Functions

func Chmod added in v1.27.16

func Chmod(path string, filemode os.FileMode) error

On Windows os.Chmod only sets the read-only flag on files, so we need to use Windows APIs to set the desired access on files / directories. The OWNER mode will set file permissions for the file owner SID, the GROUP mode will set file permissions for the file group SID, and the OTHERS mode will set file permissions for BUILTIN\Users. Please note that Windows containers can be run as one of two user accounts; ContainerUser or ContainerAdministrator. Containers run as ContainerAdministrator will inherit permissions from BUILTIN\Administrators, while containers run as ContainerUser will inherit permissions from BUILTIN\Users. Windows containers do not have the ability to run as a custom user account that is known to the host so the OTHERS group mode is used to grant / deny permissions of files on the hosts to the ContainerUser account.

func MkdirAll added in v1.27.16

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

On Windows os.Mkdir all doesn't set any permissions so call the Chown function below to set permissions once the directory is created.

Types

type DefaultFs

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

DefaultFs implements Filesystem using same-named functions from "os" and "io"

func (*DefaultFs) Chtimes

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

Chtimes via os.Chtimes

func (*DefaultFs) Create

func (fs *DefaultFs) Create(name string) (File, error)

Create via os.Create

func (*DefaultFs) MkdirAll

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

func (*DefaultFs) ReadDir

func (fs *DefaultFs) ReadDir(dirname string) ([]os.DirEntry, error)

ReadDir via os.ReadDir

func (*DefaultFs) ReadFile

func (fs *DefaultFs) ReadFile(filename string) ([]byte, error)

ReadFile via os.ReadFile

func (*DefaultFs) Remove added in v1.9.0

func (fs *DefaultFs) Remove(name string) error

Remove via os.RemoveAll

func (*DefaultFs) RemoveAll

func (fs *DefaultFs) RemoveAll(path string) error

RemoveAll via os.RemoveAll

func (*DefaultFs) Rename

func (fs *DefaultFs) Rename(oldpath, newpath string) error

Rename via os.Rename

func (*DefaultFs) Stat

func (fs *DefaultFs) Stat(name string) (os.FileInfo, error)

Stat via os.Stat

func (*DefaultFs) TempDir added in v1.11.0

func (fs *DefaultFs) TempDir(dir, prefix string) (string, error)

TempDir via os.MkdirTemp

func (*DefaultFs) TempFile

func (fs *DefaultFs) TempFile(dir, prefix string) (File, error)

TempFile via os.CreateTemp

func (*DefaultFs) Walk

func (fs *DefaultFs) Walk(root string, walkFn filepath.WalkFunc) error

Walk via filepath.Walk

type FSErrorHandler

type FSErrorHandler func(err error)

FSErrorHandler is called when a fsnotify error occurs.

type FSEventHandler

type FSEventHandler func(event fsnotify.Event)

FSEventHandler is called when a fsnotify event occurs.

type FSWatcher

type FSWatcher interface {
	// Initializes the watcher with the given watch handlers.
	// Called before all other methods.
	Init(FSEventHandler, FSErrorHandler) error

	// Starts listening for events and errors.
	// When an event or error occurs, the corresponding handler is called.
	Run()

	// Add a filesystem path to watch
	AddWatch(path string) error
}

FSWatcher is a callback-based filesystem watcher abstraction for fsnotify.

func NewFsnotifyWatcher

func NewFsnotifyWatcher() FSWatcher

NewFsnotifyWatcher returns an implementation of FSWatcher that continuously listens for fsnotify events and calls the event handler as soon as an event is received.

type File

type File interface {
	// for now, the only os.File methods used are those below, add more as necessary
	Name() string
	Write(b []byte) (n int, err error)
	Sync() error
	Close() error
}

File is an interface that we can use to mock various filesystem operations typically accessed through the File object from the "os" package

type Filesystem

type Filesystem interface {
	// from "os"
	Stat(name string) (os.FileInfo, error)
	Create(name string) (File, error)
	Rename(oldpath, newpath string) error
	MkdirAll(path string, perm os.FileMode) error
	Chtimes(name string, atime time.Time, mtime time.Time) error
	RemoveAll(path string) error
	Remove(name string) error

	// from "io/ioutil"
	ReadFile(filename string) ([]byte, error)
	TempDir(dir, prefix string) (string, error)
	TempFile(dir, prefix string) (File, error)
	ReadDir(dirname string) ([]os.DirEntry, error)
	Walk(root string, walkFn filepath.WalkFunc) error
}

Filesystem is an interface that we can use to mock various filesystem operations

func NewTempFs added in v1.22.0

func NewTempFs() Filesystem

NewTempFs returns a fake Filesystem in temporary directory, useful for unit tests
