Version 1.2.0, 2004-03-24

edit

This is the new production release; it is more or less in sync with what is running on Wikipedia right now. However this software is provided with NO WARRANTY of fitness for any purpose; there may be some interesting bugs, it may eat all your data, and documentation may not be up to date. New features in 1.2:

  • In-place web-based installation [experimental!] Note that maintenance functions are not yet available through the web install script.
  • Image resizing/thumbnail generation
  • Stricter upload file extension blacklist and whitelist options
  • More flexible blocking system; time period may be set
  • Handier sysop account management. An account marked "bureaucrat" may assign sysop access to other accounts via Special:Makesysop. (The exact details of this may change in the future)
  • Support for a squid cache with explicit purging of cached anon pages
  • Optional compression of old revision text (requires zlib support)
  • Fuzzy title search (experimental, requires memcached)
  • Page rendering cache (experimental)
  • Editing toolbar to demonstrate wiki syntax to newbies (off by default in user preferences)
  • Support for authenticated SMTP outgoing e-mail (experimental)
  • It's now possible to assign sysop accounts from within the wiki. An account with this ability must be labeled with the "bureaucrat" privilege, such as the 'Developer' account created by the install. Fixes and tweaks:
  • Now works with register_globals off!
  • Should work out of the box on MySQL 3.2.x again. On 4.x set $wgEnablePersistentLC = true; to turn on the link cache table for a slight rendering speed boost.
  • Should work on PHP 5.0 beta (not thoroughly tested)
  • Works with short tags disabled.
  • rebuildMessages.php can now selectively update new messages, or overwrite everything.
  • Some layout fixes for RTL languages.
  • Now includes arrow icons for enhanced recent changes.
  • Various bug fixes.

Behavior changes

edit
  • wiki.phtml and redirect.phtml are now renamed to index.php and redirect.php The old names are provided too for compatibility, but make sure they don't conflict if you've been putting other files in your wiki.
  • Uploaded filenames are more strictly checked than before. See bits in DefaultSettings.php to tweak this behavior to your needs.
  • Database messages are now enabled by default, so the interface messages can be tweaked through the wiki with a sysop account. Disable this if you don't want the performance hit.

Database changes

edit

An index was added to recentchanges table to speed up Newpages (patch-rc-newindex.sql for manual updaters). Expiration date field has been added to ipblocks table (patch-ipb_expiry.sql for manual updaters). The links tables have slightly stricter indexes. ('links' and 'brokenlinks' are not changed on existing installations.)

Known problems

edit

The version 1.1.0 LocalSettings.sample file included the setting $wgCategoryMagic = true; this setting is for an experimental feature that _does not work correctly_. If you have it left over, turn it off or you'll see mysterious problems with vanishing links. There may be problems with session handling on some systems. Checking the "remember my password" box may help as a temporary workaround. If you receive "Cannot load input file" errors when trying to get at the wiki after installation, make the following changes: 

 in LocalSettings.php change the line something like this:
   $wgArticlePath  = "/wiki/index.php/$1";
 to:
   $wgArticlePath  = "/wiki/index.php?title=$1";
 in index.php, remove these lines:
   if( isset( $_SERVER['PATH_INFO'] ) ) {
       $title = substr( $_SERVER['PATH_INFO'], 1 );
   } else {
       $title = $_REQUEST['title'];
   }

Version 1.1.0, 2003-12-08

edit

This is the new production release. Any following 1.1.x releases are expected to contain only bug fixes; developments of new features will go towards a 1.2.0 release. New features in 1.1:

  • New wiki table syntax: http://meta.wikipedia.org/wiki/MediaWiki_User%27s_Guide:_Using_tables
  • User-editable interface messages: http://meta.wikipedia.org/wiki/MediaWiki_namespace
  • XML-wrapped page source export with optional history: http://meta.wikipedia.org/wiki/XML_import_and_export (There is not yet an import function!)

New translations:

  • fi - Finnish

Database changes

edit

"linkscc" table added. If upgrading manually (rather than with update.php), run maintenance/archives/patch-linkscc.sql to create the table. Older releases were dated snapshots from the old 'stable' branch:

mediawiki-20031107

edit
  • Fixed various bugs!
  • Some speed improvements from tweaks to the table indexes
  • Limited support for memcached (see below)
  • New translations (see below)
  • Interwiki link data now kept in database for flexibility
  • Friendlier read-only source view if asked to edit a page when the db is locked or the page is protected.
  • Normal IP blocks auto-expire after 24 hours
  • Optional support for blocking usernames
  • Uploads disabled by default (see below)

Security note

edit

Uploads are now disabled by default. If you've set up a secure configuration you can reenable uploads by putting: $wgDisableUploads = false; into LocalSettings.php. Earlier versions of MediaWiki included a bug that potentially allows logged- in users to delete arbitrary files in directories writable by the web server user by manually feeding false form data; this is now fixed. As a reminder, disable PHP script execution in the upload directory! You may also wish to serve HTML pages as plaintext to prevent cookie- stealing JavaScript attacks. Example Apache config fragment: 

 <Directory "/Library/MediaWiki/web/upload">
     # Ignore .htaccess files
     AllowOverride None
     
     # Serve HTML as plaintext
     AddType text/plain .html .htm .shtml
     
     # Don't run arbitrary PHP code.
     php_admin_flag engine off
     
     # If you've other scripting languages, disable them too.
  </Directory>

Database updates

edit

If you're using update.php, the necessary database changes should be made automatically. To manually upgrade your database from the 2003-08-29 release, run the following SQL scripts from the maintenance subdirectory: archives/patch-ipblocks.sql archives/patch-interwiki.sql archives/patch-indexes.sql interwiki.sql To copy in the Wikipedia language-prefix interwikis as well, add: wikipedia-interwiki.sql

Translations

edit

New interface localization files are included for:

  • fy Frisian
  • ro Romanian
  • sl Slovene
  • sq Albanian
  • sr Serbian

Memcached

edit

Memcached is a distributed cache system. See http://www.danga.com/memcached/ MediaWiki can optionally use memcached to store some data between calls to reduce load on the database. Currently this is limited to user and talk page notification data, interwiki prefix/URL matches, and the UTF-8 conversion tables. MediaWiki includes version 1.0.10 of the (GPL'd) PHP memcached client by Ryan Gilfether; if memcached is disabled it acts as a dummy object with minimal overhead. To use memcached you'll need PHP installed with sockets support (this is notin the default configure options). See docs/memcached for some more details. Additionally, you can store login session data in memcached instead of the local filesystem, which can help to enable load-balancing by letting login sessions transparently work on multiple front-end web servers. (The primary other issue is with uploads, which requires some care in handling.) To enable this, set $wgSessionsInMemcached = true; and set $wgCookieDomain appropriately if exposing multiple hostnames. This system is new and may be volatile; login sessions will fail dramatically if memcached is unavailable when this option is turned on.

Online documentation

edit

Documentation for both end-users and site administrators is currently being built up on Meta-Wikipedia, and is covered under the GNU Free Documentation License: http://meta.wikipedia.org/wiki/MediaWiki_User%27s_Guide

Mailing list

edit

A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list: http://mail.wikipedia.org/mailman/listinfo/mediawiki-l

UseModWiki import script

edit

A stripped-down UseModWiki import script is available in the maintenance subdirectory. It is incomplete and requires a lot of manual clean-up, but does function for the brave and pure of heart.

Test suite removed

edit

The unmaintained Java-based test suite has been removed from the tarball release. If you really want it you can check it out from CVS.
