hudson.Launcher:ProcStarter::envs() may throw NPE

    XMLWordPrintable

Details

    Description

      ProcStarter::envs() calls envs.clone(), but does not check envs variable for null. BTW, the variable may be null in the following case (see JENKINS-19506):

      • There are several wrappers
      • One of wrappers triggers remote call (Launcher::launch()) in setUp() or decorateLauncher() methods to setup variables (example: android-emulator) => it will make all other launchers to provide their environment variables
      • One of other wrappers retrieves ProcStarter.envs() in setUp() or decorateLauncher()
      • envs are empty for nested call => execution of other wrapper causes NPE inside core

            Is this serious and safe enough for LTS inclusion?

            The functional change: https://github.com/jenkinsci/jenkins/commit/ef943a3ee69529a9f41353f134043ed3363f12e0
            It's definitely safe

            [FIXED JENKINS-20559] - ProcStarter: Check for null before cloning of environment variables list

            Resolves https://issues.jenkins-ci.org/browse/JENKINS-20559
            BTW, I also need to add some tests to "Test Harness" in order to improve coverage of nested operations.
            These test require a fix for https://issues.jenkins-ci.org/browse/JENKINS-19454
