From 3b2a73ad85da069637a73beca432950204535979 Mon Sep 17 00:00:00 2001
From: Ondrej Dubaj <odubaj@redhat.com>
Date: Wed, 22 Jul 2020 11:39:42 +0200
Subject: [PATCH] Fix for XXE vulnerability
by defaulting to disabling external access and doc types. The
legacy insecure behavior can be restored via the new connection property xmlFactoryFactory
with a value of LEGACY_INSECURE. Alternatively, a custom class name can be specified that
implements org.postgresql.xml.PGXmlFactoryFactory and takes a no argument constructor.
* refactor: Clean up whitespace in existing PgSQLXMLTest
* fix: Fix XXE vulnerability in PgSQLXML by disabling external access and doctypes
* fix: Add missing getter and setter for XML_FACTORY_FACTORY to BasicDataSource
