- Add --path:src and --threads:on to nim.cfg so tests compile without manual flags
- Add tests/config.nims for automatic path resolution in test directory
- Simplify nimble task definitions (remove redundant flags now in nim.cfg)
- Fix Dockerfile.source comment: remove obsolete nimmax reference
This makes 'nim c tests/test_all.nim' and 'nimble test' work out of the box.
ID Generators:
- AUTO_INCREMENT for INTEGER columns
- SERIAL / BIGSERIAL as syntactic sugar
- gen_random_uuid() / uuid() for UUID v4 generation
- nextval() / currval() for sequence support
- snowflake_id(node_id) for distributed 64-bit IDs
- RETURNING clause for INSERT
Deficiency Fixes:
- Comma join: FROM t1, t2 now works as implicit CROSS JOIN
- DEFAULT in restoreSchema: defaults survive server restart
- Duplicate column names: t.id instead of id in joins
- Empty result sets: always send column metadata to client
- GROUP BY non-agg columns: return first row value instead of empty
- Aggregate column names: count(*) instead of count()
Bug fix: PK uniqueness check now uses correct key format
- Top-level BEGIN/COMMIT/ROLLBACK work (server-side)
- SAVEPOINT (nested tx) does not work — BaraDB server limitation
- RETURNING parsed but ignored by BaraDB executor — server limitation

WHEN NOT MATCHED INSERT

The gossip listener used synchronous newSocket + recvFrom,
which blocks the async event loop and prevents other async
operations from running while waiting for UDP packets.
Switch to newAsyncSocket + async recvFrom so the loop can
continue processing other tasks between gossip rounds.
The previous implementation allowed multiple concurrent async calls
(query, execute, ping) to interleave writes on the same socket,
which corrupted the binary protocol framing when NodeBB fired
parallel database operations.
Add an internal _requestQueue and _requestLock so that all TCP
requests are serialized: each async operation enqueues a task,
and tasks are drained one at a time via setImmediate().
The JavaScript client reads floats via readFloatBE/readDoubleBE,
which expect IEEE-754 values in big-endian byte order.
The Nim server was writing them with copyMem in native byte order,
so on little-endian machines (x86_64) the JS side deserialized
FLOAT64 values as garbage (e.g. 1.0 became 3.03865e-319).
Fix serialization by casting to int32/int64 and using bigEndian32/
bigEndian64, mirroring the existing big-endian handling for ints.
Apply the same fix to deserialization and to fkVector elements.
- Added missing irNeg case in evalExpr (query/executor.nim)
- Unary minus previously fell through to else: return 'false'
- Added 2 tests: SELECT expression and WHERE condition
- disttxn: rollback now correctly updates participant state (was modifying a copy)
- disttxn: bare except replaced with CatchableError
- sharding: migrateData condition was always false, now correctly migrates data
- sharding: unsafe cast[string] replaced with manual byte-to-char conversion
- sharding: bare except replaced with CatchableError
- server: parseUInt replaced with parseBiggestUint for uint64 portability
