A 16-year-old SQLite race took Tailscale six months to chase down
Tailscale's uptime was wrecked for months by a rarely hit race between SQLite WAL checkpointing and write transactions, uncovered only after 19 separate corruption incidents. A masterclass in database forensics: the fix was a tiny logic check, but finding it took real archaeology. Their manual checkpointing made a 16-year-old bug far more likely to fire.
