From 150828b806da0757f2b67b7356affd8b358043d4 Mon Sep 17 00:00:00 2001 From: Sami Ahmed Date: Fri, 8 May 2026 21:34:24 -0700 Subject: [PATCH 01/30] C++20 modernization: nullptr, constexpr, smart pointers, thread safety, enum class - Replace ~320 NULL occurrences with nullptr across 47 files (-184 net lines) - static const -> constexpr for version, coin, utility constants - Collapse 9 PushMessage overloads into 1 variadic template with fold expressions - Convert boost::array -> std::array, boost::type_traits -> std:: equivalents - pwalletMain, pScriptCheckQueue, pScriptCheckThreads -> unique_ptr - mapOrphanBlocks values: raw CBlock* -> unique_ptr - Fix data races: add locks to wallet registration, pindexBest reads, mempool exists - pwalletdbEncryption: raw new/delete -> local unique_ptr, remove exit() calls - PoS reward overflow: CBigNum intermediate for nCoinAge * nRewardCoinYear - memset -> OPENSSL_cleanse for secure zeroing - Fix const-cast UB in SetMerkleBranch - Log silent catch(...) blocks instead of silently swallowing - Enum class: GetMinFeeMode, WalletFeature - std::string_view for 8 utility function parameters - Range-for with structured bindings: 63 iterator loops modernized - std::make_pair -> brace init: 35 sites - Delegating constructors: CWallet, CBlockIndex - Merkle tree caching, std::array for GetMedianTimePast - CScript copy ctor -> = default, operator!= -> = default --- src/addrman.cpp | 31 ++-- src/allocators.h | 8 +- src/bignum.h | 28 ++-- src/bootstrap.cpp | 2 +- src/checkpoints.cpp | 12 +- src/crypter.cpp | 4 +- src/crypto_ecdh.cpp | 2 +- src/db.cpp | 38 ++--- src/db.h | 24 +-- src/init.cpp | 69 ++++----- src/init.h | 3 +- src/key.h | 2 +- src/keystore.cpp | 24 ++- src/keystore.h | 18 +-- src/main.cpp | 309 ++++++++++++++++++------------------- src/main.h | 148 +++++++----------- src/miner.cpp | 13 +- src/net.cpp | 88 +++++------ src/net.h | 145 ++--------------- src/netbase.cpp | 20 +-- src/onionseed.h | 4 +- src/qt/trianglesgui.cpp | 3 +- src/qt/walletmodel.h | 2 +- src/rpcblockchain.cpp | 10 +- src/rpcdump.cpp | 6 +- src/rpcrawtransaction.cpp | 2 +- src/rpcwallet.cpp | 4 +- src/script.cpp | 8 +- src/script.h | 2 +- src/serialize.h | 40 ++--- src/smessage.cpp | 36 ++--- src/smessage.h | 6 +- src/sync.cpp | 6 +- src/sync.h | 6 +- src/tor/onion_v3.cpp | 7 +- src/tor/tor_process.cpp | 28 ++-- src/trianglesrpc.cpp | 24 +-- src/trianglesrpc.h | 2 +- src/txdb-leveldb.cpp | 26 ++-- src/util.cpp | 45 ++++-- src/util.h | 36 +++-- src/utxosnapshot.cpp | 4 +- src/version.h | 22 +-- src/wallet.cpp | 261 ++++++++++++++----------------- src/wallet.h | 54 +++---- src/walletdb.h | 32 ++-- src/zmqpublishnotifier.cpp | 14 +- 47 files changed, 747 insertions(+), 931 deletions(-) diff --git a/src/addrman.cpp b/src/addrman.cpp index e605a91..1fcb9a3 100644 --- a/src/addrman.cpp +++ b/src/addrman.cpp @@ -81,15 +81,14 @@ double CAddrInfo::GetChance(int64_t nNow) const CAddrInfo* CAddrMan::Find(const CNetAddr& addr, int *pnId) { - std::map::iterator it = mapAddr.find(addr);

MaybeMigrateLevelDbToRocksDb() is now reachable via -migratechaindb / -migratechaindbforce in init.cpp. Reads from /txleveldb and writes byte-for-byte identical records into /rocksdb via a new CRocksTxDB::WriteRawRecordForMigration() shim over WriteRaw.
