[xwiki-devs] [Proposal] Deprecation Day on 26th of April 2012

by Vincent Massol

Hi devs, I'd like to propose a Deprecation Day on the 26th of April 2012. The idea is that during this day all committers who would like to participate focus on moving deprecated APIs to legacy modules. At the end of the day we'll count how many deprecated API we've moved (each committer should keep tab of how many APIs he moves to make that count easy). Then we'll blog about it on xwiki.org WDYT? Thanks -Vincent

[xwiki-devs] Temp files for images with width param grow until JVM exit

by Jamie Maher

Hi there, I was testing out the XWiki Enterprise 3.5 release and I noticed that the temporary files folder under my Tomcat 7 kept growing while I was testing out XWiki. I had added a number of jpg attachments to a page that was using the {{photoalbum}} macro to display them. However, I found that this causes a number of download requests with the width parameter set, which seems to cause a new temporary file to be created for each request. It seems that even though the original image is cached it re-creates a new XWikiAttachmentContent thumbnail from those original bytes each time, causing multiple DiskFileItems to be created. Looking through the code for XWikiAttachmentContent it does set the deleteOnExit() for the DiskFileItem's store location file, but this file then will only be deleted when the JVM is shutdown. If multiple pages have many images each and they are being displayed in the photoalbum macro, then this creates a problem with diskspace being used up until the server is restarted. (And in my case for some reason stopping Tomcat via the service icon terminates the JVM in a way that doesn't cause the deleteOnExit() to be called as all of the temporary files are left behind after Tomcat is stopped) How can we stop all these temporary files from becoming a problem with a long running web application? There may be a better way, but I tried hacking around with the 3.5 platform on my github account and created a component to fix the problem by deleting files that had their DiskFileItem no longer being referenced: Modified 3.5 platform (mainly XWikiAttachmentContent) https://github.com/jamiemaher/xwiki-platform/tree/feature-tempfiles-3.5 Temporary Files provider component referenced by the XWikiAttachmentContent: https://github.com/jamiemaher/xwiki-tempfiles-component It seems to work pretty well, although there seem to be some files that don't seem to be reclaimed, although I haven't tracked down if it's because they are also in the regular xwiki cache as well. Thanks, Jamie

[xwiki-devs] [VOTE] Change our Maven POM Names and Description for Extension Manager

by Vincent Massol

Hi devs, Now that we're starting to use the Extension Manager (EM) we need to be careful about the Description and Names we use in our pom.xml since they're used by the EM to display information to the user. They're also used by the XR application to import extensions located in maven repository into extensions.xwiki.org (EXO). Right now our names are of the type shown here: https://gist.github.com/2311321 For example: [INFO] XWiki Commons - Extension - Parent POM ............ SUCCESS [0.004s] [INFO] XWiki Commons - Extension - API ................... SUCCESS [2.066s] [INFO] XWiki Commons - Extension - Handler - Parent POM .. SUCCESS [0.017s] [INFO] XWiki Commons - Extension - Handler - JAR ......... SUCCESS [0.133s] [INFO] XWiki Commons - Extension - Repository - Parent POM SUCCESS [0.004s] [INFO] XWiki Commons - Extension - Repository - Aether ... SUCCESS [0.132s] [INFO] XWiki Commons - Extension - Repository - XWiki .... SUCCESS [0.006s] [INFO] XWiki Commons - Extension - Repository - XWiki model SUCCESS [0.188s] [INFO] XWiki Commons - Extension - Repository - XWiki api SUCCESS [0.010s] [INFO] XWiki Commons - Extension - Repository - XWiki handler SUCCESS [0.024s] These names are not nice names for users. Actually they're more IDs than names. And having the users see those in our livetable on EXO isn't nice for example. Nor is it nice if they see them in the EM UI. I thus propose that we change the way we use names in our pom.xml to use English-readable names, without any "XWiki" prefix. For example, for the example show above we could have: Extensions Extension API Extension Handlers JAR Extension Handler Extension Repositories Aether Extension Repository XWiki Extension Repository XWiki Extension Repository Model XWiki Extension Repository API XWiki Extension Repository Handler The alternative is to introduce a custom property in our pom.xm that would be used by the EM and XR but that's not a good solution because it means even more maintenance work. While not using technical id as names in our pom.xml is not as nice when displayed in the Maven Reactor I feel it's still the best solution we have. Here's my +1 Thanks -Vincent

[xwiki-devs] [UX][Proposal] Improving Homepage Content

by Ecaterina Moraru (Valica)

Hi devs, I've made a proposal with some suggestions on what we can change on the Homepage. http://incubator.myxwiki.org/xwiki/bin/view/Improvements/HomepageContent The proposal is divided in Homepage Content improvements and Dashboard improvements (that still need some work). The Homepage improvements contains things like: - Improved Welcome message (a link to the Getting Started guide has already been added) http://incubator.myxwiki.org/xwiki/bin/download/Improvements/HomepageConten… You can see this in action on http://incubator.myxwiki.org/xwiki/bin/view/Main/WebHome This proposal would imply adding other 3 external links to: http://platform.xwiki.org/xwiki/bin/view/Features/DocumentLifecycle http://platform.xwiki.org/xwiki/bin/view/Features/PageEditing http://extensions.xwiki.org/xwiki/bin/view/Extension/Index+Application IMO these documentation pages contain valuable information and would also educate the user on how to make use of xwiki.org. - Implement mechanism to hide technical content (in progress by JV) - Simplify the 'Tags' section initial text http://jira.xwiki.org/browse/XWIKI-7678 - Separate Message Stream input from Activity Stream http://jira.xwiki.org/browse/XWIKI-7679 The Dashboard improvements contains: - Improve gadget's container styling in INLINE mode to better suggest dragging and delimitation http://jira.xwiki.org/browse/XWIKI-7681 Please share your thoughts about these ideas. Thanks, Caty

[xwiki-devs] CLIRR reports and moved modules

by Sergiu Dumitriu

Hi devs, I noticed that no CLIRR errors are generated for modules that have been moved from platform to commons. This isn't good, since we're not reporting all the API breakages. I propose that whenever a module is moved, we add a special configuration for the maven clirr plugin in that module's pom.xml file, so that it compares with the previous version with the platform groupId. See http://mojo.codehaus.org/clirr-maven-plugin/examples/specific-artifacts.html for more details about the required configuration. -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] Including jquery javascript library issues

by du du

Hi, all, I got a strange problem, whenever I include the jquery script in my vm file like this: <script type="text/javascript" src="/xwikim/bin/skin/resources/JScripts/jQuery/slickgrid/lib/jquery-1.7.min.js"></script> I got the following exception; I thought it caused by jquery and prototype conflict, but I included <script type="text/javascript"> jQuery.noConflict(); var $j = jQuery; </script> replaced $ for jquery with $j, but the same error, I also tried to use $xwiki.jsfx.use(), still same, any solution for this?

[xwiki-devs] Logging problem

by du du

Hi, all, I have the following logback.xml file, I developed a servlet, and used common logging library, import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; Log logger = LogFactory.getLog(FileTestServlet.class); I also added this to the logback.xml: <logger name="next.filetest" level="debug"/> In the code, I have the following code: logger.debug("FileTestServlet doGet..."); But in the xwiki.log file, the message is not logged to the log file, anything wrong? I tried to configure log4j.properties in the classes folder, used log4j logger for logging, there is no message logged either. Thanks for your help. Dave <configuration> <appender name="xwiki" class="ch.qos.logback.core.rolling.RollingFileAppender">  <file>C:\apache-tomcat-7.0.25\logs\xwiki.log</file> <append>false</append> <encoder> <pattern>%d [%t] %-5p %c - %m%n</pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <maxIndex>10</maxIndex> <FileNamePattern>C:\apache-tomcat-7.0.25\logs\xwiki.log.%i</FileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>5MB</MaxFileSize> </triggeringPolicy> </appender> <logger name="com.xpn.xwiki.render.XWikiRadeoxRenderEngine" level="warn"/> <logger name="org.apache.fop.layoutmgr.inline.ContentLayoutManager" level="error"/> <logger name="org.apache.struts.util.RequestUtils" level="error"/> <logger name="org.hibernate.type" level="warn"/> <logger name="com.xpn.xwiki.store.migration" level="info"/> <logger name="org.hibernate.SQL" level="debug"/> <logger name="org.jgroups" level="error"/> <logger name="org.hibernate" level="warn"/> <logger name="info.informatica.doc.style.css.dom" level="error"/> <logger name="org.hibernate.ps.PreparedStatementCache" level="warn"/> <logger name="org.xwiki" level="info"/> <logger name="com.xpn.xwiki" level="warn"/> <logger name="next.filetest" level="debug"/> <root level="DEBUG"> <appender-ref ref="xwiki"/> </root> </configuration>

[xwiki-devs] [Proposal] XWiki 4.x Cycle Themes

by Vincent Massol

Hi devs, Now that our Survey is over (see ) I'd like to propose that we settle on the following 2 themes for XWiki 4.x: * Theme 1: Ease of use * Theme 2: Quality This means that when we define roadmaps and more generally when each of us do development tasks, we should try to focus on doing things that are about "ease of use" first and barring that about "quality". These themes are quite general but they should be understood as improving what we already have vs developing brand new features. Of course it doesn't mean we shouldn't accept any brand new feature but more that, whenever we can, we should go in the direction of the themes. WDYT? If we agree I''ll add those themes to our Roadmap page at http://enterprise.xwiki.org/xwiki/bin/view/Main/Roadmap Thanks -Vincent
