24a5c05546 Payment channels: allow usage of unconfirmed coins for building a contract, as the risk is low (they're micropayments anyway). 2013-09-05 15:16:58 +02:00

e05abe150b Wallet: when "emptying" the wallet, only actually empty out the coins that would be considered selectable by the default coin selector. 
By default that means unconfirmed coins won't be emptied, to avoid the empty tx becoming dependent on a tx that may never confirm.

 Resolves issue 438.

33f48d3e22 PeerGroup/Wallet: give the wallet a reference to a transaction broadcaster, so it can make its own transactions and broadcast them outside the context of a user initiated spend. 
Later, we can change the mechanism used to broadcast pending transactions so the wallet does that itself.

630b36c5c8 Payment channels: tweaks to channel resume behaviour. 
Don't create a new channel automatically when the client wants to resume but there's already an open connection using that contract. Instead, disconnect the other client. This fixes unintuitive behaviour that could occur if a TCP connection silently died and the server didn't notice.

2a635317c3 WalletAppKit: Configure the peergroup with candidate peers before adding wallet extensions, as payment channel state can attempt to broadcast a transaction as soon as the state is loaded/instantiated.

c3fd83e511 Add support classes for hierarchical deterministic wallets (BIP 32) 
Code from Matija Mazi. HD wallets allow you to derive keys from a single
root key, giving various useful features:

- Make a backup once and it's good forever (for your keys only of course)
- You can break off parts of the tree and give it to other people,
  they can then generate new keys to send you money without any
  involvement by you (better privacy+security for watching wallets)
- You can delegate sub-trees to other people as a form of access control.

6b7d653614 Major rework of how confidence listeners are called: 
* API change: TransactionConfidence.Listener now takes a reason enum describing the general class of change.
* Confidence listeners are now invoked in the user code thread as well, thus eliminating any chance of unexpected re-entrancy.
* The wallet batches up confidence changes and executes them all at the end of major operations, avoiding confusing intermediate transitions that could occur in the previous design.
* Much code has been simplified as a result and it's now harder to screw up.

5de80dfedf Introduce a user code thread which is used for running event listeners. 
This ensures that when user provided event listeners are invoked, we're not holding any locks at that time and thus event listeners can do whatever they want with no risk of accidental inversions or deadlocks. A utility method is available to wait for all preceding events that were triggered to complete, which is useful for unit tests. Reimplement how balance futures work in order to avoid the wallet registering an event handler on itself, this means you cannot accidentally deadlock yourself by running getBalanceFuture().get() inside an event listener.

Future changes will modify how transaction confidence listeners are run to work the same way, and make other kinds of event listener run in the user code thread as well.

The user code mechanism is usable with any executor, opening up the possibility of automatically relaying event listeners into GUI threads for some kinds of apps.

Matt Corallo
4908c241f7 Implement server-side and client-side payment channel protocols. 
This implements micropayment payment channels in several parts:
 * Adds PaymentChannel[Server|Client]State state machines which
   handle initialization of the payment channel, keep track of
   basic in-memory state, and check data received from the other
   side, based on Mike Hearn's initial implementation.
 * StoredPaymentChannel[Client|Server]States manage channel
   timeout+broadcasting of relevant transactions at that time,
   keeping track of state objects which allow for channel
   resume, and are saved/loaded as a WalletExtension.
 * Adds PaymentChannel[Client|Server] which manage a connection
   by getting new protobufs, generating protobufs for the other
   side, properly stepping the associated State object and
   ensuring the StoredStates object is properly used to save
   state in the wallet.
 * Adds PaymentChannel[ClientConnection|ServerListener] which
   create TCP sockets to each other and use
   PaymentChannel[Client|Server] objects to create/use payment
   channels.

The algorithm implemented is the one described at
https://en.bitcoin.it/wiki/Contracts#Example_7:_Rapidly-adjusted_.28micro.29payments_to_a_pre-determined_party
with a slight tweak to use looser SIGHASH flags so that the
Wallet.completeTx code can work its magic by adding more inputs if
it saves on fees.

Thanks to Mike Hearn for the initial state machine implementations
and all his contracts work and Jeremy Spilman for suggesting the
protocol modification that works with non-standard nLockTime
Transactions.

3d74934b6f Add a length-prefixed protobuf connection server/client. 
This forms the base for payment channel network connections, with
a simple single-threaded server which accepts new connections, a
simple single-threaded client which makes a single connection to a
server, and a ProtobufParser which handles data generated by a
connection, splits them into Protobufs and provides a reasonable
interface to users who wish to create/accept protobuf-based
connections.
