Resolved thread deadlock for rules upgrade process
Resolved in Pega Version 8.2.6
Platform upgrade was getting hung during the rules upgrade process. This was traced to a deadlock related to the conclusion cache entry for a property needing to make a call to declarative cache, where it tried to hold a read-write lock on a resource that was already locked by another thread. This has been resolved by replacing lock with tryLock to avoid deadlock.

Encoding added for special characters in JFROG filenames
Resolved in Pega Version 8.2.6
A blank screen or the error "Unable to get the file from Repository" appeared when attempting to attach a file from JFROG Repository if the file name contained special characters. This has been resolved by modifying the artificatory URL generation to properly encode special characters during file download.

Performance improvement for queries on Kafka partitions
Resolved in Pega Version 8.2.6
Even though there were multiple dataflow nodes available in the cluster, all requests were going to single node and causing system slowness. Investigation showed there was a queue processor rule that included the pxPartitionKey attribute which forced all records to be sent to a single partition by Kafka producers. This attribute has been removed.

ClusterAndDBCleaner repaired
Resolved in Pega Version 8.2.6
An error in the logic order of events caused a compilation error for pyClusterAndDBCleaner, leading to old records created by the system/node utilities to not be automatically removed as expected. This has been corrected.

Run Ruleset Cleanup defaults to true
Resolved in Pega Version 8.2.6
After upgrade, the rule categories and rules were not showing correctly in the App view of the Dev Portal. Many warning messages were also logged related to the Decisioning DM Sample application. This was traced to the rules cleanup script not running properly. While there was a workaround of applying the ruleset cleanup scripts manually after removing the queries that reference the pr_engineclasses table, the cleanup will now be set to run by default (run.ruleset.cleanup=true). In addition, the logic to determine which RuleSets to include has been simplified and most of the pr4_rule_vw deletions have been combined.

Data pages explicitly cleared after QP use
Resolved in Pega Version 8.2.6
The Util Node was showing as Offline in the Search Landing Page, and when Jobs were submitted for execution from other Nodes the message "Detected active run with unreachable nodes" was logged. The util node, configured as a backgroundprocessing node, was running QPs; the queue size for custom QPs is 500 messages /queue items per minute, but investigation showed the requestor level and thread level data pages corresponding to the QP activities were not being cleared after use. This led to high heap memory issues that made the node unreachable, and has been resolved by adding code to explicitly remove the data pages when processing has finished.

Hazelcast upgraded to resolve node startup issue
Resolved in Pega Version 8.2.6
Post data upgrade, the ADM tier failed to start and the error "java.lang.IllegalStateException: Node failed to start!" appeared. This was traced to a dormant bug in Hazelcast 3.11 that caused starting nodes to fail when the Hazelcast master node was shutting down, which was exposed by recent Pega changes made to enable parallel restarts of nodes in Cloud environments. Hazelcast delivered a fix for the parallel restart problem and the hotfixed jar has been merged into the platform. In addition, previous logic for loading Admin Studio waited 30 seconds before timing out when fetching information for each node. This caused issues with large clusters and Admin Studio not loading. The logic has been updated in the Admin Studio UI to load the page despite delays/issues waiting for nodes to respond to the gathering of cluster data, and the algorithm to detect remote-call timeout has been updated and is applicable to batch operation.

Exception handling added for Redirect URL fetched from GRS
Resolved in Pega Version 8.2.6
When the application definition under “integration and security" tab was configured to use "Store in web storage provider" to allow choosing the storage name and the authentication profile, configuring the authentication profile to use an OpenID connect provider with the pyEndpointURL property given as a global resource setting such as (=D_SharepointDetails.url) was not working as expected. Clicking browse in the application definition sent the request to the OpenID connect provider and was returned with the error "The reference =D_SharepointDetails.url is not valid. Reason: Page name (D_SharepointDetails) from indirect reference was not found." This was traced to the Redirect URL (fetched from GRS) throwing an unhandled exception, and has been resolved.

Enhancement added to support DB2 CREATE OR REPLACE view syntax
Resolved in Pega Version 8.2.6
After creating the product, attempting to import it on another environment failed due to incompatibilities with the syntax. In SQLGeneratorDb2.getViewSourceStatement(), when the View definition is fetched there is a check whether the view starts with "CREATE VIEW". Since the customer view of "CREATE OR REPLACE" was not supported in Db2LUW, it didn't match and appended the "CREATE VIEW" statement again. This happened only when using DB2, and has been resolved by updating the logic in SQLGeneratorDb2.getViewSourceStatement() to support CREATE OR REPLACE VIEW statements.

Hierarchical view support added for moving packages
Resolved in Pega Version 8.2.6
After exporting a package from a DEV environment, attempting to import it to a TEST environment resulted in the query becoming corrupted and the process failing. This was traced to the regex used to fetch the select statement table name not supporting hierarchical views, and has been resolved by adding that support.
