From 0320356afc553a53ab82df1f65ff89c0666b5b49 Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Sun, 11 Oct 2026 23:53:30 +0800 Subject: [PATCH 01/77] fix(types): refuse a non-boolean unsigned when the type is rendered The shape check now lives where the flag has to be honoured rather than where it is declared, so a value that would silently render the wrong DDL is named instead. The attribute is read directly: whether the field exists is settled by the class, so probing for it with a default would only turn a wrong class into a quiet signed column. CI installs the core library from fix/column-constraint-gates so this backend runs against the branch it depends on. --- .github/workflows/test.yml | 8 +- .../mixins/types/data_type_formatting.py | 32 ++++++- .../types/test_postgres_type_protocol.py | 88 +++++++++++++++++-- 3 files changed, 116 insertions(+), 12 deletions(-) diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index 1069bd81..62168d60 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -68,7 +68,7 @@ jobs: - name: Install activerecord and testsuite run: | - pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@release/v1.0.0.dev30" + pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@fix/column-constraint-gates" pip install "rhosocial-activerecord-testsuite @ git+https://github.com/rhosocial/python-activerecord-testsuite.git@release/v1.0.0.dev17" - name: Create postgres scenario config @@ -283,7 +283,7 @@ jobs: - name: Install activerecord and testsuite run: | - pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@release/v1.0.0.dev30" + pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@fix/column-constraint-gates" pip install "rhosocial-activerecord-testsuite @ git+https://github.com/rhosocial/python-activerecord-testsuite.git@release/v1.0.0.dev17" - name: Create postgres scenario config @@ -395,7 +395,7 @@ jobs: - name: Install activerecord and testsuite run: | - pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@release/v1.0.0.dev30" + pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@fix/column-constraint-gates" pip install "rhosocial-activerecord-testsuite @ git+https://github.com/rhosocial/python-activerecord-testsuite.git@release/v1.0.0.dev17" - name: Create postgres scenario config @@ -493,7 +493,7 @@ jobs: - name: Install activerecord and testsuite run: | - pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@release/v1.0.0.dev30" + pip install "rhosocial-activerecord @ git+https://github.com/rhosocial/python-activerecord.git@fix/column-constraint-gates" pip install "rhosocial-activerecord-testsuite @ git+https://github.com/rhosocial/python-activerecord-testsuite.git@release/v1.0.0.dev17" - name: Create postgres scenario config diff --git a/src/rhosocial/activerecord/backend/impl/postgres/mixins/types/data_type_formatting.py b/src/rhosocial/activerecord/backend/impl/postgres/mixins/types/data_type_formatting.py index 32b56930..2367731d 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/mixins/types/data_type_formatting.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/mixins/types/data_type_formatting.py @@ -277,7 +277,22 @@ def _refuse_unsigned_integer( dropping the *concept* here; what would be lost is the caller's statement that this column holds no negative value, and that belongs in a ``CHECK`` constraint. + + The shape of ``unsigned`` is checked here, at the rendering end, rather + than in the expression's constructor: an expression collects its + parameters without judging them, because only the formatter knows which + backend will have to honour this flag.

Each rendered byte-identical SQL to the core class it derived from, and DataType.__eq__ is type(self) is type(other) -- so a class differing only in its name made a declaration and the catalog row it produced compare unequal, and the differ reported an unchanged column as changed. Unlike Firebird's, these were not unreachable: parse_type answered BYTEA, BLOB, UUID and XML with the Postgres class rather than the concept, so the breakage was live in both directions. It now answers with the core class, which is what makes the round trip close -- each of the three comes back to itself, where before it came back as a different class than it started as. The round-trip test's WIDENING_ANSWERS loses three entries for that reason. Those were not widenings: they recorded that parse_type disagreed with the declaration, which is the defect. --- .../examples/sqlxml/standard_expressions.py | 7 +-- .../impl/postgres/expression/__init__.py | 6 --- .../backend/impl/postgres/expression/types.py | 49 +------------------ .../mixins/types/data_type_formatting.py | 36 ++------------ tests/providers/fixtures/basic.py | 10 ++-- .../extensions/test_pgcrypto_integration.py | 6 +-- .../extensions/test_uuid_ossp_integration.py | 12 ++--- .../backend/postgres/test_cast_integration.py | 7 ++- .../postgres/test_ddl_source_collection.py | 8 +-- .../types/test_data_type_formatting.py | 25 +++++----- .../backend/types/test_expression_types.py | 9 ++-- .../types/test_postgres_type_protocol.py | 16 +++--- 12 files changed, 49 insertions(+), 142 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/examples/sqlxml/standard_expressions.py b/src/rhosocial/activerecord/backend/impl/postgres/examples/sqlxml/standard_expressions.py index 4c5a4234..b43f88a3 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/examples/sqlxml/standard_expressions.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/examples/sqlxml/standard_expressions.py @@ -44,10 +44,7 @@ from rhosocial.activerecord.backend.impl.postgres.backend import PostgresBackend from rhosocial.activerecord.backend.impl.postgres.config import PostgresConnectionConfig from rhosocial.activerecord.backend.impl.postgres.dialect import PostgresDialect -from rhosocial.activerecord.backend.expression.types import TextType -from rhosocial.activerecord.backend.impl.postgres.expression.types import ( - PostgresXMLType, -) +from rhosocial.activerecord.backend.expression.types import TextType, XmlType SQLParam = Optional[Union[str, int, float, bool]] SQLParams = Tuple[SQLParam, ...] @@ -80,7 +77,7 @@ def text_literal(dialect: PostgresDialect, value: str) -> Literal: def xml_literal(dialect: PostgresDialect, value: str) -> Literal: expr = Literal(dialect, value) - expr.cast(PostgresXMLType(dialect)) + expr.cast(XmlType(dialect)) return expr diff --git a/src/rhosocial/activerecord/backend/impl/postgres/expression/__init__.py b/src/rhosocial/activerecord/backend/impl/postgres/expression/__init__.py index 95c744bc..5cef8991 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/expression/__init__.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/expression/__init__.py @@ -112,7 +112,6 @@ PostgresBigSerialType, PostgresBitType, PostgresBoxType, - PostgresByteaType, PostgresCIDType, PostgresCircleType, PostgresDateMultirangeType, @@ -149,14 +148,12 @@ PostgresTsRangeType, PostgresTsTzMultirangeType, PostgresTsTzRangeType, - PostgresUUIDType, PostgresVarBitType, PostgresVectorType, PostgresHalfvecType, PostgresSparsevecType, PostgresXID8Type, PostgresXIDType, - PostgresXMLType, PostgresCidrType, ) from .registry import register_postgres_ddl_expressions @@ -261,7 +258,6 @@ "PostgresBigSerialType", "PostgresBitType", "PostgresBoxType", - "PostgresByteaType", "PostgresCIDType", "PostgresCircleType", "PostgresDateMultirangeType", @@ -298,14 +294,12 @@ "PostgresTsRangeType", "PostgresTsTzMultirangeType", "PostgresTsTzRangeType", - "PostgresUUIDType", "PostgresVarBitType", "PostgresVectorType", "PostgresHalfvecType", "PostgresSparsevecType", "PostgresXID8Type", "PostgresXIDType", - "PostgresXMLType", "PostgresCidrType", "register_postgres_ddl_expressions", ] diff --git a/src/rhosocial/activerecord/backend/impl/postgres/expression/types.py b/src/rhosocial/activerecord/backend/impl/postgres/expression/types.py index 026b190c..3aafcff6 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/expression/types.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/expression/types.py @@ -23,13 +23,10 @@ ArrayType, EnumType, BigIntType, - BlobType, DataType, IntegerType, SmallIntType, TextType, - UUIDType, - XmlType, ) if TYPE_CHECKING: @@ -40,21 +37,8 @@ # Binary data: BYTEA # --------------------------------------------------------------------------- -class PostgresByteaType(BlobType): - """PostgreSQL ``BYTEA`` — variable-length binary string. - - PostgreSQL's own name for the concept core calls ``BlobType``; ``BYTEA`` is - in that concept's ``SPELLINGS`` list, so the storage is identical and only - the written form differs. - """ - - name = "postgres_bytea" -# --------------------------------------------------------------------------- -# Serial (auto-increment) types -# --------------------------------------------------------------------------- - class PostgresSmallSerialType(SmallIntType): """PostgreSQL ``SMALLSERIAL`` — auto-incrementing SMALLINT (2 bytes). @@ -183,40 +167,9 @@ def __init__( PARAMETERS = ("type_name", "schema", "values",) -class PostgresUUIDType(UUIDType): - """PostgreSQL ``UUID`` — universally unique identifier. - - PostgreSQL is the reference implementation for this concept: 128 random - bits, stored in the order PostgreSQL documents.

Constraint surfaces follow in the next commit -- see below. Migration surface (src + tests + docs, 215 files): W2, 57 statement-level classes -> *Statement (core 34e1fb45). The largest here: QueryExpression->QueryStatement 688, CreateTableExpression ->CreateTableStatement 415, DropTableExpression->DropTableStatement 309, InsertExpression->InsertStatement 283, CreateIndexExpression ->CreateIndexStatement 86, UpdateExpression->UpdateStatement 39, RefreshMaterializedViewExpression->RefreshMaterializedViewStatement 36, TruncateExpression->TruncateStatement 36, CreateTableLikeExpression 36, CreateMaterializedViewExpression 33, DropMaterializedViewExpression 32, and the rest. W3a, predicate/clause/match nodes (core 890aaaa3): ILIKEExpression ->ILikePredicate 29, FulltextMatchExpression->FulltextMatch 13. W3b, value/function/introspection families (core 5dc64fd5): WildcardExpression->Wildcard 30, SQLValue 18, QualifiedIdentifier 10, JSONTextValue 10, Introspection*Info 53, CastFunction 8, JSONDocumentValue 8, CaseFunction 3, CollateFunction 3, UUIDCastFunction 3. UUIDCastExpression->UUIDCastFunction is the one mapping the wave guide does not list; verified against the core commit. W1, CTE family (core 683a183e): CTEExpression->CTEClause 24, WithQueryExpression->WithStatement 20, and the call-site keyword main_query=->query= 13 (every occurrence in this repo was an argument of WithQueryExpression). S1-c, PASSING: no change needed -- this backend constructs the XML expressions through the xmlexists()/xmlquery() factories, whose passing= signature is unchanged. Override points renamed (functional; not renaming would drop the override): format_ilike_predicate 5, format_begin_transaction_statement 2, format_cte_clause 1 (mixins/cte.py comment). Behaviour: none. Every edit is a name; no SQL spelling moved. Note: the constraint surfaces still reference the enums core's S3 removed (ColumnConstraintType/TableConstraintType), so this commit is an expected red window -- the whole package fails to import until the next commit. Wave 2 migrates the construction sites onto the branch nodes. Verification: - import smoke over the postgres backend modules: 147 import clean, 13 fail and all 13 share the single deleted-symbol cause (cannot import name 'TableConstraintType') raised from expression/ddl/exclude_constraint.py, which is a wave-2 surface. - python -m compileall src tests docs: exit 0 (only the two pre-existing SyntaxWarnings in docs/examples/chapter_02_connection_pool). - ruff check on the 215 changed files: identical to the HEAD baseline for the same file set (one pre-existing E501 in test_insert_on_conflict_clauses.py resolved by the rename). No new finding outside mixins/ddl/constraint.py, whose five F821s are the known draft middle state. --- docs/en_US/ddl/README.md | 20 +- docs/en_US/ddl/materialized_view.md | 10 +-

This commit migrates every construction site, every override and every assertion in the package onto that shape, and absorbs the mechanical part of the B-series draft that was sitting uncommitted in the worktree. Construction sites migrated (src + tests + docs, 96 files): ColumnPrimaryKeyConstraint 147 ColumnDefaultConstraint 39 ColumnNotNullConstraint 131 ColumnForeignKeyConstraint 8 ColumnNullableConstraint 4 ColumnUniqueConstraint 2 ColumnCheckConstraint 1 TablePrimaryKeyConstraint 7 TableForeignKeyConstraint 2 TableUniqueConstraint 1 TableCheckConstraint 1 Call shape: ``ColumnConstraint(dialect, ColumnConstraintType.NOT_NULL)`` becomes ``ColumnConstraint(dialect, branch=ColumnNotNullConstraint(dialect))``. The old keyword-per-field form is gone with it -- ``default_value=`` is now the branch's positional ``value``, ``foreign_key_reference=`` the branch's ``references`` pair, ``check_condition=`` the CHECK branch's ``condition``. GeneratedColumnExpression is deleted from core, so its one call site became ``ColumnGeneratedConstraint``. EXCLUDE. PostgreSQL's grammar is richer than core's ``TableExcludeConstraint`` (one operator per element plus a partial predicate), so the branch is ``PostgresExcludeBranch`` and ``PostgresExcludeConstraint`` becomes the production-level sugar over it -- the same shape core's own ``ForeignKeyConstraint`` has, so the 20-odd call sites keep working unchanged. ``_format_exclude_constraint`` (private, production-and-body in one) became the public ``format_table_exclude_constraint``, which now renders the body only: the ``CONSTRAINT `` prefix and the traits are the production's and are rendered by ``format_table_constraint``, where the grammar puts them. Override points: - ``format_table_constraint`` -- narrows the enforcement trait to CHECK and FOREIGN KEY (measured 0A000 for PRIMARY KEY/UNIQUE) before delegating. - ``format_alter_constraint_action`` -- gates the verb on the measured per-kind boundary (FOREIGN KEY from 18, CHECK from 19). - ``format_column_constraint`` -- refuses the enforcement trait outright. - ``format_add_table_constraint_action`` -- **removed**. Core already renders the production, dispatches to the branch (so EXCLUDE gets its own formatter) and appends NOT VALID; the only PostgreSQL-specific judgement was the enforcement one and it lives in format_table_constraint. This is the narrowing the guide asks for: fewer overrides, not more. - ``_format_constraint_enforcement`` is deliberately NOT overridden. It is shared by the column-level trait renderer and the table-level one, so an override there would have to tell the two families apart by hand; the public column-level seam says which family it is. Behaviour changes (all measured, all previously silent or unimplemented): - ``[NOT] ENFORCED`` on a column constraint now refuses. Measured 42601 ``misplaced NOT ENFORCED clause`` for every kind on 18/19. - A string or enum where a branch class belongs is a TypeError at construction, not a tag that happens to be accepted. - ``AlterConstraint`` takes ``constraint_kind=`` (branch class or spelling) instead of ``constraint_type=``. - EXCLUDE refuses DEFERRABLE/INITIALLY/ENFORCED: core's branch whitelist does not list it and this backend does not widen it, so the request cannot be written. ``PostgresExcludeConstraint(..., enforced=True)`` is a TypeError. Serialization. ``PostgresAlterConstraint`` gains a ``constraint_kind`` view: core's ``AlterConstraint`` declares ``constraint_kind`` but stores it as ``constraint_branch``, and ``get_params()`` -- the single serialization path -- resolves parameters by name, so without the view the kind is dropped and the action cannot be rebuilt. The view yields the *spelling*, because a class object is not encodable by any of the three channels. Wildcard. ``functions/vector_search.py`` took ``Wildcard`` from core, which the split removed, and the package would not import without it. That one import and its one call site move to ``AllColumnsWildcard`` (a select-list position) here; the rest of the split is the next commit. Tests rewritten to the new API: the per-kind enforcement probe tests became probe-version-gate plus formatter-behaviour; the column-level "renders successfully" assertion became a refusal (the draft contradicted its own docstring evidence -- pattern 10 of the ten reconciliation rules says the assertion moves, not the measurement); the EXCLUDE deferral pair guards became construction-refusal tests with the measurement quoted; ``format_default_ constraint`` became ``format_column_default_constraint`` on the branch. Verification: - import smoke over every module in the backend package: 346 imported, 0 failures (was 147 ok / 13 failing on the deleted enums at the previous commit). - targeted constraint suites, exit 0: tests/.../postgres/test_ddl_alter_config.py tests/.../postgres/test_postgres_constraint_capabilities.py tests/.../test_postgres_dialect_security.py tests/.../test_clause_pair_guard.py tests/.../postgres/test_ddl_source_collection.py tests/.../test_expression_roundtrip_all.py (472 passed, 3 skipped) - ruff check on the 102 changed files: one finding below the HEAD baseline for the same file set and no new class of finding. The one new F821 is one more reference to the already-undefined `dialect` in tests/.../extensions/test_pgvector_integration.py, a file with six such findings at HEAD. Not green, and not this repository's to fix: the testsuite's shared feature/ddl contract cannot run, because python-activerecord-testsuite@fix/column-constraint-gates (a57f266) still imports the deleted ``ColumnConstraintType`` in feature/ddl/{fixtures/models,test_derivation,test_derivation_async, test_ddl_source_contract}.py. That is WP-T/S4 work in the testsuite repo. --- docs/examples/chapter_04_ddl/ddl.py | 9 +- .../examples/connection/quickstart.py | 11 +- .../impl/postgres/examples/ddl/alter_table.py | 7 +-

A probe answers one question -- "is this capability family present on this server" -- and the kind is not part of that question; a parameterised probe has two call shapes depending on its own signature, which is how the draft ended up with a switch whose kind-less answer (``False`` on 19!) contradicted its kinded one. Both now answer the version gate they were always answering: supports_constraint_enforced() version >= 18 (170011 / 180006 / 190000) supports_alter_constraint_enforced() version >= 18 The per-kind answers did not disappear; they moved to the place that can see the kind, which is the branch class: _require_constraint_enforced(branch) TableCheckConstraint / TableForeignKeyConstraint and version >= 18; anything else refuses _require_enforceable_constraint(branch) TableForeignKeyConstraint from 18, TableCheckConstraint from 19 Both raise TypeError on a non-branch argument (pattern 4: a spelling is a type question) and UnsupportedFeatureError naming the SQL spelling -- ``CHECK NOT ENFORCED``, ``ALTER CONSTRAINT CHECK NOT ENFORCED`` -- with the message the other ten backends use (pattern 7). **Narrowing seams.** No private formatter was added, and the shared private hook was left alone: - column-level refusal -> the public ``format_column_constraint``, before delegation. ``_format_constraint_enforcement`` is shared by the column-level trait renderer and the table-level one, so an override there would have to tell the two families apart by hand; overriding the column seam makes the family the override's own business. - table-level per-kind refusal -> the public ``format_table_constraint``. - ALTER per-kind version -> the public ``format_alter_constraint_action``. - EXCLUDE -> the public ``format_table_exclude_constraint``. **Local declaration discipline** (pattern 5), now enforced rather than asserted in prose. New in test_postgres_constraint_capabilities.py: - ``test_resolved_switch_is_owned_by_this_backend`` -- for every switch this backend relies on, the first class in the dialect's MRO that has the name in ``__dict__`` must be inside this package. A core default that reaches the MRO first would otherwise answer instead of the measured value, silently. - ``test_the_declaring_class_is_a_postgres_mixin`` -- the answering class is a PostgreSQL one, whatever mixin owns it. (Not every switch is on ``PostgresConstraintMixin``: ``supports_drop_constraint_if_exists`` is declared by the ALTER COLUMN modifier, which reaches the MRO first. The guard is therefore package-scoped, which is what the rule actually says.) - ``test_probes_take_no_argument`` -- ``(self)`` and nothing else, checked on the bound method so a defaulted parameter cannot slip back in. - ``test_version_gate_matches_the_measurement`` -- the 17/18/19 boundary. - ``test_docstring_quotes_the_measurement`` -- pattern 6, made mechanical: a switch docstring must contain a SQLSTATE, a server version, or the server's own "accepted" verdict. A docstring that stops quoting its measurement fails here instead of quietly becoming a guess with a name. **Docstrings.** The two "KNOWN DEFECT (core S3, deliberately not fixed here)" paragraphs are gone -- the defect they described was core's ``inspect.signature`` sniffing of a parameterised probe, which core removed. Each probe now points at where its per-kind half lives.

The two answer different questions -- ``COUNT(*)`` counts rows, ``t.*`` expands columns -- and only the aggregate's contract admits the second. Call sites migrated by position, not by name: select-list / RETURNING (13) Wildcard -> AllColumnsWildcard COUNT argument (3) Wildcard -> RowCountWildcard examples/ddl/materialized_view.py, examples/query/pagination.py, test_partition_operations.py One qualified form changed shape as well as name: ``Wildcard(dialect, table="users", schema_name="app")`` became ``AllColumnsWildcard(dialect, relation=NamedRelationRef(...))``. The qualification rides the relation object because the name to render is the name the query uses, and that is what the reference holds. Backend-specific: ``PostgreSQLRowCountWildcard``. ``COUNT(t.*)`` counts the non-NULL rows of one relation rather than the rows of the join -- under a LEFT JOIN the two answer differently -- so it is a separate node and not a flag. Core's ``RowCountWildcard`` accepts no relation by contract, so the derivation lives here and the override is ``format_row_count_wildcard``. The override tests the class rather than probing for a missing attribute: core's node has no ``relation`` at all, and asking for one anyway is the reflection rule 9.8 forbids. Anything that is not the qualified form renders the bare asterisk, so core's ``COUNT(*)`` path is untouched. No ``format_wildcard`` override existed here, so none needed renaming. Tests: ``test_schema_namespace.py`` gains the two wildcard contracts -- bare ``COUNT(*)`` stays bare, and ``COUNT(t.*)`` renders the alias the query uses.

Behaviour tightening: an object that reaches the ALTER DOMAIN / ALTER TYPE / MATERIALIZED VIEW fall-throughs without the declared action_kind, or a JSONPath node without mode, now fails with AttributeError instead of rendering the class name into the refusal message. No in-repo caller hit the removed branches. Also dropped two dead imports in mixins/ddl/type.py (SchemaObject, shadowed typing.Type) so the touched file is ruff-clean; both were flagged on HEAD already.

The backend-side registration module this repository kept for the old FQN index is therefore dead code, and after that core commit it broke the whole backend import chain (dialect -> mixins -> expression/__init__ -> registry). Removed expression/registry.py and its import-time call from expression/__init__.py, following the shape mysql already converged to (no backend-side registration module; whoever reads an artifact back enters the kinds it names, which is the core commit's own answer to "who registers a backend's kinds"). Same core commit, test side: the two TYPE-definition round-trip tests in postgres/test_ddl_objects.py deserialize PostgreSQL-specific kinds, which the framework whitelist does not carry. The test module now registers exactly what it reads back -- the two definition classes, the composite attribute dataclass and the UNSET sentinel enum -- into the default registry at import time. Also dropped the pre-existing unused Literal import so the touched file is ruff-clean. Behaviour change: PostgreSQL-specific expression classes are no longer entered into the (removed) global deserialization index at import time. Serializing them was never affected - a node carries its own kind. Test evidence (central venv, PYTHONPATH=src;tests): - import smoke `from ...postgres.dialect import PostgresDialect` exit 0 (raised ImportError before the removal); - postgres/test_ddl_objects.py exit 0 (the two round-trip tests failed with "kind ... is not in the kind whitelist" before the registration); -

From 32dc4c73226e489ec1e1f7c5a17f05adb1e614e7 Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Sun, 18 Oct 2026 08:39:14 +0800 Subject: [PATCH 15/77] feat(postgres): adopt the typed value nodes with PostgreSQL literal spellings Wire the core TypedValueMixin (473b8e37 + 5ba491d5 + 1549380b) into the dialect: a new PostgresTypedValueMixin rides ahead of it in the base list, so the twelve typed value nodes resolve per kind while exactly the three PostgreSQL spells differently stay backend-owned (spec 4.4 tier 2). Overridden, with the inline (DDL-position) spellings: - format_binary_value: '\x0102'::bytea -- the hex bytea literal, rendered from the bytes the node holds. Hex input needs PostgreSQL 9.0+; every declared version satisfies that. - format_uuid_value: '...'::uuid -- the quoted canonical form plus the cast, the same shape the dialect's UUID_SQL table spells for the UUID constants (mixins/uuid.py). - format_interval_value: INTERVAL '...' with the span decomposed into days / hours / minutes / seconds, every emitted component carrying the sign. Per-component signs are a measured answer, not a preference: live servers parse INTERVAL '-2 days 03:04:05.000006' as minus two days PLUS 03:04:05 (the leading minus does not carry into the time part), so signing each component is the only faithful spelling. A zero span renders INTERVAL '0 seconds'; microseconds render as a six-digit fraction when present. Tier-1 audit: PostgreSQL agrees with the base defaults everywhere -- TRUE / FALSE booleans, numeric text, quoted ISO dates and times, doubled-quote strings -- so no tier-1 method is overridden and no literal logic copied. The data position binds bytes / uuid.UUID / timedelta through the core _bind_value; the psycopg placeholder is left to the dialect base. Measured live 2026-10-17/18 against servers reporting 13.23, 17.11, 18.6 and 19beta4 (Debian): all four accept the three spellings, and a CREATE TABLE whose bytea / uuid / interval columns carry them as DEFAULT values round-trips exactly through INSERT ... DEFAULT VALUES + SELECT on all four (oldest scenario configured as "postgres_9" measured 13.23). New test file postgres/test_typed_values.py: MRO pin (the three methods resolve on the postgres mixin), data-position bindings for every overridden kind plus tier-1 passthrough, exact DDL-position texts for binary (bytes and bytearray), uuid and seven interval shapes, and live sentinel + column-default read-backs on every configured scenario. Test evidence (central venv, PYTHONPATH=src;tests): - postgres/test_typed_values.py: 61 executions exit 0 (17 offline + 4 live across 11 configured scenarios); - feature/backend -k "typed or literal" (5 wave-4-scope collection breakages from core's in-flight commits ignored, see report): exit 0; - ruff clean on every touched file (also fixed the pre-existing missing PostgresObjectNameMixin __all__ entry flagged in mixins/__init__.py). Open items, not this wave: the roundtrip matrix file still imports the retired serialization API and the testsuite expression helper -- wave 4 reconciles it against the core HEAD of that day, mirroring mysql's vendored harness. --- .../backend/impl/postgres/dialect.py | 11 + .../backend/impl/postgres/mixins/__init__.py | 3 + .../impl/postgres/mixins/typed_value.py | 137 ++++++++ .../backend/postgres/test_typed_values.py | 292 ++++++++++++++++++ 4 files changed, 443 insertions(+) create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/mixins/typed_value.py create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/postgres/test_typed_values.py diff --git a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py index 51045352..1349230b 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py @@ -80,6 +80,10 @@ TransactionControlMixin, UserDefinedTypeMixin, DomainMixin, + # Value literals: the tier-1 rendering lives on the core mixin; the + # tier-2 spellings PostgreSQL differs on live on this backend's mixin, + # which the base list composes ahead of this one. + TypedValueMixin, ) from rhosocial.activerecord.backend.dialect.protocols import ( AlterDatabaseSupport, @@ -260,6 +264,7 @@ PostgresAutoIncrementMixin, PostgresExpressionMixin, PostgresFunctionMixin, + PostgresTypedValueMixin, ) from .protocols.ddl.type import PostgresTypeSupport @@ -555,6 +560,12 @@ class PostgresDialect( PostgresExtendedStatisticsMixin, PostgresStoredProcedureMixin, PostgresAdvisoryLockMixin, + # Value literals: PostgreSQL's tier-2 spellings ahead of the core's + # tier-1 rendering.

The semantic sites in this repository that the core has classed now build (or delegate to) those classed nodes; the ~295 remaining FunctionCall sites spell extension-specific functions the core has not classed (postgis, hstore, pgcrypto, ll_to_earth, ...) and stay generic on purpose -- FunctionCall is the UDF node, and migrating an unclassed concept would chase the moving target the wave guide forbids. Migrated (functions/math_enhanced.py, 9 of 11 factories): - round_ / trunc -> RoundFunction / TruncateFunction via for_operand, preserving the always-rendered precision operand (default 0 binds a literal, an expression-valued precision passes through -- the previous factory wrapped a Literal in another Literal when handed one) - pow / power -> PowerFunction. pow keeps its name but now writes the canonical POWER: both spellings accepted, measured live 2026-10-18 on 17.11 (POW(2.0,10) and POWER(2.0,10) both answer 1024) - sqrt -> SquareRootFunction, mod -> ModuloFunction, ceil -> CeilFunction, floor -> FloorFunction, avg -> AvgFunction (all render the same text as before) - max_ / min_ stay FunctionCall: GREATEST / LEAST are scalar and unclassed even in the core (its own greatest/least factories also build the generic node); the aggregate Min/MaxFunction are different concepts Spelling override added (mixins/expression.py): - format_truncate_function writes TRUNC. The core node spells the SQL-standard TRUNCATE, which in PostgreSQL is the DDL statement that empties a table; measured live 2026-10-18 on 17.11: TRUNC(3.716, 2) answers 3.71, TRUNCATE(3.716) is refused with UndefinedFunction "function truncate(numeric) does not exist" char_length audit: PostgreSQL uses the core default. The core's format_char_length_function writes LENGTH and deliberately does not read the unit field; live-measured on 17.11, length('hello') = 5 characters against octet_length('hello') = 6 bytes, so PostgreSQL's LENGTH already answers the character question the core spelling assumes -- no override, like oracle / snowflake / bigquery. Leftover: examples/conftest.py described UNION as "using SetOperationStatement"; the class is SetOperation.

PostgreSQL has three: binary, UUID and INTERVAL. The 2026-10-17/18 live measurements behind them (13.23 / 17.11 / 18.6 / 19beta4, CREATE TABLE DEFAULT read back byte-exactly, the per-component interval sign) are carried over unchanged -- an architecture change does not invalidate a measured answer. Literal mixin - mixins/typed_value.py -> mixins/literal.py: PostgresLiteralValueMixin overrides format_literal (bytes -> '\x0102'::bytea, UUID -> '...'::uuid, timedelta -> INTERVAL '...'); everything else defers to super(). - First position in the dialect base list, ahead of SQLDialectBase: a mixin placed after the class it overrides never wins the lookup. - test_typed_values.py -> test_literal_values.py, rewritten around the inline flag. Binding and inline assertions, the tier-1 audit, the base refusal and the live read-backs are all kept. Partition bounds - _inline_partition_expression is gone. Whether a value inlines is the caller's per-node decision, so the pass that copied a bound tree and swapped every Literal for the DDL class is: a bound renders as composed, a literal left binding is refused by name. Three tests that relied on the old lift now say inline=True; one new test pins the refusal. Action renames (guide 10.3, same batch) - AddColumn/DropColumn/AddTableConstraint/DropTableConstraint/AddIndex/ AlterConstraint/ValidateConstraint/AlterColumn/RenameColumn -> *Action, in src, tests and the two schema_diff examples. - The suffix lists in the roundtrip matrix lost the entries that named the removed classes; a suffix matching nothing registers nothing. - examples/ddl/alter_table.py was missing the Table import its own code uses. Plain-JSON artifacts (guide 12.1) - register_dataclass / register_enum are gone from the core registry, and an artifact carries no class path any more, so the two PostgreSQL parameters that were host objects had to become values: * PostgresCompositeTypeAttribute gains as_params/from_params and PostgresCompositeTypeDefinition overrides get_params to emit the attribute as a mapping. The constructor takes either form and stores the dataclass (entry wide, storage normalized). * _UnsetValue is now (str, Enum) with __str__ = str.__str__, so the "clause not supplied" sentinel travels as the text "UNSET"; the constructor normalises it back, without which every deserialized base TYPE would claim a DEFAULT it never declared.

Date: Tue, 20 Oct 2026 00:07:05 +0800 Subject: [PATCH 18/77] refactor(postgres): audit the kinds this backend overrides and owns Sweep the backend's expression package against the org rule that a kind core has already issued may only be overridden in rendering, never redeclared as a node class, and that a kind core does not have is the backend's own -- named with the backend identifier in front. Found and fixed, per the lineage script (core 357 kinds; backend 167 -> 161 custom kinds, 0 overrides -- the count that changes here is the one made of duplicate nodes): * ILIKE. ``expression/ilike.py`` declared ``ILikePredicate`` under the same ``format_ilike_predicate`` entry core's node declares, so one concept had two classes and the artifact could not say which it meant. The module is gone; ``PostgresILIKEMixin.format_ilike_predicate`` is the whole PostgreSQL side, and the two test modules import core's node. * ALTER/VALIDATE CONSTRAINT. ``ddl/constraint.py`` exported one class under four names each -- zero call sites, no old name to be compatible with -- and the VALIDATE one added nothing at all. ``PostgresValidateConstraint`` is deleted (core's ``ValidateConstraintAction`` is what callers build); the ALTER one keeps its one real addition, ``constraint_kind`` as a readable property that makes ``get_params()`` resolve the parameter core stores under another name, and is renamed ``PostgresAlterConstraintAction`` so the class carries the suffix its formatter already had. * ENUM type fragments. ``CreateEnumTypeExpression`` / ``DropEnumTypeExpression`` / ``AlterEnumAddValueExpression`` were ``pass`` subclasses of the ``Postgres*`` classes -- same behaviour, a second kind, no backend prefix. Deleted; the ``Postgres*`` classes are the only spelling. ``EnumTypeNameExpression`` / ``EnumValuesExpression`` are real nodes but their kinds had no backend prefix and their formatter names did not match them; renamed ``PostgresEnumTypeNameExpression`` / ``PostgresEnumValuesExpression`` with ``format_postgres_enum_*`` entries. * PARTITION BY. ``PostgresPartitionClause`` was an empty subclass of core's ``PartitionClause``: no field, no formatter of its own, one more kind for one concept. Removed; PostgreSQL renders core's clause. * Compound-word kind. ``PostgreSQLRowCountWildcard`` derived ``postgre_sql_row_count_wildcard`` -- ``PostgreSQL`` splits into two words under the class-name rule, while every other class here says ``Postgres``. Renamed ``PostgresRowCountWildcard`` (kind ``postgres_row_count_wildcard``). Audited and left alone: every ``Postgres*`` node that subclasses the core node of its concept and adds a typed field (``PostgresAlterColumn.using``, ``PostgresExcludeBranch.elements``/``where``, the type definitions, the domain actions) -- those are derived nodes with a formatter of their own, not redeclarations. The dialect MRO was read end to end: no PostgreSQL mixin sits behind a core class that would shadow it.

The harness is now this repository's own (``expression_roundtrip_harness.py``), vendored when testsuite deleted the shared module; its comparison learns that a ``(str, Enum)`` member and the word it carries are the same recorded value, because JSON has no enum and a constructor may legitimately keep the word. Matrix changes: * ``values.*`` rows are gone -- there is no class per value kind. In their place ``test_value_kind_plane`` walks all fourteen kinds: wire name, JSON payload type (NaN/+-Inf as text, Decimal and timedelta as text, bytes as base64, list vs tuple preserved, everything else a plain scalar) and the round-trip through all three channels. The set is pinned in both directions against ``LiteralKind``, and a ``float_value`` payload that is not finite is asserted to be refused by the value layer rather than rendered. * The removed K1 classes leave no rows: ``PostgresPartitionClause``, ``PostgresValidateConstraint``, the three enum compat subclasses and the six constraint aliases. * Constructors added for classes the generic guess could not build for real reasons (a closed word set, a field name, an inline DDL condition, a value rather than text, a declared-result annotation wrapping a column), and for ``CustomType`` (its ``raw`` is keyword-only), so it leaves UNCONSTRUCTIBLE. * ``_CODEC_GAPS`` / ``_CODEC_RENDER_GAPS`` pin what core's codec cannot carry or cannot read back, per class and per channel with the exception type: the XML codec writes a ``(str, Enum)`` with ``Enum.__str__`` (the member's *name*), a dataclass parameter has no encoding at all (``XMLAttribute``, ``XMLForestItem``, ``XMLTableColumn``, ``ReferentialAction``, ``TriggerEvent``, ``ViewOptions``, ``GraphColumn``, ``GeneratedColumnType``), ``CreateTableCloneMode`` is a plain Enum, and the two XML nodes' formatters read ``.value`` off a decoded word. Nothing else may lose a parameter, and each entry is exact in both directions. Backend defects the matrix surfaced, fixed here: * ``PostgresCollationMixin`` read ``expr.collation_options``; core's node declares ``schema``, so every COLLATE raised ``AttributeError``. * ``format_alter_database_statement`` compared against ``AlterDatabaseAction.CONNECTION_LIMIT`` / ``.TABLESPACE``, which core does not declare -- every ALTER DATABASE died before rendering. It now recognises PostgreSQL's two extra actions by word, resolves a decoded word back to the core member, delegates the rest to core's formatter explicitly (``super()`` reached the protocol stub and answered ``None``), and refuses an unknown action. * ``mode is LoggingMode.LOGGED`` answered "not LOGGED" for a round-tripped word and rendered the opposite setting; it compares and spells the word now, and refuses an unknown one. * ``PostgresAlterTableRlsExpression`` read ``expr.mode.value``, which is gone after a decode. * ``hstore_literal``/``ltree_literal``/``xid8_literal`` chained ``.cast()`` onto a ``Literal``; casting is a ``SQLValue`` capability and ``Literal`` is the value node, so they build a ``CastExpression`` over it. * The four value wrappers declared ``family``, stored it as ``_family``, and no code ever read it -- removed (rules §4.4: a parameter that changes nothing). * Every PostgreSQL-owned enum is now ``(str, Enum)`` with ``__str__ = str.__str__`` (§11.3), so the word is what str() and the artifact carry. Test evidence: the full matrix plus the domain round-trip file -> exit 0 (``531 constructible, 2 pinned-unconstructible; 471 rendered, 37 unsupported, 20 non-render, 3 unmodelled``). ruff clean on every touched file. --- .../backend/impl/postgres/collation.py | 7 +- .../backend/impl/postgres/config.py | 7 +- .../impl/postgres/expression/advisory/lock.py | 9 +- .../backend/impl/postgres/expression/copy.py | 15 + .../impl/postgres/expression/ddl/column.py | 7 +- .../impl/postgres/expression/ddl/domain.py | 74 +- .../impl/postgres/expression/ddl/index.py | 7 +- .../impl/postgres/expression/ddl/policy.py | 22 +- .../postgres/expression/ddl/rls_config.py | 9 +- .../postgres/expression/ddl/table_settings.py | 7 +- .../impl/postgres/expression/values.py | 32 +- .../backend/impl/postgres/functions/citext.py | 2 +- .../impl/postgres/functions/data_type.py | 13 +- .../backend/impl/postgres/functions/enum.py | 15 +- .../backend/impl/postgres/functions/hstore.py | 2 +- .../backend/impl/postgres/functions/ltree.py | 4 +- .../impl/postgres/functions/pgvector.py | 111 +- .../backend/impl/postgres/mixins/collation.py | 20 +- .../impl/postgres/mixins/ddl/rls_config.py | 8 +- .../postgres/mixins/ddl/table_settings.py | 14 +- .../impl/postgres/mixins/ddl_database.py | 80 +- .../impl/postgres/storage_parameters.py | 12 +- .../dialect/test_object_kind_guards.py | 41 +- .../backend/expression_roundtrip_harness.py | 1216 +++++++++++++++++ .../test_domain_expression_roundtrip.py | 15 +- .../backend/test_expression_roundtrip_all.py | 635 +++++++-- 26 files changed, 2136 insertions(+), 248 deletions(-) create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/expression_roundtrip_harness.py diff --git a/src/rhosocial/activerecord/backend/impl/postgres/collation.py b/src/rhosocial/activerecord/backend/impl/postgres/collation.py index ec422542..638682ec 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/collation.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/collation.py @@ -7,8 +7,13 @@ from typing import Optional, Tuple -class PostgresCollation(Enum): +class PostgresCollation(str, Enum): """Common PostgreSQL collations for expression-level COLLATE.""" + #: A member *is* the word it carries, so ``str()`` -- what the artifact + #: and every f-string spell a closed value with -- names the value rather + #: than the member (rules §11.3: ``(str, Enum)`` alone is not enough -- + #: ``Enum.__str__`` wins unless it is replaced). + __str__ = str.__str__ C = "C" POSIX = "POSIX" diff --git a/src/rhosocial/activerecord/backend/impl/postgres/config.py b/src/rhosocial/activerecord/backend/impl/postgres/config.py index b1b18c7d..990f8cf7 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/config.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/config.py @@ -8,7 +8,7 @@ from rhosocial.activerecord.backend.config import ConnectionConfig, ConnectionPoolMixin -class RangeAdapterMode(Enum): +class RangeAdapterMode(str, Enum): """Range adapter mode selection.

Renamed ``NetworkValueExpression`` / ``RangeValueExpression`` / ``HstoreValueExpression`` / ``LtreeValueExpression`` -> ``Postgres*ValueExpression``, ``PartitionValue`` -> ``PostgresPartitionValue``, ``CreateMultirangeTypeExpression`` / ``MultirangeAggFunctionExpression`` -> ``Postgres*``, ``MaterializedViewAlterAction`` -> ``PostgresMaterializedViewAlterAction``, and the two private helpers ``_LegacySqlExpression`` / ``_UnsupportedDomainAction`` -> ``_PostgresLegacySqlExpression`` / ``_PostgresUnsupportedDomainAction``. Every affected ``format_method`` follows its kind, so class name, kind and entry are one identity. * ``PostgresAlterColumn`` -> ``PostgresAlterColumnAction``: the action carries the suffix its formatter (``format_alter_column_action``) and its base (``AlterColumnAction``) already had. * The four value wrappers declared ``family``, stored ``_family``, and nothing read it. Removed -- a parameter that changes nothing is not a parameter. Kind hygiene is now a test (``dialect/test_kind_hygiene.py``): no backend class may claim a kind core issues; a backend-owned kind must be ``postgres_*``; a declared node's formatter must be ``format_`` (with an explicit, two-way-checked table for the families that share one entry); and every enum in the package must be ``(str, Enum)`` whose ``str()`` is its value. Test discipline (expression-dialect §12, §12.1): * The live-connection half of the literal work moved out of ``test_literal_values.py`` into ``test_literal_values_integration.py``, on the scenario-parameterised ``postgres_backend`` fixture. What stays is construct-and-render only, with the measured facts (and where to re-measure them) recorded in the docstring. ``conftest.py`` in the expression directory makes ``-n auto --dist=loadgroup`` the default there. Serialization obligations (guide §13): * §13.1: ``format_binary_operator`` spells the operator through ``.symbol`` when it is a ``ComparisonOperator`` -- ``expr.op`` is now the word (``EQ``), and the character is what SQL wants. A plain string operator (pg_trgm, range) is used as it is. * §13.4: audit of every ``*_need_quote`` pass-through in this backend; all are real bools, no change needed. Test evidence: the kind-hygiene file, the literal files (expression and integration), the matrix, ``test_expression_roundtrip_all``, ``test_postgres_dialect_security``, ``test_extension_type_operations``, ``test_ddl_expressions``, ``test_ddl_alter_config``, ``test_materialized_view``, ``test_alter_table_if_exists`` -> exit 0. ruff clean. --- .../postgres_specific_features/partition.md | 2 +- .../impl/postgres/expression/__init__.py | 8 +- .../impl/postgres/expression/ddl/__init__.py | 20 +- .../postgres/expression/ddl/alter_column.py | 6 +- .../impl/postgres/expression/ddl/domain.py | 18 +- .../postgres/expression/ddl/multirange.py | 12 +- .../impl/postgres/expression/ddl/mv.py | 24 +- .../impl/postgres/expression/ddl/partition.py | 14 +- .../impl/postgres/expression/values.py | 104 ++++---- .../impl/postgres/functions/vector_search.py | 9 +- .../impl/postgres/mixins/ddl/column.py | 6 +- .../impl/postgres/mixins/ddl/domain.py | 14 +- .../impl/postgres/mixins/ddl/partition.py | 20 +- .../impl/postgres/mixins/expression.py | 12 + .../impl/postgres/mixins/materialized_view.py | 6 +- .../impl/postgres/mixins/types/multirange.py | 12 +- .../impl/postgres/protocols/ddl/partition.py | 6 +- .../postgres/protocols/materialized_view.py | 4 +- .../postgres/protocols/types/multirange.py | 4 +- .../dialect/test_alter_table_if_exists.py | 12 +- .../backend/dialect/test_kind_hygiene.py | 252 ++++++++++++++++++ .../backend/dialect/test_materialized_view.py | 10 +- .../backend/postgres/test_ddl_expressions.py | 24 +- .../test_extension_type_operations.py | 4 +- .../backend/postgres/test_literal_values.py | 99 +------ .../test_literal_values_integration.py | 126 +++++++++ .../backend/test_expression_roundtrip_all.py | 28 +- .../backend/test_postgres_dialect_security.py | 16 +- 28 files changed, 587 insertions(+), 285 deletions(-) create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/dialect/test_kind_hygiene.py create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/postgres/test_literal_values_integration.py diff --git a/docs/zh_CN/postgres_specific_features/partition.md b/docs/zh_CN/postgres_specific_features/partition.md index 4fb0bbf4..312685e7 100644 --- a/docs/zh_CN/postgres_specific_features/partition.md +++ b/docs/zh_CN/postgres_specific_features/partition.md @@ -14,7 +14,7 @@ PostgreSQL 自 10 版本起支持声明式分区，11+ 版本功能显著增强 ```python from rhosocial.activerecord.backend.impl.postgres.expression.ddl.partition import ( -

Two things there still opened one, and one configuration still left parallelism to whoever remembered the flag. * ``test_literal_values.py`` keeps the wiring, the data-position bindings and the inline spellings, and nothing else. Its ``TestLiveLiteralRoundTrip`` -- the sentinel, the CREATE TABLE with the rendered DEFAULTs, the read-back through ``INSERT ... DEFAULT VALUES`` -- moved to ``test_literal_values_integration.py`` beside it, where the scenario-parameterised ``postgres_backend`` fixture already lives. The measured interval facts stay in the docstring that recorded them, with a pointer to where a re-measurement goes; the numbers did not change and are not restated in two places. * ``tests/.../backend/expression/conftest.py`` makes ``-n auto`` and ``--dist=loadgroup`` this directory's default, and ``pyproject.toml`` pins ``--dist=loadgroup`` for the suite: a case runs on its own only when it carries an explicit ``xdist_group``, and the reason for that marker is written where it is used. ``-n 0`` / ``-p no:xdist`` still opt out. * ``xdist_group`` is declared as a marker rather than left to the plugin, so a typo in its name fails instead of being ignored. Also in this commit, for the same rule set: the backend's transaction mixin and tests follow core's ``with_*`` setters (``expr.isolation_level()`` -> ``expr.with_isolation_level()`` and the three siblings), and the parse-contract sweep reads ``parse_roundtrip_failures`` from this repository's vendored harness now that the shared testsuite module is gone. Test evidence: the expression directory (parallel default in effect), ``test_literal_values.py``, ``test_literal_values_integration.py`` (live; skipped where no scenario server is configured), ``test_expressions_transaction.py``, ``test_transaction_advanced_features.py``, ``test_postgres_type_protocol.py``, ``test_ddl_alter_config.py``, ``test_object_kind_guards.py`` -> exit 0.

Each formatter now collects the conditions its node's parameters ask for and joins them into the WHERE tail in one place, which is how the MySQL backend already spells the same family (its ``format_table_list_query`` and friends collect conditions and join them once). Migrated formatters, each driven only by the parameters the core introspection node already collects: - format_table_list_query: include_system and table_type collect conditions - format_column_info_query: include_hidden collects a condition - format_view_list_query: include_system collects a condition - format_materialized_view_list_query: include_system collects a condition - format_trigger_list_query / format_trigger_info_query: the optional table_name collects a condition and its bind parameter Local evidence: the rendered SQL was compared byte-for-byte over 22 shapes (every include_views / include_system / table_type / include_hidden / table_name branch of the whole introspection family, plus the materialized view queries); all 22 are identical, parameters included. The one oddity kept on purpose is format_column_info_query repeating ``NOT a.attisdropped`` when include_hidden is false: the base query already excludes dropped columns, the repeat is what this query has always rendered, and it is now a named fragment with a comment saying so rather than an anonymous append. ruff clean on the touched file; the dialect-level materialized-view introspection tests and the whole DB-free introspection suite are green; the live-DB legs stay for CI. --- .../impl/postgres/mixins/introspection.py | 159 ++++++++++-------- 1 file changed, 88 insertions(+), 71 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/mixins/introspection.py b/src/rhosocial/activerecord/backend/impl/postgres/mixins/introspection.py index 7e19abf8..209cfb1a 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/mixins/introspection.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/mixins/introspection.py @@ -185,6 +185,28 @@ def format_table_list_query(self, expr: "TableListExpression") -> Tuple[str, tup else: relkind_filter = "('r', 'f', 'p')" + # Each collected parameter contributes its own condition, and the + # conditions are joined into the WHERE tail in one place: the query is + # assembled once from named fragments rather than grown one append at + # a time, so its whole shape stays visible together. + conditions = [] + + if not include_system: + conditions.append("c.relname NOT LIKE 'pg_%%'") + + if table_type == "BASE TABLE": + conditions.append("c.relkind IN ('r', 'p')") + elif table_type == "VIEW": + conditions.append("c.relkind = 'v'") + elif table_type == "MATERIALIZED VIEW": + conditions.append("c.relkind = 'm'") + + # The first condition continues the line the base WHERE clause leaves + # open, the ones after it follow on that same line, and ORDER BY + # closes the clause. + filters = "\n AND " + " AND ".join(conditions) if conditions else "" + closing = " ORDER BY c.relname" if conditions else "\n ORDER BY c.relname" + sql = f""" SELECT c.relname as table_name, CASE c.relkind @@ -200,25 +222,9 @@ def format_table_list_query(self, expr: "TableListExpression") -> Tuple[str, tup FROM pg_class c JOIN pg_namespace n ON c.relnamespace = n.oid WHERE n.nspname = {self.p()} -

Core issues no node for this query, so this backend declares two: - PostgresDatabaseSizeFunction (kind postgres_database_size_function) owns the ``pg_database_size(name)`` call and carries the database name as a bind parameter. The generic FunctionCall is not used for it: core reserves that node for user-defined functions, and a standard function the server ships is a named class an artifact can resolve. - PostgresDatabaseSizeQueryExpression (kind postgres_database_size_query_expression) owns the row shape -- the SELECT and the size_bytes alias callers read -- and renders the call through the function node, so the spelling lives in one place and the row shape in another. get_storage_info now builds the node with the database name and executes what it renders; the SQL text and its parameter are exactly what the f-string produced ("SELECT pg_database_size(%s) as size_bytes", (db_name,)), compared byte-for-byte.

A SQL string is a formatting artefact: the node collects the parameters, the dialect formatter writes the text, and the executing layer only constructs and runs. New nodes (kind from the class name, formatter in PostgresIntrospectionCapabilityMixin): PostgresSettingsQuery, PostgresActivityCountQuery, PostgresShowStatement, PostgresDatabaseListQuery, PostgresSchemaStatsQuery, PostgresCurrentDatabaseQuery, PostgresRoleListQuery, plus PostgresEnumTypeExistsQuery/PostgresEnumTypeValuesQuery and PostgresSetConstraintsStatement. The settings query's name list and the enum lookups travel as bind values now; the SET CONSTRAINTS name goes through the dialect's identifier quoting, so a name carrying a quote can no longer break the statement or escape it; PostgresShowStatement validates its parameter at construction. formatter-type imports land under TYPE_CHECKING, and format_postgres_set_constraints_statement is declared in PostgresTransactionSupport so the reverse-coverage conformance test passes. Rendered SQL is otherwise unchanged; the live-DB legs are covered by CI.

FROM pg_class c JOIN ...`), and the status introspector held fourteen more (org guide §18: "postgres 的内省是手拼重灾区"). Every one of them is now an expression tree: a projection of `Column` / `FunctionCall` / `CaseExpression` nodes, a relation or a chain of `JoinClause`s, a conjunction of predicates, and an optional ordering and grouping. No formatter in this wave writes a clause, keyword or separator. Migrated (each driven only by the parameters the core node already collects): - `format_database_info_query`, `format_table_list_query`, `format_table_info_query`, `format_column_info_query`, `format_index_info_query`, `format_foreign_key_query`, `format_view_list_query`, `format_view_info_query`, `format_materialized_view_list_query`, `format_materialized_view_info_query`, `format_trigger_list_query`, `format_trigger_info_query` - `format_postgres_database_size_function` / `_query`: the call is a `FunctionCall`, the row shape a `QueryStatement` (the earlier form built the call as a string and concatenated `SELECT ... as size_bytes`) - `format_postgres_settings_query`, `format_postgres_activity_count_query`, `format_postgres_database_list_query`, `format_postgres_schema_stats_query`, `format_postgres_current_database_query`, `format_postgres_role_list_query`, `format_postgres_enum_type_exists_query`, `format_postgres_enum_type_values_query` - `format_postgres_show_statement`, moved to `mixins/show.py`: `SHOW` names one run-time parameter, it is not a catalog query, and MySQL and MariaDB already keep the two apart (`show/dialect.py` versus the introspection mixin). Subqueries are nodes, not text: `is_primary_key` and `has_unique_index` are `ExistsPredicate` over a nested `QueryStatement`; `a.attnum = ANY(i.indkey)` is an `AnyPredicate`; `con.confkey[array_position(...)]` is an `ArrayOperation` subscript; the trigger `timing` bitmask is a `CaseExpression` over `BinaryExpression`. Parameter tuples are unchanged: every caller-supplied schema, table, view, trigger or database name still travels as `%s` in the same order, and every catalog constant (relkind codes, table-type labels, the `pg_` prefix filter) is still literal-inline and binds nothing. Baseline: `(sql, params)` for 50 shapes (every include_views / include_system / table_type / include_hidden / table_name / schema branch of the family, plus the status and enum nodes) captured before and after into `postgres-intro-baseline.json` / `postgres-intro-after.json`. Result: zero parameter-sequence differences, zero projection-order or alias-name differences, and 49/50 cases identical after normalizing only whitespace, case, the `AS` keyword on a reference and explicit grouping. The one remaining diff is `format_postgres_schema_stats_query` (`n.nspname NOT IN (...)` renders as `NOT (n.nspname IN (...))`): the same predicate with the same operands, and the negated form is what the logical node writes. Two behaviour changes, both deliberate: - a blank enum type name is refused at render time rather than producing `WHERE t.typname = %s` with an empty bind (`PostgresEnumTypeExistsQuery` / `PostgresEnumTypeValuesQuery`), because no catalog row can match it; - `format_trigger_list_query` now always orders by `t.tgname`. The old text ordered in both branches and differed only in its leading whitespace, so no caller sees a different row set -- only the accidental asymmetry is gone.

Every row of the codec pin table that existed because of those two defects is now stale: the classes report `lost []` against a pin that still names a channel. Dropped from `_CODEC_GAPS` (14 of its 21 rows): * 9 datetime nodes -- DatePart, DateTimeAdd, DateTimeDiff, DateTimeSubtract, DateTrunc, Extract, ExtractField, Interval and _ExtractBase. Each pinned `xml` as ValueError; the XML codec now writes the word instead of `DateTimeField.YEAR`. * XMLParseExpression / XMLSerializeExpression -- each pinned `xml` as an unroundtrippable `document_type`. The word travels now. * ForeignKeyConstraint (ReferentialAction), CreateTriggerStatement (TriggerEvent), ColumnGeneratedConstraint (GeneratedColumnType) -- pinned all three channels as TypeError because a bare Enum is not a JSON scalar. Parameters round-trip everywhere now. * _XML_ENUM_NAMES, a frozenset nothing read, is gone with the gap it described. Residual, kept on purpose (7 rows): XMLAttribute, XMLForestItem, XMLTableColumn, ViewOptions and GraphColumn are *dataclass* parameters, which no encoder accepts -- a separate defect core has not touched. CreateTableCloneStatement keeps its two rows because its constructor still refuses the CreateTableCloneMode word the codec now hands it. No residual enum loss of any kind. `_CODEC_RENDER_GAPS` lost its two `dict` pairs (that channel hands the constructor the member and renders) and gained CreateTriggerStatement `json`/`xml`: its parameters survive, but the formatter reads `.value` unconditionally, so the plain word it gets back does not render -- the same render-side defect as the XML document-type pair, not a loss.

The reason is not a parser quirk -- the definition is stored and run again later, where a bound value has no meaning -- so the statement is refused by name, with the way out named, rather than rendered for the server to reject. The way out is what the caller has to know: build the query with an inlined literal. PostgreSQL's own test helper already does exactly that ("An inlined literal: MV/CTAS bodies reject bind parameters on PostgreSQL"), which is why the gap survived here -- the helper was right and the formatter did not enforce it. CREATE TABLE ... AS is deliberately left alone. Its body is executed once, so a bound value is meaningful, and the server accepts it: measured on 19beta4, "CREATE TABLE t AS SELECT $1 FROM s" is accepted and the table is created, while the same query as a materialized view is refused.

This change makes PostgreSQL's code match that, and settles what a type position holds while it is there. **A formatter owns its production.** Core's dialect mixins held six private renderers serving families of thin ``format_*(self, expr)`` wrappers. The wrappers were formatters; the bodies were not, and being private they could not be overridden. The bodies moved into the formatters that used them. PostgreSQL's ``TRUNC`` -- which core spelled through one of them -- now owns its production, as every other formatter does. **A type-name position holds a type.** The positions that carried a raw string guarded it with a character class in the base class, which neither matched what the engines accept nor kept the value inside its syntactic position. A position now holds a type node; a name the framework does not model becomes the framework's name node, whose name the grammar validates. A routine's type names are claimed the same way. **Binding is the caller's call.** A DDL position that cannot bind says so through PostgreSQL's own capability switch, and a value the caller chose to inline is inlined. The framework does not refuse on the caller's behalf. **The backend's own answers are the effective ones.** PostgreSQL's mixin precedes the core mixin it overrides, so the override is not dead code, and a test holds that in place. **The mixin list says what it is for.** The base-list convention is written down where the list is, and the function examples reach their constructors through ``functions as F``, so a reader sees at a glance which names the framework provides. --- .../backend/impl/postgres/dialect.py | 22 ++++----- .../postgres/examples/ddl/create_table.py | 4 +- .../impl/postgres/examples/query/aggregate.py | 8 ++-- .../impl/postgres/examples/query/constants.py | 35 +++++--------- .../impl/postgres/examples/query/subquery.py | 4 +- .../impl/postgres/expression/ddl/domain.py | 2 +- .../impl/postgres/expression/ddl/type.py | 2 +- .../impl/postgres/mixins/ddl/routine.py | 10 +++- .../backend/impl/postgres/mixins/ddl_table.py | 10 ++++ .../backend/impl/postgres/mixins/ddl_view.py | 11 +++++ .../impl/postgres/mixins/expression.py | 11 ++++- .../backend/impl/postgres/mixins/features.py | 20 ++++++++ .../impl/postgres/mixins/materialized_view.py | 28 +++++------ .../postgres/protocols/materialized_view.py | 10 ++++ .../backend/impl/postgres/protocols/table.py | 10 ++++ .../backend/impl/postgres/protocols/view.py | 10 ++++ .../backend/postgres/test_ddl_objects.py | 18 +++++-- .../backend/test_postgres_dialect_security.py | 40 +++++++++++++--- .../test_postgres_protocol_conformance.py | 48 +++++++++++++++++++ 19 files changed, 227 insertions(+), 76 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py index 4e312ca8..7d8ec840 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/dialect.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/dialect.py @@ -367,6 +367,14 @@ class PostgresDialect( + # The bases below come in bundles: a backend mixin, then the core bundle + # it stands in for.

The class renames are mechanical and follow two rules. A node that renders a whole statement is a ``*Statement``, so the nodes that rendered a statement behind the name ``*Expression`` lost the false suffix; and the introspection nodes render a SELECT, so they joined the ``*QueryStatement`` family the core set in place. Formatters gained, dropped or respelled no word any more: the qualifier a capability needs lives in the class name (``PostgresCreateFunctionDdlStatement``) rather than in a spelling no other word of the kind carries. Three collisions were deliberately avoided rather than fixed by renaming, and each is recorded in the matrix: * ``format_create_function_statement`` and ``format_drop_function_statement`` are core capabilities for core's generic routine nodes. PostgreSQL has its own node and formatter for CREATE/DROP FUNCTION -- it carries the schema, the argument list and the body -- so those names stay core's and the ``_ddl_`` spellings keep serving the PostgreSQL node. * ``format_refresh_materialized_view_statement`` routes core's generic node to this backend, so the ``_pg_`` spelling keeps serving the PostgreSQL-specific one. * ``format_pivot`` / ``format_unpivot`` stay shared with core. The addressed introspection nodes became ``*QueryStatement`` and their formatters ``*_query_statement``; the advisory-lock and pg_partman nodes are fragments and their formatters regained the ``_expression`` suffix; the network, range, hstore and ltree values are values, not expressions, and dropped the suffix the way ``Literal`` did. --- docs/en_US/ddl/README.md | 14 +-

Its tests moved with it, and each now asserts the reason as well as the verdict -- "refused" and "refused because the extension was never probed" are different claims, and only the second tells the caller what to do about it. One behaviour is deliberately not carried over. The fork answered ``True`` for a function nobody registered, which read a typo as "supported". ``supports_functions()`` has no entry for such a name, so the caller can tell "unknown" from "supported"; the test now pins that absence instead of the old default. --- .../backend/impl/postgres/mixins/function.py | 68 ----------- .../postgres/test_function_versions.py | 115 ++++++++++-------- .../backend/test_dialect_function_support.py | 44 ++++--- 3 files changed, 95 insertions(+), 132 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/mixins/function.py b/src/rhosocial/activerecord/backend/impl/postgres/mixins/function.py index a565b481..c280cccd 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/mixins/function.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/mixins/function.py @@ -6,7 +6,6 @@ if TYPE_CHECKING: from rhosocial.activerecord.backend.impl.postgres.function_versions import ( FunctionSupportInfo, - FunctionVersionRequirement, ) @@ -102,70 +101,3 @@ def _check_function_support(self, func_name: str) -> "FunctionSupportInfo": return FunctionSupportInfo(supported=False, reason="extension_version_insufficient") return FunctionSupportInfo(supported=True) - - def _is_postgres_function_supported(self, func_name: str) -> bool: - """Check if a PostgreSQL function is supported based on version and extensions. - - Checks: - 1.

Call the cache object instead, keeping the key arguments and their schema/extra namespacing unchanged.

Sequences are read from ``information_schema.sequences``, the SQL standard view every supported server carries, with ``pg_sequences`` joined beside it for the two columns the standard view omits (``cache_size`` and ``last_value``). That catalog view arrived in PostgreSQL 10, so the join is gated on the server version: a 9.x server is asked the narrower question and reports those two columns as absent, rather than failing on a relation it does not have. Each row is a frozen ``SequenceInfo``: ``cycle_option`` is normalised from the server's YES/NO text to a bool, and a sequence that never handed out a value reports ``last_value`` as None instead of an error. The question is still assembled from expression objects in ``expression/introspection.py`` and rendered by ``format_sequence_*_query_statement`` on the dialect mixin -- no query text is ever concatenated. Installed extensions become a first-class question of the schema introspector, where the objects that live in a schema are read: ``list_extensions`` / ``get_extension_info`` / ``extension_exists`` answer from ``pg_extension`` joined to ``pg_namespace`` and cache under a schema-scoped key. ``status.get_overview()`` keeps its own call for the overview it builds. The CLI answers for both families -- ``materialized-views`` and ``sequences``, each listing the schema or one named object -- through ``backend.introspector`` and the existing output provider. Both adapt the dialect first, because the sequence query reads the server version and an unadapted dialect has none to read. Tests read a live server: the sequence/MV fixture creates a sequence with non-default attributes and a populated materialized view, and the CLI cases drive ``main()`` for the two new subcommands, asserting non-empty output for a listing and a single object. A new example (``examples/introspection_objects.py``) prints both families and then measures the cache -- questions asked and wall time, cold versus warm -- by wrapping the introspector's executor; with no server it names the environment variables to set and exits non-zero without inventing a reading. --- .../backend/impl/postgres/cli/introspect.py | 99 ++++- .../impl/postgres/examples/conftest.py | 9 + .../examples/introspection_objects.py | 251 ++++++++++++ .../impl/postgres/expression/introspection.py | 72 ++++ .../postgres/introspection/introspector.py | 361 ++++++++++++++++++ .../impl/postgres/introspection/types.py | 46 +++ .../impl/postgres/mixins/introspection.py | 169 +++++++- .../feature/backend/introspection/conftest.py | 59 +++ .../test_introspection_cli_objects.py | 207 ++++++++++ .../test_introspection_sequences.py | 259 +++++++++++++ 10 files changed, 1525 insertions(+), 7 deletions(-) create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/examples/introspection_objects.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/introspection/types.py create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_cli_objects.py create mode 100644 tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_sequences.py diff --git a/src/rhosocial/activerecord/backend/impl/postgres/cli/introspect.py b/src/rhosocial/activerecord/backend/impl/postgres/cli/introspect.py index a20b5632..8e33d163 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/cli/introspect.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/cli/introspect.py @@ -2,7 +2,8 @@ """introspect subcommand - Database introspection.

The cause was not the objects themselves: a previous run that died before its teardown left arx_cli_demo_tbl and arx_cli_demo_mv behind, the fixture's setup then hit the duplicate part-way through, and every later assertion in the module read a half-built schema. Two changes. The drops run first and tolerate a leftover -- refusing to continue is what turned one dead run into twelve failing jobs -- and the table drop carries CASCADE so a straggler view cannot outlive its table. The creates keep the privilege of failing loudly: if a CREATE fails, the objects the tests assert on are genuinely absent and that must be an error rather than a test that reads nothing. The clause order in the drops is now the dependency order too, because a view names its table and the table cannot go first.

Forgiving drops cannot fix that, because the collision is on the CREATE -- the matrix runs a dozen jobs against the same scenario servers, and two of them reaching `CREATE TABLE arx_cli_demo_tbl` at once is a duplicate regardless of how politely the preceding DROP behaved. Each run now suffixes its three names with a per-process value, so a leftover from a dead run and a concurrent job are both simply other rows. The fixture yields the names and every assertion reads them from there instead of from a module constant, which is what was wrong with the first attempt: the tests kept the fixed names and the new ones were never looked at. The drops stay forgiving and ordered by dependency (the view before the table, CASCADE on the table), and the creates still fail loudly -- a failed CREATE means the objects the tests assert on are absent, which must not pass quietly.

The assertions now read the same `_server_has_pg_sequences()` gate the introspector resolves through, so a 9.x server is checked for the documented absence rather than for a value it cannot produce.

CASCADE` still landed on a relation another was mid-read on: the server reported "could not open relation with OID" during the fixture's own setup, which is what the last postgres job showed. Each run now creates a schema carrying its suffix, puts the three objects in it, and asks the CLI for that schema (`--schema` is already honoured by every subcommand). Nobody else drops a relation inside another worker's namespace, so the "open relation" failure has no route to reproduce. The cyclic fixture dependency is gone as well: `conn_args` used to be read by `cli_objects`, which then had to be re-declared to point back at it. Both now read one `_server_config()` helper, and the schema assertion reads the value the fixture created rather than assuming `public`.

The ``--schema`` flag is removed as well, per the connection-layer rule: a run already names one database, so the scope is fixed before the parser is built and asking a second time can only disagree with the connection. Every call site passes ``schema=None`` and lets the introspector resolve ``config.default_schema``, then ``search_path``'s first entry, then ``public``. The epilog and the README lose their schema example and their "the schema is explicit" note; the README says instead that the connection fixes the scope. ``--schema`` is now refused like any unknown option. The CLI-object tests follow: their fixture puts the objects in the default schema again (that is the only scope a run can reach), the connection args no longer pass a schema, and two parser-contract tests pin what the parser offers -- the flag is refused, and ``--help`` lists every type without it. --- .../backend/impl/postgres/cli/README.md | 13 ++- .../backend/impl/postgres/cli/introspect.py | 58 ++++------ .../test_introspection_cli_objects.py | 107 ++++++++++++------ 3 files changed, 102 insertions(+), 76 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/cli/README.md b/src/rhosocial/activerecord/backend/impl/postgres/cli/README.md index 0b934894..9467a0c2 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/cli/README.md +++ b/src/rhosocial/activerecord/backend/impl/postgres/cli/README.md @@ -35,7 +35,6 @@ instead of the family. | Option | Default | Description | | :--- | :--- | :--- | | `-o, --output` | `table` | `table` (rich), `json`, `csv`, `tsv`. | -| `--schema` | `public` | The schema to read.

No aliases: the old names are gone.

From 7be369cb9462242502e2ef9541cfa0f4cd1fe9e4 Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Sun, 25 Oct 2026 17:21:48 +0800 Subject: [PATCH 65/77] test(postgres): test on 19rc1 and re-read a listing that lost a relation Two things kept the 19-era jobs from being a clean signal. The 19 job asked for ``postgres:19beta4``, an image superseded by the release candidate. The job name and the README's "CI-tested server versions" line now say ``19rc1`` so the matrix and the documentation cannot drift apart. Measurements recorded against 19beta4 in code and docs are left alone: they describe what was observed on that build, not what CI runs now. The other was a real failure, in three of the last run's four jobs, each naming a different OID: a listing answers for every object of its type in the schema the connection resolves, and describes each one by OID -- a materialized view's definition, a sequence's last value. PostgreSQL resolves that OID through the relcache, which is not part of the query's snapshot. The suite runs eight workers against one server, so a sibling worker's DROP can land between the snapshot that listed a row and the lookup that describes it, and the server answers "could not open relation with OID" instead of leaving the row out. A retry in a fresh process reads a fresh snapshot, in which the dropped relation is absent from the catalogue altogether. Only that error is retried, at most twice more, and the last attempt's result is returned unchanged: a persistent failure still fails the test with the server's own message. --- .github/workflows/test.yml | 4 +- README.md | 2 +- .../test_introspection_cli_objects.py | 47 +++++++++++++++---- 3 files changed, 41 insertions(+), 12 deletions(-) diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index 775882c2..09834e91 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -459,12 +459,12 @@ jobs: fail_ci_if_error: false test-postgres-19: - name: Python 3.14 / postgres 19beta4 + name: Python 3.14 / postgres 19rc1 runs-on: ubuntu-latest services: postgres: - image: postgres:19beta4 + image: postgres:19rc1 env: POSTGRES_DB: test_db POSTGRES_USER: root diff --git a/README.md b/README.md index 9008ac86..0fba9c78 100644 --- a/README.md +++ b/README.md @@ -24,7 +24,7 @@ _979088a_ - **Python**: `>=3.8` - **Core**: `rhosocial-activerecord>=1.0.0.dev0,<2.0.0` - **Driver**: `psycopg[binary]>=3.2.13` -- **CI-tested server versions**: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19beta4 +- **CI-tested server versions**: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19rc1 - **Published**: PyPI `1.0.0.dev16` ## Installation diff --git a/tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_cli_objects.py b/tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_cli_objects.py index 4d38d5c1..ffc88d18 100644 --- a/tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_cli_objects.py +++ b/tests/rhosocial/activerecord_postgres_test/feature/backend/introspection/test_introspection_cli_objects.py @@ -11,6 +11,7 @@ import json import socket import sys +import time import uuid from contextlib import redirect_stderr, redirect_stdout @@ -150,15 +151,43 @@ def _reachable(config) -> bool: return True -def run_cli(argv): - out, err = io.StringIO(), io.StringIO() - exc = None - with redirect_stdout(out), redirect_stderr(err): - try: - main(argv) - except SystemExit as e: - exc = e - return out.getvalue(), err.getvalue(), exc +#: The error PostgreSQL answers when a catalogue row names a relation that is +#: gone by the time the row's definition is read. +_CATALOG_CHURN = "could not open relation with OID" + + +def run_cli(argv, attempts=3): + """Run the CLI in-process, retrying a read that lost a relation mid-flight. + + A listing answers for every object of its type in the schema the connection + resolves, and it reads each one's definition (a materialized view) or last + value (a sequence) by OID.

6fec34b277002dfae2cdbf75600de3469227c40a Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Fri, 30 Oct 2026 19:06:04 +0800 Subject: [PATCH 73/77] feat(cli): the introspect types come with their capability switches - _TYPE_CAPABILITIES maps each type to the dialect switch that answers for it, and INTROSPECT_TYPES is derived from that mapping, so a type cannot be advertised without saying what decides whether it can be asked - the handler adapts the dialect once, at the entrance, and reads the switch before any branch runs; the per-branch introspect_and_adapt() calls in materialized-views and sequences are gone, because "can this be asked" was being decided by whichever branch happened to need the server version - a switch that answers False exits 2 with the shared message, instead of running the query and printing an empty list: "this server cannot report sequences" and "this database has no sequences" are different answers - partition metadata keeps its switch and gets no type: the introspector has no question for it, so there is no family to list The gates pin the vocabulary in both directions (the advertised list is the mapping; every switch the dialect answers is reachable, partition metadata excepted), run every type through both the synchronous and the asynchronous chain against a fake backend, and check that the switch is read only after adapting. ---

column saying which take one: required for columns/indexes/foreign-keys, optional for triggers and for the four single-object families, refused for tables and database - both guides state the exit codes the parser now uses: 1 when the run could not finish, 2 when the request cannot be served here, and that an empty listing is a successful answer rather than an error - the README examples ask

The testsuite stays on `fix/column-constraint-gates` on purpose: its own branch carries the two `pytest_compat` shims that keep pytest 9.2 working (the benchmark fixture's `_nodeid` read and xdist's loadgroup suffix), and those are not on the testsuite's release branch yet.
