HTTPClient updated to match Apache's ConnectionRequestTimeout changes
Resolved in Pega Version 8.2.8
Connect Rest services were not timing out at the expected 60 second mark, but were instead running for 120 or even 200 seconds. This bug arose as a result of Apache's refactoring of their HTTPClient in version 4.3. This refactoring split ConnectionTimeout into two variables, ConnectionTimeout and ConnectionRequestTimeout, in order to give users more granular control over client timeout behavior. The implementations of HTTPClient have now been amended so that all HTTP Client configurations set ConnectionRequestTimeout appropriately.

Additional DSS added to handle Apache client-level timeout
Resolved in Pega Version 8.2.8
n Connector rule, the system timed out a connection after 1 hour even after a connection time timeout was configured to be 30 seconds. Apache's refactoring of their HTTPClient in version 4.3 specifies request timeouts in two ways: on the client-level and on the request-level. Client-level timeouts are enforced prior to and during the handshake, whereas request-level timeouts are enforced after the handshake has been made. Previously, RESTConnector.java and ComponentsHTTPClient.java were configured to only set the user-specified timeout on the request, and not on the client. This caused the client-level timeout to default to "0", or an infinite amount of time. In this reported issue, the remote host closed the connection before the handshake had been completed so the connection remained open for several hours. To resolve this, the DSS "ClientLevelHTTPTimeout" has been added to allow specifying a client-level socket timeout, and ComponentsHTTPClient.java and RESTConnector.java have been amended to assign this value to the client. This DSS is set to 0 by default to preserve backwards compatibility.

Check added to minimize Obj-Open-By-Handle error logging
Resolved in Pega Version 8.2.8
When using a Data Type with the "Automatically generate a unique id " option, calling the Save-DataPage method by using the savable data page of the data type finished correctly but showed Obj-Open-By-Handle errors on PegaRules.log. Investigation showed the exception was thrown when running the save plan from DataPageSaverImpl: while attempting to run the save plan, the system does not know whether a parameter (pyGUID in this case) will be required to run the save plan or not, meaning that it can't detect any possible error in DataPageSaverImpl. The implementation instead makes a call to db.open to check if an instance exists and hence logs are thrown. To resolve the error logging, a check has been added: if the save-to class has an autogen key and the savable data page instance doesn't have the autogen key in it, the system will directly call pxCreateRecord. This will avoid a call to db.open to check if instance exists and hence no failed logs will be thrown. This partial change will work only for classes having an autogen key and in cases where the page is trying to create a record by intentionally not passing the key.

Handling added for BIX count mismatch in manifest and extracted CSV data
Resolved in Pega Version 8.2.8
A mismatch in the counts in the manifest file when compared to the data extracted in the CSV files was traced to a corrupted or wrong pzinskey in the source database. If the BLOB is corrupted while extracting to output type and manifest type to CSV, an invalidstream exception was generated and resulted in the manifest file and extracted CSV file total instance count mismatch. This has been resolved by adding handling to balance the counts.

Landing page refresh modified to avoid frequent reloads
Resolved in Pega Version 8.2.8
Approximately every two weeks, clients were able to login but it was not possible to work as the landing page refreshed constantly until all of the nodes were rebooted and the issue was cleared. Investigation indicated the frequent reloads were related to the cacheing of the operator details, and this has been resolved by updating the datapage reload strategy based on 'when' so frequent reloads will be avoided.

Handling added to avoid primary key exception in pxExtractDataWithArgs
Resolved in Pega Version 8.2.8
While running the activity pxExtractDataWithArgs with -c, the "Error while getting the sequenceNumberERROR: duplicate key value violates unique constraint pr_log_pk" occurred if both Parent and Child classes were pointing to different table and extraction started from the child class. In this case, because the Parent and Child classes were pointing to different tables while extracting with the -c option, the class list order caused a primary key constraint violation exception while generating the process sequence number. To resolve this, while adding the classes to the instance map, the order will be changed to parent followed by child classes.

Resolved BIX Extract Summary Status Count mismatch
Resolved in Pega Version 8.2.8
A mismatch was seen between the summary of the Extract Summary Status Count in the Execution History stats versus the logs, for example the execution history saying 98.74% completed while the log says 100% or 100.45% completed. Investigation showed there was mismatch in the query based on the filter value given in the extract rule and the where clause in the query that resulted in an error in calculating percentage in case of any exception. This has been resolved.

PropertyToColumnMap made more robust
Resolved in Pega Version 8.2.8
The DF_ProcessEmails dataflow was intermittently failing with a StageException error. This was traced to schema changes being propagated asynchronously by system pulse, which seem to have caused PropertyToColumnMap to cache stale schema. To resolve this, if the property mapping is not found the first time, the system will make a second attempt to get the mapping. Additional logging has also been added for better diagnostics.

Able to add offer to Change Request after deleting other offer from the landing page
Resolved in Pega Version 8.2.8
A Change Request creation was failing after deleting an offer rule from the revision management landing page. While deleting the offer rule, the activity pyDeleteRuleFromLP is called and pxDeleteRecord API is used to delete the rule. The pyWorkPage is being modified with class Work-ProjectManagement-CheckIn when the pxDeleteRecord activity is executed, but after this, the Change Request creation failed due to the wrong context of the pyWorkPage. This has been resolved by adding Page-New of pyWorkPage conditionally.
