In some places, the arrow function seems more natural. This patch
approximates the following with manual amendments:

jdlrobson f5f21a8d09 RESTBase url is configurable
Allow developers to use different endpoints for summaries
= developer happiness

This is useful for the following use cases:
* A developer wants to test against a production endpoint via
CORS
* A developer has setup an API where REST is hosted elsewhere
e.g. http://localhost:6927/en.wikipedia.org/v1/
* A user wants to create their own REST summary compatible
endpoint
* A wiki e.g. wikidata wants to use a different endpoint which is compatible
with the summary endpoint.

We are unlikely to use it ourselves on Wikimedia wikis (the
default should suffice) but this will be a powerful tool for

When not configured this will continue to work as per normal

jdlrobson ca440dfbed Remove client side formatters in Popups code base for MW API.
Stripping parentheticals were designed specifically for working around
issues with content inside wikimedia wikis and error prone.

This problem for wikimedia wikis is solved by the mobile content
service.

Given we have no intentions to use the MediaWiki API for summaries.
They are not necessarily useful to third parties and it makes little
sense to maintain them (a third party can configure their own API or
use their own REST endpoint if they really do need them).

Stephen Niedzielski e406d4556f Fix: don't assume thumbnail URLs contain pixel size
Don't assume that thumbnail URLs contain a dimension delimiter of "px-".
Previously, thumbnail URLs always contained the width. e.g.:

  https://upload.wikimedia.org/wikipedia/commons/a/aa/100px-Red_Giant_Earth_warm.jpg

However, thumbnail URLs that actually point to the original are not
sizable:

  https://upload.wikimedia.org/wikipedia/commons/a/aa/Red_Giant_Earth_warm.jpg

These are provided, for example, when the thumbnail size requested is
larger than the original. There was code designed to handle this
scenario but it only applies when RESTBase and page preview thumbnail
sizes happen to be in sync. In other words, if RESTBase requests a large
thumbnail on behalf of page previews, and page previews only requested a
small thumbnail, the original may be unexpectedly provided. A
conditional is introduced in this patch to verify that "px-" is actually
detected. If it is not present, the original is used.

jdlrobson a702c0f499 Capture page view-like interactions
* New action added PREVIEW_SEEN
* The action will be used to signal that a page view needs
to be recorded.
* PREVIEW_SEEN is a delayed action which is triggered
as a side-effect of the previewShow action. It is only dispatched
if the user is still previewing the same card and the page
related to the card has preview type `page`
* The pageview changelistener is added when
$wgPopupsVirtualPageViews is set to true.
* The page view changelistener listens for page views and logs
them using EventLogging when needed using
https://meta.wikimedia.org/wiki/Schema:VirtualPageView

Note:
* Currently if a user has enabled the DNT header, the
event will not be logged. There is ongoing discussion on the
ticket and fixing this will be addressed separately.
* Only title and referrer are logged in the initial version.
The task demands that "namespace" is logged but this information
is not provided by the summary endpoints we use so will need
to be added later (if indeed needed) either via a change to that
endpoint of by using JavaScript to parse the URL.

joakin 1fff0d2ea7 Improve & fix action and integration tests
This change fixes some issues with assertions not running, removes
unnecessary promise dances, and improves legibility and some code
patterns in the action and integration node tests mainly.

Detailed changes:

* actions.js
  * Fully migrate out of jQuery 1 promises (no done/fail)
  * Fix linkDwell action not returning the fetch action promise

* actions.test.js
  * Simplify setupWait for the tests
    * It always autoresolves immediately the wait call to ensure speedy tests
    * No waitDeferreds or waitPromises array coordination, rely on action
      returned promises instead
  * Get rid of that = this in favor of arrow functions
  * Rename generic "p" promises to meaningful names
  * Add assert.expect for more solid tests (so that we don't skip assertions in
    the future if we change them)
  * Fix some assertions that weren't being run because of the incorrect promise
    being returned (p.then, and then just returning p)
  * Get rid of $.when stubbing in favor of waiting for the promise returned from
    the action
    * Get rid of hacky setTimeout(..., 0) to run assertions after the promises

* integration.test.js
  * Get rid of wait(0) calls to hack around asynchronous actions
    * Use the action returned promises instead of the waitPromises/Deferreds
  * Remove unused "el" parameter being passed to this.abandon in several tests
  * Remove unnecessary test helper this.abandonPreview (it was the same as
    this.abandon)
  * Clarify a bit the last and more complex test with some comments and variable
    name changes
  * Get rid of that=this in favor of arrow functions

* container.test.js
  * Get rid of that=this in favor of arrow functions

* previewBehavior.test.js
  * Get rid of that=this in favor of arrow functions
  * Get rid of $.each in favor of .forEach

Stephen Niedzielski 9114981380 Update: show placeholder preview for more failures
Functional changes

- Show the default / error preview for all extract request failures
  except those due to network circumstances (such as CORS) or no
  connectivity (offline). Previously, the error preview was displayed
  only for missing pages.

- FETCH_COMPLETE was previously only dispatched after FETCH_END. Now
  it's also dispatched after FETCH_FAILED. The additional "fetch
  complete" is not expected to impact logging. The states of success
  are: START, END, COMPLETE. The new failure states are consistent with
  success: START, FAILED, COMPLETE.

Testing

Errors may be stimulated in a number of ways including:

- Timeout: add a timeout field to RESTBaseGateway /
  MediaWikiGateway.fetch().

  http://api.jquery.com/jquery.ajax/

- Bad request: change MediaWikiGateway.fetch's action field to
  `Math.random() > 0.5 ? 'query' : 'fail'` and RESTBaseGateway.fetch's
  url field to
  `RESTBASE_ENDPOINT + ( Math.random() > 0.5 ? encodeURIComponent( title ) : '%%%' )`.

- Desired Gateway can be configured in Gateway#createGateway().

- Note: T184534 describes a circumstance where cached previews may not
  appear when offline. Disable browser caching to avoid confusion.

Stephen Niedzielski 8ca0cf2088 Fix: preview page URL for 404 RESTBase responses
Functional changes:

- Require page URL when constructing a PreviewModel null object. These
  models have valid titles and are used to display a preview when an
  extract is unobtainable. When presented with an empty URL, their
  linkage incorrectly pointed to the browser's current URL. Additional
  tests were added to verify the fix.

- Check missing title in addition to falsy response in RESTBase gateway
  and update the test assertion to check title. It isn't clear if this
  can happen in the wild.

- Forbid state mutation in the conclusion of
  MediaWikiGateway.getPageSummary() with a call to Deferred.promise().
  This is consistent with the rest of repo including RESTBaseGateway.

  http://api.jquery.com/deferred.promise/

Nonfunctional changes:

- Collapse two RESTBase gateway 404 tests into one as the scenarios and
  expectations were very similar.

- Add failure HTTP status to 'MediaWiki API gateway handles API failure'
  test stub HTTP response for consistency with other cases.

- Add nullity expectations to JSDocs touched and fix a couple typos
  throughout.

- Make the gateway tests a little more consistent by collapsing Deferred
  variable usage where appropriate.

This change is necessary to the completion of T183151 which uses the
PreviewModel null objects for additional error cases.

joakin e865409593 Hygiene: Don't rely on .fail, use Promises/A+
Instead of using the non-standard old Promise implementation by relying
on .fail, migrate it to .catch.

In this specific case, where we were chaining promises with $.when, the
semantics from going from fail to catch actually change. .fail keeps the
promise in a rejected state, while .catch will change it to resolved
unless another error is thrown.

As such, when changing it to .catch, the catched error will be re-thrown
to keep the promise in a rejected state, so that $.when.then is not
executed.

Additional changes:
* Make actions.js#fetch return its promise for ease of testing.
* Test FETCH_FAILED, which was fully untested.

jdlrobson e4e9bb3bd6 Popups A/B test infrastructure
Introduce PopupsAnonsExperimentalGroupSize config variable. This defines
a population size who will be subject to experimentation. If the group
size is undefined or 0 (default) and PopupsBetaFeature is false
(default value) Popups will be enabled for everyone. If it is any other
value, half that group will see page previews.

Drop the config variable PopupsSchemaSamplingRate - we will now only
EventLog when an experiment is occuring. This means we can simplify the
MWEventLogger class as shouldLog will always be truthy. Given server
side eventlogging is only used for preference changes
traffic should be low and not need sampling.

Introduce getUserBucket which determines whether a user is in a bucket
on, off or control based on the value of
PopupsAnonsExperimentalGroupSize. Add tests showing how these
buckets are calculated.

Caution:
A kill switch wgPopupsEventLogging is provided for safety.
It defaults to false. Before merging, please check if any config changes
are necessary.

joakin e6081106f1 Use EcmaScript modules instead of common.js modules
Why: Because they are the approved standard by TC39 and Ecma for
JavaScript modules.

Changes:
  * Wrap mw-node-qunit in run.js to register babel to transpile modules
    for node v6
  * Change all sources in src/ to use ES modules
    * Change constants.js to be able to run without
      jQuery.bracketedDevicePixelRatio given ES modules are hoisted to
      the top by spec so we can't patch globals before importing it
  * Change all tests in tests/node-qunit/ to use ES modules
  * Drop usage of mock-require given ES modules are easy to stub with
    sinon

Additional changes:
  * Rename tests/node-qunit/renderer.js to renderer.test.js to follow
    the convention of all the other files
  * Make npm run test:node run only .test.js test files so that it
    doesn't run the stubs.js or run.js file.

joakin 31fa60d32c Hygiene: Move ui renderer.js to ui/ folder
Seems appropiate to group the UI portions of the source under a ui
folder.

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.

Piotr Miazga 426356e822 Remove duplicate events filtering
We had instrumentation for over 4 weeks and duplicate events rate
was very low. We want to keep stats so we check the duplicate events
rate but there is no need to filter those.

Piotr Miazga a82e54bf2d Override eventLogging to enabled when debug flag is on
In order to debug the EventLogging instrumentation in production
environments, we want to be able to bucket ourselves at will.
When the debug flag (?debug=true) is passed send all events
for given page view.
