[xwiki-devs] Statistics for links to external pages in Xwiki
by felixixix 19 Jun '14

19 Jun '14

To implement an "most visited links" box, I need information about what external pages are visited the most from XWiki-pages. First idea (lacking knowledge on how to implement it): - change link parser to tranformer links like "http://www.externalpage.com" to "http://www.mypage.com/proxypage.php?destination=http://www.externalpage.com" - implement proxypage at "http://www.mypage.com/proxypage.php" to count destination and Redirect I am thankful for any suggestions...

[xwiki-devs] undeleting a document programmatically?
by Paul Libbrecht 18 Jun '14

18 Jun '14

Dear XWiki experts, I've been trying to undelete documents programmatically and I must say I failed thus far. I need to do this so as to implement the undeletion of 450 documents. Given the full name of the document, which currently shows when /view/-ed, that it has been deleted and offers me to restore or really delete, I am calling: xwiki.getDeletedDocuments(fullName, "en"); however, thus far, the result of this call has been an array of size zero. I would have expected to call the undelete method on the last of these DeletedDocuments. Is this not the right way to act? thanks in advance. Paul

[xwiki-devs] [Brainstorming] "A method for giving credit to organizations that contribute code to Open Source"
by vincent＠massol.net 17 Jun '14

17 Jun '14

Hi devs/contributors/everyone, This is an interesting article forwarded to me by Ludovic: http://buytaert.net/a-method-for-giving-credit-to-organizations-that-contri… I’ve been thinking a bit about it and the simplest solution I could think of (if we ever wanted to do something in this direction) would be: * Add a new custom field in JIRA called “Sponsored By”. Since all our commits have associated JIRAs this should work fine to recognize everyone. * Then we can easily query JIRA on a wiki page to provide visibility about companies and individuals sponsoring the development of XWiki. * For example we could have a new page available in the Contribute menu of the top level horizontal menu called Sponsors which would: - list all committers: link to the Hall of Fame page (http://dev.xwiki.org/xwiki/bin/view/Community/HallOfFame) - list all Supporters: link to http://www.xwiki.org/xwiki/bin/view/Main/Supporters - list all sponsors: query JIRA and list all sponsors including # of issues sponsored with ability to clean on each sponsor and go in JIRA itself to see the details WDYT? Would you be interested in this? Thanks -Vincent

[xwiki-devs] [Proposal] Link the color theme application to the skin
by Guillaume "Louis-Marie" Delhumeau 17 Jun '14

17 Jun '14

Hi devs. I am implementing the Color Theme Editor for Flamingo! And this is a preview: http://design.xwiki.org/xwiki/bin/download/Proposal/ColorThemeforFlamingo/f… Since the current color theme application is strongly linked to Colibri, and the new application will be strongly linked to Flamingo, I propose the following: 1/ move xwiki-platform-colorthemes in xwiki-platform-colibri and state that this application is only compatible with colibri-based skin. 2/ create the new application in xwiki-platform-flamingo 3/ the new color theme application will actually propose more than colors (fonts, less code, etc...), so I propose to call it xwiki-platform-flamingo-themes. 4/ in the administration, we have a page that propose which color theme we want to use. Since the new application will not be compatible with the old one, I propose to add an extension point (such as what we have to configure search suggest sources) in order to propose the themes corresponding to the selected skin (ie: xobjects of ColorThemes.ColorThemeClass for colibri and skins based on colibri, and xobjects of FlamingoThemeCode.ThemeClass for flamingo). 5/ modify SkinAction that currenlty executes velocity code on a skin file if the mime type is CSS or JS, to also execute velocity on files suffixed by .less.vm, because I need it for my application. To see what it looks like, please look at https://github.com/gdelhumeau/xwiki-platform/commit/49aca5733f4a820f3d1327c… . The alternative is to create a new action which is too much IMO. 6/ when colibri will be deprecated on removed from XE, we will do the same for the old color theme application. WDYT? Thanks, Guillaume

[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
