Add "$(OBJS): config.h" so everything will rebuild if config.h changes.

URGENT ---------------------------------------------------------------


IMPORTANT ------------------------------------------------------------

Cross-test versions

  Part of the regression suite should be making sure that we don't
  break backwards compatibility: old clients vs new servers and so
  on.  Ideally we would test the cross product of versions.  

  It might be sufficient to test downloads from well-known public
  rsync servers running different versions of rsync.  This will give
  some testing and also be the most common case for having different
  versions and not being able to upgrade.

use chroot

  If the platform doesn't support it, then don't even try.

  If running as non-root, then don't fail, just give a warning.
  (There was a thread about this a while ago?)

--files-from

  Avoids traversal.  Better option than a pile of --include statements
  for people who want to generate the file list using a find(1)
  command or a script.

Performance

  Traverse just one directory at a time.  Tridge says it's possible.
 
  Can possibly also be smarter about memory use while looking for hard
  links by reducing the refcount as we find alternative names.

IPv6

  Define a syntax for IPv6 literal addresses.  Since they include
  colons, they tend to break most naming systems, including ours.
  Based on the HTTP IPv6 syntax, I think we should use
 
     rsync://[::1]/foo/bar
     [::1]::bar

  which should just take a small change to the parser code.

Errors

  If we hang or get SIGINT, then explain where we were up to.  Perhaps
  have a static buffer that contains the current function name, or
  some kind of description of what we were trying to do.  This is a
  little easier on people than needing to run strace/truss.

  "The dungeon collapses!  You are killed."  Rather than "unexpected
  eof" give a message that is more detailed if possible and also more
  helpful.  


PLATFORMS ------------------------------------------------------------

Win32

  Don't detach, because this messes up --srvany.

  http://sources.redhat.com/ml/cygwin/2001-08/msg00234.html

  According to "Effective TCP/IP Programming" (??) close() on a socket
  has incorrect behaviour on Windows -- it sends a RST packet to the
  other side, which gives a "connection reset by peer" error.  On that
  platform we should probably do shutdown() instead.  However, on Unix
  we are correct to call close(), because shutdown() discards
  untransmitted data.

BUILD FARM -----------------------------------------------------------

Add machines

  AMDAHL UTS (Dave Dykstra)

  Cygwin (on different versions of Win32?)

  HP-UX variants (via HP?)

  SCO

NICE -----------------------------------------------------------------

--no-detach and --no-fork options

  Very useful for debugging.  Also good when running under a
  daemon-monitoring process that tries to restart the service when the
  parent exits.

hang/timeout friendliness

  On 

internationalization

  Change to using gettext().  Probably need to ship this for platforms
  that don't have it.  

  Solicit translations.

  Does anyone care?

rsyncsh 

   Write a small emulation of interactive ftp as a Pythonn program
   that calls rsync.  Commands such as "cd", "ls", "ls *.c" etc map
   fairly directly into rsync commands: it just needs to remember the
   current host, directory and so on.  We can probably even do
   completion of remote filenames.
