fix(stdlib): crypto.getHashes/getCiphers/getCurves/getCipherInfo through a dynamic receiver

[proggeramlug]

Part of #11046

What this fixes

crypto.getHashes() / getCiphers() / getCurves() / getCipherInfo() returned undefined whenever the receiver was not a statically known node:crypto reference. That covers a let assigned from require, a detached method value, and a module held in an object. The direct NativeModuleRef form lowers straight to the runtime helper. The dynamic form goes through js_crypto_native_dispatch (perry-stdlib), which had no arm for these four names and fell to _ => undefined.

undici 8.9.0 hits exactly this at module init in lib/web/subresource-integrity/subresource-integrity.js:

let crypto
if (runtimeFeatures.has('crypto')) {
  crypto = require('node:crypto')
  const cryptoHashes = crypto.getHashes()
  if (cryptoHashes.length === 0) {   // TypeError: Cannot read properties of undefined (reading 'length')

Under PERRY_NO_AUTO_OPTIMIZE=1 this threw on every require('undici'). Localized by instrumenting a copy of the package with per-module BEGIN/END markers and bisecting top-level statements.

Fix

Four arms in js_crypto_native_dispatch route to the existing helpers (js_crypto_get_hashes, js_crypto_get_ciphers, js_crypto_get_curves, js_crypto_get_cipher_info). There is no new behaviour, only the dynamic route to the same answers the static route already gives.

Why Part of, not Fixes

The issue's reported failure is the auto-optimize build, and there the same message comes from a different site. Function-entry instrumentation of the real package puts it in lib/dispatcher/client-h1.js Parser.execute(chunk): readMore() calls this.socket.read(), which returns undefined, and then reads chunk.length. That is #10908, and open PR #11036 addresses it. This PR does not touch it.

With this PR, the auto-optimize undici fixture still stops at that site. The no-auto build gets past subresource-integrity and hits two other gaps, now filed:

• no-auto: importing http drops RegExp.prototype.test/exec (the http-client-pump stdlib archive bundles a runtime without regex-engine) #11174: under no-auto, importing http rebuilds the pump stdlib with a runtime that lacks regex-engine, so RegExp.prototype.test/exec are undefined. undici fetch/util.js's RegExp.prototype.test.bind(...) then throws.
• Function.call !== Function.prototype.call; the Function.call.bind(fn) uncurry idiom returns undefined or throws #11175: Function.call !== Function.prototype.call, which breaks the Function.call.bind(fn) uncurry idiom. Found along the way; not confirmed as an undici blocker.

Validation (perrymaster, Linux x64, perry-dev, Node 26.5.1 at /opt/node-v26.5.1-linux-x64)

• New test-files/test_gap_11046_crypto_inventory_dynamic_receiver.cts (.cts because it uses bare require in both runtimes). It covers undici's exact let+require shape plus the SRI token filter, getCiphers/getCurves/getCipherInfo (known and unknown), detached and object-held receivers, and a static-receiver control.
  • main arm (same compiler and runtime, stdlib archive built from main's random.rs): throws Cannot read properties of undefined (reading 'length')
  • fix arm: byte-identical to Node, in both no-auto and auto-optimize builds
• Related crypto gap tests, A/B through a compile-and-diff loop (harness port 17891 was held by another job): test_gap_10427_webcrypto_method_identity, 10472_crypto_sign_verify_encoding, 10473_crypto_digest_latin1, crypto_cipher_3382_3381_2954, crypto_scrypt_options, crypto_state_2944_2945_2962, net_crypto_2549_2963, node_crypto_buffer, webcrypto_async_threadpool. All 9 pass on both arms (no-auto).
• New unit test crypto::random::tests::crypto_native_dispatch_answers_inventories passes.
• cargo test -p perry-stdlib --lib crypto (single-threaded): 23 passed, 2 failed. The two failures (native_dispatch_pbkdf2_value_form_fires_callback, native_dispatch_random_bytes_value_form_fires_callback, both timer-queue assertions) fail identically with main's random.rs, so they are not from this change.
• cargo fmt --all -- --check, scripts/check_file_size.sh, and RUSTFLAGS="-D warnings" cargo check -p perry-stdlib --all-targets are clean.
• SKIP_COMPILE_GATES=1 scripts/run_lint_gates.sh: 86 of 88 script gates pass; compile tier not run. The 2 failures are Public benchmark evidence freshness (red on main) and cargo xwin check (cargo-xwin is not installed on this host).

Not run

• Full gap sweep and the parity harness itself (port busy; covered by the targeted loop above).
• cargo test --workspace.
• macOS / Windows builds.
• Instruction-count A/B: the change adds match arms on a path that previously returned undefined, and no hot path is touched.

Summary by CodeRabbit

• Bug Fixes
  • Fixed crypto inventory methods returning undefined when called through dynamically assigned or detached crypto references. Hash, cipher, and curve listings now return their results, and cipher information lookups work as expected. This also prevents affected module imports from failing.

📝 Walkthrough

Walkthrough

The native crypto dispatcher now routes getHashes(), getCiphers(), getCurves(), and getCipherInfo() to their helpers when called through dynamic receivers. Dispatcher tests and a regression test cover inventory results and receiver forms.

Changes

Crypto inventory methods

Layer / File(s)	Summary
Inventory dispatch and unit tests crates/perry-stdlib/src/crypto/random.rs	The dispatcher routes the four methods to their helpers. Unit tests check non-empty inventory arrays, known cipher information, and undefined for an unknown cipher.
Dynamic receiver regression coverage test-files/test_gap_11046_crypto_inventory_dynamic_receiver.cts, changelog.d/11176-crypto-inventory-dynamic-dispatch.md	The regression test probes dynamic, detached, object-held, and statically assigned crypto receivers. The changelog describes the dispatch change and the undici initialization failure context.

Ready for a train. Part of #11046. Adds getHashes/getCiphers/getCurves/getCipherInfo cases to js_crypto_native_dispatch, so a dynamically held node:crypto receiver (undici's SRI module) gets arrays instead of undefined. The gap test fails on main and is byte-identical to Node with the fix, in both no-auto and auto-optimize modes. It touches perry-stdlib crypto/random.rs only.

Merge queue: this run's only non-grandfathered red, "Rekeyed side-table custody audit", was main's own break from #11169, which CI merged into this PR's test commit; #11178 fixed it. Re-running doesn't help because a re-run reuses the old merge commit. Stacked on current main together with #11162/#11173/#11176/#10946, the full run_lint_gates script tier fails only the owner-grandfathered public-baseline step, and -D warnings --all-targets on perry-stdlib/perry-runtime/perry-codegen/perry-hir plus cargo check -p perry --bins are clean. Every other CI job on this head passed.
