|\ | | | | | | b649e03 Create new BlockPolicyEstimator for fee estimates (Alex Morcos)
| * Create new BlockPolicyEstimator for fee estimatesAlex Morcos2015-05-131-353/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This class groups transactions that have been confirmed in blocks into buckets, based on either their fee or their priority. Then for each bucket, the class calculates what percentage of the transactions were confirmed within various numbers of blocks. It does this by keeping an exponentially decaying moving history for each bucket and confirm block count of the percentage of transactions in that bucket that were confirmed within that number of blocks. -Eliminate txs which didn't have all inputs available at entry from fee/pri calcs -Add dynamic breakpoints and tracking of confirmation delays in mempool transactions -Remove old CMinerPolicyEstimator and CBlockAverage code -New smartfees.py -Pass a flag to the estimation code, using IsInitialBlockDownload as a proxy for when we are still catching up and we shouldn't be counting how many blocks it takes for transactions to be included. -Add a policyestimator unit test

* Keep mempool consistent during block-reorgsGavin Andresen2015-03-261-0/+12
| | | | | | | | | | | | | | | | This fixes a subtle bug involving block re-orgs and non-standard transactions. Start with a block containing a non-standard transaction, and one or more transactions spending it in the memory pool. Then re-org away from that block to another chain that does not contain the non-standard transaction. Result before this fix: the dependent transactions get stuck in the mempool without their parent, putting the mempool in an inconsistent state. Tested with a new unit test.

| * Apply AreSane() checks to the fees from the network.Gregory Maxwell2014-12-151-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'Sane' was already defined by this code as: fee.GetFeePerK() > minRelayFee.GetFeePerK() * 10000 But sanity was only enforced for data loaded from disk. Note that this is a pretty expansive definition of 'sane': A 10 BTC fee is still passes the test if its on a 100kb transaction. This prevents a single insane fee on the network from making us reject our stored fee data at start. We still may reject valid saved fee state if minRelayFee is changed between executions. This also reduces the risk and limits the damage from a cascading failure where one party pays a bunch of insane fees which cases others to pay insane fees.

| * | Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.Pieter Wuille2014-09-031-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | The efficient version of CCoinsViewCache::GetCoins only works for known-to-exist cache entries, requiring a separate HaveCoins call beforehand. This is inefficient as both perform a hashtable lookup. Replace the non-mutable GetCoins with AccessCoins, which returns a potentially-NULL pointer. This also decreases the overloading of GetCoins. Also replace some copying (inefficient) GetCoins calls with equivalent AccessCoins, decreasing the copying.

| * Split up util.cpp/hWladimir J. van der Laan2014-08-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.

* Relay double-spends, subject to anti-DOSTom Harding2014-06-271-1/+0
| | | | | | | | | | | | | | | | | | | | Allows network wallets and other clients to see transactions that respend a prevout already spent in an unconfirmed transaction in this node's mempool. Knowledge of an attempted double-spend is of interest to recipients of the first spend. In some cases, it will allow these recipients to withhold goods or services upon being alerted of a double-spend that deprives them of payment. As before, respends are not added to the mempool. Anti-Denial-of-Service-Attack provisions: - Use a bloom filter to relay only one respend per mempool prevout - Rate-limit respend relays to a default of 100 thousand bytes/minute - Define tx2.IsEquivalentTo(tx1): equality when scriptSigs are not considered - Do not relay these equivalent transactions Remove an unused variable declaration in txmempool.cpp.
