* address review: negative defaults, to_bytes signed, get_self, fstat
- python_default_repr renders negated int/float literals and looks
through parentheses and groups.
- int.to_bytes signed is ArgIntoBool again, so any object is accepted
by truthiness; its signature default stays False via py_default.
- PyNativeFunction::get_self falls back to the module object.
- os.fstat has its own FromArgs with a single fd parameter instead of
reusing stat's arguments.
Assisted-by: Claude:claude-opus-5-5
* address review: literal default rendering and fstat supports sets
- Literal defaults are rendered by python_literal_repr, which recurses
through negation, parentheses and groups, so `-(1)` renders `-1`.
- Float literals without a dot or exponent, such as `1f64`, render
with a trailing `.0`.
- os.fstat is removed from supports_fd, supports_dir_fd and
supports_follow_symlinks.

* Store instance slots as atomic object pointers
PyMemberDef now carries type, offset, and flags. Slot values are
atomic PyObject pointers with try-incref reads, so a concurrent
store cannot free the memory under a reader. Objects placed in a
slot stay published until QSBR reclaims them.

* Reject over-long digit strings before parsing
A pure ASCII digit string longer than the int digit limit now fails

* Restore MemberKind for member type codes
The VM stores the member type as an enum whose discriminants match

* Mark MemberKind::from_i32 as must_use
Assisted-by: Grok:4.7
* Compose native text signatures at compile time from FromArgs
FromArgs gains a PARAMS const describing its Python parameters.
The derive builds the whole internal doc, `name(sig)\n--\n\ndoc`,
in a const context from those params, and `__text_signature__` /
`__doc__` parse it from the doc. The macro-time string path and the
runtime sig_parts composition are removed.
Signatures follow clinic conventions: `$module` for module functions,
Rust literal defaults rendered as Python reprs, other defaults as
`<unrepresentable>`, and a new `#[pyarg(py_default = "...")]` for the
few fields whose Rust default differs from the Python one. The
`#[pyarg]` keys are documented on the FromArgs derive.
Module functions keep their module object and return it from
`__self__`. PyNativeFunction now traverses its references.
os.stat, os.mkdir, os.listdir, os.open, dict.fromkeys, round, sorted,
int.to_bytes and bytes.hex take arguments matching their signatures.

* Update builtin_signature snippet and fix mkdir on Windows
round and sum now report their FromArgs parameters, so the snippet
asserts their signatures instead of their absence. sum's start is a
PyObjectRef defaulting to int 0 with py_default "0". mkdir reads
dir_fd only on platforms that use it.
Assisted-by: Claude:claude-opus-5-5

Internal functions that took PyObjectRef or PyRef<T> by value but only
borrowed it (reported by clippy::needless_pass_by_value) now take
&PyObject or &Py<T>. Callers pass a borrow instead of an owned handle;
61 caller-side .clone()/.to_owned() calls made only to pass the argument
are removed. Where a converted body already cloned the parameter, that
.clone() became .to_owned().
Functions with #[py*] attributes, trait methods, and functions whose
signature is fixed by a function pointer, getset or slot wrapper type are
unchanged.
PyFloat_FromString in crates/capi passes the borrowed object to
parse_float_from_string without taking an owned reference.

Parameters, return types, closure annotations, Fn and Iterator bounds,
trait methods and struct fields that borrowed an owning handle now borrow
the object: &PyObjectRef -> &PyObject, &PyRef<T> / &PyXxxRef -> &Py<T>.
Existing .clone() calls on those values became .to_owned().
- Move PyTuple::extract_tuple into impl Py<PyTuple>; FromPyTuple::from_pytuple
takes &Py<PyTuple>.
- DictIter and IntoIterator for &PyDict use &Py<PyDict>; apply_shared_ns

tuple helpers take iterators over &PyObject; callers map with |o| &**o.
- Return types changed: TypeNamespace::as_dict, Context::cached_int,
struct_error_type, PyBoundMethod::function_obj/self_obj,
AsRef for ArgIndex. as_dict, function_obj and self_obj are no longer

(#2410), when RustPython had no __text_signature__ for builtins. It has
one now, so --signature and --doc cover functions and methods written in
Rust. Modules with a mismatched signature go from 45 to 134, and 160 of
the 710 mismatched items are ones CPython itself cannot parse, which the
--signature listing already skips.
__builtins__ is no longer compared. inspect.signature() evals defaults in
the owning module's namespace and eval() adds __builtins__ there, so
CPython's builtins module gained one after list.index was inspected and
it showed up as missing.

* Scan the members of native classes in each module
A module was only compared one level deep, so a native class counted as
present whatever its methods were. Classes a module owns and that are
not Python-defined are now opened too, and their own members are
compared as "Class.member": 438 classes and 4,833 members, 1,033 of
which have a signature --signature reports.
A class is native when it has no __firstlineno__, which a class
statement records, and no Python functions of its own, which rules out
namedtuple-style classes made by type(). BUILTIN_TYPES moves to module
level so the builtin types are not reported twice, an alias like
array.ArrayType is skipped, and CPython's __annotations_cache__ and
__vectorcalloffset__ are left out.
RustPython follows the CPython list instead of deciding again. A member
only inherited is listed as missing with "(inherited)", as builtin type
methods are. A class missing here, or implemented as something else such
as _sha3's hash functions, is reported by its own line only.

* Report a module that exists but cannot be imported
dir_of_mod_or_error() ran dir() on the exception import_module() returns,
so a failed import looked like a module whose every item is missing:
sqlite3 alone filled 198 of those lines, and CPython's own _ios_support
was compared as a module holding ImportError's attributes. Returning the
exception reaches the "exists but not importable" line that was already
written for it, and drops 529 lines from "stdlib items".

* Compare a module's own docstring
extra_info() reports a docstring for callables, and a module is not one,
so the __doc__ item both sides record was None and a module docstring
never counted as a mismatch. Reading it with getdoc(), the way a
callable's is read, brings 221 module docstrings into the comparison.
sys is the one that differs; base64 and imaplib differ here only
because their Lib copies track 3.14.7 while this run used 3.14.6.
Non-callables keep reporting None. getdoc() on a plain value answers
with its type's docstring, which would turn every string constant into
a mismatch.

* Decide a member's ownership by the class dictionary
attr_is_not_inherited() compared the attribute's value with each base's.
That took an inherited classmethod for the class's own, since a bound
method compares unequal across classes, and dropped an own attribute
whose value matched a base's default None: 394 of CPython's in all,
ast.FunctionDef.returns among them. On the RustPython side it called
AttributeError.name, a class attribute set to None, inherited.
Ownership now means the class dictionary holds the name. An inherited
member is reported only when what it resolves to differs from CPython's
own, so dict_items.__doc__, a slot CPython fills with None that
RustPython resolves to None without one, stays quiet. "(inherited)"
lines drop from 196 to 54, and ast.alias.end_lineno is among the real
gaps that appear.

Return the kernel thread id (gettid / pthread_threadid_np /
GetCurrentThreadId). threading.get_native_id and Thread.native_id
follow once the function exists.

malachite-bigint 0.12.0 was published while the workspace pinned 0.11.0.
pymath requires malachite-bigint = "0", so a fresh resolve picks 0.12 for
it and leaves the workspace on 0.11, putting two incompatible BigInt types
in one graph. example_projects carry no lockfile and resolve fresh.
malachite-q and malachite-base move with it. No source change is needed.

`char_to_decimal` carried its own sorted table of 590 decimal digit
characters, added in #5643 because `common` had no way to reach the
Unicode numeric data at the time: it lived in `stdlib`, which sits above
`common` in the dependency graph. The table's own comment said as much —
"this should probably live in a crate like unic or unicode-properties".
#8211 extracted that data into `rustpython-unicode`, below `common`, and
made `common` depend on it, so the table can now be dropped in favour of
`Ucd::decimal` — the same source `unicodedata.decimal` consults.
This fixes a CPython incompatibility. The table was last updated for
Unicode 10; the bundled UCD is Unicode 17, which has 180 more decimal
digits across 18 scripts (Hanifi Rohingya, Wancho, Tangsa, Ol Onal,
segmented digits and others). Those were rejected by `int()` and
`float()` even though `unicodedata.decimal` knew their value:
>>> int('\u{10D33}') # HANIFI ROHINGYA DIGIT THREE
ValueError # CPython: 3
>>> unicodedata.decimal('\u{10D33}')
3
All 590 characters the table covered keep their previous value, so
nothing that already worked changes, and the two lookups can no longer
drift apart on a future Unicode update.
The lookup costs about 1.5ns more per non-ASCII character, since it reads
a property trie and a value table instead of binary-searching one 2.4KB
array: `int()` over a 4000-digit non-ASCII string goes from 12.2 to
13.6 ns/char. ASCII input never reaches it — the sole caller,
`transform_decimal_and_space_to_ascii`, returns early for ASCII strings —
so ordinary numeric parsing is unaffected.

decompress_chunks reports whether the codec signalled LZMA_STREAM_END,
and it short-circuits when the chunker has nothing left to feed. That
early return answered "the stream ended" for the case where no input was
supplied at all, so LZMADecompressor.decompress(b"") claimed a finish the
decoder had never signalled.
The caller latches that answer with `self.eof |= stream_end`, which only
ever flips eof on. A single empty call therefore finished the object for
good: needs_input went false and every later call was rejected by the
`if self.eof` guard with EOFError, before a single compressed byte had
been seen. CPython leaves eof false and needs_input true, and accepts
compressed data handed over by a later call.
d = lzma.LZMADecompressor()
d.decompress(b"") # d.eof was True, now False
d.decompress(blob) # was EOFError, now b'data'
The zlib engine returns false from the same short-circuit; lzma had
drifted away from it. bz2 was fixed incidentally by #8638 when its engine
moved into crates/common, so only lzma needed a code change.
Verified on macOS arm64 against CPython 3.14.7: the script from the issue
now prints the documented "False True" and b'data' for both
decompressors. test_decompressor_chunks_empty in Lib/test/test_lzma.py
covers exactly this and no longer needs its expectedFailure marker. The
added engine test is named after the zlib one that already existed and is
mirrored into bz2, so all three engines stay pinned to the same
behaviour. test_lzma, test_bz2, test_zlib, test_gzip, test_tarfile,
cargo test --workspace, cargo fmt --check and cargo clippy
-p rustpython-common --all-features --all-targets -D warnings are clean.
Fixes#8637
