Node.js: The Virtual File System Grows Up, and Crash Fixes Everywhere
A cluster of PRs hardened the new virtual file system to behave like a real disk, while separate fixes closed off a batch of crash and segfault paths in SQLite, QUIC, and embedder startup code. Test flakiness also got a dedicated cleanup pass covering five long-standing intermittent failures.

Good morning. It's September 6th, and today's story is about making things behave the way developers already expect them to.
The biggest thread is the virtual file system, or VFS. Pipobscure landed three related pull requests — 65814, 65852, 65853, and 65854 — all closing gaps between mounted virtual paths and real file system semantics. Watch handlers were throwing type errors instead of watching. File handles didn't respect open flags…
The second theme is crash prevention. Multiple PRs this cycle turned hard crashes into thrown errors. Lazerg's PR 65831 and TrevorBurnham's PR 65832 both target the same SQLite issue, 65830, where bad backup arguments or malformed URL-like paths could segfault or abort the process — now they throw a type error…
On the test side, Shelley Vohr's PR 65780 quietly fixed five different flaky tests in one pass — clock precision in benchmarks, a WASI thread handshake race, a watch-mode restart miscount, a DNS timeout comparison, and a core-dump timeout on SmartOS. Worth knowing if you've seen any of those fail in CI and assumed…
Also notable: panva's continued Web IDL cleanup across PRs 65844, 65845, and 65846, tightening brand checks and iterator…
