Hi,

I’m using mongrel-0.3.13.3 with memcache-client-1.0.3 for storing  
sessions.  
It was working fine with actionpack-1.12.0, but when I upgraded to  
actionpack-1.12.3, I started getting a “can’t convert String into Hash”  
error from memcache.rb from memcache-client.

I was able to fix it by changing the way the MemCache object was created  
in  
actionpack/action\_controller/session/ mem\_cache\_store.rb from:

```
     @cache = options['cache'] || MemCache.new('localhost')

```

to:  
@cache = options[‘cache’] || MemCache.new()  
@cache.servers = ‘localhost’

I’m not sure how this would affect the other Ruby-memcache library, but  
thought this might  
be helpful to anyone else trying to figure out this problem.

yours,  
sness.

Hey Sness, can you try this with webrick to confirm it’s a Mongrel  
problem? It looks like a MemCache issue really.

Hi Zed,

Great idea, thanks. I just tried it with webrick and confirmed that it  
is a  
memcache-client/actionpack issue.

sness.
