[JIRA] [core] (JENKINS-18169) Deadlock when running multiple delete

Mon, 03 Jun 2013 00:00:48 -0700

Issue Type: Bug Bug
Affects Versions: current
Assignee: Unassigned
Components: core
Created: 03/Jun/13 6:58 AM
Description:

Tried to remove ~20 builds in parallel with 30 days of build logs (a lot of files) and this resulted in a deadlock and we needed to restart the server.
JavaMelody listed the doDelete threads as deadlocked and showed
1 x hudson.model.Job.delete(Job.java:587)
17 x hudson.model.Project.getPublishersList(Project.java:114)
as a result of the deadlock we can't edit builds anymore

/configSubmit : http-bio-8080-exec-3552	yes	5	BLOCKED	hudson.model.Project.getPublishersList(Project.java:114)

/doDelete : http-bio-8080-exec-3503	yes	5	BLOCKED	hudson.model.Project.getPublishersList(Project.java:114)

/doDelete : http-bio-8080-exec-3543	yes	5	BLOCKED	hudson.model.Job.delete(Job.java:587)

Looking in project.java it looks like a deprecated method is used

/**
 * @deprecated as of 1.463 We will be soon removing the restriction that
 *             only one instance of publisher is allowed per type. Use
 *             {@link #getPublishersList()} instead.
 */
public Map<Descriptor<Publisher>,Publisher> getPublishers() {
return publishers.toMap();
}
