- rearranged code to reduce cyclic dependencies - doCleanShutdown is separated in shutdown.py - shared queues are separated in queues.py - some default values were moved to defaults.py - knownnodes partially moved to knownnodes.py

|

The singleCleaner class is a timer-driven thread that cleans data structures
|
|
to free memory, resends messages when a remote node doesn't respond, and
|
|
sends pong messages to keep connections alive if the network isn't busy.
|
|
It cleans these data structures in memory:
|
|
inventory (moves data to the on-disk sql database)
|
|
inventorySets (clears then reloads data out of sql database)
|
|
|
|
It cleans these tables on the disk:
|
|
inventory (clears expired objects)
|
|
pubkeys (clears pubkeys older than 4 weeks old which we have not used personally)
|
|
knownNodes (clears addresses which have not been online for over 3 days)
|
|
|
|
It resends messages when there has been no response:
|
|
resends getpubkey messages in 5 days (then 10 days, then 20 days, etc...)
|
|
resends msg messages in 5 days (then 10 days, then 20 days, etc...)
