[xwiki-users] WARN xwiki.MyPersistentLoginManager - Login cookie validation hash mismatch!

by Nevzat Guler

Hello xwiki users, I just installed xwiki on windows server. I unpacked the stand alone version Stable: xwiki-enterprise-jetty-hsqldb-2.6.zip into a directory called XWikiHome and setup MySQL data base, created a new user. When I am in the server itself, I can login. But when I try to login from another computer I cannot login and the xwiki creates a message: WARN xwiki.MyPersistentLoginManager - Login cookie validation hash mismatch! Cookies have been tampered with I have seen a few other emails regarding the same issue. But I don't see a solution. One suggestion was to change cookie version to cookie.setVersion(1); but I am not sure where this change needs to be made? My XWikiHome folder contains the following folders and files: XWikiHome: database (folder) jetty (folder) META-INF (folder) webapps (folder) start_xwiki start_xwiki start_xwiki_debug start_xwiki_debug stop_xwiki stop_xwiki xwiki Within the folders, I don't see any configuration file or a file like a "..LoginManager..". Did I not install this correctly? But I can actually open the pages when I am in the server from internet explorer. But from another computer, I get the login page but cannot login. As a side note, I have tried version 2.5 last week and I did not have this problem. Then I wanted to change the location of the xwiki, so I deleted that directory and reinstalled the 2.6 version into another drive. I appreciate your suggestions. Thanks, - Nevzat

[xwiki-users] Section editing - overwriting wrong section

by Piotr Dziubecki

Hi, lately a user reported to me another issue regarding sections. Scenario, there are two users and document like that: == section 1 == sect content == section 2 == sect content == section 3 == sect content 1. UserA opens section 2 to edit 2. UserB opens whole document to edit ( no other way but with force editing ) 3. UserB adds section 1.5 in the way it is: == section 1 == sect content == section 1.5 == sect content == section 2 == sect content == section 3 == sect content 4. UserB saves document. 5. UserA changes content of the section 2 and saves document. The result is that userA saves overwrites section 'section 1.5' instead of 'section 2'. I can see that you're indexing section with numbers and add this as a parameter to edit link and that is probably the reason of shifting the section change but I've just checked the Media wiki sandbox and the same scenario causes no errors - they are also adding the 'section' parameter but somehow an extra identification is performed as well.. Is there any chance to get that working right ? maybe some configuration switch.. Thanks, Piotr

[xwiki-users] Trying to find a wiki software

by Eric Tse

Hey guys, just subscribed to this list. I'm currently stuck between two softwares: XWiki and Foswiki. What I'm looking for is: Speed/Performance Access control (Guests can only read and not modify, certain users can modify) Good theming/Easy theming. An overall good wiki with user-friendly UI. Foswiki is flatfile and xwiki is SQL based. I hear that SQL is generally better, is that the case? Foswiki seems to be pretty fast even if it is flatfile. Thanks :) - Eric

[xwiki-users] Solving performance problems

by Ivan Levashew

I have recently started to fill my wiki with lots of content. Currently I have 4772 XWiki documents and 2260 XWiki objects. Not so much I think, but it looks like I'm reaching a limit. This is first time I have looked into SQL internals of XWiki. Goddamn! There were no indices except primary ones! OK, I have lowered load time from 15sec to 9sec having created indices (e. g. XWD_FULLNAME in xwikidocs) Still too much. Maybe I could improve it any further, but some queries are maid the way I don't know obvious way to make index for them. For instance, I can see "where hidden <> 1 or hidden is null" in queries. It would be nice to see "where hidden = 0" instead (and null being not allowed) Xen:~ OCTAGRAM$ time GET http://blog.toom.su/ [...snip...] </div></div></body> </html> real 0m8.395s user 0m0.158s sys 0m0.052s Xen:~ OCTAGRAM$ time GET http://pascal.toom.su/Index [...snip...] </div></div></body> </html> real 0m5.537s user 0m0.157s sys 0m0.043s Xen:~ OCTAGRAM$ time GET http://www.xwiki.org/xwiki/bin/view/Main/News [...snip...] </div></div></body> </html> real 0m1.981s user 0m0.152s sys 0m0.034s 2 second is also too much, but how do you keep response time that low? Is it just due to the fact you scatter documents across different databases or may be there was a huge improvement from 2.4M1? http://pascal.toom.su/Index is even not a dynamic page, it just has lots of wiki links. -- If you want to get to the top, you have to start at the bottom

[xwiki-users] Gift for the XWiki Community

by Maxime Sinclair

Hello XWiki Community, Christmas is coming, and I have a gift for you. I hope you will enjoy it. As you may know, recently, a Brazilia advertising agency produce fake vintage ads for Facebook, Twitter, YouTube and Skype. I thought these posters are really amazing. You will find the story here http://www.dailybloggr.com/2010/08/cool-vintage-ads-of-facebook-twitter-you… More recently, I read the book "From Airline Reservations to Sonic the Hedgehog: A History of the Software Industry" by Martin Campbell-Kelly (2003). Each chapter is illustrated by an official old ad of a software. And I was charmed by the poster of AUTOFLOW, showing the face of a woman with beautiful eyes. http://u1.ipernity.com/17/25/71/9552571.c1e1c1ef.jpg This give me an idea : to make a fake XWiki ad, copying the Autoflow one. Of course, XWiki is a so great wiki that it doesn't need advertising to spread the world. Maybe it can help... It's the result of this idea that I'm glad to give you today. I paid attention to produce this work with public domain material so I think I can publish this poster in the public domain (even if I'm far from being a license specialist). So I encourage you to print it on your t-shirt, on your mug, to modify it, to share it, to redistribute it. I've tried to preserve the message of the ad, just replacing some words, or at least to retain the spirit of the original sentences. But I'm sure you can find better arguments and it's easy to edit with Gimp. This page will show you the fake ad for XWiki in a small size but it's easier to compare with the original work : http://www.ipernity.com/doc/sinclair/9552524 The full work is available in a public google doc folder (you don't need to have an account) https://docs.google.com/leaf?id=0B2p8AuezuBCcZDc2MWY0M2EtNjBiNC00MWRmLWEzZT… - copyrights.txt describes the origins of the photo and fonts used - XWikiForChristmas.xcf is the Gimp file of the poster - XWikiForChristmas.jpg is the full resolution image (exported from Gimp) For your information, Autoflow was a software development tool that produces automatically the flowchart of a computer program. In 1965, Autoflow was the first commercial software to be sold as an independant product (not attached to a hardware device). It was a big success for ADR, its editor, with more than 10000 units sold. To conclude, I hope this encourage you, the XWiki community, to develop smart features, to maintain a high level of quality and to support kindly stupid users. Long live XWiki and merry Christmas to you and your family. Maxime Sinclair

[xwiki-users] i got an "null value at unknown namespace" error

by Tronicek

Hi, I'm testing XE 2.6 with XEM. My plugins/applications are - xwiki-application-application-manager-1.16.xar - xwiki-application-wiki-manager-1.22.xar - xwiki-enterprise-manager-application-xem-2.6.xar (corresponding .jar files are at WEB-INF\lib) Our Environment is Jboss 4.2.1 web server and Oracle 10g database. There is a problem with the Activity Stream at the homepages of the farm members. The "Activity Stream" keeps empty and there are some identical lines within the jboss console log: 15:50:59,267 ERROR [DefaultVelocityEngine] Left side ($events.size()) of '>' operation has null value at unknown namespace[line 648, column 21] After disabling the "Right column" of the Dashboard page the error does not appeare. The error does not happen at the master wiki of the farm (http://localhost/xwiki/bin/view/Main/Dashboard), only at all member wikis. Do you have a hint where to look further? Thanks, Rudi -- View this message in context: http://xwiki.475771.n2.nabble.com/i-got-an-null-value-at-unknown-namespace-… Sent from the XWiki- Users mailing list archive at Nabble.com.

[xwiki-users] Upload files on MyXwiki: tyhere are max size limits?

by Fortini (Gmail)

I'll tried to upload a number of files with these results: 1 - file type .jpg, size 2 MB --> ok 2 - file type .mp3, size 11 MB --> ko (?) 2a - when I used the button "attach" (at the bottom of the page, in the attachments folder) I received no info but no attachments had been loaded 2b - when I used the "Link" command in Edit mode I received an "error" message but the file had been correctly attached (and is still there and correctly downloadable) 3 - file type .mp3, size 70MB --> ko (+ crash?) I tried to upload a extra-large file in Edit mode. Everything appear to be all right but after 6 minutes (equivalent to 15-18MB of upload @ 0.5Mb/s) sharply the traffic on LAN was stopped but the upload popup continue to be active and "busy". No errors info at all. After 2 hours I closed the popup and correctly continue to edit the page. I saved. No attachments found. Questions. There are limits on file size? There are limits on total files amount? It's possible to state the limits on the popup (just to remember limits)? Many thanks Giuseppe Fortini

[xwiki-users] Problem with search textfield

by Werner Greßhoff

Hello, I've installed a wiki farm and observed a minor problem: in the main wiki, when I click in the standard search textfield, the text ("search...") vanishes. In my virtual wikis it doesn't. This is the tag (absolutely identical): <input class="globalsearchinput withTip" id="headerglobalsearchinput" name="text" value="search..." size="15" type="text"> The text field from the panel is working fine (everywhere). Best wishes Werner

[xwiki-users] Xwiki Enterprise 2.6 Apache2 + Tomcat6 + AJP connector + ProxyPass results in Infinite redirect loop on login page

by Mark Blokpoel

Dear all, I have recently installed Xwiki Enterprise 2.6 on our server (Ubuntu 10), deployed in Tomcat6. For this server we use two domains: domain1.example.com and domain2.example.com. By default Tomcat (and the XWiki) can be accessed via http://domain1.example.com:8080/xwiki/, but for security and easy-access we need the xwiki to be accessed from http://domain2.example.com/xwiki. This is why Tomcat is fronted by Apache2 using the AJP connector via a proxy pass which is configured in Apache sites-enabled: <VirtualHost *:80> ServerAdmin root(a)example.com DocumentRoot /var/www ServerName domain2.example.com <Proxy *> AddDefaultCharset Off Order deny,allow Allow from all </Proxy> ProxyPass /xwiki ajp://localhost:8009/xwiki/ ProxyPassReverse /xwiki ajp://localhost:8009/xwiki/ </VirtualHost> This configuration works, the xwiki can be accessed from domain1 and domain2 however there are some problems. The first thing I noticed is that the same wiki has has a different skin on each domain (no xar loaded, no user logged in). Second whereas I can access the login page athttp://domain1.example.com:8080/xwiki/bin/login/XWiki/XWikiLogin, trying to access the login page athttp://domain2.example.com/xwiki/bin/login/XWiki/XWikiLogin fails with an infinite http redirect (redirecting to the same login page, HTTP/1.1 302 Moved Temporarily). My questions are: is this type of configuration supported? If so, why is xwiki generating a redirect on the login page to the login page on domain2 and not on domain1? Thank you for the help. Best, Mark
