This is one of the most powerful functions of swim because besides
rebuilding the not-installed databases averting a long wait, it creates
a report which can compare changes within one distribution, or this
function can be tricked into comparing the differences between two
distributions. This also quickly updates the DF databases or
not-installed databases when a new package(s) are installed or downloaded.
=cut
sub update_packages_ndb {
=pod
This function differs from SWIM::DB::db because rather then checking
the status file, it compares the Packages file(s) to the status
database created by swim.
For normal upadating (not ndb ran automatically) SWIM::NDB_Init is used to
figure out what Packages databases to use for comparison. --ndb run
automatically will also be dealt with.

Basically, if a package is new its information can be placed into the
specified databases. If a package already exists and the version has
changed, then this package will be updated, and specific information like
group and status will be compared. The version change will also be
compared..is it older, newer, debian-revision change? Packages which are
gone will have their information removed from the specified databases.
# REPORT #
A report will be kept, this allows changes within a distribution to be
recorded, or alternatively two different distributions can be compared by
tricking swim into thinking that the same distribution is being looked at.
The format is something like a passwd file, except that it is divided
by ! (exclamations) - fortunately no packages have this - though sometimes
files do (very rare), exclamations in the Description field will be
coverted to a pound #. Control fields are stripped of their Field:.
(this all on one line)
GONE or CHANGED or NEW or SAME!
packagename!Description!
current_version!old_version!
current_group!old_group!
current_status!old_status! # Both for installed and not-installed (r<>=)
current_arch!old_arch!
current_dist!old_dist!
current_priority!old_priority!
present_maintainer!old_maintainer!
current_essential!old_essential!
current_source!old_source! # Weird if it changes
current_IS!old_IS! # Installed_Size
current_size!old_size!
As you can see this format provides lots of information with 25 fields,
even more information than is needed, and the report can be read into a
hash of hashes quite easily, other ways can be used, too. Fields without
a value will just be empty (!!). The report will be available with the
--report option and will be dated, since it will be made new for each
dist-dist comparison. It's not necessary to use a Contents database, so
these reports can be generated very fast. But, it would be interesting to
see file differences in two distinct Distributions..Suse versus Debian,
this may come in the future .. although the author has already written
such a program (which doesn't use databases).
Important:
Existing databases are used and updated, so for research purposes copies
of the databases in the default directory should be placed in an
alternative directory and --dbpath and/or --root used.

# GONE #
# for some reason the value for "/." gets corrupted sometimes after
# going through the @GONE loop .. so we will just carry it down, and
# this seems to work fine. As though that wasn't enough, sometimes
# the same monster exists in both non-us and main, so we will have
# to make provisions for this situation, otherwise the packages
# relationship to changes will be incorrectly recognized. This
# means -qan will provide a strange listing with two packages with
# the same name and then will be altered after
# --ndb. This causes all kinds of complications because nstatus is
# indexed with the name not the name_version, but /. can include
# both. So for these two timers or more, we will watch for them,
# and always use the newest version or the lack of it from both to
# determine whether the package(s) is gone, new, changed, and
# rewrite the entry for the two timer to be the newest, actually
# they should be handled in the initial creation. What this all
# means is that the databases as well as querying capabilities will
# be designed to handle multiple versions of the same package.
#
# Actually, the best solution is to provide no provisions for
# packages which exist with more than one version, just
# use the newest version of the package getting rid of all
# references to the packages for both --initndb & --ndb. This
# situation can also occur when swim fails to notice that two dists
# are unique (i.e. personal vs Debian) - a problem soon to be
