Allow developers to use different endpoints for summaries
= developer happiness
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

* 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.

* The 'help' parameter expects a string, not a Message object. It
seemed to be working, but caused fatals when switching the
preferences form to the OOUI implementation (T117781).
* Use 'help-message' instead, which also avoids using the global
request context for Message objects.

This caused random extensions to not be able to load any ResourceLoader
modules (or do other things) on a random subset of pages and wikis.

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.

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.
* src/gateway/index.js defines gateways by configuration name stored
in extension.json

Tests are basically unchanged, except for some stubs on beforeEach.
Supporting changes:
* Bring stubs from the mediawiki library for mw.Uri,
mw.Title.newFromText and mw.RegExp into stubs.js
* Remove hook onResourceLoaderTestModules given there are no resource
loader test modules after migrating processLinks.test.js
Why bring stubs from real source? This is not optimal. It could be the
case that the stubs would need to be updated at some point in the
future. That's why in the comment of each stub, it is specified where it
came from, and what was changed to make it work. It is not optimal but
it should help with a future update if necessary.
Also checked the history of the stubs and these three stubs are very
stable with a small commits per year, usually adding some extra
functionality (not breaking changes) (the rest of the commits are
docs/format stuff), so the core behavior that we rely on here shouldn't
change in a fundamental way. See the github links:
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Uri.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Title.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.RegExp.js
Right now this stubs allow us to bring the test to run in isolation in
node.
The initial plan was to do change the test to be less test-case oriented
with dependencies on mediawiki.*.js and not to bring fake "real" stubs,
but after looking into it, given that:
1. the test cases in the test seem pretty informative showing the kind
of links that popups accepts
2. the stubs are acceptably easy to bring in, and are pretty stable
I decided to go with this approach initially to finish the migration
without changing the meaning of the tests.
If we want to remove the stubs and morph the test to verify stub calls
and move the test cases to documentation on the source, I'll tackle that
on a future commit.
Bug: T160406
Change-Id: Ieea378c9b7fec9116222b4a099c226d1f1131f65
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.

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.

* Logged in users bypass bucketing. They keep working as before.
* When Page Previews is configured as a beta feature, logged out users
won't see the feature.
* If an anonymous user has enabled/disabled the feature using
the settings cog then they will see or not see the feature
depending on the value of their setting.
* The other anonymous users are bucketed. By default 90% of these
users see the feature, the other 10% don't. These numbers can be
controlled by the config variable `wgPopupsAnonsEnabledSamplingRate`.

I225019b8 introduced a regression where empty Resource Loader modules,
i.e. modules without any scripts, were being added in the
ResourceLoaderTestModules handler because the base directory wasn't
