feat(json): hb_jsonDecode 2-arg byref form (Harbour-spec compatible)
...
Previously hb_jsonDecode took only (cJSON) and returned the value.
That covers most uses but not the Harbour-spec second form
nBytesParsed := hb_jsonDecode( cJSON, @xOut )
which mod_harbour / fivenode PRG (e.g. bridge_context.prg's
ctx_get / ctx_set) and any other code that wants the parse-length
relies on. The byref output was silently dropped, so a hash lookup
went through the @hOut path that was always NIL and fell back to
the default value — looking like a hash key was missing even
though the JSON parsed fine.
Now PCount() == 1 keeps the legacy return-value form; PCount() >= 2
writes the decoded value into local-2 via SetLocal (which is
already byref-aware) and returns the byte count (0 on parse error).
Verified: hb_jsonDecode('{"x":1,"y":2}', @h) writes the hash and
returns 13; the 1-arg form still returns the value as before;
Compat 56/56 + go test ./compiler/... ./hbrt/... ./hbrtl/... all pass.

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
