INC-130304 · Issue 567924

Retry logic added for downloading upgraded rules

Resolved in Pega Version 8.1.9

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.

INC-133202 · Issue 574701

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.

SR-D84364 · Issue 551402

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.

SR-D22505 · Issue 493366

Circumstancing template and definitions assembly modified to avoid calling RD

Resolved in Pega Version 8.4

After deploying a new rollout, errors such as "Only authenticated client may start this activity: RULE-OBJ-ACTIVITY RULE-OBJ-REPORT-DEFINITION" and "You lack access required to execute RULE-OBJ-ACTIVITY RULE-OBJ-REPORT-DEFINITION" appeared. Investigation showed that during an unauthenticated session, executing Report Definitions or accessing database (with securityCheck enabled) are not allowed. When someone wants to use circumstanced rules during the custom authentication process, and if the circumstancing rules are not assembled yet, then assembly of the circumstanced rules triggers the assembly of circumstance template and definitions. During this process the system used Report definition, but since execution of RD is not allowed without authentication the assembly was failing. This has been resolved with two changes: the MergeDefintions activity which is invoked during assembly of CircumstanceTemplate : has replaced the pxRetrieverReportData activity (which invokes RD to fetch circumstances definitions), and the GetAllDefinitionRows activity which is invoked from MergeDefinitions : has replaced Obj-open in step 3.

SR-D24900 · Issue 503875

Security update for RequestMap error logging

Resolved in Pega Version 8.4

In HttpAPI, the RequestMap contains Cookie information. In error conditions, this map gets logged. An update has been made to ensure that the Cookie value is not logged if there is an error.

SR-D27644 · Issue 497614

Uploaded attachments will receive a unique name to prevent overwriting

Resolved in Pega Version 8.4

An issue with an incorrect file being attached to a work object was traced to overlapping processes. When files are uploaded, they are first saved to common HDD directory and then read into memory and deleted from the HDD area. Files will overwrite other file carrying the same name, which is a problem if the first file is not completely uploaded and is waiting in the common directory and some other file with the same name is uploaded on top of it. To resolve this, an update has been made to ensure file names are appended with a unique identifier to distinguish between files carrying the same names and keep them from overwriting each other.

SR-D28083 · Issue 512937

DeleteOrphanStaticContent CacheConfigID populated on node startup

Resolved in Pega Version 8.4

The pzDeleteOrphanStaticContent activity which triggers to clear cache was unable to clear the files in the static content folder and in the database when the files were more than one week old. In order to correctly cleanup old static content, pzAsmCacheConfigID must be populated in py_sys_statusnodes. However, when SystemNodesDAO was introduced to populate pr_sys_statusnodes, pzAsmCacheConfigID was not populated. To resolve this, pzAsmCacheConfigID is now populated on node startup when node information is added to pr_sys_statusnodes.

SR-D28184 · Issue 497168

Verbose debug logging removed from LockUtils

Resolved in Pega Version 8.4

Verbose debug logging that had been added to the "LockUtils" class to print when the lock was acquired or released and include the associated stacktrace has now been removed as it interfered with diagnosing locking issues when threads were getting blocked.
