Thiemo Kreuz 5d2c5aeaa1 Remove a small piece of unused code from reference.js
Turns out this was only in place because the test was
(intentionally) incomplete. But it's dead code in
production. Let's get rid of it.

Thiemo Kreuz 513899d808 Much more relaxed reference type detection
* When there are multiple <cite> elements, the first that contains a
  known class is used. We assume the earlier one must be the relevant
  one.
* When there are multiple known classes in e.g. <cite class="web news">,
  the last one is used. This follows how CSS works.
* There is extra validation if the corresponding message exists, just
  to be sure. This is cheap.

Thiemo Kreuz 8fbcf6f962 Add missing TextExtracts parameter sectionformat=plain
It turns out the TextExtracts extension is build in a way so
that the parameter plaintext=1 alone is not enough. It does
not really mean "please return plain text" but "please don't
return HTML". It can still return one of three formats:
* Wikitext.
* An intermediate parser format where headlines are not
  `== this ==` but `��2��this`.
* Actual flat plain text.

The default is wikitext. That's why we see `== wikitext
syntax ==` in certain edge-case situations. Forcing it to
"plain" fixes this.

Thiemo Kreuz 7d2de31fd9 Don't show preview popups with no visible content
I played around with a lot of options, and settled with:
* When there is nothing but text, but the text is all
  whitespace, don't show it.
* Make sure an <img> with no text is still shown. This is done
  by checking for child elements.

A possible future enhancement could be to check the visible
width of the element as well. Unfortunately this fails in
tests. Everything is 0 in tests.

Thiemo Kreuz 8305eb8634 Minimize createStubTitle() helper method
Pretty much all usages of this function do *not* use the second
parameter to pass a page name prefixed with a namespace, but pass the
page name only.

This patch here removes the redundancy. The namespace prefix is now a
generated one, saying "Namespace <number>:…". It turns out no test
relies on this so far.

WMDE-Fisch 0d2d6d4c9b Move getPreviewType form gateway to model
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
as preparation for that patch.

Thiemo Kreuz d1c0613186 Fix regression showing page previews on ^ jump mark links
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.

two CSS class names, "mw-reference-text" and "reference-text". So far
our scraping gateway only implemented one.

This patch also extracts a piece of code to a named function. This makes
it much easier to read, I feel.

Thiemo Kreuz 90d7edb17c Streamline jQuery object creation
As discussed, the $( '<a>', { id: 'foo' } ) syntax is bogus because
plugins are able to *change* it. It's not just a list of attributes,
but whenever there is a method with the same name, that method will be
called instead. This means the result of this feature is unpredictable.

This patch also streamlines a few other jQuery calls that can be
shortened.

Thiemo Kreuz 03ef969122 Show reference previews only on self-links
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.

Thiemo Kreuz 515775685c Fix a series of issues with misdetected reference elements
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.

Thiemo Kreuz 0a8f591212 Rewrite title module to preserve all link's #fragments
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]].

Thiemo Kreuz bb60d5b716 Move default "Footnote" title from gateway to renderer
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.

It also includes a test for the default fallback title.

Thiemo Kreuz 57fd85fc68 Rename getPageSummary to fetchPreviewForTitle
It's not exclusively about page summaries any more.

We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
  generic and don't describe well what the method does. As a reminder:
  It expects a Title object and returns a promise, which returns a
  PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
  return a model object.

So I went for fetchPreviewForTitle. What do you think?

Piotr Miazga 2527f931a2 Properly handle catch() when calling gateway fetch.
Previous implementation did not pass the `result` variable
to the catch() statement. Because of that every execution that
ended with exception inside fetch() statement was threated as
not a network exception and tried to present the null preview.

Changes:
 - properly handle data returned by rejected fetch promise
 - chaged the big if (result && result....) into something easier
 to read
 - pass Error object instead of 'http' string
 - Restbase can return exception, it doesn't have to handle the 404
 errors by itself, it's already taken care in the catch() logic
 - fixed unit tests to reflect new logic in restbase gateway

Stephen Niedzielski ce8a2d4c3f Update: cancel unused HTTP requests in flight
Whenever an HTTP request sequence is started, i.e. wait for the fetch
start time, issue a network request, and return the result, abort the
process if the results are known to no longer be needed. This occurs
when a user has dwelt upon one link and then abandoned it either during
the fetch start wait time or during the fetch network request itself.

This change is accomplished by preserving the pending promises in two
actions, LINK_DWELL and FETCH_START, and whenever the ABANDON_START
action is issued, it now aborts any previously pending XHR-like promise,
called a "AbortPromise" which is just a thenable with an abort() method.
There is a similar concept in Core:
ecc812f06e/resources/src/mediawiki.api/index.js.

Aborting pending requests has big implications for client and server
logging as requests are quickly canceled, especially on slower
connections. These differences can be observed on the network tab of
DevTools and the log in Redux DevTools.

Consider, for instance, the scenario of dwelling upon and quickly
abandoning a single link prior to this patch:

  BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_END STATSV_LOGGED ABANDON_END EVENT_LOGGED FETCH_COMPLETE

And after this patch when the fetch timer is canceled (prior to an
actual network request):

  BOOT EVENT_LOGGED LINK_DWELL ABANDON_START ABANDON_END EVENT_LOGGED

In the above sequence, FETCH_* and STATSV_LOGGED actions never occur.

And after this patch when the network request itself is canceled:

  BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_FAILED STATSV_LOGGED FETCH_COMPLETE ABANDON_END EVENT_LOGGED

FETCH_FAILED occurs intentionally, STATSV_LOGGED and FETCH_COMPLETE
still happen even though the fetch didn't complete successfully, and
FETCH_END doesn't.

Additionally, since less data is transmitted, it's possible that the
timing and success rate of logging will improve on low bandwidth
connections.

Also, this patch tries to revise the JSDocs where possible to support
type checking and fix a call to the missing assert.fail() function in
changeListener.test.js.

Stephen Niedzielski ece4670710 Hygiene: use arrow for anonymous functions
In some places, the arrow function seems more natural. This patch
approximates the following with manual amendments:

  find \
    -not \( \( -name node_modules -o -name .git -o -name vendor -o -name doc -o -name resources \) -prune \) \
    -iname \*.js|
  xargs -rd\\n sed -ri 's%function\s*(\([^)]*\))%\1 =>%g'

Files to focus on were identified with:

  rg -slg\!/resources/dist/ -g\!/i18n/ -g\!/doc/ 'this|self|arguments|bind|call|apply|new'|
  xargs -rd\\n git difftool -y

jdlrobson f5f21a8d09 RESTBase url is configurable
Allow developers to use different endpoints for summaries
= developer happiness

This is useful for the following use cases:
* A developer wants to test against a production endpoint via
CORS
* A developer has setup an API where REST is hosted elsewhere
e.g. http://localhost:6927/en.wikipedia.org/v1/
* A user wants to create their own REST summary compatible
endpoint
* A wiki e.g. wikidata wants to use a different endpoint which is compatible
with the summary endpoint.

We are unlikely to use it ourselves on Wikimedia wikis (the
default should suffice) but this will be a powerful tool for

When not configured this will continue to work as per normal

jdlrobson ca440dfbed Remove client side formatters in Popups code base for MW API.
Stripping parentheticals were designed specifically for working around
issues with content inside wikimedia wikis and error prone.

This problem for wikimedia wikis is solved by the mobile content
service.

Given we have no intentions to use the MediaWiki API for summaries.
They are not necessarily useful to third parties and it makes little
sense to maintain them (a third party can configure their own API or
use their own REST endpoint if they really do need them).

Stephen Niedzielski e406d4556f Fix: don't assume thumbnail URLs contain pixel size
Don't assume that thumbnail URLs contain a dimension delimiter of "px-".
Previously, thumbnail URLs always contained the width. e.g.:

  https://upload.wikimedia.org/wikipedia/commons/a/aa/100px-Red_Giant_Earth_warm.jpg

However, thumbnail URLs that actually point to the original are not
sizable:

  https://upload.wikimedia.org/wikipedia/commons/a/aa/Red_Giant_Earth_warm.jpg

These are provided, for example, when the thumbnail size requested is
larger than the original. There was code designed to handle this
scenario but it only applies when RESTBase and page preview thumbnail
sizes happen to be in sync. In other words, if RESTBase requests a large
thumbnail on behalf of page previews, and page previews only requested a
small thumbnail, the original may be unexpectedly provided. A
conditional is introduced in this patch to verify that "px-" is actually
detected. If it is not present, the original is used.
