Use the `-short` flag to make the "stress test" run faster.
Writing new tests
-----------------
Scripts in the testdata directory allow creating test cases in a "shell-like"
syntax. The basic format is:
script
Output:
desired output
For example:
# Create a new empty file with some data.
watch /
echo data >/file
Output:
create /file
write /file
Just create a new file to add a new test; select which tests to run with
`-run TestScript/[path]`.
script
------
The script is a "shell-like" script:
cmd arg arg
Comments are supported with `#`:
# Comment
cmd arg arg # Comment
All operations are done in a temp directory; a path like "/foo" is rewritten to
"/tmp/TestFoo/foo".
Arguments can be quoted with `"` or `'`; there are no escapes and they're
functionally identical right now, but this may change in the future, so best to
assume shell-like rules.
touch "/file with spaces"
End-of-line escapes with `\` are not supported.
### Supported commands
watch path [ops] # Watch the path, reporting events for it. Nothing is
# watched by default. Optionally a list of ops can be
# given, as with AddWith(path, WithOps(...)).
unwatch path # Stop watching the path.
watchlist n # Assert watchlist length.
stop # Stop running the script; for debugging.
debug [yes/no] # Enable/disable FSNOTIFY_DEBUG (tests are run in
parallel by default, so -parallel=1 is probably a good
idea).
touch path
mkdir [-p] dir
ln -s target link # Only ln -s supported.
mkfifo path
mknod dev path
mv src dst
rm [-r] path
chmod mode path # Octal only
sleep time-in-ms
cat path # Read path (does nothing with the data; just reads it).
echo str >>path # Append "str" to "path".
echo str >path # Truncate "path" and write "str".
require reason # Skip the test if "reason" is true; "skip" and
skip reason # "require" behave identical; it supports both for
# readability. Possible reasons are:
#
# always Always skip this test.
# symlink Symlinks are supported (requires admin
# permissions on Windows).
# mkfifo Platform doesn't support FIFO named sockets.
# mknod Platform doesn't support device nodes.
output
------
After `Output:` the desired output is given; this is indented by convention, but
that's not required.
The format of that is:
# Comment
event path # Comment
system:
event path
system2:
event path
Every event is one line, and any whitespace between the event and path are
ignored. The path can optionally be surrounded in ". Anything after a "#" is
ignored.
Platform-specific tests can be added after GOOS; for example:
watch /
touch /file
Output:
# Tested if nothing else matches
create /file
# Windows-specific test.
windows:
write /file
You can specify multiple platforms with a comma (e.g. "windows, linux:").
"kqueue" is a shortcut for all kqueue systems (BSD, macOS).

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

// Reaching the limit will result in a "no space left on device" or "too many open

// # 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

import "errors"
// Watcher watches a set of paths, delivering events on a channel.
//
// A watcher should not be copied (e.g. pass it by pointer, rather than by
// value).
//
// # Linux notes
//
// When a file is removed a Remove event won't be emitted until all file
// descriptors are closed, and deletes will always emit a Chmod. For example:
//
// fp := os.Open("file")
// os.Remove("file") // Triggers Chmod
// fp.Close() // Triggers 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 the /proc file:
//
// # 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 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
// control the maximum number of open files, as well as /etc/login.conf on BSD
// systems.
//
// # Windows notes
//
// Paths can be added as "C:\path\to\dir", but forward slashes
// ("C:/path/to/dir") will also work.
//
// When a watched directory is removed it will always send an event for the
// directory itself, but may not send events for all files in that directory.
// Sometimes it will send events for all times, sometimes it will send no
// events, and often only for some files.
//
// The default ReadDirectoryChangesW() buffer size is 64K, which is the largest
// value that is guaranteed to work with SMB filesystems. If you have many
// events in quick succession this may not be enough, and you will have to use
// [WithBufferSize] to increase the value.
type Watcher struct {
// Events sends the filesystem change events.
//
// fsnotify can send the following events; a "path" here can refer to a
// file, directory, symbolic link, or special file like a FIFO.
//
// fsnotify.Create A new path was created; this may be followed by one
// or more Write events if data also gets written to a
// file.
//
// fsnotify.Remove A path was removed.
//
// fsnotify.Rename A path was renamed. A rename is always sent with the
// old path as Event.Name, and a Create event will be
// sent with the new name. Renames are only sent for
// paths that are currently watched; e.g. moving an
// unmonitored file into a monitored directory will
// show up as just a Create. Similarly, renaming a file
// to outside a monitored directory will show up as
// only a Rename.
//
// fsnotify.Write A file or named pipe was written to. A Truncate will
// also trigger a Write. A single "write action"
// initiated by the user may show up as one or multiple
// writes, depending on when the system syncs things to
// disk. For example when compiling a large Go program
// you may get hundreds of Write events, and you may
// want to wait until you've stopped receiving them
// (see the dedup example in cmd/fsnotify).
//
// Some systems may send Write event for directories
// when the directory content changes.
//
// fsnotify.Chmod Attributes were changed. On Linux this is also sent
// when a file is removed (or more accurately, when a

// when a file is truncated. On Windows it's never

//
// 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 the /proc file:
//
// # 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

// 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 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
// control the maximum number of open files, as well as /etc/login.conf on BSD
// systems.
//
// # Windows notes
//
// Paths can be added as "C:\path\to\dir", but forward slashes
// ("C:/path/to/dir") will also work.
//
// When a watched directory is removed it will always send an event for the
// directory itself, but may not send events for all files in that directory.
// Sometimes it will send events for all times, sometimes it will send no
// events, and often only for some files.
//
// The default ReadDirectoryChangesW() buffer size is 64K, which is the largest
// value that is guaranteed to work with SMB filesystems. If you have many
// events in quick succession this may not be enough, and you will have to use
// [WithBufferSize] to increase the value.

// fsnotify can send the following events; a "path" here can refer to a

// fsnotify.Create A new path was created; this may be followed by one
// or more Write events if data also gets written to a

//
// fsnotify.Remove A path was removed.
//
// fsnotify.Rename A path was renamed. A rename is always sent with the
// old path as Event.Name, and a Create event will be
// sent with the new name. Renames are only sent for
// paths that are currently watched; e.g. moving an
// unmonitored file into a monitored directory will
// show up as just a Create. Similarly, renaming a file
// to outside a monitored directory will show up as
// only a Rename.
//
// fsnotify.Write A file or named pipe was written to. A Truncate will
// also trigger a Write. A single "write action"
// initiated by the user may show up as one or multiple
// writes, depending on when the system syncs things to
// disk. For example when compiling a large Go program
// you may get hundreds of Write events, and you may
// want to wait until you've stopped receiving them
// (see the dedup example in cmd/fsnotify).
//
// Some systems may send Write event for directories
// when the directory content changes.
//
// fsnotify.Chmod Attributes were changed. On Linux this is also sent

# Simple script to update the godoc comments on all watchers so you don't need
# to update the same comment 5 times.
watcher=$(<<EOF
// Watcher watches a set of paths, delivering events on a channel.
//
// A watcher should not be copied (e.g. pass it by pointer, rather than by
// value).
//
// # Linux notes
//
// When a file is removed a Remove event won't be emitted until all file
// descriptors are closed, and deletes will always emit a Chmod. For example:
//
// fp := os.Open("file")
// os.Remove("file") // Triggers Chmod
// fp.Close() // Triggers 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 the /proc file:
//
// # 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 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
// control the maximum number of open files, as well as /etc/login.conf on BSD
// systems.
//
// # Windows notes
//
// Paths can be added as "C:\\path\\to\\dir", but forward slashes
// ("C:/path/to/dir") will also work.
//
// When a watched directory is removed it will always send an event for the
// directory itself, but may not send events for all files in that directory.
// Sometimes it will send events for all times, sometimes it will send no
// events, and often only for some files.
//
// The default ReadDirectoryChangesW() buffer size is 64K, which is the largest
// value that is guaranteed to work with SMB filesystems. If you have many
// events in quick succession this may not be enough, and you will have to use
// [WithBufferSize] to increase the value.
EOF

// NewWatcher creates a new Watcher.

newbuffered=$(<<EOF
// NewBufferedWatcher creates a new Watcher with a buffered Watcher.Events
// channel.
//
// The main use case for this is situations with a very large number of events
// where the kernel buffer size can't be increased (e.g. due to lack of
// permissions). An unbuffered Watcher will perform better for almost all use
// cases, and whenever possible you will be better off increasing the kernel
// buffers instead of adding a large userspace buffer.
EOF

add=$(<<EOF
// Add starts monitoring the path for changes.
//
// A path can only be watched once; watching it more than once is a no-op and will
// not return an error. Paths that do not yet exist on the filesystem cannot be
// watched.
//
// A watch will be automatically removed if the watched path is deleted or
// renamed. The exception is the Windows backend, which doesn't remove the
// watcher on renames.
//
// Notifications on network filesystems (NFS, SMB, FUSE, etc.) or special
// filesystems (/proc, /sys, etc.) generally don't work.
//
// Returns [ErrClosed] if [Watcher.Close] was called.
//
// See [Watcher.AddWith] for a version that allows adding options.
//
// # Watching directories
//
// All files in a directory are monitored, including new files that are created
// after the watcher is started. Subdirectories are not watched (i.e. it's
// non-recursive).
//
// # Watching files
//
// Watching individual files (rather than directories) is generally not
// recommended as many programs (especially editors) update files atomically: it
// will write to a temporary file which is then moved to to destination,
// overwriting the original (or some variant thereof). The watcher on the
// original file is now lost, as that no longer exists.
//
// The upshot of this is that a power failure or crash won't leave a
// half-written file.
//
// Watch the parent directory and use Event.Name to filter out files you're not
// interested in. There is an example of this in cmd/fsnotify/file.go.

// or more Write events if data also gets written to a
// file.
//
// fsnotify.Remove A path was removed.
//
// fsnotify.Rename A path was renamed. A rename is always sent with the
// old path as Event.Name, and a Create event will be
// sent with the new name. Renames are only sent for
// paths that are currently watched; e.g. moving an
// unmonitored file into a monitored directory will
// show up as just a Create. Similarly, renaming a file
// to outside a monitored directory will show up as
// only a Rename.
//
// fsnotify.Write A file or named pipe was written to. A Truncate will
// also trigger a Write. A single "write action"
// initiated by the user may show up as one or multiple
// writes, depending on when the system syncs things to
// disk. For example when compiling a large Go program
// you may get hundreds of Write events, and you may
// want to wait until you've stopped receiving them
// (see the dedup example in cmd/fsnotify).
//
// Some systems may send Write event for directories
// when the directory content changes.
//
// fsnotify.Chmod Attributes were changed. On Linux this is also sent
// when a file is removed (or more accurately, when a
// link to an inode is removed). On kqueue it's sent
// when a file is truncated. On Windows it's never
// sent.

## Updated Git tags
#### 13 Feb 2018
I realized that all of the git tags I had pushed before v1.7.5 were lightweight tags
and I've only recently learned that this doesn't play well with `git describe` 😞
I have replaced all lightweight tags with signed tags using this script which should
retain the commit date, name and email address. Please run `git pull --tags` to update them.
Worst case you have to reclone the repo.
```shell
#!/bin/bash
tag=$1
echo "Updating $tag"
date=$(git show ${tag}^0 --format=%aD | head -1)
email=$(git show ${tag}^0 --format=%aE | head -1)
name=$(git show ${tag}^0 --format=%aN | head -1)
GIT_COMMITTER_DATE="$date" GIT_COMMITTER_NAME="$name" GIT_COMMITTER_EMAIL="$email" git tag -s -f ${tag} ${tag}^0 -m ${tag}
```
I apologize for the inconvenience.
Frank

# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]
Simple wrappers for primitive types to enforce atomic access.
## Installation
```shell
$ go get -u go.uber.org/atomic@v1
```
### Legacy Import Path
As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
of using this package. If you are using Go modules, this package will fail to
compile with the legacy import path path `github.com/uber-go/atomic`.
We recommend migrating your code to the new import path but if you're unable
to do so, or if your dependencies are still using the old import path, you
will have to add a `replace` directive to your `go.mod` file downgrading the
legacy import path to an older version.
```
replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
```
You can do so automatically by running the following command.
```shell
$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
```
## Usage
The standard library's `sync/atomic` is powerful, but it's easy to forget which
variables must be accessed atomically. `go.uber.org/atomic` preserves all the
functionality of the standard library, but wraps the primitive types to
provide a safer, more convenient API.
```go
var atom atomic.Uint32
atom.Store(42)
atom.Sub(2)
atom.CAS(40, 11)
```
See the [documentation][doc] for a complete API specification.
## Development Status
Stable.

Releases
========
v1.11.0 (2023-03-28)
====================
- `Errors` now supports any error that implements multiple-error
interface.
- Add `Every` function to allow checking if all errors in the chain
satisfies `errors.Is` against the target error.
v1.10.0 (2023-03-08)
====================
- Comply with Go 1.20's multiple-error interface.
- Drop Go 1.18 support.
Per the support policy, only Go 1.19 and 1.20 are supported now.
- Drop all non-test external dependencies.
v1.9.0 (2022-12-12)
===================

`multierr` allows combining one or more Go `error`s together.
## Features
- **Idiomatic**:
multierr follows best practices in Go, and keeps your code idiomatic.
- It keeps the underlying error type hidden,
allowing you to deal in `error` values exclusively.
- It provides APIs to safely append into an error from a `defer` statement.
- **Performant**:
multierr is optimized for performance:
- It avoids allocations where possible.
- It utilizes slice resizing semantics to optimize common cases
like appending into the same error object from a loop.
- **Interoperable**:
multierr interoperates with the Go standard library's error APIs seamlessly:
- The `errors.Is` and `errors.As` functions *just work*.
- **Lightweight**:
multierr comes with virtually no dependencies.
## Installation
go get -u go.uber.org/multierr
```bash
go get -u go.uber.org/multierr@latest
```
