Not timing out when launch pid fails to appear

XMLWordPrintable

      ShellController.exitStatus if more than a minute has elapsed since doLaunch, and still _pid == 0, return -2

      Also consider uncommenting ps.stdout(listener) under some conditions.

          [JENKINS-28400] Not timing out when launch pid fails to appear

          Oleg Nenashev added a comment - - edited

          We got into such issue in JENKINS-28821. The build may hang infinitely, because durable-task's callback may be unable able to write pidfile and other metadata from the docker run. In such case the server side will never get a termination event.

          Sample code:

          // The temporary variable is to ensure JENKINS_SERVER_COOKIE=durable-… does not appear even in argv[], lest it be confused with the environment.
        String cmd = String.format("echo $$ > '%s'; jsc=%s; %s=$jsc '%s' > '%s' 2>&1; echo $? > '%s'",
                c.pidFile(ws),
                cookieValue,
                cookieVariable,
                shf,
                c.getLogFile(ws),
                c.getResultFile(ws)
                )./* escape against EnvVars jobEnv in LocalLauncher.launch */replace("$", "$$");

          The script is error-prone. If it is not being launched, Durable task thinks the task thinks the task is running => we need an additional flag as a workaround
