[xwiki-devs] [GSOC] help choosing a js lybrary/wrapper
by Miguel Bento 07 Jul '08

07 Jul '08

First of all, hi again! I'm developing the collaborative business drawing framework to integrate on XWiki and currently need some feedback. In order to provide the abillity of drawing SVG/VML/Canvas objects in the browser, this framework has many options that i shall explain: * A) Tatami, the GWT wrapper of the Dojo Toolkit library ( http://code.google.com/p/tatami/)* This is by far the most used option, and the reasons are somewhat obvious. - It wraps up the dojo toolkit code for GWT providing access to the GFX package's functionalities and thus giving us the possibility to draw objects in SVG/VML/Canvas. This is a very important point as it provides support for Safari with canvas objects and IE with VML objects, accomplishing thus a better product. - Provides the creation of basic and advanced drawing figures from squares to paths with drag and drop, scale, rotate and parameters specification. - It has the biggest active developer's base, having a lot of activity on their forum (http://groups.google.com/group/tatami) - It gives us efficiency and usability by being well developed. Personally, this is a key point for me as i've seen a lot of svg drawing boards slow and badly done. A demo of the tatami can be found here ( http://tatami.googlecode.com/svn/trunk/site/samples/TatamiDemo/index.html ) but don't mind the slow reaction of the site as it's using aloot of dojo objects(Fisheye, etc) and it's runing from the svn. After some coding with it, i realized it can indeed be very fast. IMHO, this looks like the winner.. we should use this wrapper for the job and if necessary develop some new items on it to provide us the required functionalities, which will also be needed in any other option. *B) JSGraphic's library ( http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm) *As it's the case with Dojo Toolkit, this library can be used in GWT by including a wrapper on the project. The downsides of this alternative are obvious as, for example, it doesn't support's drag and drop or any interaction with the objects and is a one man project. It's allways good to have options heh! *C) Develop an API fit to the job* As this option might bring some (? small) benefits in efficiency and additional funcionalities, on the other hand, it's slowed by the time required to develop the API knowing that there are some fully functional good options out there. Talking about functionalities, Tatami provides every svg object and property that i remind me of and it's efficiency and usability are high, so there shouldn't be much more to do in this area. (besides implementating screw transformations, which aren't included in the latest realease of Tatami :) In the next days i'll be building a propotype of a drawing API so please give me your opinions. My vote : +1 Tatami Best Regards, Miguel Bento.

Hi guys, I'm just downloading the 1.5M2 release to test your new administration GUI. The speed is currently 30KB/s.... I've a 100Mbit/s dedicated server located in Germany (Hoster: Hetzner). I can spend, let's say 100GB/month at full speed, would that help? Cheers, Squirrel PS: Will you sometime publish some statistics on this topic?

[xwiki-devs] [VOTE] Remove branch 1.3 builds from Continuum + Remove 1.3 branch
by Vincent Massol 04 Jul '08

04 Jul '08

Hi, I'd like to propose removing core 1.3 from Continuum. It's taking resources and the build even fails. Then I'd also like to propose removing branch 1.3 for Core/Web/XE since: * We're no longer supporting it here. * Apparently according to Ludovic it has some problems. If someone needs to release a new 1.3.3 one day he can always take the 1.3.3 tag and branch it. Here's my +1 Thanks -Vincent

[xwiki-devs] Renaming translated pages
by Vincent Massol 03 Jul '08

03 Jul '08

Hi, In order to fix issue http://jira.xwiki.org/jira/browse/XWIKI-1325 (Renaming a web page only updates backlinks in one language version) we need to store the language in the XWikiLink object/table. One solution then it modify XWikiHibernateStore from List loadBacklinks() which just return doc names to List<XWikiLink> loadBacklinks(). I have it almost done here but I wanted to ask you what you think. Another solution (but might be too complex for now) would be to include the language in doc full name by inventing a new syntax. For example: "wiki:Space.doc:language" In this case there's no change required to XWikiLink object/DB, nor for the loadBacklinks() method. The change is either in the code that calls getBackLinks() or in XWiki.getDocument(documentName) so that documentName supports language. WDYT? Thanks -Vincent

[xwiki-devs] Single Sign-On project
by Markus Lanthaler 02 Jul '08

02 Jul '08

Hi! I just created the page http://dev.xwiki.org/xwiki/bin/view/Design/SingleSignOn where I'll document everything regarding my Single Sign-On project. Since I didn't get any feedback the last time I asked this question I'll ask it again: Another question. Just looking at OpenID now. What are the plans for it? Should it be enabled by default? Should it be possible to turn it off? I would like to see OpenID support out of the box. I don't know if it makes sense to turn it off.. What happens with existing OpenID users if someone turns it off? Should we really start with the integration of a big framework like OpenSSO? Wouldn't it be better to implement OpenID support for example with a dedicated OpenID library? We should also consider the fact that ESOE for example simple uses the OpenID4Java library and OpenSSO doesn't support OpenID (authentication) at all. I think it's much easier for the user if everything is bundled with XWiki so that he doesn't need to install any other component or complex service like ESOE or OpenSSO. If it's OK for you I would start creating the architecture and describe detailed how I would like to implement OpenID support with a OpenID library the next days. Then ask for some feedback on that and finally begin to implement this. My last exam is next Monday (July, 7th) so afterwards I'm finally free to work exclusively for XWiki :-) Cheers, Markus

[xwiki-devs] [GSOC] Drawing API demo
by Miguel Bento 01 Jul '08

01 Jul '08

Hi devs, Finally, i've had the time to put up a small demo of the drawing API using Tatami(http://tatami.googlecode.com), i would like to commit it to the sandbox, but in order to do that i need write permitions for the user mjbento. Now, regarding the demo, i've only implemented the basic objects and object operations. Right now it's more of a case show of the Tatami performance than the real deal, because, in order to do that it would have to be ported into a API with all the functionalities implemented. User tip: After you finish the drawing of an object, the Select tool is automatically selected. In order to move the objects, simply click them in Select mode. So, finally, please check it out if you have some time, I would really apreciate some feedback on this. Best regards, Miguel Bento.

[xwiki-devs] How can I dynamically create a panel?
by Glenn Everitt 30 Jun '08

30 Jun '08

I was trying to figure out how to dynamically create a panel so I was looking at create.vm shown here: #if($tocreate=="panel") #set($docname=$title.replaceAll("/", "%2F")) #if(!$template || $template == "") #set($template="Panels.PanelTemplate") #end #set($newdoc=$xwiki.getDocument($docname)) #if($newdoc.isNew()) #set($pcontent = "#") #set($pcontent = $pcontent.concat("panelheader('${title}')${xwiki.getNl()}${xwiki.getNl()}#")) #set($pcontent = $pcontent.concat("panelfooter()")) #set($pcontent = $util.encodeURL($pcontent)) $response.sendRedirect($newdoc.getURL("inline", "template=${template}&Panels.PanelClass_0_name=${title}&Panels.PanelClass_0_content=$pcontent")) #else $response.sendRedirect($newdoc.getURL("view", "xpage=docalreadyexists")) #end #end . . and I quickly got lost. It looks like you first create a document from in panels space something like XWikiDocument doc = context.getWiki().getDocument("XWiki.MyPanell", context); Then it looks like $pcontent concatenates some calls to velocity macros together. Then it looks like it is url encoded so it can be passed as http response. Then I am completely lost with the sendRedirect statement. Does it redirect to process the templates and then return the response? Is there a better example for me to look at or perhaps someone generous enough to provide me with even more help? You guys have been very generous with help and I would like to Thank you!

[xwiki-devs] XML/RPC addAttachment not workink
by bd＠bc-bd.org 30 Jun '08

30 Jun '08

Hi list, I am trying to use the addAttachment call to add an attachment to a page via xmlrpc. So far I have used groovy and python (code further down), both give me the same error message: xmlrpclib.Fault: <Fault 0: 'No method matching arguments: java.lang.String, java.lang.String, java.util.HashMap, [B'> After digging into the src I found addAttachment in: XWikiXmlRpcClient.java (part of -core) /** * Add a new attachment. * * @param contentId Ignored. (It is here because the Confluence API signature declares it) * @param attachment The Attachment object describing the attachment. * @param attachmentData The actual attachment data. * @return An Attachment object describing the newly added attachment. * @throws XmlRpcException * @category ConfluenceAPI */ public Attachment addAttachment(Integer contentId, Attachment attachment, byte[] attachmentData) throws XmlRpcException { Object object = invokeRpc("addAttachment", token, contentId, attachment.toMap(), attachmentData); return (Attachment) new Attachment((Map<String, Object>) object); } As you can see contentId is defined as Integer not String. When using an integer in the rpc call I get this error message: xmlrpclib.Fault: <Fault 0: 'Failed to invoke method addAttachment in class com.xpn.xwiki.xmlrpc.XWikiXmlRpcHandler: An XWiki id must be in the form Space.Page[?param=value&param=value&...]'> When looking at the server log I can see: Caused by: java.lang.IllegalArgumentException: An XWiki id must be in the form Space.Page[?param=value&param=value&...] at org.xwiki.xmlrpc.model.XWikiExtendedId.<init>(XWikiExtendedId.java:37) at com.xpn.xwiki.xmlrpc.XWikiXmlRpcHandler.addAttachment(XWikiXmlRpcHandler.java:929) ... And when looking at that method: public XWikiExtendedId(String string) { if (string.indexOf(".") == -1) { throw new IllegalArgumentException( "An XWiki id must be in the form Space.Page[?param=value&param=value&...]"); } So question is, how do I actually add an attachment to a page?
