Retry logic added for downloading upgraded rules
Resolved in Pega Version 8.2.8
A Rules upgrade failed while downloading applications from the maintenance server due to an SFTP server connection failure. This has been resolved by adding logic to retry if the first connection attempt fails.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.2.8
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved
Resolved in Pega Version 8.2.8
During index name generation, the algorithm that was responsible for index name uniqueness was sometimes insufficient and cerated a loop condition. This has been resolved by using a stronger hash algorithm and refactoring the code that could result in a loop.

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.

White list filter added for X-Forward-Host value security
Resolved in Pega Version 8.3.2
In order to improve security, a validation for X-Forward-Host value has been added which will be read from a local configuration. This is in the form of a white list regex filter for the host/XFHost header to ensure the URL's actions cannot be redirected.

Query parameters will be cleared after redirection from authentication
Resolved in Pega Version 8.3.2
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.

Updated HotFix Manager for use in older versions
Resolved in Pega Version 8.3.2
The DL logic in Hotfix Manager was changed in 8.3 to include the catalog of all framework changes. This had the unintended side effect of preventing DLs from being installed in Pega 7.3.1 and lower versions as the versions included in the catalog are not present on those systems and the validation failed. This has been resolved by revising the DL update so the system will only add all apps to the catalog for platform 7.4+ DLs.

Colon in folder or file name will be replaced with underscore during unzip
Resolved in Pega Version 8.3.2
After creating a product file (zip), attempting to import the same file into an updated system resulted in an exception. Investigation showed that in this case the zip file was a Product rule form which had applications packaged with a colon(:) in the name of the application, a format that was allowed in 6.x versions. Because Windows machines restrict creating creating any folder or file with : in its name, the zip file could not be inflated as part of the import process. To resolve this, the system has been updated so that a colon(:) will be replaced by underscore(_) during inflate operations.

Custom agent next run time will be rescheduled if the run failed
Resolved in Pega Version 8.3.2
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.
