[xwiki-devs] CTS Syntax Report on xwiki.org

by Vincent Massol

Hi devs, As you probably know from http://jira.xwiki.org/jira/browse/XRENDERING-187, I've been working on a Compatibility Test Suite (CTS) for the Rendering Syntaxes. I've now added a Test Report on xwiki.org at http://rendering.xwiki.org/xwiki/bin/view/Main/SyntaxReport It allows to have a global view of what each syntax supports. Of course this is a very first version and the idea is to improve it over time. Note 1: Right now we have only 6 tests in the CTS. Note 2: ATM the Report gets its data from the Sonar Nemo instance at http://nemo.sonarsource.org/dashboard/index/178313 However this instance only runs the xwiki build every few days. I've made modifications this morning to the CTS but the build hasn't run yet on Nemo. I need to check if I can get the same result using Jenkins Remote API. Let me know what you think. Thanks -Vincent

[xwiki-devs] [GSOC] [Status Request] Middle of Community Bonding period

by Eduard Moraru

Hello students, As you probably already know, we are almost at the middle of the community bonding period [1]. >From the previous mail [2] and XWiki's GSoC page [3], you also know that this is the time where you learn about XWiki's development processes, code and community and, to better understand the code, you must fix at least one jira issue related directly or indirectly to your project. This is in no way a radio silence period, quite the contrary. In other words, you need to: 1. Answer this mail :) 2. Create a Design page [4] regarding your project 3. Start idling on the IRC channel 4. Start chatting on the mailing list and on IRC about your project and other aspects of XWiki that you don't yet understand 5. Get your hands dirty by diving into the code and fixing at least one Jira issue (2 more weeks left) 6. Talk about your project What we want from you with this mail is to see where you stand with regard to what has been written above. We want to know what you don`t understand about XWiki, what issue you are planning to undertake, what you want to start with, etc. It helps you more to start saying incorrect things and fixing them early instead of staying quiet and making a big bad choice towards the end. And a last thing, please remember that one-to-one conversations with your mentor are not encouraged and are actually harmful to the success of your project. Talk to the community, ask for help early and life will be sweeter :) Thanks, Eduard ---------- [1] http://www.google-melange.com/gsoc/events/google/gsoc2012 [2] http://markmail.org/thread/u6jhsqwxn6uitcjo [3] http://gsoc.xwiki.org [4] http://dev.xwiki.org/xwiki/bin/view/Design/WebHome

[xwiki-devs] My xwiki login page always redirects to localhost

by Geo Du

Hi, all, I got a problem with our xwiki site setup, I have apache webserver and tomcat behind with xwiki 3.5 deployed, when I do login, logout or clicking buttons on the server machine browser with http://localhost:8082/xwiki/bin/login/XWiki/XWikiLogin, I can login, everything works fine, but if I use external public internet to access our xwiki site like: http://mydomain.com/xwiki/bin/login/XWiki/XWikiLogin, I got the login page shown up, but if I login, it redirects me to localhost/xwiki/bin/view/Main/WebHome, which points to my localhost, not my server mydomain.com machine, then from the browser address bar, if I change the localhost url to this url: http://mydomain.com/xwiki/bin/view/Main/WebHome, I can see the page correctly. Hers is my httpd.conf file setup: ProxyPass /xwiki http://localhost:8082/xwiki ProxyPassReverse /xwiki http://localhost:8082/xwiki Any clue what is going on? Thanks Dave

[xwiki-devs] [GSOC] Documenting a student's progress

by Eduard Moraru

Hi students, This year we thought about changing a bit the way we track a student's progress. As you may have seen in previous mails [1], we expect students to document their work/progress in 2 ways: 1) Design page in the Design [2] space on xwiki.org GSoC students should create a Design page where they document technical aspects of the feature they are working on: architecture, use cases, problems, various solutions with pros and cons, etc. This page should be written as an XWiki community member and not a GSoC student (there is the progress report for that), ensuring that the page will remain relevant even after the GSoC period ends. 2) 'Progress' section of the GSoC project [3] for which the student has been accepted This is the place where the students set their goals (milestones and deliverables) and where they report their advance towards completing them. More details and examples are available at [4]. Thanks, Eduard ---------- [1] http://markmail.org/message/tdjr4wjm6hwswghr [2] http://dev.xwiki.org/xwiki/bin/view/Design/ [3] http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/WebHome#HSelectedPro… [4] http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/DocumentingStudentPr…

[xwiki-devs] Some difficulties with unit testing ...

by jerem

Hello, Seems I did not understand everything about how to write unit tests ... Here's my problem : I want to test a class MA, a component, that has the following code (excerpt) : My test class MATest contains : Here I'm looking up the Execution in order to set expectations on it for the initialize to pass. Problem is that I'm still getting this at test execution : It seems that my initialize() method is called at lookup(), so how could I set-up the expectations before they're actually exercised ? : Thanks for help, Jeremie -- View this message in context: http://xwiki.475771.n2.nabble.com/Some-difficulties-with-unit-testing-tp749… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] An appeal for insight into the development of XWiki

by Martin Schönberger

Dear developers of XWiki! I am a student of Software Engineering at the Vienna University of Technology and currently writing my master thesis on project management and the development methods used in open source projects. In my research I analyzed open source development and compared it with elements found in various proprietary approaches, both agile and well-defined. But to provide balanced and up-to-date results my work relies on first- hand information and expert opinion, for which I need your help. XWiki matches my criteria regarding size, activity and available information and I would be glad to include it in my case study. I am looking for an interview partner with good insight into the project structure and a solid overview of all stages of development, ideally a member of the core team with long-term dedication to the project. The interview would take about 20 minutes on Skype (or a similar phone- based tool). If you prefer a written chat, that can be arranged as well. My daily schedule is flexible, so whatever time suits you best should work for me. The subject areas I would like to cover in the interview are XWiki's: * Development flow and release cycles * Social structures, responsibilities and decision making * Code structure and architectural considerations * Special conditions caused by the open source environment I realize your time might be scarce, but if you decide to contribute to this case study your help shall be all the more appreciated. Once finished I will gladly share my results and any new insights gained on the topic with you. Kind regards, Martin Schönberger (maschonber(a)gmail.com)

[xwiki-devs] Concurrency issue in REST server module

by Marius Dumitru Florea

Hi Fabio and devs, I found a serious concurrency issue in the REST server module while debugging the instability of the Extension Manager when extensions.xwiki.org repository is used (default case) . The Extension Manager UI searches extensions using REST and very often it gets 500 HTTP response code. See http://jira.xwiki.org/browse/XWIKI-7773 for instance. The server log from xwiki.org shows that the real cause is: May 8, 2012 5:09:14 PM org.restlet.engine.application.StatusFilter doHandle WARNING: Exception or error caught in status service java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372) at java.util.AbstractList$Itr.next(AbstractList.java:343) at org.xwiki.rest.XWikiSetupCleanupFilter.afterHandle(XWikiSetupCleanupFilter.java:73) See the full stacktrace http://pastebin.com/hnFSuwem . The problem is related to the way "releasable components" are managed. I debugged locally both XWikiSetupCleanupFilter [1] and ComponentsObjectFactory and here's what I discovered: * org.restlet.Context.getCurrent() is shared across HTTP requests * as a consequence, restlet context attributes are shared across HTTP request * RELEASABLE_COMPONENT_REFERENCES context attribute is thus also shared * while a thread iterates this list in XWikiSetupCleanupFilter another thread can add a component to the list in ComponentsObjectFactory * the list grows indefinitely because XWikiSetupCleanupFilter only releases the components; it doesn't remove them from the list * older instances are re-released * since the list keeps references to older instances these instances can't be garbage collected Could someone more knowledgeable on the REST module (especially Restlet) review my findings? Thanks, Marius [1] https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi… [2] https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…

[xwiki-devs] Tag edit in Document Information panel

by Marius Dumitru Florea

Hi devs, Until recently the Document Information panel was letting the users edit the document tags, as indicated on http://extensions.xwiki.org/xwiki/bin/view/Extension/Tag+Application . Sergiu removed this feature in https://github.com/xwiki/xwiki-platform/commit/2e4b54267b9bf4048c14fdf14b6a… . The commit message doesn't mention this and since the style sheet extension object related to tags edit was kept (and is still present in the current version) I though initially that this was a mistake. After I put it back locally I discovered the feature wasn't working well. I've made this changes http://pastebin.com/11ewzxYz to fix some of them but there is still one big issue: you can't remove all tags because https://github.com/xwiki/xwiki-platform/commit/2d2d3b2de71b6de5a078ffccec63… which fixes http://jira.xwiki.org/browse/XWIKI-2545 . Do we want to keep/maintain this feature? There is at least one users that requested it. See http://lists.xwiki.org/pipermail/users/2012-May/022729.html . Thanks, Marius

[xwiki-devs] Creating a standalone distribution of the WYSWIG

by Jerome Velociter

Hi team, Just to let you know I've started splitting the WYSIWYG module in order to create a standalone distribution of the editor, to make it easier to use outside XWiki. The new structure of the module would be : ├── xwiki-platform-wysiwyg-client │ ├── xwiki-platform-wysiwyg-client-standalone │ └── xwiki-platform-wysiwyg-client-xwiki ├── xwiki-platform-wysiwyg-plugin-api ├── xwiki-platform-wysiwyg-server └── xwiki-platform-wysiwyg-war ├── xwiki-platform-wysiwyg-war-standalone └── xwiki-platform-wysiwyg-war-xwiki Note that the standalone WAR distribution would only be built when releasing, otherwise it means we almost double the overall time of the WYSIWYG build. I'm not sure we can work around that so easily due to the way GWT works ; Marius maybe you can hint me here. You can check out the split here : https://github.com/jvelo/xwiki-platform/compare/XWIKI-7785 Jerome

[xwiki-devs] [VOTE] Allow to filter query result lists with QueryFilter (new API)

by Jean-Vincent Drean

Hi, I'd like to introduce a new API in QueryFilter: ====================8<==================== /** * Filter a list of query results. The result list can be returned without modification. * * @param results the original result list. * @param <T> expected type of elements in the result list. * @return a filtered result list. */ <T> List<T> filterResults(List<T> results); ====================8<==================== In addition to QueryFilter#filterStatement(), this method would be called from the QueryExecutor and it would allow the filter to mofidy the result list of a query. We talked about this one before with Thomas and Vincent but the use case we were thinking about wasn't achievable (permission checking) because of performance issues. Now I need this method to fix an issue with the "unique" (distinct) filter. When using "unique", a HSQLDB limitation [1] forces us to put the columns present in the "order by" clause in the "select" clause. This currently causes a lot of queries to fail when using the "unique" filter. The fix consists to add the columns from the "order by" clause in the "select" clause and then to remove the added columns from the query results. I think this new API fits well in the QueryResult interface, here's my +1. [1] This is considered invalid when backed by HSQLDB (and Oracle AFAIK): "select distinct doc.fullName from XWikiDocument order by doc.language" The reason is that the order can't be undoubtedly determined, for example with the following data: XWD_FULLNAME, XWD_LANGUAGE Main.Page1, de Main.Page1, fr Main.Page2, en Main.Page2, it -- Jean-Vincent Drean, XWiki.
