[Lzip-bug] LZIP codec for 7zip in p7zip-16.02

I tried to add your lzip support to p7zip-16.02 (newest one) but somehow didn't work. After compilation 7z does not recognize .lz files. $ 7z e blabla.lz Error: Can not open file as archive I applied patch manually (as automatic patch was rejected), obviously without `LzHandler.cpp', same l

2017-06-26 Thread wrotycz
Helo, that seems to be too complicated. IMHO as an archiver it should be able to "recreate original" file with original name, time stamps and probably permissions (these permissions are still more debatable). That's my personal opinion anyway. With meta one could utilise trailing data space b

The match length is not stored, but the other info can be retrieved with the --list option like this: $ lzip -lvv linux-libre-3.12.5-gnu-mm.tar. Thank you for info. I didn't know about `v' modifier to the `-l' option and was wandering whether it is possible to do without decompressing at al

If the changes required are easy, they may be ready in a few days. Else it may take longer. BTW, has anybody verified if this change is worth the effort? I.e., has LZMA compression any advantages over gzip compression for kernel modules? I can test it if it's not too complicated. I mean I

LZSS is not LZ77

I was reading about LZSS and it sounded like LZ77, or rather what everyone calls LZ77, and the definition, even on wikipedia [1] it notices that 'Many popular archivers like PKZip, ARJ, RAR, ZOO, LHarc use LZSS rather than LZ77 as the primary compression algorithm; the encoding of literal charac
