21b3c06878 Breaks dependency cycle between Script.<clinit>, Script.<init> and NetworkParamenters.<init>. Resolves issue #549. 
Script.<clinit> depended both on Script.<init> and NetworkParameters.<init> to prepare ScriptChunk cache.

At the same time NetworkParameters.<init> depended on Script.<clinit> by using Script.writeBytes().

The fix frees Script.<clinit> from both the NetworkParameters and Script objects.

This should remove the root cause behind NetworkParameters construction not being thread safe.

7f84603e11 Renamed 'bytes', 'msg' to 'payload' in all Message classes. 
* This is intended to clarify distinction between full message and its payload to match terminology advertised on https://en.bitcoin.it/wiki/Protocol_specification.
* Does not change public API.
* These refactorings were mostly automated and should not introduce bugs. All tests pass.

5726b97f70 HD Wallets: mark the DeterministicKeys as issued, if seen in a Transaction 
If a Transaction contains a DeterministicKey of our
DeterministicKeyChains, then we should mark this key as issued. This can
happen, when we replay/resync the blockchain or when another device uses
one of our keys.

534a1e3a5c HD Wallets: add a threshold for the DeterministicKey lookahead 
DeterministicKeyChain.maybeLookAhead() would pre-generate a new key, for
every issued key, even if it is only one. If we replay the blockchain
and update the issuedKeys counter, maybeLookAhead() would trigger the
regeneration and resending of the bloom filter for every used key.

This patch adds a threshold, where keys are only pre-generated after
more keys are needed than the value of the threshold.

24e41f01c6 Refactorings. 
Make a convenience ECKey.decrypt(KeyParameter) that doesn't require the keycrypter to be manually specified, as often (always?) the key knows it already.

Introduce a KeyBag interface that just contains findKeyBy* methods, then make Wallet implement it and change Transaction.signInputs to use it. Take out the encrypted-key specific stuff here: Transaction now requires unencrypted keys. Create a DecryptingKeyBag class that just forwards calls to Wallet and decrypts the returned keys. This decouples the signing code from Wallet a bit.

Should be all API compatible.

a807994b9a Bump wallet version and add missing check (!) to detect wallets from the future. The absence/incompleteness of this feature had not been noticed before, and it means that old apps will fail to read HD wallets due to the new key enum value rather than a more sensible error (but there's still no chance of an old app accepting an HD wallet, so it should still be safe). 2014-05-29 20:11:15 +02:00

c277dc7e4e Require PeerFilterProviders to expose a lock, and use them to avoid a race that occurs during Bloom filter construction. 
It's possible in some uses to cause the Wallet to create two batches of keys one after the other, but independently such that the second batch of keys is derived (with HDWs) whilst the filter is being recalculated from the first. This in turn could race with filter calculation and cause asserts or miscalculated filters.
