Sam Smith ba3c0b7f76 Hygiene: i13n: Return false over not sampling
Previously, if the browser didn't support the Beacon API, then
instrumentation/eventLogging#isEnabled would bucket the user with a
sampling rate of 0, which is equivalent to returning false. This change
simply does the latter.

Additional changes:
* Update the documented module names of the instrumentation/eventLogging
  and statsv modules.

We had instrumentation for over 4 weeks and duplicate events rate

Sam Smith dcf8532cdf Hygiene: Group instrumentation modules
Following on from I4f653bba, since the schema and statsvInstrumentation

Sam Smith 67eb3b1dcf i13n: Log EL events with mw.track
Currently, the mw.eventLog.Schema class samples per pageview. However,
we expect that if a user is bucketed for a session, then all
EventLogging events logged during that session are in the sample.

Moreover, loading the class in the way that we did - asynchronously,
using mw.loader#using - introduced an issue where the eventLogging
change listener would subscribe in the next tick of the JavaScript VM's
event loop and miss the "pageLoaded" event being queued (see T167273).

Changes:
* Make the schema module follow the form of the statsvInstrumentation
  module, i.e. make it expose the #isEnabled method, and add the
  associated getEventLoggingTracker function.
* Update the eventLogging change listener accept the tracker returned by
  getEventLoggingTracker.
* Update/fix related JSDoc documentation.

joakin 98d9415361 Hygiene: Rename builder vars on require preview/model
preview/model is just a module/namespace object, not a builder class or
similar.

This patch changes a couple of imports to reference some of the exposed
functions of the preview/model where required.

In a shiny future, this pattern would be:

    const { createModel, createNullModel } =
      require( '../preview/model' )

joakin 010a4d91a6 Hygiene: Simplify gateways
gateway/*/rest were copies of gateway/restProvider just passing
a different provider. Docs were the same, they were untested, and
looking at them they seemed like unnecessary abstraction.

This patch removes the plain vs html structure, and separates gateways
like before, by endpoint.

There is a light utility in gateway/restFormatters.js that adapts the
call from the rest gateway to use formatters.js functions. It needs
testing, that I'll add in the next patch.

The flow for creating a gateway ends up as follows:

1. index.js calls gateway/index#createGateway( mw.config )
2. createGateway chooses based on wgPopupsGateway and invokes
  * mediawiki.js#createMediaWikiApiGateway or
  * rest.js#createRESTBaseGateway w/ restFormatters.js#parsePlainTextResponse or
  * rest.js#createRESTBaseGateway w/ restFormatters.js#parseHTMLResponse

Changes:
* Removed src/gateway/{plain,html}/rest.js
  * Extracted formatter functions to src/gateway/restFormatters.js
* src/gateway/plain/mediawiki.js -> src/gateway/mediawiki.js
         * tests/node-qunit/gateway/plain/mediawiki.test.js ->
           tests/node-qunit/gateway/mediawiki.test.js
* gateway/restProvider{,.test}.js -> gateway/rest{,.test}.js
* Change gateway/index.js#createGateway to properly call the rest
  gateways with the rest formatters

Refactor existing Restbase gateway and extract shared logic into

names are more explicity.
 * Htmlize() became formatPlainTextExtract() as it should be used
   only with plain text extracts
 * removeEllipsis() became  removeTrailingEllipsis() as it removes
   only trailing ellipsis.
 * src/gateway/index.js defines gateways by configuration name stored
   in extension.json

joakin 293d7ebe8d Clear interaction after an event for it is logged in EL
Given that interactions end up with an event logged, there shouldn't be
a reason to keep an interaction active after it's corresponding final
event has been logged. See Tbayer's state graph.

This patch removes the current interaction if an event with that token
is logged, effectively finalizing it and making it impossible for the
token to be reused from the state tree again.

Additional changes:
* Pass the logged event with the action EVENT_LOGGED so that the reducer
  can determine if it needs to do anything else.
* Since the interaction is removed, when undefined, guard against
  actions that use state.interaction freely. (Only allow BOOT,
  LINK_PREVIEW, and EVENT_LOGGED)

Sam Smith 742f341e5c Hygiene: Tidy up QUnit references
Since Ieea378c9 all QUnit tests are run in Node.js and not in the
browser. Tidy up references to QUnit inside of the codebase and tooling.

Changes:
* Don't exclude src/processLinks.js in Istanbul code coverage reports.
* Don't test for window.QUnit in createSchema. We no longer run the risk
  of sending beacons while running the QUnit test suite as it's no
  longer run in the browser.

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.

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.

As noted in T160406, the only QUnit tests that requires a running
MediaWiki instance is the test for mw.popups.processLinks. The function
itself is isolated from the rest of the codebase.

Now, as noted in T162876#3182198, during boot the
ext.eventLogging.Schema module is loaded asynchronously with
mw.loader.using. Since boot is unconditional and happens ASAP this
happens when the tests are loaded and run.

In the short term this can be avoided by not making the tests depend on
the entire codebase. The long term solution is laid out in T160406.

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.

Bartosz Dziewoński 7967ab77ee Properly create the <svg> and <image> elements for thumbnails
We have to be careful about the namespaces here, and then we don't
need the awful `.html( .html() )` hack. (I honestly have no idea
why that even worked for some browsers, it really shouldn't have.
The comment next to it is wrong.)

* Construct the 'svg:svg' element with the right namespace
* Set 'xlink:href' attribute on 'svg:image' element with the right namespace

Doing this correctly makes the thumbnails work in Opera 12, and it also
works as before in (at least) Chromium 57, Firefox 53, IE 11 and Edge.

I can't find out what version of Safari the other hack here was
supposed to apply to, but the code was wrong in both cases, and the
hack was mistakenly also applied to modern Chromium.

Sam Smith 59ea7a3162 actions: Increase API request delay to 150 ms
Step 1 of T161284. Given that the median API response time (as measured
by the client) is ~115 ms [0] and the API response is artificially
delayed so that the preview starts fading in at 500 ms, we can increase
the API request delay to 150 ms without affecting the current UX while
decreasing the number of incidental HTTP requests triggered by the user
glancing their mouse over a link to another page.

jdlrobson b01e11c1f9 Popups doesn't need to depend on EventLogging
When EventLogging is unavailable do not initialise the EL-related code
or try to send any events.

When EL is enabled for a brand new user we request an additional module
during boot causing an additional HTTP request. Page Previews continues
to boot normally regardless of whether the request fails.

This approach doesn't impact boot or first paint time. Once the module
is loaded once it should be cached locally, subject to the
ResourceLoader's policy. Moreover, the RL will not attempt to load the
module twice so this doesn't impact the performance of other modules.

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.

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.

Rather than manipulating the URL of the original image to get the URL of

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.

Until this appears in core it makes sense to package it up as
part of ext.popups resource loader module.

Version numbers from npm are pinned to exact versions to control the
upgrade path of the libraries instead of leaving it to semver on
developers machines.

joakin 557fd113c8 Hygiene: Use factory functions instead of classes
Instead of using constructor functions, use factory functions to
generate the gateway objects, because of:

* Consistency on the approach in the repository, no constructor
  functions are used, the factory function pattern prevales.
* Real private data with closures
* No use of `this`, which is dynamic and unbound in JS and a source of
  errors. In contrast, by using a factory function, the
  function/methods-of-the-object are tightly bound to the internal data.

Additional changes:
* Specify more the type of createRESTBaseGateway's parameter to improve
clarity on the intent of the parameter
  * From: @param {jQuery} api
  * To:   @param {Function} ajax function from jQuery for example

The existence of these files was causing me much confusion as I thought

If this is note the case they should be removed to make the repo easier

Changes:
* Move the ext.popups.animation.less into ext.popups since that's where
its shipped.
* Remove files which are not being used.
* Since csslint now runs on ext.popups.animation.less fix the linting
issues (previously linting was not occuring)

Note this is a breaking change in the sense that it breaks the function

and hasnt been exposed for public use I have deemed this okay.

Sam Smith 622f2af318 gateway: Don't create new object for thumbnail
As noted in the review of I71a8a84, creating a new object to represent
the thumbnail is confusing. It's also somewhat wasteful.

Since both the MediaWiki API and RESTBase both agree on using "source"
as the key for the thumbnail's URL, it's reasonable to use it in the
gateway and renderer.

Sam Smith e3ae38f966 Introduce preview model
After the gateway has made a request, it processes the page. This
processing both mangles and processes the MediaWiki API response. The
latter step contains two pieces of related business logic:

1. Deciding if a page has been modified recently.
2. Processing the extract/deciding if it's viable (see processExtract).

In order to support switching between the MediaWiki API and RESTBase and
to simplify the event logging reducer when it comes to instrumenting the
"type" of preview, extract this business logic into a model.

Sam Smith c6a502954d Vary cog click behavior
The behavior of the cog varies when:

* The user is logged in/out.
* Page Previews is enabled as a beta feature.

Since the behavior of the cog doesn't vary per-preview, it can be
determined at boot time and passed to the renderer. However, in order to
keep the renderer stateless, we pass the behavior to it when a preview
is added to the DOM.

Changes:
* Add the mw.popups.createPreviewBehavior factory function, which
  returns an object that encapsulates how a preview responds to the user
  dwelling on it, abandoning it, and clicking on the cog.
* Invoke mw.popups.createPreviewBehavior at boot time and pass it to the
  mw.popups.changeListeners.render change listener, which then passes it
  to mw.popups.Preview#show.
* Make mw.popups.Preview#show responsible for binding event handlers
  and configuring the cog based on the behavior.
