PR Reviewer Guide 🔍

⏱️ Estimated effort to review: 5 🔵🔵🔵🔵🔵

🧪 PR contains tests

🔒 Security concerns Sensitive information exposure: The implementation of remote WebSocket connections and authorization flows introduces potential security risks. Special attention should be given to the handling of authentication tokens, secure communication channels, and protection against man-in-the-middle attacks. The RemoteWebSocketServerScenario and SolanaMobileWalletAdapterWallet classes should be carefully audited for any potential vulnerabilities in their handling of sensitive data and network communications.

⚡ Key issues to review Potential Security Issue The RemoteWebSocketServerScenario class handles sensitive operations like authorization and connection management. A thorough security review is needed to ensure proper handling of authentication tokens, secure WebSocket connections, and protection against potential vulnerabilities. Complex Implementation The SolanaMobileWalletAdapterWallet class is a large and complex implementation with multiple responsibilities. It may benefit from further modularization and separation of concerns to improve maintainability and testability. Test Coverage The new remote authorization test case (authorizationFlow_SuccessfulRemoteAuthorization) should be thoroughly reviewed to ensure it adequately covers all aspects of the remote authorization flow, including error cases and edge scenarios.

Category	Suggestion	Score
Best practice	Implement a more graceful shutdown process for the ScheduledExecutorService Consider implementing a more graceful shutdown process for the ScheduledExecutorService in the close() method. The current implementation might lead to tasks being abruptly terminated. android/walletlib/src/main/java/com/solana/mobilewalletadapter/walletlib/scenario/RemoteWebSocketServerScenario.java [245-251] private void destroyResourcesOnClose() { mReflectorWebSocket = null; if (mConnectionBackoffExecutor != null) { - mConnectionBackoffExecutor.shutdownNow(); + mConnectionBackoffExecutor.shutdown(); + try { + if (!mConnectionBackoffExecutor.awaitTermination(5, TimeUnit.SECONDS)) { + mConnectionBackoffExecutor.shutdownNow(); + } + } catch (InterruptedException e) { + mConnectionBackoffExecutor.shutdownNow(); + Thread.currentThread().interrupt(); + } mConnectionBackoffExecutor = null; } } Apply this suggestion Suggestion importance[1-10]: 9 Why: Implementing a more graceful shutdown process for the ScheduledExecutorService is a best practice that prevents abrupt task termination, enhancing application stability.	9
	Use a more appropriate exception type for better error handling and clarity Consider using a more specific exception type instead of UnsupportedOperationException when handling URI syntax errors in the constructor. android/fakewallet/src/androidTest/java/com/solana/mobilewalletadapter/clientlib/scenario/RemoteAssociationScenario.java [98] -throw new UnsupportedOperationException("Failed assembling a WebSocket URI", e); +throw new IllegalArgumentException("Failed assembling a WebSocket URI", e); Apply this suggestion Suggestion importance[1-10]: 8 Why: Replacing UnsupportedOperationException with IllegalArgumentException provides a more accurate representation of the error, improving error handling and clarity.	8
Enhancement	Add a timeout mechanism to prevent indefinite waiting during transactions Consider adding a timeout mechanism to the transact method to prevent indefinite waiting in case of network issues or unresponsive wallet. js/packages/wallet-adapter-mobile/src/adapterRemote.ts [315-353] -private async transact<TReturn>(callback: (wallet: Web3RemoteMobileWallet) => TReturn): Promise<TReturn> { +private async transact<TReturn>(callback: (wallet: Web3RemoteMobileWallet) => TReturn, timeout = 30000): Promise<TReturn> { const walletUriBase = this._authorizationResult?.wallet_uri_base; const baseConfig = walletUriBase ? { baseUri: walletUriBase } : undefined; const remoteConfig = { ...baseConfig, remoteHostAuthority: this._hostAuthority }; const currentConnectionGeneration = this._connectionGeneration; const modal = new EmbeddedDialogModal('MWA QR'); if (this._wallet) { return callback(this._wallet); } try { + const timeoutPromise = new Promise<never>((_, reject) => + setTimeout(() => reject(new Error('Transaction timeout')), timeout) + ); const { associationUrl, result: promise } = await transactRemote(async (wallet) => { const result = await callback(wallet); modal.close(); return result; }, remoteConfig); modal.init(associationUrl.toString()); modal.open(); - return await promise; + return await Promise.race([promise, timeoutPromise]); } catch (e) { modal.close(); if (this._connectionGeneration !== currentConnectionGeneration) { await new Promise(() => {}); // Never resolve. } if ( e instanceof Error && e.name === 'SolanaMobileWalletAdapterError' && ( e as SolanaMobileWalletAdapterError< typeof SolanaMobileWalletAdapterErrorCode[keyof typeof SolanaMobileWalletAdapterErrorCode] > ).code === 'ERROR_WALLET_NOT_FOUND' ) { await this._onWalletNotFound(this); } throw e; } } Apply this suggestion Suggestion importance[1-10]: 9 Why: Adding a timeout mechanism is a significant improvement that prevents the application from hanging indefinitely due to network issues or an unresponsive wallet. This suggestion enhances the robustness and reliability of the code, making it a crucial improvement.	9
	Implement a retry mechanism with exponential backoff for remote transactions Consider implementing a retry mechanism with exponential backoff for the transact method to handle temporary network issues or server unavailability. js/packages/wallet-adapter-mobile/src/adapterRemote.ts [315-353] private async transact<TReturn>(callback: (wallet: Web3RemoteMobileWallet) => TReturn): Promise<TReturn> { const walletUriBase = this._authorizationResult?.wallet_uri_base; const baseConfig = walletUriBase ? { baseUri: walletUriBase } : undefined; const remoteConfig = { ...baseConfig, remoteHostAuthority: this._hostAuthority }; const currentConnectionGeneration = this._connectionGeneration; const modal = new EmbeddedDialogModal('MWA QR'); if (this._wallet) { return callback(this._wallet); } - try { - const { associationUrl, result: promise } = await transactRemote(async (wallet) => { - const result = await callback(wallet); + const maxRetries = 3; + let retries = 0; + while (retries < maxRetries) { + try { + const { associationUrl, result: promise } = await transactRemote(async (wallet) => { + const result = await callback(wallet); + modal.close(); + return result; + }, remoteConfig); + modal.init(associationUrl.toString()); + modal.open(); + return await promise; + } catch (e) { modal.close(); - return result; - }, remoteConfig); - modal.init(associationUrl.toString()); - modal.open(); - return await promise; - } catch (e) { - modal.close(); - if (this._connectionGeneration !== currentConnectionGeneration) { - await new Promise(() => {}); // Never resolve. + if (this._connectionGeneration !== currentConnectionGeneration) { + await new Promise(() => {}); // Never resolve. + } + if ( + e instanceof Error && + e.name === 'SolanaMobileWalletAdapterError' && + ( + e as SolanaMobileWalletAdapterError< + typeof SolanaMobileWalletAdapterErrorCode[keyof typeof SolanaMobileWalletAdapterErrorCode] + > + ).code === 'ERROR_WALLET_NOT_FOUND' + ) { + await this._onWalletNotFound(this); + throw e; + } + retries++; + if (retries >= maxRetries) { + throw e; + } + await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, retries))); } - if ( - e instanceof Error && - e.name === 'SolanaMobileWalletAdapterError' && - ( - e as SolanaMobileWalletAdapterError< - typeof SolanaMobileWalletAdapterErrorCode[keyof typeof SolanaMobileWalletAdapterErrorCode] - > - ).code === 'ERROR_WALLET_NOT_FOUND' - ) { - await this._onWalletNotFound(this); - } - throw e; } + throw new Error('Max retries exceeded'); } Apply this suggestion Suggestion importance[1-10]: 8 Why: Implementing a retry mechanism with exponential backoff is a valuable enhancement for handling transient network issues, improving the reliability of the transact method. This suggestion addresses potential network instability, which is crucial for maintaining a seamless user experience.	8
	Implement a more robust method for parsing the reflector ID from the URI query string Consider using a more robust method for parsing the reflector ID from the URI query string. The current regex pattern might be prone to errors if the query string format changes. android/walletlib/src/main/java/com/solana/mobilewalletadapter/walletlib/scenario/RemoteWebSocketServerScenario.java [51] -private final Pattern idPattern = Pattern.compile("id=([0-9]*)"); +private long parseReflectorId(URI uri) { + String query = uri.getQuery(); + if (query != null) { + for (String param : query.split("&")) { + String[] pair = param.split("="); + if (pair.length == 2 && "id".equals(pair[0])) { + try { + return Long.parseLong(pair[1]); + } catch (NumberFormatException e) { + Log.w(TAG, "Invalid reflector ID: " + pair[1]); + } + } + } + } + throw new IllegalArgumentException("Reflector ID not found in URI"); +} Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion to use a more robust method for parsing the reflector ID enhances reliability and reduces potential errors from format changes, making it a valuable improvement.	7
	Use a mock server for more robust remote reflector simulation in tests Consider using a more robust way to simulate the remote reflector server, such as using a mock server library or a real test server instance. This would provide a more realistic test environment and potentially uncover edge cases. android/fakewallet/src/androidTest/java/com/solana/mobilewalletadapter/fakewallet/MainActivityTest.kt [201-203] // simulate remote reflector server -val port = 8881 -val server = WebSocketReflectorServer(port) -server.init() +val mockServer = MockWebServer() +mockServer.start(8881) +mockServer.enqueue(MockResponse().withWebSocketUpgrade(WebSocketListener())) Apply this suggestion Suggestion importance[1-10]: 7 Why: Using a mock server for testing is a good practice as it can simulate more realistic network conditions and edge cases, improving the robustness of the tests. However, the existing code already provides a basic simulation, so this suggestion is an enhancement rather than a critical fix.	7
	Replace the hardcoded backoff schedule array with an enum for improved readability and maintainability Consider using an enum for the connection backoff schedule instead of a hardcoded array. This would improve readability and make it easier to modify the schedule in the future. android/walletlib/src/main/java/com/solana/mobilewalletadapter/walletlib/scenario/RemoteWebSocketServerScenario.java [36] -private static final int[] CONNECT_BACKOFF_SCHEDULE_MS = { 150, 150, 200, 500, 500, 750, 750, 1000 }; // == 30s, which allows time for a user to choose a wallet from the disambiguation dialog, and for that wallet to start +private enum ConnectBackoffSchedule { + ATTEMPT_1(150), ATTEMPT_2(150), ATTEMPT_3(200), ATTEMPT_4(500), + ATTEMPT_5(500), ATTEMPT_6(750), ATTEMPT_7(750), ATTEMPT_8(1000); + private final int delayMs; + + ConnectBackoffSchedule(int delayMs) { + this.delayMs = delayMs; + } + + public int getDelayMs() { + return delayMs; + } +} + Apply this suggestion Suggestion importance[1-10]: 5 Why: Using an enum for the connection backoff schedule can improve readability and maintainability, but it is not a critical change. The current array is straightforward and functional.	5
Possible issue	Use a thread-safe collection for managing half-open connections Consider using a concurrent collection like ConcurrentHashMap for mHalfOpenConnections to avoid potential race conditions when accessing this map from different threads. android/walletlib/src/main/java/com/solana/mobilewalletadapter/walletlib/scenario/RemoteWebSocketServerScenario.java [47] -private final Map<Long, ReflectorWebSocket> mHalfOpenConnections = new HashMap<>(); +private final Map<Long, ReflectorWebSocket> mHalfOpenConnections = new ConcurrentHashMap<>(); Apply this suggestion Suggestion importance[1-10]: 8 Why: Switching to a ConcurrentHashMap for mHalfOpenConnections addresses potential race conditions, improving thread safety and reliability in a concurrent environment.	8
Maintainability	Replace magic numbers with named constants for improved code readability Consider using a constant for the magic number 1 in the onSessionEstablished and onSessionClosed methods to improve code readability and maintainability. android/walletlib/src/main/java/com/solana/mobilewalletadapter/walletlib/scenario/LocalScenario.java [115] -if (mClientCount.incrementAndGet() == 1) { +private static final int FIRST_CLIENT = 1; +if (mClientCount.incrementAndGet() == FIRST_CLIENT) { + Apply this suggestion Suggestion importance[1-10]: 7 Why: Using a named constant instead of a magic number improves code readability and maintainability, making the code easier to understand and modify.	7
