b64a3b5d1e Some work on DNS discovery - look up all seeds in parallel, pick 30 results, shuffle them and return. Allow users to specify a timeout. Return after the 30 results are found or we run out of time, whichever is first. Should smooth bumpy startup delays caused by occasional seed breakdowns. 2012-12-07 17:06:53 +01:00

26f63550be Implement calculation of a moving average of ping times. Improve PeerMonitor by making columns sortable. 2012-12-07 14:45:41 +01:00
Mike Hearn
3f89eda933 Fix some bugs that happen in chainless operation. Make Peer.getBestChainHeight() more accurate by taking into account blocks announced after a peer is connected, not just what it announced in the initial version message. 2012-12-07 13:59:37 +01:00
Mike Hearn
5cc9710e1f Have PeerGroup ping peers that support BIP 31 ping/pong responses, by default every 5 seconds. The last time ping is available in Peer.getLastPingTime(). This will shortly be used for ordering peers by responsiveness so we don't try and download from overloaded peers. 2012-12-07 12:47:38 +01:00

f440913c1d Some improvements to the network code: 
- Delete the PeerGroupThread and replace it with a connectToAnyPeer() method. Getting connected to the network is now significantly faster as there is no sleep-wait loop between connections.
- Delete the connectionTimeMillis param to the PeerGroup constructors.
- Expose the PeerGroup c'tor that lets you specify the ClientBootstrap and expose a utility method to make one. This means users can now customize TCP options directly.
- PeerGroup.setMaxConnections() now actually creates or tears down connections to meet the new required number, if the peer group is running.
- Update the PeerMonitor so there's a spinner that lets you add or remove peers. Connecting and version handshaking is very fast now.
- Misc changes and fixes.

fc573d5f1c Add a ping() method to the Peer class. It returns a future that can be used to find out when the pong returns and how slow it was. Temporarily, use this in the PeerMonitor example. Next up: moving pinging into the PeerGroup. 2012-11-02 16:19:13 +01:00

b4215e8b01 Add a few Storage classes which avoid storing unnecessary data. 
Specifically, this adds:
* StoredTransaction, which avoid having to store the entire
  transaction when we only need its inputs+outputs.
* StoredTransactionOutput, which avoids having to store the entire
  parentTransaction just to get the hash and index.
* TransactionOutputChanges, which is used to store two lists of
  StoredTransactionOutputs, one for the created set and one for
  the spent set.
* StoredUndoableBlock, which can store either only
  TransactionOutputChanges or only StoredTransactions so that the
  block can be more easily connected/disconnected at will.
