I am testing a patch that adds extension.json registration to Content Translation:

• https://gerrit.wikimedia.org/r/#/c/188970/

I am doing the testing on MediaWiki-Vagrant with a role/module I am writing for Content Translation (WIP):

• https://gerrit.wikimedia.org/r/#/c/180027/

For some reason, the settings applied through the ::mediawiki::extension puppet manifest and the settings that come from extension.json are both being applied instead of one being overwritten by the other. For example, if I add something like this to the MediaWiki-Vagrant module I am creating for Content Translation:

::mediawiki::extension { 'ContentTranslation':
    settings => {
      'wgContentTranslationSiteTemplates["view"]'   => '//$1.local.wmftest.net:8080/wiki/$2'
      'wgContentTranslationSiteTemplates["api"]'   => '$1.wikipedia.org/w/api.php'
      'wgContentTranslationSiteTemplates["cx"]'   => '//cxserver.wmflabs.org/v1'
    }
  }

But the extension.json file has the following:

	"config": {
		"ContentTranslationSiteTemplates": {
			"view": "//$1.wikipedia.org/wiki/$2",
			"api": "//$1.wikipedia.org/w/api.php",
			"cx": "http://localhost:8080"
		},
	}

What I end up with is urls that look like this:

http://cxserver.wikimedia.org/v1,http://localhost:8080/languagepairs

So it seems that both settings are being applied and the value is being turned into an array.

I'm not sure if this is a bug or I'm just missing something on how things should be set up. Any information would be most helpful.
