Supervise fails with Celluloid 0.17

[OndroNR]

With Celluloid 0.17.0 this sample code with supervise (simple HTTP.run works) fails (works with Celluloid 0.16):

require 'celluloid/autostart'
require 'reel'

supervisor = Reel::Server::HTTP.supervise('127.0.0.1', 3000) do |connection|
  connection.each_request do |request|
    request.respond :ok, "hello, world!"
  end
end

begin
  sleep
rescue Interrupt
  supervisor.terminate
end

with following log:

Ah, this is a bad behavior of the backported code.

Changing that to this will work for now:

Reel::Server::HTTP.supervise(args:['127.0.0.1', 3000])

[OndroNR]

Thanks for reply, but it doesn't work for me. Same error.

[digitalextremist]

Do you have any other Celluloid related code in your project? If not, change to:

require 'celluloid/current'

I'll look at this some more in the meantime.

In 0.16 this works as expected:

require 'celluloid/autostart'
require 'reel'
Reel::Server::HTTP.supervise("0.0.0.0", 3001) do |connection|
  raise if [false, true].sample
  connection.each_request do |request|
      request.respond :ok, "Hello, world!"
  end
end

however in 0.17.2 this won't restart after crash:

require 'celluloid/current'
require 'reel'
Reel::Server::HTTP.supervise({args: ["0.0.0.0", 3001]}) do |connection|
  raise if [false, true].sample
  connection.each_request do |request|
      request.respond :ok, "Hello, world!"
  end
end
