[xwiki-devs] Macro execution at the page save time.
by Karel Gardas 13 Jun '14

13 Jun '14

Hello, I'm working on semantic extension for XWiki[1][2] and currently on performance tunning to be ready for scaling up. The problem with current implementation is that it always modifies semantics DB on all page views. E.g. when I do have a page with {{semProp value="http://purl.org/dc/elements/1.1/title::The Hobbit"/}} to define property 'title' to value 'The Hobbit', this macro basically saves this knowledge to the DB everytime the page is viewed which is obvious performance killer. Of course there is a possibility to optimize this call to first check if the property is already defined and if not, do nothing, but it's still not the best. What I think I'd like to do is to kind of check if the pages is saved or viewed and based on this semProp will do its job (during page save) or will do nothing (during page view). Now, my question is if something like that is possible since I've not found any hints about it so far. Thanks!

[xwiki-devs] Out of memory errors (scalability of xwiki).
by Karel Gardas 13 Jun '14

13 Jun '14

Folks, I'm testing kind of scalability of XWiki by simple benchmark which creates N pages in a loop (one page at a time, it's not parallel run!) and then when this loop finishes, it again in another loop gets all the pages from the server (again serially, one page at the time). For page creation we're using REST API, for getting the pages we're using common browseable URL (/xwiki/bin/view/...). Now the problem is that if I try to attempt creation of 100k pages, then I hit Java's out of memory errors and server is unresponsive from that time. I've tested this on: - xwiki-jetty-hsql-6.0.0 - xwiki-jetty-hsql-6.0.1 - xwiki-tomcat7-pgsql -- debian xwiki packages running on top of debian 7.5 Of course I know the way how to increase Java's memory space/heap space. The problem is that this will not help here. Simply if I do so and then create 100 millions of pages on one run I will still get to the same issue just it'll take a lot longer. I've googled a bit for memoryleaks issues on Java and found an interesting recommendation to use parallel GC. So I've changed start_xwiki.sh to include -XX:+UseParallelGC in XWIKI_OPTS Anyway, the situation is still looking suspiciously. I've connected JConsole to the xwiki java process and overall view looks: https://app.box.com/s/udndu96pl2fvuz3igvor this is whole run overview, but perhaps even more clear is it on last 2 hours view which is here: https://app.box.com/s/deuix33fzejra4uur941 Sidenote this all is from debugging xwiki-jetty-hsql-6.0.1 distro. Now, what worries me a lot is this bottom cap which is growing. You can see that clearly in Heap Memory Usage from 15:15. In CPU usage you can also see that around the same time the CPU consumption went up from ~15% to ~45% When I switch to Memory Tab in JConsole and click several times on "Perform GC" button, the bottom cap is still there and I cannot get lower in memory usage. With this going on I can also see server failing after some time on OOM error. Any help with this is highly appreciated here. Thanks! Karel

[xwiki-devs] Registered Listeners (observation module)
by Danilo Amaral de Oliveira 11 Jun '14

Hello Developers, How are you? Last weeks we have added some listeners to our XWiki platform. I am losing the control in what listeners are registered and working. Is there a way in the observation Module to check what listeners are registered and working? Thanks Danilo Grupo Energisa Danilo Oliveira Analista Suporte Aplicacao TI - DPTO CORP. DE INFRAESTR.

[xwiki-devs] [proposal] Install Realtime WikiText editor extension on myxwiki.org
by Caleb James DeLisle 11 Jun '14

11 Jun '14

Hi, I'd like to propose installing the Realtime WikiText extension on myxwiki.org. It has already been installed on webviewers.org and in XWiki SAS internal wiki. I would like to broaden the scope to myxwiki.org and then xwiki.org. Myxwiki.org is a special scenario because it contains many subwikis, some of which have fairly radical custom skins. However after some thought I decided we should install the extension globally anyway because it will allow us to gather the widest range of feedback about it's behavior. I propose to write a document explaining how it works, where to report issues and how to disable it, install the extensions globally on myxwiki.org, then place a banner on myxwiki.org for 1 week which invites administrators to the document. WDYT? Caleb

[xwiki-devs] onEvent does not save the document
by walid yaich 10 Jun '14

10 Jun '14

Hi community, I have a listener on DocumentUpdateEvent List<Event> getEvents() { return Arrays.asList(new DocumentUpdateEvent()) } void onEvent(Event event, Object source, Object data) { println "onEvent start !" def obj = source.getObject("Revision.RevisionClass") source.setComment('this is listener comment') println obj.getName() obj.set("approvedRev", '1.1', data) println "onEvent end" } I'm sure onEvent is executed but the document is not saved. The same problem with DocumentUpdatedEvent when i added saveDocument, i got stackoverflow. I tried on XWIKI 4.4 and 5.4.5, with no success Thanks in advance :)
