Forks

collectiveidea

• script/delayed_job / Delayed::Command
• cap tasks
• jewler
• fixed locking to not allow 2nd worker to lock a failed & rescheduled job
• add timeout to job processing
• always return jobs in priority order (no sort_by { rand })
• fix handle_asynchronous to correctly handle punctuated method names
• send_at method

tricycle

• signal handler chaining

weplay

• send_after method (basically same as send_at)
• script/enqueue_job
• job_errors in separate table (Job.has_many :errors)
• wrapped updates in transactions

technoweenie

• Delayed::Worker model, which tracks each job worker process in the DB

eric

• allow for workers to be limited to certain kinds of jobs by setting extra conditions via Delayed::Job.extra_next_task_conditions. The main reason for this is to flexibly allow for server_id and other such attributes to be used as needed.

obvio171

• Keep successfully finished jobs around, store creation/start/end timestamps
• Munin plugins (in /contrib) for graphing queue size and average job run time

tpinto

• server_id column – jobs with this attribute specified should be handled only by workers on the specified machine. we use the hostname. (based on previous work from sbfaulkner)
• more rake tasks (run specific job, lock, unlock)

andrewroth

• based on dsander/delayed_job (recurring jobs)
• add option to specify how many times to recur
• pass a read-only informational hash about the job being run

dburkes

• allow jobs to declare their own MAX_ATTEMPTS value

jsuchal

• optimized fetching of jobs in huge queues. (added indexing)
• Warning: Priority is reversed, so lower priority jobs will run first.

factorylabs

• changed the daemon configuration from collectiveidea fork to allow use in a sinatra app

xspond

• A couple of changes to maintain rails 2.0 compatibility
• Setup a demand based spawner (Still somewhat beta but fully functional)
  • Single daemon dispatcher process forks off each job to its own process to run independently
  • User set max number of concurrently running jobs

ezpub

• Restrict workers to specific job types
• Per job MAX_ATTEMPTS

slaskis

• Uses DataMapper instead of ActiveRecord for ORM.
