Resolved thread deadlock for rules upgrade process
Resolved in Pega Version 8.2.6
Platform upgrade was getting hung during the rules upgrade process. This was traced to a deadlock related to the conclusion cache entry for a property needing to make a call to declarative cache, where it tried to hold a read-write lock on a resource that was already locked by another thread. This has been resolved by replacing lock with tryLock to avoid deadlock.

Resolved in Pega Version 8.2.6

Performance improvement for queries on Kafka partitions
Resolved in Pega Version 8.2.6
Even though there were multiple dataflow nodes available in the cluster, all requests were going to single node and causing system slowness. Investigation showed there was a queue processor rule that included the pxPartitionKey attribute which forced all records to be sent to a single partition by Kafka producers. This attribute has been removed.

ClusterAndDBCleaner repaired
Resolved in Pega Version 8.2.6
An error in the logic order of events caused a compilation error for pyClusterAndDBCleaner, leading to old records created by the system/node utilities to not be automatically removed as expected. This has been corrected.

MSGraph email listener enhancements
Resolved in Pega Version 8.7
Attachments with .eml /.msg extensions were treated as FileAttachments by the MS Graph API and generating a classcastexception. To resolve this, a check has been added to identify the attachment along with content type so .eml will be correctly recognized. In addition, the MSGraph email listener functionality related to converting from Graph to MIME message has been enhanced around the 'TO' and 'CC' recipients in a MIME message and for parsing nested attachments in Item attachment for addition to MsgraphMessage.

Handling added for reactivating combined Passivation and AccessGroup timeout
Resolved in Pega Version 8.7
Refreshing a passivated browser window in Dev Studio for an operator with a combined access group and passivation timeout was resulting in a blank screen after re-authenticating. InvalidParameterException and InvalidReferenceException messages were logged. Research showed this was caused by a missing pxPortal property on the pxThread page along with missing Application and Accessgroup pages. While refreshing the browser along with the top URL, there will be few requests with tab threads calling activities such as deletedocumentpg and SetProcessWindowName because there was an unload. Because these requests reached the server before re-authentication, the threads proceeded to the activation flow, causing properties such as pxPortal, Application, and Accessgroup pages to be removed from the thread page and requestor page according to the condition that the requestor was not yet authenticated. To resolve this, the logic in session.internal.authorization.context.BasicApplicationContextImmutableImpl#applyApplicationProperties has been updated to skip removing application page properties from the thread page in this combined Passivation and AccessGroup timeout scenario.

Bulk actions check in preserves declare expression legacy setting
Resolved in Pega Version 8.7
When a declare expression was saved in legacy mode with "Whenever used" selected in change tracking, performing a bulk check-in of the rule caused the expression to default to the new forward chaining method. This did not occur when using a direct check-in. Investigation showed this was caused by the check-in page holding a legacy value before the step execution, and has been resolved by adding a pre-save activity before the validation activity that will restore the .pyIsLegacy value from .pyExpressionTypeSelector, if set.

Query added to find time zone for MSSQL database
Resolved in Pega Version 8.7
The exception "com.microsoft.sqlserver.jdbc.SQLServerException: xp_regread() returned error 5, 'Access is denied.'" was generated when the AES agent PushDBSizeInfo was being run. This was traced to the GetDBInfo activity trying to retrieve the time zone of the MSSQL database by executing a query that used a Microsoft SQL routine to read the windows registry to get the current time zone. The error was not due to security within the SQL Server, but instead was caused by Microsoft Windows security related to the permissions on the registry keys for the users under which specific SQL Server processes were running. To resolve this, an update has been made to call a different query which will get the time zone for the SQL Server.

PEGA SOAP Service MTOM attachment handling updated
Resolved in Pega Version 8.7
After configuring a PEGA SOAP service with the Enable MTOM checked, sending a SOAP request with attachment to the service returned an invalid request error stating "Value of content length header is greater than zero - [762], but this request has empty POST". Investigation showed that when the input request reached the getPostBytes method and inputstream tried to read it, there were no available bytes and end of file was detected. This was due to the inputstream having already been read in getMultiPartSOAPHandler() method in FileUploadHandler class. To resolve this, the system will update an 'if' condition in getPostBytes method to skip reading the request attachment when contentType is "multipart/related".
