INC-146752 · Issue 602935

File Listener made more resilient

Resolved in Pega Version 8.4.4

When file listener encountered a FileNotFoundException as a consequence of sporadic AmazonS3Exceptions, the listener was disabled and no retries were made. In order to make the file listener more resilient, FileMatchConcentrator has been updated. While file listener is running and trying to get the next set of files, if the isDirectory() method returns false due to a non-existent directory or some other intermittent issues, instead of throwing an exception and shutting down the file listener, the system will now log the exception and continue.

Email listener update for Microsoft Exchange server

Resolved in Pega Version 8.4.4

After upgrade, TooManyObjectsOpenedException/MapiExceptionSessionLimit errors were seen when starting the email listener. Investigation showed that when the listener was started, two sessions were getting opened and then not closed properly. This was a method originally intended to allow the system to re-use the session to minimize performance overhead, but it is not well-suited for use with Microsoft exchange server as the Exchange server is unable to cleanup idle sessions. As a result, too many MAPI sessions were opened and led to an authentication exception while opening additional sessions. To resolve this, an update has been made so the system will close the session while the listener sleeps. This stop, restart and graceful shutdown scenario for single threaded email listener scenarios will create a new session every time and close it properly.

Enhanced logging added to REDUX query references

Resolved in Pega Version 8.4.4

Diagnostic logging has been added to REDUX query references which will capture information about exceptions that cause the system to fallback to generating legacy references.

INC-147873 · Issue 610864

Custom header character encoding for Subject added

Resolved in Pega Version 8.4.4

Case correspondence that contained a Subject with accent characters such as "Invitation à être" was being rejected by MailJet on the basis of encoding issues on the "Thread-Topic" when using custom headers. The error "BAD HEADER SECTION, Non-encoded non-ASCII data (and not UTF-8)" was generated. This was traced to the Send Email Smart Shape handling when using custom headers, and has been resolved by encoding the Subject before appending it to the Thread-topic header while adding custom headers.

INC-148414 · Issue 615594

Date field correctly extracted for IMAP inbound email

Resolved in Pega Version 8.4.4

After upgrade, email-sourced cases were not being created correctly. Tracer showed the date field was blank, causing an error which was traced to the getReceivedDate being returned as null for the JavaMail AP even though the IMAP protocol was being used. This was an unintended side effect of work done to handle a throttling exception in the IMAP inbound email flow, and has been resolved by updating the system so that if the getReceivedDate is null, the date will be extracted from the mail header while processing dates in EmailMessageInfo class.

INC-148944 · Issue 604102

Email Listener auto-reply evaluation updated

Resolved in Pega Version 8.4.4

After upgrade, messages were being read but not getting processed for a specific Email listener (RCEmailListerner). The error "Email flagged as an autoreply email and will not be processed" appeared in the logs. Previously, an email was not considered to be an auto-reply only when the 'auto-submitted' header didn't exist or existed with value 'no'. This caused issues with auto-forward or auto-redirect emails where 'auto-submitted:auto-generated' could be in the header. Due to this, email was marked as auto-reply and email listener stopped processing it. To resolve this, the system has been modified to mark the message as auto-reply if it finds 'auto-submitted: auto-replied' in the header, but not 'auto-submitted:auto-generated'.

INC-149370 · Issue 619990

Logging for MultiNodeSynchronize lock attempts changed from error to warn

Resolved in Pega Version 8.4.4

The File Listener was logging numerous errors stating "Unable to establish MultiNodeSynchronize lock while trying to determine if listener is enabled for this node". Handling has been previously established for error cases when the Listener is unable to establish a MultiNodeSynchronize lock, but this condition continued to be logged as an error even though it was not related to any failures in functionality. To resolve the logging issue, the logger level has been changed from ERROR to WARN.

INC-149375 · Issue 607831

Adjusted email listener behavior for authentication failures

Resolved in Pega Version 8.4.4

After upgrade, email listeners were not staying up during connection outages. This was traced to the handling of authentication failures when trying to reconnect, and has been resolved by changing the disconnected listener state to sleeping and raising an alert for authentication failures.

INC-149517 · Issue 609475

Secure access for Activities

Resolved in Pega Version 8.4.4

Authentication requirements have been added to Standard activities.

INC-150038 · Issue 614828

Data Type local data storage snapshot history updated

Resolved in Pega Version 8.4.4

When a History Class Data object was created, two snapshots were made - one with value and another with no value. This was traced to a 'when' condition that evaluated whether to add history when deleting a record from records editor, and this issue has been addressed by removing the condition as the history-add step takes care of checking if there is a dedicated table or not.
