Thiemo Kreuz 0c889c4cd4 Add default OOUI reference icon to all reference popups
I tried hard to keep the CSS as small and robust as possible. The
icon will be align with the text by adding a negativ margin. With
that we also decided against using RTL and LTR specific icons that
are positioned at the edge of the canvas for now.

Thiemo Kreuz bb60d5b716 Move default "Footnote" title from gateway to renderer
I guess both is fine: either having the default in the gateway (as it
was before), or in the renderer (as this patch proposes). I, personally,
feel better with having it closer to where it is needed. This way it's
not possible to accidentially deliver a model object with an empty title.
The renderer will catch this.

At the moment we don't know exactly how we will fetch other titles (e.g.
"Book").

This change is split from I15611a4 where it was a little misplaced.

It also includes a test for the default fallback title.

Thiemo Kreuz 46cda9fa44 Add missing escaping for jQuery ID selector
Special characters that have a meaning in one of the many different input
formats jQuery accepts must be escaped.

The real-world use-case are references like <ref name=":1"> with a colon.
But it's many more characters that need escaping. See
http://api.jquery.com/category/selectors/

Note this patch misses a test. I already uploaded I9ec57e0 to fix the
currently incomplete tests. But I can't make it work. How do I create an
element in the test environment so that jQuery finds it?

I suggest to merge this and continue working on the tests later, because
this is currently one of the most annoying issues that makes all testing
unreliable.

Thiemo Kreuz 97a5d335d7 Replace rare {!…} and {?…} JSDoc syntax
This is documented at http://usejsdoc.org/tags-type.html, but not in many
other places, especially not in the JSDuck documentation.

The {!…} syntax means "can not be null". This is the default anyway.

The {?…} syntax means nullable. In a few situation is was used when a
parameter can be undefined. I decided to remove it everywhere and replace
it with {…|null} when appropriate, because this is much more explicit. Less
syntax to remember.

Note I'm intentionally not using the […] syntax when a parameter is followed
by non-optional parameters. Actually skipping a parameter in such a situation
would mess the parameter order up. Having optional parameters not at the end
is sometimes used as a feature in JavaScript code, but not in this codebase,
as far as I can see.

Thiemo Kreuz 57fd85fc68 Rename getPageSummary to fetchPreviewForTitle
It's not exclusively about page summaries any more.

We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
  generic and don't describe well what the method does. As a reminder:
  It expects a Title object and returns a promise, which returns a
  PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
  return a model object.

So I went for fetchPreviewForTitle. What do you think?

Thiemo Kreuz 170ab5422a Rename current gateway to pagePreviewGateway
This is split from the current draft patch Ie0ccb03. This is part of a
series of very small patches that prepare the code for new types of popups.

We decided to not add code for other types of popups to the existing
createGateway() function, but introduce new files and functions instead.
Renaming, for example, the existing `gateway` variable name will make it
much more obvious which of the future gateways does what.

Thiemo Kreuz aaa40b4fbe Also exclude the Cite extension's "Jump up" backlinks
This became an issue after the patch Ifa56d41 (part of T206323) removed
some hidden <span> and replaced them with title="…" tags. The CSS selector
in src/index.js get's active on all <a> elements that have a title="…"
attribute. This is now the case for all references that are used one time
and have their ↑ (or ^ on the English Wikipedia) linked.

I realized this is really only an issue for these ↑ links.

The more general issue described in T198652 still holds true, but becomes
less urgent with this bugfix.

Jan Drewniak 83a28d177f Storybook.js for Popups
Storybook.js provides a framework for
viewing and working with UI components.
https://storybook.js.org/

This patch adds the Storybook.js UI library to Popups for
the purposes of viewing multiple previews at once.
This enables viewing page previews in the following states:

- with thumbnails
- without thumbnails
- with SVG thumbnails
- with narrow thumbnails
- with white background thumbnails
- in RTL languages
- in non-latin languages
- disambiguation popups

Storybook also allows users to change the image or text
of a popup through a GUI.

This patch sets up Storybook as a "mini" repo inside
the.storybook folder with a seperate package.json file
to avoid incompatibilities with the current webpack/babel
(or even Node) versions used in the Popups repo.

Storybook requires at least Node v8.3 to run.
(an .nvmrc file with 11.3.0 has been added to the .stories dir).

To start:
`cd .storybook && npm install && npm run start`.

Stephen Niedzielski 81a2f4acb0 Hygiene: copy MobileFrontend Webpack learnings
Copy learnings from MobileFrontend's Webpack configuration. If nothing
else, the files are more consistent and easier to diff. When the change
to rename source maps is excluded, the build products are identical.

The following changes were copied:

- DRY up the output directory and source map extension as variables. For
  the latter, rename the source map from ".json" to ".map.json". Without
  renaming, the build products are unchanged.
- Reduce verbosity. Only report warnings and errors.
- Fail to build when an error occurs.
- Update ordering and add comments for easier reasoning and diffing with
  MobileFrontend.

Nicholas Ray 63031429b8 Upgrade redux / redux-thunk
redux       | 3.6.0 | 4.0.1
redux-thunk | 2.2.0 | 2.3.0

Upgrading these two dependencies caused the build size to increase from
from 12.2 KB to 12.4 KB (gzip) and so the bundlesize was adjusted
accordingly in our package.json.

Additionally, our linters flagged two rules that were then turned off in
.eslintrc.es5.json.

Looks like the changes in Redux were mostly cosmetic with much work
dedicated to typescript definitiions and dropping support of private
imports [1].

The changes to redux-thunk only involved changing typescript typings and
should not affect us. [2]

The upgrade was tested locally and did not appear to break anything.

Nicholas Ray 0c1a65f39d Upgrade webpack / webpack-cli
webpack     | 4.1.1  | 4.27.1
webpack-cli | 2.0.12 | 3.1.2

The upgrade of webpack modified our build files and included these
side effects:

* Our linter flagged the usage of bitwise operators in the build files
so I turned that off in our build file lint config (.eslintrc.es5.json)

* Our build file's size increased slightly from 12.1 KB to 12.13 KB
(gzip) so the package.json's bundlesize was updated accordingly.

No deleterious effects were noticed to popups running locally, but the
jump in webpack version included these notable changes:

* Switch from uglify-es to terser minimizer [1]

[1] https://github.com/webpack/webpack/releases/tag/v4.26.0

The upgrade for webpack-cli was a major version jump, but the params
that we pass to it in our package.json file appear to work as before.

diffs now correctly output errors. This will pick up changes to

--exit-code is passed to ensure that if there are changes then an

The dist folder became out of date as depending on what version
of node you run, the output is different.

To aid debugging, the script that checks the diff now outputs the
node version and the npm version. From now on, we will all have
to use the same node version to build assets.

This is annoying, but we will re-evaluate the approach we are taking
to build assets in T202743. We can easily work around this by all using
nvm and making consistent use of the same node version.

The assets have been rebuilt with the node version that CI uses.

Stephen Niedzielski ab7a5808ef Hygiene: update JSDoc boxed and JQuery types
Although Popups only uses JSDocs at this time which seemingly doesn't
care about casing[1], we should endeavor to use the proper return types.

This patch lowercases typing to indicate primitive / boxed type as
appropriate.[2] As a special case, function types are uppercased for
compatibility with TypeScript type checking.

Lastly, JQuery types are of type "JQuery". The global JQuery object's
identifier is "jQuery". This patch uppercases J's where appropriate.

Piotr Miazga 2527f931a2 Properly handle catch() when calling gateway fetch.
Previous implementation did not pass the `result` variable
to the catch() statement. Because of that every execution that
ended with exception inside fetch() statement was threated as
not a network exception and tried to present the null preview.

Changes:
 - properly handle data returned by rejected fetch promise
 - chaged the big if (result && result....) into something easier
 to read
 - pass Error object instead of 'http' string
 - Restbase can return exception, it doesn't have to handle the 404
 errors by itself, it's already taken care in the catch() logic
 - fixed unit tests to reflect new logic in restbase gateway

Stephen Niedzielski ce8a2d4c3f Update: cancel unused HTTP requests in flight
Whenever an HTTP request sequence is started, i.e. wait for the fetch
start time, issue a network request, and return the result, abort the
process if the results are known to no longer be needed. This occurs
when a user has dwelt upon one link and then abandoned it either during
the fetch start wait time or during the fetch network request itself.

This change is accomplished by preserving the pending promises in two
actions, LINK_DWELL and FETCH_START, and whenever the ABANDON_START
action is issued, it now aborts any previously pending XHR-like promise,
called a "AbortPromise" which is just a thenable with an abort() method.
There is a similar concept in Core:
ecc812f06e/resources/src/mediawiki.api/index.js.

Aborting pending requests has big implications for client and server
logging as requests are quickly canceled, especially on slower
connections. These differences can be observed on the network tab of
DevTools and the log in Redux DevTools.

Consider, for instance, the scenario of dwelling upon and quickly
abandoning a single link prior to this patch:

  BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_END STATSV_LOGGED ABANDON_END EVENT_LOGGED FETCH_COMPLETE

And after this patch when the fetch timer is canceled (prior to an
actual network request):

  BOOT EVENT_LOGGED LINK_DWELL ABANDON_START ABANDON_END EVENT_LOGGED

In the above sequence, FETCH_* and STATSV_LOGGED actions never occur.

And after this patch when the network request itself is canceled:

  BOOT EVENT_LOGGED LINK_DWELL FETCH_START ABANDON_START FETCH_FAILED STATSV_LOGGED FETCH_COMPLETE ABANDON_END EVENT_LOGGED

FETCH_FAILED occurs intentionally, STATSV_LOGGED and FETCH_COMPLETE
still happen even though the fetch didn't complete successfully, and
FETCH_END doesn't.

Additionally, since less data is transmitted, it's possible that the
timing and success rate of logging will improve on low bandwidth
connections.

Also, this patch tries to revise the JSDocs where possible to support
type checking and fix a call to the missing assert.fail() function in
changeListener.test.js.

Redux DevTools are available in all builds by passing the `?debug=true`
query string. Since globally enabling debug significantly slows load
times, also enable support when the build is non-production (debug)
which is known at transpile time. This enables a debuggable version of
Popups in an otherwise production-like MediaWiki without changing the
Popups release build product.

Also, update the readme with a couple debug tips and flip a few bullets
from hyphens to asterisks since that seems to be more prevalent.

Stephen Niedzielski 7c98c04e0b Fix: unwanted thumbnail spacing in RTL locales
Thumbnails are displayed as SVG image elements. The SVG itself has a
width 3px greater than necessary for landscape thumbnails specifically.
For left-to-right languages, this additional space is empty and
unnoticed. For right-to-left languages, this extra spaces shows as a gap
on one side of the thumbnail and exceeds the popup's bounds on the other
side.

This extra 3px appears to have been mistakenly applied to landscape
thumbnails when it is only applicable to portrait, for which it is
already accounted for. Remove the 3px slop.

Stephen Niedzielski 676faa3514 Hygiene: consolidate CSS class manipulation
• Instead of removing 'mwe-popups-no-image-tri' in
  renderer#layoutPreview(), add more conditions to #getClasses().

  The addition condition in getClasses() was:

    ( !hasThumbnail || isTall ) && !flippedY

  The removal condition in layoutPreview() was:

    flippedX && !flippedY && hasThumbnail && isTall

  To combine them, the removal logic is inverted and the conjunction is
  taken:

    ( ( !hasThumbnail || isTall ) && !flippedY ) &&
    !( flippedX && !flippedY && hasThumbnail && isTall )

  Push the negation inwards:

    ( !hasThumbnail && !flippedY || isTall && !flippedY ) &&
    ( !flippedX || flippedY || !hasThumbnail || !isTall )

  Expand:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY && flippedY ||
    !hasThumbnail && !flippedY && !hasThumbnail ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && flippedY ||
    isTall && !flippedY && !hasThumbnail ||
    isTall && !flippedY && !isTall

  Eliminate always false conditions and combine redundancies:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Further eliminate redundancies:

    !hasThumbnail && !flippedY ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Factor:

    !flippedY && (
      !hasThumbnail || isTall && !flippedX || isTall && !hasThumbnail
    )

  Factor more:

    !flippedY && (
      !hasThumbnail || isTall && ( !flippedX || !hasThumbnail )
    )

  Eliminate last redundancies:

    !flippedY && ( !hasThumbnail || isTall && !flippedX )

  The getClasses() test is updated for the new logic.

• Move thumbnail clip path manipulation from renderer#layoutPreview() to
  a new function, #setThumbnailClipPath(). The new function flips the
  order of the series of if statements so that an if / else block can be
  used instead which clarifies that clip-path state is exclusive. In
  other words:

    if ( a ) { foo.prop = 1; }
    if ( b ) { foo.prop = 2; }
    if ( c ) { foo.prop = 3; }
    if ( d ) { foo.prop = 4; }

  Can generically be refactored regardless of condition or value to:

    if ( d ) { foo.prop = 4; }
    else if ( c ) { foo.prop = 3; }
    else if ( b ) { foo.prop = 2; }
    else if ( a ) { foo.prop = 1; }

  Because prop was originally overwritten which implies if / else-like
  priority.

  Additionally:
  • The entire function call is wrapped in a hasThumbnail conditional
    which previously was checked as an input in each case.
  • Consolidate the last two conditions since they only differed by a
    single boolean input.
  • Move the setAttribute() action to the end of the function since the
    conditionals just map condition to value and the action is now
    identical.

• Revise pokey mask doc to use clip-path terminology. This inverts the
  thinking about the mask but better matches usage.

Stephen Niedzielski 2eeaa0a2e4 Hygiene: consolidate clip-path manipulation
The clip-path SVG property was conditionally set in thumbnail.js and
also conditionally set or removed in renderer.js. This patch refactors
the logic to occur in a single place, renderer.js.

The refactor was made with the following considerations:

• The one condition under which thumbnail.js would set clip-path was,
  given a thumbnail exists, the thumbnail was not tall and clip-path
  would be set to `url(#mwe-popups-mask)`. Otherwise, thumbnail.js would
  not set clip-path.

• The logic in renderer.js for setting the attribute doesn't change
  since overwriting the clip-path is equivalent to not having a
  preexisting value. The case for removing the attribute itself is
  replaced by inverting the condition, `flippedY`, and combining it with
  the thumbnail.js condition, `!isTall`. The operation is only valid for
  an existing thumbnail so the `hasThumbnail` remains unchanged.

This patch also clarifies that the "flipped" classes are exclusively set
by using an if / else chain instead of reconsidering all inputs for each
condition.

    -iname \*.js|
  xargs -rd\\n sed -ri 's%function\s*(\([^)]*\))%\1 =>%g'

  rg -slg\!/resources/dist/ -g\!/i18n/ -g\!/doc/ 'this|self|arguments|bind|call|apply|new'|
  xargs -rd\\n git difftool -y

Stephen Niedzielski d35286a064 Update: upgrade to Webpack 4 & improve output size
Upgrade from Webpack v2.0.12 to v4.1.1. There have been many changes to
Webpack... Noticeable in the bundle size is that a number of files are
now inlined and generally minification is improved.

Changes related to the upgrade include:

- Remove unsupported UglifyJS options which link back to T188081. These
  appear to have been anticipatory but never acted on and it isn't clear
  whether they even worked or not.
- Pass the -p plag for production optimizations; pass the -d flag since
  production doesn't support watching.
- NamedModulesPlugin is now on by default but only in development mode
  so no change was made.
- Webpack command line client now must be installed separated and
  appears in package.json as webpack-cli.

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

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

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.

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

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.

.catch is only available with jQuery 3, which is only now starting to
roll out (see https://phabricator.wikimedia.org/T124742)

This patch rolls back the usage of .catch introduced in
https://gerrit.wikimedia.org/r/#/c/373327/ to use .fail, but only the
source part, given that patch introduced unit tests for this behavior

Piotr Miazga f8498ce70c Store map files under .json extension
We cannot serve .map files from production servers. This makes
Popups extension difficult to debug. As a simplest solution we
decided to store map files as .json files so we can easily access
js maps files.

Changes:
 - changed webpack config to store map files under .json extension

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.

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 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

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)

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

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 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.

Supporting changes:
* Bundle assets with webpack@2.4.1.

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.
