[xwiki-devs] [Proposal] XWiki Days every month?
by Vincent Massol 18 Sep '12

18 Sep '12

Hi devs, We've had several special days in the past: * Deprecation day ** 26 April 2012: http://markmail.org/thread/c5oytyvgw6fcimqq * Bug fixing days: ** 11 june 2008: http://xwiki.markmail.org/thread/oyfxis3umqrvutxm ** 18 June 2008: http://xwiki.markmail.org/thread/brfx6gme37vgr3m5 ** 25 Jun 2008: http://markmail.org/message/nrobo3x4ppgssklk ** July 2008: http://xwiki.markmail.org/thread/mn5veblndbtgcsm5 ** 10 Feb 2011: http://xwiki.markmail.org/thread/rierrb2wk72dkpqy and result http://www.xwiki.org/xwiki/bin/view/Blog/BugFixingDayFebruary2011 * DocHour days: ** 5 March 2008: http://xwiki.markmail.org/thread/dyypju5dn23wkwr2 I think it's a good concept and I'd like to propose that we regularly (once every month?) have an XWiki Day. Ideas for such days: * Bug fixing day: Reduce bug count * Doc day: improve xwiki.org * Deprecation day: reduce # of deprecated calls. Around 1700: http://nemo.sonarsource.org/drilldown/violations/XWIKI?&rule=squid%3ACallTo… * Violation day: reduce # of violations. 10274 right now: http://nemo.sonarsource.org/drilldown/violations/XWIKI * Javadoc Day: Add missing javadocs in our code and remove checkstyle excludes * Code Coverage Day: Add as many tests as possible (unit and functional) * Broken Links Day: fix as many broken links as possible on xwiki.org. To find them is easy: we just need to enable the IRC Link Checker botlet and wait on IRC to get them! I propose that whenever a day is over, we send a mail with the Date and Topic for the next day and it has to be about 1 month from the date of the mail. To get this started I volunteer to be responsible for sending Day emails for now, unless someone else is interested to do this. WDYT? Thanks -Vincent

[xwiki-devs] Public pages within a secured/private Xwiki app with custom authentication
by echocoder 18 Sep '12

18 Sep '12

Is it possible to have a page in the Xwiki visible and viewable to the "public" that is not under the control of the custom authentication class defined in the config? Currently, I have a JSP file that collects user credentials that are placed in the HTTP session used for login. However, when the user is authenticated and redirected to the /xwiki web application those session values are no longer there so the Xwiki just loops back to the JSP file looking for credentials. What I would like to do is have something like /xwiki/public/login where the user is prompted to enter their credentials which is then processed by the custom authentication and sends the user to /xwiki/private. By setting the xwiki.authentication.authclass to a custom authentication class... it seems like it is an all or nothing approach to where I cannot have a subset of pages open to the public. -- View this message in context: http://xwiki.475771.n2.nabble.com/Public-pages-within-a-secured-private-Xwi… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Setting a session variable in the Xwiki Context to a value defined in HTTP session
by echocoder 14 Sep '12

14 Sep '12

My instance of Xwiki is using custom authentication. I have a new requirement to add Yubikey based authentication now. I believe in order to pull it off, I need to set a session attribute in the Xwiki context with a value defined in a JSP file. I tried to set it in the current HTTP session, with the code below but it is not showing up in the Xwiki context session when the checkAuth method is called ... session.setAttribute("okc_sso_username", username); ... public XWikiUser checkAuth(XWikiContext context) throws XWikiException { .... String okc_sso_username = (String)context.getRequest().getSession().getAttribute("okc_sso_username"); .... } Any idea on how to bind the two to make a JSP session variable available in the XwikiContext? -- View this message in context: http://xwiki.475771.n2.nabble.com/Setting-a-session-variable-in-the-Xwiki-C… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Difference between 3.1 and 4.2 for object's implementation in oldcore.
by Karel Gardas 14 Sep '12

14 Sep '12

Hello, I'm trying to update our semantic extension for xwiki from 3.1 to 4.2 to be able to release this as an open-source finally. Now, it looks like something inbetween 3.1 and 4.2 changed in xwiki-platform-oldcore's com.xpn.xwiki.objects* since my current 4.2 setup complains a lot with a message like: Wrapped Exception: Error number 7006 in 7: Cannot find property class com.xpn.xwiki.objects.classes.SPARQListClass in MetaClass object The SPARQListClass is our implementation of the list class which provides dynamic list based on the supplied SPARQ query and which was of course working well on top of 3.1. I'm looking into all the classes in 4.2's com.xpn.xwiki.objects subdirectory but so far I'm not able to distill what change between 3.1 and 4.2 breaks our SPARQList. Any idea what's going wrong or where should I have a look is highly appreciated. Thanks! Karel

[xwiki-devs] [Brainstorm] Web sites where we should announce XWiki releases
by Vincent Massol 14 Sep '12

14 Sep '12

Hi everyone, I'd like to improve our tech marketing by sending XWiki release announcements to web sites that people know about/use. So this thread about brainstorming about those sites. So what sites do you think we should send release announcements to? Note that at the moment we publish on: - Wikipedia: * http://en.wikipedia.org/wiki/XWiki * http://fr.wikipedia.org/wiki/XWiki * http://en.wikipedia.org/wiki/Comparison_of_wiki_software - FreeCode: * http://freecode.com/projects/xwiki/releases/new - Wikimatrix: http://www.wikimatrix.org/edit/XWiki - OW2: - http://forge.ow2.org/projects/xwiki Also note that news published on FreeCode are republished by other news sites (I don't have the list). So let me start by proposing: - DZone: * http://www.dzone.com/links/index.html * Submission form: https://www.evernote.com/shard/s119/sh/29a1d696-d2e3-4c3f-a1a1-b296296b8e04… Please add yours here! Thanks -Vincent

[xwiki-devs] [VOTE] Also add a link on DZone when performing a Release
by Vincent Massol 14 Sep '12

14 Sep '12

Hi devs, When we release a new version we publish the announcement in several places (wikimatrix, freshmeat, wikipedia). I'd like to propose that we add DZone too. For example I've just seen that GateIn 3.4 has been announced there: http://www.dzone.com/links/gatein_34_is_released.html DZone is very well know and I think it would help spread the word even more about XWiki. So here's my +1 to add DZone to the list of sites to update when we release. Thanks -Vincent

[xwiki-devs] Xwiki 4.1.4 - Admin-Presentation page is blank
by echocoder 13 Sep '12

13 Sep '12

I have updated to XWiki Enterprise 4.1.4. However, it seems to not have captured the skins/CSS I was using. in my old Xwiki instance. When I log in and go to the Administer Xwiki page, the Presentation section is blank. Is there another way to view/set the default skin value? -- View this message in context: http://xwiki.475771.n2.nabble.com/Xwiki-4-1-4-Admin-Presentation-page-is-bl… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] [Proposal] Add cropping API to image plugin
by Jerome Velociter 13 Sep '12

13 Sep '12

Hi devs, I've already proposed a thumbnail module in the past (http://markmail.org/thread/3le7qxziog2p7bsd) but it felt short in terms of design. I reckon it's more of a URL cache module for images/thumbnails and probably doesn't make much sense in the platform. I would like still to propose one change separately, that was going together with this module : adding a cropping API to the current image plugin. This would allow to not only pass dimensions information when downloading an image, but also to pass coordinates to crop a subimage out of the original image. Practically, it's adding a "boundaries" URL parameter (in addition to the existing width, height, quality and keepAspectRatio existing parameters), that is a comma separated list of x, y, width and height used to construct the subimage. Right now the code is in https://github.com/jvelo/xwiki-platform-thumbnails/tree/master/src/main/jav…, I will make a proper pull request to discuss the patch if their is interest. Note I also have a generic UI component to perform resizing and store image boundaries for an attachment in an XObject that I can share (and even plug into the user profile for example). On the longer term, their is a discussion to have around how to wire attachment transformation from URLs. Maybe a "transformations" URL parameter that takes a list of hints of transformation components ? Then the resizing/cropping could be implemented as transformations in a new image module ? WDYT ? Finally, finishing note, I've also written a new image processor for the current image plugin API, based on https://code.google.com/p/java-image-scaling/ that yields images of much better quality compared to the current implementation based on awt/graphics2d. See for example the before/after : http://imgur.com/oU9v5 (for the before, those had a quality param of "1", i.e. maxed out). Code is there : https://github.com/jvelo/xwiki-platform-thumbnails/blob/master/src/main/jav…. One thing I didn't do yet is to extract a superclass from it and the base impl. If there is interest, we could provide this processor as an alternative. Maybe with a parameter config to pass the hint of the processor to use. WDYT ? Thanks, Jerome

[xwiki-devs] best practice to programme with XWiki objects?
by Paul Libbrecht 13 Sep '12

13 Sep '12

hello fellow developers, at Curriki, we are starting to process XWiki objects in the background using subclasses of AbstractXWikiRunnable. Currently I do the following: // setup XWikiContext xcontext = (XWikiContext) Utils.getComponent(Execution.class).getContext() .getProperty(XWikiContext.EXECUTIONCONTEXT_KEY); Context context = new Context(xcontext); XWiki xwiki = new com.xpn.xwiki.api.XWiki(context.getXWiki(), xcontext); // fetch background info Document d = xwiki.getDocument(DOCNAME_x); Object obj = d.getObject("DOCNAME_class"); // modify something // save d.save("comment"); However, I wonder if this is the best practice: - is it expensive to construct a context and xwiki supposing this setup code is run multiple times? - is it preferrable to work with the com.xpn.xwiki.* classes? - is DocReference behaving much differently than fullName if we have a single wiki? Thanks in advance. Paul
