modules/gql/gqlgen/schema.resolvers.go (1)

1-100: Consider implementing resolvers incrementally with proper testing

Given the scope of the GraphQL API, consider:

  1. Implementing resolvers incrementally, starting with core functionality
  2. Adding comprehensive integration tests for each resolver
  3. Implementing proper error handling and logging
  4. Adding rate limiting and authentication middleware
  5. Setting up monitoring for resolver performance

Would you like assistance in:

  1. Setting up a testing framework for the resolvers?
  2. Implementing middleware for authentication and rate limiting?
  3. Creating a monitoring setup for GraphQL operations?
modules/gql/gql.go (1)

20-20: Consider making the server port configurable

The server currently uses a hardcoded default port "8080", with no option to change it. Consider allowing the port to be configurable, either through function parameters, environment variables, or configuration files, to enhance flexibility in different deployment environments.

As a suggestion, you could modify the New function to accept a port parameter:

-func New() *gqlManager {
+func New(port string) *gqlManager {
     return &gqlManager{
-        port: defaultPort,
+        port: port,
         stop: make(chan struct{}),
     }
 }

Then, callers of New can specify the desired port. Additionally, you might provide a default value if no port is provided.

31-37: Remove Unused 'TransactionType' Enum

The TransactionType enum is defined but doesn't appear to be used anywhere in the schema. If it's not required, consider removing it to keep the schema clean. If it should be used, ensure that relevant fields reference it.

Apply this diff to remove the unused enum:

-enum TransactionType {
-  NULL
-  INPUT
-  OUTPUT
-  VIRTUAL
-  CORE
-}

67-68: Consider Defining Enums for 'op' and 'action' Fields

The op and action fields in TransactionData are of type String! and String, respectively. If these fields have a predefined set of possible values, defining enums for them would enhance type safety and ensure valid input values.


92-95: Standardize Field Name Casing in 'Gas' Type

The field IO in the Gas type is uppercase. For consistency with the snake_case convention used elsewhere, consider renaming it to io.

Apply this diff:

type Gas {
- IO: Int
+ io: Int
}

101-107: Avoid Using 'JSON' as Return Type in 'ContractState'

The state, stateQuery, and stateKeys fields in ContractState return JSON. Defining specific object types for these fields would improve client usability and leverage GraphQL's type system.


228-236: Use Enum Type for 'byStatus' in 'FindTransactionFilter'

In the FindTransactionFilter input, byStatus is currently a String. Since TransactionStatus is an enum, changing byStatus to TransactionStatus enhances validation and type safety.

Apply this diff:

input FindTransactionFilter {
  byId: String
  byAccount: String
  byContract: String
- byStatus: String
+ byStatus: TransactionStatus
  byOpCategory: String
  byAction: String
  limit: Int
}

246-269: Provide Descriptions for Schema Types and Fields

Adding descriptions to types, enums, and fields enhances schema documentation and helps consumers understand the API without external references.

Example of adding descriptions:

"""
Represents a blockchain transaction with its details and status.
"""
type Transaction {
  id: String!
  status: TransactionStatus!
  // ...
}

🛠️ Refactor suggestion

⚠️ Potential issue

Test implementation needs significant improvements

The current test implementation has several issues that should be addressed:

  1. The test name is too generic. It should describe what's being tested.
  2. The select{} creates an infinite block with no way to validate server behavior.
  3. Missing cleanup with defer for proper resource management.
  4. No timeout context for server operations.
  5. No actual test assertions or validations.

Here's a suggested improvement:

-func Test(t *testing.T) {
+func TestGraphQLServerLifecycle(t *testing.T) {
+    // Create context with timeout
+    ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+    defer cancel()
+
+    // Initialize server
     g := gql.New()
+    defer func() {
+        if err := g.Stop(); err != nil {
+            t.Errorf("failed to stop server: %v", err)
+        }
+    }()
 
     err := g.Init()
     if err != nil {
         t.Fatal(err)
     }
-    _, err = g.Start().Await(context.Background())
+
+    // Start server
+    ready, err := g.Start().Await(ctx)
     if err != nil {
         t.Fatal(err)
     }
 
-    select {}
+    // Validate server is ready
+    if !ready {
+        t.Fatal("server failed to become ready")
+    }
 
-    err = g.Stop()
-    if err != nil {
-        t.Fatal(err)
-    }
+    // Add actual test cases here
+    t.Run("Basic Query", func(t *testing.T) {
+        // Test basic query functionality
+    })
+
+    t.Run("Error Handling", func(t *testing.T) {
+        // Test error scenarios
+    })
}

Additionally, consider adding these test improvements:

  1. Add test cases for different GraphQL operations
  2. Test error scenarios (invalid queries, server errors)
  3. Add integration tests with the actual schema
  4. Add benchmarks for performance-critical operations

💡 Codebase verification

GraphQL implementation is incomplete

The test file assumes a working GraphQL server, but the implementation is missing critical components:

  • While the schema is well-defined with comprehensive types and queries, the resolver implementation is empty (only contains a struct definition)
  • The test attempts to use Start() and Stop() methods, but there are no resolver implementations for any of the queries defined in the schema
  • The gqlgen configuration is properly set up, but the resolver implementations that should be in {name}.resolvers.go files are not present

Required implementations:

  • Query resolvers for all operations defined in schema (e.g., contractState, findTransaction, etc.)
  • The Start() and Stop() methods used in the test
  • Proper error handling for the GraphQL server lifecycle

⚠️ Potential issue

Critical: Core blockchain operations are unimplemented

The core blockchain operation resolvers (ContractStateDiff, ContractState, FindTransaction, FindContractOutput, FindLedgerTXs, SubmitTransactionV1) are all unimplemented. These are critical components for blockchain functionality.

Additionally, the SubmitTransactionV1 resolver should include proper transaction validation and security checks when implemented.

Consider implementing these resolvers in the following order of priority:

  1. Transaction submission and querying (SubmitTransactionV1, FindTransaction)
  2. Contract operations (ContractState, ContractStateDiff)
  3. Ledger operations (FindLedgerTXs, FindContractOutput)

Would you like assistance in implementing these resolvers with proper error handling and security checks?

⚠️ Potential issue

Critical: Account management operations are unimplemented

The account management resolver (GetAccountNonce) is unimplemented. This is crucial for transaction sequencing and preventing replay attacks.

When implementing GetAccountNonce:

  • Ensure thread-safe nonce management
  • Consider implementing nonce caching for performance
  • Add proper error handling for invalid accounts

🛠️ Refactor suggestion

Refactor witness-related resolvers to use concrete types

The witness-related resolvers (ActiveWitnessNodes, WitnessSchedule, WitnessActiveScore) return *string which is too generic. Consider using concrete types for better type safety and clarity.

Example refactor for ActiveWitnessNodes:

-func (r *queryResolver) ActiveWitnessNodes(ctx context.Context) (*string, error) {
+func (r *queryResolver) ActiveWitnessNodes(ctx context.Context) (*WitnessNodeList, error) {

This would require defining appropriate types in your schema:

type WitnessNodeList {
    nodes: [WitnessNode!]!
    timestamp: Time!
}

💡 Codebase verification

The stop channel is unused and can be safely removed

After analyzing the code, the stop channel in gqlManager is only initialized in the constructor and closed in the Stop() method, but it's never used for any coordination or signaling purposes. The server shutdown is handled entirely through the context and http.Server.Shutdown() mechanism.

  • Remove the stop channel field from gqlManager struct (line 28)
  • Remove the initialization in New() method
  • Remove the close(g.stop) call in Stop() method (line 90)
🔗 Analysis chain

Verify the usage of 'g.stop' channel

The stop channel in gqlManager is initialized and closed, but it is not used elsewhere in the provided code. If it's not being used to signal shutdown or coordinate goroutines, consider removing it to simplify the code.

Define Specific Return Types Instead of 'JSON' in Queries

Several queries return JSON, such as witnessSchedule, nextWitnessSlot, and witnessActiveScore. Defining specific return types enhances type safety and provides clear API contracts.

Consider defining new types for these queries:

type WitnessSchedule {
  // Define the fields here
}

type NextWitnessSlot {
  // Define the fields here
}

type WitnessActiveScore {
  // Define the fields here
}

Update the query fields accordingly:

type Query {
  // Other fields...
- witnessSchedule(height: Int): JSON
+ witnessSchedule(height: Int): WitnessSchedule
- nextWitnessSlot(self: Boolean): JSON
+ nextWitnessSlot(self: Boolean): NextWitnessSlot
- witnessActiveScore(height: Int): JSON
+ witnessActiveScore(height: Int): WitnessActiveScore

Use Enum Type for 'status' Field in 'Transaction'

The status field in the Transaction type is currently defined as String!. Since you have an enum TransactionStatus, consider changing the type to TransactionStatus! for better type safety and to enforce valid values.

Line range hint 63-63: Address the TODO comment regarding WASM command path.

The TODO comment indicates that the proper command path needs to be set for the WASM IPC initialization. This could affect the proper functioning of the WASM module.

Would you like me to help implement the proper command path configuration? I can:

  1. Review the WASM module requirements
  2. Propose a configuration structure
  3. Generate implementation code

Line range hint 63-82: Consider error handling for WASM initialization.

The WASM module initialization lacks error handling compared to other plugin initializations (like hive_blocks.New). This could lead to silent failures.

Consider adding error handling:

-	wasm := wasm_parent_ipc.New() // TODO set proper cmd path
+	wasm, err := wasm_parent_ipc.New() // TODO set proper cmd path
+	if err != nil {
+		fmt.Println("error initializing WASM IPC:", err)
+		os.Exit(1)
+	}

Line range hint 65-82: Consider structured plugin initialization.

The current approach of manually appending plugins could benefit from a more structured initialization pattern, especially as more plugins are added.

Consider creating a plugin registry or builder pattern:

type PluginRegistry struct {
    plugins []aggregate.Plugin
}

func NewPluginRegistry() *PluginRegistry {
    return &PluginRegistry{
        plugins: make([]aggregate.Plugin, 0),
    }
}

func (r *PluginRegistry) Register(p aggregate.Plugin) error {
    // Add validation if needed
    r.plugins = append(r.plugins, p)
    return nil
}

This would make plugin management more maintainable and allow for better error handling during initialization.


Line range hint 65-82: Consider GraphQL integration strategy.

As this PR introduces GraphQL schema support, consider how the GraphQL server will be integrated into the current plugin architecture. The plugin system provides a natural extension point for this integration.

Recommendations:

  1. Create a new GraphQL plugin that encapsulates the server initialization and schema registration
  2. Ensure the GraphQL resolvers have access to necessary plugin dependencies (e.g., vscDb, witnesses)
  3. Consider implementing a dependency injection system for plugins to share capabilities

Example plugin structure:

type GraphQLPlugin struct {
    db        *vsc.Database
    witnesses *witnesses.Witnesses
    // other dependencies
}

func NewGraphQLPlugin(db *vsc.Database, witnesses *witnesses.Witnesses) *GraphQLPlugin {
    return &GraphQLPlugin{
        db:        db,
        witnesses: witnesses,
    }
}

// Implement aggregate.Plugin interface

75-75: Document plugin initialization order dependencies

The GraphQL manager has been correctly added to the plugins slice, but it would be helpful to document any initialization order dependencies between plugins.

Consider adding a comment explaining the required plugin initialization order, for example:

 plugins := make([]aggregate.Plugin, 0)

+// Plugin initialization order:
+// 1. Configuration and database plugins must be initialized first
+// 2. Core service plugins (witnesses, blocks)

50-51: Remove or document tracing configuration

The commented tracing configuration should either be removed if not needed or documented with instructions on when and how to enable it.


54-55: Consider making API paths configurable

The GraphQL and sandbox endpoints are hardcoded. Consider making these paths configurable through the constructor or environment variables for better flexibility.

Example refactor:

 type gqlManager struct {
     server *http.Server
     Addr   string
-    stop   chan struct{}
+    apiPath    string
+    sandboxPath string

70-82: Add documentation and improve type safety for ContractOutput

The ContractOutput type uses generic JSON types and lacks documentation for complex fields.

Consider adding documentation and specific types:

"""
type ContractOutput {
  """
  Unique identifier for the contract output
  """
  id: String!
  
  """
  Block where this output was anchored
  """
  anchored_block: String
  
  # ... (add documentation for other fields)
  
  """
  Results of contract execution
  """
  results: [ContractResult!]! # Define specific type instead of [JSON]
  
  """
  Side effects produced during contract execution
  """
  side_effects: ContractSideEffects # Define specific type instead of JSON
}

"""
Represents a single contract execution result
"""
type ContractResult {
  # Define specific fields based on your needs
  status: String!
  data: JSON
}

264-271: Separate test and production schemas

The schema mixes test and production endpoints, which could lead to confusion and potential security issues.

Consider:

  1. Moving test types and operations to a separate schema file (e.g., schema.test.graphql)
  2. Using GraphQL directives or environment-based schema stitching to manage test endpoints
  3. Implementing proper production mutations for necessary operations

Example structure:

# schema.test.graphql
extend type Query {
  getCurrentNumber: TestResult
}

extend type Mutation {
  incrementNumber: TestResult
}

type TestResult {
  currentNumber: Int
}

18-20: Add documentation for the mock resolver state

The MockResolver struct should include documentation explaining its purpose and usage in tests.

+// MockResolver implements the GraphQL resolver interface for testing purposes.
+// It maintains a simple state counter that can be modified and queried through
+// GraphQL operations.
 type MockResolver struct {
     StateCounter int
 }

111-120: Add error handling and documentation to mutation resolver

The mutation resolver should include:

  1. Method documentation
  2. Error handling for potential edge cases (e.g., overflow)
+// mockMutationResolver implements mutation operations for testing purposes
 type mockMutationResolver struct {
     *MockResolver
 }

+// IncrementNumber increments the state counter and returns the new value
 func (m *mockMutationResolver) IncrementNumber(ctx context.Context) (*gqlgen.TestResult, error) {
+    // Check for potential integer overflow
+    if m.StateCounter == math.MaxInt {
+        return nil, fmt.Errorf("counter overflow")
+    }
     m.StateCounter++
     return &gqlgen.TestResult{
-        CurrentNumber: &m.StateCounter, // inc val
+        CurrentNumber: &m.StateCounter,
     }, nil
 }

💡 Codebase verification

🛠️ Refactor suggestion

Based on the gathered information, I can now provide the final response:

GraphQL server implementation needs configuration improvements

The current GraphQL implementation in modules/gql/gql.go confirms the concerns:

  • The server uses plain HTTP (ListenAndServe) without TLS support
  • No configuration struct exists for customizing server settings
  • Error handling exists for server shutdown but not for initialization
  • The address parameter is passed directly without validation

Consider implementing a configuration struct and TLS support:

type Config struct {
    Host     string
    Port     string
    UseTLS   bool
    CertFile string
    KeyFile  string
}

And modify the New and Init functions to use this configuration, adding proper TLS support through ListenAndServeTLS when enabled.

🔗 Analysis chain

Consider making GraphQL configuration more robust and configurable

The current GraphQL initialization has several areas for improvement:

  1. The endpoint address is hardcoded to "localhost:8080"
  2. No TLS/HTTPS configuration is provided
  3. Using default resolver without customization
  4. Missing error handling for server initialization

Consider refactoring to:

- gqlManager := gql.New(gqlgen.NewExecutableSchema(gqlgen.Config{Resolvers: &gqlgen.Resolver{}}), "localhost:8080")
+ config := gql.Config{
+   Host:     os.Getenv("GQL_HOST"),
+   Port:     os.Getenv("GQL_PORT"),
+   UseTLS:   true,
+   CertFile: os.Getenv("GQL_CERT_FILE"),
+   KeyFile:  os.Getenv("GQL_KEY_FILE"),
+ }
+ gqlManager, err := gql.New(gqlgen.NewExecutableSchema(gqlgen.Config{
+   Resolvers: &gqlgen.Resolver{
+     // Add custom resolvers here
+   },
+ }), config)
+ if err != nil {
+   fmt.Printf("Failed to initialize GraphQL server: %v\n", err)
+   os.Exit(1)
+ }

Let me gather more information about the GraphQL implementation to verify the concerns.

💡 Codebase verification

GraphQL endpoint requires security measures

The codebase analysis confirms the GraphQL implementation lacks essential security measures:

  • No authentication/authorization middleware is implemented
  • No query complexity limits beyond auto-generated configurations
  • No global rate limiting (only basic per-query limits)
  • No input validation middleware

Required security implementations:

  • Add authentication middleware to protect GraphQL endpoints
  • Configure query complexity analysis to prevent DoS attacks
  • Implement rate limiting at the server level
  • Add input validation middleware for all operations
🔗 Analysis chain

Verify GraphQL security measures

The addition of a GraphQL endpoint introduces new security considerations that should be addressed:

  1. Authentication/Authorization
  2. Query complexity/depth limits
  3. Rate limiting
  4. Input validation

Consider implementing:

  • Authentication middleware
  • Query complexity analysis
  • Rate limiting middleware
  • Input validation for all GraphQL operations

Let me analyze the results and generate additional verification scripts to check for security implementations.

The previous results showed mostly generated code and some auth-related data structures, but we need to verify if there are actual security implementations in place. These new scripts will help us check for middleware setup, rate limiting, and auth validations.


Let me analyze the results and generate one final verification script to check for any middleware implementations.

The previous results show:

  1. Basic GraphQL server setup without security middleware
  2. Query complexity configuration exists but appears to be auto-generated
  3. No authentication/authorization checks found
  4. Basic rate limiting through limit parameters in queries, but no global rate limiting

Let me check the server initialization to see if any security middleware is added there.

type Contract {
-  id: String
+  id: String!
  code: String
-  creation_ts: String
+  creation_ts: String! # ISO 8601 format
}

2-9: Consider performance and security implications of the file watcher

The current configuration might lead to performance issues and potential security risks:

  1. Running the entire application on every file change could be resource-intensive
  2. No debounce configuration could trigger multiple concurrent runs
  3. Automatic execution of code on file changes could be a security risk

Consider these improvements:

  1. Add a debounce setting to prevent rapid consecutive executions
  2. Limit the file watch pattern to specific directories
  3. Consider using go run . instead of main.go for better maintainability
  4. Add error handling for the command execution

Here's a suggested configuration:

 {
   "filewatcher.commands": [
     {
       "match": "\\.go$",
+      "exclude": "(test|\\.git)",
       "isAsync": true,
-      "cmd": "cd ~/go-vsc-node/cmd/vsc-node && go run main.go",
+      "cmd": "cd ${workspaceFolder}/cmd/vsc-node && go run . || echo 'Build failed'",

77-80: Implement proper witness scheduling mechanism

The WitnessSchedule resolver should include:

  • Deterministic witness selection
  • Time-based rotation logic
  • Conflict resolution for competing witnesses

107-114: Consider adding context handling in resolver implementations

The resolver implementations could benefit from:

  • Request context validation
  • Request tracing/logging
  • Rate limiting middleware

Example enhancement:

 func (r *Resolver) Query() QueryResolver { 
+    // Add request context validation
+    // Add request tracing
+    // Add rate limiting
     return &queryResolver{r} 
 }

10-12: Strengthen 'Contract' Type Field Requirements

The Contract type has all optional fields, which could lead to data inconsistency issues. Consider making critical fields required to ensure data integrity.


33-33: Use Enum Type for 'status' Field in 'Transaction'

The status field in the Transaction type is currently defined as String!. Since you have an enum TransactionStatus, consider changing the type to TransactionStatus! for better type safety and to enforce valid values.


200-205: Clarify Field Names in 'LedgerOp' Type

Fields t, tk, and idx in the LedgerOp type are not descriptive. Renaming them to more meaningful names will improve readability and maintainability.


256-259: Define Specific Return Types Instead of 'JSON' in Queries

Several queries return JSON, such as activeWitnessNodes, witnessSchedule, nextWitnessSlot, and witnessActiveScore. Defining specific return types enhances type safety and provides clear API contracts.


259-259: Remove 'mockGenerateElection' from Production Schema

The mockGenerateElection field appears to be a mock function. Including mock functions in the production schema may expose unintended functionality. Consider removing it or ensuring it's appropriately secured and documented.

24-26: Remove Unused 'stop' Channel in 'gqlManager' Struct

The stop channel in the gqlManager struct is initialized but not utilized for coordination or signaling within the code. Removing it can simplify the codebase.


66-78: Refactor 'Start' Method to Use Idiomatic Go Concurrency Patterns

The Start method currently uses the github.com/chebyrash/promise package for asynchronous operations, which is not idiomatic in Go. It's conventional to use goroutines and channels for concurrency and to return errors directly from functions. Consider refactoring the method to align with Go best practices.

Use Enum Types in Filters for Enhanced Type Safety

⚠️ Potential issue

Implement Core Resolver Methods for Essential Functionality

The resolver methods for critical queries and mutations, such as ContractStateDiff, ContractState, FindTransaction, SubmitTransactionV1, and others, are currently unimplemented and contain panic statements. Implementing these methods is essential for the functionality of the GraphQL API.

Would you like assistance in generating stub implementations or outlining the logic for these resolver methods?

🛠️ Refactor suggestion

*Use Concrete Return Types Instead of 'string' for Witness-Related Resolvers

The resolver methods ActiveWitnessNodes, WitnessSchedule, NextWitnessSlot, and WitnessActiveScore return *string, which may not provide clear API contracts. Defining specific return types enhances type safety and clarity.

Separate Testing Methods from Production Code

The IncrementNumber method appears to be for testing purposes. It's advisable to move test-specific code to dedicated test files or packages to maintain a clean production codebase.

Separate Testing Methods from Production Code

The GetCurrentNumber method seems to be a test-related function. Consider relocating it to a test module to keep the production codebase clean and focused.
