Help reg my Scriptrunner class

Aisha M

I have created a public class in Script editor for processing project keys. I have a Service desk form which will supply the project keys from the form to this class thro the post function, which is supposed to be processed later by a different script.

The keys are getting supplied correctly but is not retained in the class for processing by another script. What am i missing for the keys to be retained for processing later ?


public class ProjectUpdater {
private static final Logger log = Logger.getLogger(ProjectUpdater.class)
public static ConcurrentHashMap<String, String> projectDetailsMap = new ConcurrentHashMap<>()
public static void updateProjects(List<String> projectKeys)

Hi @Aisha M

All is good, thanks! I hope you're doing great as well.

This approach might not be the best that I'd suggest. First, in a clustered setup (I assume you have multiple nodes in your Jira DC), each node has its own JVM, and static variables are not shared across nodes. This means that the ConcurrentHashMap in your class will only be available on the node where it was set, and other nodes won't have access to it. So the access to this class from other requests might be handled by the other instances which means that they will have their own ConcurrentHashMap.

On the other hand, static variables which are accessed in a concurrent environment should be handled correctly. Ensure that the static projectDetailsMap is being accessed and modified in a thread-safe manner, I mean, while you are adding to this map, another thread might be clearing it.

I don't know your case 100% but have you considered storing these keys in a more permanent storage mechanism, such as a database? In this way, you can share this data across different scripts easier.

I hope I was clear and this helps!

@Tuncay Senturk _Snapbytes_ Thank you so much for your insights !! I actually wanted to directly use the customfield which takes the project keys as input from the form in to the script.

But, our org wants to use the class instead, so that the method can be re-used for multiple scripts.

For now (for testing purpose) have two scripts on the service desk post function ,

1) one to supply the project keys to the class

2) to get the processed project keys from the class and post the keys as comment on the issue (this i randomly added to test if the class is working)

From my understanding, these individual scripts could be invoked via post-functions from separate nodes. As I mentioned, each node has its own JVM. This means that a static map in the class will not be helpful because each node will have its own map. If you add a key to the map in node A, it won't be visible in node B. To address this, you can use Atlassian cache to distribute this map to other nodes. Or you can use custom field as you mentioned

I took your feedback, and simplified the class script. Now I'm able to get the project keys from the service desk form to the class, and then get the projects list from the class to be added as a comment on the issue when resolved.

But our actual requirement is something LIKE THIS -> .Basically, we want to have users submit a Service desk from with the project keys, This project keys will be processed by the class, and will later be utilized by another script (another developer is working on) which will migrate these projects to a new workflow scheme.

For my testing purpose, I added the comment part to check if the projects keys are getting processed by the class.

Do, you think I'm on the right track with this ? I kinda feel overwhelmed at this point. . Not lol

CLASS SCRIPT:

public class ProjectUpdater {

    private static final Logger log = Logger.getLogger(ProjectUpdater.class)

    public static void updateProjects(List<String> projectKeys) 

    {

        log.info("Starting updateProjects with keys: ${projectKeys}")

        projectKeys.each { projectKey ->

        log.info("Processing project key: ${projectKey}")

            def project = ComponentAccessor.getProjectManager().getProjectByCurrentKey(projectKey)       

            if (project) {

                log.info("Project found: ${project.name}")

            } else {

                log.info("Project not found: ${project.Key}")

            }

        }

        log.info("Completed updateProjects.")

    }

}
