Summary

Reuse the existing conversion wrappers for Python 3.15 SSL argument contracts across the OpenSSL, native rustls, WASM shim and browser backends.

Use ArgIntoBool for active boolean arguments and setters, including wrapping, certificate formats, hostname checks and supported post-handshake-auth/group options.
Use ArgIntoFloat for RAND_add entropy, including __float__, __index__ fallback and float-subclass handling.
Validate RAND_add input with ArgStrOrBytesLike even where entropy injection is a no-op.
Extract converted scalars once before state changes, retaining existing argument kinds and False defaults.
Promote browser WASM verify_mode from CERT_NONE to CERT_REQUIRED when enabling hostname checks, preserving other verification modes.

The conversion behavior follows CPython 3.15's SSL Clinic wrappers. No new parser, conversion framework, test or workflow changes are included. Existing shared binder error precedence and string-encoding behavior are outside this patch's scope.

Validation

Strict Clippy passed for rustpython-stdlib --lib --features ssl-rustls,threading.
cargo check passed for rustpython-stdlib --lib --features ssl-openssl,threading, using OpenSSL 3.5.7.
OpenSSL strict Clippy reports 41 preexisting diagnostics. The same messages and source expressions reproduce on unmodified base 94a2b2d511; no new diagnostic was found.
Formatting, diff checks and independent source review passed.
An independent 50-case CPython 3.15.0 reference probe confirmed truth/float callbacks, exception propagation, buffer-first validation and float-subclass behavior. This is reference evidence, not RustPython runtime testing.

Review follow-up (42a9891f17): cargo check --locked -p rustpython_wasm --target wasm32-unknown-unknown and focused cargo clippy --no-deps passed with warnings on unchanged code. Dependency-inclusive WASM Clippy stops at two disallowed filesystem calls in unchanged crates/vm/src/getpath.rs.

Local validation is compile/source-only. RustPython runtime, browser runtime, full-workspace and C-API tests remain unrun locally. Existing Lib/test/test_ssl.py coverage is unchanged.

AI assistance: implementation and review used OpenAI Codex; model version was not exposed.

Summary by CodeRabbit

Bug Fixes
- SSL-related options now consistently accept values convertible to booleans, including options for hostname checking, certificate output, and socket configuration.
- RAND_add now accepts string- or bytes-like input and values convertible to floating-point numbers for its entropy argument.

Sorry, something went wrong.

Walkthrough

SSL argument parsing now converts selected boolean, float, and string-or-bytes-like inputs across OpenSSL, SSL, and WebAssembly implementations. Existing setter, socket-wrapping, and certificate-query logic uses the converted values.

Changes: SSL Argument Conversions

Layer / File(s)	Summary
`RAND_add` input conversion `crates/stdlib/src/openssl.rs`, `crates/stdlib/src/ssl.rs`, `crates/stdlib/src/ssl_wasm.rs`, `crates/wasm/src/ssl.rs`	`RAND_add` parses its data as string-or-bytes-like input and its entropy as a float-convertible value. The non-OpenSSL implementation retains its no-op body.
SSL setters and socket wrapping `crates/stdlib/src/openssl.rs`, `crates/stdlib/src/ssl.rs`, `crates/stdlib/src/ssl_wasm.rs`, `crates/wasm/src/ssl.rs`	Context setters and socket or BIO wrapping convert selected arguments to `bool` before applying existing logic. The WebAssembly BIO path converts the optional `server_side` value once and defaults it to `false`.
Certificate and group query flags `crates/stdlib/src/openssl.rs`, `crates/stdlib/src/ssl.rs`, `crates/stdlib/src/ssl_wasm.rs`, `crates/wasm/src/ssl.rs`	Certificate representation flags and the OpenSSL group-alias flag use boolean conversion. Existing false defaults remain in place.

Merge Risk: Minimal · previous review 3795e

The scalar-conversion changes have no established merge-blocking regression. The browser backend still needs the reported certificate-verification correction, but that underlying defect predates this change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 14 functions across 4 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
