Functions ¶
func SyncDir ¶
syncDirAfterRename is the production post-rename step: fsync dir so the rename itself is durable. It is a no-op on Windows, where directory fsync is unsupported and rename is already journalled by NTFS.
func Write ¶
writeFileAtomic replaces path with data so that a crash or power loss leaves either the old or the new file, never a truncated one: it writes a uniquely named temp file in the same directory (concurrent writers or a stale temp from a crash cannot collide), fsyncs it and renames it over path, then best-effort fsyncs the directory via syncDirAfterRename — a failure there only warns, since the rename already committed the new file.
func WriteWithDirSync ¶
writeFileAtomicWithDirSync is writeFileAtomic with an injected post-rename dir-sync step (Store.syncDir). The injected step replaces syncDirAfterRename entirely, so tests exercise it on every platform, including Windows, without changing production Windows behaviour.
