So, `dep` got an nice new feature to remove tests and non-go files from `vendor/`, and this brings the size of the vendor directory from ~300MiB down to ~20MiB. We don that now.

xattr
|
|
=====
|
|
Extended attribute support for Go (linux + darwin + freebsd).
|
|
|
|
"Extended attributes are name:value pairs associated permanently with files and directories, similar to the environment strings associated with a process. An attribute may be defined or undefined. If it is defined, its value may be empty or non-empty." [See more...](https://en.wikipedia.org/wiki/Extended_file_attributes)
|
|
|
|
`SetWithFlags` allows to additionally pass system flags to be forwarded to the underlying calls, FreeBSD does not support this and the parameter will be ignored.
|
|
|
|
The `L` variants of all functions (`LGet/LSet/...`) are identical to `Get/Set/...` except that they
|
|
do not reference a symlink that appears at the end of a path. See
|
|
[GoDoc](http://godoc.org/github.com/pkg/xattr) for details.
|

|
|
### Example
|
|
```go
|
|
const path = "/tmp/myfile"
|
|
const prefix = "user."
|
|
|
|
if err := xattr.Set(path, prefix+"test", []byte("test-attr-value")); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
var list []string
|
|
if list, err = xattr.List(path); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
var data []byte
|
|
if data, err = xattr.Get(path, prefix+"test"); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
if err = xattr.Remove(path, prefix+"test"); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
// One can also specify the flags parameter to be passed to the OS.
|
|
if err := xattr.SetWithFlags(path, prefix+"test", []byte("test-attr-value"), xattr.XATTR_CREATE); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
```
