1. rocksdb::WriteBatch::Handler typeinfo missing on Ubuntu's librocksdb-dev.
Both SecMsgBatchScanner (smessage.cpp) and CRocksBatchScanner
(txdb-rocksdb.cpp) inherited from Handler to scan an active WriteBatch
for pending writes/deletes; that subclass-based scan fails to link
because Ubuntu's package hides the parent's typeinfo. Replaced both
scanners with a parallel std::map<std::string, std::optional<std::string>>
maintained alongside each WriteBatch — Put adds a value entry, Delete
adds a nullopt entry, ScanBatch becomes an O(log n) map lookup. Same
semantics, no Handler dependency.
2. macOS Homebrew's RocksDB 10.x removed the raw DB** overload of
DB::Open; only std::unique_ptr<DB>* remains. txdb-rocksdb.cpp called
the raw form, breaking the macOS build. Added the same SFINAE Open
wrapper used in smessage.cpp (commit 4265343) that picks whichever
overload the linked rocksdb actually has.
3. CSignal<>'s SignalState::slots member collided with Qt's `#define slots`
to empty, stripping the member name in any TU that pulls in <QtCore>
(e.g. moc-generated files that include util_signal.h transitively).
Renamed to slot_map.

The secure-messaging store (smsgDB) used the LevelDB API directly. Mass-
mapped to the equivalent RocksDB types: leveldb::DB/Status/WriteBatch/
Iterator/Slice/ReadOptions/WriteOptions/WriteBatch::Handler -> rocksdb::*.
The RocksDB API surface for our usage is binary-compatible — pure namespace
substitution, no semantic changes. Consumers in rpcsmessage.cpp and
qt/messagemodel.cpp updated to match.
RocksDB now becomes a hard build dependency (was optional behind
BUILD_ROCKSDB). The chain-DB rocksdb backend is consequently always
available; -chaindb=leveldb remains the default until the Phase-4
LevelDB retirement. Removed the BUILD_ROCKSDB cmake option, the
#ifdef BUILD_ROCKSDB guards in txdb*, and the runtime error path
that triggered when the flag was off.
CI updated: librocksdb-dev (Ubuntu), mingw-w64-x86_64-rocksdb (MSYS2),
and rocksdb (Homebrew) added to all build jobs.

Migration from boost to std-library equivalents and removal of unreachable
code paths. Touches infrastructure only — no consensus rule or wallet
serialization changes.
Dead code removed:
- IRC bootstrap (irc.cpp/h, 417 lines): orphan from pre-Tor era, no callers.
- Alert system (alert.cpp/h + sendalert RPC + Qt UI signal, ~500 lines):
retired post-V5 fork; old peers' alert messages now hit the unknown-cmd
default branch, logged + ignored.
- Legacy P2P handlers in main.cpp: "checkpoint" (already a no-op stub since
V5 fork master-key removal), "checkorder"/"reply" (2010-era Receive-by-IP
feature), plus their unused supporting structures (CRequestTracker,
PushRequest overloads, mapRequests/cs_mapRequests, mapReuseKey).
- Unreachable RPCs clearwallettransactions and scanforalltxns (~175 lines):
defined in rpcwallet.cpp but never registered in the dispatch table.
- Stale -alertnotify CLI help text (option was advertised but never wired).
boost::filesystem -> std::filesystem (C++17):
- 30 source files, 5 headers. namespace fs = boost::filesystem swapped to
namespace fs = std::filesystem; boost::filesystem::ifstream/ofstream
replaced with std::ifstream/ofstream (path-aware in C++17);
fs::system_complete -> fs::absolute; boost::filesystem::filesystem_error
-> std::filesystem::filesystem_error.
- Build system: dropped Boost::filesystem from link libs and Boost
components; PCH includes updated.
- Added explicit <filesystem> includes where types were previously
available only transitively (db.h, rpcblockchain.cpp).
boost::thread -> std::thread (12 files):
- sync.h CCriticalSection/CWaitableCriticalSection now alias
std::recursive_mutex/std::mutex. boost::unique_lock and
boost::condition_variable / boost::mutex::scoped_lock swapped to std
equivalents; sync.cpp boost::thread_specific_ptr -> thread_local
std::unique_ptr.
- init.cpp boost::thread_group rewritten as std::vector<std::thread> with
manual join loop. boost::thread::hardware_concurrency ->
std::thread::hardware_concurrency.
- main.cpp/wallet.cpp -blocknotify/-walletnotify shell-out threads now use
std::thread(...).detach() — fixes a latent bug where modern boost::thread
destructor would call std::terminate on the joinable thread.
- util.cpp NewThread now catches std::system_error.
- No interruption_point/interrupt usage anywhere — pure mechanical swap.
boost::chrono / boost::posix_time -> std::chrono (3 of 5 files):
- util.h: MilliSleep, GetTimeMillis, GetTimeMicros rewritten on std::chrono
(system_clock for epoch math, sleep_for for delays).
- snapshotnet.cpp: sleep_for swapped.
- DoS_tests.cpp: timing harness uses steady_clock.
- Skipped: rpcdump.cpp (boost::posix_time::time_input_facet has no clean
std::get_time equivalent) and qt/qtipcserver.cpp (locked to
boost::posix_time by boost::interprocess::message_queue::timed_receive).
Other housekeeping:
- Dropped unnecessary "using namespace boost;" from txdb-leveldb.cpp,
txdb-rocksdb.cpp, walletdb.cpp, db.cpp (verified no unqualified boost
names in those TUs).
- Removed unused extern declaration for clearwallettransactions.
Build fixes for non-unity builds on MinGW64/GCC 15:
- net.cpp: dropped stale #include "irc.h".
- addrman.cpp + main.cpp: explicit <cmath> include for sqrt/pow (was
arriving transitively via boost headers).
- rpcblockchain.cpp + init.cpp: defensive #undef STRICT/ADVISORY/PERMISSIVE
since windows.h macros collide with the Checkpoints:: enum values when
std headers reorder include flow.
- tor_embed_hooks.cpp: triangles_tor_check_interrupted now polls fShutdown
instead of boost::this_thread::interruption_requested (we never used
boost interruption — the hook was always effectively a no-op).
- snapshotnet.cpp: fs::remove error handle uses std::error_code.
- serialize.h: added <ios> for std::ios::badbit/failbit (was relying on
transitive include via boost).
Note: unity builds currently fail on this branch due to std::byte (C++17)
colliding with COM 'byte' typedef from shlobj.h when 'using namespace std;'
from earlier files in the unity slice leaks into util.cpp's parse of
shlobj.h. Build with -DENABLE_UNITY_BUILD=OFF (the default).

Adds CRocksTxDB, the second concrete backend for CTxDBBase. Mirrors
CTxDB (LevelDB) one-for-one with rocksdb:: substitutions: same key
serialization (inherited from CTxDBBase), same active-batch semantics,
same LoadBlockIndex flow including the dbformat v3 chain-trust upgrade.
Build flag BUILD_ROCKSDB defaults OFF, so the existing LevelDB build is
untouched — RocksDB headers are only included when the flag is on, and
the entire .cpp file is wrapped in #ifdef BUILD_ROCKSDB.
Build system:
* Top-level option(BUILD_ROCKSDB ... OFF)
* find_package(RocksDB CONFIG) with pkg-config fallback
* Conditional list(APPEND CORE_SOURCES txdb-rocksdb.cpp)
* Conditional target_link_libraries(... RocksDB::rocksdb)
Data layout: RocksDB lives under <datadir>/rocksdb/, separate from
<datadir>/txleveldb/, so both backends can coexist for migration and
parity testing.
Acknowledged debt: LoadBlockIndex is duplicated between CTxDB and
CRocksTxDB. Will be extracted into CTxDBBase once the iterator and
batch abstractions are proven across both backends (M1.4 or later).
Validated: default-OFF build still compiles cleanly. The BUILD_ROCKSDB=ON
path is NOT compile-validated yet — RocksDB isn't installed on this dev
machine. The code is straight namespace substitution from the working
LevelDB backend; whoever first enables the flag should report any
header/API drift between rocksdb releases.
