Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

File Dataset wildcards updated for ADM storage
Resolved in Pega Version 8.7
Attempting to access the filepath was failing and an error was seen indicating "Could not obtain lock 'Create repository file pegacloudfilestorage:ADM/Rule-Decision-AdaptiveModel/Data-Decision-Request-Customer". While creating a file name, a lock is generated while checking the file names of existing files. If the file data set has a large number of files, a condition may occur where some threads are unable to save data and an exception is thrown. To resolve this, the wildcard previously used in the file name has been replaced with the Pega node id + thread id + current timestamp. This will ensure all wildcards are unique and there is no need to lock and list existing files.

Improved handling against formula injection attacks in Export to ExcelJJ
Resolved in Pega Version 8.5
Every time a possibly vulnerable cell value was found during Export to Excel, the value on that cell was modified to prevent a formula injection attack. If the value was non numeric, it would still render an apostrophe, although it should be hidden. Previous work on this issue involved the addition of a DSS which allowed this security to be disabled if the Excel was going to be consumed by an external tool, but the security implementation used to protect against calculation injection has reworked the ExcelSecurity utility function to allow the ability to change the cell style of a cell that is potentially vulnerable to formula injection attacks. This change no longer changes the cell value but instead applies a new cell style that has quotePrefix enabled.

Case Archive updated to better prune email and attachment metadata
Resolved in Pega Version 8.7
After configuring pyPegaArchiver, pyPegaIndexer and pyPegaPurger to remove old cases, there were no records present in the pr_metadata table but the records related to Data-Corr-Email, Data-WorkAttach-File and Link-Attachment remained. As there is no harm in removing these entries because the system has already copied the reference to these attachments, the entry in pr_metadata can be removed without any issue. With this update, external and shared entries now get removed from pr_metadata table when a purge is performed, however they do not get removed from the target table.

Resolved erroneous problem assignment error
Resolved in Pega Version 8.5
If a user processed a work item while the SLA agent was also attempting to process it, it sometimes resulted in an assignment with the error: "Error: Flow Not At Task." In this scenario, an error message was displayed stating that "Assignment already completed" even though the assignment was not yet finished, causing confusion. Investigation showed that in cases where the success indicator was -28, the assignment was marked as problem assignment even though it was processed. To resolve this, the system has been updated to skip marking the assignment as a problem when the success indicator is -28.

Approved flow rule image unlocked
Resolved in Pega Version 8.5
When the Approval Required check box was enabled for rulesets (i.e another person with access to this work queue should approve changes to the rules), a rule which was approved was unlocked and moved back to the original ruleset as expected, but the binary image associated with the flow rule remained locked and any other user other than the one who previously checked in the rule was denied access with a "check out failed" error. This locking error has been resolved by modifying the Rule-Obj-Flow!CleanUp activity to set Param.IgnoreInstanceLockedBy = true.
