Bug description:Unserialize array of objects whose class can't be autoloaded
fail
Description:
------------
We have serialized object of class A and array with 2 such objects
<?php
class A {}
echo serialize(new A()).PHP_EOL;
echo serialize(array(new A(), new A())).PHP_EOL;
?>
Then we write autoload function which throws exception if can't find a file
with
class.
And in first case - we have a normal behaviour (we can catch exception).
In second we have uncaughted exception.
Test script:
---------------
<?php
spl_autoload_register(
function($class) {
if (!file_exists($class.'.php'))
throw new Exception();
require_once $class.'.php';
}
);
try {
var_dump(unserialize('O:1:"A":0:{}'));
echo 'Serialized'.PHP_EOL;
} catch (Exception $e) {
echo 'Failed'.PHP_EOL;
}
try {
var_dump(unserialize('a:2:{i:0;O:1:"A":0:{}i:1;O:1:"A":0:{}}'));
echo 'Serialized'.PHP_EOL;
} catch (Exception $e) {
echo 'Failed'.PHP_EOL;
}
Expected result:
----------------
Failed
Failed
Actual result:
--------------
Failed
PHP Fatal error: Uncaught exception 'Exception' in -:5
Stack trace:
#0 [internal function]: {closure}('A')
#1 [internal function]: spl_autoload_call('A')
