Bartosz Dziewoński a6a547f2b2 Add some tests covering ThreadItem::getHTML() and related methods
* 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.

Bartosz Dziewoński 47510a22f3 EventDispatcher: Fix ignoring level 3+ headings
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.

Bartosz Dziewoński 8de8d80cde Deal with document body consistently
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.

Bartosz Dziewoński 80704b6e80 Test cases for interactions with events generated by base Echo
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).

C. Scott Ananian 25272e7a4a Don't refer directly to PHP dom extension classes; avoid nonstandard behavior
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.

C. Scott Ananian 5203d30ea6 Use DOMCompat::newDocument() to create a new Document
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.

Bartosz Dziewoński d0e4aeaecb Fix notifications when new comment is under subheading
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).

Bartosz Dziewoński 42ce942c86 Introduce comment "names" to identify comments across revisions/pages
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.

Bartosz Dziewoński 5a07139249 CommentFormatterTest: Avoid re-serializing the HTML
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.

Bartosz Dziewoński 1c3fada1fb Make CommentUtilsTest a proper unit test
Documentation:
https://www.mediawiki.org/wiki/Manual:PHP_unit_testing/Writing_unit_tests_for_extensions#Two_types_of_tests

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

Bartosz Dziewoński 8f42c74985 Fix skipping to the end of paragraph, now it considers nested tags
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>).

Ed Sanders 7b2448d2f0 Use DOMCompat::getOuterHTML instead of doc->saveHTML()
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").

Bartosz Dziewoński ccd9e411d2 Allow updating the expected results when running PHP tests
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
  inconsistencies between the previous expected outputs and the actual
  outputs.
