collectiveidea / delayed_job_active_record

ActiveRecord backend integration for DelayedJob 3.0+

If you're viewing this at https://github.com/collectiveidea/delayed_job_active_record, you're reading the documentation for the master branch. View documentation for the latest release (4.1.7).

DelayedJob ActiveRecord Backend

Installation

Add the gem to your Gemfile:

gem 'delayed_job_active_record'

Run bundle install.

If you're using Rails, run the generator to create the migration for the delayed_job table.

rails g delayed_job:active_record
rake db:migrate

Problems locking jobs

You can try using the legacy locking code. It is usually slower but works better for certain people.

Delayed::Backend::ActiveRecord.configuration.reserve_sql_strategy = :default_sql

Upgrading from 2.x to 3.0.0

If you're upgrading from Delayed Job 2.x, run the upgrade generator to create a migration to add a column to your delayed_jobs table.

rails g delayed_job:upgrade
rake db:migrate

That's it. Use delayed_job as normal.

delayed_job_active_record's Issues

clean rails3 app raises ActiveRecord::ConnectionNotEstablished

to reproduce:

$ rails new railsfail
$ echo "gem 'delayed_job_active_record'" >> Gemfile
$ bundle install

$ bundle exec rake -T
rake aborted!
ActiveRecord::ConnectionNotEstablished

$ bundle exec rails g delayed_job:active_record
/Users/nessence/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:318:in retrieve_connection': ActiveRecord::ConnectionNotEstablished (ActiveRecord::ConnectionNotEstablished) ... from /Users/nessence/.rvm/gems/ruby-1.9.2-p290/gems/delayed_job_active_record-0.3.1/lib/delayed/backend/active_record.rb:25:inclass:Job'
...

Also caused by simple command-line use:
$ irb
1.9.2-p290 :001 > require 'rubygems'
=> false
1.9.2-p290 :002 > require 'delayed_job_active_record'
ActiveRecord::ConnectionNotEstablished: ActiveRecord::ConnectionNotEstablished

This is from a fresh install of ruby via 'rvm install 1.9.2' and is triggered by the call to scope in active_record.rb (see trace).

What's the best way around this bug and/or to [safely] establish a connection for DJ before the ActiveRecord model is evaluated? [w/o upgrading rails]

For reference

$ rails g delayed_job:upgrade
DEPRECATION WARNING: Calling set_table_name is deprecated. Please use `self.table_name = 'the_name'` instead. (called from <top (required)> at /Users/me/myapp/config/application.rb:7)

(FWIW, I believe the deprecation warning is a rake problem, not a delayed_job problem.)

DJ Logging every 5 seconds

Anyone have any input on the comment to this change?

940bf92#commitcomment-3843200

Jobs run multiple times with Rails 3.2.13

Upgraded to Rails 3.2.13. Seeing jobs run multiple times, likely due to being picked up by multiple workers. Not respecting the lock fields, or losing them in scoping? Tried to pick out the specific queries in the log, but I couldn't suss out the issue. Reverting to Rails 3.2.12 fixes the problem.

Perhaps due to rails/rails@f980289

Unable to have DJ tasks available in an engine

I'm trying to use delayed_job_active_record in an engine, but the problem I'm facing is that rake tasks are not available after the bundle install.
I've noticed that the delayed_job_active_record.rb in the lib has a ruby require 'delayed_job' and delayed_job.rb has a ruby require 'delayed/railtie' if defined?(Rails::Railtie) .
So I don't know what I missing if there's a Railtie that loads the tasks. Is this an issue with delayed_job_active_record? or am I missing something?

including gem 'delayed_job_active_record' causes [BUG] Segmentation fault ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0]

I am using rails 3.2.6, ruby 1.9.3-p194 on a mac.

Whenever I include the gem and run "rails c", it will crash with the following error:

[BUG] Segmentation fault

Delayed_Job dies without error while running as Deamons on Ubuntu 12.04

running: /bin/delayed_job status

gives: pid-file for killed process 1143 found (/appPath/tmp/pids/delayed_job.pid),
deleting. delayed_job: no instances running

The strange thing is if I use: /bin/delayed_job start It will run perfectly in the foreground! And never dies.

How to debug this?. Is this segfaults?

Using:
rails (4.1.0)
delayed_job_active_record(4.0.1)

jobs closed unexpectedly - data too long for text column

When job fail because of data too long in mysql request, the job process is also finished...

Example :

class Example
  def self.test
    i = 'i'
    100000.times do
      i+= 'i'
    end
    MyModel.create(my_text_column: i)
  end
end

Example.delay.test

rake jobs:work

Migration is not generated

I've added delayed_job_active_record gem to my Gemfile, ran rails g delayed_job , it created DJ bin file, made it executable but doesn't create migration. Had to do this manualy.

Ruby 1.9.2, Rails 3.1.1, latest DJ

max_run_time = 0 means something different to Delayed::Worker than it does to Delayed::Backend::ActiveRecord:: Job.ready_to_run

Setting the Delayed::Worker.max_run_time to zero indicates that the Worker should not time out long running jobs. That is because it uses the Timeout library for managing timeout logic, and that is what zero means to that library.

However, the ready_to_run query doesn't special case that value, so it will end up selecting basically any job as "ready to run", because the conditional "OR locked_at < ?" (where ? = db_time_now - max_run_time) will almost always be true.

Make test suite independent of delayed_job test suite

Hello,

I am packaging your gem for Fedora. I was trying to execute the test suite while I was facing this error:

/usr/share/rubygems/rubygems/custom_require.rb:36:in `require': cannot load such file -- /usr/share/gems/gems/delayed_job-3.0.2/spec/sample_jobs (LoadError)

The reason for this error is that we typically don't install test suite with the main package, since it is not needed by regular user, and we install it just as a part of documentation subpackage. So if I add the dependency just on the gem (without documentation, as I always do), I am facing this error.

Now I am wondering, if you would consider to split the test suite. I have never seen before test suite which depends on another gem's test suite. This is not a show stopper, of course I can depend on the documentation subpackage and test suite passes.

I understand, that this is rather academic problem. However, I'd love to know your opinion. Thank you.

Failed jobs not correctly unlocked first time through

When I tried to upgrade rails to version 3.2.2 (from version 3.1.3), I notice that when a job failed it was run a second time right away.

The cause of this problem is that the job is not being unlocked correctly. I found an old issue that had the same problem here: collectiveidea/delayed_job#63.

What I found is that when first locking the job, only the locks on the database are changed, not those of the object itself, so when the job is unlocked, the locked_by and locked_at attributes are not correctly updated.

I managed to work around the issue by calling self.reload instead of :

self.locked_at = now
self.locked_by = worker
self.locked_at_will_change!
self.locked_by_will_change!

This fix may cause a performance issue, and there is probably a better/cleaner way to solve this.

using :
rails version 3.2.2
delayed_job version 3.0.1
delayed_job_active_record version 0.3.2
using SQLite3 (gem 1.3.5)

Generated migration does not work in Rails 3.0

It uses the "change" method, which is silently ignored on Rails 3.0. It might be easier to stick with the old up / down style, or you'll need to check the Rails version.

Update the README

Can you please update the README with explanation that 4.0.0 version is actually compatible with Rails 3 and Delayed Job 3 versions as well.

I updated an old version of the gem and got from 0.3.5 to 4.0.0 and it's wasn't obvious for me if I can run it or not.

Thanks

Can't start delayed_job with a named Queue in 0.4.4

Steps to reproduce:
script/delayed_job -i 0 --queue=Stitch run
or
Delayed::Backend::ActiveRecord::Job.where(:queue => ["Stitch"])
Gets me a :
NoMethodError: undefined method abstract_class?' for Object:Class`

I managed to track it down in file active_record.rb#L50
ready_scope = ready_scope.where(:queue => Worker.queues) if Worker.queues.any?

It seems that AR somehow chokes on a where clause with an Array input. Also it works fine in 0.4.3 since it 's using an IN clause instead.

Gem Versions:

• delayed_job (3.0.5)
• delayed_job_active_record (0.4.4)

Upgrade to 0.4.0 breaks daemon

I just upgraded to the newer version and had to revert back to the old one. When daemonizing the delayed_job, it will not load the daemon.

#!/usr/bin/env ruby

require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
ARGV << "--pid-dir=#{Rails.root}/pids"
Delayed::Command.new(ARGV).daemonize

When running Rails 4 with Rails 3 mass-assignment compatibility gem, DJ fails with mass-assignment error

Rails 4 lets you include a gem called 'protected_attributes' which turns on Rails 3-style mass-assignment protection. This provides an easier migration path for people moving to Rails 4 and will probably be pretty commonly used as a stop-gap solution by some Rails projects.

Using this Gem with DJ on Rails 4 causes DJ to fail because the payload_object is never mass-assigned. When you attempt to create a delayed job, you'll get this warning:

WARNING: Can't mass-assign protected attributes for Delayed::Backend::ActiveRecord::Job: priority, queue, payload_object

Then, in your worker process you'll get this error:
undefined method `[]' for nil:NilClass

This is because payload_object is nil and can't be deserialized.

Probably the way to fix this is in lib/delayed/backend/active_record.rb, change this code to look for the inclusion of the 'protected_attributes' gem instead of or in addition to the version number of ActiveRecord:

        if ::ActiveRecord::VERSION::MAJOR < 4
          attr_accessible :priority, :run_at, :queue, :payload_object,
                          :failed_at, :locked_at, :locked_by
        end

Time object millisecond precision for mysql(>5.6.4) version

ActiveSupport::TimeZone object for rails 4.2 beta version is returning millisecond precision, detailed mention here in this rails issue. Due to this delayed job queue is not executed when it's not empty.

when "MySQL", "Mysql2"
 count = ready_scope.limit(1).update_all(locked_at: now, locked_by: worker.name)
 return nil if count == 0
 where(locked_at: now, locked_by: worker.name, failed_at: nil).first

so the locked_at time is being set with
UPDATE delayed_jobs SET delayed_jobs.locked_at = '2014-10-21 05:14:39.499297'
as mentioned in the rails issue above.
The locked_at column generated by the delayed_job active record migration doesn't have ability to store the precision. So the precision is discarded and stored. But running the where clause here

 where(locked_at: now, locked_by: worker.name, failed_at: nil).first

The precision is not discarded for mysql versions(>= 5.6.4), so the where clause is queried with precision which doesn't result any results, which makes delayed job think there are no records to run.

So for the delayed job to work, i made this change in my pull request

       when "MySQL", "Mysql2"
        #removing the millisecond precision from now(time object),mysql 5.6.4 onwards millisecond precision exists, but the datetime object created doesn't have precision, so discarded while updating. But during the where clause, for mysql(>=5.6.4), it queries with precision as well. So removing the precision.

        now = now.change(:usec => 0)
        ##### This works on MySQL and possibly some other DBs that support UPDATE...LIMIT. It uses separate queries to lock and return the job
        count = ready_scope.limit(1).update_all(locked_at: now, locked_by: worker.name)
        return nil if count == 0
        where(locked_at: now, locked_by: worker.name, failed_at: nil).first

Where is the find_available method defined?

Hi,

I'm trying to understand how available jobs are selected to be processed and I stumbled upon the following code in base.rb from the delayed_job repositery:

def reserve(worker, max_run_time = Worker.max_run_time)
  # We get up to 5 jobs from the db. In case we cannot get exclusive access to a job we try the next.
  # this leads to a more even distribution of jobs across the worker processes
  find_available(worker.name, worker.read_ahead, max_run_time).detect do |job|
    job.lock_exclusively!(max_run_time, worker.name)
  end
end

I can't find where the find_available method is defined. Does not seem to be in the from the delayed_job gem but I can't find it here either. Any idea where I can find the method definition?

Locking no longer functions correctly

I upgraded from v0.4.1 to v0.4.3 and found that the job locking no longer functions correctly (using Rails 3.2.12 and Postgresql 9.1).

I have certain jobs setup to requeue themselves upon completion. Multiple workers pick up the same job, run it, and queue the same job multiple times, resulting in one job becoming 2-3 jobs. They in turn get picked up and run and create more.

As it stand, I have about 7 jobs queued when only 1 should be there. It worked great with 0.4.1 and the issue seems to have been introduced in these commits:

b015618
0cb4496

For now, I have rolled back to v0.4.1 and the bug has gone away.

Blowing up on Rails 3.2.6 with SystemStackError

Been poking at this for hours now. Job enqueuing via the "delay" method is resulting in my app blowing up with a SystemStackError when running on a local server (both WebBrick and Thin tested) with the debugger attached. I'm running Rails 3.2.6 on both Ruby 1.9.2 and 1.9.3 and delayed_job_active_record v 0.3.2. Oddly, if I invoke the very same methods that are blowing up in the app from the Rails interactive console instead or even from the app running on the development server WITHOUT debugging enabled, they work fine. the delayed_job log isn't giving me any help.

The particular invocation I'm testing is:

OrderMailer.delay.send_order_confirmation_email(@order)

(OrderMailer.send_order_confirmation_email does just what it sounds like it does)

Again, this works fine if invoked from the interactive console but not from the app. The stack trace I'm seeing (though I doubt it's helpful) is:

SystemStackError (stack level too deep):
activesupport (3.2.6) lib/active_support/callbacks.rb:409

Rendered /Users/[me]/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.2.6/lib/action_dispatch/middleware/templates/rescues/_trace.erb (2.1ms)

...which I take is the framework killing the handling of the request because the stack level has surpassed a threshold, so likely not so helpful in actually diagnosing the issue. Will answer any other questions if it will help. Thanks.

ActiveRecord::StatementInvalid (Could not find table 'delayed_jobs')

Hey guys,

When some application set AR configurations below:

active_record.table_name_prefix = "my_app_"
active_record.table_name_suffix = ""

and run migrations, AR creates a table with name "my_app_delayed_jobs"

Then DJ AR Backend try to query with name "delayed_jobs" and you get the Error:
ActiveRecord::StatementInvalid (Could not find table 'delayed_jobs'):
or
ActiveRecord::JdbcError (query does not return ResultSet):
If application using activerecord-jdbc-adapter

Is it possible to set DJ table name with AR prefix and suffix configs?
something like this:

self.table_name = "#{::ActiveRecord::Base.table_name_prefix}delayed_jobs#{::ActiveRecord::Base.table_name_suffix}"

Using

• delayed_job (3.0.1)
• delayed_job_active_record (0.3.2)
• rails (3.1.3)
• activerecord (3.1.3)

Mysql2::Error: Deadlock when attempting to lock a job

We've just upgraded from 0.3.3 to 0.4.4, to resolve the race condition problem when running multiple workers. We're now seeing occasional MySQL deadlocks, which are unhandled exceptions and end up killing the worker.

For example:

svc1 Jun  5 12:35:17  Mysql2::Error: Deadlock found when trying to get lock; try restarting transaction: UPDATE `delayed_jobs` SET `locked_at` = '2013-06-05 12:35:16', `locked_by` = 'delayed_job.2 host:svc1 pid:20498' WHERE `delayed_jobs`.`queue` IN ('batch') AND ((run_at <= '2013-06-05 12:35:16' AND (locked_at IS NULL OR locked_at < '2013-06-05 08:35:16') OR locked_by = 'delayed_job.2 host:svc1 pid:20498') AND failed_at IS NULL) ORDER BY priority ASC, run_at ASC LIMIT 1

It would seem that, at the very least, this should be handled.

In case it matters, we're using delayed_job 3.0.4.

ActiveRecord::JDBCError: The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified

Getting this error with delayed_job_active_record 0.4.4 on server start-up while trying to pick the first delayed_job record.

Using activerecord-jdbcmssql-adapter 1.2.5 or 1.2.9

It works fine with delayed_job_active_record 0.3.3

I could not find any requirements regarding PostgreSQL Version. It would be good if you would support the latest database version on the latest major enterprise linux distribution.

Support for Rails 4.1

I'm eager to play around with Rails 4.1 on my app, but I notice that DJ doesn't officially support it yet. The release notes suggest that there should be little broken compatibility, which should (hopefully!) make supporting 4.1 fairly painless. Looking forward to checking out DJ in 4.1.

ActiveRecord / oracle-enhanced-adapter includes mystery column "JOB_ID" in enqueue insert

Rails 3.2.13, Ruby 1.9.3
Using 4.0.0 delayed_job / delayed_job_active_record

Enqueue seems to be trying to send a job_id to the insert, but I can't figure out where this column is coming from. Job_id doesn't exist in the delayed_jobs table obviously...assuming it is related to my use of oracle-enhanced which I'm not sure is supported.

Note the JOB_ID column in the insert, with a value pair of [nil,27], where 27 is the delayed_job table sequence nextval. Looks like somehow the delayed_job_id column is getting crossed up and this job_id is getting added.

In console:

INSERT INTO "DELAYED_JOBS" ("ATTEMPTS", "CREATED_AT", "DELAYED_JOB_ID", "FAILED_AT", "HANDLER", "JOB_ID", "LAST_ERROR", "LOCKED_AT", "LOCKED_BY", "PRIORITY", "QUEUE", "RUN_AT", "UPDATED_AT") VALUES (:a1, :a2, :a3, :a4, :a5, :a6, :a7, :a8, :a9, :a10, :a11, :a12, :a13) [["attempts", 0], ["created_at", Fri, 16 Aug 2013 18:58:37 UTC +00:00], ["delayed_job_id", nil], ["failed_at", nil], ["handler", "---!ruby/object:Delayed::PerformableMethod\nobject: !ruby/object:QueueProcessor {}\nmethod_name: :perform\nargs: []\n"], [nil, 27], ["last_error", nil], ["locked_at", nil], ["locked_by", nil], ["priority", 0], ["queue", nil], ["run_at", Fri, 16 Aug 2013 18:58:37 UTC +00:00], ["updated_at",Fri, 16 Aug 2013 18:58:37 UTC +00:00]]

Any help appreciated...I'd prefer not to write my own if I can make delayed_jobs work!

Delayed::DeserializationError: Job failed to load: undefined method `engine' for nil:NilClass.

Not sure if this is a bug with delayed_job_active_record but I just wanted to run it with others who may be getting this issue.

I have a UserMailer class which accepts a user and a collection of products and I perform this method with delayed jobs like below.

  UserMailer.delay.send_products_update_notification(user, my_products)

For some weird reason when my_products is an ActiveRecord::Relation::ActiveRecord_Relation_Product by doing my_products.class I receive the following error when my job is being run.

  Delayed::DeserializationError: Job failed to load: undefined method `engine' for nil:NilClass.

But as soon as I change my mailer by converting my_products to an array my task works.

   UserMailer.delay.send_products_update_notification(user, my_products.to_a)

Not sure if I am doing something wrong here of that it's a known issue with the gem. If anyone has any insight as to why this could be happening, that would be helpful. Thanks.

Locking raises errors when replicated over MySQL slaves

We're getting loads of things like this in our MySQL master/slave setup:

130731 13:14:46 [Warning] Statement may not be safe to log in statement format. Statement: UPDATE `delayed_jobs` SET `locked_at` = '2013-07-31 13:14:46', `locked_by` = 'host:server-1 pid:14412' WHERE ((run_at <= '2013-07-31 13:14:46' AND (locked_at IS NULL OR locked_at < '2013-07-31 09:14:46') OR locked_by = 'host:server-1 pid:14412') AND failed_at IS NULL) ORDER BY priority ASC, run_at ASC LIMIT 1

which appears to be the same error as raised in collectiveidea/delayed_job#219. We're using 0.4.4 but the same code appears in the latest version.

Major version bump

The delayed_job project, from which this codebase is derived, dates back to 2009. This particular gem was released in 2011 and has thousands of users running it in production.

Quoting from the Semantic Versioning FAQ:

If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you're worrying a lot about backwards compatibility, you should probably already be 1.0.0.

By this definition, this library should already be 1.0.0.

I have experimented with releasing 4.0.0.beta versions of this gem, to bring the versioning in line with delayed_job and rails both of which are in 4.0.0.beta. That said, I'm not set on making the big jump to 4.0.0, especially if we're planning to maintain compatibility with earlier versions of delayed_job and rails, as we seem to have been able to achieve with #49.

Is there any compelling reason to ship another patch (0.4.5) or minor (0.5.0) version before making the jump to 1.0.0 or 4.0.0?

My only hesitation is to wait until delayed_job and rails release 4.0.0 versions, to ensure we are compatible with the final releases, not just the betas.

MySQL Locking subject to race conditions

the ActiveRecord backend is subject to race conditions if you're running worker processes on different machines.

Because the MySQL path does not use SELECT FOR UPDATE but a manual multi-query lock process we're seeing that each machine running delayed job runs the same job.

The POSTGRES path seems more appropriate for MySQL with innodb as this should lock the row in the database properly.

Any one got any advice on how we can patch this adapater (and send a pull) to resolve this?

performance regression from 0.4.3 to 0.4.4

I upgraded to 0.4.4 and deployed only to find that time between jobs went from < 1s to > 20s. That is a huge swing. I've reverted but thought others should know. This is on a mysql 5.1 server.

reschedule_at not working correctly

Im having problems with reschedule_at working properly. My worker will always make two attempts in quick succession upon failure no matter what I set reschedule_at to. I've done some research and it it looks like there's an issue with locked_by being set when it shouldn't. Either that or the logic in ready_to_run should include some extra parenthesis so that locked_by doesnt override run_at being > db_time_now.

Here's an example, where I included some debugging lines

in worker.rb:

def reschedule(job, time = nil)
  if (job.attempts += 1) < max_attempts(job)
    puts "Rescheduling"
    time ||= job.reschedule_at
    job.run_at = time
    puts "just set run at to #{time}"
    puts "locket_at: #{job.locked_at}"
    puts "locket_by: #{job.locked_by}"
    job.unlock
    puts 'just unlocked'
    job.save!
    puts 'just saved'
    puts "locket_at: #{job.locked_at}"
    puts "locket_by: #{job.locked_by}"
  else
    say "PERMANENTLY removing #{job.name} because of #{job.attempts} consecutive failures.", Logger::INFO
    failed(job)
  end
end

in active_record.rb:

def self.ready_to_run(worker_name, max_run_time)
  puts "Ready to run"
  puts "db_time_now: #{db_time_now}"
  puts "run_at: #{where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name).first.run_at rescue nil}"
  puts "locked_at: #{where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name).first.locked_at rescue nil}"
  puts "locked_by: #{where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name).first.locked_by rescue nil}"
  where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name)
end

When I run a single delayed job that intentionally raises an exception, I get output that looks like this:

Ready to run
db_time_now: 2013-02-22 11:55:10 -0500
run_at: 2013-02-22 11:54:58 -0500
locked_at:
locked_by:

(job fails so it reschedules...)

Rescheduling
just set run at to 2013-02-22 11:58:20 -0500
locket_at: 2013-02-22 11:55:10 -0500
locket_by: host:Matts-iMac.local pid:32904
just unlocked
just saved
locket_at:
locket_by:

Ready to run
db_time_now: 2013-02-22 11:55:12 -0500
run_at: 2013-02-22 11:58:20 -0500
locked_at:
locked_by: host:Matts-iMac.local pid:32904

(hmmm.. why is locked_at nil but locked_by isn't. Also run_at is > db_time_now so this shouldnt have ran, but it did)

(job fails again...)
Rescheduling
just set run at to 2013-02-22 12:32:39 -0500
locket_at: 2013-02-22 11:55:12 -0500
locket_by: host:Matts-iMac.local pid:32904
just unlocked
just saved
locket_at:
locket_by:

Ready to run
db_time_now: 2013-02-22 11:55:12 -0500
run_at:
locked_at:
locked_by:

(weird.. after a second call to reschedule_at, locked_by is now nil like it probably should be and ready_to_run doesn't find any jobs)

So I'm not sure why locked_by isn't nil, maybe its on purpose, maybe not, but according to the logic in ready_to_run, if locked_by = worker_name, it will override run_at <= db_time_now like so:

where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name)

in another form could be:

(A && (B || C) || D) && E

Since D is chained on the end like that a true value will override A && (B || C)

So is locked_by being set incorrectly, or should the logic be more like (A && ((B || C) || D)) && E ??

Redis::InheritedError

When using Unicorn (or any other forking server) I receive this error from delayed_job:
Redis::InheritedError: Tried to use a connection from a child process without reconnecting. You need to reconnect to Redis after forking.

It doesn't seem to break anything, but errors make me sad. So, I'm thinking this method needs away for folks to hook into to be able to call Rails.cache.reconnect and make the errors go away.

I'm happy to open a PR, but perhaps you could advise me on how to structure this hook in a way that would make you happy?

Worker crashes when having followers (read-only) postgres slaves after merging: 5de3205f13c55b7911fbbfc528ec499204cbf161

The change introduced new query:

self.find_by_sql(["UPDATE #{quotedTableName} SET locked_at = ?, locked_by = ? WHERE id IN (#{nextScope.to_sql}) RETURNING *",now,worker.name])

it seems that find_by_sql is interpreted as "SELECT" query by ActiverRecord/Octopus gem and it tries to execute query on read-only Postgre follower. I guess the issue could be spotted on different envs with DB replicas, but originally I spotted this on Heroku.

For now I rolled back gem to version 0.3.3. I am not very strong with ActiveRecord/Octopus internals to get this fixed. Maybe this should be considered ActiveRecord or Octopus issue.

Failed custom jobs not unlocking on failure

So I have the following issue.

Custom Delayed Jobs (i.e. ones that explicitly define the perform hook) are intermittently failing to unlock on failure.

Do I need to be explicitly resetting the locked_by and locked_at attributes in one of the hooks, say the "after(job)" or "failure" hooks?

MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

I'm using MySQL 5.5.29 and after upgrading to 0.4.0 I get this error:

Support for Rails 4.2

Rails 4.2 has been released today. The gem doesn't support it yet

 spec.add_dependency "activerecord", [">= 3.0", "< 4.2"]

Trouble bundling with Rails 4.0.0-rc1.

Here's what I'm seeing when I try to bundle with Ruby 2.0 and Rails 4.0.0-rc1:

Updating git://github.com/collectiveidea/delayed_job_active_record.git
Fetching gem metadata from https://rubygems.org/.......
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":

      activesupport (~> 3.0) ruby

    rails (= 4.0.0.rc1) ruby depends on
      activesupport (4.0.0.rc1)

Rails 4.0 support?

Hi,
Any plans to upgrade the gem to work in rails 4.0 ?
Right now in the dependencies it say 'activerecord', ['>= 2.1.0', '< 4'], so the gem doesn't work on rails 4.0

locked_by needs an index

Using delayed_job 3.0.1 and delayed_job_active_record 0.3.2 we are seeing a lot of time spent in:

      update_all("locked_by = null, locked_at = null", ["locked_by = ?", worker_name])

(lib/delayed/backend/active_record.rb line 44).

Adding an index to locked_by seems necessary.

Our delayed_jobs table has 2.3 million rows (due to extensive use of run_at), but even at thousands of rows, this would appear to be a significant performance issue.

Possible faulty logic breaking reschedule_at

Im having problems with reschedule_at working properly. My worker will always make two attempts in quick succession upon failure no matter what I set reschedule_at to. I've traced it back to the ready_to_run method at line:

where('(run_at <= ? AND (locked_at IS NULL OR locked_at < ?) OR locked_by = ?) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name)

where the logic boils down to:

(A && (B || C) || D) && E

D is evaluating true when the delayed job has failed, is in the reschedule method, but before the save has taken place as shown below. I think there needs to be an extra set of parenthesis like so: ((B || C) || D)) so that D being true doesn't override the fact that run_at is still <= db_time_now

def reschedule(job, time = nil)
  if (job.attempts += 1) < max_attempts(job)
    time ||= job.reschedule_at
    job.run_at = time
    job.unlock
    job.save!
  else
    say "PERMANENTLY removing #{job.name} because of #{job.attempts} consecutive failures.", Logger::INFO
    failed(job)
  end
end

Essentially I think the line should be

where('(run_at <= ? AND ((locked_at IS NULL OR locked_at < ?) OR locked_by = ?)) AND failed_at IS NULL', db_time_now, db_time_now - max_run_time, worker_name)

I haven't thought about the ramifications of this affecting other things though
