Polarion ALM 19.1 - What's New and Noteworthy

Siemens Theorist Siemens Theorist
Siemens Theorist

The new version of Polarion is available  -  Polarion ALM version 19.1 (Service Release 1).

 

This release introduces a new User Groups feature for easier enterprise-level permissions management. An early access feature in 19.1, enabled via a system configuration property, it lets administrators define entire groups of users that they then revoke or grant permissions to collectively.  More details below.


We've also delivered some significant improvements and enhancements to the following: 

  • Comparison of LiveDoc Documents - Much faster comparison of huge LiveDocs
  • Optimized UI preferences handling - Scalability boost for thousands of users in a cluster

 

All that along with the usual round of fixes and continuous performance optimizations.

Let's jump in and have a closer look.

 

User Groups Management

The new User Group feature greatly simplifies and ensures the consistency of access rights and permission management. With user groups, administrators can now group users based on their business role and associate both global and project roles in different projects to these groups. So when on-boarding a new user to Polarion, administrators only need to associate the user with the group that corresponds to their business role and they’re immediately granted the permissions required for all relevant projects.

Users can be members of multiple User Groups simultaneously, so administrators can temporarily elevate a user's permission level by adding them to an additional Group with more permissions. Existing direct assignments of project roles to individual users is also still supported, so you can combine these two approaches to assign permissions as you see fit.

 

Enabling User Groups management

Although our teams are not yet done with the whole scope of this functionality, we decided to expose it to our administrators, because it brings very substantial benefit to them. In the Polarion 19.1 release, the User Groups Management feature can be enabled on-demand by adding the following property to the polarion.properties file:

com.siemens.polarion.userGroups.enabled = true


The User Groups feature in the current early-access state has a couple of temporary limitations that will be addressed in the next Polarion 19.2 release for even greater administrative control and convenience.

 

  1. Users and Roles can currently only be assigned to a Group manually by editing the XML configuration files in the SVN repository. How to do this is thoroughly described in Polarion's Help.

  2. When a change is done in a Group that results in a change of a user's access rights, the access file synchronization must be done manually by navigating in Administration to User Management > Roles and clicking on the Synchronize SVN Access File button.

  3. In the Users and Roles administration pages, it is currently not possible to tell the source of a user's role assignment— whether it was assigned directly to them, or it was done via a User Group.

 

Document Compare

 

Faster and less resource-intensive Document compare

Comparison of Document changes has been enhanced by additional preprocessing that speeds up the comparison of very big documents. Depending on the size and structure of the Document, the number of Work Items, and the number of changes, the overall time of the compare has been reduced by tens of percent.

Additional benefits of the new algorithm include:

  • A significant reduction in memory consumption because the changes are now chunked into smaller fragments, and only small pieces of the Documents are being compared at a time.
  • Better visualization of changes in complex tables, not only in the LiveDoc compare but also in the Work Items history.

The following table shows the improvement in some of the biggest test Documents used in our regular performance testing.

Improved navigation through Document changes

Navigating through changes in a Document now visualizes the currently selected change with a purple rectangle for easier review. Additionally, changes can be highlighted by a click, so users can jump to any change in the Document, and then use the navigation buttons to browse through the adjacent changes.

Other Enhancements

 

Configurable hiding of duplicate roots in Work Items Tree table

By default, each item is only exposed once in the dependency tree, so the roots of the tree are hidden in case they are also exposed in the lower levels of the tree (see below).

tree_table_default.png

However, in some cases, customers want to show all items that are the result of the query on the top level of the tree, regardless of having the same items exposed in the lower levels of the dependency tree. A new configuration property gives administrators control over the hiding of duplicate roots.

workitems.treeTable.removeDuplicateRoots = false


Setting the configuration property shown above in Administration > Configuration Properties, either on global or project level, disables the removal of duplicate roots as indicated in the screenshot below.

Digital signature for SAML single sign-on AuthnRequests

Our customers hosting Polarion in the cloud require the highest level of security. In order to clearly identify valid requests from a Polarion service provider on the customer's identity provider side, Polarion now supports the signing of the SAML authentication request.
Refer to our Single Sign-On with Polarion guide for detailed information on how to set up the Authentication request signing.

 

Propagation of Work Item delete in TFS connector

The new TFS connector, part of the Polarion core product since Polarion 19, supports the synchronization of Work Item delete operations on the Polarion side. If  "Work Item A" was previously synchronized from TFS to Polarion, and later deleted on the Polarion side, then this deletion will be propagated to TFS if configured to do so.

 

Configuring attachment previews on remote Window machines

The attachment previews functionality of Polarion typically requires generating the previews on a remote Windows machine when the Polarion server is hosted on a Linux machine. New guidance for setting up remote previews has been prepared and tested by our DevOps team. The new configuration no longer uses the legacy WinExe utility, which no longer works on the newest operating systems, but leverages OpenSSH instead.
Refer to our Linux Installation guide for more details about the new recommended configuration.

 

Changes in supported 3rd party dependencies

The recent change in Oracle's licensing of Java required a change in our Java support policy. The new major version of Oracle OpenJDK is only provided with 6 months of free support. However, there are community groups that provide open-source, long-term support for OpenJDK 11 binaries.

From Polarion 19.1 onwards, AdoptOpenJDK 11 (LTS) is the recommended JDK for runtime. Please refer to the Configuration.txt file in the Polarion distribution archive for a detailed description of configuration changes that need to be applied in relation to the switch to the OpenJDK.

Firefox 67 was also tested and added into the list of supported browsers.

 

 

Performance and Scalability

 

Optimized handling of UI preferences in a cluster

Polarion provides many user-level UI preferences, which are stored on the server-side, but not persisted in our Subversion repository, e.g. last visited URL, screen layout, recently used queries or favorite projects.

The handling of these UI preferences in a cluster has been significantly reworked and optimized to support seamless scalability to thousands of concurrent users. This data is now managed by the Polarion coordinator service in a cluster and leverages additional 2-level caching (on browser and server), which significantly reduces the number of IO operations.

Hi,

is that normal that only version 19.0 trail is downloadable for 19.1?

Also for the release 19.0 it was only possible to download 18.3

Siemens Theorist

Hi Schal.

 

In the last two releases, we were not able to align the update of the trial center with actual Polarion release date due to a dependency on an external team to update that content. However, we are taking measures to fix that situation for the next releases.

 

I've provided you with an alternative download location of the 19.1 version, so you can start the trial right away.

 

Best regards,

Radek Krotil
