Resque::TaggedQueues

Tagged queues for Resque.

In travis-ci we need workers to be able to only pull jobs that match their capabilities. E.g. a build job might be configured to require Postges or MongoDB. Then a worker should only pull that job if it has that capability.

Resque::TaggedQueues tackles this problem by defining a tagging syntax for queue names. Before pulling a job it will find all queues from Redis for which the worker has all tags that the queue requires.

E.g.:

Lets say the worker has 1.8.7, 1.9.2 and ree installed but it does not support jruby. It can define that by using a queue like `builds[1.8.7,1.9.2,ree]`.

Now the application queues jobs in the queues `builds[1.8.7]`, `builds[1.9.2]` and `builds[jruby]`. Then the worker will pull the jobs from `builds[1.8.7]` and `builds[1.9.2]` but ignore the one in `builds[jruby]`.

Running the tests

$ ruby -rubygems -Ilib -Itest test/tagged_queues_test.rb
