Download optimisation
- new data structure to handle download tracking, uses less CPU

Download optimisations
- don't make empty download requests
- use smaller chunks when they can be spread across multiple
connections

Don't crash download thread if no connections 2017-12-02 00:50:58 +01:00

Distribute downloads more evenly
- also increases expireation of missing objects from 10 minutes to an
hour

- longer cycle

Asyncore performance optimisation
- use bytearray instead of strings for buffers

Change thread names
- not needed to have "Thread" in the name of a thread

Asyncore update
- request downloads in bigger chunks
- don't put whole objects into the receiveDataQueue

Asyncore update
- get rid of per-connection writeQueue/receiveQueue, and instead use
strings and locking
- minor code cleanup
- all state handlers now should set expectBytes
- almost all data processing happens in ReceiveDataThread, and
AsyncoreThread is almost only I/O (plus TLS). AsyncoreThread simply
puts the connection object into the queue when it has some data for
processing
- allow poll, epoll and kqueue handlers. kqueue is untested and
unoptimised, poll and epoll seem to work ok (linux)
- stack depth threshold handler  in decode_payload_content, this is
recursive and I think was causing occasional RuntimeErrors. Fixes #964
- longer asyncore loops, as now data is handled in ReceiveDataThread
- randomise node order when deciding what to download. Should prevent
retries being stuck to the same node
- socks cleanup (socks5 works ok, socks4a untested but should work too)

Download thread updates
- 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

Asyncore updates
- 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
