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.

Perform the validation in validateRef, and display a new error message for
broken "follow" refs. This changes existing behavior, where broken folow
ref content is arbitrarily displayed at the top of the references list and
no error is rendered.
Thanks to weasely wording, the new error can later be reused for "extends"
errors.

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.

This resolves another TODO. Since this is an intentional limitation in
the design of the feature, I find it pretty signigicant to give it it's
own error message.
Note that the text does not need to be perfect, just good enough for now.
We will review all error messages later via T238188.

"Conflicting" here includes the case where one of two <ref> with the
same name does not have an extends attribute. The first occurence of
a name specifies if a <ref> is a top-level or a sub-reference. This can
not be changed later.
This patch changes multiple existing test cases. I checked all of them
in detail and confirmed the behavior is fine. The error reporting is
better or at least equally good in all cases.

The goal of this patch is to not change any behavior, just make the
code less nested and less complicated.

The difference between the two is that isOK() only reports "fatals",
while isGood() also reports "warnings" and "errors". I believe we
*want* to report all of these the same way.

This error happens only when previewing an edit, because some of the
validation in Cite::validateRefInReferences() is disabled in preview
mode. Unfortunately this codebase was never properly tested in preview
mode.
This patch is intentionally so small to make it easy to backport.
Tests will follow.

* 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.
Change-Id: I91d232be727afd26ff20526ab4ef63aa5ba6bacf
There is currently no strict CodeSniffer rule for this. I think we
need to have one sooner or later. Anyway, what I find important is to
have a consistent code style in one codebase.
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.
Change-Id: Id1d4f43277c69080c512c1a5ceff4c948bfa05be
In the end I don't care much if we agree on having this newline, or
not. What I care about more is that this codebase is consistent.
Personally I prefer having the newline. It creates a visible separation
between what "goes in" and what "goes out" (@throws and @return).

The rollback feature was not able to properly restore a __placeholder__.
That's why a specific use case was behaving different. This already
worked just fine:
<ref extends="a">…</ref>
<references>
<ref name="a">…</ref>
</references>
But this didn't, even if it is the exact same from the users
perspective:
<ref extends="a">…</ref>
{{#tag:references|
<ref name="a">…</ref>
}}

Note this leaves *another* bug behind. When a <ref> is properly reused
by name="…", and the content is fine (either missing or identical),
possibly conflicting extends="…" attributes are currently entirely
ignored. However, this is already much better than what happened before.

The rollbackRefs function no longer needs to "know" details about
how to turn a refCallStack item into a redo item. This is better a
responsibility of the subroutine, where the items are unpacked.

One of the most significant changes is when I noticed that the $group
can never be null. We set it to DEFAULT_GROUP before. That's an empty
string.
I'm not very happy with the two @phan-suppress-next-line. Is there a
better way to fix these lines?

Since I3db5175 the ParserCloned hook handler does not rely on cloning
the Cite object any more. There is no cloning any more. This is dead
code and we could remove it. Just to be sure I propose to keep the
method, but let it throw an exception.

These should be impossible conditions, we don't want to continue with
processing.
I hate this patch, it's a temporary workaround until someone rewrites
or replaces the rollback logic, for example with a two-pass parse.

The main benefit is this nifty call: `$this->rollbackRef( ...$call )`
To make this possible, the minimal change I needed to do was to move
the two $argv and $text arguments to the end.
I also tried to order all other arguments as good as I could: Required
first, optional later. Group and name together. Name and extends
together.
All this is private implementation and should not affect anything.
Change-Id: I7af7636c465769aa53122eb40d964eabdd1289ba
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.
Change-Id: I38c9929f2fa6e69482e45919e2f8dbf823cb1c8b
Note that this patch changes behavior, an invalid "dir" will result in
a cite reference at the point where the <ref> is declared rather than
in the references section. This is consistent with other errors.
Bug: T15673
Change-Id: Id10db40aa0b391f2f1d9274aa09d22a7278d65e3
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.

* Use the Html class to safely create HTML code.
* $this->referenceStack can not be null any more.
* $this->inReferencesGroup is not needed during output, only when
parsing tags.
* Replace ReferencesStack::getGroupRefs() as well as deleteGroup()
with a combined popGroup() that does both things.
* Extract the code responsible for the "responsive" behavior to a
separate function.
* Some TestingAccessWrapper are not needed.

In these cases, an expression is either true-ish or null, so we can use
the implicit boolean cast to test.

Finishes breaking the circular reference between Cite and Parser.
This patch also demonstrates how evil it is to allow the error reporter
to be called from anywhere, and have side-effects. At least it's explicit
now.
Also fixes a bug where the inner error message would not be in the
interface language.

Only create a Cite object if we need one. Never clearState, just
destroy and recreate later.
This makes it less likely that we leak state between parsers, and
saves memory and processing on pages without references.
It's also preparation to decouple Cite logic from state.

* All classes are in a Cite\ namespace now. No need to repeat the word
"Cite" all over the place.
* The "key formatter" is more an ID or anchor formatter. The strings it
returns are all used in id="…" attributes, as well as in href="#…" links
to jump to these IDs.
* This patch also removes quite a bunch of callbacks from tests that
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.

Fixes a bug introduced in Icf61c9a27fd, which would cause a parser
cache split any time the Cite extension was initialized. The
`setLanguage` interface is regrettable, but I'm hoping it will only
be around temporarily.

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.

This class renders a <references> tag and everything inside. The
previous name sounds like it is responsible for rendering the contents
of a <ref>…</ref> tag. I mean, the class contains a method that does
exactly this. But this method is private.

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.

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.

The concept "key" already exists in the structure handled by this

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.
