Re: [xwiki-users] Java Heap Space, Out of memory exception
An alternative is to export the pages in chunks. Install the ImportExport application, which allows to select which pages to export, and only select a few pages at a time, keeping the size of the attachments smaller. Then, import each archive one by one. The best option, however, is to install mysql and import the sql dump.

Re: [xwiki-users] Tuning xwiki for low memory webhosting service.
Robert Munro wrote: Hi, I have been using xwiki on my hosting service for a few weeks now but i am getting permgen errors (My memory allocation is 64Mb Max permgen, 128Mb Max Heap). Quite a few of the problems seem to be happening when web bots are trolling the site. Essentially i just want to display the information on the page without the show/print bar at the top and the comment/attachment/history/info tabs at th bottom so that these links arent visible at all to the web bots, as some arent reading robots.txt. Would it be best you just make a new skin? and show the bar using a velicity template? or is there a way in the permissions or config to block the show/print bar comment/attachment/history/info for guests? regards, rob. xwiki.robmunro.net You should not make a complete new skin just for this. The best approach is to change just the menuview.vm template and upload it as an attachment to the XWiki.DefaultSkin document (or the skin you have configured in your wiki). The template is pretty easy to understand IMHO, you need to find the right lines and wrap them with #if(!$isGuest) ... #end About the memory problems: - you will get out of heap memory if you use many attachments. This is buggy and wrongly designed, it should be fixed in the future. - permgen errors should not happen. What container are you using? Tomcat, by any chance? There is a bug in some containers, triggered when reloading the webapp without restarting the server. The jars are reloaded, but some of the old classes are not garbage collected. -- Sergiu Dumitriu http://purl.org/net/sergiu/ ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] Subcategories in BulletinBoard application
Hi Jorg, As of today you cannot create subcategories in the BulletinBoard application. I coded the application as a proof of concept a couple months ago and didn't have the time to come back to it since. If you feel like it (that it, is you're ready to dig into XWiki's API, class object model and velocity scripting) you can give a look at the code beneath the application's pages and try and do it yourself (this suggestion will only work if you're a coder / developer).

[xwiki-users] Default XAR merge on import
According to the installation/upgrade guide, You may want to upgrade to a newer version of the Default Wiki XAR in order to benefit from the latest changes. As mentioned above in the Installing the Default Wiki XAR section you should be very careful and when doing the import make sure you selectively decide what pages you wish to import. Is there any particularly good recommended way of doing this efficiently? [...] I would be interested in some pointers here, too. Currently for every upgrade most of the time I am busy with comparing the exported and unpacked *.xar of my wiki with the differences between the xwiki-enterprise-*.war from the corresponding releases, and update the *.xml files manually. When I reimport the changes files again in the running xwiki I always have the fear of overwriting some important local modifications, or forgot to add important updates from the release. I guess there must be better ways to do it, and maybe someone already knows one ;) I personally don't need any pretty xwiki app to do this, if I can accomplish it in my shell, it'd be fine. And barring comments, I'll try to work this up on my own. I just wondered if one day I get to the point where I could at least write an importer plugin, which accepts the pristine *.xar from the current and new release, and then updates all pages, which still have the content from the old release with the content of the corresponding page in the new release. (Well, just updating the content would not help for the Panels, which are actually the most heavily customized things in the wiki here). Though I am not there yet, partially because still have to learn the XWiki API, partially because the updates somehow went through without it.

I guess there must be better ways to do it, and maybe someone already knows one ;) Right now there are only 2 best practices: * first you should try to avoid making modification to pages bundled with the default XAR that you'd like reimport in future versions. For example if you need to change the WebSearch page you can create your own WebSearch page in your own space for example or copy it to a different name. * you could also maintain a list of default XAR pages that you have modified so that you don't overwrite them when importing a new XAR. Last there's a list of pages that you should not reimport (they are mentioned in the installation guide). Of course none of this is perfect and it won't be perfectly till we have finished the new application manager: http://dev.xwiki.org/xwiki/bin/view/Design/ApplicationManager The work for it is going to start in XE 1.8 but since it's a complex thing it'll probably be fully operational only around 1.9 or maybe even 1.10.

You could probably even reuse the diff API to compare the versions. That said what you describe is very similar to the application manager idea we have: http://dev.xwiki.org/xwiki/bin/view/Design/ApplicationManager You are very welcome to help us design it. Thomas Mortagne and Jean- Vincent Drean are the ones who have planned looking into this during the XE 1.8 timeframe.

[xwiki-users] Removing the Register Link
I'm using XWiki Enterprise version 1.6.1.13621. I was following the instructions in the FAQ to forbid registration ( http://www.xwiki.org/xwiki/bin/view/FAQ/HowCanIForbidRegistration, which seems to be out-of-date for my version BTW) and noticed some strange behavior. I don't want anyone to self-register so I denied access in the Register column of the Rights admin page for all groups. I logged out and noticed the register link was still on the page. I tried registering a fake user and it worked. After playing around for a while I figured out that I had to actually grant Register access for the XWikiAdminGroup group to get the Register link to disappear. If I deny Register access or just leave it blank for the XWikiAdminGroup group the Register link is present and works. This is backwards to me. Without looking at the code it seems like a logical error somewhere. Could someone tell me whether I'm understanding this process correctly or not? -- Nick Watts blog: thewonggei.wordpress.com ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
