-Unreleased ----------- -Nothing yet. - -1.7.0 - 2023-10-22 ------------------- -This version of fsnotify needs Go 1.17. - -### Additions - -- 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]) - -### Changes and fixes - -- 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. - -[#371]: https://github.com/fsnotify/fsnotify/pull/371 -[#516]: https://github.com/fsnotify/fsnotify/pull/516 -[#518]: https://github.com/fsnotify/fsnotify/pull/518 -[#520]: https://github.com/fsnotify/fsnotify/pull/520 -[#521]: https://github.com/fsnotify/fsnotify/pull/521 -[#524]: https://github.com/fsnotify/fsnotify/pull/524 -[#525]: https://github.com/fsnotify/fsnotify/pull/525 -[#526]: https://github.com/fsnotify/fsnotify/pull/526 -[#528]: https://github.com/fsnotify/fsnotify/pull/528 -[#537]: https://github.com/fsnotify/fsnotify/pull/537 -[#550]: https://github.com/fsnotify/fsnotify/pull/550 -[#572]: https://github.com/fsnotify/fsnotify/pull/572 - -1.6.0 - 2022-10-13 ------------------- -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. - -[#233]: https://github.com/fsnotify/fsnotify/pull/233 -[#260]: https://github.com/fsnotify/fsnotify/pull/260 -[#288]: https://github.com/fsnotify/fsnotify/pull/288 -[#370]: https://github.com/fsnotify/fsnotify/pull/370 -[#434]: https://github.com/fsnotify/fsnotify/pull/434 -[#460]: https://github.com/fsnotify/fsnotify/pull/460 -[#463]: https://github.com/fsnotify/fsnotify/pull/463 -[#465]: https://github.com/fsnotify/fsnotify/pull/465 -[#470]: https://github.com/fsnotify/fsnotify/pull/470 -[#471]: https://github.com/fsnotify/fsnotify/pull/471 -[#475]: https://github.com/fsnotify/fsnotify/pull/475 -[#477]: https://github.com/fsnotify/fsnotify/pull/477 -[#479]: https://github.com/fsnotify/fsnotify/pull/479 -[#480]: https://github.com/fsnotify/fsnotify/pull/480 -[#485]: https://github.com/fsnotify/fsnotify/pull/485 - -## [1.5.4] - 2022-04-25 - -* Windows: add missing defer to `Watcher.WatchList` [#447](https://github.com/fsnotify/fsnotify/pull/447) -* go.mod: use latest x/sys [#444](https://github.com/fsnotify/fsnotify/pull/444) -* Fix compilation for OpenBSD [#443](https://github.com/fsnotify/fsnotify/pull/443) - -## [1.5.3] - 2022-04-22 - -* This version is retracted.
