WANdisco Git MultiSite Release: 1.6 Build: eba41260

Date: 24 September 2015

Fixes

  • Removed spurious warning from installer during upgrade. (NV-5094)
  • Fixed possible null pointer exception error during replicator startup if an unfinished task is detected. (NV-5141)
  • Fixed Debian packaging. (NV-5146)

  • Fixed possible deadlock during transaction processing. (NV-5291)
  • Fixed an error in the installer that would reset the system umask value. (NV-5300)

WANdisco Git MultiSite Release: 1.6 Build: c4ef8477

Date: 22 July 2015

New

  • Git MultiSite is now bundled with the latest stable version (2.3.1) of Git. (NV-4061)
  • In Git MultiSite 1.6 the functionality for tiebreaker nodes changes slightly. After upgrading from an earlier version of Git MultiSite, if you make a change to a replication group that has an odd number of voter nodes, including a change to the schedule, any tiebreaker nodes will now lose their special tiebreaker designation. Tiebreaker nodes are now only available when there is an even number of nodes, along with the corresponding risk that a vote could be evenly split between voters. Note that this change is not applied after upgrading to Git MultiSite 1.6 but only after you then alter the an applicable replication group. (NV-5069)

Fixes

  • Install will now exit if Flume install directory is not writable. (NV-5102)

  • Fixed a replicator crash when rp-git-update is called with inappropriate arguments. (NV-4891)
  • Fixed an issue in the transform tool which is used to handled database schema changes during product updates. In extreme cases, product upgrades could exhaust the Java Heap. We've now updated the transform tool so that it requires significantly less memory. (NV-4889, NV-4856)

  • Notification now sent when repositories enter or leave Global Read-Only or Local Read-Only state. (NV-4531)

    This error can be ignored, the temp directory is deleted during the upgrade. (NV-5094)
  • There is a minor issue with the Node IP/Host name entry field on the installer's Server Settings screen where the dropdown selector button doesn't appear if the browser window's size is reduced. (NV-5134)

    {node}
    - Node name
    {event.repository.name}
    - applicable repository event, e.g. Deploy Repository Succeeded, Repository now global or local read only.
    {event.originalProposal.repository.name}}
    - Names the relevant repository that corresponds with an event
    {event.resource.filePathString}
    - Passes the path of the resource that a data monitor is watching
    
    More information about email notification. (NV-4471)


Fixed Issues

  • Flush your browser cache If you are reinstalling and using SSL then you should clear your browser cache before you continue. Previous SSL details are stored in the cache and will cause SSL errors if they are not flushed. NV-4269

  • When setting up Apache for use with your Git deployment, ensure that you create the git-http-backend wrapper script. See http://docs.wandisco.com/git/ms/1.5/admin.html#wrapper script NV-4343

  • We now suppress the "ReplicationGroupNotFoundException" exception which made it difficult to add large numbers of repositories through automation scripts (via the API). (NV-4473)

  • We've not dropped support for the JDK 6. If your deployment is still running with this end-of-life version of Java you should contact WANdisco support for advice on upgrading to JDK 7. (NV-4378)

Known Issues

  • The installer currently doesn't check if you want to monitor Apache, sshd logs or input Apache Avro parameters. We'll ensure these are included in the installation in future release. Until then you can manually configure these elements by following the procedure Manual Setup for Audit logging. (NV-4593)
