[xwiki-devs] PGSQL/hibernate problem while importing DOC document (value too long)
by Karel Gardas 29 Nov '11

29 Nov '11

Hello, while trying to import Word document (non trivial) I'm hitting an issue where underlaying PostgreSQL complains about value too long to be stored. The message (cut from the console) looks as: SQL next exception = [org.postgresql.util.PSQLException: ERROR: value too long for type character varying(200000)]] Actual exception looks like: XWD_VERSION='2.1', XWD_CUSTOM_CLASS='', XWD_PARENT='', XWD_CLASS_XML='', XWD_ELEMENTS='0', XWD_DEFAULT_TEMPLATE='', XWD_VALIDATION_SCRIPT='', XWD_COMMENT='Created by office importer.', XWD_MINOREDIT='0', XWD_SYNTAX_ID='xwiki/2.0', XWD_HIDDEN='0' where XWD_ID='-408553786' was aborted. Call getNextException to see the cause. at org.postgresql.jdbc2.AbstractJdbc2Statement$BatchResultHandler.handleError(AbstractJdbc2Statement.java:2598) ~[postgresql-9.0-801.jdbc4.jar:na] at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1836) ~[postgresql-9.0-801.jdbc4.jar:na] at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:407) ~[postgresql-9.0-801.jdbc4.jar:na] at org.postgresql.jdbc2.AbstractJdbc2Statement.executeBatch(AbstractJdbc2Statement.java:2737) ~[postgresql-9.0-801.jdbc4.jar:na] at org.apache.commons.dbcp.DelegatingStatement.executeBatch(DelegatingStatement.java:297) ~[commons-dbcp-1.3.jar:1.3] at org.apache.commons.dbcp.DelegatingStatement.executeBatch(DelegatingStatement.java:297) ~[commons-dbcp-1.3.jar:1.3] at org.apache.commons.dbcp.DelegatingStatement.executeBatch(DelegatingStatement.java:297) ~[commons-dbcp-1.3.jar:1.3] at org.hibernate.jdbc.BatchingBatcher.doExecuteBatch(BatchingBatcher.java:48) ~[hibernate-3.2.6.ga.jar:3.2.6.ga] at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:246) ~[hibernate-3.2.6.ga.jar:3.2.6.ga] ... 137 common frames omitted this is XWiki 3.1 enterprise with few our custom patches but they are not related to the storage nor import functionality, so I guess we've not broken this ourself. Do you have any idea how to workaround this issue or even how to properly fix it? Thanks a lot! Karel

[xwiki-devs] [CONTRIB] Panel Macro
by Guillaume Sauthier (Objectweb) 29 Nov '11

29 Nov '11

Hi all It's a following of the recent discussion on this list :) I have provided the basis for a java backed {{panel}} macro implementation. The source code is currently hosted on my github account, but I would like to move it under xwiki-contrib. See https://github.com/sauthieg/xwiki-panel-macro I've inited an extension page for this macro on the extension wiki: http://extensions.xwiki.org/xwiki/bin/view/Extension/Panel+Macro BTW, what is the type for a Java Macro ? Macro type seems to be restricted to Velocity ... Any interest ? --G

Hi, The component writing tutorial seems outdated at http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents The dependencies seems to not exist anymore <dependencies> <dependency> <groupId>org.xwiki.platform</groupId> <artifactId>xwiki-core-component-default</artifactId> <version>${platform.core.version}</version> </dependency>  <dependency> <groupId>org.xwiki.platform</groupId> <artifactId>xwiki-core-shared-tests</artifactId> <version>${platform.core.version}</version> <scope>test</scope> </dependency> </dependencies> Should the first one be: xwiki-platform-component-multi and xwiki-platform-test ? -- Ludovic Dubost Founder and CEO Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost

[xwiki-devs] Java Panel Macro Contribution
by Guillaume Sauthier (Objectweb) 28 Nov '11

28 Nov '11

Hi all Some weeks ago, I've been discussing in IRC with Thomas and Vincent about contributing a {{panel}} macro that could be used to replace the old velocity #panelHeader()/#panelFooter() macro... I've pushed that code into github : https://github.com/sauthieg/xwiki-panel-macro ATM, it probably has less features than the old velocity stuff, but I'm sure it is a good starting point if you want to move to a Java-based panel macro. The code is tested using the XWiki Test Runner. So if you're interested in that code, I'll be happy to re-contribute it to XWiki. Any thoughts ? --Guillaume

[xwiki-devs] [idea] Need link to sheet when editing a page which is displayed by a sheet
by Vincent Massol 28 Nov '11

28 Nov '11

Hi (Marius), With the new powerful sheet system it's now very hard to know where is located the sheet used to display the page (it's magical now ;)). Thus I think that when editing a page in wiki/wysiwyg edit modes we need to display a link to edit the sheet used to display the page, in the Document Information panel. WDYT? Thanks -Vincent

[xwiki-devs] Call for review thread safety new Component Manager
by Thomas Mortagne 28 Nov '11

28 Nov '11

Hi guys, I'm trying to reduce the enormous number of lock done by the current implementation of Embedded Component Manager and I could use some more brains to check what I did. You can find the new version on https://github.com/xwiki/xwiki-commons/blob/feature-improvecm/xwiki-commons… Quick comparison with the current one: * removed all "synchronized (this)" that was in pretty much all the methods and which made the CM block everything whenever anyone was using it * used ConcurrentHashMap to securize the insertion/search of components * basically the only remaining explicit lock is on singleton component initialization mostly to make sure we don't initialize the same component at the same time If you find some small modification to improve a bit the speed don't hesitate too. There is possible improvements to speed up lookuplist and lookupmap (not going though the whole map basically) but it require important refactoring and I would prefer not doing too much things at once since it's a pretty critical peace of code and locking is the main issue right now. Thanks, -- Thomas Mortagne

[xwiki-devs] [Proposal] Adding the notion of Priority to Event Listeners
by Vincent Massol 25 Nov '11

25 Nov '11

Hi devs, Summary: ======== I'd like to add the notion of Priority to Event Listeners. The reason is that in some cases it's important that some listeners execute before others. The problem at hand: ================= Here's a typical use case: When receiving the ApplicationStartedEvent, we have lot of code that needs to initialize. Initialization order is important (you can compare it to run levels in OS): for example some init must happen after the Database initialization has happened. Note that another solution exists for this use case: some initializations could introduce their own events (such as a DatabaseStartedEvent) and other init could listen on those events instead of the generic ApplicationStartedEvent. However I can see several drawbacks to this: * it's less generic than the priority solution * it means creating more events * but more importantly it means that modules will have strong dependencies (at maven level) on each other whereas it's not necessary and shouldn't be the case. In our example use case: it means that inits that must happen after database is started will need to depend on oldcore (which is where DB is started ATM) Proposal: ======== * Don't break backward compat in Observation module * Introduce a PrioritizedEventListener interface that adds a getPriority() method * Modify ObservationManager implementation to take into account priorities * In order to make it simple I propose to have only a single priority per Listener and not a priority per event supported by a given listener General Context ============= To give some context here's what I'd like to do on the medium term: * Step 1: Introduce notion of priority in EventListeners * Step 2: Refactor XWiki init to use an EventListener on AppStarted with low priority * Step 3: Refactor wiki macros to use an EventListener on AppStarted with priority value lower than at step2 * Step 4: Write an EventListener for the new UI Extensions with a priority value higher than the one of step2 <-- this is the initial goal that led me to make this proposal ;) WDYT? Thanks -Vincent

[xwiki-devs] How to load GWT application on Xwiki pages?
by Leon Wang 24 Nov '11

24 Nov '11

Hi Everyone! I have read this document "Writing GWT applications in XWiki" ( http://dev.xwiki.org/xwiki/bin/view/Drafts/WritingGWTApplicationsInXWiki) And I know how to develop GWT module for xwiki now. I also have read the document "WYSIWYG Editor Module" ( http://code.xwiki.org/xwiki/bin/view/Modules/WysiwygEditorModule) I followed the instruction which tried to integrate the WYSIWYG editor(GWT application) in wiki pages, and I put the following code in my wiki editor: "{{html}} <script type="text/javascript" src="XWikiWysiwyg.js"> alert('WYSIWYG code is loaded!'); </script> <textarea id="demo"></textarea> <script type="text/javascript"> Wysiwyg.onModuleLoad(function() { new WysiwygEditor({hookId:'demo'}); alert('WYSIWYG code is loaded!'); }); Wysiwyg.onModuleLoad(function() { editor = new WysiwygEditor({hookId: 'demo'}); }); }); </script> {{/html}}" After saved, it only display a blank text area without any sign of WYSIWYG editor, also there is no alart 'WYSIWYG code is loaded!' popup. Can you help me figure it out what is wrong with it? I am planing to develop a tree view using GWT to display Design Rationale Element. Could you give me some ideas of after my development, how can I embeded the GWT application into Xwiki pages and interact with the GWT application? Thank you very much! Leon
