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 * A temporary feature flag, $wgDisableUserGroupExpiry, is provided to disable
  32   new features that rely on the schema changes to the user_groups table. This
  33   feature flag will likely be removed before 1.29 is released.
  34 * (T158474) "Unknown user" has been added to $wgReservedUsernames.
  35 * (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
  36 * $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
  37   added to $wgExtraLanguageCodes instead.
  38
  39 === New features in 1.29 ===
  40 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
  41   if they move to a new IP address. This is disabled by default.
  42 * Added ILocalizedException interface to standardize the use of localized
  43   exceptions, largely so the API can handle them more sensibly.
  44 * Blocks created automatically by MediaWiki, such as for configured proxies or
  45   dnsbls, are now indicated as such and use a new i18n message when displayed.
  46 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  47   downloading the XML dump during a transwiki import in seconds.
  48 * Parser limit report is now available in machine-readable format to JavaScript
  49   via mw.config.get('wgPageParseReport').
  50 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  51   from certain IP ranges (e.g. private IPs).
  52 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  53   of the page being parsed.
  54 * HTML5 form validation attributes will no longer be suppressed. Originally
  55   browsers had poor support for them, but modern browsers handle them fine.
  56   This might affect some forms that used them and only worked because the
  57   attributes were not actually being set.
  58 * Expiry times can now be specified when users are added to user groups.
  59 * Completely new user interface for the RecentChanges page, which
  60   structures filters into user-friendly groups.  This has corresponding
  61   changes to how filters are registered by core and extensions.
  62

  80
  81 === Bug fixes in 1.29 ===
  82 * (T62604) Core parser functions returning a number now format the number according
  83   to the page content language, not wiki content language.
  84 * (T27187) Search suggestions based on jquery.suggestions will now correctly only
  85   highlight prefix matches in the results.
  86 * (T157035) "new mw.Uri()" was ignoring options when using default URI.
  87 * Special:Allpages can no longer be filtered by redirect in miser mode.
  88 * (T160519) CACHE_ANYTHING will not be CACHE_ACCEL if no accelerator is installed.
  89
  90 === Action API changes in 1.29 ===
  91 * Submitting sensitive authentication request parameters to action=login,
  92   action=clientlogin, action=createaccount, action=linkaccount, and
  93   action=changeauthenticationdata in the query string is now an error. They
  94   should be submitted in the POST body instead.
  95 * The capture option for action=resetpassword has been removed
  96 * action=clearhasmsg now requires a POST.
  97 * (T47843) API errors and warnings may be requested in non-English languages
  98   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  99 * API error codes may have changed. Most notably, errors from modules using
 100   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
 101 * ApiPageSet-using modules will report the 'invalidreason' using the specified
 102   'errorformat'.
 103 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
 104   'errors' subelements (as applicable) instead of 'message'.
 105 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
 106 * action=move now reports errors when moving the talk page as an array under
 107   key 'talkmove-errors', rather than using 'talkmove-error-code' and
 108   'talkmove-error-info'. The format for subpage move errors has also changed.
 109 * action=revisiondelete no longer includes a "rendered" property on warnings
 110   and errors for each item. Use errorformat=wikitext if you're wanting parsed
 111   output.
 112 * action=rollback no longer returns a "messageHtml" property. Use
 113   errorformat=html if you're wanting HTML formatting of error messages.
 114 * action=upload now reports optional stash failures as an array under key
 115   'stasherrors' rather than a 'stashfailed' text string.
 116 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
 117   no longer returns a 'message' on success.
 118 * Added action=validatepassword to validate passwords for the account creation
 119   and password change forms.
 120 * action=purge now requires a POST.
 121 * There is a new `languagevariants` siprop for action=query&meta=siteinfo,
 122   which returns a list of languages with active LanguageConverter instances.
 123 * action=query&query=allpages will no longer filter redirects using a database
 124   query in miser mode. This may result in less results being returned than were
 125   requested.
 126
 127 === Action API internal changes in 1.29 ===
 128 * New methods were added to ApiBase to handle errors and warnings using i18n
 129   keys. Methods for using hard-coded English messages were deprecated:
 130   * ApiBase::dieUsage() was deprecated
 131   * ApiBase::dieUsageMsg() was deprecated
 132   * ApiBase::dieUsageMsgOrDebug() was deprecated
 133   * ApiBase::getErrorFromStatus() was deprecated
 134   * ApiBase::parseMsg() was deprecated
 135   * ApiBase::setWarning() was deprecated
 136 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 137   result in a PHP fatal error.
 138 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 139   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 140   code for ApiBase::parseMsg() will no longer work.
 141 * UsageException is deprecated in favor of ApiUsageException. For the time
 142   being ApiUsageException is a subclass of UsageException to allow things that
 143   catch only UsageException to still function properly.
 144 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 145   ApiErrorFormatter_BackCompat, note that the result format has changed and
 146   various methods now take a module path rather than a module name.
 147 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 148   from the message key, and maps some message keys for backwards compatibility.
 149
 150 === Languages updated in 1.29 ===
 151
 152 MediaWiki supports over 350 languages. Many localisations are updated
 153 regularly. Below only new and removed languages are listed, as well as
 154 changes to languages because of Phabricator reports.
 155
 156 * Based as always on linguistic studies on intelligibility and language
 157   knowledge by geography, language fallbacks have been expanded. When a
 158   translation is missing in the user's preferred interface language, the
 159   corresponding translation for the fallback language will be used instead.
 160   English will only be used as last resort when there are no translations.
 161   Some configurations (such as date formats and gender namespaces) have also
 162   been updated when using the fallback language's configuration was inadequate.
 163   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 164   ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
 165   sh → bs, sr-el, hr.
 166 * (T137376) New language support: Atikamekw (atj).
 167 * (T155957) Talk Namespaces for Javanese language (jv) have been updated.
 168
 169 ==== No fallback for Ukrainian ====
 170 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 171   language will now use the default fallback language: English. When a translation
 172   to Ukrainian is not available, an English string will be shown.
 173
 174 === Other changes in 1.29 ===
 175 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 176   SearchEngineFactory::getSearchEngineClass() instead.
 177 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 178   required as all sessions are stored in Object Cache now.
 179 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 180   Status return type is deprecated.
 181 * User::edits() (deprecated in 1.21) was removed.

 212   and outdated lists of errors/warnings returned by the API, are now deprecated.
 213 * wiki.phtml entry point was removed.  Refer to index.php instead. If you want "wiki.phtml"
 214   URLs to continue to work, set up redirects. In Apache, this can be done by enabling
 215   mod_rewrite and adding the following rules to your configuration:
 216
 217     RewriteEngine On
 218     RewriteBase /
 219     RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]

 238 * Article::doEdit() and WikiPage::doEdit() (deprecated in 1.21) were removed.
 239 * Parser::replaceUnusualEscapes() (deprecated in 1.24) was removed.
 240 * Article::doEditContent() was marked as deprecated, to be removed in 1.30
 241   or later.
 242 * ContentHandler::runLegacyHooks() was removed.
 243 * refreshLinks.php now can be limited to a particular category with --category=...
 244   or a tracking category with --tracking-category=...
 245 * User-like objects that are passed to SpecialUserRights and its subclasses are
 246   now required to have a getGroupMemberships() method. See UserRightsProxy for
 247   an example.
 248 * User::$mGroups (instance variable) was marked private. Use User::getGroups()
 249   instead.
 250 * User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
 251   User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
 252   Use equivalent methods on the UserGroupMembership class.
 253 * Maintenance scripts and tests that call User::addGroup() must now ensure that
 254   User objects have been added to the database prior to calling addGroup().
 255 * Protected function UsersPager::getGroups() was removed, and protected function
 256   UsersPager::buildGroupLink() was changed from a static to an instance method.
 257 * The third parameter ($cache) to the UsersPagerDoBatchLookups hook was changed;
 258   see docs/hooks.txt.
 259 * User::crypt() (deprecated in 1.24) was removed.
 260 * User::comparePasswords() (deprecated in 1.24) was removed.
 261 * ArchivedFile::getUserText() (deprecated in 1.23) was removed.
 262 * HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
 263 * BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
 264   and subclasses.  It should only break if you call buildMainQueryConds
 265   (changed to buildQuery with new signature) or doMainQuery (new
 266   signature).  Subclasses are likely to call at least doMainQuery
 267   (possibly both), but other classes might too, because they were
 268   public.
 269   Also, some related hooks were deprecated, but this is not yet a
 270   breaking change.
 271 * Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
 272 * The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
 273 * WikiRevision::$fileIsTemp was deprecated.
 274 * WikiRevision::$importer was deprecated.
 275 * WikiRevision::$user was deprecated.
 276 * Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
 277   WikiPage::PURGE_* constants are deprecated, and the functions will always
 278   return false. They were a hack for an issue that has since been fixed.
 279 * Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
 280   'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
 281   if you don't actually care about checkboxes and just want to add some HTML
 282   to the page.
 283 * Selflinks are now rendered as href-less <a> tags with the class mw-selflink
 284   rather than <strong> tags. The old class name, "selflink", was deprecated
 285   and will be removed in a future release. (T160480)
 286 * (T156184) $wgRawHtml will no longer apply to internationalization messages.
 287 * Browser support for non-ES5 JavaScript browsers, including Android 2,
 288   Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
 289
 290 == Compatibility ==
 291
 292 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 293 HHVM 3.6.5 or later.
 294
 295 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 296 support for them is somewhat less mature. There is experimental support for
 297 Oracle and Microsoft SQL Server.
 298
 299 The supported versions are:
 300
 301 * MySQL 5.0.3 or later
 302 * PostgreSQL 8.3 or later
 303 * SQLite 3.3.7 or later
 304 * Oracle 9.0.1 or later
 305 * Microsoft SQL Server 2005 (9.00.1399)
 306
 307 == Upgrading ==
 308
 309 1.29 has several database changes since 1.28, and will not work without schema
 310 updates. Note that due to changes to some very large tables like the revision
 311 table, the schema update may take quite long (minutes on a medium sized site,
 312 many hours on a large site).
 313
 314 If upgrading from before 1.11, and you are using a wiki as a commons
 315 repository, make sure that it is updated as well. Otherwise, errors may arise
 316 due to database schema changes.
 317
 318 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 319 new database fields are filled with data.
 320
 321 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 322 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 323 with MediaWiki 1.21.
 324
 325 Don't forget to always back up your database before upgrading!
 326
 327 See the file UPGRADE for more detailed upgrade instructions.
 328
 329 For notes on 1.28.x and older releases, see HISTORY.
 330
