Checklist

General

Server

  • Important: I implemented the changes with a very good performance and prevented too many (unnecessary) and too complex database calls.
  • I strictly followed the principle of data economy for all database calls.
  • I strictly followed the server coding and design guidelines.
  • I added multiple integration tests (Spring) related to the features (with a high test coverage).
  • I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).
  • I documented the Java code using JavaDoc style.

Client

  • Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data (e.g. using paging).
  • I strictly followed the principle of data economy for all client-server REST calls.
  • I strictly followed the client coding and design guidelines.
  • Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
  • I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
  • I added authorities to all new routes and checked the course groups for displaying navigation elements (links, buttons).
  • I documented the TypeScript code using JSDoc style.
  • I added multiple screenshots/screencasts of my UI changes.
  • I translated all newly inserted strings into English and German.

Changes affecting Programming Exercises

  • High priority: I tested all changes and their related features with all corresponding user types on a test server configured with the integrated lifecycle setup (LocalVC and LocalCI).

Motivation and Context

We want to give admins the possibility to pause build agents. Pausing a build agent means that the build agent will no longer process any build jobs. If the agent is currently processing build jobs, there will be a grace period where it will wait for the jobs to finish. Afterward, the jobs will be canceled and added back to the queue. The canceled jobs won't produce a result.

Steps for Testing

Prerequisites:

  • 1 Admin
  • 1 Student
  • 1 Java exercise

Scenario 1: Build agent with no running jobs

  1. Make sure that code submissions work normally.
  2. Go to Build Agents > Click on a build agent > Pause
  3. Submit once more and make sure that the pause agent is not processing the job (in multi node setup, you may have to submit a couple of time to make sure that build agent is not processing)
  4. Resume Build agent > Submit a few times make sure that the agent is processing jobs.

Scenario 2: Build agent processing jobs (shorter than grace period)

  1. Make a submission > Wait around 5-10 secs and then pause the build agent processing the job (you can find which agent in the Build overview page)
  2. Check that the job wasn't canceled and that it produces a result

Scenario 3: Build agent processing jobs (longer than grace period)

  1. Edit a build script of a programming Exercise to make it sleep for 20 secs (add sleep 20 somewhere in the bash script)
  2. Make a submission for that exercise and pause the build agent
  3. Make sure that the job is canceled (canceled jobs will be visible in the build agent details view but won't be visible in the build overview page_

Walkthrough

The changes to the SharedQueueProcessingService class introduce mechanisms for pausing and resuming the build agent's operations. New methods, pauseBuildAgent() and resumeBuildAgent(), have been added to manage the agent's state safely. The job processing logic has been updated to respect the paused state, preventing job execution when paused. A scheduled task has been introduced to check for available threads and process jobs periodically. The constructor now requires a TaskScheduler parameter to facilitate scheduling tasks. Additional imports support the new functionality.

4-8: LGTM!

The new BuildAgentStatus enum provides a more descriptive representation of the build agent's status. The enum values cover the essential states, and the naming convention follows the coding guidelines.


16-16: Verify the impact of the status property type change.

Updating the status property to use the BuildAgentStatus enum aligns with the introduction of the new enum. However, ensure that all references to the status property throughout the codebase are updated to handle the new enum type instead of a boolean.

Run the following script to verify the status property usage:

Verification successful

Verification successful: Status property change implemented correctly

The change from a boolean to the BuildAgentStatus enum for the status property has been implemented correctly and consistently across the codebase. The enum provides more expressive states (ACTIVE, PAUSED, IDLE) than a simple boolean, improving the clarity of the build agent's status representation. No issues or inconsistencies were found in the implementation.

15-15: LGTM!

The localization string for the "paused" state is correctly added.


19-25: Looks good!

The new "alerts" object provides clear and informative localization strings for various build agent actions and states. The messages accurately convey the success or failure of pause and resume requests, as well as the requirement for a build agent name.


26-26: LGTM!

The localization string for the "pause" action is correctly added.


27-27: LGTM!

The localization string for the "resume" action is correctly added.

src/main/webapp/i18n/de/buildAgents.json (5)

15-15: LGTM!

The new key-value pair for the "paused" state is correctly formatted and the German translation "Angehalten" is appropriate. The translation also follows the informal "dutzen" form, as per the coding guidelines.


18-18: LGTM!

The new key-value pair for the number of build jobs running is correctly formatted and the German translation "Build Jobs laufen" is appropriate. The translation also follows the informal "dutzen" form, as per the coding guidelines.


19-25: LGTM!

The new "alerts" object and its key-value pairs for various build agent status messages are correctly formatted. The German translations provide clear feedback to the user and follow the informal "dutzen" form, as per the coding guidelines.


26-26: LGTM!

The new key-value pair for the "pause" action is correctly formatted and the German translation "Anhalten" is appropriate. The translation also follows the informal "dutzen" form, as per the coding guidelines.


27-27: LGTM!

The new key-value pair for the "resume" action is correctly formatted and the German translation "Fortsetzen" is appropriate. The translation also follows the informal "dutzen" form, as per the coding guidelines.

src/main/java/de/tum/cit/aet/artemis/buildagent/dto/BuildAgentInformation.java (2)

31-33: LGTM!

The introduction of the BuildAgentStatus enum is a great addition. It provides a more structured and descriptive way to represent the status of a build agent compared to using a boolean value. The enum states ACTIVE, IDLE, and PAUSED clearly indicate the possible states a build agent can be in.

The enum follows the naming convention of using uppercase for enum constants, which adheres to the Java coding guidelines.


14-15: Verify the usage of BuildAgentInformation in the codebase.

The change in the status field type from boolean to BuildAgentStatus enum enhances the representation of the build agent's status. This change adheres to the coding guidelines for using Java records for DTOs.

However, this is a breaking change. Please ensure that all usages of BuildAgentInformation in the codebase have been updated to accommodate the new status field type.

Run the following script to verify the usage of BuildAgentInformation:

Verification successful

Verification successful: BuildAgentStatus enum properly implemented and used.

The change from boolean to BuildAgentStatus enum in the BuildAgentInformation record has been successfully implemented across the codebase. Key points:

  • The BuildAgentStatus enum is defined with three states: ACTIVE, IDLE, and PAUSED, providing more detailed status information.
  • The new enum is consistently used in relevant parts of the codebase, including service classes and tests.
  • No occurrences of the old boolean status were found, indicating a complete migration.
  • The change appears to be backwards compatible with the overall structure of BuildAgentInformation.

This enhancement improves the representation of build agent status without introducing breaking changes.

115-121: LGTM!

The test case for pausing a build agent is well-structured and follows the coding guidelines. It correctly verifies the HTTP request method and URL, and simulates an appropriate response.


123-129: LGTM!

The test case for resuming a build agent is well-structured and follows the coding guidelines. It correctly verifies the HTTP request method and URL, and simulates an appropriate response.

src/main/webapp/app/localci/build-agents/build-agent-details/build-agent-details/build-agent-details.component.ts (5)

5-5: LGTM!

The imports for the pause and play icons follow the existing pattern and are likely used for the new pause and resume functionality.


11-11: LGTM!

The imports for AlertService and AlertType are likely used for displaying alerts related to the new pause and resume functionality.


32-33: LGTM!

The faPause and faPlay icons are declared using the camelCase naming convention, which is consistent with the existing code. They are likely used in the template for the new pause and resume functionality.


40-40: LGTM!

The AlertService is injected into the constructor and is likely used for displaying alerts related to the new pause and resume functionality.


112-159: LGTM!

The pauseBuildAgent() and resumeBuildAgent() methods follow a similar structure and logic:

  • They check if buildAgent.name exists before calling the respective service methods.
  • They use the subscribe method to handle the service call results, which is consistent with the existing code.
  • They use the AlertService to display success, error, and warning alerts based on the service call results and the presence of buildAgent.name.
  • The alert messages are localized using keys from the artemisApp.buildAgents.alerts namespace, which is consistent with the existing code.

The methods are well-structured and follow the existing patterns in the codebase.

src/main/webapp/app/localci/build-agents/build-agent-summary/build-agent-summary.component.html (1)

44-53: LGTM!

The @switch statement is a great improvement over the previous @if statement. It explicitly defines the possible states of the build agent, making the code more readable and maintainable. The translations for each state are displayed using the jhiTranslate directive, which is a good practice for internationalization.

The code segment follows the coding guidelines by using the new @switch syntax.

src/test/javascript/spec/component/localci/build-agents/build-agent-summary.component.spec.ts (2)

13-13: LGTM!

The updated import statement for BuildAgent to include BuildAgentStatus is correct and enhances the semantic clarity of the status property.


127-127: LGTM!

The changes to the status property of the BuildAgent instances from a boolean value to the BuildAgentStatus.ACTIVE enumeration value are correct. This improves the clarity and structure of the build agent status representation in the test setup.

Also applies to: 135-135

src/main/java/de/tum/cit/aet/artemis/core/web/admin/AdminBuildJobQueueResource.java (2)

215-221: LGTM!

The pauseBuildAgent method follows the REST conventions and adheres to the coding guidelines. It correctly uses the @EnforceAdmin annotation to restrict access to admin users only. The method delegates the actual pause operation to the localCIBuildJobQueueService, maintaining a clean separation of concerns. The logging statement helps with debugging and monitoring. Overall, the implementation looks good.


236-242: LGTM!

The resumeBuildAgent method is implemented correctly, following the same pattern as the pauseBuildAgent method. It adheres to the REST conventions, coding guidelines, and the principle of least privilege. The method delegates the resume operation to the localCIBuildJobQueueService, maintaining a clean separation of concerns. The logging statement aids in debugging and monitoring. The code changes look good.

src/test/javascript/spec/component/localci/build-agents/build-agent-details.component.spec.ts (10)

4-4: LGTM!

The import of throwError from rxjs is necessary for mocking error scenarios in the new test cases.


10-10: LGTM!

The imports of MockComponent and MockPipe from ng-mocks are necessary for mocking components and pipes in the test suite.


12-12: LGTM!

The imports of BuildAgent and BuildAgentStatus from app/entities/programming/build-agent.model are necessary for using these types in the test suite.


19-19: LGTM!

The imports of AlertService and AlertType from app/core/util/alert.service are necessary for using these in the new test cases.


34-35: LGTM!

The addition of pauseBuildAgent and resumeBuildAgent methods to the mockBuildAgentsService is necessary for testing the pause and resume functionalities in the new test cases. Returning an observable of an empty object is a valid mock implementation for these methods.


120-120: LGTM!

Changing the status property of the mockBuildAgent to BuildAgentStatus.ACTIVE is necessary to align with the new BuildAgentStatus enum introduced in the BuildAgent model. Using BuildAgentStatus.ACTIVE is the correct value for an active build agent.


123-125: LGTM!

Declaring the alertService and alertServiceAddAlertStub variables is necessary for injecting and spying on the AlertService in the new test cases.


135-135: LGTM!

Adding MockProvider(AlertService) to the providers array in the test module configuration is necessary for injecting a mocked instance of AlertService in the test suite.


143-144: LGTM!

Injecting AlertService and setting up a jest spy on its addAlert method is necessary for verifying the alerts triggered in the new test cases.


215-275: Excellent work on adding comprehensive test cases for the pause and resume functionalities!

The new test cases enhance the test coverage by covering important scenarios, including edge cases and error handling. The assertions verify the expected behavior by checking the alerts triggered using the alertServiceAddAlertStub. The test cases follow the AAA pattern, are well-structured, and have clear and concise descriptions.

Great job on improving the test suite!

src/main/java/de/tum/cit/aet/artemis/programming/service/localci/SharedQueueManagementService.java (4)

70-71: LGTM!

The variable declaration follows the principle of least access and has an appropriate name and type.


72-73: LGTM!

The variable declaration follows the principle of least access and has an appropriate name and type.


90-91: LGTM!

The topic is initialized correctly using the Hazelcast instance and the @PostConstruct annotation.


144-150: LGTM!

The pauseBuildAgent and resumeBuildAgent methods are implemented correctly:

  • They have clear names and single responsibilities.
  • They are concise and follow the KISS principle.
  • They are stateless and do not modify instance variables.
src/main/java/de/tum/cit/aet/artemis/buildagent/service/BuildJobManagementService.java (3)

174-175: LGTM!

The addition of the whenComplete callback to remove the build job ID from the runningFutures map is a good improvement. It ensures proper cleanup of completed or failed jobs from the tracking map, regardless of the future's completion status. The asynchronous execution of the callback is appropriate for this cleanup operation.


177-178: LGTM!

The new getRunningBuildJobIds method is a useful addition that provides a way to retrieve the IDs of currently running build jobs. Returning an immutable copy of the keys from the runningFutures map using Set.copyOf() is a good practice. It ensures that the returned set is independent of the original map and prevents any unintended modifications.


233-233: Consider the principle of least privilege.

The visibility of the cancelBuildJob method has been changed from private to package-private. While this change allows other classes within the same package to access the method directly, it also increases the coupling between classes and may lead to unintended usage or dependencies.

Please provide clarification on the reason for this visibility change. If there is no specific requirement for other classes to access this method, consider keeping it private to maintain encapsulation and adhere to the principle of least privilege.

src/test/java/de/tum/cit/aet/artemis/localvcci/LocalCIResourceIntegrationTest.java (1)

352-360: LGTM!

The test method is well-structured, follows best practices, and effectively tests the pause and resume functionality of a build agent.

src/main/webapp/app/localci/build-agents/build-agent-details/build-agent-details/build-agent-details.component.html (4)

4-19: LGTM!

The code segment is well-structured and follows best practices:

  • Proper use of flexbox for aligning elements.
  • Consistent styling of buttons with appropriate color classes and icons.
  • Translations for button labels using jhiTranslate.

43-52: Excellent use of @switch for rendering the build agent status!

The code segment correctly uses the @switch directive to conditionally render the status based on the value variable. The cases cover all possible status values, and the status messages are properly translated.


43-52: Duplicate code segment

This code segment is identical to the one reviewed earlier at line range 43-52. Skipping the review to avoid redundancy.

89-91: LGTM!

The hazelcastInstance field is properly autowired and qualified. The use of HazelcastInstance is appropriate for interacting with Hazelcast in the tests.


483-502: LGTM!

The testPauseAndResumeBuildAgent method is a well-structured test that covers the scenario of pausing and resuming a build agent. The use of Hazelcast topics for communication and the waiting for the expected state before proceeding are good practices. The verification of the latest submission ensures that the build job is processed correctly after resuming the build agent.

15-15: LGTM: New status "paused" added correctly

The addition of the "paused" status aligns with the PR objective and follows the existing pattern for status strings.


26-27: LGTM: Action strings for pause and resume added

The new "pause" and "resume" strings are concise, clear, and consistent with the existing style. They appropriately support the new build agent management features.


Line range hint 1-29: LGTM: File structure and consistency maintained

The new entries have been integrated seamlessly into the existing file structure. The JSON remains valid, and the formatting is consistent throughout the file.

src/main/webapp/i18n/de/buildAgents.json (5)

15-15: LGTM: Correct translation for "paused" status

The translation "Angehalten" for "paused" is accurate and consistent with the existing style for status translations.


19-25: LGTM: Correct and consistent translations for alerts

The translations for the new alert messages are accurate and follow the required informal "du" form where applicable. They provide clear and informative feedback to the user about the build agent status changes.


26-26: LGTM: Correct translation for "pause" action

The translation "Anhalten" for "pause" is accurate and consistent with the related "paused" status translation.


27-27: LGTM: Correct translation for "resume" action

The translation "Fortsetzen" for "resume" is accurate and consistent with the style of other action translations in this file.


26-27: Addressing past review comment: Usage of translations

@JohannesStoehr Previously, you asked where certain translations were used. The addition of "pause" and "resume" translations in this update clarifies their purpose. They are likely used for action buttons in the UI for pausing and resuming build agents.

src/main/java/de/tum/cit/aet/artemis/buildagent/service/SharedQueueProcessingService.java (4)

97-100: Thread safety ensured with volatile variables

Great job declaring isPaused and processResults as volatile. This ensures that changes to these variables are immediately visible to all threads, preventing potential data races.


192-199: Properly checking isPaused before processing build jobs

The added checks for isPaused before processing build jobs in checkAvailabilityAndProcessNextBuild() prevent the agent from processing jobs while paused, which helps avoid race conditions.


275-277: Simplify build agent status determination for readability

Consider refactoring the status assignment logic for better readability by replacing nested ternary operators with clear if-else statements.

Apply this diff to simplify the code:

boolean hasJobs = numberOfCurrentBuildJobs > 0;
-BuildAgentInformation.BuildAgentStatus status = isPaused ? BuildAgentInformation.BuildAgentStatus.PAUSED
-        : hasJobs ? BuildAgentInformation.BuildAgentStatus.ACTIVE : BuildAgentInformation.BuildAgentStatus.IDLE;
+BuildAgentInformation.BuildAgentStatus status;
+if (isPaused) {
+    status = BuildAgentInformation.BuildAgentStatus.PAUSED;
+} else if (hasJobs) {
+    status = BuildAgentInformation.BuildAgentStatus.ACTIVE;
+} else {
+    status = BuildAgentInformation.BuildAgentStatus.IDLE;
+}

This change enhances clarity and maintainability by making the logic more explicit.

Likely invalid or redundant comment.


421-423: Restore interrupt status after catching InterruptedException

In the catch block for InterruptedException, it's recommended to restore the thread's interrupt status by calling Thread.currentThread().interrupt();. This ensures that higher-level interrupt handlers are aware of the interruption.

Apply this diff:

catch (InterruptedException e) {
    log.error("Error while pausing build agent", e);
+   Thread.currentThread().interrupt();
}

Likely invalid or redundant comment.

🧹 Outside diff range and nitpick comments (4)
src/main/java/de/tum/cit/aet/artemis/buildagent/service/SharedQueueProcessingService.java (4)

Line range hint 76-119: New class variables support pause/resume functionality

The added variables appropriately support the new pause/resume functionality and scheduled task execution. The use of AtomicBoolean for flags ensures thread-safety, which is crucial in a concurrent environment.

Consider adding documentation for the pauseGracePeriodSeconds configuration property in the application's configuration files (e.g., application.yml or application.properties):

artemis:
  continuous-integration:
    pause-grace-period-seconds: 15  # Grace period in seconds before forcefully cancelling running build jobs when pausing the build agent

139-165: Initialization of scheduled task and message listeners

The initialization of the scheduled task and setup of message listeners for pause/resume topics are well-implemented. This allows for distributed control of the build agent's state.

Consider adding error handling for the addMessageListener calls to gracefully handle potential exceptions:

try {
    pauseBuildAgentTopic.addMessageListener(message -> {
        if (message.getMessageObject().equals(hazelcastInstance.getCluster().getLocalMember().getAddress().toString())) {
            pauseBuildAgent();
        }
    });
} catch (Exception e) {
    log.error("Failed to add listener to pauseBuildAgentTopic", e);
}

// Similar try-catch for resumeBuildAgentTopic

Line range hint 306-327: Simplify build agent status determination

The logic for determining the build agent status is correct, but it can be simplified for better readability.

Consider refactoring the status determination as follows:

BuildAgentInformation.BuildAgentStatus status;
if (isPaused.get()) {
    status = BuildAgentInformation.BuildAgentStatus.PAUSED;
} else if (numberOfCurrentBuildJobs > 0) {
    status = BuildAgentInformation.BuildAgentStatus.ACTIVE;
} else {
    status = BuildAgentInformation.BuildAgentStatus.IDLE;
}

This approach makes the status determination more explicit and easier to understand at a glance.


430-473: Well-implemented pauseBuildAgent method

The pauseBuildAgent method is well-structured and handles various scenarios effectively. The use of CompletableFuture for waiting on running jobs is a good approach, providing both timeout capabilities and proper cancellation.

Improve the interrupt handling in the catch block:

catch (InterruptedException e) {
    Thread.currentThread().interrupt(); // Restore the interrupt status
    log.error("Interrupted while waiting for running build jobs to finish", e);
} catch (ExecutionException e) {
    log.error("Error while waiting for running build jobs to finish", e);
}

This ensures that the interrupt status is properly maintained, allowing higher-level interrupt handlers to function correctly.

🔇 Additional comments (6)
src/main/java/de/tum/cit/aet/artemis/buildagent/service/SharedQueueProcessingService.java (6)

Line range hint 5-21: New imports support enhanced functionality

The added imports are appropriate for the new features implemented in this class. They support scheduling tasks, handling timeouts, and ensuring thread-safe operations with AtomicBoolean.


120-127: Constructor updated to include TaskScheduler

The addition of the TaskScheduler parameter to the constructor is appropriate and consistent with the existing dependency injection pattern. This change supports the new scheduled task functionality introduced in the class.


169-182: Improved cleanup in removeListenerAndCancelScheduledFuture

The renaming of the method and the addition of scheduled future cancellation improve the cleanup process. This ensures that no unnecessary tasks continue running after the service is shut down.


223-230: Improved efficiency in checkAvailabilityAndProcessNextBuild

The addition of checks for queue emptiness and paused state before acquiring the lock improves the efficiency of this method. This prevents unnecessary lock acquisition and processing when the queue is empty or the agent is paused.


491-512: Well-implemented resumeBuildAgent method

The resumeBuildAgent method is well-structured and covers all necessary steps for resuming the build agent. The use of pauseResumeLock ensures thread safety, and the order of operations (removing old listeners/tasks before adding new ones) is correct. This implementation effectively restores the build agent to its running state.


Line range hint 1-539: Overall assessment of SharedQueueProcessingService changes

The modifications to the SharedQueueProcessingService class successfully implement the pause/resume functionality for the build agent. The changes are well-structured, maintain thread safety through proper use of locks and atomic operations, and effectively handle various scenarios such as graceful shutdown of running jobs during pause.

Key improvements include:

  1. Addition of pause/resume methods with proper synchronization.
  2. Integration of scheduled tasks for periodic checking of build jobs.
  3. Implementation of message listeners for distributed control of the build agent's state.
  4. Modification of existing methods to respect the paused state.

While the overall implementation is solid, there are a few areas where minor improvements could be made:

  1. Simplifying the build agent status determination logic for better readability.
  2. Extracting duplicated result processing logic into a separate method.
  3. Enhancing error handling for message listener setup.
  4. Ensuring consistent thread safety in the handleTimeoutAndCancelRunningJobs method.

These changes significantly enhance the flexibility and control of the build agent, allowing for better management of resources and graceful handling of maintenance scenarios.
