Arlo Breault b8d4bb1f37 Set inEmbeddedContent when running processRefsInReferences
In 47506af, serializing references content to be added to data-mw was
delayed until we were inserting the reference into the dom, to give us a
chance to mark up errors about not finding named ref content.  After
which, the content is cleaned out of references to make room for list
items that belong there.

In 6bd0594, we noted that we can't store linkback from embeded content
since the content is released after serializing and won't be available
when it comes time to mark it up with errors.

Similarly, the linkbacks added to other groups from the references
content won't be available after inserting that reference and so we
shouldn't be holding on to them either.  This means that we won't be
marking them up for the named error above but with the benefit that we
won't crash when trying to access these linkbacks from another group.

A test case is added which crashes trying to access a linkback from a
group that has already been inserted.

Note that the extension to the legacy parser considers referencing
another group from group content to be
"cite_error_references_group_mismatch".  If we choose to also do that,
we may be able to reverse this change.

sbailey a8e299b21e Added cite error checks for numeric digit in name
* Note: the <ref name="1"> numeric is flagged as an error, but
   <ref follow="1"> is not flagged as well as it would be duplicitous.
   We are proposing that Numeric digits as a name be changed to
   a warning as Parsoid Cite handles them properly without error.

   Background: The core Cite extension started off not allowing numeric
   names because the data structure they used made it inconvenient,
   but Parsoid Cite has a separate index for named refs.
   The core Cite devs thought there was potential for a conflict in
   the ids if numeric names were allowed. The ids that core uses
   follow the pattern:
     for no name defined:  cite_ref-1             cite_ref-2
     for name="refname":   cite_ref-refname_3-0   cite_ref-refname_3-1
   so for name="1" at worst you might see ids like:
     cite_ref-1  or  cite_ref-1_2-0
   so that does not produce conflicting IDs and isn't a concern,
   and that is the pattern that Parsoid Cite uses.

 * Error case of numeric in name and follow and two tests that
   validate errors.

Arlo Breault 1ac603ff1c Always wrap follows content
Avoids crashers from trying to serialize the named content twice if
there's a valid follow with some other error, as expected in the FIXME.

This introduces a backwards incompatibility for invalid follows, which
will result in the contents of the ref being dropped.

A test is added to assert that selser will save us for the most part.

Subramanya Sastry f00325d6cc Introduce preprocessing in the HTML -> WT direction
* This patch introduces a preprocessing step on the edited DOM.

* Existing preprocessing code has been extracted into the
  preprocessDOM method.

  Any registered extensions preprocessors are invoked on the DOM.
  So, this assumes that the htmlPreprocess extension listener is only
  applicable to the edited DOM. If we want to expose the concept of
  selective serialization through the API, we may want to add an
  additional interface method / listener to the DOMProcessor class.

  As of this patch, this is somewhat theoretical since there are no
  such extension handlers registered on either DOM. Future patches
  can clarify this better as specific needs arise.

* The handler also calls the serializer's custom preprocessing steps.
  This step is applicable to both the original as well as edited DOM
  (since DOM Diff is impacted by the results). If a need arises,
  in the future, we may introduce a new extension DOM processor method
  that applies to both original and edited DOMs.

* Right now, only selser strips section tags and non-selser wts
  doesn't need to. So, preprocessDOM there is empty. Additional
  selser-only DOM preprocessing will show up in later patches.

* Moved a stub HTML->WT preprocessor in Cite extension to RefProcessor.

Arlo Breault 2f09cdb732 One document to rule them all
The description in T179082 suggests that by using one document for the
entire parse, we'd probably see some performance gains from not having
to import nodes when we get to the top level pipeline and we'd avoid the
validation errors from 19a9c3c.

However, the spec seems to suggest creating a new document when parsing
an HTML fragment,
https://html.spec.whatwg.org/#html-fragment-parsing-algorithm

And, indeed, domino implements it that way,
12a5f67136/lib/htmlelts.js (L84-L96)

So, the request in T217705 may be a little misguided.

What then is this patch good for?  In T221790 the ask is that
sub-pipelines produce DocumentFragment which make for cleaner interfaces
and less confusion when migrating children.

The general outline here is that a document is created when the
environment is constructed that gives us the 1-1 correspondence.
Sub-pipelines do create their own documents for the purpose of tree
building, as in the fragment parsing algorithm, but are then immediately
imported to DocumentFragments to be used for the rest of the
post-processing passes.

Thiemo Kreuz 7ce27b432f Stop using Language::formatNum to localize separators
This is done to make the discussion in If3dcfd7 easier.

When we introduced this code we actually used it to format
entire numbers. We had to change this later to *not* localize
digits, but only separators. Language::formatNum is and always
was able to do this, so we just continued to use it.

This is discussed now.

It turns out there is only a single place left where we use
formatNum, and it does nothing but localizing the decimal
point. There is another way to do the same.

C. Scott Ananian 98d68bfa6e Use wikimedia\object-factory for extension objects; hook up ExtensionRegistry
Mediawiki prefers to use an object factory pattern when creating objects.
Use ObjectFactory consistently when creating objects specified using the
extension API.  Thanks to the 'allowClassName' option to
ObjectFactory::getObjectFromSpec(), this is mostly consistent with
previous practice.  Note that the string class name is short for:
   [ 'class' => Foo::class ]
and so we've chosen to rename the 'class' property in the extension tag
configuration so that we have (in long form):
   [ 'name' => 'Cite', 'handler' => [ 'class' => Cite::class ] ]
instead of nesting two keys named 'class' in a row.  (And besides, the
content isn't really a 'class' any more, it's an "object factory
 specification".)

SiteConfig::registerExtensionModule() can now take *either* an object
factory specification for an ExtensionModule object (including a bare
class-string) *or* the contents of the configuration array that
would be returned by ExtensionModule::getConfig(), in which case it
creates an anonymous ExtensionModule object for you.  It's expected
that the latter will be preferred in extension.json, but we use the
former for our internal extension implementations at the moment.

Finally, call SiteConfig::registerExtensionModule() on the results
of ExtensionRegistery::getInstance()->getAttribute('ParsoidModules')
when running in integrated mode.  This allows you to register your
extension with a clause such as the following in your extension.json:

(simple case, naming a class which implements ExtensionModule)
{
  "name": "JsonExtension",
  "manifest_version": 2,
  ...
  "ParsoidModules": [ "Wikimedia\\Parsoid\\Ext\\JSON" ]
}

(complex case, putting the configuration array into extension.json)
{
  "name": "Cite",
  "manifest_version": 2,
  ...
  "ParsoidModules": [
    {
      "name": "Cite",
      "domProcessors": [
	"Wikimedia\\Parsoid\\Ext\\Cite\\RefProcessor",
      ],
      "tags": [
	{
	  "name": "ref",
	  "handler": "Wikimedia\\Parsoid\\Ext\\Cite\\Ref",
	  "options": {
	    "wt2html": { "sealFragment": true }
	  },
	},
	{
	  "name": "references",
	  "handler": "Wikimedia\\Parsoid\\Ext\\Cite\\References",
	  "options": {
	    "html2wt": { "format": "block" }
	  },
	}
      ],
      "styles": [
	"ext.cite.style",
	"ext.cite.styles"
      ]
    }
  ]
}

The syntax above, with `ParsoidModules` as a top-level attribute, requires
I6c74938883376ec17f3790678b435585083a440f in core.  However, with or without
that patch, the following also works:
{
  ...
  "attributes": {
    "Parsoid": {
      "Modules": [ ... ]
    }
  }
}

duplication.  Create Wikimedia\Parsoid\Ext\DOMUtils so that extensions
can use these methods as well.

(a.k.a. $this->refSequence) is not incremented. This was the case
before, just not covered by any test.

CI already ensures that VisualEditor is loaded alongside Cite, so
the defensive check in the code isn't needed; ext.cite.visualEditor is
defined statically, it's just injected into the page dynamically in the

Thiemo Kreuz 6389459b1e Refactor newline logic for auto-generated <references> sections
This change does have two effects:

1. Instead of prepending a newline individually in every possible
code path, we do it one time at the end. But only if there is
something in the output. This does not change anything, as proven by
the unchanged parser tests.

2. I removed the newline between the <h2> and the generated
<references> element. Note that both these elements are created in
the same method, next to each other. So there is no way this can
influence other wikitext. Unfortunately this code path is executed
only when using the *preview* function, and impossible to be covered
by parser tests because of this. However, it's covered by unit tests.

This refactoring is motivated by, but not required for T148701.

Bartosz Dziewoński 3678215a77 Add a newline in wikitext before autogenerated reflist
Previously the reflist was added at the end of the last line of text,
which messes up paragraph wrapping (as seen in many test cases), and
generated invalid HTML when the last line was a list item (T148701).

(second try, previously reverted in 8c933d03c5)

Note this affects only pages where the <references /> tag is missing,
and the references section is auto-generated at the very end of the page.

C. Scott Ananian b4aefae357 Add extension registration mechanism to SiteConfig
This will be called by the ExtensionRegistry in core for extensions
that are Parsoid-compatible.  The set of registered extensions is part
of the SiteConfig, which bundles all the configuration for a particular
Parsoid instance.

In addition, renamed some classes to make things clearer:
`ExtensionModule` is the thing which is registered; it bundles a
number of `ExtensionTagHandler`s, `ContentModelHandler`s, and DOM
processors (which don't have a proper interface yet).  There are a set
of core handlers, which include wikitext, JSON, and a few extension
tags (<pre>, <nowiki>, <gallery>).

Subramanya Sastry 5626d6ca62 ParsoidExtensionAPI: Add domToWikitext method + fix Cite to use it
* We only had a htmlToWikitext API method whereas we have been
  trying to stay in DOM land all along. With this change, extensions
  can use the intuitive domToWikitext method when they are dealing
  with DOM nodes.

* Renamed WTS's serializeHTML method to htmlToWikitext and added
  a domToWikitext method there as well which ParsoidExtensionAPI uses.

* Turns out that <ref>s were converting DOM to HTML and then using
  the htmlToWikitext method. I switched it use the domToWikitext
  method. However, turns out WTS requires a <body> element for its
  top-level method!

  For now, while we figure out if that can be changed to be more
  lenient, added an internal DOM -> HTML conversion in the
  domToWikitext method. When we fix WTS, this DOM -> HTML -> DOM
  roundtrip can be eliminated.

Subramanya Sastry 04e9292576 Provide utility classes for extensions
* Added DOMDataUtils, WTUtils, and Util for use by extension
  developers. These classes might acquire more functionality in the
  future based on usage and need.

* Added PHPUtils for a single helper to work around a GC bug in PHP.
  Once we move on to a newer version of PHP where this is fixed, we
  can get rid of this class and helper.

* These classes proxy the various helpers used by currently ported
  extensions. For reasons of coherency, the set of helpers in these
  classes are a superset of what the extensions use.

* Updated references to the other helpers to use these classes

* Since DOMUtils or DOMCompat are not Parsoid-centric, it feels safe
  to provide extensions direct access to those utils classes. We could
  consider moving DOMUtils to the Core/Utils namespace if appropriate.

* In one case, I replaced the escapeNowikiTags helper that the Nowiki
  "extension" used with an inlined preg_replace.

* TODO: Add unit tests to ensure these utils don't break!

Timo Tijhof ce27a400e1 CiteHooks: Remove wgResourceModules check (redundant with isModuleRegistered)
The isModuleRegistered() method was introduced a few years ago,
when the load order in ResourceLoader was undergoing a change.

It used to be that hooks like were run first to register modules, and then
wgResourceModules was registered afterwards. This was reversed to disallow
mutating the config at run-time from foreign modules and to allow better
caching and error detection.

It's been several years since then, so this redundant check is no longer
needed. ServiceWiring.php in MW core for ResourceLoader always processes
config and extension.json first before this hook is called.

Subramanya Sastry 5e256b48aa Start untangling Parsoid internals from extensions
* In this patch, toDOM, fromDOM, and DOM postprocessor extension
  methods all get a ParsoidExtensionAPI object. These API objects
  are constructed at the appropriate times in the wt2html and html2wt
  pipelines.

* Got rid of direct references to SerializerState from fromDOM
  methods in extensions.

* Exposed generic serialization and wikitext escaping methods
  in ParsoidExtensionAPI for extensions to leverage. The implementation
  of these methods is partial and only supports current usage
  of extensions in Parsoid's repo. This will need to be fully
  fleshed out going forward.

* Stopped exposing wt2html options in toto and provided more specific
  convenience methods.

* Reduced direct access to the Env object in a few more places.

* Cite has code to inspect embedded HTML in data attributes of a node.
  Moved this code out of Cite into ParsoidExtensionAPI which reduces
  knowledge that extensions need. Unlike the other cleanups, this one
  is more of a convenience method since this code only requires
  knowledge of a publicly published spec. But, nevertheless an useful
  cleanup since it simplifies Cite's complexity just a bit.

* More followup work is needed.
  - before/after methods should be eliminated in favour of a config flag
    that implements the inline/block layout option. Once this is done,
    extensions will no longer need direct access to the SerializerState
    internal object.
  - Env exposure should be reduced.
  - Provide access to Sanitizer via ParsoidExtensionAPI instead of
    needing extensions to directly import it.
  - It should be possible to eliminate the need for extensions to know
    about DSR / DSR-shifting and do it automatically via some high-level
    conceptual flag.
  - It might also be possible to infer source offsets directly via args
    instead of passing that explicitly.
  - Should we provide a convenience helper class with access to all the
    src/Utils/* methods?

Thiemo Kreuz d80bd3ef97 Rewrite ErrorReporter for performance and separation of concerns
This patch is mostly moving code around without changing the behavior.
Exceptions:

* The ErrorReporter creates a <span> container. This was previously
parsed. The only benefit might be error checking and escaping. Rather
pointless. The code just created this HTML. With this patch, it is not
parsed any more. The unit test reflects this change. The output in
production will not change, as the parser tests show.

* Parsing of the message key (to detect it's type and id) is simplified
a lot, using explode. With this the code can, in theory, support more
types.

This exception was introduced very late in the patch I38c9929. It
already caused trouble. This here is essentially a revert. It restores
the previous behavior where this edge-case was silently ignored. The
worst thing that can happen is that appendText() creates an incomplete
entry in the $this->refs array, which will be rendered at the end. The
user can see it then.

As of now we are not aware of a code path where this would even be
possible. Still this does make the code *more* robust by not making it
explode, but give the user something they can work with.

"Conflicting" here includes the case where one of two <ref> with the

This error happens only when previewing an edit, because some of the

mode.

This patch is intentionally so small to make it easy to backport.

Thiemo Kreuz 013e1bfa90 Final clean-ups for a more consistent parameter order
* Always have an empty line between @param and @return to improve
readability as well as consistency within this codebase (before, both
styles have been used).

* Flip parameter order in validateRefInReferences() for consistency with
the rest of the code.

* In Cite::guardedRef() the Parser was now the 1st parameter. I changed
all related functions the same way to make the code less surprising.

* Same in CiteUnitTest. This is really just the @dataProvider. But I feel
it's still helpful to have the arguments in the same order everywhere, if
possible.

* Add a few strict type hints.

* It seems the preferred style for PHP7 return types is `… ) : string {`
with a space before the `:`. There is currently no PHPCS sniff for this.
However, I think this codebase should be consistent, one way or the other.

I refused to do this change previously because I don't like to mess
with Git blame if it's not really necessary. However, at this point all
code was moved around anyway.

I ended removing a comment that appears misplaced now, and doesn't help
maiing the code more readable. I like not having a dot at the end if
it's not really a sentence.

Personally I prefer having the newline. It creates a visible separation

first, optional later. Group and name together. Name and extends
together.

This depends on I4a156aa which fixes one of the last remaining trimming
issues. Outside of <references>, a <ref> </ref> with no other content
but some whitespace was already forbidden. But not inside of <references>.
This is relevant for appendText(). It should not be called with null, but
was because of the inconsistent behavior.

Thiemo Kreuz 1bd66081f7 Fix inconsistent error reporting for invisible content
This makes one of the last remaining edge-cases about non-empty, but
non-visible content (a <ref> that only contains whitespace) behave
identical to all other places. We already reported it as being empty
everywhere else, except inside of <references>.

Note that the test cases look like they are reporting the same errors
twice. But this is not the case:

The first set of errors is about <ref name="…"> inside of <references>
not having visible content. This should always be reported, even if the
<ref> got content from somewhere else on the page.

The second set of errors is when a <ref name="…"> *never* got any
content.

This patch will slightly increase the numbers of errors reported.

don't need to be callbacks.

* I'm also replacing all json_encode().

* To make the test code more readable, I shorten a bunch of variable
names to e.g. $msg. The fact they are mocks is still relevant, and still
visible because these variable names are only used in very short scopes.

Thiemo Kreuz df1a45b84c Fix incomplete cloning of the Parser::$extCite instance
This is what happens:
* The issue happens only on pages with two <ref> tags than share the
same name and group, but have conflicting text.
* This triggers a code path that renders an error message and calls
Message::plain() as well as Parser::addTrackingCategory(), which calls
Message::text().
* The Message class is asking for a new, fresh parser. This means the
parser is cloned and it's state cleared, while keeping stuff like
parser hooks.
* Cloning the parser triggers the ParserCloned hook.
* The hook handler clones the Cite instance stored in Parser::$extCite.
* PHP doesn't do deep cloning. Object properties are not cloned.
* Since I091a0b7 the internal state of the Cite class is extracted to
another class.
* This means the state is not cloned any more since I091a0b7.
* Now two Cite instances share the same state.
* At the end of the hook handler, the state is cleared, which also
clears the state of the original instance.

We will most probably solve this on master by getting rid of cloning
Cite. We propose this additional hotfix for the branch.

Thiemo Kreuz f92792f64a Fix bad localization of extended references numbers when reused
This adds a test for numbers like "1.2.0" that appear when an extended
reference (e.g. "1.2.") is reused multiple times.

The first separator is from the extended reference. We decided to never
localize it. However, the second seperator is from reusing a reference.
This was always localized. We believe this is a bug, but haven't fixed
it yet.

The test is documenting the status quo "1.2,0" with a comma. This kind
of makes sense, one could argue, because the "1.2" appears like this up
in the text, but the ",0" is a different indicator for a reuse, which
*never* occurs in the text.

Thiemo Kreuz 7c1849d7b0 Report both nested <ref> and <references> as an error
Before, this regular expression was looking for incomplete wikitext
like this:

<ref>unclosed
<ref>closed</ref>

With this change, wikitext like this will trigger the same error:

<ref>unclosed
<references />
incomplete</ref>

This should be much, much more rare. But I feel it's reasonable to mark
this as an error, instead of just rendering the broken inner tag in
plain text.

This patch also replaces `.*?>` with `[^>]*+>`. Both do the exact same.
Instead of doing an "ungreedy search for the first possible closing
bracket", which might cause backtracking, the new syntax consumes all
non-brackets before expecting one. This is guaranteed to never backtrack
(guaranteed by the extra +), and potentially faster because of this.

Thiemo Kreuz c5fe49ff11 Fail early on nested extends="…", if possible
This partly reverts Ied2e3f5. I haven't properly tested this before.
Rendering a bad extends (that extends a <ref> that's already extended)
not indented messes the order up and rips other extended <ref>s out of
context.

For now it might be better to stick to the previous, "magic" behavior:
Such an extends behaves like it is extending the *parent*, and is
ordered and indented as such. This is still not correct, but I feel
this is much better than rendering such a bad extends on the top level.

This patch also makes the code fail much earlier for a nested extends,
if this decision can be made already. In this case the error message is
rendered in the middle of the text (as other errors also are), not in
the <references> section.

Thiemo Kreuz a7ee7c9586 Refine and fix "unclosed <ref> detected" regular expression
This simplifies as well as fixes a series of issues with this regular
expression:

* Before, the wikitext `<REF><REF>` would not trigger the error, but
`<ref><ref>` would. Parser tags are case-insensitive, but the error
check was not.

* Before, the wikitext `<ref><ref name="<">` would not trigger the error.
That's a valid name. The error check should not stop just because it
found a `<`.

* Both the old and the new code do *not* fail with the wikitext
`<ref><ref</ref>` where the inner `<ref` does not have a closing `>`. I
was thinking about changing this, but figured it might be used as a
feature.

* The old code was not able to properly understand HTML comments,
<nowiki> tags and such that contain a line break. That caused
inconsistent and confusing error reporting in some cases, but not in
others. This change *reduces* the amount of errors this code produces.

* The old code was looking for "SGML tags" with names that could be
anything, not just alphanumeric characters. This allowed for strange
edge-cases like `<ref><>><ref></>></ref>` that have not been reported,
but should be. This change *increases* the amount of errors. However,
relevant edge-cases should be extremely rare.

Note the ++ avoids backtracking, speeding up the regex.

Thiemo Kreuz a7c4e14f42 Remove obsolete ParserBeforeTidy hook handler
I was able to track this code down to I093d85d from 2012, which was done
right after the ParserAfterParse hook was introduced. I believe the
redundant code path was left to keep the Cite extension compatible with
old MediaWiki versions that did not had this hook yet.

I also noticed this code path is most probably entirely redundant with
the current version of MediaWiki. The *only* thing this code does is
blocking the ParserBeforeTidy hook from doing the same thing a second
time if the ParserAfterParse hook was called before. But it does *not*
block any other compination, e.g. if the two hooks are called the other
way around, or the same hook twice.

In core, it looks like it is impossible for the ParserBeforeTidy hook
being fired without the ParserAfterParse hook being fired before. If this
is true, this is in fact dead code.

Thiemo Kreuz 54333c9bd6 Stop formatting "1.2" as "1,2" in languages like German
The new extends="…" feature is using numbers like "1.2". These should be
localized in languages like Hebrew that uses other symbols for the digits.
But the "." should not change.

The existing feature when a <ref> is reused multiple times does have the
same "issue". But it seems this is intentional, because it is covered by
a test. Note this is not visible in German, because German uses custom
labels "a", "b", and so on.

This patch also improves the so called "smoke" tests and makes one cover
numbers up to "1,10" for a <ref> that is reused that often.

If `extends` is encountered before the parent ref, we reserve the
sequence number and leave a placeholder to record the link between
ref name and number.  This is necessary to render a list like,
"[1] [2.1] [2]", or to use subreferencing when the parent ref is
declared in the references tag.

When a placeholder is encountered during references section rendering,
it means that the parent was never declared.

This relies on (Remex) Tidy to clean the incomplete HTML up.

This patch remembers the stripped </li> and adds it back.

This also makes sure the nested <ol> is closed, even if it was the
last element in the data structure.

Notice how this does not influence any test. I find this a bit
confusing. It looks like (Remex) Tidy is executed, even if the tests
are not marked as "html/php+tidy".

Thiemo Kreuz 0013943a4a Rewrite argument parsing and use for both <ref> & <references>
We realized the trim() are not needed. This does not leave much behind
in the existing refArg() method, except that it checks for unknown keys.

I tried a few strategies and ended using the pretty new possibility to
have keys in list(), as well as use [] instead of list(). Both is
supported since PHP 7.1.

Thiemo Kreuz 99d23ac841 Remove redundant attribute trimming
We noticed the group="…" attribute was the only one that was not
trimmed. Does this mean it was possible to have two groups "a" and
" a"? It turns out: no. This was never possible because the parser
already trims all attributes before calling this code.

I tried to come up with the worst possible test case, but it succeeds,
even with very old versions of this codebase.

I suggest to remove the extra trimming from this codebase and rely on
what the parser provides.

Note the content is special and *not* trimmed by default.

* Add missing @covers for the constructor.
* Simplify test setup by always returning a spy. All tests need it

Adam Wight 8453e3ecd7 Extract stack and state to a new class
Most of this state is used to manage interactions with other state,
and encapsulation allows us to hide data structures and access behind
self-explanatory function names.

The interface is still much wider than I'd like, but it can be improved in
future work.

There is one small behavior change in here: in the `follows` edge case
demonstrated by I3bdf26fd14, we prepend if the splice point cannot be
used because it has a non-numeric key.  I believe this was the original
intention of the logic, and is how the numeric case behaves.  I've verified
that when array_splice throws a warning about non-numeric key, it fails to
add anything to the original array, so the broken follows ref disappeared.

Thiemo Kreuz (WMDE) 5401fcd190 Revert a part of "Add missing test cases for follow="…""
This partly reverts commit 8e42a6ecdf.

The variabe $k as created by the foreach() loop is not necessarily
numeric, because the $this->mRef structure contains data both for
named and unnamed <ref>s. The array key is a (non-numeric) string for
named, and an integer for unnamed <ref>s.

array_splice() requires a position, not an array key.

Note that both implementations are wrong. The foreach() might return a
string $k, which makes array_splice() complain and do unwanted things.
The for() loop assumes there are count() array elements with integer
keys, which might not be true. Luckily this was not a problem, because
the isset() check would stop the (to long) loop eary enough.

A better rewrite as well as a test case for this will be added with
I3bdf26f.

Thiemo Kreuz ea6cea93ed Move bad dir="…" error reporting down to the renderer
… and make the error message for bad dir="…" shorter and more to the
point.

Now I understand why the error reporting was not done when $text was
empty: the error was actually appended to $text, which messes with
everything else that also works with the $text variable! This even
includes the API. This error message was exposed via the API. That was
certainly a bug.

With this patch, all error checking for the dir="…" attribute is now
done way down, when rendering the <references> section.

Note this also fixes a bug where the dir="…" was *not* rendered when
previewing a section.

Thiemo Kreuz 65c8967c32 Fix internal presentation of the dir="…" attribute
This fixes a whole bunch of inconsistencies:

* The dir attribute is now trimmed, as most others already are. This is
an actual user-facing change.

* The internal representation is now false in case the value was invalid,
not an empty string any more.

* Null means the attribute was not present. This is now always used,
even in the return values that are meant to represent an error state. No
existing behavior changes.

* The internal representation does not contain an HTML snippet any more,
but the raw value "ltr" or "rtl", or null. Note this might influence the
API, because the API actually exposes the internal representation.
However, we are pretty sure the API is not used anywhere. Even if,
exposing HTML code was most certainly an unwanted and unexpected effect
of the patch that introduced the dir attribute. This does make this a
bugfix, I would argue.

Subramanya Sastry ad229c1ac0 One more fix for T235656
It is about time to implement a generic fix for T214994 which will
capture the Cite-specific scenario we are tackling here in bits
and pieces. We have fragments of a T214994 solution spread in
Utils/ and here while tackling shiftDSR and convertOffsets
for Parsoid/PHP. So, someone needs to take a look at all these
pieces and implement the necessary abstraction.

As part of that, maybe we also need to revisit our embedded HTML
data-* representation so there is a uniform way to inspect these
attributes rather than every semantic element (template, extensions,
lang variants, media) choosing their own custom embedding scheme
which makes discoverability harder and error-prone.

Subramanya Sastry 2be3ab72c6 References.php: Use strlen not mb_strlen to count page length
* When a page is missing an explicit <references /> tag, we insert
  an implicit <references /> tag and assign it a zero-width DSR with
  a starting offset equal to the length of the page. However, now that
  we have byte offsets, that should have been strlen, not mb_strlen.

  This was causing incorrect DSR assignment on this implicit tag
  and causing trailing newline selser diffs on these pages.

Subramanya Sastry 167a28bbea Use PHPUtils::lastItem() over end() in more places
Tim Starling has indicated in couple different places that end(..)
is not preferred and he had implemented a private version of lastItem
in the PEG grammar code whereas PHPUtils::lastItem was recommending
use of end(..).

In this patch, I moved the implementation from the grammar to PHPUtils
and replaced end(..) with PHPUtils::lastItem in a number of places in
the codebase. We should discuss whether we want to use this helper
everywhere.

Resolved a couple of PORT-FIXMEs in the bargain.

C. Scott Ananian 7e444d6364 All extensions implement Extension; tags all implement ExtensionTag
Restructure ExtensionTag as an abstract class with default do-nothing
implementations of all methods.  So instead of Translate and LST
not implementing ExtensionTag::toDOM, they inherit the default
implementation which returns false, and that has the same effect.

The intention is to move SerialHandler::fromHTML and SerialHandler::before
into this framework as well.  Every "optional" method should have a default
implementation in the base class which returns false.

C. Scott Ananian b84b71af22 Gallery: shift TSRs in the DOM, rather than fibbing about srcOffset
Passing srcOffsets which don't actually correspond to actual regions of
the source wikitext cause problems in the token offset conversion code.
Instead, parse the wikitext as itself, then adjust the TSRs in the DOM
tree.

Since Gallery isn't ported to PHP (yet), update the
automatically-generated Gallery/index.php.  The newly-added
ContentUtils::shiftDSR() was ported, however.

Subramanya Sastry 720f1db084 Fix exception handling: Don't catch exceptions and suppress them
* Now that we are in sync land, we don't need to catch exceptions
  and log error messages at multiple places. Let them bubble up
  to the top.

* I noticed this was actually getting in the way of debugging because
  with $env->log unimplemented, I was only getting very generic
  failures instead of the root cause that was being suppressed
  and unlogged.

* There are still a couple of places where we have generic Exception
  catching in place where it does make sense currently. For example,
  we aren't interested in what caused a templatedata fetch to fail.
  We simply fall back to regular serialization - the rationale here is
  that it is better to emit a transclusion without the preferred formatting
  (but syntactically correct) instead of losing the edit altogether.

* Minor unrelated fix in Cite/Ref.php: Use !isset() instead of empty()

  to how we think of undefined.

* Flipping the polarity of the flag to sealFragment makes the
  semantics easier to reason with and where !empty(..) applies
  more naturally to it.

not null.  Audit our uses and try to either explicitly use `|| ''` (which
will ensure that PHP behaves the same was as JS) or use `hasAttribute`
to explicitly test for the presence of the attribute.

Changes have also been ported to PHP from JS.
Also added src/Wt2Html/PP/Processors/AddMediaInfo.php which was missing.
