| * | | Eliminate unnecessary call to CheckBlockSuhas Daftuar2016-02-011-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ProcessNewBlock would return failure early if CheckBlock failed, before calling AcceptBlock. AcceptBlock also calls CheckBlock, and upon failure would update mapBlockIndex to indicate that a block was failed. By returning early in ProcessNewBlock, we were not marking blocks that fail a check in CheckBlock as permanently failed, and thus would continue to re-request and reprocess them.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also renames whitelistalwaysrelay. Nodes relay all transactions from whitelisted peers, this gets in the way of some useful reasons for whitelisting peers-- for example, bypassing bandwidth limitations. The purpose of this forced relaying is for specialized gateway applications where a node is being used as a P2P connection filter and multiplexer, but where you don't want it getting in the way of (re-)broadcast. This change makes it configurable with whitelistforcerelay.

| * | | | Save the last unnecessary database readAlex Morcos2015-11-181-10/+2
| | | | | | | | | | | | | | | | | | | | It's possible coins with the same hash exist when you create a duplicate coinbase, so previously we were reading from the database to make sure we had the old coins cached so if we were to spend the new ones, the old ones would also be spent. This pull instead just marks the new coins as not fresh if they are from a coinbase, so if they are spent they will be written all the way down to the database anyway overwriting any duplicates.

Max tip age was introduced in #5987 to make it possible to run testnet-in-a-box. But associating this behavior with the testnet chain is wrong conceptually, as it is not needed in normal usage. Should aim to make testnet test the software as-is. Replace it with a (debug) option `-maxtipage`, which can be specified only in the specific case.

This value was zero for all small transactions. For larger transactions (between DEFAULT_BLOCK_PRIORITY_SIZE and MAX_STANDARD_TX_SIZE), this function was preventing low fee transactions from ever being accepted. With this function removed, we will now allow transactions in that range with fees (including modifications via PrioritiseTransaction) below the minRelayTxFee, provided that they have sufficient priority.

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.

This is 25% more space efficient than the previous implementation, and can (at peak) store 1.5 times the requested amount of history (though only 1.0 times the requested history is guaranteed). The existing unit tests should be sufficient.
