(DAL) Framework Migration #2133
Conversation
WalkthroughWalkthroughThe updates introduce a new version of the Orakl Node Data Access Layer (DAL) API, enhancing its capabilities with a WebSocket server alongside a RESTful API. Key components, such as data handling and client subscription management, are reorganized for improved modularity and flexibility. This refactoring optimizes the overall architecture, ensuring efficient interaction between clients and data streams through enhanced error handling, configuration options, and testing. Changes

17-19: Consider renamingDBKeyResultfor clarity.While
DBKeyResultis functional, consider a more descriptive name likeAPIKeyExistenceResultto clearly convey its purpose.- type DBKeyResult struct { + type APIKeyExistenceResult struct {node/pkg/dal/hub/hub.go (5)
71-100: Validate subscription handling and error logging.The
HandleSubscriptionmethod processes client subscriptions. Ensure that invalid subscriptions are logged and handled appropriately. Consider logging the invalid parameters for better traceability.+ log.Info().Strs("invalid_params", invalidParams).Msg("invalid subscription parameters")
113-120: Improve client addition logic.In
addClient, the check and insertion of a client are performed under a lock. Consider logging when a client is successfully added for better traceability.+ log.Info().Msg("client added successfully")
122-137: Enhance error handling during client removal.In
removeClient, the error fromclient.Closeis logged as a warning. Consider logging additional context, such as the client identifier, to aid in debugging.+ log.Warn().Err(err).Str("client", client.RemoteAddr().String()).Msg("failed to write close message")
25-32: Ensure proper synchronization for concurrent accessThe
Hubstruct'sClientsandbroadcastfields should be accessed within lock/unlock blocks to prevent data races. TheremoveClientfunction correctly uses a lock, but other accesses toClientsandbroadcastare not shown to be synchronized. Please review the following locations:
- Accesses to
Clientsin functions without lock/unlock.- Accesses to
broadcastin functions without lock/unlock.Consider adding synchronization to these areas to ensure thread safety.
Analysis chain
Ensure proper synchronization for concurrent access.
The
Hubstruct uses async.RWMutexto manage concurrent access toClients. Ensure that all read and write operations onClientsandbroadcastare properly synchronized to avoid data races.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify that all accesses to `Clients` and `broadcast` in `Hub` are synchronized. # Test: Search for `Clients` and `broadcast` usage. Expect: All accesses are within lock/unlock blocks. rg --type go 'Clients|broadcast' -A 5Length of output: 6491
59-69: Improve Goroutine Management inhub.goThe
handleClientRegistrationandbroadcastDataForSymbolmethods inhub.godo not handle context cancellation, which could lead to goroutine leaks. Consider modifying these methods to listen forctx.Done()and terminate appropriately when the context is canceled.
handleClientRegistration: Add context cancellation handling.broadcastDataForSymbol: Add context cancellation handling.Analysis chain
Review goroutine management and potential leaks.
The
Startmethod launches several goroutines. Ensure that these goroutines are properly managed and do not lead to resource leaks, especially when theHubis stopped or the context is canceled.Scripts executed

ServeHTTPmethod checks the API key for requests. Ensure that the validation logic is robust and that unauthorized access is properly logged.+ log.Warn().Str("key", key).Msg("unauthorized access attempt")
116-155: Enhance error handling inWSHandler.The
WSHandlerfunction handles websocket connections. Ensure that all error cases are logged with sufficient detail, and consider adding retry logic for transient errors.+ log.Error().Err(err).Msg("websocket handler encountered an error")
157-160: Improve health check response.The
HealthCheckHandlerprovides a basic health check. Consider including additional information, such as version or uptime, in the response for better diagnostics.+ w.Write([]byte("Orakl Node DAL API - Version 1.0.0"))
173-178: Improve error handling inAllLatestFeedsHandler.The
AllLatestFeedsHandlerreturns the latest data feeds. Ensure that any errors in data retrieval are logged and handled appropriately.+ log.Error().Err(err).Msg("failed to retrieve latest data feeds")
196-242: Enhance error handling inTransposedLatestFeedsHandler.The
TransposedLatestFeedsHandlerprocesses symbol requests. Ensure that all error cases are logged with sufficient detail, and consider validating symbol formats more robustly.+ log.Error().Err(err).Str("symbol", symbol).Msg("failed to process symbol request")
244-284: Validate and log symbol errors inLatestFeedsHandler.The
LatestFeedsHandlerprocesses and returns data for symbols. Ensure that symbol format errors are logged with sufficient detail to aid in debugging.+ log.Error().Str("symbol", symbol).Msg("invalid symbol format")
68-85: Review the handler registration for HTTP methods.The
http.ServeMuxtypically does not support method-specific paths like "GET /symbols". To ensure correct functionality, verify that HTTP methods are handled appropriately, possibly by adding method checks within the handlers themselves.
- File:
node/pkg/dal/apiv2/controller.go- Lines: 68-85
Consider revising the handler registration to correctly handle HTTP methods.

104-115: Review data retrieval timing inTestApiGetLatestAll.The
TestApiGetLatestAllrelies on a sleep to wait for data publication. Consider using a more robust synchronization mechanism to ensure data readiness.// Consider using a wait group or channel to synchronize data readiness
132-139: Clarify test expectations inTestShouldFailWithoutApiKey.The
TestShouldFailWithoutApiKeychecks unauthorized access. Ensure that the test clearly documents the expected behavior and any assumptions.+ t.Log("Expecting 401 Unauthorized due to missing API key")
