Date Range changes

Could this be under minor?

We have improved Date Ranges and fixed up some issues with their implementation. This will change results for a number of users, so we have implemented a Scenario Option to turn on the new Date Ranges algorithm. 

...

In a later Beta release, we will implement a utility to convert across while keeping results consistent as much as possible along with user interface improvements to help users understand Date Ranges better.

Results Streaming

Results can now be streamed to files on disk rather than stored in memory. This is to prevent memory issues with large runs.  Results streaming is off by default, however, it can be turned on in Project Options:

        -i, --input[optional]... Input file to read timeseries from. All standard TIME timeseries formats are supported.

        -o, --output[optional]... Output file to save timeseries to. The extension selects the output format based on the standard TIME I/O formats. A directory of the name specified will be created if the format only supports a single timeseries.      
Example: -o "output.res.csv" for Source Results CSV or -o "output.sdb" for SourceDB etc.                                                                                                                                                                     
                                                                                                                                                                                                                                                               
        -k, --key[optional]... Key of a timeseries to output. This can appear multiple times. If no keys are specified then all timeseries will be exported. Use the '--list' option to list timeseries in the input file. The DisplayName is used as the key.
Example: -k "someResult" -k "someOtherResult"                                                                                                                                                                                                                
                                                                                                                                                                                                                                                               
        -q, --query[optional]... SourceDB filter query. Use the '--list' option to list timeseries in the input file together with possible MetadataKeys to filter on.                                                                                       
Example: -q "WaterFeatureType=Storage" -q "ElementName=Storage Volume"                                                                                                                                                                                       
                                                                                                                                                                                                                                                               
        --startTime, --st[optional]... Start time for extracting partial results. If not specified the start of the input timeseries is used.                                                                                                                
Example: --st 1/1/2011                                                                                                                                                                                                                                       
                                                                                                                                                                                                                                                               
        --endTime, --et[optional]... End time for extracting partial results. If not specified the end of the input timeseries is used.                                                                                                                      
Example: --et 31/12/2011                                                                                                                                                                                                                                     
                                                                                                                                                                                                                                                               
        -l, --list[optional]... List the timeseries and metadata contained in the input timeseries file. Standard output may be redirected to a '.json' file.                                                                                                
                                                                                                                                                                                                                                                               
        -a, --addOrReplace[optional]... Add input timeseries to an existing output SourceDb (.sdb) file. Existing timeseries with matching metadata will be replaced. Only supported for SourceDb output files.                                              
Example: --addOrReplace                                                                                                                                                                                                                                      
                                                                                                                                                                                                                                                               
        -f, --force[optional]... Don't prompt for confirmation when overwriting an existing file.

Performance improvements for the command line and Service interface

We have done some work to improve the performance of the command line, less memory (RAM) is now used during a run.  Run times have been reduced in the command line.

The command line now has additional options for results saving:

--resultsOutputMode

There are three modes currently available:

  1. NoOutput - Does not save results anywhere, hence does not fetch results either. Can be used where the result data files are ignored. E.g. in tests, or where a plugin gives a different pathway to results. This improves performance when using automatic exporting tools such as Scenario Options: Simulation results or Simulation Log which automatically exports results after each run to a specific location. 
  2. ClientNamedFormat- Results fetched to client, saved to output file from there, in a format based on output file extension. The data is transferred back to the client and saved (current behaviour).
  3. ServerNamedFormat - Results saved to output file directly from server, in a format based on output file extension. Does not fetch results to client. This "server side" save is more efficient. Default for InProcess mode, since "server side" is local here. Can be used in Client mode, assuming the end user has access to the path provided to the server e.g. a network drive.

New Version Number system

We have changed the version number system to help users understand when they need a new version of Source to open projects.  The previous database version was a letter that wasn't in the version number.

You can now freeze columns and drag columns to reorder the columns in the Allocation table within resource assessment:

Results Streaming

Results can now be streamed to files on disk rather than stored in memory. This is to prevent memory issues with large runs.  Results streaming is off by default, however, it can be turned on in Project Options:
