Node.js: Hardening Native Boundaries and Cutting File System Overhead
A cluster of fixes closed off ways JavaScript input could crash the process with a hard abort, while two separate performance efforts cut redundant native round-trips in file system reads and web stream encoding.

Good morning. It's August 25th, and today's codebase activity centers on one theme: turning process-crashing aborts into recoverable JavaScript errors, plus a solid push on file system performance.
Start with reliability. Several PRs closed gaps where bad input from JavaScript could hit a C++ check and bring down the whole process. Sankalp Thakur's PR 65076 fixes TLS connections that abort with SIGABRT when ALPN protocols are malformed — now they throw a normal, catchable error. Rafael Gonzaga's PR 65430 stops…
Second theme: file system performance. Two competing PRs — Shelley Vohr's 65487, which merged, and Aviv Keller's still-open 65524 — both tackle the same waste in recursive directory reading: stopping a stat call on every single entry and cutting the number of trips between JavaScript and native code. Vohr's version,…
On the streaming side, Matteo Collina's PR 65414 rewrites TextEncoderStream to encode whole chunks natively instead of character by character, with reported gains up to five times faster on large chunks. Trivikram Kamat's PR 65367 fixes a correctness issue where fused stream transforms could return inconsistent…
Also worth noting: pimterry's PR 65522 generalizes…
