Allow extensions to register new types of previews via
extension attributes.
Changes:
- The check for reference previews doesn't make sense
as $('a[ href*="#" ]' ) will match any elements with a hash
fragment, so the additional check to Title.getFragment
will not provide a different result. This was introduced in
I9ec57e0fbb0d21beaaa7b359c1c2bef64d2c14f5
- Links that point to themselves are marked with mw-selflink
in MediaWiki so this can use the not selector we already have.
- The new API is used internally and only available via extension
Attributes
- An example is provided in SkinJSON
(https://github.com/jdlrobson/mediawiki-skins-skinjson/pull/14)

This was done while working on T277639 where we introduced
multiple "enabled" flags for individual popup types. This
change listener is one of very few places that work with
this flag. This patch is meant to make this code more robust
and easier to change.
A few unrelated but trivial changes are included that make
code shorter and hopefully easier to read.
Also fixes a bug with tooltips overlapping previews.

Provide containers for page previews examples
In storybook we avoid position absolute but this deviation from
how they behave in reality could lead to subtle differences that impact
the rendering of previews. It also doesn't allow to see the preview
in the context of the link which is an important part of visually
verifying the position of the pokey arrow.
This also allows us to rethink the broken RTL mode. We now scope
LTR rules to a LTR class that is present on the container, and use
the CSSJanus parsed stylesheet for RTL.

The requirement for landscape images is to be at least 320px
wide. The requirement for portrait images is more relaxed,
only 250px high. Images that fall between these two
requirements currently don't show a thumbnail, even if they
could.
This change affects a very specific group of images:
* Square images from 250 x 250 to 319 x 319.
* Landscape images from 251 x 250 to 319 x 250.
* Landscape images from 319 x 250 to 319 x 318.
The most extreme ratio is 319 x 250. This will be cut to
203 x 250. I.e. the absolute extreme are 58px missing left
and right, but never more.
Requested at https://www.mediawiki.org/wiki/Topic:Vwl97pm6as9fuf6k
Additional stories for testing more extreme small images:
* Small Tall - 300x1000px
* Small Short - 300x200px
Update tests accordingly.

This is not really an error. It does not really have
consequences for the user, except:
* It might waste bandwidth because the module is loaded, but
unused.
* It might waste a tiny bit of CPU time.
However, this can only happen for registered users, and only
with very specific combinations of settings (notably: a
conflicting gadget must be activated).
The reason it's marked as an error is that previously we could
give more guarantees about this. This changed recently. We will
check if the log message is still helpful and either remove it,
or restore the previous guarantees.

We added reference preview as a checkbox the the
anonymous user settings. To handle both popup types
(pages and references), we changed the usage of
preview.enabled. We pass on all types as a map
inside preview.enabled. The footer link to edit the
settings will appear for anonymous users if at least
one type is disabled.
Bug: T277639
Change-Id: I860a1b35ac7749d8d0884575f6acb7186ad8e4d0
We still have 2 different mechanisms in place, maybe even 3:
* We simplify the CSS selector when we know a popup type is
disabled, and it's impossible an anonymous user can enable it
at run-time.
* We create that "initiallyEnabled" map that allows anonymous
users to toggle the individual popup types at run-time.
* This map is also used to check if the footer link should be
shown.
* There is also a wgPopupsReferencePreviews global that acts as
a "kill switch". However, this is not a pure feature flag,
but incorporates the user setting for registered users. This
is currently partly redundant (checking
`mw.user.options.get( 'popupsreferencepreviews' )` does the
same) and can be removed later when the feature flag is not
needed any more.
The footer link currently acts odd because anonymous users are
unable to enable ReferencePreviews, but get the footer link.
This patch introduces a 3-state model:
* `true` acts as before.
* `false` means a popup type is disabled, but anonymous users
can enable it (i.e. this is the opt-out behavior for anonymous
users).
* `null` means a popup type is not available at run-time, for
nobody. Anonymous users can't do anything about this.
Registered users must leave the page and change a setting.
Bug: T277640
Change-Id: Id8d1396c09cf0f706034a66f9cd3c880a8b33df8
An "advanced" option was first introduced in 2014 via patch I374805e
(originally named "monitor-or-edit", renamed via patch I7b4f6d2).
The isNavPopupsEnabled() function was added in 2016 via patch
Ic660f48.
The code that disables the extension entirely the moment the NavPopups
gadget is enabled was added in 2017 via patch Ia474b1b (T151058) and
patch Ia837816 (T160081).
As of now, the "advanced" option can only be seen in an extreme edge
case:
* Only for anonymous users.
* Only if NavPopups is enabled by default for anonymous users.
* Only if the $wgPopupsConflictingNavPopupsGadgetName setting is
misconfigured.
* … or if NavPopups is not a gadget in the first place, but e.g.
loaded via Common.js.
In this situation the settings dialog opens with all *3* options. This
is broken for several reasons:
* The "simple" option enables the extension, but doesn't disable
NavPopups. Both trigger, resulting in both popups being displayed
the same time.
* Since "simple" is the default, this bogus behavior is the default
for anonymous users.
* The "off" option doesn't stick. Every time the settings dialog opens
"advanced" is checked instead.
* "Off" can't work anyway. There is no code to disable the gadget.
* Only the "advanced" option "works", but more by accident.
It's unclear how to fix this:
* There is no code that does anything with the "advanced" option. It's
not even stored. The behavior of the option is identical to "off".
* The code appears as if "advanced" was meant to be shown instead of
"off". I.e. anonymous users can only choose one of the popups, but
not disable both. But there is no code to hide the "off" option.
* The bug when both popups are displayed was fixed in 2017 via an
entirely different mechanism. Re-introducing "advanced" does not
only mean duplication, it's unclear how the 2 mechanisms are meant
to work together.
It really, really feels like this was just forgotten.

This patch does nothing but rename a pair of variables:
"prevState/state" becomes "oldState/newState". Reasoning:
1. The abbreviated "prev" is confusing, especially because we
are in a codebase that is all about "previews".
2. We are in a context that is all about a state **change**.
Change listeners get notified about the change from one state
to another. While it would be possible to stick to the already
mentioned "previous/current" terminology, I find the word
"current" confusing. What is "current" in this context? Did
the state already change? Am I notified about a change that is
**going** to happen or already happened? Is this even relevant?
I don't think it is. Therefor "old/new".
Another possibility is "previous/next".
Change-Id: Id886e1a095967fe86fb9021f59e335c62da8994e
The nextState() function was not able to understand updates that
are deeper than a single level. Example:
nextState( state, { pagePreviews: { enabled: true } } )
Before, this would replace whatever was in the "pagePreviews"
property with { enabled: true }, but not merge it. In some places
a single level of recursion was done manually because of this.
This can be removed now.
This is done in preparation for splitting the "enabled" flag into
separate ones for each popup type.

Note how getIsEnabled() is documented: "if the user hasn't
previously enabled or disabled Page Previews […] then they
are treated as if they have enabled them."
In other words: The idea that the default should be true is
encoded twice in this code. This is just not necessary. We can
remove one without loosing anything.
Motivtion: Simplifying the code and reducing the package size.
Since the code fundamentally depends on this default value
anyway, we can clear the users localStorage when they decide
to go back to the default – instead of storing a "1" which
does the same as the default.

It turns out the TextExtracts extension is build in a way so
that the parameter plaintext=1 alone is not enough. It does
not really mean "please return plain text" but "please don't
return HTML". It can still return one of three formats:
* Wikitext.
* An intermediate parser format where headlines are not
`== this ==` but `��2��this`.
* Actual flat plain text.
The default is wikitext. That's why we see `== wikitext
syntax ==` in certain edge-case situations. Forcing it to
"plain" fixes this.

(I9a73b3086fc8fb0edd897a347b5497d5362e20ef):
- Don't make wait#wait() abortable. This adds complexity and isn't
needed since the token is rechecked in the .then() of
actions#linkDwell(). The request is permitted to continue and fetch if
that token still matches and is never issued otherwise.
Once a request has been issued, that request is still abortable.
However, note that calling XHR.abort() is just a request to abort and
may not be granted. Whether or not XHR.catch() is invoked is what
dispatches the FETCH_ABORTED action (or doesn't if the request to
abort was denied).
- Remove the abort tests for wait#wait() since the functionality is no
longer provided.
- Pass the preview token in the FETCH_ABORTED action and reduce
FETCH_ABORTED the same way as ABANDON_COMPLETE in reducers/preview.
The follow-up patch, I3597b8025f7a12db0cf5d83cce5a77abace9bae3, adds
integration tests for the specific bug fix. Note that these Selenium
tests are incompatible with the content proxy, so it is probably best to
simply unset $wgPopupsRestGatewayEndpoint and $wgPopupsGateway and allow
the defaults to be used. Also note that the tests are incompatible with
recent versions of Node.js (so use NVM) and emit many deprecation
warnings (so set deprecationWarnings to false in
tests/selenium/wdio.conf.js) An example run of the tests looks something
like:
chromedriver --url-base=wd/hub --port=4444 &
# If any changes are made locally, also run `npm -s start &`.
MW_SERVER=http://localhost:8181 \
MEDIAWIKI_USER=foo \
MEDIAWIKI_PASSWORD=bar \
DISPLAY= \
npm -s run selenium-test
Live testing may be performed as well. Remember that RESTBase requests
are incompatible with MobileFrontend's content proxy hack so ensure to
comment it out if $wgPopupsGateway is configured for RESTBase (see
T218159).
1. Open the DevTools network tab.
2. Disable the browser cache. Chromium, at least, won't abort requests
coming form the cache.
3. Hover back and forth quickly over a preview. In Chromium, canceled
requests are labeled and appear red. This is a good scenario to test.
With the patch, a preview should always be shown when ultimately
resting on a link. Without the patch, it is possible to rest upon the
link with no preview showing. This may require several attempts.

As mentioned in T205744, EventLogging schema ResourceLoader modules have
been deprecated. This removes those modules from loader calls.

Removing wrong ARIA `role=tooltip`. Those are meant only for static
text content on short `title` like dynamic tooltips.

We did a strict === comparison before. This works fine when the page
zoom is either 100% or 200%. Other zoom factors produce fractional
numbers. Comparing them with === is doomed to fail because these numbers
are IEEE representations, not necessarily being identical in situations
where you would expect them to be identical.
This applies two fixes: Change the comparison to a >=, and always ignore
1 extra pixel. If we are so close to the bottom, the gradient is not
helpful any more.

This fixes page previews appearing when there is self link to a page
that has a file extension in it's name.

This is relevant in case the HTML looks like this:
<… class="reference"><a><span>[</span>2<span>]</span></a></…>
The additional <span> cause many additional mouseover and mouseout
events. The code already tries to filter these duplicate events that
are all triggered on the same link, but gets confused, especially when
the multiple chains of events overlap each other in unexpected ways.
It's a timing issue. This change does not fix the fundamental issue,
but does make it much less painfull.
This patch also removes the > from the selector. This is in case the
HTML looks like this:
<… class="reference"><span><a>[2]</a></span></…>
The additional inner <span> would prevent any reference preview from
being shown.

Introducing the REFERENCE_CLICK action that will fetch and show the
preview for the clicked reference right away without any delay.
The main goal of the new chain of events introduced with the reference
click is showing the reference preview right away. The actions triggered
by the dwelling include delays in multiple parts of the process.
If there's a dwell action-chain in progress when the click action is
executed, the related promise ( that might still include steps with
delays ) and the reference preview is retrieved and shown right away
re-using the token.
In the case where there's no dwell action running ( e.g. when the click
was triggered via touch ) we create a new token and start from scratch.
In either case we want to avoid, that multiple clicks trigger multiple
actions and abort early when there's already a click action in progress.
