In-process Bun.cron lands with new scheduling API (
cf11b7d)
Bun now supports Bun.cron(schedule, handler) for running callbacks inside the current process, alongside the existing OS-level cron job registration and cron parsing APIs. The new handle supports stop/unref-style lifecycle control, and the docs clarify UTC vs local-time behavior across the two cron modes.
Linux statx fallback now matches libuv’s edge cases (
9053830)
fs.stat/lstat/fstat on Linux now fall back not just for ENOSYS and EOPNOTSUPP, but also for EPERM, EINVAL, and positive non-zero statx return codes. This fixes seccomp-filtered environments and other platforms where statx is unavailable in practice but didn’t previously trigger Bun’s fallback path.
Unix socket lifecycle now matches Node/libuv (
3f41407)
Bun no longer silently unlinks an existing Unix socket path before binding, which means it won’t steal a live socket from another process. It also now removes the socket file on close/finalize, fixing stale .sock file leaks and bringing behavior in line with Node.js expectations.
MacOS long Unix socket paths get a new workaround (159a285)
bun-usockets now handles macOS Unix socket paths that exceed sun_path by opening the parent directory and using __pthread_fchdir() to bind/connect via a relative basename. This mirrors Bun’s Linux path workaround and extends Unix socket support to longer paths on Apple platforms.
Event loop drains saturated ready-poll batches (ea83a74)
When epoll/kqueue fills the full ready-polls buffer, Bun now re-polls and dispatches additional events before running callbacks, up to a capped drain loop. This reduces latency and prevents large bursts of ready FDs from being processed one 1024-event slice at a time.
