script/server vs mongrel_rails start issue

rubyonrails-talk
1

I am having different results between when I start mongrel with script/ server and with mongrel_rails start.

When I run script/server to boot mongrel everything runs fine, no errors.

When I run mongrel_rails start I get the following errors - verified the problem on a fresh app and on two different environments (mac and yes, windows server 2008). The actual line of fault changes but the problem is always originating in /usr/local/bin/mongrel_rails:19

I would very much appreciate any ideas.

Hope this helps!

Thanks James - wondering if you also found that config.cache_classes = true caused problems? I found that the patch + changing this setting to false fixed things. config.cache_classes worked badly on 2.3.4 though also, so is a bit strange. As for the patch, I was finding that there was a nil value getting into the part of code where the patch is and that the .split was failing as it was coming in as nil.split. Strange. Was there a reason you stayed with 2.3.8 rather than just staying on an older version of rails?

Honestly we didn't really have a reason to upgrade to 2.3.8 besides trying to stay at the latest release. Since I figured out a way to get it to run I decided to keep going with 2.3.8. As for the cache_classes, I didn't experience any behavior like that.

Hi,

First of all, I'm sorry for my English.

Looks like I found the reason of this problem: I use REE 1.8.7, gem v=1.3.7 problem in ... /lib/ruby/site_ruby/1.8/rubygems/source_index.rb:89:in `read': can't convert Hash into Integer (TypeError)

because code

   if defined? Encoding then File.read file_name, :encoding => 'UTF-8'

will work only with ruby 1.9 you can find difference here Class: IO (Ruby 1.8.7) http://ruby-doc.org/ruby-1.9/classes/IO.html#M000125

I found that '(defined? Encoding) == true' because REXML::Encoding loaded

I found in my code this 'include REXML' removing this line helped to me fix this issue. Try to find in your code inclusion Namspace with Encoding constant
