2012-03-06update seamless uncompression codeDenys Vlasenko
This change makes "tar tf hello_world.txz" work without adding special-casing for ".txz" extension. It also removes ever-growing magic checking code in rpm2cpio and get_header_tar - we reuse one which lives in setup_unzip_on_fd. function old new delta unpack_gz_stream 7 566 +559 check_signature16 - 70 +70 setup_unzip_on_fd 99 142 +43 handle_SIGCHLD - 41 +41 unpack_bz2_stream 342 376 +34 unzip_main 2352 2385 +33 bbunpack 503 533 +30 open_transformer 74 102 +28 unpack_Z_stream 1278 1304 +26 unpack_gunzip 101 123 +22 init_transformer_aux_data - 18 +18 unpack_xz_stream 2388 2402 +14 open_zipped 131 141 +10 rpm_main 1358 1363 +5 get_header_tar_lzma 52 57 +5 get_header_tar_bz2 52 57 +5 unpack_lzma_stream 2698 2702 +4 hash_find 234 233 -1 get_header_tar 1759 1733 -26 get_header_tar_gz 92 57 -35 unpack_uncompress 51 12 -39 rpm2cpio_main 201 147 -54 unpack_unxz 67 12 -55 unpack_bz2_stream_prime 55 - -55 get_header_tar_Z 86 - -86 unpack_gz_stream_with_info 539 - -539 ------------------------------------------------------------------------------ (add/remove: 3/3 grow/shrink: 14/6 up/down: 947/-890) Total: 57 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
