the class CommitLogFailurePolicyTest method testCommitFailurePolicy_ignore_beforeStartup.

@Test
public void testCommitFailurePolicy_ignore_beforeStartup() {

Example 3 with KillerForTests

use of org.apache.cassandra.utils.KillerForTests in project cassandra by apache.

the class CommitLogTest method beforeClass.

@BeforeClass
public static void beforeClass() throws ConfigurationException {
    // Disable durable writes for system keyspaces to prevent system mutations, e.g. sstable_activity,
    // to end up in CL segments and cause unexpected results in this test wrt counting CL segments,

    CompactionManager.instance.disableAutoCompaction();
    testKiller = new KillerForTests();
    // While we don't want the JVM to be nuked from under us on a test failure, we DO want some indication of
    // an error. If we hit a "Kill the JVM" condition while working with the CL when we don't expect it, an aggressive
    // KillerForTests will assertion out on us.
    oldKiller = JVMStabilityInspector.replaceKiller(testKiller);
}

Example 4 with KillerForTests

use of org.apache.cassandra.utils.KillerForTests in project cassandra by apache.

}

Example 5 with KillerForTests

the class CommitLogFailurePolicyTest method testCommitFailurePolicy_ignore_afterStartup.

@Test
public void testCommitFailurePolicy_ignore_afterStartup() throws Exception {

    //startup must be completed, otherwise commit log failure must kill JVM regardless of failure policy
    daemon.completeSetup();

        CommitLog.handleCommitError("Testing ignore policy", new Throwable());
        //error policy is set to IGNORE, so JVM must not be killed if error ocurs after startup
