# For LON-CAPA 1.2.0 to 2.1.3 (release dates: 8/31/2004 and 3/31/2006) any |
| # ------------------------------------------------------------------------ lond |
# entry logged in lonnet.perm.log for completion of a delayed (critical) |
| |
# transaction lacked the hostID for the remote node to which the command |
| print $fh '<hr><a name="lond"><h2>lond</h2><h3>Log</h3><pre>'; |
# to be completed was sent. |
| |
# |
| |
# Because of this, exclusion of items in lonnet.perm.log for nodes which are |
| |
# no longer part of the cluster from adding to the overall "unsend" count |
| |
# needs additional effort besides the changes made in loncron rev. 1.105. |
| |
# |
| |
# For "S" (completion) events logging in LON-CAPA 1.2.0 through 2.1.3 included |
| |
# "LondTransaction=HASH(hexadecimal)->getClient() :$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). |
