e20c35bf50 Fix FakeChannelSink so events are put into the queue in the right order (BEFORE running event handlers, not after). 2012-12-06 15:01:40 +01:00

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

8d1591183f Rename TransactionInput get/setSequence -> get/setSequenceNumber. The previous name could be confusing and was inconsistent. Add lots of comments to Transaction.hashForSignature. 2012-11-01 14:06:59 +01:00

548333bc6f Refactor BlockChain to make it more extensible. 
This creates a new AbstractBlockChain abstract class which
BlockChain extends.
It continues to have a createable BlockChain class to avoid
changing the API too much.

946d25548f Remove dead code that was used for appearsIn -> appearsInHashes migration, which pre-dates protobuf wallets. Make a few package-private members fully private. 2012-09-29 16:37:04 +02:00
Mike Hearn
78dedcc9ba Re-organize how transaction confidence listeners end up being called. Ensure WalletEventListener.onTransactionConfidenceChanged is always called for every building transaction after every block. Resolves issue 251. 2012-09-27 18:43:31 +02:00

8162aa0ed1 Use current time as unit test chain genesis block time. Resolves a weird issue where the unit tests suddenly broke as the previous unit test genesis time was equal to testnet genesis time. 2012-09-06 12:37:00 +02:00

fedfe9d0e6 Change the wallet to relay tx confidence events instead of generating them itself, which is a bit cleaner. Centralize state that needs to be rebuilt after a Java deserialization. Resolves issue 235. 2012-08-20 18:30:37 +02:00

20d72d7de4 Use a ScriptChunk class in place of byte[] arrays. 2012-08-20 16:23:11 +02:00

75e04174c4 Introduce a concept of "minimum peers for broadcast" to PeerGroup.broadcastTransaction. This can be used to make sending faster when you are bringing up the network in parallel. It defaults to half the max connections. The idea is to insulate you from slow remote peers somewhat. 2012-08-20 16:00:55 +02:00

fd9eba1697 Change PeerGroup.broadcastTransaction() to wait for propagation. 
It means a send won't be considered completed until it's accepted by the net.
Also is for the case where you receive a transaction (eg, via Bluetooth) and
you want to broadcast it such that you can know it's valid.

Make WalletTool use --peers instead of --peer, a comma separated list of
addresses to use. Remove the crappy sleep after send now we can wait.

Resolves issue 167.

ec096993e6 Test and fix transactions in multiple chains going the other way (appears in side chain first, then best) 2012-07-09 22:02:55 +02:00

038438b394 Fix a bug that could cause inconsistent wallets. 
When a side chain block contains the same transactions as the best chain, we incorrectly inserted into the inactive map, triggering assertion failures. Resolves issue 202.

0739a6f674 Port to the latest BouncyCastle API and switch to the SpongyCastle lightweight API. It has the following benefits: 
- Keeps us up to date with the crypto library
 - Resolves the need for an Android artifact by using a renamed lib
 - Switches to the lightweight API so minimizes our dependencies, which is also required for the native branch to be merged

 Resolves issue 171

7f5c8dc3a8 Set outpoint.fromTx during TransactionInput.connect even in the conflict case. Resolves issue 181. Also introduce a helper for creating double spends and rewrite the test case for this in WalletProtobufSerializer to cover more codepaths. Add a comment noting that in the double spending case the overriding transaction isn't presently being stored in the wallet. 2012-04-15 17:51:31 +02:00

d82f102b4b Introduce a new MemoryPool abstraction and use it for tracking peer confidences. This replaces the previous, less explicit system which had each peer try and track all transactions it'd seen in a per-peer pool. 
This makes experimental usage of weak references and a reference queue to make the MemoryPool only bother tracking transactions that were retained by some other part of the program, ie, because they were relevant to the wallet. This stops the memory usage from bloating due to lots of large transactions flying around the network whilst still letting us intelligently monitor how many peers announced transactions without tight coupling between components.

Note that we still need the cap on the pool size because otherwise you could DoS a bitcoinj based program by sending it lots of fake transactions it found interesting. The DoS potential still exists but is a bit different now.
