I started using lzop, and it has been icnredibly nice for massive source compilations, the decompression time is fast, speeding up installation time.
However, there is extra work I had to do that tar+bzip2 and tar+gzip have spoiled me. So, I added tar+lzo support (via the lzop program) below and attatched is the patch to make this happen, against tar-1.16.1, but should work with some olderones Submitted By: Kevin Day <kevin AT kevux DOT org> Date: 2006-12-30 Initial Package Version: 1.16.1 Upstream Status: Submitted upstream Origin: Wanted to do tar -xf on lzo files (.tar.lzo) Description: Add support for lzo/lzop decompression http://www.oberhumer.com/opensource/lzo/ http://www.lzop.org/ --- tar-1.16.1/src/buffer.c.orig 2006-12-30 10:40:59.000000000 -0600 +++ tar-1.16.1/src/buffer.c 2006-12-30 11:54:33.000000000 -0600 @@ -196,7 +196,8 @@ ct_none, ct_compress, ct_gzip, - ct_bzip2 + ct_bzip2, + ct_lzop }; struct zip_magic @@ -213,6 +214,7 @@ { ct_compress, 2, "\037\235", "compress", "-Z" }, { ct_gzip, 2, "\037\213", "gzip", "-z" }, { ct_bzip2, 3, "BZh", "bzip2", "-j" }, + { ct_lzop, 4, "\211LZO", "lzop", "-q" }, }; #define NMAGIC (sizeof(magic)/sizeof(magic[0])) --- tar-1.16.1/src/tar.c.orig 2006-12-30 10:41:04.000000000 -0600 +++ tar-1.16.1/src/tar.c 2006-12-30 12:06:10.000000000 -0600 @@ -572,6 +572,8 @@ N_("create archive with volume name TEXT; at list/extract time, use TEXT as a globbing pattern for volume name"), GRID+8 }, {"bzip2", 'j', 0, 0, N_("filter the archive through bzip2"), GRID+8 }, + {"lzop", 'q', 0, 0, + N_("filter the archive through lzop"), GRID+8 }, {"gzip", 'z', 0, 0, N_("filter the archive through gzip"), GRID+8 }, {"gunzip", 0, 0, OPTION_ALIAS, NULL, GRID+8 }, @@ -1340,6 +1342,10 @@ absolute_names_option = true; break; + case 'q': + set_use_compress_program_option ("lzop"); + break; + case 'r': set_subcommand_option (APPEND_SUBCOMMAND); break; -- Kevin Day
