bytearray.__mod__ copied the format and ran the arguments' __repr__,
__str__, __bytes__ and __index__ without holding an export, so a callback
could clear or extend the format and formatting went on with the old
copy:
fmt = bytearray(b"%a end")
class S:
def __repr__(self):
fmt.clear()
return "E"
fmt % S() # bytearray(b'E end'), fmt left empty
CPython holds a buffer on the format for the whole call, so the resize
fails with BufferError and the format is left as it was. Taking an export
for the duration of __mod__ does the same here, the way bytearray.join
already does for its separator.
This lets test_mod_concurrent_mutation in test_bytes run again.

object_getstate_default kept the __slotnames__ list read-locked while it
looked up each slot attribute. A getter or __getattr__ that changed the
list (as in test_descr.test_issue24097) then waited forever for the write
lock. A non-str entry in a cached __slotnames__ hit an unwrap and
panicked.
Take a reference to each name and drop the lock before the lookup, raise
TypeError for a non-str name, let errors other than AttributeError
propagate, and check the list size after each item, as CPython does.

calling flags. Reject nonempty keywords before binding and conversion,
while preserving descriptor self checks and keyword-capable calls.
Annotate 31 builtins and list.append/list.clear, derive C-API policies
from ml_flags, and group dynamic registration metadata in MethodDefSpec.
Add regression coverage and remove the id doctest expected-failure marker.
Validation: workspace and C-API tests/clippy, VM without doc, keyword
regressions, and test_call/test_extcall/test_builtin/test_list passed.
The full snippet suite had 475 passes and 7 failures: six CPython-side
expectation mismatches and one missing optional SQLite module.

* Infer native keyword dispatch from argument metadata
Replace no_keywords annotations with registration-time inference from
FromArgs::PARAMS, including nested parameter metadata. Forward arguments
with keyword-capable parameters to the binder, preserving min/max body
validation and descriptor self checks.
Add regressions for raw arguments, keyword argument structs, and list.sort.
Tested: C-API tests, workspace and C-API Clippy, VM without doc, both keyword
regression snippets, and test_call/test_extcall/test_builtin/test_list.
Workspace tests reported eight _opcode snapshot failures. The full snippet
suite reported 477 passes and seven failures: six CPython-side failures
and one RustPython failure due to the missing optional SQLite module.

* Simplify native function registration metadata
Reuse SimpleItemMeta for pyfunction attributes and remove FunctionItemMeta.
Remove MethodDefSpec and restore the original new_method_def arguments
with an additional keyword_dispatch parameter, updating its callers.
Consolidate keyword dispatch regressions in syntax_function_args.py,
preserving their assertions and placing them before builtin shadowing.
Validation: workspace and C-API tests/clippy, VM without doc, the combined
snippet, and test_extcall/test_builtin/test_list/test_call passed.
The full snippet suite reported 477 passes and seven existing failures:
six CPython-side failures and one missing optional SQLite module.

* Reject native keywords by calling convention flags
Remove `KeywordDispatch`, the `keyword_dispatch` field of `PyMethodDef`,
`PyMethodDef::with_keyword_dispatch`, `function::keyword_dispatch` and
the derive macros' `keyword_dispatch_tokens`. Native functions and method
descriptors reject nonempty keywords when `flags` lacks `KEYWORDS`, and
report the unqualified name when `flags` contains `VARARGS`.
`Context::new_method_def` takes `(name, f, flags, doc)` again. Add a
snippet for `int.__new__` called with a keyword argument.

* Reject arguments given by name and position in FuncArgs::bind_for
bind_for reports a keyword that fills a parameter already given by

#8828 made bin(), chr() and several other arguments that were bound
as PyIntRef go through __index__, but these still downcast to int and
reject an object that only defines __index__: the start and end of the
str/bytes/bytearray find family, enumerate(start=),
itertools.combinations/combinations_with_replacement/batched,
_thread.stack_size, resource.getrlimit/setrlimit, pwd.getpwuid,
grp.getgrgid, fcntl.fcntl/lockf and mmap.move/madvise. CPython converts
all of them with _PyNumber_Index or _PyEval_SliceIndex.
Bind them as ArgIndex, as #8828 did for the others.
test_mmap.test_madvise and test_mmap_closed_by_int_scenarios now pass,
so drop their expectedFailure markers.

* Match CPython's SyntaxError range for unparenthesized `except` types
CPython's `invalid_except_stmt` rule raises the error only once the whole
clause has matched, and reports a range that starts at the first exception
type and ends at the `:` closing the clause, so it covers the `as NAME`
part as well:
invalid_except_stmt:
| 'except' a=expression ',' expressions 'as' NAME ':' {
RAISE_SYNTAX_ERROR_STARTING_FROM(a, "multiple exception types
must be parenthesized when using 'as'") }
The parser reports the exception types alone, so look up that `:` in the
source and widen the range to match. Only `as NAME` may follow the
exception types, which is why the first `:` after them is the one closing
the clause.
try:
pass
except A, B, C as e:
pass
CPython 3.14: ('x.py', 3, 8, 'except A, B, C as e:\n', 3, 20)
before: ('x.py', 3, 8, 'except A, B, C as e:\n', 3, 15)
Fixes#8496

* Clarify that the `except` error range stops before the closing colon
`invalid_except_stmt_end` returns the exclusive end of the range, so the
column it yields is the one the `:` sits on even though the `:` is not part
of the range. The previous "ending at the `:`" wording read as if the colon
were included, which invites an off-by-one "fix".
Comments only; no behavior change.

* Fix the `except ... as` error column for non-ASCII names and line joins
`invalid_except_stmt_end` recovers the end of CPython's range by scanning the
source, which has to redo by hand what CPython gets from its tokenizer:
- The column was the byte distance from the line start, but `end_offset` is a
character column. `except Ä, B as e:` reported 18 instead of 17. CPython
converts explicitly, in `_PyPegen_byte_offset_to_character_offset`.
- The colon scan already spans explicit line joins, but the `as` check ran on
the raw slice, so a `\` before `as` left the range unextended.
`except A, B \` + `as exc:` reported (3, 12) instead of (4, 7).
Add regression cases to `syntax_invalid.py` covering both, plus the whitespace,
`except*` and line-join placements that already worked. All values are verified
against CPython 3.14.

* Update the Ruff fork to 0.16.10
Point the rustpython-ruff_* dependencies at the 0.16.10-rustpython tag
of the RustPython Ruff fork and port to its AST changes:
`ExprCompare` stores all operands in `operands`, call arguments use
`ThinVec`, dict comprehension generators and f-string elements are boxed
slices, `FStringValue` iterates `FStringPartRef`, and `TokenKind::Name`
is now `TokenKind::Identifier`.

* Drop the source scan for the `except ... as` error range

are removed.

* Take parse error messages from the parser as they are
The Ruff fork now emits the final message texts, so `vm_new.rs` no
longer rewrites parse error messages by matching their text and no
longer lowercases the first character of every message.
`analyze_compile_error` keeps only the caret narrowing for starred
expressions and the line number in the unterminated string message.
The compiler matches the new lowercase texts for indented block and
mixed bytes literal errors.
The fork is referenced by revision until it is published.

* Take starred and bytes literal error ranges from the parser
The Ruff fork now reports misplaced starred expressions at the `*` and
non-ASCII bytes literal errors over the whole literal. `vm_new.rs` drops
`narrow_caret` together with `SyntaxErrorInfo`, which only carried the
message after that, and the compiler drops `bytes_literal_span`.
Assisted-by: Claude Code:claude-opus-5-5
* Take indentation error kinds and positions from the parser
The Ruff fork now reports `TabError` and `TooDeepIndentation` as their
own lexer errors and places indentation and line continuation errors
itself. `vm_new.rs` picks TabError or IndentationError from the error
kind instead of scanning the source for mixed indentation, drops the
TabError message override, and sets the end offset of tokenizer errors
to 0 or -1 by kind. The compiler drops the line-end relocation of
unindent errors and the line continuation rewrite. `_tokenize` raises
TabError and depth errors for the token they replace, also for sources
containing tabs.
Remove expectedFailure from test_tokenize.test_max_indent and four
test_tabnanny tests.
Assisted-by: Claude Code:claude-opus-5-5
* Take unterminated string messages from the parser
The Ruff fork's unterminated string errors now include the detected
line and are reported at the start of the string. `vm_new.rs` drops its
message override for `UnclosedStringError`, and the shell continues a
line on an unterminated triple-quoted string by the error's
`triple_quoted` flag instead of reading the quotes from the source.

* Take bracket errors and tokenizer error priority from the parser
Bump the ruff fork, which now reports unmatched, mismatched, unclosed
and too deeply nested brackets and decides whether a tokenizer error
replaces the parser's first error.
Remove the bracket, unterminated string and nesting depth source
scanners and `pre_parse_source_error`. A tokenizer error from the
parser now wins over source scanner diagnostics found after it. An
unclosed bracket is incomplete input only when the parser reports it
as such, and other tokenizer errors end where they start.
Remove the expected failure markers from test_unicode_identifiers
test_invalid and the `import ä £` doctest in test_syntax.

Bump the ruff fork, which now reports `ExpectedIndentedBlock` with the

of `InvalidAssignmentTarget` and `InvalidNamedAssignmentTarget`.
Remove the expected failure markers from test_syntax doctests that now

variables and statements in `if` expressions. Remove the now passing
expected failure markers in test_syntax and test_named_expressions.

* Take statement errors from the parser
Bump the ruff fork to c7f6594ed6. Remove the source scanners for

`else` and mixed except handlers, and the post-parse scanners for call
arguments, match targets, yield after a comma and parenthesized star
imports.

* Take string and f-string errors from the parser
Bump the ruff fork to 6b46d0dfc8. Remove the source scanners for
malformed `\N` escapes, f-string and t-string replacement fields, mixed
t-string literals and `print`/`exec` statements, and the override
plumbing they used. Drop the `f'{x'; '` case from the compiler test,
whose expected message differs from CPython 3.14.

* Restore the bracket depth check and fix incomplete unclosed strings
Restore `pre_parse_source_error`, which rejects bracket nesting past 200
levels before parsing. The parser reports the same error but still
builds the full tree, which overflows the native stack when dropped.
Remove the VM's unclosed string scanner, which ignored the mode and
treated `'abc` in exec mode as incomplete input. The compiler's check
now skips escaped newlines.
Assisted-by: Claude Code:claude-opus-5-5
* Report multiple statements before later errors in single mode
In single mode, when the first statement is a simple statement, report
code after its line as multiple statements before any error found
later, at the newline token or the comment before it. This replaces the
multiple statements check on the parsed body and also applies to
`ast.parse(mode='single')`.
An unclosed string that follows an earlier syntax error is no longer
incomplete input. The bracket depth error range is now empty.

* Update the Ruff fork for parser speed and starred annotations
Bump the ruff fork to 8b59b85344, which skips the tokenizer error pass
when parsing finds no errors, stops allocating for every identifier's
string prefix check, and reports `def f(*args: *b = ...)` as invalid
syntax.
Remove expected failure markers from test_code_module
test_indentation_error and test_sysexcepthook_indentation_error, and
from test_dictcomps test_illegal_assignment.

* Give dict a CPython-style message for unhashable keys
Dict operations (subscription, membership, get/pop/setdefault, ...) now
raise "cannot use 'X' as a dict key (unhashable type: 'X')", matching
CPython 3.14 and mirroring the existing PySetInner wrapping. The key is
only materialized on the error path, so hashable keys pay no extra cost.
Enables Lib/test/test_dict.py::DictTest::test_unhashable_key.

* dict: only rewrite hashing failures, not key-comparison errors
wrap_unhashable_error previously rewrote any TypeError from a dict
operation as an unhashable-key error, but those operations also compare
keys on a hash collision, so a TypeError from a colliding key's __eq__
was mislabeled. Disambiguate on the error path by re-hashing the key, so
the successful path still hashes exactly once (keeps the do-not-rehash /
atomic invariants) while comparison errors propagate unchanged.
Adds a colliding-key regression test.

* dict: hash unhashable keys once up front and cover every insertion path
Addresses the review feedback (thanks @luantaraschi):
- The message now reaches update(), the constructor and |= as well, not just
__setitem__: merge_object_with_override and merge_from_seq2 now hash the key
up front and thread it into contains_known_hash/insert_known_hash.
- Hash the key once instead of re-hashing on the error path. This threads the
hash through the *_known_hash operations (add dict_inner get_known_hash), so
a __hash__ that fails only on its first call is still reported instead of
escaping unwrapped.
- Use the fully-qualified type name (matching CPython's %T).
- Only an exact TypeError is rewritten; a __hash__ raising a TypeError subclass
now propagates unchanged.
pop() and setdefault() have no *_known_hash entry point on the inner map, so
they hash once up front for the message and then do their own single lookup.
Assisted-by: Claude Opus 4.8
* dict: thread the known hash through setdefault and pop as well
Follow-up on the review: setdefault() and pop() previously hashed the key a
second time (inside the inner map) after hash_or_unhashable already hashed it,
so a stateful __hash__ failing on the second call would skip the dict-specific
message. Add setdefault_known_hash / pop_known_hash to the inner map and thread
the precomputed hash, so every operation now hashes exactly once. Adds a
regression test asserting setdefault/pop call __hash__ only once.
Assisted-by: Claude Opus 4.8
* test: hash the key on a non-empty dict so CPython 3.14 exercises the pop path
`{}.pop(CountingHash())` on an empty dict does not hash the key under
CPython 3.14 (the lookup short-circuits), so `CountingHash.calls == 1` was 0
and the snippet failed its CPython parity run. Use a non-empty dict so the
lookup must hash the key exactly once, on both CPython and RustPython. Also
applied `ruff format` (two blank lines before top-level defs).

* dict: drop unused internal pop wrapper
Per review, the vm-taking Dict::pop wrapper was dead code (#[allow(dead_code)],
kept only for API symmetry) with no callers. Remove it and fold its doc into
pop_known_hash.

* dict: rename pop_known_hash to pop
Per review, with the plain pop gone the _known_hash suffix no longer earns
its keep, so drop it. Matches the remaining known-hash helpers that still
pair with a base method.

* dict: fold setdefault wrapper into setdefault, drop unused setdefault_entry
Per review, apply the same pattern as pop: the dead setdefault wrapper only
hashed and delegated, so remove it and rename setdefault_known_hash to
setdefault (callers already thread the hash). Also drop setdefault_entry,
which this PR added but nothing uses.
