- snapshotnet.cpp: always re-scan on HasServableSnapshot; auto-dump
from current chain when synced to canonical snapshot height
- net.cpp: EnsureLocalSnapshot() at startup so NODE_SNAPSHOT reaches
outbound peers in the first version message
- CMakeLists.txt: add test_snapshotnet + test_chaindb_runtime targets
- test/snapshotnet_tests.cpp, test/chaindb_runtime_tests.cpp: full
coverage for the SnapshotNet P2P protocol + CRocksTxDB wrapper layer
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).

M1.2 (mechanical):
Convert every CTxDB& parameter and reference across main.{h,cpp},
wallet.{h,cpp}, and smessage.cpp to CTxDBBase&. Local instantiations
like `CTxDB txdb("r");` are deliberately left as concrete LevelDB —
they'll move behind a factory in M1.4 once the parity harness exists.
CTxDB IS-A CTxDBBase, so all existing call sites continue to compile:
a CTxDB instance binds to a CTxDBBase& parameter automatically.
Forward declaration `class CTxDB;` in main.h replaced with
`class CTxDBBase;`.
Parallel work (snapshotnet + version bump to 5.9.4 + checkpoints/init
/protocol/version edits) included so origin/master matches the local
working tree in one push.
NOT YET COMPILE-TESTED: pushed at the user's explicit request before
the build verification step. If CI fails, expected breakage is in
files that include main.h transitively but not txdb-base.h — fix is
to add `#include "txdb-base.h"` (or rely on the existing txdb.h which
pulls it in).
