[xwiki-devs] [Brainstorming] Hiding technical content
by Vincent Massol 23 Mar '12

23 Mar '12

Hi devs, I've been brainstorming with Jean-Vincent about how to implement hiding technical content for 4.0. Here's what we would like to do: Note: This is related to the proposal I made earlier: http://markmail.org/thread/jupn22fdk4nnqj6p In summary: * Add a RoleVisibilityClass XObject to documents and spaces (in WebPreferences for Spaces) which is a list of Roles (simple or advanced users for now) deciding which role should be allowed to view a given document in result sets. * Either modify XWikiHibernateStore or introduce a new FilteredHibernateStore store which would delegate to XWikiHibernateStore (same mechanism as the cache store) to add the JOIN to check the visibility and only return visible documents for the current user * Remove the notion of hidden documents and have a migrator to remove the column in xwikidocs * Modify the Lucene plugin to add a VISIBILITY field and return filtered results based on the visibility and the current user role * Note1: After much brainstorming we think that the notion of "application" could be implemented either with an Application XObject that tie the document to an application or with an Application Descriptor. * Note2: We'll need to decide at some point if we want more roles than just "simple user" and "advanced user" and if we need "developer" and "admin" too. * Notes1 and 2 are currently out of scope for this proposal However we're wondering how much performance we will loose with this implementation using XObjects (due to the extra JOIN). Do you think it's acceptable? Could it be improved with custom mapping? (I think not) Should we implement this without XObjects and instead modify XWikiDocuments and add a new column in xwikidocs? Thanks -Vincent

[xwiki-devs] Trouble Building XWiki-enterprise
by Craig Innes 22 Mar '12

22 Mar '12

Hi, As suggested by Marius and Ecaterina, i have downloaded the XWiki-enterprise JAR file to install it and play around with it a little. A have also cloned the git repo and installed maven in an attempt to build from source. However, when i run mvn install in the source folder i get the following error: [ERROR] Failed to execute goal org.xwiki.platform:xwiki-platform-tool-packager-plugin:4.0-SNAPSHOT:import (default) on project xwiki-enterprise-database-hsqldb: Execution default of goal org.xwiki.platform:xwiki-platform-tool-packager-plugin:4.0-SNAPSHOT:import failed: Plugin org.xwiki.platform:xwiki-platform-tool-packager-plugin:4.0-SNAPSHOT or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.opensymphony.quartz:quartz:jar:1.6.5, org.suigeneris:jrcs.diff:jar:0.4.2, org.suigeneris:jrcs.rcs:jar:0.4.2, com.google:googleapi:jar:xwiki:UNKNOWN, info.informatica:css4j:jar:0.13, info.informatica:jclf:jar:2.3.0, jtidy:jtidy:jar:8.0-20060801.131059-3-dev, org.codehaus.swizzle:swizzle-confluence:jar:xwiki:1.2-20080419, com.yahoo.platform.yui:yuicompressor:jar:2.4.2-xwiki, edu.emory.mathcs.util:emory-util-classloader:jar:2.1, edu.emory.mathcs.util:emory-util-io:jar:2.1, edu.emory.mathcs.util:emory-util-security:jar:2.1, uk.ac.ed.ph.snuggletex:snuggletex-core:jar:1.1.0, uk.ac.ed.ph.snuggletex:snuggletex-jeuclid:jar:1.1.0, org.infinispan:infinispan-core:jar:5.1.1.FINAL, org.artofsolving.jodconverter:jodconverter-core:jar:3.0-beta-4-xwiki-20110822, org.restlet.jse:org.restlet:jar:2.0.11, org.restlet.jee:org.restlet.ext.servlet:jar:2.0.11, org.restlet.jse:org.restlet.ext.jaxrs:jar:2.0.11: Could not find artifact org.opensymphony.quartz:quartz:jar:1.6.5 in central ( http://repo.maven.apache.org/maven2) -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[xwiki-devs] GSoC idea.
by Faryshta 21 Mar '12

21 Mar '12

Hi I would like to submit one idea for the GSoC this year. I have lots of experience on front end web development and I see that your generated HTML is somewhat messy. I can help with that. One of your ideas is Any Integration with one or more Major Open Source Tool<http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/AnyIntegrationwithaM…>' and my idea is to implement bootstraps on your code twitter.github.com/bootstrap/ which is a library of styles and presentation. Most web companies can't allow themselves a web designer AND a web developer so they use bootstraps as a way to solve both conflicts. Other idea is to integrate lesscss. What do you think? Thanks for reading.

[xwiki-devs] Information about GSoc Proposal: Wiki Browser
by Craig Innes 21 Mar '12

21 Mar '12

Hi, My name is Craig Innes. I am a 3rd year computing science student at Edinburgh University. I am interested in developing a nautillus-like UI for XWiki as part of the Google Summer of Code. Are there any mentors out there that can give me any more detail about what would be involved in this project? I have a sound knowledge of Java, CSS and HTML (as well as Python and a few other languages). Additionally, what are the things i should be doing before the applications open to get a feel for what to do/the subjects that i will need to learn? Cheers, Craig

[xwiki-devs] XWiki over HDFS?
by Mark Wallace 20 Mar '12

20 Mar '12

Has any work been done regarding XWiki over an HDFS file system or database? I saw a mention of Cassandra in an older post in this list, but I'm unclear on if Cassandra really runs over HDFS. -- Mark Wallace Principal Engineer, Semantic Applications Modus Operandi, Inc.

Just FYI, LDAP group mapping turned out to be quite popular topic. And XWiki has been referenced for implementation: http://jira.codehaus.org/browse/SONARPLUGINS-895 Their work is still in progress (right now they update plug-in documentation) but it looks like XWiki implementation is still better :) http://docs.codehaus.org/display/SONAR/LDAP+Plugin Regards, Roman -- View this message in context: http://xwiki.475771.n2.nabble.com/You-re-being-referenced-tp7388479p7388479… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] [Proposal] Add new Image macro to xwiki-platform
by Vincent Massol 19 Mar '12

19 Mar '12

Hi everyone, I'd like to propose to add an Image macro that would do the following: * display a border * display a caption (if it's defined by the user) * display a link to see the image full screen * define default sizes and scale it to the default one but allow specifying other sizes Basically the idea is to be able to easily display images as on http://en.wikipedia.org/wiki/Flora_and_fauna_of_Orissa See also http://jira.xwiki.org/browse/XWIKI-7602 The idea is that we would use it on xwiki.org but I also think it makes it nicer for people who wish to display images in their wikis. WDYT? Thanks -Vincent

[xwiki-devs] [VOTE] merge branch 'feature-user-profile-information-editor' into master in 4.0M2
by Eduard Moraru 19 Mar '12

19 Mar '12

Hi devs, I`ve worked on allowing an admin to more easily customize the information that is displayed on the user profile, once he has added some new fields to the XWikiUsers class (like "interests", "hobbies", "favorite books", etc). The first version is without javascript. Please have a look at the pull request [1] (and the issue [2]) and cast your vote whether we can merge it into master for 4.0M2 or not. Here's my +1. Thanks, Eduard ---------- [1] https://github.com/xwiki/xwiki-platform/pull/38 [2] http://jira.xwiki.org/browse/XWIKI-7626

[xwiki-devs] Employing the security manager
by Andreas Jonsson 19 Mar '12

19 Mar '12

Hi everyone! I have experimented with the Java security manager to see how it can be used to divide the XWiki platform into domains with different sets of privileges. My initial thought was that a customized security manager would be necessary, but I now think that the standard security manager is sufficient. But unless I have missed something, the policy file will necessarily be complex, because it is not possible to place jar-files in different subdirectories in a servlet and therefore wildcarding cannot be used in the policy file. But to simplify the policy management, I suggest using a tool at build-time to generate the policy file. More details about my thoughts on this can be found here: http://dev.xwiki.org/xwiki/bin/view/Drafts/Security+Manager By enabling the security manager like this, we can allow unprivileged users to write Groovy and Python scripts as well as reducing the risk that references to exploitable objects leak to unprivileged velocity scripts. I have already started working on a Maven mojo for generating the policy file, and I will shortly add a feature branch for this. Please, let me know what you think. Best Regards, /Andreas
