From fc7e0fe6c75f5c0015935eb49bde677a53be52be Mon Sep 17 00:00:00 2001 From: gary rong Date: Fri, 29 Nov 2019 21:22:08 +0800 Subject: [PATCH] core, miner: remove PostChainEvents (#19396) This change: - removes the PostChainEvents method on core.BlockChain. - sorts 'removed log' events by block number. - fire the NewChainHead event if we inject a canonical block into the chain even if the entire insertion is not successful. - guarantees correct event ordering in all cases. --- core/blockchain.go | 179 ++++++++++++++++++++-------------------- core/blockchain_test.go | 107 ++++++++++++------------ miner/worker.go | 20 ++--- miner/worker_test.go | 12 ++- 4 files changed, 160 insertions(+), 158 deletions(-) diff --git a/core/blockchain.go b/core/blockchain.go index 73b6ee65d7..ebab7a3ab5 100644 --- a/core/blockchain.go +++ b/core/blockchain.go @@ -1260,16 +1260,16 @@ func (bc *BlockChain) writeKnownBlock(block *types.Block) error { } // WriteBlockWithState writes the block and all associated state to the database. -func (bc *BlockChain) WriteBlockWithState(block *types.Block, receipts []*types.Receipt, state *state.StateDB) (status WriteStatus, err error) { +func (bc *BlockChain) WriteBlockWithState(block *types.Block, receipts []*types.Receipt, logs []*types.Log, state *state.StateDB, emitHeadEvent bool) (status WriteStatus, err error) { bc.chainmu.Lock() defer bc.chainmu.Unlock() - return bc.writeBlockWithState(block, receipts, state) + return bc.writeBlockWithState(block, receipts, logs, state, emitHeadEvent) } // writeBlockWithState writes the block and all associated state to the database, // but is expects the chain mutex to be held. -func (bc *BlockChain) writeBlockWithState(block *types.Block, receipts []*types.Receipt, state *state.StateDB) (status WriteStatus, err error) { +func (bc *BlockChain) writeBlockWithState(block *types.Block, receipts []*types.Receipt, logs []*types.Log, state *state.StateDB, emitHeadEvent bool) (status WriteStatus, err error) { bc.wg.Add(1) defer bc.wg.Done() @@ -1394,6 +1394,23 @@ func (bc *BlockChain) writeBlockWithState(block *types.Block, receipts []*types. bc.insert(block) } bc.futureBlocks.Remove(block.Hash()) + + if status == CanonStatTy { + bc.chainFeed.Send(ChainEvent{Block: block, Hash: block.Hash(), Logs: logs}) + if len(logs) > 0 { + bc.logsFeed.Send(logs) + } + // In theory we should fire a ChainHeadEvent when we inject + // a canonical block, but sometimes we can insert a batch of + // canonicial blocks.
