Subject: Systemd socket inheritance fails with “not a socket file descriptor”
Date: Tue, 08 Mar 2016 01:08:51 +0200	[thread overview]
Message-ID: <1457392131.48974.542407130.6981D79B@webmail.messagingengine.com> (raw)

Hi,
 
I have yet to compile a minimal failing configuration, but posting here
in case it’s a common problem.
 
Starting the systemd service with a configuration based on
http://bogomips.org/unicorn-public/20150708130821.GA1361@luke.ws.skroutz.gr/
(also found under examples/ in the source code), it fails, and the
following is seen in the systemd journal:
 
> app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/lib/unicorn/http_server.rb:780:in `for_fd': not a socket file descriptor (ArgumentError)
> from app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/lib/unicorn/http_server.rb:780:in `block in inherit_listeners!'
> from app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/lib/unicorn/http_server.rb:779:in `map!'
> from app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/lib/unicorn/http_server.rb:779:in `inherit_listeners!'
> from app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/lib/unicorn/http_server.rb:111:in `start'
> from app/vendor/bundle/ruby/2.0.0/gems/unicorn-5.0.1/bin/unicorn:126:in `<top (required)>'
> from app/vendor/bundle/ruby/2.0.0/bin/unicorn:23:in `load'
> from app/vendor/bundle/ruby/2.0.0/bin/unicorn:23:in `<main>'
 
The error, in `for_fd': not a socket file descriptor (ArgumentError),
occurs when attempting `io = Socket.for_fd(fd.to_i)`.
 
Using Ruby version 2.0.0p645.  Should I try using 2.2 or later?
 
Thanks,
Amir
