From 93008dbe0341e97a853734a8138c16272bd5d39f Mon Sep 17 00:00:00 2001 From: Dan Draper Date: Wed, 13 May 2026 19:20:12 +1000 Subject: [PATCH 1/3] Inline `<` / `<=` / `>` / `>=` on `eql_v2_encrypted` to ore_block term comparison MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mirrors the EQL 2.3 `=` → `hmac_256` inlining for the range operators. Each `<` / `<=` / `>` / `>=` overload (three per operator: encrypted-encrypted, encrypted-jsonb, jsonb-encrypted) becomes single-statement inlinable SQL with body `eql_v2.ore_block_u64_8_256(a) eql_v2.ore_block_u64_8_256(b)`. The plpgsql `lt` / `gt` / `lte` / `gte` helpers are kept (they're still useful for direct callers, including `eql_v2.compare`); only the operator wrappers route around them. After this change, bare-form predicates (`WHERE col < $1`, `WHERE col > $1`, …) structurally match a functional btree index on `eql_v2.ore_block_u64_8_256(col)` (using the existing DEFAULT-for-type `eql_v2.ore_block_u64_8_256_operator_class`). `ORDER BY col LIMIT n` still needs a Top-N sort node when the sort key is `col` (the natural-form sort key doesn't match the index expression syntactically), but each comparison in that step now uses the inlined ORE-term path. Verified on the running benches container at 100k rows: `WHERE value < $1 ORDER BY value LIMIT 10` drops from 6.3 s to ~880 ms; the hybrid form `ORDER BY eql_v2.ore_block_u64_8_256(value)` skips the Sort node and lands sub-ms. For the inlining chain to reach index matching, the inner operator backing functions on the `eql_v2.ore_block_u64_8_256` type also needed to be inlinable. `eql_v2.ore_block_u64_8_256_{eq,neq,lt,lte,gt,gte}` were declared `LANGUAGE sql IMMUTABLE STRICT PARALLEL SAFE` (they had defaulted to VOLATILE without annotations) and the file's `!REQUIRE` directives were enabled — those were stale "FILE IS DISABLED" comments; the file was already being concatenated into the release artefact via the build's `find` self-dep, but its function-on-function dependency on `functions.sql` wasn't declared, which broke tsort ordering once another file started requiring it. The same comment was cleaned up on `operator_class.sql`. `tasks/pin_search_path.sql` allowlists the new inlinable overloads (same pattern as the existing `=` / `<>` entries) plus the inner ore_block helpers. `tasks/test/splinter.sh` matches. Scope of breakage: range operators no longer fall through the `eql_v2.compare()` priority list (Block ORE → CLLW u64 → CLLW var → OPE → hmac → literal). Columns carrying only `ore_cllw_u64_8`, `ore_cllw_var_8`, `opf`, or `opv` terms now raise from the `ore_block_u64_8_256` extractor. Callers there must rewrite to the matching extractor form (`WHERE eql_v2.ore_cllw_u64_8(col) < eql_v2.ore_cllw_u64_8($1::jsonb)`, etc.). Existing test coverage for those code paths is marked `#[ignore]` with a pointer to U-005; re-enable once a CASE-style operator body re-introduces broader ORE/OPE support under the inlined operators.

Top-N sorts under `ORDER BY col LIMIT n` still need a Sort node (the natural-form sort key doesn't syntactically match the index expression), but each comparison now uses the inlined ORE-term path rather than a plpgsql `eql_v2.compare()` dispatch. The inner `eql_v2.ore_block_u64_8_256_{eq,neq,lt,lte,gt,gte}` helpers backing the ORE-term type's own operators are now declared `IMMUTABLE STRICT PARALLEL SAFE` and allowlisted in the post-build search-path pin so that the chain inlines cleanly through to index matching. **Behaviour to be aware of:** range queries against columns that carry only `ore_cllw_u64_8` / `ore_cllw_var_8` (CLLW ORE) or OPE terms now raise from the `ore_block_u64_8_256` extractor instead of dispatching through the old `eql_v2.compare()` priority list. Callers in that situation must rewrite to the relevant extractor form (e.g. `WHERE eql_v2.ore_cllw_u64_8(col) < eql_v2.ore_cllw_u64_8($1::jsonb)`) — see [U-005](docs/upgrading/v2.3.md#u-005-range-operators-are-block-ore-only). - **`eql_v2.hmac_256(val jsonb)` and `eql_v2.hmac_256(val eql_v2_encrypted)` are now inlinable SQL.** Both 1-arg overloads flipped from plpgsql-with-RAISE to single-statement SQL returning NULL when `hm` is absent. This restores per-row extractor inlining inside the `=` / `<>` operator bodies. **Behaviour to be aware of:** `WHERE col = $1` on a column lacking `hm` now silently returns zero rows where it previously raised — see the amended [U-002](docs/upgrading/v2.3.md#u-002-equality-and-hashing-require-hmac). The loud RAISE-on-missing-hm path is retained in `eql_v2.hash_encrypted`, so `GROUP BY` / `DISTINCT` / hash joins still surface misconfiguration. ([#205](https://github.com/cipherstash/encrypt-query-language/issues/205)) - **`eql_v2_encrypted = eql_v2_encrypted` is now strictly hmac-based at the root.** Equality requires both sides to carry `hm` (hmac); otherwise the operator returns NULL (and the query returns zero rows). Previously, equality could silently fall through to a `NULL` comparison or to Blake3 on synthetic fixtures. **Behaviour to be aware of:** see [U-002](docs/upgrading/v2.3.md#u-002-equality-and-hashing-require-hmac).

Block ORE is the standard range encoding emitted by the crypto layer for numeric / timestamp / integer columns, so this matches the default configuration most callers run. The narrower contract is also what lets `ORDER BY col LIMIT n` get a fast Top-N sort: with the inlined operator, each comparison reduces to an inlined ORE-term comparison rather than a full plpgsql `compare()` dispatch. + +**Action required.** + +- **Columns configured with `ore` (default for numerics / timestamps / integers)** — no change.

Two paths forward: + - **Preferred:** migrate the column configuration to `ore` (Block ORE) so the natural form works everywhere. + - **If you must keep the existing encoding:** rewrite range queries to the matching extractor form.

These extractor-form predicates engage their own functional indexes on the same expression. +- **Selector-extracted comparisons** (`WHERE e->'selector' < $1`) — same rule applies recursively. If the extracted sub-payload doesn't carry `ob`, rewrite to the extractor matching the sub-payload's term type. + +**Notes for ORDER BY.** Bare-form `ORDER BY col` still needs a Sort node — the natural-form sort key doesn't syntactically match a functional ORE index expression — but the residual Sort step is now fast because each comparison uses the inlined ORE-term path. To skip the Sort node entirely, write the ORDER BY in extractor form: `ORDER BY eql_v2.ore_block_u64_8_256(col)`.

Pinning search_path here breaks the second inlining layer and reverts bare-form `WHERE col ~~ val` to seq scan. function_search_path_mutable eql_v2 ilike function LIKE/ILIKE inlining (#201): same rationale as eql_v2.like — the eql_v2."~~*" operator inlines through eql_v2.ilike to the bloom_filter containment form. diff --git a/tests/sqlx/tests/comparison_tests.rs b/tests/sqlx/tests/comparison_tests.rs index a2277cc5..ea627eae 100644 --- a/tests/sqlx/tests/comparison_tests.rs +++ b/tests/sqlx/tests/comparison_tests.rs @@ -4,8 +4,8 @@ use anyhow::{Context, Result}; use eql_tests::{ - get_ore_encrypted, get_ore_encrypted_as_jsonb, get_ste_vec_selector_term, QueryAssertion, - Selectors, + assert_uses_index, get_ore_encrypted, get_ore_encrypted_as_jsonb, get_ste_vec_selector_term, + QueryAssertion, Selectors, }; use sqlx::{PgPool, Row}; @@ -319,6 +319,7 @@ async fn greater_than_or_equal_jsonb_gte_encrypted(pool: PgPool) -> Result<()> { // Covers ore_cllw_u64_8 and ore_cllw_var_8 index types with fallback behavior #[sqlx::test] +#[ignore = "Breaking with range-operator inlining: < / <= / > / >= on eql_v2_encrypted now reduce to ore_block term comparison (raises on missing ob).

Customers re-encrypt their data as part ### Deprecated - **Operator-class indexes (`CREATE INDEX … (col eql_v2.encrypted_operator_class)`) are discouraged for the equality / `LIKE` query path.** They will continue to function for the lifetime of `2.x` and are not slated for removal in this minor. Functional indexes (`eql_v2.hmac_256(col)`, `eql_v2.bloom_filter(col)`, `eql_v2.ste_vec(col)`) are now the canonical path because they (a) work on Supabase and managed Postgres without superuser, (b) avoid the btree row-size limit (`index row size N exceeds btree version 4 maximum 2704`) that opclass indexes hit on full-payload encryption, and (c) give the planner a structurally matchable extractor. The narrow exception is `ORDER BY` over Block ORE columns, where a custom comparator is strictly required — keep opclass indexes on those columns. See [U-001](docs/upgrading/v2.3.md#u-001-functional-indexes-as-the-canonical-recipe). +- **`eql_v2.lt`, `eql_v2.lte`, `eql_v2.gt`, `eql_v2.gte` are deprecated and slated for removal in EQL 3.0.** These plpgsql helpers used to back the `<` / `<=` / `>` / `>=` operators; after the range-operator inlining ([U-005](docs/upgrading/v2.3.md#u-005-range-operators-are-block-ore-only)) the operators bypass them entirely and inline an `ore_block_u64_8_256` comparison directly. The helpers still walk `eql_v2.compare`'s priority list (ore_block → ore_cllw_u64 → ore_cllw_var → ope), so on `ore_cllw_*` / OPE-only columns they will return a Boolean where the matching operator now raises — same name, divergent contract. Callers invoking them directly should switch to the operator form for `ore` columns, or to the relevant extractor form (e.g. `eql_v2.ore_cllw_u64_8(col) < eql_v2.ore_cllw_u64_8($1::jsonb)`) for `ore_cllw_*` / OPE columns.
