2014-12-15Apply AreSane() checks to the fees from the network.Gregory Maxwell
'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.

2014-09-03Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.Pieter Wuille
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.

Fix a few warnings reported by Coverity. None of these is critical, but making sure that class fields are initialized can avoid heisenbugs.

2014-08-26Split up util.cpp/hWladimir J. van der Laan
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.

2014-06-27Relay double-spends, subject to anti-DOSTom Harding
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.
2014-06-26JSON-RPC method: prioritisetransaction <txid> <priority delta> <priority tx fee>Luke Dashjr
Accepts the transaction into mined blocks at a higher (or lower) priority
2014-06-06estimatefee / estimatepriority RPC methodsGavin Andresen
New RPC methods: return an estimate of the fee (or priority) a transaction needs to be likely to confirm in a given number of blocks. Mike Hearn created the first version of this method for estimating fees. It works as follows: For transactions that took 1 to N (I picked N=25) blocks to confirm, keep N buckets with at most 100 entries in each recording the fees-per-kilobyte paid by those transactions. (separate buckets are kept for transactions that confirmed because they are high-priority) The buckets are filled as blocks are found, and are saved/restored in a new fee_estiamtes.dat file in the data directory. A few variations on Mike's initial scheme: To estimate the fee needed for a transaction to confirm in X buckets, all of the samples in all of the buckets are used and a median of all of the data is used to make the estimate. For example, imagine 25 buckets each containing the full 100 entries. Those 2,500 samples are sorted, and the estimate of the fee needed to confirm in the very next block is the 50'th-highest-fee-entry in that sorted list; the estimate of the fee needed to confirm in the next two blocks is the 150'th-highest-fee-entry, etc. That algorithm has the nice property that estimates of how much fee you need to pay to get confirmed in block N will always be greater than or equal to the estimate for block N+1. It would clearly be wrong to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay 12 uBTC and it will take LONGER". A single block will not contribute more than 10 entries to any one bucket, so a single miner and a large block cannot overwhelm the estimates.
