Node.js: QUIC Hardening and a Wave of Stream Bug Fixes
QUIC saw three connected fixes tightening session timing and stream error handling, while the streams module absorbed a cluster of edge-case corrections around cancellation, transforms, and backpressure errors. Together they point to active hardening of newer, still-maturing subsystems.

Good day. It's July 24th, and today's build shows two subsystems getting serious hardening attention: QUIC and the streams module.
Start with QUIC. Tim Perry landed PR 64132, deferring server session emit until the TLS ClientHello is actually processed — so servers don't fire session events for handshakes that were always going to fail, and can trust servername and ALPN data the moment the event lands. That groundwork exposed a real bug: PR…
Second theme: streams. Trivikram Kamat authored a run of fixes — aborting pending single-source merge reads on cancellation (64445), using RangeError instead of TypeError for broadcast overflow (64420), skipping null output from stateful transforms (64462), and preserving falsy cancellation reasons like zero or…
Worth flagging outside those themes: PR 64535 fixed a use-after-free in SQLite's Exec and ApplyChangeset when JavaScript callbacks dropped the last reference to a database mid-call — a real garbage-collection safety issue. And PR 64653 fixes a highWaterMark propagation bug that could deadlock HTTP client requests on…
What's next: expect more QUIC PRs as the stop-sending and cert-handling work continues, and watch for review on 64700's…
