Dynamic version resolution result is incorrect when ivy metadata contains extra
attributes.

Key: IVY-1236
URL: https://issues.apache.org/jira/browse/IVY-1236
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.2.0
Reporter: Tom Liu
Ivy resolution is incorrect given the following configuration:
ivy metadata of logging#slf4j;1.6.1
<ivy-module version="2.0" xmlns:extra="http://ant.apache.org/ivy/extra";>
<info organisation="logging" module="slf4j" revision="1.6.1"
extra:tag="logging">
<description>Front end logging API.</description>
</info>
<configurations>
<conf name="runtime" description="Core runtime dependencies"/>
<conf name="jcl-bridge" extends="runtime" description="Jakarta Commons
Logging Bridge dependencies"/>
<conf name="jul-bridge" extends="runtime" description="Java Util Logging
Bridge dependencies"/>
<conf name="log4j-bridge" extends="runtime" description="Apache Log4J
Bridge dependencies"/>
<conf name="bridges" extends="jcl-bridge,jul-bridge,log4j-bridge"
description="Groups all logging bridge dependencies"/>
</configurations>
<publications>
<artifact name="slf4j-api-1.6.1" type="jar" ext="jar" conf="runtime"/>
<artifact name="jcl-over-slf4j-1.6.1" type="jar" ext="jar"
conf="jcl-bridge"/>
<artifact name="jul-to-slf4j-1.6.1" type="jar" ext="jar"
conf="jul-bridge"/>
<artifact name="log4j-over-slf4j-1.6.1" type="jar" ext="jar"
conf="log4j-bridge"/>
</publications>
</ivy-module>
ivy metadata of logging#logback;0.9.24 ivy:
<ivy-module version="2.0">
<info organisation="logging" module="logback" revision="0.9.24">
<description>Back end logging implementation that implements SLF4J
(successor to Log4J).</description>
</info>
<configurations>
<conf name="runtime" description="Core runtime dependencies"/>
</configurations>
<publications>
<artifact name="logback-core-0.9.24" type="jar" ext="jar"
conf="runtime"/>
<artifact name="logback-classic-0.9.24" type="jar" ext="jar"
conf="runtime"/>
</publications>
<dependencies>
<dependency org="logging" name="slf4j" rev="1.6.1"
conf="runtime->bridges"/>
</dependencies>
</ivy-module>
Dependencies to resolve:
<dependency org="logging" name="slf4j" rev="[1.6.1, 1.6.2]" conf="runtime"/>
<dependency org="logging" name="logback" rev="[0.9.24, 0.9.25]"
conf="build-tests->runtime" />
I would expect the following jars of slf4j are resolved:
slf4-api-1.6.1.jar, jcl-over-slf4j-1.6.1.jar, jul-to-slf4j-1.6.1.jar,
log4j-over-slf4j-1.6.1.jar
However, only slf4j-api-1.6.1.jar is resolved.
A eclipse project is attached to demonstrate the issue.
ivy metadata for slf4j 1.6.1: repo\logging\slf4j\1.6.1\ivy.xml)
ivy metadata for logback 0.9.24: repo\logging\logback\0.9.24\ivy.xml
I've debugged through and found that VisitNode does not deal with dynamic
version correctly, so that when slf4j contains extra attributes, it behaves
incorrectly:
org.apache.ivy.core.resolve.VisitNode: line 286 - 302
public boolean loadData(String conf, boolean shouldBePublic) {
boolean loaded = node.loadData(
rootModuleConf, getParentNode(), parentConf, conf, shouldBePublic,
getUsage());
if (loaded) {
useRealNode();
// if the loaded revision is different from original one
// we now register this node on the new resolved id
// this includes two cases:
// - the id refers to a dynamic revision, which has beenresolved by
loadData
// - the loaded module descriptor has extra attributes in his info tag
which are not
// used when declaring the dependency
if (data.getNode(node.getResolvedId()) == null ||
!data.getNode(node.getResolvedId()).getId().equals(node.getResolvedId()))
{
data.register(node.getResolvedId(), this);
/** If node's id is dynamic, e.g. logging#slf4j;[1.6.1, 1.6.2],
then the VisitNode will not be associated with it because only resolvedId is
considered here*/
/** The following fix associates dynamic id with VisitData as
well */
/** FIX START **/
if(!node.getResolvedId().equals(node.getId())) {
ModuleRevisionId resolvedId = node.getResolvedId();
data.register(ModuleRevisionId.newInstance(resolvedId.getOrganisation(),
resolvedId.getName(), resolvedId.getBranch(), resolvedId.getRevision()), this);
}
/** FIX END **/
}
}
return loaded;
}
I've applied this fix to handle dynamic version and then the resolution works
fine.
Thanks,
Tom
