Nicholas Ray e3abac06a6 Add mw-interlanguage-selector class to language button & hide menu/arrow when appropriate
* We add the `.mw-interlanguage-selector` class to the
.vector-menu-heading in the server rendered HTML. `ext.uls.interface.js`
later attaches a click handler to this selector that loads the rest of
ULS.

* We hide the dropdown arrow for js users and only show it again if
ext.uls.interface module isn't installed or is not being loaded.

* When the `ext.uls.interface` module has been loaded, we hide the checkbox
and checkbox hack menu in favor of showing the ULS popover.

Additionally:

* Adds '.vector-menu-heading' class to menu headings.

* Change h3 selector to `.vector-menu-heading`.

jdlrobson 9f1a1fa829 Simplify menu code
SkinMustache in core provides most of what is required for Vector to
generate its menus.  In the interest of having a canonical source of
truth for menus across all skins, Vector should use this data.

To ensure the HTML generated is (mostly) the same after this patch to
prior, a few modifications are necessary:

* The data from core is decorated so that Vector can continue having its
  own custom class names on menus. This is done using the
  decoratePortletClass method.
* There is no support for a menu having a header representing the
  selected menu item, as is currently the case with variants. This is
  achieved via an extension to getPortletData. It's assumed that later
  when variants are merged with languages, this can be removed.
* Menus are agnostic to how they are displayed, so we must continue to
  add the is-dropdown template variable to drop down menus. In future we
  may want to rethink our Menu partial to make this unnecessary in PHP.
* The portal-first class is redundant in the modern Vector as we can
  use the first-child selector. Previously we introduced a class to
  service the legacy skin where this rule doesn't apply as #p-logo is
  the first child.  However, the legacy skin can do this using a special
  next sibling selector instead.

jdlrobson 89fee04f0b Drop unsupported skin CSS classes
Drop support for vectorMenu, vectorTabs and
vectorMenuCheckbox, body, menu selectors in preference
for standard selectors.

This change will impact a large amount of user scripts/styles but should
not impact any gadgets.

These classes were kept around for user scripts and styles however are not
needed internally. As we transition to a more maintainable skin menu
system, it is time to lose these selectors even though this will cause
disruption.

Vector now will use the mw-portlet class rather than the vector-menu
class in its own CSS styling, however it keeps the other classes to
allow differentiation of the different types of menu.

Changes to test: Previously the tests assumed all portlets were empty
when checking the classes. This is very rare, so its better to check
the classes of non-empty portlets, so several tests are updated
accordingly to drop the emptyPortlet class.

Sam Smith 4449235516 [Special:Preferences] [PHP] Add HTMLSkinVersionField form field
I177dad88 introduced the skin version user preference field and
associated configuration values. Per T242381, the field is to presented
as a checkbox with the implied storage type of a boolean where a string
is needed. A PreferencesFormPreSave hook handler was added to adapt
values of either data type to the other.  While this was a neat solution
to a minor nit, the adapter's implementation is incompatible with the
GlobalPreferences extension as the PreferencesFormPreSave hook isn't run
whilst saving global preferences.

Rather than adding an equivalent hook to the GlobalPreferences
extension, create a custom field based on a checkbox with the adapter
included. This allows us to:

- Separate the business logic concerned with preserving the user's
  VectorSkinVersion preference if they've simply disabled Vector from
  the adapter

- Simplify the adapter's implementation

- Forego adding hooks to the GlobalPreferences codebase

Additional changes:

- Replace repeated string literals with equivalent constants in
  tests/phpunit/integration/VectorHooksTest.php

This hook is run on every page. The SkinTemplateNavigation hook
counter intutively is run only on pages which can exist. I think
it's clearer if we only use SkinTemplateNavigation::Universal hook
and keep the logic for when it runs inside our own code.

Sam Smith b46751d4ed hooks: Don't use SkinVersionLookup directly
The feature manager abstracts away how a feature is enabled from the
consumer of that feature. Accordingly, replace direct instantiation of
SkinVersionLookup with usage of the Vector.FeatureManager service.

Supporting changes:

- Add Vector\VectorServices, a simple wrapper around
  MediaWiki\MediaWikiServices that allows us to both document and
  type-hint services specific to Vector

- Add Vector\Hooks::isSkinVersionLegacy to minimise repetition

Additional changes:

- Make the MakeGlobalVariablesScript hook handler return early if the
  user isn't using the Vector skin like the other hook handlers

jdlrobson ed7fd252cd Refactor: Replace PHP complexity with JS simplicity
In PHP we add collapsible classes to all elements except watchstar
so that certain tabs can be collapsed under the more menu in JS.
This adds unnecessary complexity to our codebase and is not used
if JS is disabled.

To simplify this and bring Vector's PHP consistency with core this
logic is moved to JavaScript.

jdlrobson ee6974ad35 Merge SkinVector and VectorTemplate (step 1/2)
Please note I7e06a4cc226f3434c0f655212a464b8b98bcc7f4 should be
merged at the same time as this patch.

== The background ==
All extensions have been weaned of BaseTemplate hooks in
Wikimedia projects.

This change now means that Vector will no longer run
any BaseTemplate hooks. See the epic T253809 for the
implementation details.

== The change ==
BaseTemplate will now have nothing to do with the rendering of
Vector. The skin version is added to express the significance of
breaking compatibility with 3rd party extensions.

We TEMPORARILY remove SkinVector to retain git blame. SkinTemplateVector will
be renamed SkinVector in the follow up (see 2/2)
Update skin.json to use SkinTemplateVector for the skin (this will be fixed
in a follow up).

The isLegacy method is moved to SkinTemplateVector.

Changes of note:
* html-debuglog is no longer needed. SkinMustache includes this information on
the skins behalf
* html-printtail and html-headelement are now not needed in the master template
and added by SkinMustache
* Skin::getAfterPortlet does not provide the `after-portlet` wrapping element provided
by BaseTemplate::getAfterPortlet so this is added
* SkinTemplate::getFooterIcons does not support the options that BaseTemplate::getFooterIcons
does so any icons which do not have an image must be manually checked for and unset

Known changes to HTML output as a result of intentionally
delegating their output to the core SkinMustache class:
* A new line is removed between the body element and #mw-page-base
* #mw-html-debug-log now appears at the end of the body element
* #printfooter is now a child of #mw-content-text rather than sibling.

jdlrobson e048c2a729 Refactor: Simplify and standardize menu definitions
* Standardise the menu markup. This means all menus in Vector will now
be wrapped in a div and will have a heading.
* All menus now have the vector-menu class. Styles specific to personal tools
are moved to layout since these are concerned with placement.
* The ul class will always have menu class.
* emptyPortal class is generalised into vector-menu-empty for consistency
with other classes and moved from common.less into Menu.less
* Standardise hooks - BaseTemplateAfterPortlet can now be run on any
menu.

Changes to HTML:
* lang and dir attributes are moved from the h3 up to the div element
.vectorTabs, .portal(s) and #p-personal now has hidden span element inside h3
* for non portals ul.menu" is now wrapped in a div.vector-menu-content

This change does impact the following CSS selectors which will need to be updated:

I see no matches for these selectors in code search.

```
 #p-variants > ul
 #p-namespaces > ul
 #p-personal > ul
 #p-views > ul
 #p-cactions > ul

```
Using global-search.toolforge.org I see one match
for p-variants, 26 for p-namespaces, 30 for p-personal,
36 for p-views and 7 for p-cactions. I see this as acceptable
breakage provided a user notice is sent out which it has been

An old code path supporting portals outputted by hooks with
strings is marked as deprecated to simplify this code in future.

array-portals-first -> data-portals-first (the value is not
an array)

Changes:
* $this->getLanguages and  $this->getToolbox() always returns an array (see BaseTemplate)
but we previously supported portals made using raw HTML. Let's move away from that
behaviour and deprecate it.
* Hooks are moved into buildSidebarProps and marked as deprecated where possible
(SkinTemplateToolboxEnd). SidebarBeforeOutput can be used instead.

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.

@polishdeveloper / @pmiazga in

Stephen Niedzielski 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.

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.

Sam Smith 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
