This release is past End of Life.

Release 6.1.8 is a minor bug fix release.

Bug Fixes (6)

Command-line Tools (1)

• tungsten_post_process now handles whitespace properly on property= lines in INI files.
  Issue: CT-1364

Core Replicator (2)

• In MySQL releases using old row events format (MySQL 5.6 or earlier), Delete_rows_v1were badly handled, leading to an extraction error when handling such an event type.
  Issue: CT-1358
• Fixes an issue that would prevent a service from going offline at a specified time (trepctl online -until-time) or at a specific seqno (trepctl online -until-seqno) when parallel apply is enabled.
  Issue: CT-1243

Manager (3)

• Fixes a memory leak when unrecognized connections to manager port 11999 were made.
  Issue: CT-1357
• A network partition between primary and relay sites with port 11999 still functioning was leading to full connectivity outage. Managers now send data services configuration with every node update (one per node every 3s) so that connectors remain up-to-date even in that corner case.
  Issue: CT-1356
• Managers now accept both unencrypted and TLS connections from connectors. This allows migrations when security is enabled from earlier versions to 6.1.2+, as well as seamless switch to encrypted connector-manager communications.

  Important

  When upgrading to this release from an earlier release, and SSL is either already enabled, or being enabled as part of the upgrade, it is important that managers are upgraded **before** the connectors.

  Note that non-secured connectors connections will trigger a warning in the manager logs:

  WARN [RouterGatewayServer] - Un-encrypted connection request from <connector address> while this manager 
  is configured to use SSL. This is expected ONLY when migrating manager<>connector communication to SSL. 
  Otherwise it might be a misconfiguration of this connector.

  Issue: CT-1320
