Release v1.6.0
This version of fsnotify needs Go 1.16 (this was already the case since
1.5.1, but not documented). It also increases the minimum Linux version
to 2.6.32.
Additions
- all: add `Event.Has()` and `Op.Has()` ([#477])
This makes checking events a lot easier; for example:
if event.Op&Write == Write && !(event.Op&Remove == Remove) {
}
Becomes:
if event.Has(Write) && !event.Has(Remove) {
}
- all: add cmd/fsnotify ([#463])
A command-line utility for testing and some examples.
Changes and fixes
- inotify: don't ignore events for files that don't exist ([#260], [#470])
Previously the inotify watcher would call `os.Lstat()` to check if a file
still exists before emitting events.
This was inconsistent with other platforms and resulted in inconsistent event
reporting (e.g. when a file is quickly removed and re-created), and generally
a source of confusion. It was added in 2013 to fix a memory leak that no
longer exists.
- all: return `ErrNonExistentWatch` when `Remove()` is called on a path that's
not watched ([#460])
- inotify: replace epoll() with non-blocking inotify ([#434])
Non-blocking inotify was not generally available at the time this library was
written in 2014, but now it is. As a result, the minimum Linux version is
bumped from 2.6.27 to 2.6.32. This hugely simplifies the code and is faster.
- kqueue: don't check for events every 100ms ([#480])
The watcher would wake up every 100ms, even when there was nothing to do. Now
it waits until there is something to do.
- macos: retry opening files on EINTR ([#475])
- kqueue: skip unreadable files ([#479])
kqueue requires a file descriptor for every file in a directory; this would
fail if a file was unreadable by the current user. Now these files are simply
skipped.
- windows: fix renaming a watched directory if the parent is also watched ([#370])
- windows: increase buffer size from 4K to 64K ([#485])
- windows: close file handle on Remove() ([#288])
- kqueue: put pathname in the error if watching a file fails ([#471])
- inotify, windows: calling Close() more than once could race ([#465])
- kqueue: improve Close() performance ([#233])
- all: various documentation additions and clarifications.
