Node.js: Native Fast Paths and Filesystem Hardening
A cluster of changes push more work from JavaScript into C++ for HTTP and filesystem operations, while a separate group of fixes tightens correctness in the virtual filesystem and permission model. Together they reflect a push for both speed and safety in core I/O paths.

Good day. It's July 10th, 2026, and here's what mattered in Node dot J S today.
The clearest pattern in this batch is performance work moving into native code. Yagiz Nizipli, working under the handle anonrig, opened two related pull requests: PR 64393 adds a native single-shot response builder for HTTP, building status lines and headers in C++ instead of stitching JavaScript strings together.…
The second theme is correctness fixes in the newer virtual filesystem layer. PR 64394 fixes a race where virtual read streams could try to read a file before its descriptor was ready, causing EBADF errors during async iteration. PR 64403 closes a related gap: memory-backed file handles opened before a provider was…
Security and permissions also got attention. PR 64398 fixes permission audit mode, which is supposed to only observe and report denied access, not block it — previously it was throwing when it shouldn't have. And PR 64355, from Antoine du Hamel, cleaned up deprecated C-ares function calls in the DNS bindings,…
Finally, PR 62606 turns on OpenSSL assembly optimizations for RISC-V 64, closing a five-year-old gap now that OpenSSL 3.5 ships real RISC-V perlasm routines with runtime…
