Ed Sanders d59d5e14f9 CommentFormatter: Escape user input in generated comment
Currently the only user input in a headingItem name is the username
which can't contain a '>', so the regex can't break, but this is
fragile, and we should always do our own escaping.

The HeadingItem's name is now present in the DOM, so just traverse
to it and use that instead.

Phan can analyze them now and reports some issues with types.

* Add some assertions on types where we're sure that we're using an
  Element or non-null, but Phan can't prove it
* Fix incorrect type hints on getFullyCoveredSiblings() and
  getCoveredSiblings(), luckily it was harmless

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 492dbd7847 Fix inserting comment start markers when they're outside of any wrappers
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.

Bartosz Dziewoński 90283b3a7e Update the [subscribe] buttons when auto-subscriptions are added
When our interface initialized on a page that the current user
recently edited (using the reply tool, the full-page source editor,
or any other way), check if any new automatic topic subscriptions
were added and update the interface to reflect that.

This requires doing some API requests after the page is loaded,
because adding auto-subscriptions happens asynchronously in a
DeferredUpdate (potentially after the user is already viewing
the page with their comment saved), and depends on the contents
of the edit.

(When using the reply tool, we could avoid this API request and
replicate the logic, but that's not implemented in this commit
to keep it simple.)

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.

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 5b26e9664b CommentFormatter: Fix inserting placeholder heading marker
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
6c7a0ca9a2.

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.

Bartosz Dziewoński 9ee0fd69f5 Allow headings to have IDs
Previously, only comments could have IDs, because we only needed IDs
for replying. But we might also use them for notifications soon.

Bartosz Dziewoński 6719d17364 Handle cached "legacy" IDs (and other JSON-serialized data)
The output of CommentFormatter::addReplyLinks() and consequently
ThreadItem::jsonSerialize() can end up in the HTTP cache (Varnish) on
Wikimedia wikis. We need to consider that when changing that code.

Introduce a concept of legacy ID (generated by the older algorithm
after it changes), add some placeholder code that will generate them
in the future, and update some code to find comments by either normal
or legacy IDs.

Add dire comments in a bunch of places (as if that ever helps).
