# |
|
# 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). |
