Read Structure from another thread Edited

[Alexander Raymukanov]

I prepare listener of rank change event with scriptrunner. I change rank from Structure by drag&drop of rows, structure is sorted by rank.

When I read structure in main thread in listener and get data, then I see that sequence of rows is old. If then I run the same script from console then sequence of rows is new.

Now I think script from listener executes before rebuild of structure in main thread. But if I try to make new thread, make sleep and then try to read structure I get nothing.

Please help. I am not sure that I work in new thread in right way.

In  atlassan-jira.log there is no log entry for line "log.info "Structures - "+structures+"\n"'

Code

import com.almworks.jira.structure.api.StructureComponents
import com.almworks.jira.structure.api.permissions.PermissionLevel
import com.onresolve.scriptrunner.runner.customisers.PluginModule
import com.onresolve.scriptrunner.runner.customisers.WithPlugin
import org.apache.log4j.*;
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.util.thread.JiraThreadLocalUtil

Thread.start{
    def jtlu = ComponentAccessor.getComponent(JiraThreadLocalUtil)
    jtlu.preCall()
    try {

        @WithPlugin("com.almworks.jira.structure")
        @PluginModule

        StructureComponents structureComponents


        IssueManager issueManager = ComponentAccessor.getIssueManager()

        MutableIssue issue = issueManager.getIssueObject(event.getIssueId())

        log.setLevel(Level.ALL)
        log.info "Start\n"
        log.debug("New thread start")
        Thread.sleep(1000)
        log.debug("New thread start2")


        def String structureName="Test"


        def structures = structureComponents.getStructureManager().getStructuresByName(structureName, PermissionLevel.VIEW);
        log.info "Structures - "+structures+"\n"
        def long structureId;




        log.info "new structure finished in new thread\n"
    }

    finally {
        jtlu.postCall(log)
    }

}
Thread.sleep(3000)

  If I move block below out of new thread block, than structures is empty

@WithPlugin("com.almworks.jira.structure")
@PluginModule

StructureComponents structureComponents

I've answered this question in our ServiceDesk, let me publish the answer here as well:

The reason for such behavior is that StructureManager.getStructuresByName returns a list of structures accessible to the current user at some permission level. The current user is kept in a thread-local variable. As the current user is not specified, the list is empty.

To find a user:

import com.atlassian.jira.user.util.UserManager

@PluginModule
UserManager userManager

def user = userManager.getUserByKey("admin")

To execute code under a user authority:

def structures = StructureAuth.sudo(user, false, { structureComponents.getStructureManager().getStructuresByName(structureName, PermissionLevel.VIEW) });
