Is storing objects in cache supported? my script fails hard

[firstactivemedia]

I am experimenting with caching config objects in memcache to see if it increases speed or not when I came across a bug.

The code below is standalone stripped out of my site to run on command line just to test. The actual config I want to store is much bigger but the bug shows here too.

When the code runs, the config file is saved to the cache fine, I can see it with telnet and when I run

    $memcache_obj = new Memcache;
    $memcache_obj->connect('127.0.0.1', 11211);
    $config = $memcache_obj->get($key);

it comes back just fine, but I can't retrieve the config file with phalcon. (if I set the key value to "hello world" it works fine)

But worse it fails with no error message. I have error logging to show everything end even log to file. I wrote a call to a function that doesn't exist and it does show on both the command line and the php error log so I know that is working.

I believe I have ruled everything, and it has to be a phalcon issue.

<?php
$key = 'config';

$front = new Phalcon\Cache\Frontend\Data(array(
    "lifetime" => 3600
));
//Create the Cache setting memcached connection options
$cache = new Phalcon\Cache\Backend\Memcache($front, array(
    'host' => 'localhost',
    'port' => 11211,
    'persistent' => false
));

if($cache->exists($key))
{
    echo 'getting ',$key," from cache! we do get here if the key exists \n";
    $config = $cache->get($key);

    echo "this never runs, (and never shows an error)  :-( the script ends before here \n";
}

if(empty($config))
{
    $config = new \Phalcon\Config(array(
        'database' => array(
            'adapter'  => 'Mysql',
            'host'     => 'localhost',
            'username' => 'test',
            'password' => 'test',
            'name'     => 'test',
        ),

        'application' => array(
            'controllersDir' => __DIR__ . '/../../app/controllers/',
            'modelsDir'      => __DIR__ . '/../../app/models/',
            'viewsDir'       => __DIR__ . '/../../app/views/',
            'pluginsDir'     => __DIR__ . '/../../app/plugins/',
            'libraryDir'     => __DIR__ . '/../../app/library/',
            'baseUri'        => '/',
        )
    ));
    $cache->save($key, $config);
}

echo '$config : ',gettype($config),"\n";
print_r($config);

I am on fedora14 - 32 bit with the latest master. if I do a git pull I get told it is up to date and git show master says the last commit was : da5d779

In case I wasn't clear when run as part of a webpage it causes Chrome to say Error code: ERR_EMPTY_RESPONSE ... even if there is output earlier in the page

Could you please try 1.2.2? I believe it is b04d46b

[ghost]

Never mind, I can confirm the crash.

[ghost]

Fixed in a2c5980 (1.2.2) and 1be6ab9 (1.3.0)

[ghost]

Did it work for you?

[firstactivemedia]

Sorry for the delay, different timezones I think, plus had the weekend off ;)

Still have the same problem on master and 1.2.2, and have an extra issue with 1.3 which seems to stop it being installed altogether #1001

though based on your pull request title I have also tested with the simpler code as below and have the same issue - dies with no error during unserialize

<?php
$config = new \Phalcon\Config(array(
    'database' => array(
        'adapter'  => 'Mysql',
        'host'     => 'localhost',
        'username' => 'test',
        'password' => 'test',
        'name'     => 'test',
    ),

    'application' => array(
        'controllersDir' => __DIR__ . '/../../app/controllers/',
        'modelsDir'      => __DIR__ . '/../../app/models/',
        'viewsDir'       => __DIR__ . '/../../app/views/',
        'pluginsDir'     => __DIR__ . '/../../app/plugins/',
        'libraryDir'     => __DIR__ . '/../../app/library/',
        'baseUri'        => '/',
    )
));

echo 'Phalcon version : ',\Phalcon\Version::get(),"\n\n";
echo 'Phalcon version id : ',\Phalcon\Version::getId(),"\n\n";

$s = serialize($config);
$config = unserialize($s);
print_r($config);

Phalcon version : 1.2.2
Phalcon version id : 1020240

$ php test.php 
Phalcon version : 1.3.0 ALPHA 1

Phalcon\Config Object
(
    [database] => Phalcon\Config Object
        (
            [adapter] => Mysql

            [username] => test

I tried the script on a 64 bit system

Phalcon version : 1.3.0 ALPHA 1
Phalcon version id : 1030011

still same problem

Also on the 32 bit system 1.3 seems to work on command line despite #1001 but it doesn't fix this issue

[ghost]

I also run the script on 64-bit system… What git revision do you use?

[ghost]

BTW, could you please build phalcon for ext/? build/ files are not regenerated often, ext/ is always fresh

[ghost]

Just tested 1.2.2

Phalcon version : 1.2.2

Phalcon version id : 1020240

Phalcon\Config Object
(
    [database] => Phalcon\Config Object
        (
            [adapter] => Mysql
            [host] => localhost
            [username] => test
            [password] => test
            [name] => test
        )

    [application] => Phalcon\Config Object
        (
            [controllersDir] => /home/vladimir/workspace/cphalcon/../../app/controllers/
            [modelsDir] => /home/vladimir/workspace/cphalcon/../../app/models/
            [viewsDir] => /home/vladimir/workspace/cphalcon/../../app/views/

            [libraryDir] => /home/vladimir/workspace/cphalcon/../../app/library/
            [baseUri] => /
        )

)

1.2.2 is 7915b80
1.3.0 is c800012

All built from ext/

[firstactivemedia]

"could you please build phalcon for ext/?"

sorry not sure how? Also what is the best way to find the git revision?

[ghost]

git clone https://github.com/phalcon/cphalcon.git
git checkout 1.3.0
cd ext
phpize
./configure
make
sudo make install

for 1.2.2 — git checkout 1.2.2

[firstactivemedia]

Cool, that's fixed now, thanks :)
