2015-12-14Replace trickle nodes with per-node/message Poisson delaysPieter Wuille
We used to have a trickle node, a node which was chosen in each iteration of the send loop that was privileged and allowed to send out queued up non-time critical messages. Since the removal of the fixed sleeps in the network code, this resulted in fast and attackable treatment of such broadcasts. This pull request changes the 3 remaining trickle use cases by random delays: * Local address broadcast (while also removing the the wiping of the seen filter) * Address relay * Inv relay (for transactions; blocks are always relayed immediately) The code is based on older commits by Patrick Strateman.

8f0d79e test: Disable scheduler test manythreads (Wladimir J. van der Laan)
2015-12-01Rewrite CreateNewBlockAlex Morcos
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. Conflicts: src/miner.cpp
2015-12-01Add a score index to the mempool.Alex Morcos
The score index is meant to represent the order of priority for being included in a block for miners. Initially this is set to the transactions modified (by any feeDelta) fee rate. Index improvements and unit tests by sdaftuar.

Store sum of legacy and P2SH sig op counts. This is calculated in AcceptToMemory pool and storing it saves redoing the expensive calculation in block template creation.

2015-11-19Change GetPriority calculation.Alex Morcos
Compute the value of inputs that already are in the chain at time of mempool entry and only increase priority due to aging for those inputs. This effectively changes the CTxMemPoolEntry's GetPriority calculation from an upper bound to a lower bound.
2015-11-27Switch blocks to a constant-space Merkle root/branch algorithm.Pieter Wuille
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.

2015-11-16Increase success threshold for fee estimation to 95%Alex Morcos
This provides more conservative estimates and reacts more quickly to a backlog. Unfortunately the unit test for fee estimation depends on the success threshold (and the decay) chosen; also modify the unit test for the new default success thresholds.

2015-10-27unittest: fix test for null tx inputDaniel Kraft
Update the unittest that is meant to catch a transaction that is invalid because it has a null input. The old test failed not because of that but because it was considered a coinbase with too large script. This is already checked with a different test, though. The new test is *not* a coinbase since it has two inputs, but one of them is null. This really checks the corresponding code path in CheckTransaction.

2015-10-23Enable policy enforcing GetMedianTimePast as the end point of lock-time ↵Mark Friedenbach
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.
