Bug ID: 65932
Summary: Validator/ParamParser broken on 5.3 due to autoloader
Product: MediaWiki extensions

Fatal error: Class '\ValueValidators\RangeValidator' not found in
{...}/extensions/Validator/includes/ParamProcessor/ParamDefinitionFactory.php
on line 181
Errors like this pop up on PHP 5.3.
This is because the behaviour for `new $class()` is different between 5.3 and
5.4.
For this:
new \Foo\Bar();
In both 5.3 and 5.4 the autoloader will get the string 'Foo\Bar'.
But for this:
$class = '\Foo\Bar';
new $class();
PHP 5.4 will clean up the class name and the autoloader will get the string
'Foo\Bar'.
PHP 5.3 will leave it alone and the autoloader will get the string '\Foo\Bar'.
As a result when class names like '\ValueValidators\RangeValidator' and
'\ValueValidators\NullValidator' are used, PHP 5.3 won't find any class.
ParamDefinitionFactory::newDefinition needs to strip leading \'s from
$validator, do it's comparison against '\ValueValidators\NullValidator', and in
the future callers should ideally avoid calling it with the leading \.
