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
  29 === New features in 1.29 ===
  30 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
  31   they move to a new IP address. This is disabled by default.
  32
  33 === External library changes in 1.29 ===
  34

  37

  41
  42 === Bug fixes in 1.29 ===
  43
  44 === Action API changes in 1.29 ===
  45 * Submitting sensitive authentication request parameters to action=clientlogin,
  46   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  47   in the query string is now an error. They should be submitted in the POST
  48   body instead.
  49 * The capture option for action=resetpassword has been removed
  50 * action=clearhasmsg now requires a POST.
  51 * (T47843) API errors and warnings may be requested in non-English languages
  52   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  53 * API error codes may have changed. Most notably, errors from modules using
  54   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  55 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  56   'errors' subelements (as applicable) instead of 'message'.
  57 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  58 * action=move now reports errors when moving the talk page as an array under
  59   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  60   'talkmove-error-info'. The format for subpage move errors has also changed.
  61 * action=revisiondelete no longer includes a "rendered" property on warnings
  62   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  63   output.
  64 * action=rollback no longer returns a "messageHtml" property. Use
  65   errorformat=html if you're wanting HTML formatting of error messages.
  66 * action=upload now reports optional stash failures as an array under key
  67   'stasherrors' rather than a 'stashfailed' text string.
  68 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  69   no longer returns a 'message' on success.
  70
  71 === Action API internal changes in 1.29 ===
  72 * New methods were added to ApiBase to handle errors and warnings using i18n
  73   keys. Methods for using hard-coded English messages were deprecated:
  74   * ApiBase::dieUsage() was deprecated
  75   * ApiBase::dieUsageMsg() was deprecated
  76   * ApiBase::dieUsageMsgOrDebug() was deprecated
  77   * ApiBase::getErrorFromStatus() was deprecated
  78   * ApiBase::parseMsg() was deprecated
  79   * ApiBase::setWarning() was deprecated
  80 * ApiBase::$messageMap is no longer public. Code attempting to access it will
  81   result in a PHP fatal error.
  82 * The $message parameter to the ApiCheckCanExecute hook should be set to an
  83   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
  84   code for ApiBase::parseMsg() will no longer work.
  85 * UsageException is deprecated in favor of ApiUsageException. For the time
  86   being ApiUsageException is a subclass of UsageException to allow things that
  87   catch only UsageException to still function properly.
  88 * If, for some strange reason, code was using an ApiErrorFormatter instead of
  89   ApiErrorFormatter_BackCompat, note that the result format has changed and
  90   various methods now take a module path rather than a module name.
  91 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
  92   from the message key, and maps some message keys for backwards compatibility.
  93
  94 === Languages updated in 1.29 ===
  95
  96 MediaWiki supports over 350 languages. Many localisations are updated
  97 regularly. Below only new and removed languages are listed, as well as
  98 changes to languages because of Phabricator reports.
  99
 100 ==== No fallback for Ukrainian ====
 101 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 102   language will now use the default fallback language: English. When a translation
 103   to Ukrainian is not available, an English string will be shown.
 104
 105 === Other changes in 1.29 ===
 106 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 107   SearchEngineFactory::getSearchEngineClass() instead.
 108 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 109   required as all sessions are stored in Object Cache now.
 110 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 111   Status return type is deprecated.
 112 * User::edits() (deprecated in 1.21) was removed.
 113 * Xml::escapeJsString() (deprecated in 1.21) was removed.
 114 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
 115   were removed.
 116 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
 117   were removed.
 118 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
 119   were removed.
 120 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
 121 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
 122 * WikiPage::getText() (deprecated in 1.21) was removed.
 123 * Article::fetchContent() (deprecated in 1.21) was removed.
 124
 125 == Compatibility ==
 126
 127 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 128 HHVM 3.6.5 or later.
 129
 130 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 131 support for them is somewhat less mature. There is experimental support for
 132 Oracle and Microsoft SQL Server.
 133
 134 The supported versions are:
 135
 136 * MySQL 5.0.3 or later
 137 * PostgreSQL 8.3 or later
 138 * SQLite 3.3.7 or later
 139 * Oracle 9.0.1 or later
 140 * Microsoft SQL Server 2005 (9.00.1399)
 141
 142 == Upgrading ==
 143
 144 1.29 has several database changes since 1.28, and will not work without schema
 145 updates. Note that due to changes to some very large tables like the revision
 146 table, the schema update may take quite long (minutes on a medium sized site,
 147 many hours on a large site).
 148
 149 If upgrading from before 1.11, and you are using a wiki as a commons
 150 repository, make sure that it is updated as well. Otherwise, errors may arise
 151 due to database schema changes.
 152
 153 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 154 new database fields are filled with data.
 155
 156 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 157 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 158 with MediaWiki 1.21.
 159
 160 Don't forget to always back up your database before upgrading!
 161
 162 See the file UPGRADE for more detailed upgrade instructions.
