Changelog

dpkg (1.13.22ubuntu4) edgy; urgency=low

  * Implement Breaks.  References:
     http://lists.debian.org/debian-devel/1997/10/msg00643.html
     https://wiki.ubuntu.com/PackageDependencyFieldBreaks

  Decisions made:
  * Specifying Breaks: <virtual package> is fairly meaningless
    without versioned Provides but to make versioned Provides easier
    in the future we support it fully.
  * We do not transitively deconfigure things when we deconfigure
    due to Breaks, just as we don't do so when we deconfigure due
    to removal due to Conflicts (see also #378009).
  * Just as for deconfigure due to Conflicts, we don't deconfigure
    Essential packages without --force-remove-essential.
  * We aren't willing to deconfigure more than one package as a result
    of a single element of a Breaks, just as we aren't willing to
    remove more than one package as a result of a single element of
    a Conflicts.  (Note that this can only occur due to virtual
    packages so it can be worked around by specifying the individual
    real packages instead.)
  * We're happy to deconfigure a package that's on hold even if
    afterwards, due to Breaks, there might not be a way to reconfigure it.
    (This is analogous to the situation where we install a package
    which no longer satisfies the dependencies of an on-hold
    package; it's not clear what the right answer is.)
  * We invent a new --force-breaks which does much the
    same as --force-conflicts.
  * --ignore-depends works for Breaks even though it doesn't work
    for Conflicts.
  * <deconfigured's prerm> deconfigure in-favour <installing> <ver>
      as well as
    <deconfigured's prerm> deconfigure in-favour <installing> <ver> \
                                       removing <conflictor> <ver>
      and of course the corresponding
    <deconfigured's postinst> abort-deconfigure in-favour <installing> <ver>

  Two other changes bundled:
  * mlib contains m_strdup (part of the fix for #379028).
  * Fix for #378003 (multiple deconfigurations).
