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)

The eventLogging change listener is responsible for ensuring that the
internal state of Page Previews matches its external state (that
perceived by the user and UA). It does this by logging events with
ext.eventLog.Schema#log. This makes it the perfect place to track and
discard duplicate events enqueued by the Page Previews codebase observed
in T161769.
Make the change listener track events that it's logged by storing hashes
of the dynamic parts of them in memory. If the eventLogging change
listener sees the same event more than once, then it discards it and
increments a counter in StatsD.
This behaviour should be enabled for a matter of days as we should see
whether the duplicate events are being enqueued by the Page Previews
codebase immediately.

the behaviour of the change listener by passing in a function which

Moreover, sharing the analytics tracking function with other components
is simpler as there's no repeated code.

request, which is allowed to complete regardless of whether or not the
response is required.
If the user abandons the link but the request completes before the

... the interaction.
Following on from Iccba3c4c, LINK_CLICK shouldn't be considered the end
of an interaction because the link or preview can still be abandoned by
the user. Unlike ABANDON_END and LINK_DWELL, therefore, LINK_CLICK
musn't destroy the interaction but indicate that no more events should
be enqueued for the interaction.
More concretely, if the user has clicked the link or the preview, then
a "dwelledButAbandoned" or "dismissed" event shouldn't be logged.
Changes:
* Distinguish between "finalizing" and "closing" an interaction, where
the latter is the current behavior of ABANDON_END, LINK_DWELL, and
LINK_CLICK, in the eventLogging reducer and associated tests.

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

Like the FETCH_COMPLETE and ABANDON_END actions, the PREVIEW_SHOW action
was delayed but not conditionally reduced. As ABANDON_END is delayed,
there's a potential for a race and if ABANDON_END is reduced before
PREVIEW_SHOW, then there's no interaction to reduce the action into,
which causes an error, e.g. T159490#3165276 and T162373. Making

When EventLogging is unavailable do not initialise the EL-related code

When EL is enabled for a brand new user we request an additional module
during boot causing an additional HTTP request. Page Previews continues
to boot normally regardless of whether the request fails.
This approach doesn't impact boot or first paint time. Once the module

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

... 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.

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.

Now that most unit tests are run in node with common.js for loading
sources there is no reason to keep global variables around exposing all
the sources.
Only exception is the only qunit integration test processLinks.test.js
which still consumes mw.popups.processLinks, which is the only global
variable remaining in the codebase.
Changes:
* Remove references to mw.popups in code comments and reference the JS
file instead
* Remove popups.js which exposes all common.js modules as global
variables
* Export mw.popups.processLinks in processLinks.js for testing in
processLinks.test.js

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.

Because of the globals mw.popups.wait usage and mocking in both actions

the require one.
* Fix the unit tests to use require mocking for wait.js instead of
global variable mocking in both integration and actions tests

The render change listener is hard coupled to the renderer file, so in
order to migrate the test, instead of stubbing a global variable, we had
to either inject the renderer into the change listener factory as done
everywhere else, or mock the require call.
In order to do one thing per commit, we're mocking the require call
here to get the migration done, but added a FIXME to use dependency
injection instead in a future change.

Instead of using constructor functions, use factory functions to
generate the gateway objects, because of:
* Consistency on the approach in the repository, no constructor
functions are used, the factory function pattern prevales.
* Real private data with closures
* No use of `this`, which is dynamic and unbound in JS and a source of
errors. In contrast, by using a factory function, the
function/methods-of-the-object are tightly bound to the internal data.
Additional changes:

clarity on the intent of the parameter
* From: @param {jQuery} api

As noted in the review of I71a8a84, creating a new object to represent
the thumbnail is confusing. It's also somewhat wasteful.
Since both the MediaWiki API and RESTBase both agree on using "source"
as the key for the thumbnail's URL, it's reasonable to use it in the
gateway and renderer.
Bug: T152004
Change-Id: Ie1346d13b6e88004b817f5968448188ed83cfda4
After the gateway has made a request, it processes the page. This
processing both mangles and processes the MediaWiki API response. The
latter step contains two pieces of related business logic:
1. Deciding if a page has been modified recently.
2. Processing the extract/deciding if it's viable (see processExtract).
In order to support switching between the MediaWiki API and RESTBase and
to simplify the event logging reducer when it comes to instrumenting the
"type" of preview, extract this business logic into a model.

The behavior of the cog varies when:
* The user is logged in/out.
* Page Previews is enabled as a beta feature.
Since the behavior of the cog doesn't vary per-preview, it can be
determined at boot time and passed to the renderer. However, in order to
keep the renderer stateless, we pass the behavior to it when a preview
is added to the DOM.
Changes:
* Add the mw.popups.createPreviewBehavior factory function, which
returns an object that encapsulates how a preview responds to the user
dwelling on it, abandoning it, and clicking on the cog.
* Invoke mw.popups.createPreviewBehavior at boot time and pass it to the
mw.popups.changeListeners.render change listener, which then passes it
to mw.popups.Preview#show.

Per Id1339dc2, the LINK_ABANDON_* and PREVIEW_ABANDON_* actions can (and
should) be merged, as they are always reduced in the same way.
Change-Id: I71b30d4d2774deb4efea9e565f2ccd7383bf08c1
Initially, the link element was added to LINK_ABANDON_* to determine
when an interaction should be reset. However, this wasn't enough to
protect against timing-related bugs, e.g. T154923. Now that tokens are
used to determine when interactions should be reset, the link element
can safely be removed from the LINK_ABANON_* actions.
Supporting changes:
* Update the return type of mw.popups.actions.linkAbandon in its

I2ecf575b introduced a regression where the linkTitleChangeListener
wouldn't destroy the active link's title if it had been dwelled on
within 300 ms of the previous active link being abandoned.
The LINK_ABANDON_END action is dispatched after 300 ms and ignored if
the active link has changed.

... instead of using the active elements, and check also the user
dwelling flag to only act if the user is not dwelling.
Preview and link abandon end and start share now test cases, meaning it
can be collapsed into one action creator in a followup commit.
Change-Id: Id1339dc23e8f1b1b7514c769cd09f8bdadc759b4
When dwelling back to a link, previously a new LINK_DWELL action would
be sent and the reducer would reset the interaction as if it was a new
one.
This shouldn't happen, since dwelling back to the active link (from
the preview, for example) is not a new interaction, and should not
create a new interaction or hide and show the preview.
With this change, the preview reducer has the notion of new or repeat
interactions, and only resets state on new ones, and only sets
isUserDwelling when dwelling on a the link of the current interaction.
Also when the interaction is repeat, we guard on the action creator and
don't trigger the wait or the fetch request.
Change-Id: I71cde81cbfe50b6f955e562e7e5b57d0f920fdb9
... after dwelling on preview.
Currently, the asynchronous PREVIEW_ABANDON_END action wouldn't be
ignored if the user were to have dwelled on the link that the preview is
about. The action is only ignored if the user is dwelling on the
preview, i.e. if preview.isUserDwelling is truthy.
Set preview.isUserDwelling to truthy if the user is dwelling either on
the link or on the preview.

Consider the user repeatedly dwelling on and abandoning a link. Testing
whether or not the element has changed before modifying state is not
sufficient. Fortunately, we already generate a unique token and include
it in the LINK_DWELL action for use in the eventLogging reducer - the
so-called "interaction token".

While I1bf953b2 fixed the typo in FETCH_START_DELAY, it didn't do
anything to address the inconsistency in the time it takes to render a
preview (preview delay).
If the gateway result resolves before the target preview delay (500 ms)
is met, then delay dispatching the FETCH_END action until it is. If,
however, the gateway result resolves after the target preview delay,
then dispatch the FETCH_END action immediately.

* Expose the fetch action to ease testing it and to help tidy up the
mw.popups.actions.linkDwell tests.

previews via their user preferences (see T146889).
Changes:
* mw.popups#createExperiment -> mw.popups#isEnabled
* Make mw.popups#isEnabled act like a factory to maintain backwards
compatibility.

When opening the settings dialog, the form didn't represent the current
enabled status of the application. This change makes sure that every
time the form is shown, the form state represents the current
application state.
If the application is enabled, then the 'simple' (Enabled) option is
selected on the form. If it is disabled then if there's Navigation
popups, it selects 'advanced' (Advanced popups), if there are not, it
selects 'off' (Disabled).
Changes:
* Change listeners
* Set the form state every time the form is going to be shown
* Update tests
* Supporting changes
* Add settingsDialog#setEnabled which updates the DOM form based on the
enabled flag and the navpops state
* Extract isNavPopupsEnabled function in settingsDialog.js to be used in the
form creation and also when setting the form enabled state
* Add test verifying changeListeners#settings shows and sets enabled state
properly when showing the dialog more than one time

Changes:
* Generalized previewCount change listener to syncUserSettings

Change-Id: I403a490fee9c8e125175996ba30c63c232b5598b
The save action has been implemented, and it is listened to by the
canonical enabled state in the previews reducer, and by the settings
reducer to perform UI changes.
The enabled state of the application has been kept in the preview
reducer as the canonical source of truth. See supporting changes for
documentation about the decision.
Actions:
* Introduce new action SETTINGS_CHANGE with the enabled status
* Trigger that action when clicking Save in the settings dialog
Reducers:
* Listen to SETTINGS_CHANGE in the preview reducer to update enabled
status
* On the settings reducer
* Handle the SETTINGS_CHANGE action
* Add showHelp flag to determine if the help should be showing
Change listeners:
* Switch to compare past vs present changes in the implementation
* Handle showing and hiding the help
Supporting changes:
* On the rendered settings dialog:
* Change #hide to actually just hide and remove legacy if statement
* Add #toggleHelp method to show or hide the help dialog
* Add doc/adr/0003-keep-enabled-state-only-in-preview-reducer.md to
support the decision of making the saveSettings action creator return
a Redux.Thunk and keeping the enabled state just in the preview
reducer.
* Add NB to actions#saveSettings explaining and linking to the
document
Follow commits soon:
* Persist the settings change to local storage when it changes, and
unify with the preview change listener

Reducer changes:
* Break the mw.popups.reducers.rootReducer test into @@INIT tests
for each reducer as there's shouldn't be any need to test that a
framework works as documented.
Changes:
* Move the mw.popups.reducers#preview, #eventLogging, and #settings
reducers into their own files in resources/ext.popups/reducers/.
* Make the associated tests mirror the new layout.
* Move the initialization of the mw.popups.reducers namespace into its
own file.
* Remove the mw.popups.rootReducer property in favour of a simple
private factory function per the reducer change above.

Since the user can dwell on a link, abandon it while moving to dwell on
the preview and vice versa:
* The time at which the link/preview was abandoned is recorded and can
be updated.
* The event can only be queued when the link/preview has definitely been
abandoned.
Reducer changes:
* Make the eventLogging reducer:
* Calculate the time it took to show the preview.
* Mark the interaction as finished when the user abandons the link or
the preview.
* Queue a "dismissed" event if the preview hasn't been shown or a
"dwelledButAbandoned" event if it has when the abandon has
finalized.

* Handle the LINK_CLICK action's new shape.
* Start (create) and maintain a model of the user interacting with a
link.

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.

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

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.

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.

with interacting with the User Agent's storage.
* Add ext.popups/experiment.js, which contains the code that that
decides whether or not the user is in the experiment condition.
* Add tests for both units, converting existing tests where appropriate.

Tooltips are intended to be stripped upon `mouseenter` and `focus`
events and then restored during their corresponding `mouseleave` and
`blur` events. This was broken due to duplication of event registration
and no proper deregistration.
Changes:
* Rename `mw.popups.removeTooltips` to `mw.popups.removeTooltip` to
more accurately describe its effect
* Narrow the scope of `mw.popups.removeTooltip`
* Add `mw.popups.restoreTooltip`
* Add `onLinkBlur` to `desktopTarget.js` to handle tooltip restoration
* Update qunit test to reflect changes to functions
* Minor hygiene changes regarding event namespaces

If a user has hovercards disabled, when they right click a link
this will trigger another hover event which will reset dwellStartTime.
This means when a dwelledButAbandoned event fires shortly afterwards
the totalInteractionTime will not be correct.
To remedy this, the calculation of totalInteractionTime and
perceivedWait is moved into ext.popups.schemaPopups
Now that we can trigger events without logging to the server and
checking the total interaction time duration in two places,
let's always run the event and only check it once.
A `hover` event triggers the setting of a dwell start time
A `display` event triggers the setting of the perceivedWait value
* Both are reset on a dwelledButAbandoned.
Since dwellStartTime is controlled inside a single place, getMassageData
no longer needs to clear it.
The test "returns false if dwelledButAbandoned event without a dwellStartTime"
is removed as this should no longer be possible.
Bug: T147846
Change-Id: Ie5917ca86f0d0ab27f4cf507e6dfa2c271433c03
This adds two new events "display" and "hover" which are not
recorded back to the server. The benefits of having these events
is that they are important events in the lifecycle of a hovercard.
This allows us to debug trackSubscribe and ensure we see the behaviour
we expect to see and in a future patchset will allow us to use these
events to drive the calculation of interaction time in one single location
(Sneak preview:

Given we currently have modules defined in extension.json and in hooks
it can be really confusing understanding how the code fits together.
This change hopefully makes this a little clearer by using folder names
that are named after the resource loader modules - this is also consistent
with how we do things in our other extensions.
A images folder is added to the route so that it is clearer that the images
are not used in ResourceLoader module definitions and are only used to illustrate
the beta feature.

The dismiss event is currently a side effect of closing a popup.
This should be more closely coupled with the event that causes it.
This allows the closePopup method to be called without trigging
an event which is a necessary precursor to closing popups when

ext.popups.experiment depends on .core as it initialized the mw.popups
namespace and .core depends on .experiments for
mw.popups#getEnabledState.
By merging the experiment module into core, we can eliminate any
circular dependencies.
Changes:
* Move ext.popups.experiment.js code into ext.popups.core.js
* Remove mw.popups.experiment module and any references to it
Note: ext.popups.experiment.test.js was left in its own file for cleaner
QUnit module setups and easier removal later. I'm not entirely happy
with doing it this way, but I'm not sure changing the mw.config within
the mw.popups.core QUnit module is worth merging the files.

Extract the minimum interaction time of dwelledButAbandoned events to
a unique place: mw.popups.render.DWELL_EVENTS_MIN_INTERACTION_TIME
Lower that interaction time to 0 so that all dwelledButAbandoned events
are logged.

When hovercards are off clicking of a link will log the click
event as many times as you hovered over the link prior to clicking.
To prevent this, stop listening to old events before listening to
new ones.

The schema introduces a new field called `hovercardsSuppressedByGadget`,
which is `true` when the Navigation Popups gadget, rather than the Popups
extensions, is being used to fetch and display article summary.
Note that it may take some time before the Navigation Popups gadget is
loaded onto the page, thus actions taking place before this happens will
record the value of `hovercardsSuppressedByGadget` as `false`. This is
mostly the case with the `pageLoaded` action which almost always happens
before the gadget code is loaded.

These errors do not have any value, they just happen when the user
cancels the current request. Removing these events will result in
less noise for data analysis.

Tested in IE9 and Safari. It seems in Safari the mixture of jQuery
and setAttributeNS causes issues.

Before this change we only used to check whether NavPopups gadget is
enabled once per page load. The premise was that we could figure out
whether the gadget was enabled easily given the module name. Since
the gadget module name can be different on diffirent wikis, that
solution would not scale.
With this change we check whether the gadget is enabled before each
hover over an eligible link. We rely on the existence of the global
`window.pg` object. The existence of the object means that the
gadget is enabled, thus we do not show Hovercards.

This is temporary fix to get Hovercards not to show up when
Navigation Popups gadget is enabled on huwiki. The gadget module is
named 'ext.gadget.latszer' and not 'ext.gadget.Navigation_popups'.
Also check whether the global 'pg' variable is created, which means
the Navigation Popups gadget is enabled.

Unlike what was previously implemented, this patch does not care whether
the user hovers over another link while dismissing the popup.
The `dismissed` action is correctly logged in these cases too.

According to caniuse.com SVG support is available
from IE > 8, Firefox > 3, Safari > 3.1 and Android
> 2.3. Android 3-4.3 does not support masking.
Out of all these browsers, considering market share
and ResourceLoader support, none of these browsers
are of concern to us. In IE8 for example we do not
run JavaScript for our end users. Thus we should remove
this fallback support.
Changes
* Remove createImgThumbnail method and its test
* Groups duplicate CSS groups
* Refactor createThumbnail function
** Leave a FIXME on some curious code

article.surveyLink, article.SIZES and currentRequest do not need to be
globally available on mw.popups.render object. They can be local variables.
Similarly openTimer and closeTimer should not be public APIs.
Changes:
* Add an abort method for purpose of aborting existing requests.

Use the standardised MediaWiki storage system for the simple use
case of disabling/enabling Popups. The jStorage library is 12kb
uncompressed and cannot be justified for this usage (and if it becomes
the standardised library mw.storage will begin using it)
This means that browsers with full localStorage or no localStorage
support will not be able to disable Popups. Given the current ecosystem
of the web - localStorage is widely supported - and the fact that grade
A browsers enjoy localStorage support - this is not a problem.
See https://github.com/wikimedia/mediawiki/blob/REL1_27/resources/src/startup.js#L59
Changes:
* Stop using jStorage
* Cleanup and migrate previous values in jStorage with plan for removing this
in a month.

To avoid sentence parsing bugs in other languages.
We have to artificially remove the always-added ellipsis from textextracts to
mimic previous behavior, and we'll add ellipsis via CSS afterwards.

This action was sent correctly when popups are enabled, but not when
disabled. This commit sends this event also when popups are disabled
so that we are able to compare the metric with popups enabled vs disabled.
Additional changes:
* Chain events in resources/ext.popups.targets/desktopTarget.js
* Add a separate property to the list of defaults and fix formatting.

* Fix invalid rules.
Bug: T135629
Change-Id: I3bfaf137e4d02f0dc809c809edac9b28cb4bdc3a
Changes:
* Disable the desktop target by default
* If the user is in the experiment condition, then enable the desktop
target
* Add PopupsExperiment config var, which, if set to true, causes: the
experiment config to be added to the output as config vars, as well as
the ext.popups.desktop Resource Loader module

As there are an unmanageable amount of synchronous checks of

Breaks EventLogging as the old schema is not compatible with these
new properties. We will reapply the patch later when in a better state.
My bad for merging.
This reverts commit ca20031a0e.
Change-Id: Ia961e0f99339f9045af9d0a4653599a48518cc95
Changes:
* Add the ext.popups.experiment module
* Add the mw.popups.experiment.isUserInCondition function, which
returns a promise that resolves with true if the user is in the
experimental condition, otherwise false
* If the experiment isn't configured, i.e. wgPopupsExperimentConfig is
null or undefined, then the user isn't entered into the experiment,
providing a kill switch
