What's new in Klocwork 2024.1
Released March 2024
Here are the highlights for Klocwork 2024.1. If you're upgrading Klocwork, see the Limitations for items that might affect your upgrade and usage.
Take advantage of upgrade and migration improvements
You can now:
-
Minimize maintenance and downtime by starting the Validate Server before projects have been migrated. Successful migrations will be available immediately, and failed migrations will be automatically disabled.
-
Apply fixes and remigrate problematic projects without interrupting the use of successfully migrated projects.
-
Save time by migrating individual projects without having to restart the Validate Server.
Manage project states
You can assign project states using the kwadmin command, to indicate whether a project is active, inactive, or unavailable, and whether it is being migrated or deleted. Project states are visible in Validate and the Web API.
In addition, you can assign project states to restrict edit and view access during maintenance operations or backup creation.
Exclude individual projects from migration
To help speed up migration, you can exclude specific projects. Excluded projects will not be migrated and will appear as disabled in the Validate tools. Later, you can migrate and enable excluded projects individually without restarting the Validate server. For details, see Migrate your projects_root directory.
Prioritize migration of specific projects
To prioritize important projects, you can assign a priority list which specifies the order in which projects will be migrated. Projects not included in the list will be migrated in the order of their project id. To learn more, see Migrate your projects_root directory.
Import or duplicate existing projects
You can now import a project from another Validate server even if the project name matches an existing project on the target server. For more information, see Import your projects and server settings.
Explore new capabilities in Validate
You can now:
-
Allow specific users to change an issue's owner but not its status by assigning the permission
change issue owner. -
Benefit from expanded search capabilities with increased support for the use of
*and**wildcard characters in modules.
Preserve license logs for audit purposes in Klocwork and Validate
You can now preserve logs for auditing purposes, by appending the logs to your license server license.report.log file instead of overwriting the file after the server restarts. To learn about the append.license.logging setting, see kwservice.
Analyze projects that were built with Bazel
You can analyze projects built with Bazel by using the kwbazel command on Linux or the --bazel option in kwandroid for Android projects. The kwbazel command supports build integration for C/C++, C#, and Java projects, allowing custom compilation mnemonics handling through configuration. Bazel's virtual_includes are also supported.
Download issue list as CSV
You can now download your list of issues as a CSV file. The CSV download button can be found at the top of the Issues page.
Kwciagent now hides stream issues by default
Starting in this release, kwciagent list is set to --no-stream by default to hide stream issues. To view stream issues, you must set kwciagent list to --stream.
Discontinuation of docs.roguewave.com in 2024

Discontinuation of Klocwork Server installations in release 2023.4
Starting from release 2023.4, Klocwork Server installations have been discontinued. You can transition to a Validate installation, which is designed to provide a more streamlined and integrated experience.
When transitioning from Klocwork to Validate:
Stop your Klocwork instance and back up the projects_root directory.
During Validate install, set the projects_root directory location to your current projects_root directory.
If you are currently using non-default values for ports or license server, be sure to set the same values when you install Validate.
Discontinuation of issue grouping
Starting from Klocwork 2023.3, issue grouping is turned off by default for new projects.
To help avoid issues, turn off issue grouping before you upgrade Klocwork.
