Examples with FlowGraphWalker org.jenkinsci.plugins.workflow.graph.FlowGraphWalker used on opensource projects

Example 1 with FlowGraphWalker

use of org.jenkinsci.plugins.workflow.graph.FlowGraphWalker in project workflow-cps-plugin by jenkinsci.

the class CpsScriptTest method dumpError.

/**
 * Picks up any errors recorded in {@link #exec}.
 */
private String dumpError() {
    StringBuilder msg = new StringBuilder();
    FlowGraphWalker walker = new FlowGraphWalker(exec);
    for (FlowNode n : walker) {

        if (e != null) {
            msg.append(Functions.printThrowable(e.getError()));
        }
    }
    return msg.toString();
}

Example 2 with FlowGraphWalker

use of org.jenkinsci.plugins.workflow.graph.FlowGraphWalker in project workflow-cps-plugin by jenkinsci.

the class CpsBodyExecutionTest method synchronousExceptionInBody.

/**
 * When the body of a step is synchronous and explodes, the failure should be recorded and the pipeline job
 * should move on.
 *
 * But instead, this hangs because CpsBodyExecution has a bug in how it handles this case.
 * It tries to launch the body (in this case the 'bodyBlock' method) in a separate CPS thread,
 * and puts the parent CPS thread on hold. Yet when the child CPS thread ends with an exception,
 * it fails to record this result correctly, and it gets into the eternal sleep in which
 * the parent CPS thread expects to be notified of the outcome of the child CPS thread, which
 * never arrives.
