Check added for Repositories before saving attachment
Resolved in Pega Version 8.2.6
When creating or updating a case through email listener, the Link-Attachment defaulted the pxStorageType to 'WebStorage'. This caused an issue when using PegaS3, which needs pxStorageType 'Repository'. To resolve this, a check has been added to see if Repositories are enabled, and if they are the storageType will be set accordingly.

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.

Encoding added for special characters in JFROG filenames
Resolved in Pega Version 8.2.6
A blank screen or the error "Unable to get the file from Repository" appeared when attempting to attach a file from JFROG Repository if the file name contained special characters. This has been resolved by modifying the artificatory URL generation to properly encode special characters during file download.

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.

Handling added for reactivating combined Passivation and AccessGroup timeout
Resolved in Pega Version 8.4.6
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.

Handling updated for queue processor locks
Resolved in Pega Version 8.4.6
The Final activity mentioned in the processing epilog of the Service File rule was not being consistently called from File Listener, causing some of the cases to become stuck and not continue to the next stage. Investigation showed that if the lock was held by the queue processor requestor, the system was unable to obtain the lock but still proceeded to update the LogServiceFile page and persist it. This resulted in overwriting changes made on the LogServiceFile page by the requestor, resetting the completed-batches-count set back to 0. To resolve this, RuleServiceFile -> updateLSFBatchCounts() will call the overloaded lockAndLoad() method in LogServiceFile that accepts a parameter called lockAttempts. This will attempt to obtain a lock for a given number of times before throwing an exception.

Queue Processor threads explicitly cleared before new interaction
Resolved in Pega Version 8.4.6
Queue Processor was not clearing already evaluated freshness caches before running an activity, potentially causing a stale data page to be processed. This has been resolved by explicitly clearing the thread on a new interaction by invoking ((IPRThread) thread).clearOnNewInteraction.
