Performance improvement for message processing
Resolved in Pega Version 8.7
Severe performance degradation was seen for message processing in pdc-central after update. Investigation showed there was an issue with a write lock not not being acquired while reloading the datapage definition, causing concurrent dirty reads and multiple definition reloads. To resolve this, DeclarativePageDefinitionCacheImpl has been updated to acquire a write lock to prevent dirty reads of the same stale data page definition while reloading.

Added pause after Library Extraction to ensure Rule-Utility-Functions are present
Resolved in Pega Version 8.7
After upgrade from Pega 7 to Pega 8, nodes were not starting and the error "pub.context.InitializationFailedError: PRNodeImpl init failed" appeared. This was traced to an issue with the pzSharedTenant rule: when pzSharedTenant (Rule Access When) is assembled by the system, it uses the compareTwoValues Rule-Utility-Function. If the system is not able to find the correct version of compareTwoValues, it adds an UnresolvedAssemblyError in the assembly of the pzSharedTenant, causing the startup failure. This has been resolved by adding an await call after the LibraryExtraction task to wait for it to complete. This wait will ensure that the library extraction task completes before starting the search task which uses Rule-Utility-Functions

New or updated operators properly updated on other nodes
Resolved in Pega Version 8.7
Newly imported or updated operators were not getting properly pulsed to other nodes. This was traced to operator pages being cached while the system pulse for 'Data-Admin-Operator-ID' was not permitted on the allow list, and has been resolved.

Corrected unnecessary Severe Warnings for MSGraph account
Resolved in Pega Version 8.7
After configuring an email account with MSGraph settings and saving the the email account instance, three unneeded severe guardrail warnings were generated related to using D_pxGetApplicationSettingValue instead of a constant value. This has been resolved.

Handling added to correct class setting during DX-API
Resolved in Pega Version 8.7
When a DX-API call was made (assignments/{ID}/actions/{actionID}/refresh) the ApplyPageInstructions activity was updating the case with an incorrect class, causing the rules from the wrong class to be picked and blocking the case progression. This has been resolved by setting the proper parameter Param.workPage while calling pzApplyPageInstructions from pzUpdateCaseWithRequestBody to calculate the proper class for the content.

Service Email handling updated for MSGraph "From" address
Resolved in Pega Version 8.7
While creating cases via email listener, the "From" address was not shown when using MSGraph. This was an issue with extracting the display name when MSGraph is used, and has been resolved by adding double quotes to display the name unconditionally.

Additional diagnostic logging added for ElasticSearch startup issues
Resolved in Pega Version 8.7
The PyIndexerState was stuck in Starting status during node initialization. This issue could occur if the filesystem became hung due to network level issue while scanning entries from /etc/mtab, resulting in a lock which was not released correctly. In order to better determine which node entry in a cluster may be responsible for the hang, an update has been made which will use a temporary virtual environment to repeat the part of the initialization phase responsible and generate additional logs for debugging. To activate this, the PegaSearch.Diagnostics logger must be set in DEBUG mode. This duplicated virtual initialization will not interrupt the normal initialization.

Updated replica management for search clusters
Resolved in Pega Version 8.7
When using a cluster with two Universal nodes in the cluster, a daily restart process where the second node was not started until the first was fully up resulted in Search initialization failing for the first node while becoming active on the second node. This was traced to the methods used in increasing and decreasing replicas. This has been resolved by revising the handling of ElasticSearch node lifecycle and replicas through a new option "Dindex.searchNodeCount " which includes a specification for the number of expected search nodes. If this option is not present, the old method will be used.

Logic updated to allow page property and declare index with the same name
Resolved in Pega Version 8.7
A Property which was in a Pagelist which in turn was embedded in a Page was not visible in the Report Browser. This was traced to the two properties sharing the same name, and was caused by a check which ensured only entries with unique names were added. In order to support this configuration, logic has been added to pzAddPropListForClass_TreeGrid such that if a page property and declare index share the same name, they are both added to the tree grid.

DSS added for handling missing attachments
Resolved in Pega Version 8.7
When an S3 repository was configured as storage, some cases were not coming up in search and exception errors were seen in logs for a deleted attachment after every system restart/re-indexing of the search. Investigation showed these case objects were in the broken queue for pyFTSIncrementalIndexer due to a null pointer error encountered when indexing the attachment, and that the attachments were available in the repository but could not be read from the attachment repository during indexing. To resolve this, a new DSS setting has been added which allows selecting one of two behaviors: * Pega-SearchEngine indexing/distributed/fail_on_missing_attachment_file = true : broken item is generated, but with a meaningful error message. This is the default behavior * Pega-SearchEngine indexing/distributed/fail_on_missing_attachment_file = false: case is indexed, but without the problematic attachment. Error message is printed out to the logs.
