Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

File Dataset wildcards updated for ADM storage
Resolved in Pega Version 8.7
Attempting to access the filepath was failing and an error was seen indicating "Could not obtain lock 'Create repository file pegacloudfilestorage:ADM/Rule-Decision-AdaptiveModel/Data-Decision-Request-Customer". While creating a file name, a lock is generated while checking the file names of existing files. If the file data set has a large number of files, a condition may occur where some threads are unable to save data and an exception is thrown. To resolve this, the wildcard previously used in the file name has been replaced with the Pega node id + thread id + current timestamp. This will ensure all wildcards are unique and there is no need to lock and list existing files.

Case Archive updated to better prune email and attachment metadata
Resolved in Pega Version 8.7
After configuring pyPegaArchiver, pyPegaIndexer and pyPegaPurger to remove old cases, there were no records present in the pr_metadata table but the records related to Data-Corr-Email, Data-WorkAttach-File and Link-Attachment remained. As there is no harm in removing these entries because the system has already copied the reference to these attachments, the entry in pr_metadata can be removed without any issue. With this update, external and shared entries now get removed from pr_metadata table when a purge is performed, however they do not get removed from the target table.

Notification option for change of search nodes removed from Cloud
Resolved in Pega Version 8.2.7
The search landing page for Pega Cloud was displaying a checkbox to enable sending automatic emails if the search node was modified. As the description of the notification 'Notify on change of search host nodes' suggests, this option is to send notifications only when a search host node has been modified(addition/removal) from the search landing page. This is not applicable for the automatic addition/removal of search nodes that happens on starting the node. As the addition/removal of nodes is not allowed from the search landing page on Cloud environments, this option is not applicable for Cloud and the checkbox has now been removed for that environment.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Parameters added to protect font size in HTML to PDF conversion
Resolved in Pega Version 8.2.7
Pega uses the pd4ml external library for HTML to PDF conversion. As part of this, the adjustHTMLWidth API was called to avoid truncation issues, but this resulted in font-sizes not being preserved in the exported document but rather changed as necessary to fit in the PDF. In order to support preserving the font size during export, the pyPDFSettings datatransform will call the protectPhysicalDimensions API along with setHTMLWidth, and avoid calling adjustHTMLWidth. With this change in place, any content width should not be set explicitly to some value as it may lead to truncation if the space is not sufficient. If there is no width set, text will wrap automatically. In case of tables with large number of columns, truncation issues may be seen: to avoid such issues, pass a larger htmlWidth value so that table will be reduced in size and in the rest of the page, font-sizes are preserved.

Index table correctly populates after migration
Resolved in Pega Version 8.7
After creating a product file with work instances, only some records were populating in the index-workpartyuri class through index rule. Investigation showed that if the IDs specified for the Work Range started with the same digits as were seen after the case prefix (e.g. W-1, W-1000, or W-22, W-2201) then only the indexes for cases that start with W-1 or W-22 were included in the export. This was traced to a step in AddPartyIndexWhenCondition where the EstimatedWorkPrefix local variable was calculated: the java step extracted anything that was the same from the start of the To and From range without taking into account the possibility that some digit characters after the "-" could be the same. To improve the accuracy of the prefix estimation, "-\d" will be used to make an educated guess.

Handling added for multi-file upload of duplicated files
Resolved in Pega Version 8.7
Attaching the same file multiple times during a single upload caused some of the duplicated files to not be included. The issue was not seen when attaching the same file multiple times but in different attempts. The exception "Can't continue with file attachment. FileData.xlsx is missing and might have been quarantined by anti-malware software" was logged. This was caused by the files being uploaded without updating filenames to have a unique ID, so multiple files with the same name were overwriting the previous file. This has been resolved by setting the appendUniqueIdToFileName parameter to true in the upload request so each copy of the filename is treated as an individual file.

Resolved tab appearance issues related to resolution support
Resolved in Pega Version 8.2.7
When trying to add multiple tabs on larger screens, once the first row was filled with tabs then new tabs began appearing at the bottom of the layout group. The layout group worked as expected with the tab overflow having the right and left arrows with the dropdown on smaller screens. In addition, @1440px the overflow arrow on the right side was not working correctly, showing as grayed out even though focus was not on the last tab. These issues were traced to taboverflow with add icon not working correctly at certain resolutions. To resolve this, the todisableslide function has been updated to consider add icon width and layoutgroup has been updated to consider parent width.
