Export Polyspace Analysis Results

You can export your analysis results to a tab separated values (TSV) text file, a MATLAB^® table, or to a standard JSON format. Using the exported content, you can:

Generate graphs or statistics about your results that you cannot readily obtain from the user interface by using MATLAB or Microsoft^® Excel^®. For instance, for each Code Prover check type (Division by zero, Overflow), you can calculate how many checks are red, orange, or green.
Integrate the analysis results with other checks you perform on your code.

Export Results to Text File

You can export results to a tab delimited text file (TSV) from the user interface or command line.

The exported text file uses the character encoding on your operating system. If special characters from your comments are not exported correctly in the text file, change the character encoding on your operating system before exporting.

Export Results from the Polyspace Desktop User Interface

Open your analysis results.
Export all results or only a subset of the results.
- To export all results, select Reporting > Export > Export All Results.
- If you want to filter results from your report, use filters on the Results List pane to display only the results that you want to report. Then, when exporting results, select Reporting > Export > Export Currently Displayed Results.
  For more information on filtering, see Filter and Group Results in Polyspace Desktop User Interface.
Select a location to save the text file and click OK.

Note

If you apply a review scope that sets thresholds for code metrics and you export all results, the generated file lists the results for the code metrics as Green (pass) or Red (fail) in the color column (third column). If you do not set thresholds for code metrics, the exported file shows Not Applicable for code metrics results in the color column.

Export Results from the Polyspace Platform User Interface

Open your analysis results.
Export all results or all variable access information.
- To export all results, select Report > Export All Results.
- To export all variable access information, select Report > Export Variable Access. For more information about variable access, see Variable Access in Polyspace Desktop User Interface.
Select a location to save the text file. You can save your file in CSV, JSON, or TSV format by selecting file type All Files (*.*) and manually editing the file extension. Click Save.

Export Results from Command Line

Use the option -format csv with the polyspace-results-export command. For example, to generate a csv file from results file C:\Polyspace_Workspace\myProject\Module_1\BF_Result\ps_results.psbf, run this command:

polyspace-results-export -format csv -results-dir C:\Polyspace_Workspace\myProject\Module_1\BF_Result

Export Results to MATLAB Table

If you write MATLAB scripts to run Polyspace^®, you can read your Polyspace analysis results into a MATLAB table for further processing. See:

Export Results to JSON Format

You can export Polyspace results to a JSON object. The JSON format follows the standard notation provided by the OASIS Static Analysis Results Interchange Format (SARIF).

Use the option -format json-sarif with the polyspace-results-export command. For more information, see polyspace-results-export.

The JSON format contains some additional information such as the checker short name and the full message that accompanies a result. Use the JSON format if you want to use this short name or message. You can also use this format for a more standardized reporting of results. For instance, if you use several static analysis tools and want to report their results in one interface by using a single parsing algorithm, you can export all the results to the standard SARIF JSON format.

View Exported Results

The exported results include the information available on the Results List pane in the desktop user interface or Polyspace Access™ web interface. See:

Note that some Results List column headers might be labeled differently in the exported results file.

Some other differences in presentation between the Results List pane and exported results are listed below.

The TSV file and MATLAB table contain these additional columns compared to the Results List:
- New column — Shows whether a result is new compared to the previous run.
- Key column — The entry in this column is based on the result family, result acronym, and the location of the result in the file. See also Compare Merged Results Using Exported Keys.
- URL column (Polyspace Access results only) — Click the URL to open the corresponding result in the Polyspace Access interface.
The JSON file stores the results as objects contained in a results array. Each object has a list of key-value pairs that store the results information, including whether the result is new compared to the last run ("baselineState") , the result key, and the URL ("hostedViewerUri "). For more on the JSON format see SARIF-v2.1.0.

You cannot identify the location of a Bug Finder result in your source code via the text file. However, you can still parse the file and generate graphs or statistics about your results.

Export Results with a Large Number of Findings

Polyspace does not support the export of more than 500,000 findings at a time. If the number of findings in your analysis results exceeds this upper limit, Polyspace attempts to reduce the number of findings to export by omitting findings in this order:

Omit all code metrics findings.
If the number of findings is still over the threshold, omit all low impact defects (Bug Finder) or green checks (Code Prover).
If the number of findings is still over the threshold, export only the first 500,000 findings.

A project with a large number of findings might indicate a suboptimal analysis configuration. If your analysis produces a large number of findings, modify your configuration to check for a smaller set of high priority defects and coding rule violations. See also Troubleshoot Uploads to Polyspace Access That Exceed Size Limit (Polyspace Access).

Compare Merged Results Using Exported Keys

When you merge exported analysis results from multiple modules that contain common files, you can use the Key and other fields from the exported results to eliminate duplicates. For instance, if you run coding-rule checking on two different modules and merge the results, coding rule violations in common header files appear twice in the results.

To eliminate duplicates, compare the Key and File values of the results. If two results have the same Key and File values, one is a duplicate of the other.

By default, each result key is based on the result family (for instance numerical), result short name (for instance float_ovfl), and the location of the result in the file. To generate more localized keys for results that are located inside a function body, use the -key-mode function-scope option with the polyspace-results-export or the polyspace-report-generator commands. The commands generate keys that are based on the result family, result short name, and the location of the result within the function body. You can then identify duplicates more accurately by also comparing the Function values.

In rare instances, results that have the same key and the same location inside a file or function body might not be duplicates. In those instances you need to compare the results manually, for instance by comparing the result messages in the user interface, to determine whether the results are duplicates or not.

Enable Function Scope for Exported Keys

To enable the function scope for exported keys:

At the Command Line
Enter either of these commands to export locally stored results:
```
polyspace-results-export -results-dir folderPath -key-mode function-scope -format csv
```
or
```
polyspace-report-generator -generate-results-list-file -results-dir folderPath -key-mode function-scope
```
where folderPath is the path of the folder that contains the Polyspace analysis results.
Make sure that you run these commands from a location where you have write permissions, or use option -output-name to specify a location to store the generated file of exported results.
In the Polyspace Desktop User Interface
Create a menu item by going to Tools > Preferences and entering this command on the Tools Menu tab:
```
$POLYSPACE_ROOT\bin\polyspace-results-export.exe -results-dir $RESULT_DIR -key-mode function-scope -format csv -output-name $RESULT_DIR
```
You can then export results by using the menu item you created from Tools > External Tools.
To export results with the default key mode (without function location), use the Reporting > Export menu.

When you export results with the function scope enabled, the key entries for results that are inside a function have a FN prefix.
