Derek Collison 087a28a13e When creating replicated mirrors where the source stream had a very large starting sequence number, the server would use excessive CPU and Memory.
This is due to the mirroring functionality trying to skip messages when it detects a gap. In a replicated stream this puts excessive stress on the raft system.
This step is not needed at all if the mirror stream has no messages, we can simply jump ahead.

Tests

Tests that run on Travis have been split into jobs that run in their own VM in parallel. This reduces the overall running time but also is allowing recycling of a job when we get a flapper as opposed to have to recycle the whole test suite.

JetStream Tests

For JetStream tests, we need to observe a naming convention so that no tests are omitted when running on Travis.

The script runTestsOnTravis.sh will run a given job based on the definition found in ".travis.yml".

As for the naming convention:

  • All JetStream tests name should start with TestJetStream
  • Cluster tests should go into jetstream_cluster_test.go and start with TestJetStreamCluster
  • Super-cluster tests should go into jetstream_super_cluster_test.go and start with TestJetStreamSuperCluster

Not following this convention means that some tests may not be executed on Travis.
