Functions

func SetupTestCerts

func SetupTestCerts(dir string) error

SetupTestCerts populates the given test 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.
