+The ContentHandler facility adds support for arbitrary content types on wiki pages, instead of relying on wikitext
+for everything. It was introduced in MediaWiki 1.21.
+
+Each kind of content ("content model") supported by MediaWiki is identified by unique name. The content model determines
+how a page's content is rendered, compared, stored, edited, and so on.
+
+Built-in content types are:
+
+* wikitext - wikitext, as usual
+* javascript - user provided javascript code
+* json - simple implementation for use by extensions, etc.
+* css - user provided css code
+* text - plain text
+
+In PHP, use the corresponding CONTENT_MODEL_XXX constant.
+
+A page's content model is available using the Title::getContentModel() method. A page's default model is determined by
+ContentHandler::getDefaultModelFor($title) as follows:
+
+* The global setting $wgNamespaceContentModels specifies a content model for the given namespace.
+* The hook ContentHandlerDefaultModelFor may be used to override the page's default model.
+* Pages in NS_MEDIAWIKI and NS_USER default to the CSS or JavaScript model if they end in .css or .js, respectively.
+  Pages in NS_MEDIAWIKI default to the wikitext model otherwise.
+* Otherwise, the wikitext model is used.
+
+Note that is currently no mechanism to convert a page from one content model to another, and there is no guarantee that
+revisions of a page will all have the same content model. Use Revision::getContentModel() to find it.
+
+
+== Architecture ==
+
+Two class hierarchies are used to provide the functionality associated with the different content models:
+
+* Content interface (and AbstractContent base class) define functionality that acts on the concrete content of a page, and
+* ContentHandler base class provides functionality specific to a content model, but not acting on concrete content.
+
+The most important function of ContentHandler is to act as a factory for the appropriate implementation of Content. These
+Content objects are to be used by MediaWiki everywhere, instead of passing page content around as text. All manipulation
+and analysis of page content must be done via the appropriate methods of the Content object.
+
+For each content model, a subclass of ContentHandler has to be registered with $wgContentHandlers. The ContentHandler
+object for a given content model can be obtained using ContentHandler::getForModelID( $id ). Also Title, WikiPage and
+Revision now have getContentHandler() methods for convenience.
+
+ContentHandler objects are singletons that provide functionality specific to the content type, but not directly acting
+on the content of some page. ContentHandler::makeEmptyContent() and ContentHandler::unserializeContent() can be used to
+create a Content object of the appropriate type. However, it is recommended to instead use WikiPage::getContent() resp.
+Revision::getContent() to get a page's content as a Content object. These two methods should be the ONLY way in which
+page content is accessed.
+
+Another important function of ContentHandler objects is to define custom action handlers for a content model, see
+ContentHandler::getActionOverrides(). This is similar to what WikiPage::getActionOverrides() was already doing.
+
+
+== Serialization ==
+
+With the ContentHandler facility, page content no longer has to be text based. Objects implementing the Content interface
+are used to represent and handle the content internally. For storage and data exchange, each content model supports
+at least one serialization format via ContentHandler::serializeContent( $content ). The list of supported formats for
+a given content model can be accessed using ContentHandler::getSupportedFormats().
+
+Content serialization formats are identified using MIME type like strings. The following formats are built in:
+
+* text/x-wiki - wikitext
+* text/javascript - for js pages
+* text/css - for css pages
+* text/plain - for future use, e.g. with plain text messages.
+* text/html - for future use, e.g. with plain html messages.
+* application/vnd.php.serialized - for future use with the api and for extensions
+* application/json - for future use with the api, and for use by extensions
+* application/xml - for future use with the api, and for use by extensions
+
+In PHP, use the corresponding CONTENT_FORMAT_XXX constant.
+
+Note that when using the API to access page content, especially action=edit, action=parse and action=query&prop=revisions,
+the model and format of the content should always be handled explicitly. Without that information, interpretation of
+the provided content is not reliable. The same applies to XML dumps generated via maintenance/dumpBackup.php or
+Special:Export.
+
+Also note that the API will provide encapsulated, serialized content - so if the API was called with format=json, and
+contentformat is also json (or rather, application/json), the page content is represented as a string containing an
+escaped json structure. Extensions that use JSON to serialize some types of page content may provide specialized API
+modules that allow access to that content in a more natural form.
+
+
+== Compatibility ==
+
+The ContentHandler facility is introduced in a way that should allow all existing code to keep functioning at least
+for pages that contain wikitext or other text based content. However, a number of functions and hooks have been
+deprecated in favor of new versions that are aware of the page's content model, and will now generate warnings when
+used.
+
+Most importantly, the following functions have been deprecated:
+
+* Revisions::getText() is deprecated in favor Revisions::getContent()
+* WikiPage::getText() is deprecated in favor WikiPage::getContent()
+
+Also, the old Article::getContent() (which returns text) is superceded by Article::getContentObject(). However, both
+methods should be avoided since they do not provide clean access to the page's actual content. For instance, they may
+return a system message for non-existing pages. Use WikiPage::getContent() instead.
+
+Code that relies on a textual representation of the page content should eventually be rewritten. However,
+ContentHandler::getContentText() provides a stop-gap that can be used to get text for a page. Its behavior is controlled
+by $wgContentHandlerTextFallback; per default it will return the text for text based content, and null for any other
+content.
+
+For rendering page content, Content::getParserOutput() should be used instead of accessing the parser directly.
+ContentHandler::makeParserOptions() can be used to construct appropriate options.
+
+
+Besides some functions, some hooks have also been replaced by new versions (see hooks.txt for details).
+These hooks will now trigger a warning when used:
+
+* ArticleAfterFetchContent was replaced by ArticleAfterFetchContentObject
+* ArticleInsertComplete was replaced by PageContentInsertComplete
+* ArticleSave was replaced by PageContentSave
+* ArticleSaveComplete was replaced by PageContentSaveComplete
+* ArticleViewCustom was replaced by ArticleContentViewCustom (also consider a custom implementation of the view action)
+* EditFilterMerged was replaced by EditFilterMergedContent
+* EditPageGetDiffText was replaced by EditPageGetDiffContent
+* EditPageGetPreviewText was replaced by EditPageGetPreviewContent
+* ShowRawCssJs was deprecated in favor of custom rendering implemented in the respective ContentHandler object.
+
+
+== Database Storage ==
+
+Page content is stored in the database using the same mechanism as before. Non-text content is serialized first. The
+appropriate serialization and deserialization is handled by the Revision class.
+
+Each revision's content model and serialization format is stored in the revision table (resp. in the archive table, if
+the revision was deleted). The page's (current) content model (that is, the content model of the latest revision) is also
+stored in the page table.
+
+Note however that the content model and format is only stored if it differs from the page's default, as determined by
+ContentHandler::getDefaultModelFor( $title ). The default values are represented as NULL in the database, to preserve
+space.
+
+Storage of content model and format can be disabled altogether by setting $wgContentHandlerUseDB = false. In that case,
+the page's default model (and the model's default format) will be used everywhere. Attempts to store a revision of a page
+using a model or format different from the default will result in an error.
+
+
+== Globals ==
+
+There are some new globals that can be used to control the behavior of the ContentHandler facility:
+
+* $wgContentHandlers associates content model IDs with the names of the appropriate ContentHandler subclasses
+  or callbacks that create an instance of the appropriate ContentHandler subclass.
+
+* $wgNamespaceContentModels maps namespace IDs to a content model that should be the default for that namespace.
+
+* $wgContentHandlerUseDB determines whether each revision's content model should be stored in the database.
+  Defaults is true.
+
+* $wgContentHandlerTextFallback determines how the compatibility method ContentHandler::getContentText() will behave for
+  non-text content:
+    'ignore'     causes null to be returned for non-text content (default).
+    'serialize'  causes the serialized form of any non-text content to be returned (scary).
+    'fail'       causes an exception to be thrown for non-text content (strict).
+
+
+== Caveats ==
+
+There are some changes in behavior that might be surprising to users:
+
+* Javascript and CSS pages are no longer parsed as wikitext (though pre-save transform is still applied). Most
+importantly, this means that links, including categorization links, contained in the code will not work.
+
+* With $wgContentHandlerUseDB = false, pages can not be moved in a way that would change the
+default model. E.g. [[MediaWiki:foo.js]] can not be moved to [[MediaWiki:foo bar]], but can still be moved to
+[[User:John/foo.js]]. Also, in this mode, changing the default content model for a page (e.g. by changing
+$wgNamespaceContentModels) may cause it to become inaccessible.
+
+* action=edit will fail for pages with non-text content, unless the respective ContentHandler implementation has
+provided a specialized handler for the edit action. This is true for the API as well.
+
+* action=raw will fail for all non-text content. This seems better than serving content in other formats to an
+unsuspecting recipient. This will also cause client-side diffs to fail.
+
+* File pages provide their own action overrides that do not combine gracefully with any custom handlers defined by a
+ContentHandler. If for example a File page used a content model with a custom revert action, this would be overridden by
+WikiFilePage's handler for the revert action.

+Some information about database access in MediaWiki.
+By Tim Starling, January 2006.
+
+------------------------------------------------------------------------
+    Database layout
+------------------------------------------------------------------------
+
+For information about the MediaWiki database layout, such as a 
+description of the tables and their contents, please see:
+  https://www.mediawiki.org/wiki/Manual:Database_layout
+  https://phabricator.wikimedia.org/diffusion/MW/browse/master/maintenance/tables.sql
+
+
+------------------------------------------------------------------------
+    API
+------------------------------------------------------------------------
+
+To make a read query, something like this usually suffices:
+
+$dbr = wfGetDB( DB_REPLICA );
+$res = $dbr->select( /* ...see docs... */ );
+foreach ( $res as $row ) {
+	...
+}
+
+For a write query, use something like:
+
+$dbw = wfGetDB( DB_MASTER );
+$dbw->insert( /* ...see docs... */ );
+
+We use the convention $dbr for read and $dbw for write to help you keep
+track of whether the database object is a slave (read-only) or a master
+(read/write). If you write to a slave, the world will explode. Or to be
+precise, a subsequent write query which succeeded on the master may fail
+when replicated to the slave due to a unique key collision. Replication
+on the slave will stop and it may take hours to repair the database and
+get it back online. Setting read_only in my.cnf on the slave will avoid
+this scenario, but given the dire consequences, we prefer to have as
+many checks as possible.
+
+We provide a query() function for raw SQL, but the wrapper functions
+like select() and insert() are usually more convenient. They take care
+of things like table prefixes and escaping for you. If you really need
+to make your own SQL, please read the documentation for tableName() and
+addQuotes(). You will need both of them.
+
+
+------------------------------------------------------------------------
+    Basic query optimisation
+------------------------------------------------------------------------
+
+MediaWiki developers who need to write DB queries should have some
+understanding of databases and the performance issues associated with
+them. Patches containing unacceptably slow features will not be
+accepted. Unindexed queries are generally not welcome in MediaWiki,
+except in special pages derived from QueryPage. It's a common pitfall
+for new developers to submit code containing SQL queries which examine
+huge numbers of rows. Remember that COUNT(*) is O(N), counting rows in a
+table is like counting beans in a bucket.
+
+
+------------------------------------------------------------------------
+    Replication
+------------------------------------------------------------------------
+
+The largest installation of MediaWiki, Wikimedia, uses a large set of
+slave MySQL servers replicating writes made to a master MySQL server. It
+is important to understand the issues associated with this setup if you
+want to write code destined for Wikipedia.
+
+It's often the case that the best algorithm to use for a given task
+depends on whether or not replication is in use. Due to our unabashed
+Wikipedia-centrism, we often just use the replication-friendly version,
+but if you like, you can use wfGetLB()->getServerCount() > 1 to
+check to see if replication is in use.
+
+=== Lag ===
+
+Lag primarily occurs when large write queries are sent to the master.
+Writes on the master are executed in parallel, but they are executed in
+serial when they are replicated to the slaves. The master writes the
+query to the binlog when the transaction is committed. The slaves poll
+the binlog and start executing the query as soon as it appears. They can
+service reads while they are performing a write query, but will not read
+anything more from the binlog and thus will perform no more writes. This
+means that if the write query runs for a long time, the slaves will lag
+behind the master for the time it takes for the write query to complete.
+
+Lag can be exacerbated by high read load. MediaWiki's load balancer will
+stop sending reads to a slave when it is lagged by more than 30 seconds.
+If the load ratios are set incorrectly, or if there is too much load
+generally, this may lead to a slave permanently hovering around 30
+seconds lag.
+
+If all slaves are lagged by more than 30 seconds, MediaWiki will stop
+writing to the database. All edits and other write operations will be
+refused, with an error returned to the user. This gives the slaves a
+chance to catch up. Before we had this mechanism, the slaves would
+regularly lag by several minutes, making review of recent edits
+difficult.
+
+In addition to this, MediaWiki attempts to ensure that the user sees
+events occurring on the wiki in chronological order. A few seconds of lag
+can be tolerated, as long as the user sees a consistent picture from
+subsequent requests. This is done by saving the master binlog position
+in the session, and then at the start of each request, waiting for the
+slave to catch up to that position before doing any reads from it. If
+this wait times out, reads are allowed anyway, but the request is
+considered to be in "lagged slave mode". Lagged slave mode can be
+checked by calling wfGetLB()->getLaggedSlaveMode(). The only
+practical consequence at present is a warning displayed in the page
+footer.
+
+=== Lag avoidance ===
+
+To avoid excessive lag, queries which write large numbers of rows should
+be split up, generally to write one row at a time. Multi-row INSERT ...
+SELECT queries are the worst offenders should be avoided altogether.
+Instead do the select first and then the insert.
+
+=== Working with lag ===
+
+Despite our best efforts, it's not practical to guarantee a low-lag
+environment. Lag will usually be less than one second, but may
+occasionally be up to 30 seconds. For scalability, it's very important
+to keep load on the master low, so simply sending all your queries to
+the master is not the answer. So when you have a genuine need for
+up-to-date data, the following approach is advised:
+
+1) Do a quick query to the master for a sequence number or timestamp 2)
+Run the full query on the slave and check if it matches the data you got
+from the master 3) If it doesn't, run the full query on the master
+
+To avoid swamping the master every time the slaves lag, use of this
+approach should be kept to a minimum. In most cases you should just read
+from the slave and let the user deal with the delay.
+
+
+------------------------------------------------------------------------
+    Lock contention
+------------------------------------------------------------------------
+
+Due to the high write rate on Wikipedia (and some other wikis),
+MediaWiki developers need to be very careful to structure their writes
+to avoid long-lasting locks. By default, MediaWiki opens a transaction
+at the first query, and commits it before the output is sent. Locks will
+be held from the time when the query is done until the commit. So you
+can reduce lock time by doing as much processing as possible before you
+do your write queries.
+
+Often this approach is not good enough, and it becomes necessary to
+enclose small groups of queries in their own transaction. Use the
+following syntax:
+
+$dbw = wfGetDB( DB_MASTER );
+$dbw->begin( __METHOD__ );
+/* Do queries */
+$dbw->commit( __METHOD__ );
+
+Use of locking reads (e.g. the FOR UPDATE clause) is not advised. They
+are poorly implemented in InnoDB and will cause regular deadlock errors.
+It's also surprisingly easy to cripple the wiki with lock contention.
+
+Instead of locking reads, combine your existence checks into your write
+queries, by using an appropriate condition in the WHERE clause of an
+UPDATE, or by using unique indexes in combination with INSERT IGNORE.
+Then use the affected row count to see if the query succeeded.
+
+------------------------------------------------------------------------
+    Supported DBMSs
+------------------------------------------------------------------------
+
+MediaWiki is written primarily for use with MySQL. Queries are optimized
+for it and its schema is considered the canonical version. However,
+MediaWiki does support the following other DBMSs to varying degrees.
+
+* PostgreSQL
+* SQLite
+* Oracle
+* MSSQL
+
+More information can be found about each of these databases (known issues,
+level of support, extra configuration) in the "databases" subdirectory in
+this folder.
+
+------------------------------------------------------------------------
+    Use of GROUP BY
+------------------------------------------------------------------------
+
+MySQL supports GROUP BY without checking anything in the SELECT clause. 
+Other DBMSs (especially Postgres) are stricter and require that all the 
+non-aggregate items in the SELECT clause appear in the GROUP BY. For 
+this reason, it is highly discouraged to use SELECT * with GROUP BY 
+queries.

+This document describes the state of Postgres support in MediaWiki.
+
+
+== Overview ==
+
+Support for PostgreSQL has been available since version 1.7
+of MediaWiki, and is fairly well maintained. The main code
+is very well integrated, while extensions are very hit and miss.
+Still, it is probably the most supported database after MySQL.
+Much of the work in making MediaWiki database-agnostic came
+about through the work of creating Postgres support.
+
+
+== Required versions ==
+
+The current minimum version of PostgreSQL for MediaWiki is 8.1.
+It is expected that this will be raised to 8.3 at some point,
+as 8.1 and 8.2 are nearing end of life.
+
+
+
+== Database schema ==
+
+Postgres has its own schema file at maintenance/postgres/tables.sql.
+
+The goal is to keep this file as close as possible to the canonical
+schema at maintenance/tables.sql, but without copying over
+all the usage comments. General notes on the conversion:
+
+* The use of a true TIMESTAMP rather than the text string that
+MySQL uses is highly encouraged. There are still places in the
+code (especially extensions) which make assumptions about the
+textual nature of timestamp fields, but these can almost always
+be programmed around.
+
+* Although Postgres has a true BOOLEAN type, boolean columns
+are always mapped to SMALLINT, as the code does not always treat
+the column as a boolean (which is limited to accepting true,
+false, 0, 1, t, or f)
+
+* The default data type for all VARCHAR, CHAR, and VARBINARY
+columns should simply be TEXT. The only exception is
+when VARBINARY is used to store true binary data, such as
+the math_inputhash column, in which case BYTEA should be used.
+
+* All integer variants should generally be mapped to INTEGER.
+There is small-to-no advantage in using SMALLINT versus
+INTEGER in Postgres, and the possibility of running out of
+room outweighs such concerns. The columns that are BIGINT
+in other schemas should be INTEGER as well, as none of them
+so far are even remotely likely to reach the 32 billion
+limit of an INTEGER.
+
+* Blobs (blob, tinyblog, mediumblob) should be mapped to TEXT
+whenever possible, and to BYTEA if they are known to contain
+binary data.
+
+* All length modifiers on data types should be removed. If
+they are on an INTEGER, it's probably an error, and if on
+any text-based field, simply using TEXT is preferred.
+
+* Sequences should be explicitly named rather than using
+SERIAL, as the code can depend on having a specific name.
+
+* Foreign keys should be used when possible. This makes things
+both easier and harder in the code, but most of the major
+problems have now been overcome. Always add an explicit ON DELETE
+clause, and consider carefully what choice to use (all things
+considered, prefer CASCADE).
+
+* The use of CIDR should be done very carefully, because the code
+will sometimes want to store things such as an empty string or
+other non-IP value in the column. When in doubt, use TEXT.
+
+* Indexes should be created using the original MySQL tables.sql
+as a guide, but keeping in mind the ability of Postgres to use
+partial indexes, functional indexes, and bitmaps. The index names
+should be logical but are not too important, as they are never
+referenced directly by the code (unlike sequence names). Most of
+the indexes in the file as of this writing are there due to production
+testing of expensive queries on a busy wiki.
+
+
+== Keeping in sync with tables.sql ==
+
+The script maintenance/postgres/compare_schemas.pl should be
+periodically run. It will parse both "tables.sql" files and
+produce any differences found. Such differences should be fixed
+or exceptions specifically carved out by editing the script
+itself. This script has also been very useful in finding problems
+in maintenance/tables.sql itself, as it is very strict in the
+format it expects things to be in. :)
+
+
+== MySQL differences ==
+
+The major differences between MySQL and Postgres are represented as 
+methods in the Database class. For example, implicitGroupby() is 
+true for MySQL and false for Postgres. This means that in those 
+places where the code does not add all the non-aggregate items 
+from the SELECT clause to the GROUP BY, we can add them in, but in 
+a conditional manner with the above method, as simply adding them 
+all in to the main query may cause performance problems with 
+MySQL.
+
+
+== Getting help ==
+
+In addition to the normal venues (MediaWiki mailing lists
+and IRC channels), the #postgresql channel on irc.freenode.net
+is a friendly and expert resource if you should encounter a
+problem with your Postgres-enabled MediaWiki.

+A few of the database updates required by various functions here can be
+deferred until after the result page is displayed to the user.  For example,
+updating the view counts, updating the linked-to tables after a save, etc.  PHP
+does not yet have any way to tell the server to actually return and disconnect
+while still running these updates (as a Java servelet could), but it might have
+such a feature in the future.
+
+We handle these by creating a deferred-update object and putting those objects
+on a global list, then executing the whole list after the page is displayed. We
+don't do anything smart like collating updates to the same table or such
+because the list is almost always going to have just one item on it, if that,
+so it's not worth the trouble.
+
+Since 1.6 there is a 'job queue' in the jobs table, which is used to update
+link tables of transcluding pages after edits; this may be extended in the
+future to more general background tasks.
+
+Job queue items are fetched out of the queue and run either at a random rate
+during regular page views (by default) or by a batch process which can be run
+via maintenance/runJobs.php.
+
+Currently there are a few different types of jobs:
+
+  refreshLinks
+    Used to refresh the database tables that store the links between pages.
+    When a page is changed, all pages using that page are also cleared by
+    inserting a new job for all those pages. Each job refreshes only one page.
+
+  htmlCacheUpdate
+    Clear caches when a template is changed to ensure that changes can be seen.
+    Each job clears $wgUpdateRowsPerJob pages (300 by default).
+
+  enotifNotify
+    Used to send mail using the job queue.

+    for things like the user's settings, name, etc. Handles the details of
+    getting and saving to the "user" table of the database, and dealing with
+    sessions and cookies.
+
+  OutputPage
+    Encapsulates the entire HTML page that will be sent in response to any
+    server request. It is used by calling its functions to add text, headers,
+    etc., in any order, and then calling output() to send it all. It could be
+    easily changed to send incrementally if that becomes useful, but I prefer
+    the flexibility. This should also do the output encoding. The system
+    allocates a global one in $wgOut.
+
+  Title
+    Represents the title of an article, and does all the work of translating
+    among various forms such as plain text, URL, database key, etc. For
+    convenience, and for historical reasons, it also represents a few features
+    of articles that don't involve their text, such as access rights.
+    See also title.txt.
+
+  Article
+    Encapsulates access to the "page" table of the database. The object
+    represents a an article, and maintains state such as text (in Wikitext
+    format), flags, etc.
+
+  Revision
+    Encapsulates individual page revision data and access to the
+    revision/text/blobs storage system. Higher-level code should never touch
+    text storage directly; this class mediates it.
+
+  Skin
+    Encapsulates a "look and feel" for the wiki. All of the functions that
+    render HTML, and make choices about how to render it, are here, and are
+    called from various other places when needed (most notably,
+    OutputPage::addWikiText()). The StandardSkin object is a complete
+    implementation, and is meant to be subclassed with other skins that may
+    override some of its functions. The User object contains a reference to a
+    skin (according to that user's preference), and so rather than having a
+    global skin object we just rely on the global User and get the skin with
+    $wgUser->getSkin().
+    See also skin.txt.
+
+  Language
+    Represents the language used for incidental text, and also has some
+    character encoding functions and other locale stuff. The current user
+    interface language is instantiated as $wgLang, and the local content
+    language as $wgContLang; be sure to use the *correct* language object
+    depending upon the circumstances.
+    See also language.txt.
+
+  Parser
+    Class used to transform wikitext to html.
+
+  LinkCache
+    Keeps information on existence of articles. See linkcache.txt.
+
+Naming/coding conventions:
+
+  These are meant to be descriptive, not dictatorial; I won't presume to tell
+  you how to program, I'm just describing the methods I chose to use for myself.
+  If you do choose to follow these guidelines, it will probably be easier for
+  you to collaborate with others on the project, but if you want to contribute
+  without bothering, by all means do so (and don't be surprised if I reformat
+  your code).
+
+  - I have the code indented with tabs to save file size and so that users can
+    set their tab stops to any depth they like. I use 4-space tab stops, which
+    work well. I also use K&R brace matching style. I know that's a religious
+    issue for some, so if you want to use a style that puts opening braces on
+    the next line, that's OK too, but please don't use a style where closing
+    braces don't align with either the opening brace on its own line or the
+    statement that opened the block--that's confusing as hell.
+
+  - Certain functions and class members are marked with /* private */, rather
+    than being marked as such. This is a hold-over from PHP 4, which didn't
+    support proper visibilities. You should not access things marked in this
+    manner outside the class/inheritance line as this code is subjected to be
+    updated in a manner that enforces this at some time in the near future, and
+    things will break. New code should use the standard method of setting
+    visibilities as normal.
+
+  - Globals are particularly evil in PHP; it sets a lot of them automatically
+    from cookies, query strings, and such, leading to namespace conflicts; when
+    a variable name is used in a function, it is silently declared as a new
+    local masking the global, so you'll get weird error because you forgot the
+    global declaration; lack of static class member variables means you have to
+    use globals for them, etc. Evil, evil.
+
+    I think I've managed to pare down the number of globals we use to a scant
+    few dozen or so, and I've prefixed them all with "wg" so you can spot errors
+    better (odds are, if you see a "wg" variable being used in a function that
+    doesn't declare it global, that's probably an error).
+
+    Other conventions: Top-level functions are wfFuncname(), names of session
+    variables are wsName, cookies wcName, and form field values wpName ("p" for
+    "POST").

+This document is intended to provide useful advice for parties seeking to
+redistribute MediaWiki to end users. It's targeted particularly at maintainers
+for Linux distributions, since it's been observed that distribution packages of
+MediaWiki often break. We've consistently had to recommend that users seeking
+support use official tarballs instead of their distribution's packages, and
+this often solves whatever problem the user is having. It would be nice if
+this could change.
+
+== Background: why web applications are different ==
+
+MediaWiki is intended to be usable on any web host that provides support for
+PHP and a database. Many users of low-end shared hosting have very limited
+access to their machine: often only FTP access to some subdirectory of the web
+root. Support for these users entails several restrictions, such as:
+
+  1) We cannot require installation of any files outside the web root. Few of
+  our users have access to directories like /usr or /etc.
+  2) We cannot require the ability to run any utility on the command line.
+  Many shared hosts have exec() and similar PHP functions disabled.
+  3) We cannot assume that the software has write access anywhere useful. The
+  user account that MediaWiki (including its installer) runs under is often
+  different from the account the user used to upload the files, and we might be
+  restricted by PHP settings such as safe mode or open_basedir.
+  4) We cannot assume that the software even has read access anywhere useful.
+  Many shared hosts run all users' web applications under the same user, so
+  they can't rely on Unix permissions, and must forbid reads to even standard
+  directories like /tmp lest users read each others' files.
+  5) We cannot assume that the user has the ability to install or run any
+  programs not written as web-accessible PHP scripts.
+
+Since anything that works on cheap shared hosting will work if you have shell
+or root access too, MediaWiki's design is based around catering to the lowest
+common denominator. Although we support higher-end setups as well (like
+Wikipedia!), the way many things work by default is tailored toward shared
+hosting. These defaults are unconventional from the point of view of normal
+(non-web) applications -- they might conflict with distributors' policies, and
+they certainly aren't ideal for someone who's installing MediaWiki as root.
+
+== Directory structure ==
+
+Because of constraint (1) above, MediaWiki does not conform to normal
+Unix filesystem layout. Hopefully we'll offer direct support for standard
+layouts in the future, but for now *any change to the location of files is
+unsupported*. Moving things and leaving symlinks will *probably* not break
+anything, but it is *strongly* advised not to try any more intrusive changes to
+get MediaWiki to conform more closely to your filesystem hierarchy. Any such
+attempt will almost certainly result in unnecessary bugs.
+
+The standard recommended location to install MediaWiki, relative to the web
+root, is /w (so, e.g., /var/www/w). Rewrite rules can then be used to enable
+"pretty URLs" like /wiki/Article instead of /w/index.php?title=Article. (This
+is the convention Wikipedia uses.)  In theory, it should be possible to enable
+the appropriate rewrite rules by default, if you can reconfigure the web
+server, but you'd need to alter LocalSettings.php too. See
+<https://www.mediawiki.org/wiki/Manual:Short_URL> for details on short URLs.
+
+If you really must mess around with the directory structure, note that the
+following files *must* all be web-accessible for MediaWiki to function
+correctly:
+
+  * api.php, img_auth.php, index.php, load.php, opensearch_desc.php, thumb.php,
+  profileinfo.php. These are the entry points for normal usage. This list may be
+  incomplete and is subject to change.
+  * mw-config/index.php: Used for web-based installation (sets up the database,
+  prompts for the name of the wiki, etc.).
+  * images/: Used for uploaded files. This could be somewhere else if
+  $wgUploadDirectory and $wgUploadPath are changed appropriately.
+  * skins/*/: Subdirectories of skins/ contain CSS and JavaScript files that
+  must be accessible to web browsers. The PHP files and Skin.sample in skins/
+  don't need to be accessible. This could be somewhere else if
+  $wgStyleDirectory and $wgStylePath are changed appropriately.
+  * extensions/: Many extensions include CSS and JavaScript files in their
+  extensions directory, and will break if they aren't web-accessible. Some
+  extensions might theoretically provide additional entry points as well, at
+  least in principle.
+
+But all files should keep their position relative to the web-visible
+installation directory no matter what. If you must move includes/ somewhere in
+/usr/share, provide a symlink from /var/www/w. If you don't, you *will* break
+something. You have been warned.
+
+== Configuration ==
+
+MediaWiki is configured using LocalSettings.php. This is a PHP file that's
+generated when the user visits mw-config/index.php to install the software, and
+which the user can edit by hand thereafter. It's just a plain old PHP file,
+and can contain any PHP statements. It usually sets global variables that are
+used for configuration, and includes files used by any extensions.
+
+Distributors can easily change the installer behavior, including LocalSettings
+generated, by placing their overrides into mw-config/overrides directory. Doing
+that is highly preferred to modifying MediaWiki code directly. See
+mw-config/overrides/README for more details and examples.
+
+There's a new maintenance/install.php script which could be used for performing
+an install through the command line.
+
+Some configuration options that distributors might be in a position to set
+intelligently:
+
+  * $wgEmergencyContact: An e-mail address that can be used to contact the wiki
+  administrator. By default, "wikiadmin@ServerName".
+  * $wgPasswordSender: The e-mail address to use when sending password e-mails.
+  By default, "MediaWiki Mail <apache@ServerName>".
+	(with ServerName guessed from the http request)
+  * $wgSMTP: Can be configured to use SMTP for mail sending instead of PHP
+  mail().
+
+== Updates ==
+
+The correct way for updating a wiki is to update the files and then run from 
+command line the maintenance/update.php script (with appropriate parameters if
+files were moved). It will perform all the needed steps to update the database 
+schema and contents to the version from whatever old one it has.
+Any package manager which replaces the files but doesn't update the db is leaving
+an inconsistent wiki that may produce blank pages (php errors) when new features 
+using the changed schema would be used.
+
+Since MediaWiki 1.17 it is possible to upgrade using the web installer by providing
+an arbitrary secret value stored as $wgUpgradeKey in LocalSettings (older versions 
+needed to rename LocalSettings.php in order to upgrade using the installer).
+
+== Documentation ==
+
+MediaWiki's official documentation is split between two places: the source
+code, and <https://www.mediawiki.org/>. The source code documentation is written
+exclusively by developers, and so is likely to be reliable (at worst,
+outdated). However, it can be pretty sparse. mediawiki.org documentation is
+often much more thorough, but it's maintained by a wiki that's open to
+anonymous edits, so its quality is sometimes sketchy -- don't assume that
+anything there is officially endorsed!
+
+== Upstream ==
+
+MediaWiki is a project hosted and led by the Wikimedia Foundation, the
+not-for-profit charity that operates Wikipedia. Wikimedia employs the lead
+developer and several other paid developers, but commit access is given out
+liberally and there are multiple very active volunteer developers as well. A
+list of developers can be found at <https://www.mediawiki.org/wiki/Developers>.
+
+MediaWiki's bug tracker is at <https://phabricator.wikimedia.org>. However, you
+might find that the best place to post if you want to get developers' attention
+is the wikitech-l mailing list
+<https://lists.wikimedia.org/mailman/listinfo/wikitech-l>. Posts to wikitech-l
+will inevitably be read by multiple experienced MediaWiki developers. There's
+also an active IRC chat at <irc://irc.freenode.net/mediawiki>, where there are
+usually several developers at reasonably busy times of day.
+
+Our Git repositories are hosted at <https://gerrit.wikimedia.org>, see
+<https://www.mediawiki.org/wiki/Gerrit> for more information. Patches should
+be submitted there. If you know which developers are best suited to review your
+patch, add them to it, otherwise ask on IRC to get better review time.
+
+All redistributors of MediaWiki should be subscribed to mediawiki-announce
+<https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce>. It's
+extremely low-traffic, with an average of less than one post per month. All
+new releases are announced here, including critical security updates.
+
+== Useful software to install ==
+
+There are several other pieces of software that MediaWiki can make good use of.
+Distributors might choose to install these automatically with MediaWiki and
+perhaps configure it to use them (see Configuration section of this document):
+
+  * APC (Alternative PHP Cache), XCache, or similar: Will greatly speed up the
+  execution of MediaWiki, and all other PHP applications, at some cost in
+  memory usage. Will be used automatically for the most part.
+  * clamav: Can be used for virus scanning of uploaded files. Enable with
+  "$wgAntivirus = 'clamav';".
+  * DjVuLibre: Allows processing of DjVu files. To enable this, set
+  "$wgDjvuDump = 'djvudump'; $wgDjvuRenderer = 'ddjvu'; $wgDjvuTxt = 'djvutxt';".
+  * HTML Tidy: Fixes errors in HTML at runtime. Can be enabled with 
+	"$wgUseTidy = true;".
+  * ImageMagick: For resizing images. "$wgUseImageMagick = true;" will enable
+  it. PHP's GD can also be used, but ImageMagick is preferable.
+  * HTTP cache such as Varnish or Squid: can provide a drastic speedup and a
+  major cut in resource consumption, but enabling it may interfere with other
+  applications. It might be suitable for a separate package. For setup details, see:
+  - <https://www.mediawiki.org/wiki/Manual:Varnish_caching>
+  - <https://www.mediawiki.org/wiki/Manual:Squid_caching>
+  * rsvg or other SVG rasterizer: ImageMagick can be used for SVG support, but
+  is not ideal. Wikipedia (as of the time of this writing) uses rsvg. To
+  enable, set "$wgSVGConverter = 'rsvg';" (or other as appropriate).
+
+MediaWiki uses some standard GNU utilities as well, such as diff and diff3. If
+these are present in /usr/bin or some other reasonable location, they will be
+configured automatically on install.
+
+MediaWiki also has a "job queue" that handles background processing. Because
+shared hosts often don't provide access to cron, the job queue is run on every
+page view by default. This means the background tasks aren't really done in
+the background. Busy wikis can set $wgJobRunRate to 0 and run
+maintenance/runJobs.php periodically out of cron. Distributors probably
+shouldn't set this up as a default, however, since the extra cron job is
+unnecessary overhead for a little-used wiki.
+
+== Web server configuration ==
+
+MediaWiki includes several .htaccess files to restrict access to some
+directories. If the web server is not configured to support these files, and
+the relevant directories haven't been moved someplace inaccessible anyway (e.g.
+symlinked in /usr/share with the web server configured to not follow symlinks),
+then it might be useful to deny web access to those directories in the web
+server's configuration.

+
+Globals are evil. The original MediaWiki code relied on globals for processing
+context far too often. MediaWiki development since then has been a story of
+slowly moving context out of global variables and into objects. Storing
+processing context in object member variables allows those objects to be reused
+in a much more flexible way. Consider the elegance of:
+
+    # Generate the article HTML as if viewed by a web request
+    $article = new Article( Title::newFromText( $t ) );
+    $article->view();
+ 
+versus
+
+    # Save current globals
+    $oldTitle = $wgTitle;
+    $oldArticle = $wgArticle;
+
+    # Generate the HTML
+    $wgTitle = Title::newFromText( $t );
+    $wgArticle = new Article;
+    $wgArticle->view();
+
+    # Restore globals
+    $wgTitle = $oldTitle
+    $wgArticle = $oldArticle
+
+Some of the current MediaWiki developers have an idle fantasy that some day,
+globals will be eliminated from MediaWiki entirely, replaced by an application
+object which would be passed to constructors. Whether that would be an
+efficient, convenient solution remains to be seen, but certainly PHP 5 makes
+such object-oriented programming models easier than they were in previous
+versions.
+
+For the time being though, MediaWiki programmers will have to work in an
+environment with some global context. At the time of writing, 418 globals were
+initialised on startup by MediaWiki. 304 of these were configuration settings,
+which are documented in DefaultSettings.php. There is no comprehensive
+documentation for the remaining 114 globals, however some of the most important
+ones are listed below. They are typically initialised either in index.php or in
+Setup.php.
+
+For a description of the classes, see design.txt.
+
+$wgTitle
+	Title object created from the request URL.
+
+$wgOut
+	OutputPage object for HTTP response.
+
+$wgUser
+	User object for the user associated with the current request.
+
+$wgLang
+	Language object selected by user preferences.
+
+$wgContLang
+	Language object associated with the wiki being viewed.
+
+$wgParser
+	Parser object. Parser extensions register their hooks here.
+
+$wgRequest
+	WebRequest object, to get request data
+
+$wgMemc, $messageMemc, $parserMemc
+	Object caches

+hooks.txt
+
+This document describes how event hooks work in MediaWiki; how to add hooks for
+an event; and how to run hooks for an event.
+
+==Glossary==
+
+event
+     Something that happens with the wiki. For example: a user logs in. A wiki
+     page is saved. A wiki page is deleted. Often there are two events
+     associated with a single action: one before the code is run to make the
+     event happen, and one after. Each event has a name, preferably in
+     CamelCase. For example, 'UserLogin', 'PageContentSave',
+     'PageContentSaveComplete', 'ArticleDelete'.
+
+hook
+     A clump of code and data that should be run when an event happens. This can
+     be either a function and a chunk of data, or an object and a method.
+
+hook function
+     The function part of a hook.
+
+==Rationale==
+
+Hooks allow us to decouple optionally-run code from code that is run for
+everyone. It allows MediaWiki hackers, third-party developers and local
+administrators to define code that will be run at certain points in the mainline
+code, and to modify the data run by that mainline code. Hooks can keep mainline
+code simple, and make it easier to write extensions. Hooks are a principled
+alternative to local patches.
+
+Consider, for example, two options in MediaWiki. One reverses the order of a
+title before displaying the article; the other converts the title to all
+uppercase letters. Currently, in MediaWiki code, we would handle this as follows
+(note: not real code, here):
+
+	function showAnArticle( $article ) {
+		global $wgReverseTitle, $wgCapitalizeTitle;
+
+		if ( $wgReverseTitle ) {
+			wfReverseTitle( $article );
+		}
+
+		if ( $wgCapitalizeTitle ) {
+			wfCapitalizeTitle( $article );
+		}
+
+		# code to actually show the article goes here
+	}
+
+An extension writer, or a local admin, will often add custom code to the
+function -- with or without a global variable. For example, someone wanting
+email notification when an article is shown may add:
+
+	function showAnArticle( $article ) {
+		global $wgReverseTitle, $wgCapitalizeTitle, $wgNotifyArticle;
+
+		if ( $wgReverseTitle ) {
+			wfReverseTitle( $article );
+		}
+
+		if ( $wgCapitalizeTitle ) {
+			wfCapitalizeTitle( $article );
+		}
+
+		# code to actually show the article goes here
+
+		if ( $wgNotifyArticle ) {
+			wfNotifyArticleShow( $article );
+		}
+	}
+
+Using a hook-running strategy, we can avoid having all this option-specific
+stuff in our mainline code. Using hooks, the function becomes:
+
+	function showAnArticle( $article ) {
+		if ( Hooks::run( 'ArticleShow', array( &$article ) ) ) {
+			# code to actually show the article goes here
+
+			Hooks::run( 'ArticleShowComplete', array( &$article ) );
+		}
+	}
+
+We've cleaned up the code here by removing clumps of weird, infrequently used
+code and moving them off somewhere else. It's much easier for someone working
+with this code to see what's _really_ going on, and make changes or fix bugs.
+
+In addition, we can take all the code that deals with the little-used
+title-reversing options (say) and put it in one place. Instead of having little
+title-reversing if-blocks spread all over the codebase in showAnArticle,
+deleteAnArticle, exportArticle, etc., we can concentrate it all in an extension
+file:
+
+	function reverseArticleTitle( $article ) {
+		# ...
+	}
+
+	function reverseForExport( $article ) {
+		# ...
+	}
+
+The setup function for the extension just has to add its hook functions to the
+appropriate events:
+
+	setupTitleReversingExtension() {
+		global $wgHooks;
+
+		$wgHooks['ArticleShow'][] = 'reverseArticleTitle';
+		$wgHooks['ArticleDelete'][] = 'reverseArticleTitle';
+		$wgHooks['ArticleExport'][] = 'reverseForExport';
+	}
+
+Having all this code related to the title-reversion option in one place means
+that it's easier to read and understand; you don't have to do a grep-find to see
+where the $wgReverseTitle variable is used, say.
+
+If the code is well enough isolated, it can even be excluded when not used --
+making for some slight savings in memory and load-up performance at runtime.
+Admins who want to have all the reversed titles can add:
+
+	require_once 'extensions/ReverseTitle.php';
+
+...to their LocalSettings.php file; those of us who don't want or need it can
+just leave it out.
+
+The extensions don't even have to be shipped with MediaWiki; they could be
+provided by a third-party developer or written by the admin him/herself.
+
+==Writing hooks==
+
+A hook is a chunk of code run at some particular event. It consists of:
+
+  * a function with some optional accompanying data, or
+  * an object with a method and some optional accompanying data.
+
+Hooks are registered by adding them to the global $wgHooks array for a given
+event. All the following are valid ways to define hooks:
+
+	$wgHooks['EventName'][] = 'someFunction'; # function, no data
+	$wgHooks['EventName'][] = array( 'someFunction', $someData );
+	$wgHooks['EventName'][] = array( 'someFunction' ); # weird, but OK
+
+	$wgHooks['EventName'][] = $object; # object only
+	$wgHooks['EventName'][] = array( $object, 'someMethod' );
+	$wgHooks['EventName'][] = array( $object, 'someMethod', $someData );
+	$wgHooks['EventName'][] = array( $object ); # weird but OK
+
+When an event occurs, the function (or object method) will be called with the
+optional data provided as well as event-specific parameters. The above examples
+would result in the following code being executed when 'EventName' happened:
+
+	# function, no data
+	someFunction( $param1, $param2 )
+	# function with data
+	someFunction( $someData, $param1, $param2 )
+
+	# object only
+	$object->onEventName( $param1, $param2 )
+	# object with method
+	$object->someMethod( $param1, $param2 )
+	# object with method and data
+	$object->someMethod( $someData, $param1, $param2 )
+
+Note that when an object is the hook, and there's no specified method, the
+default method called is 'onEventName'. For different events this would be
+different: 'onArticleSave', 'onUserLogin', etc.
+
+The extra data is useful if we want to use the same function or object for
+different purposes. For example:
+
+	$wgHooks['PageContentSaveComplete'][] = array( 'ircNotify', 'TimStarling' );
+	$wgHooks['PageContentSaveComplete'][] = array( 'ircNotify', 'brion' );
+
+This code would result in ircNotify being run twice when an article is saved:
+once for 'TimStarling', and once for 'brion'.
+
+Hooks can return three possible values:
+
+  * No return value (or null): the hook has operated successfully. Previously,
+    true was required. This is the default since MediaWiki 1.23.
+  * "some string": an error occurred; processing should stop and the error
+                   should be shown to the user
+  * false: the hook has successfully done the work necessary and the calling
+           function should skip
+
+The last result would be for cases where the hook function replaces the main
+functionality. For example, if you wanted to authenticate users to a custom
+system (LDAP, another PHP program, whatever), you could do:
+
+	$wgHooks['UserLogin'][] = array( 'ldapLogin', $ldapServer );
+
+	function ldapLogin( $username, $password ) {
+		# log user into LDAP
+		return false;
+	}
+
+Returning false makes less sense for events where the action is complete, and
+will normally be ignored.
+
+Note that none of the examples made use of create_function() as a way to
+attach a function to a hook. This is known to cause problems (notably with
+Special:Version), and should be avoided when at all possible.
+
+==Using hooks==
+
+A calling function or method uses the Hooks::run() function to run the hooks
+related to a particular event, like so:
+
+	class Article {
+		# ...
+		function protect() {
+			global $wgUser;
+
+			// Avoid PHP 7.1 warning from passing $this by reference
+			$article = $this;
+
+			if ( Hooks::run( 'ArticleProtect', [ &$article, &$wgUser ] ) ) {
+				# protect the article
+				Hooks::run( 'ArticleProtectComplete', [ &$article, &$wgUser ] );
+			}
+		}
+	}
+
+Hooks::run() returns true if the calling function should continue processing
+(the hooks ran OK, or there are no hooks to run), or false if it shouldn't (an
+error occurred, or one of the hooks handled the action already). Checking the
+return value matters more for "before" hooks than for "complete" hooks.
+
+Hooks::run() was added in MediaWiki 1.18, before that the global function
+wfRunHooks must be used, which was deprecated in MediaWiki 1.25.
+
+Note that hook parameters are passed in an array; this is a necessary
+inconvenience to make it possible to pass reference values (that can be changed)
+into the hook code. Also note that earlier versions of wfRunHooks took a
+variable number of arguments; the array() calling protocol came about after
+MediaWiki 1.4rc1.
+
+==Events and parameters==
+
+This is a list of known events and parameters; please add to it if you're going
+to add events to the MediaWiki code.

+
+'AfterFinalPageOutput': Nearly at the end of OutputPage::output() but
+before OutputPage::sendCacheControl() and final ob_end_flush() which

+$output: The OutputPage object where output() was called
+
+'AfterImportPage': When a page import is completed.
+$title: Title under which the revisions were imported
+$foreignTitle: ForeignTitle object based on data provided by the XML file

+in the regular way.
+$headers: Associative array of headers for the email
+$to: MailAddress object or array
+$from: From address
+$subject: Subject of the email
+$body: Body of the message

+'APIEditBeforeSave': DEPRECATED! Use EditFilterMergedContent instead.
+Before saving a page with api.php?action=edit, after
+processing request parameters. Return false to let the request fail, returning
+an error message or an <edit result="Failure"> tag if $resultArr was filled.
+Unlike for example 'EditFilterMergedContent' this also being run on undo.
+Since MediaWiki 1.25, 'EditFilterMergedContent' can also return error details
+for the API and it's recommended to use it instead of this hook.
+$editPage: the EditPage object
+$text: the text passed to the API. Note that this includes only the single
+  section for section edit, and is not necessarily the final text in case of
+  automatically resolved edit conflicts.
+&$resultArr: data in this array will be added to the API result
+
+'ApiFeedContributions::feedItem': Called to convert the result of ContribsPager
+into a FeedItem instance that ApiFeedContributions can consume. Implementors of

+  ContribsPager can be adjusted by handling the ContribsPager::reallyDoQuery
+  hook.
+$context: An IContextSource implementation.

+
+'APIGetDescription': DEPRECATED! Use APIGetDescriptionMessages instead.
+Use this hook to modify a module's description.
+&$module: ApiBase Module object
+&$desc: String description, or array of description strings
+

+  setting errors, as the deletion has already been partly carried out by this
+  point.

+injection.txt
+
+This is an overview of how MediaWiki makes use of dependency injection.
+The design described here grew from the discussion of RFC T384.
+
+
+The term "dependency injection" (DI) refers to a pattern on object oriented
+programming that tries to improve modularity by reducing strong coupling
+between classes. In practical terms, this means that anything an object needs
+to operate should be injected from the outside, the object itself should only
+know narrow interfaces, no concrete implementation of the logic it relies on.
+
+The requirement to inject everything typically results in an architecture that
+based on two main types of objects: simple value objects with no business logic
+(and often immutable), and essentially stateless service objects that use
+other service objects to operate on the value objects.
+
+As of the beginning of 2016 (MW version 1.27), MediaWiki is only starting to
+use the DI approach. Much of the code still relies on global state or direct
+instantiation, resulting in a highly cyclical dependency graph.
+
+
+== Overview ==
+The heart of the DI in MediaWiki is the central service locator,
+MediaWikiServices, which acts as the top level factory for services in
+MediaWiki. MediaWikiServices::getInstance() returns the default service
+locator instance, which can be used to gain access to default instances of
+various services. MediaWikiServices however also allows new services to be
+defined and default services to be redefined. Services are defined or
+redefined by providing a callback function, the "instantiator" function,
+that will return a new instance of the service.
+
+When MediaWikiServices::getInstance() is first called, it will create an
+instance of MediaWikiServices and populate it with the services defined
+in the files listed by $wgServiceWiringFiles, thereby "bootstrapping" the
+DI framework. Per default, $wgServiceWiringFiles lists
+includes/ServiceWiring.php, which defines all default service
+implementations, and specifies how they depend on each other ("wiring").
+
+When a new service is added to MediaWiki core, an instantiator function
+that will create the appropriate default instance for that service must
+be added to ServiceWiring.php. This makes the service available through
+the generic getService() method on the service locator returned by
+MediaWikiServices::getInstance().
+
+Extensions can add their own wiring files to $wgServiceWiringFiles, in order
+to define their own service. Extensions may also use the 'MediaWikiServices'
+hook to define or redefined services by calling methods on the default
+MediaWikiServices instance.
+
+
+It should be noted that the term "service locator" is often used to refer to a
+top level factory that is accessed directly, throughout the code, to avoid
+explicit dependency injection. In contrast, the term "DI container" is often
+used to describe a top level factory that is only accessed when services
+are created. We use the term "service locator" for the top level factory
+because it is more descriptive than "DI container", even though application
+logic is strongly discouraged from accessing MediaWikiServices directly.
+MediaWikiServices::getInstance() should ideally be accessed only in "static
+entry points" such as hook handler functions. See "Migration" below.
+
+
+== Service Reset ==
+
+Services get their configuration injected, and changes to global
+configuration variables will not have any effect on services that were already
+instantiated. This would typically be the case for low level services like
+the ConfigFactory or the ObjectCacheManager, which are used during extension
+registration. To address this issue, Setup.php resets the global service
+locator instance by calling MediaWikiServices::resetGlobalInstance() once
+configuration and extension registration is complete.
+
+Note that "unmanaged" legacy services services that manage their own singleton
+must not keep references to services managed by MediaWikiServices, to allow a
+clean reset. After the global MediaWikiServices instance got reset, any such
+references would be stale, and using a stale service will result in an error.
+
+Services should either have all dependencies injected and be themselves managed
+by MediaWikiServices, or they should use the Service Locator pattern, accessing
+service instances via the global MediaWikiServices instance state when needed.
+This ensures that no stale service references remain after a reset.
+
+
+== Configuration ==
+
+When the default MediaWikiServices instance is created, a Config object is
+provided to the constructor. This Config object represents the "bootstrap"
+configuration which will become available as the 'BootstrapConfig' service.
+As of MW 1.27, the bootstrap config is a GlobalVarConfig object providing
+access to the $wgXxx configuration variables.
+
+The bootstrap config is then used to construct a 'ConfigFactory' service,
+which in turn is used to construct the 'MainConfig' service. Application
+logic should use the 'MainConfig' service (or a more specific configuration
+object). 'BootstrapConfig' should only be used for bootstrapping basic
+services that are needed to load the 'MainConfig'.
+
+
+Note: Several well known services in MediaWiki core act as factories
+themselves, e.g. ApiModuleManager, ObjectCache, SpecialPageFactory, etc.
+The registries these factories are based on are currently managed as part of
+the configuration. This may however change in the future.
+
+
+== Migration ==
+
+This section provides some recipes for improving code modularity by reducing
+strong coupling. The dependency injection mechanism described above is an
+essential tool in this effort.
+
+Migrate access to global service instances and config variables:
+Assume Foo is a class that uses the $wgScriptPath global and calls
+wfGetDB() to get a database connection, in non-static methods.
+* Add $scriptPath as a constructor parameter and use $this->scriptPath
+  instead of $wgScriptPath.
+* Add LoadBalancer $dbLoadBalancer as a constructor parameter. Use
+  $this->dbLoadBalancer->getConnection() instead of wfGetDB().
+* Any code that calls Foo's constructor would now need to provide the
+  $scriptPath and $dbLoadBalancer. To avoid this, avoid direct instantiation
+  of services all together - see below.
+
+Migrate class-level singleton getters:
+Assume class Foo has mostly non-static methods, and provides a static
+getInstance() method that returns a singleton (or default instance).
+* Add an instantiator function for Foo into ServiceWiring.php. The instantiator
+  would do exactly what Foo::getInstance() did. However, it should
+  replace any access to global state with calls to $services->getXxx() to get a
+  service, or $services->getMainConfig()->get() to get a configuration setting.
+* Add a getFoo() method to MediaWikiServices. Don't forget to add the
+  appropriate test cases in MediaWikiServicesTest.
+* Turn Foo::getInstance() into a deprecated alias for
+  MediaWikiServices::getInstance()->getFoo(). Change all calls to
+  Foo::getInstance() to use injection (see above).
+
+Migrate direct service instantiation:
+Assume class Bar calls new Foo().
+* Add an instantiator function for Foo into ServiceWiring.php and add a getFoo()
+  method to MediaWikiServices. Don't forget to add the appropriate test cases
+  in MediaWikiServicesTest.
+* In the instantiator, replace any access to global state with calls
+  to $services->getXxx() to get a service, or $services->getMainConfig()->get()
+  to get a configuration setting.
+* The code in Bar that calls Foo's constructor should be changed to have a Foo
+  instance injected; Eventually, the only code that instantiates Foo is the
+  instantiator in ServiceWiring.php.
+* As an intermediate step, Bar's constructor could initialize the $foo member
+  variable by calling MediaWikiServices::getInstance()->getFoo(). This is
+  acceptable as a stepping stone, but should be replaced by proper injection
+  via a constructor argument. Do not however inject the MediaWikiServices
+  object!
+
+Migrate parameterized helper instantiation:
+Assume class Bar creates some helper object by calling new Foo( $x ),
+and Foo uses a global singleton of the Xyzzy service.
+* Define a FooFactory class (or a FooFactory interface along with a MyFooFactory
+  implementation). FooFactory defines the method newFoo( $x ) or getFoo( $x ),
+  depending on the desired semantics (newFoo would guarantee a fresh instance).
+  When Foo gets refactored to have Xyzzy injected, FooFactory will need a
+  Xyzzy instance, so newFoo() can pass it to new Foo().
+* Add an instantiator function for FooFactory into ServiceWiring.php and add a
+  getFooFactory() method to MediaWikiServices. Don't forget to add the
+  appropriate test cases in MediaWikiServicesTest.
+* The code in Bar that calls Foo's constructor should be changed to have a
+  FooFactory instance injected; Eventually, the only code that instantiates
+  Foo are implementations of FooFactory, and the only code that instantiates
+  FooFactory is the instantiator in ServiceWiring.php.
+* As an intermediate step, Bar's constructor could initialize the $fooFactory
+  member variable by calling MediaWikiServices::getInstance()->getFooFactory().
+  This is acceptable as a stepping stone, but should be replaced by proper
+  injection via a constructor argument. Do not however inject the
+  MediaWikiServices object!
+
+Migrate a handler registry:
+Assume class Bar calls FooRegistry::getFoo( $x ) to get a specialized Foo
+instance for handling $x.
+* Turn getFoo into a non-static method.
+* Add an instantiator function for FooRegistry into ServiceWiring.php and add
+  a getFooRegistry() method to MediaWikiServices. Don't forget to add the
+  appropriate test cases in MediaWikiServicesTest.
+* Change all code that calls FooRegistry::getFoo() statically to call this
+  method on a FooRegistry instance. That is, Bar would have a $fooRegistry
+  member, initialized from a constructor parameter.
+* As an intermediate step, Bar's constructor could initialize the $fooRegistry
+  member variable by calling MediaWikiServices::getInstance()->
+  getFooRegistry(). This is acceptable as a stepping stone, but should be
+  replaced by proper injection via a constructor argument. Do not however
+  inject the MediaWikiServices object!
+
+Migrate deferred service instantiation:
+Assume class Bar calls new Foo(), but only when needed, to avoid the cost of
+instantiating Foo().
+* Define a FooFactory interface and a MyFooFactory implementation of that
+  interface. FooFactory defines the method getFoo() with no parameters.
+* Precede as for the "parameterized helper instantiation" case described above.
+
+Migrate a class with only static methods:
+Assume Foo is a class with only static methods, such as frob(), which
+interacts with global state or system resources.
+* Introduce a FooService interface and a DefaultFoo implementation of that
+  interface. FooService contains the public methods defined by Foo.
+* Add an instantiator function for FooService into ServiceWiring.php and
+  add a getFooService() method to MediaWikiServices. Don't forget to
+  add the appropriate test cases in MediaWikiServicesTest.
+* Add a private static getFooService() method to Foo. That method just
+  calls MediaWikiServices::getInstance()->getFooService().
+* Make all methods in Foo delegate to the FooService returned by
+  getFooService(). That is, Foo::frob() would do self::getFooService()->frob().
+* Deprecate Foo. Inject a FooService into all code that calls methods
+  on Foo, and change any calls to static methods in foo to the methods
+  provided by the FooService interface.
+
+Migrate static hook handler functions (to allow unit testing):
+Assume MyExtHooks::onFoo is a static hook handler function that is called with
+the parameter $x; Further assume MyExt::onFoo needs service Bar, which is
+already known to MediaWikiServices (if not, see above).
+* Create a non-static doFoo( $x ) method in MyExtHooks that has the same
+  signature as onFoo( $x ). Move the code from onFoo() into doFoo(), replacing
+  any access to global or static variables with access to instance member
+  variables.
+* Add a constructor to MyExtHooks that takes a Bar service as a parameter.
+* Add a static method called newFromGlobalState() with no parameters. It should
+  just return new MyExtHooks( MediaWikiServices::getBar() ).
+* The original static handler method onFoo( $x ) is then implemented as
+  self::newFromGlobalState()->doFoo( $x ).
+
+Migrate a "smart record":
+Assume Thingy is a "smart record" that "knows" how to load and store itself.
+For this purpose, Thingy uses wfGetDB().
+* Create a "dumb" value class ThingyRecord that contains all the information
+  that Thingy represents (e.g. the information from a database row). The value
+  object should not know about any service.
+* Create a DAO-style service for loading and storing ThingyRecords, called
+  ThingyStore. It may be useful to split the interfaces for reading and
+  writing, with a single class implementing both interfaces, so we in the
+  end have the ThingyLookup and ThingyStore interfaces, and a SqlThingyStore
+  implementation.
+* Add instantiator functions for ThingyLookup and ThingyStore in
+  ServiceWiring.php. Since we want to use the same instance for both service
+  interfaces, the instantiator for ThingyLookup would return
+  $services->getThingyStore().
+* Add getThingyLookup() and getThingyStore methods to MediaWikiServices.
+  Don't forget to add the appropriate test cases in MediaWikiServicesTest.
+* In the old Thingy class, replace all member variables that represent the
+  record's data with a single ThingyRecord object.
+* In the old Thingy class, replace all calls to static methods or functions,
+  such as wfGetDB(), with calls to the appropriate services, such as
+  LoadBalancer::getConnection().
+* In Thingy's constructor, pull in any services needed, such as the
+  LoadBalancer, by using MediaWikiServices::getInstance(). These services
+  cannot be injected without changing the constructor signature, which
+  is often impractical for "smart records" that get instantiated directly
+  in many places in the code base.
+* Deprecate the old Thingy class. Replace all usages of it with one of the
+  three new classes: loading needs a ThingyLookup, storing needs a ThingyStore,
+  and reading data needs a ThingyRecord.
+
+Migrate lazy loading:
+Assume Thingy is a "smart record" as described above, but requires lazy loading
+of some or all the data it represents.
+* Instead of a plain object, define ThingyRecord to be an interface. Provide a
+  "simple" and "lazy" implementations, called SimpleThingyRecord and
+  LazyThingyRecord. LazyThingyRecord knows about some lower level storage
+  interface, like a LoadBalancer, and uses it to load information on demand.
+* Any direct instantiation of a ThingyRecord would use the SimpleThingyRecord
+  implementation.
+* SqlThingyStore however creates instances of LazyThingyRecord, and injects
+  whatever storage layer service LazyThingyRecord needs to perform lazy loading.

+The LinkCache class maintains a list of article titles and the information about
+whether or not the article exists in the database. This is used to mark up links
+when displaying a page. If the same link appears more than once on any page,
+then it only has to be looked up once. In most cases, link lookups are done in
+batches with the LinkBatch class, or the equivalent in Parser::replaceLinkHolders(),
+so the link cache is mostly useful for short snippets of parsed text (such as
+the site notice), and for links in the navigation areas of the skin.
+
+The link cache was formerly used to track links used in a document for the
+purposes of updating the link tables. This application is now deprecated.
+
+To create a batch, you can use the following code:
+
+$pages = array( 'Main Page', 'Project:Help', /* ... */ );
+$titles = array();
+
+foreach( $pages as $page ){
+	$titles[] = Title::newFromText( $page );
+}
+
+$batch = new LinkBatch( $titles );

+MediaWiki\Logger\LoggerFactory implements a PSR-3 [0] compatible message
+logging system.
+
+Named Psr\Log\LoggerInterface instances can be obtained from the
+MediaWiki\Logger\LoggerFactory::getInstance() static method.
+MediaWiki\Logger\LoggerFactory expects a class implementing the
+MediaWiki\Logger\Spi interface to act as a factory for new
+Psr\Log\LoggerInterface instances.
+
+The "Spi" in MediaWiki\Logger\Spi stands for "service provider interface". An
+SPI is an API intended to be implemented or extended by a third party. This
+software design pattern is intended to enable framework extension and
+replaceable components. It is specifically used in the
+MediaWiki\Logger\LoggerFactory service to allow alternate PSR-3 logging
+implementations to be easily integrated with MediaWiki.
+
+The service provider interface allows the backend logging library to be
+implemented in multiple ways. The $wgMWLoggerDefaultSpi global provides the
+classname of the default MediaWiki\Logger\Spi implementation to be loaded at
+runtime. This can either be the name of a class implementing the
+MediaWiki\Logger\Spi with a zero argument constructor or a callable that will
+return an MediaWiki\Logger\Spi instance. Alternately the
+MediaWiki\Logger\LoggerFactory::registerProvider() static method can be called
+to inject an MediaWiki\Logger\Spi instance into the LoggerFactory and bypass
+the use of the default configuration variable.
+
+The MediaWiki\Logger\LegacySpi class implements a service provider to generate
+MediaWiki\Logger\LegacyLogger instances. The MediaWiki\Logger\LegacyLogger
+class implements the PSR-3 logger interface and provides output and
+configuration equivalent to the historic logging output of wfDebug,
+wfDebugLog, wfLogDBError and wfErrorLog. The MediaWiki\Logger\LegacySpi class
+is the default service provider configured in DefaultSettings.php. It's usage
+should be transparent for users who are not ready or do not wish to switch to
+a alternate logging platform.
+
+The MediaWiki\Logger\MonologSpi class implements a service provider to
+generate Psr\Log\LoggerInterface instances that use the Monolog [1] logging
+library. See the PHP docs (or source) for MediaWiki\Logger\MonologSpi for
+details on the configuration of this provider. The default configuration
+installs a null handler that will silently discard all logging events. The
+documentation provided by the class describes a more feature rich logging
+configuration.

+
+Magic Words are some phrases used in the wikitext. They are used for two things:
+* Variables (like {{PAGENAME}}, {{SERVER}}, ...): part of wikitext, that looks
+  like templates but that don't accept any parameter.
+* Parser functions (like {{fullurl:...}}, {{#special:...}}): behaves like 
+  functions and accepts parameters.
+
+The localized arrays keys are the internal name, and the values are an array, 
+whose include their case-sensitivity and their alias forms. The first form 
+defined is used by the program, for example, when moving a page and its old name
+should include #REDIRECT.
+
+They can be added in several arrays:
+* By adding a file to $wgExtensionMessagesFiles and defining there $magicWords.
+  This array is associative with the language code in the first dimension key
+  and then a "normal" array of magic words.
+* Localized arrays (languages/messages/LanguageXX.php) include their different 
+  names to be used by the users.
+
+To add a new variable, you should use the "MagicWordwgVariableIDs" hook to add
+the internal name to the $magicWords array. You'll need to define the value of
+the variable with the "ParserGetVariableValueSwitch" hook.
+
+For example to add a new variable:
+
+Create a file called ExtensionName.i18n.magic.php with the following contents:
+----
+<?php
+
+$magicWords = array();
+
+$magicWords['en'] = array(
+	// Case sensitive.
+	'mag_custom' => array( 1, 'CUSTOM' ),
+);
+
+$magicWords['es'] = array(
+	'mag_custom' => array( 1, 'ADUANERO' ),
+);
+----
+
+$wgExtensionMessagesFiles['ExtensionNameMagic'] = __DIR__ . '/ExtensionName.i18n.magic.php';
+$wgHooks['MagicWordwgVariableIDs'][] = 'wfAddCustomMagicWordID';
+$wgHooks['ParserGetVariableValueSwitch'][] = 'wfGetCustomMagicWordValue';
+
+function wfAddCustomMagicWordID( &$magicWords ) {
+	$magicWords[] = 'mag_custom';
+	return true;
+}
+
+function wfGetCustomMagicWordValue( &$parser, &$varCache, &$index, &$ret ){
+	if( $index == 'mag_custom' ){
+		$ret = $varCache['mag_custom'] = "Custom value";
+	}
+	return true;
+}
+
+And to add a new parser function:
+
+Create a file called ExtensionName.i18n.magic.php with the following contents:
+----
+<?php
+
+$magicWords = array();
+
+$magicWords['en'] = array(
+	// Case insensitive.
+	'mag_custom' => array( 0, 'custom' ),
+);
+
+$magicWords['es'] = array(
+	'mag_custom' => array( 0, 'aduanero' ),
+);
+----
+
+$wgExtensionMessagesFiles['ExtensionNameMagic'] = __DIR__ . '/ExtensionName.i18n.magic.php';
+$wgHooks['ParserFirstCallInit'][] = 'wfRegisterCustomMagicWord';
+
+function wfRegisterCustomMagicWord( &$parser ){
+	$parser->setFunctionHook( 'mag_custom', 'wfGetCustomMagicWordValue' );
+	return true;
+}
+
+function wfGetCustomMagicWordValue( &$parser, $var1, $var2 ){
+	return "custom: var1 is $var1, var2 is $var2";
+}
+
+Note: the 'ParserFirstCallInit' hook is only available since 1.12. To work with
+an older version, you'll need to use an extension function.

+Prior to version 1.16, maintenance scripts were a hodgepodge of code that
+had no cohesion or formal method of action. Beginning in 1.16, maintenance
+scripts have been cleaned up to use a unified class.
+
+1. Directory structure
+2. How to run a script
+3. How to write your own
+
+1. DIRECTORY STRUCTURE
+  The /maintenance directory of a MediaWiki installation contains several
+subdirectories, all of which have unique purposes.
+
+2. HOW TO RUN A SCRIPT
+  Ridiculously simple, just call 'php someScript.php' that's in the top-
+level /maintenance directory.
+
+Example:
+  php clearCacheStats.php
+  
+The following parameters are available to all maintenance scripts
+--help   : Print a help message
+--quiet  : Quiet non-error output
+--dbuser : The database user to use for the script (if needed)
+--dbpass : Same as above (if needed)
+--conf   : Location of LocalSettings.php, if not default
+--wiki   : For specifying the wiki ID
+--batch-size : If the script supports batch operations, do this many per batch
+
+3. HOW TO WRITE YOUR OWN
+Make a file in the maintenance directory called myScript.php or something.
+In it, write the following:
+
+==BEGIN==
+
+<?php
+
+require_once 'Maintenance.php';
+
+class DemoMaint extends Maintenance {
+
+  public function __construct() {
+    parent::__construct();
+  }
+
+  public function execute() {
+  }
+}
+
+$maintClass = "DemoMaint";
+require_once RUN_MAINTENANCE_IF_MAIN;
+
+==END==
+
+That's it. In the execute() method, you have access to all of the normal
+MediaWiki functions, so you can get a DB connection, use the cache, etc.
+For full docs on the Maintenance class, see the auto-generated docs at
+https://doc.wikimedia.org/mediawiki-core/master/php/html/classMaintenance.html

+MediaWiki has optional support for memcached, a "high-performance,
+distributed memory object caching system". For general information
+on it, see: http://www.danga.com/memcached/
+
+Memcached is likely more trouble than a small site will need, but
+for a larger site with heavy load, like Wikipedia, it should help
+lighten the load on the database servers by caching data and objects
+in memory.
+
+== Installation ==
+
+Packages are available for Fedora, Debian, Ubuntu and probably other
+Linux distributions. If there's no package available for your
+distribution, you can compile it from source.
+
+== Compilation ==
+
+* PHP must be compiled with --enable-sockets
+
+* libevent: http://www.monkey.org/~provos/libevent/
+  (as of 2003-08-11, 0.7a is current)
+
+* optionally, epoll-rt patch for Linux kernel:
+  http://www.xmailserver.org/linux-patches/nio-improve.html
+
+* memcached: http://www.danga.com/memcached/download.bml
+  (as of this writing, 1.1.9 is current)
+
+Memcached and libevent are under BSD-style licenses.
+
+The server should run on Linux and other Unix-like systems... you
+can run multiple servers on one machine or on multiple machines on
+a network; storage can be distributed across multiple servers, and
+multiple web servers can use the same cache cluster.
+
+********************* W A R N I N G ! ! ! ! ! ***********************
+Memcached has no security or authentication. Please ensure that your
+server is appropriately firewalled, and that the port(s) used for
+memcached servers are not publicly accessible. Otherwise, anyone on
+the internet can put data into and read data from your cache.
+
+An attacker familiar with MediaWiki internals could use this to steal
+passwords and email addresses, or to make themselves a sysop and
+install malicious javascript on the site. There may be other types
+of vulnerability, no audit has been done -- so be safe and keep it
+behind a firewall.
+********************* W A R N I N G ! ! ! ! ! ***********************
+
+== Setup ==
+
+If you installed memcached using a distro, the daemon should be started
+automatically using /etc/init.d/memcached.
+
+To start the daemon manually, use something like:
+
+  memcached -d -l 127.0.0.1 -p 11211 -m 64
+
+(to run in daemon mode, accessible only via loopback interface,
+on port 11211, using up to 64MB of memory)
+
+In your LocalSettings.php file, set:
+
+	$wgMainCacheType = CACHE_MEMCACHED;
+	$wgMemCachedServers = array( "127.0.0.1:11211" );
+
+The wiki should then use memcached to cache various data. To use
+multiple servers (physically separate boxes or multiple caches
+on one machine on a large-memory x86 box), just add more items
+to the array. To increase the weight of a server (say, because
+it has twice the memory of the others and you want to spread
+usage evenly), make its entry a subarray:
+
+  $wgMemCachedServers = array(
+    "127.0.0.1:11211", # one gig on this box
+    array("192.168.0.1:11211", 2 ) # two gigs on the other box
+  );
+
+== PHP client for memcached ==
+
+MediaWiki uses a fork of Ryan T. Dean's pure-PHP memcached client.
+It also supports the PECL PHP extension for memcached.
+
+MediaWiki uses three object for object caching:
+* $wgMemc, controlled by $wgMainCacheType
+* $parserMemc, controlled by $wgParserCacheType
+* $messageMemc, controlled by $wgMessageCacheType
+If you set CACHE_NONE to one of the three control variable, (default
+value for $wgMainCacheType), MediaWiki still create a MemCacheClient,
+but requests to it are no-ops and we always fall through to the
+database. If the cache daemon can't be contacted, it should also
+disable itself fairly smoothly.
+
+By default, $wgMemc is used but when it is $parserMemc or $messageMemc
+this is mentioned below.
+
+== Keys used ==

+scripts.txt
+
+MediaWiki primary scripts are in the root directory of the software. Users
+should only use these scripts to access the wiki. There are also some .php that
+aren't primary scripts but helper files and won't work if they are accessed
+directly by the web.
+
+Primary scripts:
+
+  index.php
+    Main access point. It handles the most of requests.
+    See https://www.mediawiki.org/wiki/Manual:Index.php
+
+  api.php
+    Script to provide an API for bots to fetch content and informations about
+    the site and also modify it. See https://www.mediawiki.org/wiki/API
+    for more informations.
+
+  img_auth.php
+    Script that only serve images to logged in users. To configure the wiki
+    to use that script, see https://www.mediawiki.org/wiki/Manual:Image_Authorisation.
+
+  load.php
+    Used by ResourceLoader to serve minified, concatenated and gzipped CSS and JS.
+
+  opensearch_desc.php
+    Returns a OpenSearch description document (see http://www.opensearch.org/)
+    that points to the search engines of the wiki.
+
+  profileinfo.php
+    Allow users to see the profiling information that are stored in the
+    database.
+
+    To save the profiling information in the database (required to use this
+    script), you have to modify StartProfiler.php to use the Profiler class and
+    not the stub profiler which is enabled by default.
+    You will also need to set $wgProfiler['output'] to 'db' in LocalSettings.php
+    to force the profiler to save the informations in the database and apply the
+    maintenance/archives/patch-profiling.sql patch to the database.
+
+    To enable the profileinfo.php itself, you'll need to set $wgDBadminuser
+    and $wgDBadminpassword in your LocalSettings.php, as well as $wgEnableProfileInfo 
+    See also https://www.mediawiki.org/wiki/Manual:Profiling .
+
+  thumb.php
+    Script used to resize images if it is configured to be done when the web
+    browser requests the image and not when generating the page. This script can
+    be used as a 404 handler to generate image thumbs when they don't exist.
+
+There is also a file with a .php5 extension for each script. They can be used if

+This document describes the XML format used to represent information about external sites known
+to a MediaWiki installation. This information about external sites is used to allow "inter-wiki"
+links, cross-language navigation, as well as close integration via direct access to the other
+site's web API or even directly to their database.
+
+Lists of external sites can be imported and exported using the importSites.php and exportSites.php
+scripts. In the database, external sites are described by the sites and site_ids tables.
+
+The formal specification of the format used by importSites.php and exportSites.php can be found in
+the sitelist-1.0.xsd file. Below is an example and a brief description of what the individual XML
+elements and attributes mean:
+
+
+	<sites version="1.0">
+		<site>
+			<globalid>acme.com</globalid>
+			<localid type="interwiki">acme</localid>
+			<group>Vendor</group>
+			<path type="link">http://acme.com/</path>
+			<source>meta.wikimedia.org</source>
+		</site>
+		<site type="mediawiki">
+			<globalid>de.wikidik.example</globalid>
+			<localid type="equivalent">de</localid>
+			<group>Dictionary</group>
+			<forward/>
+			<path type="page_path">http://acme.com/</path>
+		</site>
+	</sites>
+
+
+The XML elements are used as follows:
+
+* sites: The root element, containing a set of site tags. May have a version attribute with the value 1.0.
+* site: A site entry, representing an external website. May have a type attribute with one of the following values:
+** ''unknown'': (default) any website
+** ''mediawiki'': A MediaWiki site
+* globalid: A unique identifier for the site. For a given site, the same unique global ID must be used across all wikis in a wiki farm (aka wiki family).
+* localid: An identifier for the site, for use on the local wiki. Multiple local IDs may be assigned to a given site. The same local ID can be used to refer to different sites by different wikis on the same farm/family. The localid element may have a type attribute with one of the following values:
+** interwiki: Used as an "interwiki" link prefix, for creating cross-wiki links.
+** equivalent: Used as a "language" link prefix, for cross-linking equivalent content in different languages.
+* group: The site group (e.g. wiki family) the site belongs to.
+* path: A URL template for accessing resources on the site. Several paths may be defined for a given site, for accessing different kinds of resources, identified by the type attribute, using one of the following values:
+** link: Generic URL template, often the document root.
+** page_path: (for mediawiki sites) URL template for wiki pages (corresponds to the target wiki's $wgArticlePath setting)
+** file_path: (for mediawiki sites) URL pattern for application entry points and resources (corresponds to the target wiki's $wgScriptPath setting).
+* forward: Whether using a prefix defined by a localid tag in the URL will cause the request to be redirected to the corresponding page on the target wiki (currently unused). E.g. whether http://wiki.acme.com/wiki/foo:Buzz should be forwarded to http://wiki.foo.com/read/Buzz. (CAVEAT: not yet implement, can be specified but has no effect)

+MediaWiki's SiteStore can be cached and stored in a flat file,
+in a json format. If the SiteStore is frequently accessed, the
+file cache may provide a performance benefit over a database
+store, even with memcached in front of it.
+
+Configuration:
+
+File-based caching can be enabled by setting $wgSitesCacheFile
+to the file path of the cache file.
+
+The file can then be generated with the rebuildSitesCache.php
+maintenance script.
+
+Format:
+
+In the sites cache file, sites are listed in a key-value
+map, with the key being the site's global id (e.g. "enwiki")
+and a key-value map as the value. The site list is wrapped
+with in a "sites" key.

+skin.txt
+
+MediaWiki includes four core skins:
+
+* Vector: The default skin. Introduced in the 1.16 release (2010), it has been
+  set as the default in MediaWiki since the 1.17 release (2011), replacing
+  Monobook.
+
+* Monobook: Named after the black-and-white photo of a book in the page
+  background. Introduced in the 2004 release of 1.3, it had been the
+  default skin since then, before being replaced by Vector.
+
+* Modern: An attractive blue/grey theme with sidebar and top bar. Derived from
+  Monobook.
+
+* Cologne Blue: A lightweight skin with minimal formatting. The oldest of the
+  currently bundled skins, largely rewritten in 2012 while keeping its
+  appearance.
+
+
+Several legacy skins were removed in the 1.22 release, as the burden of
+supporting them became too heavy to bear. Those were:
+
+* Standard (a.k.a. Classic): The old default skin written by Lee Crocker during
+  the phase 3 rewrite, in 2002.
+
+* Nostalgia: A skin which looks like Wikipedia did in its first year (2001).
+  This skin is now used for the old Wikipedia snapshot at
+  http://nostalgia.wikipedia.org/
+
+* Chick: A lightweight Monobook skin with no sidebar. The sidebar links were
+  given at the bottom of the page instead.
+
+* Simple: A lightweight skin with a simple white-background sidebar and no top
+  bar.
+
+* MySkin: Essentially Monobook without the CSS. The idea was that it could be
+  customised using user-specific or site-wide CSS (see below).
+
+
+== Custom CSS/JS ==
+
+It is possible to customise the site CSS and JavaScript without editing any
+server-side source files. This is done by editing some pages on the wiki:
+
+* [[MediaWiki:Common.css]] -- for skin-independent CSS
+* [[MediaWiki:Common.js]] -- for skin-independent JavaScript
+* [[MediaWiki:Vector.css]], [[MediaWiki:Monobook.css]], etc. -- for
+  skin-dependent CSS
+* [[MediaWiki:Vector.js]], [[MediaWiki:Monobook.js]], etc. -- for
+  skin-dependent JavaScript
+
+These can also be customised on a per-user basis, by editing
+[[User:<name>/vector.css]], [[User:<name>/vector.js]], etc.
+
+
+== Custom skins ==
+
+Several custom skins are available as of 2014.
+
+https://www.mediawiki.org/wiki/Category:All_skins
+
+Installing a skin requires adding its files in a subdirectory under skins/ and
+adding an appropriate require_once line to LocalSettings.php, similarly to how
+extensions are installed.
+
+You can then make that skin the default by adding:
+  $wgDefaultSkin = '<name>';
+
+Or disable it entirely by removing the require_once line. (User settings will
+not be lost if it's reenabled later.)
+
+See https://www.mediawiki.org/wiki/Manual:Skinning for more information on
+writing new skins.
+
+
+Until MediaWiki 1.25 it used to be possible to just put a <name>.php file in
+MediaWiki's skins/ directory, which would be loaded and expected to contain the
+Skin<name> class. This way has always been discouraged because of its limitations
+(inability to add localisation messages, ResourceLoader modules, etc.) and
+awkwardness in managing such skins. For information on migrating skins using
+this old method, see <https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery>.

+title.txt
+
+The MediaWiki software's "Title" class represents article titles, which are used
+for many purposes: as the human-readable text title of the article, in the URL
+used to access the article, the wikitext link to the article, the key into the
+article database, and so on. The class in instantiated from one of these forms
+and can be queried for the others, and for other attributes of the title. This
+is intended to be an immutable "value" class, so there are no mutator functions.
+
+To get a new instance, call Title::newFromText(). Once instantiated, the
+non-static accessor methods can be used, such as getText(), getDBkey(),
+getNamespace(), etc. Note that Title::newFromText() may return false if the text
+is illegal according to the rules below.
+
+The prefix rules: a title consists of an optional interwiki prefix (such as "m:"
+for meta or "de:" for German), followed by an optional namespace, followed by
+the remainder of the title. Both interwiki prefixes and namespace prefixes have
+the same rules: they contain only letters, digits, space, and underscore, must
+start with a letter, are case insensitive, and spaces and underscores are
+interchangeable. Prefixes end with a ":". A prefix is only recognized if it is
+one of those specifically allowed by the software. For example, "de:name" is a
+link to the article "name" in the German Wikipedia, because "de" is recognized
+as one of the allowable interwikis. The title "talk:name" is a link to the
+article "name" in the "talk" namespace of the current wiki, because "talk" is a
+recognized namespace. Both may be present, and if so, the interwiki must
+come first, for example, "m:talk:name". If a title begins with a colon as its
+first character, no prefixes are scanned for, and the colon is just removed.
+Note that because of these rules, it is possible to have articles with colons in
+their names. "E. Coli 0157:H7" is a valid title, as is "2001: A Space Odyssey",
+because "E. Coli 0157" and "2001" are not valid interwikis or namespaces.
+
+It is not possible to have an article whose bare name includes a namespace or
+interwiki prefix.
+
+An initial colon in a title listed in wiki text may however suppress special
+handling for interlanguage links, image links, and category links. It is also
+used to indicate the main namespace in template inclusions.
+
+Once prefixes have been stripped, the rest of the title processed this way:
+
+* Spaces and underscores are treated as equivalent and each  is converted to the
+  other in the appropriate context (underscore in URL and database keys, spaces
+  in plain text).
+* Multiple consecutive spaces are converted to a single space.
+* Leading or trailing space is removed.
+* If $wgCapitalLinks is enabled (the default), the first letter is  capitalised,
+  using the capitalisation function of the content language object.
+* The unicode characters LRM (U+200E) and RLM (U+200F) are silently stripped.
+* Invalid UTF-8 sequences or instances of the replacement character (U+FFFD) are
+  considered illegal.
+* A percent sign followed by two hexadecimal characters is illegal
+* Anything that looks like an XML/HTML character reference is illegal
+* Any character not matched by the $wgLegalTitleChars regex is illegal
+* Zero-length titles (after whitespace stripping) are illegal
+
+All titles except special pages must be less than 255 bytes when encoded with
+UTF-8, because that is the size of the database field. Special page titles may
+be up to 512 bytes.
+
+Note that Unicode Normal Form C (NFC) is enforced by MediaWiki's user interface
+input functions, and so titles will typically be in this form.
+
+getArticleID() needs some explanation: for "internal" articles, it should return
+the "page_id" field if the article exists, else it returns 0. For all external
+articles it returns 0. All of the IDs for all instances of Title created during
+a request are cached, so they can be looked up quickly while rendering wiki text
+with lots of internal links. See linkcache.txt.

+This page let you test the rendering font-family declaration for monospaced fonts. TODO: add some references here :-)
+</p>
+<p>
+Erwin Dokter had the following explanation on <a href="https://bugzilla.wikimedia.org/33496">Bugzilla #33496</a>:
+</p>
+<blockquote>
+By default, a (Windows) browser has it's default font-sizes set at 16px for
+serif and sans-serif, and 13px for monospace. Except in IE, where you cannot
+set any font-sizes... it uses 16px for all fonts.
+<br/>
+Vector has a base font-size of 0.8em, and most browsers *correctly* scale down
+all fonts, including the monospace font, accordingly. So monospace is shown at
+0.8 x 13px = 10px (which is perceived as 'too small'). But when you assign any
+font besides just "monospace", those browsers will no longer treat it as
+monospace and use 0.8 x 16px = 13px instead.
+</blockquote>
+<p>
+Below are various rendering:

+
+<pre style='
+font-family: monospace;'>
+font-family: monospace;
