IOException handling improved to resolve broken pipe errors
Resolved in Pega Version 8.4.2
Frequent "connection reset by peers" exceptions were being generated and broken-pipe exceptions were seen in the logs. Investigation traced the issue to unhanded IOExceptions on the server side that were a result of the client application not always closing the TCP connection gracefully. To resolve this, error handling for IOExceptions has been improved.

Directory traversal blocked in zip import
Resolved in Pega Version 8.4.2
One of the files contained in a zip archive was not deleted from the system after zip import. This was due to the file being created by a third-party archive that included of a directory traversal character that caused it to be inflated outside of the temp directory. To resolve this, a check has been added to that a file with directory traversal characters in its name will not be inflated.

JDBC URL handling added for Oracle over TCPS
Resolved in Pega Version 8.4.2
While attempting to upgrade an environment over TCPS, the generateDDL.sh script was failing. The same environment ran without issue on Tomcat with the same URL. Investigation showed the JDBC url was not correctly generated while running the upgrade: in a standard scenario, there will be no spaces in the JDBC URL specified. However, because Oracle can send spaces as part of JDBC URL and cause this issue, an update has been made which will quote the JDBC URL argument for the ant target in setupDDL.xml.

Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.4.2
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

ProductInfoReader updated to fetch only most recent version information
Resolved in Pega Version 8.4.2
After upgrade, running Hfix scanner on Pega Marketing 8.2 displayed missed critical Hfixes for Pega Marketing 8.1. This has been resolved by modifying ProductInfoReader.runQuery to fetch only latest version of DAPF instances during a scan.

Handling added for hotfix Rule-Application instances
Resolved in Pega Version 8.4.2
A null pointer error during DL file expansion performed as part of the second phase of a hotfix installation caused the hotfix install to fail. The null-pointer exception was thrown because the code, primarily used for export, performed a database lookup of a Rule-Application and assumed the response would be non-null without checking the result. During export the Rule-Application would normally exist because the system would have interacted with it already during the export by identifying it and writing it to the archive. During phased hotfix installation, rules are staged to the database in a different table during the first phase and reconstituted during the second phase. The scenario for this error was a missed corner case specific to the unusual combination of including Rule-Application instances in a platform hotfix. To resolve this and prevent further issues, handling has been added for this use case.

Property Rule Form refreshes after discarding changes
Resolved in Pega Version 8.6.2
After updating from Pega 8.2 to Pega 8.6 and migrating the properties, modifying any property rule and then discarding the change did not refresh the Property Rule Form. Investigation showed that the LOG-SYSTEM-PROPERTYOPTIMIZATION instance created during property optimization was not getting deleted when a property was deleted. As this was not getting deleted, the property was shown as optimized when adding the property back, causing confusion. This has been resolved by cleaning up the LOG-SYSTEM-PROPERTYOPTIMIZATION instance when the property is deleted and there is an optimization entry.

Additional diagnostic logging added for ElasticSearch startup issues
Resolved in Pega Version 8.6.3
The PyIndexerState was stuck in Starting status during node initialization. This issue could occur if the filesystem became hung due to network level issue while scanning entries from /etc/mtab, resulting in a lock which was not released correctly. In order to better determine which node entry in a cluster may be responsible for the hang, an update has been made which will use a temporary virtual environment to repeat the part of the initialization phase responsible and generate additional logs for debugging. To activate this, the PegaSearch.Diagnostics logger must be set in DEBUG mode. This duplicated virtual initialization will not interrupt the normal initialization.

Updated replica management for search clusters
Resolved in Pega Version 8.6.3
When using a cluster with two Universal nodes in the cluster, a daily restart process where the second node was not started until the first was fully up resulted in Search initialization failing for the first node while becoming active on the second node. This was traced to the methods used in increasing and decreasing replicas. This has been resolved by revising the handling of ElasticSearch node lifecycle and replicas through a new option "Dindex.searchNodeCount " which includes a specification for the number of expected search nodes. If this option is not present, the old method will be used.

BIX Total Instance count matches manifest
Resolved in Pega Version 8.6.3
The BIX Manifest file was showing a count mismatch when the BIX Manifest and Extract files were shared with downstream teams, causing data to not be accepted by the downstream application. Investigation showed this occurred for an embedded page list property in the sequence that was missed and not considered. To resolve this, a DSS has been added: when BIX/generateAllEmptySubscriptForPageList is set to true, an empty subscript will be generated for the missed properties.
