initial a klocwork analysis

sample code

  • capture build settings

    $ kwinject --output "<.out_path>" <original build command>
    • i.e.:
      $ kwinject --output "~/npp/npp.out" devenv "~/npp/PowerEditor/visual.net/notepadPlus.sln" /Rebuild

  • run an analysis using the build spec

    $ kwbuildproject --url "<kw_url:kw_port>/<project_name>" \
                 --tables-directory "<table_path>" \
                 "<.out_path>"
    • i.e.:
      $ kwbuildproject --url "http://klocwork.domain.com/NotepadPlusPlus" --tables-directory "~/npp/npp_tables" "~/npp/npp.out"

  • load the database

    $ kwadmin --url "<kw_url:kw_port>" \
          load "<project_name>" \
          "<table_path>"

    • i.e.:

      $ kwadmin --url "http://klocwork.domain.com" load "NotepadPlusPlus" "~/npp/npp_tables"

    • debug for authentication issue

      $ kwadmin --debug --url <Klocwork server url> list-projects
      • logout via
        $ kwauth --log-out

full build analysis

sample code

  • re-create the build spec

    $ kwinject --output "~/kw.out" <regular command line>
    • i.e.
      $ kwinject --output "~/npp/npp.out" devenv "~/npp/PowerEditor/visual.net/notepadPlus.sln" /Rebuild

  • force a full analysis

    $ kwbuildproject --url "<kw_url:kw_port>/<project_name>" \
                 --tables-directory "<table_path>" \
                 --force "<.out file>"
    • i.e.:
      $ kwbuildproject --url "http://klocwork.domain.com/NotepadPlusPlus" --tables-directory "~/npp/npp_tables" --force "~/npp/npp.out"

  • load the result

    $ kwadmin --url "<kw_url:kw_port>" \
          load "<project_name>" \
          "<table_path>"
    • i.e.:
      $ kwadmin --url http://klocwork.domain.com/ load NotepadPlusPlus "~/npp/npp_tables"

incremental build analysis

sample code

  • update the build settings

    • i.e.:
      $ kwinject --update "~/npp/npp.out" devenv "~/npp/PowerEditor/visual.net/notepadPlus.sln" /Build

  • execute the incremental analysis

    $ kwbuildproject --url "<kw_url:kw_port>/<project_name>" \
                 --tables-directory "<table_path>" \
                 --incremental "<table_path>"
    • i.e.:
      $ kwbuildproject --url "http://klocwork.domain.com/NotepadPlusPlus" --tables-directory "~/npp/npp_tables" --incremental "~/npp/npp_tables"

  • load the result

    $ kwadmin --url "<kw_url:kw_port>" \
          load "<project_name>" \
          "<table_path>"
    • i.e.:
      $ kwadmin --url "http://klocwork.domain.com" load NotepadPlusPlus "~/npp/npp_tables"

load result from both windows and linux

sample code kwbuildproject

  • create an integration project on kw server via command line

    $ kwadmin --url "<kw_url:kw_port>" \
          create-project "<project_name>"
    • i.e.:
      $ kwadmin --url http://klocwork.domain.com create-project NotepadPlusPlus

  • capture build settings on linux machine

    $ kwinject --output "<.out_path>" <original build command>
    • i.e.:
      $ kwinject --output "~/npp/npp.out" make

  • run an analysis using the build spec on linux

    $ kwbuildproject --url "<kw_url:kw_port>/<project_name>" \
                [--project "<project_name>"]
                 --tables-directory "<table_path>" \
                 "<.out_path>"
    • i.e.:

    • load multiple specification
      $ kwbuildproject --tables-directory <dir> \
                 [--url http://<klocwork_server_host>:<klocwork_server_port>/<server_project>] \
                 [<other_options>] \
                 <build_specification_1> [<build_specification_2>...]

  • load the database on windows

    $ kwadmin --url "<kw_url:kw_port>" \
          load "<project_name>" \
          "<table_path>"
    • i.e.:
      $ kwadmin --url "http://klocwork.domain.com/NotepadPlusPlus" \
          load NotepadPlusPlus \
          "~/npp/npp_tables"

using kwwrap plus kwinject to generate a build specification

reference:

Note: For distributed builds, you must run the following procedure on all build machines and merge the resultant build trace files.

  1. inserting the kwwrap command line before your compiler and linker names

    CC = gcc

    convert to

    CC = kwwrap -o <path_to_kwwrap_trace_file> gcc
// or
CC = kwwrap -o <path_to_kwwrap_trace_file> $(command -v gcc)

    or via creating wrapper scripts

  2. execute the original build command

  3. Convert the build trace into a build specification with kwinject
    $ kwinject --trace-in <path_to_kwwrap_trace_file> \
          --output <path_to_kwinject_output_file>
    • i.e.:
      $ kwinject --trace-in C:/temp/kwwrap.trace \
          --output C:/Klocwork/temp/kwinject.out

when editing the makefile is not an option

i.e.: is /temp/kwwrap.trace

using environment variables

  1. create environment variables

    $ LDSHARED="kwwrap -o /temp/kwwrap.trace $(command -v gcc)"
$ CC="kwwrap -o /temp/kwwrap.trace $(command -v gcc)"
$ C++="kwwrap -o /temp/kwwrap.trace $(command -v g++)"
$ CMAKE="kwwrap -o /temp/kwwrap.trace $(command -v cmake)"
$ AR="kwwrap -o /temp/kwwrap.trace $(command -v ar) rc"
$ export CC C++ CMAKE AR LDSHARED

  2. build with original command

    $ cmake

  3. use kwwrap with CMake and generate the trace

    $ kwinject --trace-in /temp/kwwrap.trace --output kwinject.out

using wrapper scripts

  1. creating wrapper scripts

    $ echo "kwwrap -r -o <path_to_kwwrap_trace_file> $(command -v gcc)" > $HOME/.hook/gcc
$ echo "kwwrap -r -o <path_to_kwwrap_trace_file> $(command -v g++)" > $HOME/.hook/g++
$ echo "kwwrap -r -o <path_to_kwwrap_trace_file> $(command -v cmake)" > $HOME/.hook/cmake
$ chmod +x $HOME/.hook/*

  2. setup environment variables

    $ export KWWRAP_HOOKS_DIR="$HOME/.hook"
$ export PATH=${KWWRAP_HOOKS_DIR}:${PATH}

  3. build with original command

    $ cmake # the original command

  4. use kwwrap with CMake and generate the trace

    $ kwinject --trace-in /temp/kwwrap.trace --output kwinject.out

authentication

[!TIP] references:

  • Authentication using the ltoken
    Failing authentication if host name is not found
    You can enable kwauth to fail authentication in the case where the server host name was not found in the certificate CN or Subject Alternative Name by setting the verifyCertificate option to true. Enabling this results in the following error message if the host name cannot be found: 
    Unable to authenticate using SSL with <url>
    To set this value to true, create a 'client_config.xml' file in your {client_tools_install_folder}\config\ folder (if it does not already exist). The file must contain the following:
    <?xml version="1.0" encoding="UTF-8"?>
 <params>
   <host resolveHost="false" verifyCertificate="true"/>
 </params>
    Note that setting resolveHost="false" is not mandatory, but doing so can prevent the Klocwork Server from resolving the wrong FQDN as the Server will use whatever host you specify in a remote server URL.

ltoken is used to authenticate users with tools such as kwbuildproject:

  • Windows:C:\Users\.klocwork\ltoken
  • Unix:~/.klocwork/ltoken
  • Mac:~/.klocwork/ltoken If there is no ltoken file in your .klocwork directory, run kwauth to generate the file.

using a secure klocwork server connection

[!TIP] for klocwork 2020.4 Build 20.4.0.81

  • Create a self-signed keystore file

    # from <server_install>, run the following command:
# The keystore is saved into the Tomcat config directory at <projects_root>/tomcat/conf.
$ _jvm/bin/keytool -genkeypair -alias tomcat \
                   -keyalg RSA \
                   -keystore <projects_root>/tomcat/conf/.keystore \
                   -dname "cn=<KlocworkServer_hostname>, ou=<your_organizational_unit>,o=<your_organization>" \
                   -keypass changeit \
                   -storepass changeit

# i.e.:
$ _jvm/bin/keytool -genkeypair -alias tomcat \
                   -keyalg RSA \
                   -keystore <projects_root>/tomcat/conf/.keystore \
                   -dname "cn=testserver.klocwork.com, ou=Development, o=Klocwork" \
                   -keypass changeit \
                   -storepass changeit

  • Configure the Klocwork Server to use SSL (manually)

    
$ grep klocwork.protocol <projects_root>/config/admin.conf
- klocwork.protocol=http
+ klocwork.protocol=https

$ grep Connector <projects_root>/tomcat/conf/server.template
-  <Connector port="$PORT" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="64" minSpareThreads="20" redirectPort="8443" acceptCount="200" connectionTimeout="20000" URIEncoding="UTF-8" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla,traviata" compressableMimeType="text/html,text/xml,text/javascript" maxPostSize="-1" />
+  <Connector port="$PORT" maxthreads="4-" minSpareThreads="20" maxSpareThreads="40" enableLooksups="false" redirectPort="8443" acceptCount="50" debug="0" connectionTimeout="20000" compression="on" compressionMinSize="2048" noCompressionUserAgents=".*MSIE.*,gozilla,traviata" compressableMimeType="text/html,text/xml" maxPostSize="0" />

  • restart klocwork service

    [!TIP|label:see also:]

    $ kwservice --projects-root <projects_root> stop
$ kwservice --projects-root <projects_root> start

# or
$ kwservice --projects-root <projects_root> restart klocwork

  • verify

    $ kwadmin --ssl --host klocwork.example.com -port 443 list-projects
# same as
$ kwadmin --url https://klocwork.example.com:443 list-projects

  • disabling the ssl connection

    [!NOTE]

    • Simple bind failed error when trying to connect to Active Directory
      simple bind failed: ad.hostname.com:636

    1. import the ldap server public certificate directly into the klocwork keystore

      # location
<path_to_JVM_install>\_jvm\lib\security\cacerts

    2. ask your LDAP administrator to set this extension of your LDAP server certificate to non-critical
