Fokko commented on issue #345:  AVRO-1256: C++ API compileJsonSchema ignores 
"doc" and custom attributes on a field/record
URL: https://github.com/apache/avro/pull/345#issuecomment-437336593
 
 
   Asked @thiru-apache to check if he can fix the tests. The rebasing on master 
was required to trigger the CI. But the cpp tests aren't running at all: 
https://github.com/apache/avro/blob/master/build.sh#L53-L70
   
   Do you see an opportunity to enable and fix the tests @aniket486 ?

> It appears that when my JSON is compiled into a valid schema object it is 
> ignoring all types of "documentation" that I am trying to adorn with each 
> field in my record. Reading through the Java issues it seems that this was a 
> bug and fixed (AVRO-601, AVRO-612, AVRO-779) but it seems the C++ 
> implementation has yet to adopt this feature? This is my sample schema, I 
> have attempted to insert both "doc" and "mycustom" in multiple places to see 
> if it is supported at any level. Please excuse if there appears to be a 
> syntax error in the JSON I hand tweaked some of this. The schema is valid and 
> successfully parses.
> {
>       "type": "record",
>       "name": "myschema",
>       "doc": "Doc Meta",
>       "mycustom": "My Custom",
>       "fields": [
>               { "name":"field_a","type":["string","null"], "doc":"Doc Meta", 
> "mycustom":"My Custom A"},
>               { "name":"field_b","type":["string","null"], "doc":"Doc Meta", 
> "mycustom":"My Custom B"},
>               { "name":"field_c","type":["string","null"], "doc":"Doc Meta", 
> "mycustom":"My Custom C"}
>       ]
> }
> I looked through the SchemaTests.cc code for 1.7.3 and there was not a test 
> case for this there so i didn't think this was addressed in that version. I 
> am running 1.7.2. When this schema is used to load with compileJsonSchema and 
> then a file is serialized the file schema looks like this.
