Functions

func SetupTestCerts

func SetupTestCerts(dir string) error

SetupTestCerts populates the given test LXD directory with server certificates.

Since generating certificates is CPU intensive, they will be simply symlink'ed from the test/deps/ directory.

FIXME: this function is exported because some tests use it

directly. Eventually we should rework those tests to use NewTestOS
instead.

Types

type InotifyInfo

type InotifyInfo struct {
	Fd int
	sync.RWMutex
	Targets map[string]*InotifyTargetInfo
}

InotifyInfo records the inotify information associated with a given inotify instance

type InotifyTargetInfo

type InotifyTargetInfo struct {
	Mask uint32
	Wd   int
	Path string
}

InotifyTargetInfo records the inotify information associated with a given inotify target

type OS

type OS struct {
	VarDir   string // Data directory (e.g. /var/lib/lxd/).

OS is a high-level facade for accessing all operating-system level functionality that LXD uses.

func DefaultOS

func DefaultOS() *OS

DefaultOS returns a fresh uninitialized OS instance with default values.

func NewTestOS

func NewTestOS(t *testing.T) (*OS, func())

NewTestOS returns a new OS instance initialized with test values.

func (*OS) Init

func (s *OS) Init() error

Init our internal data structures.
