Сегодня попался рельсовый код, в котором используются монады, сервисы и прочее. Решил сделать обзор с объяснением того, что в коде не нравится и что можно исправить.

Данный разбор основан только на личном опыте и избегает попытку написать самый идеальный код на свете. К сожалению пошарить ссылку на код не могу, потому что автор попросил опубликовать анонимно.

Главная операция, которая вызывается из контроллера выглядит следующим образом:

# FOR BUSY JOBS
# take the process_id from the /busy page in sidekiq and kill the longest running one.
workers = Sidekiq::Workers.new
long_process_id = 'integration.3:4:71111aaa111' # Eg: 'integration.3:4:71d1d7f4ef5a'
workers.each do |process_id, thread_id, work|
  process = Sidekiq::Process.new('identity' => process_id)
  process.stop! if process_id == long_process_id
end

Example: Moving up to a few commits to another branch

Branch A has commits (X,Y) that also need to be in Branch B. The cherry-pick operations should be done in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y
