Migration from version 17.x to 18.x

You have to upgrade your PDP configuration(s), e.g. pdp.xml files, using XSLT stylesheet pdp-xsd-v7.xsl and any XSLT engine supporting XSLT 2.0, e.g. SAXON-HE 9.x or later, e.g. with this command:

$ PDP_XML_FILE="pdp.xml"
$ mv $PDP_XML_FILE{,.old}
$  java -jar Saxon-HE-10.3.jar -xsl:migration/pdp-xsd-v7.xsl -s:$PDP_XML_FILE.old -o:$PDP_XML_FILE

Migration from version 16.x to 17.x

If you are still using Java 8, you have to upgrade to Java 11 (Java 8 is no longer supported).

If you have any custom PolicyProvider extension, you need to update the implementation of the method CloseablePolicyProvider.Factory#getInstance(...) to the new PDP API (authzforce-ce-core-pdp-api: 17.0.0).

Modify the PDP configuration (XML): replace the XML namespace http://authzforce.github.io/core/xmlns/pdp/7.0 with http://authzforce.github.io/core/xmlns/pdp/7.

Make sure all your custom PolicyProviders implement the new PolicyProvider interfaces, i.e. BaseStaticPolicyProvider or, as fallback option, CloseableStaticPolicyProvider
Modify the PDP configuration (XML):
- Merge 'rootPolicyProvider' and 'refPolicyprovider' into one 'policyProvider' using the new 'StaticPolicyProvider' type if you were using 'StaticRefPolicyprovider' or 'StaticRootPolicyProvider', else your new custom PolicyProvider types if you were using custom ones.
- Add 'rootPolicyRef' element with policyId of the root policy.
- If you are migrating from v13.2.0 or lower, and using either TestAttributeProvider or MongoDBBasedPolicyProvider types in XML namespace http://authzforce.github.io/core/xmlns/test/3, you must rename them to TestAttributeProviderDescriptor and MongoDBBasedPolicyProviderDescriptor respectively.
