Retry logic added for downloading upgraded rules
Resolved in Pega Version 8.1.9
A Rules upgrade failed while downloading applications from the maintenance server due to an SFTP server connection failure. This has been resolved by adding logic to retry if the first connection attempt fails.

Enhancements for upgrading in multi-tenant environment
Resolved in Pega Version 8.1.9
Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.1.9
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 8.1.9
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 for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.1.9
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Hot Fix Manager updated to use installation order for schema import
Resolved in Pega Version 8.3.5
Schema changes were not being imported during the hot fix manager DL import process. Investigation showed this was due to hotfixes in the DL being iterated over from newest to oldest, causing older hotfixes to replace the value added to a map by the newer. To resolve this, the system has been updated to use hotfix install order, which considers selected and dependent hotfixes, rather than ordering newest to oldest. This ensures that newer table representations will override older rather than the other way around.

SameSite cookie setting added for Mashup support in Google Chrome v80+
Resolved in Pega Version 8.3.3
The Google Chrome browser version 80 and above now treats SameSite with a blank value as "Lax" by default, causing mashup scenarios to break. In order to compensate for this change, support has been added for setting SameSite=None in Cookie Settings; this value automatically includes the “secure” cookie flag, which enforces HTTPS for the Pega server and mashup. For mashups to work, SameSite should be set as None. Create a Dynamic system setting in the Pega-Engine RuleSet with the name “security/csrf/samesitecookieattributevalue” and the value "None" and restart the server. (The SameSite value "None" works only in secure HTTPS connections.)Note: The SameSite cookie may be set to None/Lax/Strict, based on the requirement. For cookie requirements other than mashup, it should be set as either Strict or Lax, depending upon your application.

Column type configured correctly in Care Management
Resolved in Pega Version 8.3.3
When using database tables for concrete class groups with the column pyassignedoperator as character type without size, upon installation on higher environments the message "ERROR: length for type char cannot exceed 10485760 for colum "pyassignedoperator" CHAR (2147483647)" appeared. As a workaround it was possible to manually change the column type, but this issue has been resolved by updating the handling of BPCHAR types while cloning the table. BPCHAR type will be taken as CHAR.

DASS and DAS associated to the Pega-ProcessCommander Ruleset
Resolved in Pega Version 8.3.3
An upgrade was failing at the point of Pega Rules Upgrade in the Installer Instance with the error "Encountered database exception when preprocessing deferred operations <insert updatesCache instance DATA-ADMIN-SYSTEM PEGA not only if new>. This node not found in the database - Either the record was never saved or was deleted. Unable to join the cluster." This error occurred because the strategic application import during upgrade manually included a "systemname" DASS instance which had a value other than "prpc". This caused a override of the platform shipped DASS (with value "prpc), which is required by the upgrade. In order to avoid this condition, DASS and DAS have been associated to the Pega-ProcessCommander Ruleset.
