Walkthrough

Two new migration scripts create tables for hierarchical data using nested sets, with conditional column types for different database drivers. Test setup is refactored to centralize migration execution via a new helper method, and a stub migration controller is introduced to override output handling during tests.

Changes

File(s) Change Summary
migrations/m250707_103609_tree.php, migrations/m250707_104009_multiple_tree.php Added migrations to create tree and multiple_tree tables for nested sets with DB driver-specific column types and indexes.
tests/TestCase.php Refactored test setup to use centralized runMigrate() helper for applying migrations; updated imports accordingly.
tests/support/stub/EchoMigrateController.php Added EchoMigrateController stub class overriding stdout method for test output capture.

Poem

In the warren of code, a new tree takes root,
With migrations that nest, and tests that reboot.
Echoes of structure, deep in the night,
Rabbits delight as their tables take flight.
Hopping through schemas, with paws full of glee,
🐇 Nested sets flourish—oh, what a spree!

🔇 Additional comments (4)
tests/TestCase.php (4)

12-12: LGTM: Import addition is appropriate.

The Query class import is correctly added to support the enhanced database operations in the refactored code.


14-14: LGTM: EchoMigrateController import is necessary.

The import correctly references the stub controller needed for the new migration-based database setup.


173-191: Excellent refactoring to migration-based database setup.

The method has been properly refactored to use migrations instead of manual schema creation, which:

  • Ensures consistency with the new migration files
  • Provides better maintainability and version control
  • Handles rollback scenarios gracefully with the try-catch block

The implementation correctly handles edge cases where migrations might not exist initially.


389-415: Robust migration helper method with enhanced error handling.

The runMigrate method implementation addresses the past review comment's concern about error handling, but with improvements:

  • Uses type-safe checking with is_int($result) && $result !== 0
  • Captures output buffer content and includes it in error messages
  • Provides detailed error information for debugging

This implementation is more robust than the previously suggested approach as it handles non-integer return values and provides comprehensive error context.

migrations/m250707_103609_tree.php (1)

27-30: Optimize nested set index strategy.

The current indexing strategy is good but could be enhanced. Consider adding a composite index on (lft, rgt, depth) for better query performance in complex nested set operations.

 $this->createIndex('idx_tree_lft', '{{%tree}}', 'lft');
 $this->createIndex('idx_tree_rgt', '{{%tree}}', 'rgt');
 $this->createIndex('idx_tree_depth', '{{%tree}}', 'depth');
 $this->createIndex('idx_tree_lft_rgt', '{{%tree}}', ['lft', 'rgt']);
+$this->createIndex('idx_tree_lft_rgt_depth', '{{%tree}}', ['lft', 'rgt', 'depth']);
migrations/m250707_104009_multiple_tree.php (1)

21-21: Document the rationale for nullable tree column.

The tree column is nullable, which might be intentional for supporting root nodes or default trees. Consider adding a comment explaining this design decision.

-'tree' => $this->integer()->null(),
+'tree' => $this->integer()->null(), // Nullable to support default tree (null = tree 0)

tests/support/stub/EchoMigrateController.php (1)

11-16: stdout override signature is compatible with parent Controller

The stub’s public function stdout($string) exactly matches the signature in yii2/console/Controller.php and its boolean return value is acceptable in tests. No changes required.

migrations/m250707_103609_tree.php (1)

11-17: Excellent database-specific handling.

The Oracle-specific primary key and column type handling is well-implemented. The 4000-character limit for Oracle strings is appropriate for the VARCHAR2 limitations.

tests/TestCase.php (2)

172-174: Excellent refactoring to use migrations.

The migration-based approach is much cleaner and more maintainable than manual schema creation. This ensures tests use the same schema as production.


310-310: Migration path resolution confirmed
The migrationPath setting (dirname(__DIR__) . '/migrations') correctly points to the existing migrations/ directory at the project root. No changes needed.

migrations/m250707_104009_multiple_tree.php (2)

28-32: Excellent index strategy for multiple trees.

The indexing strategy properly supports multiple tree operations with individual indexes on key columns and a composite index on (tree, lft, rgt) for optimal query performance.


11-17: Consistent database-specific handling.

The Oracle-specific handling is consistent with the tree migration, maintaining code consistency across migrations.
