== MediaWiki 1.31 ==
|
|
|
|
|
|
|
|
|
|
THIS IS NOT A RELEASE YET
|
|
|
|
|
|
|
|
|
|
MediaWiki 1.31 is an alpha-quality branch and is not recommended for use in
|
|
|
|
|
production.
|
|
|
|
|
|
|
|
|
|
=== Configuration changes in 1.31 ===
|
2017-10-11 23:02:05 +00:00
|
|
|
* $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
|
|
|
|
|
a future version. The API is now considered to be stable, secure and
|
|
|
|
|
essential.
|
2017-10-05 18:25:51 +00:00
|
|
|
* $wgUsejQueryThree was removed, as it is now the default. This was documented as a
|
|
|
|
|
temporary variable during the migration period, deprecated since 1.29.
|
2017-05-22 18:12:26 +00:00
|
|
|
* $wgLogoHD has been updated to support svg images and uses $wgLogo where
|
|
|
|
|
possible for fallback images such as png.
|
2017-10-14 03:20:10 +00:00
|
|
|
* (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does
|
|
|
|
|
not have the right to mark things patrolled.
|
2017-10-25 19:26:53 +00:00
|
|
|
* Wikis that contain imported revisions or CentralAuth global blocks should run
|
|
|
|
|
maintenance/cleanupUsersWithNoId.php.
|
2017-11-30 23:19:10 +00:00
|
|
|
* $wgResourceLoaderMinifierStatementsOnOwnLine and $wgResourceLoaderMinifierMaxLineLength
|
|
|
|
|
were removed (deprecated since 1.27).
|
2017-12-23 17:35:59 +00:00
|
|
|
* (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that are not
|
|
|
|
|
using the latest version of the Referrer Policy specification.
|
2018-01-20 02:36:30 +00:00
|
|
|
* $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a first step of
|
|
|
|
|
migration to human-readable section IDs that will later result in 'html5' being the
|
|
|
|
|
default mode.

=== New features in 1.31 ===
|
Database: Support parenthesized JOINs
SQL supports parentheses for grouping in the FROM clause.[1] This is
useful when you want to left-join against a join of other tables.
For example, say you have tables 'a', 'b', and 'c'. You want all rows
from 'a', along with rows from 'b' + 'c' only where both of those
exist.
SELECT * FROM a LEFT JOIN b ON (a_b = b_id) JOIN c ON (b_c = c_id)
doesn't work, it'll only give you the rows where 'c' exists.
SELECT * FROM a LEFT JOIN b ON (a_b = b_id) LEFT JOIN c ON (b_c = c_id)
doesn't work either, it'll give you rows from 'b' without a
corresponding row in 'c'. What you need to do is
SELECT * FROM a LEFT JOIN (b JOIN c ON (b_c = c_id)) ON (a_b = b_id)
This patch implements this by extending the syntax for the $table
parameter to IDatabase::select(). When passing an array of tables, if a
value in the array is itself an array that is interpreted as a request
for a parenthesized join. To produce the example above, you'd do
something like
$db->select(
[ 'a', 'nest' => [ 'b', 'c' ] ],
'*',
[],
__METHOD__,
[],
[
'c' => [ 'JOIN', 'b_c = c_id ],
'nest' => [ 'LEFT JOIN', 'a_b = b_id' ],
]
);
[1]: In standards as far back as SQL-1992 (I couldn't find an earlier
version), and it seems to be supported by at least MySQL 5.6, MariaDB
10.1.28, PostgreSQL 9.3, PostgreSQL 10.0, Oracle 11g R2, SQLite 3.20.1,
and MSSQL 2014 (from local testing and sqlfiddle.com).

* Wikimedia\Rdbms\IDatabase->select() and similar methods now support

|
joins with parentheses for grouping.
|
2017-09-28 18:42:32 +00:00
|
|
|
* As a first pass in standardizing dialog boxes across the MediaWiki product,
|
2017-11-15 16:44:53 +00:00
|
|
|
Html class now provides helper methods for messageBox, successBox, errorBox and
|
|

warningBox generation.

|
|

|
|
|
|
|

|
|
|
|
|
* (T20209) Linker (used on history pages, log pages, and so on) will display
|
|
|
|
|
usernames formed like "iw>Example" as interwiki links, as if by wikitext like
|
|
|
|
|
[[iw:User:Example|iw>Example]].
|
|
|
|
|
* (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
|
|
|
|
|
users during an import.

|
|
|
|
|
the ParserOutput::getText() post-cache transformations.
|
2017-12-18 14:14:38 +00:00
|
|
|
* Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
|
|
|
|
|
initial page text for file uploads.
|
2018-01-25 04:58:06 +00:00
|
|
|
* (T181651) The info page for File pages now displays the file's base-16 SHA1
|
2018-01-18 07:16:09 +00:00

The corresponding configuration variable ($wgResourceLoaderMinifierStatementsOnOwnLine)

has been deprecated since 1.27 and was removed as well.
|
2018-01-11 22:59:47 +00:00
|
|

|
|
|
|
|

* QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
|
|
|
|
|
Setting template variables by reference allowed violating the principle of data being
|
|
|
|
|
immutable once added to the skin template. In practice, this method was not being
|
|
|
|
|
used for that. Rather, setRef() existed as memory optimisation for PHP 4.
|
2017-12-22 18:32:49 +00:00
|
|
|
* Passing false to ParserOptions::setWrapOutputClass() is deprecated. Use the

|

|
|
|

ParserOptions::setWrapOutputClass() can no longer be added to the parser
|
|
|
|
|
cache.

MediaWiki 1.31 requires PHP 5.5.9 or later. Although HHVM 3.18.5 or later is supported,
|
|
|
|
|
it is generally advised to use PHP 5.5.9 or later for long term support.

|
|
|
|
|
MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
|
|
|
|
|
but support for them is somewhat less mature. There is experimental support for
|
|
|
|
|
Oracle and Microsoft SQL Server.
|
|
|
|
|
|
|
|
|
|
The supported versions are:
|
|
|
|
|
|
|
|
|
|
* MySQL 5.0.3 or later
|
|
|
|
|
* PostgreSQL 8.3 or later
|
|
|
|
|
* SQLite 3.3.7 or later
|
|
|
|
|
* Oracle 9.0.1 or later
|
|
|
|
|
* Microsoft SQL Server 2005 (9.00.1399)
|
|

== Upgrading ==
|
|
|
|
|
1.31 has several database changes since 1.30, and will not work without schema
|
|
|
|
|
updates. Note that due to changes to some very large tables like the revision
|
|
|
|
|
table, the schema update may take quite long (minutes on a medium sized site,
|
|
|
|
|
many hours on a large site).
|
|
|
|
|
|
|
|
|
|
Don't forget to always back up your database before upgrading!
|
|
|
|
|
|
|
|
|
|
See the file UPGRADE for more detailed upgrade instructions, including
|
|
|
|
|
important information when upgrading from versions prior to 1.11.
|
|
|
|
|
|
|
|
|
|
For notes on 1.30.x and older releases, see HISTORY.
