Kwcheck

kwcheck is a desktop analysis tool for C/C++, C#, and Java developers using IDEs and text editors that aren't supported by Klocwork in the form of an IDE plug-in. For how-to information, see Getting started with kwcheck for C/C++ and Getting started with kwcheck for Java.

While connected to a base project or any of its streams, performing a local analysis syncs all the defects in the project's base project and all its streams. Also, citing defects locally applies to the base project and all its streams.

General usage

Always place the subcommand directly after the kwcheck command in your command line:

kwcheck <subcommand> [<options>]

You can use an arguments file with kwcheck subcommands. You can create an arguments file to specify your command line arguments. Each argument must be specified on a separate line. If the arguments file contains multibyte characters, the file must be UTF-8 encoded. The usage is:

kwcheck <subcommand> @<arguments-file> 

kwcheck create

Creates local project and project-settings directories for a desktop project; the newly created project does not contain data until it is analyzed or synchronized with the server project.

Usage: Connected desktop

kwcheck create --url http://<klocwork_server_host>:<klocwork_server_port>/<project> [-pd <local_project_dir>] [-sd <local_settings_dir>]

Example

kwcheck create --url http://acme:8074/bigproject

Usage: Standalone desktop

kwcheck create [--license-host <host_name>] [--license-port <port_number>] [-pd <local_project_dir>] [-sd <local_settings_dir>]

Details

By default, the local-project and Klocwork project-settings directories are created in your working directory and are named .kwlp and .kwps. You can specify your own names and locations for these directories with the -pd and -sd options. However, using the default names and locations allows you to limit the scope of your analysis or filter with kwcheck list to your current subdirectory instead of the whole project.

  • .kwlp stores temporary working files and the build specification file.
  • .kwps stores the build specification template (if applicable) and configuration files
Note: To delete your analysis results and settings, delete the .kwlp directory and run kwcheck create again.

Options

Name Short name Description
--build-spec <file>.out -b imports the build specification into the local project. This option is incompatible with build specification template files and build specification files generated by kwshell.
--force-32bit   forces the analysis engine to 32-bit. If you are using old path checkers from pre-2020.3, you have to use this option for the checkers to work
--license-host <host_name>   specify the License Server host name; ignored if --url is used
--license-port <port_number>   specify the License Server port number; ignored if --url is used
--license-provider <license_provider>   specify the name of your license provider; flex or reprise. (not for connected desktop)
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree
--settings-dir <dir> -sd specify name and location of the project settings directory. Default: .kwps in your working directory
--url http://<klocwork_server_host>:<klocwork_server_port>/<server_project>   URL for the project. The arguments identify the project and the Klocwork Server where it's located. Use https:// if a secure Klocwork Server connection has been configured.

kwcheck disable

Disables the specified checkers. Requires permission to change local configuration. When you enable or disable checkers, a file called a user profile (.pconf.xml) is created to store the non-default settings. You can export this file with kwcheck export to share with other users. You can also use the Configuration Editor to disable checkers.

Usage

kwcheck disable <ISSUE.CODE1> <ISSUE.CODE2> [...]

Example

kwcheck disable CL.MLK CWARN.SIGNEDBIT

Details

Separate issue codes with spaces. Issue codes must use upper case. Note that disabling the Header Analysis checkers has no effect for kwcheck or Klocwork Desktop.

Options

Name Short name Description
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree

kwcheck discard

Removes the specified configuration file from your project. Requires permission to change local configuration.

Usage

kwcheck discard [options] <config_file>

Example

kwcheck discard user_metrics.mconf

Details

The types of configuration files you can remove are:

  • build specification (buildspec.txt)
  • build specification template (.tpl)
  • user profile (.pconf.xml)
  • knowledge bases (.kb for C/C++ or .jkb for Java)
  • metric thresholds (.mconf)
  • macro override file (kw_override.h)
Note: When you remove a user profile, Klocwork reverts to the default checker configuration.

Options

Name Short name Description
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree

kwcheck enable

Enables specified checkers. Requires permission to change local configuration. When you enable or disable checkers, a file called a user profile (.pconf.xml) is created to store the non-default settings. You can export this file with kwcheck export to share with other users. You can also use the Configuration Editor to enable checkers.

Usage

kwcheck enable [options] <ISSUE.CODE1> <ISSUE.CODE2> [...]

Example

kwcheck enable CL.MLK CWARN.SIGNEDBIT

Details

Separate issue codes with spaces. Issue codes must use upper case.

Options

Name Short name Description
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree

kwcheck export

Exports the specified configuration file from your project to share with other users. Requires permission to change local configuration. With connected desktop, all configuration settings are pushed to the desktop from the server. If you have permission to change local configuration, you can export local settings so that other users can import them. Local settings take precedence.

Usage

kwcheck export [options] <config_file>

Example

kwcheck export user_metrics.mconf -o /shared/jlee_metrics.mconf

Details

You can export the following configuration files:

  • user profile (.pconf)
  • knowledge bases (.kb for C/C++, .jkb for Java)
  • metric thresholds (.mconf)
  • macro override file (kw_override.h)

Options

Name Short name Description
-o <file>   specify the output file location and name (default: current directory and current file name)
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree

kwcheck import

Imports the specified configuration file into your local project. Requires permission to change local configuration. With connected desktop, all configuration settings are pushed to the desktop from the server. If you have permission to change local configuration, you can export local settings so that other users can import them. Local settings take precedence.

Usage

kwcheck import [options] <file>

Example

kwcheck import /shared/jlee_metrics.mconf

Details

With the exception of knowledge bases, a desktop project can only contain one of each of the following file types:

File type Default extension
build specification .out
knowledge base .kb for C/C++, .jkb for Java
macro override file .h
metric thresholds .mconf
user profile .pconf

To import a file with a non-default extension, specify the --type option.

Filtering out issues

You can specify an external configuration file to filter specific issue types or all issue types for a specific constraint. You must specify the direct name of the macro you want to filter; you cannot use regular expressions to specify macro names. For more information, see Filtering out issues.

Options

Name Short name Description
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree
--type <config_file_type> -t specify file type for files with non-default extensions; allowed arguments are:
  • buildspec or b
  • kb
  • jkb
  • override-file
  • mconf
  • pconf

kwcheck info

Displays local project settings.

Usage

kwcheck info [options] 

Example

kwcheck info -pd new_project

Details

Settings displayed:

  • status.permission: The statuses you are allowed to use when changing issue status. *\:* means that you can change a reported issue to or from any status.
  • klocwork.host: Connected projects only
  • klocwork.project: Connected projects only
  • license.host: For all projects, connected or not
  • license.port: For all projects, connected or not
  • useconf.permission: Whether you have permission to change local configuration, such as enabling or disabling checkers

Options

Name Short name Description
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree

kwcheck list

Filters the issue list by issue number, issue code, status, severity and file.

Usage

kwcheck list [options] [<file_1>] [<file_2>] [...] 

Example

kwcheck list --id 4-9,16-22,77 --issue abr,abv.stack foo.c foo2.cpp

Details

Files must be space delimited, whereas filtering options, such as status, must be comma delimited. Express ranges for severity or issue ID with a hyphen.

By default, kwcheck displays issues:

Running kwcheck list from the directory that contains the .kwlp will list detected issues for the whole project. If your local project directory has the default name (.kwlp) and is located in the source tree, you can filter issues in the current subdirectory instead of the whole project. Simply run kwcheck list from the desired subdirectory. Issues in header files outside the given directory are not listed.

If you run kwcheck list on a project that includes streams, you will see some additional flags in your output, as follows:

JSON:

"inConnected": true/false,

"inOtherStreams": true/false,

XML:

<inOtherStreams>true/false</inOtherStreams>

<inConnected>true/false</inConnected>

inConnected is true if the issue exists directly on the connected stream or project and is not in the "Fixed" state. inOtherStreams is true if the issue exists in any stream in the family tree except for the connected stream. Both flags can be true (for example, the issue exists in both a connected stream and in an additional stream).

Filter options

Name Short name Description
--id <local_issue_ID>   lists issues by issue ID
--id-system <system_ID>   list issues by system ID
--issue <issue_code_1>[,<issue_code_2>...]   list specified issue codes. Issue codes are case insensitive. For a complete list of the issue codes, see C and C++ checker reference or Java checker reference. You can also run kwdtconfeditor to view a list of checkers and their default settings.
--local -l show local issues. The default setting is to show:

  • no issues detected in the integration build analysis
--no-local -L don't show local issues. Use this option, along with the --system option, to list only system issues.
--no-system -Y don't show system issues. This is the default setting (along with --local).
--severity <severity_number>   list issues of the specified severities. Severity is a value between 1 and 4, with one representing the most serious issues and 4 representing the least serious. Separate severities with spaces or use a hyphen for a range:--severity 1,3-4
--status <status_name>|all -s list detected issues of the specified statuses. Use double quotation marks to enclose statuses containing spaces: "fix in next release". Use kwcheck list-statuses for a list of statuses.
--system -y show system issues. kwcheck list --system shows you system issues in addition to the local issues you see by default. kwcheck list --system --no-local shows only system issues.
--taxonomy <taxonomy_name>

kwcheck run

Runs the analysis on a project, subdirectory or file(s).

Usage

kwcheck run [options]

Example

kwcheck run --issue ABR,MLK.MUST --severity 1-3 -F detailed --report project.txt foo.c foo2.cpp

Details

Files must be space delimited, whereas filtering options, such as status, must be comma delimited. Express ranges for severity or issue ID with a hyphen. Running kwcheck run from the directory that contains .kwlp will analyze all source files for the project. For C/C++ projects, if your local project directory has the default name (.kwlp) and is located in the source tree, you can limit the context of the analysis to the current subdirectory. Files from that subdirectory (and from any child directory) will be analyzed. For Java projects, Klocwork analyzing individual files is not recommended because the limited scope of the analysis can cause inaccurate results.

Options

Name Short name Description
--build-spec <file>.out -b imports the build specification into the local project.
Note: Not for kwshell or build specification template users.
--classic   forces Klocwork to use the previous generation (pre-Klocwork 2018) analysis engine. The previous analysis engine only provides partial support for C++11 and C++14.
-F <format>   controls the format of the issue list; possible formats are:
  • detailed - display traceback on all detected issues
  • scriptable - output semi-colon delimited format
  • short - output without issue numbers and absolute path names
  • xml - output in XML format
For more information, see Kwcheck output reference.
--issue <issue_code_1>[,<issue_code_2>...]   list specified issue codes. Issue codes are case insensitive. For a complete list of the issue codes, see C and C++ checker reference or Java checker reference. You can also run kwdtconfeditor to view a list of checkers and their default settings.
--jobs-num <int> | auto -j specify the maximum number of parallel compilation and issue detection processes to run. Specify one of:
  • an integer from 1 to 255
  • auto to set automatic mode. In this mode, the number of compilation jobs will equal the number of available processor cores plus 1.

    For a parallel analysis on one machine, Klocwork recommends you specify the number of processor cores plus 1. Above this number, performance will be degraded.

--license-host <host_name>   specify the License Server host name
Note: The specified host name is used and stored. If the host name changes, use kwcheck set.
--license-port <port_number>   specify the License Server port number.
Note: The specified port number is used and stored. If the port number changes, use kwcheck set.
--local -l show local issues. The default setting is to show:
  • only issues detected in your local project
  • no issues detected in the integration build analysis
--no-local -L don't show local issues. Use this option, along with the --system option, to list only system issues.
--no-system -Y don't show system issues. This is the default setting (along with --local).
--project-dir <dir> -pd specify the name if different from the default name (.kwlp), and/or location if it's outside the source tree
--rebuild -r overrides incremental analysis to run a complete re-analysis on the project
--report <output-file>   specify the issue output file
--severity <severity_number>   list issues of the specified severities. Severity is a value between 1 and 4, with one representing the most serious issues and 4 representing the least serious. Separate severities with spaces or use a hyphen for a range:--severity 1,3-4
--short-log   Optimize and reduce the size of the build log by reporting fewer details.

Note that this option should only be used after the Klocwork build is stable as details necessary for troubleshooting will be suppressed in this mode.

--status <status> -s list detected issues of the specified statuses. Use double quotation marks to enclose statuses containing spaces: "fix in next release". Use kwcheck list-statuses for a list of statuses.
--system -y show system issues. kwcheck run --system shows you system issues in addition to the local issues you see by default. kwcheck run --system --no-local shows only system issues.
--taxonomy <taxonomy_name>  

list detected issues by taxonomy name. For example:

kwcheck list --taxonomy "MISRA C 2012 (C99)"

This shows you only those issues detected by checkers in the MISRA C 2012 C99 taxonomy.

kwcheck set
