Functions

func AtomicRemoveFile

func AtomicRemoveFile(path string) error

AtomicRemoveFile removes a file and syncs its parent directory.

func AtomicWrite

func AtomicWrite(path string, content []byte) error

AtomicWrite writes content with the default AGH file permissions via temp-file-and-rename.

func AtomicWriteFile

func AtomicWriteFile(path string, content []byte, perm os.FileMode) error

AtomicWriteFile writes content to path via a temp file plus atomic replacement. It always syncs the temp file before replacement. Parent-directory metadata durability remains best-effort on platforms without directory fsync support.

func SyncDir

func SyncDir(path string) error

SyncDir fsyncs directory metadata when the current platform supports it.
