dece35e95c Fix typo in name of FilteredBlockAndPartialMerkleTreeTests 2013-01-28 16:32:32 +01:00

35d6084bbf Refactor some of the wallet/peer interaction. Analyze dependencies of relevant pending transactions. 
The Peer object now asks each connected Wallet if it cares about a transaction. If it does, then receivePending() is not called immediately, but rather after downloading of dependencies and with those dependencies. If any dependencies are time locked, a new wallet property controls whether they are discarded or not.

e9babb2772 Use ping messages to work around the lack of notfound messages on old nodes. 
For now optimistically assume Gavin merges the notfound patch into bitcoin-qt, version wise.

b7b52c3fc9 Add support for recursively downloading mempool dependencies of a given mempool transaction. 
This isn't currently used anywhere, but can be used as the first step of doing some basic risk analysis of unconfirmed transactions.

a5f9c3381b Add relayTxesBeforeFilter flag to VersionMessage, PROTOCOL_VERSION 
This adds a relayTxesBeforeFilter flag to VersionMessage, bringing

PROTOCOL_VERSION accordingly.

916e33254f Resolve some race conditions. 
It was possible that during saving of a wallet a network thread would update the confidence metrics due to broadcast announcements. This change makes TransactionConfidence use a COW list so the broadcast peer set can be iterated over safely. Resolves issue 277.

b5b43f3a15 Better support for lock timed transactions. 
Lock times are now included in various toString dumps.
Transactions can estimate their lock time when the time is specified as a block number.
Add support to WalletTool for creating timelocked transactions.

ae6b2fbd4d Improvements to the ECKey class: 
- Implement ECDSA key recovery.
- Use it to implement sign/verifymessage functionality that's compatible with Bitcoin-Qt.
- Redesign the signing APIs a bit.

7e8ed913ec Use ChannelGroups for shutdowns. This cleans up the code and makes the PeerGroup shutdown futures work correctly. 2013-01-04 18:29:47 +01:00

0208b426f5 Add a few more tests to FullBlockTestGenerator. 
...including one which (somewhat) tests the optimally encoded size
stuff.

671a5aec18 Add a TransactionInput.verify() method that checks signatures and use it from the basicSpending test to ensure we generate valid signatures/scripts. 2012-12-26 18:14:39 +00:00

07011be796 Introduce a PeerGroup method for calculating the most common chain height. 
Use it to make peer selection a little smarter.
Render pending peers and peers that are reporting un-common chain heights in PeerMonitor.

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

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

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

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.
