2014-03-27add constant for shared (GUI/core) -par settingsPhilip Kaufmann
- introduce DEFAULT_SCRIPTCHECK_THREADS in main.h - only show values from -"MAX_HW_THREADS" up to 16 for -par, as it makes no sense to try to leave more "cores free" than the system supports anyway - use the new constant in optionsdialog and remove defaults from .ui file

2014-03-10Make mining fee policy match relay fee policy.Mike Hearn
This resolves a case in which a mismatch could be used to bloat up the mempool by sending transactions that pay enough fee to relay, but not to be mined, with the default policies.

2014-02-14Handle "conflicted" transactions properlyGavin Andresen
Extend CMerkleTx::GetDepthInMainChain with the concept of a "conflicted" transaction-- a transaction generated by the wallet that is not in the main chain or in the mempool, and, therefore, will likely never be confirmed. GetDepthInMainChain() now returns -1 for conflicted transactions (0 for unconfirmed-but-in-the-mempool, and >1 for confirmed). This makes getbalance, getbalance '*', and listunspent all agree when there are mutated transactions in the wallet. Before: listunspent: one 49BTC output getbalance: 96 BTC (change counted twice) getbalance '*': 46 BTC (spends counted twice) After: all agree, 49 BTC available to spend.

2014-02-08Per-peer block download tracking and stalled download detection.Pieter Wuille
Keep track of which block is being requested (and to be requested) from each peer, and limit the number of blocks in-flight per peer. In addition, detect stalled downloads, and disconnect if they persist for too long. This means blocks are never requested twice, and should eliminate duplicate downloads during synchronization.
2014-01-31Limit the number of orphan blocksPieter Wuille
In case the total number of orphan blocks in memory exceeds a limit (currently set to 750), a random orphan block (which is not depended on by another orphan block) is dropped. This means it will need to be downloaded again, but it won't consume memory until then.

2014-01-27Prepare block connection logic for headers-first.Pieter Wuille
This changes the block processing logic from "try to atomically switch to a new block" to a continuous "(dis)connect a block, aiming for the assumed best chain". This means the smallest atomic operations on the chainstate become individual block connections or disconnections, instead of entire reorganizations. It may mean that we try to reorganize to one block, fail, and rereorganize again to the old block. This is slower, but doesn't require unbounded RAM. It also means that a ConnectBlock which fails may be no longer called from the ProcessBlock which knows which node sent it. To deal with that, a mapBlockSource is kept, and invalid blocks cause asynchronous "reject" messages and banning (if necessary).

After discussing with BlueMatt, this appears to be harmless in its current state since it's always set before it's used. Initialize it anyway for readability and future safety.

Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

2013-11-01Do not use the redundant BestInvalidWork record in the block database.Pieter Wuille
As block index entries have a flag for marking invalid blocks, the 'best invalid work' information can be derived from there. In addition, remove the global from main.h

As CBlockLocator is a P2P data structure, and independent from the validation logic, it can be moved to core.
2013-10-15Reimplement CBlockLocator's chain-related logic in CChain.Pieter Wuille
This removes a few unused CBlockLocator methods, and moves the construction and fork-finding logic to CChain (which can do these more efficiently, as it has a height-indexable chain available). It also makes CBlockLocator independent from the validation code.

2013-08-28[raw] reject insanely high fees by default in sendrawtransactionGregory Maxwell
There have been several incidents where mainnet experimentation with raw transactions resulted in insane fees. This is hard to prevent in the raw transaction api because the inputs may not be known. Since sending doesn't work if the inputs aren't known, we can catch it there. This rejects fees > than 10000 * nMinRelayTxFee or 1 BTC with the defaults and can be overridden with a bool at the rpc.

2013-08-02Simplify storage of orphan transactionsGavin Andresen
Orphan transactions were stored as a CDataStream pointer; this changes the mapOrphanTransactions data structures to store orphans as a CTransaction. This also fixes CVE-2013-4627 by always re-serializing transactions before relaying them.
