Implemented a new transaction queue. Transactions with a holes in their
nonce sequence are also not propagated over the network.
N: 0,1,2,5,6,7 = propagate 0..2 -- 5..N is kept in the tx pool
You can now specify `null` as a way of saying "not interested in this
topic, match all". core.Filter assumes the zero'd address to be the
wildcard. JSON rpc assumes empty strings to be wildcards.
During a split parent and grand parent were included in the database but
not in the canonical chain (numbered chain). Added a `merge` function
which finds the common ancestor of the chains and reinserts the missing
blocks.
- follow up locks and fix them
- chainManager: call SetQueued for parentErr future blocks, uncomment TD checks, unskip test
- make ErrIncorrectTD non-fatal to be forgiving to genuine mistaken nodes (temp) but demote them to guard against stuck best peers.
- add purging to bounded nodeCache (config nodeCacheSize)
- use nodeCache when creating blockpool entries and let non-best peers add blocks (performance boost)
- minor error in addError
- reduce idleBestPeerTimeout to 1 minute
- correct status counts and unskip status passing status test
- glogified logging
- queued bool // flag for blockpool to skip TD check
- set to true when future block queued
- in checkTD: skip check if queued
- TODO: add test (insertchain sets future block)
The transaction pool will now some easily be able to pre determine the
validity of a transaction by checking the following:
* Account existst
* gas limit higher than the instrinsic gas
* enough funds to pay upfront costs
* nonce check
Logs are now recorded per transactions instead of tossing them out after
each transaction. This should also fix an issue with
`eth_getFilterLogs` (#629) Also now implemented are the `transactionHash,
blockHash, transactionIndex, logIndex` on logs. Closes#654.
