuse odict node slots and walk the live list in next_after. Require both | operands to be dicts. Drop the odict iterator on GC clear. Bind classmethod descriptors through descr_get and update IS_ABSTRACT under the type lock. Give odict keys and items sq_contains. Walk tp_new_wrapper past new_wrapper so HEAPTYPE socket subclasses can call socket.__new__. Split FreeBSD Bluetooth protocol constants from Linux values. Assisted-by: Grok:grok-4.6 * Represent chflags bits with bitflagset Assisted-by: Grok:grok-4.6 * Represent access and mode bits with bitflagset Assisted-by: Grok:grok-4.6 * Continue unfinished REPL suites as incomplete input Assisted-by: Grok:grok-4.6 * Add pickle and os.stat inspect signatures Give _pickle.Pickler the clinic constructor text signature and accept fix_imports and buffer_callback as positional-or-keyword. Allow #[pyfunction(text_signature)] and use it so os.stat reports (path, *, dir_fd=None, follow_symlinks=True). Uncomment import _pickle and drop the pickle inspect expectedFailures. Assisted-by: Grok:grok-4.6 * Add Unpickler, dump/load, and lstat signatures Give _pickle Unpickler, dump, dumps, load, and loads clinic text signatures, and os.lstat (path, *, dir_fd=None). Assisted-by: Grok:grok-4.6 * Complete OrderedDict with insertion-order links Move the native OrderedDict into ordered_dict.rs and track order with a linked list of nodes, keeping mapping-view set operations. Assisted-by: Grok:grok-4.6 * address CI: stat casts, HCI_DATA_DIR, passing xfails Compare stat permission bits as Mode so Linux clippy does not flag a u32-to-u32 cast. Export HCI_DATA_DIR with the Bluetooth socket option values. Drop expectedFailure from tests that now pass. Assisted-by: Grok:grok-4.6 * Fix wasm teardown deadlock and bluetooth constants Assisted-by: Grok:grok-4.6 * Clear process-wide eval breaker bits in STW test Assisted-by: Grok:grok-4.6 * Drop exclusive-held panic that tripped wasm clippy Assisted-by: Grok:grok-4.6 * Fix OrderedDict contains and export Windows BDADDR Assisted-by: Grok:grok-4.6 * Add cmp_to_key and hash-once LRU cache _functools.cmp_to_key now returns KeyWrapper. LRU lookups store the key hash on _lru_list_elem so __hash__ is not called again on hits or eviction. Assisted-by: Grok:grok-4.6 * Allow subclass keywords on list, tuple, and float list.__init__ rejects keywords only when tp_new is still list's. tuple/float.__new__ reject them only when tp_init is still the base's. Assisted-by: Grok:grok-4.6 * Fix CI lint, test re-export, and structseq members Drop the duplicate clear_eval_breaker_for_test re-export. Format structseq imports. Expose struct sequence fields as readonly members so assignment raises "readonly attribute". Assisted-by: Grok:grok-4.6 * Allow subclass keywords on itertools and filter Positional-only constructors ignore extra keywords when a subclass has replaced tp_init, matching list/tuple/float. Assisted-by: Grok:grok-4.6 * Remove text_signature derive parameter Drop the string override on #[pyfunction] and #[pyclass]. Signatures are generated from the Rust parameter list only. Restore inspect expectedFailures that depended on the override. Assisted-by: Grok:grok-4.6 * Rename set contains_method to __contains__ Keep a borrowed contains helper for slots and C-API. The coexist pymethod is named __contains__. Assisted-by: Grok:grok-4.6 * Use MonitoringEvent instead of EVENT_* aliases Drop the unused MonitoringEvents bitflags and the EVENT_PY_START style mask constants. Call sites use the enum and .mask(). Assisted-by: Grok:grok-4.6 * Store warnings filters as PyListRef The list already serializes its elements. Drop the extra mutex around the cached list pointer. Assisted-by: Grok:grok-4.6 * Re-export clear_eval_breaker_for_test after rebase Keep the STW test helper visible without bringing back stop_bit_set. Assisted-by: Grok:grok-4.6 * Fix groupby reentrancy and islice arguments Give _grouper its own tgtkey and take currvalue after the key comparison. Accept __index__ on islice bounds, reject step 0, and drain the source up to stop. Assisted-by: Grok:grok-4.6 * SETREF warnings filters, onceregistry, and defaultaction Keep the last list, dict, or str after the module attributes are deleted by swapping the interpreter cache pointer. Do not store a None fallback for _warnings_context. Assisted-by: Grok:grok-4.6 * Iterate OrderedDict inner dict via next_entry &PyDict is not an iterator after the borrowed-ref signature change. Assisted-by: Grok:grok-4.6 * Remove expectedFailure from testBluetoothConstants Linux now exports BTPROTO_HCI and the rest of the set. Assisted-by: Grok:grok-4.6 * Borrow get_filter arguments as PyObject Match the warn_explicit call site that passes borrowed handles after the internal-helper borrow change. Assisted-by: Grok:grok-4.6 * Fix bool slots and SemHandle safety docs Leave unused bool number slots unset so inspect reports __add__ on int. Document SemHandle::from_raw safety. Assisted-by: Grok:grok-4.6 * Keep sendmsg errors and drop duplicate linecache Replace sendmsg iterable TypeError only. Register REPL source in linecache once per compiled input. Assisted-by: Grok:grok-4.6 * Nest REPL parse or-patterns for clippy Assisted-by: Grok:grok-4.6 * Mark pydoc os.stat signature test expectedFailure Assisted-by: Grok:grok-4.6 --------- Co-authored-by: Lee Dogeon <dev.moreal@gmail.com> |

Fix 33 reproduced fuzzing and static-review defects (#8514)
* mmap: guard move() against dest/src past the mapping size
An offset larger than the mapping made `size - dest` underflow, producing
an out-of-range slice index panic. Check the high side first, as write() does.
Assisted-by: Claude
* exceptions: keep ImportError name/path/name_from out of an empty instance dict
ImportError.__reduce__ unwrapped get_arg(0), which is None when the exception
was constructed with no positional argument, aborting on pickle.dumps(ImportError()).
Fall back to the full args tuple there, and expose name/path/name_from as class
attributes defaulting to None so a bare ImportError() reduces to (cls, ()).
Assisted-by: Claude
* asyncio: stop unwrapping the _current_tasks downcast in current_task()
_asyncio._current_tasks is a reassignable module attribute; the three sibling
functions already degrade gracefully when it is not a dict, current_task() did not.
Assisted-by: Claude
* asyncio: raise TypeError when FutureIter.throw()'s exception class returns a non-exception
exc_type.call() goes through a Python-controlled __new__, so its result can be
any object; the downcast was unwrapped. Report it as a TypeError instead.
Assisted-by: Claude
* sequence: use a fallible reservation for sequence repetition
The guard only rejects a repeat whose per-element size crosses MAX_MEMORY_SIZE,
so (1,) * (10**12) still reached Vec::with_capacity and aborted in the allocator.
Reserve fallibly and surface a MemoryError.
Assisted-by: Claude
* collections: reject an oversized deque repetition with MemoryError
deque * sys.maxsize reached the allocator and aborted with a capacity overflow.
Apply the MAX_MEMORY_SIZE guard the other sequences already carry.
Assisted-by: Claude
* itertools: raise OverflowError for an out-of-range r argument
combinations/combinations_with_replacement/permutations narrowed r with
to_usize().unwrap(), so r=2**64 panicked instead of raising.
Assisted-by: Claude
* math: stream the generic sumprod path instead of collecting both iterables
The big-int path collected each argument into a Vec before multiplying, so an
unbounded iterable exhausted memory. Advance both iterators in lockstep and
accumulate, reporting a length mismatch when only one is exhausted.
Assisted-by: Claude
* _imp: raise TypeError for a second positional argument to find_frozen
withdata is keyword-only and unimplemented; passing it positionally hit an
unimplemented!() and aborted.
Assisted-by: Claude
* _typing: check _idfunc arity before indexing args
_typing._idfunc() with no argument indexed args[0] out of bounds.
Assisted-by: Claude
* exceptions: require a sequence for the ExceptionGroup excs argument
The argument was collected before being validated, so an unbounded iterable
such as itertools.count() exhausted memory. Reject a non-sequence up front.
Assisted-by: Claude
* mmap: treat an inverted find/rfind range as empty
find(b"x", 5, 2) built a slice whose start exceeded its end and panicked.
Assisted-by: Claude
* collections: give deque and defaultdict a GC traverse
Neither type opted into traversal, so a reference cycle through a deque or a
defaultdict was never collected.
Assisted-by: Claude
* itertools: opt the iterator types into GC traverse
cycle and its siblings hold Python references but declared no traverse, so a
cycle built through one of them leaked.
Assisted-by: Claude
* _ctypes: mask an out-of-range int instead of panicking
c_char_p(2**64) and pointer item assignment called .expect() on the narrowing
conversion. Wrap the value to the target width, which is what the C
implementation stores.
Assisted-by: Claude
* hashlib: import _hashlib when a hash module is loaded
The hash object type is a static type owned by _hashlib; calling _md5.md5()
without _hashlib imported hit an uninitialized static type and panicked.
Assisted-by: Claude
* _csv: fall back to the built-in dialect defaults when none is registered
The dialect table is empty until csv.py registers 'excel', so _csv.reader([])
unwrapped a missing entry and panicked.
Assisted-by: Claude
* builtins: reject surrogates in compile()/eval() source instead of panicking
expect_str() panics on a str containing surrogates; convert with try_as_utf8
so eval(chr(0xd800)) raises.
Assisted-by: Claude
* _suggestions: require a list for _generate_suggestions candidates
The argument was collected before validation, so an unbounded iterable
exhausted memory.
Assisted-by: Claude
* lzma: size the filter chain before consuming it
filters= was collected into a Vec before the length check, so an unbounded
iterable exhausted memory. Take the length through the sequence protocol first.
Assisted-by: Claude
* classmethod: opt into GC traverse
staticmethod already declares traverse; classmethod did not, so a cycle through
the wrapped callable leaked.
Assisted-by: Claude
* posix: reject unbounded iterables in posix_spawn and setgroups
argv, setsigdef, setsigmask and setgroups bound an ArgIterable and collected it
before validating, so an infinite generator exhausted memory. Require a
list/tuple for argv, validate signals while streaming, and take setgroups
through the sequence protocol.
Assisted-by: Claude
* _ctypes: size Array slice assignment and _argtypes_ before collecting
Both eagerly collected their argument, so an unbounded iterable exhausted
memory before the length check ran.
Assisted-by: Claude
* sys: propagate the breakpointhook warning failure
warn() was unwrapped, so an unimportable $PYTHONBREAKPOINT under
-W error panicked instead of raising.
Assisted-by: Claude
* structseq: require the sequence argument when constructing a struct sequence
A no-argument construction produced an empty backing tuple, and reading any
named field then indexed out of bounds.
Assisted-by: Claude
* Guard the hash slot dispatch against unbounded recursion
`PyObject::hash` invoked the type's hash slot directly, so an element-wise
`__hash__` following a deeply nested object graph recursed one native frame
per level and overflowed the stack. Wrap the dispatch in `with_recursion`,
matching the repr and rich-compare dispatches in the same file, so
`hash(x)` on a nested tuple/GenericAlias/slice raises `RecursionError`.
Assisted-by: Claude
* genericalias: guard the __parameters__ walk against unbounded recursion
`make_parameters_from_slice` recursed into every list/tuple argument with
nothing counting the frames, so `list[L]` for a self-referential or deeply
nested `L` overflowed the native stack at subscript time. Wrap the descent
in `with_recursion`, which makes the walk fallible; `PyGenericAlias::new`,
`from_args` and `make_parameters` now return `PyResult` and every caller
propagates.
Assisted-by: Claude
* Fix the type confusion in PyAtomicRef's Debug impl
`PyAtomicRef<T>` stores a pointer to a `Py<T>`, as `Deref`, `load_raw`,
`swap` and `Drop` all read it, but `Debug` cast it to a bare `T` and
formatted the object header as payload bytes. For `PyFunction`, whose
`code: PyAtomicRef<PyCode>` has a pointer-chasing `Debug`, that
dereferenced header words and segfaulted.
Cast to `PyObject` instead, which is what `Drop` already does and which
also covers the `PyAtomicRef<PyObject>` and `PyAtomicRef<Option<T>>`
instantiations that have no `Py<T>`.
`_asyncio._enter_task` reached this through `{:?}` in its "Cannot enter
into task" message; format the two tasks with their Python repr, which is
what the message is meant to show.
Assisted-by: Claude
* _sre: disallow instantiating Match
`Match` inherited `object.__new__`, so `M.__new__(M)` produced an instance
whose `regs`/`string`/`pattern` were never filled in by a match run; the
mapping subscript path read them and dereferenced garbage. The type has no
public constructor, so mark it `DISALLOW_INSTANTIATION`, which makes
`M.__new__(M)` raise `TypeError: cannot create 're.Match' instances`.
Assisted-by: Claude
* utils: return the empty repr instead of asserting a non-empty collection
`collection_repr` took the first element with an `.expect()` justified by the
caller's preceding non-empty check. Another thread clearing the collection
between that check and the iteration made the iterator yield nothing and
panicked the worker. Fall back to the caller-supplied empty form, which is
the text those callers already produce for an empty collection.
Assisted-by: Claude
* itertools: advance cycle's index atomically
`cycle.__next__` did `fetch_add(1)` and then reset the index to 0 in a
separate store, so two threads replaying the saved items could both read an
index past the end of `saved` and panic on the slice access. Do the advance
and the wrap in one `fetch_update`.
Assisted-by: Claude
* _ctypes: reject a float argument to a foreign call without argtypes
`conv_param`, the conversion used when `argtypes` is not set, converted its
argument with `try_int`, which goes through `__int__` and so accepts a
float. `libc.strlen(1.5)` therefore passed 1 where the callee expects a
`char *` and the callee dereferenced it. Match `ConvParam`, which does a
`PyLong_Check` and converts nothing: take the branch only for an `int` (or
a subclass, so `True` still converts), and let a float fall through to
"Don't know how to convert parameter".
The branch below it converted a float to a C double, but `try_int` claimed
every float before it could run, so it was dead; `CArgValue::Double`
existed only for that branch and both go. Typed doubles are unaffected —
they travel as `CArgValue::Typed` with code 'd'.
Assisted-by: Claude
* Report the iterator itself from PyIter's traverse
`Traverse for PyIter<O>` delegated to the inherent `PyObject::traverse` of
the object it wraps, so it reported that iterator's referents instead of
the iterator. The iterator's own reference to those referents was then
never subtracted during the collector's reference-subtraction pass, the
referents kept a non-zero gc_refs, and every object reachable from them
was classified as a root.
Any cycle running through a type with a `PyIter` field therefore survived
collection: `map`, `filter`, `zip`, `enumerate`, `reversed` and the
`itertools` iterators all leaked, while the same cycle through a `list`,
`tuple` or `list_iterator` collected. Report the wrapped object, as the
`PyObjectRef`, `PyRef<T>` and `PyStackRef` impls do.
`itertools.tee` still leaks: its shared buffer is a `PyRc<PyItertoolsTeeData>`
rather than a Python object, so the collector cannot see through it.
Assisted-by: Claude
* Remove the obsolete expectedFailure on test_code_module.test_unicode_error
Compiling a source string containing a lone surrogate now raises
UnicodeEncodeError, so the test passes.
Assisted-by: Claude
* itertools: reserve the combination indices fallibly
`combinations` and `combinations_with_replacement` built their index vector
with an infallible allocation, so an `r` that passes the ssize_t check but
does not fit in memory aborted the process instead of raising MemoryError.
Assisted-by: Claude
* Apply the struct sequence constructor's dict argument
`structseq(sequence, dict)` discarded its second argument, so the hidden
fields past `n_sequence_fields` — `tm_zone`, `st_atime` and friends — were
always None when constructed directly or restored from a `(sequence, dict)`
pickle, and a non-dict second argument was accepted silently.
Take the dict, require it to be a dict, and fill the hidden slots the
sequence did not cover from it. A key that names a field the sequence
already supplied, or no field at all, is now a
"got duplicate or unexpected field name(s)" TypeError instead of being
dropped. Both arguments are bindable by name, as `sequence` and `dict`.
`os.stat_result` and `os.statvfs_result` did not accept a second argument
at all; they and `time.struct_time` now share the parsing.
Assisted-by: Claude
* _imp: report the argument count in find_frozen's arity error
Assisted-by: Claude
* Add regression tests for the reproduced crashers
One case per catalog entry, each asserting the behavior the fix produces:
recursion guards, the memory-unsafety sites, the overflow and unbounded
allocation guards, the eager-collection rejections, the unwrap sites, and
the cycles the collector now breaks. Every expected value was checked
against CPython 3.14.
Assisted-by: Claude
* Tolerate a changed-size RuntimeError in the set repr stress test
The mutator and reader threads race on purpose; a "changed size during
iteration" RuntimeError is a valid outcome of that race and should not fail
the test. The panic it guards against is not.
Assisted-by: Claude
* Move the crash regression tests into per-module snippets
crash_regressions.py collected every reproduced crasher in one file. Split it
into the snippet for the module each case exercises, and add stdlib_gc.py,
stdlib_asyncio.py, stdlib_lzma.py, stdlib_threading_set_repr.py and
stdlib_threading_itertools_cycle.py for the cases with no existing home.
The suite runs every snippet under the host CPython too, so the checks only
RustPython raises are guarded by sys.implementation.name: the hash and
__parameters__ recursion depth, and the deque repeat overflow. The float
ctypes argument accepts either TypeError or ctypes.ArgumentError.
