In rare cases it is still possible to access the request of the current controller via
`Controller::curr()->getRequest()` to gain access to the current session.
#### Upgrade extensions to work as singletons
In SilverStripe 4.0 extensions are now all singletons, meaning that state stored as protected vars
within extensions are now shared across all object instances that use this extension.
As a result, you must take care that all protected vars are either refactored to be stored against
the owner object, or are keyed in a fashion distinct to the parent.
E.g.
```diff
class MyExtension extends Extension {
public function getContent() {
- if (!$this->contentCache) {
- $this->contentCache = $this->generateContent();
- }
- return $this->contentCache;
+ $contentCache = $this->owner->getField('contentCache');
+ if (!$contentCache) {
+ $contentCache = $this->generateContent();
+ $this->owner->setField('contentCache', $contentCache);
+ }
+ return $contentCache;
}
}
```
In addition when using extensions with distinct constructor arguments it's advisable to
use `yml` to register those constructor arguments and use a service name or alias in
`private static $extensions`.
E.g. This is the service definition for the various versioned extension variants
```yaml
---
Name: versionedextension
---
SilverStripe\Core\Injector\Injector:
# Versioning only
SilverStripe\Versioned\Versioned.versioned:
class: SilverStripe\Versioned\Versioned
constructor:
mode: Versioned
# Staging and Versioning
SilverStripe\Versioned\Versioned.stagedversioned:
class: SilverStripe\Versioned\Versioned
constructor:
mode: StagedVersioned
# Default is alias for .stagedversioned
SilverStripe\Versioned\Versioned: '%$SilverStripe\Versioned\Versioned.stagedversioned'
```
Upgrade your extension references as below:
```diff
class MyClass extends DataObject {
private static $extensions = [
- Versioned::class . '(Versioned)',
+ Versioned::class . '.versioned',
];
}
```
