[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] Failed to execute the [groovy] macro while creating an app within a minute
by Peter Duever 20 Feb '15

20 Feb '15

Hello XWiki Community, while creating an App within a Minute I get groovy executing failures for each element of the form. It is possible to save and finish the process but I cannot access the editor for the content field. That means I cannot enter default entries. You can see the full failure message at the end of the mail. I googled the problem and found entries for Confluence. Maybe they can guide a way: Now I added the "-XX:ReservedCodeCacheSize=64m" option into JAVA_OPTS. (https://bobswift.atlassian.net/browse/SCRP-129) and It worked for me, I just added XX:ReservedCodeCacheSize to my setenv.sh and until now everything is ok. (https://answers.atlassian.com/questions/13535/problem-with-the-script-runne…) I am running version 5.4.5 Thank you for your time! Best regards, Peter Here is the error which is displayed when I reenter the wizard page for step 2: Failed to execute the [groovy] macro: java.lang.VerifyError: (class:

[xwiki-users] Glossary feature of xwiki
by Dai Bo 18 Feb '15

18 Feb '15

Hi, As I have failed to find the related information of this subject, I hope the email group can help me. Why Glossary feature was not implemented in xwiki? Is there any extension or alternatives? I did think Glossary is a useful feature especially for a dev team. Thanks Regards Peter

[xwiki-users] What would you like to see in the XWiki 7.x cycle?
by vincent＠massol.net 18 Feb '15

18 Feb '15

Dear XWiki users, We’re getting close to the end of the XWiki 6.x cycle (6.4 is planned for the end of December) and in January we’ll start developing the XWiki 7.x cycle (which will last the whole 2015 year), starting with XWiki 7.0. Thus it’s time for the XWiki devs to start defining the global roadmap for XWiki 7.x. As XWiki users, I’d like to know if you have some needs for XWiki 7.x. What would you be interested in seeing in XWiki 7.x? I’d like to start some proposal on the xwiki devs list (for the XWiki 7.x cycle) around end of December so it would be nice if you could shoot your suggestion ideas fast so that we can take them into account in the discussion! :) Thanks a lot for your help and I hope you’re enjoying using XWiki! -Vincent Massol XWiki Committer

Re: [xwiki-users] XWiki search/Solr support for additional filetypes
by Arnold, Garth 18 Feb '15

18 Feb '15

Hello Marius - thank you for the detailed reply. My goal is (2) - to find all documents with a .7z attachment, where those attachments include file(s) containing "foo". If I read your email correctly, Tika 1.6 (5) is root cause for my failure to search successfully for text within the files contained in a .7z attachment. I am successful with my search when using a .zip file as the attachment - so we will instruct wiki users to avoid .7z attachments.

[xwiki-users] whiteboard
by Paul Pinkerton (ACLCO) 18 Feb '15

18 Feb '15

Does anyone have experience deploying a whiteboard within a wiki page similar to https://awwapp.com/ , http://webwhiteboard.com/#/ , http://cosketch.com/ or similar? I have a need to deploy one - and using a third party service and embedding it in the page is fine, but am having trouble displaying it. This one with the code pasted below seems to work, but the app/ third party service isn't what we really want - it's a mind map service. Others seem to embed, but then don't display anything. This one seems to be one that could be hosted on our own server (??) which would actually be ideal longterm. https://code.google.com/p/online-whiteboard/ Ideally, I'd like to be able to use one that doesn't require further fees - as it sort of defeats the purpose of our own wiki structure. Anyway, any ideas or your experience here would be appreciated! We are currently running XWIKI ENTERPRISE 5.4.5, but looking at upgrading to 6.3 shortly. {{html clean="false"}} <iframe src="https://www.mindmup.com/#m:a18712bed014d6013247a842795da66744" width="800" height="600" frameBorder="0" webkitAllowFullScreen mozAllowFullscreen allowfullscreen></iframe> {{/html}} Paul Pinkerton ACLCO/ KnowledgeNow Project

[xwiki-users] Using a JDNI DataSource for connection pooling
by Bryn Jeffries 18 Feb '15

18 Feb '15

I've been exploring connection pooling for an external database, but I'm struggling to use it. I'm running XWiki 6.3 on a Ubuntu server. In /etc/xwiki/context.xml I have <?xml version="1.0" encoding="UTF-8"?> <Context>  <Resource name="jdbc/mydbds" auth="Container" type="javax.sql.DataSource" username="dbuser" password="dbpass" driverClassName="org.postgresql.Driver" url="jdbc:postgresql:alertdb" maxActive="10" maxIdle="4" /> </Context> And I have a symlink to this at /usr/lib/xwiki/WEB-INF/context.xml I'm trying to test that I can access this with a Groovy script. I'm not entirely sure of the correct approach here, but the most successful I've got it with {{groovy}} import groovy.sql.Sql import javax.naming.Context import javax.naming.InitialContext import javax.sql.DataSource Context ctx = new InitialContext(); DataSource dataSource = (DataSource) ctx.lookup("jdbc/mydbds"); def sql = new Sql(dataSource) {{/groovy}} However this fails with javax.naming.NameNotFoundException: Name [jdbc/mydbds] is not bound in this Context. Unable to find [jdbc]. Would anyone be able to tell me whether this is the right sort of way to be going about using a JNDI resource, and what's wrong with my implementation?

[xwiki-users] Wrong parameter for password reset
by lorconksu 17 Feb '15

17 Feb '15

Just want to apologize if this has been asked already, but I was not able to find this in the archive. I have a new instance of XWiki install and everything is working fine, but I am having issue with the "Reset my password" link at the login page. It send the email out fine, but when I click on the link, it takes me to the xwiki with the error message: "Wrong Parameters. Back to the password reset page". I searched the internet and I come up empty, is there a setting I forgot to setup? Please let me know.

[xwiki-users] [AppWithinMinutes] Add Entry by Link from another Page
by Matthias Wegner 06 Jan '15

06 Jan '15

Hi, i need to make the addition of 168 objects to a AppWithinMinutes. I can do it programmatically, because the user should do it in a simple way. Is there an url which i can use or did someone a workaround for it? When not the only way i can think of is to create a new document with a embedded object manually by code.

[xwiki-users] Using a local class within a wiki page
by Bryn Jeffries 26 Dec '14

26 Dec '14

Why does a page containing just the following produce no output?: {{groovy}} class Callee { void hello() { println "hello, world" } } c = new Callee() c.hello() {{/groovy}} I have programming rights, and running scripts in general works fine. It's just when I try to invoke a method from a locally defined class that I hit problems.
