HTTP/2 hot path gets faster and leaner (
702c553, 351da9c, 5e47f2b, 03e7945, ec8b9f4, d3b20a7)
Node’s HTTP/2 internals were heavily optimized: fewer per-write closures and scheduled callbacks, less request allocation churn, and no extra options cloning in respond(). The compat layer also got a trailer fast path that skips pointless JS/C++ round trips and empty wire work when responses have no trailers, improving throughput and reducing overhead on the common case.
WHATWG byte-stream async iteration is sped up (309213f, f91697a)
Async iteration over byte streams now avoids several reflective and buffering slow paths, making for await / reader.read() loops much closer to default streams. A matching benchmark variant was added to track the new byte-stream case.
V8 backport fixes restricted global property checks (
39d9e8c, 4ee2117)
Node backported a V8 change so restricted global-property lookups consult global interceptors when they can return non-configurable properties. Node’s vm integration and tests were updated to cover the corrected interception behavior.
QUIC stream handling avoids a no-handler crash (
2e8f4d7)
A QUIC stream could be destroyed immediately when no onstream handler existed, and the code path now checks for that case instead of crashing. The fix is covered by a new unidirectional-stream regression test.
SQLite statements now see schema changes correctly (
47e332d)
StatementSync.all() now reads the column count after stepping, which lets prepared statements reflect columns added or dropped after the statement was created. Tests now verify the same behavior for get(), all(), and iterate().
Recursive virtual mkdir follows symlinks (
d3be8ab)
The in-memory VFS now resolves symlinked intermediate directories during recursive mkdir, matching native expectations instead of throwing ENOTDIR. The update preserves the caller-visible return path and adds coverage for dangling, file, and relative-target symlink cases.
Test runner streams now report entry files (
f4c85d5)
TestStream events now include entryFile, which makes it easier to identify which test entry point produced the event. The docs and runner tests were updated to reflect the new metadata.
Other misc changes
- Removed obsolete
--napi-modulesdocs entry. - QUIC: fixed datagram stalling when no streams are pending; fixed an unobserved-closed crash.
- HTTP/2 compat/request timeout listener refactors and related cleanup.
- Updated zlib and nixpkgs.
- Added test-only fixes for spawnSync null stdio and worker stack-size determinism.
