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.

Repaired Tracer use with Google Chrome
Resolved in Pega Version 8.5
After running Tracer while using Chrome, closing it and trying to run another resulted in an error indicating "Cannot Launch multiple tracer sessions for a requestor". This was identified as a bug with Google Chrome Versions greater than 70 and was caused by Chrome deprecating the use of sync XHR on page dismissal, and has been resolved by modifying the system to use a beacon API instead.

API added to sync presence with requestor to clear inactive operator sessions
Resolved in Pega Version 8.5
An intermittent error message was seen indicating the maximum number of active sessions for the current operator had been reached even though there were not multiple logins and there was no requestor displayed in the requestor management landing page. This was traced to sessions that were not properly closed and cleared, and has been resolved by exposing an API that will sync the presence record with the requestor state so inactive sessions will be cleared.

Corrected filedownload extension header issue
Resolved in Pega Version 8.5
Filedownload header contained plain non-ascii characters which caused a security violation issue. This has been resolved by removing the filedownload header from the HTTP response when the sendfile API is used with inputstream to download a file.

Atmosphere library updated
Resolved in Pega Version 8.5
Multiple setAttribute exceptions were logged related to the Atmosphere component, indicating "The request object has been recycled and is no longer associated with this facade." Investigation showed that since the request object was destroyed, an illegalstateexception was thrown. To resolve this, the Atmosphere library has been updated to version 2.4.5.7 which contains the fix for this error.

Tracer expiration set for five minutes
Resolved in Pega Version 8.5
Tracer was not terminating on tracer window closure. On the next attempt to open a trace, a message appeared stating "Cannot Launch Multiple Tracer Sessions for a requestor. This requestor is being traced by operator". Tracer session termination was dependent on the browser executing code on window close. Because this event may not be triggered for number of reasons, updates have been made to set tracer session expiration at 5 minutes. In addition, the system will clean up expired sessions before checking for existing sessions.
