From 88faec75fe768a5702c3f8d9384c0913e4af22aa Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Sat, 17 Sep 2016 15:45:51 +0100 Subject: wallet: select part of the fake outs from recent outputs 25% of the outputs are selected from the last 5 days (if possible), in order to avoid the common case of sending recently received outputs again. 25% and 5 days are subject to review later, since it's just a wallet level change. --- src/cryptonote_core/blockchain.cpp | 4 ++-- src/cryptonote_core/blockchain.h | 3 ++- 2 files changed, 4 insertions(+), 3 deletions(-) (limited to 'src/cryptonote_core') diff --git a/src/cryptonote_core/blockchain.cpp b/src/cryptonote_core/blockchain.cpp index 9d2bf9332..9ea023a4c 100644 --- a/src/cryptonote_core/blockchain.cpp +++ b/src/cryptonote_core/blockchain.cpp @@ -3757,9 +3757,9 @@ bool Blockchain::get_hard_fork_voting_info(uint8_t version, uint32_t &window, ui return m_hardfork->get_voting_info(version, window, votes, threshold, earliest_height, voting); } -std::map Blockchain:: get_output_histogram(const std::vector &amounts, bool unlocked) const +std::map> Blockchain:: get_output_histogram(const std::vector &amounts, bool unlocked, uint64_t recent_cutoff) const { - return m_db->get_output_histogram(amounts, unlocked); + return m_db->get_output_histogram(amounts, unlocked, recent_cutoff); } #if defined(PER_BLOCK_CHECKPOINT) diff --git a/src/cryptonote_core/blockchain.h b/src/cryptonote_core/blockchain.h index 94701608e..262c2952b 100644 --- a/src/cryptonote_core/blockchain.h +++ b/src/cryptonote_core/blockchain.h @@ -729,10 +729,11 @@ namespace cryptonote * * @param amounts optional set of amounts to lookup * @param unlocked whether to restrict instances to unlocked ones + * @param recent_cutoff timestamp to consider outputs as recent * * @return a set of amount/instances */ - std::map get_output_histogram(const std::vector &amounts, bool unlocked) const; + std::map> get_output_histogram(const std::vector &amounts, bool unlocked, uint64_t recent_cutoff) const; /** * @brief perform a check on all key images in the blockchain -- cgit v1.2.3
