  • Comment: Default dapper install doesn't appear to have an admin group

    Dapper does have an admin group; it's strange that you don't have one -- perhaps your Xen image is somewhat nonstandard?.

  • Comment: lzma compression support

    Cool, glad to see its adoption outside Ubuntu! Be sure that gentoo's lzma takes gzip-like arguments with the latter patch, or use the former one. they are mutually exclusive :) (The gzip-like lzma will be the future lzma, so it's better to adopt that :) )

  • Comment: Prevu deletes downloaded files, even if it has failed

    Yeah, it'd be kinda nice if prevu can intelligently parse pbuilder-satisfydepends.pl output to identify what packages need backporting :) This problem I also think needs to be solved in documentation. Prevu really needs some decent documentation rather than a forum post here and there, and a 5-line usage printout on syntax error. Moving to the user's trash is not that ideal either; my home...

  • Comment: Prevu deletes downloaded files, even if it has failed

    The source tarball and extracted source tree are kept together in /var/cache/prevu/src/[process_id].[numeral], and right now they are deleted together. Spawning a subshell of prevu is not really feasible upon build failure because remember that upon building a build dependency, one must run prevu-update to make the base tarball again, and thus make prevu aware of the new packages. And it's...

  • Comment: Prevu deletes downloaded files, even if it has failed

    This is intended behavior that when prevu is directly invoked, it will remove build files regardless of success or failure. If you intend that you'd need to build a package more than once, manually 'apt-get source' it to a location of your choosing, then issue "prevu" while inside the extracted sources. Prevu will make a copy of your source directory and not touch the original at all. I'd...

  • Comment: lzma compression support

    Here's an updated version of this patch, designed for the newer packagings of lzma, such as found in Debian/Ubuntu in 4.43-2 and above. The earlier lzma's also had trouble breaking the 4GB barrier, which is a bad thing (tm) in the context of backups! Now, lzma supports gzip-like syntax with -1 through -9 for compression values and compatible flags to gzip. File Added: flexbackup.

  • lzma compression support

    I implemented lzma compression in the flexbackup script. LZMA is an open source, non-patent-encumbered compressor that compresses around 15% better than bzip2 though it is more time consuming. This is also the compression algorithm in popular 7zip, but p7zip didn't support both stdin and stdout piping in the same command, so I resorted to lzma. Currently it does not allow specifying any...

  • ogmrip randomly segfaults in gnome

    Twice already these few days, ogmrip has segfaulted on me in the middle of a long encode job when I unlocked my GNOME screensaver (ogmrip was in the foreground, screensaver kicked in). I catch a glimpse of the ogmrip window, and then it just dies (Segmentation fault, core dumped). I didn't build ogmrip with debug symbols.. I wish I had, as at the moment I really don't want to go through.

  • mp4 x264/aac: audio does not work

    When encoding to x264/aac with an mp4 container, the audio is screwed up. During the process, mplayer/vlc/xine can all play the audio.* and video.* files correctly. However, when it all ends up in the final mp4, the audio does not play back correctly. mplayer stalls, xine crashes, and VLC recognizes the bad audio channel and only plays video. Sample errors from playing the mp4...
