## Open Issues
-### `grails-datamapping-core` — GormEnhancerAllQualifiersSpec (15 failures)
-
-**Module**: `grails-datamapping-core`
-**Spec**: `org.grails.datastore.gorm.GormEnhancerAllQualifiersSpec`
-**Root cause**: Our O(M+N) refactor to `GormEnhancer.groovy` introduced two regressions.
-
-#### Failure Type A — NPE in constructor (3 tests)
-
-**Tests**:
-- `MultiTenant entity with default datasource expands to all qualifiers`
-- `MultiTenant entity with ALL datasource expands to all qualifiers`
-- `non-MultiTenant entity with ALL datasource expands to all qualifiers`
-
-**Cause**: `GormEnhancer.<init>` line 140 calls `getDefaultConnectionSource().getName()` but mock `ConnectionSources` doesn't stub `getDefaultConnectionSource()` → returns null → NPE.
-```
-java.lang.NullPointerException: Cannot invoke "ConnectionSource.getName()"
- because the return value of "ConnectionSources.getDefaultConnectionSource()" is null
- at GormEnhancer.<init>(GormEnhancer.groovy:140)
-```
-**Fix**: Guard with null-safe: `qualifier = cs.defaultConnectionSource?.name ?: ConnectionSource.DEFAULT`
-
-#### Failure Type B — Registry empty after `registerEntity` (2 tests × 3 forks = 6 failures)
-
-**Tests**:
-- `registerEntity adds static api under default and secondary for non-default datasource`
-- `registerEntity adds static api under default and secondary for MultiTenant entity`
-
-**Cause**: `registerEntity` iterates `this.connectionSourceNames` (which is `['DEFAULT']` for a plain mock datastore). An entity declaring `datasource 'secondary'` has its secondary qualifier listed in `ConnectionSourcesSupport.getConnectionSourceNames(entity)`, but `registerEntity` never iterates those — so `getDatastore(entity.name, 'secondary')` returns null.
-```
-GormRegistry.instance.getDatastore(entity.name, 'secondary') != null → false
-(registry is empty: staticApis=[:] datastoresByQualifier=[:] ...)
-```
-**Fix**: In `registerEntity`, after the main loop, also iterate over the entity's declared datasource qualifiers and call `registry.registerEntityDatastore(className, qualifier, datastore)` for each non-ALL qualifier.

(grails-core) 05/06: fix(test): make GormRegistryScalabilitySpec parallel-safe
Posted by bo...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
borinquenkid pushed a commit to branch 8.0.x-hibernate7_gorm_enhance
in repository https://gitbox.apache.org/repos/asf/grails-core.git
commit 02d9cb72c68a8f60992717d458ac2b547b59bcd9
Author: Walter Duque de Estrada <wb...@mac.com>
AuthorDate: Tue May 5 17:10:18 2026 -0500
fix(test): make GormRegistryScalabilitySpec parallel-safe
Replace absolute staticApis/instanceApis/validationApis size bounds with
entity-scoped key counts. The previous assertions (size() < 2 * TENANT_COUNT)
assumed a clean GormRegistry singleton, but in parallel test execution other
test classes register their own entities, inflating the total count.
New assertion: count only the keys belonging to our two test entities and
verify it equals exactly 2 (one per class, not one per tenant). This correctly
proves the O(M) guarantee without being sensitive to parallel test pollution.
Applied to both:
- grails-datamapping-core-test GormRegistryScalabilitySpec
- grails-data-hibernate7 GormRegistryScalabilitySpec

(grails-core) 01/06: test(h7): add GormRegistryScalabilitySpec to verify O(M+N) memory guarantee
Posted by bo...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
borinquenkid pushed a commit to branch 8.0.x-hibernate7_gorm_enhance
in repository https://gitbox.apache.org/repos/asf/grails-core.git
commit 1ddb6039a788096a9ce0a4a2f47e3ead68896638
Author: Walter Duque de Estrada <wb...@mac.com>
AuthorDate: Tue May 5 14:31:08 2026 -0500
test(h7): add GormRegistryScalabilitySpec to verify O(M+N) memory guarantee
Verifies that GormRegistry maintains the O(M+N) memory contract
in the H7 SCHEMA multi-tenancy context:
- O(M): staticApis/instanceApis/validationApis maps have one entry
per entity class — never multiplied by tenant count
- O(N): datastoresByQualifier grows with tenants (one entry per qualifier)
- O(1): same singleton API instance returned for any qualifier
- No spurious entries: unknown-qualifier lookup does not pollute the map
- Smoke test: all 5 SCHEMA child datastores are reachable by tenant ID
Uses HibernateDatastore with SCHEMA multi-tenancy and a fixed
AllTenantsResolver (schemaA–schemaE), parallel to the approach
used in SchemaTenantGormEnhancerSpec.

+
+**Cause**: `registerEntity` iterates `this.connectionSourceNames` (which is `['DEFAULT']` for a plain mock datastore). An entity declaring `datasource 'secondary'` has its secondary qualifier listed in `ConnectionSourcesSupport.getConnectionSourceNames(entity)`, but `registerEntity` never iterates those — so `getDatastore(entity.name, 'secondary')` returns null.
+```
+GormRegistry.instance.getDatastore(entity.name, 'secondary') != null → false
+(registry is empty: staticApis=[:] datastoresByQualifier=[:] ...)
+```
+**Fix**: In `registerEntity`, after the main loop, also iterate over the entity's declared datasource qualifiers and call `registry.registerEntityDatastore(className, qualifier, datastore)` for each non-ALL qualifier.

fix: repair GormEnhancer regressions from O(M+N) refactor
Fix two regressions in GormEnhancer introduced by the O(M+N) GormRegistry
refactor that broke all 15 tests in GormEnhancerAllQualifiersSpec.
Fix A — NPE in constructor (Type A):
GormEnhancer.<init> line 140 called getDefaultConnectionSource().getName()
directly. When the ConnectionSources mock doesn't stub getDefaultConnectionSource()
the call returns null and NPEs. Added null-safe navigation:
qualifier = ...connectionSources?.defaultConnectionSource?.name ?: ConnectionSource.DEFAULT
Fix B — registry empty after registerEntity (Type B):
registerEntity looped only over this.connectionSourceNames (set from the
enhancer's own datastore, typically [DEFAULT] for a plain mock). Entities
that declare a named datasource via `datasource 'secondary'` had their
qualifier in ConnectionSourcesSupport.getConnectionSourceNames(entity) but
that loop was never visited, so getDatastore(entity.name, 'secondary')
returned null. Added a second loop after the main one that iterates the
entity's declared non-DEFAULT/non-ALL qualifiers and registers them via
registry.registerEntityDatastore(className, entityQualifier, datastore).
All 253 grails-datamapping-core tests now pass.

(grails-core) 02/06: test(core): add GormRegistryScalabilitySpec to verify O(M+N) memory guarantee
Posted by bo...@apache.org.

borinquenkid pushed a commit to branch 8.0.x-hibernate7_gorm_enhance
in repository https://gitbox.apache.org/repos/asf/grails-core.git
commit 1be3415729868340a14da269a96d0f26bda1b7c1

test(core): add GormRegistryScalabilitySpec to verify O(M+N) memory guarantee
Adapts the H7 GormRegistryScalabilitySpec for grails-datamapping-core-test
using SimpleMapDatastore in DATABASE multi-tenancy mode.
Verifies the O(M+N) contract of GormRegistry:
- O(M): staticApis/instanceApis/validationApis each bounded by entity count,
never multiplied by tenant count
- O(N): datastoresByQualifier grows with tenants (default qualifier present)
- O(1): same singleton API returned for any qualifier
- No pollution: unknown-qualifier lookup does not insert spurious map entries
- Data isolation smoke test: tenant_write data not visible in tenant_read
Key difference from H7 variant: uses SimpleMapDatastore + DATABASE tenancy
and passes TenantResolver as an instance (not a class reference) to avoid
Spring ConverterNotFoundException during PropertyResolver conversion.
