WMDE-Fisch f8562a89d6 svgmin optimizations on updated OOUI icons
Icons were updated in I8feea1b526ff85c4ffdee21ef42c616e72881e76 the
pre-commit svgmin optimizer does these minor changes in the two files.

Pushing these to avoid constantly changed but uncommited SVGs in the 
images directory when working.

Timo Tijhof 81b94eff0a Remove redundant wgPopupsShouldSendModuleToUser variable
It is set based on the same conditional that loads the code,
thus checking it inside the loaded code is a no-op and adds
extra HTML to the <head> that blocks text/layout rendering and
delays fetching of Popups JS.

Thiemo Kreuz 511c74bf72 Make sure to never trigger multiple events
I had to disable ESLint to be allowed to upload this patch. It starts
complaining about something in code I did not even touched. The error
message does not make any sense to me (something about globals being
forbidden in code where I can not spot anything that would be remotely
global).

WMDE-Fisch 0d2d6d4c9b Move getPreviewType form gateway to model
The method itself has not much to do with gateways as such, it's
more about the general preview type selection. Since the preview
types "live" in the model, I thought it might good to move it there.

Doing that the "original" getPreviewType method in the model was renamed
to avoid conflicts. If I get this right, that method is quite specific to
page previews, since it processes the output from the TextExtracts API-
request. - Therefore I also removed the TYPE_REFERENCE there, because this
code path will never be reached with that type afaik.

Inspired by the comments in Id1fa7dad59d8fe80bc60c1e2d7c3fb4087e52d1f and
as preparation for that patch.

Thiemo Kreuz d1c0613186 Fix regression showing page previews on ^ jump mark links
This happened one time before and was fixed via T212419. It now came
back after I2670331, a patch for T214861 that made the title parser
accept more links than before.

This patch implements a decision tree that goes as follows:
1. If it's a link to another page, it can't be anything but a page
   preview, as having a peek into another page is effectively the
   definition of a page preview.
2. Otherwise it's probably a reference preview, but only if:
   * It's a link with a jump mark.
   * The link is actually marked as being a "reference".
   * Reference previews are enabled.
3. If neither of these definitions fit, do nothing. Note this is not
   "hiding errors" we would be able to fix in this code. There are many
   ways to manually arrange wikitext in a way that it looks like one or
   the other, without fulfilling all requirements. Unfortunately the
   user who would see error message or dysfunctional popups would not
   be the same as the user who wrote such wikitext.

See the discussion at I6bd7acc. In this codebase it was decided to not
use "classic" JavaScript, but document it with the benefits TypeScript

upper case JQuery type work.

All the lower-case jQuery this patch happens to touch have been placed
by me, not knowing better at this point.

These are annotations for ESLint as described at:

I tried to move these annotations closer to the line they are about in
case there is only one line. And move it to the top when there is more
than one line using the global.

Thiemo Kreuz bb7ef8f205 Remove unused attributes from .svg files to optimize them further
An id="…" can potentially be used to target elements individually, manipulate
them, or show them in another context. This is done with the elements in the
file pointer-mask.svg. But not with any other image.

The file-rule="…" only has an effect on shapes that intersect with itself.
This is not the case for this basic "L" shape.

If you think this is fine, I might look at the original OOUI icons as well
and apply the same optimizations on them. But there are 800+ of them to be
looked at, and I want to invest the time only if you think it's worth it.

Thiemo Kreuz 9438210889 Teach the title parser to always accept self-links
The definition of "self-link" in this context is an <a href="…">
element that points to the exact same URL as the current document's
location, excluding a possibly different #… fragment. This is typically
the case when the <a> element does not contain a full URL, but something
like href="#fragment". JavaScript's HTMLAnchorElement.href getter
automatically expands this to be a full URL.

Example:
var a = document.createElement( 'A' );
a.href = '#test';
console.log( a.href );

Notes:
* This new code assumes the wgPageName setting properly reflects the
  page name requested via the current document's location. Core does
  give us this guarantee.
* The only URL element that is intentionally not compared is the
  protocol.
* This accidentially fixes T215899 as well, because the namespace check
  is now bypassed for self-links (as it should).

Note: In a previous patch I removed the <?xml …?> line. This conflicts
with what https://www.mediawiki.org/wiki/Manual:Coding_conventions/SVG

because this file will never be shown as an image, and never be shown
standalone. Instead, it will be inserted in the documents DOM. The XML
header doesn't matter anyway then.

Thiemo Kreuz 90acf2a778 Fix pointer mask and CSS offsets for flipped popups
I tested this with all 16 possible combinations:
* The pointer can show up in all 4 corners.
* The popup can contain a thumbnail or not. The code for the pointer
  is very different then, because the SVG masks are only relevant in
  this scenario.
* The thumbnail can be tall or not.
* I even tested tall popups without a thumbnail. This is a combination
  that is impossible in production scenarios.

I found 3 issues. This patch fixes 2 of them:
* The pointer is misplaced in the bottom-right corner when the popup
  does not have a thumbnail (as reported in T215194).
* The pointer is misplaced in the upper-right corner when the popup
  shows a thumbnail.
* The pointer in the upper-right corner is gray instead of white when
  the popup is tall, but does not show a thumbnail. As this is not
  relevant in production, I did not fixed it.

It seems both misplacements are because of the same reason: For some
reason, calculations are done based on the assumption the popup would
be 300px wide, but it is 320px wide.

Note I did not just added 20 everywhere, but manually alligned the
pointer triangles so they are placed exactly the same distance from
the corner as in the three other corners.

Note I did not tested this (yet) in RTL scenarios.

Thiemo Kreuz 5bc4ed8f9f Exclude links in popups to trigger other popups
We discovered a bunch of possible solutions (see previous patch sets),
including replacing the `$( document )` selector with a more specific
one. That idea does not pass the linter.

Very late I realized the original selector starts with
`#mw-content-text`. This heavily limits where popups are allowed to
appear: really only in the main text content area.

We should limit reference popups to the exact same scope.

This fixes the issue described in T215195. Before, the content of the
popup was covered by the selector. Reference links *inside* the popup
would trigger another popup, which makes the current popup disappear.
Now the popup itself is not covered by these event handlers any more.

Thiemo Kreuz fb56a2e729 Mark reference preview content area as "mw-parser-output"
This CSS class is used by the regular wikitext content area, and used
by certain CSS selectors (e.g. the external web link arrow).

The DOM structure for each popup is (intentionally) created outside
of this scope, at the end of the current page's body. This works
great for page previews because the do *not* want to share any styles
with the rest of the page. But reference previews want to do this.

In this patch I also remove the inner <span>. It was misplaced (note
the name) and resulted in block elements nested in an inline element.

Thiemo Kreuz 67ceeaeeed Inline code setting target="_blank" in renderReferencePreview()
As discussed in Iaadcce9. This does have a few benefits:
* Less code in the already pretty big render.js file.
* The code setting the target attribute is much closer to where it
  belongs: in the file that specifies how the content of a reference
  popup should look and behave.
* The class name "mwe-popups-extract" is not mentioned in two different
  files, but in the same.

Note this changes the signature of this src/ui/templates/… file to not
return an HTML string any more, but a jQuery object. The other templates
still return strings. I believe this is fine, and not that much of a
difference anyway. The signatures don't need to be identical. And the
jQuery object still represents the exact same HTML as before.

If it helps we could change all templates/… signatures accordingly.
Could be done in this or a separate patch.

Thiemo Kreuz 03ef969122 Show reference previews only on self-links
This solves the (I believe) only regression we introduced: A bad fake
reference like <span class="reference">[[Other article#Section]]</span>
showed a page preview for the "Other article" before we introduced
reference previews, but would have shown nothing after I9ec57e0.

Checking if the link is a self-link solves this and possibly more related
issues. Only self-links can point to a footnote on the same page.

Manually created fake-references like
<span class="reference">[[#Section]]</span> still have a chance to show
nothing in case the manually created HTML does not strictly follow the
expectations in the gateway. There is not much we can do about this. We
should not accept any arbitrary HTML but need to make at least *some*
assumptions.

Thiemo Kreuz 515775685c Fix a series of issues with misdetected reference elements
This installs a series of safety nets:

* The selector [href*="#"] skips links without a fragment.

* It's still possible that a fragment exists, but is empty.
mwTitle.getFragment() checks this.

* The gateway does not assume the element exists, but checks this first.
If there is no such element, the gateway aborts the request in a way
that no error popup is shown. This is currently only possible with the
`{ textStatus: 'abort', xhr: { readyState: 0 } }` response as seen in
this patch. We might need to introduce a new, more clean way to silently
quit a fetchPreviewForTitle() call.

* The test for the reference gateway finally covers the scraping code.

Thiemo Kreuz a8859658f5 Add missing HTML escaping to all existing page preview types
Including tests for all situations.

I believe it is impossible or extremely hard to actually abuse any of
these places. All these data are not extracted from the current page, but
delivered either by MediaWiki's api.php or a RESTful endpoint, as
configured via $wgPopupsGateway and $wgPopupsRestGatewayEndpoint. A
possible attacker would need to write it's own endpoint (which must either
run on the same server or somehow ignore the CSRF token), and set the
value of mw.config.values.wgPopupsRestGatewayEndpoint on the client to
this endpoint – which requires just *another* attack vector to be able to
do this.

It's "the right thing"(tm) to escape all this anyway.

I found two possibly relevant security reviews of this extension, T88171
and T129177, resolved in 2015 and 2016.

Thiemo Kreuz 0a8f591212 Rewrite title module to preserve all link's #fragments
This will affect all links, including [[Other page#Fragment]] for
example. But it will not have much of an effect there. The mw.Title
class is able to understand strings like "Other page#Fragment". All
old code calls title.getPrefixedDb() on the result. This will *not*
include the fragment. Only the new code will use title.getFragment().

I made sure this does not affect regular page previews, even when the
link is something like [[Other page#Fragment]].

Thiemo Kreuz bb60d5b716 Move default "Footnote" title from gateway to renderer
I guess both is fine: either having the default in the gateway (as it
was before), or in the renderer (as this patch proposes). I, personally,
feel better with having it closer to where it is needed. This way it's
not possible to accidentially deliver a model object with an empty title.
The renderer will catch this.

At the moment we don't know exactly how we will fetch other titles (e.g.
"Book").

This change is split from I15611a4 where it was a little misplaced.

It also includes a test for the default fallback title.

Thiemo Kreuz 46cda9fa44 Add missing escaping for jQuery ID selector
Special characters that have a meaning in one of the many different input
formats jQuery accepts must be escaped.

The real-world use-case are references like <ref name=":1"> with a colon.
But it's many more characters that need escaping. See
http://api.jquery.com/category/selectors/

Note this patch misses a test. I already uploaded I9ec57e0 to fix the
currently incomplete tests. But I can't make it work. How do I create an
element in the test environment so that jQuery finds it?

I suggest to merge this and continue working on the tests later, because
this is currently one of the most annoying issues that makes all testing
unreliable.

Thiemo Kreuz 97a5d335d7 Replace rare {!…} and {?…} JSDoc syntax
This is documented at http://usejsdoc.org/tags-type.html, but not in many
other places, especially not in the JSDuck documentation.

The {!…} syntax means "can not be null". This is the default anyway.

The {?…} syntax means nullable. In a few situation is was used when a
parameter can be undefined. I decided to remove it everywhere and replace
it with {…|null} when appropriate, because this is much more explicit. Less
syntax to remember.

Note I'm intentionally not using the […] syntax when a parameter is followed
by non-optional parameters. Actually skipping a parameter in such a situation
would mess the parameter order up. Having optional parameters not at the end
is sometimes used as a feature in JavaScript code, but not in this codebase,
as far as I can see.

It's not exclusively about page summaries any more.

We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
  generic and don't describe well what the method does. As a reminder:
  It expects a Title object and returns a promise, which returns a
  PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
  return a model object.

So I went for fetchPreviewForTitle. What do you think?

Jan Drewniak 83a28d177f Storybook.js for Popups
Storybook.js provides a framework for
viewing and working with UI components.
https://storybook.js.org/

This patch adds the Storybook.js UI library to Popups for
the purposes of viewing multiple previews at once.
This enables viewing page previews in the following states:

- with thumbnails
- without thumbnails
- with SVG thumbnails
- with narrow thumbnails
- with white background thumbnails
- in RTL languages
- in non-latin languages
- disambiguation popups

Storybook also allows users to change the image or text
of a popup through a GUI.

This patch sets up Storybook as a "mini" repo inside
the.storybook folder with a seperate package.json file
to avoid incompatibilities with the current webpack/babel
(or even Node) versions used in the Popups repo.

Storybook requires at least Node v8.3 to run.
(an .nvmrc file with 11.3.0 has been added to the .stories dir).

To start:
`cd .storybook && npm install && npm run start`.

Nicholas Ray 63031429b8 Upgrade redux / redux-thunk
redux       | 3.6.0 | 4.0.1
redux-thunk | 2.2.0 | 2.3.0

Upgrading these two dependencies caused the build size to increase from
from 12.2 KB to 12.4 KB (gzip) and so the bundlesize was adjusted
accordingly in our package.json.

Additionally, our linters flagged two rules that were then turned off in
.eslintrc.es5.json.

Looks like the changes in Redux were mostly cosmetic with much work
dedicated to typescript definitiions and dropping support of private
imports [1].

The changes to redux-thunk only involved changing typescript typings and
should not affect us. [2]

The upgrade was tested locally and did not appear to break anything.

webpack     | 4.1.1  | 4.27.1
webpack-cli | 2.0.12 | 3.1.2

The upgrade of webpack modified our build files and included these
side effects:

* Our linter flagged the usage of bitwise operators in the build files
so I turned that off in our build file lint config (.eslintrc.es5.json)

* Our build file's size increased slightly from 12.1 KB to 12.13 KB
(gzip) so the package.json's bundlesize was updated accordingly.

No deleterious effects were noticed to popups running locally, but the
jump in webpack version included these notable changes:

* Switch from uglify-es to terser minimizer [1]

[1] https://github.com/webpack/webpack/releases/tag/v4.26.0

The upgrade for webpack-cli was a major version jump, but the params
that we pass to it in our package.json file appear to work as before.

diffs now correctly output errors. This will pick up changes to

--exit-code is passed to ensure that if there are changes then an

The dist folder became out of date as depending on what version
of node you run, the output is different.

To aid debugging, the script that checks the diff now outputs the
node version and the npm version. From now on, we will all have
to use the same node version to build assets.

This is annoying, but we will re-evaluate the approach we are taking

nvm and making consistent use of the same node version.

The assets have been rebuilt with the node version that CI uses.

Nicholas Ray 6a25f70ad5 Use window.devicePixelRatio instead of deprecated jQuery.hidpi
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.

Reduce and optimize SVG markup by
- removing unnecessary `id` attributes,
- lowercasing hex colors following code standard
- merging repeating `fill` attributes in `<g>` elements and

Volker E f47e333ff1 build: Bring SVGO optimization to build step
Enabling SVGO automation with 'grunt-svgmin' and conservative
plugin settings to build step, among those:
- enable removeRasterImages and sortAttrs,
- disable cleanupIDs, removeDesc, removeTitle, & removeViewBox as
  described in
  https://www.mediawiki.org/wiki/Manual:Coding_conventions/SVG#Exemplified_safe_configuration
- disable removeXMLProcInst; if the SVG doesn't start with an XML
  declaration, then it's MIME type will be detected as "text/plain"
  rather than "image/svg+xml" by libmagic and, consequently, MediaWiki's
  CSSMin CSS minifier. libmagic's default database currently requires
  that SVGs contain an XML declaration:
  <https://github.com/threatstack/libmagic/blob/master/magic/Magdir/sgml#L5>.
- make use of pretty and multipass options.

Settings are stored in a JSON file to be independent of the Grunt build
process. Also updating SVG accordingly.

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

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

Changes:
 - 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.
