Critical update of the loaders for Ruby 2.3 for Mac, Linux and FreeBSD

 If you are running encoded files on Mac, Linux or FreeBSD under Ruby 2.3, please update the loader. It's not necessary to re-encode the files, only update loaders. We fixed the issues with global variables for Ruby 2.3 and the above platforms. Windows (MinGW) loaders were not affected.

Loaders Update

We have released an update for RubyEncoder Loaders. This version of loaders includes the following fixes:

  • Fixed random segfault errors in loaders caused by the ruby garbage collector
  • Fixed problems running protected rails configuration scripts (see below)
  • Added support for Ruby-enterprise 1.8.6

Note: It is possible to encode and deploy rails configuration files usually stored in /config folder. You cannot encode *.yml database configuration script as it's not a ruby script. We suggest to use a cipher to encrypt this and load and decrypt it from the RubyEncoder protected code. So you will keep the key safe within the RubyProtected script.

Also you cannot have encoded /config/environments/*.rb scripts. Leave them unencoded. The reason for it is Rails internals. Rails loads the environment file dynamically and evaluates it with eval(). This will not work for protected scripts.

Updated loaders are available from our site http://rubyencoder.com/loaders.html
