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
  32 === New features in 1.29 ===
  33 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
  34   if they move to a new IP address. This is disabled by default.
  35 * Added ILocalizedException interface to standardize the use of localized
  36   exceptions, largely so the API can handle them more sensibly.
  37 * Blocks created automatically by MediaWiki, such as for configured proxies or
  38   dnsbls, are now indicated as such and use a new i18n message when displayed.
  39 * Added new $wgHTTPImportTimeout setting. Sets timeout for
  40   downloading the XML dump during a transwiki import in seconds.
  41 * Parser limit report is now available in machine-readable format to JavaScript
  42   via mw.config.get('wgPageParseReport').
  43 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
  44   from certain IP ranges (e.g. private IPs).
  45 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
  46   of the page being parsed.
  47 * HTML5 form validation attributes will no longer be suppressed. Originally
  48   browsers had poor support for them, but modern browsers handle them fine.
  49   This might affect some forms that used them and only worked because the
  50   attributes were not actually being set.
  51
  52 === External library changes in 1.29 ===
  53
  54 ==== Upgraded external libraries ====
  55 * Updated QUnit from v1.22.0 to v1.23.1.
  56
  57 ==== New external libraries ====
  58
  59 ==== Removed and replaced external libraries ====
  60
  61 === Bug fixes in 1.29 ===
  62 * (T62604) Core parser functions returning a number now format the number according
  63   to the page content language, not wiki content language.
  64
  65 === Action API changes in 1.29 ===
  66 * Submitting sensitive authentication request parameters to action=clientlogin,
  67   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  68   in the query string is now an error. They should be submitted in the POST
  69   body instead.
  70 * The capture option for action=resetpassword has been removed
  71 * action=clearhasmsg now requires a POST.
  72 * (T47843) API errors and warnings may be requested in non-English languages
  73   using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
  74 * API error codes may have changed. Most notably, errors from modules using
  75   parameter prefixes (e.g. all query submodules) will no longer be prefixed.
  76 * ApiPageSet-using modules will report the 'invalidreason' using the specified
  77   'errorformat'.
  78 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
  79   'errors' subelements (as applicable) instead of 'message'.
  80 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
  81 * action=move now reports errors when moving the talk page as an array under
  82   key 'talkmove-errors', rather than using 'talkmove-error-code' and
  83   'talkmove-error-info'. The format for subpage move errors has also changed.
  84 * action=revisiondelete no longer includes a "rendered" property on warnings
  85   and errors for each item. Use errorformat=wikitext if you're wanting parsed
  86   output.
  87 * action=rollback no longer returns a "messageHtml" property. Use
  88   errorformat=html if you're wanting HTML formatting of error messages.
  89 * action=upload now reports optional stash failures as an array under key
  90   'stasherrors' rather than a 'stashfailed' text string.
  91 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
  92   no longer returns a 'message' on success.
  93 * Added action=validatepassword to validate passwords for the account creation
  94   and password change forms.
  95
  96 === Action API internal changes in 1.29 ===
  97 * New methods were added to ApiBase to handle errors and warnings using i18n
  98   keys. Methods for using hard-coded English messages were deprecated:
  99   * ApiBase::dieUsage() was deprecated
 100   * ApiBase::dieUsageMsg() was deprecated
 101   * ApiBase::dieUsageMsgOrDebug() was deprecated
 102   * ApiBase::getErrorFromStatus() was deprecated
 103   * ApiBase::parseMsg() was deprecated
 104   * ApiBase::setWarning() was deprecated
 105 * ApiBase::$messageMap is no longer public. Code attempting to access it will
 106   result in a PHP fatal error.
 107 * The $message parameter to the ApiCheckCanExecute hook should be set to an
 108   ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
 109   code for ApiBase::parseMsg() will no longer work.
 110 * UsageException is deprecated in favor of ApiUsageException. For the time
 111   being ApiUsageException is a subclass of UsageException to allow things that
 112   catch only UsageException to still function properly.
 113 * If, for some strange reason, code was using an ApiErrorFormatter instead of
 114   ApiErrorFormatter_BackCompat, note that the result format has changed and
 115   various methods now take a module path rather than a module name.
 116 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
 117   from the message key, and maps some message keys for backwards compatibility.
 118
 119 === Languages updated in 1.29 ===
 120
 121 MediaWiki supports over 350 languages. Many localisations are updated
 122 regularly. Below only new and removed languages are listed, as well as
 123 changes to languages because of Phabricator reports.
 124
 125 * Based as always on linguistic studies on intelligibility and language
 126   knowledge by geography, language fallbacks have been expanded. When a
 127   translation is missing in the user's preferred interface language, the
 128   corresponding translation for the fallback language will be used instead.
 129   English will only be used as last resort when there are no translations.
 130   Some configurations (such as date formats and gender namespaces) have also
 131   been updated when using the fallback language's configuration was inadequate.
 132   The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
 133   hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
 134
 135 ==== No fallback for Ukrainian ====
 136 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
 137   language will now use the default fallback language: English. When a translation
 138   to Ukrainian is not available, an English string will be shown.
 139
 140 === Other changes in 1.29 ===
 141 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
 142   SearchEngineFactory::getSearchEngineClass() instead.
 143 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
 144   required as all sessions are stored in Object Cache now.
 145 * MWHttpRequest::execute() should be considered to return a StatusValue; the
 146   Status return type is deprecated.

 167   Use ImageGalleryBase::factory instead.
 168 * Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class instead.

 179 * wiki.phtml entry point was removed.  Refer to index.php instead. If you want "wiki.phtml"
 180   URLs to continue to work, set up redirects. In Apache, this can be done by enabling
 181   mod_rewrite and adding the following rules to your configuration:
 182
 183     RewriteEngine On
 184     RewriteBase /
 185     RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]

 209
 210 == Compatibility ==
 211
 212 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
 213 HHVM 3.6.5 or later.
 214
 215 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 216 support for them is somewhat less mature. There is experimental support for
 217 Oracle and Microsoft SQL Server.
 218
 219 The supported versions are:
 220
 221 * MySQL 5.0.3 or later
 222 * PostgreSQL 8.3 or later
 223 * SQLite 3.3.7 or later
 224 * Oracle 9.0.1 or later
 225 * Microsoft SQL Server 2005 (9.00.1399)
 226
 227 == Upgrading ==
 228
 229 1.29 has several database changes since 1.28, and will not work without schema
 230 updates. Note that due to changes to some very large tables like the revision
 231 table, the schema update may take quite long (minutes on a medium sized site,
 232 many hours on a large site).
 233
 234 If upgrading from before 1.11, and you are using a wiki as a commons
 235 repository, make sure that it is updated as well. Otherwise, errors may arise
 236 due to database schema changes.
 237
 238 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 239 new database fields are filled with data.
 240
 241 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 242 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 243 with MediaWiki 1.21.
 244
 245 Don't forget to always back up your database before upgrading!
 246
 247 See the file UPGRADE for more detailed upgrade instructions.
 248
 249 For notes on 1.28.x and older releases, see HISTORY.
