# Changelog
1.8.0 2023-10-31
----------------
### Additions
- all: add `FSNOTIFY_DEBUG` to print debug logs to stderr ([#619])

- windows: fix behaviour of `WatchList()` to be consistent with other platforms ([#610])
- kqueue: ignore events with Ident=0 ([#590])
- kqueue: set O_CLOEXEC to prevent passing file descriptors to children ([#617])
- kqueue: emit events as "/path/dir/file" instead of "path/link/file" when watching a symlink ([#625])
- inotify: don't send event for IN_DELETE_SELF when also watching the parent ([#620])

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.

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 discuss 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.
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).

fsnotify is a Go library to provide cross-platform filesystem notifications on
Windows, Linux, macOS, BSD, and illumos.
Go 1.17 or newer is required; the full documentation is at
https://pkg.go.dev/github.com/fsnotify/fsnotify
---
Platform support:
| Backend | OS | Status |
| :-------------------- | :--------- | :------------------------------------------------------------------------ |
| inotify | Linux | Supported |
| kqueue | BSD, macOS | Supported |
| ReadDirectoryChangesW | Windows | Supported |
| FEN | illumos | Supported |
| fanotify | Linux 5.9+ | [Not yet](https://github.com/fsnotify/fsnotify/issues/114) |
| AHAFS | AIX | [aix branch]; experimental due to lack of maintainer and test environment |
| FSEvents | macOS | [Needs support in x/sys/unix][fsevents] |
| USN Journals | Windows | [Needs support in x/sys/windows][usn] |
| Polling | *All* | [Not yet](https://github.com/fsnotify/fsnotify/issues/9) |
Linux and illumos should include Android and Solaris, but these are currently
untested.

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?
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?
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
### Why do I get many Chmod events?
Some programs may generate a lot of attribute changes; for example Spotlight on
macOS, anti-virus programs, backup applications, and some others are known to do
this. As a rule, it's typically best to ignore Chmod events. They're often not
useful, and tend to cause problems.
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]).
[#11]: https://github.com/fsnotify/fsnotify/issues/11
[#15]: https://github.com/fsnotify/fsnotify/issues/15
### Watching a file doesn't work well
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`.
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.

// Package fsnotify provides a cross-platform interface for file system

//
// Currently supported systems:
//
// - Linux via inotify
// - BSD, macOS via kqueue
// - Windows via ReadDirectoryChangesW
// - illumos via FEN
//
// # FSNOTIFY_DEBUG
//
// Set the FSNOTIFY_DEBUG environment variable to "1" to print debug messages to
// stderr. This can be useful to track down some problems, especially in cases
// where fsnotify is used as an indirect dependency.
//
// Every event will be printed as soon as there's something useful to print,
// with as little processing from fsnotify.
//
// Example output:
//
// FSNOTIFY_DEBUG: 11:34:23.633087586 256:IN_CREATE → "/tmp/file-1"
// FSNOTIFY_DEBUG: 11:34:23.633202319 4:IN_ATTRIB → "/tmp/file-1"

// 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 files, 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.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
// link to an inode is removed). On kqueue it's sent

# concurrent map [![Build Status](https://travis-ci.com/orcaman/concurrent-map.svg?branch=master)](https://travis-ci.com/orcaman/concurrent-map)
正如 [这里](http://golang.org/doc/faq#atomic_maps) 和 [这里](http://blog.golang.org/go-maps-in-action)所描述的, Go语言原生的`map`类型并不支持并发读写。`concurrent-map`提供了一种高性能的解决方案:通过对内部`map`进行分片，降低锁粒度，从而达到最少的锁等待时间(锁冲突)
在Go 1.9之前，go语言标准库中并没有实现并发`map`。在Go 1.9中，引入了`sync.Map`。新的`sync.Map`与此`concurrent-map`有几个关键区别。标准库中的`sync.Map`是专为`append-only`场景设计的。因此，如果您想将`Map`用于一个类似内存数据库，那么使用我们的版本可能会受益。你可以在golang repo上读到更多，[这里](https://github.com/golang/go/issues/21035) and [这里](https://stackoverflow.com/questions/11063473/map-with-concurrent-access)
***译注:`sync.Map`在读多写少性能比较好，否则并发性能很差***
## 用法
导入包:
```go
import (
"github.com/orcaman/concurrent-map/v2"
)
```
```bash
go get "github.com/orcaman/concurrent-map/v2"
```
现在包被导入到了`cmap`命名空间下
***译注:通常包的限定前缀(命名空间)是和目录名一致的，但是这个包有点典型😂，不一致！！！所以用的时候注意***
## 示例
```go
// 创建一个新的 map.
m := cmap.New[string]()
// 设置变量m一个键为“foo”值为“bar”键值对
m.Set("foo", "bar")
// 从m中获取指定键值.
bar, ok := m.Get("foo")
// 删除键为“foo”的项
m.Remove("foo")
```
更多使用示例请查看`concurrent_map_test.go`.
运行测试:
```bash
go test "github.com/orcaman/concurrent-map/v2"
```
## 贡献说明
我们非常欢迎大家的贡献。如欲合并贡献，请遵循以下指引:
- 新建一个issue,并且叙述为什么这么做(解决一个bug，增加一个功能，等等)
- 根据核心团队对上述问题的反馈，提交一个PR，描述变更并链接到该问题。
- 新代码必须具有测试覆盖率。
- 如果代码是关于性能问题的，则必须在流程中包括基准测试(无论是在问题中还是在PR中)。
- 一般来说，我们希望`concurrent-map`尽可能简单，且与原生的`map`有相似的操作。当你新建issue时请注意这一点。

# concurrent map [![Build Status](https://travis-ci.com/orcaman/concurrent-map.svg?branch=master)](https://travis-ci.com/orcaman/concurrent-map)
As explained [here](http://golang.org/doc/faq#atomic_maps) and [here](http://blog.golang.org/go-maps-in-action), the `map` type in Go doesn't support concurrent reads and writes. `concurrent-map` provides a high-performance solution to this by sharding the map with minimal time spent waiting for locks.
Prior to Go 1.9, there was no concurrent map implementation in the stdlib. In Go 1.9, `sync.Map` was introduced. The new `sync.Map` has a few key differences from this map. The stdlib `sync.Map` is designed for append-only scenarios. So if you want to use the map for something more like in-memory db, you might benefit from using our version. You can read more about it in the golang repo, for example [here](https://github.com/golang/go/issues/21035) and [here](https://stackoverflow.com/questions/11063473/map-with-concurrent-access)
## usage
Import the package:
```go
import (
"github.com/orcaman/concurrent-map/v2"
)
```
```bash
go get "github.com/orcaman/concurrent-map/v2"
```
The package is now imported under the "cmap" namespace.
## example
```go
// Create a new map.
m := cmap.New[string]()
// Sets item within map, sets "bar" under key "foo"
m.Set("foo", "bar")
// Retrieve item from map.
bar, ok := m.Get("foo")
// Removes item under key "foo"
m.Remove("foo")
```
For more examples have a look at concurrent_map_test.go.
Running tests:
```bash
go test "github.com/orcaman/concurrent-map/v2"
```
## guidelines for contributing
Contributions are highly welcome. In order for a contribution to be merged, please follow these guidelines:
- Open an issue and describe what you are after (fixing a bug, adding an enhancement, etc.).
- According to the core team's feedback on the above mentioned issue, submit a pull request, describing the changes and linking to the issue.
- New code must have test coverage.
- If the code is about performance issues, you must include benchmarks in the process (either in the issue or in the PR).
- In general, we would like to keep `concurrent-map` as simple as possible and as similar to the native `map`. Please keep this in mind when opening issues.

# Building `sys/unix`
The sys/unix package provides access to the raw system call interface of the
underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
Porting Go to a new architecture/OS combination or adding syscalls, types, or
constants to an existing architecture/OS pair requires some manual effort;
however, there are tools that automate much of the process.
## Build Systems
There are currently two ways we generate the necessary files. We are currently
migrating the build system to use containers so the builds are reproducible.
This is being done on an OS-by-OS basis. Please update this documentation as
components of the build system change.
### Old Build System (currently for `GOOS != "linux"`)
The old build system generates the Go files based on the C header files
present on your system. This means that files
for a given GOOS/GOARCH pair must be generated on a system with that OS and
architecture. This also means that the generated code can differ from system
to system, based on differences in the header files.
To avoid this, if you are using the old build system, only generate the Go
files on an installation with unmodified header files. It is also important to
keep track of which version of the OS the files were generated from (ex.
Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
and have each OS upgrade correspond to a single change.
To build the files for your current OS and architecture, make sure GOOS and
GOARCH are set correctly and run `mkall.sh`. This will generate the files for
your specific system. Running `mkall.sh -n` shows the commands that will be run.
Requirements: bash, go
### New Build System (currently for `GOOS == "linux"`)
The new build system uses a Docker container to generate the go files directly
from source checkouts of the kernel and various system libraries. This means
that on any platform that supports Docker, all the files using the new build
system can be generated at once, and generated files will not change based on
what the person running the scripts has installed on their computer.
The OS specific files for the new build system are located in the `${GOOS}`
directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
the kernel or system library updates, modify the Dockerfile at
`${GOOS}/Dockerfile` to checkout the new release of the source.
To build all the files under the new build system, you must be on an amd64/Linux
system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
then generate all of the files for all of the GOOS/GOARCH pairs in the new build
system. Running `mkall.sh -n` shows the commands that will be run.
Requirements: bash, go, docker
## Component files
This section describes the various files used in the code generation process.
It also contains instructions on how to modify these files to add a new
architecture/OS or to add additional syscalls, types, or constants. Note that
if you are using the new build system, the scripts/programs cannot be called normally.
They must be called from within the docker container.
### asm files
The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
call dispatch. There are three entry points:
```
func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
```
The first and second are the standard ones; they differ only in how many
arguments can be passed to the kernel. The third is for low-level use by the
ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
let it know that a system call is running.
When porting Go to a new architecture/OS, this file must be implemented for
each GOOS/GOARCH pair.
### mksysnum
Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
for the old system). This program takes in a list of header files containing the
syscall number declarations and parses them to produce the corresponding list of
Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
constants.
Adding new syscall numbers is mostly done by running the build on a sufficiently
new installation of the target OS (or updating the source checkouts for the
new build system). However, depending on the OS, you may need to update the
parsing in mksysnum.
### mksyscall.go
The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
hand-written Go files which implement system calls (for unix, the specific OS,
or the specific OS/Architecture pair respectively) that need special handling
and list `//sys` comments giving prototypes for ones that can be generated.
The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
them into syscalls. This requires the name of the prototype in the comment to
match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
prototype can be exported (capitalized) or not.
Adding a new syscall often just requires adding a new `//sys` function prototype
with the desired arguments and a capitalized name so it is exported. However, if
you want the interface to the syscall to be different, often one will make an
unexported `//sys` prototype, and then write a custom wrapper in
`syscall_${GOOS}.go`.
### types files
For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
`types_${GOOS}.go` on the old system). This file includes standard C headers and
creates Go type aliases to the corresponding C types. The file is then fed
through godef to get the Go compatible definitions. Finally, the generated code
is fed though mkpost.go to format the code correctly and remove any hidden or
private identifiers. This cleaned-up code is written to
`ztypes_${GOOS}_${GOARCH}.go`.
The hardest part about preparing this file is figuring out which headers to
include and which symbols need to be `#define`d to get the actual data
structures that pass through to the kernel system calls. Some C libraries
preset alternate versions for binary compatibility and translate them on the
way in and out of system calls, but there is almost always a `#define` that can
get the real ones.
See `types_darwin.go` and `linux/types.go` for examples.
To add a new type, add in the necessary include statement at the top of the
file (if it is not already there) and add in a type alias line. Note that if
your type is significantly different on different architectures, you may need
some `#if/#elif` macros in your include statements.
### mkerrors.sh
This script is used to generate the system's various constants. This doesn't
just include the error numbers and error strings, but also the signal numbers
and a wide variety of miscellaneous constants. The constants come from the list
of include files in the `includes_${uname}` variable. A regex then picks out
the desired `#define` statements, and generates the corresponding Go constants.
The error numbers and strings are generated from `#include <errno.h>`, and the
signal numbers and strings are generated from `#include <signal.h>`. All of
these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
`_errors.c`, which prints out all the constants.
To add a constant, add the header that includes it to the appropriate variable.
Then, edit the regex (if necessary) to match the desired constant. Avoid making
the regex too broad to avoid matching unintended constants.
### internal/mkmerge
This program is used to extract duplicate const, func, and type declarations
from the generated architecture-specific files listed below, and merge these
into a common file for each OS.
The merge is performed in the following steps:
1. Construct the set of common code that is idential in all architecture-specific files.
2. Write this common code to the merged file.
3. Remove the common code from all architecture-specific files.
## Generated files
### `zerrors_${GOOS}_${GOARCH}.go`
A file containing all of the system's generated error numbers, error strings,
signal numbers, and constants. Generated by `mkerrors.sh` (see above).
### `zsyscall_${GOOS}_${GOARCH}.go`
A file containing all the generated syscalls for a specific GOOS and GOARCH.
Generated by `mksyscall.go` (see above).
### `zsysnum_${GOOS}_${GOARCH}.go`
A list of numeric constants for all the syscall number of the specific GOOS
and GOARCH. Generated by mksysnum (see above).
### `ztypes_${GOOS}_${GOARCH}.go`
A file containing Go types for passing into (or returning from) syscalls.
Generated by godefs and the types file (see above).
