feat(node): completes basic Node API compatibility (Waves A–C)

[akapug]

This PR completes the basic Node API compatibility sweep across Elide’s GraalVM runtime, focusing on non-overlapping work with upstream PRs #1617–#1619 and aligning behavior with Node docs and tests.

Summary

• Goal: Provide broad shape/behavior parity for core Node modules used by common packages and frameworks, with conservative facades and minimal real behaviors where low-risk.
• Strategy: Avoid re-implementing upstream 1617–1619 (http Netty wiring, dns foundations, url helpers, module.createRequire loader). Implement remaining modules/polish and align semantics.
• Validation: Compiled on Windows; behavior reviewed against Node docs via Context7. Handler fallthrough semantics aligned with upstream (non-boolean returns are treated as handled).

Highlights (implemented/polished here)

• stream/promises: Implement finished() and pipeline() with robust event handling and cleanup; resolves immediately on already-ended streams; rejects on errored
• stream/consumers: text() accepts ReadableStream one-chunk inputs in addition to Buffer/Uint8Array/ArrayBuffer/string
• http/https/http2: server-like facades expose listen/close/address/on (listen invokes callback); shapes align with Node
• net: add address() for server/socket facades; isIP/isIPv4/isIPv6 via InetAddress
• module: builtinModules/isBuiltin present; createRequire loads builtins via ModuleRegistry or falls back to global require
• url: helpers implemented (domainToASCII/Unicode, fileURLToPath, pathToFileURL, urlToHttpOptions)
• dns + dns/promises: minimal resolve/resolve4/resolve6/reverse, default result order, getServers stub (aligned to upstream 1617 semantics)
• tls: minimal surface with createSecureContext/getCiphers; server/connect return server/socket-like objects
• querystring: decode/encode/escape/parse/stringify/unescape implemented
• Handler fallthrough: treat non-boolean returns as handled to avoid unexpected 404 fallthrough

Module coverage matrix (current status)

• http: Minimal facade (createServer/get/request) with listen/close/address/on; no deep Netty wiring to avoid overlap with Node next-compat: url helpers, module.createRequire, http server surface; fix handler fallthrough; targeted tests #1619
• https: Parity surface with http; server facade exposes listen/close/address/on
• http2: Facade + constants placeholder; server-like object with listen/close/address/on; minimal responsiveness
• net: createServer/connect/createConnection facades; address() included; isIP family implemented
• dns: resolve/resolve4/resolve6/reverse + set/getDefaultResultOrder + getServers stub; ENOTSUP pattern for other RR types (future work)
• dns/promises: Promise variants of resolve/4/6/reverse
• stream: present (unchanged in this PR)
• stream/consumers: behaviors for text/buffer/arrayBuffer/json/blob; text() now accepts minimal ReadableStream input
• stream/promises: finished()/pipeline() implemented with event wiring and cleanup (aligns with Node semantics)
• stream/web: present (unchanged)
• timers: setTimeout/setInterval/clear* pass-through to JS; setImmediate/clearImmediate implemented via setTimeout/clearTimeout
• timers/promises: promise wrappers for setTimeout/setImmediate with AbortSignal checks
• tls: createServer/connect stubs; createSecureContext() returns context-like object; getCiphers() via JDK SSL (fallback list)
• module: builtinModules/isBuiltin/createRequire implemented; createRequire resolves builtins and falls back to JS require
• url: domainToASCII/domainToUnicode/fileURLToPath/pathToFileURL/urlToHttpOptions implemented
• querystring: parse/stringify/escape/unescape + encode/decode present (with options handling)
• events: present (no changes in this PR)
• inspector/inspector/promises: present (no changes in this PR)
• os (+ networking bits): present (no changes in this PR)
• readline/readline/promises: present (no changes in this PR)
• worker_threads: minimal Worker/parentPort/postMessage/onmessage; terminate returns 0 (present from earlier work)
• zlib: present with rich implementation and tests (unchanged here)
• buffer/string_decoder: present (unchanged here)
• path/util/perf_hooks/process/v8/vm/wasi: present (unchanged here)
• child_process/cluster/dgram: present as placeholders/minimal stubs (no risky changes here)
• fs/fs.promises: present; not modified in this PR

Non-goals / avoided overlap

• Did not wire http#createServer to Netty engine in this PR to avoid duplicating Node next-compat: url helpers, module.createRequire, http server surface; fix handler fallthrough; targeted tests #1619; kept server-like facades for shape parity
• DNS foundations align with Node: HTTP handler semantics + DNS and DNS/Promises modules #1617 semantics; other RR types remain stubbed (future enhancement)

Build and validation notes

• Build: Gradle compile for :packages:graalvm is green on Windows
• Iteration: Behaviors validated against Node API docs via Context7; conservative and reversible changes

Follow-ups (post-merge)

• Optional: Expand stream/consumers to support AsyncIterable inputs and multi-chunk ReadableStreams
• Optional: Enhance module.createRequire to use Elide loader when a public API is available
• Optional: Add more targeted behavior tests for net/timers/consumers in CI

Thanks!

Follow-up commit pushed to branch gpt5-fun-4-windsurf with optional improvements:

• stream/consumers: text() now supports AsyncIterable inputs and multi‑chunk ReadableStreams by accumulating chunks before decode. Added behavior tests covering both cases.
• module.createRequire: left as builtins + global require fallback for now. There is an internal ElideUniversalJsModuleLoader that could be used when a stable public API becomes available; I will wire it once it’s exposed (or if guidance allows using the internal API safely).
• CI tests: Added targeted behavior tests for stream/consumers; net/timers already have decent shape tests in this repo. If you want, I can add more targeted timers/net behavior tests in a follow-up.

Build remains green locally. Let me know if you prefer shifting createRequire to Elide’s loader via a sanctioned public API in this PR, and I’ll update accordingly.

Patch pushed to fix CI compile errors identified by the build:

• NodePunycodeTest: now implements injectable pattern and requiredMembers. Adds @Inject field and testInjectable override.
• NodeV8Test: removed use of the DSL test {}; simple JUnit @Test now calls require(). Note: Elide runs GraalJS not V8; test only verifies facade shape.
• NodeWasiSmokeTest: switched to executeGuest { code } form to satisfy signature; the test still asserts WASI constructor is present.
• NodeStreamConsumersBehaviorTest: uses polyglotContext.javascript(js) directly so the function signature is clear to K/JVM; also updated imports to use the JS plugin helper where needed.

Locally recompiled tests; KSP-on-Windows still emits the known root mismatch warning, but in CI (Linux) the earlier failure was due to test sources. Please re-run CI; I’m standing by to address any further issues that arise in Linux CI specifically.
