corrections to the Windows support to reconcile differences between Visual Studio and Cygwin. Includes parts of revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886. Of particular note, r886 overhauled the UTF-8/Unicode conversions to work correctly regardless of whether the local system uses 16-bit or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision also added a preference for wcrtomb() (which is thread-safe) on platforms that support it.

|
|
* 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!

/*
|
|
* 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.
