Don't get me wrong. I don't think memory management in C++ is worse than in pure C. It just does not bring enough benefits compared to C to justify the transition of such a big existing project like SVN, especially if you consider the broad range of (partially ancient) platforms and compilers which need to be supported. Well-designed Smart Pointers will actually solve a lot of problems of memory management, but it is hard to find a fully portable solution which comes without side-effects. (Boost is bloaty, C++ 11 not yet supported on most of the platforms, ...). Additionally, all the public SVN interface, as well as some used libraries (APR) rely on the current pool-based management. It would be hard to replace that while still remaining compatible. For SVN 2.0, if C++ 11 is widespread enough by then, I'd not oppose going to C++, or even to a completely different beast like Rust, Go or Python. :-) Best regards Markus Schaber CODESYS(r) a trademark of 3S-Smart Software Solutions GmbH Inspiring Automation Solutions 3S-Smart Software Solutions GmbH Dipl.-Inf.
