[xwiki-users] Futex errors
by Aaron Hardy at AC 20 Feb '15

20 Feb '15

Trying to track down the source of some persistent performance issues under load with 6.2 RC 1 (haven't had time to upgrade to 6.2 final yet). I'm maxing out at about 30 or so users before dying on a system with 4GB of RAM. The java interpreter is getting pegged to 100% of the CPU, and about 70% of the calls in the stack trace are futex lock errors. A good chunk of the remainder are gettimeofday calls. Potentially useful info (sorry for formatting): % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 72.75 5361.592109 45075 118947 14045 futex 12.28 905.064191 466 1943354 gettimeofday 4.83 356.110745 3709487 96 45 restart_syscall 2.88 212.173358 836 253729 clock_gettime 2.71 199.867690 8802 22706 recvfrom 2.10 154.843342 37841 4092 poll 1.14 84.282371 580 145307 130153 stat Any ideas? thanks, aaron

[xwiki-users] Diagram Application
by Hamster 28 Oct '14

28 Oct '14

I am testing XWiki 5.0.2 (standalone ZIP version) to take a look at some extensions which don't work with our current XWiki 4.0. One of these extensions is the Diagram Appication <http://extensions.xwiki.org/xwiki/bin/view/Extension/Diagram+Application> I have a couple of questions: 1) In the Diagram Applications, there are nice graphs (computers, network, etc). I can see those graphics when I am in the edit mode, but as soon as I "Save & View", those graphics are not displayed anymore! How can I get these graphics to show? 2) I would like to include a diagram in another page, but if I use the "Include" macro, I only get the "XML-text" (and not the actual diagram). How can I "include" a diagram into a page? Thanks in advance! -- View this message in context: http://xwiki.475771.n2.nabble.com/Diagram-Application-tp7585510.html Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Flamingo skin in action
by Valdis Vītoliņš 02 Oct '14

02 Oct '14

Thanks to all XWiki'ers for Flamingo skin! You can look at it in action at http://ante.lv/ and it is much more mobile-friendly. I used {{container}} macro for 1/2 column layout for home page. I still had to do some adjustments in XWiki.StyleSheetExtension object to hide some unnecessary items on screen for anonymous users: #if(!$xcontext.userReference) .xwikipanelcontents, #rightPanels { display:none; } #end And had some weird issues with language selector http://jira.xwiki.org/browse/XE-1427 Valdis

[xwiki-users] Rest API -- XML and Xwiki syntax interference
by rol 02 Oct '14

02 Oct '14

Hello, I want to do a bulk import of some 80 wiki pages (i.e. files) in xwiki 2.1 syntax to an xwiki instance. However, in the input there is some xml within {{code}}...{{/code}} sections which creates trouble. The following xml markup: {{code}} <property as="xs:anyURI" name="oxf.fr.detail.send.success.uri.*.*" value="http://localhost:8080/site/mycases/form/confirmdispatcher"/> {{/code}} causes the parser to derail. To prevent this from happening, I must substitute the '<' and '>' with < and > respectively. However, when pasting exactly the same code directly into the xwiki-editor in source mode the content is parsed correctly. Is there any better way to solve this problem than to pre-process all xwiki-2.1 files and perform the necessary substitutions within code sections such as above? BTW I used a scriptified version of the following command for the operation: curl -u Admin:admin -X PUT --data-binary "@input.xml" -H "Content-type: application/xml" -H "Accept: application/xml" http://wiki.motrice.org/xwiki/rest/wikis/xwiki/spaces/Motrice/pages/NewPage Best regards, Roland -- View this message in context: http://xwiki.475771.n2.nabble.com/Rest-API-XML-and-Xwiki-syntax-interferenc… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Problems creating new wikis - PostgreSQL?
by Bryn Jeffries 01 Oct '14

01 Oct '14

I've tried creating a new wiki "Other Wiki" under my XWiki 6.1 system, using the "Add Wiki" feature. Once I'd entered the details of the wiki and the users I clicked "Create Wiki" and got the following error: Wiki "otherwiki" creation failed: org.xwiki.wiki.manager.WikiManagerException: Failed to create database for wiki "otherwiki". FWIW I'm running XWiki on a PostgreSQL database. Could this be part of the problem?

[xwiki-users] [Discussion] What trees would you like to see in the XWiki garden?
by Marius Dumitru Florea 30 Sep '14

30 Sep '14

Hi guys, There are a couple of places in XWiki where we use trees to display structured / hierarchical data. Are trees a good solution for data visualization in those cases? Can those trees be improved? Are there other places in XWiki where you would like to see a tree? Let me review some of the trees we currently have: 1. Document Index Tree wiki > space > page > [attachments | page] This tree is also used in the WYSIWYG editor when you create a link to a wiki page or to an attachment. It shows the spaces on the first level and then under each space the parent-child hierarchy of documents from that space. If a document has attachments then a special child node is added. The tree can also display wikis on the first level and then spaces on the second. So it mixes two hierarchies: wiki > space > page > attachment and parent > child. This can be confusing. For instance Blog.WebHome has Main.WebHome as parent, but you don't see Blog.WebHome under the Main.WebHome node in the tree because it is in a different space. 2. XAR Import space > page This is a very simple tree with only two levels. I don't have any problem with it. Would be cool if it would show more information, like attachments or objects, but it's a bit more complex to get this kind of data from the XAR without reading the documents first. 3. Dynamic Hierarchy Macro ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Dynamic+Hierarchy+Macro ) parent page > child page Unlike the Document Index Tree, this tree uses only the parent-child hierarchy. You don't see the spaces but at least you get the full parent-child hierarchy. This time Blog.WebHome is a child of the Main.WebHome node. I'm not sure it's better than the Document Index Tree, at least not on the default XWiki documents, maybe because the document titles and the way we set the parent in the default distribution is not very consistent. ---------- WDYT about these trees? As a developer, I would love to see a full XWiki Entity Tree: wiki > space > page > [translations | attachments | objects | classProperties] > object > objectProperties As in http://imgur.com/q0br8xT . As a user, I don't know. You tell me :) Thanks, Marius

[xwiki-users] Admin rights after migration
by Moens Patrick 30 Sep '14

30 Sep '14

Hello , I've a strange bug since Friday. I've installed a fresh xwiki 6.1 on tomcat/oracle 2 weeks ago and imported exported data from a old xwiki 2.3 (but data have been migrated to xwiki 6.1 before export). Everything was ok until Friday. Now every users have admin rights but they are not in the admin group. They have access to all spaces,/docs. If anyone have an idea. I've check rights, and nothing change between pre production server and problematic prod :/ PAtrick

[xwiki-users] from preview mode to view mode
by Roland Hedayat 30 Sep '14

30 Sep '14

Hello, In a fresh installation of xwiki 6.2, I create a space X and then a document Y in that space. However, I cannot see the document, although when clicking the 'Information'-button for the space X, I find the document Y in a subspace 'preview'. I find no way to promote the document so that it becomes directly available in X. Regards, Roland
