* 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_link_resolver_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 noticably 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.
