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