|
* 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!

/*
|
|
|
|
|
* 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.
