FixNum related error for pooling.rb

[charliebabbitt1988]

Blue Hydra won't launch with Ruby 3.2.3. Here is what I see in the blue_hydra.log file:

I'm not sure if you can re-produce this, but this is occurring on a brand new Ubuntu 24.04 LTS desktop install.

"ruby -v" shows this: ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x86_64-linux-gnu]

I'm not sure how to address this one as it seems to be a Ruby issue. From what I have been able to gather, the use of "FixNum" has been deprecated since Ruby 2.4 and "Integer" has replaced "FixNum" and "BigNum".

I could "patch" the pooling.rb file to use "Integer" instead of "FixNum", but that doesn't seem like a good long term solution.

Edited: I was able to work around this by editing the /var/lib/gems/3.2.0/gems/data_objects-0.10.17/lib/data_objects/pooling.rb file and changing line 149 to use "Integer" instead of "FixNum". Blue Hydra now launches and runs successfully.

This is the line now (starting at line 148):

      def initialize(max_size, resource, args)
         raise ArgumentError.new("+max_size+ should be a Integer but was #{max_size.inspect}") unless Integer === max_size
         raise ArgumentError.new("+resource+ should be a Class but was #{resource.inspect}") unless Class === resource

So this seems to be a Ruby gem issue with Ruby 3.2. Maybe a bug report should be filed to the Ruby developers?
