Random thoughts as I try to get memcached, sinatra, and heroku to play nice

| sinatra-memcached doesn't work with heroku | |
| because memcache-client doesn't work with heroku | |
| okay, let's rewrite sinatra-memcached to work with dalli, heroku's recommended memcached client | |
| hmm, dalli isn't working on my local install so i can't really test it | |
| why is it failing to connect to localhost? | |
| hmm, dalli requires memcached 1.4+, let's make sure i'm running that | |
| huh, 1.2.8, that's weird because i just installed memcached | |
| `brew info memcached` says it should be in /usr/local/bin, right... | |
| and yet `which memcached` says /usr/bin. uh... wtf | |
| ok, let's just symlink the new memcached into /usr/bin, why the fuck not | |
| oh wow, everything magically works. special... | |
| now if i could just port this "all_keys" method that's monkey patched onto memcached in sinatra-memcached | |
| hmm, i can't get the extra options on stats that it does | |
| maybe i can monkey patch that | |
| looks like i have to send a private method call to the server object, ugh | |
| hmm, so that all_keys method relies on some pretty deprecated cachedump shit | |
| maybe i should just remove the one method that uses that... why would you need to expire by regexp anyway? or something | |
| oh yes, and all the other calls that are using the silly deprecated syntax, right... like you know, set, or [] | |
| huh yeah, that seems to do the trick | |
| let's see, logging correctly... set, get, get, get, set, get, get, get... yup expiry's working | |
| fuck yeah push to heroku DONE | |
| no wait tweet about it now DONE | |

Yes, fairly simple - I'm actually using Dalli::Client.new in the "sinatra-dalli" adapter I put together:
https://github.com/ggilder/muni_dashboard/blob/master/lib/support/sinatra-dalli.rb
You can also manually set the configuration variable for the cache client, so you could use something other than a Dalli::Client instance (or manually create a Dalli::Client instance) as long as it responds to the same methods that are used here.
I might tidy that file up a bit and package it as a gem, and maybe include compatibility with the basic Memcached library if I'm feeling ambitious. ;)
