this particular change the test (a bit convoluted but) tests that wait
is called appropriately, which is why the subject read "should delay
dispatching ..."

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.

Change-Id: I0600dbc2e4d51a13675041d3c0741a793f4eae37
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.

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.

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.

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

* Make npm run test:node run only .test.js test files so that it
doesn't run the stubs.js or run.js file.

Following on from I4f653bba, since the schema and statsvInstrumentation
modules are similar, let's group/rename them:
schema -> instrumentation/eventLogging
statsvInstrumentation -> instrumentation/statsv
Change-Id: Ic59e0da7d4917f6733fd090f15d3c269af863f05
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.

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

npm scripts are run under sh. globstar support is only available in bash

This made the test mediawiki.test.js not run since it was moved to the
3rd level deep folder (and actually broke), resulting in:
208 tests

With this change, it fixes getting the test files, and fixes the
mediawiki.test.js, resulting in:

This makes it work everywhere and as nested as it will get for now. Will
consider adding glob support to mw-node-qunit later for easier use in

Refactor existing Restbase gateway and extract shared logic into
shared Restbase provider. Also introduced new createNullModel()
which defines an empty preview model.
Additionally improve naming in new gateways/formatter so function
names are more explicity.
* Htmlize() became formatPlainTextExtract() as it should be used
only with plain text extracts
* removeEllipsis() became removeTrailingEllipsis() as it removes
only trailing ellipsis.

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)
