joakin 2516299bd2 Hygiene: Lint JS files on tests/node-qunit too
For consistency.

joakin c9d325d01e Tests: Migrate processLinks.test.js to node-qunit
Tests are basically unchanged, except for some stubs on beforeEach.

Supporting changes:
* Bring stubs from the mediawiki library for mw.Uri,
  mw.Title.newFromText and mw.RegExp into stubs.js
* Remove hook onResourceLoaderTestModules given there are no resource
  loader test modules after migrating processLinks.test.js

Why bring stubs from real source? This is not optimal. It could be the
case that the stubs would need to be updated at some point in the
future. That's why in the comment of each stub, it is specified where it
came from, and what was changed to make it work. It is not optimal but
it should help with a future update if necessary.

Also checked the history of the stubs and these three stubs are very
stable with a small commits per year, usually adding some extra
functionality (not breaking changes) (the rest of the commits are
docs/format stuff), so the core behavior that we rely on here shouldn't
change in a fundamental way. See the github links:

* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Uri.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Title.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.RegExp.js

Right now this stubs allow us to bring the test to run in isolation in
node.

The initial plan was to do change the test to be less test-case oriented
with dependencies on mediawiki.*.js and not to bring fake "real" stubs,
but after looking into it, given that:
1. the test cases in the test seem pretty informative showing the kind
   of links that popups accepts
2. the stubs are acceptably easy to bring in, and are pretty stable
I decided to go with this approach initially to finish the migration
without changing the meaning of the tests.

If we want to remove the stubs and morph the test to verify stub calls
and move the test cases to documentation on the source, I'll tackle that
on a future commit.

Sam Smith 7f91068ecf Don't show preview if user has abandoned link
If the user dwells on a link for long enough, then the gateway makes a
request, which is allowed to complete regardless of whether or not the
response is required.

If the user abandons the link but the request completes before the
abandon completes - currently, ABANDON_END_DELAY is 300 ms - then the
preview will be rendered temporarily.

Fix this by not rendering the preview if the user has started to abandon
the link.

Sam Smith 2c171d7f25 reducers: Don't destroy interaction on LINK_CLICK
I09d8776 introduced a bug in the eventLogging reducer where reducing
LINK_CLICK would remove any accumulated interaction state but not close
the interaction.

Update the associated tests so that they correctly test the reduction of
this action.

Sam Smith 56aeeccb0d reducers: Make LINK_CLICK finalize but not close
... the interaction.

Following on from Iccba3c4c, LINK_CLICK shouldn't be considered the end
of an interaction because the link or preview can still be abandoned by
the user. Unlike ABANDON_END and LINK_DWELL, therefore, LINK_CLICK
musn't destroy the interaction but indicate that no more events should
be enqueued for the interaction.

More concretely, if the user has clicked the link or the preview, then
a "dwelledButAbandoned" or "dismissed" event shouldn't be logged.

Changes:
* Distinguish between "finalizing" and "closing" an interaction, where
  the latter is the current behavior of ABANDON_END, LINK_DWELL, and
  LINK_CLICK, in the eventLogging reducer and associated tests.
* If the interaction is finalized, then either the "dwelledButAbandoned"
  or "dismissed" events shouldn't be logged.

Like ABANDON_END, the LINK_CLICK should be considered the end of the
interaction in the context of the EventLogging instrumentation, i.e. no
events should be logged after the user clicks the preview or the link.

Sam Smith 76b8c18ca5 reducers: Make PREVIEW_SHOW require a token
Like the FETCH_COMPLETE and ABANDON_END actions, the PREVIEW_SHOW action
was delayed but not conditionally reduced. As ABANDON_END is delayed,
there's a potential for a race and if ABANDON_END is reduced before
PREVIEW_SHOW, then there's no interaction to reduce the action into,
which causes an error, e.g. T159490#3165276 and T162373. Making
PREVIEW_SHOW require a token stops the error occurring in this scenario.

An alternative would be to clear the timeout created in
ext.popups.Preview#show in #hide. However, this would be inconsistent
with actions#fetch and actions#abandon.

Sam Smith 1e199b67f0 actions: Simplify delaying FETCH_COMPLETE
Require that two promises are resolved (or one is rejected) before the
FETCH_COMPLETE action is dispatched. The first promise represents the
gateway request and the second represents an arbitrarily long delay. If
the first resolves before the second, then there'll be a delay until the
second resolves; whereas if the first rejects, then there's no delay.

Mixing in the delay was introduced in If3f1a06f so that the total RTT

dispatched when the gateway request ends and not when the preview model
is resolved, this additional information (state) is redundant.

Sam Smith 8b311aa159 Hygiene: FETCH_END -> FETCH_COMPLETE
Ideally, the preview model is resolved after 500 ms, regardless of
whether the internal gateway takes 100 or 300 ms. Given this, there's an
important distinction to be made between the "fetch" ending and it
completing and their associated actions.

Changes:
* Dispatch the FETCH_COMPLETE action when the preview model is resolved.
* Update the reducers accordingly.

If the user has disabled PP via the settings dialog or they aren't in

Because this behavior has to respond to the user enabling/disabling PP
within the same page session, change the linkTitle change listener

Baha 9a94300858 Log events to statsv for monitoring PagePreviews performance
For logging to work:
1. $wgWMEStatsdBaseUri needs to point to a valid statsv endpoint,
   e.g. 'https://en.wikipedia.org/beacon/statsv'.
2. $wgPopupsStatsvSamplingRate needs to be set. Note that the codebase
   already contains the EventLogging functionality, which is configured
   separately. Separately configuring different logging mechanisms
   allows us to avoid sampling mistakes that may arise while choosing
   one or the other. For example, let's say we want to use EventLogging for
   10% of users and statsv for 5%. We'd sample all users into two
   buckets: 50/50. And then we'd have to set the sampling rates as
   20% and 10% respectively, only because of the bucketing above. To avoid
   this kind of complications, separate sampling rates are used for each
   logging mechanism. This, of course, may result in situations where a
   session is logged via both EventLogging and statsv.
3. The WikimediaEvents extension needs to be installed. The extension
   adds the `ext.wikimediaEvents` module to the output page. The
   logging functionality is delegated to this module.

Notable changes:
* The FETCH_START and FETCH_END actions are converted to a timed action.
* The experiments stub used in tests has been extracted to the stubs
  file.

... thumbnails.

A good example of the difference in behaviour of the PageImages API is
here <T156800#3087507>. The API defers to File#transform, which scales
the largest dimension of an image, not always the width, e.g. if an
image is 1000px x 2000px and the request is for a thumbnail "of 1800px",
then the thumbnail will be 900px x 1800px.

Moreover, if the image happens to have the exact dimensions that we're

Sam Smith 720cfbdcd7 restbase: Use thumbnail when generating thumbnail
Rather than manipulating the URL of the original image to get the URL of
the appropriately sized thumbnail, manipulate the URL of the thumbnail
image.

While we could manipulate either the thumbnail or original image URL,
there are subtle differences between the two, so manipulating the latter
makes the generateThumbnailData function as simple as possible, e.g. we
don't have to splice in "/thumb" after "/commons".

Also, ensure that the thumbnail's dimensions are scaled appropriately.

* The other anonymous users are bucketed. By default 90% of these
  users see the feature, the other 10% don't. These numbers can be
  controlled by the config variable `wgPopupsAnonsEnabledSamplingRate`.

Sam Smith f54f92402c storage: Fix UserSettings#hasIsEnabled
mw.storage#get doesn't take a default value to return if the underlying
storage is disabled or the key is missing. In the former case it'll
return false and in the latter it'll return null, i.e. in neither case
will it return undefined.

joakin 82e315b124 Tests: Migrate {integration,actions}.test.js to node qunit
Because of the globals mw.popups.wait usage and mocking in both actions
and integration, they need to be migrated in a single step, fixing them
both to require wait.js and mock using mock-require instead of the
global variable.

Additional changes:
* Fix FIXMEs about actions.js using the global mw.popups.wait instead of
  the require one.
* Fix the unit tests to use require mocking for wait.js instead of
  global variable mocking in both integration and actions tests
* Change tests that use deferreds and promises to be async qunit tests
  (Deferreds are asynchronous with jQuery in node, apparently they
  weren't in the browser)
* Change integration.test.js to use require on Redux and ReduxThunk

Sam Smith 938a4b85d4 Hygiene: Remove checkin instrumentation
The "checkin" part of the Popups schema was superseded by the
ReadingDepth schema, the implementation of which is tracked by T155639.

As well as removing all checkin-related code, update the Popups schema
to the latest version - the version that doesn't have the checkin
property.
