Jan Drewniak 95b880aa29 Return promises from action thunks
Returning promises from the `linkDwell` and `abandon` thunks and
removing some of the `wait` stubs in the unit test for these actions.

Also converting a fetch callback from a `.fail` to a Promise A+

joakin 807100bcca Limit line length to 80 characters
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

joakin 7169210406 Remove unnecessary .promise() call
In the mediawiki gateway fetch uses mw.Api which when calling ajax
returns a promise (not a deferred).

Thus .promise() here is unnecessary and happens to work because of
jQuery promises but it is not a standard method on JS promises so it
shouldn't be used on promises, only on deferreds.

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.

Bartosz Dziewoński b63d2262f8 Don't use ES6 Number.isNaN
Number.isNaN is a new function introduced in ECMAScript 6.
MediaWiki only requires ECMAScript 5 supports from browsers.
Notably, Opera 12 does not have Number.isNaN. Instead, use
the global isNaN function (which behaves the same except for
non-numeric inputs).

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.

Under some unknown circumstances getPreviewCountBucket() is called
with a value that is not a -1 or a natural number. When that happens
function returns 'undefined bucket' which causes eventLogging to
fail. I wasn't able to reproduce the issue, it might be specific
to browser/os. The safest way is to return 'unknown' for any other
case.

  * 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.

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.

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

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 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.

Sam Smith d55e8b9a17 Don't load entire codebase in QUnit tests
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.

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.

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.

joakin 78cb95cda2 Hygiene: Remove unnecessary IIFE and use proper requires
In index.js. Instead of using the global variable/object popups, require
things from their files so that we can remove the global variables when
we can run qunit tests with commonjs in node.

joakin ba4844cdc2 Tooling: Separate built resources from RL resources
In order to automatically verify in CI that the built assets are up to
date with the commited sources, we need to keep the built assets in
a folder separate from the RL assets.

* Rename the compiled assets folder to industry standard `dist`
