Title: Message Title

Alexander Komarov created an issue   Jenkins / JENKINS-53315 Timeout step should support a closure to execute prior to killing body Issue Type: Improvement Assignee: Unassigned Components: workflow-basic-steps-plugin Created: 2018-08-29 12:01 Priority: Minor Reporter: Alexander Komarov Currently, the timeout step simply kills whatever processes were launched during execution of its body, and then throws an exception.  This makes it difficult to perform any automated debugging on these processes, since they are killed by the time the user finds out that they are hung (or slow).  You can argue that this should be done outside of Jenkins, but, too often, Jenkins is the only place this is visible due to frequency of execution or differences in the environment. Currently:   try {   timeout(time: 1, unit: 'HOURS') {      sh "java IntermittentlySlowProcess"   } } catch (t) {     //It's too late to, for example, send a "kill -3" to the slow/hung java process }   What I'd propose (and I'm willing to try to make a PR if this seems reasonable):   timeout(time: 1, unit: 'HOURS', beforeKill: {    sh "killall -3 java" //for example }) {    sh "java IntermittentlySlowProcess" }     "beforeKill" can be used for clean shutdown of complex tasks, analysis of problems, etc. Thoughts welcome.
