registration of new users in xwiki from external application : appropriate rights not set
by Thomas Krämer 20 Apr '07

20 Apr '07

Hello xwiki developpers Imagine you had to powerful applications. First xwiki, then discourse engine for deliberative decision making. Lets call the latter 'dito'. Imagine how nice it would be, 1: if these two applications could use the same authentication, and if 2: signing into one aplication would sign you into the second, too. 3: registering a new account in dito would add a new user to xwiki with the appropriate rights (edit) without admin interaction (explicitly setting rights) needed @1: Done! Fortunately, as far as *authentication* is concerned, xwiki makes a geeks life easier, as it provides a XWikiAuthService interface. Which I implemented for my needs and which works fine. @2: Hm, solve 3 first @3: Stuck! Unfortunately, as far as *authorisation* is concerned, I did not yet get the point. My approach is to make an xml-rpc, that logs into the wiki (with a user that i added manually and that has admin rights) and calls the XWiki.createUser() method. In order to achieve that, i extended the ConfluenceRpcHandler and added a method createUserFromExternal Suddenly, I get an error in Xwiki, approx. line 2570(i.e. methods system.out.println("xwiki create user : !context.getUtil().match"+xwikiname);returns -4 :) try { if (!context .getUtil() .match( this.Param( "xwiki.validusername", "/^[a-zA-Z0-9_]+$/"), xwikiname)) { return -4; } } As i am calling from external, the context object (and the request, it is carrying) are not as complete as they are, when i register via the xwiki web page. My questions are: - is it a good idea to do xwiki user registration automatically and from external *that* way? do you know alternatives? - is there an implementation of the mehtod: /** * {@inheritDoc} * @see ConfluenceRpcInterface#addUser(String, java.util.Map, String) */ public void addUser(String token, Map user, String password) throws XWikiException { throw new XWikiException(XWikiException.MODULE_XWIKI_XMLRPC, XWikiException.ERROR_XWIKI_NOT_IMPLEMENTED, "Not implemented"); } ? - If you integrate xwiki into other environments or vice versa, what is the best practice to wire the two different registration and login processes of both, xwiki and some_app ? Of course, i searched the archives, but no solution for this so far... Any hints?

[Proposal] Set up the Calendar plugin in JIRA to provide visibility on release dates
by Vincent Massol 19 Apr '07

19 Apr '07

Hi, I'd like to propose setting up the JIRA Calendar plugin (http:// confluence.atlassian.com/display/JIRAEXT/JIRA+Calendar+Plugin) so that we can show the release dates of the different versions as planned. Currently these dates are only visible in the JIRA admin section and on http://www.xwiki.org/xwiki/bin/view/Main/Roadmap but it's a pain to maintain that page. In this manner we can make it visible and ensure we are all aligned on those dates. WDYT? Thanks -Vincent PS: I don't have admin access to JIRA so we might have to wait till Raffaello is back from holidays at the end of next week.

Possible memory leak ?
by Arnaud Thimel 18 Apr '07

18 Apr '07

Hi all, For a particular project, I have a plugin that reads data from an external database using some JDBC queries. For each row of my JDBC ResultSet, the plugin creates an XWiki document, the associated objects, and fill these objects. All is running fine except that I have around 50.000 objects to import :-D. Then I get a Java Heap Space exception. I re-re-re-re-re-read my source code, I don't keep any reference to the documents created. Every 200 document creation, I do the following calls : context.getWiki().flushCache(); context.getWiki().getStore().cleanUp(context); System.gc(); Anyway, the amount of memory used doesn't go down after flushing the caches. And I still get my Heap Space exception. Does anybody has an idea for me ? Who thinks that I could be a XWiki memory leak ? Thanks, -- Arnaud Thimel Société Code Lutin - http://www.codelutin.com

[Development Practice] Contributor's recognition
by Vincent Massol 17 Apr '07

17 Apr '07

Hi committers, We've already discussed this before but I've seen that we're not all following this (even though we agreed to do it on this list). I have now put it in http://www.xwiki.org/xwiki/bin/view/Community/ DevelopmentPractices#HApplyingacontributor27spatch The idea is to give proper recognition to contributors by: 1) Naming them using the specified commit log template 2) Adding them on the contributor's page on xwiki.org It would be nice if all committers could follow this and help each other follow it (I know I'm also forgetting it from time to time). Thanks -Vincent

[Anti Pattern] Do not use $obj.propertyName
by Vincent Massol 17 Apr '07

17 Apr '07

Hi, I'm proposing a new category: Anti Patterns! Here's one: Instead of writing: #set($obj = $doc.getObject("XWiki.XWikiUsers")) #if ($obj.avatar == "...") ... Write: #set($obj = $doc.getObject("XWiki.XWikiUsers")) #if ($obj.getProperty("avatar") && $obj.getProperty("avatar").getValue () == "...") ... Reason: $obj.avatar actually is equivalent to: $doc.display("avatar", $obj) And the display() method renders differently when in view mode, in inline mode, etc. For example in inline mode it generates an HTML form INPUT element... WDYT? Thanks -Vincent

[Best Practice] Test existence of properties to avoid Velocity errors in log
by Vincent Massol 17 Apr '07

17 Apr '07

Hi, Here's another one best practice I'd like to propose: Instead of writing: #set($obj = ...) #if ($obj.getSomething() == "...") Write: #if($obj && $obj.getSomething() == "...") This prevents the following error in logs: 11:54:04,777 ERROR P1-19 ... SimpleLog4JLogSystem:logVelocityMessage: 154 - Left side ($obj.getSomething()) of '==' operation has null value. If a reference, it may not be in the context. Operation not possible. [line 1, column 21] WDYT? Thanks -Vincent

[Best practice] Test for Object in Class sheets
by Vincent Massol 17 Apr '07

17 Apr '07

Hi, I'd like to propose the following best practice: to test for Object existence in class sheets. For example: #set($obj = $doc.getObject("XWiki.XWikiUsers")) #if($obj) ... #else This stylesheet must be applied on a document containing a XWiki.XWikiUsers object. #end If you're all ok I'll add it to the dev guide on http://www.xwiki.org/ xwiki/bin/view/DevGuide/BestPractices (I'll remove what's in there and send each best practice separately to this list for agreement as this is old stuff). Thanks -Vincent
