perf: RTL Go-native migration — 27 optimizations, DML up to 70-90x
Systematic pass through PRG hot paths, promoting them to Go RTL while
preserving Harbour/FiveSql2 semantics. Full log in
docs/RTL-Go-Native-Migration.md.
Bench (bench_sql) vs 2026-04-08 baseline
- B1 SELECT * 2,192 → 114 µs (19x)
- B6 INNER JOIN 9,291 → 233 µs (40x)
- B7 CTE simple 8,037 → 129 µs (62x)
- B9 ROW_NUMBER 3,705 → 265 µs (14x)
- B10 RANK PARTITION 4,748 → 309 µs (15x)
- B12 INSERT (WA cache) 4,319 → 63 µs (69x)
- B13 UPDATE (WA cache) 6,144 → 68 µs (90x)
- B15 CTE+WIN+JOIN 18,395 → 1,873 µs (10x)
Infrastructure
- HbHash O(1) Index preserving insertion order (Harbour KEEPORDER)
- HbDeepClone Go RTL (scalar-sharing, immutable hash keys)
- MEMRDD auto-imported via gengo; all Five programs get mem:name driver
- SQL plan + pcode caches (s_hPlanCache, s_hDmlPcodeCache)
- Opt-in SqlWACacheEnable — dbUseArea/Close/Commit batched for DML
SQL engine
- FiveSql2 lexer ported to Go (byte FSM) with combined automatic
template parameterization (literals → ?, concat queries share plan)
- Go RTL: SqlDistinct, SqlGroupRows, SqlWindowPartitions,
SqlWindowSortPartition, SqlWindowAssignRank, SqlComputeAggSimple,
SqlBulkInsert, SqlBulkUpdate, SqlExprHasAgg, SqlEvalHaving
- CTE / subquery / driving-table materialize paths use MEMRDD
- SqlCoerce/SqlCmp/SqlIsTrue helpers moved from PRG to Go
- SqlBulkUpdate defers Flush when WA cache active (APFS fsync was
dominant B13 cost — 1.6ms/call → gone)
Correctness fixes uncovered during migration
- ASort default path now sorts dates/logicals/timestamps (was no-op)
- ORDER BY default NULL placement matches PRG SqlRowCompare across
Go fast path; explicit NULLS FIRST/LAST honored by both paths
- SqlBulkUpdate respects EXCLUSIVE vs SHARED mode record locks
- SqlCmp/SqlCmpEq normalize NumInt vs Double (caught by test 6b)
Verification
- go test ./... ALL PASS
- FiveSql2 test_sql1999 43/43
- tests/compat_harbour 56/56 (+5 new: ASort dates/logicals,
AScan int cross-type)
- Regression test test_null_order.prg for ORDER BY NULL ordering

feat: FiveSql2 43/43, @byref, mutable closure, RTL 479, DateTime fix
Major changes since last commit:
- FiveSql2 SQL:1999 engine (10,458 LOC) — 43/43 ALL PASS
- 21 compiler/runtime bugs fixed (short-circuit AND/OR, FOR LOOP, etc.)
- @byref pass-by-reference via RefCell pattern
- Mutable closure capture (EnsureLocalRef + RefCell sharing)
- RTL: 400 → 479 functions (+79: file, string, datetime, hash, UTF-8)
- DateTime/Timestamp fully working (hb_DateTime, hb_Hour/Min/Sec, display)
- Reserved word guard (39 keywords blocked from function calls)
- AEval arg order fix (element before index)
- Closure capture redecl fix (unique _cap_ names per block)
- Hash/string indexing in ArrayPush/ArrayPop
- Harbour compat test suite: 51/51
- 4 docs: Porting Report, Implementation Plan, Optimization Plan, Commercialization
