fix i18n support resetting saved locale when job is retried [#1011]
log rotation via USR2 now closes the old logger [#1008]
Add ability to customize retry schedule, like so [jmazzi, #1027]

class MyWorker
  include Sidekiq::Worker
  sidekiq_retry_in { |count| count * 2 }
end

Redesign Worker#retries_exhausted callback to use same form as above [jmazzi, #1030]

class MyWorker
  include Sidekiq::Worker
  sidekiq_retries_exhausted do |msg|
    Rails.logger.error "Failed to process #{msg['class']} with args: #{msg['args']}"
  end
end

2.12.4

Fix error in previous release which crashed the Manager when a Processor died.

2.12.3

Revert back to Celluloid's TaskFiber for job processing which has proven to be more stable than TaskThread. [#985]
Avoid possible lockup during hard shutdown [#997]

At this point, if you are experiencing stability issues with Sidekiq in Ruby 1.9, please try Ruby 2.0. It seems to be more stable.

2.12.2

Relax slim version requirement to >= 1.1.0
Refactor historical stats to use TTL, not explicit cleanup. [grosser, #971]

2.12.1

Force Celluloid 0.14.1 as 0.14.0 has a serious bug. [#954]
Scheduled and Retry jobs now use Sidekiq::Client to push jobs onto the queue, so they use client middleware. [dimko, #948]
Record the timestamp when jobs are enqueued. Add Sidekiq::Job#enqueued_at to query the time. [mariovisic, #944]
Add Sidekiq::Queue#latency - calculates diff between now and enqueued_at for the oldest job in the queue.
Add testing method perform_one that dequeues and performs a single job. This is mainly to aid testing jobs that spawn other jobs. [fumin, #963]

2.12.0

Upgrade to Celluloid 0.14, remove the use of Celluloid's thread pool. This should halve the number of threads in each Sidekiq process, thus requiring less resources. [#919]
Abstract Celluloid usage to Sidekiq::Actor for testing purposes.
Better handling for Redis downtime when fetching jobs and shutting down, don't print exceptions every second and print success message when Redis is back.
Fix unclean shutdown leading to duplicate jobs [#897]

2.11.1

Fix timeout warning.
Add Dutch web UI locale.

2.11.0

Upgrade to Celluloid 0.13. [#834]

Add Japanese locale for Web UI [#868]
Fix a few issues with Web UI i18n.

2.10.1

Remove need for the i18n gem. (brandonhilkert)

I18n for web UI. Please submit translations of web/locales/en.yml for your own language. [#811]
'sinatra', 'slim' and 'i18n' are now gem dependencies for Sidekiq.

2.9.0

Update 'sidekiq/testing' to work with any Sidekiq::Client call. It also serializes the arguments as using Redis would. [#713]
Raise a Sidekiq::Shutdown error within workers which don't finish within the hard timeout. This is to prevent unwanted database transaction commits. [#377]
Lazy load Redis connection pool, you no longer need to specify anything in Passenger or Unicorn's after_fork callback [#794]
Add optional Worker#retries_exhausted hook after max retries failed. [jkassemi, #780]
Fix bug in pagination link to last page [pitr, #774]
Upstart scripts for multiple Sidekiq instances [dariocravero, #763]
Use select via pipes instead of poll to catch signals [mrnugget, #761]

2.8.0

I18n support! Sidekiq can optionally save and restore the Rails locale so it will be properly set when your jobs execute. Just include require 'sidekiq/middleware/i18n' in your sidekiq initializer. [#750]
Fix bug which could lose messages when using namespaces and the message needs to be requeued in Redis. [#744]
Refactor Redis namespace support [#747]. The redis namespace can no longer be passed via the config file, the only supported way is via Ruby in your initializer:

sidekiq_redis = { :url => 'redis://localhost:3679', :namespace => 'foo' }
Sidekiq.configure_server { |config| config.redis = sidekiq_redis }
Sidekiq.configure_client { |config| config.redis = sidekiq_redis }

A warning is printed out to the log if a namespace is found in your sidekiq.yml.

2.7.5

Capistrano no longer uses daemonization in order to work with JRuby [#719]
Refactor signal handling to work on Ruby 2.0 [#728, #730]
Fix dashboard refresh URL [#732]

2.7.4

Fixed daemonization, was broken by some internal refactoring in 2.7.3 [#727]

2.7.3

Real-time dashboard is now the default web page
Make config file optional for capistrano
Fix Retry All button in the Web UI

2.7.2

Remove gem signing infrastructure. It was causing Sidekiq to break when used via git in Bundler. This is why we can't have nice things. [#688]

2.7.1

Fix issue with hard shutdown [#680]

2.7.0

Add -d daemonize flag, capistrano recipe has been updated to use it [#662]
Support profiling via ruby-prof with -p. When Sidekiq is stopped via Ctrl-C, it will output profile.html. You must add gem 'ruby-prof' to your Gemfile for it to work.
Dynamically update Redis stats on dashboard [brandonhilkert]
Add Sidekiq::Workers API giving programmatic access to the current set of active workers.

workers = Sidekiq::Workers.new
workers.size => 2
workers.each do |name, work|
  # name is a unique identifier per Processor instance
  # work is a Hash which looks like:
  # { 'queue' => name, 'run_at' => timestamp, 'payload' => msg }
end

Allow environment-specific sections within the config file which override the global values [dtaniwaki, #630]

---
:concurrency:  50
:verbose:      false
staging:
  :verbose:      true
  :concurrency:  5

2.6.5

Several reliability fixes for job requeueing upon termination [apinstein, #622, #624]

Fix crash upon empty queue [#612]

2.6.3

sidekiqctl exits with non-zero exit code upon error [jmazzi]
better argument validation in Sidekiq::Client [karlfreeman]

Add option to log output to a file, reopen log file on USR2 signal [mrnugget, #581]

2.5.4

Sidekiq::Client.push now accepts the worker class as a string so the Sidekiq client does not have to load your worker classes at all. [#524]
Sidekiq::Client.push_bulk now works with inline testing.
Really fix status icon in Web UI this time.
Add "Delete All" and "Retry All" buttons to Retries in Web UI

2.5.3

Small Web UI fixes
Add delay_until so you can delay jobs until a specific timestamp:

Auction.delay_until(@auction.ends_at).close(@auction.id)

This is identical to the existing Sidekiq::Worker method, perform_at.

2.5.2

Remove asset pipeline from Web UI for much faster, simpler runtime. [#499, #490, #481]
Add -g option so the procline better identifies a Sidekiq process, defaults to File.basename(Rails.root). [#486]

sidekiq 2.5.1 myapp [0 of 25 busy]

Logging now uses "MSG-#{Job ID}", not a random msg ID
Allow generic Redis provider as environment variable. [#443]
Add ability to customize sidekiq_options with delay calls [#450]

Foo.delay(:retry => false).bar
Foo.delay(:retry => 10).bar

Foo.delay_for(5.minutes, :timeout => 10.seconds).bar

2.3.3

Remove option to disable Rails hooks. [#401]
Allow delay of any module class method

2.3.2

Fix retry. 2.3.1 accidentally disabled it.

2.3.1

Add Sidekiq::Client.push_bulk for bulk adding of jobs to Redis. My own simple test case shows pushing 10,000 jobs goes from 5 sec to 1.5 sec.
Add support for multiple processes per host to Capistrano recipe
Re-enable Celluloid::Actor#defer to fix stack overflow issues [#398]

2.3.0

Upgrade Celluloid to 0.12
Upgrade Twitter Bootstrap to 2.1.0
Rescue more Exceptions
Change Job ID to be Hex, rather than Base64, for HTTP safety
Use Airbrake#notify_or_ignore

2.2.1

Add support for custom tabs to Sidekiq::Web [#346]
Change capistrano recipe to run 'quiet' before deploy:update_code so it is run upon both 'deploy' and 'deploy:migrations'. [#352]
Rescue Exception rather than StandardError to catch and log any sort of Processor death.

2.2.0

Roll back Celluloid optimizations in 2.1.0 which caused instability.
Add extension to delay any arbitrary class method to Sidekiq. Previously this was limited to ActiveRecord classes.

SomeClass.delay.class_method(1, 'mike', Date.today)

Sidekiq::Client now generates and returns a random, 128-bit Job ID 'jid' which can be used to track the processing of a Job, e.g. for calling back to a webhook when a job is finished.

2.1.1

Handle networking errors causing the scheduler thread to die [#309]
Rework exception handling to log all Processor and actor death (#325, subelsky)
Clone arguments when calling worker so modifications are discarded. (#265, hakanensari)

2.1.0

Tune Celluloid to no longer run message processing within a Fiber. This gives us a full Thread stack and also lowers Sidekiq's memory usage.
Add pagination within the Web UI [#253]
Specify which Redis driver to use: hiredis or ruby (default)
Remove FailureJobs and UniqueJobs, which were optional middleware that I don't want to support in core. [#302]

2.0.3

Fix sidekiq-web's navbar on mobile devices and windows under 980px (ezkl)
Fix Capistrano task for first deploys [#259]
Worker subclasses now properly inherit sidekiq_options set in their superclass [#221]
Add random jitter to scheduler to spread polls across POLL_INTERVAL window. [#247]
Sidekiq has a new mailing list: sidekiq@librelist.org See README.

2.0.2

Fix "Retry Now" button on individual retry page. (ezkl)

2.0.1

Add "Clear Workers" button to UI. If you kill -9 Sidekiq, the workers set can fill up with stale entries.

Update sidekiq/testing to support new scheduled jobs API:

require 'sidekiq/testing'
DirectWorker.perform_in(10.seconds, 1, 2)
assert_equal 1, DirectWorker.jobs.size
assert_in_delta 10.seconds.from_now.to_f, DirectWorker.jobs.last['at'], 0.01

2.0.0

SCHEDULED JOBS!

You can now use perform_at and perform_in to schedule jobs to run at arbitrary points in the future, like so:

  SomeWorker.perform_in(5.days, 'bob', 13)
  SomeWorker.perform_at(5.days.from_now, 'bob', 13)

It also works with the delay extensions:

  UserMailer.delay_for(5.days).send_welcome_email(user.id)

The time is approximately when the job will be placed on the queue; it is not guaranteed to run at precisely at that moment in time.

This functionality is meant for one-off, arbitrary jobs. I still recommend whenever or clockwork if you want cron-like, recurring jobs. See examples/scheduling.rb

I want to specially thank @yabawock for his work on sidekiq-scheduler. His extension for Sidekiq 1.x filled an obvious functional gap that I now think is useful enough to implement in Sidekiq proper.

Fixed issues due to Redis 3.x API changes. Sidekiq now requires the Redis 3.x client.
Inline testing now round trips arguments through JSON to catch serialization issues (betelgeuse)

1.2.1

Sidekiq::Worker now has access to Sidekiq's standard logger
Fix issue with non-StandardErrors leading to Processor exhaustion
Fix issue with Fetcher slowing Sidekiq shutdown
Print backtraces for all threads upon TTIN signal [#183]
Overhaul retries Web UI with new index page and bulk operations [#184]

1.2.0

Full or partial error backtraces can optionally be stored as part of the retry for display in the web UI if you aren't using an error service. [#155]

class Worker
  include Sidekiq::Worker
  sidekiq_options :backtrace => [true || 10]
end

Add timeout option to kill a worker after N seconds (blackgold9)

class HangingWorker
  include Sidekiq::Worker
  sidekiq_options :timeout => 600
  def perform
    # will be killed if it takes longer than 10 minutes
  end
end

Fix delayed extensions not available in workers [#152]
In test environments add the #drain class method to workers. This method executes all previously queued jobs. (panthomakos)
Sidekiq workers can be run inline during tests, just require 'sidekiq/testing/inline' (panthomakos)
Queues can now be deleted from the Sidekiq web UI [#154]
Fix unnecessary shutdown delay due to Retry Poller [#174]

1.1.4

Add 24 hr expiry for basic keys set in Redis, to avoid any possible leaking.
Only register workers in Redis while working, to avoid lingering workers [#156]
Speed up shutdown significantly.

1.1.3

Better network error handling when fetching jobs from Redis. Sidekiq will retry once per second until it can re-establish a connection. (ryanlecompte)
capistrano recipe now uses bundle_cmd if set [#147]
handle multi_json API changes (sferik)

1.1.2

Fix double restart with cap deploy [#137]

1.1.1

Set procline for easy monitoring of Sidekiq status via "ps aux"
Fix race condition on shutdown [#134]
Fix hang with cap sidekiq:start [#131]

1.1.0

The Sidekiq license has switched from GPLv3 to LGPLv3!
Sidekiq::Client.push now returns whether the actual Redis operation succeeded or not. [#123]
Remove UniqueJobs from the default middleware chain. Its functionality, while useful, is unexpected for new Sidekiq users. You can re-enable it with the following config. Read #119 for more discussion.

Sidekiq.configure_client do |config|
  require 'sidekiq/middleware/client/unique_jobs'
  config.client_middleware do |chain|
    chain.add Sidekiq::Middleware::Client::UniqueJobs
  end
end
Sidekiq.configure_server do |config|
  require 'sidekiq/middleware/server/unique_jobs'
  config.server_middleware do |chain|
    chain.add Sidekiq::Middleware::Server::UniqueJobs
  end
end

1.0.0

Thanks to all Sidekiq users and contributors for helping me get to this big milestone!

Default concurrency on client-side to 5, not 25 so we don't create as many unused Redis connections, same as ActiveRecord's default pool size.
Ensure redis= is given a Hash or ConnectionPool.

0.11.2

Implement "safe shutdown". The messages for any workers that are still busy when we hit the TERM timeout will be requeued in Redis so the messages are not lost when the Sidekiq process exits. [#110]
Work around Celluloid's small 4kb stack limit [#115]
Add support for a custom Capistrano role to limit Sidekiq to a set of machines. [#113]

0.11.1

Fix fetch breaking retry when used with Redis namespaces. [#109]
Redis connection now just a plain ConnectionPool, not CP::Wrapper.
Capistrano initial deploy fix [#106]
Re-implemented weighted queues support (ryanlecompte)

0.11.0

Client-side API changes, added sidekiq_options for Sidekiq::Worker. As a side effect of this change, the client API works on Ruby 1.8. It's not officially supported but should work [#103]
NO POLL! Sidekiq no longer polls Redis, leading to lower network utilization and lower latency for message processing.
Add --version CLI option

0.10.1

Add details page for jobs in retry queue (jcoene)
Display relative timestamps in web interface (jcoene)
Capistrano fixes (hinrik, bensie)

0.10.0

Reworked capistrano recipe to make it more fault-tolerant [#94].
Automatic failure retry! Sidekiq will now save failed messages and retry them, with an exponential backoff, over about 20 days. Did a message fail to process? Just deploy a bug fix in the next few days and Sidekiq will retry the message eventually.

0.9.1

Fix missed deprecations, poor method name in web UI

0.9.0

Add -t option to configure the TERM shutdown timeout
TERM shutdown timeout is now configurable, defaults to 5 seconds.
USR1 signal now stops Sidekiq from accepting new work, capistrano sends USR1 at start of deploy and TERM at end of deploy giving workers the maximum amount of time to finish.
New Sidekiq::Web rack application available
Updated Sidekiq.redis API

0.8.0

Remove :namespace and :server CLI options (mperham)
