* Miners do now verify their own header, not their state.
* Changed old putTx and putReceipts to be exported
* Moved writing of transactions and receipts out of the block processer
in to the chain manager. Closes#1386
* Miner post ChainHeadEvent & ChainEvent. Closes#1388
This fixes an issue with the lru cache not being available when calling
WriteBlock. WriteBlock previously always assumed to be called from the
InsertChain where the lru cache was always created prior to calling
WriteBlock. When being called from the worker this could lead in to a
nil pointer exception being thrown and causing database corruption.
Removed the managed tx state from the chain manager to the transaction
pool where it's much easier to keep track of nonces (and manage them).
The transaction pool now also uses the queue and pending txs differently
where queued txs are now moved over to the pending queue (i.e. txs ready
for processing and propagation).
* Miner should no longer generate blocks with a time stamp less or equal
than it's parent.
* Future blocks are no longer processed and queued directly.
Closes#1118
if you track stale blocks, then you quickly overflow your ring buffer in the local network case where you're mining every block and generating a lot of stales.
This helps determine which blocks are unlikely to end up as uncles
* Store the 5 most recent locally mined block numbers
* On every imported block, check if the 5-deep block num is in that store
* Also confirm that the block is signed with miner's coinbase
Why not just check the coinbase? This log is useful if you're running
multiple miners and want to know if *this* miner is performing well.
* core: Added GasPriceChange event
* eth: When one of the DB flush methods error a fatal error log message
is given. Hopefully this will prevent corrupted databases from
occuring.
* miner: remove transactions with low gas price. Closes#906, #903
* Changed CalcGasLimit to no longer need current block
* Added a gas * price + value on tx validation
* Transactions in the pool are now re-validated once every X
When worker encounters a gas limit error, subsequent txs should be
ignored from that particular account. This will prevent:
1. Nonce errors been thrown all around
2. The "Known tx" error. Closes#719
3. Repeated contract address. Closes#731
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.
