Jens Geyer commented on THRIFT-5067:
------------------------------------

May I ask to also add a small IDL to illustrate the exact problem and to be used as a test case?

> I classify this as a bug as valid Thrift file silently generates invalid C++ code. Feel free to change the issue type if you disagree.
> I use a a namespace hierarchy for my Thrift data model. When writing nested namespaces, I tend to represent to parent-child relationship of these namespaces in their the containing file names.
> So for example, I have the following relationship:
>  * namespace "base" defined in file "base.thrift"
>  * name "base.net" defined in file "base.net.thrift"
> Note that this convention of using dots to separate namespaces seems consistent with Thrift namespace syntax.
> The generated Cpp header for the base.net namespace does not compile: the include guard variable name uses the dot which is not valid C++ syntax.
> I think the Cpp compiler should replace dots with underscores when generating the include guard.
