Sam Smith 77943704f8 actions: Add token to PREVIEW_SHOW
Mirroring all other actions that are dispatched after some delay, add
the token to the PREVIEW_SHOW action.

Supporting changes:
* Pass the token to ext.popups.Preview#show so that it can be passed to
  actions#previewShow.

Sam Smith 87be4be855 reducers: Reduce FETCH_COMPLETE if token matches
... instead of using the active element.

In the case of the eventLogging reducer, this fixes scenario 4.1 from
T159490#3150331, which was caused by late FETCH_COMPLETE actions being
reduced regardless of whether interaction had been finalised or a new
interaction had started.

Sam Smith 52d128863e actions: Correctly delay FETCH_COMPLETE
I496fe317 caused a regression where the FETCH_COMPLETE was delayed for a
total of 650 ms rather than 500 ms. This is evidenced by a 150 ms step
in the median Time To Preview immediately after today's (Thursday, 6th
April) MediaWiki train [0].

jdlrobson f80acb978b renderer: Pass event to behavior for processing
I6d9ff52b introduced a regression where if a logged out user clicks the
settings cog then an error is thrown.

For now, passing the event to the behavior for further processing is
required. However, it's clear that this makes the
ext.Popups.PreviewBehavior abstraction leaky.

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 1e199b67f0 actions: Simplify delaying FETCH_COMPLETE
Require that two promises are resolved (or one is rejected) before the
FETCH_COMPLETE action is dispatched. The first promise represents the
gateway request and the second represents an arbitrarily long delay. If
the first resolves before the second, then there'll be a delay until the
second resolves; whereas if the first rejects, then there's no delay.

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.

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.

While we could manipulate either the thumbnail or original image URL,
there are subtle differences between the two, so manipulating the latter

both to require wait.js and mock using mock-require instead of the
global variable.

Additional changes:
* Fix FIXMEs about actions.js using the global mw.popups.wait instead of
  the require one.
* Fix the unit tests to use require mocking for wait.js instead of
  global variable mocking in both integration and actions tests
* Change tests that use deferreds and promises to be async qunit tests
  (Deferreds are asynchronous with jQuery in node, apparently they
  weren't in the browser)
* Change integration.test.js to use require on Redux and ReduxThunk

Sam Smith 938a4b85d4 Hygiene: Remove checkin instrumentation
The "checkin" part of the Popups schema was superseded by the
ReadingDepth schema, the implementation of which is tracked by T155639.

As well as removing all checkin-related code, update the Popups schema
to the latest version - the version that doesn't have the checkin
property.

joakin 2ca5fed3ee Tests: Migrate changeListeners/render.test.js to node-qunit
The render change listener is hard coupled to the renderer file, so in
order to migrate the test, instead of stubbing a global variable, we had
to either inject the renderer into the change listener factory as done
everywhere else, or mock the require call.

In order to do one thing per commit, we're mocking the require call
here to get the migration done, but added a FIXME to use dependency
injection instead in a future change.

Instead of using constructor functions, use factory functions to

* 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

As noted in the review of I71a8a84, creating a new object to represent

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.

Sam Smith 49ce7643f0 Hygiene: Remove link element from LINK_ABANDON_*
Initially, the link element was added to LINK_ABANDON_* to determine
when an interaction should be reset. However, this wasn't enough to
protect against timing-related bugs, e.g. T154923. Now that tokens are
used to determine when interactions should be reset, the link element
can safely be removed from the LINK_ABANON_* actions.

Supporting changes:
* Update the return type of mw.popups.actions.linkAbandon in its

I2ecf575b introduced a regression where the linkTitleChangeListener

joakin e49103061e Don't reset interaction info when dwelling back to a link
When dwelling back to a link, previously a new LINK_DWELL action would
be sent and the reducer would reset the interaction as if it was a new
one.

This shouldn't happen, since dwelling back to the active link (from
the preview, for example) is not a new interaction, and should not
create a new interaction or hide and show the preview.

With this change, the preview reducer has the notion of new or repeat
interactions, and only resets state on new ones, and only sets
isUserDwelling when dwelling on a the link of the current interaction.

Also when the interaction is repeat, we guard on the action creator and
don't trigger the wait or the fetch request.

joakin 36518b1215 Don't hide preview when user dwells on link
... after dwelling on preview.

Currently, the asynchronous PREVIEW_ABANDON_END action wouldn't be
ignored if the user were to have dwelled on the link that the preview is
about. The action is only ignored if the user is dwelling on the
preview, i.e. if preview.isUserDwelling is truthy.

Set preview.isUserDwelling to truthy if the user is dwelling either on
the link or on the preview.

While I1bf953b2 fixed the typo in FETCH_START_DELAY, it didn't do
anything to address the inconsistency in the time it takes to render a
preview (preview delay).

If the gateway result resolves before the target preview delay (500 ms)
is met, then delay dispatching the FETCH_END action until it is. If,
however, the gateway result resolves after the target preview delay,
then dispatch the FETCH_END action immediately.

canonical enabled state in the previews reducer, and by the settings
reducer to perform UI changes.

The enabled state of the application has been kept in the preview
reducer as the canonical source of truth. See supporting changes for
documentation about the decision.

Actions:
* Introduce new action SETTINGS_CHANGE with the enabled status
* Trigger that action when clicking Save in the settings dialog

Reducers:
* Listen to SETTINGS_CHANGE in the preview reducer to update enabled
  status
* On the settings reducer
  * Handle the SETTINGS_CHANGE action
  * Add showHelp flag to determine if the help should be showing

Change listeners:
* Switch to compare past vs present changes in the implementation
* Handle showing and hiding the help

Supporting changes:
* On the rendered settings dialog:
  * Change #hide to actually just hide and remove legacy if statement
  * Add #toggleHelp method to show or hide the help dialog
* Add doc/adr/0003-keep-enabled-state-only-in-preview-reducer.md to
  support the decision of making the saveSettings action creator return
  a Redux.Thunk and keeping the enabled state just in the preview
  reducer.
  * Add NB to actions#saveSettings explaining and linking to the

Sam Smith bbeb618e1d Store/update user's preview count
Action changes:
* Add the PREVIEW_SHOW action.

Changes:
* Dispatch the PREVIEW_SHOW action when the preview has been shown.
* Add the previewCount change listener, which is responsible for
  persisting the user's preview count to storage when it changes.
* Call the change listener factories individually in
  #registerChangeListeners as their signatures aren't consistent.

joakin ab4eff82e4 Don't use $.extend in nextState to preserve undefined fields
Since the state was cloned into an empty object with $.extend, undefined
properties were being deleted from it, not actually preserving those
keys. So:

         nextState({hi: undefined, ho: 1}, {ho: 2})
         //> {ho: 2}

It seems like a more consistent behavior would be to not lose any own
keys on the state as we do with the updates too, so that:

         nextState({hi: undefined, ho: 1}, {ho: 2})
         //> {hi: undefined, ho: 2}

Which is what this commit does by not using $.extend to clone the state
and instead just manually copy the keys to the new object, even the
undefined ones.

Sam Smith 27334437fb Hygiene: Don't fall through unless necessary
The preview reducer would treat the LINK_ABANDON_END and
PREVIEW_ABANDON_END actions as the PREVIEW_DWELL action. Fortunately,
this was a NOOP as they would only fall through if the preview was being
dwelled upon.

joakin 7cf3339f00 Hygiene: #nextState explain why we iterate keys to copy
It would seem that nextState should be $.extend({}, state, updates), but
as it was noted in the commit message that introduced the function
$.extend doesn't copy undefined|null values and that's why we iterate
manually over updates to copy any prop that exists over. That way we can
override properties to null|undefined in the state.

This commit expands the comment to explain so, and why OO.copy couldn't
be used.

joakin e976af78e2 Hygiene: #processLinks Only use global variables at the edges
Instead of defaulting the config to the global mw.config when the param
is not defined, always pass it in (it is called just once in application
code), that way there's no need to test for the optional argument
behavior and the function is pure.

Sam Smith e4719c4918 Don't hide preview if it's interacted with
Action creator changes:

  two distinct actions, LINK_ABANDON_START and _END, the latter of which
  is dispatched after a 300 ms delay.
* Introduce the previewDwell and previewAbandon action creators. The
  latter is an asynchronous action that mirrors the linkAbandon action.

Reducer changes:
* Make the LINK_DWELL, LINK_ABANDON_END, and PREVIEW_ABANDON_END action
  hide a preview, if one has been shown.
* Make the LINK_ABANDON_END action NOOP if:
  * The user has interacted with another link, or
  * The user is interacting with the preview.

Supporting changes:
* Update the mw.popups.reducers#preview and #renderer unit tests to use
  an empty previous state so that the tests are more resilient to
  modifications of the state tree.
