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.

|
* Retrieve the skin version for the request and compare it with `Constants::SKIN_VERSION_LATEST`.
|
|
* This requirement is met if the two are equal.
|
|
*
|
|
* Skin version is evaluated in the following order:
|
|
*
|
|
* - `useskinversion` URL query parameter override. See `README.md`.
|
|
*
|
|
* - User preference. The `User` object for new and existing accounts are updated by hook according
|
|
* to the `VectorDefaultSkinVersionForNewAccounts` and
|
|
* `VectorDefaultSkinVersionForExistingAccounts` config values. See the `Vector\Hooks` class and
|
|
* `skin.json`.
|
|
*
|
|
* If the skin version is evaluated prior to `User` preference hook invocations, an incorrect
|
|
* version may be returned as only query parameter and site configuration will be known.
|
|
*
|
|
* - Site configuration default. The default is controlled by the `VectorDefaultSkinVersion` config
|
|
* value. This is used for anonymous users and as a fallback configuration. See `skin.json`.
|
|
*
|
|
* This majority of this class is taken from Stephen Niedzielski's `Vector\SkinVersionLookup` class,
