ruby on rails - How resque removes job from the queue? -

-

i have implemented resque queuing system in rails app. want know flow of resque job starting enqueue removed out queue.

the traditional work flow, along method used gem is,
1. resque enqueue job(resque::job.create) ,
2. job calls 'perform' method of class(resque::job.perform), and
3. resque removes job queue.

i debugged gem find out method used in step 3, couldn't find it. methods resque::job.destroy, resque::job.dequeue not responsible task, debugged. can tell me method using remove job queue
.
please note that, not want remove job explicitly, want typical resque method removes job queue.

thanks in advance.

resque uses 'dequeue' method remove job:

  def dequeue(klass, *args)     job.destroy(queue_from_class(klass), klass, *args)   end

to pick job queue processing uses 'pop' method:

  def pop(queue)     decode redis.lpop("queue:#{queue}")   end

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
