network-client-core/src/main/java/io/ably/lib/network/EngineType.java (1)
1-6: LGTM! Consider adding documentation.The
EngineTypeenum is well-structured and follows Java naming conventions. It aligns with the PR objectives of decoupling HTTP and WebSocket engines.To improve maintainability and clarity, consider adding documentation:
/** * Represents the type of network engine used in the Ably client. */ public enum EngineType { /** The default network engine implementation. */ DEFAULT, /** The OkHttp-based network engine implementation. */ OKHTTP }network-client-core/src/main/java/io/ably/lib/network/ProxyAuthType.java (1)
1-6: LGTM! Consider adding Javadoc for better documentation.The introduction of the
ProxyAuthTypeenum is a good addition to the codebase. It provides a clear and type-safe way to represent proxy authentication types, which aligns well with the refactoring objectives of the PR.Consider adding Javadoc comments to the enum and its constants for better documentation. Here's a suggested improvement:
package io.ably.lib.network; +/** + * Represents the types of proxy authentication supported. + */ public enum ProxyAuthType { + /** Basic authentication for proxies. */ BASIC, + /** Digest authentication for proxies. */ DIGEST }This addition would provide more context for developers using this enum in the future.
network-client-core/src/main/java/io/ably/lib/network/HttpEngine.java (3)
4-4: LGTM: Well-designed method signature. Consider adding Javadoc.The
callmethod is well-structured with appropriate parameter and return types. It aligns with the PR objective of abstracting HTTP calls.Consider adding Javadoc to provide more details about the method's behavior, parameters, and return value. For example:
/** * Initiates an HTTP call with the given request. * * @param request The HTTP request to be executed. * @return An HttpCall object representing the executed call. */ HttpCall call(HttpRequest request);
5-5: LGTM: Clear and concise method for proxy usage check. Consider adding Javadoc.The
isUsingProxymethod is well-named and has an appropriate return type. It provides useful information about the network configuration.Consider adding Javadoc to clarify the method's behavior. For example:
/** * Checks if the HTTP engine is configured to use a proxy. * * @return true if a proxy is being used, false otherwise. */ boolean isUsingProxy();
1-6: Overall, excellent interface design. Consider adding a package-level comment.The
HttpEngineinterface is well-structured and aligns perfectly with the PR objectives of decoupling HTTP functionality and providing an abstraction layer. The methods are appropriately designed for their purposes.To further enhance the code, consider adding a package-level comment at the top of the file to provide an overview of the interface's role in the broader system. For example:
/** * This package contains core networking interfaces for the Ably Java library. * The HttpEngine interface defines the contract for HTTP request handling, * allowing for flexible implementations and easier testing. */ package io.ably.lib.network; // ... rest of the filenetwork-client-core/src/main/java/io/ably/lib/network/WebSocketEngine.java (1)
1-5: LGTM! Well-designed interface for WebSocket client creation.The
WebSocketEngineinterface is well-designed and aligns with the PR objectives. It provides a clean abstraction for creating WebSocket clients, which will facilitate easier swapping of implementations in the future.Consider adding Javadoc comments to improve documentation:
package io.ably.lib.network; +/** + * An interface for creating WebSocket clients. + */ public interface WebSocketEngine { + /** + * Creates a new WebSocket client. + * + * @param url The WebSocket server URL. + * @param listener A listener for WebSocket events. + * @return A new WebSocket client instance. + */ WebSocketClient create(String url, WebSocketListener listener); }network-client-core/src/main/java/io/ably/lib/network/NotConnectedException.java (1)
1-7: LGTM! Consider adding documentation and a custom message.The
NotConnectedExceptionclass is well-structured and follows Java conventions. It correctly extendsRuntimeExceptionand provides a constructor for exception chaining.Consider the following improvements:
- Add JavaDoc to the class and constructor for better documentation.
- Include a custom message in the exception for more informative error reporting.
Here's a suggested implementation with these improvements:
package io.ably.lib.network; /** * Exception thrown when a network operation is attempted but no connection is available. */ public class NotConnectedException extends RuntimeException { private static final String DEFAULT_MESSAGE = "Operation failed due to lack of network connection"; /** * Constructs a new NotConnectedException with the specified cause and a default message. * * @param cause the cause (which is saved for later retrieval by the {@link #getCause()} method) */ public NotConnectedException(Throwable cause) { super(DEFAULT_MESSAGE, cause); } }This version includes JavaDoc and a default message, making the exception more self-explanatory and easier to use.
network-client-core/src/main/java/io/ably/lib/network/HttpConnectionException.java (1)
1-7: LGTM! Consider enhancing with JavaDoc and additional information.The
HttpConnectionExceptionclass is well-structured and follows good practices for custom exceptions. It properly extendsRuntimeExceptionand provides a constructor for exception chaining.Consider the following enhancements:
- Add JavaDoc to the class and constructor for better documentation:
/** * Exception thrown when an HTTP connection error occurs. */ public class HttpConnectionException extends RuntimeException { /** * Constructs a new HttpConnectionException with the specified cause. * * @param cause the cause of this exception */ public HttpConnectionException(Throwable cause) { super(cause); } }
- Consider adding more specific information or methods to provide details about the HTTP connection error. For example:
public class HttpConnectionException extends RuntimeException { private final int statusCode; public HttpConnectionException(Throwable cause, int statusCode) { super(cause); this.statusCode = statusCode; } public int getStatusCode() { return statusCode; } }These additions would make the exception more informative and useful for error handling and debugging.
network-client-core/build.gradle.kts (1)
6-9: Consider upgrading Java version in the future.The configuration for Java 1.8 compatibility is correct and ensures broad compatibility. However, Java 8 is quite old now. While this configuration is acceptable, it might be beneficial to consider upgrading to a newer Java version in the future for improved performance and access to newer language features.
network-client-okhttp/src/main/java/io/ably/lib/network/OkHttpEngine.java (1)
1-14: Consider additional components for a complete implementation.While the basic structure of the
OkHttpEngineclass is in place, there are several components that might be needed for a complete and efficient implementation:
- Add a private
OkHttpClientfield, which can be reused for multiple requests.- Implement a constructor that initializes the
OkHttpClientwith any necessary configurations.- Add methods to handle different types of HTTP requests (GET, POST, PUT, DELETE, etc.).
- Implement error handling and exception translation to maintain consistency with the
HttpEngineinterface.- Consider adding logging for debugging purposes.
- Implement any necessary cleanup methods (e.g., to close connections when the engine is no longer needed).
Here's a skeleton of what the complete class might look like:
import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.Response; import java.io.IOException; public class OkHttpEngine implements HttpEngine { private final OkHttpClient client; public OkHttpEngine() { this.client = new OkHttpClient.Builder() // Add any necessary configurations .build(); } @Override public HttpCall call(HttpRequest request) { Request okHttpRequest = buildOkHttpRequest(request); return new OkHttpCall(client.newCall(okHttpRequest)); } @Override public boolean isUsingProxy() { return client.proxy() != null; } private Request buildOkHttpRequest(HttpRequest request) { // Convert HttpRequest to OkHttp's Request // ... } // Additional methods as needed }This structure provides a more complete foundation for the
OkHttpEngineclass.build.gradle (1)
5-5: LGTM! Consider checking for the latest stable version.The addition of the Lombok plugin (io.freefair.lombok) is a good choice for reducing boilerplate code and aligns well with the PR's refactoring objectives. The 'apply false' directive allows for selective application to subprojects, which is a flexible approach.
While version 5.0.1 is specified, it's worth verifying if this is the latest stable version of the Lombok plugin. You might want to check https://plugins.gradle.org/plugin/io.freefair.lombok for the most recent version to ensure you're getting the latest features and bug fixes.
network-client-core/src/main/java/io/ably/lib/network/HttpBody.java (1)
12-13: LGTM: Appropriate field declarations with a suggestion for null safetyThe fields
contentType(String) andcontent(byte[]) are well-chosen to represent an HTTP body. The use offinalensures immutability, which is a good practice for thread safety and preventing unintended modifications.Consider adding null checks in the constructor or using
@NonNullannotations to ensure null safety, especially for thecontentfield. This can prevent potentialNullPointerExceptions when working with the HTTP body data.Example implementation:
@NonNull private final String contentType; @NonNull private final byte[] content; public HttpBody(@NonNull String contentType, @NonNull byte[] content) { this.contentType = contentType; this.content = content.clone(); // Defensive copy for immutability }network-client-core/src/main/java/io/ably/lib/network/HttpEngineConfig.java (1)
13-15: Consider future extensibility of HttpEngineConfig.The class structure is clean and supports immutability, which is good. The single
proxyfield of typeProxyConfigis appropriate for the current requirements.However, consider the potential need for additional HTTP engine configuration options in the future. While it's generally good to start with a minimal design, it might be worth discussing if there are any foreseeable additional configuration options that could be included now to avoid future breaking changes.
network-client-default/src/main/java/io/ably/lib/network/DefaultHttpEngineFactory.java (1)
10-13: LGTM: Engine type getter is implemented correctly.The
getEngineTypemethod is correctly implemented:
- It returns the appropriate engine type (
EngineType.DEFAULT).- The method name clearly describes its purpose.
Consider making
EngineType.DEFAULTa private static final field of the class for better maintainability:public class DefaultHttpEngineFactory implements HttpEngineFactory { + private static final EngineType ENGINE_TYPE = EngineType.DEFAULT; // ... other methods ... @Override public EngineType getEngineType() { - return EngineType.DEFAULT; + return ENGINE_TYPE; } }This change would centralize the engine type definition, making it easier to update if needed in the future.
network-client-default/src/main/java/io/ably/lib/network/DefaultWebSocketEngineFactory.java (1)
1-14: Consider adding class-level documentation.The implementation looks good and aligns well with the Factory pattern and PR objectives. To further enhance maintainability, consider adding class-level documentation (JavaDoc) to explain the purpose of this factory and its role in the WebSocket engine abstraction.
Here's a suggested JavaDoc comment to add above the class declaration:
/** * A factory for creating default WebSocket engine instances. * This class is part of the WebSocket engine abstraction layer, * allowing for easy swapping of WebSocket implementations. */ public class DefaultWebSocketEngineFactory implements WebSocketEngineFactory { // ... existing code ... }network-client-core/src/main/java/io/ably/lib/network/WebSocketListener.java (1)
6-12: LGTM with suggestions: Methods cover essential WebSocket events.The interface methods effectively cover the main WebSocket events and some specific scenarios. However, consider the following suggestions for improvement:
- Consider adding an
onPong()method to complementonWebsocketPing().- The
onOldJavaVersionDetectedmethod seems very specific. Consider if this belongs in a more general error handling method or a separate interface for version-specific concerns.- For consistency, consider renaming
onWebsocketPing()toonPing()to match the style of other method names.network-client-core/src/main/java/io/ably/lib/network/HttpResponse.java (1)
12-15: LGTM: Class annotations create an immutable DTO with builder pattern.The combination of Lombok annotations (@DaTa, @Setter(AccessLevel.NONE), @builder, @AllArgsConstructor) effectively creates an immutable class with a builder pattern, which is excellent for DTOs. This approach reduces boilerplate code and ensures thread-safety.
Consider adding
@EqualsAndHashCode(callSuper = false)to explicitly define equality based on the fields of this class only, in case this class is extended in the future.network-client-core/src/main/java/io/ably/lib/network/WebSocketEngineConfig.java (3)
11-15: LGTM: Well-chosen Lombok annotations for an immutable configuration class.The annotations create an immutable, easy-to-use configuration class:
@Dataprovides getters, toString, equals, and hashCode methods.@Setter(AccessLevel.NONE)prevents setter generation, ensuring immutability.@Builderallows for a fluent API for object creation.@AllArgsConstructorgenerates a constructor with all fields as parameters.Consider adding
@Getterexplicitly for clarity, even though it's included in@Data:@Data @Setter(AccessLevel.NONE) +@Getter @Builder @AllArgsConstructor public class WebSocketEngineConfig {
16-19: LGTM: Well-defined immutable fields for WebSocket configuration.The fields cover essential aspects of WebSocket configuration and are correctly declared as private and final, ensuring immutability.
Consider adding Javadoc comments for each field to improve documentation:
public class WebSocketEngineConfig { + /** The proxy configuration for the WebSocket connection. */ private final ProxyConfig proxy; + /** Indicates whether TLS should be used for the connection. */ private final boolean tls; + /** The host address for the WebSocket connection. */ private final String host; + /** The SSL socket factory for secure connections. */ private final SSLSocketFactory sslSocketFactory; }
1-20: Excellent implementation of WebSocketEngineConfig class.This new class aligns well with the PR objective of decoupling HTTP and WebSocket engines. Key points:
- The use of Lombok annotations reduces boilerplate while maintaining clarity.
- The class is immutable, which is ideal for configuration objects.
- The builder pattern (via
@Builder) will facilitate easy creation and modification of configurations.- The fields cover essential aspects of WebSocket configuration.
This implementation provides a solid foundation for managing WebSocket configurations in a decoupled manner, enhancing the flexibility and maintainability of the codebase.
To further improve the abstraction:
- Consider creating an interface
WebSocketConfigthat this class implements. This would allow for easier swapping of different WebSocket configuration implementations in the future if needed.- You might want to add a
validate()method to ensure all required fields are set correctly before the configuration is used.network-client-core/src/main/java/io/ably/lib/network/ProxyConfig.java (2)
11-14: LGTM: Effective use of Lombok annotations for an immutable configuration object.The combination of
@Data,@Setter(AccessLevel.NONE),@Builder, and@AllArgsConstructorcreates an immutable configuration object with a builder pattern. This is a good practice for configuration classes.Consider adding
@Getterexplicitly for clarity, even though it's included in@Data. This makes the intent more obvious:@Data @Setter(AccessLevel.NONE) +@Getter @Builder @AllArgsConstructor public class ProxyConfig {
15-22: LGTM: Well-structured proxy configuration class with comprehensive fields.The
ProxyConfigclass is well-designed with fields covering all essential proxy configuration parameters. The use ofList<String>fornonProxyHostsand a separateProxyAuthTypeforauthTypedemonstrates good design choices.Consider adding validation for the
portfield to ensure it's within the valid range (0-65535). You can achieve this by using Lombok's@Builder.Defaultwith a custom setter method:@Data @Setter(AccessLevel.NONE) @Builder @AllArgsConstructor public class ProxyConfig { private String host; - private int port; + @Builder.Default + private int port = -1; private String username; private String password; private List<String> nonProxyHosts; private ProxyAuthType authType; + + private void setPort(int port) { + if (port < 0 || port > 65535) { + throw new IllegalArgumentException("Port must be between 0 and 65535"); + } + this.port = port; + } }This change ensures that the
portis always valid when set, while still allowing it to be unspecified (indicated by -1) if not provided during construction.network-client-default/src/main/java/io/ably/lib/network/DefaultWebSocketEngine.java (1)
12-19: LGTM: Well-implementedcreatemethod with a minor improvement suggestion.The
createmethod is well-implemented, correctly using the configuration to set up theDefaultWebSocketClient. The conditional TLS setup is a good security practice. Returning the interface typeWebSocketClientrather than the concrete implementation is excellent for maintaining abstraction.Consider adding null checks and validation for the input parameters
urlandlistenerto improve robustness. For example:@Override public WebSocketClient create(String url, WebSocketListener listener) { if (url == null || url.isEmpty()) { throw new IllegalArgumentException("URL cannot be null or empty"); } if (listener == null) { throw new IllegalArgumentException("WebSocketListener cannot be null"); } DefaultWebSocketClient client = new DefaultWebSocketClient(URI.create(url), listener, config); if (config.isTls()) { client.setSocketFactory(config.getSslSocketFactory()); } return client; }network-client-default/src/main/java/io/ably/lib/network/DefaultHttpEngine.java (3)
10-12: LGTM: Constructor is simple and correct.The constructor correctly initializes the
configfield with the providedHttpEngineConfigobject.Consider adding null-check validation for the
configparameter to prevent potentialNullPointerExceptions:public DefaultHttpEngine(HttpEngineConfig config) { + if (config == null) { + throw new IllegalArgumentException("HttpEngineConfig cannot be null"); + } this.config = config; }
14-20: LGTM:callmethod implements proxy logic correctly.The method effectively creates a
Proxyobject based on the configuration and returns a newDefaultHttpCallwith the appropriate parameters.Consider adding error handling for potential
IllegalArgumentExceptionwhen creatingInetSocketAddress:@Override public HttpCall call(HttpRequest request) { - Proxy proxy = isUsingProxy() - ? new Proxy(Proxy.Type.HTTP, new InetSocketAddress(config.getProxy().getHost(), config.getProxy().getPort())) - : Proxy.NO_PROXY; - return new DefaultHttpCall(request, proxy); + Proxy proxy = Proxy.NO_PROXY; + if (isUsingProxy()) { + try { + proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(config.getProxy().getHost(), config.getProxy().getPort())); + } catch (IllegalArgumentException e) { + // Log the error and fall back to NO_PROXY + System.err.println("Invalid proxy configuration: " + e.getMessage()); + } + } + return new DefaultHttpCall(request, proxy); }This change improves error handling and provides a fallback mechanism in case of invalid proxy configuration.
22-25: LGTM:isUsingProxymethod is simple and correct.The method correctly determines if a proxy is being used based on the
config.getProxy()value.For added robustness, consider adding a null check for
config:@Override public boolean isUsingProxy() { - return config.getProxy() != null; + return config != null && config.getProxy() != null; }This change would prevent a
NullPointerExceptionifconfigis null, which could happen if the constructor is modified in the future to allow null values.dependencies.gradle (1)

network-client-core/src/main/java/io/ably/lib/network/WebSocketClient.java (6)
5-5: Consider adding documentation for theconnect()method.While the method name is self-explanatory, it would be beneficial to add a Javadoc comment describing its purpose, any potential exceptions it might throw, and any important details about the connection process.
Here's a suggested Javadoc comment:
/** * Initiates a WebSocket connection. * * @throws IOException if an I/O error occurs while creating the connection * @throws WebSocketException if the connection cannot be established */ void connect();
12-18: LGTM! Well-documented method with a minor suggestion.The
close(int code, String reason)method is well-documented with clear explanations for its parameters.Consider adding
@throwstags if this method can throw any exceptions, and possibly an@seetag referencing related methods or specifications (e.g., WebSocket protocol RFC). Here's a suggested addition:* @throws IllegalArgumentException if the code is not valid per WebSocket protocol * @see <a href="https://tools.ietf.org/html/rfc6455#section-7.4">RFC 6455, Section 7.4: Status Codes</a>
20-27: LGTM! Well-documented method with a minor formatting suggestion.The
cancel(int code, String reason)method is well-documented, clearly explaining its purpose and how it differs from theclosemethods.Consider formatting the comment as proper Javadoc by adding
@paramtags for each parameter and possibly@throwsif any exceptions can be thrown. Here's a suggested revision:/** * This will close the connection immediately without a proper close handshake. The code and the * message therefore won't be transferred over the wire also they will be forwarded to `onClose`. * * @param code the closing code * @param reason the closing message * @throws IllegalArgumentException if the code is not valid per WebSocket protocol */ void cancel(int code, String reason);
29-29: Consider adding documentation for thesend(byte[] message)method.While the method name is clear, it would be beneficial to add a Javadoc comment describing its purpose, any potential exceptions it might throw, and any important details about the message sending process.
Here's a suggested Javadoc comment:
/** * Sends a binary message over the WebSocket connection. * * @param message the byte array containing the message to be sent * @throws IOException if an I/O error occurs while sending the message * @throws IllegalStateException if the connection is not open */ void send(byte[] message);
31-31: Consider adding documentation for thesend(String message)method.While the method name is clear, it would be beneficial to add a Javadoc comment describing its purpose, any potential exceptions it might throw, and its relationship to the
send(byte[] message)method.Here's a suggested Javadoc comment:
/** * Sends a text message over the WebSocket connection. * * @param message the String message to be sent * @throws IOException if an I/O error occurs while sending the message * @throws IllegalStateException if the connection is not open * @see #send(byte[]) */ void send(String message);
1-33: Consider expanding the interface to handle incoming messages and connection state.The
WebSocketClientinterface provides a good foundation for WebSocket operations. However, to make it more complete and easier to use, consider adding the following methods:
A method to handle incoming messages:
void onMessage(MessageHandler handler);Methods to handle connection state changes:
void onOpen(ConnectionHandler handler); void onClose(CloseHandler handler); void onError(ErrorHandler handler);A method to check the current connection state:
ConnectionState getState();These additions would make the interface more robust and allow for better control and monitoring of the WebSocket connection.
network-client-core/src/main/java/io/ably/lib/network/HttpRequest.java (2)
14-27: LGTM: Well-designed immutable HttpRequest class.The use of Lombok annotations (@DaTa, @Setter(AccessLevel.NONE), @AllArgsConstructor) effectively reduces boilerplate code while promoting immutability. The fields cover all necessary components of an HTTP request, and the class is designed to be immutable, which is good for thread-safety.
Consider adding
@Builderannotation to the class to automatically generate a builder pattern. This would eliminate the need for a customHttpRequestBuilderclass. Example:@Data @Setter(AccessLevel.NONE) @AllArgsConstructor @Builder public class HttpRequest { // ... existing fields ... }This change would simplify the code and maintain the same functionality.
29-78: LGTM: Well-implemented Builder pattern.The
HttpRequestBuilderclass effectively implements the Builder pattern, providing a fluent interface for constructingHttpRequestinstances. The conversion of headers fromMap<String, String>toMap<String, List<String>>in theheadersmethod ensures compatibility with HTTP standards.Consider adding validation checks in the
buildmethod to ensure all required fields are set before creating theHttpRequestinstance. For example:public HttpRequest build() { Objects.requireNonNull(url, "URL must not be null"); Objects.requireNonNull(method, "HTTP method must not be null"); if (httpOpenTimeout <= 0) { throw new IllegalStateException("HTTP open timeout must be positive"); } if (httpReadTimeout <= 0) { throw new IllegalStateException("HTTP read timeout must be positive"); } return new HttpRequest(this.url, this.method, this.httpOpenTimeout, this.httpReadTimeout, this.body, this.headers); }This would prevent the creation of invalid
HttpRequestinstances.lib/src/main/java/io/ably/lib/http/HttpScheduler.java (1)
Line range hint
1-479: Summary: Good progress on refactoring, but consider further improvementsThe changes in this file represent a positive step towards decoupling HTTP and WebSocket engines by introducing the
HttpCallabstraction. However, to fully achieve the PR objectives, consider the following suggestions:
- Extend the use of
HttpCallthroughout the class for consistency.- Review and update the
HttpCoreclass to work seamlessly withHttpCall.- Ensure that all HTTP-related operations in this file are using the new abstraction.
These improvements will help to fully realize the benefits of the decoupling effort and make the code more maintainable and flexible for future changes.

990-1004: Consider adding error handling for null HttpRequestWhile the changes improve the abstraction, it's important to ensure robust error handling. Consider adding a null check for the
HttpRequestparameter at the beginning of theonRawHttpRequestmethod.Here's a suggested improvement:
public HttpCore.Response onRawHttpRequest(String id, HttpRequest request, String authHeader, Map<String, List<String>> requestHeaders, HttpCore.RequestBody requestBody) { + if (request == null) { + throw new IllegalArgumentException("HttpRequest cannot be null"); + } /* duplicating if necessary, ensure lower-case versions of header names are present */ Map<String, List<String>> normalisedHeaders = new HashMap<String, List<String>>(); // ... rest of the methodThis addition will help prevent potential null pointer exceptions and make the method more robust.
lib/src/test/java/io/ably/lib/test/rest/RestAuthTest.java (3)
1381-1382: Approved: Good refactoring to useHttpRequestThe change from
HttpURLConnectiontoHttpRequestis a good refactoring step. It increases the abstraction level, which can improve flexibility and testability.Consider updating the method name from
onRawHttpRequesttoonHttpRequestto better reflect the new parameter type and maintain consistency with the abstraction level.
1446-1447: Approved: Consistent refactoringThe change is consistent with the previous one, which is good for maintaining code uniformity.
To reduce code duplication, consider extracting the common
RawHttpListenerimplementation into a separate method or class. This would make the test code more DRY (Don't Repeat Yourself) and easier to maintain. For example:private RawHttpListener createMessageCapturingListener(final Message[] messages) { return new RawHttpListener() { @Override public HttpCore.Response onRawHttpRequest(String id, HttpRequest request, String authHeader, Map<String, List<String>> requestHeaders, HttpCore.RequestBody requestBody) { try { if(testParams.useBinaryProtocol) { messages[0] = MessageSerializer.readMsgpack(requestBody.getEncoded())[0]; } else { messages[0] = MessageSerializer.readMessagesFromJson(requestBody.getEncoded())[0]; } } catch (AblyException e) { e.printStackTrace(); fail("Unexpected exception"); } return null; } @Override public void onRawHttpResponse(String id, String method, HttpCore.Response response) {} @Override public void onRawHttpException(String id, String method, Throwable t) {} }; }Then you can use this method in both test cases:
options.httpListener = createMessageCapturingListener(messages);This approach would make the tests more maintainable and reduce the risk of inconsistencies between similar test setups.
Line range hint
1-1844: Overall assessment: Good refactoring with room for improvementThe changes in this file are part of a broader refactoring effort to use
HttpRequestinstead ofHttpURLConnection. This is a positive change that increases the abstraction level and potentially improves flexibility and testability.Key points:
- The changes are consistent across the two modified sections.
- The refactoring doesn't appear to alter the functionality of the tests.
- There's an opportunity to reduce code duplication by extracting the common
RawHttpListenerimplementation.Consider reviewing the entire test suite for similar patterns that could benefit from this refactoring. This could lead to a more maintainable and consistent test codebase overall.
network-client-core/src/main/java/io/ably/lib/network/WebSocketEngineFactory.java (1)
9-15: Consider logging when no WebSocket engines are available.When neither the OkWebSocket engine nor the default engine is available, an
IllegalStateExceptionis thrown without any logging. Adding a log statement before throwing the exception can aid in debugging and provide clearer context in logs.You might add logging like this:
if (defaultFactory != null) return defaultFactory; +// Log a warning or error before throwing the exception +System.err.println("No WebSocket engines are available."); throw new IllegalStateException("No engines are available");network-client-default/src/main/java/io/ably/lib/network/DefaultWebSocketClient.java (1)
70-81: Document deprecation plans for Android versions below API 24The override of
onSetSSLParametersincludes a workaround for Android versions below API 24. To maintain clarity, consider documenting when this workaround can be removed and use the@Deprecatedannotation to indicate future deprecation.For example:
/** * ... * @deprecated Since API level 24 supports this method. This workaround can be removed when minSdkVersion >= 24. */ @Deprecated @Override protected void onSetSSLParameters(SSLParameters sslParameters) { // Existing code }network-client-default/src/main/java/io/ably/lib/network/DefaultHttpCall.java (2)
125-130: Log exceptions when closing theInputStreamSilently ignoring exceptions can make debugging difficult. If an
IOExceptionoccurs while closing theInputStream, it should be logged or appropriately handled to aid in diagnosing potential resource leaks or underlying issues.Consider logging the exception:
} finally { if (is != null) { try { is.close(); } catch (IOException e) { - // Ignored + // Log the exception + e.printStackTrace(); // Replace with a proper logging mechanism } } }
52-56: Reevaluate callingcancel()in thefinallyblockCalling
cancel()in thefinallyblock of theexecutemethod disconnects theHttpURLConnectionregardless of whether the operation completed successfully. This might interrupt the response processing prematurely. Consider removing thecancel()call here and managing the connection lifecycle more precisely.lib/src/main/java/io/ably/lib/transport/WebSocketTransport.java (1)
248-249: Remove hardcoded 'remote' value in log messageIn the
onClosemethod, theremoteparameter has been removed, but the log statement still includesremote = falsehardcoded. This could lead to confusion when interpreting logs. Consider removing theremotevalue from the log message.Apply this diff to update the log statement:
- Log.d(TAG, "onClose(): wsCode = " + wsCode + "; wsReason = " + wsReason + "; remote = " + false); + Log.d(TAG, "onClose(): wsCode = " + wsCode + "; wsReason = " + wsReason);

- Add JavaDoc comments to the interface and its methods to improve documentation:
/** * Represents an HTTP call operation. */ public interface HttpCall { /** * Executes the HTTP call. * * @return The response from the HTTP call. */ HttpResponse execute(); /** * Cancels the ongoing HTTP call. */ void cancel(); }
- Consider specifying exception handling in the method signatures. For example:
HttpResponse execute() throws IOException, HttpException;To verify the usage of
HttpResponsein the codebase, please run the following script:This script will help us understand if
HttpResponseis properly defined and used across the project, which is crucial for the correct implementation of this interface.network-client-core/src/main/java/io/ably/lib/network/HttpEngine.java (2)

- It takes a
HttpEngineConfigparameter, allowing for customized configurations.- It returns a new instance of
DefaultHttpEngine, adhering to the factory method's responsibility.- The method is concise and follows the Single Responsibility Principle.
1-14: Verify imports and consider adding documentation.The
DefaultHttpEngineFactoryclass is well-structured and aligns with the PR objectives. However, there are a couple of points to consider:
There are no import statements in this file. Please verify that all referenced types (
HttpEngineFactory,HttpEngine,HttpEngineConfig,EngineType) are either in the same package or injava.lang. If not, add the necessary imports.Consider adding Javadoc comments to the class and methods. This would improve code documentation and make it easier for other developers to understand and use this factory.
To check for potential missing imports, run the following command:
The factory pattern implemented here provides a good abstraction for creating HTTP engines. To further improve the design:
- Consider using dependency injection for the
HttpEngineConfigif it's used across multiple components.- If there are plans for multiple engine types, you might want to create an abstract factory or use the Strategy pattern to allow for runtime selection of different engine types.

getRequestParammethod has been correctly updated to usereq.url.getQuery()instead ofreq.conn.getURL().getQuery(). This change is consistent with the earlier modifications to theRawHttpRequestclass, where theconnfield was removed and replaced with aurlfield.This update maintains the method's functionality while adhering to the new, more abstract representation of HTTP requests. It's a good example of ensuring consistency across the codebase during refactoring.

248-249: Consider retaining or documenting the removal of theremoteparameterThe
onClosemethod no longer includes theremoteparameter, which previously indicated whether the close was initiated remotely or locally. This information might be valuable for debugging or logging purposes.Consider either:
- Retaining the
remoteparameter if it's still available from the WebSocket implementation.- Documenting the reason for its removal if it's no longer relevant or available.

1-1: Summary of changes and potential impactThe main changes in this file revolve around the removal of the
Proxyparameter from thehttpExecutemethod. This simplification of the method signature is consistently applied throughout the file. The addition of theHttpRequestimport suggests that some of the functionality may have been moved to this class.These changes appear to be part of a larger refactoring effort to decouple HTTP and WebSocket engines, as mentioned in the PR objectives. While the changes look good overall, it's important to ensure that proxy functionality hasn't been lost in the process.
Consider the following points:
- Verify that proxy handling has been moved to an appropriate place in the HTTP request chain.
- Ensure that all tests related to proxy functionality are still valid and have been updated or moved as necessary.
- Update the documentation to reflect these changes in the HTTP handling process.
- If the
HttpRequestclass now handles some of the functionality previously inhttpExecute, consider adding or updating tests for this class.

4-8: LGTM: New imports align with refactoring objectivesThe addition of new WebSocket-related imports and
ClientOptionsUtilsaligns well with the PR's objective of decoupling HTTP and WebSocket engines. This change sets the foundation for a more modular and flexible WebSocket implementation.Also applies to: 15-15
81-89: LGTM: Improved WebSocket connection setupThe introduction of
WebSocketEngineFactoryandWebSocketEngineConfigenhances the flexibility and configurability of the WebSocket connection setup. This aligns well with the PR's objective of decoupling HTTP and WebSocket engines and allows for easier implementation swapping in the future.Also applies to: 97-98
138-138: LGTM: Simplified send logic with improved error handlingThe
sendmethod has been refactored to use thewebSocketClient.send()method, simplifying the implementation. The addition ofNotConnectedExceptionhandling enhances the robustness of the error management in the transport layer.Also applies to: 143-143, 145-145
191-191: LGTM: Improved WebSocket event handlingThe new
WebSocketHandlerclass implementsWebSocketListener, providing a more standardized and organized approach to handling WebSocket events. The updated methods (onOpen,onClose,onError) and the addition ofonOldJavaVersionDetectedenhance the robustness of the WebSocket connection management.Also applies to: 201-203, 206-209, 248-290, 294-296
288-290: LGTM: Enhanced error handling inonErrorThe
onErrormethod now accepts aThrowableinstead of anException, making it more versatile in handling various types of errors. The simplified error message creation improves readability while still providing necessary information for debugging.
369-369: LGTM: Updated activity timer expiry handlingThe
onActivityTimerExpirymethod has been updated to usewebSocketClient.cancel(), which aligns with the overall refactoring of the WebSocket handling. This change maintains the existing functionality while integrating with the new WebSocket implementation.
91-93:⚠️ Potential issueConsider specifying TLS version for enhanced security
The SSL context initialization still uses
SSLContext.getInstance("TLS"), which may default to older, less secure protocols. As mentioned in a previous review comment and flagged by static analysis, it's recommended to specifyTLSv1.2or higher for better security.Consider applying this change:
- SSLContext sslContext = SSLContext.getInstance("TLS"); + SSLContext sslContext = SSLContext.getInstance("TLSv1.2");lib/src/test/java/io/ably/lib/test/rest/HttpTest.java (2)
11-11: Import addition looks good.The addition of the
io.ably.lib.network.HttpRequestimport is consistent with the refactoring of the HTTP functionality. This change suggests that theHttpRequestclass is now being utilized in the test file.
141-146: Method signature update looks good, but verify proxy handling.The removal of the
Proxy proxyparameter from thehttpExecutemethod signature simplifies the method and is consistently applied. This change suggests that proxy handling has been moved elsewhere in the HTTP request chain.To ensure that proxy functionality hasn't been lost, please run the following script to check for proxy handling in other parts of the codebase:

248-286: Consider simplifying the onClose methodThe
onClosemethod uses a switch statement with several fall-through cases. Consider simplifying this logic by grouping similar cases or using a more concise approach, such as a map of error codes to reasons. This could improve readability and maintainability.Here's a potential simplification using a map:
private static final Map<Integer, ErrorInfo> closeReasonMap = Map.of( CLOSE_NORMAL, ConnectionManager.REASON_DISCONNECTED, GOING_AWAY, ConnectionManager.REASON_DISCONNECTED, REFUSE, ConnectionManager.REASON_REFUSED, POLICY_VALIDATION, ConnectionManager.REASON_REFUSED, TOOBIG, ConnectionManager.REASON_TOO_BIG ); @Override public void onClose(final int wsCode, final String wsReason) { Log.d(TAG, "onClose(): wsCode = " + wsCode + "; wsReason = " + wsReason); ErrorInfo reason = closeReasonMap.getOrDefault(wsCode, ConnectionManager.REASON_FAILED); connectListener.onTransportUnavailable(WebSocketTransport.this, reason); dispose(); }This approach reduces the complexity of the method while maintaining the same logic.

18-30: Consider updating minSdkVersionThe current
minSdkVersionis set to 19, which corresponds to Android 4.4 (KitKat), released in 2013. While this ensures wide compatibility, it may limit the use of newer Android features and optimizations.Consider increasing the
minSdkVersionto a more recent version, such as 21 (Android 5.0 Lollipop) or higher, depending on your user base and required features. This could allow for more modern API usage and potentially simplify development.Before making this change, analyze your user base to ensure you're not excluding a significant portion of your users.

1-7: LGTM: Plugin management configuration looks good.The added
pluginManagementblock is correctly structured and includes commonly used repositories (Google, Gradle Plugin Portal, and Maven Central). This configuration ensures that Gradle can properly resolve plugins required for the project.build.gradle (1)
5-6: LGTM! Consider updating plugin versions and clarify Android Library plugin usage.The addition of Lombok and Android Library plugins aligns well with the PR's objective of improving code structure and maintainability. Setting
apply falseallows for selective application in subprojects, which is a good practice.However, I have a few suggestions:
The Lombok plugin version (5.0.1) is quite old. Consider updating to the latest version (currently 8.4) for potential bug fixes and new features.
The Android Library plugin version (4.2.2) is also outdated. The latest version is 8.2.0. Updating could provide access to newer Android features and optimizations.
The introduction of the Android Library plugin is interesting. Could you provide more context on how Android support fits into the project's roadmap? This wasn't mentioned in the PR objectives.
To check for the latest versions of these plugins, you can run:
android/build.gradle (4)
1-3: LGTM: Updated to use the plugins DSLThe change from

102-107: LGTM: Appropriate configuration for test dependenciesThe configuration to exclude
hamcrest-coreand extendtestImplementationtoandroidTestImplementationis appropriate. This helps avoid potential conflicts and efficiently shares test dependencies between unit tests and instrumented tests.The overall structure of the build file remains clean and well-organized, which is commendable.
86-93: LGTM: Enhanced test dependencies, but consider version updatesThe addition of new test dependencies significantly improves the project's testing capabilities. This is a positive change that will enhance the robustness of the codebase.
However, some of the dependencies are using older versions:
- JUnit 4.12 (latest is 4.13.2)
- Mockito 1.10.19 (latest in 1.x series is 1.10.19, but 5.x is available)
- NanoHTTPD 2.3.0 (latest is 2.3.1)
Consider updating these to their latest versions for potential bug fixes and improvements.
Please run the following script to check for the latest versions of these test dependencies:
#!/bin/bash # Description: Check for the latest versions of the new test dependencies # Function to fetch the latest version fetch_latest_version() { local group=$1 local artifact=$2 curl -s "https://search.maven.org/solrsearch/select?q=g:${group}+AND+a:${artifact}&rows=1&wt=json" | jq -r '.response.docs[0].latestVersion' } # Check JUnit latest_junit=$(fetch_latest_version "junit" "junit") echo "junit - Current: 4.12, Latest: $latest_junit" # Check Hamcrest latest_hamcrest=$(fetch_latest_version "org.hamcrest" "hamcrest-all") echo "hamcrest-all - Current: 1.3, Latest: $latest_hamcrest" # Check NanoHTTPD latest_nanohttpd=$(fetch_latest_version "org.nanohttpd" "nanohttpd") echo "nanohttpd - Current: 2.3.0, Latest: $latest_nanohttpd" # Check Mockito latest_mockito=$(fetch_latest_version "org.mockito" "mockito-core") echo "mockito-core - Current: 1.10.19, Latest: $latest_mockito" # Check ConcurrentUnit latest_concurrentunit=$(fetch_latest_version "net.jodah" "concurrentunit") echo "concurrentunit - Current: 0.4.2, Latest: $latest_concurrentunit" # Check SLF4J latest_slf4j=$(fetch_latest_version "org.slf4j" "slf4j-simple") echo "slf4j-simple - Current: 1.7.30, Latest: $latest_slf4j"
80-85: LGTM: New dependencies align with PR objectivesThe addition of new dependencies (msgpack-core, gson, vcdiff-core) and project dependencies (network-client-core, network-client-default) aligns well with the PR's objective of decoupling HTTP and WebSocket engines. This modular approach should improve maintainability.
However, it's important to ensure that the specific versions of these dependencies are up-to-date and don't have any known security vulnerabilities.

network-client-core/gradle.properties (1)
1-3: LGTM! Well-defined Gradle properties for the new module.The
gradle.propertiesfile for thenetwork-client-coremodule is correctly set up with the following properties:
POM_ARTIFACT_ID: Correctly identifies the artifact as "network-client-core".POM_NAME: Provides a clear, human-readable name "Network Core".POM_PACKAGING: Specifies the standard JAR packaging for Java libraries.These properties are essential for proper identification and packaging of the module in the build process and when published to repositories.
network-client-okhttp/gradle.properties (1)
1-3: LGTM! Properties are well-defined for the new module.The gradle.properties file for the new 'network-client-okhttp' module is correctly set up with appropriate values:
- POM_ARTIFACT_ID is correctly set to 'network-client-okhttp'.
- POM_NAME provides a clear description: 'OkHttp Client'.
- POM_PACKAGING is appropriately set to 'jar' for a Java library.
These properties align well with the PR objectives of decoupling HTTP and WebSocket engines by creating a separate module for the OkHttp client. This separation will enhance the project's structure and facilitate easier management of different network client implementations.
build.gradle (2)
5-7: Overall assessment of plugin additionsThe addition of these three plugins (Lombok, Android Library, and Maven Publish) aligns well with the PR objectives of refactoring and improving the project structure. These changes suggest a move towards:
- Reducing boilerplate code (Lombok)
- Better support for Android library development
- Improved artifact publishing capabilities
These additions will likely facilitate the decoupling of HTTP and WebSocket engines as mentioned in the PR objectives, by providing tools for cleaner code structure and easier module management.
While the plugin additions are approved in principle, please consider the version update suggestions in the previous comments to ensure you're using the most up-to-date and compatible versions of these plugins.
6-6: 🛠️ Refactor suggestionUpdate Android Library plugin version and verify compatibility.
The Android Library plugin is added, which is necessary for building Android libraries. However, there are important considerations:
- The current version (4.2.2) is significantly outdated. The latest version as of September 2024 is 8.1.2. Updating to the latest version can provide access to new features, performance improvements, and bug fixes.
- The
apply falsedirective is correctly used here, allowing subprojects to apply this plugin as needed.Consider updating the plugin declaration:
-id 'com.android.library' version '4.2.2' apply false +id 'com.android.library' version '8.1.2' apply falseBefore updating, please verify compatibility with your project's Gradle version and other dependencies. Run the following script to check the current Gradle version:
gradle.properties (5)
4-9: LGTM! Project description and SCM details are well-defined.The project description is concise and informative. The SCM URLs are consistent and follow the expected format for GitHub repositories. These properties are crucial for generating accurate POM files for Maven Central publishing.
11-13: LGTM! License information is accurate and complete.The license information is well-defined, using the Apache Software License, Version 2.0. The license URL correctly points to the official Apache website. These properties are essential for compliance and transparency in open-source projects.
15-18: LGTM! Developer information and Sonatype staging profile are correctly defined.The developer information is consistent with the project's group ID. Using the organization name (Ably) instead of an individual developer is appropriate for a company-maintained project. The Sonatype staging profile matches the group ID, which is correct for Maven Central publishing.
19-20: Existing Gradle and Android properties remain unchanged.The
org.gradle.jvmargsandandroid.useAndroidXproperties were not modified in this PR. They continue to provide important configuration for the Gradle build process and Android project setup.
1-20: Summary: Gradle properties updated with comprehensive project metadata.The changes to
gradle.propertiessignificantly enhance the project's metadata, particularly for Maven Central publishing. New properties have been added to define the project's group ID, version, description, SCM details, license information, and developer details. These additions follow best practices for open-source Java projects and will improve the project's visibility and usability when published to Maven repositories.The existing Gradle and Android-specific properties remain unchanged, maintaining the current build configuration.
Overall, these changes represent a positive improvement to the project's build configuration and metadata.

12-12: LGTM! Good addition to .gitignoreAdding
lombok.configto .gitignore is a good practice. This file often contains project-specific Lombok configurations that shouldn't be shared across different development environments.Consider grouping similar entries together for better organization. For instance, you could move
lombok.confignext to other configuration files or IDE-related entries.network-client-core/src/main/java/io/ably/lib/network/FailedConnectionException.java (1)
1-7: LGTM! Consider adding more flexibility and documentation.The implementation of
FailedConnectionExceptionis correct and follows good practices. Here are some suggestions for improvement:
Consider adding a constructor that accepts both a custom message and a cause:
public FailedConnectionException(String message, Throwable cause) { super(message, cause); }This would allow for more informative exception messages.
The choice of extending
RuntimeExceptionmakes this an unchecked exception. Ensure this aligns with your error handling strategy, as it doesn't force callers to explicitly handle the exception.Add Javadoc comments to describe the class purpose and constructor usage. For example:
/** * Exception thrown when a network connection fails. */ public class FailedConnectionException extends RuntimeException { /** * Constructs a new FailedConnectionException with the specified cause. * * @param cause the cause of the connection failure */ public FailedConnectionException(Throwable cause) { super(cause); } }Consider making the class
finalif you don't intend for it to be subclassed:public final class FailedConnectionException extends RuntimeException { // ... }lib/src/main/java/io/ably/lib/types/AblyException.java (1)
54-55: Approve with suggestion: Add null check fort.getCause()The new condition for handling
FailedConnectionExceptionis a good addition to the exception handling logic. It correctly preserves the underlying cause and usesHostFailedException, which is consistent with how other connection-related exceptions are handled.However, to improve robustness, consider adding a null check for
t.getCause(). This will prevent potentialNullPointerExceptions if the cause is null.Here's a suggested improvement:
if (t instanceof FailedConnectionException) - return new HostFailedException(t.getCause(), ErrorInfo.fromThrowable(t.getCause())); + return new HostFailedException(t.getCause() != null ? t.getCause() : t, + ErrorInfo.fromThrowable(t.getCause() != null ? t.getCause() : t));This change ensures that if
t.getCause()is null, the original exceptiontis used instead.gradle/libs.versions.toml (1)
51-51: Approved: Addition of Lombok pluginThe addition of the Lombok plugin is consistent with the introduction of Lombok to the project. This will enable the use of Lombok's annotations to reduce boilerplate code.
Consider updating the project documentation to reflect the introduction of Lombok and provide guidelines on its usage within the project. This will help maintain consistency and inform other developers about this new tool in the project's ecosystem.

3-3: LGTM: New import statement is appropriate.The addition of the import statement for
FailedConnectionExceptionis necessary for the new exception handling logic and follows the existing import style in the file.
3-3: Overall: Good enhancement to exception handlingThe changes in this file improve the exception handling capabilities of the
AblyExceptionclass. By adding specific handling forFailedConnectionException, the code now provides more granular error information for this type of failure. This enhancement is consistent with the existing pattern of creatingHostFailedExceptioninstances for connection-related issues.The changes maintain the method's contract and integrate well with the existing code structure. This improvement will likely lead to more accurate error reporting and easier debugging of connection failures in the Ably Java library.

sendmethod appropriately use the newwebSocketClientreference for sending messages. This update ensures compatibility with the new WebSocket implementation while maintaining the existing logic for both binary and text message formats.Also applies to: 143-143
Line range hint
191-295: LGTM: Improved WebSocket handling with WebSocketHandlerThe replacement of
WsClientwithWebSocketHandleris a significant improvement:
- Implementing
WebSocketListenerinstead of extendingWebSocketClientprovides better separation of concerns and flexibility.- Updated method signatures (
onOpen,onClose,onError) align with the new WebSocket implementation.- The addition of
onWebsocketPingallows for more efficient connection management without relying on Ably heartbeats.- The new
onOldJavaVersionDetectedmethod provides better error handling for SSL-related issues on older Java versions.These changes align well with the PR objective of decoupling the WebSocket engine and should improve the overall robustness of the WebSocket implementation.
369-369: LGTM: Updated connection closure on timeoutThe change from
wsConnection.close()towebSocketClient.cancel()is consistent with the new WebSocket implementation. This update ensures that the connection is properly closed using the appropriate method when an activity timeout occurs.
Line range hint
1-382: Overall assessment: Successful refactoring with improved modularityThe changes in this file successfully achieve the PR objective of decoupling the WebSocket engine. Key improvements include:
- Introduction of a more flexible WebSocket engine configuration.
- Replacement of
WsClientwithWebSocketHandler, providing better separation of concerns.- Enhanced WebSocket event handling, including support for WebSocket pings.
- Consistent updates throughout the file to use the new WebSocket client implementation.
These changes should result in a more maintainable and extensible WebSocket implementation. The only remaining point of attention is the SSL context initialization, which was addressed in a previous comment.
Great work on this refactoring!

There was a problem hiding this comment.
Engine terminology used across interfaces and classes is confusing. Can we replace naming with either Lib or Client instead.
Also, some of the intermediate interfaces/calsses can be entirely removed leading to the creation of either defaultHTTPClient or OkHttpClient.
I will post more information regarding this 👍

network-client-core/src/main/java/io/ably/lib/network/WebSocketEngine.java (2)
3-5: Enhance the Javadoc comment for better documentation.While the current comment provides a basic description, it could be more informative. Consider expanding it to include:
- A more detailed explanation of the interface's purpose.
- Information about the
WebSocketListenerparameter.- Description of the returned
WebSocketClient.Here's a suggested improvement:
/** * Defines a factory for creating WebSocket clients bound to specific URLs. * This interface allows for flexible implementation of WebSocket creation strategies. * * @see WebSocketClient * @see WebSocketListener */
6-8: LGTM: Interface declaration and method signature are well-designed.The
WebSocketEngineinterface and itscreatemethod are appropriately defined for a factory pattern. The method signature clearly indicates its purpose and parameters.Consider adding Javadoc for the
createmethod:/** * Creates a WebSocket client bound to the specified URL. * * @param url The URL to which the WebSocket should connect. * @param listener The listener to handle WebSocket events. * @return A new WebSocketClient instance. */ WebSocketClient create(String url, WebSocketListener listener);This addition would provide clearer documentation for implementers and users of this interface.
network-client-core/src/main/java/io/ably/lib/network/HttpCall.java (2)
9-12: LGTM: Well-definedexecute()method with minor documentation typo.The
execute()method is appropriately defined for synchronous HTTP request execution. However, there's a small typo in the documentation.Please correct the typo in the documentation:
- * Synchronously execute Http request and return response from te server + * Synchronously execute Http request and return response from the server
1-18: Excellent interface design: Concise, focused, and aligned with PR objectives.The
HttpCallinterface is well-designed, adhering to the Single Responsibility Principle and providing a clear contract for implementers. It aligns perfectly with the PR objectives of decoupling HTTP functionality, allowing for easier implementation swapping and improved maintainability.Key strengths:
- Focused on a single responsibility (HTTP request execution and cancellation).
- Clear and concise method signatures.
- Explicit thread-safety requirement.
- Easily mockable for unit testing.
This interface forms a solid foundation for the refactoring effort to decouple HTTP and WebSocket engines.
Consider adding a method to check the status of the HTTP call (e.g.,
isExecuted(),isCancelled()), which could be useful for more granular control and error handling in client code.network-client-core/src/main/java/io/ably/lib/network/HttpEngine.java (2)
9-12: Approve method with suggestion for improved documentation.The
callmethod signature is well-defined and aligns with the interface's purpose. However, the Javadoc comment could be more descriptive.Consider expanding the Javadoc comment to provide more details:
/** * Makes a cancelable HTTP request. * * @param request The HTTP request to be executed * @return A cancelable HTTP request call */ HttpCall call(HttpRequest request);
14-18: Approve method with suggestion for concise documentation.The
isUsingProxymethod is well-defined and its purpose is clear. The Javadoc comment is good but could be more concise.Consider simplifying the Javadoc comment:
/** * @return true if the engine is configured to use a proxy, false otherwise */ boolean isUsingProxy();network-client-core/src/main/java/io/ably/lib/network/WebSocketClient.java (4)
3-7: Enhance interface documentation for clarity.The interface documentation provides a basic explanation, but it could be more comprehensive. Consider adding information about:
- The lifecycle of the WebSocket connection.
- Any specific threading or concurrency considerations.
- How error handling is expected to be implemented.
- Any dependencies or prerequisites for using this interface.
This additional context will help implementers better understand the expected behavior and responsibilities of the
WebSocketClient.
9-12: Enhanceconnect()method documentation.While the current documentation is concise, it could be more informative. Consider adding:
- Information about possible exceptions that might be thrown.
- The expected state of the connection after this method is called.
- Whether this method is blocking or non-blocking.
- Any prerequisites before calling this method.
Example:
/** * Establishes a connection to the WebSocket server. * * @throws IOException if there's an error during connection establishment * @throws IllegalStateException if the client is already connected * @return void This method doesn't return anything, but the connection state should be checked separately. */ void connect();
14-17: Enhanceclose()method documentation.The current documentation is brief. Consider expanding it to include:
- The behavior if the connection is already closed or was never opened.
- Whether this method is blocking or non-blocking.
- Any exceptions that might be thrown.
- The state of the WebSocketClient after this method is called.
Example:
/** * Sends the closing handshake to the WebSocket server. * This method initiates a graceful shutdown of the connection. * * @throws IOException if there's an error during the closing handshake * @throws IllegalStateException if the connection is already closed or was never opened */ void close();
1-50: Overall assessment of the WebSocketClient interfaceThe
WebSocketClientinterface provides a solid foundation for implementing WebSocket functionality in the Ably Java library. It covers the essential operations needed for managing a WebSocket connection, including connecting, sending messages, and closing the connection.Strengths:
- Clear and concise method names that follow Java conventions.
- Separation of concerns between different connection operations.
- Support for both binary and text message sending.
Areas for improvement:
- Enhance method documentation to provide more detailed information about behavior, exceptions, and constraints.
- Consider adding parameter validation for methods that accept parameters.
- Potentially add methods for checking connection state and handling connection events.
Consider adding the following methods to make the interface more comprehensive:
/** * Checks if the WebSocket connection is currently open and ready for communication. * * @return true if the connection is open, false otherwise. */ boolean isConnected(); /** * Sets a listener for WebSocket events such as message received, connection closed, etc. * * @param listener The WebSocketListener to handle events. */ void setListener(WebSocketListener listener);These additions would provide users of the interface with more control and information about the WebSocket connection state and events.
network-client-core/src/main/java/io/ably/lib/network/WebSocketListener.java (4)
5-8: Enhance the interface Javadoc comment.While the interface name is clear, the Javadoc comment could be more descriptive. Consider expanding it to provide more context about the interface's purpose and usage.
Suggested improvement:
/** * WebSocket Listener interface * * This interface defines callback methods for handling various WebSocket events. * Implementations of this interface can be used to respond to connection events, * incoming messages, and error conditions in a WebSocket communication. */ public interface WebSocketListener {
31-34: Improve method name and enhance Javadoc foronWebsocketPing.
- The method name should follow Java naming conventions. Consider changing it to
onWebSocketPing.- The Javadoc could be more informative about the expected behavior when a ping frame is received.
Suggested improvements:
/** * Callback for receiving a ping frame from the WebSocket server. * This method is called when a ping frame is received, if supported by the WebSocket engine. * Implementations may use this to update connection status or perform keep-alive actions. */ void onWebSocketPing();
36-41: Enhance Javadoc foronClosemethod.While the method signature is clear, the Javadoc could be more informative about the parameters and their significance.
Suggested improvement:
/** * Called after the WebSocket connection has been closed. * * @param code The status code indicating the reason for closure (as per WebSocket protocol). * @param reason A human-readable string explaining the reason for closure. */ void onClose(int code, String reason);
53-57: Consider generalizing method name and enhance Javadoc foronOldJavaVersionDetected.
- The method name is very specific. Consider a more general name like
onSecurityConstraintViolationto cover other potential security issues.- The Javadoc could be more informative about the implications and expected actions when this method is called.
Suggested improvements:
/** * Called when a security constraint violation is detected, such as inability to use secure HTTPS algorithms. * This method is typically invoked when the runtime environment cannot support TLS 1.2 or higher, * which may occur on older Java versions. * * @param throwable The exception providing details about the security constraint violation. */ void onSecurityConstraintViolation(Throwable throwable);If you prefer to keep the current method name, at least enhance the Javadoc as suggested above.
CONTRIBUTING.md (2)
44-52: Improve Markdown formatting for the code blockThe descriptions of the supported engines are clear and informative. The code snippet for replacing the default engine with the OkHttp engine is helpful. However, the code block is not properly formatted according to Markdown standards.
Please update the code block formatting to use triple backticks (```) instead of single backticks. This will ensure proper syntax highlighting and improve readability. For example:
```kotlin implementation("io.ably:ably-java:$ABLY_VERSION") { exclude(group = "io.ably", module = "network-client-default") } runtimeOnly("io.ably:network-client-okhttp:$ABLY_VERSION")<details> <summary>🧰 Tools</summary> <details> <summary>🪛 Markdownlint</summary><blockquote> 47-47: Expected: indented; Actual: fenced Code block style (MD046, code-block-style) </blockquote></details> </details> --- `54-64`: **Improve list formatting for consistency** The instructions for adding a new network engine are clear and concise. They provide a good overview of the process, which is helpful for contributors. To maintain consistency with the rest of the document, please adjust the list formatting. Remove the extra indentation for list items. For example: ```markdown To add a new network engine, follow these steps: 1. **Implement the interfaces**: - Implement the `HttpEngineFactory` and `WebSocketEngineFactory` interfaces for your custom engine. 2. **Register the engine**: - Modify the `getFirstAvailable()` methods in these interfaces to include your new implementation.This change will ensure that the list formatting is consistent throughout the document.
