[xwiki-devs] [VOTE] XE 2.0 RC1 date change

by Vincent Massol

Hi, Some date change proposal since we're late on a few things: * RC1: move it to 24th of Aug (instead of 17th). It must contain: - bug fixes - All - distributed events done - Thomas - WYSIWYG changes for macro category - Marius - new skin: background + full horizontal width header + some CSS colors - Cati - watchlist working for XEM - JV * 2.0 final: 31st of Aug (unless we find critical bugs in RC1 in which case we'll do a RC2 and postpone the final to the 7th of Sep.) Here's my +1 Thanks -Vincent

[xwiki-devs] Sortable/Filterable tables

by Vincent Massol

Hi, I find it really not easy to use a sortable/filterable table in xwiki now + it exposes internals (like name and location of CSS and JS scripts): Syntax 1.0: $xwiki.ssfx.use("js/xwiki/table/table.css") $xwiki.jsfx.use("js/xwiki/table/tablefilterNsort.js", true) <table id="tableid" class="grid sortable filterable doOddEven"> .. </table> Syntax 2.0: {{velocity}} $xwiki.ssfx.use("js/xwiki/table/table.css") $xwiki.jsfx.use("js/xwiki/table/tablefilterNsort.js", true) {{/velocity}} {{html}} <table id="tableid" class="grid sortable filterable doOddEven"> .. </table> {{/html}} What's the best practice? How do we fix this quickly? (the longer fix is to implement either sorting/fitering at the syntax level using parameters or by introducing a new generic table/grid macro). Do we remove the documentation for this? (it's currently on the syntax page and broken since it doesn' t mention using ssfx/jsfx). Thanks -Vincent

[xwiki-devs] Problem with parametrized headers - Need CSS help

by Vincent Massol

Hi, Input: (% style="color:blue" %) = header = The result doesn't show the header in blue. The reason is that we have the following CSS in toucan: h1 span, h2 span, h3 span, h4 span { background-color:inherit; border-bottom:1px solid #CCCCCC; color:#000000; display:block; margin:20px 0; overflow:hidden; padding:0; position:relative; } It doesn't work since the style is set on h1 and the span's style is overidden in toucan's css. Question: Why don't we set the styles above on h1 instead of h1 span for ex? What can we do to fix this? I don't think that changing the XHTML renderer to set the style on the span would be a good thing. WDYT? Thanks -Vincent

[xwiki-devs] add new setProperty method to DocumentAccessBridge proposal

by Anamaria Stoica

Hi, Concerning DocumentAccessBridge [0], would it be possible to add another setProperty method, which would indicate the number(index) of the object you add the property value to? Its signature would be: void setProperty(String documentName, String className, int objectNumber, String propertyName, Object propertyValue) throws Exception; I need it to be able to easily add new objects and modify their property values, from a component. Is there any other way of doing this I overlooked? Right now, the only existing setProperty method operates only on the first object attached to the document: void setProperty(String documentName, String className, String propertyName, Object propertyValue) throws Exception; The corresponding getters are both already present: Object getProperty(String documentName, String className, int objectNumber, String propertyName); Object getProperty(String documentName, String className, String propertyName); WDYT? [0] - https://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-bridge/src/ma… Thanks, Anamaria

[xwiki-devs] [XOO] Images in XWiki pages

by Cristina Scheau

Hi everybody! Sorry for bother you again with my questions, but I have a problem that blocks me. I need to know what images are internal (they are attached to the current page or other XWiki page) in order to download them with my XMLRPC client. Using the rendering module I get every ImageBlock [1] and I check the ImageType[2] of every Image[3] object. My problem is that this type is URL for both external and internal images and that's why I can't cast to the DocumentImage class. I've pasted bellow my code and the output for some inputs. Can somebody tell me what I am wrong? Is there any other solution for getting the associated attachments? My client has these methods for getting the attachment data: - Attachment<http://confluence.atlassian.com/display/DOC/Remote+API+Specification#Remote…> getAttachment(String token, String pageId, String fileName, String versionNumber) - get information about an attachment. - byte[] getAttachmentData(String token, String pageId, String fileName, String versionNumber) - get the contents of an attachment. - byte[] getAttachmentData(Attachment attachment) - get the contents of an attachment. My code: // Parse Parser parser = ecm.lookup(Parser.class, syntax.toIdString()); XDOM xdom = parser.parse(new StringReader(source)); for (ImageBlock block : xdom.getChildrenByType(ImageBlock.class, true)) { Image image = block.getImage(); System.out.println(image.getType() + ""); System.out.println(image.getName() + ""); } Tests: Input: source: [[image:IMG3219.JPG]] image:http://www.balsamiq.com/images/xwiki_logo.png Syntax : XWIKI_2_0 Output: URL IMG3219.JPG URL http://www.balsamiq.com/images/xwiki_logo.png Input: source: <p><img src="IMG3219.JPG" alt="IMG3219.JPG"/><br/><br/><img src=" http://www.balsamiq.com/images/xwiki_logo.png" class="wikimodel-freestanding" alt=" http://www.balsamiq.com/images/xwiki_logo.png"/></p> syntax: XHTML_1_0 Output: URL IMG3219.JPG URL http://www.balsamiq.com/images/xwiki_logo.png Links: [1] http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rendering/xwik… [2] http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rendering/xwik… [3] http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rendering/xwik… Best regards, Cristina

[xwiki-devs] [VOTE] Rendering API change: move Syntax classes to syntax package

by Vincent Massol

Hi, I'd like to move syntax-related classes to org.rendering.syntax package. These are: - Syntax - SyntaxFactory - SyntaxType Right now they are in the org.rendering.parser package but that's not right since Syntax classes are used in Listeners, Parsers, Transformations, etc which are all top level rendering packages. This will break the API and is not backward compatible (for those using the rendering api directly) which is why I'd like to do this ASAP so that it's in XE 2.0 (which doesn't have to be backward compatible). Note that we already have lots of api breakage for the rendering module: <exclude>org/xwiki/rendering/listener/chaining/ AbstractChainingListener</exclude> <exclude>org/xwiki/rendering/renderer/EventsRenderer</ exclude> <exclude>org/xwiki/rendering/renderer/ PlainTextRenderer</exclude> <exclude>org/xwiki/rendering/renderer/TexRenderer</ exclude> <exclude>org/xwiki/rendering/renderer/XHTMLRenderer</ exclude> <exclude>org/xwiki/rendering/renderer/ XWikiSyntaxRenderer</exclude> <exclude>org/xwiki/rendering/renderer/ PrintRendererFactory</exclude> <exclude>org/xwiki/rendering/renderer/PrintRenderer</ exclude> <exclude>org/xwiki/rendering/renderer/chaining/ AbstractChainingPrintRenderer</exclude> <exclude>org/xwiki/rendering/renderer/xhtml/ DefaultXHTMLImageRenderer</exclude> <exclude>org/xwiki/rendering/renderer/xhtml/ DefaultXHTMLLinkRenderer</exclude> <exclude>org/xwiki/rendering/renderer/xhtml/ XHTMLRendererFactory</exclude> <exclude>org/xwiki/rendering/util/RenderersUtils</ exclude> <exclude>org/xwiki/rendering/parser/SyntaxFactory</ exclude> <exclude>org/xwiki/rendering/renderer/xhtml/ XHTMLImageRenderer</exclude> <exclude>org/xwiki/rendering/renderer/xhtml/ XHTMLLinkRenderer</exclude> <exclude>org/xwiki/rendering/parser/SyntaxType</ exclude> <exclude>org/xwiki/rendering/macro/descriptor/ MacroDescriptor</exclude> <exclude>org/xwiki/rendering/renderer/printer/ MonitoringWikiPrinter</exclude> <exclude>org/xwiki/rendering/configuration/ RenderingConfiguration</exclude> <exclude>org/xwiki/rendering/macro/MacroManager</ exclude> <exclude>org/xwiki/rendering/block/MacroBlock</exclude> <exclude>org/xwiki/rendering/macro/AbstractMacro</ exclude> <exclude>org/xwiki/rendering/macro/descriptor/ AbstractMacroDescriptor</exclude> <exclude>org/xwiki/rendering/macro/descriptor/ DefaultMacroDescriptor</exclude> <exclude>org/xwiki/rendering/block/ PlainTextBlockFilter</exclude> <exclude>org/xwiki/rendering/util/ParserUtils</exclude> This will add some more.

[xwiki-devs] Improve performance with new sun hotspot optimizations for Java 6u14?

by Niels Mayer

The latest Sun JDK 6 <http://java.sun.com/javase/6/webnotes/6u14.html> has optional performance optimization for threading. Since Xwiki running in a web-container is thread-intensive, I'm wondering whether performance improvements like Escape Analysis<http://en.wikipedia.org/wiki/Escape_analysis> will be noticed for Xwiki. How about for its increasing amount of work happening out of Groovy scripts? Much attention has been given by Sun, IBM, BEA and others to optimize lock > management and synchronization in their respective Java 6 virtual machine > offerings. Features like biased locking, lock coarsening, lock elision by > escape analysis and adaptive spin locking are all designed to increase > concurrency by allowing more effective sharing amongst application threads. http://www.infoq.com/articles/java-threading-optimizations-p1 http://www.infoq.com/articles/java-threading-optimizations-p2 http://blog.xebia.com/2007/12/21/did-escape-analysis-escape-from-java-6/ http://blog.xebia.com/2009/02/18/jvm-threading-optimizations-revisited/ http://blog.juma.me.uk/2008/12/17/objects-with-no-allocation-overhead/ <http://blog.xebia.com/2007/12/21/did-escape-analysis-escape-from-java-6/> http://java.dzone.com/articles/escape-analysis-java-6-update <http://java.dzone.com/articles/escape-analysis-java-6-update> Niels http://nielsmayer.com PS: I need to try this experiment again with the non-early access version http://nielsmayer.com/xwiki/bin/view/fedora10/64bitJavaAppletIn64BitFirefox… PPS: in clojure land (will this also apply to Groovy?) http://www.mail-archive.com/clojure@googlegroups.com/msg17221.html > > I'm getting a very significant performance improvement by adding a couple > of JVM parameters (using jdk 1.6.0_14).

MathTran is, by far, much better performing. Moreover, the infrastructure used has proven to be able to solve the baseline stuffs, for this, one needs the pictures to be delivered from the same server so that the javascript reads the PNG headers(!). Note that the option of TeX compilation that MathTran needs seems shipped for everyone although J Fine said it was not. If you are caching, it would make the remote problem almost trivial. > Oh, another minor problem is that it uses a variant of the TeX > syntax, not LaTeX. that is the major issue probably.

[xwiki-devs] Contributing to dutch translation

by Henk Schouten

Hello, I have a few questions about how to contribute to the dutch application_resource file. Yesterday I have added some translations to the dutch translation of the XE resources at the I10n.wiki.org site. Is there any documentation about this site? I am unsure about what some functions do and the effects they may have on others. For instance the link 'Import/reimport default language file', Admin actions like 'Import' and 'Prepare'. Also I noticed that when I get the dutch translation as a application resource file, it only has the resources filled in if a dutch translation exists. This seems logical, but as long as not all strings have a dutch translation, my xwiki contains lots of empty strings. Is there a way to build a resource file with dutch translations where available, and the default english strings when not? Another thing that is not clear to me is the functionality around reviewing and validation. If I find a translation that is incorrect of I thing there is a better one, can I just change it, or should I somehow make a review request to somebody authorized to accept or reject the change? Is there any way to know who is contributing to the same translation in order to achieve some common ideas about how to translate xwiki terms? Thanks, Henk -- == Henk F.

[xwiki-devs] Problems accessing DocumentAccessBridge from the XWiki implementation for Shindig PersonService

by Anamaria Stoica

Hi, In order to integrate Shindig with the XWiki datastore, 4 interfaces have to be implemented: PersonService, AppDataService, ActivityService and MessagesService (javadocs here [0]). To this end, I have created the xwiki-social-opensocial module [1]. While implementing PersonService (PersonServiceXW - [2]), I have encountered the following problem: As I needed to access the datastore, I also made PersonServiceXW a XWiki Component in order to gain access to the DocumentAccessBridge Component. BUT, here is the problem, the DocumentAccessBridge never gets initialized and at runtime is null. The reason this might happen, as Sergiu suggested, is that Shindig uses Guice to bind the services implementations in its code, thus the PersonServiceXW component never gets to be registered with XWiki's Component Manager. My question is how do I get data in and out XWiki's datastore from the PersonService implementation, if I cannot use the DocumentAccessBridge this way? Can it be registered to the Component Manager somehow, or is there a completely different way this could be achieved? I will continue with some integration details (about the patch on xwiki-web-standard and the OpenSocial XWiki Application). At the end I included some instructions on how to build and test them. ***xwiki-web-standard patch (apply on xwiki-platform-web), consisting of: - in standard/src/main/webapps/templates: * added 3 .vm files which handles getting/adding/deleting friends: addfriend.vm, getuserfriends.vm, deletefriend.vm - in standard/src/main/webapps/resources/xwiki/opensocial: * added javascript and css files necessary for the Shindig container - in standard/src/main/webapps/WEB-INF: * modified web.xml to include all shindig servlet mappings and necessary Guice modules - in standard/src/main/webapps/WEB-INF/classes: * added container/default/container.js and shindig.properties - default Shindig container configurations. I put them in the classpath as they required modifications from the original files - in standard: * modified pom.xml, to include as a dependency xwiki-social-opensocial module ***Open Social XWiki Application, consisting of: - OpenSocial.GadgetContainerClass - the simplest OpenSocial Gadget container; has a single url property (the url of the gadget); in view mode it displays/renders it - OpenSocial.GadgetContainerClassSheet - OpenSocial.GadgetContainerClassTemplate - OpenSocial.HelloWorld - hello world Gadget (only displays a String) - NO OpenSocial features - works - OpenSocial.LabpixiesTodo - Gadget with NO OpenSocial features 1 - works - OpenSocial.Horoscope - Gadget with NO OpenSocial features 2 - works - OpenSocial.ListFriends - SHOULD list the friends of the currently logged in user. The friends are retrieved using the XWiki implementation of the Shindig's PersonService, which is located in the xwiki-social-opensocial module (PersonServiceXW). The service TRIES to use DocumentAccessBridge component in order to retrieve the necessary data from the XWiki datastore. - OpenSocial.TestingGadgetsSource - used to attach gadgets XML files to the page. Their URLs can be used for GadgetContainerClass objects (e.g. ListFriends gadget) - Panels.My Friends - panel, displays the friends of the currently logged in user - Panels.Navigation - XWiki.FriendClass - A friend; objects of this type can be attached to user profiles; has as a single property friendName, which contains the name of the friend - XWiki.FriendClassSheet - XWiki.FriendClassTemplate - XWiki.XWikiUserSheet - to add the list of friends to profile - XWiki.MyResources - XWiki.XWikiPreferences Instructions for testing (one possible way at least): 1. Patch xwiki-platform-web (changes are only in xwiki-web-standard), with the patch from JIRA - [3] 2. Build xwiki-web-standard 3. Build xwiki-enterprise in offline mode (-o), so it will use xwiki-web-standard from the local repository build at step 2 4. Run XWiki Enterprise. I always use xwiki-enterprise-jetty-hsqldb-2.0-SNAPSHOT from the generated distributions 5. Import opensocial XAR - [4] What to look for while testing (working stuff): - Gadgets: - see all/add new gadgets http://localhost:8080/xwiki/bin/view/OpenSocial/GadgetContainerClass - http://localhost:8080/xwiki/bin/view/OpenSocial/HelloWorld - http://localhost:8080/xwiki/bin/view/OpenSocial/LabpixiesTodo - http://localhost:8080/xwiki/bin/view/OpenSocial/Horoscope - http://localhost:8080/xwiki/bin/view/OpenSocial/ListFriends (social features) --> as specified before, not working - While you're here, you could also: - Log in as Alice (password 'alice') - Go to profile page and edit friends list; You should have 2 friends: Jane and Bob (they have as passwords 'jane', and 'bob') - See My Friends Panel, with the friends of the current logged in user displayed [0] - http://incubator.apache.org/shindig/shindig-1.1.x/apidocs/org/apache/shindi… [1] - https://svn.xwiki.org/svnroot/xwiki/sandbox/gsoc/opensocial/xwiki-social-op… [2] - https://svn.xwiki.org/svnroot/xwiki/sandbox/gsoc/opensocial/xwiki-social-op… [3] - http://jira.xwiki.org/jira/browse/XSANDBOX-36?focusedCommentId=43674&page=c… [4] - http://jira.xwiki.org/jira/browse/XSANDBOX-64?focusedCommentId=43675&page=c… Other helpful links: - Guice module configuration for my service implementations https://svn.xwiki.org/svnroot/xwiki/sandbox/gsoc/opensocial/xwiki-social-op… - Exemple of PersonService being injected by Guice in Shindig's code http://svn.apache.org/repos/asf/incubator/shindig/trunk/java/social-api/src… Thanks, Anamaria

Hi, Please give feedback on the menu iteration. You can view the mockups at http://incubator.myxwiki.org/xwiki/bin/view/Improvements/Skin20Menu 1. We need to decide the way we handle the actions we are able to do (depending on the rights we have): enable/disable them or hide them. 2. You can select to have an simple or advanced menu (View and Edit submenus affected) Thanks, Caty

[xwiki-devs] [VOTE] Move remote observation manager from sandbox to core

by Thomas Mortagne

Hi devs, I would like to introduce a first partial beta of the event network distribution system in the 2.0M3. Note that the module itself is complete what will need to be done with debugging is making everything in core use the new Observation Manager instead of the old notification service. For this release i plan to: - add the remote observation manager module (disabled by default) - implement a EventConverter for documents events (event convert has a generic converter for Serializables events but documents converted has XWikiDocument and XWikiContext we want to filter before sending it to the network). - make XWiki cache store listen to remote doc event to invalidate the cache accordingly (this is the main thing that will bring event based clustering support to XWiki, all the rest is already supposed to update its cache based on events remote or not) Here is my +1 -- Thomas Mortagne

Re: [xwiki-devs] Blog Wiki 2.0 Upgrade 7th Draft

by Andreas Schaefer

Hi I know that we all volunteer for this project and so this is not a critic of anybody's work but I have to say that the Feed Plugin has more holes than a Swiss cheese and I should know. I could work around all the issues but now the SyndEntryDocumentSource class does not render Wiki 2.0 code (hard coded to 1.0). There is also an issue where the conversion of Categories fails in the Rome Converters because the Categories is a String but the Rome expects a SyncdCategory. The only conversion that works so far is atom_0.3. One of the problems I see with the Feed Plugin is that the test suite is not sufficient and therefore many of the method now fail in 2.0. I would volunteer to help to build it if someone could show me to how to setup a test environment where I could execute the Feed Plugin against (Blog first). Is there a plugin that tests against a mock up XWiki to make sure it is working? Cheers Andreas Schaefer
