Bug#552018: Upgrading to grave

[brian m. carlson]

severity 552018 grave
kthxbye

I'm upgrading this bug report to grave, because I've done more tests
and it seems that this bug causes the resolver to produce bizarre,
inconsistent results and makes it unsuitable for a stable release.

For example, no matter what order I put the delegateURI and
delegateSystem elements in, at least one of them does not work:

<?xml version="1.0" encoding="UTF-8" ?>
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public">
	<uri name="http://www.w3.org/2001/xml.xsd"
		uri="file:///home/bmc/share/xml/schemata/xml/xml.xsd" />
	<rewriteURI uriStartString="http://docbook.sourceforge.net/release/images/"
		rewritePrefix="http://docbook.sourceforge.net/release/xsl/current/images/" />
	<delegateSystem systemIdStartString="http://docbook.sourceforge.net/release/xsl-ns/" catalog="file:///home/bmc/share/xml/stylesheets/docbook-xsl-ns/catalog.xml"/>
	<delegateURI uriStartString="http://docbook.sourceforge.net/release/xsl-ns/"
		catalog="file:///home/bmc/share/xml/stylesheets/docbook-xsl-ns/catalog.xml"/>

	<nextCatalog catalog="xhtml1.xml" />
	<nextCatalog catalog="file:///etc/xml/catalog" />
</catalog>

With System before URI:

lakeview ok % java -cp /usr/share/java/xml-commons-resolver-1.1.jar:/etc/xml/resolver org.apache.xml.resolver.apps.resolver -c ~/.crustytoothpaste/groups/metadata/xml-catalogs/catalog.xml -s http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl system
Resolve SYSTEM (systemid):
  system id: http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl
Result: file:/home/bmc/share/xml/stylesheets/docbook-xsl-ns/xhtml/docbook.xsl
lakeview ok % java -cp /usr/share/java/xml-commons-resolver-1.1.jar:/etc/xml/resolver org.apache.xml.resolver.apps.resolver -c ~/.crustytoothpaste/groups/metadata/xml-catalogs/catalog.xml -u http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl uri
Resolve URI (uri):
        uri: http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl
Result: file:/usr/share/xml/docbook/stylesheet/docbook-xsl-ns/xhtml/docbook.xsl

With URI before System:

lakeview ok % java -cp /usr/share/java/xml-commons-resolver-1.1.jar:/etc/xml/resolver org.apache.xml.resolver.apps.resolver -c ~/.crustytoothpaste/groups/metadata/xml-catalogs/catalog.xml -s http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl system
Resolve SYSTEM (systemid):
  system id: http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl
Result: null
lakeview ok % java -cp /usr/share/java/xml-commons-resolver-1.1.jar:/etc/xml/resolver org.apache.xml.resolver.apps.resolver -c ~/.crustytoothpaste/groups/metadata/xml-catalogs/catalog.xml -u http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl uri
Resolve URI (uri):
        uri: http://docbook.sourceforge.net/release/xsl-ns/current/xhtml/docbook.xsl

Three out of four of these are wrong.  A null lookup is not correct, and
using the version in /usr/share/xml is also incorrect[0], according to
this catalog.

[0] Having a private version is necessary until #562227 is fixed.
