-----------------------------------
Summary: C++ generator should topologically sort struct
definitions and error on cycles
Key: THRIFT-4846
URL: https://issues.apache.org/jira/browse/THRIFT-4846
Project: Thrift
Issue Type: Bug
Reporter: Todd Lipcon
C++ (and maybe other languages?) treat Thrift struct-typed fields as plain
struct members of the containing struct. Currently, the generator outputs the
types in the same order as they're defined in the underlying Thrift field,
which means that a file like:
{code}
struct A {
1: B foo;
}
struct B {
}
{code}
will generate C++ code that fails to compile.
We should topologically-sort the structs before outputting the definitions so
that the generated code compiles correctly.
