Fixes a bug in AcceptBlock() in invoking CheckBlock() with incorrect arguments, and restores a call to CheckBlock() from ProcessNewBlock() as belt-and-suspenders. Updates the (overspecified) tests to match behavior.

2017-01-13Introduce assumevalid setting to skip presumed valid scripts.Gregory Maxwell
This disentangles the script validation skipping from checkpoints. A new option is introduced "assumevalid" which specifies a block whos ancestors we assume all have valid scriptsigs and so we do not check them when they are also burried under the best header by two weeks worth of work. Unlike checkpoints this has no influence on consensus unless you set it to a block with an invalid history. Because of this it can be easily be updated without risk of influencing the network consensus. This results in a massive IBD speedup. This approach was independently recommended by Peter Todd and Luke-Jr since POW based signature skipping (see PR#9180) does not have the verifiable properties of a specific hash and may create bad incentives. The downside is that, like checkpoints, the defaults bitrot and older releases will sync slower. On the plus side users can provide their own value here, and if they set it to something crazy all that will happen is more time will be spend validating signatures. Checkblocks and checklevel are also moved to the hidden debug options: Especially now that checkblocks has a low default there is little need to change these settings, and users frequently misunderstand them as influencing security or IBD speed. By hiding them we offset the space added by this new option.

2017-01-12Replace FindLatestBefore used by importmuti with FindEarliestAtLeast.Gregory Maxwell
In spite of the name FindLatestBefore used std::lower_bound to try to find the earliest block with a nTime greater or equal to the the requested value. But lower_bound uses bisection and requires the input to be ordered with respect to the comparison operation. Block times are not well ordered. I don't know what lower_bound is permitted to do when the data is not sufficiently ordered, but it's probably not good. (I could construct an implementation which would infinite loop...) To resolve the issue this commit introduces a maximum-so-far to the block indexes and searches that. For clarity the function is renamed to reflect what it actually does. An issue that remains is that there is no grace period in importmulti: If a address is created at time T and a send is immediately broadcast and included by a miner with a slow clock there may not yet have been any block with at least time T. The normal rescan has a grace period of 7200 seconds, but importmulti does not.

2017-01-10Don't overwrite validation state with corruption checkAlex Morcos
AcceptToMemoryPool has several classes of return false statements. - return state.Invalid or state.DoS directly itself - return false and set fMissingInputs (state is valid) - return false and state is set by failed CheckTransaction - return false and state is set by failed CheckInputs. This commit patches the last case where the state variable was reused for additional calls to CheckInputs to identify witness stripping as cause of validation failure. After this commit, it should be the case that if !fMissingInputs, state is always Invalid if AcceptToMemoryPool returns false.

b50cd7a Fix dangerous condition in ModifyNewCoins. (Alex Morcos)
2017-01-04Add IsCurrentForFeeEstimatationAlex Morcos
Make a more conservative notion of whether the node is caught up to the rest of the network and only count transactions as fee estimation data points if the node is caught up.
2017-01-04Always update fee estimates on new blocks.Alex Morcos
All decisions about whether the transactions are valid data points are made at the time the transaction arrives. Updating on blocks all the time will now cause stale fee estimates to decay quickly when we restart a node.
2017-01-04Remove member variable hadNoDependencies from CTxMemPoolEntryAlex Morcos
Fee estimation can just check its own mapMemPoolTxs to determine the same information. Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.
2017-01-04Don't track transactions at all during IBD.Alex Morcos
This was an oversight, where blocks and mempool tracking were ignored during IBD, but transactions that arrived during IBD but were included in blocks after IBD were not ignored.
2017-01-04Fix dangerous condition in ModifyNewCoins.Alex Morcos
We were marking coins FRESH before being sure they were not overwriting dirty undo data. This condition was never reached in existing code because undo data was always flushed before UpdateCoins was called with new transactions, but could have been exposed in an otherwise safe refactor. Clarify in the comments the assumptions made in ModifyNewCoins. Add ability to undo transactions to UpdateCoins unit test. Thanks to Russ Yanofsky for suggestion on how to make logic clearer and fixing up the ccoins_modify_new test cases.
