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. */ __LA_DECL struct archive_entry_linkresolver *archive_entry_linkresolver_new(void); __LA_DECL void archive_entry_linkresolver_set_strategy( struct archive_entry_linkresolver *, int /* format_code */); __LA_DECL void archive_entry_linkresolver_free(struct archive_entry_linkresolver *); __LA_DECL void archive_entry_linkify(struct archive_entry_linkresolver *, struct archive_entry **, struct archive_entry **); __LA_DECL struct archive_entry *archive_entry_partial_links( struct archive_entry_linkresolver *res, unsigned int *links); #ifdef __cplusplus } #endif /* This is meaningless outside of this header. */ #undef __LA_DECL #endif /* !ARCHIVE_ENTRY_H_INCLUDED */ Index: vendor/libarchive/dist/libarchive/archive_write_disk_posix.c =================================================================== --- vendor/libarchive/dist/libarchive/archive_write_disk_posix.c (revision 348976) +++ vendor/libarchive/dist/libarchive/archive_write_disk_posix.c (revision 348977) @@ -1,4483 +1,4474 @@ /*- * Copyright (c) 2003-2010 Tim Kientzle * Copyright (c) 2012 Michihiro NAKAJIMA * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
