From 8884d2d1e48677342560e3b45537bca9ba99fa25 Mon Sep 17 00:00:00 2001 From: Andreas Marek Date: Wed, 28 Jan 2026 09:40:42 +1000 Subject: [PATCH 1/9] Consolidate 31 validation rule classes into single OperationValidator Replace the AbstractRule + RulesVisitor + 31 individual rule class architecture with a single OperationValidator class that implements DocumentVisitor directly. BREAKING CHANGE: The rule filtering predicate type changes from Predicate> to Predicate in Validator, ParseAndValidate, and GraphQL. Code that filters validation rules by class reference must migrate to the new OperationValidationRule enum. - Create OperationValidationRule enum with 31 values (one per rule) - Create OperationValidator implementing DocumentVisitor with all validation logic consolidated from the 31 rule classes - Simplify Validator to create OperationValidator directly - Update ParseAndValidate and GraphQL predicate types - Delete AbstractRule, RulesVisitor, and all 31 rule classes (keep VariablesTypesMatcher as utility) - Convert all test files from mock-based rule instantiation to integration tests or OperationValidator with rule predicates - Update JMH benchmarks Co-Authored-By: Claude Opus 4.5 --- .../OverlappingFieldValidationBenchmark.java | 10 +-

00:00:00 2001 From: Andreas Marek Date: Wed, 28 Jan 2026 10:58:03 +1000 Subject: [PATCH 3/9] Move VariablesTypesMatcher and all validation tests from rules sub-package to validation package The rules sub-package is no longer needed since all 31 rule classes were consolidated into OperationValidator. Move the remaining utility class (VariablesTypesMatcher) and all 32 test files into the parent graphql.validation package, then delete the empty rules directories. Also remove stale JSpecifyAnnotationsCheck entries for deleted rule classes and update comments referencing the old package.

Rule Categories by Traversal Behavior

+ * + *

The {@link OperationValidator} tracks two independent state variables during traversal: + * {@code fragmentRetraversalDepth} (0 = primary traversal, >0 = inside fragment retraversal) + * and {@code operationScope} (true = inside an operation, false = outside). + * + *

This creates three possible traversal states: + *

Traversal Model

+ * + *

This validator tracks two independent state variables during traversal: + * + *

    + *
  • {@code fragmentRetraversalDepth} - Tracks whether we are in the primary document + * traversal ({@code == 0}) or inside a manual re-traversal of a fragment via a spread + * ({@code > 0}).
    • + *
  • {@code operationScope} - Tracks whether we are currently inside an operation + * definition ({@code true}) or outside of any operation ({@code false}).
    • + *
+ * + *

Traversal States

+ * + *

These two variables create four possible states, but only three actually occur: + * + *

Document-Level Rules

+ *

Check: {@code fragmentRetraversalDepth == 0} (via {@link #shouldRunDocumentLevelRules()}) + *

Purpose: Validate each AST node exactly once. Skip during fragment retraversal to avoid + * duplicate errors (the fragment was already validated at document level). + *

Examples: {@code FieldsOnCorrectType}, {@code UniqueFragmentNames}, {@code ScalarLeaves} + * + *

Operation-Scoped Rules

+ *

Check: {@code operationScope == true} (via {@link #shouldRunOperationScopedRules()}) + *

Purpose: Track state across an entire operation, including all fragments it references. + * These rules need to "follow" fragment spreads to see variable usages, defer directives, etc. + *

Examples: {@code NoUndefinedVariables}, {@code NoUnusedVariables}, {@code VariableTypesMatch} + * + *

Traversal Example

+ * + *

Consider this GraphQL document: + * 

{@code
+ * query GetUser($id: ID!) {
+ *   user(id: $id) {
+ *     ...UserFields
+ *   }
+ * }
+ *
+ * fragment UserFields on User {
+ *   name
+ *   friends {
+ *     ...UserFields   # recursive spread
+ *   }
+ * }
+ * }
+ * + *

The traversal proceeds as follows: + * + * 

+ * STEP  NODE                        depth  operationScope  DOC-LEVEL  OP-SCOPED
+ * ────  ──────────────────────────  ─────  ──────────────  ─────────  ─────────

+ * + *

Key Observations

+ * + *
    + *
  • Steps 6-9: During retraversal, document-level rules SKIP because the fragment + * will be validated at steps 11-14. This prevents duplicate "field not found" errors.
    • + *
  • Steps 6-9: Operation-scoped rules RUN to track that variables used inside + * {@code UserFields} are defined in the operation.
    • + *
  • Steps 11-14: Operation-scoped rules SKIP because there's no operation context + * to track variables against.
    • + *
  • Step 9: Recursive fragment spreads are tracked via {@code visitedFragmentSpreads} + * to prevent infinite loops during retraversal.
