Breaks with multi_json 1.7.9 (works with 1.7.7)

[kylog]

With multi_json 1.7.9, running spec tests I get a backtrace like this:

/Users/kylo/devel/puppetk/.bundle/gems/ruby/1.8/gems/multi_json-1.7.9/lib/multi_json.rb:106:in `load_adapter': Did not recognize your adapter specification. (ArgumentError)

Hey @kylog - I have been unable to reproduce this. I've tested on MRI 1.9.3-p484 / multi_json 1.7.9 with Oj / Yajl / JSON / bson individually, as well as JRuby 1.7.9 with JrJackson, which should cover all of the default adapters used by MultiJson. Could you share what JSON gems you are loading, or if you perform any multi_json initialization before loading the json-schema gem?

@hoxworth My bad, not enough details in the original report.

• I only see this with 1.8.7-p371 (which is the only 1.8.7 I've tried; it may apply to 1.8.x).
• I'm using the json backend, and I'm not doing any multi_json initialization.

E.g.

irb(main):001:0> RUBY_VERSION
=> "1.8.7"
irb(main):002:0> require 'json'
=> true
irb(main):003:0> require 'multi_json'
=> true
irb(main):004:0> require 'json-schema'
ArgumentError: Did not recognize your adapter specification.

Thanks! I'll clean this up tomorrow along with some other related fixes.

I'm assuming this is working now, partly based on @hoxworth's comments and partly because the test suit is now testing Ruby 1.8 (kind of) and multi_json
