and check for this in WikiPage::doEditUpdates before
inserting a new CategoryMembershipChangeJob.
Some content models like the Wikibase ones do not
have categories and it's wasteful to add these jobs
for all Wikibase edits.

Avoid polluting the parser cache with skin-dependent output from
Skin::doEditSectionLink() by introducing getRawText(), which provides
access to the uncooked text. Use this in
WikitextContent::fillParserOutput() which is the primary offender
judging by the debug logs (see referenced bug).

I was initially going to refactor out the error message into Import.php,
but it quickly became apparent that WikiImporter's error handling needs a
LOT of work. In particular, to localise the error message into the user's
language is sadly non-trivial.
Although not used currently, the MWUnknownContentModelException subclass
will help with error handling improvements in the future.

When a JavaScript page is moved, a "redirect" in the form of
mw.loader.load(...) will be left behind, so any other
JavaScript loading the page that way will still work, albeit
with an extra HTTP request.
This also implements Content::getRedirectTarget(), so redirects
are marked properly in the database, and users viewing them
are redirected properly. A magic "/* #REDIRECT */" comment
must be in front of the mw.loader.load call. This is done so
that pages which currently are just one mw.loader.load call
aren't turned into redirects.

Special:ChangeContentModel allows for users with the 'editcontentmodel'
right to change the content model of a page.
Visiting Special:ChangeContentModel will contain an input field for a
page title. The user will then be sent to
Special:ChangeContentModel?pagetitle=<input> where the page title is
read only, with a content model selector and optional reason field.
The special page only allows converting between content models that
extend TextContent for simplicity. Advanced conversions should be done
via the API.
All content model changes via the special page or API generate a null
revision in the page history and a log entry at
Special:Log/contentmodel. The log entry has a revert link for
convenience (like the move log).

'isParserCachedUsed' implies that the parser cache usage has already occurred,
and obscures the true purpose of this method, which is to determine whether or
not the requested page *should* be looked up in the parser cache.
Only usage in extensions is in TextExtracts, which I changed to be both
backward- and forward-compatible in If5d5da8eab13.

Additionally, some uses of @ were replaced due to composer's autoloader

This adds supportsDirectApiEditing and
supportsDirectEditing methods to ContentHandler. Both
return false by default for the ContentHandler base
class, and true for TextContentHandler and it's
derivatives. (everything in core)
Extension content types that directly extend
AbstractContent / ContentHandler, often / generally don't
support direct editing. EntityContent in Wikibase
and Flow boards are the two such content types currently
in gerrit-hosted extensions.
The use and direct settings of the allowNonTextContent
member variable is replaced by enableApiEditOverride and
a setter for that. The only place allowNonTextContent is
used in all of Wikimedia-hosted git repos is core itself
(EditPage and ApiEditPage), so should be safe to make
this change.
With this change, Wikibase can remove its ApiCheckCanExecute
hook handler that disallows editing there, and MobileFrontend
could check if direct editing is allowed before enabling it's
editing features, instead of Wikibase having to add
MobileFrontend hook handlers to disable the features.

This is a hard deprecation, with getSecondaryDataUpdates returning an
empty array and addSecondaryDataUpdate throwing an exception. This seems
prudent since there are no known users of these methods, and they
interfere with the parser cache:
DataUpdates are basically jobs, they need access to services to
function. That makes them inherently non-serializable. This interferes
with the function of the parser cache, which serializes ParserOutput
objects in order to persist them.
This could be solved by splitting DataUpdates into DataUpdateDefinitions
and DataUpdateHandlers, similar to how JobSpecification works with
wgJobClasses. That however seems pointless and overkill, since
ParserOutput already has a mechanism for storing arbitrary data,
including any info needed by an UpdateJob: the setExtensionData method.
After this change, the preferred method to introduce custom data updates
is to store any relevant data using setExtensionData and
implement Content::getSecondaryDataUpdates() if possible. If not,
use the 'SecondaryDataUpdates' hook to construct the necessary update
objects from the info stored using setExtensionData.

Follows-up d2a82fcb60. These issues weren't previously exposed
as nothing uses JsonContent by default in core, and the extensions
using it (e.g. EventLogging) lock it down very early. As are
most of these methods were never really put to use (they were
called after the extension does its superset of checking, or
too early and WikiPage ignores it).
Bug fixes
* Empty JSON object was converted to an array by PST conversion.
The beautifyJSON method is intended for prettify purposes but
actually modified the content stored in the database and made
it no longer roundtrip ({} != []).
We can't change getJsonData to return an object since it's
a public method and people use it as an array. So we can't cast
it to a PHP object as that would break back-compat.
Turns out the class doesn't even support non-objects anyway (a
primitive in JSON can trivially cause a fatal as it wasn't
consistently considered invalid, though it didn't actually fatal
due to some lucky spaghetti code in WikiPage).
* Fix beautifyJSON by checking for empty objects to prevent
implicit {} to [] conversion.
* Add isValid() check to fillParserOutput() as it's called early
on. Otherwise it throws a warning that 'foreach' (in objectTable)
iterates over null. In practice it doesn't matter since the
entire parser output is rejected when WikiPage eventually
checks isValid (through Content::prepareSave).
* Consider all non- (PHP) array values invalid instead of just
non-null values.
Enhancements
* Display message "Empty object" instead of a completely blank page
for an empty object.
* Display message "Empty object" or "Empty array" instead of an
empty table cell.
* Render arrays as a list of values (without indices).
* Remove italics from table cells for values. The monospace font
should be enough. It also offsets it from the "Empty"
placeholders (which are italicised).
Refactoring and clean up
* Use FormatJson::parse so that we can use Status to distinguish
between null parse result and thus reliably cache it.
Ideally we wouldn't need to cache it, but right now this code
is pulled apart and called in so many strange ways that we end
up calling this several times.
* Improve fairly meaningless test (testBeautifyJson) that was
calling FormatJson in its data provider, exactly what the method
being tested did. It also provided the test with data that could
never end up in normal usage (a PHP-style associated array with
implied numerical indices).
* Document that this class rejects non-array values.
* Document the problem with WikiPage assumming PST can run on any
content. WikiPage fundamentally still assumes wikitext, in that
there's no concept of invalid content.
* Fix incorrect documentation for getJsonData's return value
(It may return null.)
* Fix incorrect documentation for beautifyJSON's return value.
(It never returned boolean.)

The new Extension:WikEdDiff is a custom inline difference engine.
There is currently no hook to integrate custom difference engines.
This patch adds a new hook called 'GetDifferenceEngine' in
/includes/content/ContentHandler.php in function
'createDifferenceEngine()'.
Passed variables:
$context: IContextSource context to be used for diff
$old: Revision ID to show and diff with
$new: Either a revision ID or one of the strings 'cur', 'prev' or 'next'
$refreshCache: If set, refreshes the diff cache
$unhide: If set, allow viewing deleted revs
&$differenceEngine: output parameter, difference engine object to be used
for diff
If the hook handler returns false, a valid difference engine object is
returned in the passed-by-reference variable $differenceEngine.
If the handler returns true, the default engine is used as fallback.
The specified diff engine class will typically be an extension of the
class DifferenceEngine (includes/diff/DifferenceEngine.php) with
modifications, e.g. of function generateTextDiffBody() and
__construct() (without deprecated parameter $rcid).
Also fixes a missing declaration in DifferenceEngine that is required for
extending this class.

This hook is the counterpart of ContentGetParserOutput: it gives
high-level access to the parsing of a content object (as opposed
to lower-level parser hooks like ParserBefore*/ParserAfter* which
are called for all kinds of non-content input like interface
messages and don't have the necessary context to know what kind of
input is being parsed), but it is called when the parsing has
already finished.
The intention is to provide a convenient location for ParserOutput
modifications which depend on some global property of the parsed
content, but need to happen before LinksUpdate. Currently there are
no hooks between parsing (initiated by WikiPage::doEditUpdates()
calling WikiPage::prepareContentForEdit()) and updating the link
tables (initiated by the same method calling
Content::getSecondaryDataUpdates()), so any hook an extension would
try to use would face one of the following problems:
* the parsing output is not available yet
* LinksUpdate has run already, modifying list properties is unsafe
* there is not enough context to tell what's being parsed
A typical use of this hook would be to add tracking categories when
something is missing from the text (e.g. there are no references).
For the concrete use case, see I43ed79b6a54cd31820ecae8139e29c5880f5dd1b
Alternative approaches that have been suggested and do not require
a new hook but are not robust / do not rely on a clear contract:
* use ParserAfterTidy or a similar hook, assume that the input
being parsed is the main page content iff limit reporting is
enabled
* use ParserAfterTidy or a similar hook, assume that the input
being parsed is the main page content iff
ParserOptions::getInterfaceMessage() is false (this would yield
some false positives, but in those cases adding a tracking
category would probably have no effect)

Since Id44d566a, the text passed to the parser when parsing a

Currently the names of associated Content classes are hardcoded,
meaning that any extension that wishes to subclass these implementations
must also re-implement that function, usually copying it exactly
with just the class name changed. Using "static" avoids that issue.
For ContentHandlers, I added a TextContentHandler::getContentClass,
which should be used when creating new Content objects.
