* Added
1) ReverseString method to the Uint160 type
2) ToReverseScriptHash method to convert a base58 address to a reverse script hash
* Simplified ToScriptHash method
- refactored OnBlockBlockMode to use blockPool
- syncmgr now checks for future blocks, instead of looking for a
FutureBlockErr from the Chain. This makes it so that syncmgr does not
depend on the Chain package.
- removed GetBestBlockHash function from config(unused)
- refactored all tests in the syncmgr package
- refactor syncmgr for blockpool
- add nextBlockIndex so that we can add blocks to the blockPool by
comparing their index
- add processBlock helper method,wraps around cfg.ProcessBlock and increments the nextBlockIndex
internally
[peermgr]
- Add request cache with tests
- Add requestCache to peermgr
- refactored peer manager tests
- Added blockInfo struct, to allow sorting on the blockIndex
- added helper methods for cache, pickItem, pickFirstItem, removeHash,
findHash and refactored tests
- renamed requestcache to blockcache
- refactored peer manager to use block cache for block requests *only*
- added blockCallPeer function to handle block requests only
- refactored onDisconnect to add back any pending peer requests that the
disconnected peer did not complete into the peer manager queue
[peermgr/server]
- Modify onBlock handler in server, to send peermgr a BlockInfo struct
[peermgr/syncmgr/server]
- Modified blockIndex in BlockInfo to be uint32 and not uint64
- RequestBlocks in syncmgr now takes an index along with the hash
- modified syncmgr code to pass index along with hash in all methods
* [syncmgr]
- Add blockmode, normal mode, headermode
- Add config file
- Add test files
- removed RequestBlocks and RequestHeaders from peers, as we will use
the peermanager for this
- OnHeaders and OnBlock in syncmgr, now return errors
- refactored all tests to use a convenience method to return a syncmgr
and testHelper
* [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
