[any] [basic_any] This seems like a little pearl in Boost 1.77, but it's a bit underdocumented?
by Viktor Sehr 21 Sep '21

I just discovered basic_any which is a very nice addition for me. However it's a bit under-documented for the moment. For example: - I assume it's stack-allocated, does it allocate on the heap if assigned an object larger than the stack (like small_vector) or is this not allowed (like static_vector)? - An idea would also be to add a flag which breaks compilation if an object larger than the OptimizeForSize argument is assigned? - (For detail) If allocated on the stack, are the first bytes of the basic_any the same as the contained object? /Viktor

[ICL] Proposal to support other set/map implementations
by Martin Duvanel 18 Sep '21

18 Sep '21

Hello, We are using boost::icl::interval_set with very large amounts of intervals, and we are having some performance issues. Profiling showed that, in our use-case, a lot of time was spent on memory allocation/deallocation, and swapping std::set for boost::flat_set made a huge, positive difference. We may have a very specific use-case, but would you consider a small modification to the library inside "boost/icl/impl_config.hpp", in order to open the door for other set/map implementations? Here is the simple change we made to "boost/icl/impl_config.hpp" for this experiment: <code> #if defined(ICL_USE_BOOST_MOVE_IMPLEMENTATION) # define ICL_IMPL_SPACE boost::container #elif defined(ICL_USE_STD_IMPLEMENTATION) # define ICL_IMPL_SPACE std + #elif defined(ICL_USE_CUSTOM_IMPLEMENTATION) + # define ICL_IMPL_SPACE ICL_CUSTOM_IMPL_SPACE #else # define ICL_IMPL_SPACE std #endif </code> And then declaring the following before including: <code> namespace custom_icl { template <class Key, class T, class Compare, class Allocator> using map = boost::container::flat_map<Key, T, Compare, Allocator>; template <class Key, class Compare, class Allocator> using set = boost::container::flat_set<Key, Compare, Allocator>; } // namespace custom_icl #define ICL_USE_CUSTOM_IMPLEMENTATION 1 #define ICL_CUSTOM_IMPL_SPACE custom_icl </code> Would such a change make sense in your opinion? If that's the case, then I would be happy to participate in the contribution. Thank you and best regards, Martin Duvanel

16th Google Summer of Code Participation
by Cem Bassoy 15 Sep '21

15 Sep '21

Since 16 years, the Boost foundation has been selected as a mentor organization by the Google Summer of Code <https://summerofcode.withgoogle.com/> committee. If I am not mistaken, Boost has mentored over 100 students who contributed to existing and experimental boost libraries. This year, 8 students successfully contributed to Boost.Real, Boost.Gil, Boost.Math, Boost.Python, Boost.uBlas, Boost.Multiprecision, see project descriptions <https://summerofcode.withgoogle.com/organizations/6722937052200960/#projects> . Here <https://opensource.googleblog.com/2021/06/google-summer-of-code-2021-studen…> are some stats about GSoC21. I would like to thank all students for their contribution and all mentors who have made this possible. Keep up the good work! All the best, Cem

Head to Github and check out the issues on all the libraries. Fork, fix, and submit pull requests. <https://svn.boost.org/trac10/wiki/StartModPatchAndPullReq> (I don't see anything here about legal issues. Does one need to file a contributor release?)

Hi Team, Please help me for below query. What are the steps we need to do to include boost in to our code base and release bour software without any obligation? Ex: include license along with our binaries or we need to publish our code to boost platform....? Are we oblige to share anything to boost? Regards, Rajesh D

Can we create boost-config
by Sreeraj K 06 Sep '21

06 Sep '21

*[I initialially raised this question in https://github.com/boostorg/boost/issues/548 <https://github.com/boostorg/boost/issues/548>, but @mclaw recommended this mailing list.]* Similar to many other packages (eg: curl, krb5, pcre, xml2, xslt etc..), can we also ship boost-config that would provide the installation options ? We can probably start with something like this ? $ /usr/bin/boost-config --help Usage: boost-config [ options ] Options: --cflags print compiler options --ldflags print linker options --prefix print the boost prefix --version print the boost version --help print this usage summary $ /usr/bin/boost-config --version 1.66.0 $ /usr/bin/boost-config --cflags -I/usr/include $ /usr/bin/boost-config --ldflags -L/usr/lib64 -Wl,-R/usr/lib64 Thanks.
