075eabc902441874ead405d1358ef8baaa079edd Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Wed, 29 Apr 2026 12:34:53 +0800 Subject: [PATCH 06/17] refactor(postgres): rewrite hstore module with Expression/Dialect architecture Replace raw string returns with Expression objects (FunctionCall, BinaryExpression) in hstore function factories. Add PostgresHstore dataclass, PostgresHstoreAdapter, and simplify hstore extension mixin to only keep supports_*() methods.

0bccf77ebc29093c87f5737e7e08fcb7912d7f70 Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Wed, 29 Apr 2026 12:35:07 +0800 Subject: [PATCH 07/17] refactor(postgres): add extension-aware function version system Replace flat _POSTGRES_FUNCTION_VERSIONS dict with categorized FunctionVersionRequirement definitions in function_versions.py. Functions from extensions (hstore, uuid-ossp, pgvector, PostGIS) now require extension installation check via introspect_and_adapt(). Key changes: - FunctionVersionRequirement: structured version req with extension awareness - FunctionSupportInfo: detailed support status with reason for unavailability - supports_functions() returns Dict[str, FunctionSupportInfo] - Extension functions return False when _extensions not probed (no guessing) - _POSTGRES_FUNCTION_VERSIONS moved to function_versions.py, 15 categories Co-Authored-By: Claude Opus 4.6 --- .../backend/impl/postgres/dialect.py | 320 +++++-------- .../impl/postgres/function_versions.py | 357 ++++++++++++++ .../postgres/test_function_versions.py | 435 ++++++++++++++++++ 3 files changed, 901 insertions(+), 211 deletions(-) create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/function_versions.py create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/postgres/test_function_versions.py diff --git a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py index a874bda6..7b96717d 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py @@ -1335,233 +1335,94 @@ def supports_drop_trigger(self) -> bool: # PostgreSQL function version support: function_name -> (min_version, max_version) # min_version: minimum supported version (inclusive), None = all versions -

From 8a27d7f77acae48673ec0560309981e531664b6d Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Wed, 29 Apr 2026 17:15:43 +0800 Subject: [PATCH 09/17] refactor(postgres): align Expression-Dialect architecture across all function modules Implement all 6 phases of the expression-dialect alignment plan: Phase 1: Rewrite core native type function factories (geometric, bit_string, enum, array, json, text_search, xml, network) to return Expression objects instead of raw SQL strings. Phase 2-3: Create new function factory modules for all extension types (pgcrypto, ltree, pg_trgm, fuzzystrmatch, earthdistance, intarray, cube, citext, pg_stat_statements, postgis_raster, pglogical, pgrouting, tablefunc, pg_cron, pgaudit, hypopg, pg_surgery, pg_walinspect, address_standardizer, pg_partman, pg_repack, orafce) and add data_type function factories (xid8_literal, array_literal). Phase 4: Migrate multirange/data_type format_* methods from mixins to function factories, retaining only supports_* and DDL methods in mixins. Phase 5: Update all tests to use Expression-based assertions (to_sql(), isinstance checks) instead of raw string comparison. Phase 6: Add 4 new protocol definitions (PostgresFullTextSearchSupport, PostgresRangeTypeSupport, PostgresJSONBEnhancedSupport, PostgresArrayEnhancedSupport) with corresponding supports_* methods in PostgresDialect.

TestProtocolMethodSignatureConformance: verifies method signatures on PostgresDialect match Protocol declarations - TestProtocolMixinForwardCoverage: verifies Protocol-declared methods exist in corresponding Mixins (42 Protocol-Mixin pairs) - TestProtocolMixinReverseCoverage: verifies Mixin-implemented methods are declared in corresponding Protocols Also fix protocol implementation gaps discovered by the tests: New Mixins (5): - PostgresFullTextSearchMixin: 4 methods migrated from Dialect - PostgresRangeTypeMixin: 4 methods migrated from Dialect - PostgresJSONBEnhancedMixin: 5 methods migrated + 1 new (supports_jsonb_subscript) - PostgresArrayEnhancedMixin: 5 methods migrated + 1 new (supports_domain_arrays) - PostgresParallelQueryMixin: 6 new methods (all previously missing) Protocol declarations completed (8): - PostgresExtensionSupport: +2 methods - PostgresPartitionSupport: +1 method - PostgresIndexSupport: +6 methods - PostgresDataTypeSupport: +1 method - PostgresMultirangeSupport: +2 methods - PostgresEnumTypeSupport: +10 methods - PostgresQueryOptimizationSupport: +6 methods - PostgresSQLSyntaxSupport: +9 methods Upgrade get_all_protocol_methods() to walk MRO for Python < 3.12, and add get_own_protocol_methods() for forward coverage testing.

Rename PostgresGeometryAdapter (postgis) to PostgresPostGISAdapter to avoid name collision with geometric adapter (F811) - Rename orafce trunc/round to orafce_trunc/orafce_round to avoid collision with math_enhanced module (F811) - Add TYPE_CHECKING imports for FunctionSupportInfo and FunctionVersionRequirement in dialect.py (F821) - Remove unused imports: List, Optional, Dict, re, field (F401) - Remove unused variable assignment for provider in cli/info.py (F841) - Add `from None` to raise inside except in types/postgis.py (B904) - Fix f-string without placeholders in examples/types/uuid.py (F541) - Break long lines across adapters, cli, introspection, functions, mixins, and protocols modules (E501) -

Convert raw SQL strings in fixtures and test methods to expression objects (CreateTableExpression, InsertExpression, QueryExpression, FunctionCall, etc.). Key changes: - Add async_ensure_extension_installed to test utils - Add async_postgres_backend_single fixture to conftest - Add 29 async test classes with _async table suffix convention - Replace raw SQL with expression objects across all integration tests - Use Literal.cast("type") for PostgreSQL type casts (cube, hstore, ltree, vector, uuid, integer[], geography) instead of RawSQLExpression - Use Subquery wrapper for ComparisonPredicate aliasing - Use specific exception types (IntegrityError, DatabaseError) instead of bare Exception in pytest.raises - Fix earth_distance() assertion (returns meters, not miles) - Fix hypopg_estimate_size assertion (maps to hypopg_relation_size) Remaining RawSQLExpression usage (with TODO comments): - COUNT(*) where Literal("*") gets parameterized - PostgreSQL operators with aliases where ComparisonPredicate lacks .as_() - Index opclass specifications (no structural expression support) All 316 tests pass, 13 skipped (extensions not available/permissions).
