- implemented by ignoring getdata during the delay rather than sleeping
as it was in the threaded model
- it can happen that a valid getdata request is received during the
delay. A node should be implemented in a way that retries to download,
that may not be the case with older PyBitmessage versions or other
implementations
- now tracks downloads globally too, so it doesn't request the same
object from multiple peers at the same time
- retries at the earliest every minute
- stops trying to download an object after an hour
- minor fixes in retrying downloading invalid objects
- should prevent the same object being re-requested indefinitely
- locking for object tracking
- move SSL-specific error handling to TLSDispatcher
- observe maximum connection limit when accepting a new connection
- stack depth test (for debugging purposes)
- separate download thread
- connection pool init moved to main thread
- asyncore is now on by default
- inv announcements implemented
- bandwidth limit implemented / fixed
- stats on download / upload speed now work
- make prints into logger
- limit knownNodes to 20k as it was before
- green light fixed
- other minor fixes
- bugfixes
- UDP socket for local peer discovery
- new function assembleAddr to unify creating address command
- open port checker functionality (inactive)
- sendBigInv is done in a thread separate from the network IO
thread
- separate queue for processing blocking stuff on reception
- rewrote write buffer as a queue
- some addr handling
- number of half open connections correct
