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.

Enforce it with eslint.

Ignore:
* Comment lines with eslint disable directives
* QUnit test lines as they contain long subjects (QUnit.* (only, test,
  module, skip, etc)
* Strings, since long strings are used extensively in tests
  * Ignore template literals for similar reasons
* Regex literals as they may be too long, but can't be easily
  split in several lines
* Long urls

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.

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 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 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 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.

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.

Sam Smith 83e32c255d reducers: Make LINK_CLICK finalize interaction

Like ABANDON_END, the LINK_CLICK should be considered the end of the

events should be logged after the user clicks the preview or the link.

See T159490#3172692 for additional context.

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 6042000eb1 actions: Don't mix delay into FETCH_COMPLETE
Mixing in the delay was introduced in If3f1a06f so that the total RTT
for an API request could be calculated. Now that the FETCH_END action is
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.

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.
