GBS Versions

The following versions of GBS are supported with GemStone/S 64 Bit version 3.2.12. You must use GBS version 7.6.1 or later for VisualWorks, or 5.4.2 or later for VA Smalltalk with GemStone/S 64 Bit v3.2.12.

VSD Version

The GemStone/S 64 Bit v3.2.12 distribution includes VSD version 5.1. The previous version of GemStone/S 64 Bit, v3.2.11, included VSD v5.0.1.

Changes between v5.0.1 and v5.1 include:

• Ability to select multiple files to load, and to load these files either independently or appended.
• Title bar now includes VSD version.
• Record the last used file directory over VSD restart
• load very large (10GB) data files on Windows
• Several other minor fixes and changes.

For more details, see the Release Notes for VSD v5.1.

Updated SSL libraries

The version of OpenSSL used by GemStone/S 64 Bit v3.2.7 has been updated to 1.0.2e.

Improved performance for listInstancesInPageOrder

The methods:

listInstancesInPageOrder:toFile: 

listInstancesInPageOrder:toFile:withMaxThreads:maxCpuUsage: 

fastListInstancesInPageOrder:toFile: 

performed poorly in v3.x compared to 2.x, as a result of the way multi-threaded scans work. This has been corrected; now, the list of instances is generated into hidden set 1, which is then written out in page order after the multi-threaded list instances completes.

In addition to the changes in the listInstancesInPageOrder* methods, supporting methods to perform the substeps have been enhanced or added.

The following methods, which previously took a single Class, can now be passed either a Class or an array of Classes:

Repository>>listInstancesHiddenSet:withMaxThreads:maxCpuUsage:

Repository>>listInstancesToHiddenSet:

Repository>>fastListInstancesToHiddenSet:

The following methods have been added:

System>>writeHiddenSet:toPageOrderFile:maxBufferSizeMb: 

System>>compareHiddenSet:to:

For details, see method comments in the image.

System configurationAt: methods unnecessarily expensive on Linux

The C code supporting System _configurationAt:isStone:kind: made expensive calls to fetch host information using get_nprocs(). This affected performance of configurationAt:, stone and gemConfigurationAt:, stone and gemVersionAt:, as well as any other senders of _configurationAt:isStone:kind:

This information is normally static; it is now cached after the first read. (#45826)

Index remove errored with autoCommit true in manual transaction mode

The IndexManager performs special handling when autoCommit is true and the system is in manual transaction mode. There were cases where the handling of transaction state resulted in an unnecessary attempt to commit when not in transaction. (#45896)

Netldi may have lingering defunct child processes

There are conditions, observed on Linux, in which the Netldi child processes (such as Gems) are not reaped properly. (#45888)

Veritas VxFS on AIX not recognized as local file system

GemStone operations that requires a local file system disk could fail if the file was on a veritas file system on AIX; this was not recognized as a local filesystem. (#45869)

Shadow pages may remain after reclaimAll

After a reclaimAll, there should be no shadowed pages; a small number were remaining. (#45819)

Added cache statistics

The following cache statistics have been added:

ObjectsReadDuringTraversal
The portion of ObjectsRead that occurred during fetch and store traversals.

OtDataPageReadsDuringTraversal
The portion of DataPageReads+ObjectTablePageReads that occurred during fetch and store traversals.
