Memcached and PrestaShop 1.7.4.2

[Kevin]

Hi,

 

Anybody got memcached working with PrestaShop 1.7.4.2?

First of all pressing the Test button will always result in a red box, looks like it's not validated although it is and it's working.

After saving and trying to load the frontpage i get the following error: 

FatalErrorException Error: Maximum execution time of 60 seconds exceeded
in CacheMemcached.php line 94

 

If i debug i see that the set works a lot of times but at one moment it fails(maybe when the set is too big?).

Anybody knows how to solve this?

Thanks,

Kevin

So it looks like it breaks as soon as it tries to set an array with 8561 records.. Anybody has an idea what to do?

For everyone experiencing this problem. It seems memcached cannot handle too large arrays. PrestaShop doesn't check for this.

Solution would be to change the set function of the CacheMemcached.php class to something like:

/**
     * @inheritdoc
     */
    public function set($key, $value, $ttl = 0)
    {
        if(sizeof($value) <= 2000){
            return $this->_set($key, $value, $ttl);
        }else{
            return false;
        }
    }
