🧹 Nitpick comments (16)
server/internal/app/main.go (3)
51-62: Consider a time-limited context for the Redis connection check.
While thePingcommand is useful to verify the Redis connection, it may hang indefinitely in certain network conditions. Wrapping it with a context that has a timeout can help avoid blocking the entire server startup.ctx := context.Background() +ctxTimeout, cancel := context.WithTimeout(ctx, 3*time.Second) +defer cancel() // ... _, err = redisClient.Ping(ctxTimeout).Result() if err != nil {
63-74: Gracefully handle Uptrace initialization failures.
Currently, the code does not check for errors fromuptrace.ConfigureOpentelemetryitself. While a fatal error is logged if the shutdown fails, consider logging or handling errors from the configuration as well, should it fail to initialize properly.
99-99: New field inServerConfigis consistent with the usage.
This field ensures the adapter is accessible whereverServerConfigis passed around. Consider documenting how it integrates with existing features for clarity.server/e2e/common.go (1)
85-98: Guard your tests against missing Redis.
Usingt.Fatalfis reasonable for test failures, but if Redis is optional, consider skipping tests when Redis is unavailable (e.g., running in short mode or partially offline). This helps avoid failing unrelated tests in environments without Redis.server/internal/usecase/interactor/style.go (4)
26-32: Constructor now receives a Redis gateway.
If the Redis gateway is not essential in some scenarios, consider documenting or handling a nil gateway scenario to avoid potential NPEs.
75-80: Failure in writing to cache after DB commit halts the operation entirely.
Currently, an error insetToCachestops the entire operation from succeeding. Consider whether failing to cache should block the operation or if you prefer a best-effort approach that allows the flow to complete, then logs the caching failure.
141-149: Similar comment on best-effort caching logic.
After a successful DB commit, consider whether caching failures should block the entire request.
Line range hint
215-244: Duplicated style caching.
Storing the duplicated style in the cache helps performance. Nothing critical here, but consider a unique or more descriptive cache key if duplication happens often, to avoid collisions or confusion if reading from cache logs.server/internal/usecase/gateway/redis.go (1)
5-9: Consider adding TTL parameter and value validation.The interface design looks good, but consider these improvements:
- Add TTL parameter to SetValue to prevent unbounded cache growth
- Consider adding type constraints or validation for the value parameter
- Add batch operations for better performance when handling multiple keys
Example enhancement:
type RedisGateway interface { GetValue(ctx context.Context, key string) (string, error) - SetValue(ctx context.Context, key string, value interface{}) error + SetValue(ctx context.Context, key string, value interface{}, ttl time.Duration) error RemoveValue(ctx context.Context, key string) error + // Batch operations + MGetValue(ctx context.Context, keys ...string) ([]string, error) + MSetValue(ctx context.Context, pairs map[string]interface{}, ttl time.Duration) error }server/e2e/ping_test.go (2)
13-20: Enhance Redis test coverage.While the miniredis setup is good, consider adding:
- Test cases for Redis connection failures
- Verification of Redis operations
- Test cleanup verification
Example test enhancement:
mr, err := miniredis.Run() if err != nil { t.Fatal(err) } defer mr.Close() + + // Test Redis operations + mr.Set("test_key", "test_value") + if got, err := mr.Get("test_key"); err != nil || got != "test_value" { + t.Errorf("Redis operation failed: got %v, err %v", got, err) + } + + // Test Redis connection failure + mr.Close() + e := StartServer(t, &config.Config{ + RedisURL: redisURL, + }, false, nil) + // Verify server handles Redis failure gracefully
19-19: Use environment variable for Redis URL.Consider using an environment variable for the Redis URL to match production configuration.
- redisURL := fmt.Sprintf("redis://:@%s/0", mr.Addr()) + redisURL := os.Getenv("TEST_REDIS_URL") + if redisURL == "" { + redisURL = fmt.Sprintf("redis://:@%s/0", mr.Addr()) + }server/pkg/scene/style.go (1)
59-61: Enhance cache key generation with validation and namespace.The cache key generation should:
- Validate the StyleID
- Include a namespace prefix for better organization
- Consider potential key collisions
func StyleCacheKey(id StyleID) string { - return fmt.Sprintf("style:%s", id) + if id.IsNil() { + return "" + } + return fmt.Sprintf("reearth:style:%s", id) }server/internal/adapter/gql/resolver_mutation_style.go (1)
33-36: Enhance OpenTelemetry tracing with error handling and attributes.The tracing implementation should include error recording and relevant attributes for better observability.
tracer := otel.Tracer("gql") ctx, span := tracer.Start(ctx, "mutationResolver.UpdateStyle") -defer span.End() +defer func() { + if err != nil { + span.RecordError(err) + span.SetStatus(codes.Error, err.Error()) + } + span.End() +}() +span.SetAttributes( + attribute.String("style.id", input.StyleID), + attribute.Bool("has_name", input.Name != nil), + attribute.Bool("has_value", input.Value != nil), +)server/internal/app/config/config.go (1)
77-77: Add documentation for UptraceDSN configuration.The UptraceDSN field lacks documentation about its format and usage. Consider adding comments to explain:
- Expected DSN format
- Configuration requirements
- Impact on tracing functionality
+ // UptraceDSN is the DSN for Uptrace observability platform. + // Format: https://uptrace.dev/get/connect.html#connection-url UptraceDSN string `envconfig:"UPTRACE_DSN" pp:",omitempty"`server/internal/usecase/interactor/common.go (2)
256-279: Consider adding cache TTL parameterWhile the implementation is solid, consider adding a TTL parameter to prevent cache entries from living indefinitely.
-func getFromCache[T any](ctx context.Context, redisClient any, cacheKey string) (T, error) { +func getFromCache[T any](ctx context.Context, redisClient any, cacheKey string, ttl time.Duration) (T, error) {
281-293: Add context timeout for Redis operationsConsider adding a timeout to the context for Redis operations to prevent hanging in case of Redis connectivity issues.
func setToCache[T any](ctx context.Context, redisClient any, cacheKey string, data T) error { + ctx, cancel := context.WithTimeout(ctx, 5*time.Second) + defer cancel() redisAdapter, ok := checkRedisClient(redisClient)

server/internal/app/main.go (2)
10-13: Imports look organized and purposeful.
You are bringing in Redis and Uptrace dependencies, which appear necessary for the new caching and observability features.Also applies to: 19-19
83-83: Excellent addition of the Redis adapter to the server.
AddingRedisAdaptertoNewServerhelps ensure that your Redis caching capability is available within the server lifecycle.server/e2e/common.go (2)
10-16: New imports for Redis in E2E tests are appropriate.
Ensuring the E2E tests can initialize Redis is vital for testing cache-related logic.
106-106: Redis adapter injected intoServerConfigfor E2E testing.
This seamlessly allows end-to-end tests to exercise real caching paths with Redis.server/internal/usecase/interactor/style.go (5)
7-14: New imports for gateway and OpenTelemetry tracing.
Integrating a caching gateway and tracing is a beneficial addition for observability and performance.
23-23: Addedredis gateway.RedisGatewayfield toStyle.
This new field cleanly extends the struct to incorporate caching mechanisms alongside the existing repository logic.
85-99: Tracing approach is well-structured but consider aggregator usage.
In the event multiple steps fail, be mindful of how the aggregator logs these spans for better user understanding. Overall, you’re capturing the necessary context in each trace.
113-126: Cache miss gracefully handled by fallback to DB.
This approach is a standard pattern for heavy read scenarios. The code looks consistent and follows the same pattern in other methods.
Line range hint
166-198: Delete from cache after successful repository removal.
This ordering ensures that the repository and cache remain in sync. Make sure to handle any errors from Redis gracefully to avoid partial deletes blocking the entire operation.server/pkg/scene/style.go (1)
6-9: Consider the implications of exposing internal fields.Making the fields public with msgpack tags suggests these are being exposed for serialization. While this enables Redis caching, it also increases the risk of external manipulation. Consider using an interface or implementing custom serialization methods to maintain encapsulation.
server/internal/app/usecase.go (1)
16-17: 🛠️ Refactor suggestionAdd Redis connection error handling.
The middleware should handle potential Redis connection failures gracefully. Consider:
- Adding error handling for Redis operations
- Implementing connection health checks
- Adding fallback behavior when Redis is unavailable
func UsecaseMiddleware(r *repo.Container, g *gateway.Container, ar *accountrepo.Container, ag *accountgateway.Container, redisAdapter *infraRedis.RedisAdapter, config interactor.ContainerConfig) echo.MiddlewareFunc { + if redisAdapter != nil { + if err := redisAdapter.Ping(); err != nil { + log.Warn("Redis connection failed, falling back to repository: %v", err) + redisAdapter = nil + } + } return ContextMiddleware(func(ctx context.Context) context.Context {Also applies to: 40-42
server/internal/app/app.go (1)
Line range hint
98-102: LGTM: Clean Redis adapter integrationThe Redis adapter is properly injected into the UsecaseMiddleware, following good dependency injection practices.
server/e2e/gql_style_test.go (2)
179-189: LGTM: Well-structured Redis test setupGood use of miniredis for testing Redis functionality. The setup is clean and handles cleanup properly with
defer mr.Close().
266-272: LGTM: Good test coverage strategyExcellent approach to test both with and without Redis using parameterized tests, ensuring the functionality works in both scenarios.
server/internal/usecase/interactor/common.go (1)
244-254: LGTM: Robust Redis client validationThe function properly handles nil checks and type assertions for the Redis client.
server/Makefile (1)
19-21: LGTM: Clean Makefile additionThe run-redis target follows the same pattern as run-db and is properly marked as .PHONY.
Also applies to: 25-25
server/go.mod (2)
39-39: Verify Uptrace and OpenTelemetry compatibility.Ensure that the Uptrace version (v1.24.0) is compatible with the OpenTelemetry SDK version (v1.24.0).
Also applies to: 47-48
✅ Verification successful
✓ Uptrace v1.24.0 is compatible with OpenTelemetry v1.24.0
The versions are perfectly aligned - Uptrace v1.24.0 is built against and compatible with OpenTelemetry v1.24.0 across all components (core, SDK, metrics, and tracing).

21-23: 🛠️ Refactor suggestionAdd TTL support and key validation.
The
SetValuemethod needs the following improvements:
- TTL support for cache expiration
- Key validation to prevent empty keys
Apply this diff to enhance the method:

🧹 Nitpick comments (8)
server/internal/usecase/interactor/common.go (4)
8-9: Replace direct redis import with an alias or single standard reference.Both lines introduce Redis into the codebase. While functional, consider standardizing the import references (either alias all imports or avoid renaming unless needed) to reduce cognitive load.
47-47: Check Style interactor for fallback logic.
NewStyle(r, redisAdapter)passes the Redis adapter. Verify thatNewStylegracefully handles scenarios where the adapter may be unavailable, preventing caching-related exceptions.
256-279: Consider logging when cache is unavailable.Currently,
getFromCachesilently returns a zero value ifredisClientis invalid or if a cache miss occurs. Consider logging or at least documenting this fallback behavior to help with debugging.
295-302: Align deleteFromCache with error handling strategy.Like
getFromCacheandsetToCache,deleteFromCacheignores cases whereredisClientis invalid. Consider adding optional logging or returning an informative error if the cache is disabled or unavailable.server/internal/infrastructure/redis/redis_adapter.go (2)
17-19: Add key validation and error wrapping.The
GetValuemethod should validate the key and wrap Redis errors for better error handling.Apply this diff to enhance the method:
func (r *RedisAdapter) GetValue(ctx context.Context, key string) (string, error) { + if key == "" { + return "", errors.New("key cannot be empty") + } - return r.client.Get(ctx, key).Result() + result, err := r.client.Get(ctx, key).Result() + if err != nil { + return "", fmt.Errorf("redis get failed: %w", err) + } + return result, nil }
25-27: Add key validation and error wrapping.The
RemoveValuemethod should validate the key and wrap Redis errors for better error handling.Apply this diff to enhance the method:
func (r *RedisAdapter) RemoveValue(ctx context.Context, key string) error { + if key == "" { + return errors.New("key cannot be empty") + } - return r.client.Del(ctx, key).Err() + if err := r.client.Del(ctx, key).Err(); err != nil { + return fmt.Errorf("redis delete failed: %w", err) + } + return nil }server/internal/app/main.go (1)
63-73: Validate Uptrace DSN before configuration.The Uptrace configuration should validate the DSN to prevent initialization with an empty or invalid DSN.
Add validation before configuring Uptrace:
// Init uptrace + if conf.UptraceDSN == "" { + log.Warn("Uptrace DSN is empty, skipping Uptrace initialization") + return + } uptrace.ConfigureOpentelemetry(server/e2e/gql_style_test.go (1)
179-188: Ensure Redis cleanup in test failure scenarios.The Redis cleanup is handled by
defer mr.Close(), but it's important to ensure cleanup happens even if the test fails before reaching the defer statement.Move the Redis initialization to a separate function:
+func initRedis(t *testing.T) (string, func()) { + mr, err := miniredis.Run() + if err != nil { + t.Fatal(err) + } + return fmt.Sprintf("redis://:@%s/0", mr.Addr()), func() { + mr.Close() + } +} func styleCRUD(t *testing.T, isUseRedis bool) { redisURL := "" + var cleanup func() if isUseRedis { - mr, err := miniredis.Run() - if err != nil { - t.Fatal(err) - } - defer mr.Close() - redisURL = fmt.Sprintf("redis://:@%s/0", mr.Addr()) + redisURL, cleanup = initRedis(t) + t.Cleanup(cleanup) }

51-66: LGTM! Robust Redis initialization.The Redis client initialization is well-implemented with proper error handling, connection testing, and cleanup.
88-88: LGTM! Clean struct field addition.The RedisAdapter field is properly integrated into the ServerConfig struct.
Also applies to: 104-104
server/internal/usecase/interactor/style.go (3)
27-27: LGTM! Clean Redis gateway integration.The Redis gateway is properly integrated into the Style struct and constructor.
Also applies to: 30-39
158-164:⚠️ Potential issueHandle cache set failure gracefully.
Cache set failures should not prevent returning a successful database update.
err = setToCache[*scene.Style](ctx, i.redis, scene.StyleCacheKey(style.ID()), style) if err != nil { dbSpan.RecordError(err) dbSpan.End() - return nil, err + log.Errorf("Cache set failed: %v", err) }Likely invalid or redundant comment.
116-121:⚠️ Potential issueHandle cache miss gracefully.
Cache retrieval errors should not be treated as critical failures. Consider logging the error and proceeding with the database lookup.
style, err = getFromCache[*scene.Style](ctx, i.redis, scene.StyleCacheKey(param.StyleID)) if err != nil { redisSpan.RecordError(err) redisSpan.End() - return nil, err + log.Errorf("Cache retrieval failed: %v", err) }Likely invalid or redundant comment.

🛠️ Refactor suggestion
Use the provided version parameter instead of hardcoding.
The service version is hardcoded as "1.0.0". Since the version is already available as a parameter to the Start function, use it instead.
uptrace.ConfigureOpentelemetry(
uptrace.WithDSN(conf.UptraceDSN),
uptrace.WithServiceName("reearth"),
- uptrace.WithServiceVersion("1.0.0"),
+ uptrace.WithServiceVersion(version),
)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
