6a9ee465bc [modern] A new version of Vector with a new logo
Changes to support feature:
* ResourceLoaderSkinModule logo features are dropped
* New layout provided given the fork in layout between legacy and new.
* Legacy sidebar styles now pulled out
* breakpoint styles are not carried over from legacy Vector
The new Vector layout for now has one breakpoint.

Changes to storybook:
* The storybook script now pulls down image assets so that the logos can
be shown in storybook. The script is adjusted to make use of a static folder to
serve these images.

Note:
* The legacy mode is not touched as part of this patchset.
* The personal menu is unaffected by this patch and is out of scope.
* The alignment issue is noted, but will be solved at a later date.
* Changes to portal are out of scope.
* Adding storybook for modern descoped, given its not possible to load
both legacy layout and modern layout inside a storybook at current time.

Sample config:

$wgLogos = [
        'icon' => 'https://di-logo-sandbox.firebaseapp.com/img/globe.png',
        'tagline' => [
                'src' => 'https://di-logo-sandbox.firebaseapp.com/img/tagline/en-tagline-117-13.svg',
                'width' => 117,
                'height' => 13,
        ],
        '1x' => 'https://en.wikipedia.org/static/images/project-logos/enwiki.png',
        'wordmark' => [
                'src' => 'https://en.wikipedia.org/static/images/mobile/copyright/wikipedia-wordmark-en.svg',
                'width' => 116,
                'height' => 18,
        ],
];

ec6307e669 Merge "[fix] "Existing account only" skin version config" 2020-04-29 18:55:30 +00:00
Stephen Niedzielski
709772fa12 [fix] "Existing account only" skin version config
de76ab5 added the config,
`$wgVectorDefaultSkinVersionForExistingAccounts`. Its usage in
`Hooks::onUserGetDefaultOptions()` was invoked not only for existing
accounts but anonymous users _as well._  This is a bug, due to my own
misconceptions about the hook, that went against both the config's name
and its documentation.

Unfortunately, user sessions are unavailable in
`Hooks::onUserGetDefaultOptions()` so it does not seem to be possible to
determine whether the active user is an anonymous or existing account.
This patch drops the hook and centralizes all version determination
logic in SkinVersionLookup::getVersion(). SkinVersionLookup requires a
the active User object and can make the anonymous / existing account
determination by checking login state.

The issued was identified while responding to review feedback given by
@polishdeveloper / @pmiazga in
I52d80942b4270c008d4e45050589ed9220255a50.

cee5ee0003 Make legacy mode a feature
Changes:

- Add the LatestSkinVersionRequirement requirement class, which lazily
  evaluates the application state to get the version of the skin for the
  request.

  This majority of this class is taken from Stephen Niedzielski's
  Vector\SkinVersionLookup class, which was introduced in d1072d0fdf.

- Register an instance of LatestSkinVersionRequirement and register the
  'LatestSkin' feature that requires that requirement

- Re-introduce SkinVector::isLegacy and make it defer to the Feature
  Manager

703903daac [legacy] Split sidebar code and mark layout as legacy in preparation for new layout
Going into the new version of Vector, we'll want to rewrite the layout
rules entirely and decouple the sidebar from the logo.

To prepare for this we will move the layout file into a legacy folder.
We also separate Sidebar styles needed for the legacy mode from the old mode.

This will allow us to make changes to the header in new Vector without having to touch
or test the legacy codebase via a new file layout.less and using the existing sidebar
code.

In new Vector, the logo will no longer be present, so we need a more
future proof way of determining what the first portal is.

A new class `portal-first` is added (no decision about adopting BEM
has been made yet).
Cached pages will continue to use the old selector for now.

63ee9450b7 Refactor: Standardize menu data (DRY!)
VectorTemplate has various functions that repeat themselves, only
differing in their choice of names.

This refactor begins by focusing on the personal menu and introducing
a generic getMenuData function. Hardcoded `p-personal` is replaced with
an `id` template key and `msg-label` is renamed `label`.

Future patches will simplify VectorTemplate by using this new
function.

You'll note the resulting PersonalMenu.mustache file is identical
to VectorTabs. These will be merged in I098e6921e8f7ef65dacacf09b9c25f70c945e58e

d1072d0fdf [dev] add skin version query parameter override
As described in the readme but not implemented until now, this patch
enables the skin version to be specified as a URL query parameter. This
is useful for testing both skin versions during development and on wiki,
as well as enabling sharing URLs with a specific skin (Vector) and skin
version (1 or 2).

Obtaining the actual skin version requires tying together three input
sources, WebRequest, User, and Config. It seems simple but it'd be easy
to botch. For this reason, a helper class to correctly interrogate them
and tests are provided.

872519ab94 Drop the Navigation component
It is not the most useful of components and adds an additional layer
of complexity similar to multiple inheritance chains that we find in
Object oriented programming.

I suggest we use index.mustache going forward for laying out the different
components and use components/template partials for reusable components.

d2b19192c7 Merge "Add opt-out link to Sidebar for Vector/Logged-in Users Without Abstractions" 2020-03-27 00:36:29 +00:00
Nicholas Ray
ec382a8c86 Add opt-out link to Sidebar for Vector/Logged-in Users Without Abstractions
This commit is singularly focused on adding a link to the sidebar for
Vector, logged-in users. It does the bare minimum to fulfill the
requirements of T243281.

Additionally, it will help to answer the question "Do we need to use
abstractions (other than maybe different templates) to separate Legacy
Vector from Vector" by intentionally leaving out any abstractions in
order to make it easier to compare with a follow-up patch
(Ib2ef15180df73360cc1de25b893e49d415d23e1a) which does use abstractions.

It is a good thing to question whether or not we need addtional
abstractions in VectorTemplate and if they will help us as unnecessary
abstractions can have the opposite effect and just lead to further
frustrations down the road.

Therefore, I urge you, the reviewer, to let me know your thoughts! If
abstractions are viewed as not making our lives any easier, the
follow-up patches may be completely discarded and that's totally okay
with me. :) I think it's a good think to talk about now though.

Important changes:

* The VectorTemplate constructor was changed to allow injecting the
config, templateParser, and isLegacy boolean (only the config was
allowed before this commit). According to MediaWiki's Stable Interface
Policy, "Constructor signatures are generally considered unstable unless
explicitly declared stable for calling" [3]. Given that VecorTemplate's
constructor is not marked as stable, it is justified to do this without
warning according to the policy.

* Due to the above, the 'setTemplate' method is no longer needed and was
marked as deprecated.

* VectorTemplateTest was made to adapt to the new VectorTemplate
constructor. Additionally, it now extends from
MediaWikiIntegrationTestCase which my intelliphense server can pick up.
I *think* MediaWikiTestCase is just an alias to
MediaWikiIntegrationTestCase [1] and MediaWikiTestCase file was renamed
to MediaWikiIntegrationTestCase in [2], but I'm willing to change it
back if there is pushback to this.

Open questions:

* What are VectorTemplate's responsibilities? To me, it acts right now
as a controller (because it echos the full HTML string from the
template), a model (because SkinTemplate::prepareQuickTemplate sets data
on it which it later retrieves through `$this->get()`), a presenter
(because it adds data tailored for a web-centric view), and a view
(because it renders HTML strings instead of letting the view/template be
solely responsible for that). Arguably, some business logic might be
mixed in there as well (because it checks to see if a User is logged
in/has necessary permissions to show x which my changes here add to).
This might not be a problem if we keep VectorTemplate relatively small,
but will it remain this way as we progress further in Desktop
Improvements?

* How do we write tests for VectorTemplate without exposing unnecessary
public methods? For example, if I want to test the `getSkinData()`
method to see what state will be sent to the template, how should I do
this? One option might be to use `TestingAccessWrapper` to expose these
private methods which is what
`VectorTemplateTest::testbuildViewsProps()` does. Another option is to
accept this method as public. Is there a better way? Keep in mind that
even with access to this method, there might be many things to mock.

84226b41b6 featureManager: Add DynamicConfigRequirement requirement
We expect the vast majority of requirements and features to be defined
in services as possible. However, there are some "complex" requirements
that require additional application/HTTP request state. Unfortunately,
service wiring is done before some of that state is available.

I65702426 attempted to work around this by requiring clients of the
Feature Manager to pass that additional state on every interaction with
the system. Those complex requirements would then select the parts of
the state that they required when it was required. However
implementations of \IContextSource are God objects and their use should
be limited.

Whilst reviewing I65702426, Stephen Niedzielski mentioned that the
application state being available is a requirement. This remarkably
simple solution:

- Keeps the Requirement interface and FeatureManager API free of God
  objects;

- Is true to the nature of the Feature Manager - it makes clear and
  centralizes the various checks for application state being available
  across the codebase; and

- Inject a Requirement implementations' dependencies at construction
  time

It just so happens that the $wgFullyInitialised variable flags whether
the application state is available...

Changes:

- Add the the FeatureManager\Requirements\DynamicConfigRequirement class
  and tests. The DynamicConfigRequirement lazily evaluates a single
  configuration value whenever ::isMet is invoked

- Register an DynamicConfigRequirement instance, configured to evaluate
  $wgFullyInitialised while constructing the Vector.FeatureManager
  service

To have a clean break for upcoming changes we will duplicate

The preferred name however does come with some caching challenges.
Cached HTML served to anons will continue to load the style module
`skins.vector.styles` for a period of 1-4 weeks

Provided we are careful with our changes during this period this
should be okay.

d14caf2f11 featureManager: Add Requirement interface
FeatureManager::registerRequirement established the interface for a
requirement: its name and whether it's met.

However, the Feature Manager also needs to handle scenarios where a
requirement needs additional context before it can be considered met.
That context may not be available when the application is booting, e.g.
checking if the user is logged in; or the logic is complicated enough
that it should be under test.

Changes:

- Add the Requirement interface and update FeatureManager to work with
  implementations of it

- Maintain B/C by constructing an instance of a the SimpleRequirement
  DTO

64bd4601b4 featureManager: Add typehints
I735fd640 bumped the required MediaWiki version to 1.31. That version
dropped support for PHP 5.x.

Wherever possible, update FeatureManager's methods to use PHP 7.0.x's
scalar and return type declarations.

406012f863 docs: Improve VectorTemplate Mustache param docs
Separate value type from value groups, to clarify that e.g.
something coming from a hook does not mean it should not have "html-".

3f95820467 featureManager: Set -> Requirement
As was noted in https://phabricator.wikimedia.org/T244481#5859513, the
term "set" doesn't seem natural. Piotr Miazga (polishdeveloper, pmiazga)
and Nicholas Ray (nray) suggested a number of good replacements,
including "requirement." Serendipitously, this term is already used in
FeatureManager's documentation.

cdd5ebd74d Use template partials rather than HTML strings
CHANGES to  index.mustache:
Changes can be understood by looking at the diff of
the file stories/skin.stories.js

The additional changes in stories folder export the data passed to
those templates. A new file is used as exporting any variable in a
file suffixed stories.js will be assumed to be a story entry.

The changes to index.mustache are as follows:
* html-footer is replaced with data-footer and Footer
component is rendered via template partial
* html-navigation is replaced with data-navigation and
Navigation component is rendered via template partial

CHANGES to Navigation.mustache:
Changes are best explained by looking at the diff to
stories/navigation.stories.js
and navigation.stories.data.js
* html-personal-menu is replaced with data-personal-menu

0ba99a1e97 Make sure Vector skin preferences always follows skin
Sections can be nested. Using rendering/skin as the parent
means that Vector's skin preference will always come straight
after the skin preference and before Popups.

A change in core is needed to update the selector for the element which
shows/hides the subsection as well as provide a generic message key to
replace the one inside this repository.

Note: If the "Vector" specific heading is needed, we can achieve this
with a little more work but that is a conversation for another time.
