The most common case of edit conflicts on talk pages is several people
responding to the same comment at the same time.[citation needed]
We can easily resolve this case by fetching the latest revision of the
page and re-running our code to insert a reply on it.
When we can't insert a reply, that probably means the parent comment
was deleted or moved, so display an error message indicating that
instead of the generic one.

Previously, we only built the Parsoid document once (on page load) and
kept it around forever. Every time we tried to post a reply, it was
added to this document, even if it wasn't saved due to some error.
This resulted in duplicate replies when the user managed to actually
save.
Now we only keep around the HTML string and some metadata fetched from
the API, and rebuild the actual document every time before adding a
reply.

This ensures that expired tokens are refreshed and retried, while
invalid tokens caused by the user logging in/out cause an error. We
should think about displaying a better interface for the latter case.

Native Range objects are automatically updated when the DOM elements
they refer to are affected (e.g. detached from the DOM, or their offset
changes because of siblings being added/removed).
This seemed harmless or maybe even slightly useful, but it turns out
it conflicts with VisualEditor, which has to wrap the entire page in a
new DOM node when it opens (and unwrap it when it closes), effectively
temporarily detaching it from the DOM, which destroys all our ranges.
Just use a plain object that stores the same data as a Range. And when
we need to use Range's API, we can simply construct a temporary one.

This sets up the tags:
* discussiontools
* discussiontools-reply
* discussiontools-edit (not yet implemented)
* discussiontools-newsection (not yet implemented)
The tags are flagged as user-addable, because otherwise they can't be
passed through to the VE API (at least, not without editing it so that
it explicitly knows about them, which seems like a strange
interdependency). It's assumed that letting users who know about the
tags add them to random changes via action=editchangetags would be
(a) the pettiest and most inconsequential vandalism possible, and
(b) unlikely to happen.
This relies upon I2c1d0f8d69bc03e5c1877c790247e165f160e966 in
VisualEditor to not also tag the edits with `visualeditor`.

I don't like that I had to special-case `<p>` tags (top-level
comments) in this code. I feel like it should be possible to handle
top-level comments and replies in a generic way, but I couldn't find
a way to do it that actually worked.
Notes about changes to the behavior, based on the test cases:
* Given a top-level comment A, if there was a "list gap" in the
replies to it: previously new replies would be incorrectly added at
the location of the gap; now they are added after the last reply.
(T242822)
Example: "pl", comment at "08:23, 29 wrz 2018 (CEST)"
* Given a top-level comment A and a reply to it B that skips an
indentation level: previously new replies to A would be added with
the same indentation level as B; now they are added with the
indentation level of A plus one. (The old behavior wasn't a bug, and
this is an accidental effect of other changes, but it seems okay.)
Example: "pl", comment at "03:22, 30 wrz 2018 (CEST)"
and reply at "09:43, 30 wrz 2018 (CEST)"
* Given a top-level comment A, a reply to it B, and a following
top-level comment C that starts at the same indentation level as B:
previously new replies to A would be incorrectly added in the middle
of the comment C, due to the DOM list structure; now they are added
before C. (T241391)
(It seems that comment C was supposed to be a multi-line reply that
was wrongly indented. Unfortunately we have no way to distinguish
this case from a top-level multi-line comment that just happens to
start with a bullet list.)
Example: "pl", comments at "03:36, 24 paź 2018 (CEST)",
"08:35, 24 paź 2018 (CEST)", "17:14, 24 paź 2018 (CEST)"
* In the "en" example, there are some other changes where funnily
nested tags result in slightly different results with the new code.
They don't look important.
* In rare cases, we must split an existing list to add a reply in the
right place. (Basically add `</ul>` before the reply and `<ul>`
after, but it's a bit awkward in DOM terms.)
Example: split-list.html, comment "aaa"; also split-list2.html
(which is the result of saving the previous reply), comment "aaa"
* The modifier can no longer generate DOM that is invalid HTML, fixing
a FIXME in modifier.test.js (or at least, it doesn't happen in these
test cases any more).

* Add config option $wgDiscussionToolsUseVisualEditor (default false).
* Add new modules ext.discussionTools.ReplyWidgetPlain and ...ReplyWidgetVisual,
replacing ...ReplyWidget. Load only one of them depending on the config.
TODO:
* Also add the visual mode of VisualEditor, this only uses NWE now.
There is already code to support saving from it, but no mode

The packageFiles system makes it easier to export site config data
from PHP to JS, which we need a lot of, but it's awkward when mixing
it with defining and accessing classes via a namespace like mw.dt.
The only thing remaining in mw.dt is mw.dt.pageThreads, which is
described to be "for debugging", so we should keep it easy to type.
Also we still use the namespace for documenting classes.
Everything else can be reached by require()'ing a ResourceLoader
module, for example instead of `mw.dt.ui.ReplyWidget`
you'd do `require( 'ext.discussionTools.ReplyWidget' )`.
(When debugging from browser console, use `mw.loader.require` instead.)

Possible use cases:
* Matching comments between PHP and Parsoid HTML [implemented here]
* Finding the same comment in a different revision of a page
(e.g. while resolving an edit conflict, or to allow resuming
composition of autosaved comments) [implemented for highlighting
user's own posted comment only]
* Permanent links to comments [future]
The reasoning for this form of ID is:
* _Timestamp_ by itself is a nearly unique identifier, so it's a good
thing to start with
* Users may post multiple comments in one edit (or in many edits in
one minute), so we need the _sequential number_ to distinguish them
* _Username_ is probably not required, but it may reduce the need
for sequential numbers, and will help with human-readability if we
add permanent links
The ID remains stable when a new comment is added anywhere by anyone
(excepts comments within the same minute by the same user), or when a
section is renamed.
It's not always stable when a comment is moved or when an entire
section is moved or deleted (archived), but you can't have everything.

Otherwise the rest of the page may shift if hiding the link changes
line-wrapping. It felt super confusing when it happened to me while
I was testing an unrelated thing.
