Hi Kami, Wow - I'm so sorry, I missed your sexy mail for a week; that sucks - over-much merging on another branch :-) Tor has been on FTO, and Fridrich with his head down releasing 3.3.1 (and the Novell LibreOffice product) - which in part explains the lack of response to you (and Steven) - which sucks - sorry guys.

This setting produces 83,91% of original installer size and Oh - nice :-) that solves the install-space problem as well. > In the gray section I tried a special way when I uncompressed every > zip container (ODF, JAR, ZIP, etc) in the installset and every file > contains only stored data without compression.

Oh ! that sounds fun :-) 15Mb for that. Actually on master - we could use flat ODF files and get the same result (for some on-disk size growth) without having to re-compress, and they're dead fast in master. So - personally, I find it amazing that ZIP is better than LZMA - ever, it is such an older compression algorithm, and this flies in the face of everything I've seen in practise with it [ eg. we use LZMA for our RPMs in openSUSE these days AFAIR, better than bzip2, which in turn was better than .tgz (essentially zip) ]. It'd be great to commit the first patch but can we instead hack: solenv/bin/modules/installer/globals.pm to patch: $cabfilecompressionlevel = 7; rather than hard-coding that and leaving the variable there. The second - can you really confirm that LZMA is worse than zip ? Anyhow - great work :-) Michael. -- michael.me...@novell.com <><, Pseudo Engineer, itinerant idiot _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
