Replaces the string/array database API with utopia-php/query value objects so adapters, schema, permissions, and queries share one typed surface.

Why this approach

Database::VAR_* / INDEX_* / PERMISSION_* and raw attribute arrays could not express the query-lib column, index, and relationship model. Adapters now take Attribute, Index, and Relationship objects; factories (Attribute::string(), Index::key(), Relationship::oneToOne(), …) are the call site. Generic constructors stay for dynamic types.

Follow-ups on this branch after the initial migration:

  • Typed factories for attributes, indexes, and relationships
  • Caret ranges for Utopia Composer constraints (^0.4, ^4.0) instead of asterisk (0.4.*)
  • updateDocument stamps $updatedAt with DateTime::nowAfter($old) so same-millisecond Redis updates stay unique
  • updateDocuments still uses DateTime::now() so bulk patches with unparseable $updatedAt do not throw
  • PHPStan baseline entries that no longer match the Index constructor were removed
  • A join no longer disables aggregate and group-by schema validation wholesale: an alias-qualified attribute has to name an alias the query set declared, matching the select/filter/order validators (Validator\Query\JoinedAttributes)
  • The empty-document cache marker is no longer written when the collection's cache epoch rotated under the read that justified it — saveWithLease leases the document key's own generation, which a rotation never touches, so a schema mutation landing mid-read could negative-cache a collection that by then existed
  • stddev() and variance() are pinned to the population statistic on every adapter (see below)
  • Collection metadata is invalidated under the tenant that reads it, so a cached _metadata entry can no longer outlive its own invalidation under tenant-per-document (see below)
  • Hard cut: Database::createCollection(Collection $collection) only. No string-id overload. Adapter createCollection(string $name, array $attributes = [], array $indexes = []) is unchanged.

_metadata invalidation under tenant-per-document

Under shared tables with tenant per document, every collection-metadata cache invalidation was aimed at a key no reader ever used, so anything cached for a collection definition survived its own invalidation for the full 24h TTL.

createDocument() purges through withDocumentTenant(), which switches to the document's own tenant. A collection definition is the one row createDocument() accepts without a tenant under tenant-per-document — the check at Traits/Documents.php explicitly exempts self::METADATA — so that switch set the tenant to null and getCacheBaseKeys() built the collection key with an empty tenant segment:

rotated by the writer:  …:<ns>::collection:_metadata#epoch
read by every reader:   …:<ns>:7:collection:_metadata#epoch

Two different keys. The epoch the writer rotated and the epoch the readers held were never the same one.

The visible consequences were a stale collection definition after a schema change, and — the one that bit — a negative $empty marker. A getCollection() that legitimately missed once while a project was still provisioning stayed a miss for every later request in that tenant, which surfaces as Collection not found out of anything that reads the collection. createCollection() performs such a read itself as its pre-existence check, so the collection could be unreadable to its own creator immediately after being created; with the fix reverted, createAttribute() straight after createCollection() throws NotFound.

The fix is to keep the adapter's tenant when the document carries none. A document that does carry a tenant still purges under it, which is what the switch exists for (GeneralTests::testSharedTablesTenantPerDocument covers that across the adapter matrix).

This is adapter-independent — it is cache-key arithmetic, not SQL — which is why it reproduced identically on MariaDB, MongoDB and PostgreSQL.

Statistical aggregate contract: population

Bare SQL STDDEV and VARIANCE are not portable. MySQL and MariaDB read both as the population statistic; PostgreSQL reads both as the sample statistic. Over the same four rows that is 67.0238 against 77.3985 — the same query, two different answers depending on the engine underneath. The query library emits the bare function verbatim (Method::Stddev => 'STDDEV'), so the ambiguity has to be resolved in the adapter.

The contract is population. SQL::applyFindFilters() rewrites Method::Stddev to Method::StddevPop and Method::Variance to Method::VarPop before the queries reach the builder, so every adapter emits STDDEV_POP / VAR_POP explicitly. Population was chosen because it is what MySQL and MariaDB already returned, what the query library's own ClickHouse builder already emits, and what leaves the existing stddevPop / varPop expectations unchanged.

stddevSamp() and varSamp() were never ambiguous and are untouched — that is how a caller asks for the sample statistic.

Consumers that branch on the adapter to pick an expected value (for instance an isPostgreSQL() check in a test) can drop the branch and assert the population value on every adapter.

Split out of this PR

The typed surface is the change worth reviewing on its own. Three framework layers that were built on top of it were split into separate stacked PRs; all three have since been closed and are not part of the landing plan:

Nothing in this repository or downstream calls them, so this PR stands alone.

Chain

Landing order, bottom up:

  1. utopia-php/database#823 — the query-lib migration itself
  2. utopia-php/abuse#124, utopia-php/migration#222, utopia-php/monorepo#206 — the schema call sites in the libraries (audit moved to the monorepo, so feat: adapt audit schema to query-lib Attribute and Index VOs audit#133 is closed in favour of monorepo#206)
  3. appwrite/appwrite#11649
  4. appwrite-labs/cloud#5410

Every consumer above pins dev-feat-query-lib through a VCS repository, so this PR has to be tagged before any of them can merge — the monorepo in particular refuses dev-branch pins.

utopia-php/database#968 (nested relationship queries) is not stacked on this branch but overlaps it in Database.php and the Memory/Mongo/Redis/SQL adapters. Agreed order is #823 first, then #968 rebased on top.

Verified

  • All 22 checks green, across the adapter matrix: MariaDB, MySQL, Postgres, SQLite, MongoDB, Memory, Mirror, Pool, Redis, plus the shared-tables and schemaless Mongo lanes
  • Unit tests for Collection-only createCollection (CollectionValidationTest, CollectionModelTest, Mirror, CreateCollectionRace)
  • Two pooled-timeout regression tests in tests/unit/Adapter/PoolTest.php, both seen red before the fix:
    • setTimeout on a pooled handle no longer dials a connection just to answer hasFeature()
    • a timeout raised while pinned reaches a subclass that pins its connection elsewhere, which is what cloud does per coroutine
  • tests/unit/TenantIdentityTest.php pins PHP's tenant comparison to what _tenant INT UNSIGNED actually stores, checked against a real MySQL
  • PHPStan on the Collection-only facade sources, and Pint on the converted files
  • tests/unit/Documents/MetadataTenantInvalidationTest.php — with shared tables and tenant-per-document, a miss cached before provisioning does not outlive the collection being created, and a collection is readable (with the right attribute count) by its own writer after creation and after a schema change. Both cases fail without the fix, the second with NotFound: Collection not found
  • tests/unit/Documents/NegativeCacheEpochTest.php — a miss observed before a concurrent write rotates the epoch is not negative cached, and a miss with no concurrent write still is. Seen red before the fix (a $empty marker for webhooks:hook survived the read)
  • tests/unit/StatisticalAggregateContractTest.php — the SQL each of MySQL, MariaDB and Postgres generates for stddev() / variance() is the _POP form, and stddevSamp() / varSamp() are left alone. Seen red before the fix: Postgres emitted STDDEV("price") (sample) where MySQL emitted the identical text meaning population
  • AggregationTests::testStddevAndVarianceArePopulationOnEveryAdapter — fixed dataset, asserts the population value and asserts it is not the sample value, across the whole adapter matrix

Not verified

  • The join-alias scoping above is covered by unit tests only; the e2e adapter matrix exercises joined aggregation but not an undeclared alias, which is rejected before it reaches an adapter.
  • A bare (unqualified) attribute still bypasses the schema check while a join is present, because the joined collection's schema is not available to the validator. Closing that needs the joined schema threaded through Validator\Queries\Documents and its per-collection cache key — a separate change.

📝 Walkthrough

Walkthrough

Large refactor: Query delegates to utopia-php/query BaseQuery; adapters, traits, hooks, and new domain types/enums (Attribute, Index, Relationship, Capability, etc.) migrate to value-object and capability models; CI, Docker, and composer updated to use a local query path and Paratest.

Changes

Cohort / File(s) Summary
Composer & CI
composer.json, .github/workflows/tests.yml, Dockerfile, docker-compose.yml

Fix rollback index TTL default: should be 0, not 1, to match TTL semantics elsewhere.

Additionally, the Validator/Index.php:810 uses getAttribute('ttl', 0) as default.

Remove the ->value accessor to fix the unreachable readiness loop.

At line 1081, $type is an IndexType enum case (assigned from $index->type at line 44), but the comparison $type === IndexType::Unique->value compares an enum case object to its backing scalar value. This will never match in PHP—enum cases and their backing values are distinct types. As a result, the readiness loop is unreachable and the code never waits for unique indexes to be fully built.

The fix is to compare the enum case directly:

Fix
-            if ($type === IndexType::Unique->value) {
+            if ($type === IndexType::Unique) {

- Around line 45-65: The capabilities() method currently removes
Capability::Upserts from the $remove list which causes
supports(Capability::Upserts) to return false even though this class implements
SQLite-specific ON CONFLICT expressions and executeUpsertBatch(); fix by
removing Capability::Upserts from the $remove array (so Upserts is reported as
supported) and ensure any related logic in executeUpsertBatch() and
conflict-expression generation remains intact to be exercised when
supports(Capability::Upserts) is checked.

In `@src/Database/Mirror.php`:
- Around line 1074-1086: The setRelationshipHook method in Mirror currently
discards the caller's RelationshipHook by always installing a new
RelationshipHandler on the source/destination; instead, forward the provided
$hook (or null) directly to the underlying databases. In the
Mirror::setRelationshipHook(?RelationshipHook $hook) implementation replace the
calls that pass new RelationshipHandler($this->source)/new
RelationshipHandler($this->destination) with the original $hook (or null) so the
caller's custom RelationshipHook is preserved when calling
$this->source->setRelationshipHook(...) and
$this->destination->setRelationshipHook(...).
- Around line 321-333: The code calls Attribute::fromDocument($document) after
running filters in $this->writeFilters, but Filter::beforeCreateAttribute() can
return null to indicate the attribute should be skipped; update the blocks that
call beforeCreateAttribute (e.g., the loop using $this->writeFilters and the
code that assigns $filteredAttribute) to check if $document is null after the
loop and, if so, skip further processing (do not call Attribute::fromDocument) —
apply the same null-check/skipping logic to the other symmetric block that
processes attributes (the second occurrence mentioned around the attribute
handling).

Reviewed this PR for CRITICAL/HIGH/MEDIUM findings (bugs and CLAUDE.md compliance). 1 HIGH finding — a cross-tenant data-leak regression in the newly extracted TenantFilter hook. Details inline.

Other items considered and cleared:

  • Duplicate createIndex calls in SQLite.php:267-268 — no-op because createIndex has an explicit IF NOT EXISTS short-circuit (lines 438-449). Redundant but not a bug; CodeRabbit already flagged as a nit.
  • Mirror::addHook constructing fresh Relationships($this->source/destination) — the new hook is bound to the correct target database; not a clear regression.
  • Missing readonly on new Attribute/Index/Collection/Relationship value objects — AGENTS.md phrases this as a conditional preference ("readonly properties for immutable data"), not an enforced rule; the prior review cycle on this PR already dismissed the analogous ORM case.
  • Snake_case test_* method naming across ~30 new test files — widespread deliberate convention change for the refactor, not a discrete bug.
  • Bug scan across new Hook/**, adapters, traits, and validators — no high-confidence regressions found beyond the one flagged below.

CI healing — run 24884705670

Root-caused two undefined-constant errors introduced by the recent merge from main into feat-query-lib:

1. Unit Tests (3 errors) — Utopia\Database\Query::LOGICAL_TYPES

Query::shape() at src/Database/Query.php:161 references self::LOGICAL_TYPES, but the constant was never declared on the Query class (nor inherited from the base Utopia\Query\Query). This made testShape, testFingerprint, and testFingerprintNestedLogicalQueries all error on the first call into shape().

Fix:

  • Added private const LOGICAL_TYPES = [Method::And, Method::Or, Method::ElemMatch] — matches the logical methods already listed in toArray().
  • Added public const TYPE_ELEM_MATCH = 'elemMatch' (the fingerprint/shape tests construct new Query(Query::TYPE_ELEM_MATCH, ...) and it was also undefined).
  • Fixed $node->method . ':' . ... concatenations — $node->method is a Method enum, not a string; changed to $node->method->value.

2. Adapter Tests / Mirror (1 error) — Utopia\Database\Database::VAR_STRING

tests/e2e/Adapter/MirrorTest.php:330 still used the removed Database::VAR_STRING constant inside a raw new Document([...]) attribute definition. Every other test in this file already uses the new Attribute(key:, type: ColumnType::String, ...) form.

Fix: Converted that one usage to the Attribute(...) form to match the rest of the file.

Verification

  • vendor/bin/paratest --functional --processes 4 /usr/src/code/tests/unit1220 tests, 0 errors (was 3 errors).
  • vendor/bin/phpunit --filter 'QueryTest::(testShape|testFingerprint|testFingerprintNestedLogicalQueries)'4/4 pass.
  • PHPStan clean on the changed file.

Note on the Mirror test

With the VAR_STRING constant fixed, testCreateDocumentsSkipDuplicatesBackfillsDestination now runs past the attribute definition and exposes a separate, pre-existing issue on this branch: Database::skipDuplicates() does not propagate to the adapter, and SQL::createDocuments() calls $builder->insert() unconditionally instead of $builder->insertOrIgnore() when the flag is set. That's out of scope for a CI-healing fix (the reported error was VAR_STRING, which is resolved), but it's a real skipDuplicates feature gap that will surface once the adapter runs this test end-to-end. Left for a follow-up commit.

CI heal (run 24886550663)

Failure: Tests\E2E\Adapter\MirrorTest::testCreateDocumentsSkipDuplicatesBackfillsDestination

Utopia\Database\Exception\Duplicate: Document already exists
Caused by: PDOException SQLSTATE[23000]: 1062 Duplicate entry 'dup' for key '_uid'
  at src/Database/Adapter/SQL.php:638 (createDocuments)

Root cause: After merging main into feat-query-lib, skipDuplicates support was added to Adapter.php, Mongo.php, SQLite.php, Postgres.php, and Mirror.php, but the shared SQL path in src/Database/Adapter/SQL.php::createDocuments() was left calling $builder->insert() unconditionally. When Mirror::createDocuments() forwarded a batch to destination under skipDuplicates (to backfill rows that source had no-op'd via INSERT IGNORE), the destination ran a plain INSERT and threw 1062 on the pre-seeded row.

Fix: Route through the query builder's insertOrIgnore() when $this->skipDuplicates is true. The utopia-php/query builder already maps this to INSERT IGNORE INTO (MySQL/MariaDB), INSERT OR IGNORE INTO (SQLite), and INSERT … ON CONFLICT DO NOTHING (Postgres), so the single line change covers all SQL adapters.

-            $result = $builder->insert();
+            $result = $this->skipDuplicates ? $builder->insertOrIgnore() : $builder->insert();

Code Review — critical & warning findings fixed

Ran /skills:improve on the query-library core of this PR and resolved 7 CRITICAL / 4 WARNING findings across the recent-delta files. Full diff is large (340 files), so the review was scoped to Query.php, Validator/Query/*, and Validator/Queries.php — the PR's core extraction theme.

Dimension summary

  • Security / correctness: ColumnType::from() \ValueError, Filter switch missing 10 ColumnType cases, Order::addAggregationAliases schema mutation leak across requests, aggregate-method dispatch missing half of Method::isAggregate() (stddevPop, varPop, bitAnd/Or/Xor, …), toArray() crash on non-Query child of And/Or/ElemMatch, pre-existing fatal-on-load from incompatible LOGICAL_TYPES visibility and parse() signature drift with the base library.
  • Performance / maintainability: dead duplicate-schema-lookup block in Filter::isValidAttributeAndValues, nested-recursion over Union/UnionAll that are not filter containers, drift risk between shape() and toArray() using two different literals for the same set.

Test result delta

Before this commit, the branch could not load Utopia\Database\Query (fatal: narrowed visibility on LOGICAL_TYPES; incompatible parse() signature). Fixing those plus the groupForDatabase order-attributes regression dropped unit-test failures from 31 errors + 1 failure → 2 errors + 1 failure. The 3 remaining failures are environmental (PHPUnit Swoole class, xdebug + PHP 8.2 dynamic-property on DateMalformedStringException) and are not caused by this PR.

Not addressed (intentional — out of this cycle's scope)

  • DRY refactor of the 5 near-identical Aggregate/Distinct/GroupBy/Having/Join validator skeletons.
  • Single-pass restructure of Queries::isValid (currently parses strings twice — correctness-neutral).
  • Hoisting the per-value switch-built validator in Filter::isValidAttributeAndValues out of the foreach (performance-only).
  • Cycle-guard / node-count cap on Query::shape() (theoretical DoS — unlikely to be reachable in practice).

These are worth doing but are architectural and carry regression risk for a follow-up PR.

CI heal — follow-up (after local verification)

My first fix touched SQL::createDocuments() but locally the test still failed, surfacing two deeper layers of the same bug in the feat-query-lib merge:

  1. Database::skipDuplicates() never reached the adapter. The method set $this->skipDuplicates = true on the Database instance but Traits/Documents::createDocuments() never propagated that to $this->adapter->skipDuplicates(...). So even with insertOrIgnore() wired up in SQL.php, $this->skipDuplicates on the adapter was false at the moment of insert. Mirrors main's pattern: wrap each batch with $this->adapter->skipDuplicates($insert) when $this->skipDuplicates is set. Also declared the property on Database to avoid dynamic-property fragility.

  2. Permissions hook used plain INSERT. Even after the document INSERT IGNORE was a no-op, Hook/Permissions::afterDocumentCreate ran $permBuilder->insert() against _perms, hitting Duplicate entry 'dup-create-any' for key '_index1' when the destination already had those permissions. Piped a skipDuplicates: bool through WriteContext from SQL::buildWriteContext, and the hook now calls insertOrIgnore() when the context says so.

Local verification: MirrorTest — 653 tests, 10 761 assertions, 0 failures.

Files touched:

  • src/Database/Database.php — declare $skipDuplicates property
  • src/Database/Traits/Documents.php — propagate to adapter in createDocuments()
  • src/Database/Hook/WriteContext.php — add skipDuplicates field
  • src/Database/Adapter/SQL.php — set skipDuplicates in buildWriteContext
  • src/Database/Hook/Permissions.php — honour skipDuplicates in afterDocumentCreate

CI failure — root cause and fix

Failed run: #24887417627

What failed

Every adapter test job errored with:

Error: Undefined constant Utopia\Query\Schema\ColumnType::Serial

originating from src/Database/Validator/Query/Filter.php:174 — the per-value validator switch that the previous review-findings commit extended with ColumnType::Serial, ::BigSerial, and ::SmallSerial cases.

Why

Those three cases were added upstream in utopia-php/query commit d692372 (feat(schema): PostgreSQL SERIAL column types, 2026-04-23). Our composer.lock was still pinned to 3f57d89f (2026-03-26), which predates them. So composer install in CI resolved an older ColumnType enum without Serial, and the switch failed at runtime the first time any test exercised the Filter validator.

Fix

Ran composer update utopia-php/query to roll the pin forward to the current tip of feat-builder (5ca0401), which includes the SERIAL cases. Only composer.lock is changed — no code changes needed. Verified locally that the enum loads all three cases and Filter.php is reachable via autoload.

abnegate and others added 2 commits September 21, 2026 20:47
updateAttribute() only reached the adapter when the type, size, sign,
array flag or key changed, so turning an attribute optional updated the
stored definition and left the column alone. Postgres then kept the NOT
NULL it was created with and refused the null the definition now
allowed. MariaDB hid this for spatial types because the guard above
forces the alter on adapters without SpatialIndexNull, and its MODIFY
COLUMN resets nullability in passing.

The constraint gets its own adapter call rather than joining the alter
path, which would drag a required-only change through a column type
rewrite: Postgres casts datetime columns with TO_TIMESTAMP on the way,
and that only parses text, so a timestamp column fails outright.

Relaxing is the only direction applied. Tightening fails against rows
already holding null, and MySQL does not tighten on update either, so
required stays enforced where it already is, in the structure validator.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Pool names every adapter method it hands on, because __call cannot
implement an abstract one. relaxAttributeRequired is concrete on the
base adapter, so PHP resolved it there instead of routing it through
__call, and a pooled Postgres silently kept the constraint. Every caller
that runs through a pool, which is every server, saw the original bug.

Comment thread tests/unit/SQLFindTest.php
Main stopped trusting the relationship value in deleteSetNull, because a
delete can start from a document fetched without its relationships
populated: deleteDocuments passes the caller's queries to find(), and a
select turns population off, so the child rows were left pointing at a
deleted parent. The branch moved that code into the relationship hook,
so the fix lands there, keeping the batched updateDocuments the hook
already used rather than main's per-document loop.

Main's three regression tests come across on the query-lib API. Its
array-operator test for one to one is dropped: the branch already covers
that rejection in the unit validation suite, where the rest of the
relationship value checks moved.

Adopts main's lazy default-filter registration and its fix for spatial
decoding reaching the wrong adapter.

The filter registry is static but the spatial decode closures captured
$this, so every new Database silently rebound them to its own adapter —
a long-lived instance would decode through an unrelated adapter. The
decoders now use the $database argument the call site already passes,
which makes every default filter static and lets registration happen
once behind a guard rather than on each construction.

Main's perf refactor of the filter signatures is deliberately not taken:
this branch's filters accept (value, document, database, attribute), a
superset of main's (value, document, database), and splicing the two
produced a broken json decoder.

clearReferences() put every referencing document ID into one Query::equal

count was rejected by query validation before updateDocuments ran, and
the SetNull policy aborted instead of clearing the foreign keys.

Making it static to suit the now-unbound encode closures would be a
breaking change for a library: it is protected on a class downstream
repos subclass, and a subclass overriding it non-statically fatals at
class load.

The encode filters already receive the calling instance as their third
argument, same as decode, so take it there instead.

Comment thread tests/unit/CollectionModelTest.php
A join used to switch off aggregate and group-by schema validation wholesale,
so a qualified attribute naming an alias the query set never declared reached
the adapter as an invalid column. Alias-qualified references now have to match
a declared join alias and a single plain column segment, matching what the
select, filter and order validators already require; a bare name still passes
because the joined collection's schema never reaches the validator.

The shared join-column check moves to Base so the aggregate and group-by
validators can use it instead of a fourth copy.

The empty-document marker records that a key was absent as of the epoch
the read started under. A schema mutation landing while that read is in
flight rotates the epoch, which makes the observation stale, and nothing
stopped the marker being written anyway: saveWithLease leases the
document key's own generation, and a rotation never touches it.

Re-read the epoch immediately before the write and skip the marker when
it has moved. A miss with no concurrent mutation is still cached, so the
negative cache keeps doing its job.

Bare SQL STDDEV and VARIANCE are population on MySQL and MariaDB and
sample on PostgreSQL, so the same query answered 67.0238 on one engine
and 77.3985 on the other over the same four rows. The query library
emits the bare function verbatim, so the adapter is where the ambiguity
has to be resolved.

Population is the contract: it is what MySQL and MariaDB already
returned, what the query library's ClickHouse builder already chose, and
what leaves the existing stddevPop / varPop expectations intact. Callers
who want the sample statistic ask for it by name with stddevSamp() or
varSamp(), which were never ambiguous.

The negative-cache test read the memory adapter's $store and matched on
the stored payload shape, which made the cache's storage layout part of
the test. Counting the empty markers the database hands to
saveWithLease() asserts the same thing against the interface the
database actually calls, and drops the coupling.

Every SQL adapter created a `_version` column and wrote it on insert and
bulk update, but existing tables were created without it and nothing
added it, so the first write after upgrading failed on every install.
The compare-and-set built on it (expectedVersion on updateDocument and
deleteDocument, the Redis Lua scripts, the Mongo $inc pipeline) has no
consumer once Appwrite and the migration library move back to the
request-timestamp conflict check, so the whole feature goes rather than
gaining a fleet migration.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…tion

The query builder migration removed 91 tests instead of porting them to
the typed API. Bringing them back on Attribute, Index, Collection and
Relationship value objects surfaced four regressions the deleted tests
had been guarding:

- decode() left the SQL column alias of a dotted attribute on the
  document whenever the column was null, so a document exposed both
  `pb.e_DSS.FIRMWARE_VERSION` and `pbe_DSSFIRMWARE_VERSION`.
- The `$sequence` tie break was spliced in right behind a leading
  timestamp order, so a caller's second order key was never read.
- Renaming a document without changing its permissions skipped the
  permission sync, leaving the `_perms` rows keyed by the old id and
  the renamed document unreadable through the side table.
- A vector search carried a `$sequence` tie break even without a
  cursor, which pgvector cannot answer from the index, so every search
  read the collection in full.

Custom document type coverage returns as its own scope with the fixture
classes in Support, and the two Postgres planner guards return to the
Postgres test class.

utopia-php/database#823 gained two library fixes after the last re-pin --
the negative document cache no longer survives an epoch rotation, and
stddev/variance are pinned to the population statistic -- so CI here was
resolving a commit that predates both.

The index builder carried its own three-entry map of internal attribute
to column, so an index on $sequence reached SQLite as a bare `sequence`
and the create failed on a column that does not exist. Storage already
holds the full map every other adapter resolves through.

Mirror forwards every other configuration setter to the databases it
wraps, but not setCache, so replacing the cache rebound only the outer
instance. Reads still resolved through the source's original cache while
writes purged the new one, and an updated document kept reading back at
its previous value.

…s it

Under shared tables with tenant per document, every _metadata cache
invalidation was aimed at a key no reader ever used.

createDocument() purges through withDocumentTenant(), which switches to
the document's own tenant. A collection definition is the one row
createDocument() accepts without a tenant under tenant per document, so
that switch set the tenant to null and built the cache key with an empty
tenant segment, while every reader resolves the same entry under the
adapter's tenant. The epoch the writer rotated and the epoch the readers
held were different keys, so nothing a writer did could reach them.

Anything cached for a collection definition therefore survived its own
invalidation for the full 24h TTL: a stale schema after an attribute
change, and above all the empty-document marker, which turned a
collection read that missed once during provisioning into a permanent
"Collection not found" for every later request in that tenant.

Keep the adapter's tenant when the document carries none. Documents that
do carry one still purge under it, which is what the switch is for.

  • P2 Test Pins Adapter State tests/e2e/Adapter/Scopes/GeneralTests.php:728

    This assertion reaches through the public Database facade to check the adapter's internal transaction flag. The document read immediately afterward already verifies the observable requirement that the database remains usable after rollback. Pinning inTransaction() makes an equivalent internal refactor fail the test without breaking callers, violating the repository directive to test observable behavior rather than implementation details. This repository requirement must be satisfied before merging; verify through public operations that another transaction can begin and complete successfully.

    Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

A project with its own database runs sharedTables false, tenant null and
a namespace of its own, which is the configuration the maintenance sweep
is under when it reads a collection a project has not provisioned yet.
withDocumentTenant() never switches a tenant there, so the read key and
the rotated key agree for a different reason than they do under shared
tables. Pin it, so neither path can regress without the other noticing.
