From 802074cba9f23b2e404c2e542cc696547d0017dd Mon Sep 17 00:00:00 2001 From: gary rong Date: Wed, 3 Jul 2019 16:18:48 +0800 Subject: [PATCH] core: fix chain indexer (#19786) This PR fixes an issue in chain indexer. Currently chain indexer will validate whether the stored data is canonical by comparing section head and canonical hash. But the header of the checkpoint may not exist in the database. We should skip validation for sections below the checkpoint. --- core/chain_indexer.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/core/chain_indexer.go b/core/chain_indexer.go index c82febb54..c0c2c4f7f 100644 --- a/core/chain_indexer.go +++ b/core/chain_indexer.go @@ -418,7 +418,7 @@ func (c *ChainIndexer) processSection(section uint64, lastHead common.Hash) (com // actual canonical chain and rolls back reorged sections if necessary to ensure that stored // sections are all valid func (c *ChainIndexer) verifyLastHead() { - for c.storedSections > 0 { + for c.storedSections > 0 && c.storedSections > c.checkpointSections { if c.SectionHead(c.storedSections-1) == rawdb.ReadCanonicalHash(c.chainDb, c.storedSections*c.sectionSize-1) { return }
