[xwiki-devs] how to debug an empty stack in DefaultDocumentAccessBridge?

by Paul Libbrecht

Hello XWiki experts, in Curriki, we met a bug that seems related to the wysiwyg editor's ability to accept html. When it does so, and is input with an image, it fails the html conversion because of the exception below for the simple (cleaned) content: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html><head></head><body><p>Image</p><p><img alt="sunset-dark2.PNG" src="http://node1.hoplahup.net/xwiki/bin/download/AssetTemp/dgW1kVv9l2mE9xqA/sun…"></img></p></body></html> Yielding the exception: Caused by: java.lang.NullPointerException: null at com.xpn.xwiki.doc.DefaultDocumentAccessBridge.getContext(DefaultDocumentAccessBridge.java:85) ~[xwiki-platform-legacy-oldcore-3.5.1.jar:na] at com.xpn.xwiki.doc.DefaultDocumentAccessBridge.getAttachmentURL(DefaultDocumentAccessBridge.java:847) ~[xwiki-platform-legacy-oldcore-3.5.1.jar:na] at org.xwiki.rendering.internal.wiki.XWikiWikiModel.getLinkURL(XWikiWikiModel.java:137) ~[xwiki-platform-rendering-xwiki-3.5.1.jar:na] at org.xwiki.rendering.internal.wiki.XWikiWikiModel.getImageURL(XWikiWikiModel.java:153) ~[xwiki-platform-rendering-xwiki-3.5.1.jar:na] at org.xwiki.rendering.internal.renderer.xhtml.image.DefaultXHTMLImageRenderer.onImage(DefaultXHTMLImageRenderer.java:120) ~[xwiki-rendering-syntax-xhtml-3.5.1.jar:na] at org.xwiki.rendering.internal.renderer.xhtml.XHTMLChainingRenderer.onImage(XHTMLChainingRenderer.java:545) ~[xwiki-rendering-syntax-xhtml-3.5.1.jar:na] at org.xwiki.rendering.listener.chaining.AbstractChainingListener.onImage(AbstractChainingListener.java:454) ~[xwiki-rendering-api-3.5.1.jar:na] at org.xwiki.rendering.listener.chaining.AbstractChainingListener.onImage(AbstractChainingListener.java:454) ~[xwiki-rendering-api-3.5.1.jar:na] at org.xwiki.rendering.listener.chaining.EmptyBlockChainingListener.onImage(EmptyBlockChainingListener.java:600) ~[xwiki-rendering-api-3.5.1.jar:na] at org.xwiki.rendering.listener.chaining.AbstractChainingListener.onImage(AbstractChainingListener.java:454) ~[xwiki-rendering-api-3.5.1.jar:na] at org.xwiki.rendering.listener.chaining.BlockStateChainingListener.onImage(BlockStateChainingListener.java:796) ~[xwiki-rendering-api-3.5.1.jar:na] I am not too sure how to debug that.

[xwiki-devs] Docker XWiki

by Fabio Mancinelli

Hi all, since I wanted to better understand how Docker works, as an evening project I created a Dockerfile for packaging an image that can be used to run an XWiki container. It also supports data persistence, so that you don't lose your data when you shut down the container. You can find it here: https://github.com/fmancinelli/docker-xwiki Enjoy, Fabio

[xwiki-devs] [Proposal] Automatic creation of objects with HTTP parameters

by Jean SIMARD

Hi devs, In XWiki, if you send a POST request at the following URL ('MySpace.MyPage' is a document that doesn't exist at the moment) /bin/save/MySpace/MyPage with the following HTTP parameters: * template=MySpace.MyTemplate * XWiki.XWikiRights_0_users=XWiki.Me * <others parameters> with 'MySpace.MyTemplate' a template document and 'XWiki.Me' a user of the wiki. 2 cases: 1. If 'MySpace.MyTemplate' contains a 'XWiki.XWikiRights' object, then the resulting document 'MySpace.MyPage' will have this object with its property 'users' initialize with the value 'XWiki.Me' (see HTTP parameters) 2. If 'MySpace.MyTemplate' does not contain a 'XWiki.XWikiRights' object, the resulting document 'MySpace.MyPage' will not contain it either ### PROPOSAL Create automatically the objects if they don't exist in the template document. ### To make it possible, it seems that we would need to refactor the method 'readObjectsFromForm(EditForm, XWikiContext)' in the 'com.xpn.xwiki.doc.XWikiDocument' class. And probably modify also the 'getObject(String)' from 'com.xpn.xwiki.web.EditForm' class. 2 things to take care: * It seems there is no unit test for these methods. * May this proposal be a security problem? WDYT? -- Jean
