RELEASE-NOTES-1.29

   1 == MediaWiki 1.29 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.29 ===
   9 * Default cookie expiration time has been reduced to 30 days. Login cookie
  10   expiration time is kept at 180 days.
  11 * A new configuration variable has been added: $wgCookieSetOnAutoblock. This
  12   determines whether to set a cookie when a user is autoblocked. Doing so means
  13   that a blocked user, even after logging out and moving to a new IP address,
  14   will still be blocked.
  15 * The resetpassword right and associated password reset capture feature has
  16   been removed.
  17 * The $error parameter to the EmailUser hook should be set to a Status object
  18   or boolean false. This should be compatible with at least MediaWiki 1.23 if
  19   not earlier. Returning a raw HTML string is now deprecated.
  20 * The $message parameter to the ApiCheckCanExecute hook should be set to an
  21   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  22   code for ApiBase::parseMsg() will no longer work.
  23 * ApiBase::$messageMap is no longer public. Code attempting to access it will
  24   result in a PHP fatal error.
  25 * $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
  26   policies.
  27 * Subpages are now enabled by default in the Template namespace. Set
  28   $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
  29 * $wgRunJobsAsync is now false by default (T142751). This change only affects
  30   wikis with $wgJobRunRate > 0.
  31
  32 === New features in 1.29 ===
  33 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
  34   if they move to a new IP address. This is disabled by default.
  35 * Added ILocalizedException interface to standardize the use of localized
  36   exceptions, largely so the API can handle them more sensibly.
  37 * Blocks created automatically by MediaWiki, such as for configured proxies or
  38   dnsbls, are now indicated as such and use a new i18n message when displayed.
  39 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  40   downloading the XML dump during a transwiki import in seconds.
  41 * Parser limit report is now available in machine-readable format to JavaScript
  42   via mw.config.get('wgPageParseReport').
  43 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  44   from certain IP ranges (e.g. private IPs).
  45 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  46   of the page being parsed.
  47 * Added JavaScript that provides as-you-type suggestions for reason
  48   on the block, delete and protect forms.
  49
  50 === External library changes in 1.29 ===
  51
  52 ==== Upgraded external libraries ====
  53 * Updated QUnit from v1.22.0 to v1.23.1.
  54
  55 ==== New external libraries ====
  56
  57 ==== Removed and replaced external libraries ====
  58
  59 === Bug fixes in 1.29 ===
  60 * (T62604) Core parser functions returning a number now format the number according
  61   to the page content language, not wiki content language.
  62
  63 === Action API changes in 1.29 ===
  64 * Submitting sensitive authentication request parameters to action=clientlogin,
  65   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  66   in the query string is now an error. They should be submitted in the POST
  67   body instead.
  68 * The capture option for action=resetpassword has been removed
  69 * action=clearhasmsg now requires a POST.
  70 * (T47843) API errors and warnings may be requested in non-English languages
  71   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  72 * API error codes may have changed. Most notably, errors from modules using
  73   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  74 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  75   'errorformat'.
  76 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  77   'errors' subelements (as applicable) instead of 'message'.
  78 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  79 * action=move now reports errors when moving the talk page as an array under
  80   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  81   'talkmove-error-info'. The format for subpage move errors has also changed.
  82 * action=revisiondelete no longer includes a "rendered" property on warnings
  83   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  84   output.
  85 * action=rollback no longer returns a "messageHtml" property. Use
  86   errorformat=html if you're wanting HTML formatting of error messages.
  87 * action=upload now reports optional stash failures as an array under key
  88   'stasherrors' rather than a 'stashfailed' text string.
  89 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  90   no longer returns a 'message' on success.
  91 * Added action=validatepassword to validate passwords for the account creation
  92   and password change forms.
  93
  94 === Action API internal changes in 1.29 ===
  95 * New methods were added to ApiBase to handle errors and warnings using i18n
  96   keys. Methods for using hard-coded English messages were deprecated:
  97   * ApiBase::dieUsage() was deprecated
  98   * ApiBase::dieUsageMsg() was deprecated
  99   * ApiBase::dieUsageMsgOrDebug() was deprecated
 100   * ApiBase::getErrorFromStatus() was deprecated
 101   * ApiBase::parseMsg() was deprecated
 102   * ApiBase::setWarning() was deprecated
 103 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 104   result in a PHP fatal error.
 105 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 106   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 107   code for ApiBase::parseMsg() will no longer work.
 108 * UsageException is deprecated in favor of ApiUsageException. For the time
 109   being ApiUsageException is a subclass of UsageException to allow things that
 110   catch only UsageException to still function properly.
 111 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 112   ApiErrorFormatter_BackCompat, note that the result format has changed and
 113   various methods now take a module path rather than a module name.
 114 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 115   from the message key, and maps some message keys for backwards compatibility.
 116
 117 === Languages updated in 1.29 ===
 118
 119 MediaWiki supports over 350 languages. Many localisations are updated
 120 regularly. Below only new and removed languages are listed, as well as
 121 changes to languages because of Phabricator reports.
 122
 123 * Based as always on linguistic studies on intelligibility and language
 124   knowledge by geography, language fallbacks have been expanded. When a
 125   translation is missing in the user's preferred interface language, the
 126   corresponding translation for the fallback language will be used instead.
 127   English will only be used as last resort when there are no translations.
 128   Some configurations (such as date formats and gender namespaces) have also
 129   been updated when using the fallback language's configuration was inadequate.
 130   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 131   hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
 132
 133 ==== No fallback for Ukrainian ====
 134 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 135   language will now use the default fallback language: English. When a translation
 136   to Ukrainian is not available, an English string will be shown.
 137
 138 === Other changes in 1.29 ===
 139 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 140   SearchEngineFactory::getSearchEngineClass() instead.
 141 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 142   required as all sessions are stored in Object Cache now.
 143 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 144   Status return type is deprecated.
 145 * User::edits() (deprecated in 1.21) was removed.
 146 * Xml::escapeJsString() (deprecated in 1.21) was removed.
 147 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
 148   were removed.

 150   were removed.

 159 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
 160 * Class FSRepo (deprecated in 1.19) was removed.
 161 * WebRequest::checkSessionCookie() (deprecated in 1.27) was removed. Use
 162   \MediaWiki\Session\SessionManager::singleton()->getPersistedSessionId() instead.
 163 * Class ImageGallery (deprecated in 1.22) was removed.
 164   Use ImageGalleryBase::factory instead.
 165 * Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class instead.
 166 * Hook UnknownAction (deprecated in 1.19) was actually deprecated (it will now
 167   emit warnings). Create a subclass of Action and add it to $wgActions instead.
 168 * WikiRevision::getText() (deprecated since 1.21) is no longer marked deprecated.
 169 * Linker::getInterwikiLinkAttributes() (deprecated since 1.25) was removed.
 170 * Linker::getInternalLinkAttributes() (deprecated since 1.25) was removed.

 174 == Compatibility ==
 175
 176 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 177 HHVM 3.6.5 or later.
 178
 179 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 180 support for them is somewhat less mature. There is experimental support for
 181 Oracle and Microsoft SQL Server.
 182
 183 The supported versions are:
 184
 185 * MySQL 5.0.3 or later
 186 * PostgreSQL 8.3 or later
 187 * SQLite 3.3.7 or later
 188 * Oracle 9.0.1 or later
 189 * Microsoft SQL Server 2005 (9.00.1399)
 190
 191 == Upgrading ==
 192
 193 1.29 has several database changes since 1.28, and will not work without schema
 194 updates. Note that due to changes to some very large tables like the revision
 195 table, the schema update may take quite long (minutes on a medium sized site,
 196 many hours on a large site).
 197
 198 If upgrading from before 1.11, and you are using a wiki as a commons
 199 repository, make sure that it is updated as well. Otherwise, errors may arise
 200 due to database schema changes.
 201
 202 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 203 new database fields are filled with data.
 204
 205 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 206 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 207 with MediaWiki 1.21.
 208
 209 Don't forget to always back up your database before upgrading!
 210
 211 See the file UPGRADE for more detailed upgrade instructions.
