Overview ¶

Package fsutil publishes files so that a reader, including one after a crash or power loss, sees either the previous file or the complete new one.

Index ¶

func SyncFile(path string) error
func WriteFile(path string, data []byte, mode fs.FileMode) error

Functions ¶

func SyncDir ¶

func SyncDir(directory string) error

SyncDir flushes a directory's entries, so a rename into it survives a crash. A filesystem that cannot sync a directory (EINVAL or ENOTSUP, as some network and FUSE mounts answer) offers nothing stronger, so that is not an error.

func SyncFile ¶

func SyncFile(path string) error

SyncFile flushes an already written file to disk, for a caller that publishes it with its own rename.

func WriteFile ¶

func WriteFile(path string, data []byte, mode fs.FileMode) error

WriteFile publishes data at path with the given mode through a temporary file in the same directory. The contents reach the disk before the rename, and the rename reaches it before WriteFile returns.
