func FtimeGranularity ¶

func FtimeGranularity() time.Duration

FtimeGranularity is the filesystem timestamp granularity for this system. TODO: We should probably make this dependent on the path since some

filesystems can have different granularities...

func IsTestBinary ¶

func IsTestBinary() bool

IsTestBinary returns whether the current binary is a test binary. This is only ever meant to be used so that test-specific initialisations can be done inside packages. Don't use it for anything else.

func MakeReadOnly ¶

func MakeReadOnly(t *testing.T, path string)

MakeReadOnly makes the given path read-only (by bind-mounting it as "ro"). TODO: This should be done through an interface restriction in the test

(which is then backed up by the readonly mount if necessary). The fact
this test is necessary is a sign that we need a better split up of the
CAS interface.

func MakeReadWrite ¶

func MakeReadWrite(t *testing.T, path string)

MakeReadWrite undos the effect of MakeReadOnly.

func RandomString ¶

func RandomString(n int) string

RandomString returns a pseudorandom alphabetical (mixed-case) string.

func Unix ¶

func Unix(sec, nsec int64) time.Time

Unix returns the local Time corresponding to the given Unix time, rounded to the timestamp granularity for this system.
