Moving sp_thread_pause, sp_thread_sleep to Core
by Christian Mazakas 02 Jun '23

02 Jun '23

Unordered's concurrent flat map contains a hand-rolled spinlock (graciously provided by Peter Dimov) but it contains a dependency on SmartPtr for the following two headers: #include <boost/smart_ptr/detail/sp_thread_pause.hpp> #include <boost/smart_ptr/detail/sp_thread_sleep.hpp> I advocate that we move these to Core. They're small, self-contained and are useful in broader contexts. Anyone have thoughts or objections? - Christian

git hub discussions.

As an experiment, I've added to github discussions for the safe_numerics library. The idea is to provide a place for feedback from users of the library. I'd be curious to hear other persons thoughts on this. https://github.com/boostorg/safe_numerics/discussions/133 Robert Ramey

The suggested repository is now ready for light review at https://github.com/boostorg/compat, complete with its first component, an implementation of std::latch by Christian Mazakas. Everyone's light reviews are welcome.

Sam review scheduled
by Ruben Perez 20 May '23

20 May '23

Hi all, I'm happy to announce that the Sam library, featuring asio-based synchronization primitives, is being proposed for Boost inclusion. Repo: https://github.com/klemens-morgenstern/sam Docs: https://klemens.dev/sam/ The library is being proposed by Klemens Morgenstern. The review will take place between May the 29th (Monday) and June the 8th (Thursday). I will be managing the review. Boost.Sam offers async asio-based synchronization primitives, similar to standard mutex, condition_variable, semaphore and barrier. It's geared towards library writers that require fine-grain control over their synchronization operations. You can contact both me and the author by mail or on the cpplang Slack. Kind regards, Ruben.

Regex is now header only, *unless* you are building with a C++03 compiler (which is now deprecated), and will require linking to the external libboost_regex. John.

That depends exactly what you mean by that, but you're likely looking for something like: my_socket.remote_endpoint().address().is_v6() Doxygen doesn't do a very good job at navigating the type templates involved here; using your IDE's code completion is more successful.

Reference section of Boost.Any leads to Boost.PFR

Hi, Just noted that clicking on "->" arrow at the developer preview of Boost.Any https://www.boost.org/doc/libs/develop/doc/html/any/ValueType.html leads to Boost.PFR reference section. No idea how is that possible. I'd appreciate help

Hi All, Recently we upgraded to Boost 1.82.0. We compiled the boost as : ./bootstrap.sh --with-libraries=filesystem,system,program_options,iostreams,log,regex,stacktrace,thread --without-icu When we tried to use the regex library and build Avro product we are getting following error: Boost/boost_1_82_0/include/boost/regex/v4/cpp_regex_traits.hpp:1117: undefined reference to `boost::scoped_static_mutex_lock::scoped_static_mutex_lock(boost::static_mutex&, bool)' Please can you help us in addressing the issue. Thanks and Regards, Prabhakar

Determine socket is ipv4 or ipv6
by Tarun Batra 14 May '23

14 May '23

Hi, I have a code something like this: TcpConnection::pointer my_conn = GetConn(req); tcp::socket& my_socket = my_conn->getSocket(); tcp::resolver my_resolver(my_socket.get_executor()); Is it possible to check if the my_socket is ipv4 socket or ipv6 socket?
