Bumps org.agrona:agrona from 1.21.1 to 2.3.0.

Release notes

Sourced from org.agrona:agrona's releases.

2.3.0

• [Breaking] Changed org.agrona.concurrent.ShutdownSignalBarrier to use shutdown hooks instead of signals.

  Previously ShutdownSignalBarrier relied on intercepting SIGINT and SIGTERM OS signals by overriding JVM's signal handling which was preventing shutdown hooks from be executed. This in turn was breaking applications and frameworks that relied on shutdown hooks for clean termination.

  New implementation uses shutdown hooks instead and requires ShutdownSignalBarrier to be explicitly closed.

  NB: Failure to close ShutdownSignalBarrier might result in JVM not terminating!

  As the result the code using ShutdownSignalBarrier needs to be updated:

  • Old:

  class UsageSample
  {
      public static void main(final String[] args) 
      {
          try (MyService service = new MyService())
          {
              new ShutdownSignalBarrier().await();
          }
      }
  }

  • New:

  class UsageSample
  { 
      public static void main(final String[] args) 
      {
          try (ShutdownSignalBarrier barrier = new ShutdownSignalBarrier();
               MyService service = new MyService())
          {
              barrier.await();
          }
      }
  }

  In the above example ShutdownSignalBarrier is closed last to ensure that service terminates completely before ShutdownSignalBarrier closes which in turn allows JVM to exit.

• [Breaking] Deprecated org.agrona.concurrent.SigInt for removal. Use org.agrona.concurrent.ShutdownSignalBarrier instead.

  NB: org.agrona.concurrent.SigInt.register(java.lang.Runnable) is unsafe as it overrides SIGINT signal handling of the JVM thus preventing shutdown hooks from being executed.

  An example using ShutdownSignalBarrier instead of SigInt:
