// Package log provides types and functions related to logging, passing

//
|
||||
// # Transitional types
|
||||
//
|
||||
// This package contains various types that are aliases for types in [logrus].
|
||||
// These aliases are intended for transitioning away from hard-coding logrus
|
||||
// as logging implementation. Consumers of this package are encouraged to use
|
||||
// the type-aliases from this package instead of directly using their logrus
|
||||
// equivalent.
|
||||
//
|
||||
// The intent is to replace these aliases with locally defined types and
|
||||
// interfaces once all consumers are no longer directly importing logrus
|
||||
// types.
|
||||
//
|
||||
// IMPORTANT: due to the transitional purpose of this package, it is not
|
||||
// guaranteed for the full logrus API to be provided in the future. As
|
||||
// outlined, these aliases are provided as a step to transition away from
|
||||
// a specific implementation which, as a result, exposes the full logrus API.
|
||||
// While no decisions have been made on the ultimate design and interface
|
||||
// provided by this package, we do not expect carrying "less common" features.

# Changelog
|
||||
|
||||
All notable changes to this project will be documented in this file.
|
||||
|
||||
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
||||
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
## [Unreleased]
|
||||
|
||||
Nothing yet.
|
||||
|
||||
## [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.

Thank you for your interest in contributing to fsnotify! We try to review and
|
||||
merge PRs in a reasonable timeframe, but please be aware that:
|
||||
|
||||
- To avoid "wasted" work, please discus changes on the issue tracker first. You
|
||||
can just send PRs, but they may end up being rejected for one reason or the
|
||||
other.
|
||||
|
||||
- fsnotify is a cross-platform library, and changes must work reasonably well on
|
||||
all supported platforms.
|
||||
|
||||
- Changes will need to be compatible; old code should still compile, and the
|
||||
runtime behaviour can't change in ways that are likely to lead to problems for
|
||||
users.
|
||||
|
||||
Testing
|
||||
-------
|
||||
Just `go test ./...` runs all the tests; the CI runs this on all supported
|
||||
platforms. Testing different platforms locally can be done with something like
|
||||
[goon] or [Vagrant], but this isn't super-easy to set up at the moment.
|
||||
|
||||
Use the `-short` flag to make the "stress test" run faster.

fsnotify is a Go library to provide cross-platform filesystem notifications on
|
||||
Windows, Linux, macOS, and BSD systems.
|
||||
|
||||
Go 1.16 or newer is required; the full documentation is at
|
||||
https://pkg.go.dev/github.com/fsnotify/fsnotify
|
||||
|
||||
**It's best to read the documentation at pkg.go.dev, as it's pinned to the last
|
||||
released version, whereas this README is for the last development version which
|
||||
may include additions/changes.**

Usage
|
||||
-----
|
||||
A basic example:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/fsnotify/fsnotify"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create new watcher.
|
||||
watcher, err := fsnotify.NewWatcher()
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
defer watcher.Close()
|
||||
|
||||
// Start listening for events.
|
||||
go func() {
|
||||
for {
|
||||
select {
|
||||
case event, ok := <-watcher.Events:
|
||||
if !ok {
|
||||
return
|
||||
}
|
||||
log.Println("event:", event)
|
||||
if event.Has(fsnotify.Write) {
|
||||
log.Println("modified file:", event.Name)
|
||||
}
|
||||
case err, ok := <-watcher.Errors:
|
||||
if !ok {
|
||||
return
|
||||
}
|
||||
log.Println("error:", err)
|
||||
}
|
||||
}
|
||||
}()
|
||||
|
||||
// Add a path.
|
||||
err = watcher.Add("/tmp")
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
// Block main goroutine forever.
|
||||
<-make(chan struct{})
|
||||
}
|
||||
```
|
||||
|
||||
Some more examples can be found in [cmd/fsnotify](cmd/fsnotify), which can be
|
||||
run with:
|
||||
|
||||
% go run ./cmd/fsnotify

||||
|
||||
FAQ
|
||||
---
|
||||
### Will a file still be watched when it's moved to another directory?
|
||||
No, not unless you are watching the location it was moved to.
|
||||
|
||||
### Are subdirectories watched too?
|
||||
No, you must add watches for any directory you want to watch (a recursive
|
||||
watcher is on the roadmap: [#18]).
|
||||
|
||||
[#18]: https://github.com/fsnotify/fsnotify/issues/18
|
||||
|
||||
### Do I have to watch the Error and Event channels in a goroutine?
|
||||
As of now, yes (you can read both channels in the same goroutine using `select`,
|
||||
you don't need a separate goroutine for both channels; see the example).
|
||||
|
||||
### Why don't notifications work with NFS, SMB, FUSE, /proc, or /sys?
|
||||
fsnotify requires support from underlying OS to work. The current NFS and SMB
|
||||
protocols does not provide network level support for file notifications, and
|
||||
neither do the /proc and /sys virtual filesystems.
|
||||
|
||||
This could be fixed with a polling watcher ([#9]), but it's not yet implemented.
|
||||
|
||||
[#9]: https://github.com/fsnotify/fsnotify/issues/9
|
||||
|
||||
Platform-specific notes
|
||||
-----------------------
|
||||
### Linux
|
||||
When a file is removed a REMOVE event won't be emitted until all file
|
||||
descriptors are closed; it will emit a CHMOD instead:
|
||||
|
||||
fp := os.Open("file")
|
||||
os.Remove("file") // CHMOD
|
||||
fp.Close() // REMOVE
|
||||
|
||||
This is the event that inotify sends, so not much can be changed about this.
|
||||
|
||||
The `fs.inotify.max_user_watches` sysctl variable specifies the upper limit for
|
||||
the number of watches per user, and `fs.inotify.max_user_instances` specifies
|
||||
the maximum number of inotify instances per user. Every Watcher you create is an
|
||||
"instance", and every path you add is a "watch".
|
||||
|
||||
These are also exposed in `/proc` as `/proc/sys/fs/inotify/max_user_watches` and
|
||||
`/proc/sys/fs/inotify/max_user_instances`
|
||||
|
||||
To increase them you can use `sysctl` or write the value to proc file:
|
||||
|
||||
# The default values on Linux 5.18
|
||||
sysctl fs.inotify.max_user_watches=124983
|
||||
sysctl fs.inotify.max_user_instances=128
|
||||
|
||||
To make the changes persist on reboot edit `/etc/sysctl.conf` or
|
||||
`/usr/lib/sysctl.d/50-default.conf` (details differ per Linux distro; check your
|
||||
distro's documentation):
|
||||
|
||||
fs.inotify.max_user_watches=124983
|
||||
fs.inotify.max_user_instances=128
|
||||
|
||||
Reaching the limit will result in a "no space left on device" or "too many open
|
||||
files" error.
|
||||
|
||||
### kqueue (macOS, all BSD systems)
|
||||
kqueue requires opening a file descriptor for every file that's being watched;
|
||||
so if you're watching a directory with five files then that's six file
|
||||
descriptors. You will run in to your system's "max open files" limit faster on
|
||||
these platforms.
|
||||
|
||||
The sysctl variables `kern.maxfiles` and `kern.maxfilesperproc` can be used to
|
||||
control the maximum number of open files.
|
||||
|
||||
### macOS
|
||||
Spotlight indexing on macOS can result in multiple events (see [#15]). A temporary
|
||||
workaround is to add your folder(s) to the *Spotlight Privacy settings* until we
|
||||
have a native FSEvents implementation (see [#11]).

// # kqueue notes (macOS, BSD)

// create is an "instance", and every path you add is a "watch".

// These are also exposed in /proc as /proc/sys/fs/inotify/max_user_watches and
|
||||
// /proc/sys/fs/inotify/max_user_instances
|

//
|

// # Default values on Linux 5.18
|

// sysctl fs.inotify.max_user_watches=124983
|

// sysctl fs.inotify.max_user_instances=128
|

//
|

// To make the changes persist on reboot edit /etc/sysctl.conf or
|

// /usr/lib/sysctl.d/50-default.conf (details differ per Linux distro; check

// your distro's documentation):
|

// fs.inotify.max_user_watches=124983
|

// fs.inotify.max_user_instances=128
|

|
||||
// files" error.
|

//
|
||||
// # kqueue notes (macOS, BSD)
|
||||
//
|
||||
// kqueue requires opening a file descriptor for every file that's being watched;

// so if you're watching a directory with five files then that's six file

// descriptors. You will run in to your system's "max open files" limit faster on
|

// these platforms.
|

// The sysctl variables kern.maxfiles and kern.maxfilesperproc can be used to

// systems.
