Làm thế nào để cài đặt SystemTimer trên 1.9.2?

Question

Tôi vừa mới nâng cấp ứng dụng của mình từ 1.8.7 lên 1.9.2 bằng RVM và phải thêm RubyGems và Bundler, chạy gói cài đặt và có mọi thứ để làm việc ngoại trừ SystemTimer. Google-fu không trả lại gì và tôi thấy những người khác đã gặp vấn đề với nó trong phiên bản 1.9 nhưng một số đã khiến nó hoạt động. Bất kỳ ý tưởng?

Answer 1

Theo như tôi biết, SystemTimer không liên quan đến ruby ​​1.9 và không nên sử dụng với phiên bản này.

"Sử dụng đá quý này trong Ruby 1.9 là vô dụng và không có ý nghĩa gì! Hệ thống hẹn giờ đang cố gắng làm việc xung quanh một số giới hạn của mô hình" sợi xanh "được sử dụng trong Ruby 1.8 (MRI) Xem http://ph7spot.com/musings/system-timer để biết thêm chi tiết. "

Answer 2

Để cài đặt hệ thống hẹn giờ sử dụng lệnh này trong Terminal:

sudo gem install system_timer 

Answer 3

Một thay thế thả-in cho SystemTimer là timeout.rb từ Ruby lõi. Không cần bất kỳ đá quý bên thứ 3 nào.

Ruby 1,8:

require 'system_timer' 

SystemTimer.timeout_after(5.minutes, MyException) do 
    # your job here 
end 

của Ruby 1.9:

require 'timeout' 

Timeout.timeout(5.minutes, MyException) do 
    # your job here 
end
