From fe170698b1ae252f4d9223fef125e2a1419247cc Mon Sep 17 00:00:00 2001 From: jeffro256 Date: Mon, 16 Dec 2024 15:16:34 -0600 Subject: [PATCH] Blockchain: get height of RingCT fork programmatically Get height of the RingCT fork to start the output distributuon programmatically, instead of using a hardcoded index. If using a hardcoded index, when the hardfork tables are modified, this can cause segmentation faults or horrific privacy issues: https://codeberg.org/wownero/wownero/issues/488#issuecomment-2514880. --- src/cryptonote_core/blockchain.cpp | 13 ++----------- 1 file changed, 2 insertions(+), 11 deletions(-) diff --git a/src/cryptonote_core/blockchain.cpp b/src/cryptonote_core/blockchain.cpp index 13c470172a4..75378ceadc2 100644 --- a/src/cryptonote_core/blockchain.cpp +++ b/src/cryptonote_core/blockchain.cpp @@ -2363,17 +2363,8 @@ void Blockchain::get_output_key_mask_unlocked(const uint64_t& amount, const uint bool Blockchain::get_output_distribution(uint64_t amount, uint64_t from_height, uint64_t to_height, uint64_t &start_height, std::vector &distribution, uint64_t &base) const { // rct outputs don't exist before v4 - if (amount == 0) - { - switch (m_nettype) - { - case STAGENET: start_height = stagenet_hard_forks[3].height; break; - case TESTNET: start_height = testnet_hard_forks[3].height; break; - case MAINNET: start_height = mainnet_hard_forks[3].height; break; - case FAKECHAIN: start_height = 0; break; - default: return false; - } - } + if (amount == 0 && m_nettype != network_type::FAKECHAIN) + start_height = m_hardfork->get_earliest_ideal_height_for_version(HF_VERSION_DYNAMIC_FEE); else start_height = 0; base = 0;
