How to diagnose causes of site slowness?
by David Gerard 22 Apr '13

22 Apr '13

rationalwiki.org is currently serving pages very slowly. It's intermittent, but when it's slow it's a *slug*. Many users are getting 502 errors from Apache or 503 from the Squids. We have one Linode doing Apache/MySQL/Lucene. It's an 8GB box with 8 cores. (Was 4GB/4 cores, but Linode just doubled everyone's server.) In front of that are two Squids fed by a load balancer. * Sometimes the cause is obvious: when the load average is 30 and top shows a pile of Apaches using up CPU, then it's PHP handling a complex page request. (No, I still haven't made it PHP via fcgid.) * Sometimes it isn't, e.g. this afternoon when the site was running like a slug and load average was 0.8 with nothing amiss in top. * The squids don't show an unusual rate of hits on the site. * We have plenty of memory free - about 4GB on the main box is just sitting in file cache. * php_errors.log only shows up some processes timing out their 30 seconds (which would be the 502s). So where would I start looking to work out what's going on? - d.

Mediwiki 1.20.3 (new install and copies) Apache 2.2.23 PHP 5.4.11 WMH/cPanel on Centos 6 mysql 5.1.68-cll I am moving a few Mediawiki installations from an old server to a new server (same OS) and I thought everything would would work out of the box. But I get a 500 error. In the logs I find...... root@xxxx [xxxxpublic_html/mw]# [Sun Apr 14 10:13:26 2013] [error] [client 86.56.93.42] SoftException in Application.cpp:256: File "/home/xxxx/public_html/mw/index.php" is writeable by group "chmod g-w index.php" does the trick. But then I try an installation.... root@xxx [/home/xxxx/public_html/mw/mw-config]# [Sun Apr 14 10:30:39 2013] [error] [client 86.56.93.42] SoftException in Application.cpp:601: Directory "/home/xxxx/public_html/mw/mw-config" is writeable by group, referer: http://www.xxxxx.uk/mw/ So, now I am confused.... help sought!

Questions marks in URLs being decoded by IIS running ARR load balancer
by Justin Lloyd 19 Apr '13

19 Apr '13

Hi all, We're having a problem with question marks in titles not working (plus-signs as well), which we now believe is due to the URLs being decoded by our load balancers, which are Microsoft Application Request Routing (ARR) running on IIS. For example, http://www.example.com/wiki/What%3F is ending up at our Apache Mediawiki servers as http://www.example.com/wiki/What, resulting in a page not found message since the title has a literal question mark in it. More testing to confirm the behavior would result, for example, in a path like /wiki/What%3Ffoo=bar being parsed into a title of What with a query string of foo=bar. Also, additional question marks get converted into ampersands, e.g. /wiki/What%3Ffoo=bar?baz=blah converts to /wiki/What%3Ffoo=bar&baz=blah. Has anyone else experienced running a wiki behind ARR and dealt with this kind of behavior? Thanks, Justin

How to import templates from Wikipedia?
by Moritz Schubotz 19 Apr '13

19 Apr '13

Hi, I created a copy of the math-related Articles in Wikipedia EN, to demonstrate the LaTeXML math renderer http://demo.formulasearchengine.com/index.php/Great-circle_distance However it looks somehow ugly since the templates are not included. Is there a way to copy or somehow transclude the pages via wgEnableScaryTranscluding without to add a prefix manually. For example in the page above I don't want to change anything to the source. And the template {{Reflist}} should include the template http://en.wikipedia.org/wiki/Template:Reflist Efficiency is not an issue since this is only a demo page.

Question mark after every link?
by Nicola Ferrari (#554252) 17 Apr '13

17 Apr '13

Hi guys. I had to restore my DefaultSettings.php file for some reasons, and now, I'm having a strange problem.. Almost every link has a question mark (?) at the end. e.g. username link in the top right bottom after logging in, is "username?" and the "my topics" link is "mytopics?" Also every category link gives the same problem.. Instead of seeing a red link with "Category" as in the past, now I see a black link "Category?" and only the ? is red. But actually, links are working correctly... Why? Any suggestion on how to solve? Thanks to everybody :) Nick -- +---------------------+ | Linux User #554252 | +---------------------+

l10n_cache table constantly turning-over
by Daniel Renfro 16 Apr '13

16 Apr '13

Cheers MWers, I have a strange problem on my (clustered and load-balanced) Mediawiki instance: the 'l10n_cache' table is getting written to *very* excessively (and constantly.) Mediawiki seems to write the same localization information to the database every 3-5 seconds. This is causing MySQL to constantly write binlog files (for replication to the slaves) which fills the partition after a number of hours. Removing all my extensions does not stop the problem. I have APC installed for opt-code caching, and Memcached installed for caching other things (sessions, parser-stuff, etc.) I assume that this is all due to the constant requests made by the load-balancer to the wiki which in turn cause MW to recalculate the cache. Why is the l10n_cache table getting completely rewritten every few seconds? The cache is not functioning as a cache. I found one thing that will stop this behavior: $wgLocalisationCacheConf['manualRecache'] = true; But this feels wrong because it makes me manually recomputed the l10n cache whenever I update/release. (Yet another thing to tack onto the release process.) There are also some configuration variables which will slow the process ($wgUpdateRowsPerQuery) or cache it to disk ($wgLocalisationCacheConf), but this merely masks the problem. Does anyone have an insight into why the l10n_cache table is getting written to so much? Or why Mediawiki isn't actually *caching* the localization messages in the database?
