Hello, I am working on creating blog entries using xwiki. I was wondering if it would be possible to create a template for the blog entries so that they will be more structured? Thank you for your time and help! Hande Aksac

[xwiki-devs] [VOTE] Deprecation strategy
by Vincent Massol 30 Jan '09

30 Jan '09

We need a deprecation strategy, i.e. decide for how long we keep @deprecated methods/classes. I propose to keep them for 2 full releases after the current version is released as final. For example if a method is deprecated in, say Core 1.3M2 then the method will be removed in 1.6M1. Of course any major new release can deprecate anything so a XWiki 2.0 is expected to break backward compatibility. So for methods deprecated in 1.0 we can remove them in 1.3M1, M2, etc. WDYT? If ok then I'll add this to our dev practice guide too. Note that for this to be easy anyone deprecating methods should add the information of when it was deprecated. For example: /** * @param time the time in milliseconds * @return the time delta in milliseconds between the current date and the time passed * as parameter * @deprecated replaced by {@link com.xpn.xwiki.api.Util#getTimeDelta(long)} since 1.3M2 */ public int XWiki.getTimeDelta(long time) { return this.util.getTimeDelta(time); } Here's my +1 Thanks -Vincent

LANG property in startup script in standalone version
by Vincent Massol 10 Jul '08

10 Jul '08

Hi, Does anyone know why we have the following LANG property defined in our startup scripts: #!/bin/sh export LANG=fr_FR.ISO8859-1 JETTY_HOME=. JETTY_PORT=8080 JAVA_OPTS=-Xmx300m java $JAVA_OPTS -Dfile.encoding=iso-8859-1 -Djetty.port=$JETTY_PORT - Djetty.home=$JETTY_HOME -jar $JETTY_HOME/start.jar I think this is bad as it's french and I don't think we should set it for the user. That said, if it's there its probably because it was required in the past, hence my question here. To summarize: anyone sees any issue if I remove that "export LANG" line? Thanks -Vincent

Hello, I have managed to authenticate users with the Active directory through LDAP. However, all the users i login were shown the error message "You are not allowed to view this document or perform this action." when i am at http://localhost:8080/xwiki/bin/view/Main/WebHome.

Attaching an image from another document?
by Vincent Massol 22 May '08

22 May '08

Hi, I'd like to attach an image to the current document but the image is attached to another document. I couldn't find the answer in the FAQ. It would be great if the {image:} radeox macro allowed for this. Right now the only solution I'v found (which is a bit ugly) is to use an HTML <img> tag as in: <img src="/xwiki/bin/download/XWiki/Toolbar/image.gif" /> Any other solution I would have missed?

[xwiki-devs] [proposal] JS and CSS improvements
by Ludovic Dubost 13 Mar '08

13 Mar '08

Currently the albatross skin loads around 10 js and 10 css, which is quite a lot. We can improve loading time by: - compression and cache (raffaello will provide Apache configs specific to XWiki to help for that) - merging and optimizations of css/js (I've published http://www.xwiki.org/xwiki/bin/view/Code/MergeCSS to help on that) - removing unused css/js (now we need to find which one are unused) - conditional loading of css and js. This last improvement can help us a lot since some of the css/js are not even used in view mode, or are only used by a specific panel. For this my proposal is to add a feature to the core to allow conditional loading of CSS and JS files. The current macros in the header would instead of putting CSS and JS add a placeholder for additional CSS and JS. Then everywhere where we need these CSS/JS (in a panel, in a wiki page, in a template) we would call a macro #includecss or #includejs This macro would add in the context the CSS and JS to add. At the end of the template rendering the placeholder would be replaced by the added CSS and JS. The page would be served. This would allow to manage the way CSS and JS are added. WDYT ?

[xwiki-devs] Is templates directory required any more?
by Sachin Mittal 08 Mar '08

08 Mar '08

Hi, I see that under xwiki webapp there is a template directory, that contains vm files. Same filenames are included in respective skins directory also. So based on my understanding of how velocity files are called and invoked upon user action, the vm files under templates directory play no role. Also in some previous discussion it was mentioned that they were redundant and there was a plan to separate common set of vm files into single directory. So I have two questions: 1. Can I delete the templates directory from my deployment. 2. If these files under this are no more required then what about deleting them from svn istelf. If have I have missed something and these files are required then please let me know in what case would these be required.

[xwiki-devs] MetadataLuceneTutorial on xwiki.org - Where should it go?
by Vincent Massol 05 Mar '08

05 Mar '08

Hi everyone and Jean-Vivien, Jean-Vivien has done a lot of good work adding a tutorial on xwiki.org. See http://platform.xwiki.org/xwiki/bin/view/DevGuide/MetadataLuceneTutorial However I'm wondering where we should put it. Here's my current thinking: * This tutorial reflects Jean-Vivien's point of view only since it's never been discussed AFAIK and there's no general agreement about its content with the rest of the xwiki developers. As such I don't think it can be located in at the same level as the other tutorials which have been "endorsed" by the xwiki community. I see 2 solutions: 1) We move it to the draft area and Jean-Vivien submits it for review to the xwiki dev community. If the community agrees this is the right way to implement it we put it with the other tutorials/ 2) We move it to a contribution area that clearly marks the document as a contributor's view and not as endorsed by the xwiki development community. We don't have such a place today so we'll need to create it. We could create it as a subpage of the Tutorial page in the DevGuide or we could move it to the code zone to the code snippet space since what Jean-Vivien has done is basically provide code snippets to extend xwiki. It's a little bit more than a code snippet since it's also a tutorial so I'm not sure the code zone is the best place for it. WDYT? Jean-Vivien, some quick comments/questions on the content: * Jens Karmer was the original author of the Lucene plugin. Since then it's been worked on by numerous people. * You shouldn't put ":" in titles * The tutorial is missing a section at the beginning to explain what the tutorial is about * I haven't read the tutorial yet but if what you've done is useful why not consider improving xwiki's core to support what you need? For example it seems to me you're asking for a way to add custom metadata to the lucene plugin. This could easily be added as part of the lucene plugin API. Thanks -Vincent

[xwiki-devs] Profiling: Why do attachments require so much memory
by Sergiu Dumitriu 04 Mar '08

04 Mar '08

Hi devs, Last night I checked what happens when uploading a file, and why does that action require huge amounts of memory. So, whenever uploading a file, there are several places where the file content is loaded into memory: - as an XWikiAttachment as byte[] ~= filesize - as an XWikiAttachmentArchive as Base64 encoded string ~= 2*4*filesize - as hibernate tokens that are sent to the database, clones of the XWikiAttachment and XWikiAttachmentArchive data ~= 9*filesize - as Cached attachments and attachment archive, clones of the same 2 objects ~= 9*filesize Total: ~27*filesize bytes in memory. So, out of a 10M file, we get at least 270M of needed memory. Worse, if this is not the first version of the attachment, then the complete attachment history is loaded in memory, so add another 24*versionsize*versions of memory needed during upload. After the upload is done, most of these are cleared, only the cached objects will remain in memory. However, a problem still remains with the cache. It is a LRU cache with a fixed capacity, so even if the memory is full, the cached attachments will not be released. Things we can improve: - Make the cache use References. This will allow cached attachments to be removed from memory when there's a need for more memory - Do a better attachment archive system. I'm not sure it is a good idea to have diff-based versioning of attachments. In theory, it saves space when versions are much alike, but it does not really work in practice because it does a line-diff, and a base64 encoded string does not have newlines. What's more, the space gain would be efficient when there are many versions, as one version alone takes 4 times more space than a binary dump of the content. Suppose we switch to a "one version per table row" for attachment history, with direct binary dump, then the memory needed for uploading would be 6*filesize, which is much less. -- Sergiu Dumitriu http://purl.org/net/sergiu/
