-# currently only used to determine if we should or shouldn't announce
-# the availability of a new CPAN module
-# but now we try to use it for dependency tracking. For that to happen
+# 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: run the queue as the user suggested. When a dependency is
-# detected check if it is in the queue. If so, rearrange, otherwise
-# unshift it on the queue.
+# 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
