Integrated code lifecycle: Add timeout when stopping hanging containers in edge cases

[laurenzfb]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I strictly followed the server coding and design guidelines.
• I documented the Java code using JavaDoc style.

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

There is an unresolved issue in LocalCI that prevents unresponsive Docker containers from being stopped / killed. Calling the stopContainerCmd or killContainerCmd may lead to endless execution / hanging of the commands, preventing the succeeding code from being executed. This leads to the build job not being processed properly.

Description

I added timeouts for the stop and kill commands. This does not fix the issue of the unresponsive container not being killed but it allows for the build job to finish processing and thus properly be displayed in the client.

Review Progress

Performance Review

• I (as a reviewer) confirm that the client changes (in particular related to REST calls and UI responsiveness) are implemented with a very good performance
• I (as a reviewer) confirm that the server changes (in particular related to database calls) are implemented with a very good performance

Walkthrough

The recent updates enhance the BuildJobContainerService by introducing asynchronous handling for stopping and killing unresponsive containers using an ExecutorService. This change improves the robustness and responsiveness of the service by incorporating logging and timeout handling. Additionally, the BuildJobManagementService now includes logging statements to track the IDs of running and stopping containers, aiding in better monitoring and debugging.

Changes

File	Change Summary
src/main/java/de/tum/in/www1/artemis/service/connectors/localci/buildagent/BuildJobContainerService.java	Introduced ExecutorService for asynchronous container operations, added logging and timeout handling.
src/main/java/de/tum/in/www1/artemis/service/connectors/localci/buildagent/BuildJobManagementService.java	Added logging statements to track container IDs and log messages when stopping unresponsive containers.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
