This has been split up into many helper methods that allow derived classes to control more of the export process. Derived types can influence which variables are exported, how materials are handled, and ultimately set various properties in the contract. If the contract has changed then the pipeline gets re-executed. This is an improvement over the former code that too often resulted in pipeline re-executions.

Down in writer plugins, there are various ways that we need to handle data. Some formats can deal with writing their data to a separate file. Other formats need to contain all data in a single file or single object within that file. The export mechanism has been extended so it asks the derived type the proper geometry combination mode based on the type of plot being exported. Writers can get VisIt to combine all data on rank 0, combine like data (label match) on rank 0 into n objects, or do no combining and let each rank get its own chunk of data (the old way). Geometry combination in the writer can simplify many plug-ins that were doing their own geometry combining since they can now use the base class methods.

The database plugin API was extended so it supports reading a license/copyright string from the plugins and passing it back to the clients. The current example of where this is used is in the Export window, which can show the plugin license on export.

XDB plugin support was added to the VisIt svn repo. XDB is a plugin that stores VisIts VTK data into FieldViews XDB format so that FieldView can read and process the extracted data. XDB exports will be used in VisIt at scale and in situ to extract data for FieldView customers. This is the first example of a plugin that is primarily a binary. We had to develop cmake logic to determine compatibility, select the plugin, copy its support libraries in a way suitable to regular VisIt development builds, and ensure that plugins were installed properly when doing make install or make package. 13New/Enhanced Database Plug-insDatabase Plug-inDescriptionOVERFLOWNew proprietary OVERFLOW readerSupercedes VisIt OVERFLOW readerSupports derived variables using OVERFLOW formulationsStructured, multi-block, overset gridXDBNew plug-in containing FieldView extract database (XDB) format writerBinary deployment in open source VisItEnables VisIt/Libsim to directly output XDB files for analysis in FieldViewFV-UNSNew proprietary data readerVolumetric data + boundariesDeveloped for future FieldView-VisIt binary deploymentproof of concept for boundary data
