In this file, this line
cd #{Daemons::Rails.configuration.root} && #{path} #{command} #{arguments unless argv.empty?}

Needs to be replaced by
cd "#{Daemons::Rails.configuration.root}" && "#{path}" #{command} #{arguments unless argv.empty?}

Given the following daemon

#!/usr/bin/env ruby

# You might want to change this
ENV["RAILS_ENV"] ||= "production"

root = File.expand_path(File.dirname(__FILE__))
root = File.dirname(root) until File.exists?(File.join(root, 'config'))
Dir.chdir(root)

require File.join(root, "config", "environment")

Rails.logger.info "Starting..."

$running = true
Signal.trap("TERM") do 
  $running = false
end

while($running) do

  # Replace this with your code
  Rails.logger.info "This daemon is still running at #{Time.now}.\n"

  sleep 10
end

Rails.logger.info "Ending..."

run with

rake daemon:test:start RAILS_ENV=development

and then stopped with

rake daemon:test:stop RAILS_ENV=development

the output is

test.rb: trying to stop process with pid 47042...
test.rb: process with pid 47042 won't stop, we forcefully kill it...
test.rb: process with pid 47042 successfully stopped.

and the log shows

Starting...
This daemon is still running at 2014-01-28 16:40:45 -0800.

This daemon is still running at 2014-01-28 16:40:55 -0800.

Ending...
Starting...
This daemon is still running at 2014-01-28 16:41:05 -0800.

This daemon is still running at 2014-01-28 16:41:15 -0800.

showing that the daemon restarted and then was killed.

Workaround:

Modify loop as follows:

while($running) do

  # Replace this with your code
  Rails.logger.info "This daemon is still running at #{Time.now}.\n"

  sleep 10
  unless $running
    raise 
  end
end

Raising an exception by-passes the restart.

If I run in the console with command (rake daemon:park) , I think the process run in foreground and does not exit but if I daemonize (rake daemon:park:start) it then it quits abruptly once it gets first connection request

Here is my code below.

Replace this with your code

s = UDPSocket.new
s.bind("0.0.0.0", 2000)
loop do
text, sender = s.recvfrom(16)
puts text
s.send "aaa", 0, sender[3], sender[1]
e = Event.find(1)
e.pdata = text
e.save
end

I have a Ruby on Rails app that depends on a number of daemons to work properly. It was working fine but I can't figure out what I changed to make it stop working. Now when I run the following command:

$ bundle exec rake daemons:start
I get the following error:

If it helps the only thing I suspect could have cause this was upgrading the the rails gem from version 4.1.25 to version 4.2.5 - but I'm not sure whether this could be the cause. How can I troubleshoot this.

Documentation states "All pids and logs will live in the normal log/ folder. This helps to make things Capistrano friendly.". The default location using Capistrano is tmp/pidsand not log/. Shouldn't this default location be changed to tmp/pids?

i.e.:

dir_mode: normal
dir: tmp/pids

When I call Daemons::Rails::Monitoring.statuses in development, it works fine, but on my production server, it returns not_exists even though the daemons are running.

error under 1.9.3

/Users/andrew/.rvm/gems/ruby-1.9.3-p327/gems/daemons-rails-1.1.0/lib/daemons/rails/configuration.rb:8:in `detect_root': uninitialized constant Daemons::Rails::Configuration::Pathname

i added the following to my _ctl script and it now works:

require 'pathname'
require 'fileutils'

@mirasrael I noticed the request for maintainers. Can you give a bit more information on where you need help with? We use this gem on our projects and would love to lend a hand and keep it up to date.

If it is simply a matter of fixing bugs, looks like the list is short. But I am assuming you have a longer work list that you have in mind that may not be captures in the issues list.

Thanks

$ rails generate daemon test

The error is due to auto_flushing no longer available in Rails 4, but that is another issue.

The result is you can only generate one daemon. You have to delete the lib/daemons directory to get it to generate another.

The generated _ctl scripts don't require 'bundler/setup' and so don't see gem files that bundler has downloaded that are not part of the main gem install.

I ran into this after setting up my Gemfile to use the git head version of daemons-rails (which rvm and bundler installed to /usr/local/rvm/gems/ruby-head@rails4/bundler/gems/daemons-rails-0bf7123eb5e6) rubygems doesn't pick that up if you don't include bundler.

The simple fix was to just add require 'bundler/setup' right after require 'rubygems'

Hello,
First of all i want to Say Thank You for this gem . I have been using it succesfully for a long time .
I recently saw You are looking for someone who can maintain the repository. I am interested in helping as much as i can. Let me know how can i help.

I would also appreciate If You could give me some pointers maybe in the right direcțion..about what You might have planned to implement or something that maybe You already started and i could help with the implementation.
Let me know if You will accept my help

Thank You very much.

Firstly, I love this gem - it's really handy.

I don't know if I'm doing something wrong, but I can't seem to run RSpec when I have the daemon in the lib/daemons folder. Rspec just stays frozen with no error message. It seems as if RSpec is actually running (or loading?) the daemon and stays in the endless loop of the daemon without proceeding to run any of the specs. If I move the daemons out of the lib folder, the specs run fine.

Thanks for your help!

Hi,

I would like to access active record from the daemon process and update the db records with the data I received from sockets.

Please throw some light on it.

Thanks.

I try using byebug to set breakpoints bug get *** No sourcefile available for my_listener.rb

Some companies will only use gems with a certain license.
The canonical and easy way to check is via the gemspec,

via e.g.

spec.license = 'MIT'
# or
spec.licenses = ['MIT', 'GPL-2']

Even for projects that already specify a license, including a license in your gemspec is a good practice, since it is easily
discoverable there without having to check the readme or for a license file. For example, it is the field that rubygems.org uses to display a gem's license.

For example, there is a License Finder gem to help companies ensure all gems they use
meet their licensing needs. This tool depends on license information being available in the gemspec. This is an important enough
issue that even Bundler now generates gems with a default 'MIT' license.

If you need help choosing a license (sorry, I haven't checked your readme or looked for a license file), github has created a license picker tool.

In case you're wondering how I found you and why I made this issue, it's because I'm collecting stats on gems (I was originally looking for download data) and decided to collect license metadata,too, and make issues for gemspecs not specifying a license as a public service :).

I hope you'll consider specifying a license in your gemspec. If not, please just close the issue and let me know. In either case, I'll follow up. Thanks!

p.s. I've written a blog post about this project
p.p.s. Here's a list of the license names I've found and their frequenceis

I'm using Rails 4 with Ruby 2.0. If I type:

rails generate daemon test

I get:

ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead.

Hello,

I have placed TCP server code in daemon as below, is it correct ?

while($running) do

Replace this with your code

require 'socket' # Get sockets from stdlib

server = TCPServer.open(8080) # Socket to listen on port 2000
loop { # Servers run forever
client = server.accept # Wait for a client to connect
data = client.recv(20)
data = client.recv(1024)
# data = data.split(" ")
# puts data.unpack('C*')
# client.puts "Closing the connection. Bye!"
client.puts data
client.close # Disconnect from the client
}

Rails.logger.auto_flushing = true
Rails.logger.info "This daemon is still running at #{Time.now}.\n"

sleep 10

end

Thanks.

Hi Mirasrael,

Thanks again for this gem, it makes daemon creating a cinch.

I'm finding that the dameon runs perfectly when in my environment (like development), config.cache_classes is set to false, but the daemon fails when config.cache_classes = true (such as in production).

Here is the out put in the daemon logfile:

I'm using Rails 3.0.1, and we're using Active Admin (just mentioning that because some active admin stuff is in the logfile).

Do you have any idea what could be affecting the daemon depending on what cache_classes is set to?

Thanks so much!

Could you please clarify the license for this project?

I am getting below error when I start daemon as "rake daemon:park:start" also my source code snippet is attached below.

Just installed this gem and I love what it does. Thank you for creating it. Using just the simple_daemon created by your generator, when I start the daemon everything is fine, logging every 10 seconds. But when I stop it (./lib/daemons/simple_daemon_ctl stop), it creates the log file log/simple_daemon.rb.log containing the errors:

The only change I made to the generated code was commenting out Rails.logger.auto_flushing = true because I use log4r. Everything seems to work, but it would be better not to have errors in the log file.

I'm using rvm, ruby 2.0.0p247, and Rails 4.0.0.

Hi Mirasrael,

Thanks for making this gem. I'm looking forward to getting daemons running in a rails 3.2.7 app.

A quick question (because I'm stumped)... when I try to start a simple daemon I made called newsletter_sender,

./lib/daemons/newsletter_sender_ctl start [FAILS]

I get the following error:

require: no such file to load -- daemons/rails/config (LoadError)

If I run the .rb file directly, it loads up my rails environment and does it's thing nicely. I can tail my development.log and see the daemon running, querying the database, etc.

./lib/daemons/newsletter_sender.rb [WORKS]

After a long time trying to learn how this error is happening, I'm thinking that for some reason, it's trying to load the normal daemons gem (1.1.8), which I have installed. That gem doesn't have the extra /rails/config or /rails.rb files et. al. that are required in the _ctl file.

Can you please help me figure out this issue? I'd very much appreciate learning why this is happening and how to fix it.

This is on a Rails 3.2.7 application.
I'm using rbenv with ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.2.0] in development, and
apache2/passenger ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux] in production.

Both environments are experiencing the same error.

Here is the contents of my newsletter_sender_ctl file:

#!/usr/bin/env ruby
require 'rubygems'
require "daemons"
require "daemons/rails/config"
require "daemons/rails"

root = Daemons::Rails.configuration.detect_root
config = Daemons::Rails::Config.new("newsletter_sender", root, Pathname.new(File.expand_path(__FILE__)).parent.relative_path_from(root))

Daemons.run File.dirname(__FILE__) + "/newsletter_sender.rb", config.to_hash

And the contents of my newsletter_sender.rb file:

#!/usr/bin/env ruby

ENV["RAILS_ENV"] ||= "development"

root = File.expand_path(File.dirname(__FILE__))
root = File.dirname(root) until File.exists?(File.join(root, 'config'))
require File.join(root, "config", "environment")

$running = true
Signal.trap("TERM") do 
  $running = false
end

while($running) do

    n = Newsletter.next_for_delivery

    if n
        n.deliver 
    else
        sleep 60
    end

end

I go to the root directory of my rails project and run

rake daemons:start --trace

and the response is

C:\JRuby\bin\rake: No such file or directory - lib/daemons/daemons

It is looking for lib/daemons/daemons from the C:\JRuby\bin\rake directory. Why? How can I specify my lib dir?

I have daemon with name "tasks_monitor".
It was starting fine but didn't want to stop with any of available commands.
Renaming to "tasks_executor" solved issue.

So, this is an undocumented feature or bug - daemons should have "_monitor" in their names.
