Class DumpStackTracesTimer

  • All Implemented Interfaces:
    java.lang.Runnable
    public class DumpStackTracesTimer
extends java.util.TimerTask
    Starts a task which will dump stack trace information after some time. Mostly a copy of org.eclipse.test.EclipseTestRunner.startStackDumpTimeoutTimer(). Necessary to know whether and where tests are hanging if a timeout occurred during tests.

      Modifier and Type Field Description
      private static int SECONDS_BEFORE_TIMEOUT_BUFFER
      SECONDS_BEFORE_TIMEOUT_BUFFER is the time we allow ourselves to take stack traces delay "SECONDS_BETWEEN_DUMPS", then do it again.
      private static int SECONDS_BETWEEN_DUMPS
      SECONDS_BETWEEN_DUMPS is the time we wait from first to second dump of stack trace.

      • SECONDS_BEFORE_TIMEOUT_BUFFER

        private static final int SECONDS_BEFORE_TIMEOUT_BUFFER
        SECONDS_BEFORE_TIMEOUT_BUFFER is the time we allow ourselves to take stack traces delay "SECONDS_BETWEEN_DUMPS", then do it again. On current build machine, it takes about 30 seconds to do all that, so 2 minutes should be sufficient time allowed for most machines. Though, should increase, say, if we increase the "time between dumps" to a minute or more.

      • SECONDS_BETWEEN_DUMPS

        private static final int SECONDS_BETWEEN_DUMPS
        SECONDS_BETWEEN_DUMPS is the time we wait from first to second dump of stack trace. In most cases, this should suffice to determine if still busy doing something, or, hung, or waiting for user input.
