Adam Wight 877c2f3e12 Clicking on a reference should behave normally
We no longer intercept reference clicks, now clicking on a reference
label will scroll to the reference definition in the same way as when
reference previews is disabled.

Metrics about clicking on the label are collected by the Cite
extension, are are unaffected by this change.

Thiemo Kreuz 1cf721e2a2 Handle collapsible & sortable elements in reference popups
Elements that are marked as collapsible (often tables, but can
actually be anything) are most certainly marked as such because
they are big and don't fit in a popup.

Another plugin makes tables sortable.

In both cases non-functional UI elements appear in the popup.
We decided:
* Hide collapsible elements (no matter if currently collapsed
  or not), and show a placeholder text instead.
* Remove sortable arrows.

This is a baseline patch that solves everything, except the
(i) icon is missing. This will be added in the next patch.

There are 3 types of links:
* Links with no class are links to other pages in the same wiki.
* Links with "extiw" are interlanguage as well as interwiki
  links to other known wikis (e.g. from Wikipedia to Wikidata).
* Links with "external" point to somewhere else on the web.

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.

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.

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

This patch here removes the redundancy. The namespace prefix is now a

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.

bigger.

Note the tests for all renderers have always been collected in a

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 7db6508a77 Remove unused model elements from renderer tests
I do find these very confusing and would like to remove them:

* The test setup looks like these popup types are going to use
  these properties. But they don't. They are not even trying to
  access these properties.
* There are no assertions that make sure these properties are
  *not* used. It would be possible to add something like this,
  but I honestly think this is not worth it.

We might need to reflect this in the PreviewModel documentation
in src/preview/model.js. I would like to do this in a separate

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 a8859658f5 Add missing HTML escaping to all existing page preview types
Including tests for all situations.

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.

I found two possibly relevant security reviews of this extension, T88171
and T129177, resolved in 2015 and 2016.

Instead of maintaining a list of named constants (which must be updated
every time we want to add a new test with a new message), the mock now
behaves like MediaWiki's build-in qqx dummy language code and returns
the message key in brackets. The additional benefit of using the
HTML-like <…> characters is that this will automatically test if the
messages are properly HTML escaped.

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.

Thiemo Kreuz 97a5d335d7 Replace rare {!…} and {?…} JSDoc syntax
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.

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?

Stephen Niedzielski ab7a5808ef Hygiene: update JSDoc boxed and JQuery types
Although Popups only uses JSDocs at this time which seemingly doesn't
care about casing[1], we should endeavor to use the proper return types.

This patch lowercases typing to indicate primitive / boxed type as
appropriate.[2] As a special case, function types are uppercased for
compatibility with TypeScript type checking.

Lastly, JQuery types are of type "JQuery". The global JQuery object's
identifier is "jQuery". This patch uppercases J's where appropriate.

Piotr Miazga 4684b39841 Hygiene: use actionsTest consts instead of hardcoded states
The unit tests should use defined action types instead of hardcoding
each state.

Piotr Miazga c823a0e6cb When request gets aborted it shouldn't finish with FETCH_FAILED
Whe user moves mouse away and we abort the http request we shouldn't
count that request as a FETCH_FAILED. The reasoning behind is that
FETCH_FAILED state increments the counter.PagePreviewsApiFailure.
Our StatsD graph gets polluted with lots of aborted requests and it
becomes unsuable. It doesn't show only the failed requests.

Changes:
 - introduced new state: FETCH_ABORTED
 - switch to FETCH_ABORTED when browser aborts the request

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

Instead of mixing window.mediaWiki / mediaWiki and window.jQuery /
jQuery references, always refer to globals which exist whether code is
executed in browser or headless Node.js environments.

Piotr Miazga c1d281f0dc Send the Accept-Language header when calling API
Changes:
 - added acceptLanguage as a config option passed to
 both mwApi and restbaseApi, by default code will use
 the language defined in `wgContentLanguage` config
 variable. The `wgContentLanguage` is always defined
 (see ResourceLoaderStartUpModule::getConfigSettings())
 so there is no need for checking the variable existence.

The new logic was tested both on MediaWiki API and Restbase API

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.

jdlrobson 6c17af260c Extracts can expand with narrow thumbnails
If a thumbnail is narrow, then the extract can expand to take
the available space. It does this via JavaScript taking the difference
between the normal space for a thumbnail minus the actual space needed
to display the thumbnail.

This removes unused whitespace in both the thumbnail and extract.
