Re: Help You. Identify the non-optified apps.

Root is on a separate 256M high-speed flash chip. I've heard that this was the largest available (integrated with the processor) at the time.

Re: Help You. Identify the non-optified apps.

Ah. that makes sense. it's like flash0 and flash1 on the PSP.

I see. This chip also gets flashed when one uses the Flashing Tool for the n900?

Re: Help You. Identify the non-optified apps.

If you just flash the main firmware, this is the only chip that gets flashed. The eMMC firmware will flash the 32GB built-in storage (but should rarely be needed).

Re: Help You. Identify the non-optified apps.

Hmm. can the rootfs somehow be mounted when pluggin the n900 to a pc? from what I saw. It seems only MyDocs appears in mass storage mode.....

It'll make going through the files on it easier. instead of the terminal.

Re: Help You. Identify the non-optified apps.

Nope - mass storage mode requires unmounting the filesystem (as it's exported at a low level). This obviously can't be done with the rootfs.

yes that's possible, using sshfs.

Re: Help You. Identify the non-optified apps.

another noob question in regards to this, after deleting apps, the rootfs space does not seem to be recovered, even after a reboot. i had installed mplayer (19.4M). rootfs usage was 189M used , according to diskusage

then i used this cmd

dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' | sort -k2 -n

and it was shown at the bottom of the list (sorted by size)

i uninstalled it, rebooted and diskusage still showed 189M used. running the above commandline once again showed it was still there.

dpkg -L mplayer

returned that package mplayer does not contain any files?!

so, my question; how do you purge installed files sitting on rootfs?

Copy&paste output of these commands:
dpkg -l mplayer
ls -l /usr/bin/mplayer

Re: Help You. Identify the non-optified apps.

Just for fun, I've knocked together a quick perl script that can find the non-optified disk usage for a given package:

Code:

#!/usr/bin/perl



%known_optified = ();

%known_nonoptified = ();



sub is_secretly_optified($) {

  my ($file) = @_;



  # print "testing $file\n";



  if($known_optified{$file}) {

     # print "known optfified $file\n";

    return 1;

  }



  if($known_nonoptified{$file}) {

    # print "known nonoptfified $file\n";

    return 0;

  }



  unless($file) {

    return 0;

  }

  my $orig = $file;



  unless( -l $file) {

    $file =~ s/\/[^\/]*$//;

    if(is_secretly_optified($file)) {

      $known_optified{$orig} = 1;

      return 1;

    } else {

      $known_nonoptified{$orig} = 1;

      return 0;

    }

  }



  my $lsresult = `/bin/ls -l $file`;

  chomp($lsresult);



  if($lsresult =~ /->\s+(.*)/) {

    my $target = $1;

    # print "found symlink to $target\n";

    if($target =~ /^\/opt/ or $target =~ /^\/home/) {

      # print "remembering $target is optified?\n";

      # print "remembering $orig is optified?\n";

      $known_optified{$orig} = 1;

      return 1;

    } else {

      if(is_secretly_optified($target)) {

        $known_optified{$orig} = 1;

        return 1;

      } else {

        $known_nonoptified{$orig} = 1;

        return 0;

      }

    }

  }

}



while(<>) {

  unless($currentfile eq $ARGV) {

    $currentfile = $ARGV;

    if($out) {

      if($total >= 1024) {

        $total = sprintf("%0.2fM", $total / 1024);

      } else {

        $total = sprintf("%0.2fK", $total);

      }

      print "$out$currentpkg : total non-opt usage: "

            . "$total\n----------\n";

    }

    $out = undef;

    $total = undef;

    $currentfile = $ARGV;



    $currentpkg = $currentfile;

    $currentpkg =~ s/\.md5sums//;

    $currentpkg =~ s/.*\///;

  }



  s/^\S+\s+//;

  $suspect = "/$_";



  $du = undef;

  unless(/^opt/ or /^home/ or /^usr\/share\/(man|doc)\//) {

    next if(is_secretly_optified($suspect));

    $du = `du -s $suspect`;

    chomp $du;

    if($du =~ /^(\d+)/) {

      $total += $1;

      if($1 >= 1024) {

        $val  = sprintf("%0.2fM", $1 / 1024);

      } else {

        $val  = sprintf("%0.2fK", $1);

      }



      $du =~ s/^\d+/$val/;

    }

    $out .= "$currentpkg : $du\n";

  }

}





if($out) {

  if($total >= 1024) {

    $total = sprintf("%0.2fM", $total / 1024);

  } else {

    $total = sprintf("%0.2fK", $total);

  }

  print "$out$currentpkg : total non-opt usage: "

        . "$total\n---------\n";

}

If you save it as /usr/local/bin/find_non_opt_files.pl, you can run it giving /var/lib/dpkg/info/<pkgname>.md5sums as an argument. Here is the commandline and output running it on a sample package:

Quote:

~# /usr/local/bin/find_non_opt_files.pl /var/lib/dpkg/info/burgerspace.md5sums
burgerspace : 4.00K /usr/share/pixmaps/burgerspace.xpm
burgerspace : 4.00K /usr/share/applications/hildon/burgerspace.desktop
burgerspace : 8.00K /usr/share/icons/hicolor/scalable/hildon/burgerspace.png
burgerspace : 4.00K /usr/share/icons/hicolor/48x48/hildon/burgerspace.png
burgerspace : 4.00K /usr/share/icons/hicolor/32x32/hildon/burgerspace.png
burgerspace : 4.00K /usr/share/menu/burgerspace
burgerspace : total non-opt usage: 28.00K
-------------------------------------------------------

It will also take multiple arguments, so to see the results for all packages:

Code:

/usr/local/bin/find_non_opt_files.pl /var/lib/dpkg/info/*.md5sums

which will produce a lot of output, including about system packages..

Edit: Just to add, this hasn't been security audited, so if you should have a line like "1234 asdf;rm -rf /" in one of your *.md5sums, or other similar problems, you're on your own!

Further Edit: Script amended to take account of symlinked directories as per posts around http://talk.maemo.org/showthread.php...655#post438655

One more edit: don't count files in /home as non-optified
