New and Noteworthy (since XWiki 5.4 Milestone 1)

Full list of issues fixed and Dashboard for XWiki 5.4.

Solr Search Improvements

The search facets now support multiple selection. Moreover, selecting a facet value doesn't hide the rest of the values of that facet. You can still see the number of results matching that value. We also decided to display a facet even when it has only one value, so that the user understands that all the results have that value for the specified facet. The facet selection is now preserved when you perform a new search. You can reset the current facets from the header of the facet pane if you want.

Advanced Search Options Removed

We decided to remove the Advanced Search Options (i.e. the search filters) because they weren't visible enough (you had to notice the arrow at the end of the search input) and, most importantly, because most of these options were duplicated by search facets, creating confusion. We integrated into the facet column the filters that were not already present there. The query boost option is no longer available but you can achieve the same thing from the query input and we'll add later a query boost configuration in the search administration section.

Following this change, we aligned the search input to the left. The reason it was centered before is because we didn't want the advanced search pane to hide the start of the first search results.

The Result Type facet has the document type selected by default. This is consistent with the old Result Type filter from the Advanced Search Options which was set to include by default only documents in the search results.

Improved File Type Facet

The File Type facet filters results based on the attachment file type. E.g. "documents that have attached images", "text attachments". File types are grouped by category. You can select both an entire category and a specific file type. Categories can be expanded and collapsed.

Improved File Size Facet

The File Size facet lets you filter the results based on the size (in bytes) of the attachments. You can new choose between 4 ranges:

  • tiny (less than 10KB)
  • small (between 10KB and 500KB)
  • medium (between 500KB and 5MB)
  • large (more than 5MB)

Debug Mode

You can enable search debug mode by adding &debug=true to the search URL query string. See the Solr Search Application for more details.

Distribution Wizard improvements

No Upgrade Mode anymore

The upgrade mode has been removed, instead both modes are kind of enabled: it's always proposed to upgrade subwikis from main wiki and the Distribution Wizard is also always enabled on sub-wikis and displayed only if there is something to do.

New report step

A new last step has been introduce to display all the changes made to the wiki and give a chance to do some rollbacks.

Activity Stream improvements

  • The name of the wiki where the event has happened is displayed now, if the event concerns an other wiki than the current one.
  • On the main wiki, Activity Stream now display events from every wikis where the current user has view right.

Miscellaneous

  • Images that are copy-pasted as HTML in the WYSIWYG editor now work fine, thanks to the added support of the Data URI scheme in XWiki Syntax 2.1. The wiki syntax is:
    image:data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAABHNCSVQICAgIfAhkiAAAAO9JREFUOE+lUrsNwjAUdCyWIBXjIEokVoCejgkyQ2gYAIkSsQUrUIUxwrund5bjX4OlyPG9u3v22Z2rjM1uWEtpkq//PC/fCs35UoHi/WGL8mTrErVsAJGJHU2KagGzHUi3I8iP+0s1nInXjBSPSfI/n2/vGTNFJZOVCRkYltdGl1FMRqmHYL0FFM6MjnFXaxCwNJMOZAbW6JyVkI1cbwcD3T5MGBjZLQxi8Lw9kp5iFFikUYwZr2dNQzQT7EavsDFOwl2ErNuIh5kgaX1E0bEyMTiZAcA0WAa26GSL7CUaHjJJz1wyqWLpe6gS/yn8AD9tcjFN7/ajAAAAAElFTkSuQmCC
  • The user and group pickers now take into account the User Scope specified when you create a new wiki. If the current wiki supports only global users then the user picker will suggest global users. If the current wiki supports both local and global users then the user picker has a toggle that lets you choose whether to get local or global suggestions. The group picker behaves slightly different because you can have local groups even when only global users are allowed (to be able to setup various rights for the global users). Thus the group picker shows the scope toggle when you are in a subwiki that accepts global users, otherwise it suggests only local groups (from the current wiki, which can be the main wiki).
  • Increased the size of the security cache to improve performances from 500 entries to 10000 entries. This setting could still be overwritten in the infinispan configuration of the cache named platform.security.authorization.cache. This new setting should be sufficient for most usages while the previous default were only valid for small single wiki.
  • Improvement in the wiki descriptor pages. It is now consistent with our vertical forms standard.

  • When the user creates a new wiki, without a template, a message is displayed to explain him the Distribution Wizard will be started to initialize the new created wiki.

  • In the Activity Stream, the name of the wiki where the event has happened is displayed now, if the event concerns an other wiki than the current one.

For Developers

New APIs to manipulate XAR files

A new "xar" ScriptService has been introduced with APIs to manipulate XAR files. It does not yet contains a lot of methods and new will be added as needed. See XAR Module extension for more details.

Deprecated and Retired projects

Upgrades

The following dependencies have been upgraded:

  • <list libraries that have been upgraded>

Miscellaneous

  • We added a new parameter to the Live Table Velocity macro named 'selectedTags' which controls the list of tags that are selected initially in the tag cloud. You can still select different tags after the live table loads. With this new parameter you can have a permanent link to a live table that has the rows filtered initially by some tags:
    ## /xwiki/bin/view/Demo/WebHome?tag=news&tag=science
    #set ($options = {
      'className': 'Demo.DemoClass',
      ...
      'tagCloud': true,
      'selectedTags': $request.getParameterValues('tag'),
      ...
    })
  • The module xwiki-platform-wiki-rest replaces the old module xwiki-platform-wiki-manager-rest in order to move xwiki-platform-wiki-manager in contrib, but the API is unchanged.
  • Verbosity of the job is now configurable right from the org.xwiki.job.Request object
  • Log generator now generates BeginEvent/EndEvent variants based on marker informations
  • The following java.lang.Class methods are now allowed in Velocity by default: name, isArray, isAssignableFrom, isEnum, isInstance, isInterface, isLocalClass, isMemberClass, isPrimitive, isSynthetic
  • Default job status does not provide log tree anymore. Was making the API too complex. It can be created from the log queue very easily in Java and a helper method has been added in logging ScriptService to create one: $services.logging.toLogTree($logs)
  • Various APIs have been added to help translate log. See Logging Module for more details
  • It's now possible to add new Images Types when rendering in XHTML
  • Introduced org.xwiki.observation.AbstractEventListener
  • New model API and script service API to create a tree from a list of entity references. See Model Module for more details
  • New option in the XAR plugin's format mojo to add missing license headers

Backward Compatibility and Migration Notes

General Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or 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 5.4RC1

New Velocity uberspector

If you modified velocity.properties = runtime.introspector.uberspect.chainClasses = ... property in xwiki.propertes file you should make sure to replace org.apache.velocity.util.introspection.SecureUberspector with org.xwiki.velocity.introspection.SecureUberspector.
