+ * 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.
