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.

* ThreadItem::getHTML (may soon be used in API)
* CommentItem::getBodyHTML (may soon be used in API)

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.

Use `DOMCompat::getBody( ... )` as a nicer getter than
`->getElementsByTagName( 'body' )->item( 0 )`.
Remove overly defensive checks and redundant annotations on its

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.

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,

Also, we recently learned that the precise format matters here
(T274709), and now this test *actually* covers the fix for that bug.

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

0.35s, compared to 1.1s before.

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>).

The latter results in lots of extra HTML entity encoding.
The former is built by the Parsing team and appears to result
in no unexpected changes elsewhere in the document.
As Parsoid's selser relies on HTML fragments being byte-for-byte
equal, these changes were resulting in wikitext normalisations
in untouched parts of the document ("dirty diffs").

This is similar to the code we already have in JS tests, but instead
of printing to the console where you have to copy-paste from, it just
overwrites the files.
Also, update all of the expected results by this method.
Changes in the expected outputs:
* In JSON files, the "warnings" are now always in the same place
regardless of the type of the warning.
* In all HTML files, self-closing tags now include the trailing slash,
some characters are no longer encoded as entities when not necessary,
and attributes may be single-quoted when that makes them shorter.
* In Parsoid HTML files, the header is no longer terribly mangled.
Other notes:
* CommentParserTest.php: Change the output of serializeComments()
to be in similar order as in JS, to reduce the diffs in this commit
and because it's a better order for humans.
* modifier.test.js: Remove some hacks that were working around small

In JS, strings are internally encoded as UTF-16, and properties like
.length return values in UTF-16 code units.
In PHP, strings are internally encoded as UTF-8, and we have the
option of using methods that return bytes like strlen() or UTF-8 code
units like mb_strlen().
However, the values produced by preg_match( …, PREG_OFFSET_CAPTURE )
are in bytes, and there's nothing we can do about that. So let's use
bytes throughout, mixing the two types results in meaningless numbers.
Then in the test code, we have to calculate UTF-16 code units offsets
based on the UTF-8 byte offsets.
We also have to copy the entire workaround for mw:Entity nodes… Maybe
the parser should be fixed to return the real nodes for ranges' ends
in this case.

We can calculate the child's index in its parent by counting its
