* Rewrite CreateNewBlockAlex Morcos2015-12-011-24/+36
| | | | | | | | | | Use the score index on the mempool to only add sorted txs in order. Remove much of the validation while building the block, relying on mempool to be consistent and only contain txs that can be mined. The mempool is assumed to be consistent as far as not containing txs which spend non-existent outputs or double spends, and scripts are valid. Finality of txs is still checked (except not coinbase maturity, assumed in mempool). Still TestBlockValidity in case mempool consistency breaks and return error state if an invalid block was created. Unit tests are modified to realize that invalid blocks can now be constructed if the mempool breaks its consistency assumptions and also updated to have the right fees, since the cached value is now used for block construction.

* | Switch blocks to a constant-space Merkle root/branch algorithm.Pieter Wuille2015-11-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | This switches the Merkle tree logic for blocks to one that runs in constant (small) space. The old code is moved to tests, and a new test is added that for various combinations of block sizes, transaction positions to compute a branch for, and mutations: * Verifies that the old code and new code agree for the Merkle root. * Verifies that the old code and new code agree for the Merkle branch. * Verifies that the computed Merkle branch is valid. * Verifies that mutations don't change the Merkle root. * Verifies that mutations are correctly detected.

* Enable policy enforcing GetMedianTimePast as the end point of lock-time ↵Mark Friedenbach2015-10-231-3/+4
| | | | | | constraints Transactions are not allowed in the memory pool or selected for inclusion in a block until their lock times exceed chainActive.Tip()->GetMedianTimePast(). However blocks including transactions which are only mature under the old rules are still accepted; this is *not* the soft-fork required to actually rely on the new constraint in production.
* Do not store Merkle branches in the wallet.Pieter Wuille2015-09-221-1/+1
| | | | | | | | | | Assume that when a wallet transaction has a valid block hash and transaction position in it, the transaction is actually there. We're already trusting wallet data in a much more fundamental way anyway. To prevent backward compatibility issues, a new record is used for storing the block locator in the wallet. Old wallets will see a wallet file synchronized up to the genesis block, and rescan automatically.

| | | | | | | | If/when CTransaction::CURRENT_VERSION is incremented, this will break CChainParams and the miner tests. This fix sets the transaction version explicitly where we depend on the hash value (genesis block, proof of work checks).

|\ | | | | | | 28bf062 Fix off-by-one error w/ nLockTime in the wallet (Peter Todd)
| * Fix off-by-one error w/ nLockTime in the walletPeter Todd2015-05-271-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously due to an off-by-one error the wallet ignored nLockTime-by-height transactions that would be valid in the next block even though they are accepted into the mempool. The transactions wouldn't show up until confirmed, nor would they be included in the unconfirmed balance. Similar to the mempool behavior fix in 665bdd3b, the wallet code was calling IsFinalTx() directly without taking into account the fact that doing so tells you if the transaction could have been mined in the *current* block, rather than the next block. To fix this we strip IsFinalTx() of non-consensus-critical functionality, removing the default arguments, and add CheckFinalTx() to check if a transaction will be final in the next block.
