Set phpredis multi() mode parameter

[fbnfgc]

Set the default function parameter to avoid potential issues when a Redis proxy is used instead of the internal class.

This issue has been discussed in phpredis/phpredis#1476 (comment) and snc/SncRedisBundle#442.

This may be Symfony specific, but I'd be happy to hear your thoughts on this issue.

This is fine I guess, but should be rebased on 1.x branch as the problem exists there too.

[fbnfgc]

Just cherry-picked the commit and applied it to the 1.x branch.

Tests now fails but it shouldn't.

1) Monolog\Handler\RedisHandlerTest::testRedisHandleCapped
Error: Undefined class constant 'MULTI'

I need to dig into, some tests were skipped because phpredis is not available on the CI.

[Seldaek]

Yeah the extension isn't loaded I believe in the tests.. Either mark more tests as skipped or maybe fix the patch so it uses defined('Redis::MULTI') ? Redis::MULTI : 1 or whatever the value of Redis::MULTI is when the ext is loaded..

Thanks, fixed as suggested.
