The EventEmitter API we inherited from Node.js and then bastardized was
getting awkward and cumbersome. The number of uses of ve.bind was getting
out of control, and removing events meant caching the bound method in a
property. Many of the "features" of EventEmitter wasn't even being used,
some causing overhead, others just causing bloat. This change cleans up
how EventEmitter is used throughout the codebase.
The new event emitter API includes:
* emit - identical to the previous API, no longer throws an error if you
emit error without a handler
* once - identical to the previous API, still introduces a wrapper* on -
compatible with the previous API but has some new features
* off - identical to removeListener in the previous API
* connect - very similar to addListenerMethods but doesn't wrap callbacks
in closures anymore
* disconnect - new, basically the opposite of addListenerMethods
Another change that is made in this commit is mixing in rather than
inheriting from EventEmitter.
Finally, there are changes throughout the codebase anywhere
connect/disconnect could be used.

* Allow manual truncation of the undo stack to prevent redoing something
that's been undone
Change-Id: I17534d6724fc2b325152cb2f665c6816f44232c1
Remove all manual changes to SF ranges as these are not
undoable. Instead change translate range to default to
outer expand and build functionality around that behaviour
never changing.
As translate range is always outer I don't think we need to
check for start and end crossing over?
Added more undo tests to assert these selections are maintained
properly, and added the test case to 'update' for when and undo
point is overwritten.
Insert content now results in a selection over the inserted
content. Most usages were expecting this anyway and were
followed up with an adjustRange(-length,0) which is no longer
necessary.
Noticed that the link inspector case was never being triggered
as word boundary was always expanding to at least one char (mainly
for Hanzi selection). This doesn't make much sense as single
spaces get auto selected so removed this functionality.
Split collapseRange out into collapseRangeToStart and
collapseRangeToEnd as this may be required to get the old
behaviour (range moves to end after insert).

As jQuery hash problems in some cases converting HTML, it is
easier just to store the original DOM elements.
The bulk of this commit is fixing the tests as although we have an
assertion for comparing DOM elements, we don't have one for comparing
objects or arrays which may contain DOM elements.
ve.js
* copyObject & copyArray fixed to run cloneNode(true) on any item
of type Node.
* Added callback function so an object/array can be copied with
modifications.
ve.qunit.js
* Added deepEqualWithDomElements: Using the new copyObect/Array
callback, we can copy the incoming object and convert any nodes
to node summaries, then just run the normal deep equal comparison.
ve.dm.AlienNodes.js
* Instead of storing HMTL we store cloned DOM elements which we can
send straight back to the converter without any processing.
ve.dm.example.js
* Updated tests to expect DOM elements instead of HTML.
ve.dm.Converter.test.js
* Updated tests to use deepEqualWithDomElements

In this case, selectNodes() returns the paragraph, which is not a content
node, and so newFromContentBranchConversion() decides to do nothing at all.
This change makes newFromContentBranchConversion() more intelligent about
finding the content branch to operate on, fixing cases such as these
where selectNodes() returns the content branch itself rather than one of
its children.

fixUpInsertion now returns an object with both data and offset
which allows offset changes.
Within fixUpInsertion we lazy-generate first/lastChildStack which
is a list of parent nodes for which the current node is the first/last
child. Whenever we try to close off a node we check these stacks and
if they are populated we instead use a recursive call to start
fixUpInsertion again but with the offset shifted by 1.

Clearing by type in SurfaceFragment didn't actually work. Instead,
it followed a code path intended for setting and created an annotation
of that type with no data, then tried to clear that. What we really
want to do there is clear anything with that type.
This fixes the bug where unbolding of text that was already bold in
the article didn't work.

This is minimise the amount of data we need to serialise when
sending this over the wire.
The minimal IVStore data is added to the MW bug report, and
editedData fixed to only return the data array, not the full
LinearData object.
Documentation in AnnotationSet has finally been updated to
refelect the fact that it only stores Annotations
(was previous the generic OrderedHashSet).
getAnnotationFromOffset has been split out into a function
that just returns this indexes so that in cases where we
don't need the values we don't do an unneccesary store lookup.

The fixUpStack is actually redundant code and closingStack
and openingStack handle all our cases. It was causing the
insertion to try to correct balance itself in the middle
of inserting two paragraphs, causing the creation on an
empty paragraph between them.
Added a test case for the fix and other cases to make
sure removing fixUpStack hasn't caused problems.

Parsoid is sending us some unescaped HTML in the data-parsoid
attribute. When we try to rebuild ref nodes (inline aliens)
this confuses Firefox which tries to sanitise the HTML by converting
<ref/> to <ref></span>.
As a temporary fix we can manually escape <>'s inside the
data-parsoid attribute.
Also in this commit the new MWReference nodes have been moved
to experimental as they are incomplete.

To help the selective serialiser we can return the original
HTML for generated content if it is unmodified.
As the output of toDomElements now depends on changes
to the dataElement we now have a 'modify' function in
the some test cases.
We also now have 'storeItems' to assert that the index-value
store is correctly populated and for loading values back
into the store for toDomElements tests.
Also make 'mw' an attribute and remove 'about' property.

Also add detection for whether the browser is actually broken (most are,

addSet:
* Instead of indexing items in the store, just union the indexStore arrays
removeSet/removeNotInSet:
* difference or intersect the indexStore arrays
filter:
* push indices into the result set instead of values
simpleArrayUnion/Intersect/Difference have been created as utilities
in ve. They are prefixed 'simple' because they use object keys to
do fast in-array comparisons. This means they are limited to string
values or values which will compare as strings (e.g. numbers).

By removing the transaction listeners from surface fragments we
no longer have to make sure they are always manually destroyed.
In order to retain the functionality of having fragments update
with transactions elsewhere we keep a pointer to a place in the
new complete history stack in the surface. The complete history
stack records all transactions, even undone ones.
Whenever getRange is called we replay all transactions in the
complete history (in the correct order) since the fragment was
last updated.
Also in this commit:
* Updated Format/IndentationAction to test undo(). This increases
coverage of surface fragment behaviour.
* .range is always accessed by .getRange now, although as an
optimisation we can use the noCopy mode when we a sure the
returned range will not be modified.
* Added undo test to .update (previously .onTransact)

This was broken, especially in wrappers.
Changed the wrapping algorithm so that meta items are placed outside
wrappers if possible. On the left-hand side, this is already the case:
we don't open wrappers for meta items. On the right-hand side, this is
accomplished by buffering the meta items and only inserting them when
we encounter either real text (not whitespace) or the end of the wrapper.
If we're interrupted by real text, we insert the meta items with the
unmodified whitespace. If we're interrupted by the end of the wrapper,
we insert the meta items outside of the wrapper with whitespace stripped.
Internally, this is done by stripping the whitespace into the whitespace[0]
of the meta item to its right. Then when we output the meta items, we
either decide to 'restore' the whitespace, or to 'fixup' by also setting
whitespace[3] on the element before the whitespace.

Objective:
Make it possible for inspectors to inspect nodes or annotations, rather
than only annotations. Meanwhile, also make it possible for dialogs to
edit an annotation.
Strategy:
Switch from using type patterns to associate inspectors with annotations
to using arrays of classes, similar to how dialogs already work.
Introduce a view registry which provides lookups for relationships
between models and views. This is more centralized and less repetitive
than implement matching functions for both annotations and nodes in both
the dialog and inspector factories.
Changes:
*.php
* Added links to new file
ve.AnnotationAction.js
* Removed unused parameter to filter annotations using a string or regexp
ve.dm.AnnotationSet.js
* Switched from property/value arguments to callbacks
ve.ui.*(Dialog|Inspector).js
* Replaced type patterns with class lists
* Added class to view registry
ve.ui.*Tool.js, ve.ui.Context.js
* Updated model/view relationship lookup
ve.ui.*Factory.js
* Removed overly-specific lookup functions
ve.ui.Inspector.js
* Removed typePattern property
* Updated model/view relationship lookup
ve.ui.ViewRegistry.js
* New class!
* Migrated node and annotation lookup functions from factories

So. It turns out that the design of SurfaceFragment is a little -
shall we say - wonky.
One of the best things about ve.dm.SurfaceFragment is its magical
ability to retain the intention of its range, even as transactions
are being processed. This ability is granted by each fragment
listening to the surface's change event, and responding by using
translateRange for each transaction that gets processed. Surface
fragments also have these clever methods that allow you to get a
fragment based on another, which makes adjusting the range easy to do
inline without having to manually store multiple fragments or
modifying the original.
This sounded good, and we seemed to all be convinced it was well
designed. But if you add a console.log( 'hello' ); to the first line
of ve.dm.SurfaceFragment.prototype.onTransact, and then start using
the bold tool on various selections of text, you will find that there
may indeed be a flaw. What you will probably realize is that the
number of times that particular line of code is being called is
disturbingly large, and increases each time you do just about anything
in the editor. What's going on? How did we get here? Read on…
It turns out that fragments are immortal. We create them, they listen
to the surface's transact event, we are done with them, but the
surface keeps on emitting events to the now long forgotten about
fragments. They continue to build up over time, never go out of scope,
and bloat the hell out of our program.
The same ended up being true of toolbars - and each time the context
menu fired up a new one the old one was left in limbo, still
responding to events, still taking up memory, but not being visible to
the user.
All of this immortality was causing strange and difficult to track
down problems. This patch fixes this by introducing a destroy method.
This method unbinds events, allowing the object to finally fall out of
scope and die - and more importantly stop receiving notifications of
changes.
This is a hack, but Ed will no doubt get this situation sorted out
properly by making fragments lazy-evaluate their selections by only
storing an identifier of the most recent transaction they were based
on, see bug 47343.

Before, it took an array of objects and translated those to indexes
using the store. Literally every caller outside of the test suite got
an array of indexes from the linear model, translated those to objects,
then passed them into the AnnotationSet constructor which translated
them right back to indexes.
The previous behavior was kind of ridiculous on its face, but the
reason we found it is because Inez was investigating the performance
degradation when bolding a line and found that half of it was due
to the hundreds of ve.getHash() calls caused by this behavior.

Context-sensitive nodes are HTML elements like <caption> that can only
appear in certain contexts (<table> in this case). This means that
serializing them by throwing them in a <div> and calling .innerHTML
fails, because the browser knows a <caption> can't be in a <div> and
unwraps it. jQuery's .html() function is clever though and knows to wrap
<caption> in a <table> (and has similar rules for other elements).
So use jQuery's .html() rather than manual .innerHTML stuff.
