Migrate Results from Polyspace Metrics to Polyspace Access

If you use Polyspace^® Metrics to store results and monitor the quality of your source code, you can transfer those results to Polyspace Access.

The Polyspace Access Dashboard perspective offers a web interface with navigation between projects and categories of results. From the Project Overview dashboard, view aggregated statistics for all your projects or drill down to view results details by category or file. For each family of findings, open an additional dashboard to see details. After you narrow down the set of findings that you want to address, open them in the Review perspective to start reviewing individual results.

Note

The Review perspective is only available for analysis results generated with a Polyspace product version R2019a or later. To review R2018b or earlier results that you migrated to Polyspace Access, see Open or Export Results from Polyspace Access (Polyspace Access).

You can also review results from Polyspace Access by opening them in the Polyspace desktop interface. You do not need to download a local copy of Polyspace Access results to view those results in the desktop interface. The edits that you make to the results are saved directly in Polyspace Access and enable you to perform collaborative reviews.

Requirements for Migration

The transfer of results from the Metrics repository to the Polyspace Access database requires the polyspace-access binary. This binary is available under the polyspaceroot/polyspace/bin folder with a Polyspace installation. polyspaceroot is the Polyspace product installation folder, for instance C:\Program Files\Polyspace Server\2019a.

For syntax and examples, see polyspace-access (Polyspace Access).

Migration of Results

To migrate results from Polyspace Metrics to Polyspace Access, follow these steps. You must be logged in to your Metrics server to complete this operation.

Identify the Metrics results repository location. The Polyspace Metrics results are stored in the results-repository folder at that location.
To view the path to this location, from the desktop interface, go to Tools > Metrics Server Settings. Or, at the command line, run the command psqueue-check-config.
By default, results are stored under C:\Users\username\AppData\Roaming\Polyspace_RLDatas\results-repository on Windows^® and /home/username/.polyspace/results-repository on Linux^®. username is your computer login user name.

Generate migration scripts.

Once you identify the folder of the repository from which you want to transfer results, define a migration strategy. You can choose to transfer all your projects or you can narrow down the scope of the transfer to a specific set of projects.

Specify a set of projects with the options listed in this table.

Option	Description
`-max-project-runs int`	Number of most recent analysis runs you want to migrate for each project. For instance, to migrate only the last two analysis runs of a project, specify 2.
`-project-date-after YYYY[-MM[-DD]]`	Only migrate results that were uploaded to Polyspace Metrics on or after the specified date.
`-product productName`	Product used to analyze and produce project findings, specified as `bug-finder`, `code-prover`, or `polyspace-ada`.
`-analysis-mode mode`	Analysis mode used to generate project findings, specified as `integration` or `unit-by-unit`.

For example, to transfer only Polyspace Bug Finder™ analysis results that you uploaded to Polyspace Metrics on or after June 2017, use this command:

polyspace-access -generate-migration-commands ^
C:\Users\username\AppData\Roaming\Polyspace_RLDatas\results-repository ^
-output-folder-path C:\Polyspace_Workspace\Migrate^
-project-date-after 2017-06^
-product bug-finder

The command outputs a migration script file for each project stored in C:\Users\username\AppData\Roaming\Polyspace_RLDatas\results-repository that matches the specified product and date. The migration scripts are stored under C:\Polyspace_Workspace\Migrate.

Before you continue, you can optionally open the migration scripts in a text editor and modify the -project or -parent-project parameters. The parameters correspond to the name of the project and the folder under which it is stored in Polyspace Access, respectively.

Migrate the projects.
After you generate the migration scripts, to transfer all the selected projects use those scripts with this migration command :
```
polyspace-access -host hostName -port port  ^
-migrate -option-file-path ^
C:\Polyspace_Workspace\Migrate
```
The command looks for migration scripts under C:\Polyspace_Workspace\Migrate and uploads the results to the Polyspace Access instance that you specify with hostName. Enter your Polyspace Access user name and password at the prompt.
hostName and port correspond to the host name and port number you specify in the URL of the Polyspace Access interface, for example https://hostName:port/metrics/index.html. If you are unsure about which host name and port number to use, contact your Polyspace Access administrator. Depending on your configuration, you might also need to specify the -protocol option in the migration command.
During the execution of a migration script, the command generates a temporary STARTED file. After each successful execution of a migration script, the command deletes the STARTED file and generates a corresponding DONE file in the same folder as the script. For example, the command generates foo.started during the execution of foo.cmd, and then foo.done once foo.cmd is done. Do not delete these DONE files until you have completed your migration from Metrics to Access.
Depending on the amount of data that you are transferring and on your network configuration, the migration might take a long time. You can interrupt the transfer, and then continue from where you left off at a later time. To stop the transfer, press CTRL+C. To restart the transfer:
1. Go to the folder where you store the migration scripts and open the STARTED file in a text editor. The file might be in a subfolder of the migration scripts folder.
2. Follow the instructions in the file, then reuse the same migration command that you used when you started the migration. The command skips projects that uploaded successfully.

If a project migration fails, go to the migration script folder. See the FAILED file for more information.

Differences in SQO Between Polyspace Metrics and Polyspace Access

After you migrate your projects from Polyspace Metrics to Polyspace Access, you might notice differences when you examine your code quality against Evaluate Polyspace Code Prover Results Against Software Quality Objectives.

The difference is due to the way Polyspace Metrics and Polyspace Access calculate the thresholds for the quality objectives. Polyspace Metrics looks at individual files to determine whether your code achieves a given SQO threshold. For instance, if file foo.c does not achieve threshold SQO2, then the whole project does not achieve that threshold.

Polyspace Access looks at the whole project to determine whether your source code meets a given SQO threshold. Even if file foo.c does not achieve the threshold, the whole project can still meet the specified quality objective threshold.
