     [ https://issues.apache.org/jira/browse/THRIFT-2642?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jens Geyer updated THRIFT-2642:
-------------------------------
    Description: 
Recursive structs in 0.9.2 work fine in c++ & c#, but not in python, because generated code trying to use objects which not constructed yet.

Struct:
{code}
struct Recursive {
1: list<Recursive> Children
}
{code}

Python code:

{code}
class Recursive:
  thrift_spec = (
    None, # 0
    (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1
  )
{code}

Error message:

{code}
Traceback (most recent call last):
  File "ttypes.py", line 20, in <module>
    class Recursive:
  File "ttypes.py", line 28, in Recursive
    (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1
NameError: name 'Recursive' is not defined
{code}
