Deno tightens Node parity across core APIs

Major Node-compat work landed in timers, TLS, fs, fetch, and web cloning, plus a macOS permission fix and fs event path normalization.

TLS servers now honor client cert settings (fibibot8e15d6e)

node:tls server setup now respects requestCert, rejectUnauthorized, and ca instead of always using no-client-auth. This fixes peer certificate reporting and aligns server-side handshake behavior much more closely with Node.

structuredClone now rejects non-serializable Web types (fibibot5a14d2c)

Request, Response, Headers, and the stream classes are marked non-serializable so structuredClone(value) throws DataCloneError instead of silently round-tripping them as {}. That closes a spec/Node parity gap and prevents misleading clone results for platform objects.

fs.watchFs paths are normalized before emission (fibibotc149dd0)

Watch events now strip stray ./ and .. segments from reported paths, even when the watcher is created with a relative path like ./. This fixes noisy, confusing event output and makes file watch results more usable across platforms.

macOS permissions now compare filesystem-equivalent paths (bartlomieju35532a3)

Permission checks now normalize Unicode-equivalent and case-equivalent paths on macOS before comparing them. That brings permission decisions in line with APFS behavior, avoiding false mismatches for paths that refer to the same inode.

Byte streams are preserved for Node request bodies (fibibotff403ee)

Passing a binary stream.Readable/IncomingMessage into Request now produces a byte ReadableStream, so BYOB readers work as expected. This fixes an important interop break for proxying and other streaming HTTP code.

Node fs and timer semantics got a batch of fixes (nathanwhitbot54aa01c, nathanwhitbot318503f, bartlomiejud96c05e)

Several fs paths now validate arguments and attach richer error metadata, including path, syscall, and correct truncate/ftruncate behavior. Timers also gained Node-compatible handling around repeat state and a close() method, improving compatibility for code that relies on Node’s timer internals.

Other misc changes

  • Enabled a large batch of already-passing node_compat tests and ignored a few unsupported ones.
  • Numerous Node-compat parity fixes for crypto, process, dgram, vm, console, abort signals, URL errors, and fs watcher behavior.
  • WPT expectation updates and runner log cleanup.
  • Small docs/style and internal test tweaks.
