Adjust SOURCE_DB in src/blockchain_converter/blockchain_export.h depending on needs. Defaults to DB_MEMORY. DB_MEMORY is a sensible default for users migrating to LMDB, as it allows the exporter to use the in-memory blockchain while the other binaries work with LMDB, without recompiling anything. --- .../blockchain_export.cpp | 67 ++++++++++++------- src/blockchain_converter/blockchain_export.h | 31 ++++++--- 2 files changed, 65 insertions(+), 33 deletions(-) diff --git a/src/blockchain_converter/blockchain_export.cpp b/src/blockchain_converter/blockchain_export.cpp index 33944dba6..2467951de 100644 --- a/src/blockchain_converter/blockchain_export.cpp +++ b/src/blockchain_converter/blockchain_export.cpp @@ -45,12 +45,6 @@ #include "cryptonote_core/cryptonote_boost_serialization.h" #include "import.h" -// #include "fake_core.h" - -#define SOURCE_DB DB_MEMORY -// currently not supported: -// to use what was set at compile time (DB_MEMORY or DB_LMDB) -// #define SOURCE_DB BLOCKCHAIN_DB static int max_chunk = 0; static size_t height; @@ -151,21 +145,21 @@ void BlockchainExport::write_block(block& block) // put coinbase transaction first transaction coinbase_tx = block.miner_tx; crypto::hash coinbase_tx_hash = get_transaction_hash(coinbase_tx); - // blockchain_storage: +#if SOURCE_DB == DB_MEMORY const transaction* cb_tx_full = m_blockchain_storage->get_tx(coinbase_tx_hash); - // - // BlockchainDB: - // transaction cb_tx_full = m_blockchain_storage->get_tx(coinbase_tx_hash); +#else + transaction cb_tx_full = m_blockchain_storage->get_db()->get_tx(coinbase_tx_hash); +#endif - - // blockchain_storage: +#if SOURCE_DB == DB_MEMORY if (cb_tx_full != NULL) { txs.push_back(*cb_tx_full); } - // - // BlockchainDB: - // txs.push_back(cb_tx_full); +#else + // TODO: should check and abort if cb_tx_full equals null_hash? + txs.push_back(cb_tx_full); +#endif // now add all regular transactions BOOST_FOREACH(const auto& tx_id, block.tx_hashes) @@ -173,7 +167,7 @@ void BlockchainExport::write_block(block& block) #if SOURCE_DB == DB_MEMORY const transaction* tx = m_blockchain_storage->get_tx(tx_id); #else - transaction tx = m_blockchain_storage->get_tx(tx_id); + transaction tx = m_blockchain_storage->get_db()->get_tx(tx_id); #endif #if SOURCE_DB == DB_MEMORY @@ -208,9 +202,22 @@ void BlockchainExport::write_block(block& block) bool include_extra_block_data = true; if (include_extra_block_data) { +#if SOURCE_DB == DB_MEMORY size_t block_size = m_blockchain_storage->get_block_size(block_height); +#else + size_t block_size = m_blockchain_storage->get_db()->get_block_size(block_height); +#endif +#if SOURCE_DB == DB_MEMORY difficulty_type cumulative_difficulty = m_blockchain_storage->get_block_cumulative_difficulty(block_height); +#else + difficulty_type cumulative_difficulty = m_blockchain_storage->get_db()->get_block_cumulative_difficulty(block_height); +#endif +#if SOURCE_DB == DB_MEMORY uint64_t coins_generated = m_blockchain_storage->get_block_coins_generated(block_height); +#else + // TODO TEST to verify that this is the equivalent. make sure no off-by-one error with block height vs block number + uint64_t coins_generated = m_blockchain_storage->get_db()->get_block_already_generated_coins(block_height); +#endif *m_raw_archive << block_size; *m_raw_archive << cumulative_difficulty; @@ -234,7 +241,7 @@ bool BlockchainExport::BlockchainExport::close() #if SOURCE_DB == DB_MEMORY bool BlockchainExport::store_blockchain_raw(blockchain_storage* _blockchain_storage, tx_memory_pool* _tx_pool, boost::filesystem::path& output_dir, uint64_t use_block_height) #else -bool BlockchainExport::store_blockchain_raw(BlockchainDB* _blockchain_storage, tx_memory_pool* _tx_pool, boost::filesystem::path& output_dir, uint64_t use_block_height) +bool BlockchainExport::store_blockchain_raw(Blockchain* _blockchain_storage, tx_memory_pool* _tx_pool, boost::filesystem::path& output_dir, uint64_t use_block_height) #endif { uint64_t use_block_height2 = 0; @@ -339,7 +346,7 @@ int main(int argc, char* argv[]) m_config_folder = command_line::get_arg(vm, data_dir_arg); boost::filesystem::path output_dir {m_config_folder}; output_dir /= "export"; - std::cout << "config directory: " << m_config_folder << ENDL; + LOG_PRINT_L0("Export directory: " << output_dir.string()); // If we wanted to use the memory pool, we would set up a fake_core. @@ -349,13 +356,25 @@ int main(int argc, char* argv[]) // core_storage = new blockchain_storage(&m_mempool); blockchain_storage* core_storage = new blockchain_storage(NULL); -#else - BlockchainDB* core_storage = new BlockchainLMDB(); -#endif - // tx_memory_pool m_mempool(core_storage); - - LOG_PRINT_L0("Initializing source blockchain storage..."); + LOG_PRINT_L0("Initializing source blockchain (in-memory database)"); r = core_storage->init(m_config_folder, opt_testnet); +#else + // Use Blockchain instead of lower-level BlockchainDB for two reasons: + // 1.
