## Blockchain Reactor
|
|
|
|
- coordinates the pool for syncing
|
|
- coordinates the store for persistence
|
|
- coordinates the playing of blocks towards the app using a sm.BlockExecutor
|
|
- handles switching between fastsync and consensus
|
|
- it is a p2p.BaseReactor
|
|
- starts the pool.Start() and its poolRoutine()
|
|
- registers all the concrete types and interfaces for serialisation
|
|
|
|
### poolRoutine
|
|
|
|
- listens to these channels:
|
|
- pool requests blocks from a specific peer by posting to requestsCh, block reactor then sends
|
|
a &bcBlockRequestMessage for a specific height
|
|
- pool signals timeout of a specific peer by posting to timeoutsCh
|
|
- switchToConsensusTicker to periodically try and switch to consensus
|
|
- trySyncTicker to periodically check if we have fallen behind and then catch-up sync
|
|
- if there aren't any new blocks available on the pool it skips syncing
|
|
- tries to sync the app by taking downloaded blocks from the pool, gives them to the app and stores
|
|
them on disk
|
|
- implements Receive which is called by the switch/peer
|
|
- calls AddBlock on the pool when it receives a new block from a peer
|
|
|
|
## Block Pool
|
|
|
|
- responsible for downloading blocks from peers
|
|
- makeRequestersRoutine()
|
|
- removes timeout peers
|
|
- starts new requesters by calling makeNextRequester()
|
|
- requestRoutine():
|
|
- picks a peer and sends the request, then blocks until:
|
|
- pool is stopped by listening to pool.Quit
|
|
- requester is stopped by listening to Quit
|
|
- request is redone
|
|
- we receive a block
|
|
- gotBlockCh is strange
|
|
|
|
## Block Store
|
|
|
|
- persists blocks to disk
|
