Check for EINTR with != on Linux (#56) This way, ignoringEINTR becomes small enough for Go 1.16 to inline it. Co-authored-by: greatroar <@>
Extended attribute support for Go (linux + darwin + freebsd + netbsd + solaris).
“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...
SetWithFlags
allows to additionally pass system flags to be forwarded to the underlying calls. FreeBSD and NetBSD do 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 for details.
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) }
