/**
|
|
* Some application state changes throughout the lifetime of the application, e.g. `wgSitename` or
|
|
* `wgFullyInitialised`, which signals whether the application boot process has finished and
|
|
* critical resources like database connections are available.
|
|
*
|
|
* The `DynamicStateRequirement` allows us to define requirements that lazily evaluate the
|
|
* application state statically, e.g.
|
|
*
|
|
* ```lang=php
|
|
* $featureManager->registerComplexRequirement(
|
|
* new DynamicConfigRequirement(
|
|
* $config,
|
|
* 'Sitename',
|
|
* 'Foo'
|
|
* )
|
|
* );
|
|
* ```
|
|
*
|
|
* registers a requirement that will evaluate to true only when `mediawiki/includes/Setup.php` has
|
|
* finished executing (after all service wiring has executed). I.e., every call to
|
|
* `Requirement->isMet()` reinterrogates the Config object for the current state and returns it.
|
|
* Contrast to
|
|
*
|
|
* ```lang=php
|
|
* $featureManager->registerRequirement(
|
|
* 'Foo',
|
|
* $config->get( 'Sitename' )
|
|
* );
|
|
* ```
|
|
*
|
|
* wherein state is evaluated only once at registration time and permanently cached.
|
|
*
|
|
* NOTE: This API hasn't settled. It may change at any time without warning. Please don't bind to
|
|
* it unless you absolutely need to
