WANdisco SVN MultiSite Plus Release: 1.6.5 Build:34381

Date: 19 January 2017

Fixes

Fixed a bug where in certain circumstances latency and packet loss can cause agreement hangs. (NV-3799)

Fixed a bug where adding a new node as "Voter only" would cause a panic requiring node removal/re-install. (NV-5902)
Repositories are now never removed by MSP, they are simply removed from replication. Customers will need to manually cleanup repository data left on disk if desired. (NV-5944)
Fixed a bug where SVN wildcard AuthZ would sometimes cause inappropriate permission denied. (NV-5962)
Fixed a bug where the "Reload" button would not work after repository repair. (NV-5966)

MSP now ships with a tool that enables post-installation implementation of SSL (svn-ms-replicator-cryptPassword.jar). (NV-6085)

Known Issues

Logging changes in MSP 1.6.5 will cause customized logging settings of the log4j.properties file to be lost during upgrade, and a new log4j.properties file will be created. The original file will remain in place in the properties directory but will have a time stamp appended to the file name. Any prior edits in this file should be reviewed and if applicable, updates made to the new file. (NV-6148)
When setting logging entries, the cache needs to be flushed manually for changs to be seen. (NV-6141)
MSP 1.6.5 cannot be upgraded to MSP 1.9.0, MSP 1.9.1 or MSP 1.9.2. It must be upgraded to either MSP 1.6.6 or MSP 1.9.3 (or above). (NV-6152)
During the UI installation process, if uploading an existing users.properties file please ignore the Invalid file type message if the alert Successfully uploaded users.properties is present in the top right hand corner. (NV-5647)
After an IP change the restart of a node can sometimes be significantly delayed. To avoid this the node can be manually restarted. (NV-6108)
If EMR is used to remove a node you may be left with a pending task of type tasksTypeREMOVE_STATE_MACHINE_TASK, if this is the case then: (NV-6050)
1. Cancel the active/pending task (type is tasksTypeREMOVE_STATE_MACHINE_TASK)
2. Restart the node where the pending task existed.

WANdisco SVN MultiSite Plus Release: 1.6 Build: 32467

Date: 25 August 2015

New Features

This version of SVN MultiSite Plus is bundled with SVN 1.8.13. (NV-4947)

The logs now qualify whether a repository is sent offline automatically or through admin intervention. (NV-3283)
Fixed an issue where entering an error in the induction IP address field would prevent the induction from completing, even after correcting the error. (NV-4078)
We now filter warnings which occur when proposals are rejected because they have already been actioned. These warnings would occur in rare situations when changes are made to the replication changes at the same time, resulting in one set of changes being accepted and one set failing. (NV-4141)
No longer possible to start a consistency check on a repository that no longer exists. (NV-4273)
Fixed an issue where running a consistency check when there's no quorum would result in misleading results. Now running a consistency check without quorum will result in an appropriate warning. (NV-4275)

Fixed an issue where email notifications of an out of local repository disk space event are not triggered. (NV-4532)
Fixed issue where replicator would fail to start and generate a PANIC java.lang.AssertionError. (NV-4573)
Fixed an issue that could occur when changing memberships after the loss of a node. The resulting state could result in an endless cycle of restarts due to failing an assertion. (NV-4582)
The installer now better handles upgrades where Flume is not installed for handling auditing. The interactive installer now prompts for requirements instead of throwing an error. (NV-4599)
Fixed an issue that could in very rare circumstances result in an NPE during the induction of new nodes. (NV-4872)
Completed additional optimization to improve general performance of the admin UI. (NV-4809)
Email template now includes trigger and template for sending warnings about approaching expiration of product license. (NV-4840)

Increased Java heap for when Flume is installed. (NV-4918)
When deploying Flume for auditing: Fixed a conflict between competing "flume" service names. (NV-4932)
WANdisco's underlying DConE replication system includes a number of fixes for edge case problems. (NV-4923)
Permission errors on a repository now result in appropriate logging errors. Previously it was possible that a failure to complete a check on a repository would result in the test passing instead of being reported as incomplete. (NV-4936)
The repository repair system now permits for a retry of the initial helper process where all repositories are brought to a stop. (NV-4939)
Corrected attribution of automatic actions in logs. Previously some actions where appeared to have been done manually by an administrator when in fact they were automated actions kicked off indirectly by administrator actions. (NV-4978)
Removed stray newline characters "" from email message templates. (NV-5040)
Unintended white spaces pasted into the data fields in the induction process no longer causes the induction to get stuck in pending. This issue was seen when testing in the Firefox browser, where using its native double-click to select feature would add a hidden tab character to the selected text. (NV-5048)
Improved handling of node locations on world map on the Nodes page, now allowing for locations that fell outside a previously set of latitude and longitude limits. (NV-5077)
Fixed error in handling flume installation that resulted in incorrect error messaging and could report a failed installation as successful. (NV-5083)
Admin UI "growl" message now correctly appears if an attempt is made to remove a node from outside its replication group. (NV-5087)
Installing SVN MultiSite Plus with Flume no longer fails if Access Control and Flume have already been installed. (NV-5102)

Fixed an issue where a replication group could appear ready, even if it was still pending if the node on which it was created was restarted. (NV-5132)
Incorrect error message no longer shows in the admin UI when trying to add a new repository to a replication group that has not yet been completed. (NV-5133)
We now verify that there isn't an ongoing bulk consistency check before allowing another to start. (NV-5144)

Known Issues

Changes to some SVN elements that come with version1.6 may invalidate data that is currently cached by either Apache or svnserve. For this reason, you should shutdown Apache and svnserve on all nodes before starting an installation or upgrade to version 1.6. Don't forget to restart the service once all nodes have been installed/upgraded. (NV-5256)
There is a minor issue with the 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)
There's currently an issue with installing SVN MultiSite Plus into an existing directory using the tar-based installer. If you set the installation path to be the same as a previous installation then the installer will fail with a message like:
```
Install Error: Packaging directory is aldeady present at /opt/myInstall please remove before reinstalling.
```
It's possible to work around this issue by installing SVN MultiSite Plus with the mounted file system unmounted. Then shut it down, move it out of the way (rename the install directory), create the mount-over directory, mount the file system, tar-pipe-copy the installed software from the renamed directory into the mounted directory.

It's currently not possible to set up SSL encryption using different passwords for the key and keystore. If different passwords are used, you will see a PANIC error log like the following:

2015-02-12 16:25:39 ERROR [PanicHandler:handle] - main:[PANIC:
java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext)

(NV-5197)

WANdisco SVN MultiSite Plus Release: 1.5 Build: 1964

Date: 1 July 2015

Fixes

Fixed slow Content Delivery that could occur with a specific set of network conditions. (NV-4909)

Known Issues

Currently, you need to ensure that the Number of Revisions in Default Consistency Check are the same on all nodes before starting a check. This is important if you have edited the value in production and then add a new node, which will use the default value unless it is edited to match.

WANdisco SVN MultiSite Plus Release: 1.5 Build: 1845

Date: 21 May 2015

Fixes

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)
We've made improvements to the upgrade process to reduce the time that it can take to upgrade SVN MultiSite nodes on deployments with large numbers of nodes. (NV-4723)

You can now disable schedule from Replication Groups tab. (NV-4812)

Known issues

Default start and kill priorities are incorrect in SUSE 11. (DE562)
If you try to do an EMR on a node but everything still has quorum, then no nodes are reconfigured. The system then expects an EMR report from all nodes even though there is one node down, the one you want to remove. Do not use EMR in this situation. (NV-4700)
MSP installer exits with error when replacing existing SVN binaries. (NV-4755)
Consistency Check via UI does not return results for all nodes in the RG on the repository info page. (NV-4428)

Known Issues

When setting a repository to Global Read-only a message will appear through the UI that warns that the operation failed. Currently this message is appearing when the operation is actually successful. (NV-4549)

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)
