sami7777	150828b806	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<CBlock> - 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	2026-05-08 21:34:24 -07:00
sami7777	55c202516d	WIP: migrate ECDSA/ECDH off OpenSSL EC to libsecp256k1 ... Add libsecp256k1 v0.7.1 as src/secp256k1 submodule and introduce crypto_ecdsa / crypto_ecdh wrappers as drop-in replacements for the OpenSSL ECDSA_verify / ECDSA_sign / ECDH_compute_key call sites used by key.cpp and smessage.cpp. Wrappers preserve on-chain compatibility (lax DER parsing, 65-byte recoverable compact sigs, SEC1 priv-key DER round-trip, raw-X ECDH output for smsg KDF). CMake wires the submodule and new sources into the build. Mid-refactor; landing as a checkpoint before stacking sync-pipeline work on top.
