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 expiration time is
  10   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 policies.
  26 * Subpages are now enabled by default in the Template namespace. Set
  27   $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
  28 * $wgRunJobsAsync is now false by default (T142751). This change only affects
  29   wikis with $wgJobRunRate > 0.
  30
  31 === New features in 1.29 ===
  32 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
  33   they move to a new IP address. This is disabled by default.
  34 * Added ILocalizedException interface to standardize the use of localized
  35   exceptions, largely so the API can handle them more sensibly.
  36 * Blocks created automatically by MediaWiki, such as for configured proxies or
  37   dnsbls, are now indicated as such and use a new i18n message when displayed.
  38 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  39   downloading the XML dump during a transwiki import in seconds.
  40 * Parser limit report is now available in machine-readable format to JavaScript
  41   via mw.config.get('wgPageParseReport').
  42 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  43   from certain IP ranges (e.g. private IPs).
  44 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  45   of the page being parsed.
  46
  47 === External library changes in 1.29 ===
  48
  49 ==== Upgraded external libraries ====
  50 * Updated QUnit from v1.22.0 to v1.23.1.
  51
  52 ==== New external libraries ====
  53
  54 ==== Removed and replaced external libraries ====
  55
  56 === Bug fixes in 1.29 ===
  57 * (T62604) Core parser functions returning a number now format the number according
  58   to the page content language, not wiki content language.
  59
  60 === Action API changes in 1.29 ===
  61 * Submitting sensitive authentication request parameters to action=clientlogin,
  62   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  63   in the query string is now an error. They should be submitted in the POST
  64   body instead.
  65 * The capture option for action=resetpassword has been removed
  66 * action=clearhasmsg now requires a POST.
  67 * (T47843) API errors and warnings may be requested in non-English languages
  68   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  69 * API error codes may have changed. Most notably, errors from modules using
  70   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  71 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  72   'errorformat'.
  73 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  74   'errors' subelements (as applicable) instead of 'message'.
  75 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  76 * action=move now reports errors when moving the talk page as an array under
  77   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  78   'talkmove-error-info'. The format for subpage move errors has also changed.
  79 * action=revisiondelete no longer includes a "rendered" property on warnings
  80   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  81   output.
  82 * action=rollback no longer returns a "messageHtml" property. Use
  83   errorformat=html if you're wanting HTML formatting of error messages.
  84 * action=upload now reports optional stash failures as an array under key
  85   'stasherrors' rather than a 'stashfailed' text string.
  86 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  87   no longer returns a 'message' on success.
  88 * Added action=validatepassword to validate passwords for the account creation
  89   and password change forms.
  90
  91 === Action API internal changes in 1.29 ===
  92 * New methods were added to ApiBase to handle errors and warnings using i18n
  93   keys. Methods for using hard-coded English messages were deprecated:
  94   * ApiBase::dieUsage() was deprecated
  95   * ApiBase::dieUsageMsg() was deprecated
  96   * ApiBase::dieUsageMsgOrDebug() was deprecated
  97   * ApiBase::getErrorFromStatus() was deprecated
  98   * ApiBase::parseMsg() was deprecated
  99   * ApiBase::setWarning() was deprecated
 100 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 101   result in a PHP fatal error.
 102 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 103   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 104   code for ApiBase::parseMsg() will no longer work.
 105 * UsageException is deprecated in favor of ApiUsageException. For the time
 106   being ApiUsageException is a subclass of UsageException to allow things that
 107   catch only UsageException to still function properly.
 108 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 109   ApiErrorFormatter_BackCompat, note that the result format has changed and
 110   various methods now take a module path rather than a module name.
 111 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 112   from the message key, and maps some message keys for backwards compatibility.
 113
 114 === Languages updated in 1.29 ===
 115
 116 MediaWiki supports over 350 languages. Many localisations are updated
 117 regularly. Below only new and removed languages are listed, as well as
 118 changes to languages because of Phabricator reports.
 119
 120 * Based as always on linguistic studies on intelligibility and language
 121   knowledge by geography, language fallbacks have been expanded. When a
 122   translation is missing in the user's preferred interface language, the
 123   corresponding translation for the fallback language will be used instead.
 124   English will only be used as last resort when there are no translations.
 125   Some configurations (such as date formats and gender namespaces) have also
 126   been updated when using the fallback language's configuration was inadequate.
 127   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 128   hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
 129
 130 ==== No fallback for Ukrainian ====
 131 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 132   language will now use the default fallback language: English. When a translation
 133   to Ukrainian is not available, an English string will be shown.
 134
 135 === Other changes in 1.29 ===
 136 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 137   SearchEngineFactory::getSearchEngineClass() instead.
 138 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 139   required as all sessions are stored in Object Cache now.
 140 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 141   Status return type is deprecated.
 142 * User::edits() (deprecated in 1.21) was removed.
 143 * Xml::escapeJsString() (deprecated in 1.21) was removed.
 144 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
 145   were removed.
 146 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
 147   were removed.
 148 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
 149   were removed.
 150 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
 151 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
 152 * WikiPage::getText() (deprecated in 1.21) was removed.
 153 * Article::fetchContent() (deprecated in 1.21) was removed.
 154 * User::getPassword() (deprecated in 1.27) was removed.
 155 * User::getTemporaryPassword() (deprecated in 1.27) was removed.
 156 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
 157 * FSRepo (deprecated in 1.19) was removed.
 158 * WebRequest::checkSessionCookie() (deprecated in 1.27) was removed. Use
 159 \MediaWiki\Session\SessionManager::singleton()->getPersistedSessionId() instead.
 160 * Class ImageGallery (deprecated in 1.22) was removed.
 161   Use ImageGalleryBase::factory instead.
 162 * Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class instead.
 163 * Hook UnknownAction (deprecated in 1.19) was actually deprecated (it will now emit warnings).
 164   Create a subclass of Action, and add it to $wgActions instead.
 165 * WikiRevision:getText() (deprecated since 1.21) is no longer marked deprecated.
 166
 167 == Compatibility ==
 168
 169 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 170 HHVM 3.6.5 or later.
 171
 172 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 173 support for them is somewhat less mature. There is experimental support for
 174 Oracle and Microsoft SQL Server.
 175
 176 The supported versions are:
 177
 178 * MySQL 5.0.3 or later
 179 * PostgreSQL 8.3 or later
 180 * SQLite 3.3.7 or later
 181 * Oracle 9.0.1 or later
 182 * Microsoft SQL Server 2005 (9.00.1399)
 183
 184 == Upgrading ==
 185
 186 1.29 has several database changes since 1.28, and will not work without schema
 187 updates. Note that due to changes to some very large tables like the revision
 188 table, the schema update may take quite long (minutes on a medium sized site,
 189 many hours on a large site).
 190
 191 If upgrading from before 1.11, and you are using a wiki as a commons
 192 repository, make sure that it is updated as well. Otherwise, errors may arise
 193 due to database schema changes.
 194
 195 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 196 new database fields are filled with data.
 197
 198 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 199 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 200 with MediaWiki 1.21.
 201
 202 Don't forget to always back up your database before upgrading!
 203
 204 See the file UPGRADE for more detailed upgrade instructions.
