142 * You can think of this as "struct stat" with some text fields added in.
144 * TODO: Add "comment", "charset", and possibly other entries that are
145 * supported by "pax interchange" format. However, GNU, ustar, cpio,
146 * and other variants don't support these features, so they're not an
147 * excruciatingly high priority right now.
149 * TODO: "pax interchange" format allows essentially arbitrary
150 * key/value attributes to be attached to any entry. Supporting
151 * such extensions may make this library useful for special
152 * applications (e.g., a package manager could attach special
153 * package-management attributes to each entry).
156 struct archive_entry;
159 * File-type constants. These are returned from archive_entry_filetype()
160 * and passed to archive_entry_set_filetype().
162 * These values match S_XXX defines on every platform I've checked,
163 * including Windows, AIX, Linux, Solaris, and BSD. They're
164 * (re)defined here because platforms generally don't define the ones
165 * they don't support. For example, Windows doesn't define S_IFLNK or
166 * S_IFBLK. Instead of having a mass of conditional logic and system
167 * checks to define any S_XXX values that aren't supported locally,
168 * I've just defined a new set of such constants so that
169 * libarchive-based applications can manipulate and identify archive
170 * entries properly even if the hosting platform can't store them on
173 * These values are also used directly within some portable formats,
174 * such as cpio. If you find a platform that varies from these, the
175 * correct solution is to leave these alone and translate from these
176 * portable values to platform-native values when entries are read from
177 * or written to disk.
180 * In libarchive 4.0, we can drop the casts here.
181 * They're needed to work around Borland C's broken mode_t.

617 * Utility to match up hardlinks.
619 * The 'struct archive_entry_linkresolver' is a cache of archive entries
620 * for files with multiple links. Here's how to use it:
621 * 1. Create a lookup object with archive_entry_linkresolver_new()
622 * 2. Tell it the archive format you're using.
623 * 3. Hand each archive_entry to archive_entry_linkify().
624 * That function will return 0, 1, or 2 entries that should
626 * 4. Call archive_entry_linkify(resolver, NULL) until
627 * no more entries are returned.
628 * 5. Call archive_entry_linkresolver_free(resolver) to free resources.
630 * The entries returned have their hardlink and size fields updated
631 * appropriately. If an entry is passed in that does not refer to
632 * a file with multiple links, it is returned unchanged. The intention
633 * is that you should be able to simply filter all entries through
636 * To make things more efficient, be sure that each entry has a valid
637 * nlinks value. The hardlink cache uses this to track when all links
638 * have been found. If the nlinks value is zero, it will keep every
639 * name in the cache indefinitely, which can use a lot of memory.
641 * Note that archive_entry_size() is reset to zero if the file
642 * body should not be written to the archive. Pay attention!
644 struct archive_entry_linkresolver;
647 * There are three different strategies for marking hardlinks.
648 * The descriptions below name them after the best-known
649 * formats that rely on each strategy:
651 * "Old cpio" is the simplest, it always returns any entry unmodified.
652 * As far as I know, only cpio formats use this. Old cpio archives
653 * store every link with the full body; the onus is on the dearchiver
654 * to detect and properly link the files as they are restored.
655 * "tar" is also pretty simple; it caches a copy the first time it sees
656 * any link. Subsequent appearances are modified to be hardlink
657 * references to the first one without any body. Used by all tar
658 * formats, although the newest tar formats permit the "old cpio" strategy
659 * as well. This strategy is very simple for the dearchiver,
660 * and reasonably straightforward for the archiver.
661 * "new cpio" is trickier. It stores the body only with the last
662 * occurrence. The complication is that we might not
663 * see every link to a particular file in a single session, so
664 * there's no easy way to know when we've seen the last occurrence.
665 * The solution here is to queue one link until we see the next.
666 * At the end of the session, you can enumerate any remaining
667 * entries by calling archive_entry_linkify(NULL) and store those
668 * bodies. If you have a file with three links l1, l2, and l3,
669 * you'll get the following behavior if you see all three links:
670 * linkify(l1) => NULL (the resolver stores l1 internally)
671 * linkify(l2) => l1 (resolver stores l2, you write l1)
672 * linkify(l3) => l2, l3 (all links seen, you can write both).
673 * If you only see l1 and l2, you'll get this behavior:
674 * linkify(l1) => NULL
676 * linkify(NULL) => l2 (at end, you retrieve remaining links)
677 * As the name suggests, this strategy is used by newer cpio variants.
678 * It's noticeably more complex for the archiver, slightly more complex
679 * for the dearchiver than the tar strategy, but makes it straightforward
680 * to restore a file using any link by simply continuing to scan until
681 * you see a link that is stored with a body. In contrast, the tar
682 * strategy requires you to rescan the archive from the beginning to
683 * correctly extract an arbitrary link.
