[xwiki-users] Bug in Filesystem Attachment Porter
by Paul Harris 01 Jul '11

01 Jul '11

Hi again, I tried to transfer all my attachments to the filesystem with the script: http://extensions.xwiki.org/xwiki/bin/view/Extension/Filesystem+Attachment+… which IS a core extension (at least developed by the dev team). I'm using jetty, and it fails with this error: /var/cache/jetty/tmp/work/storage/xwiki/XWiki/XWikiSyntax/~this/attachments/img.png/img.png~tmp (Too many open files) I found that jetty had many many open files - it had created and left open the handle on hundreds of files in /var/cache/jetty/data/upload__* Was this tested against a full sized wiki? My wiki isn't very big at all yet, maybe a few dozen pages at the most. Does this happen on a tomcat server? Maybe noone checked it on jetty? Seems like leaving the handle open isn't a scalable solution ... I'm looking at the code for the script, I'd like to fix it somehow... Can someone please give me a tip? cheers Paul

[xwiki-users] Empty Trash Can extension doesn't work
by Paul Harris 30 Jun '11

30 Jun '11

Hi, I couldn't even backup my sql database anymore because there are large pages (with attachments) in the recycle bin -- at least thats what I gathered from the mysqldump error message: mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table `xwikirecyclebin` at row: 45 I will have to adjust the max package size (again), but I want to move to file-system attachments. So, I thought I'd try and empty the recycle bin... I found the "Deleted Documents" list in the Document Index, but I have over 5 pages of them. Do I seriously have to click delete and Yes on every single one of these individually? I found this extension: http://extensions.xwiki.org/xwiki/bin/view/Extension/Empty+Trash+Bin I installed the Groovy Console and copy-pasted the code into the box, and clicked Execute... and nothing happened. I looked at the code, and executed the sql command directly in mysql: select distinct ddoc.fullName from XWikiDeletedDocument as ddoc where not exists (from XWikiDocument as doc where doc.fullName=ddoc.fullName); But it doesn't work - invalid SQL. I adjusted it to: select distinct ddoc.fullName from XWikiDeletedDocument as ddoc where not exists (select doc.fullName from XWikiDocument as doc where doc.fullName=ddoc.fullName); but it says XWikiDeletedDocument doesn't exist anymore. So, how am I supposed to delete things from the recycle bin? The only thing useful I can find is this: http://markmail.org/message/6yxwwczjk7pwowbd Which seems to suggest I do: delete from xwikirecyclebin; But, will that stuff something up? The extension is out of date, so I can only assume that this advice might be too. cheers Paul

[xwiki-users] Memory issues
by Paul Harris 30 Jun '11

30 Jun '11

Hi, I've upgraded from XE2.6 to XE3.1, and found I couldn't export to PDF anymore - not enough memory. So I increased the amount of memory for jetty to 720mb (it was already 512). I found after working with the wiki for maybe 30 minutes, something else would run out of memory. So i have to restart jetty every 20 minutes sometimes. I can only tell I have a problem when I start getting "can't parse vm whatever code" messages in the webbrowser. I'm not sure if this is a memory leak issue... I found that repeatedly clicking Export (in export-PDF) would increase the resident memory (in linux) all the way up from maybe 130mb to 1008mb (the virtual memory size) in jumps of over 50mb. Further clicking on the Export would would not increase the resident size, so I'm not sure what is going on there... is this a sign of a massive problem? cheers Paul

[xwiki-users] Display Objects help
by Ashtar Communications 29 Jun '11

29 Jun '11

Hi, At the outset - I admit to being a complete and total newbie at this. Apologize for asking what are probably dumb questions - and likely to be lots more than one. Any help people would be willing to give me would be much appreciated. I have been through all the tutorials, the API JavaDoc, and as many examples of code as I could find, but I still can't seem to find anything that looks directly applicable or works when I try to adapt it. What I'm ultimately trying to do seems pretty straightforward. I would like to have a set of pages which each contain structured data that can be modified, added, or deleted one object at a time, and which display in reverse chronological order. I would like each of those objects to be displayed with specific HTML formatting. Eventually, I will also need to be able to interact with those objects using the REST API. My current understanding of the process I need to use to get started is this: 1) Create a new Class (We'll call it "Entry") with specific properties 2) Create the Class Sheet and Template. The Template includes a link to the Class Sheet for displaying instances of the class. 3) Edit the Class Sheet to get the attached objects to display properly 4) Create a new page from the Template, add several instances of the class to it - they should then display on the new page. First two steps are easy - but the first place that I am hung up is figuring out how to get the Class Sheet to display multiple objects of the same class attached to the same page. I have a page with 3 objects of the Entry class attached (with different info in the properties). Ultimately the info and formatting will need to be more complex, but I can't even get the basics to work - this is what I have tried so far: ****START CODE**** #foreach($entry in $doc.getObjects("XWiki.EntryClass")) #foreach($prop in $entry.properties) : $doc.display($prop.getName()) #end #end ****END CODE*** The problem is that this code displays the info for the first object three times, instead of the unique properties for each class. The fact that it displays three times seems to indicate that the loop is correctly going through each object in the document - but it is obviously not incrementing the properties to the next $entry. Sure it's a simple syntax error, but don't know what it is. I also can't tell from the JavaDoc enough about how to use .display() or the properties of a vector to know how to do basic things like display the number of objects or the name of each one. Can't figure out how to interact with objects very well, basically. Side question - Should I be using one object per page and then including pages instead of having multiple objects on one page? I have worked my way through the TOC demo, and it seems that each TOC entry is saved on a separate page - and the livetable macro is then used on the "display" page to populate the table with all the entries. Thank you in advance, Aaron

[xwiki-users] Template attachments not loaded
by Ramon Gomes Brandão 28 Jun '11

28 Jun '11

Hi, I've created a page template that has some images on it (like different logos according to the document). On the template, I've upload the image and inserted it on wysiwyg option. I used, then, this page on my template provider. When I create a new page from this template, the image seems to be not copied from the template to the new page, and the image is not loaded. Any way to turn around on this? I'm using XE 3.1-M2. Regards, -- * * * * *Ramon Gomes Brandão* *//*

[xwiki-users] Admin screen errors (TemplateParseException...) on upgrade to 3.1
by Tim Jones 28 Jun '11

I have just carefully upgraded a wiki from 2.6 to 3.1 At first glance It seemed to have gone fine, but I noticed velocity errors on the new-style Admin page (XWiki.XWikiPreferences): ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ...

[xwiki-users] Component registration process
by Wouter 27 Jun '11

27 Jun '11

Hello, I am trying to replicate the first example in the tutorial[ http://rendering.xwiki.org/xwiki/bin/view/Main/GettingStarted] using Maven. It worked great at first, but when I try to build a shaded JAR using the maven-shade-plugin, I keep getting a nasty exception: org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [org.xwiki.rendering.converter.Converter] hint = [default]] It seems that some descriptor should have registered itself, but it does not always do that, depending on the project setup. My question: is there a way to poke whichever class has to register itself? If not, can you point me to a place where I can learn more about the registration process? All the best, Wouter
