julien greard edited comment on THRIFT-2642 at 5/13/15 7:42 AM: ---------------------------------------------------------------- I did my own work around: in the example above, I replaced the code: class Recursive: thrift_spec = ( None, # 0 (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1 ) by (sorry for the bad indent, I don't know how to have a nice display) {code} class Recursive: pass Recursive.thrift_spec = None depth = 0 max_depth = 50 while (depth < max_depth): depth += 1 Recursive. thrift_spec = ( None, # 0 (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1 ) {code} Which seems to do the job... It's ugly because I have to edit the generated code afterward, but I didn't want to touch at the code generator in Thrift code... what do you think ? was (Author: juliengreard): I did my own work around: in the example above, I replaced the code: class Recursive: thrift_spec = ( None, # 0 (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1 ) by (sorry for the bad indent, I don't know how to have a nice display) class Recursive: pass Recursive.thrift_spec = None depth = 0 max_depth = 50 while (depth < max_depth): depth += 1 Recursive. thrift_spec = ( None, # 0 (1, TType.LIST, 'Children', (TType.STRUCT,(Recursive, Recursive.thrift_spec)), None, ), # 1 ) Which seems to do the job...
