No server available (Windows 7. Rails 3) about dalli HOT 10 CLOSED

I think I've found the problem. Dalli relies on kgio which appears to be linux only. I'll have to build and test this in my Ubuntu virtual environment. The production environment is Linux too so this is just an inconvenience for me: not a show stopper.

Can someone confirm that Dalli is Linux/Mac only?

Dalli should be working fine without kgio. Could you please connect using telnet again and type "version" + RETURN. Which version does it report? You need memcached > 1.4.

from dalli.

I've just been looking through socket.rb and now see that Dalli doesn't rely on kgio. My mistake.

My memcache version is 1.2.4. It looks like that's the problem.

Now all I have to do is get a newer version working under windows. I thought installing a windows version had been a little easy :o).

I'll install a newer version of memcached and get back to you with the result.

I've installed membase's mecached server (went the route of finding another binary rather than building from source) and that has installed version 1.6.0beta.

Everything now appears to be working fine.

Thank you very much gucki for your prompt and useful response.

Also, keep in mind that localhost != 127.0.0.1 on some modern machines which default to IPv6.

gucki, this is why I had the version detection. I hope this does not become a recurring support issue. Maybe we need a troubleshooting guide.

This looks like the stack trace that I was getting on my Mac when localhost mapped to the IPv6 address. There are two workarounds. The first is to use 127.0.0.1 instead of localhost: Dalli::Client.new("127.0.0.1"). The second workaround, which worked on my Mac, was to edit the /etc/hosts file and remove the IPv6 mappings.

gucki: an old problem version of memcached was drive me crazy. Some message error like "check your memcache version, 1.4 o greather required" had make it more easy ;-)

Man that was painful. Wish it could detect the wrong version & say so rather than not connecting

from dalli.

I think you need to install sasl component for memcache

Any further advice on Windows connectivity for Memcache with Dalli? It feels impossible to find any Windows-compatible memcache version over <1.4. Even Heroku's documentation on this is out of date.
