A note on usage

Magnolia CMS providing you with a Groovy app where you can create and edit your custom Groovy scripts for some development and administration purposes. For below scripts, just copy and paste them into the console, run it for your interest.

Access Content

Magnolia 4.5 & 5

session = MgnlContext.getJCRSession("website");
node = session.getNode("/demo-project")

Magnolia 4.4

hm = MgnlContext.getHierarchyManager("website")
node = hm.getContent("/demo-project")

Useful imports & initialization

import info.magnolia.cms.core.*;
import info.magnolia.cms.util.*;
import info.magnolia.context.*;

ctx = MgnlContext.getSystemContext();
MgnlContext.setInstance(ctx);
hm = ctx.getHierarchyManager("config");

Using the Visitor

visitor = {node ->
  println(node.handle)
}

ContentUtil.visit(root, visitor as ContentUtil.Visitor, new NodeTypeFilter(ItemType.CONTENT))

Visit hierarchy

root = hm.root;
ContentUtil.visit(root, new ContentUtil.Visitor(){
   visit(Content node) {
     if(node.getIndex()>1){
       print(node);
     }
   }
});

Dump a node

print(info.magnolia.cms.util.DumperUtil.dump(node));

Get Activation Status

Magnolia 5

java.lang.String querySql2 = "select * from [nt:base]";
java.lang.String queryWorkspace = "website";
javax.jcr.NodeIterator nodeList = info.magnolia.cms.util.QueryUtil.search(queryWorkspace, querySql2, javax.jcr.query.Query.JCR_SQL2, "mgnl:page");
 
println "Iterating through nodes...";
while(nodeList.hasNext()) {
  javax.jcr.Node currNode = nodeList.nextNode();
  java.lang.Integer status = info.magnolia.jcr.util.NodeTypes.Activatable.getActivationStatus(currNode);

  if (status == NodeTypes.Activatable.ACTIVATION_STATUS_MODIFIED){
    println "modified : ${currNode.path}";
  }
  else if (status == NodeTypes.Activatable.ACTIVATION_STATUS_ACTIVATED){
    println "activated : ${currNode.path}";
  }
  else {
    println "not-activated : ${currNode.path}";
  }
}
println "Node iterations done";

Set Activation Status (green)

  md = node.metaData
  md.setActivated()
  md.setActivatorId(MgnlContext.user.name)
  md.setLastActivationActionDate()

Find something in Bootstrap-files

files = ClasspathResourcesUtil.findResources(".*/mgnl-bootstrap/.*")
files.each(){name ->
  text = getClass().getResourceAsStream(name).getText()
  if (text =~ "microsoft")
    println(name)
}

Export dialogs/templates/paragraphs from a module at once to the filesystem

Each template, paragraph and dialog will be export in its own file, which is much more handy than one big file for all.

import info.magnolia.module.admininterface.pages.DevelopmentUtilsPage;
 
DevelopmentUtilsPage p = new DevelopmentUtilsPage(null, null, null);
// remember to write this file to a directory where you have the necessary permissions
// i.e. /var/lib/tomcat7/webapps/magnoliaAuthor_transa/tmp/export.xml when executing from Author
p.setRootdir("/some/place/on/your/servers/filesystem/");
p.setRepository("config");
 
p.setParentpath("/modules/myModule/templates");
p.backupChildren();
p.setParentpath("/modules/myModule/paragraphs");
p.backupChildren();
p.setParentpath("/modules/myModule/dialogs");
p.backupChildren();

Export configuration to be used in diffs

import groovy.xml.*

hm = MgnlContext.getHierarchyManager("config")
root = hm.getContent("/modules/standard-templating-kit")
// remember to write this file to a directory where you have the necessary permissions
// i.e. /var/lib/tomcat7/webapps/magnoliaAuthor_transa/tmp/export.xml when executing from Author
out = new FileWriter(new File("/Users/pbracher/workspaces/magnolia-4.2/export.xml"))

buffer = new ByteArrayOutputStream()

hm.workspace.session.exportDocumentView("/modules/standard-templating-kit", buffer, false, false)

str = buffer.toString()

def root = new XmlParser(false, false).parseText(str)

root.depthFirst().each({node ->
  if(node.name()=="MetaData"){
    node.parent().remove(node)
  }

  node.attributes().remove("jcr:uuid")
  node.attributes().remove("jcr:created")
})

def traverse(builder, node) {
    builder."${node.name()}"() {
        node.attributes().each(){attribute ->
            builder."${attribute.key}"(attribute.value)
        }
        node.children().each {
            traverse(builder, it)
        }
    }
}

builder = new MarkupBuilder(out)
traverse(builder,root)

Diff two xml files

Files exported as described above

import groovy.xml.*

homeDir = new File("/Users/pbracher/workspaces/magnolia-4.2")

def update = new XmlParser(false, false).parse(new FileReader(new File(homeDir,"update.xml")))
def installation = new XmlParser(false, false).parse(new FileReader(new File(homeDir,"installation.xml")))

def path(node){
  if(node.parent()){
    return path(node.parent()) + "/" + node.name()
  }
  return node.name()
}

def diff(left, right){
  left.children().each(){child ->
      // if text value
      if(child instanceof String){
         if(child != right.text()){
             println "${path(left)}: ${child} --> ${right.text()}"
         }
      }
      // if element
      else{
          if(right[child.name()].size() == 0){
              println "${path(child)}: removed}"
          }
          else{
              diff(child, right[child.name()][0])
          }
      }
  }
  right.children().each(){child ->
      // if text value
      if(!(child instanceof String)){
          if(left[child.name()].size() == 0){
              println "${path(child)}: added}"
          }
          else{
              if(!(child.children[0] instanceof String)){
                  diff(right[child.name()][0], child)
              }
          }
      }
  }

}

diff(update, installation)

SQL query example

Deletes nodes with null value of mgnl:template MetaData property

hm = ctx.getHierarchyManager("website")

query = hm.getQueryManager().createQuery("SELECT * FROM nt:base WHERE mgnl:template = ''", "sql")
result = query.execute()
contentCollection = result.getContent(ItemType.CONTENTNODE.getSystemName())
println "found ${contentCollection.size()} nodes"

contentCollection.each { c ->
  println "deleting ${c.name}"
  c.delete()
  }
hm.save()

Delete pages with given template type & descendant of given path

Deletes nodes that match both criterias:
- template type "website-module:pages/myShopBrand"
- descendant of "/Home/Brands"

java.lang.String querySql2 = "select * from [nt:base] WHERE ISDESCENDANTNODE('/Home/Brands') AND [mgnl:template] = 'website-module:pages/myShopBrand'";
java.lang.String queryWorkspace = "website";

javax.jcr.NodeIterator nodeList = info.magnolia.cms.util.QueryUtil.search(queryWorkspace, querySql2, javax.jcr.query.Query.JCR_SQL2, "mgnl:page");

println "Removing nodes :";
while(nodeList.hasNext()) {
  javax.jcr.Node currNode = nodeList.nextNode();
  println "${currNode.path}";
  currNode.remove();
}

info.magnolia.context.MgnlContext.getJCRSession(queryWorkspace).save();
println "Nodes removal finished";

Export a node with no children

As the ability to export a node without children is not available in the UI, you might resort to this script in case of need.

hm = MgnlContext.getHierarchyManager("website")
out = new FileWriter(new File("/Users/me/mynode-export.xml"))
buffer = new ByteArrayOutputStream()

/*
 *  last two boolean params are
 *  skipBinary A <code>boolean</code> governing whether binary properties are to be serialized.
 *  noRecurse  A <code>boolean</code> governing whether the subgraph at absPath is to be recursed.
 */
hm.workspace.session.exportDocumentView("/mynode", buffer, true, true)

str = buffer.toString()

out.write(str)

out.close()

Perform a bulk operation on nodes

Say you have 30000 users under /users/admin and you need to delete them all. Notice that the save() method is called every 1000 items so to flush the JCR session periodically and avoid a possible OutOfMemory exception if we did it only once at the end of the loop.

hm = ctx.getHierarchyManager('users')
users = hm.getContent('/admin').getChildren('mgnl:user')

count = 0
users.eachWithIndex { user, i ->
  println "Deleting user $user.name..."
  user.delete()
  count++
  if(i % 1000 == 0)
    hm.save()
}
//perform a final saving because there might be some items left in the current JCR session
hm.save() 
return "Done deleting $count users."

Export nodes with certain node types to single files

import info.magnolia.jcr.predicate.NodeTypePredicate;
import info.magnolia.importexport.DataTransporter

repository = "users"
nodeType = "mgnl:user"

session = ctx.getJCRSession(repository)
collection = NodeUtil.collectAllChildren(session.getRootNode(), new NodeTypePredicate(nodeType))
collection.each { node->
  try {
    xmlFileOutput = new FileOutputStream("/your/path/" + node.name + ".xml")
    DataTransporter.executeExport(xmlFileOutput, false, false, session, node.path, repository, DataTransporter.XML)
    xmlFileOutput.close()
  } catch (Exception e) {
    println "can't export node: " + node.path
  }
}

Remove properties from some given bootstrap files and export the clean up files

Caveat: for some reason the files output by the script are missing the prolog <?xml version="1.0" encoding="UTF-8"?>

However, one can insert it back after generating the files with a sed command, e.g.

sed -i '.original' "1s/^/<?xml version="1.0" encoding="UTF-8"?> /" dam*.xml

modules = ['ui-admincentral', 'pages', 'dam', 'contacts', 'ui-mediaeditor', 'security-app', 'ui-framework',  'sample-app', 'messages-app']
propertiesToRemove = ['label', 'icon', 'confirmationMessage', 'i18nBasename', 'description']
modules.each { module ->
  println "Cleaning up module ${module}..."
  files = ClasspathResourcesUtil.findResources(".*/mgnl-bootstrap/.*config.modules.${module}.*")
  files.each{ name ->
      
      text = getClass().getResourceAsStream(name).getText()
      println "Checking bootstrap file name ${name}..."
      xml = new XmlParser(false,false).parseText(text)
      foundPropertiesToRemove = false
 
      xml.depthFirst().each{node ->
        if(node.name()=="sv:property" &amp;&amp; propertiesToRemove.contains(node.attributes()['sv:name'])){
          //println "Node named [${node.parent().attributes()['sv:name']}] has a property named [${node.attributes()['sv:name']}] which will be removed"
          foundPropertiesToRemove = true
          node.parent().remove(node)
        }
     }
     if(foundPropertiesToRemove) {
       filePath = "/Users/me/test${name.substring(name.lastIndexOf("/"))}"
       println "Found properties to remove. Creating file $filePath ..."
       file = new File(filePath)

Permissions List

This script produces a list of permission which includes:

which user has which group and role
which group has which other group
which group has which role
what acl is defined for the role

It's meant to be used on the 4.4 branch since 4.5 has a permissions tool built it.

This script lets you migration from one DB system (e.g. Derby DB) to another one (e.g. MySQL DB). Make sure that no-one is writing any data to the repository you want to migrate from to prevent inconsistencies.

Should work with any Magnolia that uses jackrabbit 1.6+.

Magnolia 4.5 & 5

import info.magnolia.repository.RepositoryConstants;
import javax.jcr.Repository;
import org.apache.jackrabbit.core.RepositoryCopier;
import org.apache.jackrabbit.core.RepositoryImpl;

import java.io.File;

// configuration to which you want to migrate
String repositoryConfig = ""; // e.g. /some/path/WEB-INF/config/repo-conf/jackrabbit-bundle-mysql-search.xml
String repositoryFolder = ""; // target folder where files that are stored on FS will be transferred

// get current repository
Repository source = ctx.getJCRSession(RepositoryConstants.WEBSITE).getRepository();
// create RepositoryConfig from given settings
RepositoryConfig targetConfig = RepositoryConfig.create(new File(repositoryConfig), new File(repositoryFolder));
// do the migration
RepositoryCopier.copy((RepositoryImpl) source, targetConfig);

Make N copies of a Node at the same level (maybe useful for testing things like deleting multiple Nodes):

// Copy "/modules/groovy/apps/groovy" 50 times, under "/modules/groovy/apps"

// get the config workspace:
session = MgnlContext.getJCRSession("config");

// get a node:
node = session.getNode("/modules/groovy/apps/groovy");

// copy the node n times:
(50..1).each {
    NodeUtil.copyInSession(node, "/modules/groovy/apps/${it}")
}

session.save();

Automatically synchronize all registered workspaces

subscriptions = NodeUtil.collectAllChildren((ctx.getJCRSession('config')).getNode('/modules/synchronization/commands/synchronization/synchronize/subscriber/subscriptions'))
 
subscriptions.each { node ->
    workspace = (NodeUtil.unwrap(node)).getProperty('repository').getString()
     
    catalog = (info.magnolia.commands.CommandsManager.getInstance()).getCatalogByName('synchronization')
 
    command = catalog.getCommand('synchronize')
    command.setRepository(workspace)
 
    command.setPath('/')
    command.setRecursive(true)
     
    command.execute(ctx)
}

Change all Templates

    import info.magnolia.jcr.predicate.NodeTypePredicate;
   
    session = ctx.getJCRSession('website')
   
    pages = NodeUtil.collectAllChildren(session.getRootNode(), new NodeTypePredicate("mgnl:page"))
   
    pages.each { page ->
        node = NodeUtil.unwrap(page)
        template = node.getProperty("mgnl:template").getValue().getString()
   
       // println template
   
        newt = template.replace("mtk:pages/basic", "fluffy-bunny-slippers")

Export DAM files to your server folder

This script helps export all your DAM files to a specific directory from your server side.

Note that you need to create a writable folder (+w) from your server side and put its absolute path like this "/Users/vietnguyen/Downloads/dam-files/" into the script below.

Export DAM files server side

javax.jcr.NodeIterator nodeList =  info.magnolia.cms.util.QueryUtil.search("dam", "select * from [mgnl:resource] as t  where name(t) = 'jcr:content'");
while(nodeList.hasNext()) {
  javax.jcr.Node currNode = nodeList.nextNode();
  println "downloading ${currNode.path}";
  try {
    javax.jcr.Binary binary = currNode.getProperty("jcr:data").getBinary()
    InputStream inputStream = binary.getStream();

    byte[] buffer = new byte[inputStream.available()];
    inputStream.read(buffer);
    String fileName = info.magnolia.jcr.util.PropertyUtil.getString(currNode, "fileName", "noname");
    String extension = info.magnolia.jcr.util.PropertyUtil.getString(currNode, "extension", ".bin");
    String downloadFileName = fileName.endsWith(extension) ? fileName : fileName + "." + extension;

    File targetFile = new File("/Users/vietnguyen/Downloads/dam-files/" + downloadFileName);
    OutputStream outStream = new FileOutputStream(targetFile);
    outStream.write(buffer);
    println("File Downloaded in " + targetFile.getAbsolutePath());
  } catch (Exception x) {
      println("Error:" + x);
  }
}

Manually run Jackrabbit Garbage Collection

The data store never deletes entries except when running data store garbage collection. Similar to Java heap garbage collection, data store garbage collection will first mark all used entries, and later remove unused items.

Data store garbage collection does not delete entries if the identifier is still in the Java heap memory. To delete as many unreferenced entries as possible, call System.gc() a few times before running the data store garbage collection. Please note System.gc() does not guarantee all objects are garbage collected.

-- Apache Jackrabbit DataStore Garbage Collection Introduction

This would useful for customers who used Magnolia CMS for such a long time. In the snipped of code below, I am using "dam" as the highest user of Jackrabbit DataStore. Other workspaces and repositories seem not to be necessary.

org.apache.jackrabbit.core.RepositoryImpl rpi = info.magnolia.context.MgnlContext.getJCRSession("dam").getRepository();
org.apache.jackrabbit.api.management.DataStoreGarbageCollector gc = rpi.createDataStoreGarbageCollector();
gc.mark();
gc.sweep();
gc.close();

Update a system property

Did you accidentally go into production with magnolia.develop set true? Using this script you can set any System property at runtime until you get a chance to restart later.

import info.magnolia.init.MagnoliaConfigurationProperties
import info.magnolia.objectfactory.Components
import java.lang.System

propertyToBeChanged = "magnolia.develop"
// propertyToBeChanged = "magnolia.resources.filesystem.observation.excludedDirectories"

value = "false"
// value = "META-INF,WEB-INF,cache,docroot,logs,repositories,tmp"

props = Components.getComponent(info.magnolia.init.MagnoliaConfigurationProperties)
str = props.getProperty(propertyToBeChanged)

println "Changing " + propertyToBeChanged + " from " + str

System.setProperty(propertyToBeChanged, value)
str = props.getProperty(propertyToBeChanged)

println "Property " + propertyToBeChanged + " changed to " + str

Changes can be verified from the Config info subapp in the About app.

Alphabetically order a group of sibling nodes

Here is an example of how to order the modules in the config workspace.

workspace = "config";
path = "modules";

session = ctx.getJCRSession(workspace);
node = session.getRootNode().getNode(path);
outOfOrder = true;
iterator = null;
previous = null;
current = null;
        

while (outOfOrder) {
    outOfOrder = false;
    iterator = node.getNodes();

    if (iterator.hasNext()) {
        previous = iterator.nextNode();

        while (iterator.hasNext()) {
            current = iterator.nextNode();

            if (current.getName().compareToIgnoreCase(previous.getName()) < 0) {
                node.orderBefore(current.getName(), previous.getName());
                outOfOrder = true; 
            }

            previous = current;
        }
    }
 }
 
session.save();
