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 */ diff --git a/3rdparty/libarchive/c/archive_entry_copy_bhfi.c b/3rdparty/libarchive/c/archive_entry_copy_bhfi.c deleted file mode 100644 index 77bf38e..0000000 --- a/3rdparty/libarchive/c/archive_entry_copy_bhfi.c +++ /dev/null @@ -1,75 +0,0 @@ -/*- - * Copyright (c) 2003-2007 Tim Kientzle - * 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.

Here's an example of a structure of "lzma alone" - * format: - * - * $ cat /bin/ls | lzma | xxd | head -n 1 - * 00000000: 5d00 0080 00ff ffff ffff ffff ff00 2814 - * - * 5 bytes 8 bytes n bytes - * - * - * lzma_params is a 5-byte blob that has to be decoded to extract - * parameters of this LZMA stream. The uncompressed_size field is an - * uint64_t value that contains information about the size of the - * uncompressed file, or UINT64_MAX if this value is unknown. - * The part is the actual lzma-compressed data stream. - * - * Now here's the structure of the stream inside the ZIPX file: - * - * $ cat stream_inside_zipx | xxd | head -n 1 - * 00000000: 0914 0500 5d00 8000 0000 2814 .... .... - * - * 2byte 2byte 5 bytes n bytes - * - * - * This means that the ZIPX file contains an additional magic1 and - * magic2 headers, the lzma_params field contains the same parameter - * set as in the "lzma alone" format, and the field is the - * same as in the "lzma alone" format as well. Note that also the zipx - * format is missing the uncompressed_size field. - * - * So, in order to use the "lzma alone" decoder for the zipx lzma - * stream, we simply need to shuffle around some fields, prepare a new - * lzma alone header, feed it into lzma alone decoder so it will - * initialize itself properly, and then we can start feeding normal - * zipx lzma stream into the decoder. - */ - - /* Read magic1,magic2,lzma_params from the ZIPX stream. */ - if((p = __archive_read_ahead(a, 9, NULL)) == NULL) { - archive_set_error(&a->archive, ARCHIVE_ERRNO_FILE_FORMAT, - "Truncated lzma data"); - return (ARCHIVE_FATAL); - } - - if(p[2] != 0x05 || p[3] != 0x00) { - archive_set_error(&a->archive, ARCHIVE_ERRNO_FILE_FORMAT, - "Invalid lzma data"); - return (ARCHIVE_FATAL); - } - - /* Prepare an lzma alone header: copy the lzma_params blob into - * a proper place into the lzma alone header. */ - memcpy(&alone_header.bytes[0], p + 4, 5); - - /* Initialize the 'uncompressed size' field to unknown; we'll manually - * monitor how many bytes there are still to be uncompressed. */ - alone_header.uncompressed_size = UINT64_MAX; - - if(!zip->uncompressed_buffer) { - zip->uncompressed_buffer_size = 256 * 1024; - zip->uncompressed_buffer = - (uint8_t*) malloc(zip->uncompressed_buffer_size); - - if (zip->uncompressed_buffer == NULL) { - archive_set_error(&a->archive, ENOMEM, - "No memory for lzma decompression"); - return (ARCHIVE_FATAL); - } - } - - zip->zipx_lzma_stream.next_in = (void*) &alone_header; - zip->zipx_lzma_stream.avail_in = sizeof(alone_header); - zip->zipx_lzma_stream.total_in = 0; - zip->zipx_lzma_stream.next_out = zip->uncompressed_buffer; - zip->zipx_lzma_stream.avail_out = zip->uncompressed_buffer_size; - zip->zipx_lzma_stream.total_out = 0; - - /* Feed only the header into the lzma alone decoder.
