Sam Smith cf0ea9db7b actions: Mix title and namespaceID into LINK_DWELL
This fixes a bug in I8a63d82, where the pageTitleHover and
namespaceIdHover properties of EventLogging events weren't being set.

Sam Smith 35bf613964 eventLogging: Add missing *Hover properties
Action changes:
* Include the namespace ID in LINK_DWELL.

Reducer changes:
* Add the createEvent helper, which adds the pageTitleHover and
  namespaceIdHover properties in the event.
* Create "dismissed", "dwelledButAbandoned", and "opened" events using
  the createEvent helper.

Additional changes:
* Store the target page's associated mw.Title using jQuery.
* Update the eventLogging reducer's test cases so that all LINK_DWELL
  representations include title and namespaceID attributes.
* Create the createStubTitle factory function, which returns a minimal
  usable mw.Title stub, and use it in the actions and integration test
  cases.

Sam Smith c44fddf8cd eventLogging: Discard events with duplicate tokens
I6a38a261 made the eventLogging change listener count and discard
duplicate events and count duplicate tokens.

While we isolate the issue(s) that lead to duplication (reuse, likely)
of tokens, make the eventLogging change listener discard events with
duplicate tokens as well.

Baha d6424cb59d QA: Test renderer#show
Binding the behavior has been left out as it requires some refactoring.
Ideally, that functionality should be tested via integration tests, which
is already done.

Sam Smith 35cfc38b0b eventLogging: Add missing perceivedWait property
Per the Popups schema [0], the "dismissed" action expects the
perceivedWait property to be set.

Happily, the time until the preview was shown is already recorded and
used to determine whether or not to create a "dismissed" or
"dwelledButAbandoned" event.

Reducer changes:
* When creating the "dismissed" event, set the perceivedWait property to
  the already accumulated timeToPreviewShow.

browser. Tidy up references to QUnit inside of the codebase and tooling.

  of sending beacons while running the QUnit test suite as it's no

The tests were removed in Iae0a78d0b8a13353de70794b67387f2c3bab44c6.
The ultimate goal is to refactor the renderer code and make it
testable, but before doing so we need to add tests to cover the existing
code. This will give us confidence that we won’t accidentally break
anything when we refactor.

Some of the tests have been removed as the functionality covered by
those were moved to model.js in I20f29657fcf94101a71ed13c0920508db71292ce.

Sam Smith 79f3b318d0 Track and discard duplicate enqueued events
The eventLogging change listener is responsible for ensuring that the
internal state of Page Previews matches its external state (that
perceived by the user and UA). It does this by logging events with
ext.eventLog.Schema#log. This makes it the perfect place to track and
discard duplicate events enqueued by the Page Previews codebase observed
in T161769.

Make the change listener track events that it's logged by storing hashes
of the dynamic parts of them in memory. If the eventLogging change
listener sees the same event more than once, then it discards it and
increments a counter in StatsD.

This behaviour should be enabled for a matter of days as we should see
whether the duplicate events are being enqueued by the Page Previews
codebase immediately.

Sam Smith 3d0899c0a0 Remove isLoggingEnabled with Null Object pattern
The statsv change listener depended on both the analytics tracking
function and whether it should log metrics to StatsD. We can simplify
the behaviour of the change listener by passing in a function which
doesn't log metrics to StatsD if such logging is disabled.

The change listener is now more isolated from other components.
Moreover, sharing the analytics tracking function with other components
is simpler as there's no repeated code.

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 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.

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.

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.

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.

Sam Smith da7325a169 changeListeners: Conditionally empty link titles
If the user has disabled PP via the settings dialog or they aren't in
the experimental condition, then link titles shouldn't be emptied.

Because this behavior has to respond to the user enabling/disabling PP
within the same page session, change the linkTitle change listener
rather than conditionally registering it.

Sam Smith ae9733b2f0 eventLogging: Log abandon event when user dwells
If the user abandons link A (or preview A) and immediately dwells on
link B, then log a "dismissed" or "dwelledButAbandoned" event.

In this context, "immediately" means before the ABANDON_END action is
dispatched, which, currently, is 300 ms after the ABANDON_START action
is dispatched.

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.

Sam Smith 568b7a09a1 rest: Always scale thumbnail's largest dimension
... 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.

Sam Smith d4caff9774 rest: Don't scale unscalable thumbnails
If the image isn't an SVG then it shouldn't be scaled past its original
dimensions. Handle the case where the requested thumbnail can't be
generated on the server as the original is too small ( < 320px,
currently [0]) in the same way.

Moreover, if the image happens to have the exact dimensions that we're
requesting (300px or 600px wide, currently [1]), then use the original
image to avoid unnecessary work/pressure on caches.

Supporting changes:
* Update the SVG_RESTBASE_RESPONSE fixture to use the extension returned
  by RESTBase (and the PageImages extension) for the thumbnail:
  .svg.png.

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 render change listener is hard coupled to the renderer file, so in

In order to do one thing per commit, we're mocking the require call
here to get the migration done, but added a FIXME to use dependency
injection instead in a future change.
