- Linux / Android: inotify
- macOS: FSEvents or kqueue, see features
- Windows: ReadDirectoryChangesW
- FreeBSD / NetBSD / OpenBSD / DragonflyBSD: kqueue
- All platforms: polling
Due to the inner security model of FSEvents (see FileSystemEventSecurity), some events cannot be observed easily when trying to follow files that do not belong to you. In this case, reverting to the pollwatcher can fix the issue, with a slight performance cost.
Notify was undergoing a transition to using the
Artistic License 2.0 from CC Zero 1.0. A part of
the code is only under CC0, and another part, including all new code since
3378ac5a, is under both CC0 and Artistic. When the project was to be
entirely free of CC0 code, the license would be formally changed (and that would
have incurred a major version bump). As part of this, contributions to Notify since
would agree to release under both.
Inspired by Go's fsnotify and Node.js's Chokidar, born out of need for cargo watch, and general frustration at the non-existence of C/Rust cross-platform notify libraries.
