Merge "mediawiki.api: Emit warning when deprecated callback parameters are used"
[lhc/web/wiklou.git] / RELEASE-NOTES-1.23
1 Security reminder: MediaWiki does not require PHP's register_globals. If you
2 have it on, turn it '''off''' if you can.

4 == MediaWiki 1.23 ==
5
6 THIS IS NOT A RELEASE YET
7
8 MediaWiki 1.23 is an alpha-quality branch and is not recommended for use in
9 production.
10
11 === Configuration changes in 1.23 ===
12 * When $wgJobRunRate is higher that zero, jobs are now executed via an
13 asynchronous HTTP request to a MediaWiki entry point. This may require
14 increasing the number of server worker threads.
15 * $wgDebugLogGroups values may be set to an associative array with a
16 'destination' key specifying the log destination. The array may also contain
17 a 'sample' key with a positive integer value N indicating that the log group
18 should be sampled by dispatching one in every N messages on average. The
19 sampling is random.
20 * In addition to the current exception log format, MediaWiki now serializes
21 exception metadata to JSON and logs it to the 'exception-json' log group.
22 This makes MediaWiki easier to integrate with log aggregation and analysis
23 tools.
24 * $wgSquidServersNoPurge now supports the use of Classless Inter-Domain
25 Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6
26 addresses that should be trusted to provide X-Forwarded-For headers.
27 * Preferences 'watchcreations', 'watchdefault', 'enotifwatchlistpages' ("Add
28 pages I create and files I upload to my watchlist", "Add pages and files I
29 edit to my watchlist", "Email me when a page or file on my watchlist is
30 changed") are now enabled by default. In addition new user accounts' personal
31 and talk pages are now watched by them by default.
32 * $wgLBFactoryConf: Class names have had underscores removed. The configuration
33 should be updated if LBFactory_Simple or LBFactory_Multi is configured.
34 * $wgPasswordSenderName has been removed and is no longer functional. To set a
35 custom mailer name, the system message 'emailsender' should be modified
36 (default: "{{SITENAME}}").
37 * $wgDBAhandler was removed as the only class using it was also removed
38 * The 'max threads' setting was removed from $wgDBservers.
39 * Support for AdminSettings.php has been completely removed. All configuration
40 belongs in LocalSettings.php.
41 * $wgSkipSkin, which has been replaceable by $wgSkipSkins since 2005 (r9249), is
42 now formally deprecated.
43 * Removed deprecated $wgDisabledActions as it is hardly used anywhere.
44
45 === New features in 1.23 ===
46 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
47 Compared to the browser cache, caching in Web Storage allows ResourceLoader
48 to be more granular about evicting stale modules from the cache while
49 retaining the ability to retrieve multiple modules in a single HTTP request.
50 This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
51 true. This feature is currently considered experimental and should only be
52 enabled with care.
53 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
54 and {{REVISIONTIMESTAMP:}} (with friends).
55 * Add "wgRelevantUserName" to mw.config containing the current
56 Skin::getRelevantUser value.
57 * (bug 56033) Add content model to the page information.
58 * Added Article::MissingArticleConditions hook to give extensions a chance to
59 hide their (unrelated) log entries.
60 * Added LonelyPagesQuery hook to let extensions modify the query used to
61 generate Special:LonelyPages.
62 * Added $wgOpenSearchDefaultLimit defining the default number of entries to show
63 on action=opensearch API call.
64 * For namespaces with $wgNamespaceProtection (including the MediaWiki
65 namespace), the "protect" tab will be shown only if there are restriction
66 levels available that would restrict editing beyond what
67 $wgNamespaceProtection already applies. The protection form will offer only
68 those protection levels.
69 * Added $wgAPIFormatModules, allowing extensions to add additional output
70 formatting modules for the API.
71 * (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add
72 custom CSS or JavaScript enabled only for registered users.
73 * (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist
74 now include a legend describing the symbols used in lists of changes.
75 * Improved the accessibility of the tabs in Special:Preferences.
76 * Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook:
77 it's called after everything is set up but before any major processing
78 happens.
79 * The jquery.client module now performs a component-wise version comparison in
80 its #test method when strings are used in the browser map: version '1.10' is
81 now correctly considered larger than '1.2'. Using numbers in the version map
82 is not affected.
83 * All API modules now support an assert parameter, which can either be
84 'user' or 'bot'. The API will throw an error if the user is not logged
85 in (user) or does not have the 'bot' userright (bot). Based off of the
86 AssertEdit extension by Steve Sanbeg.
87 * WikitextContent will now render redirects with the expected "redirect"
88 header, rather than as an ordered list. Code calling Article::viewRedirect
89 can probably be changed to no longer special-case redirects.
90 * [[Special:Diff]] was added, allowing users to create internal links to
91 revision comparison pages using syntax such as [[Special:Diff/12345]],
92 [[Special:Diff/12345/prev]] or [[Special:Diff/12345/98765]].
93 * New user accounts' personal and talk pages are now watched by them by default.
94 * Added SkinTemplateGetLanguageLink hook to allow changing the html of language
95 links.
96 * Added MessageCache::get hook as a new way to customize messages across
97 multiple sites.
98 * Added jquery.throttle-debounce ResourceLoader module to limit the number of
99 callbacks for frequently occurring events.
100 * Special:ProtectedPages shows now a table. The timestamp, the reason and
101 the protecting user is also shown.
102 * Added experimental support for using Microsoft SQL Server as the database
103 backend.
104 ** Added new Microsoft SQL Server-specific configuration variable
105 $wgDBWindowsAuthentication, which makes the web server authenticate against
106 the database server using Integrated Windows Authentication instead of
107 $wgDBuser/$wgDBpassword.
108 * HTMLForm 'select', 'selectandother', 'selectorother', 'multiselect', and
109 'radio' fields can now use message keys as labels via the 'options-messages'
110 parameter, which overrides the 'options' parameter.
111 * Admins can expire users users passwords manually, or on a schedule using the
112 $wgPasswordExpirationDays configuration setting.
113 * Add new hook SendWatchlistEmailNotification, this will be used to determine
114 whether to send a watchlist email notification.
115 * (bug 42026) Special:Contributions now includes an option to filter page
116 creations, similar to the topOnly option.
117
118 === Bug fixes in 1.23 ===
119 * (bug 41759) The "updated since last visit" markers (on history pages, recent
120 changes and watchlist) and the talk page message indicator are now correctly
121 updated when the user is viewing old revisions of pages, instead of always
122 acting as if the latest revision was being viewed.
123 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
124 when the email address is already confirmed. Also, consistently use
125 "confirmed", rather than "authenticated", when messaging whether or not the
126 user has confirmed an email address.
127 * (bug 56912) Show correct link color on cached result of Special:DeadendPages.
128 * Classes TitleListDependency and TitleDependency have been removed, as they
129 have been found unused in core and extensions for a long time.
130 * (bug 57098) SpecialPasswordReset now obeys returnto parameter
131 * (bug 37812) ResourceLoader will notice when a module's definition changes and
132 recompile it accordingly.
133 * (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds.
134 * (bug 58640) Fixed a compatibility issue with PCRE 8.34 that caused pages
135 to appear blank or with missing text.
136 * (bug 56931) Updated the plural rules to CLDR 24. They are in new format
137 which is detailed in UTS 35 Rev 33. The PHP parser and evaluator as well as
138 the JavaScript evaluator were updated to support the new format. Plural rules
139 for some languages have changed, most notably Russian. Affected software
140 messages have been updated and marked for review at translatewiki.net.
141 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
142 remaining page content.
143 * (bug 23542) imagelinks now stores both the redirect and target (as
144 templatelinks does).
145 * (bug 58167) The web installer no longer throws an exception when PHP is
146 compiled without support for MySQL yet with support for another DBMS.
147 * (bug 56199) Raw option of parser functions must now match complete word,
148 to take effect.
149 * (bug 60543) Special:PrefixIndex forgot stripprefix=1 for "Next page" link
150 * (bug 29762) Undoing an already-undone edit will now display an appropriate
151 message instead of leading the user to make a null edit.
152 * (bug 52659) mediawiki.notification: Notification area remained visible when
153 empty and thus was stealing pointer events from links on the page.
154 * (bug 26811) When a DBUnexpectedError occurs, DB server hostnames are now
155 hidden unless $wgShowExceptionDetails is true, and $wgShowDBErrorBacktrace
156 no longer applies in such cases.
157
158 === Web API changes in 1.23 ===
159 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
160 categories.
161 * action=query&meta=filerepoinfo now returns additional information for each
162 repo.
163 * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
164 MediaWiki 1.24.
165 * action=parse now has disabletoc flag to disable table of contents in output.
166 * (bug 25702) list=allcategories, list=allimages, list=alllinks, list=allpages,
167 list=deletedrevs and list=filearchive did not handle case-sensitivity
168 properly for all parameters.
169 * ApiQueryBase::titlePartToKey allows an extra parameter that indicates the
170 namespace in order to properly capitalize the title part.
171 * (bug 57874) action=feedcontributions no longer has one item more than limit.
172 * All API modules now support an assert parameter. See the new features section
173 for more details.
174 * Added prop=contributors to fetch the list of contributors to the page.
175 * The following API modules will now return entries where fields have been
176 revision-deleted: list=deletedrevs, list=filearchive, list=recentchanges,
177 list=watchlist. "hidden" indicators will be included, in the same style as is
178 already done for prop=revisions.
179 * The following API modules will now return the content of revision-deleted
180 fields, in addition to the "hidden" indicators, if the querying user has the
181 necessary rights: list=logevents, list=usercontribs, prop=imageinfo,
182 prop=revisions.
183 * The above modules, where applicable, will now return entries filtered by
184 revision-deleted fields if the querying user has the necessary rights. For
185 example, prop=revisions with rvuser or rvexcludeuser will no longer skip
186 revisions where the user was revision-deleted if the current user has the
187 deletedhistory right.
188 * The 'hideuser' right, used when blocking, is no longer necessary or
189 sufficient for seeing contributions with revision-deleted in
190 list=usercontribs.
191 * list=watchlist now uses the querying user's rights rather than the wlowner's
192 rights when checking whether wlprop=patrol is allowed.
193 * (bug 32151) ApiWatch now has pageset capabilities (titles/pageids/generators).
194 Title parameter is now deprecated.
195 * (bug 23005) Added action=revisiondelete.
196 * Added siprop=restrictions to API action=query&meta=siteinfo for querying
197 possible page restriction (protection) levels and types.
198 * Added prop 'limitreportdata' and 'limitreporthtml' to action=parse.
199 * (bug 58627) Provide language names on action=parse&prop=langlinks.
200 * Deprecated llurl= in favour of llprop=url for action=query&prop=langlinks.
201 * Added llprop=langname and llprop=autonym for action=query&prop=langlinks.
202 * prop=redirects is added, to return redirects to the pages in the query.
203 * list=allredirects is added, to list all redirects pointing to a namespace.
204 * (bug 42026) Added ucshow={new,!new,top,!top} to list=usercontribs.
205 Also added newonly to action=feedcontributions.
206 * (bug 42026) Deprecated uctoponly in favor of ucshow=top.
207
208 === Languages updated in 1.23 ===
209
210 MediaWiki supports over 350 languages. Many localisations are updated
211 regularly. Below only new and removed languages are listed, as well as
212 changes to languages because of Bugzilla reports.
213
214 * Support was added for Northern Luri (lrc).
215
216 === Other changes in 1.23 ===
217 * The rc_type field in the recentchanges table has been superseded by a new
218 rc_source field. The rc_source field is a string representation of the
219 change type where rc_type was a numeric constant. This field is not yet
220 queried but will be in a future point release of 1.22.
221 ** Utilize update.php to create and populate this new field. On larger wiki's
222 which do not wish to update recentchanges table in one large update please
223 review the sql and comments in maintenance/archives/patch-rc_source.sql.
224 ** The rc_type field of recentchanges will be deprecated in a future point
225 release.
226 * The global variable $wgArticle has been removed after a lengthy deprecation.
227 * The global functions addButton and insertTags (for mw.toolbar.addButton and
228 mw.toolbar.insertTags) now emits mw.log.warn when accessed.
229 * The ExpandTemplates extension has been moved into MediaWiki core.
230 * (bug 52812) Removed "Disable search suggestions" from Preference.
231 * (bug 52809) Removed "Disable browser page caching" from Preference.
232 * Three new modules intended for use by custom skins were added:
233 'skins.common.elements', 'skins.common.content', and 'skins.common.interface',
234 representing three levels of standard MediaWiki styling. Previously skin
235 creators wishing to use them had to refer to the file names of appropriate
236 files directly, which is now discouraged.
237 * The modules 'skins.vector' and 'skins.monobook' have been renamed to
238 'skins.vector.styles' and 'skins.monobook.styles', respectively,
239 and their definition was changed not to include the common*.css files;
240 the two skins now load the 'skins.common.interface' module instead.
241 * A page_links_updated field has been added to the page table.
242 * SpecialPage::getTitle has been deprecated in favor of
243 SpecialPage::getPageTitle.
244 * BREAKING CHANGE: Two potentially backwards-incompatible changes have been made
245 to the 'SpecialWatchlistQuery' hook's last parameter (array $values) to make
246 the hook more consistent with the 'SpecialRecentChangesQuery' one:
247 ** Several array keys have been renamed: hideMinor → hideminor,
248 hideBots → hidebots, hideAnons → hideanons, hideLiu → hideliu,
249 hidePatrolled → hidepatrolled, hideOwn → hidemyself.
250 ** The parameter value is now a FormOptions object, not a plain array (array
251 access operators should continue to work, as it implements the ArrayAccess
252 interface).
253 * Option to mark hooks as deprecated has been added.
254 * (bug 52811) Preference "Enable section editing via [edit] links" was removed.
255 * (bug 52813) Preference "Show table of contents (for pages with more than
256 3 headings)" was removed.
257 * (bug 52810) Preference "Justify paragraphs" was removed.
258 * OutputPage::showErrorPage raises a notice if arguments are incoherent.
259 * Thumbnails that keep failing to render in thumb.php will be rate-limited
260 againt further render attempts for 1 hour. $wgAttemptFailureEpoch can be
261 altered to reset all rate-limited thumbnails at once.
262 * (bug 56572) Builds of the OOjs and OOjs UI libraries are now available.
263 * mw.loader.go and mw.loader.version have been removed.
264 * (bug 52815) Preference "Enable simplified search bar (Vector skin only)"
265 was removed.
266 * A user_password_expires column has been added to the user table. The User
267 object expects this column to exist. Use update.php to create this new field.
268 * The jquery.delayedBind ResourceLoader module was deprecated in favor of the
269 jquery.throttle-debounce module. It will be removed in MediaWiki 1.24.
270 * mw.user.bucket has been deprecated.
271 * On Special:PrefixIndex, a table#mw-prefixindex-list-table was changed to
272 table.mw-prefixindex-list-table to avoid duplicate ids when the special page
273 is transcluded.
274 * (bug 62198) window.$j has been deprecated.

389 == Compatibility ==
390
391 MediaWiki 1.23 requires PHP 5.3.2 or later.
392
393 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
394 support for them is somewhat less mature. There is experimental support for
395 Oracle and Microsoft SQL Server.
396
397 The supported versions are:
398
399 * MySQL 5.0.2 or later
400 * PostgreSQL 8.3 or later
401 * SQLite 3.3.7 or later
402 * Oracle 9.0.1 or later
403 * Microsoft SQL Server 2005 (9.00.1399)
404
405 == Upgrading ==
406
407 1.23 has several database changes since 1.22, and will not work without schema
408 updates. Note that due to changes to some very large tables like the revision
409 table, the schema update may take quite long (minutes on a medium sized site,
410 many hours on a large site).
411
412 If upgrading from before 1.11, and you are using a wiki as a commons
413 repository, make sure that it is updated as well. Otherwise, errors may arise
414 due to database schema changes.
415
416 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
417 new database fields are filled with data.
418
419 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
420 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
421 with MediaWiki 1.21.
422
423 Don't forget to always back up your database before upgrading!
424
425 See the file UPGRADE for more detailed upgrade instructions.
426
427 For notes on 1.21.x and older releases, see HISTORY.
