// against the metadata stored within the database to detect inconsistencies
|
|
// between the directory and database, such as those described in
|
|
// `design/schema.md`.
|
|
//
|
|
// As of schema version 4, the overall file format is as follows: a
|
|
// varint-encoded length, followed by a serialized `DirMeta` message, followed
|
|
// by NUL bytes padding to a total length of 512 bytes. This message never
|
|
// exceeds that length.
|
|
//
|
|
// The goal of this format is to allow atomically rewriting a meta file
|
|
// in-place. I hope that on modern OSs and hardware, a single-sector
|
|
// rewrite is atomic, though POSIX frustratingly doesn't seem to guarantee
|
|
// this. There's some discussion of that here:
|
|
// <https://stackoverflow.com/a/2068608/23584>. At worst, there's a short
|
|
// window during which the meta file can be corrupted. As the file's purpose
|
|
// is to check for inconsistencies, it can be reconstructed if you assume no
|
|
// inconsistency exists.
|
|
//
|
|
// Schema version 3 wrote a serialized DirMeta message with no length or
|
|
// padding, and renamed new meta files over the top of old. This scheme
|
|
// requires extra space while opening the directory. If the filesystem is
|
|
// completely full, it requires freeing space manually, an undocumented and
|
|
// error-prone administrator procedure.
