SNAP Core Change Log

Version 1.0.2 - Released 11/19/08:

• The Model Notes viewer was updated to include support for Model Options and "root components" (such as RELAP5 Reactor kinetics).
• The ModelEditor selection "rubber-band painting" was updated to improve its performance under OS X and Windows with Java JRE 1.6.0.
• The "Import View Template" operation was updated to include the "Replace Annotations" and "Replace Display Beans" options.
• An issue was resolved where changing a model's view lock did not carry through to its unopened views.
• An issue was resolved where closing the last open model did not remove its model panel from the Property View.
• The viewable files listing in Job Status and the Console Dialog was updated to list only files that are actually available and to display the size and last modified date of each file.
• An "Editing Restart" indicator icon was added to the model accordion node.
• The Animation plug-in's Generic range was updated to include a Segment Style (stepped, gradient and the new Enumeration). The enumeration segment style can be used to display values such as flow regime which are integers presented as floating point values.
• An issue was resolved that prevented a model's "model panel" from being closed when closing the last open model.
• An issue was resolved that prevented assigning user numerics to real values for plug-ins using the legacy numerics framework.
• The opening logic for MED files has been modified: selecting a file that has already been opened in the ModelEditor will now select that model in the Navigator instead of opening a second copy of the model. In addition, attempting to Save As over the save file of another open model is denied with an error message.
• The shared python "Functions" for the new numerics were updated to handle all values in the current model units.
• Executing user defined functions will now automatically update the property views, 2D views, and ASCII views that are currently open.
• The flow indicator display bean was modified to allow specifying line thickness and arrow size.
• The editor for selecting the font used when displaying ranges inside a 2D view was modified to allow any font size.

Version 1.0.1 - Released 10/24/08:

• Core support for the "Component Sub-Systems" feature was added. Component sub-systems provide a convenient means to organize model components. This permits components to be grouped into sub-systems (such as a steam generator) which can then be treated as a single object within SNAP. Note that support for this feature is must be implemented by the individual plug-ins. Limited support, (copy/paste, show ASCII, diff, and create/add to view operations), has been implemented for the TRACE and RELAP5 plug-ins.
• Undo/redo buttons were added to the Model Notes editor.
• An issue was resolved that caused the CTRL-TAB keyboard shortcut for switching between models to become unresponsive after closing all but one model.
• The Open MED button, and menu item, and command line parameters were updated to allow any number of models to be specified at once.
• An issue was resolved in the Properties View Real editor that prevented the pop-up menu from functioning properly.
• An issue was resolved in the Properties View that could prevent Real values from being multi-edited.
• The table editors for real values were updated to display the name and the current value of the shared numeric real in the table cell (if one is selected).
• An issue was resolved that prevented the Configuration Tool from displaying more than the first connection in the "Show Server Status" dialog.
• Copy to clipboard options were added to the View's Export image menus. These options allow the current perspective and the entire view to be exported to the clipboard for subsequent pasting into word processing applications such as MS Word.

Version 1.0.0 - Released 9/19/08:

• Session support was added to the model editor. The list of open models is now saved when the ModelEditor is closed. When the ModelEditor is started, the previously open models are either reopened, ignored, or the user can be prompted to decide what to do. This behavior is controlled with the new "Restore Session" property of the ModelEditor preferences.
• An issue was resolved in the Component Differencing Utility that prevented the export of comparisons between different "versions" of the same component.
• Improvements were made to the syntax coloring and line gap algorithms for the Component Difference Viewer.
• The selected view is now preserved when saving and opening a model.
• Tool tips were added to the window mode buttons located on the main toolbar.
• An issue was resolved that prevented the name attribute from appearing in the 2D view Property View.
• The Acrobat Reader launch tool was updated to work under 32 and 64 bit Windows architecture.
• The Create Views dialog now remembers the selected categories for view creation. Note that views are now automatically built when importing the model if the "do not show" check-box was selected.
• A modification was made to the animation plug-in to eliminate an extraneous separator which was included in the model popup menu.
• Undo/Redo buttons were added to the Model Note viewer.

Version 0.28.0 - Released 9/4/08:

• The ModelEditor has undergone a number of significant user-interface improvements for version 0.28.0 including a new Navigator, a component differencing utility, and a new Numerics package. See What's new in 0.28.0 for a detailed look at these changes.
• Support was added for Attribute Level Documentation references. This means that each attribute in a model can refer to any number of model notes. Note that although the CAFEAN core now provides this support, each plug-in must also be modified before attribute level references will be available for that plug-in.
• The ModelEditor Undo/Redo system was updated to handle each open model separately. The undo/redo buttons will now only undo and redo changes made to the contents of the model currently selected in the Navigator.
• The underlying implementation of the ModelEditor Properties View was rewritten to allow automated testing tools to more easily interact with property editors. Its appearance and behavior was modified only slightly as a result of this change.
• Components displayed in the Navigator can now be added to a 2D View via "Drag-n-Drop" of their Navigator nodes.
• The ModelEditor window placement logic for child windows was updated to more correctly handle windows that appear outside the bounds of the current desktop. This update includes handling of multiple monitors and swapping back and forth between single and multiple monitor setups.
• Several minor message display issues were resolved in the Model Error Report Dialog.
• The 2D View Zoom and Pan tools were updated to be available in locked views.
• An issue was resolved in the Playback Controls that occasionally caused the refresh button to repaint in an incorrect location when placed in a view set to zoom other than 100%.

• The animation plug-in was updated to disable editiing the minimum and maximum times for slaved data sources.
• An issue was resolved that prevented slaved data sources from being properly initialized when first connecting to an animation mask.
• The general range bean was modified to resolve an issue repainting dynamic ranges when the min and max values are very close to each other.
• The range bean was updated to properly handle switching from dynamic to fixed data ranges in situations where the calculated minimum and maximum values are nearly the same.
• The logic that controls preserving the current max and min values was modified to select a range of values when the current max and min values are the same.

Version 0.25.0 - Released 9/17/06:

• The SNAP runtime system has undergone a major overhaul:
  • The Calculation Server was updated to include support for multiple Root Folders (with sub-folders) that can contain any number of jobs. These Root Folders can be mounted in Job Status, the Animation plug-in's source run selector or the submit dialog's folder selector by selecting the "Mount Root Folder" item from the right-click pop-up menu of the local Calculation Server node ("localhost"). These folders can be un-mounted by selecting the "Unmount" item from their right-click pop-up menu. Sub-folders can be created by selecting the parent folder and selecting the "Create Folder" item from the right-click pop-up menu.
  • The submit dialog was updated to include remote submission capability and restart job selection capability. In addition, the local restart file selection was updated to allow selecting a local file to submit as the restart file for a remote job.
  • Optional remote connection capability (disabled by default) was added to the SNAP client applications to allow access to remote Calculation Servers for submission of jobs and animation of the results.
  • Jobs managed by the Calculation Server are no longer loaded and processed at startup. Instead, the calculation job files (CJF) that are stored with each job are parsed on-demand and released from memory until needed.
  • Support for sequences of restart jobs was added to the job queue. This allows a sequence of restarts to be submitted before the preceding jobs have started so long as those jobs have been submitted.
  • Note that with this update, existing submitted jobs will not be automatically available as jobs in the Calculation Server. The data files produced under earlier versions of SNAP must be selected directly to be used by animation masks.

• An issue was resolved in View component that prevented the View from properly redrawing when the "Show Connection Points" property was  changed.
• A "Maximum Log Size" preference was added to the Calculation Server configuration to control how large the log file can become before it is rolled to the next file. Note that a total of 10 files are created and these file names reused as the log is rolled over.
• An issue was resolved in the undo process for deleting components that could cause the process to fail after repeated undo.
• An issue was resolved that prevented the "Terminate Job" feature in the Console dialog and Job Status from updating the job's status to "Completed".

Version 0.24.2 - Released 7/21/06:

• An issue was resolved in the ModelEditor batch interpreter that would cause user defined numeric references from being lost when saving a file in batch mode.
• The Text Annotation resizing logic was updated to more correctly determine the size of the rendered string.
• A Preserve Ratio checkbox was added to the "Scale Drawings" dialog that locks the length and width scale factors to the same value.
• An issue was resolved that could cause a boolean editor (yes/no, true/false, on/off) to continuously redraw itself.
• An issue was resolved in the Animation plug-in that prevented newly added beans from being properly animated without disconnecting and reconnecting the animation.
• An issue was resolved on Windows that would prevent the calculation server from shutting down if any client applications were running.
• The Start Server Automatically preference was added to the Calculation Server section of the configuration tool. When activated, the Start Server Automatically preference will enable the local server to startup when needed by local client applications. When not activated, the user will be prompted to startup the server instead. Client applications are considered local only if they are running on the same computer as the server (referred to as "localhost") and running as the same user as the server.
  
  This property will enable the local server to startup automatically:
  
  • when submitting a job
  • when browsing the local server via Job Status
  • when selecting a run for an animation from the local server
  • when connecting an animation to the local server
  
  Activating the Start Server Automatically preference enables the Server Idle Timeout preference. This is the maximum amount of time (in minutes) that the Calculation Server will stay active while no clients are connected. Specifying 0 for this value will prevent the server from shutting down automatically. Note that the Calculation Server must be restarted for this value to take effect.
  
  
• Remote calculation server connection capability was added. This feature is controlled by the Allow Remote Connections property and defaults to No. Note: This feature is only supported under Java version 1.5 or above.
  
  To allow remote connections from other users, first change Allow Remote Connections property to Yes and restart the calculation server. Then, export the server's public key to a convenient location by selecting the Export Public Key item from the File menu. This key can then be transferred to those users who require access to the server.
  
  To connect remotely to another user's calculation server, first open Job Status. Select the Add Server item from the File menu. Enter the server's host name or IP address in the Server Host Name field and their calculation server port in the Server Port field. Then, select the Server Key File received from the remote user that started the calculation server. After pressing OK, the remote server will appear in the server list in Job Status and in the Animation plug-in's run selector.

Version 0.24.1 - Released 6/8/06:

• "One Touch Expand" buttons were added to the divider bar between the Navigator and Views tabs. These buttons can be used to completely hide the Navigator or the currently open Views by clicking the appropriate left or right facing arrow button.
• An issue was resolved in the Executables portion of the Configuration Tool that caused the "Supports Interactive Execution" and "Defaults to Interactive Execution" properties to be reversed.
• An issue was resolved in the submit dialog that would prevent the last selected executable from being used as the default for the next submit.
• Undo capability was added for the "Add to View" feature available for component and Category nodes in the Navigator.
• Logic was added to many of the component selectors (i.e. the blue S) that will ensure that the row containing the currently selected component will be visible in the selector dialog when it is opened.
• An issue was resolved in the Property View that would sometimes remove the last character from property tooltips.

Version 0.24.0 - Released 4/27/06:

• Resolved an issue that prevented parametric export using a temperature as the iterative constant. 
• The editor for modifying the size of connection handles was modified to limit the range of acceptable values. 
• Job Status was updated to more accurately display the dates and times included in the job table. 
• Modified the model import and load routines for every plug-in to cancel correctly if the cancel button is pressed during an import or a load. 
• An issue was resolved in the Configuration Tool that would prevent the calculation server status from being properly reported. 
• An issue was resolved in the Configuration Tool that prevented the "jEdit Executable" property from being saved. 
• A performance issue was resolved in the Calculation Server that could cause completed runs to be considered idle after 30 minutes even when the runs are currently being accessed.
