SR-D53835 · Issue 524214

Handling added for custom authentication in embedded mashup

Resolved in Pega Version 8.4.1

After embedding the Mashup gadget in an external application, at browser refresh a Cross-Origin Read Blocking (CORB) warning appeared and the gadget did not load as expected. A second refresh cleared the error. Investigation showed that when custom authentication is configured, 'use SSL' is checked in Authentication service. That meant that when the user was authenticated, the redirection was not considering the query string entered before authentication and the CORB warning was issued due to a change in response. Because there is special handling for the above use case and post-authentication redirection does not happen through the normal flow (HttpAPI), this issue has been resolved by honoring the query string stored in requestor (entered by user) while redirecting.

Delete Requestor method updated for use with CMT

Resolved in Pega Version 8.4.1

JMS MDB Listeners with Container Managed Transaction (CMT) enabled in Websphere 8.5 had global transactions fail. To initialize a JMS-MDB listener, a requestor of type APP is used. Upon the service being fully initialized, the requestor is removed by executing a delete operation followed by a COMMIT. However, in this scenario, the initialization operation is running within a CMT context and a SQLException was raised indicating that the commit was not allowed. To resolve this, the delete requestor method has been refactored to take into account the CMT context so the commit is not executed if the transaction is managed by the container.

Logic update for classloading synchronization

Resolved in Pega Version 8.4.1

The synchronization logic for classloading has been updated to resolve intermittent deadlocking seen when two DataFlow threads are executing a distribution test.

Application/CSV type explicitly included to assist Android Chrome

Resolved in Pega Version 8.4.1

Android Chrome was unable to recognize a CSV file under content-type="application/*" , resulting in the download being rejected. To resolve this, "application/csv" will be explicitly included in the request content type when appropriate.

Compilation logic error corrected

Resolved in Pega Version 8.4.1

A compilation failure on upgraded systems using the JDK 11 compilation of libraries that include Pega 7 functions that have INCLUDE statements that are not supported in JDK 11 was traced to a logic error added when enhancing debug logging. This has been corrected.

SR-D64608 · Issue 544389

Corrected filedownload extension header issue

Resolved in Pega Version 8.4.1

Filedownload header contained plain non-ascii characters which caused a security violation issue. This has been resolved by removing the filedownload header from the HTTP response when the sendfile API is used with inputstream to download a file.

SR-D66615 · Issue 536243

API added to minimize calls to set parameters in datapage

Resolved in Pega Version 8.4.1

Differences were seen after upgrade when using a datapage associated with a property which was application-specific and that had Data Access for the property defined as “Copy data from a data page" with parameters whose value was set by an activity from the associated property of type single page. Prior to upgrade, only one call was seen to set the values for the parameters in datapage, but post-upgrade multiple calls were used to set the values to these parameters. This was traced to logic used for extraction and invoking the perform, and has been resolved by adding the new API 'DeclarativeAction.shouldExtractWatchedProperties'. It will return true or false, depending whether the extraction of watch properties is needed or not.

DSS added for fall back to legacy decision table format

Resolved in Pega Version 8.4.1

After upgrade and switch to IL, non-working decision tables created in one class had pyWorkPage mapped to another class. In the column, the properties were mentioned as "pyWorkPage.xxxxx", but at runtime when the non-working decision tables ran as standalone, the system did not ask for values to be entered to evaluate the result. Tracer showed the error as "Goal seek requires missing input property pyWorkPage.All_Offln_Trans_In on page pyWorkPage; details: (unknown)". Investigation showed that the Legacy assembly for the decision table used the lazy evaluation pattern to resolve the expression in the column header in the generated Java code. This resulted in the property for the column header only being read when it was used. However, for IL-based decision tables all properties are read immediately before any rows are evaluated, which requires the property already be present on the page. This missing property from the lazy assembly then resulted in the exception. To resolve this, Executable.generateOrCompileSource and Virtual tableassemblyHandler.useIL() have been modified to fall back to legacy decision table format if the DSS InternalLanguage/disableIlBasedDecisionTable is enabled.

Enhanced diagnostic logging for automatic search re-index

Resolved in Pega Version 8.4.1

To better analyze an out of memory error, enhanced diagnostic logging has been enabled for the below classes to get more information regarding re-index triggered automatically after search index is complete.PegaSearch.SearchManager.SearchInitlizationUtils PegaSearch.SearchManager.BuildIndicesTask Rule_Obj_Activity.pzLPFTSManagerRunBuildIndex.Pega_Search_Manager.Action PegaSearch.Indexer.AbstractIndexer

SR-D71041 · Issue 537897

Default compiler pool size increased

Resolved in Pega Version 8.4.1

An issue was seen where the nodes were continuously terminating and Stream service was not started. Error messages indicated a "WARN - Long running request detected for requestor", and that tasks were waiting for the generic object pool. Analysis showed that it was possible for a deadlock to form during the startup of the system or during the first few rule executions and compilations when there were more than five rules trying to compile. Once the variable LibraryMetadata.TypeEnvironment.resolver (ClassLoader) is initialized, the problem would resolve. To prevent the deadlock, the default compiler pool size has been increased from 5 to 10.
