When a thumbnail in portrait-mode is narrower than the 200px
expected width, the SVG clip-path should be shifted on the x-axis
in order to align with the thumbnail image.

We run into this issue already one time, see Ifb5fe89 (T214710). The
exact same applies here.
The effect of this bug is that for certain references (typically ones
with a colon character in their name) the "jump down" link will be
broken.

During story time on 2019-03-12 it was decided to consistently talk
about "References" in all messages. Main motivation is that this is
the term the community is most familiar with, and it is also the term
that is used in reference section headings most of the time.

The method itself has not much to do with gateways as such, it's
more about the general preview type selection. Since the preview
types "live" in the model, I thought it might good to move it there.
Doing that the "original" getPreviewType method in the model was renamed
to avoid conflicts. If I get this right, that method is quite specific to
page previews, since it processes the output from the TextExtracts API-
request. - Therefore I also removed the TYPE_REFERENCE there, because this
code path will never be reached with that type afaik.
Inspired by the comments in Id1fa7dad59d8fe80bc60c1e2d7c3fb4087e52d1f and

This happened one time before and was fixed via T212419. It now came
back after I2670331, a patch for T214861 that made the title parser
accept more links than before.
This patch implements a decision tree that goes as follows:
1. If it's a link to another page, it can't be anything but a page
preview, as having a peek into another page is effectively the
definition of a page preview.
2. Otherwise it's probably a reference preview, but only if:
* It's a link with a jump mark.
* The link is actually marked as being a "reference".
* Reference previews are enabled.
3. If neither of these definitions fit, do nothing. Note this is not
"hiding errors" we would be able to fix in this code. There are many
ways to manually arrange wikitext in a way that it looks like one or
the other, without fulfilling all requirements. Unfortunately the
user who would see error message or dysfunctional popups would not
be the same as the user who wrote such wikitext.

use "classic" JavaScript, but document it with the benefits TypeScript

All the lower-case jQuery this patch happens to touch have been placed

I'm not sure where the `…: false` comes from. I assume it is a mistake

The definition of "self-link" in this context is an <a href="…">
element that points to the exact same URL as the current document's
location, excluding a possibly different #… fragment. This is typically
the case when the <a> element does not contain a full URL, but something
like href="#fragment". JavaScript's HTMLAnchorElement.href getter
automatically expands this to be a full URL.
Example:
var a = document.createElement( 'A' );
a.href = '#test';
console.log( a.href );
Notes:
* This new code assumes the wgPageName setting properly reflects the
page name requested via the current document's location. Core does
give us this guarantee.
* The only URL element that is intentionally not compared is the
protocol.
* This accidentially fixes T215899 as well, because the namespace check
is now bypassed for self-links (as it should).

This patch also removes misplaced empty lines at the beginning of a

don't, but I suggest to be consistent about this.

According to the standard.
Note: In a previous patch I removed the <?xml …?> line. This conflicts
with what https://www.mediawiki.org/wiki/Manual:Coding_conventions/SVG
suggests. However, I think the removal is ok in this particular case
because this file will never be shown as an image, and never be shown
standalone. Instead, it will be inserted in the documents DOM. The XML
header doesn't matter anyway then.

I tested this with all 16 possible combinations:
* The pointer can show up in all 4 corners.
* The popup can contain a thumbnail or not. The code for the pointer
is very different then, because the SVG masks are only relevant in
this scenario.
* The thumbnail can be tall or not.
* I even tested tall popups without a thumbnail. This is a combination
that is impossible in production scenarios.
I found 3 issues. This patch fixes 2 of them:
* The pointer is misplaced in the bottom-right corner when the popup
does not have a thumbnail (as reported in T215194).
* The pointer is misplaced in the upper-right corner when the popup
shows a thumbnail.
* The pointer in the upper-right corner is gray instead of white when
the popup is tall, but does not show a thumbnail. As this is not
relevant in production, I did not fixed it.
It seems both misplacements are because of the same reason: For some
reason, calculations are done based on the assumption the popup would
be 300px wide, but it is 320px wide.
Note I did not just added 20 everywhere, but manually alligned the
pointer triangles so they are placed exactly the same distance from
the corner as in the three other corners.
Note I did not tested this (yet) in RTL scenarios.

We discovered a bunch of possible solutions (see previous patch sets),
including replacing the `$( document )` selector with a more specific
one. That idea does not pass the linter.
Very late I realized the original selector starts with
`#mw-content-text`. This heavily limits where popups are allowed to
appear: really only in the main text content area.
We should limit reference popups to the exact same scope.
This fixes the issue described in T215195. Before, the content of the
popup was covered by the selector. Reference links *inside* the popup
would trigger another popup, which makes the current popup disappear.
Now the popup itself is not covered by these event handlers any more.

There are a few cheap checks done before this regular expression is
even needed, most notably the check for a pretty URL (without query
parameters). Since the vast majority of links processed by this parser
are pretty, I believe this optimization is worth it.

This is now possible since the render functions return jQuery objects.
All this code is exclusively used in the pagePreview.js file, and

This CSS class is used by the regular wikitext content area, and used
by certain CSS selectors (e.g. the external web link arrow).
The DOM structure for each popup is (intentionally) created outside
of this scope, at the end of the current page's body. This works
great for page previews because the do *not* want to share any styles
with the rest of the page. But reference previews want to do this.
In this patch I also remove the inner <span>. It was misplaced (note
the name) and resulted in block elements nested in an inline element.

As discussed in Iaadcce9. This does have a few benefits:
* Less code in the already pretty big render.js file.
* The code setting the target attribute is much closer to where it
belongs: in the file that specifies how the content of a reference
popup should look and behave.
* The class name "mwe-popups-extract" is not mentioned in two different
files, but in the same.
Note this changes the signature of this src/ui/templates/… file to not
return an HTML string any more, but a jQuery object. The other templates
still return strings. I believe this is fine, and not that much of a
difference anyway. The signatures don't need to be identical. And the
jQuery object still represents the exact same HTML as before.
If it helps we could change all templates/… signatures accordingly.
Could be done in this or a separate patch.

This solves the (I believe) only regression we introduced: A bad fake
reference like <span class="reference">[[Other article#Section]]</span>
showed a page preview for the "Other article" before we introduced
reference previews, but would have shown nothing after I9ec57e0.
Checking if the link is a self-link solves this and possibly more related
issues. Only self-links can point to a footnote on the same page.
Manually created fake-references like
<span class="reference">[[#Section]]</span> still have a chance to show
nothing in case the manually created HTML does not strictly follow the
expectations in the gateway. There is not much we can do about this. We
should not accept any arbitrary HTML but need to make at least *some*
assumptions.

This installs a series of safety nets:
* The selector [href*="#"] skips links without a fragment.
* It's still possible that a fragment exists, but is empty.
mwTitle.getFragment() checks this.
* The gateway does not assume the element exists, but checks this first.
If there is no such element, the gateway aborts the request in a way
that no error popup is shown. This is currently only possible with the
`{ textStatus: 'abort', xhr: { readyState: 0 } }` response as seen in
this patch. We might need to introduce a new, more clean way to silently
quit a fetchPreviewForTitle() call.
* The test for the reference gateway finally covers the scraping code.

I believe it is impossible or extremely hard to actually abuse any of
these places. All these data are not extracted from the current page, but
delivered either by MediaWiki's api.php or a RESTful endpoint, as
configured via $wgPopupsGateway and $wgPopupsRestGatewayEndpoint. A
possible attacker would need to write it's own endpoint (which must either
run on the same server or somehow ignore the CSRF token), and set the
value of mw.config.values.wgPopupsRestGatewayEndpoint on the client to
this endpoint – which requires just *another* attack vector to be able to
do this.
It's "the right thing"(tm) to escape all this anyway.

This will affect all links, including [[Other page#Fragment]] for
example. But it will not have much of an effect there. The mw.Title
class is able to understand strings like "Other page#Fragment". All
old code calls title.getPrefixedDb() on the result. This will *not*
include the fragment. Only the new code will use title.getFragment().
I made sure this does not affect regular page previews, even when the
link is something like [[Other page#Fragment]].

I guess both is fine: either having the default in the gateway (as it
was before), or in the renderer (as this patch proposes). I, personally,
feel better with having it closer to where it is needed. This way it's
not possible to accidentially deliver a model object with an empty title.
The renderer will catch this.
At the moment we don't know exactly how we will fetch other titles (e.g.
"Book").
This change is split from I15611a4 where it was a little misplaced.

But it's many more characters that need escaping. See

Note this patch misses a test. I already uploaded I9ec57e0 to fix the
currently incomplete tests. But I can't make it work. How do I create an

This is documented at http://usejsdoc.org/tags-type.html, but not in many
other places, especially not in the JSDuck documentation.
The {!…} syntax means "can not be null". This is the default anyway.
The {?…} syntax means nullable. In a few situation is was used when a
parameter can be undefined. I decided to remove it everywhere and replace
it with {…|null} when appropriate, because this is much more explicit. Less
syntax to remember.
Note I'm intentionally not using the […] syntax when a parameter is followed
by non-optional parameters. Actually skipping a parameter in such a situation
would mess the parameter order up. Having optional parameters not at the end
is sometimes used as a feature in JavaScript code, but not in this codebase,
as far as I can see.
