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