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.

Check added for HTML and linefeed combined in email
Resolved in Pega Version 8.5.3
In the Interaction right hand pane Email triage widget, additional line breaks were seen when displaying email message data that contained table tags. This was a missed use case for email which contains both HTML and '\n', which resulted in the system replacing '\n' with </br>. This has been resolved by adding a check whether the content has HTML tags which will avoid the replacement.

Updated email triage case creation to avoid unique key issue
Resolved in Pega Version 8.5.3
After upgrade, when the email listener queued the case and an agent picked up the queued item to create an Email Triage Case and then the interaction case, trying to commit the case failed with a Unique Key violation. Investigation traced this to the system trying to insert the record into the PC_WORK_TRIAGE table twice due to a timing issue in the workobject commit. This has been resolved.

Changelog cleanup added for de-optimized properties
Resolved in Pega Version 8.5.3
Unwanted optimization was automatically added to properties for the Application-Work-Casetype class created using the wizard in the App Studio. Attempts to remove the optimization did not work: the property advance tab was showing the optimized classes details even after deleting and recreating the property. When a property is optimized the system adds entries to pr_changelog for the list of classes it has optimized. When the property was deleted, the pr_changelog was not cleared. This was a missed usecase, and has been resolved by overriding the Cleanup activity at Rule-Obj-Property class to delete the pr_changelog entry associated with that if it is present.

Database primary keys generated as NONCLUSTERED for imports
Resolved in Pega Version 8.5.3
When a primary key was defined for a table and the table was exported and then imported, the primary key was generated as CLUSTERED. This resulted in an MS SQL Cluster Index violation because all Pega-shipped tables generated during installs/upgrades have a PK constraint index with NONCLUSTERED index type as it allows for a longer key. This was a missed use case, and has been resolved by updating the system such that when importing with MS SQL database, the primary key index is made NONCLUSTERED all the time so it will be consistent with the base platform.

Pega Catalog custom upload control modified
Resolved in Pega Version 8.5.3
Attempting to upload a catalog.zip file caused the system to hang and thread dumps were seen in the logs. Investigation traced the issue to the custom control used to upload the catalog, which was posting the entire content in form data rather than sending a multi-part request. The control contained both legacy code which used form.submit() and encoding along with new code that used SafeURL and sent an async request. With this, encoding could not be set to multi-part in case of an AJAX request. To resolve this, the catalog upload control has been modified to use the appropriate legacy code that performs form.submit() and sets the encoding properly.

httpclients library upgraded
Resolved in Pega Version 8.5.3
Package import/export was not working using prpcserviceutils, and a SSLPeerUnverifiedException" error was seen. This was traced to an issue with the third party library httpclients v4.5.9, and has been resolved by upgrading to httpclients v4.5.13.
