Add `subresources/types.go` with `NameTruncator`, `LabelManager` -3. Add `subresources/utils.go` with shared utilities -4. Update `subresources/getter.go` to add `GetSubResourceAdapter()` function - -### Phase 2: Implement PVC Adapter with New Interface - -1. Add `subresources/pvc_adapter.go` implementing both interfaces -2. Add `subresources/subresource_control.go` generic control -3. Update existing `pvc_control.go` to use new utilities internally - -### Phase 3: Integration - -1. Update `xset_controller.go` to use new `SubResourceControl` -2. Keep old `SubResourcePvcAdapter` path for backward compatibility -3. Prefer new `SubResourceAdapterGetter` if implemented - -### Phase 4: Example Implementation - -1. Add `subresources/service_adapter.go` as reference implementation -2. Update CLAUDE.md with new subresource documentation - -## Backward Compatibility - -| XSetController Implements | Behavior | -|--------------------------|----------| -| Neither interface | No subresource management | -| `SubResourcePvcAdapter` only | Uses old `PvcControl` (unchanged) | -| `SubResourceAdapterGetter` only | Uses new `SubResourceControl` | -| Both | Prefers new `SubResourceAdapterGetter` | - -## Testing Strategy - -1. **Unit Tests** - - `NameTruncator.Truncate()` with various name lengths - - `LabelManager.SetLabel()` with long values - - Hash uniqueness for truncated names - -2. **Integration Tests** - - PVC adapter with new interface - - Service adapter example - - Backward compatibility with old `SubResourcePvcAdapter` - -3. **E2E Tests** - - Create XSet with long names, verify truncation - - Update templates, verify subresource recreation - - Delete XSet, verify retention policy - -## Open Questions - -1. Should we add a `ValidateTemplates()` method to `SubResourceAdapter` for admission validation? -2. Should `NameTruncator` be configurable per resource type (e.g., 253 for ConfigMaps)? -3. Should we track original names in annotations for debugging purposes? - -## References - -- Kubernetes naming constraints: `k8s.io/apimachinery/pkg/util/validation` -- Existing PVC implementation: `subresources/pvc_control.go` -- Example implementations: - - ModelSet: `/Users/ana/projects/aicloud/modelops-controller/pkg/controllers/modelset/` - - LeaderSet: `/Users/ana/projects/aicloud/aether/pkg/controller/leaderworkerset/leaderset/` \ No newline at end of file diff --git a/docs/superpowers/specs/2026-04-16-configurable-naming-prefix-design.md b/docs/superpowers/specs/2026-04-16-configurable-naming-prefix-design.md deleted file mode 100644 index 81c5daa..0000000 --- a/docs/superpowers/specs/2026-04-16-configurable-naming-prefix-design.md +++ /dev/null @@ -1,245 +0,0 @@ -# Configurable Naming Prefix Design - -**Date:** 2026-04-16 -**Status:** Draft -**Author:** kube-xset team - -## Summary - -Add optional interface methods to allow controllers and adapters to customize target and subresource name prefixes.

synccontrols/x_utils.go: Restore DNS validation in GetTargetsPrefix - Re-add validation for controllerName prefix to ensure valid DNS subdomain 2. synccontrols/sync_control.go: Fix unused subresource deletion - Only delete unused subresources when target is being deleted or replaced - Active targets may still reference subresources no longer in spec - Update BatchDeleteTargetsByLabel doc comment to reflect current cleanup flow 3. subresource_control.go: Multiple safety improvements - setUpCacheForAdapters: Return explicit error when GVK not in scheme - deleteResource: Add TODO comment about finalizer removal trade-offs - DeleteTargetUnusedResources: Add IMPORTANT doc comment about when to call 4. subresource_control_test.go: Remove empty placeholder tests - Remove table-driven tests with
