Operating system: Linux (Debian 5)
PHP version: 5.3.8
Package: memcached
Bug Type: Bug
Bug description:Memcached does not handle invalid keys
Description:
------------
Calling Memcached with invalid keys (too long, invalid characters) leads to
strange behavior.
Calling get with an invalid key and after that getMulti with a valid key
does not
work (see below).
Versions:
memcached support => enabled
libmemcached version => 0.52
PECL:
memcached 1.0.2 stable
Test script:
---------------
<?php
class MemcachedTest extends \PHPUnit_Framework_TestCase
{
public function testSet()
{
$mc = new Memcached();
$mc->addServer('127.0.0.1', 11211);
$mc->get(str_pad('', 300, 'x'));
// it is "NOT FOUND"
$this->assertEquals(Memcached::RES_BAD_KEY_PROVIDED,
$mc->getResultCode());
$mc->getMulti(array('foo'));
// it is "SERVER HAS FAILED AND IS DISABLED UNTIL TIMED RETRY"
$this->assertEquals(Memcached::RES_BAD_KEY_PROVIDED,
$mc->getResultCode());
}
}
Expected result:
----------------
The first $mc->get should lead to a result code "BAD KEY PROVIDED".
The second $mc->getMulti be "NOT FOUND" or "SUCCESS" depending on the cache
content.
Actual result:
--------------
The first $mc->get sets the result code to "NOT FOUND".
The second $mc->getMulti sets the result code to "SERVER HAS FAILED AND IS
DISABLED UNTIL TIMED RETRY".
