Passenger 3.0 and debugger

I have problems using passenger standalone with a debugger. If I try this:

passenger start --debugger

I get this error:

Your version of ruby-debug is too old. Please upgrade to the latest version.

My Ruby is: ruby 1.8.7 (2010-04-19 patchlevel 253) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2010.02

Ruby debug: ruby-debug (0.10.3) ruby-debug-base (0.10.3)

So, has anyone successfully used Passenger 3.0 with a debugger?

I got stumped by this issue too. I was going to mention that you have to use ruby-debug19, as someone had mentioned to me, but I see you're not using ruby 1.9.2 so that doesn't apply. Assuming you're on rails3 is ruby-debug listed in your Gemfile? – Jeremy

It isn't supposed to work, the flag was experimental but we forgot to remove it for 3.0.0, that's why it isn't documented. It'll be removed for 3.0.1.

You can run a debugger in Passenger by using rack-debug

It works by having a client connect to the Passenger process at the breakpoints you set. A bit more complicated than using Thing/Mongrel with a debugger. But pretty simple to setup.
