* 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.

* 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`.

* Strip a generated parameter name with unraw and one prefix check
syn already removes r# through IdentExt::unraw, the way from_args.rs

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.

* stdlib: add wasm _ssl on rustls-free host_env
Install _ssl on wasm32 against rustpython_host_env::ssl.

* Add script to run upstream pyperformance against RustPython
pyperformance can't be installed as-is on RustPython since pyperf hard-depends
on psutil, a C extension RustPython cannot build or load (no CPython C-API /
extension-module support). Since pyperf already disables psutil usage on
interpreters reporting Py_GIL_DISABLED=1 (which RustPython does, having no
GIL), a functionality-free pure-Python psutil stub is enough to satisfy pip's
dependency resolution and unblock any pure-Python benchmark.
scripts/pyperformance/run_all.py drives pyperformance (under a host CPython
venv) with RustPython as the --python target, installs the stub via
PIP_FIND_LINKS + --inherit-environ, and catalogs pass/fail/timeout per
benchmark with an automatic failure classifier (C-extension build blocked vs.
a genuine exception raised by the benchmark itself).
Assisted-by: Claude Code:claude-sonnet-5
* pyperformance: support targeting any Python and comparing catalogs
Generalize run_all.py from a RustPython-only runner to a --python/--label
pair, so the same script can catalog a real CPython (with --no-psutil-stub,
since it has a genuine psutil) alongside RustPython. Each label gets its own
results/<label>/ subdirectory.
Add compare.py, which loads two labels' catalogs and writes a per-benchmark
Markdown table with both targets' status/mean and the candidate/baseline
time ratio, plus the median slowdown across benchmarks both targets passed.
Assisted-by: Claude Code:claude-sonnet-5
* ci: compare base, head and CPython with pyperformance on one runner
A ratio between two pyperformance runs measured on different machines can
move further than the change under review did, so a PR's numbers are only
worth reading when base, head and CPython were measured back to back on the
same runner. This adds a job that does exactly that -- two release builds
kept side by side with the stdlib of their own commit, then three runs with
nothing in between -- and posts the table as a PR comment.
`pr_diff.py` renders the three catalogs `run_all.py` writes: per benchmark
the CPython time, both RustPython times, both ratios against CPython, and
the head/base change, with anything under 3% shown as `~` because a shared
runner is not quiet enough to say more.
The comment is handed to a `workflow_run` companion the same way
`codspeed-comment.yaml` does it, since a `pull_request` run from a fork gets
a read-only token however the workflow is configured.
The job is opt-in behind a `run:pyperformance` label: it runs 28 benchmarks
three times over and costs well over an hour, which most PRs do not need.
`run_all.py` now forwards RUSTPYTHONPATH through pyperf, which a binary
copied away from its checkout needs in order to find the stdlib at all; the
two names go in one comma-separated `--inherit-environ`, because repeating
the flag keeps only the last.

* ci: comment from the pyperformance run itself when the PR allows it
The `workflow_run` companion only starts firing once it is on the default
branch, so a pull request that introduces it -- this one -- would upload the
table and never show it. A pull request opened from this repo carries a
token that may write comments, so post it from the run that measured it and
leave the companion to the forks that genuinely cannot.
Both paths upsert on the same marker, so a fork PR that reaches the
companion after this step was skipped still lands one comment.

* ci: address zizmor findings and fall back to head vs. CPython
- Pin `actions/github-script` to the commit the rest of the repo pins it to;
the hash carried over from an in-flight branch pointed elsewhere than the
`v9.0.0` comment claimed (ref-version-mismatch).
- Read the PR number, the CPython path and version, and the two commit shas
from `env` rather than expanding them into the shell (template-injection).
- Record the `workflow_run` trigger in `.github/zizmor.yml` next to the
existing `pull_request_target` entry, with the same justification: the
workflow reads one artifact and writes a comment, and never checks out or
runs pull request code (dangerous-triggers).
Building or measuring the base commit is now non-fatal, and `pr_diff.py`
renders head against CPython alone when the base column has nothing in it --
a base that will not build should still leave a usable table rather than
failing the job. The time and ratio columns are also named apart, since
`| base | head | base | head |` gave no clue which pair was which.

* ci: derive pyperformance comment target from trusted workflow_run metadata
pr_number.txt came from the artifact a `pull_request` run uploads, which a
fork could tamper with to make this privileged `workflow_run` comment on an
arbitrary PR/issue. Resolve the PR from context.payload.workflow_run instead
(falling back to a commit-associated open PR lookup for workflow_dispatch
runs), and escape any HTML comments already present in diff.md so they can't
be mistaken for the marker.

* ci: grant actions:read to the pyperformance comment workflow
download-artifact needs actions:read to fetch another run's artifact by
run-id. Specifying a permissions block sets every unlisted scope to none, so
without this the cross-run download silently failed for fork PRs -- the
scenario this workflow exists for -- continue-on-error masked it, and the
comment step found no diff.md and returned without posting.

* pyperformance: kill the whole process group on a benchmark timeout
subprocess.run's own timeout only terminates the direct pyperformance
process; pyperf re-execs the target interpreter as a child, which can
survive the timeout and keep burning CPU into the next benchmark's
measurement. Run each benchmark in its own session/process group instead,
and on timeout SIGKILL the whole group via os.killpg.

* pyperformance: compute the head-vs-base cell from head_vs_base directly
The cell was derived from base_vs_cpython and head_vs_cpython, both of which
are None when a benchmark has no CPython time -- so it rendered "-" even
though base and head both had valid times and head_vs_base was already
computed. Use that precomputed ratio instead.

* pyperformance: invalidate the resumed catalog when the target executable changes
catalog.json records results without any fingerprint of target_python, and
resume skips benchmarks by name alone, so a local rebuild (or swapping the
target) under the same --label could silently reuse stale measurements.

it no longer matches, ignore the existing catalog and re-run everything.

* pyperformance: resolve --out/--cache-dir to absolute paths
Every benchmark subprocess runs with cwd=work_dir (under --cache-dir), so a
relative --out or --cache-dir passed on the command line resolved against
that directory instead of the one run_all.py was invoked from, breaking
catalog output, the pyperformance binary path, and PIP_FIND_LINKS. Both
default to absolute paths already; resolve them up front so a relative
override behaves the same way.

* pyperformance: persist catalog invalidation before the new fingerprint
The fingerprint file was rewritten before the invalidated catalog was ever
written back to disk. An interruption between the two (e.g. a crash during
the first benchmark of the re-run) left a fingerprint matching the new
executable pointing at a catalog.json still full of results measured
against the old one, so the next run would trust it as fresh. Write the
reset (empty) catalog first, then record the fingerprint.

* pyperformance: show benchmarks that fail on both base and head
Rows were dropped whenever neither side had a mean, which also hid a
benchmark that failed or timed out identically on base and head -- e.g. a
C-extension gap unrelated to the PR under review. Only skip a benchmark
never attempted on either commit; keep rows with a fail/timeout status so
they still show up in the table.

write_catalog runs after every single benchmark, and Path.write_text

mid-write left catalog.json both missing every earlier result and invalid

to a temporary sibling file and rename it into place instead.

* pyperformance: fix passed count and median population in the summary table
"Benchmarks passed" counted len(base_ratios)/len(head_ratios), which require
a *CPython* ratio too -- a CPython-only failure hid an otherwise-passing
benchmark from both sides' counts. Count actual "ok" status per side
instead.
The two medians were also computed over independently-filtered
populations: whichever benchmarks had a valid ratio on that side alone. A
benchmark that regressed to failure on only one side dropped out of only
that side's median, which could shift it well beyond what any surviving
benchmark's timing actually changed by. Restrict both medians to
benchmarks with a valid ratio on both sides, and label the population size.

* pyperformance: include RUSTPYTHONPATH's stdlib in the executable fingerprint
The catalog-invalidation fingerprint hashed only the executable's bytes, but
a RustPython binary copied away from its checkout finds its stdlib through
RUSTPYTHONPATH -- pyperf re-execs the target interpreter into a venv and
forwards that variable so it can still find Lib/. Changing that path, or
editing the files under it, without rebuilding the binary left resume
trusting results measured against a now-different stdlib. Fold its contents
into the fingerprint too.

* pyperformance: require an explicit ok/fail status for pass/fail transitions
only_head/only_base flagged a benchmark as newly passing or no longer
passing based only on whether the other side had a mean, so a benchmark
never attempted on one side (e.g. a partial --benchmarks run) was reported
as a regression or fix it never was. Require the other side's status to be
an actual fail/timeout, not just missing.

* pyperformance: don't gate the head/base geometric mean on a CPython ratio
The summary panel -- pass counts and the head/base geometric mean, neither
of which need a CPython comparison -- only rendered when at least one
benchmark also had a valid ratio against CPython on both sides. A build
with a perfectly good head-vs-base comparison but no common CPython result
lost the whole panel, including the one aggregate that didn't depend on
CPython at all.

* pyperformance: normalize RUSTPYTHONPATH and extract main() into named steps
Fix: a relative RUSTPYTHONPATH was fingerprinted relative to this script's
invocation directory but resolved by pyperf's subprocess relative to
work_dir (its cwd), so a relative value could be hashed against the wrong
directory entirely, or fail to resolve at runtime. Resolve it to an
absolute path up front, alongside --out and --cache-dir.
Refactor: main() had accumulated argparse setup, executable resolution, and
the fingerprint/resume block inline, each wrapped in an explanatory comment
-- a sign the function was doing too much rather than that it needed more
narration. Extracted parse_args(), resolve_target_python(), and
load_resumable_catalog() so main() reads as a short sequence of named
steps and each comment sits next to the one function it actually explains.
No behavior change; verified with unit tests against the extracted
functions (fingerprint reacting to RUSTPYTHONPATH, resume picking up a
prior catalog, invalidation on an executable change).

* pyperformance: split pr_diff.py's main() and fix a status-transition gap
Fix: only_head was still gated on have_base, which only asks whether *any*
base benchmark produced a timing -- so a benchmark that flipped from
failing to passing went unreported whenever every other base benchmark
also happened to fail. Status transitions don't need that gate; they
already require an explicit ok/fail/timeout status on both sides.
Refactor: main() had grown into one long function mixing argument parsing,
catalog loading, row computation, and three separate rendering concerns.
Split it into parse_args(), load_base_catalog(), build_rows(),
render_intro(), render_summary_panel(), render_table(), and
find_transitions(), each documenting the one thing it decides. No behavior
change beyond the fix above; re-verified against every scenario exercised
in the last several fixes (dual-fail rows, geo mean without a CPython
ratio, unattempted benchmarks, and the have_base gap) plus the existing
manual smoke tests.

* pyperformance: don't resolve an empty RUSTPYTHONPATH to the cwd
The normalization only checked "RUSTPYTHONPATH" in os.environ, so a set-but-
empty value (RUSTPYTHONPATH="") resolved to the current directory via
Path("").resolve(). executable_fingerprint() would then recursively hash
every file under wherever run_all.py was invoked from -- including its own
results directory while writing to it -- causing spurious catalog
invalidation and a lot of pointless hashing. Check for a nonempty value
instead, matching the truthiness check already used everywhere else this
variable is read.

* docs(pyperformance): distinguish the host runner from the benchmarked target
A reviewer read "pyperformance cannot be installed as-is on RustPython" and
reasonably asked why RustPython would need to support pyperformance's CLI at
all, since it's normally run as a command under any Python (see
https://github.com/RustPython/RustPython/pull/8691#discussion_r3997957942).
It doesn't: the pyperformance CLI (the host process) always runs under a
real CPython regardless of --python. What actually needs psutil/pyperf
importable is the *benchmark* subprocess -- pyperf re-execs the --python
target and that subprocess itself does `import pyperf`. Spell out that
host/worker split up front instead of leading with "cannot be installed".

`collect_bytes` is shared by the `bytes` and `bytearray` entry points and

"byte", so only the one caller was wrong.

`bytearray_from_object`, which carries that wording and the constructor's
unsized iteration.
