The most common cleanup required by switching to tidy output was adding
missing <p>-wrappers to the last item before <references/>.

While working on the patch I4303642 I was worried about the line
array_pop( $this->refCallStack )
in the rollback code. Since the patch changed the position of follow
elements in the stack, an array_pop() would pop different elements.
It turns out this is impossible. Rollbacks are only done for <ref>
elements inside a <references> tag, immediatelly after reaching the
closing </references>. It's impossible to use follow="…" inside
<references>. It will not be added to the stack, and therefore not
rolled back.
Even if the edge case would be possible, the *old* code that placed
follow elements on the *other* side of the stack would have been
wrong then.
The test cases in this patch try to hit this edge case, and are
expected to not be able to do so.

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).

This removes a few tiny pieces of code, and a large chunk related to
incomplete follow="…" attributes (see T240858). It turns out we don't
need to insert elements at the top of the ReferenceStack::$refs
array, because this array is reordered anyway in
ReferencesFormatter::formatRefsList()!
Incomplete follow refs don't have a number, and are ordered to the top
because of this, as before. This doesn't change with this patch.

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.

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.

These create bogus output, depending on the surrounding wikitext the
<ref> tag is used in. For example, this example wikitext:
* Example.<ref name="1">a</ref> More text.
… will be rendered with the "More text" sentence wrapped on the next
line, outside of the list. However, this does *not* happen in many of
the localizations, e.g. German, because many Tanslatewiki translators
did not copied the bogus \n. Why should they.
TL;DR: These newline characters either do nothing, or destroy the output.
In both cases the proper fix is to replace them with spaces.
Some of the test cases touched in this patch demonstrate the issue.

… if possible. In most cases it's possible to use the real object, and
reach into it's private parts via TestingAccessWrapper. This is almost
the same as using a mock, but I feel it's much more "light-weight".
The main change is that there is no strict assertion any more for the
number of ReferenceStack::pushInvalidRef() calls. Before this was mixed
into the same array as the valid references, as elements set to "false".
I think the test is as valueable as before without this extra check. If
the rollback stack works or not is already covered by other tests.

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

a name specifies if a <ref> is a top-level or a sub-reference. This can

book as a whole, only references that point to individual pages. The

I feel this is a little better than before. It looks like we never need
to *replace* a text that existed before.
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.

The name of the base class in tests is guaranteed to only occur a
single time in a file. There is not much value in making it relative,
and requiring it to appear in the use section. Especially because it
is in the root namespace.
This reflects what I once encoded in the sniff
https://github.com/wmde/WikibaseCodeSniffer/blob/master/Wikibase/Sniffs/Namespaces/FullQualifiedClassNameSniff.php
I wish we could pick this rule and use it in our codebases. But it
seems it is to specific and can't be applied on all codebases, hence
it can't become part of the upstream MediaWiki rule set. At least not
at the moment.

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.

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.

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.

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.

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.

I noticed a possible issue related to the $this->refSequence counter
in the patch Ida9612d. Some of these counters might get messes up, but
there was never a test that checked what will happen to the *next*
reference then.
I checked the test cases in this patch with a very old version of the
codebase.

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.

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.

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.

It only applies some early steps of the parsing process, e.g. expanding

* This fixes the refArg() function. If there is nothing wrong with the
follow="…" attribute, it should not return null.
* However, *everything* is false if an unknown error (e.g. an unknown
attribute) occurs.
* A trivial check for `if ( $follow )` is fine because all keys are
guaranteed to not be the string "0".

… 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.
Change-Id: I4ab0cb510973ed879c606bfaa394aacc91129854
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.

This patch does intentionally not touch any file name. Some of the

The use case we care about is this:
<ref extends="some_book"> </ref>
It doesn't make sense that works, but the following doesn't:
<ref extends="some_book"></ref>
We decided that both need to behave the same.
For consistency this patch is applying the same change to all references,
no matter if they use the extends attribute or not. This is an actual
change and might make existing wikitext render differently. However, I
would like to argue that all wikitext that was using this was broken. The
effect of a <ref> </ref> with some whitespace is that the <references>
section at the end of the article will contain – well – an empty footnote.

1. Most existing CiteTests can be unit tests. They run so much faster
this way.
2. I modified some test cases to cover all trim() in the code.
3. The strict type hint in CiteHooks is removed because the parameter
is not used. Having a hard type hint for what is effectively dead code
makes the code more brittle for changes done outside of this codebase.

To be honest I don't get why this lazy registration was done in the
first place. None of the 4 other hooks should ever be called before
the ParserFirstCallInit hook got called.
Also, under which circumstances can the ParserFirstCallInit hook be
called more than once?
Both scenarios would be wrong, as far as I'm concerned. Either I'm
missing something, or this code can indeed be simplified. Maybe it was
something to make it more compatible with older MediaWiki versions?
The only reason I can think of is: in all situations that do not
involve a parser, having the 4 extra hooks registered is pointless.
Does this waste space and/or runtime in the $wgHooks registry?

* That unimplemented stuff is marked with TODOs.

We can resolve this bug by either replacing the bogus "return false"
with the intended "return [ false, … ]". Or rely on the code a few

many parameters ($cnt is not 0 then) are present. The tests prove both
solutions are equally valid.

This change does have two consequences:
1. A few more whitespace characters act as separators. This should not
have any consequence in real life situations, and is mainly done to
make the code easier to read and less surprising.
2. Sequences of two or more whitespace characters previously resulted
in partly *empty* results. This was a potential source of errors. The
additional + fixes this.

Change-Id: I89a4f8ba24b867f2d5ccdc2bf9a4312ab9b385a9
This is based on the popular 'count' parameter from Template:Reflist on
English Wikipedia, which has also been adopted by many other wikis.
That template's 'count' parameter allows maximum flexibility on a per-
page basis. This was important because the template can't know how many
references the list will contain. Users typically manually add (and
later, increment) the 'count' parameter when the list exceeds a certain
threshold.
The template currently sets an exact column count (via the CSS3
property `column-count`).
This patch improves on that by instead using the closely related CSS3
`column-width` property. This automatically derives the column count
based on the available space in the browser window. It will thus create
two or three columns on a typical desktop screen, and two or no columns
on a mobile device.
The specified width is the minimum width of a column. This ensures that
the list is not split when rendered on a narrow screen or mobile device.
It also hooks into the raw list before parsing and adds the class only
when the list will contain more than a certain number of items. This
prevents very short lists from being split into multiple columns.
Templates like Template:Reflist on English Wikipedia currently are not
able to set inline styles on the list element directly, which is why
they set it on a `<div>` wrapping the `<references />` output. Because
of this, the feature of the Cite extension must not be enabled at the
same time, as that would result in both the template's wrapper and the
references list being split. The end result would involve sitations with
three columns split in four sub-columns, creating a complicated mess of
nine intermixed columns.
To provide a smooth migration for wikis, this feature can be disabled by
default using `$wgCiteResponsiveReferences = false`. Each individual
template createing reference list can then be migrated, by removing the
wrapper column styles and instead settting the new "responsive"
attribute, like so: `<references responsive />`.
Once any conflicting templates have been migrated, the default for the
wiki can be swapped by setting `$wgCiteResponsiveReferences = true`.
If wikis wish for some templates to keep their custom column splitting
behaviour, templates can also opt-out by setting `responsive="0"`, which
will make sure that it will keep behaving the current way even after the
feature becomes enabled by default for the wiki.
In summary, when disabled by default, pages can opt into this system
with `<references responsive />`. When enabled by default, pages can opt
out of the system with `<references responsive=0 />`.
* Deprecate cite_references_prefix/cite_references_suffix.
This message is rarely used and opens up compatibility hazards.
It was already removed by Parsoid, but the PHP implementation
still had it. It's typically used to add inline styles to the
wrapper which is more appropiately done in Common.css (or
obsoleted as part of the skin or Cite extenion itself nowadays
depending on what style in question).
It was also a HTML-style message with separated open and close
segments, which is an anti-pattern in itself.
* Declare module target explicitly and include mobile. The absence of
this stylesheet caused subtle BiDi/RTL bugs on mobile.
