[Bug 878180] Re: missing Breaks/Replaces

[Robie Basak]

Following Dave's query on the Lucid -> Precise path, I've gone back to
look at the files that have been replaced between all three versions. To
stop this getting too confusing for me, I wrote a script to do it. My
script found a couple of adjustments:

1) Some of my new Breaks/Replaces entries were unnecessarily restrictive
on versioning; for binary packages that no longer exist, it's sufficient
just to name them.

2) One package (libxmlrpc-c3-dev) vanished in Oneiric but has reappeared
in Precise, so the Replaces line now needs a version restriction
applied, since the Precise version of libxmlrpc-c3-dev has no
replacements made by the Precise version of libxmlrpc-core-c3-dev.

I've updated my branch, attached the analysis from my script, and
uploaded the script itself to http://bazaar.launchpad.net/~racb/+junk
/deb-find-breaks/revision/1/deb-find-breaks.py

Title:
  missing Breaks/Replaces

Status in “xmlrpc-c” package in Ubuntu:
  Confirmed

Bug description:
  The xmlrpc-c binary packages have been reorganised in the upload with
  binaries currently waiting in NEW.  Some of these overlap with
  binaries that were previously in Ubuntu (they may have been Ubuntu-
  specific), and not all the required Breaks/Replaces fields are
  present.  In particular, I believe you need:

    libxmlrpc-c++4 Breaks/Replaces: libxmlrpc-c3-0 (<< 1.16.33-3.1ubuntu1)
    libxmlrpc-core-c3 Breaks/Replaces: libxmlrpc-core-c3-0 (<< 1.16.33-3.1ubuntu1)

  (Some of the binaries in this source package already use
  Conflicts/Replaces pairs for similar purposes.  This is discouraged by
  the Debian policy manual nowadays in favour of Breaks/Replaces,
  although quite a few packages still use the older incorrect approach.)
