TAO Exceptions based on std::exception

[tstaig]

I was discussing with some people at our project and we noticed that the latest official C++ mapping document 1 states that the Exception class (defined in TAO/tao/Exception.h) should extend the std::exception class.

So I wanted to ask why haven't ACE/TAO adopted this mapping standard? Is it just because there are more pressing matters? Or there are consequences such as marshalling/unmarshalling issues o performance hit?

Thanks!

You refer to the IDL to C++11 language mapping (see https://www.omg.org/spec/CPP11) which is supported by TAOX11, see https://www.taox11.org. TAOX11 is an extension of TAO which implements this new mapping, TAO itself uses the IDL to C++ mapping, see https://www.omg.org/spec/CPP

Thanks @jwillemsen for your answer, I was unaware there was a separate TAO project for C++11 mappings. I presume there will be several other changes that could impact a migration, but we will study this possibility.

The IDL to C++11 language mapping is much easier and safer to use, but you have to migrate your code, mostly a find/replace effort, the compiler will tell you where you have to change things.
