The test suite is +written in Java, using several external libraries. + +Recommended versions are: Apache 1.3.26 or later; MySQL +2.23.51 or later; PHP 4.2.2 or later. The installation at +wikipedia.org also uses the APC caching software, but +that's entirely optional and doesn't affect anything else. + +The math rendering functions are more complex, and will +probably only work on Linux. Objective CAML (probably +3.06 or later) is required to compile texvc, but produces +static binaries. TeTeX and ImageMagick are required at +runtime, and ImageMagick requires GhostScript. These are +present in most Linux distributions. + +Before installing the software, you must copy the file +"LocalSettings.sample" to "LocalSettings.php", and +"AdminSettings.sample" to "AdminSettings.php", and +customize both of the php files to your local setup +(things like installation parh, passwords, etc.) The +script install.php in the maintenance directory can then +be run to install the software. + +Here are some more notes on building a system from scratch +the way it was done for the Wikipedia server: + +Downloads: + + gcc-2.95.3.tar.gz + mysql-3.23.51.tar.gz + libiconv-1.8.tar.gz + apache_1.3.26.tar.gz + php-4.2.1.tar.gz + apc-cvs.tar.gz + +And for math support: + ocaml-3.06.tar.gz + (TeTeX, ImageMagick, and GhostScript come with most Linux distros) + +1. MySQL strongly recommends using gcc 2.95 to compile MySQL. + RedHat Linux comes with 2.96 by default, so you'll have to install + 2.95 first. Use "../gcc*/configure --enable-shared" If your Linux + installation doesn't use gcc 2.96 you can skip this step. + +2. Install MySQL source; add "mysql" user and group. Make sure the + directory into which you installed gcc 2.95 appears before the + directory of gcc 2.96 in your path. Configure with: + + FLAGS="-O3 -mpentiumpro" CXX=gcc CXXFLAGS="-O3 -mpentiumpro -felide-constructors -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local/mysql --enable-assembler --with-mysqld-ldflags=-all-static --disable-shared --with-extra-charset=complex + + Edit the file myisam/ftdefs.h, changing the define for minimum word + length for fulltext indexing: #define MIN_WORD_LEN 2. Update + $wgDBminWordLen in LocalSettings.php to reflect this. Build and + install according to instructions. Make root user as recommended; + the root password will be required for the wiki installation script. + +3. Unpack the phase3.zip source distribution, or check out the "phase3" + module from CVS. Copy LocalSettings.sample to LocalSettings.php, + AdminSettings.sample to AdminSettings.php, and customize them for + things like local paths and passwords. If desired, update + FulltextStoplist.php from the MySQL sources if you have customized + MySQL's stop list. + +4. Optionally, install libiconv (http://www.gnu.org/software/libiconv/). + This will be used by some language packages for converting + native-charset URLs to and from UTF-8. If you're running an + English-only wiki, this won't be necessary. + +5. Unpack Apache distribution and begin configuring, but don't finish + build yet. Configure with something like: + + OPTIM='-O2 -mpentiumpro' ./configure --with-layout=Apache + +6. If you'll want to use Apache's mod_rewrite to make page-viewing URLs + look like static links (as wikipedia.org does), install the included + patch "apache-ampersand.diff" which is needed to support page titles + with ampersands in them: + + patch -p0 < /path/to/maintenance/apache-ampersand.diff + +7. Unpack and configure PHP. Configure with something like: + + ./configure --enable-apc --with-mysql=/usr/local/mysql --with-iconv=/usr/local/lib --with-apache=/home/lee/src/apache_1.3.26 + + (using your own local paths, of course). Build and install as + instructed. Set "register_globals" on in the config file. + +8. Finish building Apache. Configure with something like: + + OPTIM='-O2 -mpentiumpro' ./configure --with-layout=Apache --enable-module=rewrite --activate-module=src/modules/php4/libphp4.a + + Update httpd.conf as needed for your site. For example: + + + AddType application/x-httpd-php .php .php4 .phtml + AddType application/x-httpd-php-source .phps + + + php_admin_flag engine off + + + + php_admin_flag engine on + + + RewriteEngine On + RewriteMap ampescape int:ampescape + RewriteRule ^/wiki/(.*)$ /wiki.phtml?title=${ampescape:$1} [L] + + It is *seriously* recommended that you configure the webserver + to disable running of PHP scripts except in the script directories + (the "php_admin_flag engine off/on" directives above) to prevent + the uploading and running of malicious scripts. + +9. Optionally, install APC, following standard instructions for + installing as a Zend extension. + +10. If using embedded TeX support, be sure TeX and ImageMagick are + installed (they are common on most Linux distros and freely + downloadable). Also get and install OCaml according to its + instructions. + + You'll need to compile the texvc helper script; enter the math + subdirectory of the source tree and run "make". + + If you don't want embedded TeX support, disable it by setting + + $wgUseTex = false; + + in LocalSettings.php + +11. You should now be able to run the install.php script. Use PHP in + command-line mode, i.e., type "php install.php". Should be run as + root, or as a user or group able to create files and directories + in the installation tree. + +12. If you have Java installed and running, install the "ant" package + from Apache (http://ant.apache.org/) and run ant in the testsuite + directory to build the tests. Copy wikitest.prefs.sample to + wikitest.prefs, and edit to reflect your local settings. Then + "./run WikiSuite -o -b" will run the whole test suite and report. + +---- + +Don't forget that this is pre-release software under development! +Chances are good there's a crucial step that hasn't made it +into the documentation.

The class in instantiated from one of +these forms and can be queried for the others, and for other +attributes of the title. This is intended to be an +immutable "value" class, so there are no mutator functions. + +To get a new instance, call one of the static factory +methods WikiTitle::newFromURL(), WikiTitle::newFromDBKey(), +or WikiTitle::newFromText(). Once instantiated, the +other non-static accessor methods can be used, such as +getText(), getDBKey(), getNamespace(), etc. + +The prefix rules: a title consists of an optional Interwiki +prefix (such as "m:" for meta or "de:" for German), followed +by an optional namespace, followed by the remainder of the +title. Both Interwiki prefixes and namespace prefixes have +the same rules: they contain only letters, digits, space, and +underscore, must start with a letter, are case insensitive, +and spaces and underscores are interchangeable. Prefixes end +with a ":". A prefix is only recognized if it is one of those +specifically allowed by the software. For example, "de:name" +is a link to the article "name" in the German Wikipedia, because +"de" is recognized as one of the allowable interwikis. The +title "talk:name" is a link to the article "name" in the "talk" +namespace of the current wiki, because "talk" is a recognized +namespace. Both may be present, and if so, the interwiki must +come first, for example, "m:talk:name". If a title begins with +a colon as its first character, no prefixes are scanned for, +and the colon is just removed. Note that because of these +rules, it is possible to have articles with colons in their +names. "E. Coli 0157:H7" is a valid title, as is "2001: A Space +Odyssey", because "E. Coli 0157" and "2001" are not valid +interwikis or namespaces. Likewise, ":de:name" is a link to +the article "de:name"--even though "de" is a valid interwiki, +the initial colon stops all prefix matching. + +Character mapping rules: Once prefixes have been stripped, the +rest of the title processed this way: spaces and underscores are +treated as equivalent and each is converted to the other in the +appropriate context (underscore in URL and database keys, spaces +in plain text). "Extended" characters in the 0x80..0xFF range +are allowed in all places, and are valid characters. They are +encoded in URLs. Other characters may be ASCII letters, digits, +hyphen, comma, period, apostrophe, parentheses, and colon. No +other ASCII characters are allowed, and will be deleted if found +(they will probably cause a browser to misinterpret the URL). +Extended characters are _not_ urlencoded when used as text or +database keys. + +Character encoding rules: TODO + +Canonical forms: the canonical form of a title will always be +returned by the object. In this form, the first (and only the +first) character of the namespace and title will be uppercased; +the rest of the namespace will be lowercased, while the title +will be left as is. The text form will use spaces, the URL and +DBkey forms will use underscores. Interwiki prefixes are all +lowercase.
