Done, please wait to merge I'm going to push some change |

@sorpaas added functionality to only notify when the node is synced, mostly to mimic what substrate block import notification does. What do you think of https://github.com/paritytech/frontier/pull/1030/files#diff-238ded0693b6a31db32cd68411cd48e079cd87097b3436fe7ef70b222b2eeb25R248-R249? do you think is reasonable to close the channel and remove it from memory when the node is in major syncing? |

We currently use substrate block import notification stream in our pubsub module, that can lead to a race condition if a Dapp subscribes to
newHeadsand quickly after requests for data that requires the mapping in our offchain db to exist (i.e.eth_getBlockByHash). This data may or may not exist at that moment. As in any race condition cannot be reliably reproduced but this behaviour has been reported to exist in Moonbeam several times.This PR proposes to switch to use our own Ethereum block import notification stream, that is,
senda message through a channel when data is already mapped in our offchain db andreceivethrough the channel in the pubsub subscription.
