[Cupt-devel] Bug#725979: cupt: Support version 3 of apt's Pre-Install-Pkgs

[James McCoy]

Package: cupt
Version: 2.6.1
Severity: wishlist

Support for version 3 requires a few changes.

- The version header line should be "VERSION 3"
- The native architecture should be emitted as "APT::Architecture=..."
- The description line for each package is broken into the following fields:
  pkg_name old_ver old_arch old_ma direction new_ver new_arch new_ma filename/action

Independent of this, apt also grew the ability to specify that a tool should
receive this information on a specific fd.

- The tool can request that it receives this info on a specific fd via
  DPkg::Tools::options::cmd::InfoFd.  If this is set, APT_HOOK_INFO_FD should be
  set in the environment that runs the tool so that it can determine what fd to
  open.

See the following commits in apt for more information.

apt-listbugs' implementation of support for this may also be of use:
