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.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.6.1
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.6.1
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.
