= Dave Golby's Test Page =
This is my home page, mainly used for testing ideas and resolving installationand configuration problems.

== Testing the Security Features ==
I've set up a special area for testing the LockDown facility.  You can find it [[Test_LockDown|here]].

== Installation and Configuration of Latex == 

Some equation tests.

First of all, good old Einstein's famous mass-energy equivalence:

<math>

   E = m c^{2}
</math>

Remember the good old days of Newtonian absolute space and time? (sigh...)

<math>
   F_{12} = \frac{Gm_{1}m_{2}}{R_{12}^{2}}
</math>

a totally made up equation to test partial differential symbols:

<math>
   \frac{\partial^{2} y(x,t)}{\partial t^{2}} = f(t) g(x)
</math>

and another (Ludwig Boltzmann, rest in peace...)

<math>
   S =  k \log(W)
</math>

==== Notes ====
* After much struggle, the above equations should be rendered properly if texvc is working and the MediaWiki is configured correctly.

* Had to install MinGW32 for the basic compilation tools (make in this case). MinGW32 provides an application manager to download and install the components.  These are stored in e:\mingw

* The source files for texvc are written in Caml.  So another package is required called Objective Caml to compile these up.  This is also installed on the E: drive.  

* MediaWiki has a Math folder in which various source programs for texvc are kept.  The make file in this folder must be executed in order for the texvc.bc code to be generated.

** '''NOTE''' Both Objective Caml bin and Mingw bin folders must be in the path
** When compiling from the DOS shell, use CAMLLIB=e:\objective caml\lib to enable CAML to pick up the various auxiliary files

* The render.ml file needs to be modified.  Consult the page at [http://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Windows#Mathematics_Support]

* The Math.php file also needs to be modified.  Read the instructions for replacing certain code sections at the above link

* I also had to open up all sorts of permissions to different users on the images folder.  Not good form but this was required to get it to work.

* A good source of info for LaText within MediaWiki can be found at [http://meta.wikimedia.org/wiki/Help:Formula#Continuation_and_cases here].

== Installation and Configuration of PHP on Windows ==
* I would recommend using the zip installation, NOT the Windows installer
* Install PHP to C:\PHP or similar directory with no whitespaces in its pathname
* Use mmc to change the IIS setings:
** In the ISAPI Filters tab set up a PHP ISAPI Filter using c:\php\php5isapi.dll
** Make sure the Web Service extension for PHP is enabled with C:\php\php5isapi.dll
** In the Home Directory mmc tab, click on "Configuration..." and add a new extension .php to the list of supported extensions.  Set the executable to c:\php\php5isapi.dll
* Use the PHPRC system-wide environment variable to set the PHP installation directory
* It may be required to change the permissions of the directory so that the IUSR_<machine name> has access to the folder (eg, for write,read,execute...)
* Set up the c:\php\php.ini file
<pre>

<?php

phpinfo();

?>

== Internal Variables ==
These are some internal variables that should be rendered correctly at run-time.

Consult the article [http://meta.wikimedia.org/wiki/Help:Variable here] for more info on these variables.

Here are some examples of these variables:
* {{SITENAME}} The name of the site (SITENAME)
* {{SERVER}} The name of the server (SERVER)
* {{FULLPAGENAME}} The full name of the current page (FULLPAGENAME)
* {{ARTICLEPAGENAME}} The name of the article (ARTICLEPAGENAME)
* [{{SERVER}}/index.php?title={{FULLPAGENAME}}&printable=yes Click this to get a printable version of this page]
* The current user is {{CURRENTUSER}}

== Templates ==
Test Templates:
* [[Template:Letter|Letter template]]
* [[Template:ACArticle|AC Article template]]
* [[Template:UFRArticle|UFR Article template]]
* [[Template:Test_Form_Sample|A test template for checking the Form extension]]
Note that these Templates should be substituted into the page.

Here are some test pages that use templates I've developed
* [[Test_Let1|Test Letter 1]]
* [[Test_AC1|Test AC]]
* [[Test_AC_CFDSim|Test AC CFD Simulations]]

== Simple Forms ==
Click one this link to create a form.  It uses the MediaWiki extension described [http://www.mediawiki.org/wiki/Extension:Form here].  The following form is provided as a test by the Form extension.

* [[Special:Form/Sample]]

The sample form definition can be found [[MediaWiki:Sample-form|here]]. The template used can be found [[Template:Test_Form_Sample|here]].

My own test form uses the AC Abstract template.  Unfortunately it doesn't work properly at the moment. 
* [[Special:Form/ACAbstract|Click this to generate a new AC Abstract Page]]
* [[MediaWiki:ACAbstract-form|The form definition for the AC Abstract]]
* [[Template:ACAbstract|The Template for the AC Abstract page]]

Some sample pages created using the Abstract page form:
* [[Abstract_AC_123_01]]

== HTMLets ==
This is a test area for HTMLets.
* [[Test_DG_HTMLet_Form|Simple Form using HTMLets]]
* [[Test_Ercoftac_AC_Article_Form|A test form for creating Ercoftac AC and UFR Articles]]

== Towards a Content Management Extension ==
These are links to pages concerned with scoping out work for a content management system.  This is a proposed extension that would provide Ercoftac Editorial team members with tools for creating, moving and deleting Ercoftac articles.  Ercoftac articles are a collection of MediaWiki pages.

* [[Dev:Experiments_With_MySQL|Tests and experiments with MySQL]]
* [[Dev:Content_Management_Framework|Wiki Content Management Framework]]

== Email Confirmation and Access Control ==
Currently looking at limiting edit privileges to users who have a registered AND confirmed email address.  This would help to prevent any bots from registering themselves.

Today I registered a new user [[User:Test.Account|Test Account user]] with a valid email address.  The registered email was received at the expected address. 

It turns out that a reply to this email was not required to complete the registration of the new user.  That is, in principle a user without a confirmed email address can continue to use the Wiki.  However, if the access controls on a page demand it, he/she may not be able to edit the page.  

A user who elects to confirm his email address should be added to an 'emailconfirmed' user group, and it is by using this group that edit-controls can be placed on particular groups.  To date it has not been possible to add users to this group: a check of the User List page shows that there are no members of this group as yet.

A forum post recommends the following PHP code.  To restrict editing rights to registered users, the following should be added to LocalSettings.php:

<pre>
$wgGroupPermissions['*' ]['edit'] = false; # Disallows editing by users. 
$wgGroupPermissions['emailconfirmed']['edit'] = true; # Allows editing by those with confirmed e-mails. 

</pre>

It's possible that this won't work as there are individual edit settings for particular groups that might override this setting.  What is required is a means of adding users to two groups and ensuring that the permissions are AND-ed, ie, a user needs to be both in the Submitter group AND in the 'emailconfirmed' group before he is allowed to edit a page.
