Page Variables Extension Recommendation
by Al Johnson 10 Jan '13

10 Jan '13

Hi, There are a few extensions that enable the use of variables in pages/templates. Can anyone recommend a good/stable/safe one? BTW, here's why I need it. I need a unique name/id assigned to each instance of a "multiple" form template so that other dependent subobjects can be associated with each. Thanks, Al

Linode Setup for Mediawiki
by Dan Fisher 10 Jan '13

10 Jan '13

I've been recommended to use the following setup in Linode: >> NGINX, PHP-FPM with APC and MySQL. When I sign up for Linode, it will probably give me options for the type of setup. Which one should I choose? Arch Linux 2012.10 CentOS 6.2 Debian 6 Fedora 17 Gentoo openSUSE 12.1 Slackware 13.37 Ubuntu 10.04 LTS Ubuntu 11.10 Ubuntu 12.04 LTS Ubuntu 12.10 Also is there anything else I should take care of during the sign-up process? thanks Dan On Fri, Nov 30, 2012 at 2:06 AM, Serrano <cserrano(a)gmail.com> wrote: > With Linode every plan has the same virtualized quad core CPU.

Hi, I'm trying to diff two revisions from the History page (not using any diff extensions) and instead I get the following message: (4 intermediate revisions by one user not shown) I'm perplexed. Why can't I see the diff??? Thanks, Al

Re: [MediaWiki-l] URL Being Sanitized?
by Thierry Giroux Veilleux 09 Jan '13

Just to let you know why it does that. When you ask for a webpage, you can add attribute to a webpage prior to its loading which is helpful to send specific data to this webpage. Let say we want to send the attribute title with the value "Main_Page" . Url rewriting, give you the possibility to match one or more of these attributes with the url structure. That's why we match /w/index.php?title=$1 to /wiki/$1 Note that wiki/$1 is parsed as /w/index.php?title=$1 The thing is, even if we rewrite the url, we can add other attributes to the url. You can imagine that : wiki/$1?action=edit is parsed as /w/index.php?title=$1&action=edit As an example : http://en.wikipedia.org/wiki/Main_Page?action=edit is the same as http://en.wikipedia.org/w/index.php?title=Main_Page&action=edit Therefore, if you send something like /wiki/What's the matter folks? Apache himself will treat this url as /w/index.php?title=What's the matter folks& and /wiki/What's the matter folks?action=edit will be parsed as /w/index.php?title=What's the matter folks&action=edit and so on. the action=edit gives you the edit form of an article with the specified title. Now that you understand why it's not working, the only way to put an "?" in an attribute is to put it in an attribute itself without url rewritting : /w/index.php?title=What's the matter folks? As the server waits an & to parse the next attribute it will include the question mark in the title attribute. However, if an attribute is part of the URL-rewriting, you can only include a question mark with the url encoding of it. (%3F) You will notice that the % alone or without valid letters following it will not work either. As it is used for url encoding. Note that when you do a link in the wiki [[What's the matter folks?]] the parser will parse it as What's the matter folks%3F http://www.w3schools.com/tags/ref_urlencode.asp Thierry

Oh I misread you. I think you are right, this is a nginx issue. May be they used something like a Virtual Host configuration with Proxy_Pass attribute in a location and had mistakely added a trailing to the adress "/". which cause a decode of all the url. It happened to me once. ...Or something like that. Thierry

URL Being Sanitized?
by Tom 08 Jan '13

08 Jan '13

I'm trying to figure out why one of my wikis is having problems with page titles which include the ? character in page titles. They work just fine on my localhost but when uploaded they will not appear correctly. All the settings appear to be the same in the php.ini file. On the hosted server even when ? is end of a title it still will not show even though the URL indicates it should be there with the %3F. I'm starting to wonder if the host is running URL requests through some type of sanitizer and blocking characters. Thoughts appreciated. Thanks Tom

Hey all, I'm happy to announce the immediate release of Diff 0.4 [0]. Notable changes in this version where moving the diff creation code from static methods in the diff representation classes to dedicated differ classes and the introduction of patching functionality. Next to several code quality and design improvements, a lot of tests where also added. The documentation on mediawiki.org got updated accordingly and new examples where added. [0] https://www.mediawiki.org/wiki/Extension:Diff Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. --
