Previously, we required a signature at the end of the comment.
This was a pretty rough heuristic that did not correctly handle
many comments that we would consider entirely properly signed
in CommentParser (e.g. comments wrapped in formatting like
<small>…</small>, comments with a post-scriptum or in parentheses,
or comments generated by various templates).
Now we process the user input using the same code that adds reply
links, and only add a signature when we detect that there really
isn't a signature (including template-generated), or if the signature
is in the wrong place and would result in the reply link showing up
in the wrong place as well (not at the end of the comment).

Goal:
-----
Finishing the work from Iadb7757debe000025e52770ca51ebcf24ca8ee66
by changing CommentParser::parse() to return a data object, instead of
the whole parser.
Changes:
--------
ThreadItemSet.php:
ThreadItemSet.js:
* New data class to access the results of parsing a discussion. Most
methods and properties are moved from CommentParser with no changes.
CommentParser.php:
Parser.js:
* parse() returns a new ThreadItemSet.
* Remove methods moved to ThreadItemSet.
* Placeholder headings are generated slightly differently, as we process
things in a different order.
* Grouping threads and computing IDs/names is no longer lazy. We always
needed IDs/names anyway.
* computeId() explicitly uses a ThreadItemSet to check the existing IDs
when de-duplicating.
controller.js:
* Move the code for turning some nodes annotated by CommentFormatter
into a ThreadItemSet (previously a Parser) from controller#init to
ThreadItemSet.static.newFromAnnotatedNodes, and rewrite it to handle
assigning parents/replies and recalculating legacy IDs more nicely.
* mw.dt.pageThreads is now a ThreadItemSet.

Goal:
-----
To have a method like CommentParser::parse(), which just takes a node
to parse and a title and returns plain data, so that we don't need to
keep track of the config to construct a CommentParser object (the
required config like content language is provided by services) and
we don't need to keep that object around after parsing.
Changes:
--------
CommentParser.php:
* …is now a service. Constructor only takes services as arguments.
The node and title are passed to a new parse() method.
* parse() should return plain data, but I split this part to a separate
patch for ease of review: I49bfe019aa460651447fd383f73eafa9d7180a92.
* CommentParser still cheats and accesses global state in a few places,
e.g. calling Title::makeTitleSafe or CommentUtils::getTitleFromUrl,
so we can't turn its tests into true unit tests. This work is left
for future commits.
LanguageData.php:
* …is now a service, instead of a static class.
Parser.js:
* …is not a real service, but it's changed to behave in a similar way.
Constructor takes only the required config as argument,
and node and title are instead passed to a new parse() method.
CommentParserTest.php:
parser.test.js:
* Can be simplified, now that we don't need a useless node and title
to test internal methods that don't use them.
testUtils.js:
* Can be simplified, now that we don't need to override internal
ResourceLoader stuff just to change the parser config.

The Data class contained utilities for two unrelated purposes.
Split each half to a separate class.
Notably, this improves the signature of the getLocalData() function.

(suggested by PhpStorm)
composer.json:
* Document required PHP extensions
Parser.js:
* Remove incorrect param documentation
* Fix some typos in comments (missing parentheses)
CommentParser.php:
* Fix some typos in comments (missing parentheses)
ImmutableRange.php:
* Remove unused property
* Add a `throw` to indicate that code path is unreachable
SubscribedNewCommentPresentationModel.php:
* Add missing `return false`
CommentParserTest.php:
* Remove unnecessary pass-by-reference
CommentModifierTest.php:
* Remove unused variable
CommentParserTest.php:
* Don't construct Element objects directly. PHP's DOMElement allows
it, but Parsoid/Dodo's doesn't, and we use the latter for static
analysis. This generates all kinds of confusing warnings.

The PHP DOM extension measures lengths and offsets in Unicode codepoints.
Our PHP code used UTF-8 bytes, causing some offsets to be slightly off.
Now it mostly uses Unicode codepoints as well (we're forced to use bytes
in a few places, because preg_match returns offsets in bytes).
In practice, this had no visible effect to the user. It caused the
markers `<span data-mw-comment-end="..."></span>` to be placed at
the end of their container instead of the correct position when the
timestamp contained multibyte characters (e.g. "ź" in Polish); but
the correct position is usually at the end of the container anyway.
In the test cases, the only difference is placing these markers before
a trailing line break inside `<p>...</p>` tags rather than before it.
The patch also accidentally fixes another bug, where element nodes
with no children (mostly <img>) were incorrectly excluded when calling
cloneContents(), because they were treated as if they were text nodes.
Change-Id: Iccdccf1078598f4b62cab96225e9c85a4c0e93ee
* ThreadItem::getText
* CommentItem::getBodyText (used when generating notifications)
* ThreadItem::getHTML (may soon be used in API)
* CommentItem::getBodyHTML (may soon be used in API)
* ImmutableRange::cloneContents (the common implementation for all
of the above)
The outputs are only lightly reviewed. This is mostly meant to
document the current behavior rather than the expected behavior,
to avoid making unintentional changes while refactoring.

The code (prior to d25825a754) assumed
that level 3+ headings would always follow a level 2 heading or the
placeholder heading, but we don't generate a placeholder heading if
there are no comments in section zero.
Add more tests to confirm that comments under level 3+ headings (that
are not sub-headings of level 2), and level 1 headings, are ignored
when generating notifications, and do not mess with normal headings.

This DOMDocument property has no effect, because we do not use
DOMDocument methods for parsing HTML, but rather DOMUtils::parseHTML()
provided by Parsoid.

Use `DOMCompat::getBody( ... )` as a nicer getter than
`->getElementsByTagName( 'body' )->item( 0 )`.
Remove overly defensive checks and redundant annotations on its
return value. Since we're dealing with HTML documents throughout,
the document body is guaranteed to exist.
We previously needed some of them to convince Phan when it thought
the body may be null, but this seems to no longer be needed.

Adding test cases in a separate commit to make it easier to review how
the test results change after I98fbca8e.
* For mentions, the 'mentioned-users' extra parameter is copied to our
event (which is then used to avoid duplicate notifications).
* For user talk page edit, nothing special happens right now (we use
the target page title to avoid duplicate notifications, but this is
not apparent from the test case, since page titles are not present).

These changes ensure that DiscussionTools is independent of DOM
library choice, and will not break if/when Parsoid switches to an
alternate (more standards-compliant) DOM library.
We run `phan` against the Dodo standards-compliant DOM library,
so this ends up flagging uses of non-standard PHP extensions to
the DOM. These will be suppressed for now with a "Nonstandard DOM"
comment that can be grepped for, since they will eventually
will need to be rewritten or worked around.
Most frequent issues:
* Node::nodeValue and Node::textContent and Element::getAttribute()
can return null in a spec-compliant implementation. Add `?? ''` to
make spec-compliant results consistent w/ what PHP returns.
* DOMXPath doesn't accept anything except DOMDocument. These uses
should be replaced with DOMCompat::querySelectorAll() or similar
(which end up using DOMXPath under the covers for DOMDocument any way,
but are implemented more efficiently in a spec-compliant
implementation).
* A couple of times we have code like:
`while ($node->firstChild!==null) { $node = $node->firstChild; }`
and phan's analysis isn't strong enough to determine that $node is still
non-null after the while. This same issue should appear with DOMDocument
but phan doesn't complain for some reason.
One apparently legit issue:
* Node::insertBefore() is once called in a funny way which leans on
the fact that the second option is optional in PHP. This seems to be
a workaround for an ancient PHP bug, and can probably be safely
removed.

Change-Id: I3c4f41c3819770f85d68157c9f690d650b7266a3
For compatibility with Parsoid's document abstraction (Parsoid may
switch to an alternate DOM library in the future), don't explicitly
create a new document object using `new DOMDocument`; instead use
the Parsoid wrapper `DOMCompat::newDocument()`. This ensures that
the Document object created will be compatible with Parsoid.
There are a number of other subtle dependencies on the PHP `dom`
extension in DiscussionTools, like explicit `instanceof` tests; those
will be tweaked in a follow-up patch
(I3c4f41c3819770f85d68157c9f690d650b7266a3) since they do not affect
correctness so long as Parsoid is aliasing Document to a subclass of
the built-in DOMDocument. Similarly, the Phan warnings we suppress
do not cause runtime errors (because of the fixes included in
c5265341afd9efde6b54ba56dc009aab88eff83c) but phan will be happier
once the follow-up patch lands and aligns all the DOM types.

The user interface only allows you to subscribe to level 2 headings.
But we would generate events for whatever heading was the closest,
If it was e.g. level 3, no one would receive that notification.
Now we generate events for the closest level 2 heading, or we don't
generate the event at all if there isn't one (if the only headings are
of level 3 and below, or level 1, or if the comment is added before
the first heading on the page).

The existing comment IDs can't be used to find the same comment on
a different revision or page (when it's transcluded), because they
depend on the comment's parent and its position on the page.
Comment names depend only on the author and timestamp. The trade-off
is that they can't distinguish comments posted within the same minute,
or in the same edit, so we will still need the IDs sometimes.
Prefer using comment names when replying, if they're not ambiguous.
This fixes T273413 and T275821.
Heading names depend on the author and timestamp of the oldest comment.
This way we don't have to detect changes to the heading text, but we
can't distinguish headings without any comments.

The code we're testing already produces a string of serialized HTML,
no need to parse and re-serialize it.
Also, we recently learned that the precise format matters here
(T274709), and now this test *actually* covers the fix for that bug.
Follow-up to 5b26e9664b.
As a downside, this test might now spuriously fail if the format of
the output of Parsoid's XMLSerializer changes. Hopefully that won't
happen too often.

We can do this because the tested methods do not depend on any globals
or on MediaWiki being installed.
In addition to being the new hotness, MediaWikiUnitTestCase allows the
test classes that use it instead of MediaWikiTestCase to start up much
faster. In my testing, running this test case individually now takes
0.35s, compared to 1.1s before.
Try:
* With new code:

* With old code:

Add yet another tree walking utility: CommentUtils::linearWalk().
Unlike TreeWalker, it allows handling the beginnings and ends of nodes
separately – kind of like parsing a XML token stream, or kind of like
VisualEditor's linear model.
(Add unit tests for this utility. The simple.html test case is copied
from [VisualEditor/VisualEditor]/demos/ve/pages/simple.html.)
Use this utility to stop skipping when we reach either a closing or
opening block node tag. Previously we'd skip over such tags inside
nested "transparent" nodes (like <a>, <del>, or apparently <font>).
