Safe execution environment for untrusted ruby code.

gem install sicuro

Sicuro safely executes untrusted ruby code without any complex configuration, unjustifiable permissions (such as passwordless sudo), or chroots/BSD Jails.

It returns both STDOUT and STDERR as a single string. In the future, it may offer a method that returns [stdout, stderr] instead.

The preferred option is to run code using the default limits. These are being tweaked so they are (hopefully) sane on any system capable of running ruby.

require 'sicuro'

Sicuro.eval('puts "hi!"') # returns "hi!\n"

You may, optionally, specify a timelimit and memory limit.

The following example shows what I would like the defaults to be, but something seems to like eating RAM when I'm not looking.

require 'sicuro'

timelimit = 5
memlimit  = 10

Sicuro.setup(timelimit, memlimit)
Sicuro.eval('puts "hi!"') # returns "hi!\n"
