Stephen Niedzielski ece4670710 Hygiene: use arrow for anonymous functions
In some places, the arrow function seems more natural. This patch
approximates the following with manual amendments:

  find \
    -not \( \( -name node_modules -o -name .git -o -name vendor -o -name doc -o -name resources \) -prune \) \
    -iname \*.js|
  xargs -rd\\n sed -ri 's%function\s*(\([^)]*\))%\1 =>%g'

Files to focus on were identified with:

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

jdlrobson f5f21a8d09 RESTBase url is configurable
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

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.

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

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.

joakin e6081106f1 Use EcmaScript modules instead of common.js modules
Why: Because they are the approved standard by TC39 and Ecma for
JavaScript modules.

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

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

Piotr Miazga f2fbef6ec7 Implement html/rest.js gateway which handles HTML Restbase responses
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

Page Previews should be able to consume HTML response generated by
MediaWiki. First we need to move out plain text crunching from
renderer.js and model.js. Mediawiki and Restbase gateways will have
to parse/htmlize plaintext into nice HTML by themselves.

Sam Smith 568b7a09a1 rest: Always scale thumbnail's largest dimension
... thumbnails.

A good example of the difference in behaviour of the PageImages API is
here <T156800#3087507>. The API defers to File#transform, which scales
the largest dimension of an image, not always the width, e.g. if an
image is 1000px x 2000px and the request is for a thumbnail "of 1800px",
then the thumbnail will be 900px x 1800px.

Sam Smith d4caff9774 rest: Don't scale unscalable thumbnails
If the image isn't an SVG then it shouldn't be scaled past its original
dimensions. Handle the case where the requested thumbnail can't be
generated on the server as the original is too small ( < 320px,
currently [0]) in the same way.

Moreover, if the image happens to have the exact dimensions that we're
requesting (300px or 600px wide, currently [1]), then use the original
image to avoid unnecessary work/pressure on caches.

Supporting changes:
* Update the SVG_RESTBASE_RESPONSE fixture to use the extension returned
  by RESTBase (and the PageImages extension) for the thumbnail:
  .svg.png.

Sam Smith 720cfbdcd7 restbase: Use thumbnail when generating thumbnail
Rather than manipulating the URL of the original image to get the URL of
the appropriately sized thumbnail, manipulate the URL of the thumbnail
image.

While we could manipulate either the thumbnail or original image URL,
there are subtle differences between the two, so manipulating the latter
makes the generateThumbnailData function as simple as possible, e.g. we
don't have to splice in "/thumb" after "/commons".

Also, ensure that the thumbnail's dimensions are scaled appropriately.
