SR-B48902 · Issue 318395

PegaMarketing localization tuned

Resolved in Pega Version 7.3.1

While localizing the Pega Marketing application, English strings were found in several places from Decisioning in particular, but also in the Platform in general. The localization for these has been fixed.

Improved performance for Proposition updates

Resolved in Pega Version 7.3.1

While updating propositions through DSM portal it was observed that the thread count got very high while overall performance became degraded. This happened in Pega versions where the propositions are data instances and not rules. The issue was traced to the Proposition cache getting reloaded from the database table in a synchronized block; all of the strategy execution threads were waiting until the reloading completed despite strategy reading the propositions from the cache. To resolve this, the system will reload the proposition cache from the database table in the thread where the pulse message is being processed when the node receives the pulse notification. Thus other strategy execution threads will not be blocked and continue reading propositions from the cache.

Cassandra fixes for AIX systems

Resolved in Pega Version 7.3.1

A Cassandra node start failure on some AIX environments was traced to a condition for checking whether Java version 1.7 and 1.8 in file cassandra-env-AIX.sh were present in the dnode-7.2.1.jar. This check is not necessary as the same check is already performed in Cassandra.java class, and it has been removed from the cassandra-env-AIX.sh script. Additionally a new system setting dnode/overwrite_cassandra_env has been introduced to allow disabling replacing cassandra-env.sh script with cassandra-env-AIX.sh (which is normally done on AIX systems).

SR-B66892 · Issue 315757

Cassandra support enhanced for CQL 3 data types

Resolved in Pega Version 7.3.1

The connector was unable to read a date-filed value from Cassandra to Pega Dateonly or varchar datatype, instead failing with an exception. As a result, data was not readable via connect-Cassandra if that table had new column types like (date,time,tinyint,smallint). To resolve this, data type support has been added for the new types in CQL 3.3 (smallint,tinyint,date,time).

SR-B70652 · Issue 325760

Read operations updated for Datastax 3.1.x use

Resolved in Pega Version 7.3.1

In the 3.1.x Datastax driver reads are no longer retried by default. Therefore, the read operations have now been explicitly marked as idempotent to force the Datastax driver to retry timed out reads.

SR-B70652 · Issue 325924

Timeout error resolved for write future

Resolved in Pega Version 7.3.1

With retries enabled, the write future was timing out before retries could be completed. This has been fixed by removing the timeout on the write future since timeouts will be caught using Datastax driver exceptions.

Facebook connector refined to handle page deletion while the AADrivetech is active

Resolved in Pega Version 7.3.1

A Facebook connector trying to connect to a invalid page was causing out of memory errors. In this scenario, a Facebook Page that was no longer required was deleted but the AADrivetech Facebook connector was left running. This connector, in its attempts to contact the Facebook page and retrieve the getFrom parameter which was now null, started to consume resources on the node leading to the outage. To solve this, the code has been modified to not expect the user name to always come from Facebook but instead put in an anonymous name if the page disappears.

Backwards compatibility enhancement for @when() validation

Resolved in Pega Version 7.3.1

After upgrade, a Strategy rule which referred a 'when' with the syntax @when(isOnlineApplication) was failing with design time validation saying that when rule was not found in the SR and instead it had to find it in the Customer/Applies to class. For the @when() issue, the root cause was that the validation context of @when() was switched from Applies-To class to the Step Page class due to a change in the core engine. The behavior of expression parsing for when rule calls was changed in release 7.2. It used to take the Apply-to class to validate the existence of the rule, but not it is taking the Step Page class. And Strategy rule doesn't push/pop stackframe due to performance reasons, thus StepPage on stack for Strategy is always the same as Primary page. For greater compatibility, the system will set the PageContextClass to the Apply To class so the expression parser can validate the setup which is expected at run-time.

SR-B37374 · Issue 309750

null-pointer exception fixed for missing rule class

Resolved in Pega Version 7.3.1

After upgrade, a null-pointer exception was generated when the class on which a rule was defined no longer existed and there was a withdrawn rule in the hierarchy. This has been fixed.

SR-B40801 · Issue 317066

Check added to ensure downloaded files match the extension type given

Resolved in Pega Version 7.3.1

In the remote application that provided functionality for downloading files, no validation was performed on the requested file extension or file name during the request; these values could be constructed in the file request. However, this could allow attackers to send malicious links to end users by forcing a file to have a specific file extension such as .exe, .html, or .bat . In order to prevent issues, a check has been added to see if the extension of the filename and the actual file extension match. If they do not, the file will not be downloaded.
