Variables

var ErrNotSupportedPlatform = errors.New("platform and architecture is not supported")

ErrNotSupportedPlatform means the platform is not supported.

Functions

func Chtimes

func Chtimes(name string, atime time.Time, mtime time.Time) error

Chtimes changes the access time and modified time of a file at the given path. If the modified time is prior to the Unix Epoch (unixMinTime), or after the end of Unix Time (unixEpochTime), os.Chtimes has undefined behavior. In this case, Chtimes defaults to Unix Epoch, just in case.

func IsAbs

func IsAbs(path string) bool

IsAbs is a platform-agnostic wrapper for filepath.IsAbs.

On Windows, golang filepath.IsAbs does not consider a path \windows\system32 as absolute as it doesn't start with a drive-letter/colon combination. However, in docker we need to verify things such as WORKDIR /windows/system32 in a Dockerfile (which gets translated to \windows\system32 when being processed by the daemon). This SHOULD be treated as absolute from a docker processing perspective.

func LUtimesNano

func LUtimesNano(path string, ts []syscall.Timespec) error

LUtimesNano is used to change access and modification time of the specified path. It's used for symbol link file because unix.UtimesNano doesn't support a NOFOLLOW flag atm.

func Lgetxattr

func Lgetxattr(path string, attr string) ([]byte, error)

Lgetxattr retrieves the value of the extended attribute identified by attr and associated with the given path in the file system. It returns a nil slice and nil error if the xattr is not set.

func Lsetxattr

func Lsetxattr(path string, attr string, data []byte, flags int) error

Lsetxattr sets the value of the extended attribute identified by attr and associated with the given path in the file system.

func MkdirAll

func MkdirAll(path string, perm os.FileMode) error

MkdirAll creates a directory named path along with any necessary parents, with permission specified by attribute perm for all dir created.

Deprecated: os.MkdirAll now natively supports Windows GUID volume paths, and should be used instead. This alias will be removed in the next release.

func MkdirAllWithACL

func MkdirAllWithACL(path string, perm os.FileMode, _ string) error

MkdirAllWithACL is a wrapper for os.MkdirAll on unix systems.

Types

type XattrError

type XattrError struct {
	Op   string
	Attr string
	Path string
	Err  error
}

func (*XattrError) Error

func (e *XattrError) Error() string

func (*XattrError) Timeout

func (e *XattrError) Timeout() bool

Timeout reports whether this error represents a timeout.

func (*XattrError) Unwrap

func (e *XattrError) Unwrap() error
