func RemoveTmpDirs ¶ added in v0.311.0

func RemoveTmpDirs(l *slog.Logger, dir string, isTmpDir func(fi fs.DirEntry) bool) error

RemoveTmpDirs attempts to remove directories in the specified directory which match the isTmpDir predicate. Errors encountered during reading the directory that other than non-existence are returned. All other errors encountered during removal of tmp directories are logged but do not cause early termination.

func TestDirLockerUsage ¶

func TestDirLockerUsage(t *testing.T, open func(t *testing.T, data string, createLock bool) (*DirLocker, testutil.Closer))

TestDirLockerUsage performs a set of tests which guarantee correct usage of DirLocker. open should use data as the storage directory, and createLock to determine if a lock file should be used.
