  11 Description:
  12   Performs fuzz-style testing of MediaWiki's parser and forms.
  13
  14 How:
  15   - Generate lots of nasty wiki text.
  16   - Ask the Parser to render that wiki text to HTML, or ask MediaWiki's forms
  17     to deal with that wiki text.
  18   - Check MediaWiki's output for problems.
  19   - Repeat.
  20
  21 Why:
  22   - To help find bugs.
  23   - To help find security issues, or potential security issues.
  24
  25 What type of problems are being checked for:
  26   - Unclosed tags.
  27   - Errors or interesting warnings from Tidy.
  28   - PHP errors / warnings / notices.
  29   - MediaWiki internal errors.
  30   - Very slow responses.
  31   - No response from apache.
  32   - Optionally checking for malformed HTML using the W3C validator.
  33
  34 Background:
  35   Many of the wikiFuzz class methods are a modified PHP port,
  36   of a "shameless" Python port, of LCAMTUF'S MANGELME:
  37   - http://www.securiteam.com/tools/6Z00N1PBFK.html
  38   - http://www.securityfocus.com/archive/1/378632/2004-10-15/2004-10-21/0
  39
  40 Video:
  41   There's an XviD video discussing this fuzz tester. You can get it from:
  42   http://files.nickj.org/MediaWiki/Fuzz-Testing-MediaWiki-xvid.avi
  43
  44 Requirements:
  45   To run this, you will need:
  46   - Command-line PHP5, with PHP-curl enabled (not all installations have this
  47     enabled - try "apt-get install php5-curl" if you're on Debian to install).
  48   - the Tidy standalone executable. ("apt-get install tidy").
  49
  50 Optional:
  51   - If you want to run the curl scripts, you'll need standalone curl installed
  52     ("apt-get install curl")
  53   - For viewing the W3C validator output on a command line, the "html2text"
  54     program may be useful ("apt-get install html2text")
  55
  56 Saving tests and test results:
  57   Any of the fuzz tests which find problems are saved for later review.
  58   In order to help track down problems, tests are saved in a number of
  59   different formats. The default filename extensions and their meanings are:
  60   - ".test.php" : PHP script that reproduces just that one problem using PHP-Curl.
  61   - ".curl.sh"  : Shell script that reproduces that problem using standalone curl.
  62   - ".data.bin" : The serialized PHP data so that this script can re-run the test.
  63   - ".info.txt" : A human-readable text file with details of the field contents.
  64
  65 Wiki configuration for testing:
  66   You should make some additions to LocalSettings.php in order to catch the most
  67   errors. Note this configuration is for **TESTING PURPOSES ONLY**, and is IN NO
  68   WAY, SHAPE, OR FORM suitable for deployment on a hostile network. That said,
  69   personally I find these additions to be the most helpful for testing purposes:

 128   require_once("extensions/LinkSearch/LinkSearch.php");
 129   // --------- End ---------
 130
 131   If you want to try E_STRICT error logging, add this to the above:
 132   // --------- Start ---------
 133   error_reporting (E_ALL | E_STRICT);
 134   set_error_handler( 'error_handler' );
 135   function error_handler ($type, $message, $file=__FILE__, $line=__LINE__) {
 136      if ($message == "var: Deprecated. Please use the public/private/protected modifiers") return;
 137      print "<br />\n<b>Strict Standards:</b> Type: <b>$type</b>:  $message in <b>$file</b> on line <b>$line</b><br />\n";
 138   }
 139   // --------- End ---------
 140
 141   Also add/change this in AdminSettings.php:
 142   // --------- Start ---------
 143   $wgEnableProfileInfo = true;
 144   $wgDBserver = "localhost"; // replace with DB server hostname
 145   // --------- End ---------
 146
 147 Usage:
 148   Run with "php fuzz-tester.php".
 149   To see the various command-line options, run "php fuzz-tester.php --help".
 150   To stop the script, press Ctrl-C.
 151
 152 Console output:
 153   - If requested, first any previously failed tests will be rerun.
 154   - Then new tests will be generated and run. Any tests that fail will be saved,
 155     and a brief message about why they failed will be printed on the console.
 156   - The console will show the number of tests run, time run, number of tests
 157     failed, number of tests being done per minute, and the name of the current test.
 158
 159 TODO:
 160   Some known things that could improve this script:
 161   - Logging in with cookie jar storage needed for some tests (as there are some
 162     pages that cannot be tested without being logged in, and which are currently
 163     untested - e.g. Special:Emailuser, Special:Preferences, adding to Watchist).
 164   - Testing of Timeline extension (I cannot test as ploticus has/had issues on
 165     my architecture).

 209 Example:
 210   If you wanted to fuzz test a nightly MediaWiki checkout using cron for 1 hour,
 211   and only wanted to be informed of errors, and did not want to redo previously
 212   failed tests, and wanted a maximum of 100 errors, then you could do:
