From 343cc4fa433ea476678fdf44e792ebd5077610ee Mon Sep 17 00:00:00 2001 From: Zahary Karadjov Date: Fri, 5 Oct 2018 03:20:12 +0300 Subject: [PATCH] Populate the persistent databases with the empty RLP key. Also implements transactional block persistence. Two issues in the transaction processing code have been discovered that might affect other usages such as the CALL instruction. The main fix gets us past block 49000. You may need to clean up your database. --- nimbus/db/backends/caching_backend.nim | 6 +++-- nimbus/db/backends/rocksdb_backend.nim | 29 +++++++++++---------- nimbus/db/backends/sqlite_backend.nim | 6 ++++- nimbus/db/db_chain.nim | 2 +- nimbus/db/state_db.nim | 2 +- nimbus/genesis.nim | 8 +++--- nimbus/nimbus.nim | 2 +- nimbus/p2p/chain.nim | 12 ++++++--- nimbus/rpc/common.nim | 7 +++--- nimbus/rpc/p2p.nim | 35 ++++++++++++++------------ tests/test_caching_db_backend.nim | 9 ++++--- tests/test_generalstate_json.nim | 2 +- tests/test_opcode.nim | 3 +-- tests/test_vm_json.nim | 3 +-- 14 files changed, 73 insertions(+), 53 deletions(-) diff --git a/nimbus/db/backends/caching_backend.nim b/nimbus/db/backends/caching_backend.nim index cc19ecd8c..92f0d6644 100644 --- a/nimbus/db/backends/caching_backend.nim +++ b/nimbus/db/backends/caching_backend.nim @@ -1,5 +1,7 @@ -import ranges, eth_trie, tables, sets -import ../storage_types +import + ranges, tables, sets, + eth_trie/db, + ../storage_types type CachingDB* = ref object of RootObj diff --git a/nimbus/db/backends/rocksdb_backend.nim b/nimbus/db/backends/rocksdb_backend.nim index 6216bce53..580d09753 100644 --- a/nimbus/db/backends/rocksdb_backend.nim +++ b/nimbus/db/backends/rocksdb_backend.nim @@ -1,4 +1,4 @@ -import os, rocksdb, ranges, eth_trie/db_tracing +import os, rocksdb, ranges, eth_trie/[db_tracing, constants] import ../storage_types type @@ -7,18 +7,6 @@ type ChainDB* = RocksChainDB -proc newChainDB*(basePath: string): ChainDB = -
