Body
Bit of edge case:

Redis is attached to ZF2 cache via socket.

Doctrine redis cache via DoctrineModule\Cache\ZendStorageCache

It will fail intermittently (and always on Doctrine query error).

Error: 'Could not estabilish connection with Redis instance'

Does not occur with port connection.

If: $redis->getTotalSpace() called against ZF2 Redis Cache Adapter before wrapped in DoctrineModule\Cache\ZendStorageCache -- no error.

@Morning Does this issue still persist? I tried to reproduce this issue but I couldn't.

Can you please post up your test case/config? I will run it on the system with the issue, so I can get more detail.

@Moring I have configured Redis locally with socket (and set port to 0). Then I configured the unit tests to use this socket and fixed the tests to be able to run with different config see #118.

phpunit.xml

        <env name="TESTS_ZEND_CACHE_REDIS_ENABLED" value="true" />
        <env name="TESTS_ZEND_CACHE_REDIS_HOST" value="/var/run/redis/redis.sock" />
        <!-- <env name="TESTS_ZEND_CACHE_REDIS_PORT" value="6379" /> -->
        <env name="TESTS_ZEND_CACHE_REDIS_PASSWORD" value="" />
        <env name="TESTS_ZEND_CACHE_REDIS_DATABASE" value="false" />

Also I noticed a general issue with <env name="TESTS_ZEND_CACHE_*_ENABLED" value="true" /> as this will be casted to PHP boolean true but the tests will check for string true. So you either set this as cli variable or you need to disable this check in tests.

Thanks

@marc-mabe Yes!! Local socket does work under PHP: 7.0.12, Zend Cache 2.7.1. It is great to Redis back again, thank you. Did notice the documentation is a bit off, "lib_options" in the config, not "lib_option" for the serializer.

Closing this one as it seems to work fine.

@Moring I have opened a PR for fixing the doc
Thanks
