For comments posted on or after 2022-07-12 (configurable), use a
shorter format, identical to the timestamps MediaWiki uses in URLs.
Changing the format for already existing comments would involve
difficult migrations, therefore we elect not to do it.

Since times immemorial, and for reasons lost to history, our test code
was adding an extra <div> wrapper before parsing the HTML used for
tests. This wasn't a problem, until now, because I want to add some
tests for T303396 that need to check that the *real* wrappers present
in some test cases are handled correctly.
Changes to test cases mostly remove a leading "0/" from serialized

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).

We were rendering the preview in a completely different way from how
we would add the real reply, and the results would be different
sometimes, particularly for multi-line comments with messed-up markup.
Render it server-side instead, in a very similar way to real replies
(generating a DOM list node and transforming it through Parsoid),
although without the whole context of the page to improve performance.
We can remove a lot of client-side code that was used solely for this.
This will allow the preview to accurately display the signatures when
we change how they are added (T278442), without us having to implement
those changes again from scratch for the preview.

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.

It adds white-space between block tags and strips invisible tags.
It may be slightly slower (it takes HTML as input rather than DOM, so
we need to serialize the HTML first and then call it, rather than only
find and concatenate text nodes), but the difference is negligible,
and it seems better to use this method than to try to re-implement it.

Comment boundaries are stored as a DOM parent node plus a child index.
Because of that, inserting anything into the DOM before a comment –
such as another comment's start/end markers – would cause us to insert
subsequent comments' markers into the wrong places.
This issue didn't affect many pages, because usually any parent node
would have just one comment in it. Only pages with comment boundaries
outside of any wrappers (directly inside the root node) were broken.
Just process the list in reverse to fix this.

Usually this isn't a problem, because the comments are marked as
template-generated and we don't allow replying to them. But we had a

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.

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.

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.

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

The issue occurred when replying to a comment consisting of multiple
list items, starting with a <dt> (instead of the expected <dd>), so
that the comment is considered to be unindented.
Modifier tried to add the reply directly inside the list (<dl>) rather
than inside the last list item (<dt>), which caused it to be confused
about indentation levels and try to un-indent more times than there
were indentations.
The simplest solution, given the existing code, is to add the reply
outside the list instead, in a new list. This results in a "list gap"
(<dl><dt>...</dt><dd>...</dd></dl><dl><dd>...</dd></dl>), but I think
it's acceptable for this rare case.
There are separate tests cases for old Parser and for Parsoid HTML,
because they parse the original wikitext differently (with the old
Parser producing HTML with a list gap too).

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

This code expected $container->firstChild to be a
<div class="mw-parser-output">, but that element is not present
when we're running on HTML to be saved in parser cache.
We ended up inserting the marker inside whatever node was the
first on the page, and if it was a <style> element, both our
marker and the styles would be lost when serializing, like in

When we're running on final HTML, the marker will now be outside
of <div class="mw-parser-output">, but that seems to be fine. Only
early versions of I4e60fdbc098c1a74757d6e60fec6bcf8e5db37c1 had
problems with that (see comments on patchset 41), but it works now.
The added test case also covers the fix for T274709.

Top-level comments that start or end with a list (inconsistent
indentation) would not have triggered the logic for detecting
wrappers.

For a moment I doubted if we handle this case correctly, but in fact
I didn't botch that code *this* badly.

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:
time php tests/phpunit/phpunit.php extensions/DiscussionTools/tests/phpunit/unit/CommentUtilsTest.php
* With old code:
time php tests/phpunit/phpunit.php extensions/DiscussionTools/tests/phpunit/CommentUtilsTest.php

* Ignore rendering-transparent nodes between discussion comments.
* Improve isRenderingTransparentNode() so that <link> nodes
representing TemplateStyles are not considered transparent,
otherwise this would undo ae920b831f.

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>).
