Catrope e95cc34978 (bug 42469) Leading newlines in <pre>s get eaten
HTML DOM has annoying behavior for <pre>s where .innerHTML eats the
first newline in a <pre>. Work around this by explicitly adding a
newline in the data->DOM converter if the <pre> already contained a
newline.

There is a separate bug in Parsoid that causes the newline to be lost
anyway, filed as bug 42666

Catrope e123a39b4e Handle annotated inline nodes in the converter
Was broken both on the way in and on the way out.

* Move alien restoration (data->DOM) out of the main getDomFromData()
  function and into getDomElementFromDataElement(). This means the
  comment about District 9 is gone (sniff), but moving this here ensures
  all code paths hit it (previously, it was assumed annotated nodes
  could never be aliens).
* In the DOM->data converter, add annotation application to
  getDataElementFromDomElement() (for content nodes) and createAlien()
  (for aliens). Previously, these nodes would not get annotations.
** ve.AnnotationSet doesn't have a constructor that takes an array, we
   should fix that.

This is cleaner than passing around the attributes separately, and it
allows us to access the annotations in dm.LeafNode as well.

Catrope bf7b243627 (bug 42121) Change markers lost for first paragraph on new page
When editing a new page, or loading an empty page into the editor, the
converter generates a paragraph so the document isn't completely empty.
This paragraph is then unwrapped on the way out, potentially destroying
change markers and generally producing strange HTML output.

Mark this paragraph with generated=empty rather than generated=wrapper,
and only unwrap it on the way out if it's still empty. This means we
cleanly round-trip empty documents (and empty list items and the like),
but if the user enters text, we create a paragraph like we're supposed
to.

Catrope 662880605c (bug 42119) Handle alienation in wrapping mode properly
When alienating in wrapping mode, we need to look at the type of tag to
decide whether to create a wrapped alienInline, or to interrupt the
paragraph for an alienBlock.

This was being done just fine for the general alienation case
(unrecognized tag), but not for the special cases (mw:unrecognized,
about groups).

* Centralize the logic for ending a wrapper in stopWrapping()
* Move the wrapping-contingent block/inline detection logic into
  createAlien()
* Simplify the terrible if statement to decide whether a future decision
  requires us to stop wrapping. Instead, detect the cases in each code
  path separately and call stopWrapping() as appropriate
* Add tests

Catrope 1234a702c9 (bug 42218) Add MWEntityNode
<span typeof="mw:Entity"> tags are now correctly represented in the
model, and rendered in CE. There are still issues with cursor movement
etc. in CE.

Because the prioritization mechanism for annotations vs nodes is broken
in the current "node API", I had to hack two special cases for mw:Entity
into the converter. I also had to change the converter to ignore the
children of inline nodes (this was a legitimate bug, but had never come
up before).

Trevor Parscal 2c8411eb62 (bug 41947) Propagate change markers when unwrapping generated nodes
Editing the text of a list item results in a change marker on the
paragraph within that list item. However, that paragraph usually isn't
present in the HTML, so the converter unwraps it when converting back to
HTML, and the change markers are lost. Instead, transfer the change
markers to the <li>.

Catrope d4ea93b872 Add basic support for about groups
About groups are HTML structures like the following:
<div about="#mwt1">....</div>
<span about="#mwt1">...</span>
<div about="#mwt1">...</div>
When about groups are alienated, they are now merged into one alien
node, rather than producing a separate alien node for each sibling.

This is very basic about group handling, because it only works for
groups of directly adjacent siblings (text nodes are permitted in
between, but nothing else) assumes all about groups are aliens (which
is currently true).

* Before processing an element in the DOM->data converter, perform about
  grouping on its children. This temporarily wraps about groups in
  <div data-ve-aboutgroup="value of about attribute">
* Extended createAlien() to handle single nodes as well as wrappers
  holding multiple nodes.
* In the data->DOM converter, temporarily wrap multi-node aliens in
  <div data-ve-multi-child-alien-wrapper="true"> . This makes the rest
  of the algorithm easier.

Catrope 857535b63f Introduce meta-linmod
* ve.dm.Converter still generates metaInline/metaBlock elements as
  before, it's not affected by this change
* ve.dm.Document constructor splits its input into "real" data and
  metadata
** Metadata is stored in this.metadata (the meta-linmod) as a sparse
   array of arrays, with an element for each offset in this.data
** this.data itself does not contain the metadata
** This means the node tree also doesn't contain the metadata
** Which means CE doesn't know about it at all
* All splice operations on the linear model are sent through
  ve.dm.Document.spliceData(), which performs the splice and syncs the
  meta-linmod
** Metadata in the removed range is reaped and added to the metadata for
   the offset immediately following the removal
* ve.dm.Document.getFullData() splices the linmod and meta-linmod back
  into each other; this "full data" is then fed back to ve.dm.Converter

Catrope 84e598953a Wrap inline elements properly
The HTML "1<br/>2" was being converted to a linmod that looked like
"<p>1</p><br></br><p>2</p>". This commit fixes the wrapping logic such
that the result is "<p>1<br></br>2</p>" instead. In general, inline
nodes (content nodes) should not interrupt the wrapping, but block nodes
should.

This creates a problem for alien nodes: normally, we determine whether an
alien node is a block alien or an inline alien based on context, but if
we're in wrapping mode we're unsure of the context. We can't tell the
difference between "1<tt>Foo</tt>2" (should be wrapped as one, because
tt is inline) and "1<figure></figure>2" (1 and 2 should be wrapped
separately, because figure is block) using context alone, so in these
cases (and ONLY in these cases) we look up whether the HTML tag in
question is an inline tag or a block tag and use that to decide.

Catrope 7b96fbe3d2 Add a node type for meta nodes
This node type represents <meta> or <link> (transparently, based on the
style attribute). I had to make two node types for this and hack the
toData conversion code directly into ve.dm.Converter, because we don't
have native support for node types that can be both inline and block.
(We should add this in the node API rewrite.)

The CE implementation renders a placeholder (with the same styles as an
alien node) right now. I'm not sure how nice that is, but it's better
than rendering raw <meta>/<link> tags.

This whole thing is a total pile of hacks to make VE deal with
<meta>/<link> tags until we have a proper node types API.

Catrope c6cb537f1a Fix bugs in whitespace preservation for aliens
This was broken in three different ways:
* On the way in, we were applying whitespace to an array of elements
  rather than the actual element, so the whitespace wasn't stored.
* Whitespace processing on the way out was skipped for aliens because
  they had their own code path. Refactored this so alien openings and
  regular openings share much more code, including whitespace output.
* Somewhat unrelatedly, innerPost output was broken for paragraphs
  containing inline elements, because the inline elements' processing
  polluted lastOuterPost. Discovered this because my test with inline
  aliens also happened to be the first test of whitespace preservation
  in paragraphs with inline content elements. Fixed by explicitly
  skipping content nodes when outputting whitespace.

Fixed these issues and added a test case.

Catrope 5e7c14c868 Manage annotations in ve.AnnotationSet object
Introduced the ve.AnnotationSet class to manage sets of annotations. This
is a generalization of ve.OrderedHashSet, a class that manages a set
using an array and an object keyed by hash.

Converted everything that stores, tracks or passes around annotations to
use ve.AnnotationSet. In particular, this means the linear model now
contains AnnotationSets instead of hash-keyed objects.

This allows us to maintain the order of annotations in the linear model,
and will help fix bugs with annotation ordering and splitting.

Catrope 452c759914 Preserve whitespace between elements
This commit fully utilizes all four positions in the internal.whitespace
array. Outer whitespace is now preserved as well, and is duplicated
either in the adjacent sibling (one node's outerPost is the next
sibling's outerPre) or in the parent (a branch node's innerPre is its
first child's outerPre, and its innerPost is its last child's
outerPost). Before restoring saved whitespace, we check that these two
agree with each other, and if they disagree we assume the user has been
moving stuff around and don't restore any whitespace in that spot. The
whitespace at the very beginning and the very end of the document (i.e.
the first node's outerPre and the last node's outerPost) isn't
duplicated anywhere, nor is inner whitespace in content nodes.

The basic outline of the implementation is:
* When we encounter whitespace, strip it and store it in the previous
  node's outerPost. Also store it in nextWhitespace so we can put it in
  the next node's outerPre once we encounter that node.
* When we encounter whitespace in wrapped bare text, we don't know in
  advance if it's gonna be succeeded by more non-whitespace (in which
  case it needs to be output verbatim), or not (in which case it's
  leading whitespace and needs to be stripped and stored). The fact that
  annotations are nodes in HTML makes this trickier. So we write the
  whitespace to the temporary linmod and store it in wrappedWhitespace,
  then if it turns out to be trailing whitespace we take it back out of
  the data array and record it the usual way.
* Because text nodes can contain any combination of leading whitespace
  actual text and trailing whitespace, and because we may or may not
  already have opened a wrapping paragraph, there are a lot of different
  combinations to handle. We handle all of them but the resulting code
  is pretty dense and verbose.

More low-level list of changes:

In getDataFromDom():
* Added helper function addWhitespace() for storing whitespace for an
  element
* Added helper function processNextWhitespace() for processing any
  whitespace passed on from the previous node via the nextWhitespace var
* Rename paragraph to wrappingParagraph. Make wrapping default to
  alreadyWrapped so we can simplify wrapping||alreadyWrapped and
  !wrapping&&!alreadyWrapped. Add wrappingIsOurs to track whether the
  wrapping originated in this recursion level (needed for deciding when
  to close the wrapper).
* Add prevElement to track the previous element so we can propagate
  whitespace to it, and nextWhitespace so we can propagate whitespace to
  the next element.
* Remove previous newline stripping hacks
* Integrate the logic for wrapping bare content with the outer
  whitespace preservation code
* Remove wrapperElement, no longer needed because we have a dedicated
  variable for the wrapping paragraph now and what was previously inner
  whitespace preservation for wrapper paragraphs is now covered by the
  outer whitespace preservation code.

In getDomFromData():
* Reinsert whitespace where appropriate
** outerPre is inserted when opening the element
** This covers outerPost as well except for the last child's outerPost,
   which is handled as the parent's innerPost when closing the parent.
** innerPre and innerPost are inserted when closing the element. Care is
   taken not to insert these if they're duplicates of something else.
* Propagate each node's outerPost to the next node (either the next
  sibling or the parent) using parentDomElement.lastOuterPost. We can't
  get this using .lastChild because we will have destroyed that child's
  .veInternal by then, and we can't tell whether a node will be its
  parent's last child when we process it (all other processing,
  including first child handling is done when processing the node itself,
  but this cannot be).
* Special handling is needed for the last node's outerPost, which ends
  up in the container's .lastOuterPost property.

Tests:
* Allow .html to be null in data<->DOM converter tests. This indicates
  that the test is a one-way data->DOM test, not a DOM->data->DOM
  round-trip test. The data will be converted to HTML and checked
  against .normalizedHtml
* Update existing tests as needed
* Add tests for outer whitespace preservation and storage
* Add test for squashing of whitespace in case of disagreement (this
  requires .html=null)

Catrope 7319038ed6 Strip generated <p> tags in dataToDom
domToData wraps bare content in paragraph elements, which were then
converted to <p> tags by domToData. With this fix, HTML with "missing"
<p> tags actually round-trips through the editor correctly now, rather
than having <p> tags added wherever VE believes they should exist.

* Mark generated paragraph elements with .internal.generated = 'wrapper'
** This signifies the wrapper was generated but its contents were not,
   so the right thing to do when converting back to HTML is to remove
   the wrapper and keep the contents. We might want to use other values
   of generated in the future.
* Unwrap nodes with generated=wrapper when converting to HTML

Tests:
* Add 'generated': 'wrapper' as appropriate. Only affects 1 test
* Remove 'normalizedHtml' for this test because it is no longer needed
** Need to keep 'normalizedHtml' for now because we normalize hrefs
* Eventually the main example should test bare content, but that
  requires touching a lot of stuff. The main example could use some
  beefing up anyway.

Catrope 6f8307d5d2 Update LinkAnnotation for Parsoid href changes
Because the Parsoid prefix format changed from /mw:Foo to /mw/Foo , the
href format for internal links has changed from "/Foo" to "Foo". So the
href is now simply the title, except that it may be preceded by one or
more "../" if the title of the page we're on contains a '/'.

So instead of stripping the leading slash from internal link hrefs and
putting it back on the way out, only strip any leading "../"s and dump
the titles directly into the hrefs on the way out.

Also update the link test case for this, and add a test case for the ../
stripping.

Catrope 7f5dc887ea Do underscore/space conversion in internal link targets
Convert underscores in the href attribute to spaces in the linear model,
and back to underscores when going back to HTML. This ensures the link
targets displayed to and edited by the user look nice

Catrope 2b548a002f Get link title from href by stripping article path
This means we don't have to rely on data-rt.sHref. It also means that
we'll now be showing the canonical link target in the link inspector
rather than the link target as entered by the user, but that's fine.

Also change test to have href differ from sHref to show that we use
href.

Catrope 67e11ebbc3 Make VE work again with the link RDFa changes in Parsoid
This is ugly but makes things work again. I intend to clean this up once
we have a better attribute API

* Recognize mw:WikiLink, mw:SimpleWikiLink, mw:ExtLink,
 mw:NumberedExtLink and mw:UrlLink
* Support is incomplete because we can't get to the annotation text with
  the current API
* Preserve all unhandled attributes rather than special-casing data-mw
* Update remaining code using data-mw (sHref and stx extraction) to
  account for the data-mw -> data-rt rename
* Update tests accordingly
