4-8: LGTM!The new
BuildAgentStatusenum 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 thestatusproperty type change.Updating the
statusproperty to use theBuildAgentStatusenum aligns with the introduction of the new enum. However, ensure that all references to thestatusproperty throughout the codebase are updated to handle the new enum type instead of a boolean.Run the following script to verify the
statusproperty usage:Verification successful
Verification successful: Status property change implemented correctly
The change from a boolean to the
BuildAgentStatusenum for thestatusproperty 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.Scripts executed

src/main/webapp/i18n/en/buildAgents.json (4)
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
BuildAgentStatusenum 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 statesACTIVE,IDLE, andPAUSEDclearly 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 ofBuildAgentInformationin the codebase.The change in the
statusfield type frombooleantoBuildAgentStatusenum 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
BuildAgentInformationin the codebase have been updated to accommodate the newstatusfield type.Run the following script to verify the usage of
BuildAgentInformation:Verification successful
Verification successful: BuildAgentStatus enum properly implemented and used.
The change from
booleantoBuildAgentStatusenum in theBuildAgentInformationrecord has been successfully implemented across the codebase. Key points:
- The
BuildAgentStatusenum 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
AlertServiceandAlertTypeare likely used for displaying alerts related to the new pause and resume functionality.
32-33: LGTM!The
faPauseandfaPlayicons 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
AlertServiceis injected into the constructor and is likely used for displaying alerts related to the new pause and resume functionality.
112-159: LGTM!The
pauseBuildAgent()andresumeBuildAgent()methods follow a similar structure and logic:
- They check if
buildAgent.nameexists before calling the respective service methods.- They use the
subscribemethod to handle the service call results, which is consistent with the existing code.- They use the
AlertServiceto display success, error, and warning alerts based on the service call results and the presence ofbuildAgent.name.- The alert messages are localized using keys from the
artemisApp.buildAgents.alertsnamespace, 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
@switchstatement is a great improvement over the previous@ifstatement. 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 thejhiTranslatedirective, which is a good practice for internationalization.The code segment follows the coding guidelines by using the new
@switchsyntax.src/test/javascript/spec/component/localci/build-agents/build-agent-summary.component.spec.ts (2)
13-13: LGTM!The updated import statement for
BuildAgentto includeBuildAgentStatusis correct and enhances the semantic clarity of thestatusproperty.
127-127: LGTM!The changes to the
statusproperty of theBuildAgentinstances from a boolean value to theBuildAgentStatus.ACTIVEenumeration 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
pauseBuildAgentmethod follows the REST conventions and adheres to the coding guidelines. It correctly uses the@EnforceAdminannotation to restrict access to admin users only. The method delegates the actual pause operation to thelocalCIBuildJobQueueService, maintaining a clean separation of concerns. The logging statement helps with debugging and monitoring. Overall, the implementation looks good.
236-242: LGTM!The
resumeBuildAgentmethod is implemented correctly, following the same pattern as thepauseBuildAgentmethod. It adheres to the REST conventions, coding guidelines, and the principle of least privilege. The method delegates the resume operation to thelocalCIBuildJobQueueService, 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
throwErrorfromrxjsis necessary for mocking error scenarios in the new test cases.
10-10: LGTM!The imports of
MockComponentandMockPipefromng-mocksare necessary for mocking components and pipes in the test suite.
12-12: LGTM!The imports of
BuildAgentandBuildAgentStatusfromapp/entities/programming/build-agent.modelare necessary for using these types in the test suite.
19-19: LGTM!The imports of
AlertServiceandAlertTypefromapp/core/util/alert.serviceare necessary for using these in the new test cases.
34-35: LGTM!The addition of
pauseBuildAgentandresumeBuildAgentmethods to themockBuildAgentsServiceis 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
statusproperty of themockBuildAgenttoBuildAgentStatus.ACTIVEis necessary to align with the newBuildAgentStatusenum introduced in theBuildAgentmodel. UsingBuildAgentStatus.ACTIVEis the correct value for an active build agent.
123-125: LGTM!Declaring the
alertServiceandalertServiceAddAlertStubvariables is necessary for injecting and spying on theAlertServicein 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 ofAlertServicein the test suite.
143-144: LGTM!Injecting
AlertServiceand setting up a jest spy on itsaddAlertmethod 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!

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
@PostConstructannotation.
144-150: LGTM!The
pauseBuildAgentandresumeBuildAgentmethods 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
whenCompletecallback to remove the build job ID from therunningFuturesmap 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
getRunningBuildJobIdsmethod 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 therunningFuturesmap usingSet.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
cancelBuildJobmethod 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@switchfor rendering the build agent status!The code segment correctly uses the
@switchdirective to conditionally render the status based on thevaluevariable. The cases cover all possible status values, and the status messages are properly translated.
43-52: Duplicate code segmentThis code segment is identical to the one reviewed earlier at line range 43-52. Skipping the review to avoid redundancy.

89-91: LGTM!The
hazelcastInstancefield is properly autowired and qualified. The use ofHazelcastInstanceis appropriate for interacting with Hazelcast in the tests.
483-502: LGTM!The
testPauseAndResumeBuildAgentmethod 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 correctlyThe 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 addedThe 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 maintainedThe new entries have been integrated seamlessly into the existing file structure. The JSON remains valid, and the formatting is consistent throughout the file.

15-15: LGTM: Correct translation for "paused" statusThe translation "Angehalten" for "paused" is accurate and consistent with the existing style for status translations.
19-25: LGTM: Correct and consistent translations for alertsThe 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" actionThe translation "Anhalten" for "pause" is accurate and consistent with the related "paused" status translation.
27-27: LGTM: Correct translation for "resume" actionThe 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.

97-100: Thread safety ensured withvolatilevariablesGreat job declaring
isPausedandprocessResultsasvolatile. This ensures that changes to these variables are immediately visible to all threads, preventing potential data races.
192-199: Properly checkingisPausedbefore processing build jobsThe added checks for
isPausedbefore processing build jobs incheckAvailabilityAndProcessNextBuild()prevent the agent from processing jobs while paused, which helps avoid race conditions.
275-277: Simplify build agent status determination for readabilityConsider 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 catchingInterruptedExceptionIn the catch block for
InterruptedException, it's recommended to restore the thread's interrupt status by callingThread.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.

76-119: New class variables support pause/resume functionalityThe 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
pauseGracePeriodSecondsconfiguration property in the application's configuration files (e.g.,application.ymlorapplication.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 listenersThe 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
addMessageListenercalls 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 determinationThe 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 methodThe
pauseBuildAgentmethod is well-structured and handles various scenarios effectively. The use ofCompletableFuturefor 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.

5-21: New imports support enhanced functionalityThe 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 TaskSchedulerThe 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 removeListenerAndCancelScheduledFutureThe 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 checkAvailabilityAndProcessNextBuildThe 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 methodThe
resumeBuildAgentmethod is well-structured and covers all necessary steps for resuming the build agent. The use ofpauseResumeLockensures 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 changesThe modifications to the
SharedQueueProcessingServiceclass 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:
- Addition of pause/resume methods with proper synchronization.
- Integration of scheduled tasks for periodic checking of build jobs.
- Implementation of message listeners for distributed control of the build agent's state.
- 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:
- Simplifying the build agent status determination logic for better readability.
- Extracting duplicated result processing logic into a separate method.
- Enhancing error handling for message listener setup.
- Ensuring consistent thread safety in the
handleTimeoutAndCancelRunningJobsmethod.These changes significantly enhance the flexibility and control of the build agent, allowing for better management of resources and graceful handling of maintenance scenarios.

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:
Scenario 1: Build agent with no running jobs
Scenario 2: Build agent processing jobs (shorter than grace period)
Scenario 3: Build agent processing jobs (longer than grace period)
