Bug #65629 [NEW]: SplObjectsStorage::detach() rewinds internal pointer
From: alan dot bem at gmail dot com
Operating system:
PHP version: Irrelevant
Package: SPL related
Bug Type: Bug
Bug description:SplObjectsStorage::detach() rewinds internal pointer
Description:
------------
It seems that SplObjectsStorage::detach() internally rewinds its array
pointer.
PHP versions from 5.1.0 to 5.5.3 are affected.
Test script:
---------------
// To see this live, go to: http://3v4l.org/MAELj
<?php
class A
{
public $val;
public function __construct($val) { $this->val = $val; }
}
$storage = new SplObjectStorage;
for($i = 1; $i <= 10; $i++) {
$storage->attach(new A($i));
}
$iterations = 0;
$storage->rewind();
while ($storage->valid()) {
$iterations++;
$object = $storage->current();
echo 'Iteration #' . $iterations . ' with object A(' . $object->val .
')';
$storage->next();
if($iterations === 2 || $iterations === 8) {
$storage->detach($object);
echo ' - deleted Object A(' . $object->val . ') ';
}
echo PHP_EOL;
}
echo 'Number of iterations: ' . $iterations . PHP_EOL;
Expected result:
----------------
Iteration #1 with object A(1)
Iteration #2 with object A(2) - deleted Object A(2)
Iteration #3 with object A(3)
Iteration #4 with object A(4)
Iteration #5 with object A(5)
Iteration #6 with object A(6)
Iteration #7 with object A(7) - deleted Object A(7)
Iteration #8 with object A(8)
Iteration #9 with object A(9)
Iteration #10 with object A(10)
Number of iterations: 10
Actual result:
--------------
Iteration #1 with object A(1)
Iteration #2 with object A(2) - deleted Object A(2)
Iteration #3 with object A(1)
Iteration #4 with object A(3)
Iteration #5 with object A(4)
Iteration #6 with object A(5)
Iteration #7 with object A(6)
Iteration #8 with object A(7) - deleted Object A(7)
Iteration #9 with object A(1)
Iteration #10 with object A(3)
Iteration #11 with object A(4)
Iteration #12 with object A(5)
Iteration #13 with object A(6)
Iteration #14 with object A(8)
Iteration #15 with object A(9)
Iteration #16 with object A(10)
Number of iterations: 16
