[xwiki-devs] [GSoC] pubsub idea as modyfication one from list.
by Jan J. Roman 30 Mar '09

30 Mar '09

Hi all. I would like to participate GSoC and work by XWiki. I am interested in idea "XWiki Jabber, Google Talk, Skype Integration". Main aim of described idea is to use some kind of chat rooms. Those chat rooms should be used for discuss editions and log this discussions to wiki(please correct me if I am wrong). What I propose is publish-subscribe mechanism, it is part of XMPP(Jabber/GTalk) standard. It allows to create messages categorized by nodes. When message is add, modify or delete from node there is notification sent to all subscribers (like RSS or ATOM). Main advantage of this solution is that users may use their jabber accounts for subscribe discussion or publish something in it. Here is small comparison: chat logging: * To be at home in subject someone have to read all chat log. pubsub: * You may subscribe only nodes you are interested in and ignore uninteresting. chat logging: * Chat has specific convention, there is a lot of short messages, statements are not well-thought-out, there are a lot of misunderstandings and explanations of it * After logged all chat. It may be necessary to moderate discussion. We have to create special tool for this and someone have to do the work. pubsub: * When people publish some "post" they have more time to think about it. It is possible to modify posted unclear statements. Author can even delete unnecessary own posts (in both situations all subscribers will be notify). Main disadvantage of pubsub is that it will be more difficult to port this for Skype and other closed protocols. But users can always use expected built-in XWiki pubsub client. Plese give me feedback about this idea. Jan J. Roman

There's a list of my experience concerning this application: - Java (mainly databases and web portals - JTA, JPA, JDBC, JBoss, Apache Tomcat and Jetty) - 2 years of continuous work at portal www.abclinuxu.cz - project design - (re)implementation of CSS 2.1 parser concerning easy update as specification of CSS evolves http://cssbox.sourceforge.net/jstyleparser/ - team implementation of XML database on scratch with client-server SSL access with JSP frontend sample application, abstract availablee at http://www.esiee.fr/~bureaud/Unites/Pr302i/0607/i307et05.pdf - ability to connect different pieces of code and/or software flawlessly - bachelor thesis, comparison of Wikipedia portals based on Apache Coocon with XML database exist and Stripes with 'Wicket' like extension and PostgreSQL I would like have more information what I will be supposed to do. For example, it would be great if code is done with concerning JSR-286 forward compatibility. Thank in advance for response Karel Piwko

[xwiki-devs] [GSoC2009] Google Gadget and OpenSocial Integration
by Anamaria Stoica 30 Mar '09

30 Mar '09

Hi, I need some help locating the code for Google Gadgets ( http://incubator.myxwiki.org/xwiki/bin/view/Gadgets/) I don't see it in platform/xwiki-applications or platform/xwiki-plugins (in http://svn.xwiki.org/svnroot/xwiki/) Also what is it : an application, plugin, component ? (combination of them?) Is it implemented as a container that supports the original gadgets API. How about the Open Social API ? (as the project specifies, they should both be implemented) I think it would be nice to allow users to add gadgets/open social gadgets to the sidebar as well, not only on the Dashboard page. What do you think ? Thanks, Anamaria

[xwiki-devs] [VOTE] Use annotations for new code and slowly refactor old code to use them
by Vincent Massol 30 Mar '09

30 Mar '09

Hi, I've finished the annotation implementation for registering components. The rendering modules have been migrated to annotations fully so I believe it's now strong enough to be used globally in XWiki. I'd like to propose that we use annotations for all new code from now on and slowly refactor existing code to use them. Here's my +1 Thanks -Vincent

[xwiki-devs] [Proposal] Best practice for component configuration
by Vincent Massol 30 Mar '09

30 Mar '09

Hi, So far we've been using plexus configuration mechanism in components.xml to define component configuration data. I'm proposing to drop this. Reasons: 1) This is trying us to plexus and is not generic enough for all IOC frameworks 2) It doesn't easily allow overriding config values (for ex if the user wants to override a value in a wiki page or in xwiki.properties file) I thus propose 3 things: 1) to use our new xwiki configuration mechanism to store component configuration data 2) to have a META-INF/<module prefix>.properties file located in the module jar where <module prefix> is org.xwiki.rendering for example for the rendering module (we could also have a submodule if the module is split into several modules). The idea is that the file name needs to be unique across jars so that we can create uberjars later on if need be. 3) in general we shouldn't have component-specific config data and instead make the data as generic config data as much as possible and bound to the module's Configuration component instead. For 1) and 2), it's very easy to do: - the component which requires config data need to have ConfigurationManager and ConfigurationSources injected and implement the Initializable interface and then call in initialize(): this.configurationManager.initializeConfiguration(this, this.sourceCollection.getConfigurationSources(), <prefix>); - store data using a FQN in META-INF/<module prefix>.properties, for example: org.xwiki.rendering.internal.macro.RealmMacroSource.priority = 10 In this example you would call initializeConfiguration with a prefix value of RealmMacroSource.getClass().getName(). 3) is important because otherwise users will be able to override private config data and if the internal implementation changes the config data won't be valid anymore. The reason for 2) is to hide these config data from the users as much as possible since these are advanced config options that shouldn't normally be used. For example we would defined a default priority for macros but in some very exceptional cases the user would want to change the priority so that the macro executes at a different time for a given reason. Another example if the velocity components which contain lots of data. I believe these data should be moved to a VelocityConfiguration component instead. WDYT? Thanks -Vincent

[xwiki-devs] Convert object content when changing the document syntax
by Thomas Mortagne 30 Mar '09

30 Mar '09

Hi devs, I need some help to decide what is the best to convert objects when changing the syntax. The problem is that we can't just extend the content conversion javascript to the objects because the way edit mode works the wiki/WYSIWYG and objects edit modes are isolated: the page is reloaded and content lost when switching to objects are reloaded for database. So I can see some way to do some more clean that others: 1) refactor the general edit mode to load everything and switch between content/objects without reloading the page or at least without loosing content like we do for WYSIWYG/content switch 2) let the content conversion work as it is and convert and save the objects 3) convert and save everything I think 1) would be the best, I think the user should not loose content when switching objects/content anyway. But this looks like too big for 1.8.1 which need the objects converted when content is converted. 2) is wrong IMO because this mean we will have a 2.0 document with 1.0 content/2.0 objects in it until the user save the document and worst if the user does not save the content. I think we should do 3) (with a warning to the user saying that this change can be reverted in the history) waiting for 1). WDYT ? -- Thomas Mortagne

[xwiki-devs] [GSoC] Starting with XWiki development and learning - Jabber Integration
by Tharindu Madushanka 30 Mar '09

30 Mar '09

Hi, Yesterday I have successfully build XWiki from command line and load its core platform to eclipse. And I am working with Ubuntu Linux and my environment is all set up with XWiki development tools now and from today night onwards it would be great to start some sort of development. I have to study some tutorials to get familiar with the platform more. Question on Jabber integration Please help me on deciding this. Regarding my development, should I have to come up with a component that integrates to XWiki Enterprise that will provide Jabber integration with XWiki Enterprise? or should it integrate with XWiki platform directly ?. I am still learning XWiki and sometimes this could be a bad question here. I think once I get done with the tutorials it would be fine. Please give your valuable idea on this to select and work in a specific module. It would be really helpful for me to use my time much effectively with XWiki. Thank you, *H.T.M.
