Bartosz Dziewoński 8e44b43df0 Split off ThreadItemSet from CommentParser
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.

Bartosz Dziewoński 4613ae78e7 Change CommentParser into a service
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.

Bartosz Dziewoński ae9f26a9e5 Various code quality tweaks
(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.

Bartosz Dziewoński c1f4668806 Change CommentParser and ImmutableRange to use offsets in codepoints instead of bytes
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.

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.

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.

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 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

But the previous several commits also caused changes in just about all
of the test data, so we might as well do this too.

Bartosz Dziewoński 375bfe028e parser: Fix comment ranges when timestamp has entities
Previously, parser would output offsets that don't exist in their

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.
