Asyncore fixes
- fix broken loops
- optimise I/O tests

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)

Migrate antiIntersectionDelay to asyncore
- 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

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

Add ratings to peers
- outbound peers now have a rating
- it's also shown in the network status tab
- currently it's between -1 to +1, changes by 0.1 steps and uses a
hyperbolic function 0.05/(1.0 - rating) to convert rating to
probability with which we should connect to that node when randomly
chosen
- it increases when we successfully establish a full outbound connection
to a node, and decreases when we fail to do that
- onion nodes have priority when using SOCKS

AddrThread
- this thread is for spreading new/updated addresses in active
connections, analogous to the InvThread
- it doesn't do anything yet, this is just a dummy queue at the moment

Treat some invalid objects as received
- update to 6044df5adf
- objects that are expired or in wrong stream are not re-requested
anymore, even if they aren't stored in the inventory
- the previous option "acceptmismatch" now only affects whether such
objects are stored in the inventory
2017-06-03 16:29:21 +02:00
6044df5adf
Optional storing of expired and off-stream objects
- a new config file option, network/acceptmismatch, allows the inventory
to store objects that expired or are from a stream we're not
interested in. Having this on will prevent re-requesting objects that
other nodes incorrectly advertise. It defaults to false
