XWiki 9.8 released

Enygma · September 27, 2017, 4:24pm

The XWiki development team is proud to announce the availability of XWiki 9.8.

This release introduces a new feature for the Notifications: Watched Entities. It is an experimental feature that will soon replace the Watchlist Application. To try it out and get familiar with it, you need to enable it, since it is currently disabled by default.

For users, we now have more usable notification filter settings, a nice helper when you edit a “Database List” field and a feature that was missing from the CKEditor integration, which is office import.

For developers, it is easier to propose an extension containing REST resources, or to customize the Flamingo LESS code. We have also exposed more database columns in the Query Module for users who don’t have programming rights. The notification filters AST (Abstract Syntax Tree) proposes new types of nodes to create complex filter queries. There are also new facilities to avoid using SyntaxFactory, to make Extension Manager faster, or to have more control over some skin elements (CSS IDs and layout variables).

You can download it here: http://www.xwiki.org/xwiki/bin/view/Main/Download

Make sure to review the release notes:

Thanks for your support

Hello,

Not sure is the right thread to write this post, but as it is related, I will start here.
I tried to upgrade from 9.6 to 9.8 yesterday, but I got the error messages I paste at the end of this post.
I use tomcat 8.0.3, Apache 2.2.15 and Mysqld 5.1.73. The first error I saw was related to notification preferences for a specific user. Then I got this message each time I tried to upgrade (same message here it seems : Loading... ). I finally rollbacked to version 9.6.

Thanks for your help

@YannR Thanks for posting. The following looks like a bug:

java.lang.NullPointerException
        com.xpn.xwiki.XWiki.deleteDocument(XWiki.java:4016)
        com.xpn.xwiki.XWiki.deleteDocument(XWiki.java:3981)
        org.xwiki.notifications.filters.internal.migrators.ScopeNotificationFilterClassMigrator.hibernateMigrate(ScopeNotificationFilterClassMigrator.java:133)

Could you report an issue at Log in - XWiki.org JIRA ?

Thanks

Looks like we’ll need a 9.8.1. Note that it does not seems to happen for everyone since I did not got this issue when upgrading from 9.7 to 9.8 (but it was on two instances when nobody use the new annotations yet).

@gdelhumeau: ping for you

Looking at it

gdelhumeau · October 3, 2017, 9:36am

@YannR: could you please retry your migration with the this file?

All you have to do is to put it under the xwiki/WEB-INF/lib folder where your XWiki instance is installed, and remove the file named xwiki-platform-store-filesystem-oldcore-9.8.jar in the same place.

Please keep me updated!

Thanks,

Guillaume

YannR · October 3, 2017, 10:22am

@gdelhumeau thanks for your answer. I am going to test it as soon as possible. Just one question though, shall I rename the new file to xwiki-platform-store-filesystem-oldcore-9.8.jar or can I just let its name xwiki-platform-store-filesystem-oldcore-9.8-SNAPSHOT-XWIKI-14749-PATCHED.jar as it is?

Thanks,

Yann

gdelhumeau · October 3, 2017, 11:03am

You can let it as it is, as soon as you remove the old one.

vmassol · October 3, 2017, 11:07am

The important part is to remove the old JAR file. The name doesn’t matter.

YannR · October 3, 2017, 12:08pm

Thanks for your answers. I try to test the upgrade today and will let you know the result.

vmassol · October 3, 2017, 12:11pm

Thanks @YannR The faster you can tell us if it’s ok the faster we can release XWiki 9.8.1 with the fix!

YannR · October 3, 2017, 3:02pm

I was able to upgrade to 9.8 successfuly this time. Thanks a lot for your help.

Yann

gdelhumeau · October 3, 2017, 3:20pm

Thanks you, you helped us a lot Now we are almost ready to release XWiki 9.8.1

YannR · October 3, 2017, 3:21pm
