WIP: modernization applied to DNS2 tree

Browse Source 
Brings in uncommitted work from SAMI-PC E:\repos\triangles
cpp20-modernization branch:
- RocksDB default chain DB + auto-migrate from txleveldb
- SQLite default wallet + non-destructive migration from Berkeley
- Boost.Asio removed from RPC (rpc_httpsocket.h)
- Boost removed from all daemon + GUI code
- New: walletdb-base.h, walletdb-batch.h, walletdb-sqlite.{h,cpp},
  walletdb-factory.{h,cpp}, walletmigrate.{h,cpp}
- New tests: chaindb_runtime_tests, chaindb_equivalence_tests,
  snapshotnet_tests
- Docs: BOOST-REMOVAL.md, ROCKSDB-DEFAULT-MIGRATION.md,
  WALLET-SQLITE-MIGRATION.md

Does not yet build — needs CWalletDB->CWalletBatchTyped rebase in
walletdb.cpp/wallet.cpp/db.cpp and merge with origin/master for
v6 source files (checkpointpublisher, tor/, snapshot/, utxosnapshot,
bootstrap.cpp).

Build flags: -DBUILD_QT=OFF -DUSE_I2P_EMBEDDED=OFF

# Boost removal — progress
Goal: drop the Boost dependency in favor of C++17 std. No consensus or wire
behavior changes.
## Done
**Triangles' own code (daemon + GUI) is now completely Boost-free.** All nine
translation units that used Boost have been migrated. The only remaining Boost
usage in the tree is (1) the Boost.Test unit-test framework under `src/test/`,
and (2) Boost as a *transitive link dependency of the bundled embedded i2pd
router* (`libi2pd.a`) — not of any Triangles source. See "Remaining" below.
| File | Boost removed | Replacement |
|------|---------------|-------------|
| `txdb-leveldb.cpp` | `boost/version.hpp` (unused include) | deleted |
| `txdb-rocksdb.cpp` | `boost/version.hpp` (unused include) | deleted |
| `walletdb.cpp` | `boost/version.hpp` + `BOOST_VERSION` guard | unconditional `std::filesystem` branch |
| `util.cpp` | `boost::program_options` config-file parser + `to_internal` workaround | small C++17 INI parser in `ReadConfigFile` |
| `init.cpp` | `boost::interprocess::file_lock` + `using namespace boost` | portable `LockDataDirectory()` (`flock` POSIX / `LockFileEx` Win32) |
| `rpcdump.cpp` | `boost::posix_time` + `boost::gregorian` | `std::get_time` + `timegm`/`_mkgmtime` |
`wallet.cpp` and `triangles-cli.cpp` only ever *mentioned* Boost in comments —
no code change needed.
### Behavior notes for review
- **Config parser**: `name = value`; a line whose first non-whitespace char is
`#` is a comment; blank lines ignored; inline `#` is NOT a comment (so
`rpcpassword` may contain `#`). First value wins for single-valued settings;
`-name` keying and `nofoo=` negative-setting interpretation preserved.
- **File lock**: exclusive, non-blocking; the fd/handle is held for process
lifetime and released by the OS on exit (matches the old file_lock lifetime).
- **Dump time parser**: same five accepted formats, parsed as UTC.
### CMake note
`program_options` is no longer used by any source file and can be dropped from
the `find_package(Boost ... COMPONENTS ...)` list once the remaining two files
are migrated. It is left in place for now because removing it before the Asio
migration provides no benefit and the component is harmless if installed.
### RPC server (done — `trianglesrpc.cpp`)
The JSON-RPC/HTTP server previously used `boost::asio` (async sockets +
`boost::asio::ssl`), `boost::bind`, `boost::iostreams`,
`boost::shared_ptr`/`weak_ptr`, and `boost::system::error_code`. It was
rewritten onto **raw BSD sockets** behind a small `std::iostream`
(`src/rpc_httpsocket.h`), preserving the thread-per-connection model so the
HTTP parser, JSON-RPC dispatch, REST handler, and the blocking SSE handler are
all unchanged.
- New `src/rpc_httpsocket.h`: `CSocketIOStream` (a `std::iostream` over a
`SOCKET`), `ConnectRPCSocket()`, `BindRPCSockets()` (separate IPv4/IPv6
listeners, loopback unless `-rpcallowip`), `SockaddrToString()`.
- `ThreadRPCServer2` now binds sockets and runs a `select()`-based accept loop
that spawns `ThreadRPCServer3` per connection.
- `ClientAllowed` takes a numeric IP string.
- `CallRPC` connects via a raw socket.
- **`-rpcssl` is removed.** RPC TLS was a rarely used Asio::ssl feature; for
remote access, front the port with stunnel/nginx or reach it over SSH/Tor
(the same decision Bitcoin Core made). A warning is logged if `-rpcssl` is set.
### Qt URI handler (done — `qt/qtipcserver.cpp`)
The `triangles:` single-instance URI handoff used
`boost::interprocess::message_queue` + `boost::posix_time`. Rewritten onto
`QLocalServer` / `QLocalSocket` (QtNetwork), keeping the existing polling-thread
model via the blocking `waitForNewConnection` / `waitForReadyRead` /
`waitForConnected` methods (no Qt event loop required). `Qt5::Network` added to
the Qt find_package and the `triangles-qt` link.
### CMake
- `Boost::program_options`, `Boost::thread`, `Boost::chrono` removed from the
`triangles_common` link — Triangles' own objects reference no Boost symbols.
## Remaining
Two things still pull Boost into the build; neither is Triangles source:
1. **Embedded i2pd router.** When built with the embedded I2P router, the
bundled `libi2pd.a` / `libi2pdclient.a` link Boost
(`program_options`, `thread`, `chrono`, `filesystem`, `system`). The
i2pd-specific link block (and the top-level `find_package(Boost ...)`) are
therefore left intact. Fully dropping Boost from the build requires either a
Boost-free i2pd build or disabling the embedded router. This is an upstream
i2pd concern, not Triangles code.
2. **Unit tests.** `src/test/*` use the Boost.Test framework
(`Boost::unit_test_framework`). Optional follow-up: port to a header-only
framework (e.g. Catch2/doctest) to remove the last first-party Boost use.
When both are addressed, `find_package(Boost ...)` can be removed entirely.

The node will connect to seed nodes over Tor and sync the blockchain automatically. ```
### Existing Wallet Holders The node will connect to seed nodes over Tor and sync the blockchain automatically.
If you have a `wallet.dat` from the original Triangles network: ### Chain Database (RocksDB)
1. Place your `wallet.dat` in `~/.triangles/` (Linux) or `%APPDATA%\triangles\` (Windows) The chain database (block index, transaction index, UTXO set, address index) uses **RocksDB by default**. RocksDB gives faster sync and lookups than the legacy LevelDB backend through parallel compaction, bloom filters, and a larger write buffer and block cache (tunable with `-dbcache=<MB>`).
2. Start the wallet - it will sync the blockchain and your balance will appear automatically
3. No migration or special action is needed - all keys and balances are preserved If you are upgrading a node that already has a LevelDB chain database (`txleveldb/` in your data directory), it is migrated automatically on first launch: the chain state is copied into a new `rocksdb/` directory and verified (record count, UTXO count and value, best-chain hash, and DB format must all match) before use. The original `txleveldb/` directory is left untouched as a fallback and is never modified.
### Staking To select a backend explicitly:
To stake, your wallet must be: ```bash
- Running with `staking=1` in the config trianglesd -chaindb=rocksdb # default
- Connected to at least one peer trianglesd -chaindb=leveldb # legacy backend (retained for fallback/migration)
- Containing coins with sufficient coin-age (mature inputs) ```
Check staking status: Migration can also be triggered or forced manually:
```bash
trianglesd getstakinginfo ```bash
``` trianglesd -migratechaindb # migrate txleveldb -> rocksdb if not already done
trianglesd -migratechaindbforce # re-migrate, replacing any existing rocksdb/
### Encrypted Messaging ```
Send and receive encrypted messages between wallet addresses: ### Existing Wallet Holders
```bash If you have a `wallet.dat` from the original Triangles network:
# Enable messaging
trianglesd smsgenable 1. Place your `wallet.dat` in `~/.triangles/` (Linux) or `%APPDATA%\triangles\` (Windows)
2. Start the wallet - it will sync the blockchain and your balance will appear automatically
# Send a message 3. No migration or special action is needed - all keys and balances are preserved
trianglesd smsgsend <your-address> <recipient-address> "Hello from Triangles!"
### Staking
# Check inbox
trianglesd smsginbox all To stake, your wallet must be:
- Running with `staking=1` in the config
# Send anonymous message - Connected to at least one peer
trianglesd smsgsendanon <recipient-address> "Anonymous message" - Containing coins with sufficient coin-age (mature inputs)
```
Check staking status:
Messages are encrypted end-to-end using AES and distributed through the peer network in time-bucketed batches. ```bash
trianglesd getstakinginfo
### Tor Support ```
Triangles is designed as a Tor-only network. Install the Tor daemon and configure your proxy: ### Encrypted Messaging
```
# triangles.conf Send and receive encrypted messages between wallet addresses:
proxy=127.0.0.1:9050
``` ```bash
# Enable messaging
To run your own hidden service, add to `/etc/tor/torrc`: trianglesd smsgenable
```
HiddenServiceDir /var/lib/tor/triangles/ # Send a message
HiddenServiceVersion 3 trianglesd smsgsend <your-address> <recipient-address> "Hello from Triangles!"
HiddenServicePort 24112 127.0.0.1:24112
``` # Check inbox
trianglesd smsginbox all
Then set `externalip=<your-onion-address>` in `triangles.conf`.
# Send anonymous message
## RPC Commands trianglesd smsgsendanon <recipient-address> "Anonymous message"

# RocksDB as the default chain database backend
This change finishes the RocksDB chain-database backend, makes it the default,
and provides a transparent migration path off LevelDB. **No consensus rules
change** — only how the block index / tx index / UTXO set / address index are
stored on disk. On-disk key bytes remain identical across both backends, which
is what the migration and the dual-backend equivalence tests rely on.
## What changed
### 1. Fixed the column-family iteration bug (the real "unfinished" blocker)
The RocksDB backend routed keys into per-prefix **column families**
(`blockindex`, `txindex`, `utxo`, `addrindex`) on write, but the read path —
both `CRocksTxDB::NewIterator()` and `CRocksTxDB::LoadBlockIndex()` — only ever
iterated the **default** column family. With column families enabled:
- `LoadBlockIndex()` loaded **zero** blocks (block-index records were in a
non-default CF the loader never scanned),
- UTXO snapshot dumps and address-index range scans saw nothing, and
- the migration verifier `CollectStats()` reported a record-count mismatch.
This is why `-chaindb=rocksdb` "compiled clean but was never runtime-valid."
**Fix:** column-family partitioning is disabled. `GetCF()` now always returns
the default CF, so writes, point reads, `Exists`, `Erase`, and full-keyspace
iteration are mutually consistent — and byte-identical to the single-keyspace
LevelDB backend. New databases are created single-CF; pre-existing experimental
multi-CF databases are still opened (for compatibility) but should be
re-migrated or reindexed. RocksDB still delivers its performance win from
parallel compaction, bloom filters, large write buffer, and block cache — the
CF split was a premature optimization, not the source of the speedup.
Re-introducing column families is a tracked follow-up that first requires
CF-aware iterators (a multiplexed merge across CFs) in `NewIterator()` /
`LoadBlockIndex()`.
### 2. Automatic LevelDB -> RocksDB migration on startup
`init.cpp` now runs the migration automatically when RocksDB is the active
backend and the only chain DB present is a legacy `txleveldb/` (no `rocksdb/`
yet). `MaybeMigrateLevelDbToRocksDb()` is a no-op when there is nothing to
migrate, so it is safe on every launch. The LevelDB source is never modified;
it remains a fallback.
### 3. RocksDB is now the default backend
`-chaindb` defaults to `rocksdb` (was `leveldb`). LevelDB stays selectable with
`-chaindb=leveldb` and is retained as migration source + fallback. Full removal
of LevelDB is deferred to a later phase, after live-chain validation.
### 4. Fixed `NeedsBootstrap()` to recognize the RocksDB directory
`Bootstrap::NeedsBootstrap()` checked for `txleveldb/` but not `rocksdb/`. With
RocksDB as default, a fully-synced rocksdb-only node would have been treated as
"fresh" and could have triggered a bootstrap download over a healthy chain on
every restart. It now treats a `rocksdb/` directory as an existing chain DB.
## Files changed
- `src/txdb-rocksdb.cpp` — disable CF routing; single-CF open; remove dead CF tables
- `src/txdb-rocksdb.h` — update CF member docs
- `src/txdb-factory.cpp` — default backend `leveldb` -> `rocksdb`
- `src/txdb.h` — update factory doc comment
- `src/init.cpp` — auto-migrate on startup when RocksDB active + legacy LevelDB present
- `src/bootstrap.cpp` — `NeedsBootstrap()` recognizes `rocksdb/`
- `src/test/chaindb_runtime_tests.cpp` — update default-backend expectations
- `README.md` — document RocksDB default + migration
## Build
```bash
cmake -B build -G Ninja -DBUILD_QT=ON -DBUILD_TESTS=ON
cmake --build build
```
RocksDB is required (`librocksdb-dev` >= 7.4 on Debian/Ubuntu,
`mingw-w64-x86_64-rocksdb` on MSYS2, `rocksdb` on Homebrew).
## Tests
```bash
# RocksDB wrapper runtime smoke tests (the class the daemon uses at runtime)
./build/bin/test_chaindb_runtime
# LevelDB/RocksDB byte-for-byte migration equivalence
./build/bin/test_chaindb_equivalence
# Full unit suite
./build/bin/test_triangles
```
Expected after this change:
- `get_chain_data_dir_default_is_rocksdb` passes (default resolves to rocksdb).
- `iterator_walks_every_key_in_sorted_order` passes (the `"banana"` key, which
previously routed to a non-default CF the iterator never read, now lives in
the default CF and is iterated).
- Migration verification (`CollectStats` / `StatsMatch`) passes end-to-end.
## Live-chain validation checklist (V6 task T010)
This is the step that cannot be done without real chain data and must be run on
a node before release:
1. **Migrate a real chain.** On a node with an existing `txleveldb/`, launch the
new binary (default backend). Confirm the log shows
`ChainDB: RocksDB backend active with a legacy LevelDB present; migrating
automatically.` followed by `ChainDB migration: verified N records ... best=<hash>`.
2. **Verify block index loads.** Confirm `LoadBlockIndex()` reports the correct
`height=` and `hashBestChain=` (matching the prior LevelDB tip), not 0.
3. **Compare RPC output.** `getinfo`, `getblockcount`, `getbestblockhash`, and a
spot-check of `gettxout` / address-index queries must match a LevelDB run of
the same datadir (`-chaindb=leveldb`).
4. **Restart twice.** Confirm no spurious bootstrap download fires and the tip is
stable across restarts.
5. **Sync new blocks.** Let the node accept and stake new blocks; confirm UTXO
set and money supply stay consistent.
6. **Benchmark.** Use `contrib/bench/bench-chaindb.sh --backends=rocksdb` vs
`leveldb` to confirm the speedup on this hardware.
## Rollback
Set `-chaindb=leveldb` in `triangles.conf` (or on the command line). The
original `txleveldb/` is untouched by migration, so reverting is immediate.
## Remaining follow-ups
- CF-aware iteration, then re-enable column-family partitioning for independent
compaction/caching.
- Retire LevelDB entirely (remove `txdb-leveldb.*`, drop the `-chaindb=leveldb`
option and the bundled LevelDB dependency) once RocksDB is validated in
production for at least one release cycle.

# Wallet storage: Berkeley DB → SQLite
Goal: retire Berkeley DB as the wallet store and make **SQLite the default**
wallet backend, with a transparent, non-destructive migration of existing
`wallet.dat` files. This removes the single ugliest build dependency (BDB 5.3
with C++ bindings, hand-built on RHEL/MSYS2) and gives the wallet a modern,
maintainable, single-file store — the kind exchanges expect.
No consensus or wire behavior changes. The on-disk *record encoding* is
unchanged: keys and values are the exact `SER_DISK / CLIENT_VERSION` bytes
`CWalletDB` already produces, just stored as `(key BLOB, value BLOB)` rows in
SQLite instead of Berkeley B-tree entries. That byte-for-byte identity is what
makes migration a verbatim copy.
## Delivered in this pass
New, self-contained modules (do not disturb the working Berkeley path):
| File | Purpose |
|------|---------|
| `src/walletdb-base.h` | Backend-agnostic seam: `WalletDatabase`, `WalletBatch` (raw byte Read/Write/Erase/Has + cursor + txn), `WalletCursor`; `ResolveWalletDbKind()` / `MakeWalletDatabase()` declarations. |
| `src/walletdb-sqlite.h/.cpp` | `SQLiteDatabase` / `SQLiteBatch` — single `main(key BLOB PRIMARY KEY, value BLOB)` table, `synchronous=FULL`, prepared statements, transactions, cursor, online-backup, `integrity_check`. App-id/user-version stamping to reject foreign DBs. |
| `src/walletmigrate.h/.cpp` | `MaybeMigrateBerkeleyWalletToSQLite()` — detects a Berkeley `wallet.dat`, copies every record verbatim into a temp SQLite file, verifies the row count, backs up the original to `wallet.dat.bdb.bak`, then swaps SQLite into place. Idempotent and non-destructive. |
| `src/walletdb-factory.cpp` | `ResolveWalletDbKind()` (default **sqlite**, `-walletdb=bdb` fallback) and `MakeWalletDatabase()` (SQLite implemented). |
| `src/walletdb-batch.h` | `CWalletBatchTyped` — typed Read/Write/Erase/Exists + cursor over `WalletBatch`, byte-identical to the old `CDB` templates. The drop-in base for `CWalletDB`. |
Build wiring:
- `find_package(SQLite3 REQUIRED)` in the top-level `CMakeLists.txt`.
- `SQLite::SQLite3` linked into `triangles_common`; the new sources added to `CORE_SOURCES`.
## Remaining integration (compile-in-the-loop)
The new modules are complete but `CWalletDB` is not yet routed through the seam
— it still inherits Berkeley `CDB`. This is the mechanical-but-careful step that
needs a compiler in the loop. **It must be done and landed as one unit** (it
touches `walletdb.h`, `walletdb.cpp`, `wallet.cpp`, `db.cpp`, and `init.cpp`):
re-basing ~800 lines of funds-critical code is exactly the kind of change that
should be compiled and run against a real `wallet.dat` rather than committed
blind.
1. **Typed wrappers over the batch — DONE.** `src/walletdb-batch.h`
(`CWalletBatchTyped`) provides `Read/Write/Erase/Exists` + cursor over a
`WalletBatch`, byte-identical to `CDB`'s templates. `CWalletDB` derives from
it instead of `CDB`.
2. **Re-base `CWalletDB`.** Hold a `std::unique_ptr<WalletDatabase>` +
`WalletBatch` obtained from `MakeWalletDatabase("wallet.dat", err)` instead of
deriving from `CDB`. Route `TxnBegin/Commit/Abort` to the batch.
3. **Cursors.** Replace `GetAtCursor` / `GetTxnCursor` / `ReadAtCursor`
(Berkeley `Dbc*`, `DB_NEXT`) in `walletdb.cpp` (`LoadWallet`,
`ReorderTransactions`) with `WalletBatch::GetNewCursor()` + `WalletCursor::Next()`.
4. **Berkeley-specific call sites.**
- `BackupWallet()` / `AutoBackupWallet()` → `WalletDatabase::Backup()`.
- `CDB::Rewrite()` (used by `CWallet::EncryptWallet`) → `WalletDatabase::Rewrite()`
(VACUUM). Unencrypted-key cleanup already happens via explicit `Erase`.
- `bitdb.Flush()` / env shutdown in `init.cpp` → `WalletDatabase::Flush()/Close()`
(no-op for SQLite).
5. **Berkeley behind the same seam (optional but recommended).** Add a thin
`BerkeleyDatabase`/`BerkeleyBatch` adapter wrapping the existing `CDBEnv`/`CDB`
so `-walletdb=bdb` routes through `MakeWalletDatabase` too, instead of the
legacy path. Keeps one code path for one release, then delete BDB entirely.
6. **Run the migration on startup.** In `init.cpp`, before the wallet is loaded
and when the backend is SQLite, call
`MaybeMigrateBerkeleyWalletToSQLite(GetDataDir()/strWalletFileName, err)`.
## Gating
```
trianglesd # SQLite (default)
trianglesd -walletdb=bdb # Berkeley fallback (retained for one release)
```
## Validation checklist (must pass before release)
Cannot be verified without a build + a real wallet. Run on a node:
1. **Build** with `-DBUILD_TESTS=ON`; confirm SQLite is found and linked.
2. **Fresh wallet**: start with no wallet → a SQLite `wallet.dat` is created;
`getnewaddress`, `getinfo` work; restart preserves keys/balance.
3. **Migration**: copy a real Berkeley `wallet.dat` into the datadir, start the
node. Confirm: `wallet.dat.bdb.bak` is created, `wallet.dat` is now SQLite
(`sqlite3 wallet.dat "PRAGMA integrity_check;"` → `ok`), and
`listaddressgroupings` / `getbalance` / `dumpwallet` match a `-walletdb=bdb`
run against the `.bdb.bak` original.
4. **Key parity**: `dumpwallet` before (bdb) and after (sqlite); diff must be
empty (same keys, labels, metadata, HD seed).
5. **Encryption**: `encryptwallet`, restart, `walletpassphrase`, sign/spend.
6. **Backup/restore**: `backupwallet`, restore into a fresh datadir, verify
balance and spend.
7. **Send/receive + staking** over a few blocks; confirm new keys/txns persist
across restart.
8. **Crash safety**: kill -9 mid-write; restart; `integrity_check` ok, no loss.
## Follow-ups
- Add `test_wallet_sqlite` unit tests (round-trip, migration parity, cursor).
- Once SQLite is validated for a release, remove `-walletdb=bdb`, delete
`db.cpp`/`walletdb`'s Berkeley code, and drop the `BerkeleyDB` CMake
dependency — completing the retirement.

// Live runtime smoke tests for the RocksDB chain-DB backend.
//
// Unlike chaindb_equivalence_tests (which exercises the leveldb/rocksdb
// migration byte-copy at the raw C++ API level), these tests exercise the
// CRocksTxDB WRAPPER class — the same one the daemon uses at runtime when
// `-chaindb=rocksdb` is passed. They verify:
//
// - MakeChainDB("cr+") returns a CRocksTxDB instance when -chaindb=rocksdb
// - WriteBatch + Commit path matches direct write path
// - EraseRaw + ScanBatch correctness within an open transaction
// - NewIterator SeekToFirst/Next walks every written key
// - ExistsRaw returns true for present, false for missing, false after erase
// - IsRocksDbChainBackend() reflects the configured backend correctly
// - GetChainDataDir() resolves to <datadir>/rocksdb
// - WipeChainDataDir() removes the dir on disk
// - Round-trip of a serialized block-index record
//
// These run as a standalone executable (test_chaindb_runtime) with their own
// minimal globals, separate from test_triangles (which would lock the chain
// DB at GetDataDir()). Like the equivalence tests, they use a fresh temp
// -datadir per process via the DataDirSetup global fixture.

// Tests for the SnapshotNet P2P snapshot chunk distribution protocol
// (Triangles v6 / branch v6/snapshotnet-rocksdb).
//
// Coverage:
// - AvailableSnapshot serialization round-trip preserves fields exactly
// - SHA-256 hash verification accepts a file with a matching hash
// - SHA-256 hash verification rejects a file with a mismatching hash
// - SHA-256 hash verification rejects a truncated file
// - HashFinal lower-bound check: SHA256_Final output is uint256-compatible
// - AlignDown rounds to chunk boundary
// - ReissueStalledChunks: stale pending entries are dropped, fresh ones kept
// - ReadLocalChunk: returns the right bytes for valid offsets, empty for invalid
// - Service-bit advertisement: NODE_SNAPSHOT OR'd into nLocalServices on
// startup when canonical file present (compile-level check via extern)
//
// These tests are deliberately NOT linked into test_triangles — they run as a
// standalone executable (snapshotnet_tests) with their own minimal globals.
// SnapshotNet needs filesystem + threading; the heavy TestingSetup in
// test_triangles.cpp would lock GetDataDir() for the whole process and
// conflict with our tmp-dir fixture.
//
// Build: see src/test/CMakeLists.txt target `snapshotnet_tests`.

// Backend-agnostic wallet storage seam.
//
// Historically CWalletDB derived directly from CDB (Berkeley DB). To allow the
// wallet to be stored in SQLite instead, storage is abstracted behind two
// interfaces modeled on Bitcoin Core's WalletDatabase / DatabaseBatch:
//
// WalletDatabase - owns the on-disk database (open/close/flush/backup/
// rewrite) and hands out batches.
// WalletBatch - a unit of work against the database: raw byte-level
// Read/Write/Erase/Exists, a cursor for full scans, and an
// optional atomic transaction.
//
// Only RAW BYTES cross this interface. All key/value (de)serialization stays in
// CWalletDB via CDataStream with SER_DISK / CLIENT_VERSION, exactly as before,
// so the on-disk record encoding is identical across backends. That byte
// identity is what makes the Berkeley -> SQLite migration a verbatim key/value
// copy.
