Jeong, YunWon cb0f3b012b Add a native _zoneinfo module (#8915)
* Add a native _zoneinfo module

ZoneInfo reads TZif tuples from zoneinfo._common.load_data. The stdlib
module implements utcoffset, dst, tzname, fromutc, and the zone cache.
whats_left compares that class. Cache tests no longer expect failure.

Assisted-by: Grok:grok-4.7

* Fix ZoneInfo layout and keep its cache on the module

utcoffset, dst, and tzname take the object. Zone data is boxed so the
payload lines up with tzinfo on 32-bit. The strong, weak, and timedelta
caches live on each interpreter's _zoneinfo module.

Jeong, YunWon d54a4c5932 Set builtin __doc__, __module__, and datetime signatures (#8897)
* Set builtin __doc__, __module__, and datetime signatures

Expose empty doc-db member entries as ''. Heap __dict__ and __weakref__
getsets carry their descriptor docs. Member repr uses the qualified
type name.

__module__ is collections for the deque iterators, _csv for Dialect,
ctypes for ArgumentError and CField, _lzma for LZMAError, operator for
the getter types, pickle for PickleBuffer, _ssl for MemoryBIO,
SSLSession, _SSLContext and _SSLSocket, weakref for the proxy types,
and posix (nt on Windows) for times_result and uname_result.
unicodedata's copied UCD functions set __module__ to unicodedata.

_testinternalcapi function docs and weakproxy.__str__ use the stored
text. datetime replace defaults render as unchanged, __replace__ is
($self, /, **changes) and binds through replace, now defaults tz to
None, and fromisoformat and tzinfo methods name the parameter object.

Jeong, YunWon 7f314dd02b Remove unused PyLease; skip flaky httpservers test on macOS (#8821)
* Remove unused PyLease

PyLease wrapped a read guard over the object's type when `typ` was a
`PyRwLock<PyTypeRef>`. Its last users, `class()` and `lease_class()`,
went away when `typ` became a `PyAtomicRef<PyType>` (#3828). Its field
is private and it has no constructor, so it cannot be built anywhere.

Assisted-by: Claude Code:claude-opus-5-5

* Skip test_large_content_length_truncated on macOS

The test sets the CGI handler timeout to 1ms. That timeout also bounds
reading the request line, so when the client has not sent the request
within 1ms the server logs "Request timed out" and closes the
connection. The client then gets ConnectionResetError or
BrokenPipeError. This reproduces on macOS with both RustPython and
CPython 3.14.6. The skip was removed in #8759 after Linux-only
repeats.

Jeong, YunWon 3c654204f5 Match native text signatures to CPython names, kinds and defaults (#8815)
* Render CPython defaults in generated text signatures

Arguments whose default rendered as `<unrepresentable>`, while the
same callable has a representable default in CPython, now render that
default:

- Where the Rust value can be a literal, the argument becomes a plain
  field with `default = <literal>`.
- The remaining cases keep their Rust default and add `py_default`
  with a comment. These are wrappers such as ArgIntoFloat or
  ArgIntoBool, values that need the VM, enums, and Option where None
  means another value.

Byte string literals render as Python bytes. A function registered
under several names gets an internal doc per name, so its __doc__ no
longer carries the signature header.

Removed expectedFailure from test_pydoc tests that now pass.

* Derive signature defaults from typed Rust values

Param.default is now a DefaultRepr rendered by the const writer.
Literals, integer and bool constants become typed defaults, and other
default expressions use the type's const fn py_default. A bare
`optional` renders as None, so `default = None` rewrites are reverted.

Address review comments: zlib max_length defaults, get_ca_certs
binary_form keyword, getpeercert der, WASM ssl certificate keywords,
fstatvfs fd-only, and _sre endpos shown as sys.maxsize.

* Generate class constructor text signatures at compile time

A #[pyclass] impl composes the type's internal doc from the Args of
its Initializer or Constructor, so type.__text_signature__ and
inspect.signature work for native classes. __doc__ stays the plain
doc. Struct sequences get (iterable=(), /) and __reduce__ (self, /).
Hand-parsed constructors are converted to FromArgs structs, and
_weakref.proxy is split from ProxyType.

kinds and <unrepresentable> defaults where CPython's signature is

...). getaddrinfo accepts keyword arguments. whats_left treats a

* Distinguish OptionalArg and Option in signature defaults

An `optional` field's signature default now comes from its type:
Option<T> renders None, while OptionalArg<T> (a missing argument that

missing argument behaves exactly like None become Option<T>; fields
whose missing state differs keep OptionalArg. Redundant
py_default = "<unrepresentable>" entries are removed.

OptionalOption and OptionalArg<Option<T>> fields that treat a missing
argument like None become Option<T> with #[pyarg(optional)], which renders
=None in the text signature. Plain optional parameters of that kind move
into small FromArgs structs. Uses where missing and None differ (reduce
initial, StringIO newline, TextIOWrapper.reconfigure, set_asyncgen_hooks)
keep OptionalOption.

* Render ::NAME defaults by name and restore named constant defaults

- default = ::NAME writes NAME into the text signature and stores
  Into::into(NAME) as the Rust value.
- A one-field tuple-struct argument pattern such as Fildes(fd) names the
  parameter after its binding, so fcntl and termios keep destructuring.
- zlib, lzma, syslog, mmap and select defaults use their named constants
  again instead of literals or <unrepresentable>.

* Build literal defaults from Python values and type <unrepresentable>

- default = LIT on a non-primitive field converts the literal through
  ToPyObject and TryFromObject when the argument is missing, so object
  fields no longer need a vm expression plus a matching py_default.
- A bare default on a primitive integer, bool or float field renders its
  zero value.
- DefaultRepr::Unrepresentable replaces the <unrepresentable> text, and
  py_default = "<unrepresentable>" is a compile error.
- pyexpat.ParserCreate distinguishes a missing intern from intern=None,
  mmap AccessMode renders its value, and sqlite blobopen names rowid.

* Resolve native docstrings from the doc database at compile time

- rustpython-doc stores its table as a sorted const slice with const fn
  lookups (get, get_attr, class_attr_doc) instead of a phf map, and the
  update-doc-db workflow emits that form.
- Class, method, getset, module function and struct sequence docs, and
  per-class slot wrapper docs, are chosen by const lookups in the derive
  output. The database text wins over Rust doc comments.
- Macros reach the table through rustpython_vm::__exports, so only the vm
  depends on rustpython-doc.
- Remove expectedFailure markers from doctest and pydoc tests that pass.

Joshua Megnauth c8f1ab7fbc ucd: Parse Unihan data for 3.2.0; unmask numeric test (#8783)
* ucd: Parse Unihan data for 3.2.0; unmask test

Python's 3.2.0 path uses the Unihan data for supplementary numeric
values. The Unihan data isn't bundled with the "full" data which means
we have to parse it ourselves. The full data is large, so I compressed
it with zlib.

AI disclosure: I asked an LLM to elaborate on why the full Unicode 3.2.0
data precludes \u5793. It explained that the code point is part of
Unihan. I wrote the parser myself. I linted the zlib snippet with AI.

Jeong, YunWon 7cd4a54e1c Compose native text signatures at compile time from FromArgs (#8807)
* 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.

hyoinandout 4c7cc0a30c lzma: treat empty input as a no-op, not end of stream (#8752)
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.

* pyexpat: add UseForeignDTD, fix silently swallowed handler exceptions

genshi's XML template loader (bm_genshi) called xmlparser.UseForeignDTD(),
which pyexpat.rs didn't implement, raising AttributeError. Add it as an
accepted no-op: the pyexpat module here wraps the pure-Rust xml-rs crate
(not real libexpat), which has no hook for splicing in a foreign DTD.

Root-causing the resulting bug also uncovered why genshi's template
generate()/render() produced empty output instead of erroring: do_parse's
invoke_handler swallowed every exception raised by a Python callback
(handler.call(...).ok()), and genshi's expat callbacks fail immediately
by reading `parser.CurrentLineNumber`/`CurrentColumnNumber`, which
pyexpat.rs never exposed. The AttributeError was silently discarded,
so no start/end/text events ever reached genshi's queue.

Fix both: propagate handler exceptions out of Parse()/ParseFile() (matching
libexpat/CPython semantics), and add CurrentLineNumber/CurrentColumnNumber/
CurrentByteIndex as read-only attributes backed by xml-rs's per-event
TextPosition (byte index is derived from it and is exact for ASCII
documents). This also fixes test_minidom's
testExceptionOnSpacesInXMLNSValue, previously an expected failure because
the ValueError from an invalid xmlns value was swallowed the same way.

PositionTest in test_pyexpat.py checks byte-exact expat semantics (token
*start* position) that xml-rs's *current parse cursor* position can't
reproduce exactly, so that one test is now marked an expected failure.

* pyexpat: support multi-chunk Parse()/ParseFile() feeds

bm_xml_etree failed with AssertionError: missing end tags from
TreeBuilder.close(), because xml.etree.ElementTree reads and feeds large
documents to XMLParser.feed() in ~64KB chunks (and xml.sax's
IncrementalParser and ElementTree's XMLPullParser do the same). Each
Parse()/ParseFile() call built a brand-new xml-rs EventReader from only
the bytes passed in that call, discarding all parser state between calls.
When a chunk boundary fell in the middle of an element, the fragment
parsed by itself was invalid/incomplete XML, so xml-rs silently errored
out (matching this module's existing "ignore stricter xml-rs errors"
behavior) and the corresponding start/end events were dropped entirely
-- not just delayed.

xml-rs has no API to resume a parser across separate Read sources, so
instead each call now appends the new chunk to a persistent buffer and
re-parses the buffer as a whole, replaying only the events at or beyond
the count already dispatched in previous calls (dispatched_events). This
also makes position tracking (CurrentLineNumber/Column/ByteIndex) correct
regardless of how the input was chunked. Trade-off: each Parse() call is
now O(size fed so far), so a document delivered in many small chunks is
parsed several times over; acceptable for correctness but noticeably
slower than a true incremental parser for pathological chunk sizes.

This also fixes several previously-xfailed tests that depend on
incremental feeding: test_xml_etree.py's XMLPullParserTest (test_events,
test_feed_while_iterating, test_simple_xml, test_simple_xml_chunk_22,
test_simple_xml_with_ns) and ElementTreeTest.test_parseliteral, plus
test_sax.py's ExpatReaderTest (test_expat_entityresolver_default,
test_expat_incremental, test_expat_incremental_reset) -- their
expectedFailure markers are removed. test_simple_xml_chunk_1/_chunk_5
(1- and 5-byte chunks) still fail and remain xfail: at that granularity
xml-rs's stricter-than-expat tokenizer errors on some intermediate
prefixes that libexpat tolerates.

* pyexpat: drive a single background EventReader for true incremental Parse()

8802451f3 fixed multi-chunk Parse()/ParseFile() feeds by accumulating every
fed byte and re-parsing the whole buffer from scratch on each call, which is
O(total bytes) per chunk -- quadratic in document size. xml-rs's EventReader
has no API to pause/resume across separate Read sources, so instead one
EventReader is now driven to completion on a dedicated background thread fed
through a condvar-backed queue (FeedBuffer/FeedReader); Parse()/ParseFile()
push their chunk, wake the thread, and drain (on the calling thread only)
whatever events that unblocks, stopping once the thread reports it is
blocked waiting for more input. Handlers always run on the calling thread.
A handler exception stops dispatch without tearing down the stream, so the
next Parse() resumes where it left off, mirroring libexpat. CurrentByteIndex
is now computed incrementally per line (with an amortized per-query cursor,
needed since real documents are often a single very long line) instead of
scanning the whole buffer. ParserCreate() never spawns a thread; one is
spawned lazily by the first Parse()/ParseFile() call, and dropping the
parser always stops and joins it.

Fixes test_xml_etree{,_c}'s test_events_comment, previously xfailed because
the old whole-buffer replay lost top-level comment events across feeds.

Measured (M4 Pro, release build):
- Scaling (ElementTree.parse, newline-separated doc): new backend 1/4/16 MB
  = 0.15/0.61/2.35s (linear); CPython 3.14 same file = 0.015/0.055/0.23s.

* pyexpat: add a Sync fallback backend for targets without threads

2f58e9531 made pyexpat always drive its EventReader on a background
thread (ParserStream::spawn), panicking via .expect() if the thread
couldn't be spawned. pyexpat is registered unconditionally, including
on wasm32, where std::thread::spawn always fails at runtime, so the
first Parse() call panicked there.

Introduce a Backend enum: Backend::Threaded (the existing ParserStream)
on targets that can spawn threads, and a new Backend::Sync, the
accumulate-and-reparse implementation from 8802451f3, used on wasm32
and as a runtime fallback if spawning a thread ever fails. Both share
LineTracker for identical CurrentLineNumber/CurrentColumnNumber/
CurrentByteIndex and handler/error semantics.

Fixed two correctness bugs while porting the Sync backend forward:
marking the parser permanently "finished" as soon as a from-scratch
reparse happened to reach EndDocument (which can be a false positive
on a not-yet-complete buffer, e.g. right before epilog content
arrives) rather than only on the caller's real isfinal signal; and
counting that same EndDocument towards the dispatched-event index,
which could make a real event land on an index a later, longer reparse
had already skipped past. Verified by force-selecting Backend::Sync
under a test-only env var (removed) and diffing its output against
Backend::Threaded for the xml/sax/etree/plistlib/xmlrpc test suites
and a 2MB document fed in 1KB chunks.

* _pickle: native Pickler, Unpickler and PickleBuffer

Adds `crates/stdlib/src/pickle.rs`, a native `_pickle` implementing
Pickler, Unpickler, PickleBuffer, PicklerMemoProxy/UnpicklerMemoProxy,
dump/dumps/load/loads and the PickleError family, so `Lib/pickle.py`
stops falling back to `_Pickler`/`_Unpickler`.

Protocols 0-5 are supported and produce byte-identical output to the
pure-Python pickler, including framing for protocol >= 4, memoization,
`fast` mode, dispatch_table, reducer_override, persistent_id /
persistent_load, find_class with `_compat_pickle` fix_imports, buffer
callbacks and out-of-band protocol 5 buffers. This also turns on
`pickle.PickleBuffer`, which RustPython did not have before.

Speedups over the pure-Python implementation (best of 5, us/op):
pickle 835 -> 21 (39x), pickle_list 525 -> 4.4 (119x),
pickle_dict 4018 -> 32 (125x), unpickle 630 -> 24 (26x),
unpickle_list 317 -> 5.0 (63x). CPython 3.14's C accelerator runs the
same workloads 1.5-2.9x faster than this.

test_pickle now runs 1008 tests (was 470) since the C-implementation
test classes are enabled; test_pickle, test_pickletools,
test_picklebuffer are green and 22 obsolete expectedFailure markers are
removed.

* pyexpat: make the threaded backend fork-safe

fork() only keeps the calling thread. test_platform's
test_mac_ver_with_fork crashed the child with SIGTRAP: plistlib parses
a plist through pyexpat (spawning a background parser thread) before
os.fork(), then parses again in the child. Bisecting away every other
explanation (a plain threading.Thread survives the same fork fine,
since it goes through this VM's own fork-safe thread bookkeeping)
showed the crash is not from touching the *inherited* ParserStream
(already joined by refcounting before the fork in this repro) but from
spawning a *brand new* parser thread from the child, which reliably
crashed during the new thread's own startup.

Register a pthread_atfork child hook (lazily, the first time a parser
thread is spawned) that sets a permanent, process-wide flag the
instant this process is ever the child of a fork(). Once set:
- ParserStream::try_spawn refuses to spawn any further thread and
  Backend::new falls back to Backend::Sync instead, exactly as on
  targets that cannot spawn threads at all.
- Feeding an inherited Backend::Threaded raises a clear ExpatError
  instead of touching its FeedBuffer/channel (whose mutex/condvar may
  look held by a thread that no longer exists), and dropping it leaks
  its JoinHandle/buffer/channel via ManuallyDrop rather than joining or
  destroying them, since even destroying a POSIX mutex that looks held
  is undefined behavior.

The parent is unaffected: the pthread_atfork hook only runs in the
child. Verified with a 200-iteration fork stress test (fresh parsers
and parsers forked mid-parse) and the full test_platform/xml/fork/
subprocess/multiprocessing_fork test modules.

* pyexpat: implement name interning via self.intern, matching libexpat

self.intern (an always-present dict by default) was stored but never
consulted; every StartElement/EndElement/attribute name allocated a
fresh PyStr even when the same tag or attribute name repeated across
many sibling events. Wire it up the way libexpat does
(PyDict_SetDefault(self->intern, name, name)): element and attribute
*names* are now memoized so a repeated name reuses the same PyStr
object (and its cached hash) instead of reallocating and rehashing.
Attribute values are left out of the cache, same as libexpat.

This fixes test_pyexpat's previously-xfailed InterningTest.test, which
asserts object identity across repeated StartElementHandler/
EndElementHandler calls.

Measured on the pyperformance xml_etree parse/iterparse/generate/
process variants: no measurable wall-clock change (the dominant cost
there is Python-level TreeBuilder/Element bytecode execution and
thread hand-off, not name allocation), so this is a correctness/
feature-completion fix rather than a throughput win for that
benchmark; kept because it is a real, previously-inert compatibility
gap and is otherwise free.

itertext, copy/deepcopy/pickle state) with CPython's lazily created
attrib dict and deferred text join, is subclassable, weak-referenceable
and GC-traversable, and drops every displaced object after releasing its
lock so a __del__ can re-enter safely.

xml_etree, best of 3 (s): parse 1.64 -> 1.14, iterparse 0.68 -> 0.54,

* _elementtree: native TreeBuilder and XMLParser

TreeBuilder keeps CPython's element/data/tail bookkeeping in Rust,
including the pull-parser event hooks _setevents installs. XMLParser

methods, so a start or end tag reaches the builder without a Python
frame: the universal-name cache, attribute dict and TreeBuilder call all
happen in Rust when the target is our own builder, while foreign targets
still go through the documented start/end/data/comment/pi protocol.
ElementTree.parse() also picks up the _parse_whole fast path.

xml_etree, best of 3 (s): parse 1.14 -> 0.53, iterparse 0.54 -> 0.28,
generate 0.25 -> 0.24, process 0.16 -> 0.16. Against the pure-Python
baseline that is parse 3.1x, iterparse 2.4x, generate 1.8x, process

* pyexpat: stop rescanning the whole line per position query

LineTracker converted a TextPosition column to a byte offset by
validating and decoding its entire buffered line tail on every query,
and appended fed bytes to that tail one at a time. On a document that is
one long line -- what xml.etree.tostring() writes, and what the
xml_etree benchmark parses -- the tail is the whole read-ahead, so a
per-event lookup became quadratic. Walk only the characters the query
actually asks for, over the deque's two halves in place, and record fed
bytes a line at a time. Byte indices are unchanged.

* pyexpat: don't let a stale NeedMore end a Parse() early

The parser thread reports NeedMore when it finds the feed buffer empty
and parks. If it reached that point before the chunk Parse() was about
to push became visible -- which it does whenever the thread happens to
be scheduled first, so more often under load -- pump() consumed that
report as if it answered the new chunk and handed control back to Python
having dispatched nothing, silently losing the whole document.

Stamp each NeedMore with the push count observed when the buffer was
found empty and ignore reports older than the push being pumped. The
push notifies the condvar under the same mutex the report was sent
from, so the parser thread is guaranteed to wake and report again.

Fixes an intermittent failure of test_pyexpat's InterningTest under
parallel load (about 5 losses per 20000 parses before, none after).

* Add inline values flags and special-method lookup

lookup_maybe_method clears AttributeError from descr_get.
slot_tp_richcompare treats a miss as NotImplemented.
hackcheck rejects object.__setattr__ on types.
Heap types with a managed dict and itemsize 0 get
INLINE_VALUES; _testinternalcapi.has_inline_values
reports the valid bit.
super is a base type; subclass __get__ binds the instance.
__classcell__/__qualname__ may share a name with a slot.
Unset member access uses the type's fully qualified name.

slot_tp_new looks up __new__ through descr_get.
is_subtype walks the stored MRO without an identity shortcut.
__slots__ names are sorted so __class__ assignment matches.

Honor explicit pseudo flags when generating opcode metadata so
SETUP_FINALLY/CLEANUP/WITH keep HAS_ARG after regeneration.

Complete the _testinternalcapi hamt mapping: identity on
set/delete, richcompare, weakrefs, subscript, contains, and
length-bearing iterators.

Fire RAISE/STOP_ITERATION for FOR_ITER StopIteration, and skip
both END_FOR and POP_ITER for the exhausted-branch destination.

Assisted-by: Grok:grok-4.6

* Skip FOR_ITER RAISE for sequence iterators

List/range/tuple exhaustion matches FOR_ITER_LIST/RANGE/TUPLE and
must not emit a monitoring RAISE. That event stopped pdb's

Hanjeong Lee df653cea69 Name generated signature parameters the way CPython names them (#8725)
* Leave Rust-only name decoration out of a generated signature

A leading underscore marks an argument Rust sees as unused and `r#`
escapes a Rust keyword. Neither describes the parameter a Python caller
passes, and `r#` is not valid Python, so `inspect.signature()` rejects
any signature carrying one.

Reporting the bare name fixes _sre.template, select.epoll.__exit__ and
bytearray.__reduce_ex__ without touching them, and lets a method name a
parameter after a Rust keyword.

A parameter CPython itself names with a leading underscore, such as
compile's `_feature_version`, reaches Python through a FromArgs field,
which this never sees.

Assisted-by: Claude Code:claude-opus-5

* Name builtin type parameters the way CPython names them

A generated __text_signature__ reports the Rust parameter name, so a
name chosen for Rust reaches anyone reading help() or inspect. Rename
the ones CPython describes differently: list.pop's `i` becomes `index`,
list.count's `needle` becomes `value`, __format__'s `spec` becomes
`format_spec`, bytes.strip's `chars` becomes `bytes`, and
object.__reduce_ex__'s `proto` becomes `protocol`.

Left alone are the parameters CPython reports as `object` or `unused`.
Those are synthesised from the METH_* flags rather than named: CPython
reports slice.indices as ($self, object, /) while its own docstring
calls the argument len.

Assisted-by: Claude Code:claude-opus-5

* Name os parameters the way CPython names them

os.read's `n` becomes `length`, os.lseek's `how` becomes `whence`,
os.kill's `sig` becomes `signal`, os.stat's `file` becomes `path`, and
os.putenv's `key` becomes `name`, among others.

os.chmod is left alone. It reports (path, dir_fd, mode, follow_symlinks)
while the call binds mode second and takes follow_symlinks by keyword, so
the order and the kind are wrong rather than the names, which a rename
cannot fix.

os.fstatvfs is left alone too: it shares one Rust function with statvfs,
which CPython names `path`, so the two aliases cannot report different
names.

Assisted-by: Claude Code:claude-opus-5

* Name sys parameters the way CPython names them

sys.excepthook's (exc_type, exc_val, exc_tb) become (exctype, value,
traceback), sys._getframe's `offset` becomes `depth`, sys.intern's `s`
becomes `string`, and sys.settrace's `tracefunc` becomes `function`.

sys._clear_type_descriptors takes the name CPython gives it, which
Rust spells r#type.

Assisted-by: Claude Code:claude-opus-5

* Name vm stdlib parameters the way CPython names them

deque.rotate's `mid` becomes `n`, deque.extend's `iter` becomes
`iterable`, _sre.ascii_tolower's `ch` becomes `character`,
_operator.neg's `pos` becomes `a`, signal.alarm's `time` becomes
`seconds`, and codecs.register_error's `name` becomes `errors`.

gc.collect and charmap_build keep theirs. Their argument is a FromArgs
struct or a PosArgs bundle, so the reported name is the binding rather
than a parameter, and renaming the binding would only disguise that.

Assisted-by: Claude Code:claude-opus-5

* Name stdlib crate parameters the way CPython names them

unicodedata.category's `character` becomes `chr`, math.isqrt's `x`
becomes `n`, cmath.polar's `x` becomes `z`, struct.calcsize's `fmt`
becomes `format`, binascii.crc32's `init` becomes `crc`, zlib.adler32's
`begin_state` becomes `value`, and array.append's `x` becomes `v`.

array.fromunicode's parameter is `ustr`, which cspell has to be told
about.

array.__deepcopy__ keeps `_memo`, which the generator now reports as
`memo`; CPython calls it `unused`, a name synthesised from METH_O rather
than chosen.

Assisted-by: Claude Code:claude-opus-5

* Name BaseExceptionGroup.split's parameter the way CPython names it

CPython calls the argument of split and subgroup `matcher_value`.

Assisted-by: Claude Code:claude-opus-5

* Strip a generated parameter name with unraw and one prefix check

syn already removes r# through IdentExt::unraw, the way from_args.rs
does for a field name. The empty-name guard never ran: a bare `_` is
Pat::Wild, which func_sig has already refused.

Assisted-by: Claude Code:claude-fable-5-1

* Take object and unused from CPython's Clinic signatures

CPython also falls back to these names for METH_O, but list.append and
insert, set.add, discard and remove, _weakref.getweakrefcount and
getweakrefs, sys.displayhook and getrefcount, and array.__deepcopy__
get them from an Argument Clinic signature. The earlier commit that
kept array.__deepcopy__'s `_memo` was wrong to call `unused`
synthesised.

test_pydoc's set.add summary-line tests now pass.

* host_env: gate the whole ssl module on feature ssl

* compiler: rank decode vs lexer vs print by class

Unterminated quotes no longer hide format-spec newlines or

Jeong, YunWon 66a3d9daa7 common: implement remaining builtin text codecs (#8687)
* common: implement remaining builtin text codecs

Move utf-16/32/7, unicode-escape, raw-unicode-escape and the
bytes escape transform into rustpython-common and call them from
_codecs instead of _pycodecs.

Assisted-by: Claude:grok-4.6

* host_env: share locale grouping, uuid and pipe state

Add localeconv_numeric so grouping keeps a CHAR_MAX terminator,
UuidCreateSequential for _uuid, and GetNamedPipeHandleStateW.

* Fix utf-7 clippy and the utf-16-be snippet length

Assisted-by: Claude:grok-4.6

* codecs: treat escape decode as final and accept str

unicode_escape_decode and raw_unicode_escape_decode default final to
true and accept a str as UTF-8. Fix clippy on wide_order, escape
encode, and encode closures. Remove expectedFailure markers that now
pass.

Jeong, YunWon 43ed0a80b6 Warn on invalid octal escapes and parse-fail strings (#8686)
* Warn on invalid octal escapes and parse-fail strings

Treat three-digit octal values above 0o377 as invalid escapes and
scan quoted literals even when parse fails, so SyntaxWarning is
emitted before a later SyntaxError. Keep warning and SyntaxError
text on InvalidEscape.

Enable the remaining test_string_literals invalid-escape cases.

Assisted-by: Grok:4.6

* Remove expectedFailure from passing test_codeop cases

test_invalid_warning and test_raw_raises_error now emit
SyntaxWarning on parse-fail invalid escapes.

Assisted-by: Grok:4.6

* Scan unparsed strings with token-boundary prefixes

Require a complete prefix at an identifier boundary, and walk
f-string interpolations separately after a parse failure.

Jeong, YunWon cfee8a7ffa Fix -m argv[0] and file SyntaxError display (#8684)
* Fix -m argv[0] and file SyntaxError display

Set sys.argv[0] to -m for module execution. Convert an escalated
invalid-escape SyntaxWarning into a SyntaxError that spans just
the `\X` pair. Report null bytes in source files with filename,
lineno, and the truncated line.

Enable the four corresponding test_cmd_line_script cases.

Assisted-by: Grok:4.6

* Pass SyntaxError text when escalating escape warnings

Keep the warning and SyntaxError messages as separate strings at
the invalid-escape site. CompileWarningError carries an optional
replacement instead of rewriting the warning text later.

Assisted-by: Grok:4.6

* Remove expectedFailure from bytes invalid-escape test

The invalid-escape SyntaxError path now satisfies
test_eval_bytes_invalid_escape.

Jeong, YunWon 5afe140abd Store ContextVar.name as the original str object (#8682)
* Store ContextVar.name as the original str object

Keep the constructor argument instead of converting it to a Rust String
so lone surrogates and str subclasses are preserved. Build __repr__
from the name and default reprs.

Assisted-by: Grok:4.6

* Compare Context objects by their variable maps

Implement Context ==/!= from the mapping contents and mark Context
unhashable. Snapshot the map before value equality so re-entrant
ContextVar.set during __eq__ cannot deadlock.

Enable test_context.ContextTest.test_context_run_4.

Jeong, YunWon 3fe3f37dac unicodedata: resolve name aliases and named sequences (#8676)
* unicodedata: resolve name aliases and named sequences

Vendor Unicode 17 NameAliases.txt and NamedSequences.txt into
rustpython-unicode so unicodedata.lookup matches CPython: formal
aliases and named sequences on the modern view, none on ucd_3_2_0.
Tangut derived-name lookup is case-insensitive. \N{} still rejects
named sequences because they are not a single character.

Assisted-by: Claude

* test_ucn: drop expectedFailure on test_aliases

The name-alias tables make the test pass; leaving the marker
fails CI as an unexpected success.

Assisted-by: Claude

* unicode: reject whitespace in Tangut derived names

parse_hex_code does not skip spaces around the hex digits.
