Once again it has been a busy few months working on libraries in different stages of the boost lifecycle: Libraries for Proposal Decimal Decimal (https://github.com/cppalliance/decimal) is a ground-up implementation of the IEEE 754 Decimal Floating Point types in C++14, and is co-authored by Chris Kormanyos. The past few months we have worked hard to squeeze more performance out of the library, and we believe we have successfully accomplished that. By request we have also added functions ...

Easy client-side SQL using with_params In previous posts, we had seen how Boost.MySQL client-side SQL formatting can be used to implement a wide variety of use cases. It was originally created for complex cases, like batch inserts, but it can also be applied for simple ones. Up to Boost 1.86, to retrieve a user by ID with client-side SQL, you could write this: void lookup(mysql::any_connection& conn, int id) { // Compose the query. May generate "SELECT * FROM user WHERE id = 10" ...

The Safe C++ Saga I’ve spent the last quarter developing a successor to the C++ stdlib in Safe C++, the proposal from Sean Baxter to add borrow-checking semantics to C++. I’ve been an avid Rust fan since I started messing around with it in my spare time a few years ago so hopping on this project was an incredibly exciting opportunity. Getting to evolve a standard library in tandem with a language that attempts to do the nigh-on-impossible is a once-in-a-lifetime opportunity, really. Public...

During Q3 2024, I’ve been working in the following areas: Boost.Unordered Made visitation exclusive-locked within certain boost::concurrent_flat_set operations to allow for safe mutable modification of elements (PR#265, to be released in Boost 1.87.0). This is relevant for the work on Boost.Flyweight discussed below. Added new concurrent, node-based containers boost::concurrent_node_map and boost::concurrent_node_set (PR#271, to be released in Boost 1.87.0). These containers are, expec...

Safe C++ Partnership I am happy to announce that the C++ Alliance has formed a partnership with Sean Baxter, a renowned engineer, to develop the Safe C++ Extensions proposal. This is a revolutionary proposal that adds memory safety features to the C++ programming language. This collaboration marks a significant milestone in the C++ ecosystem, as the need for safe code has never been more pressing. With the increasing importance of software security and reliability, developers are facing mo...
