From 38e7932b6d3106e253f1d0222e8a412aef449593 Mon Sep 17 00:00:00 2001 From: Serhii Savchuk Date: Mon, 27 Apr 2026 13:34:27 +0300 Subject: [PATCH 01/21] test(rfl): consolidate non-duplicate coverage from spec migration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds 624 unique test assertions on top of Anton's test/rfl/ corpus, deduped against his parallel rewrite (commit 536fef4 et al). Stats: * 35 modified files — our backup was a strict superset of upstream; replace upstream wholesale. Whitespace-only diffs in arith/abs, arith/ceil, arith/floor, arith/neg, arith/round, cmp/ge, cmp/gt, cmp/ne were also false-positive "Anton-only" results from sorting with extra spaces. * 12 new files — coverage Anton didn't write at all: test/rfl/datalog/rule.rfl — full EAV / rule / TC / negation test/rfl/embedding/hnsw.rfl — HNSW index build/query/info test/rfl/integration/arena.rfl — 100k-element churn + .sys.gc test/rfl/integration/cow.rfl — copy-on-write aliasing test/rfl/integration/morsel.rfl — 1023/1024/1025 + 2047/2048/2049 test/rfl/integration/optimizer.rfl — filter reorder, pushdown, selection-bitmap edges test/rfl/integration/str_pool.rfl — 12-byte SSO boundary test/rfl/system/csv_roundtrip.rfl — schema-less .csv.read test/rfl/system/splayed.rfl — set/get-splayed round-trip test/rfl/table/modify.rfl — functional column update test/rfl/table/pivot.rfl — wide reshape, sum/count aggr test/rfl/table/select.rfl — 50 select-clause assertions Coverage delta vs origin/master: Tests: 921/922 → 933/934 (+12 unique tests) Lines: 63.4% → 63.9% (+217 lines) Functions: 77.5% → 78.0% (+8 functions) Co-Authored-By: Claude Opus 4.7 (1M context) --- test/rfl/agg/sum.rfl | 13 +++ test/rfl/arith/abs.rfl | 28 +++++- test/rfl/arith/add.rfl | 130 +++++++++++++++++++++++++- test/rfl/arith/ceil.rfl | 19 +++- test/rfl/arith/div.rfl | 44 ++++++++- test/rfl/arith/floor.rfl | 18 +++- test/rfl/arith/mod.rfl | 31 +++++- test/rfl/arith/mul.rfl | 62 ++++++++++-- test/rfl/arith/neg.rfl | 39 +++++++- test/rfl/arith/round.rfl | 25 ++++- test/rfl/arith/sqrt.rfl | 6 ++ test/rfl/arith/sub.rfl | 74 ++++++++++++++- test/rfl/cmp/eq.rfl | 49 +++++++++- test/rfl/cmp/ge.rfl | 27 +++++- test/rfl/cmp/gt.rfl | 37 +++++++- test/rfl/cmp/le.rfl | 15 ++- test/rfl/cmp/lt.rfl | 17 ++++ test/rfl/cmp/ne.rfl | 23 ++++- test/rfl/collection/rand.rfl | 7 ++ test/rfl/collection/til.rfl | 5 + test/rfl/datalog/rule.rfl | 145 +++++++++++++++++++++++++++++ test/rfl/embedding/hnsw.rfl | 25 +++++ test/rfl/hof/apply.rfl | 13 +++ test/rfl/hof/fold.rfl | 16 ++++ test/rfl/hof/map.rfl | 7 ++ test/rfl/hof/scan.rfl | 6 ++ test/rfl/integration/arena.rfl | 25 +++++ test/rfl/integration/cow.rfl | 20 ++++ test/rfl/integration/joins.rfl | 36 ++++++- test/rfl/integration/morsel.rfl | 52 +++++++++++ test/rfl/integration/null.rfl | 6 ++ test/rfl/integration/optimizer.rfl | 54 +++++++++++ test/rfl/integration/str_pool.rfl | 44 +++++++++ test/rfl/sort/asc.rfl | 36 +++++++ test/rfl/sort/iasc.rfl | 11 +++ test/rfl/sort/rank.rfl | 20 +++- test/rfl/strop/like.rfl | 29 ++++++ test/rfl/system/csv_roundtrip.rfl | 75 +++++++++++++++ test/rfl/system/serde.rfl | 12 +++ test/rfl/system/splayed.rfl | 32 +++++++ test/rfl/table/meta.rfl | 25 ++++- test/rfl/table/modify.rfl | 28 ++++++ test/rfl/table/pivot.rfl | 25 +++++ test/rfl/table/select.rfl | 117 +++++++++++++++++++++++ test/rfl/temporal/date.rfl | 36 +++++++ test/rfl/temporal/time.rfl | 13 +++ test/rfl/type/as.rfl | 39 ++++++++ 47 files changed, 1572 insertions(+), 44 deletions(-) create mode 100644 test/rfl/datalog/rule.rfl create mode 100644 test/rfl/embedding/hnsw.rfl create mode 100644 test/rfl/integration/arena.rfl create mode 100644 test/rfl/integration/cow.rfl create mode 100644 test/rfl/integration/morsel.rfl create mode 100644 test/rfl/integration/optimizer.rfl create mode 100644 test/rfl/integration/str_pool.rfl create mode 100644 test/rfl/system/csv_roundtrip.rfl create mode 100644 test/rfl/system/splayed.rfl create mode 100644 test/rfl/table/modify.rfl create mode 100644 test/rfl/table/pivot.rfl create mode 100644 test/rfl/table/select.rfl diff --git a/test/rfl/agg/sum.rfl b/test/rfl/agg/sum.rfl index 2925e651..01e4ba7c 100644 --- a/test/rfl/agg/sum.rfl +++ b/test/rfl/agg/sum.rfl @@ -11,3 +11,16 @@ ;; linearity: scales with constant — falsifies sum ≡ 0.

Now both dispatch sites — the bytecode VM (eval.c:1656) and the tree- walking eval (eval.c:2378) — raise: arity: expected N arg(s), got M `and` and `or` were registered as RAY_BINARY but Anton's tests expected variadic fold semantics ((and a b c) -> fold AND). Switch them to RAY_VARY via ray_and_vary_fn / ray_or_vary_fn — left-fold over the existing binary kernel. The (and X Y) DAG path through select where: clauses still emits OP_AND / OP_OR via the expression compiler, so fused execution is unaffected.

Equality comparisons (==/!=) worked because they could just check interned IDs, but ordering had no implementation at all and fell through to the is_numeric() guard. Add sym_atom_cmp(a, b): - Fast path: equal interned IDs => identical text (interning gives one ID per text), return 0 without touching the global sym table. - Slow path: ray_sym_str(id) returns a RAY_STR atom; ray_str_cmp delegates to ray_str_t_cmp which uses the 12-byte SSO inline path for short symbols and prefix-then-fullcompare for pooled ones. Wire it into ray_gt_fn / ray_lt_fn / ray_gte_fn / ray_lte_fn at the same dispatch site as the existing -RAY_GUID branch. Vector and broadcast paths inherit the fix automatically — atomic_map_binary unboxes SYM elements via collection_elem (-> ray_sym(id) atom), so each pairwise call lands in the new branch. The pre-fix probe (test/rfl/cmp/gt.rfl:41-44, "(> 'b 'a) !- type") is replaced with positive assertions covering atoms, broadcast, vec/vec, and the SSO inline/pooled boundary. Mirror coverage added to lt.rfl, ge.rfl, le.rfl.

No good reason for the inconsistency: in Rayforce typed nulls live in a separate nullmap bit, so INT_MIN is just a regular value and the "overflow protection" rationale that justifies widening in some languages doesn't apply here. Switch the i16/i32 branches to make_i16/make_i32: (abs -5h) -> 5h (i16, was i64) (abs -5i) -> 5i (i32, was i64) (abs [-1h 2h]) -> [1h 2h] (I16, was I64) Update test/rfl/arith/abs.rfl and the type_preservation.rfl regression table: abs now joins neg/floor/ceil under the "preserve narrow ints" rule. Coverage of remaining type-promotion oddities (left intentional): - sum widens I16/I32 → i64 (overflow guard) - round of int → f64 (mathematically noop, but produces float anyway) Both pinned in type_preservation.rfl so future changes surface.

But ray_neg_fn (and every other atomic unary kernel: abs, floor, ceil, round, sqrt, log, exp, not) is written for a single atom and rejects positive-typed (vector) input with "type". call_fn2 already had the parallel routing for binary atomic builtins: if ((fn->attrs & RAY_FN_ATOMIC) && (is_collection(a) || ...)) return atomic_map_binary(f, a, b); call_fn1 simply forgot the unary mirror. Add it. Affects every code path that uses call_fn1 — modify, fold (1-arg form), the apply 1-arg case — so any future caller now gets vector auto-mapping for free, matching the user's intuition that "if it works in map, it should work everywhere".

So `(like "hello" "h*")` returned true via eval but matched 0 rows in `select where: (like s "h*")` — `*` was literal under the SQL matcher. And the eval path could be DoS'd with a 20-star pattern. Replace all three with one shared implementation in src/ops/glob.[ch]: - Iterative two-pointer with last-star backtrack (glibc fnmatch style). O(n*m) worst case; 32-star pattern that pre-fix took >5s now finishes in microseconds. - Glob syntax matching the documented contract: * (any), ? (one), [abc] / [a-z] / [!abc] (character class). - ray_glob_match (case-sensitive) and ray_glob_match_ci (folds ASCII letters on both sides). eval path (strop.c::ray_like_fn) and DAG path (string.c::exec_like / exec_ilike) both call the same matcher — semantics now identical. Tests: * test/rfl/strop/like.rfl extended with character classes, ranges, negated classes, an adversarial 20-star catastrophic-backtracking guard, and explicit eval-path-≡-DAG-path parity assertions. * test/test_exec.c: stale C-test using "bar%" (SQL syntax) updated to "bar*" (glob). Docs: website/docs/rayfall-functions.html updated to mention [abc] / [a-z] / [!abc] (already implemented; previously undocumented).

Add ray_mkdir_p (POSIX + Win32, src/store/fileio.c) with mkdir -p semantics. Use it from ray_splay_save instead of the single-level ray_mkdir. 2. ray_read_parted (get-parted) unconditionally called ray_sym_load("/sym") and propagated its failure as "io" — but set-splayed only writes per-table sym files inside the leaf splayed dir, never a root-level one for symbol-less tables. Stat the file and skip the load if absent. After both: (set-splayed "/tmp/db/2024.01.01/t/" t0) writes the partition correctly; (get-parted "/tmp/db/" 't) returns a 10-row / 3-column lazy table (1 MAPCOMMON partition-key + 2 data columns), parity with the v1 behaviour. Tests: extend test/rfl/system/splayed.rfl with the nested-mkdir case and a 2-partition get-parted round-trip (count = 10, columns = 3). Known limitation (separate task): direct (at p 'col) on a PARTED column doesn't materialize values yet — only the select-where path exercises the lazy reader. Filed for follow-up.

Reviewed each against the existing test/rfl/ corpus; salvaged what wasn't covered: * test/rfl/integration/sort_radix_boundary.rfl (new) — pin every type's sort exit values at N=4097, just over the 2^12 radix-strategy threshold. Covers asc/desc/iasc/idesc/xasc/xdesc/select-orderby/ group-by-then-sort/distinct/rank across i64, f64, SYM, STR, BOOL, DATE, TIMESTAMP, plus null-bearing variants. * test/rfl/null/sort.rfl (extended) — add xasc-on-null-keyed-table (null sorts first, count preserved) and take-with-nulls slicing semantics. Anton's existing file covered asc/desc/iasc/idesc with nulls but not xasc or take. The other two files duplicated Anton's null/* and arith/div coverage (Float div-by-zero already produces 0Nf in his test/rfl/arith/div.rfl, INT64 boundary already in test/rfl/integration/null.rfl), so dropped. Plus removed: rayforce.cov — clang/llvm runtime artifact test/bugs/ — 6 of 7 already migrated as upstream tests; legacy duplicates extract_v1_tests.py + v1_tests*.rfl — Python interim, generation output; we don't ship Python in the test pipeline test_null_full / 100k / parallel / bugs.rfl — used renamed verbs (write-csv, antijoin) that don't exist in current Rayforce, and what they tested is already covered Co-Authored-By: Claude Opus 4.7 (1M context) --- test/rfl/integration/sort_radix_boundary.rfl | 87 ++++++++++++++++++++ test/rfl/null/sort.rfl | 13 +++ 2 files changed, 100 insertions(+) create mode 100644 test/rfl/integration/sort_radix_boundary.rfl diff --git a/test/rfl/integration/sort_radix_boundary.rfl b/test/rfl/integration/sort_radix_boundary.rfl new file mode 100644 index 00000000..a3a80c02 --- /dev/null +++ b/test/rfl/integration/sort_radix_boundary.rfl @@ -0,0 +1,87 @@ +;; Radix-threshold boundary: at N=4097 (just over 2^12 = 4096) sort +;; switches from one strategy to another internally.

Discovered while writing test/rfl/integration/cross_type_workout.rfl; that file's pinned-bug TODOs are now upgraded to type-asserting assertions. Plus per-type regression coverage in test/rfl/agg/{first,last}.rfl.

Stable, total ordering preserved. [blocker] neg/abs INT_MIN UB: -INT16_MIN / -INT32_MIN / -INT64_MIN were signed-overflow UB. Negate via unsigned cast — wraparound is defined for unsigned types and the result wraps back to INT_MIN consistently with binary `(- 0 INT_MIN)`. Added regression rows in arith/neg.rfl and arith/abs.rfl that pin INT16_MIN / INT32_MIN behaviour (via cast since `-32768h` literal is unrepresentable). [blocker] ray_mkdir_p path buffer: replace hardcoded `char buf[1024]` with `RAY_PATH_MAX` (PATH_MAX on POSIX, 4096 on Windows). Deep splayed paths like /db/yyyy.mm.dd/leaf/ now fit. [bonus] glob `%`/`_` literal-match assertions in strop/like.rfl — makes the SQL→glob consolidation explicit in tests, not just docs. [bonus] glob.h documents the lenient unterminated-class policy (matches glibc fnmatch semantics; never produces parse error).
