From 802c4bb0e4e7a94c07e5c06a3e993e104b529e52 Mon Sep 17 00:00:00 2001 From: SChernykh Date: Thu, 22 Sep 2022 13:06:39 +0200 Subject: [PATCH] Move update_checkpoints() to a later stage update_checkpoints() makes a few DNS requests and can take up to 20-30 seconds to complete (3-6 seconds on average). It is currently called from core::handle_incoming_block() which holds m_incoming_tx_lock, so it blocks all incoming transactions and blocks processing while update_checkpoints() is running. This PR moves it to until after a new block has been processed and relayed, to avoid full monerod locking. --- src/cryptonote_core/cryptonote_core.cpp | 4 ---- src/cryptonote_protocol/cryptonote_protocol_handler.inl | 8 ++++++++ tests/core_proxy/core_proxy.h | 1 + tests/unit_tests/node_server.cpp | 1 + 4 files changed, 10 insertions(+), 4 deletions(-) diff --git a/src/cryptonote_core/cryptonote_core.cpp b/src/cryptonote_core/cryptonote_core.cpp index 31e4e0414..545831199 100644 --- a/src/cryptonote_core/cryptonote_core.cpp +++ b/src/cryptonote_core/cryptonote_core.cpp @@ -1656,10 +1656,6 @@ namespace cryptonote if (((size_t)-1) <= 0xffffffff && block_blob.size() >= 0x3fffffff) MWARNING("This block's size is " << block_blob.size() << ", closing on the 32 bit limit"); - // load json & DNS checkpoints every 10min/hour respectively, - // and verify them with respect to what blocks we already have - CHECK_AND_ASSERT_MES(update_checkpoints(), false, "One or more checkpoints loaded from json or dns conflicted with existing checkpoints."); - block lb; if (!b) { diff --git a/src/cryptonote_protocol/cryptonote_protocol_handler.inl b/src/cryptonote_protocol/cryptonote_protocol_handler.inl index af3031263..bd2f8ce85 100644 --- a/src/cryptonote_protocol/cryptonote_protocol_handler.inl +++ b/src/cryptonote_protocol/cryptonote_protocol_handler.inl @@ -537,6 +537,10 @@ namespace cryptonote MLOG_PEER_STATE("requesting chain"); } + // load json & DNS checkpoints every 10min/hour respectively, + // and verify them with respect to what blocks we already have + CHECK_AND_ASSERT_MES(m_core.update_checkpoints(), 1, "One or more checkpoints loaded from json or dns conflicted with existing checkpoints."); + return 1; } //------------------------------------------------------------------------------------------------------------------------ @@ -819,6 +823,10 @@ namespace cryptonote post_notify(r, context); MLOG_PEER_STATE("requesting chain"); } + + // load json & DNS checkpoints every 10min/hour respectively, + // and verify them with respect to what blocks we already have + CHECK_AND_ASSERT_MES(m_core.update_checkpoints(), 1, "One or more checkpoints loaded from json or dns conflicted with existing checkpoints."); } } else diff --git a/tests/core_proxy/core_proxy.h b/tests/core_proxy/core_proxy.h index fe10dde6e..6d0597ad9 100644 --- a/tests/core_proxy/core_proxy.h +++ b/tests/core_proxy/core_proxy.h @@ -90,6 +90,7 @@ namespace tests bool get_test_drop_download_height() {return true;} bool prepare_handle_incoming_blocks(const std::vector &blocks_entry, std::vector &blocks) { return true; } bool cleanup_handle_incoming_blocks(bool force_sync = false) { return true; } + bool update_checkpoints(const bool skip_dns = false) { return true; } uint64_t get_target_blockchain_height() const { return 1; } size_t get_block_sync_size(uint64_t height) const { return BLOCKS_SYNCHRONIZING_DEFAULT_COUNT; } virtual void on_transactions_relayed(epee::span tx_blobs, cryptonote::relay_method tx_relay) {} diff --git a/tests/unit_tests/node_server.cpp b/tests/unit_tests/node_server.cpp index 6c8cd9f8d..584f98f7a 100644 --- a/tests/unit_tests/node_server.cpp +++ b/tests/unit_tests/node_server.cpp @@ -72,6 +72,7 @@ public: bool get_test_drop_download_height() const {return true;} bool prepare_handle_incoming_blocks(const std::vector &blocks_entry, std::vector &blocks) { return true; } bool cleanup_handle_incoming_blocks(bool force_sync = false) { return true; } + bool update_checkpoints(const bool skip_dns = false) { return true; } uint64_t get_target_blockchain_height() const { return 1; } size_t get_block_sync_size(uint64_t height) const { return BLOCKS_SYNCHRONIZING_DEFAULT_COUNT; } virtual void on_transactions_relayed(epee::span tx_blobs, cryptonote::relay_method tx_relay) {}
