-Started: 18 May 2006.
-
-Description:
-  Performs fuzz-style testing of MediaWiki's parser and forms.
-
-How:
-  - Generate lots of nasty wiki text.
-  - Ask the Parser to render that wiki text to HTML, or ask MediaWiki's forms
-       to deal with that wiki text.
-  - Check MediaWiki's output for problems.
-  - Repeat.
-
-Why:
-  - To help find bugs.
-  - To help find security issues, or potential security issues.
-
-What type of problems are being checked for:
-  - Unclosed tags.
-  - Errors or interesting warnings from Tidy.
-  - PHP errors / warnings / notices.
-  - MediaWiki internal errors.
-  - Very slow responses.
-  - No response from apache.
-  - Optionally checking for malformed HTML using the W3C validator.
-
-Background:
-  Many of the wikiFuzz class methods are a modified PHP port,
-  of a "shameless" Python port, of LCAMTUF'S MANGELME:
-  - http://www.securiteam.com/tools/6Z00N1PBFK.html
-  - http://www.securityfocus.com/archive/1/378632/2004-10-15/2004-10-21/0
-
-Video:
-  There's an XviD video discussing this fuzz tester. You can get it from:
-  http://files.nickj.org/MediaWiki/Fuzz-Testing-MediaWiki-xvid.avi
-
-Requirements:
-  To run this, you will need:
-  - Command-line PHP5, with PHP-curl enabled (not all installations have this
-       enabled - try "apt-get install php5-curl" if you're on Debian to install).
-  - the Tidy standalone executable. ("apt-get install tidy").
-
-Optional:
-  - If you want to run the curl scripts, you'll need standalone curl installed
-       ("apt-get install curl")
-  - For viewing the W3C validator output on a command line, the "html2text"
-       program may be useful ("apt-get install html2text")
-
-Saving tests and test results:
-  Any of the fuzz tests which find problems are saved for later review.
-  In order to help track down problems, tests are saved in a number of
-  different formats. The default filename extensions and their meanings are:
-  - ".test.php" : PHP script that reproduces just that one problem using PHP-Curl.
-  - ".curl.sh"  : Shell script that reproduces that problem using standalone curl.
-  - ".data.bin" : The serialized PHP data so that this script can re-run the test.
-  - ".info.txt" : A human-readable text file with details of the field contents.
-
-Wiki configuration for testing:
-  You should make some additions to LocalSettings.php in order to catch the most
-  errors. Note this configuration is for **TESTING PURPOSES ONLY**, and is IN NO
-  WAY, SHAPE, OR FORM suitable for deployment on a hostile network. That said,
-  personally I find these additions to be the most helpful for testing purposes:
-
-  // --------- Start ---------
-  // Everyone can do everything. Very useful for testing, yet useless for deployment.

-  $wgDBerrorLog = "/root/mediawiki-db-error-log.txt";  // log DB errors, replace with suitable path.
-  $wgShowSQLErrors = true;    // Show SQL errors (instead of saying the query was hidden).
-  $wgShowExceptionDetails = true;  // want backtraces.
-  $wgEnableAPI = true;        // enable API.
-  $wgEnableWriteAPI = true;   // enable API.
-
-  // Install & enable Parser Hook extensions to increase code coverage. E.g.:

-  require_once("extensions/Cite/Cite.php");
-  require_once("extensions/inputbox/inputbox.php");
-  require_once("extensions/Sort/Sort.php");

-  require_once("extensions/CharInsert/CharInsert.php");
-  require_once("extensions/FixedImage/FixedImage.php");
-
-  // Install & enable Special Page extensions to increase code coverage. E.g.:
-  require_once("extensions/Cite/SpecialCite.php");

-  require_once("extensions/Makesysop/SpecialMakesysop.php");
-  require_once("extensions/Renameuser/SpecialRenameuser.php");
-  require_once("extensions/LinkSearch/LinkSearch.php");
-  // --------- End ---------
-
-  If you want to try E_STRICT error logging, add this to the above:
-  // --------- Start ---------
-  error_reporting (E_ALL | E_STRICT);
-  set_error_handler( 'error_handler' );
-  function error_handler ($type, $message, $file=__FILE__, $line=__LINE__) {
-        if ($message == "var: Deprecated. Please use the public/private/protected modifiers") return;
-        print "<br />\n<b>Strict Standards:</b> Type: <b>$type</b>:  $message in <b>$file</b> on line <b>$line</b><br />\n";
-  }
-  // --------- End ---------
-
-  Also add/change this in LocalSettings.php:
-  // --------- Start ---------
-  $wgEnableProfileInfo = true;
-  $wgDBserver = "localhost"; // replace with DB server hostname
-  // --------- End ---------
-
-Usage:
-  Run with "php fuzz-tester.php".
-  To see the various command-line options, run "php fuzz-tester.php --help".
-  To stop the script, press Ctrl-C.
-
-Console output:
-  - If requested, first any previously failed tests will be rerun.
-  - Then new tests will be generated and run. Any tests that fail will be saved,
-       and a brief message about why they failed will be printed on the console.
-  - The console will show the number of tests run, time run, number of tests
-       failed, number of tests being done per minute, and the name of the current test.
-
-TODO:
-  Some known things that could improve this script:
-  - Logging in with cookie jar storage needed for some tests (as there are some
-       pages that cannot be tested without being logged in, and which are currently
-       untested - e.g. Special:Emailuser, Special:Preferences, adding to Watchist).
-  - Testing of Timeline extension (I cannot test as ploticus has/had issues on
-       my architecture).
