 * entries properly even if the hosting platform can't store them on
 * disk.
 *
 * These values are also used directly within some portable formats,

/*
 * Utility to match up hardlinks.
 *
 * The 'struct archive_entry_linkresolver' is a cache of archive entries
 * for files with multiple links.  Here's how to use it:
 *   1. Create a lookup object with archive_entry_linkresolver_new()
 *   2. Tell it the archive format you're using.
 *   3. Hand each archive_entry to archive_entry_linkify().
 *      That function will return 0, 1, or 2 entries that should
 *      be written.
 *   4. Call archive_entry_linkify(resolver, NULL) until
 *      no more entries are returned.
 *   5. Call archive_entry_linkresolver_free(resolver) to free resources.
 *
 * The entries returned have their hardlink and size fields updated
 * appropriately.  If an entry is passed in that does not refer to
 * a file with multiple links, it is returned unchanged.  The intention
 * is that you should be able to simply filter all entries through
 * this machine.
 *
 * To make things more efficient, be sure that each entry has a valid
 * nlinks value.  The hardlink cache uses this to track when all links
 * have been found.  If the nlinks value is zero, it will keep every
 * name in the cache indefinitely, which can use a lot of memory.
 *
 * Note that archive_entry_size() is reset to zero if the file
 * body should not be written to the archive.  Pay attention!
 */
struct archive_entry_linkresolver;

/*
 * There are three different strategies for marking hardlinks.
 * The descriptions below name them after the best-known
 * formats that rely on each strategy:
 *
 * "Old cpio" is the simplest, it always returns any entry unmodified.
 *    As far as I know, only cpio formats use this.  Old cpio archives
 *    store every link with the full body; the onus is on the dearchiver
 *    to detect and properly link the files as they are restored.
 * "tar" is also pretty simple; it caches a copy the first time it sees
 *    any link.  Subsequent appearances are modified to be hardlink
 *    references to the first one without any body.  Used by all tar
 *    formats, although the newest tar formats permit the "old cpio" strategy
 *    as well.  This strategy is very simple for the dearchiver,
 *    and reasonably straightforward for the archiver.
 * "new cpio" is trickier.  It stores the body only with the last
 *    occurrence.  The complication is that we might not
 *    see every link to a particular file in a single session, so
 *    there's no easy way to know when we've seen the last occurrence.
 *    The solution here is to queue one link until we see the next.
 *    At the end of the session, you can enumerate any remaining
 *    entries by calling archive_entry_linkify(NULL) and store those
 *    bodies.  If you have a file with three links l1, l2, and l3,
 *    you'll get the following behavior if you see all three links:
 *           linkify(l1) => NULL   (the resolver stores l1 internally)
 *           linkify(l2) => l1     (resolver stores l2, you write l1)
 *           linkify(l3) => l2, l3 (all links seen, you can write both).
 *    If you only see l1 and l2, you'll get this behavior:
 *           linkify(l1) => NULL
 *           linkify(l2) => l1
 *           linkify(NULL) => l2   (at end, you retrieve remaining links)
 *    As the name suggests, this strategy is used by newer cpio variants.
 *    It's noticeably more complex for the archiver, slightly more complex
 *    for the dearchiver than the tar strategy, but makes it straightforward
 *    to restore a file using any link by simply continuing to scan until
 *    you see a link that is stored with a body.  In contrast, the tar
 *    strategy requires you to rescan the archive from the beginning to
 *    correctly extract an arbitrary link.
