[xwiki-devs] [Proposal] Strategy for migrating to the new Model
by Vincent Massol 19 Sep '12

19 Sep '12

Hi devs, Just wanted to share my vision of how we should tackle migrating to the new Model. I see the following steps: * Step 1: Define new model interfaces (status: in progress) * Step 2: Implement a "bridged" version which uses the oldcore (status: in progress). * Step 3: Start moving code to use the new API as the new API and its implementation progress. Note: we should start using the produce of step1 and step2 ASAP to tune the details (status: not started) * Step 4: At the same time, start a new implementation based on a RDBMS (probably hibernate-based, to be decided) (status: not started). I'd also like that we start other implementations not based on a RDBMS just to prove that it works with other storages. Ideally I'd like some NoSQL impl (Caleb maybe?) and I'd also like to try a Git-based implementation (using jgit) * Step 5: Deprecate all our search apis located in XWikiHibernateStore and make everyone use the new QueryManager module. This needs some tuning on the QueryManager for missing stuff but that's doable (I need to send some proposal on missing stuff). (status: in progress). The idea here is to decouple search from storage. Note that we'll need to write some translator from HQL to XWQL or the new search query language. * Step 6: As we progress in step 2, 3, 4, introduce a configuration parameter to decide which implementation to use ("bridged", etc) so that users can start playing with new implementations (status: not started) * Step 7: Rewrite a new Importer/Exporter that exports everything (all the data in the current DB) + all configuration files/data. To see what we are currently not exporting, see http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Backup#HUsingtheXWikiEx… This new exporter should probably be based on the XWiki Streams module being developed here: https://github.com/xwiki-contrib/wiki-stream (status: in progress but not active) * Step 8: When users want to migrate from one implementation ("bridged" for ex) to a new implementation they export their wiki, set the new implementation in the configuration file and reimport. (status: not started) For me Step3 can almost begin (I probably need one or 2 more weeks to be ready to have some use cases implemented and I'll send a vote to merge my work in feature-newmodel branch in master - Would be good if you guys start looking at it and give comments to be ready for this). Then we need volunteer for Step 4 for: * new RDBMS implementation. Who? * noSQL impl. Cassandra? other? Who? * git implementation. Vincent WDYT about the plan? In term of time required it's probably going to take us about a year to have a first working version for all the steps by working at a leisurely pace. Thanks -Vincent

[xwiki-devs] dyssmetric cluster... what's up?
by Paul Libbrecht 19 Sep '12

19 Sep '12

Hello devs, we are having a very very weird bug: the two nodes of our cluster are made of A and B and saved objects sync into B when written on A but fail to do sync into A when written on B. What could be the cause? thanks in advance Paul

[xwiki-devs] [Idea] XWiki Translation Application
by Vincent Massol 18 Sep '12

18 Sep '12

Hi devs, We've been talking about this for a long time already. We've even seen what Jenkins does (go to http://ci.xwiki.org and click on the bottom left link). Today I've seen an article showing a cool new plugin for JIRA to help localize JIRA: http://blogs.atlassian.com/2012/09/inproduct-translation-plugin-beta/ Since XWiki allows overriding translation in wiki pages we have almost the same features OOB as those touted on the JIRA plugin page: * "Access Management: control which groups can translate JIRA". We have that too with wiki right management * "Instant updates: translations are saved automatically and appear immediately for all users". Same for us • "Mouse-hover: items turn green to let you know they are translatable". This is the cool part we're missing. It would be awesome to be able to do this. We should brainstorm about how to be able to do that. * "Translate Page: select from your username drop-down". We don't have that either and it would be cool to write/bundle in XE a Translation app to let users write translations in their wiki and then to contribute them with one click to l10n.xwiki.org (we'd need to put l10n on SCM too at the same time). WDYT? Any idea about how to do the "mouse-over" feature? Anyone interested by this topic? Thanks -Vincent

[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 17 Sep '12

17 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
