This Pull Request concern severals components, the purpose here is to notify in dev mode that in a case of inherit class, a function will have a new or severals arguments in Symfony 5.0, therefore not implement it is deprecated since Symfony 4.2
The function is made by these conditions :
1- ```(func_num_args() < $x)``` where [x] is the number of arguments we will have in Symfony 5.0
this check allow to verify that the arguments are missing
2- ```(__CLASS__ !== \get_class($this))```
this check allow to verify that the name of the class is different than the base class, therefore that we are in the child class
3- ```(__CLASS__ !== (new \ReflectionMethod($this, __FUNCTION__))->getDeclaringClass()->getName())```
this check allow to verify that the class of the current function is different than the base class, therefore the function has been rewrote into the child class
Code exemple :
```
public function method(/* void $myNewArgument = null */)
{
if ((func_num_args() < 1) && (__CLASS__ !== \get_class($this)) && (__CLASS__ !== (new \ReflectionMethod($this, __FUNCTION__))->getDeclaringClass()->getName())){
@trigger_error(sprintf('The "%s()" method will have one `void $myNewArgument = null` argument in version 5.0 and higher.Not defining it is deprecated since Symfony 4.2.', __METHOD__ ), E_USER_DEPRECATED);
}
// do something
}
```
The unit test are made by creating a child Class using for the tested function ```return parent::function()``` and by calling this child class and catching the expected depreciation message
