Updated upgrade handling for migrating work objects
Resolved in Pega Version 8.3.6
After upgrading from Pega 6.2 to 8.3, the work migrated work objects were missing SLAs due to missed entries in the assignment tables (PC_ASSIGN_WORKLIST/ PC_ASSIGN_WORKBASKET) . The SLA was firing, but the processing failed due to the fact the runtime could not resolve a 'AddHistoryPage' library function. In this case, multiple upgrades of the application dating back to Pega 4 resulted in the runtime context containing older ruleset versions in higher ruleset versions, hiding the underlying Pega 8 version of the rule. For releases prior to Pega 7.3, Rule-Application was stored in pr4_rule and will be migrated to pr4_rule_application during upgrades. However, since Context Upgrade is run before Optimize Newly Exposed Columns, the pyDependsOnName won't always be populated. To resolve this, the system will filter based on the value in the blob rather than the exposed column so there will be a value regardless of the upgrade-from version.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.3.6
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

HTML entity handling added to URLObfuscation
Resolved in Pega Version 8.2.5
When URLObfuscation was enabled through the configuration settings, clicking on Operator -> Profile page generated an ArrayIndexOutOfBoundException. When obfuscation is used the decrypted string is parsed and the request map is populated, but HTML entities were not considered during this process. To resolve this, handling has been added for HTML entities and characters during obfuscation. Please note: URL Obfuscation is a legacy feature with many known limitations and it is no longer recommended that these settings be used.

Query parameters will be cleared after redirection from authentication
Resolved in Pega Version 8.2.5
When using the /PRAuth Servlet, running a snapstart URL generated from a secondary application correctly executed SAML Authentication and Pega processing, but a second URL generated with different parameters ran with the parameters from the first request. The third and subsequent requests processed as expected with the parameters sent in with the request. Investigation showed that the previous parameters were picked due to the query string parameters not being cleared after redirection, and this issue has been resolved by updating the system so it will clear the parameters after issuing a redirect from the authentication policy engine.

Data pages explicitly cleared after QP use
Resolved in Pega Version 8.2.5
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.

Custom agent next run time will be rescheduled if the run failed
Resolved in Pega Version 8.2.5
If a customized agent that was set to run every day encountered an exception and failed to run, restarting the agent did not update it to the next run time, it still returned the passed trigger time as its next execution time. This has been resolved with an update that will reschedule the run if the next run time is in the past.

SnapStart supports SAML2 Authentication
Resolved in Pega Version 8.2.5
When using an HTTP Post to SnapStart into Pega using PRCustom style or PRAuth style SAML authentication, the login was looping back to the login request. Investigation showed that the Pega ACS was posting data properly back to the RelayState URL, however the login activity was not getting the SAMLResponse and simply sent a SAML Login Request again. This has been fixed by updating reqContextURI in case of SAML2 Authentication service so pyActivity=value will be passed.

Cookie logging restored
Resolved in Pega Version 8.2.5
As part of security updates, Cookies were restricted from being logged. However, this caused some business use cases such as a custom function call to obtain the list of cookies that are present in the application to stop working. To resolve this, the cookie logging restriction has been reverted.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.2.5
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Column population honors thread count of 1
Resolved in Pega Version 8.2.5
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.
