# One use of the queue is to determine if we should or shouldn't
# announce the availability of a new CPAN module
# Now we try to use it for dependency tracking. For that to happen
# we need to draw a dependency tree and do the leaves first. This can
# easily be reached by running CPAN.pm recursively, but we don't want
# to waste memory and run into deep recursion. So what we can do is
# this:
# CPAN::Queue is the package where the queue is maintained. Dependencies
# often have high priority and must be brought to the head of the queue,
# possibly by jumping the queue if they are already there. My first code
# attempt tried to be extremely correct. Whenever a module needed
# immediate treatment, I either unshifted it to the front of the queue,
# or, if it was already in the queue, I spliced and let it bypass the
# others. This became a too correct model that made it impossible to put
# an item more than once into the queue. Why would you need that? Well,
# you need temporary duplicates as the manager of the queue is a loop
# that
#
# (1) looks at the first item in the queue without shifting it off
#
# (2) cares for the item
#
# (3) removes the item from the queue, *even if its agenda failed and
# even if the item isn't the first in the queue anymore* (that way
# protecting against never ending queues)
#
# So if an item has prerequisites, the installation fails now, but we
# want to retry later. That's easy if we have it twice in the queue.
#
# I also expect insane dependency situations where an item gets more
# than two lives in the queue. Simplest example is triggered by 'install
# Foo Foo Foo'. People make this kind of mistakes and I don't want to
# get in the way. I wanted the queue manager to be a dumb servant, not
# one that knows everything.
#
# Who would I tell in this model that the user wants to be asked before
# processing? I can't attach that information to the module object,
# because not modules are installed but distributions. So I'd have to
# tell the distribution object that it should ask the user before
# processing. Where would the question be triggered then? Most probably
# in CPAN::Distribution::rematein.
# Hope that makes sense, my head is a bit off:-) -- AK

# Those are my current opinions. It is also my optinion that polite
