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.

White list filter added for X-Forward-Host value security
Resolved in Pega Version 8.3.2
In order to improve security, a validation for X-Forward-Host value has been added which will be read from a local configuration. This is in the form of a white list regex filter for the host/XFHost header to ensure the URL's actions cannot be redirected.

Query parameters will be cleared after redirection from authentication
Resolved in Pega Version 8.3.2
When using the /PRAuth Servlet, running a snapstart URL generated from a secondary application correctly executed SAML Authentication and Pega processing, but a second URL generated with different parameters ran with the parameters from the first request. The third and subsequent requests processed as expected with the parameters sent in with the request. Investigation showed that the previous parameters were picked due to the query string parameters not being cleared after redirection, and this issue has been resolved by updating the system so it will clear the parameters after issuing a redirect from the authentication policy engine.

Updated HotFix Manager for use in older versions
Resolved in Pega Version 8.3.2
The DL logic in Hotfix Manager was changed in 8.3 to include the catalog of all framework changes. This had the unintended side effect of preventing DLs from being installed in Pega 7.3.1 and lower versions as the versions included in the catalog are not present on those systems and the validation failed. This has been resolved by revising the DL update so the system will only add all apps to the catalog for platform 7.4+ DLs.

Colon in folder or file name will be replaced with underscore during unzip
Resolved in Pega Version 8.3.2
After creating a product file (zip), attempting to import the same file into an updated system resulted in an exception. Investigation showed that in this case the zip file was a Product rule form which had applications packaged with a colon(:) in the name of the application, a format that was allowed in 6.x versions. Because Windows machines restrict creating creating any folder or file with : in its name, the zip file could not be inflated as part of the import process. To resolve this, the system has been updated so that a colon(:) will be replaced by underscore(_) during inflate operations.

Custom agent next run time will be rescheduled if the run failed
Resolved in Pega Version 8.3.2
If a customized agent that was set to run every day encountered an exception and failed to run, restarting the agent did not update it to the next run time; it still returned the passed trigger time as its next execution time. This has been resolved with an update that will reschedule the run if the next run time is in the past.
