* Support compile module context across AST warning paths
Add Python 3.15 compile(module=...) warning filtering. Move format-spec diagnostics to a fallible, literal-aware AST boundary; preserve nested literal warnings while excluding raw text and comments, map function-type fragments to source locations, and suppress duplicate type-comment emissions with per-call tracking.
Keep unrelated legacy warning-detection and exact diagnostic metadata gaps documented by differential probes. Add focused flag, source-location, exception, reentrancy, filtering and literal-boundary regression coverage.

* Reject unsupported native keywords before argument binding
Add explicit keyword dispatch metadata independently of inferred Rust
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

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

* Cover Windows time conversion error classes
Require OSError with EINVAL for representable timestamps rejected by the Windows C runtime, while preserving OverflowError for float(2**63). This initial regression-only commit intentionally exposes the current Windows error mapping before the implementation follows.
AI assistance covered source comparison, regression design, and automated Linux baseline/reference controls. Native Windows results are pending. No human validation is claimed.
Assisted-by: Codex:model-version-unavailable
* Record native Windows time conversion outcomes
The first hosted regression run failed on CPython 3.14.7 as well as RustPython because a presumed-invalid CRT timestamp succeeded. Add bounded diagnostics before the unchanged assertions to capture full version/build metadata and every conversion result, including negative half-day controls. No implementation or canonical test changes are included.
The existing time snippet still passes the repository pytest runner on Linux CPython 3.14.7 and the current RustPython baseline. Native diagnostic results remain pending.

* Use the observed UCRT rejection boundary in time regression
Hosted Windows diagnostics show that CPython 3.14.7 and RustPython both accept gmtime(-1) and gmtime(-43200), while -86400 is rejected by all three converters. Correct only the newly added shared negative test value. CPython raises OSError(errno 22) for every selected rejected value, while the RustPython baseline raises OverflowError. Canonical tests and the recorded diagnostics remain unchanged.
The existing snippet passes both Linux reference and baseline controls. Assisted source investigation and automated verification used no manual validation.

* Preserve Windows CRT time conversion errors
Return CRT errno failures from the Windows calendar helpers and translate them to Python OSError. Adapt the datetime caller while retaining its Unix behavior. Use an exclusive signed float upper bound so float(2**63) still raises OverflowError before reaching the CRT.
Keep Windows negative-time FILETIME fallback and time64 ABI changes outside this Python 3.14 extraction. Existing datetime local-error coverage is retained and a UTC error control is added for the observed rejected timestamp -86400.
Hosted native diagnostics prove CPython 3.14.7 raises OSError(errno 22) where the baseline raises OverflowError. Windows-GNU host_env check and warnings-denied Clippy pass. Selected canonical datetime and complete time/datetime snippet Linux controls pass, with six existing baseline canonical skips. Fixed native Windows verification remains pending CI.

`PyMethodDef::new_const`, `PyMethodDef::new_raw_const` and

`FromArgs::PARAMS` of each argument, exposed as `IntoPyNativeFn::ARGS`.
Flags that already contain a calling convention, such as C-API
`ml_flags`, are kept. For `METHOD` and `CLASS` the first argument is the
bound receiver. Raw functions get `FASTCALL | KEYWORDS`.
The derive macros pass only binding flags and no longer infer call flags
from Rust type names. Definitions built without the macros, such as the
`__new__` wrapper and `vm.new_function`, get calling convention flags the
same way.

round(x, ndigits) ran ndigits through __index__ before calling
__round__, so a user-defined __round__ never saw a non-integer ndigits

to float.__round__ and int.__round__.
Forward the object, and take ndigits as ArgIndex in both slots so they

* 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.

* 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.

* 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

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.

* 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

* Take bracket errors and tokenizer error priority from the parser
Bump the ruff fork, which now reports unmatched, mismatched, unclosed

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

* 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.
