Release Notes for XWiki 4.2 Milestone 3

Last modified by Vincent Massol on 2012/09/25

This is the release notes for XWiki Platform, XWiki Enterprise and XWiki Enterprise Manager. They share the same release notes as they are released together and have the same version.

This is the third and final milestone of the XWiki 4.2 version (Roadmap).

New and Noteworthy (since XWiki 4.2 Milestone 2)

Improved upload UI

The new HTML5 FileUploader has been integrated in a few places:

  • The standard attachment upload form
  • The Import section of the Administration

See below for more details about this feature.

New logging administration UI

It's now possible to review and modify the log level for all registered loggers.

Experimental install/upgrade wizard

Accessing a wiki page in view mode after an upgrade or when the database is empty (new install) will trigger a wizard that will allow you to install or update the default set of wiki pages and to upgrade or downgrade the extensions you may have previously installed.

The wizard currently has two steps. In the first step you can see which XWiki distribution you are running and what is its recommended default set of wiki pages (the default user interface). You should install, upgrade or downgrade the UI so that it matches the distribution version.

The step has three possible actions:

  • Skip means 'go to the next step and ask me again after a server restart'
  • Cancel means 'go to the next step and don't ask me again until I change my distribution'
  • Continue, only after the recommended UI version is installed

In the second step you can upgrade the installed extensions. We group them in two categories:

  • extensions that don't work with your current distribution but which have new versions available that are compatible with your current distribution. These extension require an upgrade.
  • extensions that should work fine with your current distribution but which have upgrades available. Upgrading these extensions is optional.

You can refresh the list of extensions by clicking on the Reload button. The Skip and Cancel buttons have the same meaning as in the previous step. The Continue button is available only after the required upgrades are performed.

At the end you'll be redirected back to the wiki page you have accessed in the first place.

New Applications Panel

There's now a new "Applications" panel by default in XWiki Enterprise. This panel displays the applications present in your wiki.

Administrators will get a couple of additional links, allowing them to install applications through the Extension Manager, or to create new applications thanks to the App Within Minutes feature.

Note for application developers: your applications can provide their own entries in this menu by declaring a UI Extension.

Chart Macro Improvements

New Content Macro

The new Content macro allows to enter content in any of the supported Syntaxes and thus allows to have content written in various syntaxes. For example, in a page in XWiki Syntax 2.0:

This is in **bold**

{{content syntax="confluence/1.0"}}
This is *bold* too!
{{/content}}

Documents Macro improvements

The {{documents}} macro now supports specifying the list of columns to display. For example:

{{documents count="5" actions="false" space="Main" parent="Main.WebHome" columns="doc.title"/}}

would display:

documents-columns.png

Search improvements

The Lucene index also stores the MIME type of the indexed attachments, allowing to customize the search to only include or exclude attachments of a certain type. The new field is named mimetype and it contains a valid MIME type string, as returned by the container in which XWiki is running. For example, add -mimetype:image/* to a query to exclude all image attachments from the results, or add mimetype:application/pdf to only search inside PDF attachments.

Remember that in case of an upgrade, you have to rebuild the entire index to have this new field for existing documents.

Miscellaneous

  • The IRC Bot Application now recognizes XAR import events and when receiving one, it doesn't send subsequent IRC notifications for modified or created documents to avoid spamming the IRC channel.
  • Display the request URL in the IRC channel when the Link Checker bot listener is active and a broken link is found, thus making it easier to reproduce and debug the broken link

For Developers

New HTML5 File Upload widget

The File Upload widget can enhance HTML input elements of type file to provide an interactive upload UI. It can submit files either automatically when the user selects local files, or after the user presses the container form's submit button.

To use this widget, it is enough to create a new instance of XWiki.FileUploader passing the target input element as the first parameter, and an optional configuration object as the second parameter.

new XWiki.FileUploader(targetInput, {
  autoUpload: true,
  progressAutohide: true
});

JSRX and SSRX

It's now possible by default to add skin extensions located in JAR files. Example usage:

$xwiki.jsrx("/lib/codemirror.js")
$xwiki.ssrx("/lib/codemirror.css")

Attachment Picker improvements

It is now possible to specify a different document for the source (and target in case of uploads) of attachments, using the new targetdocname macro parameter.

Extension Manager improvements

  • the custom Maven property <xwiki.extension.features> now accept any number of new lines and white spaces between elements
       <xwiki.extension.features>
          org.xwiki.platform:xwiki-platform-oldcore,
          com.xpn.xwiki.platform:xwiki-core
       </xwiki.extension.features>
  • new custom properties added to overwrite standard Maven properties:
    • xwiki.extension.name to overwrite <name>
    • xwiki.extension.summary to overwrite <description>
    • xwiki.extension.website to overwrite <url>

XAR format improvement

It's now possible to indicate the extension identifier right in the XAR package descriptor (package.xml). Among other things this allow standard import UI to find what it currently importing and register it automatically as installed extension if it can be found in the registered repositories during import process.

The XAR Maven plugin automatically take care of adding this information to the generated package.xml for Maven project. If for some reason you need to indicate it by hand you can use the property <extensionId> under the the <infos> element in the package.xml file.

<package>
 <infos>
   <name>XWiki Platform - Extension - UI</name>
   <description>XWiki Extension Manager, an application for managing extensions in a wiki.</description>
   <licence></licence>
   <author>XWiki.Admin</author>
   <extensionId>org.xwiki.platform:xwiki-platform-extension-ui</extensionId>
   <version>4.2-SNAPSHOT</version>
   <backupPack>true</backupPack>
 </infos>
 <files>
    [...]
 </files>
</package>

New UI Extension mechanism (experimental)

We're in the process of allowing applications to insert custom content in pre-defined places in the user interface. A first Extension Point has been defined in the new "Applications" panel, you can read more about this in the UI Extension module documentation.

Upgrades

The following dependencies have been upgraded:

  • Prototype.js 1.7.1
  • Jython 2.5.3
  • Pegdown 1.1.0 (used by the XWiki Markdown Parser)
  • Xalan 2.7.1

Miscellaneous

  • The AbstractMockingComponentTestCase testing framework class has been modified. Read the Testing page for more details on how to use it.

Translations

The following translations have been updated: 

  • French
  • Portuguese (Brazil)
  • Swedish

Tested Browsers

Known issues

Backward Compatibility and Migration Notes

General Notes

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Always make sure you compare your xwiki.cfg and xwiki.properties files with the newest version since some configuration parameters were added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

Issues specific to XWiki 4.2 Milestone 3

QueryFilter implementations must not be considered as singletons anymore

Since some QueryFilter such as the "hidden" filter are not singletons anymore (ie. now a new instance is created for each lookup), they need to be retrieved with a dynamic lookup.

If you were using injection to get filters, for example:

@Inject
@Named("hidden")
QueryFilter filter;

This MUST be replaced by the following in your code:

@Inject
@Named("hidden")
private Provider<QueryFilter> hiddenFilterProvider;

/* ... */

QueryFilter hiddenFilter = hiddenFilterProvider.get();

This code will work no matter the instantiation strategy of the implementation, Singleton or Per Lookup.

API Breakages

The following APIs were modified since version 4.1.4:

  • The logging module is new and is still considered a "young API". Added new methods to manipulate loggers levels.
    org.xwiki.logging.LoggerManager: Method 'public org.xwiki.logging.LogLevel getLoggerLevel(java.lang.String)' has been added to an interface
    org.xwiki.logging.LoggerManager: Method 'public java.util.Collection getLoggers()' has been added to an interface
    org.xwiki.logging.LoggerManager: Method 'public void setLoggerLevel(java.lang.String, org.xwiki.logging.LogLevel)' has been added to an interface
  • The Job module is new and is still considered a "young API". Added two new methods to check and remove custom properties.
    org.xwiki.job.Request: Method 'public boolean containsProperty(java.lang.String)' has been added to an interface
    org.xwiki.job.Request: Method 'public java.lang.Object removeProperty(java.lang.String)' has been added to an interface
  • New InstalledExtension#isValid() method.
    org.xwiki.extension.InstalledExtension: Method 'public boolean isValid(java.lang.String)' has been added to an interface
  • The Extension module is relatively new and is still undergoing some API tuning. New method to access environment extension. Also added new methods to execute custom checking before installing/uninstalling an extension and new methods to access local:installed extensions.
    org.xwiki.extension.repository.CoreExtensionRepository: Method 'public org.xwiki.extension.CoreExtension getEnvironmentExtension()' has been added to an interface
    org.xwiki.extension.handler.ExtensionHandler: Method 'public void checkInstall(org.xwiki.extension.Extension, java.lang.String, org.xwiki.job.Request)' has been added to an interface
    org.xwiki.extension.handler.ExtensionHandler: Method 'public void checkUninstall(org.xwiki.extension.InstalledExtension, java.lang.String, org.xwiki.job.Request)' has been added to an interface
    org.xwiki.extension.repository.InstalledExtensionRepository: Method 'public org.xwiki.extension.InstalledExtension getInstalledExtension(org.xwiki.extension.ExtensionId)' has been added to an interface
    org.xwiki.extension.repository.LocalExtensionRepository: Method 'public org.xwiki.extension.LocalExtension getLocalExtension(org.xwiki.extension.ExtensionId)' has been added to an interface
  • Fix method name typo (adding new method). This interface is not really supposed to be implemented except by internal class.
    org.xwiki.properties.PropertyDescriptor: Method 'public java.lang.reflect.Field getField()' has been added to an interface
  • The method getPreviousBlockByType() was moved to Legacy. There's no API breakage for the user.

  • These classes below have never been used. It was supposed to be the start of the removal of Struts but since it hasn't progressed so far we're removing stray code from master. Experiments should be done on feature branches.
    org.xwiki.container.servlet.XWikiServlet: Class org.xwiki.container.servlet.XWikiServlet removed
