* [chain]
- Add basic chain cfg parameters
- Added logic to insert genesis block, if it is a fresh database
- changed SaveBlock to ProcessBlock
- changed SaveHeaders to ProcessHeaders
- Changed parameter from a wire message to the payload, for header and
block processing
- Added check in chain for when the block is in the future, i.e. not at
the tip of the chain
- Added custom error returns, to distinguish between a database error
and a validation error
[Peer]
- Closes#239
- moved response handlers to their own functions
- removed DefaultConfig from LocalConfig file
- passed peer as a parameter to all response handlers
- added peer start height
- refactored NewPeer function to be more concise and clear
- removed empty lines at end of functions
- Added AddMessage/RemoveMessage for Detector in outgoing and ingoing
requests for Block and Headers
* [database]
- Add Prefix method to interface
- Convert leveldb error to `database error`
- Be explicit with prefixedKey in `Table` as slices can be pointers
* [protocol]
- Add stringer method to protocol
* [Chaindb]
- Added saveBlock() which will allow us to save a block into the
database. The block is broken up into transactions and Headers. The
headers are saved as is. The transactions are saved as is, then the
utxos in the transactions are collected to make the utxo db.
- Verification for blocks and transactions will reside in the same
package. Note that the save methods are all unexported, while the Get
methods are exported. Making it so that any can call a get method, but
only code in this package may save to the database. The other code which
will reside in this package will be code verification logic.
* [chaindb]
- Added saveHeader function which saveHeaders uses
- Update the latest header, each time we save a header instead of after a batch. This is so that we can call saveHeader without saveHeaders. This functionality can be rolled back if the performance of updating the header after a batch is significant
- small refactor in test code
* Added new config attributes: 'SecondsPerBlock','LowPriorityThreshold'
* Added new files:
* Added new method: CompareTo
* Fixed empty Slice case
* Added new methods: LessThan, GreaterThan, Equal, CompareTo
* Added new method: InputIntersection
* Added MaxTransactionSize, GroupOutputByAssetID
* Added ned method: ScriptHash
* Added new method: IsDoubleSpend
* Refactor blockchainer, Added Feer interface, Verify and GetMemPool method
* 1) Added MemPool
2) Added new methods to satisfy the blockchainer interface: IsLowPriority, Verify, GetMemPool
* Added new methods: RelayTxn, RelayDirectly
* Fixed tests
* Implemented RPC server method sendrawtransaction
* Refactor getrawtransaction, sendrawtransaction in separate methods
* Moved 'secondsPerBlock' to config file
* Implemented Kim suggestions:
1) Fixed data race issues
2) refactor Verify method
3) Get rid of unused InputIntersection method due to refactoring Verify method
4) Fixed bug in https://github.com/CityOfZion/neo-go/pull/174#discussion_r264108135
5) minor simplications of the code
* Fixed minor issues related to
1) space
2) getter methods do not need pointer on the receiver
3) error message
4) refactoring CompareTo method in uint256.go
* Fixed small issues
* Use sync.RWMutex instead of sync.Mutex
* Refined (R)Lock/(R)Unlock
* return error instead of bool in Verify methods
