From 45e419bd5c756337635feccec388efedf04f44ac Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Tue, 22 May 2018 14:46:30 +0100 Subject: db: store cumulative rct output distribution in the db for speed This gets rid of the temporary precalc cache. Also make the RPC able to send data back in binary or JSON, since there can be a lot of data This bumps the LMDB database format to v3, with migration. --- src/blockchain_db/blockchain_db.cpp | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) (limited to 'src/blockchain_db/blockchain_db.cpp') diff --git a/src/blockchain_db/blockchain_db.cpp b/src/blockchain_db/blockchain_db.cpp index 88ac34255..8544cc3f0 100644 --- a/src/blockchain_db/blockchain_db.cpp +++ b/src/blockchain_db/blockchain_db.cpp @@ -218,13 +218,22 @@ uint64_t BlockchainDB::add_block( const block& blk // call out to add the transactions time1 = epee::misc_utils::get_tick_count(); + + uint64_t num_rct_outs = 0; add_transaction(blk_hash, blk.miner_tx); + if (blk.miner_tx.version == 2) + num_rct_outs += blk.miner_tx.vout.size(); int tx_i = 0; crypto::hash tx_hash = crypto::null_hash; for (const transaction& tx : txs) { tx_hash = blk.tx_hashes[tx_i]; add_transaction(blk_hash, tx, &tx_hash); + for (const auto &vout: tx.vout) + { + if (vout.amount == 0) + ++num_rct_outs; + } ++tx_i; } TIME_MEASURE_FINISH(time1); @@ -232,7 +241,7 @@ uint64_t BlockchainDB::add_block( const block& blk // call out to subclass implementation to add the block & metadata time1 = epee::misc_utils::get_tick_count(); - add_block(blk, block_size, cumulative_difficulty, coins_generated, blk_hash); + add_block(blk, block_size, cumulative_difficulty, coins_generated, num_rct_outs, blk_hash); TIME_MEASURE_FINISH(time1); time_add_block1 += time1; -- cgit v1.2.3
