[Bug 21837] Re: debdelta integration / zsync support

[Julian Andres Klode]

Work on delta debs was being done in
https://wiki.debian.org/Teams/Dpkg/Spec/DeltaDebs amongst other places,
but it kind of stopped a bit. Deltas are getting harder and harder to
justify with increasing speeds and less and less data caps, but it's
certainly something I'm interested in developing.

I believe my format is fairly solid. The problem with debdelta was that
it was incredibly slow, to the point where using it outside of dialup
(well, I did not measure it, it might be a hyperbole) would basically be
pointless.

** Changed in: apt (Ubuntu)
       Status: Confirmed => Triaged

** No longer affects: apt

Title:
  debdelta integration / zsync support

Status in apt package in Ubuntu:
  Triaged
Status in apt package in Baltix:
  Confirmed

Bug description:
  Ubuntu should, like Mandrake 10.2, Firefox 1.5 and Windows, update packages
  using binary patches instead of by re-downloading entire packages. This would be
  especially helpful when running beta versions of software which change daily.
