Since we have feature flagged the new user menu feature, it is
imperative we load both sets of styles until the feature has
shipped. This allows us to switch seamlessly between the two
without worrying about cached HTML being served with updated CSS.
To do this, we add a new class to both user menu's distinguishing
the legacy version from the modern version. The styles are then
scoped to these new selectors.
This also fixes some regressions with the legacy user menu in
modern Vector when wgVectorConsolidateUserLinks is disabled.
Notes:
* No caching selector is needed for #pt-userpage given it can only
ever be output for logged in users.
* ID selectors in general are bad, so scoping to mw-portlet-personal-user-menu-legacy
isolates the legacy component allowing it to be rendered alongside the modern UserMenu

Before this commit the `languageinheader` query param would only take
effect if the A/B test was enabled AND the query param was set. Per
T282543, we want the query param to take effect regardless of the state
of the language/AB test config.
To see new treatment, set `languageinheader=1`.
To see old treatment, set `languageinheader=0`.

* Adds ab test config to enable/disable the ab test. Defaults to `false`
(ab test disabled).
* Adds a `languageinheader` query param which only takes effect when the
ab test is enabled. The query param is cast to a bool and determines
which treatment is shown. For example, set query param to
`languageinheader=1` to see the new treatment. Set query param to
`languageinheader=0` to see the old treatment. To bucket based on the
user's id or global user's id, don't set the query param.
* Moves the language in header config work that was previously in
ServiceWiring into a `LanguageInHeaderTreatmentRequirement` class so
that unit tests can be done on most of the logic that determines whether
the language in header will show.
* Adds logic to bucket user based on [global] user id.

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.

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.

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

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.

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.

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.

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.

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

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.

- Add the Requirement interface and update FeatureManager to work with
implementations of it
- Maintain B/C by constructing an instance of a the SimpleRequirement

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

Add a Vector-specific user preference to Special:Preferences for
toggling skin version, either Legacy Vector or the latest Vector.
The presentation of the new preference section and the default values
for anonymous, new, and existing accounts are configurable via
$wgVectorShowSkinPreferences, $wgVectorDefaultSkinVersion (to be used by
the feature manager in T244481),
$wgVectorDefaultSkinVersionForExistingAccounts, and
$wgVectorDefaultSkinVersionForNewAccounts. These configurations default
to the fullest experience so that third-party configuration is minimal.
See skin.json for details. The configurations are each tested in
VectorHooksTest.php.
When presentation is enabled, the new preference appears as a checkbox;
enabled is Legacy mode and disable is latest. There are a number of
unfortunate details:
- Showing and hiding a checkbox is supported by OOUI. Showing and hiding
a whole section (Vector skin preferences, in this case) is not so this
additional client JavaScript functionality is added in Core (see
Iaf68b238a8ac7a4fb22b9ef5d6c5a3394ee2e377).
- Stylization as a checkbox is wanted. However, the implied storage type
for OOUI checkboxes is a boolean. This is not wanted in the event that
another skin version is added (e.g., '3' or 'alpha'). As a workaround,
the preference is converted from a boolean to a version string ('1' or
'2') on save in Hooks::onPreferencesFormPreSave() and from a version
string to a checkbox enable / disable string ('1' or '0') in
onGetPreferences(). There a number of test cases to help cover these
concerning details.
Documentation for overriding the skin version as a URL query parameter
is provided in anticipation of T244481.

Program upcoming, it's important that we have a shared, intuitive
language to talk about features and their requirements. Centralising
the registration of features and creating an API satisfies does exactly
this.
This change introduces a greatly-reduced version of Piotr Miazga's
(polishdeveloper, pmiazga) original proposed API and associated
scaffolding classes for feature management in Vector, which itself was
based upon his work in MobileFrontend/MinervaNeue. This is done to
establish a foundation upon which we can build the more sophisticated
parts of Piotr's proposal in a piecemeal basis, thereby minimising risk.
Distinct from Piotr's proposed API is the ability to register sets and
features that are always enabled or disabled.
Additionally:
- A Vector.FeatureManager service is registered but not used
- A list of proposed immediate next steps is included
