Database::createIndex catches that and silently registers the index as an "orphan" — matching MariaDB+Database's end-state where the metadata exists but the physical index does not. - Query::TYPE_SELECT now applies projection: find/getDocument restrict user attributes to the requested set while preserving internal columns ($id, $sequence, $createdAt, $updatedAt, $permissions, $tenant). - deleteDocuments now skips rows that don't belong to the current tenant in shared-tables mode, preventing cross-tenant destruction when auto-incrementing sequences collide between tenants. - getSequences uses each document's own tenant when building the lookup key (mirroring MariaDB's :_tenant_$i bind), instead of always using the adapter's current tenant. Documents with sequences already set are skipped to match the SQL contract. - find sorts by _id ASC by default to mirror MariaDB's clustered-index ordering, so paginating without an explicit order is stable. - count(max:0) and sum(max:0) honour zero (LIMIT 0 returns no rows on MariaDB) instead of treating any non-positive max as "no limit". - increaseDocumentAttribute returns true on bound violations (silent no-op) — MariaDB encodes the bound check in WHERE so the UPDATE just matches zero rows but the call still returns true. - rowToDocument no longer JSON-sniffs string values that happen to start with [ or { (which would inadvertently parse user-stored JSON-shaped strings on read). Array decoding is delegated to the Database layer's casting step; getSupportForCasting now returns true so arrays round-trip through Database::casting like the SQL adapters. - enforceUniqueIndexes type-normalizes signatures (booleans → ints, numeric strings → numbers, arrays → JSON-encoded) so a doc value of `true` matches a stored row value of `1`. - applyOrdering shuffles up-front when ORDER_RANDOM is requested instead of returning random_int(-1,1) inside usort — that comparator is non-transitive and breaks the sort. Each behavior change ships with a regression test in MemoryTest.

Inherits all 13 scope traits (Collection, Document, Attribute, Index, Operator, Permission, Relationship, Spatial, Schemaless, ObjectAttribute, Vector, General, CustomDocumentType); scope tests gated by getSupportFor* flags self-skip for the unimplemented features (relationships, operators, vectors, spatial, fulltext, schemaless, object attributes). Seven inherited tests are explicitly skipped via markTestSkipped where the surrounding trait does not gate on a flag (relationship-specific permission/order tests, upsert-with-JSON, attribute-name-with-dots, attribute structural type-coercion on resize, varchar truncation on shrink, and a no-op keyword test). Memory-specific regressions (transaction nesting, raw store layout after attribute operations, tenant isolation under shared tables, sequence resolution from per-document tenant) stay as direct tests, but route through a `freshDatabase()` helper so they cannot leak collections into the shared `getDatabase()` instance the inherited scopes use. Adapter parity tweaks unblocked by the broader coverage: - createDocument honours the per-call skipDuplicates flag (mirrors MariaDB INSERT IGNORE); - delete(name) only purges the namespace if the database flag was actually set, so a stray drop of a sibling schema (e.g. testEvents' hellodb) no longer wipes METADATA; - increase/decrease bound checks compare the pre-update column value (matching MariaDB's WHERE-clause semantics) instead of the post-update value; - documentKey lower-cases the id, matching MariaDB's default case-insensitive collation; - getDocument honours Query::select projection, dropping unselected user columns while preserving internals; - getMaxIndexLength returns 1024 (Mongo's value) so callers that derive sizes via `getMaxIndexLength() - N` arithmetic don't go negative; - getSupportNonUtfCharacters reports false (Memory does not actively reject non-UTF byte sequences); - TYPE_CONTAINS / TYPE_CONTAINS_ANY against scalar strings use stripos for MariaDB-compatible case-insensitive substring matching; - TYPE_CONTAINS_ANY and TYPE_CONTAINS_ALL are implemented for arrays. 647 tests now run against Memory, of which 25 are skipped (relationships, operators, vectors, spatial, fulltext, regex, schemaless plus the seven Memory-specific gaps); 2447 assertions all pass.

Storage keys are prefixed with the current database name so two databases under the same namespace stay isolated, mirroring MariaDB's CREATE DATABASE behaviour. Honour the metadata-collection NULL-tenant fallback under shared tables (parity with SQL.php's `OR _tenant IS NULL` clause), and persist each document's own tenant rather than the adapter's current tenant so tenantPerDocument writes land on the right partition.

Numeric overflow is detected via remaining-headroom comparison rather than naive addition — preserves int-ness near PHP_INT_MAX so the Range validator still accepts the result. Skip the upsert+operator scope tests in MemoryTest because Memory does not implement upserts.

Reads now surface registered relationship keys as null when unpopulated, matching MariaDB's `ADD COLUMN ... DEFAULT NULL` semantics so the wrapper can populate, traverse, and remove relationships consistently across drivers. updateDocument now applies a sparse merge against the existing row instead of replacing it wholesale, so the wrapper's pattern of removing unchanged relationship attributes before update no longer clobbers stored FKs. resolveAttributeValue tries the fully-filtered column name before falling back to dot-path traversal so relationship keys whose names contain dots (e.g. `\$symbols_coll.ection3`) match the row's flattened column. Cascade and metadata orchestration continue to live in the Database wrapper; the adapter only mutates the underlying row maps.

From 30ae71f5198b1fe7e2382f83a178450c6bc3f08e Mon Sep 17 00:00:00 2001 From: Jake Barnby Date: Wed, 29 Apr 2026 17:48:56 +1200 Subject: [PATCH 14/18] perf(memory): drop full-dataset snapshots and per-row scans MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the algorithmic hot spots flagged in the perf audit. Each change moves a hot path from O(dataset) or O(N) to O(touched) or O(1) per write, with the suite runtime dropping ~30% locally (42s → 29s) and assertion count unchanged at 4623. - Transactions: replace `unserialize(serialize($data))` snapshots with a per-transaction mutation journal. Every mutating entry point records its inverse op; `commit` discards the active journal, `rollback` walks it in reverse. Cost becomes O(touched rows) instead of O(dataset) per startTransaction, and nested transactions no longer multiply the copy. - Permissions: maintain `permissionsByDocument` and `permissionsByPermission` inverted indexes alongside the flat list. `applyPermissions` now intersects the user's roles against the permission map (O(roles × matched-buckets)) instead of walking the whole list per query. Per-document deletion in updateDocument / updateDocuments / deleteDocument / deleteDocuments is O(|that doc's perms|) instead of O(P). - Unique indexes: maintain `uniqueIndexHashes` keyed by index + signature. enforceUniqueIndexes is a hash probe, not a full scan; updateDocuments batch path drops the per-row sibling array_filter and detects sibling collisions while building a single pending-sig map (O(M·K) vs O(M·K·(N+K))). - Find pipeline: fuse tenantFilter / applyQueries / applyPermissions into a single pass that allocates one output array. Ordering and cursoring stay separate (they need the full set materialised), but the no-order path skips sorting and trusts insertion order. - Array attributes round-trip natively now — no more JSON encode-on-write / decode-per-access. resolveAttributeValue and decodeArrayValue collapse to pass-through for already-decoded arrays. - applyOrdering precomputes column mapping outside the usort closure and uses a decorate-sort-undecorate transform so the comparator only sees small key tuples. - Memory overrides Adapter::filter() with a per-instance cache so the preg_replace inside the find inner loop runs once per unique raw input, not once per row × per attribute. --- src/Database/Adapter/Memory.php | 1257 +++++++++++++++++++++++-------- 1 file changed, 947 insertions(+), 310 deletions(-) diff --git a/src/Database/Adapter/Memory.php b/src/Database/Adapter/Memory.php index 6ad3bb841..a492d163e 100644 --- a/src/Database/Adapter/Memory.php +++ b/src/Database/Adapter/Memory.php @@ -40,11 +40,46 @@ class Memory extends Adapter protected array $permissions = []; /** - * Transaction savepoint stack.
