One of the readers commented that he was once in a situation where he had to propagate an exception from a destructor. But as a destructor cannot safely throw and it also cannot return any value, he needed a better solution. And that solution was std::exception_ptr. Let’s look into wh... C++26: constexpr virtual inheritance2026-07-01T00:00:00+02:00 2026-07-01T19:45:15+02:00 https://www.sandordargo.com/blog/2026/07/01/cpp26-constexpr-virtual-inheritance Sandor Dargo constexpr has come a long way since its introduction in C++11. Back then, constexpr functions were extremely restricted and could essentially contain only a single return statement. C++14 relaxed those restrictions, allowing local variables, loops, and multiple statements. C++20 was another major milestone, bringing support for constexpr dynamic allocation, enabling types such as std::string an... Trip report: ACCU On Sea 20262026-06-24T00:00:00+02:00 2026-06-24T00:00:00+02:00 https://www.sandordargo.com/blog/2026/06/24/trip-report-accu-on-sea-2026 Sandor Dargo Once again, I got the chance to come to Folkestone, UK. I think this was my fifth time, but the first one at ACCU On Sea. Yes, there is no more C++ On Sea, there is no more ACCU in Bristol — they got merged into ACCU On Sea. The venue is the same as C++ On Sea, many organisers are the same, but of course there are also changes. The conference chair is no longer Phil Nash but Guy Davidson. Th... Memory Management in C++ by Patrice Roy2026-06-17T00:00:00+02:00 2026-06-29T22:42:14+02:00 https://www.sandordargo.com/blog/2026/06/17/memory-managenent-by-patrice-roy Sandor Dargo Memory management is one of those topics that every C++ developer has to deal with, yet very few of us take the time to study it systematically. Memory Management in C++ by Patrice Roy is a book that finally gives this fundamental topic the deep and up-to-date treatment it deserves. It covers everything from the basics of how objects live in memory to modern techniques introduced as recently as... C++26: Cleaning up string literals2026-06-10T00:00:00+02:00 2026-06-29T22:42:14+02:00 https://www.sandordargo.com/blog/2026/06/10/cpp26-string-literals-cleaned-up Sandor Dargo The two papers we are covering today are complementary in a philosophical sense. They both improve how string literals are handled in C++26. P2361R6 tackles strings that are never evaluated — the ones that only exist at compile time. P1854R4 tackles evaluated string literals, making non-encodable characters ill-formed instead of implementation-defined. Let’s start with the unevaluated side. ...
