- Backend: GET /api/v1/data-resources accepts parent_path; LIKE
'{ws_id}/%/{escaped}/%' AND NOT LIKE '{ws_id}/%/{escaped}/%/%' on
StorageObjects.object_key (workspace-wide, escapes _ and %, mirrors
list_scripts parent_path semantics). 13 new tests in
test_resources.py (helper unit / SQL compile / SQLite behavioral).
- Frontend: listResources gains parentPath arg, propagated through
WorkspaceBoundApi + AuthContext binding. WorkspaceTreeGroup title
count and ScriptExplorer header count now include dataResources.
memberScriptGroups backfills data-only owners so users with only
data resources still render a group. loadDataResources accepts an
optional parentPath, default empty preserves prior behavior.
Summary of changes:
- Resources Bind Idempotency (High 1+2):
- Check existing active storage object bindings before duplicate check.
- Return existing binding (`reused: true`) on retry with same upload_id.
- Filter by `status == "active"` to bypass dead/deleted rows during reuse check.
- Storage Concurrent Overwrite (High 3):
- Add `acquire_named_lock` and `release_named_lock` helpers using MySQL `GET_LOCK`/`RELEASE_LOCK` hashed to <= 64 chars.
- Wrap `upload_bytes_to_session` PUT+INSERT critical section with named lock on `object_key`.
- Re-check key collision inside lock; append ULID suffix on collision.
- Shared Reference Deletion Protection (Medium 4):
- Check active references before deleting storage objects in `delete_resource`.
- Delete only `DataResources` record if storage object is still referenced elsewhere.
- Robust Usage Type Fallback (Medium 5):
- Replace direct dict lookup for `USAGE_TYPE_TO_PURPOSE[item.usage_type]` with `.get(..., "workspace")` default.
- Idempotency Key Path Matching (Medium 6):
- Move `file_name`/`target_path` validation forward and include path dimension in comparison.
- Strip uniqueness suffix via `_strip_uniqueness_suffix` before key comparison to avoid false 409s on valid retries.
- Usage Type & Bind Concurrency Control (Low 7 & 8):
- Reject bind requests with 409 if upload session purpose is not `data_resource`.
- Wrap resource duplicate check and creation in named lock using `(owner, directory, name)`.
- Trash Key Uniqueness & Restore Compatibility (Low 9):
- Update `trash_key` format to `{purpose}/{object_key}-{storage_object_id}` to prevent collisions.
- Update `object_key_hash` on trash move.
- Update restore logic in `storage_api.py` to strip suffix while maintaining backward compatibility with legacy keys.
- Dead Code Removal (Low 10):
- Remove unreachable `upload_status = "failed"` and redundant `session.rollback()` in `IntegrityError` block.
- Tests & Mocks:
- Add/update 5 test cases covering non-data_resource bind rejection, suffix stripping, and path recovery.
- Add named lock statement mocks for DB testing.
