| * | | | Do not store Merkle branches in the wallet.Pieter Wuille2015-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assume that when a wallet transaction has a valid block hash and transaction position in it, the transaction is actually there. We're already trusting wallet data in a much more fundamental way anyway. To prevent backward compatibility issues, a new record is used for storing the block locator in the wallet. Old wallets will see a wallet file synchronized up to the genesis block, and rescan automatically.

| * | | | | [Trivial] [logging] Rm extraneous cleansubver in serveral debug messages.Gregory Maxwell2015-09-081-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We log the cleanSubVer as part of connect. It is not uniquely more informative than any of the other data we have about a peer, often less. It's also often long now as well. There is no need to output it as part of mempoolrej, AcceptToMemoryPool, or pong entries. Leaving it out makes our log entries more uniform and consistent.

Sort mempool by max(feerate of entry, feerate of descendants). Update statistics on-the-fly as transactions enter or leave the mempool. Also add ancestor and descendant limiting, so that transactions can be rejected if the number or size of unconfirmed ancestors exceeds a target, or if adding a transaction would cause some other mempool entry to have too many (or too large) a set of unconfirmed in- mempool descendants.

The protocol version bump allows SPV nodes to assume that NODE_BLOOM is set if NODE_NETWORK is set for pre-70011 nodes. Also adds an option to turn bloom filter support off for nodes which advertise a version number >= 70011. Nodes attempting to use bloom filters on such protocol versions are banned, and a later upgade should drop nodes of an older version which attempt to use bloom filters. Much code stolen from Peter Todd. Implements BIP 111

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids that premature return in the condition that a new chain is initialized results in NULL pointer errors due to recentReject not being constructed. Also add assertions where it is used.
| * | | | | Keep track of recently rejected transactionsPeter Todd2015-07-281-9/+59

This can cause you to repeatedly request and reject the same tx after its inved to you from various peers which have accepted it. Here we add rolling bloom filter to keep track of such rejections, clearing the filter every time the chain tip changes. Credit goes to Alex Morcos, who created the patch that this code is based on. Original code by Peter Todd. Refactored to not construct the filter at startup time by Pieter Wuille.
| * | | | | Make CRollingBloomFilter set nTweak for youPeter Todd2015-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While CBloomFilter is usually used with an explicitly set nTweak, CRollingBloomFilter is only used internally. Requiring every caller to set nTweak is error-prone and redundant; better to have the class handle that for you with a high-quality randomness source. Additionally when clearing the filter it makes sense to change nTweak as well to recover from a bad setting, e.g. due to insufficient randomness at initialization, so the clear() method is replaced by a reset() method that sets a new, random, nTweak value.
