Add the APT::Cache::ShowVersion=1 option to the apt-cache calls to
turn on version reporting.
Once this change has gone into apt-cache as well, we're all set.
Changes:
Use/parse output from a newer version of apt so that "apt-cache
depends" will include version information on dependencies.
All tracking of packages now include versions, so we pass around
hashes of {package name, comparison op, version} everywhere instead of
simply passing package names as strings.
WIP for now; apt-cache is likely to change format before we ship
this...
+ Track whether a dependency chain is caused by a hard dependency
(Depends) or soft (Recommends/Suggests). If we fail to add a package
down the chain on a *soft* dependency, don't invalidate the entire
chain.
+ When checking OR dependencies, *first* check to see if any of the
options are already installed *before* trying to install the first
option. Helps a lot with circular deps such as task-lxde-desktop ->
task-desktop -> (task-gnome-desktop | task-lxde-desktop | etc.); in
this case, of course task-lxde-desktop should satisfy the OR dep.
If $DI_CODENAME is ever set to a bad value, one would end up trying to
use a non-existing debian-installer, resulting in non-bootable images
way later. To detect that much earlier, make sure all locations
(computed from $CODENAME and $DI_CODENAME) are directories.
menu (pulled in by desktop tasks),
aptitude (pulled in by debootstap, and may be demoted to optional),
alsa-utils, alsa-base (pulled in by task-desktop),
mdetect, read-edid (no longer used by xorg),
grub (handed by generate_di+k_list),
deborphan, debfoster, localepurge (expert user stuff),
chdrvfont (no such package any more)
* Updated generate_di+k_list to match more closely the current
packages d-i apt-installs.
