== Installation

Add this line to your application's Gemfile:

$ bundle add sidekiq-antidote

Or install it yourself as:

$ gem install sidekiq-antidote

== Usage

[source, ruby]

require "sidekiq" require "sidekiq/antidote"

Sidekiq::Antidote.configure do |config|

Set inhibitors cache refresh rate in seconds.

Default: 5.0

config.refresh_rate = 10.0 end

When running in forked environment (e.g., Puma web server), you also need to call Sidekiq::Antidote.startup on fork:

[source, ruby]

file: config/puma.rb

on_worker_boot { Sidekiq::Antidote.startup }

=== Web UI

Adding Antidote tab in Sidekiq web UI is as simple as:

[source, ruby]

require "sidekiq/web" require "sidekiq/antidote/web"

=== Middleware(s)

Sidekiq::Antidote relies on following bundled middlewares:

• Sidekiq::Antidote::Middlewares::Client
• Sidekiq::Antidote::Middlewares::Server

The middleware is automatically injected when you require sidekiq/antidote. In rare cases, when this causes an issue, you can change middleware order manually:

[source,ruby]

Sidekiq.configure_client do |config|

...

config.client_middleware do |chain| chain.prepend(Sidekiq::Antidote::Middlewares::Client) end end

Sidekiq.configure_server do |config|

...

config.client_middleware do |chain| chain.prepend(Sidekiq::Antidote::Middlewares::Client) end

config.server_middleware do |chain| chain.prepend(Sidekiq::Antidote::Middlewares::Server) end end

See: https://github.com/sidekiq/sidekiq/blob/main/lib/sidekiq/middleware/chain.rb

== Inhibitors

=== Treatments

When adding antidote you must pick on of the treatments:

skip:: Skip the job (don't enqueue and/or perform) kill:: Kill the job (send to the dead set instead of enqueueing and/or performing)

=== Class Qualifiers

Class qualifier is the job class pattern. It may match the job class or the job class and method name (when used with ActionMailer delayed deliveries):

• ExampleJob
• Namespaced::ExampleJob
• UserMailer#welcome

You can also use pattern matching:

*:: Matches any number of alpha-numeric characters and underscores:

• *Job matches: ExampleJob, but not Namespaced::ExampleJob, or UserMailer#welcome
• UserMailer#* matches any method of UserMailer **:: Matches any number of components:
• ** mathes any job or mailer method
• A::**::Job matches A::B::Job, A::B::C::D::CJob, etc.
• A**::Job matches A::Job, Abc::Job, A::B::Job, etc. {}:: Matches any of the given literal:
• {A,B,C}Job matches AJob, BJob, and CJob

== Compatibility

This library aims to support and is tested against:

• https://www.ruby-lang.org[Ruby] ** MRI 3.0.x ** MRI 3.1.x ** MRI 3.2.x ** MRI 3.3.x
• https://github.com/sidekiq/sidekiq[Sidekiq] ** 7.2.x ** 7.3.x
• https://redis.io[Redis] ** 6.2.x ** 7.0.x ** 7.2.x

If something doesn't work on one of these versions, it's a bug.

This library may inadvertently work (or seem to work) on other Ruby, Redis, and Sidekiq versions, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby, Redis, or Sidekiq version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby, Redis, and/or Sidekiq version may be dropped.
