Jon Robson 2c09fd1d1c Generalize settings code (attempt 2)
This reverts commit a6a65204c6.
to restore custom preview types.

-- Changes since revert
The previous patch accidentally removed the syncUserSettings
changeListener. This has now been restored with several modifications:
* We have a migrate script which rewrites existing localStorage settings
to the new system
* The existing save functions are generalized.

The changes since this patch are captured in
Ia73467799a9b535f7a3cf7268727c9fab7af0d7e

-- More information

A new REGISTER_SETTING action replaces the BOOT action for
registering settings. This allows custom preview types to be
associated with a setting. They do this by adding the enabled
property to the module they provide to mw.popups.register

Every time the new action is called, we refresh the settings
dialog UI with the new settings.

Previously the settings dialog was hardcoded, but now it is generated
from the registered preview types by deriving associated messages
and checking they exist, so by default custom types will not show
up in the settings.

Benefits:
* This change empowers us to add a setting for Math previews to allow
them to be enabled or disabled.
* Allows us to separate references as its own module

Additional notes:
* The syncUserSettings.js changeListener is no longer needed as the logic
for this is handled inside the "userSettings" change listener in response to
the "settings" reducer which is responding to
SETTINGS_CHANGE and REGISTER_SETTING actions.

Upon merging:
* https://www.mediawiki.org/wiki/Extension:Popups#Extensibility will be
updated to detail how a setting can be registered.

Jon Robson 9aa07d0809 Model: Make dwell delay part of model and registration
Dwell delay varies between popup type so should be part of the
definition. Since this is needed by reference tooltips we should
make this part of the Page preview model. This will allow us to
separate concerns of the architecture and reference  tooltips
for better maintenance between WMDE and web team.

We added reference preview as a checkbox the the
anonymous user settings. To handle both popup types
(pages and references), we changed the usage of
preview.enabled. We pass on all types as a map
inside preview.enabled. The footer link to edit the
settings will appear for anonymous users if at least
one type is disabled.

The main motivation here is to dramatically reduce the number
of places that use the same property name "enabled" for values
on different objects (e.g. "state", "actions", and "updates"
are all different things) with slightly different meanings. I
tried hard to come up with names that reflect better what each
meaning is.

Noam Rosenthal 4492b54a44 Performance optimization for popup rendering
Reduce layout/style thrashing by measuring all required geometries
at event handler, not waiting for delays/redux/style changes.

Use CSS bottom instead of top, to avoid having to measure the popup
before positioning it, if it's placed above the link ("flippedY").

Disable some test cases that relied on implementation detail of using
"top" CSS.

Thiemo Kreuz 065a8e9631 Fix action reducer forgetting *all* duplicate dwell actions
I was able to track the issue down to the changes made in this patch:
https://gerrit.wikimedia.org/r/331563

This patch is mostly a simplification of ce8a2d4
(I9a73b3086fc8fb0edd897a347b5497d5362e20ef):

- Don't make wait#wait() abortable. This adds complexity and isn't
  needed since the token is rechecked in the .then() of
  actions#linkDwell(). The request is permitted to continue and fetch if
  that token still matches and is never issued otherwise.

  Once a request has been issued, that request is still abortable.
  However, note that calling XHR.abort() is just a request to abort and
  may not be granted. Whether or not XHR.catch() is invoked is what
  dispatches the FETCH_ABORTED action (or doesn't if the request to
  abort was denied).

- Remove the abort tests for wait#wait() since the functionality is no
  longer provided.

- Pass the preview token in the FETCH_ABORTED action and reduce
  FETCH_ABORTED the same way as ABANDON_COMPLETE in reducers/preview.

The follow-up patch, I3597b8025f7a12db0cf5d83cce5a77abace9bae3, adds
integration tests for the specific bug fix. Note that these Selenium
tests are incompatible with the content proxy, so it is probably best to
simply unset $wgPopupsRestGatewayEndpoint and $wgPopupsGateway and allow
the defaults to be used. Also note that the tests are incompatible with
recent versions of Node.js (so use NVM) and emit many deprecation
warnings (so set deprecationWarnings to false in
tests/selenium/wdio.conf.js) An example run of the tests looks something
like:

  chromedriver --url-base=wd/hub --port=4444 &
  # If any changes are made locally, also run `npm -s start &`.
  MW_SERVER=http://localhost:8181 \
  MEDIAWIKI_USER=foo \
  MEDIAWIKI_PASSWORD=bar \
  DISPLAY= \
  npm -s run selenium-test

Live testing may be performed as well. Remember that RESTBase requests
are incompatible with MobileFrontend's content proxy hack so ensure to
comment it out if $wgPopupsGateway is configured for RESTBase (see
T218159).

1. Open the DevTools network tab.
2. Disable the browser cache. Chromium, at least, won't abort requests
   coming form the cache.
3. Hover back and forth quickly over a preview. In Chromium, canceled
   requests are labeled and appear red. This is a good scenario to test.
   With the patch, a preview should always be shown when ultimately
   resting on a link. Without the patch, it is possible to rest upon the
   link with no preview showing. This may require several attempts.

WMDE-Fisch 1879a4d59e Show referencePreviews on click
Introducing the REFERENCE_CLICK action that will fetch and show the
preview for the clicked reference right away without any delay.

The main goal of the new chain of events introduced with the reference
click is showing the reference preview right away. The actions triggered
by the dwelling include delays in multiple parts of the process.

If there's a dwell action-chain in progress when the click action is
executed, the related promise ( that might still include steps with
delays ) and the reference preview is retrieved and shown right away
re-using the token. 

In the case where there's no dwell action running ( e.g. when the click
was triggered via touch ) we create a new token and start from scratch.

In either case we want to avoid, that multiple clicks trigger multiple
actions and abort early when there's already a click action in progress.

Thiemo Kreuz 8305eb8634 Minimize createStubTitle() helper method
Pretty much all usages of this function do *not* use the second
parameter to pass a page name prefixed with a namespace, but pass the
page name only.

This patch here removes the redundancy. The namespace prefix is now a
generated one, saying "Namespace <number>:…". It turns out no test
relies on this so far.

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?

it, the page tokens would now be consistent with the ReadingDepth

there is no centralised API.

Piotr Miazga c823a0e6cb When request gets aborted it shouldn't finish with FETCH_FAILED
Whe user moves mouse away and we abort the http request we shouldn't
count that request as a FETCH_FAILED. The reasoning behind is that
FETCH_FAILED state increments the counter.PagePreviewsApiFailure.
Our StatsD graph gets polluted with lots of aborted requests and it
becomes unsuable. It doesn't show only the failed requests.

Changes:
 - introduced new state: FETCH_ABORTED
 - switch to FETCH_ABORTED when browser aborts the request

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.

Sam Smith 35daa2a689 Hygiene: Page view -> Pageview
Pageview is consistent with verbiage used by Research and Analytics
Engineering in their reports and documentation, e.g.
https://wikitech.wikimedia.org/wiki/Analytics/Pageviews.

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

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+
compatible `.catch`.

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

See bug for more general proposal for eslint-wikimedia-config.

joakin c6efe18f6a Restore test subject
Test subject was changed and stopped matching the implementation. In
this particular change the test (a bit convoluted but) tests that wait
is called appropriately, which is why the subject read "should delay
dispatching ..."

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 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.
