Constants ¶

const SddlAdministratorsLocalSystem = "D:P(A;OICI;GA;;;BA)(A;OICI;GA;;;SY)"

SddlAdministratorsLocalSystem is local administrators plus NT AUTHORITY\System.

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 ContainerdRuntimeSupported ¶

func ContainerdRuntimeSupported() bool

ContainerdRuntimeSupported returns true if the use of containerd runtime is supported.

func EscapeArgs ¶

func EscapeArgs(args []string) string

EscapeArgs makes a Windows-style escaped command line from a set of arguments

func InitContainerdRuntime ¶

func InitContainerdRuntime(cdPath string)

InitContainerdRuntime sets whether to use containerd for runtime on Windows.

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 only supported on linux and freebsd.

func Lgetxattr ¶

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

Lgetxattr is not supported on platforms other than linux.

func Lsetxattr ¶

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

Lsetxattr is not supported on platforms other than linux.

func MkdirAll ¶

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

MkdirAll is a custom version of os.MkdirAll that is volume path aware for Windows. It can be used as a drop-in replacement for os.MkdirAll.

func MkdirAllWithACL ¶

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

MkdirAllWithACL is a custom version of os.MkdirAll modified for use on Windows so that it is both volume path aware, and can create a directory with an appropriate SDDL defined ACL.

Types ¶

type StatT ¶

type StatT struct {
	// contains filtered or unexported fields
}

StatT type contains status of a file. It contains metadata like permission, size, etc about a file.

func Lstat ¶

func Lstat(path string) (*StatT, error)

Lstat calls os.Lstat to get a fileinfo interface back. This is then copied into our own locally defined structure.

func Stat ¶

func Stat(path string) (*StatT, error)

Stat takes a path to a file and returns a system.StatT type pertaining to that file.

Throws an error if the file does not exist

func (StatT) Mode ¶

func (s StatT) Mode() os.FileMode

Mode returns file's permission mode.

func (StatT) Mtim ¶

func (s StatT) Mtim() time.Time

Mtim returns file's last modification time.

func (StatT) Size ¶

func (s StatT) Size() int64

Size returns file's size.

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
