https://integration.mediawiki.org/ci/view/All/job/MediaWiki-postgres-phpunit/depgraph-view/graph.map

is returning a URL containing localhost.

<map id="_anonymous_0" name="_anonymous_0">
<area shape="rect" href="http://localhost:8080/ci/view/All/job/MediaWiki-postgres-phpunit/" title="MediaWiki&#45;postgres&#45;phpunit" alt="" coords="27,27,307,75"/>
</map>

I think that this is likely cause by a misconfiguration at

https://integration.mediawiki.org/ci/configure

Look for "Jenkins URL" and set it to https://integration.mediawiki.org/ci you may need to restart Jenkins to make that take effect.

Thanks. I have posted your suggestion to https://bugzilla.wikimedia.org/show_bug.cgi?id=35982; I will close this bug here once WMF OPS has confirmed it (or follow up here if there is additional information).

Per https://bugzilla.wikimedia.org/show_bug.cgi?id=35982#c1, "Jenkins URL" is set to "https://integration.mediawiki.org/ci/", so the bug seems to be in Jenkins.

I don't know if it make any sense, but in our Enterprise instance it's works fine. It shows on footer "Jenkins ver. 1.424.6.1" so I guess that it is a kind of LTS, then it's equivalent to an "old" and free version.

BTW, there are no occurrences to hostname or URL in config.xml or any file in JENKINS_HOME.

In these instance we installed version 0.2 of this plugin.

Still there with Jenkins 1.472 and Dependency Graph 0.2.

Source code is on github at https://github.com/jenkinsci/depgraph-view-plugin
The culprit is
src/main/java/hudson/plugins/depgraph_view/DotStringGenerator.java which does
the following:

private String projectToNodeString(AbstractProject<?, ?> proj) {
return escapeString(proj.getFullDisplayName()) +
" [href=" +
getEscapedProjectUrl(proj) + "]";
}

private String getEscapedProjectUrl(AbstractProject<?, ?> proj) {
return escapeString(Hudson.getInstance().getRootUrlFromRequest() +
proj.getUrl());
}

getRootUrlFromRequest is most probably getting the URL based on whatever HTTP
GET Jenkins received. In our setup, there is a proxy in front of Jenkins and
hence any requests are made to 127.0.0.1:8080.

The plugin need to instead use whatever "Jenkins URL" is configured.

Our Apache conf makes https://integration.mediawiki.org/ci to be proxied to http://localhost:8080/ci

ProxyPass /ci http://localhost:8080/ci
ProxyPassReverse /ci http://localhost:8080/ci
ProxyRequests Off

<Proxy http://localhost:8080/ci*>
Order deny,allow
Allow from all
</Proxy>

.dot file on Wikimedia Jenkins installation.

Generated with Jenkins 1.472 and depgraph-view 0.2.

Should be solved in version 0.5. Please confirm.

That indeed fixed the issue. Thanks!
