Release Notes for XWiki 7.1 Release Candidate 1

Last modified by Thomas Mortagne on 2017/03/24

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

This is mostly an improvements release on new performance report design, Solr search UI and Watchlist notifications. It also introduces the experimental support for flavors in the Distribution Wizard and a new Extension History section in the administration.

New and Noteworthy (since XWiki 7.1M2)

Full list of issues fixed and Dashboard for 7.1.

New performance report improvements

The debug performance tree has been made a bit more dynamic to be able to open/close nodes.

Flavor

This feature is experimental and you should try it only for test purpose.

If no default distribution is configured, Distribution Wizard will now let you select the flavor to install.

WatchList

The realtime watchlist messages are now handled separately from the schedules (hourly, daily, weekly) notifications. We have a separate template for them and, because of this, can now display them in a more user-friendly way and they can be threaded/grouped by your email client by the document they occurred in. For more information and screenshots, please see the documentation.

New Solr search UI options

It's now possible to disable highlighting and faceting which are very slow tasks. Can be controlled directly from the search UI or from the Main.SolrSearchConfig document.

See Solr Search Application.

Extension History

The Extension Manager Application has a new section that shows the history of the extension-related actions (e.g. install, uninstall, repair, etc.) offering support for selective export, import and replay of history records. This basically means that an administrator can:

  • keep track of the extensions that are installed/uninstalled on his wiki (see who performed the action and when, in reverse chronological order, most recent first)
  • perform a couple of actions (e.g. install/upgrade a group of extensions) on a single wiki and then replay those actions on multiple wikis

Miscellaneous

  • The default document cache size has been increased from 100 to 500 elements
  • Minor visual consistency improvement of the tag cloud header of the LiveTable

For Developers

Script oriented advanced extension search API

A new script oriented API has been added to use advanced extension search possibilities introduced in 7.0. See Extension Script Module.

Record and Replay Extension Actions

The Extension Module has a new script service to access the extension history and to replay recorded history actions. The extension history records the extension related jobs (e.g. install, uninstall, etc.) along with the decisions taken by the user during the job execution (e.g. merge conflicts, delete unused pages). This means for instance that you can replay an upgrade without the need to handle again the merge conflicts.

The recording is performed by listening to the job events fired during the execution of an extension action, including the new QuestionAskedEvent and QuestionAnsweredEvent introduced in this release.

Upgrades

The following dependencies have been upgraded:

Miscellaneous

  • Extension upgrade plan job now support checking specific list of installed extensions (instead of the top level installed extensions)
  • You can now disable the automatic start of Distribution Wizard with two new options.
  • It's possible to disable minification from xwiki.properties configuration file. Set debug.minify to false.

Translations

The following translations have been updated: 

  • French

Known issues

Backward Compatibility and Migration 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.

Mail API changes

The young mail API has been refactored to provide better and more detailed error reporting. 

The MailState enumeration has been extended to report more detailed mail state (prepare_success, prepare_error, send_success, send_error and send_fatal_error). The MailListener interface has been extended to provide more detailed event. Now each mail batch should use new independent listener. The listener receive the batch identifier of its own batch when the mail preparation starts (#onPrepareBegin()), and have to keep it for all subsequent events. Independent success and error events for both the prepare and send phases are provided for each message (#onPrepareMessageSuccess(), #onPrepareMessageError(), #onSendMessageSuccess(), #onSendMessagError()). Moreover, premature interruption of the prepare phase is caught and reported (#onPrepareFatalError). Inability of the send phase to retrieve a message for sending is also explicitly reported (#onSendMessageFatalError()).

There is now more than one message state representing an error, therefore, the MailStatusResult interface has been extended with a #getAllError() method to retrieve all message status in error. Moreover, the #getTotalMailCount()# may represent a partial total in case of failure of the prepare phase. In that case, it represents the number of mails sent to the send phase. As a consequence, #isProcessed()# and #waitTillProcess()# now considerer the batch to be processed when all successfully prepared mail has been sent, or failed to be prepared or sent.

The mail API is now tracking individual message based on the standard Message-ID headers, which made it fully compliant with RFC-822 WRT the mail identification. Caller that want to specify custom Message-ID may do so by extending MimeMessage to preserve the Message-ID of the message. Caller is also responsible to ensure that different messages are identified by unique message identifier.

Sending multiple messages with the same Message-ID is no more supported since it does not respect the RFC-822 standard. 

Reusing the same Message-ID for retrying a failed message is allowed and will be tracked by the same status if the batch identifier is also reused.
