The previous rdup roadmap has been implemented. I'm now working on the post 0.6.1 items and added a few new features:

• The regular expressions are now pcre (Perl Compatible Regular Expressions), this adds an extra dependency to rdup for this library. But these are so much more powerful that I think it is worth it.

• For completeness sake I added: sockets, named pipes, character devices and block devices as recognized file types to rdup. One side effect of this is that the filesize (%s) is (again) overloaded to mean minor,major just as in the ls -l output when an character or block devices is printed.

  The rdup-utils currently ignore these extra file types.

  So lets say I have this directory:

  
  $ ls -l A
  total 0
  -rwsrwsr-x 1 miekg miekg    0 Aug 11 12:45 blaat*
  -rw-rw-r-- 1 miekg miekg    0 Aug 11 16:30 ff
  prw-rw-r-- 1 miekg miekg    0 Aug 11 16:34 fifo|
  brw-r--r-- 1 root  root  8, 0 Aug 11 16:24 sda
  crw-r--r-- 1 root  root  8, 0 Aug 11 16:24 sdb
  srwxrwxrwx 1 miekg miekg    0 Aug 11 16:58 socket=
  

  rdup will now print this as:

  
  ./rdup /dev/null A
  +d 0755 0 0 5 0 /home
  +d 0751 1000 1000 11 0 /home/miekg
  +d 0711 1000 1000 15 0 /home/miekg/svn
  +d 0700 1000 1000 20 0 /home/miekg/svn/rdup
  +d 0775 1000 1000 26 0 /home/miekg/svn/rdup/trunk
  +d 0775 1000 1000 28 0 /home/miekg/svn/rdup/trunk/A
  +- 6775 1000 1000 34 0 /home/miekg/svn/rdup/trunk/A/blaat
  +- 0664 1000 1000 31 0 /home/miekg/svn/rdup/trunk/A/ff
  +p 0664 1000 1000 33 0 /home/miekg/svn/rdup/trunk/A/fifo
  +b 0644 0 0 32 8,0 /home/miekg/svn/rdup/trunk/A/sda
  +c 0644 0 0 32 8,0 /home/miekg/svn/rdup/trunk/A/sdb
  +s 0777 1000 1000 35 0 /home/miekg/svn/rdup/trunk/A/socket
  

  So there as 4 new types: p, b, c and s.

• The move to GNode might be needed to allow rdup to reverse print the filelist (i.e. rdup /dev/null ~/bin | tac). In 0.6.2 a -R flag is added that makes this possible. The internal structures in rdup are still GTree's (balanced binary trees). The -R feature is implemented by putting all elements in a linked list (GList) and reverse printing that.
