+# entry logged in lonnet.perm.log for completion of a delayed (critical)
+# transaction lacked the hostID for the remote node to which the command
+# to be completed was sent.
+#
+# Because of this, exclusion of items in lonnet.perm.log for nodes which are
+# no longer part of the cluster from adding to the overall "unsend" count
+# needs additional effort besides the changes made in loncron rev. 1.105.
+#
+# For "S" (completion) events logging in LON-CAPA 1.2.0 through 2.1.3 included
+# "LondTransaction=HASH(hexadecimal)->getClient() :$cmd, where the hexadecimal
+# is a memory location, and $cmd is the command sent to the remote node.
+#
+# Starting with 2.2.0 (released 8/21/2006) logging for "S" (completion) events
+# had sethost:$host_id:$cmd after LondTransaction=HASH(hexadecimal)->getClient()
+#
+# Starting with 2.4.1 (released 6/13/2007) logging for "S" replaced echoing the
+# getClient() call with the result of the Transaction->getClient() call itself
+# undef for completion of delivery of a delayed message.
+#
+# The net effect of these changes is that lonnet.perm.log is now accessed three
+# times: (a) oldest record is checked, if earlier than release date for 2.5.0
+# then (b) file is read backwards, with timestamp recorded for most recent
+# instance of logged "S" event for "update" command without "sethost:$host_id:"
+# then (c) file is read forward with records ignored which predate the timestamp
+# recorded in (b), if one was found.
+#
+# In (c), when calculating the unsend total, i.e., the difference between delayed
+# transactions ("D") and sent transactions ("S"), transactions are ignored if the
+# target node is no longer in the cluster, and also (for "update" commands), if
+# the target node is in the list of nodes excluded from the count, in the domain
+# configuration for this machine's default domain. The idea here is to remove
+# delayed "update" commands for nodes for which inbound access to port 5663,
+# is blocked, but are still part of the LON-CAPA network, (i.e., they can still
+# replicate content from other nodes).
