Fix createSlave for RestartableJenkinsRule

    XMLWordPrintable

Details

    • 1746.v2b_3c5d1983b_e

    Description

      If you use JenkinsRule.createSlave (or createOnlineSlave) from a test based on RestartableJenkinsRule, it seems to work during the first session. But then the whole slave directory gets quietly deleted during the restart.

      Either this deletion should be suppressed, or there should be an alternate method to create a slave that actually survives the restart intact.

      See WorkflowTest.buildShellScriptAcrossRestart and BindingStepTest.cleanupAfterRestart.

            The workaround is to add a DumbSlave manually.

            Could do that, but some of the tests also seem to require use of a JNLP slave, which is rather more complicated to model. Punting for the moment.

            Maybe split slave creation into KillableSlaveRule for example and bind it where required to JenkinsRule?

            I think would suffice to add methods to JenkinsRule.

            Still a problem with JenkinsSessionRule. The issue is that JenkinsSessionRule.tmp survives restarts but JenkinsRule.env.temporaryDirectoryAllocator as used by createTmpDir does not, and createSlave still uses createTmpDir. Options include

            • use some other agent root dir (e.g. inside $JENKINS_HOME)
            • use a TemporaryFolder scoped to JenkinsSessionRule
            • allow JenkinsRule.env to be overridden from JenkinsSessionRule
