REDIS - set up error?

froddy · 2013-11-20 21:52:54 UTC

Hi,

I've just changed from memcached to redis. Unless I'm logged in to the matrix admin backend I get this error? Also get it when serving up same pages as https. If I change back to memcached all works as expected. Any help appreciated.

Fatal error: Cannot use object of type Redis as array in /var/www/matrix/core/assets/system/cache_storage/cache_storage_types/cache_storage_redis/cache_storage_redis.inc on line 200 Call Stack: 0.0001 629808 1. {main}() /var/www/matrix/core/web/index.php:0 0.0289 5157096 2.

Now upgraded to 4.18.0 but still get this error unless logged in. Any idea what's wrong? I'm guessing I've misconfigured REDIS or something like that? Anyone got an example of the REDIS config files?

REDIS.inc config:

<?php // Hosts are tried in order, first successful connection wins!
$redis = Array(
       'hosts' =>Array (
               'redis1' => Array(
                       'socket' => false,
                       'host'   => 'localhost',
                       'port' => 6379
               )
       ),

       // List of Matrix services utilising the above servers.
       // Indexed by key => weight.
       'services' => Array(
               'cache_manager'     => Array('redis1' => 1),
       ),
);

return $redis;
?>

Hi Froddy,

I'm almost certain this is bug #6618 http://bugs.matrix.squiz.net/view_bug.php?bug_id=6618

Which was introduced in 4.18.0 and resolved in 4.18.1.

If you don't want to do a full upgrade you can patch in the fix to core/assets/system/cache_storage/cache_storage_types/cache_storage_redis/cache_storage_redis.inc

Line 192 Should read

$ret = $this->_redis->sadd(SQ_CACHE_REDIS_URL_INDEX_PREFIX.$index_url, $mcache_key)

not

$this->_redis->sadd(SQ_CACHE_REDIS_URL_INDEX_PREFIX.$index_url, $mcache_key)

Hope that helps!

Thanks

Hamish

Thank you for sharing.
I must say php redis extension has definitely stormed in the areas of smart developers, as with extraordinary data types like Sorted Set which provide ordered from the smallest score to the largest, it sure marking in the dev world. Thanks for sharing!
