From 0840c2fd7eb28aabcf793c2ec59824fd354a936c Mon Sep 17 00:00:00 2001 From: warptangent Date: Sun, 11 Jan 2015 19:07:27 -0800 Subject: Fix height assertion in Blockchain::handle_alternative_block() It expects the total number of blocks of main chain, not last block id (off-by-one error). This again behaves like the same height assertion done in original implementation in blockchain_storage::handle_alternative_block(). This allows a reorganization to proceed after an alternative block has been added. --- src/cryptonote_core/blockchain.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/cryptonote_core') diff --git a/src/cryptonote_core/blockchain.cpp b/src/cryptonote_core/blockchain.cpp index c052e3944..4fa868abe 100644 --- a/src/cryptonote_core/blockchain.cpp +++ b/src/cryptonote_core/blockchain.cpp @@ -1113,7 +1113,7 @@ bool Blockchain::handle_alternative_block(const block& b, const crypto::hash& id if(alt_chain.size()) { // make sure alt chain doesn't somehow start past the end of the main chain - CHECK_AND_ASSERT_MES(m_db->height() - 1 > alt_chain.front()->second.height, false, "main blockchain wrong height"); + CHECK_AND_ASSERT_MES(m_db->height() > alt_chain.front()->second.height, false, "main blockchain wrong height"); // make sure that the blockchain contains the block that should connect // this alternate chain with it. -- cgit v1.2.3
