running unicorn under rvm

running unicorn under rvm

[Joseph McDonald]

unicorn 1.1.2 runs fine under my system ruby, but when trying to run
it using rvm, I get:


% rvm use 1.8.7
info: Using ruby 1.8.7 p299

% unicorn
/home/joe/.rvm/gems/ruby-1.8.7-p299/gems/unicorn-1.1.2/lib/unicorn/configurator.rb:494:in
`eval': undefined local variable or method `host' for main:Object
(NameError)

line 494 looks like:

 # XXX ugly as hell, WILL FIX in 2.x (along with Rainbows!/Zbatery)
    host, port, set_listener, options, daemonize =
                    eval("[ host, port, set_listener, options, daemonize ]",
                         TOPLEVEL_BINDING)

any ideas why it would have a problem when running under rvm?

thanks,
-joe

Hi Joseph,

Is there any chance you have an older "unicorn" executable script
somewhere that gets exposed rvm switches the environment on you?  That's
the only thing I can think of right now.

Yes, I still need to work on 2.x and clean up a lot of the
ugly internal API bits :)

P.S.: At least nowadays I'm (finally) getting some experience
developing/supporting applications using Unicorn and Rainbows! (or
Zbatery).  Things like e4d0b226391948ef433f1d0135814315e4c48535 in
unicorn.git are a direct result of that.

I'm sure I'm running the right version of unicorn.
what's weird is if I remove the reference to TOPLEVEL_BINDING, it works, i.e.:

 host, port, set_listener, options, daemonize =
                    eval("[ host, port, set_listener, options, daemonize ]")

works, it gets the right port from the config.ru file.

my config.ru file looks like"
#\ -w -p 4452
require './mystuff'
run Sinatra::Application

another strange thing:  I need to add the "./"  in front of mystuff,
but when i'm not using rvm (rvm use system), I don't need to do that.

I'm curious if anyone else is using unicorn with rvm and not having
this problem.  I'm guessing it's something weird with my system, but
not sure.

thanks,
-joe

Hm... I'm stumped.  However, you're really encouraging me to pause other
projects, work on 2.0 and release it this week/weekend :)  I suppose
some of the crazier 2.0 stuff I proposed can wait until 3.x.

Odd... needing the './' feels like it's using Ruby 1.9.2 or later...
Can you print out RUBY_VERSION in there to be certain?

I just tried rvm for the first time with a fresh user/home directory on my
system and everything works as expected with 1.8.7 (it just picked p302, not
p299, but that shouldn't make a difference...).

If you have root on your machine, just try creating a new user and start
with a blank $HOME.  I often do that to narrow things down when
debugging/testing code and don't feel like going all the way with chroot
or VM.

Re: running unicorn under rvm

I added
TOPLEVEL_BINDING = binding
to gems/unicorn-1.1.2/bin/unicorn
and it seemed to fix it:

#!/this/will/be/overwritten/or/wrapped/anyways/do/not/worry/ruby
# -*- encoding: binary -*-
require 'unicorn/launcher'
require 'optparse'
# !!!!!!!!!  added the line below:
TOPLEVEL_BINDING = binding
ENV["RACK_ENV"] ||= "development"

I still have no idea why I need to do that.

thanks,
-joe
