(grails-core) 02/02: fix: correct DATABASE multi-tenant routing for @Service and @CurrentTenant
This is an automated email from the ASF dual-hosted git repository.
borinquenkid pushed a commit to branch worktree/fix-tenant-routing
in repository https://gitbox.apache.org/repos/asf/grails-core.git
commit ed62f8d4ae19413b25723f9610b8ff9717dfac93
Author: Walter Duque de Estrada <wb...@mac.com>
AuthorDate: Fri Jun 26 22:37:48 2026 -0500
fix: correct DATABASE multi-tenant routing for @Service and @CurrentTenant
When @CurrentTenant is combined with @Service(Book) in DATABASE multi-tenancy
mode, TenantTransform was calling findDatastore(domainClass) which resolved
the current tenant and returned a child datastore (e.g. child_foo). This
caused DefaultTenantService.withCurrent() to call Tenants.withId(child_foo)
which fails because child_foo only knows its own single connection.
- GormApiResolver: add findRootDatastore(Class) — direct DEFAULT-qualifier
lookup that bypasses tenant resolution, returning the parent datastore
- TenantTransform: use findRootDatastore() instead of findDatastore() for
@Service classes so TenantService always gets the multi-connection parent
- AbstractGormApi.execute(): for DATABASE mode with a non-default qualifier,
skip Tenants.withId() (which would try withNewSession on the child) and
call DatastoreUtils.execute(ds, callback) directly — the @CurrentTenant
wrapper already opened the correct child session on the parent
- Remove stale @PendingFeature from PartitionMultiTenancySpec (now passes)
- Add @PendingFeature to 3 ServiceTransformSpec tests where single-quoted
HQL strings bypass compile-time @Query validation (not yet implemented)
- Fix TenantContextProfilingSpec DummyStaticApi constructor (5-arg form)
