Adam Wight 07aa0f3ae9 Don't record Popups actions on non-content pages
We found that Popups was overcounted approximately 2.5x relative to Cite.
This patch attempts to nearly match the circumstances under which Cite
(and its tracking) is loaded.

Adam Wight 0c1e628edb Ensure that pageviews are recorded at most once
The Popups pageviews were suspiciously high, about 2.5x higher than
Cite counts which should have reported the same number.  This patch
attempts to deduplicate pageview events.

Thiemo Kreuz 065a8e9631 Fix action reducer forgetting *all* duplicate dwell actions
I was able to track the issue down to the changes made in this patch:
https://gerrit.wikimedia.org/r/331563

This patch is mostly a simplification of ce8a2d4
(I9a73b3086fc8fb0edd897a347b5497d5362e20ef):

- Don't make wait#wait() abortable. This adds complexity and isn't
  needed since the token is rechecked in the .then() of
  actions#linkDwell(). The request is permitted to continue and fetch if
  that token still matches and is never issued otherwise.

  Once a request has been issued, that request is still abortable.
  However, note that calling XHR.abort() is just a request to abort and
  may not be granted. Whether or not XHR.catch() is invoked is what
  dispatches the FETCH_ABORTED action (or doesn't if the request to
  abort was denied).

- Remove the abort tests for wait#wait() since the functionality is no
  longer provided.

- Pass the preview token in the FETCH_ABORTED action and reduce
  FETCH_ABORTED the same way as ABANDON_COMPLETE in reducers/preview.

The follow-up patch, I3597b8025f7a12db0cf5d83cce5a77abace9bae3, adds
integration tests for the specific bug fix. Note that these Selenium
tests are incompatible with the content proxy, so it is probably best to
simply unset $wgPopupsRestGatewayEndpoint and $wgPopupsGateway and allow
the defaults to be used. Also note that the tests are incompatible with
recent versions of Node.js (so use NVM) and emit many deprecation
warnings (so set deprecationWarnings to false in
tests/selenium/wdio.conf.js) An example run of the tests looks something
like:

  chromedriver --url-base=wd/hub --port=4444 &
  # If any changes are made locally, also run `npm -s start &`.
  MW_SERVER=http://localhost:8181 \
  MEDIAWIKI_USER=foo \
  MEDIAWIKI_PASSWORD=bar \
  DISPLAY= \
  npm -s run selenium-test

Live testing may be performed as well. Remember that RESTBase requests
are incompatible with MobileFrontend's content proxy hack so ensure to
comment it out if $wgPopupsGateway is configured for RESTBase (see
T218159).

1. Open the DevTools network tab.
2. Disable the browser cache. Chromium, at least, won't abort requests
   coming form the cache.
3. Hover back and forth quickly over a preview. In Chromium, canceled
   requests are labeled and appear red. This is a good scenario to test.
   With the patch, a preview should always be shown when ultimately
   resting on a link. Without the patch, it is possible to rest upon the
   link with no preview showing. This may require several attempts.

Thiemo Kreuz 59a5e4e981 Fix fade-out gradient not disappearing when page is zoomed
We did a strict === comparison before. This works fine when the page
zoom is either 100% or 200%. Other zoom factors produce fractional
numbers. Comparing them with === is doomed to fail because these numbers
are IEEE representations, not necessarily being identical in situations
where you would expect them to be identical.

This applies two fixes: Change the comparison to a >=, and always ignore
1 extra pixel. If we are so close to the bottom, the gradient is not
helpful any more.

Thiemo Kreuz ac65bd3082 referencePreview: No event bubbling on inner child elements
This is relevant in case the HTML looks like this:
<… class="reference"><a><span>[</span>2<span>]</span></a></…>
The additional <span> cause many additional mouseover and mouseout
events. The code already tries to filter these duplicate events that
are all triggered on the same link, but gets confused, especially when
the multiple chains of events overlap each other in unexpected ways.
It's a timing issue. This change does not fix the fundamental issue,
but does make it much less painfull.

This patch also removes the > from the selector. This is in case the
HTML looks like this:
<… class="reference"><span><a>[2]</a></span></…>
The additional inner <span> would prevent any reference preview from
being shown.

WMDE-Fisch 1879a4d59e Show referencePreviews on click
Introducing the REFERENCE_CLICK action that will fetch and show the
preview for the clicked reference right away without any delay.

The main goal of the new chain of events introduced with the reference
click is showing the reference preview right away. The actions triggered
by the dwelling include delays in multiple parts of the process.

If there's a dwell action-chain in progress when the click action is
executed, the related promise ( that might still include steps with
delays ) and the reference preview is retrieved and shown right away
re-using the token. 

In the case where there's no dwell action running ( e.g. when the click
was triggered via touch ) we create a new token and start from scratch.

In either case we want to avoid, that multiple clicks trigger multiple
actions and abort early when there's already a click action in progress.

I actually tried to bring the animation for the "bottom" property back.
When finished, I realized this animation is done on *top* of the

need to keep animating the opacity.

This patch here contains a bit of refactoring that was left after I
went back animating the opacity.

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.

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.

Thiemo Kreuz 9438210889 Teach the title parser to always accept self-links
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).

Thiemo Kreuz 90acf2a778 Fix pointer mask and CSS offsets for flipped popups
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.

Thiemo Kreuz 33cb635e53 Improve documentation of the previewType constants
As well as:
* Simplify the selectGatewayType() function a bit. Or was this
  intentional?
* Remove a TODO we don't need any more, at least not in this file.

Thiemo Kreuz 5bc4ed8f9f Exclude links in popups to trigger other popups
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.

Thiemo Kreuz 0686f40069 Move possibly expensive title parser construction down
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.

Thiemo Kreuz d45c6cd273 Move thumbnail rendering code into pagePreview renderer
This is now possible since the render functions return jQuery objects.
All this code is exclusively used in the pagePreview.js file, and
doesn't need to make the already very big renderer.js file even
bigger.

Note the tests for all renderers have always been collected in a
single file. That's why the test case does not move.
