Stephen Niedzielski 4ce0246d78 Hygiene: replace jQuery.noop dependency
Replace $.noop dependency with inline empty function.

The tests relied on a single function instance to pass. A toString()
comparison of the noop function cannot be used as they differ when
coverage is enabled.

Nick Ray 2ed5587945 Upgrade stylelint-config-wikimedia and remove stylelint
The following upgrade was made:

stylelint-config-wikimedia | 0.4.3 | 0.5.0

The upgraded version stylelint-config-wikimedia includes stylelint as a
dependency (no longer a peer dependency) [1] so our stylelint dependency was
removed.

As a result of this upgrade, several of our .less files were flagged by
the linter and corrected in this patch.

Stephen Niedzielski c7e742743b Doc: fix fetch delay comments
FETCH_COMPLETE_TARGET_DELAY is used to introduce an artificial delay to
HTTP requests as needed. However, FETCH_START_DELAY is always accounted
for so it makes sense to define FETCH_COMPLETE_TARGET_DELAY with it. The
docs are updated to draw the distinction between total delay and API
response delay.

jdlrobson 53d1a2c329 Use getPageviewToken api
Currently the Popups schema is disabled but if we were to re-enable
it, the page tokens would now be consistent with the ReadingDepth
schema

The getToken function is kept to allow generation of the
pageInteractionToken's relating to a link interaction, for which
there is no centralised API.

Additional changes:
* I've updated various tests to use the central mw.user stub to make
clearer where tokens come from.

jQuery.hidpi was deprecated by T127328
(https://gerrit.wikimedia.org/r/441614). This repo used the
"bracketedDevicePixelRatio" function from that plugin. Since browser
compatibility is good now for window.devicePixelRatio, this commit adds
a function which relies on that instead.

Stephen Niedzielski ab7a5808ef Hygiene: update JSDoc boxed and JQuery types
Although Popups only uses JSDocs at this time which seemingly doesn't
care about casing[1], we should endeavor to use the proper return types.

This patch lowercases typing to indicate primitive / boxed type as
appropriate.[2] As a special case, function types are uppercased for
compatibility with TypeScript type checking.

Lastly, JQuery types are of type "JQuery". The global JQuery object's
identifier is "jQuery". This patch uppercases J's where appropriate.

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

jenkins-bot 147f5a4fa1 Merge "Properly handle catch() when calling gateway fetch." 2018-07-12 22:47:07 +00:00
Piotr Miazga 2527f931a2 Properly handle catch() when calling gateway fetch.
Previous implementation did not pass the `result` variable
to the catch() statement. Because of that every execution that
ended with exception inside fetch() statement was threated as
not a network exception and tried to present the null preview.

Changes:
 - properly handle data returned by rejected fetch promise
 - chaged the big if (result && result....) into something easier
 to read
 - pass Error object instead of 'http' string
 - Restbase can return exception, it doesn't have to handle the 404
 errors by itself, it's already taken care in the catch() logic
 - fixed unit tests to reflect new logic in restbase gateway

 - added acceptLanguage as a config option passed to
 both mwApi and restbaseApi, by default code will use
 the language defined in `wgContentLanguage` config
 variable. The `wgContentLanguage` is always defined
 (see ResourceLoaderStartUpModule::getConfigSettings())
 so there is no need for checking the variable existence.

The new logic was tested both on MediaWiki API and Restbase API

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.

Stephen Niedzielski 89e592183f Hygiene: enable Redux DevTools for debug builds
Redux DevTools are available in all builds by passing the `?debug=true`
query string. Since globally enabling debug significantly slows load
times, also enable support when the build is non-production (debug)
which is known at transpile time. This enables a debuggable version of
Popups in an otherwise production-like MediaWiki without changing the
Popups release build product.

Also, update the readme with a couple debug tips and flip a few bullets
from hyphens to asterisks since that seems to be more prevalent.

Stephen Niedzielski 7c98c04e0b Fix: unwanted thumbnail spacing in RTL locales
Thumbnails are displayed as SVG image elements. The SVG itself has a
width 3px greater than necessary for landscape thumbnails specifically.
For left-to-right languages, this additional space is empty and
unnoticed. For right-to-left languages, this extra spaces shows as a gap
on one side of the thumbnail and exceeds the popup's bounds on the other
side.

This extra 3px appears to have been mistakenly applied to landscape
thumbnails when it is only applicable to portrait, for which it is
already accounted for. Remove the 3px slop.

Stephen Niedzielski 676faa3514 Hygiene: consolidate CSS class manipulation
• Instead of removing 'mwe-popups-no-image-tri' in
  renderer#layoutPreview(), add more conditions to #getClasses().

  The addition condition in getClasses() was:

    ( !hasThumbnail || isTall ) && !flippedY

  The removal condition in layoutPreview() was:

    flippedX && !flippedY && hasThumbnail && isTall

  To combine them, the removal logic is inverted and the conjunction is
  taken:

    ( ( !hasThumbnail || isTall ) && !flippedY ) &&
    !( flippedX && !flippedY && hasThumbnail && isTall )

  Push the negation inwards:

    ( !hasThumbnail && !flippedY || isTall && !flippedY ) &&
    ( !flippedX || flippedY || !hasThumbnail || !isTall )

  Expand:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY && flippedY ||
    !hasThumbnail && !flippedY && !hasThumbnail ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && flippedY ||
    isTall && !flippedY && !hasThumbnail ||
    isTall && !flippedY && !isTall

  Eliminate always false conditions and combine redundancies:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Further eliminate redundancies:

    !hasThumbnail && !flippedY ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Factor:

    !flippedY && (
      !hasThumbnail || isTall && !flippedX || isTall && !hasThumbnail
    )

  Factor more:

    !flippedY && (
      !hasThumbnail || isTall && ( !flippedX || !hasThumbnail )
    )

  Eliminate last redundancies:

    !flippedY && ( !hasThumbnail || isTall && !flippedX )

  The getClasses() test is updated for the new logic.

• Move thumbnail clip path manipulation from renderer#layoutPreview() to
  a new function, #setThumbnailClipPath(). The new function flips the
  order of the series of if statements so that an if / else block can be
  used instead which clarifies that clip-path state is exclusive. In
  other words:

    if ( a ) { foo.prop = 1; }
    if ( b ) { foo.prop = 2; }
    if ( c ) { foo.prop = 3; }
    if ( d ) { foo.prop = 4; }

  Can generically be refactored regardless of condition or value to:

    if ( d ) { foo.prop = 4; }
    else if ( c ) { foo.prop = 3; }
    else if ( b ) { foo.prop = 2; }
    else if ( a ) { foo.prop = 1; }

  Because prop was originally overwritten which implies if / else-like
  priority.

  Additionally:
  • The entire function call is wrapped in a hasThumbnail conditional
    which previously was checked as an input in each case.
  • Consolidate the last two conditions since they only differed by a
    single boolean input.
  • Move the setAttribute() action to the end of the function since the
    conditionals just map condition to value and the action is now
    identical.

• Revise pokey mask doc to use clip-path terminology. This inverts the
  thinking about the mask but better matches usage.

Piotr Miazga 321d6348e1 Page_title and source_title should be in canonical form
We change page_title and source_title as a last step
just before we send the event.

Doing it elsewhere is risky at the current time because:
* the non-canonical form is needed for
mwApiGateway to bold title (formatPlainTextExtract). Needing both
would require updates to the Page model.
* title is used by EventLogging (Schema:Popups)

jdlrobson 44b49ab163 Drop second requestIdleCallback call
We already request an idle callback when loading the code in the init
module.
Doing so here seems redundant.

Stephen Niedzielski 2eeaa0a2e4 Hygiene: consolidate clip-path manipulation
The clip-path SVG property was conditionally set in thumbnail.js and
also conditionally set or removed in renderer.js. This patch refactors
the logic to occur in a single place, renderer.js.

The refactor was made with the following considerations:

• The one condition under which thumbnail.js would set clip-path was,
  given a thumbnail exists, the thumbnail was not tall and clip-path
  would be set to `url(#mwe-popups-mask)`. Otherwise, thumbnail.js would
  not set clip-path.

• The logic in renderer.js for setting the attribute doesn't change
  since overwriting the clip-path is equivalent to not having a
  preexisting value. The case for removing the attribute itself is
  replaced by inverting the condition, `flippedY`, and combining it with
  the thumbnail.js condition, `!isTall`. The operation is only valid for
  an existing thumbnail so the `hasThumbnail` remains unchanged.

This patch also clarifies that the "flipped" classes are exclusively set
by using an if / else chain instead of reconsidering all inputs for each
condition.
