From 275894cdefeb80095b4b3463ec732c6e728f91b9 Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Sun, 9 Aug 2015 18:07:44 +0100 Subject: blockchain: always select random outs using triangular distribution It was only used by the older blockchain_storage. We also move the code to the calling blockchain level, to avoid replicating the code in every DB implementation. This also makes the get_random_out method obsolete, and we delete it. --- src/blockchain_db/lmdb/db_lmdb.cpp | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'src/blockchain_db/lmdb/db_lmdb.cpp') diff --git a/src/blockchain_db/lmdb/db_lmdb.cpp b/src/blockchain_db/lmdb/db_lmdb.cpp index dd829f3b0..d231322f6 100644 --- a/src/blockchain_db/lmdb/db_lmdb.cpp +++ b/src/blockchain_db/lmdb/db_lmdb.cpp @@ -1620,19 +1620,6 @@ uint64_t BlockchainLMDB::get_tx_block_height(const crypto::hash& h) const return *(const uint64_t*)result.mv_data; } -//FIXME: make sure the random method used here is appropriate -uint64_t BlockchainLMDB::get_random_output(const uint64_t& amount) const -{ - LOG_PRINT_L3("BlockchainLMDB::" << __func__); - check_open(); - - uint64_t num_outputs = get_num_outputs(amount); - if (num_outputs == 0) - throw1(OUTPUT_DNE("Attempting to get a random output for an amount, but none exist")); - - return crypto::rand() % num_outputs; -} - uint64_t BlockchainLMDB::get_num_outputs(const uint64_t& amount) const { LOG_PRINT_L3("BlockchainLMDB::" << __func__); -- cgit v1.2.3
