T Jake Luciani commented on THRIFT-807:
---------------------------------------
I took a look and I don't think this will work. We would need to initialize all
types to null including maps and arrays. I tried doing this and the test fails
since struct maps now aren't initialized.
I think we need to return null on an error, but haven't had a chance to see
where this would be possible in the generated code.
> JavaScript: Initialization of Base Types with 0 instead of null
> ---------------------------------------------------------------
>
> Key: THRIFT-807
> URL: https://issues.apache.org/jira/browse/THRIFT-807
> Project: Thrift
> Issue Type: Bug
> Components: Compiler (General)
> Affects Versions: 0.3
> Reporter: Roger Meier
> Attachments: THRIFT-807_initialize_with_null.patch
>
>
> I had a problem with the exception avaliable on the tutorial.
> i32 calculate(1:i32 logid, 2:Work w) throws (1:InvalidOperation ouch),
> It couldn't be thrown because initialization of numeric base types is done
> with 0 instead of null and the checks do compare against null.
> This was not visible with the Tests provided with first patch for JavaScript
> bindings above, the ThriftTest.thrift definition does not have a combination
> of a base type return value and an exception.
> I've made a patch that initializes the base types I16,I32, I64 and DOUBLE
> with null. This could probably solve other issues as well
> Regards
> Roger
