Purpose
This enhancement will provide a basic resource handler that can discover if an application as described by the SDD is installed on the system the runtime is interacting with.
Requirements
- The InstalledProductHandler must implement the IResourceHandler from the org.eclipse.cosmos.me.sdd.cr bundle.
- The IResourceHandler class is an interface that the runtime uses to load and run bundles dynamically. The IResourceHandler uses the CIM QName as defined by the component.xml data for the implemented handler as the way the ResourceHandler will discover and run the bundle.
- The InstalledProductHandler will discover products installed on both Windows and Linux platform types.
- Based on the current CIM profile, the InstalledProductHandler will recognize the following types as defined in the CIM_InstalledProduct schema:
- CIM_InstalledProduct.ProductName
- CIM_InstalledProduct.ProductVersion
- CIM_InstalledProduct.ProductVendor
Design details
- InstalledProductHandler
- The InstalledProductHandler will be introduced into the "org.eclipse.cosmos.me.sdd.cim.profile" project in eclipse CVS.
package org.eclipse.cosmos.me.sdd.advisor; public class InstalledProductHandler implements IResourceHandler { static final QName IP = new QName("http://docs.oasis-open.org/sdd/ns/cim-profile", "CIM_InstalledProduct"); static final QName IP_PNAME = new QName("http://docs.oasis-open.org/sdd/ns/cim-profile", "CIM_InstalledProduct.ProductName"); static final QName IP_PVENDOR = new QName("http://docs.oasis-open.org/sdd/ns/cim-profile", "CIM_InstalledProduct.ProductVendor"); static final QName IP_PVERSION = new QName("http://docs.oasis-open.org/sdd/ns/cim-profile", "CIM_InstalledProduct.ProductVersion"); // vendor = {0}, product = {1}, version = {2} static final String WIN_1 = "{0}\\{1}\\{2}"; // vendor\product\version static final String WIN_2 = "{1}\\{2}"; // product\version static final String WIN_3 = "{1}-{2}"; // product-version static final String WIN_4 = "{0}\\{1}{2}"; // vendor\productversion static final String WIN_5 = "{0}\\{1}-{2}"; // vendor\product-version static final String WIN_6 = "{1}{2}"; // productversion static final String UNIX_1 = "{0}/{1}/{2}"; // vendor/product/version static final String UNIX_2 = "{1}/{2}"; // product/version static final String UNIX_3 = "{1}-{2}"; // product-version static final String UNIX_4 = "{0}/{1}{2}"; // vendor/productversion static final String UNIX_5 = "{0}/{1}-{2}"; // vendor/product-version static final String UNIX_6 = "{1}{2}"; // productversion String [] unixRoots = new String [] {"/opt/", "/usr/local/"}; String [] unixPatterns = new String [] {UNIX_1, UNIX_2, UNIX_3, UNIX_4, UNIX_5, UNIX_6}; String [] winRoots = new String [] {"C:", "C:\\Program Files"}; String [] winPatterns = new String [] {WIN_1, WIN_2, WIN_3, WIN_4, WIN_5, WIN_6};
- The InstalledProductHandler uses various pattern matches to determine if a product is installed on the target host.
- The InstalledProductHandler searches well know locations as defined by work done by the Filesystem Hierarchy Standard Group. Reference to this work is provided here.
Impacts of this enhancement
- The SDD runtime will be able to resolve a deployment descriptor that defines an installed product.
