This version of fsnotify needs Go 1.17.
illumos: add FEN backend to support illumos and Solaris. (#371)
all: add NewBufferedWatcher() to use a buffered channel, which can be useful in cases where you can't control the kernel buffer and receive a large number of events in bursts. (#550, #572)
all: add AddWith(), which is identical to Add() but allows passing options. (#521)
windows: allow setting the ReadDirectoryChangesW() buffer size with fsnotify.WithBufferSize(); the default of 64K is the highest value that works on all platforms and is enough for most purposes, but in some cases a highest buffer is needed. (#521)
inotify: remove watcher if a watched path is renamed (#518)
After a rename the reported name wasn‘t updated, or even an empty string. Inotify doesn’t provide any good facilities to update it, so just remove the watcher. This is already how it worked on kqueue and FEN.
On Windows this does work, and remains working.
windows: don't listen for file attribute changes (#520)
File attribute changes are sent as FILE_ACTION_MODIFIED by the Windows API, with no way to see if they're a file write or attribute change, so would show up as a fsnotify.Write event. This is never useful, and could result in many spurious Write events.
windows: return ErrEventOverflow if the buffer is full (#525)
Before it would merely return “short read”, making it hard to detect this error.
kqueue: make sure events for all files are delivered properly when removing a watched directory (#526)
Previously they would get sent with "" (empty string) or "." as the path name.
kqueue: don't emit spurious Create events for symbolic links (#524)
The link would get resolved but kqueue would “forget” it already saw the link itself, resulting on a Create for every Write event for the directory.
all: return ErrClosed on Add() when the watcher is closed (#516)
other: add Watcher.Errors and Watcher.Events to the no-op Watcher in backend_other.go, making it easier to use on unsupported platforms such as WASM, AIX, etc. (#528)
other: use the backend_other.go no-op if the appengine build tag is set; Google AppEngine forbids usage of the unsafe package so the inotify backend won't compile there.
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.
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.
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.
