The ext.cite.referencePreviews module will transparently replace the
ext.popups.referencePreviews module after this patch. Configuration
stays in Popups for now, we can migrate it in later work.
CSS classes may be renamed in the future but this will be handled
separately since it could be a breaking change for on-wiki
customizations.
A lot of fancy footwork happens in this patch to emulate a soft
dependency on Popups. This mechanism doesn't exist explicitly in
either ResourceLoader or QUnit, so lots of workarounds are used, to
conditionally load the module and to dynamically skip dependent tests.
renderer.test.js is fully skipped for now, but can be wired up in
later work.

The information read from the …cite-tool-definition.json files is
effectively user input, even if only interface administrators can
edit it. Usually we carefully validate user input. But as of now
this code starts failing with all kinds of uncatched errors.
* An entry with no name, an empty name, or a name that's not a
string will cause all kinds of undefined behavior.
* An entry with an empty title results in an invisible button.
* A missing message results in a technical <…> placeholder, even if
the name is usually a sensible fallback.
Note that hard-coding titles as plain text strings in the ….json
file was already possible.

The message was part of the original patch that introduced the group
feature in 2009, see https://phabricator.wikimedia.org/rECIT75004e33.
Notice how there was never a test scenario for this message. A test
was added in 2020 via I07738cc.
The message appears only in a rare edge-case when a group is entirely
unused in the text, and only when the group is not empty. The shortest
possible example is:
<references group=g>
<ref group=g name=a>a</ref>
</references>
Just adding something unrelated like `<ref group=g>x</ref>` to the
text changes the error message. Now the group is "used". But this
notion is confusing to begin with. References can be part of a group,
and we can use references, but we can't use groups as if they are a
separate entity.
A better error message already exists.
Notice how this special error message doesn't appear anywhere in the
Parsoid code path. That was already using the other, more generic
error message.
Bug: T269531
Change-Id: I63f663d76e45e6c3d664f145d9a564ee00ff53cd
This is about the error message that currently says:
»Cite error: <ref> tag with name "a" defined in <references> has
group attribute "" which does not appear in prior text.«
This is a special error message that appears only when a group name
does not appear anywhere in the text. In all other cases a simpler
error message is shown:
»Cite error: <ref> tag with name "a" defined in <references> is
not used in prior text.«
While the first error message is not wrong in the edge-case
described in T269531, it's very confusing for a multitude of
reasons. For example:
* There is no group attribute in the wikitext.
* Just adding something completely unrelated like `<ref>x</ref>` to
the text shows the other error message.
The reason for this behavior is that the assumed default is an empty
`group=""`. The error message changes the moment any other <ref> in
the same group appears in the text vs. when the group is entirely
unused.
We can probably remove this error message entirely, but should at
least not use it when there is no group.
Notice how the Parsoid code path was already using the other error
message.

This is another improvement after I7390b68. Status objects are made
to keep track of multiple errors. The only difference is: The merge
method skips duplicates when the message and all parameters are
identical. This causes a minor user-facing change. One of the
shortest possible examples is:
<references>
<ref />
<ref />
</references>
This showed two identical, indistinguishable error messages before,
but will only show one now. We argue this is fine. The duplicates
are confusing and of (almost) no value to the user. In case the
information is relevant the correct solution is to make the error
messages distinguishable, or introduce a message like "multiple
<ref> tags defined in <references> have the same error". This is
something for a later patch, if needed.

This patch is not blocked on anything according to CodeSearch:
https://codesearch.wmcloud.org/search/?q=cite_references%3F_link_prefix
According to GlobalSearch there are 2 usages we need to talk about:
https://global-search.toolforge.org/?q=.®ex=1&namespaces=8&title=Cite.references%3F.link.prefix.*
zh.wiktionary replaces "cite_ref-" with "_ref-", and "cite_note-"
with "_note-", i.e. they did nothing but remove the word "cite". This
happened in 2006, with no explanation.
ka.wikibooks and ka.wikiquote replace "cite_note-" with "_შენიშვნა-",
which translates back to "_note-". One user did this in 2007,
16 seconds apart.
It appears like both are attempts to localize what can be localized,
no matter if it's really necessary or not.
https://zh.wiktionary.org/wiki/Special:Contributions/Shibo77?offset=20060510https://ka.wikiquote.org/wiki/Special:Contributions/Trulala?offset=20070219
Note how one user experimented with an "a" in some of the edits to
see what effect the change might have, to imediatelly revert it.
The modifications don't really have an effect on anything, except on
the anchors in the resulting <a href="#_ref-5"> and <sup id="_ref-5">
HTML. It might also be briefly visible in the browser's address bar
when such a link is clicked. We can only assume the two users did this
to make the URL appear shorter (?). A discussion apparently never
happened. Bot users are inactive.
Both pieces of HTML are generated in the Cite code. Removing the
messages will change all places the same time. All links will
continue to work. The only possible effect is that hard-coded
weblinks to an individual reference will link to the top of the
article instead. But:
a) This is extremely unlikely to happen. There is no reason to link
to a reference from outside of the article.
b) Such links are not guaranteed to work anyway as they can break
for a multitude of other reasons, e.g. the <ref> being renamed,
removed, or replaced.
c) Even if such a link breaks, it still links to the correct article.
There is also no on-wiki code on zh.wiktionary that would do anything
with the shortened prefix:
https://zh.wiktionary.org/w/index.php?search=insource%3A%2F_%28ref%7Cnote%29-%2F&title=Special%3A%E6%90%9C%E7%B4%A2&profile=advanced&fulltext=1&ns2=1&ns4=1&ns8=1&ns10=1&ns12=1&ns828=1&ns2300=1
I argue this is safe to remove, even without contacting the mentioned
communities first.

This fixes a minor issue introduced in I294b59f. Two identical
dir="…" with different capitalizations should not be reported as an

Turns out the implementation in the Cite extension doesn't care

normalization as early as possible. This is slightly different in
the Parsoid implementation.

* Since Cite development happens in two repos (here and the Parsoid
repo), integrated tests ensures that changes don't fall too far
out of sync.
CI runs Parsoid-integrated-mode tests in extensions repo with the
vendor-released Parsoid.
Parsoid CI runs Parsoid-standalone-mode tests in the Parsoid repo
which also has a copy of the citeParserTests.txt file found here.
But, that CI run uses the Parsoid patch itself.
This difference makes for unnecessrily laborious test syncing
while making changes to the two repos. It is manageable for one-off
changes but when making lots of updates that changes tests a lot,
this quickly becomes painful.
* For now, we can break this coupling temporarily by disabling
Parsoid-integrated-mode test runs. This simplifies the test syncing
by letting patches in Cite repo to be merged in a chain and then
doing a single test sync to the Parsoid repo (otherwise, Parsoid's
CI will be broken since the html/php sections in Parsoid's cite
test copy will be out of date).
* Filed T354215 to move Parsoid's Cite implemntation to this repo
which eliminates this complexity altogether.

Same arguments as in Iafa2412. The one reason to use more detailled
per-method @covers annotations is to avoid "accidental coverage"
where code is marked as being covered by tests that don't assert
anything that would be meaningful for this code. This is especially a
problem with older, bigger classes with lots of side effects.
But all the new classes we introduced over the years are small, with
predictable, local effects.
That's also why we keep the more detailled @covers annotations for

I played around with a few options (see patchset 1) but ended
introducing new terminology:
* "Backlink" describes the ↑ button down in the list of <references>
that jumps back up into the article. The code was already using
"backlink" in some places.
* "Backlink target" is the id="…" attribute up there, visible as the
typical [1] in the article.
* I use "jump" to describe the idea that clicking the [1] jumps down
to the full reference.
* "Jump target" is the id="…" down there in the list of <references>.
* "Jump link" is the same id, but encoded to be used as the href="…"
attribute when clicking the [1].
I hope this makes sense. Suggestions welcome.
Another benefit is that "normalization" is really only normalization
now, not any URL and/or HTML encoding.

This moves the actual parsing down to be done much later in the
process. This won't make any difference in production but makes it
easier to refactor the code further.
Note I tried to use a StatusValue object but couldn't because it
merges seemingly identical messages, while the plain array is fine
with containing duplicates. There is one parser test that covers
this. While we could change this it needs discussion and most
probably a PM decision.

The "parser marker" placeholders are case-sensitive, e.g. for a tag

was really just a mistake.
The error is as old as this code is. Added in commit 75004e33 in
2009.
Note we shouldn't use /i at the end because the marker itself should
not be case-insensitive. Only the tag name.

exactly about this part of Cite (nested tags) anyway.

Two problems:

are not independent from each other. This problem can be seen in
CiteTest.
2. Some test cases in testValidateRef don't test what you think.

This implies that the is decoded and re-encoded with a
slightly different entity encoding. (Note that and  
and   are all the same character.)
Also note how there is only an underscore in the href="…", but the
non-breaking space is gone. This is identical to what happens in
links and headlines. Try for example [[a _a]]. Multiple
underscores, non-breaking spaces, and normal spaces will be

This patch does two things:
1. The "normalization" function was never only doing normalization,
but also all the necessary HTML encoding. This is now more visible
and split into two separate functions.
2. To make this easier we change the order slightly. Because of this
the normalization step must now consider spaces. Before spaces have
been converted to underscores by escapeIdForLink.
The results are all the exact same as before.
This is split from I5a64ac4 to make that easier to review.

This parser test is a bit obscure, in my opinion. We added it in

places.
We continued reworking the code since then. By now it's effectively
impossible to "accidentally" get thousand separators. The
problematic methods from the Language class are not even accessible
any more from this code.

This reverts a very tiny part of Ib3fdc89 from 2 weeks ago. The
reasons are explained in Ib3fdc89. Short version:
* The ->parse() calls have drastic performance implications.
* Allowing wikitext and HTML in this message also makes T321217

The new message "cite_reference_backlink_symbol" is kept and still
used in the UI. Just not in these two messages any more. This is a
minor redundancy we want to get rid of at some point. But it's not
critical for the moment. This will be done as part of T321217.
Nothing will break on the wikis. Some wikis have customizations for
"cite_references_link_one" and "cite_references_link_many" in place.
This will continue to work as before Ib3fdc89.

This is a mistake that exists in this codebase for who knows how
long.
Cite mis-uses the messaging system a lot for internal things we still
want to customize somehow, but are not labels that will ever be shown
on the screen. The prefix/suffix messages in this patch are meant to be
part of the HTML in id="…" attributes. Prefix/suffix must be a static
plain text strings. Using e.g. {{GENDER}} or {{PLURAL}} in these
messages is not even possible because there is no $1 parameter to use.
Note how all other similar messages already use ->plain().
A few wikis override these messages, but stick to the plain-text
convention, as they should:
https://global-search.toolforge.org/?q=.®ex=1&namespaces=8&title=Cite.*reference.*fix
This will continue to work.
This has minor performance implications. Fetching these messages is
faster if we can skip transformations.

The WikiEditor extension has a button and some help text that
is only applicable if the Cite extension is enabled. Move
that (with some modifications) to the Cite extension instead.

This is mostly because recent IDEs can understand createMock() quite
good. We usually don't add such hints every time we use createMock().
We would have a million of them. ;-)

html/php sections are added since otherwise it complains that the
"Test lacks html or metadata section on lines"

WebdriverIO has dropped support of sync mode, hence changed to async.
Update npm packages: @wdio/*, wdio-mediawiki
because async mode needs at least @wdio v7.9.
Remove npm packages: @wdio/dot-reporter and @wdio/sync.

IDEs like my PHPStorm trim spaces from the end of the line. It looks
like they are not relevant for the test and can as well be removed.

The best practice for message keys is to use dashes, not underscores.
This codebase is quite old and traditionally uses underscores. I
think we can make it flexible enough to work with both.

Since parser test requirements are per-file, move the smoke test which
requires `{{#ifeq}}` (from [[mw:Extension:ParserFunctions]]) into its
own file and define the requirement properly in the file header.
That avoids spurious parser test failures if developers don't have
the ParserFunctions extension installed locally.
