XShipping a Kernel Patch with Distribution

After a kernel public patch is released, the respective product team should follow the following steps to add the patches to the product distribution, if a product that is based on Carbon 4.1.0 kernel needs to ship the patch by default.

To ship a kernel patch with a product distribution:

Add the patch to the respective product distribution build. Follow the identical process that you use to add a Carbon kernel distribution (wso2carbon-core-<version>.zip) to a product distribution using the maven dependency plug-in.

Example:

<!-- Unzipping WSO2-CARBON-PATCH-4.1.0-0001-->
       <execution>
                <id>unpack-kernel-patch</id>
                 <phase>test</phase>
                  <goals>
                        <goal>unpack</goal>
                  </goals>
                  <configuration>
                            <artifactItems>
                                <artifactItem>
                                    <groupId>org.wso2.carbon</groupId>
                                    <artifactId>WSO2-CARBON-PATCH-4.1.0</artifactId>
                                    <version>0001</version>
                                    <type>zip</type>
                                    <overWrite>true</overWrite>
                                    <outputDirectory>target</outputDirectory>
                                </artifactItem>
                            </artifactItems>
                 </configuration>
        </execution>

Make sure that when the distribution gets built for a product, the libraries/jars in the patch directory (e.g., patch0xxx) gets copied to the

{CARBON_HOME}/repository/components/patches/patch0xxx directory.

Example:

  <!-- Copying WSO2-CARBON-PATCH-4.1.0-0001 files to the patches directory-->
       <fileSet>
             <directory>../p2-profile-gen/target/WSO2-CARBON-PATCH-4.1.0-0001</directory>
             <outputDirectory>wso2as-${pom.version}/repository/components/patches/</outputDirectory>
             <includes>
                  <include>**/patch0001/*.*</include>
             </includes>
        </fileSet>
