YAML: MRI does not load JRuby yaml files correctly (Problem is hash-key that start with zero)
---------------------------------------------------------------------------------------------
Key: JRUBY-4215
URL:
http://jira.codehaus.org/browse/JRUBY-4215 Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.4
Environment: Snow Leopard
Reporter: Thies C. Arntzen
in jirb:
>> {"0:1" => "0:1", "1:1" => "1:1"}.to_yaml
=> "--- \n\"1:1\": \"1:1\"\n0:1: 0:1\n"
>> YAML.load "--- \n\"1:1\": \"1:1\"\n0:1: 0:1\n"
=> {"0:1"=>"0:1", "1:1"=>"1:1"}
all is fine - see that the key 0:1 is not qouted in the generated YAML
if I try to load the jruby generated YAML in mri (ree 1.8.7) I don't get the 0:1 key back but instead just a 1:
>> YAML.load "--- \n\"1:1\": \"1:1\"\n0:1: 0:1\n"
=> {1=>1, "1:1"=>"1:1"}
If I serialize the original hash in mri mri will also quote the 0:1 hash index so it will load the YAML back correctly.
>> {"0:1" => "0:1", "1:1" => "1:1"}.to_yaml
=> "--- \n\"0:1\": \"0:1\"\n\"1:1\": \"1:1\"\n"
>> YAML.load "--- \n\"0:1\": \"0:1\"\n\"1:1\": \"1:1\"\n"
=> {"0:1"=>"0:1", "1:1"=>"1:1"}
I'm not sure if this is a bug in the mri ruby implementation or in jruby!
