At the head of that source file I read: * This module works by first reading the volume descriptors, then * building a list of directory entries, sorted by starting * sector. At each step, I look for the earliest dir entry that * hasn't yet been read, seek forward to that location and read * that entry. If it's a dir, I slurp in the new dir entries and * add them to the heap; if it's a regular file, I return the * corresponding archive_entry and wait for the client to request * the file body. This strategy allows us to read most compliant * CDs with a single pass through the data, as required by libarchive. This entry sequencing smells as an assumption to me. I'm not aware ECMA-119 to stipulate something like that.
