/!\ This change fixes a security issue.
Userland exception thrown in a constructor will not be automatically
caught by the mapper anymore. This prevents messages with sensible
information from reaching the final user — for instance an SQL exception
showing a part of a query.
To allow exceptions to be considered as safe, the new method
`MapperBuilder::filterExceptions()` must be used, with caution.
```php
final class SomeClass
{
public function __construct(private string $value)
{
\Webmozart\Assert\Assert::startsWith($value, 'foo_');
}
}
try {
(new \CuyZ\Valinor\MapperBuilder())
->filterExceptions(function (Throwable $exception) {
if ($exception instanceof \Webmozart\Assert\InvalidArgumentException) {
return \CuyZ\Valinor\Mapper\Tree\Message\ThrowableMessage::from($exception);
}
// If the exception should not be caught by this library, it
// must be thrown again.
throw $exception;
})
->mapper()
->map(SomeClass::class, 'bar_baz');
} catch (\CuyZ\Valinor\Mapper\MappingError $exception) {
// Should print something similar to:
// > Expected a value to start with "foo_". Got: "bar_baz"
echo $exception->node()->messages()[0];
}
```
A new class `NodeMessage` is used to wrap messages added to a node
during the mapping. This class will allow further features by giving
access to useful data related to the bound node.
BREAKING CHANGE: as of now every message is wrapped into a `NodeMessage`
it is therefore not possible to check whether the message is an instance
of `Throwable` — a new method `$message->isError()` is now to be used
for such cases.
