* Added a server requirement for the php-intl extension (shipped by default with most PHP distributions)
|
||||
* Replaced Zend_Date and Zend_Locale with the php-intl extension.
|
||||
* Consistently use CLDR date formats (rather than a mix of CLDR and date() formats)
|
||||
* Moved config into a new module: [silverstripe/config](https://github.com/silverstripe/silverstripe-config/).
|
||||
See upgrading notes below.
|
||||
* Falsey config values (null, 0, false, etc) can now replace non-falsey values.
|
||||
* Introduced new ModuleLoader manifest, which allows modules to be found via composer name.
|
||||
E.g. `$cms = ModuleLoader::instance()->getManifest()->getModule('silverstripe/cms')`

/**
|
||||
* The configuration system works like this:
|
||||
*
|
||||
* Each class has a set of named properties
|
||||
*
|
||||
* Each named property can contain either
|
||||
*
|
||||
* - An array
|
||||
* - A non-array value
|
||||
*
|
||||
* If the value is an array, each value in the array may also be one of those
|
||||
* three types.
|
||||
*
|
||||
* A property can have a value specified in multiple locations, each of which
|
||||
* have a hard coded or explicit priority. We combine all these values together
|
||||
* into a "composite" value using rules that depend on the priority order of
|
||||
* the locations to give the final value, using these rules:
|
||||
*
|
||||
* - If the value is an array, each array is added to the _beginning_ of the
|
||||
* composite array in ascending priority order. If a higher priority item has
|
||||
* a non-integer key which is the same as a lower priority item, the value of
|
||||
* those items is merged using these same rules, and the result of the merge
|
||||
* is located in the same location the higher priority item would be if there
|
||||
* was no key clash. Other than in this key-clash situation, within the
|
||||
* particular array, order is preserved.
|
||||
*
|
||||
* - If the value is not an array, the highest priority value is used without
|
||||
* any attempt to merge.
|
||||
*
|
||||
* It is an error to have mixed types of the same named property in different
|
||||
* locations (but an error will not necessarily be raised due to optimizations
|
||||
* in the lookup code).
|
||||
*
|
||||
* The exception to this is "false-ish" values - empty arrays, empty strings,
|
||||
* etc. When merging a non-false-ish value with a false-ish value, the result
|
||||
* will be the non-false-ish value regardless of priority. When merging two
|
||||
* false-ish values the result will be the higher priority false-ish value.
|
||||
*
|
||||
* The locations that configuration values are taken from in highest -> lowest
|
||||
* priority order.
|
||||
*
|
||||
* - Any values set via a call to Config#update.
|
||||
*
|
||||
* - The configuration values taken from the YAML files in _config directories
|
||||
* (internally sorted in before / after order, where the item that is latest
|
||||
* is highest priority).
|
||||
*
|
||||
* - Any static set on an "additional static source" class (such as an
|
||||
* extension) named the same as the name of the property.
|
||||
*
|
||||
* - Any static set on the class named the same as the name of the property.
|
||||
*
|
||||
* - The composite configuration value of the parent class of this class.
|
||||
*
|
||||
* At some of these levels you can also set masks. These remove values from the
|
||||
* composite value at their priority point rather than add. They are much
|
||||
* simpler. They consist of a list of key / value pairs. When applied against
|
||||
* the current composite value:
|
||||
*
|
||||
* - If the composite value is a sequential array, any member of that array
|
||||
* that matches any value in the mask is removed.
|
||||
*
|
||||
* - If the composite value is an associative array, any member of that array
|
||||
* that matches both the key and value of any pair in the mask is removed.
|
||||
*
|
||||
* - If the composite value is not an array, if that value matches any value
|
||||
* in the mask it is removed.
