Set the render ID for each parse stored into cache so that we are able
to identify a specific parse when there are dependencies (for example
in an edit based on that parse). This is recorded as a property added
to the ParserOutput, not the parent CacheTime interface. Even though
the render ID is /related/ to the CacheTime interface, CacheTime is
also used directly as a parser cache key, and the UUID should not be
part of the lookup key.
In general we are trying to move the location where these cache
properties are set as early as possible, so we check at each location
to ensure we don't overwrite a previously-set value. Eventually we
can convert most of these checks into assertions that the cache
properties have already been set (T350538). The primary location for
setting cache properties is the ContentRenderer.
Moved setting the revision timestamp into ContentRenderer as well, as
it was set along the same code paths. An extra parameter was added to
ContentRenderer::getParserOutput() to support this.
Added merge code to ParserOutput::mergeInternalMetaDataFrom() which
should ensure that cache time, revision, timestamp, and render id are
all set properly when multiple slots are combined together in MCR.
In order to ensure the render ID is set on all codepaths we needed to
plumb the GlobalIdGenerator service into ContentRenderer, ParserCache,
ParserCacheFactory, and RevisionOutputCache. Eventually (T350538) it
should only be necessary in the ContentRenderer.

Bug: T353920
Change-Id: Iaac7942aa77aee5ab525852ac5b41dd516ff13c9
The previous implementation was using an ad-hoc regular expression which
was matching inside the data-mw attribute of Parsoid output, eg:
<sup about="#mwt42" [...] typeof="mw:Extension/ref mw:Error" data-mw="{"name":"ref","attrs":{"name":"infobox_stats_ref_rail"},"body":{"html":"<style data-mw-deduplicate=\"TemplateStyles:r1133582631\" typeof=\"...">
After substitution, the <link> element inserted contained " instead of
" and so broke out of the attribute.
Instead use a proper HTML tokenizer (via wikimedia/remex-html) so that
we don't allow bogus matches inside attribute values.
To fix up tests:
* Don't deduplicate styles when parsing UX messages (also helps performance)
* Don't deduplicate styles in ContentHandler integration tests
* Don't deduplicate styles by default in parser tests
(unless explicit option is set)

Broadened the argument type to allow passing LinkTarget to:
* ParserOutput::addCategory()
* ParserOutput::addLanguageLink()
* ParserOutput::addLink()
* ParserOutput::addImage()
* ParserOutput::addTemplate()
This allows for a tighter interface with Parsoid's
ContentMetadataCollector class and avoids errors caused by passing the
wrong form of string title ("text" with spaces versus "dbkey" with
underscores).
There are a few performance problems remaining after this patch, which
only apply to use by Parsoid (not the legacy parser):
1. ::addLink() does inefficient db requests to fetch the page id for
each link if the optional $id parameter is not passed. These lookups
should be deferred and a LinkBatch used. (The legacy parser always
passes $id.)
2. ::addTemplate() similarly requires $page_id (and $rev_id) to be
passed, so is not currently usable by Parsoid.
3. ::addLanguageLink() uses Title::getFullText() which is not present
in LinkTarget and is currently implemented as a full Title lookup.
This is not an issue for the legacy parser, because it already has a
Title object so the lookup is a no-op, but could be improved for
Parsoid's use.
Bug: T296023
Change-Id: If21ec8563c8a619bdde7c0cb6534bb9009480a21
Pages that are fast to render can be omitted from the parser cache
to preserve disk space and cache write operations.
The threshold is configurable per namespace, so the tradeoff can
be evaluated based on different access patterns. For example, pages
that are accessed rarely, like file description pages on commons,
may have a high threshold configured, while pages that are read
frequently, like wikipedia articles, may be configured to be always
cached, using a 0 threshold.
Filtering is based on a time profile recorded in the ParserOutput.
A generic mechanism for capturing the timing profile is implemented
in the ContentHandler base class. Subclasses may implement a more
rigorous capture mechanism.

Change-Id: I38a6f3ef064f98f3ad6a7c60856b0248a94fe9ac
== Skin::wrapHTML ==
Skin::wrapHTML no longer has to perform any guessing of the
ParserOutput language. Nor does it have to special wiki pages vs
special pages in this regard. Yay, code removal.
== ImagePage ==
On URLs like /wiki/File:Example.jpg, the main output handler is
ImagePage::view. This calls the parent Article::view to handle most of
its output. Article::view obtains the ParserOptions, and then fetches
ParserOutput, and then adds `<div class=mw-parser-output>` and its
metadata to OutputPage.
Before this change, ImagePage::view was creating a wrapper based
on "predicting" what language the ParserOutput will contain. It
couldn't call the new OutputPage::getContentLanguage or some
equivalent as Article::view wouldn't have populated that yet.
This leaky abstraction is fixed by this change as now the `<div>`
from ParserOutput no longer comes with a "please wrap it properly"
contract that Article subclasses couldn't possibly implement correctly
(it coudln't wrap it after the fact because Article::view writes to
OutputPage directly).
RECENT (T310445):
A special case was recently added for file pages about translated SVGs.
For those, we decide which language to use for the "fullMedia" thumb
atop the page. This was recently changed as part of T310445 from a
hardcoded $wgLanguageCode (site content lang) to new problematic
Title::getPageViewLanguage, which tries to guestimate the page
language of the rendered ParserOutput and then gets the preferred
variant for the current user. The motivation for this was to support
language variants but used Title::getPageViewLanguage as a kitchen
sink to achieve that minor side-effect. The only part of this
now-deprecated method that we actually need is
LanguageConverter::getPreferredVariant().
Test plan: Covered by ImagePageTest.
== Skin mainpage-title ==
RECENT (T331095, T298715):
A special case was added to Skin::getTemplateData that powers the
mainpage-title interface message feature. This is empty by default,
but when created via MediaWiki:mainpage-title allows interface admins
to replace the H1 with a custom and localised page heading.
A few months ago, in Ifc9f0a7174, Title::getPageViewLanguage was
applied here to support language variants. Replace with the same
fix as for ImagePage. Revert back to Message::inContentLanguage()
but refactor to inLanguage() via MediaWikiServices::getContentLanguage
so that LanguageConverter::getPreferredVariant can be applied.
== EditPage ==
This was doing similar "predicting" of the ParserOutput language to
create an empty preview placeholder for use by preview.js. Now that
ApiParse (via ParserOutput::getText) returns a usable element without
any secret "you magically know the right class, lang, and dir" contract,
this placeholder is no longer needed.
Test Plan:
* EditPage: Default preview
1. index.php?title=Main_Page&action=edit
2. Show preview
3. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
* EditPage: JS preview
1. Preferences > Editing > Show preview without reload
2. index.php?title=Main_Page&action=edit
3. Show preview
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
5. Type something and 'Show preview' again
6. Assert old element gone, new text is shown, and new element
attributes are the same as the above.
== McrUndoAction ==
Same as EditPage basically, but without the JS preview use case.
== DifferenceEngine ==
Test:
1. Open /w/index.php?title=Main_Page&diff=0
(this shows the latest diff, can do manually by viewing
/wiki/Main_Page, click "View history", click "Compare selected revisions")
2. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
3. Open /w/index.php?title=Main_Page&diff=0&action=render
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
== Special:ExpandTemplates ==
Test:
1. /wiki/Special:ExpandTemplates
2. Write "Hello".
3. "OK"
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>

Provide a way for backend code to determine the primary language of a
ParserOutput, eg for setting the Content-Language header of an API
response.
This is read-only and backed by extension data at the moment for
transition purposes; if this API sticks we'll graduate it to a
"real" property in the future, with appropriate serialization
to/from JSON (T303329).
Similarly, this patch only includes the most basic code to handle
the various ParserOutput merge cases in
ParserOutput::merge{Internal,Html,Tracking}MetaDataFrom(),
ParserOutput::collectMetadata(), and
OutputPage::addParserOutput{Content,Metadata,Text,}(); mostly
inherited from the fact that the storage is backed by extension
data at the moment.
Generally only the "top-level" parser output gets to set the
primary language; we'll presumably need to ensure that the
language is consistent during merge.

* Rather than computing TOC HTML in Parser and setting it in
ParserOutput, compute it on demand based on section metadata.
This will let Parsoid set section metadata in ParserOutput
and have the TOC generated automatically.
* This required fixing some "bugs" in Linker's generateTOC
which didn't properly close tags and relied on Tidy to fix
up unclosed li and ul tags.
* This patch relies on converting section metadata objects to
array objects, but Linker::generateTOC could be converted to
use TOC data instead.
* Since TOC generation is now moved to getText(), this is done
post-PC load and this eliminates the parser cache split on
user language for TOC heading localization.

* ParserOutput::setSections()/::getSections() are expected
to be deprecated. Uses in extensions and skins will need to be
migrated in follow up patches once the new interface has stabilized.
* In the skins code, the metadata is converted back to an array.
Downstream skin TOC consumers will need to be migrated as well
before we can remove the toLegacy() conversion.
* Fixed SerializationTestTrait's validation method
- Not sure if this is overkill but should handle all future
complex objects we might stuff into the ParserCache.
* This patch emits a backward-compatible Sections property in order to
avoid changing the parser cache serialization format. T327439 has
been filed to eventually use the JsonCodec support for object
serialization, but for this initial patch it makes sense to avoid
the need for a concurrent ParserCache format migration by using a
backward-compatible serialization.
* TOCData is nullable because the intent is that
ParserOutput::setTOCData() is MW_MERGE_STRATEGY_WRITE_ONCE; that is,
only the top-level fragment composing a page will set the TOCData.
This will be enforced in the future via wfDeprecated() (T327429),
but again our first patch is as backward-compatible as possible.

Previously:
* It was unclear that generate-html is an optional optimization
* Most of MediaWiki core was doing $parserOutput->setText('') if
html wasn't generated. However this is wrong and will cause
$parserOutput->hasText() to return true and also potentially cause
cache pollution if a content handler both does that and supports
parser cache (Like MassMessage; see T299896)
* The default value of mText in the constructor was '', and most
of the time MW used that default. This doesn't seem right. If
setText() is never called, the ParserOutput should not be considered
to have text
* It was impossible to set mText to null, as $parserOutput->setText(null)
was a no-op. Docs implied you were supposed to do this, so it was very
confusing.
This patch clarifies docs, changes the default value for ParserOutput::$mText
from '' to null, and makes $parserOutput->setText(null) do what you
expect it to. The last two are arguably breaking changes, although
the previous behaviours were unexpected, mostly undocumented and
based on a code search do not appear to be relied on.
It seems like the main reason this only broke MassMessage is most
content handlers either don't support generateHtml, or they don't
support parser cache.

The old ParserOutput::getProperty() method returned `false` when a property
was missing. This requires callers to use the `?:` syntax to supply default
values, which then causes any falsey value to be treated as missing.
So, for example, setting the defaultsort to '0' will cause the default
sort to be ignored.
Modern php convention is to use `null` for missing values, and the `??`
syntax is a better/more restrictive alternative to `?:`.
We renamed `ParserOutput::getProperty()` to `::getPageProperty()` in
1.38 (Ie963eea5aa0f0e984ced7c4dfa0fd65d57313cfa/T287216) but kept the
return value convention. Before this actually makes it into a 1.38
release, take the opportunity to fix the return value for the new
`ParserOutput::getPageProperty()` method to return `null` when the
property is missing.
We need to do some temporary workarounds to the places we'd
already swapped over to use the new `::getPageProperty()` method
to allow them to handle either `false` or `null` as a return value;
we'll clean that up once this is merged.

There is a common and reasonable need for longer lines in tests.
The nudge for shorter lines doesn't seem valuable here. The natural
