Since the state was cloned into an empty object with $.extend, undefined
properties were being deleted from it, not actually preserving those
keys. So:
nextState({hi: undefined, ho: 1}, {ho: 2})
//> {ho: 2}
It seems like a more consistent behavior would be to not lose any own
keys on the state as we do with the updates too, so that:
nextState({hi: undefined, ho: 1}, {ho: 2})
//> {hi: undefined, ho: 2}
Which is what this commit does by not using $.extend to clone the state
and instead just manually copy the keys to the new object, even the
undefined ones.

Changes:
* Make the gateway handle missing pages, which are characterised by the
MediaWiki API response having both the missing property set to truthy
and the page not having any revisions.
* Add the preview-empty template and associated "mwe-popups-is-empty"
CSS class, which describe what an empty preview contains and how it
should look.
Supporting changes:
* Move the original preview template into the ext.popups module.

The preview reducer would treat the LINK_ABANDON_END and
PREVIEW_ABANDON_END actions as the PREVIEW_DWELL action. Fortunately,
this was a NOOP as they would only fall through if the preview was being
dwelled upon.

As it is, that test is passing the same previous state and current state
because extend by default only copies one level deep, resulting in the
manual mutation mutating both prev and current state.
This passes because the change listener always sets the link visibility
from the current state regardless of the previous state (it is doing
redundant work, but not too much).

It would seem that nextState should be $.extend({}, state, updates), but
as it was noted in the commit message that introduced the function
$.extend doesn't copy undefined|null values and that's why we iterate
manually over updates to copy any prop that exists over. That way we can
override properties to null|undefined in the state.
This commit expands the comment to explain so, and why OO.copy couldn't
be used.

Instead of defaulting the config to the global mw.config when the param
is not defined, always pass it in (it is called just once in application
code), that way there's no need to test for the optional argument
behavior and the function is pure.

Like the next test also does, so that in case it fails we get some info
given the assert result doesn't match the test title.

Given this UI elements are going to change this comment would get
outdated really soon. Instead refer to generic interaction.

I59ac2e32 removed support for non-SVG capable UAs but didn't remove all
of the associated styles.
Additional changes:
* Give the inner container a name, "mwe-popups-container", so that it
can be styled with reduced specificity.
Supporting changes:
* Move the "core" styles into the ext.popups module.

I14b437e7 introduced a regression where neither the preview's thumbnail
nor extract linked to the page.
Change-Id: I51793640d882aec711af8683ffbea794fad1b047
Action creator changes:
* Make the linkAbandon action creator asynchronous by splitting it into
two distinct actions, LINK_ABANDON_START and _END, the latter of which
is dispatched after a 300 ms delay.
* Introduce the previewDwell and previewAbandon action creators. The
latter is an asynchronous action that mirrors the linkAbandon action.
Reducer changes:
* Make the LINK_DWELL, LINK_ABANDON_END, and PREVIEW_ABANDON_END action
hide a preview, if one has been shown.
* Make the LINK_ABANDON_END action NOOP if:
* The user has interacted with another link, or
* The user is interacting with the preview.
Supporting changes:
* Update the mw.popups.reducers#preview and #renderer unit tests to use
an empty previous state so that the tests are more resilient to
modifications of the state tree.

I14b437e7 introduced a regression where the `moment`ed last modified
timestamp wasn't rendered.
Additional changes:
* Remove the HTML comments from the preview template.

If the user abandons the link after the API request delay (500 ms) but
before the it resolves (~10e3 ms), then the preview shouldn't be
rendered.
Changes:
* actions: Include the link in the FETCH_START, FETCH_FAILED, and
FETCH_END actions.
* reducers: If the active link has changed, then FETCH_END is a NOOP.
Supporting changes:
* reducers: Signal that a preview should be rendered and shown with
preview.shouldShow.
Change-Id: I3dd1c0c566ec63de515174c14845d7927583ce93
The QUnit test suite now completes in ~10e2 ms rather than ~10e3 ms.
Changes:
* Make mw.popups.actions#linkDwell to use mw.popups.wait.
* Make the tests for mw.popups.actions#linkDwell complete faster, but
still asynchronously, by stubbing mw.popups.wait.
Change-Id: I5cbef0ea69bc860f75cac27c1adea3d419c1ffad
Changes:
* Reduce the fade-in animation delay to 200 ms.
* Truncate a long extract by fading it out gradually.
* Increase the depth of the shadow cast by a preview and remove its
border.

Extract core rendering functionality from the mw.popups.renderer and
mw.popups.renderer.article objects.
For now, render and show the preview when the user dwells on and
abandons a link respectively.
Supporting changes:
* Add mw.popups.wait, which is sugar around window.setTimeout.
* action.response -> action.result in the FETCH_END case of the preview
reducer.
Change-Id: I14b437e7c2f55b988837fcb2800dd61a23c29a01
Supporting changes:
* Remove the preview.previousActiveLink property from the state tree as
it's unnecessary.
Change-Id: I657decf9425a7a9e2b27a798ed60b162569661d8
OO.copy doesn't copy Element instances, whereas $.extend does. However,
OO.copy does copy properties whose values are undefined or null, whereas
$.extend doesn't.
Since the state tree contains an Element instance - the
preview.activeLink property - we need to use $.extend.
Add the nextState helper function which copies the current state tree
with $.extend and mixes in all updates manually.

If the user has abandoned the link or dwelled on a different link, then
don't make the API request.
Changes:
* Fix a bug in the linkDwell reducer where the activeLink was always
being set to undefined.
* Add the private fetch action creator.
* Make the linkDwell action dispatch the result of the fetch action
creator after 500ms.
Supporting changes:
* Make the link* action creators take DOM elements rather than jQuery
instances so that:
1. Testing whether the state tree has changed is an identity
comparison.
2. jQuery instances are constructed only when required.
* Document the ext.popups.Gateway type.
* Document the Redux.Store type.
* Rename the "previews-page-title" data attribute to
"page-previews-title" to avoid confusion.
Change-Id: I0b1cf3337a6f8d6450ad2bd127cb292ebb73af4f
Supporting changes:
* Add mw.popups.registerChangeListener, which registers a change
listener that will only be called when the state in the store has
changed.
Change-Id: Ibe6934058327c7f02f7d8092e74a667a5a1c600a
Changes:
* Add sessionToken and pageToken properties to the BOOT action and
update the preview reducer.
Supporting changes:
* Move the mw.popups.createActions to ext.popups/boot.js so that Redux
is used in one file and the actions can be tested in isolation more
easily.

Reducers as a whole are a WIP, but this implements a baseline from which
to add more.
Changes:
* Create ext.popups.reducers to house all reducers
* Create reducers for preview and renderer state manipulation
* Create rootReducer by combining preview and renderer reducers
* Add QUnit tests for reducers
* Move action types into ext.popups.actionTypes
* Extract rootReducer from boot.js
Change-Id: I8a2296c6846cd4b0552a485e671af1d974944195
Supporting changes:
* Automatically register JavaScript files in the
tests/qunit/ext.popups/ directory.
Additional changes:
* Fix a grammatical error in the docblock for
mw.popups.createExperiment.
