Norms methods
by General Magic - Teodora Bogdan 26 Oct '22

Hello, I was using the Boost library and I wanted to call the l2_norm() method from "boost/math/tools/norms.hpp", but is says that the namespace boost::math::tools doesn't contain l2_norm() method. When I looked into it, I saw that the namespaces at the beginning of the file were written"boost::math::tools" instead of "namespace boost { namespace math { namespace tools {...". Can this be fixed?

Boost::serialization detection of Cxx Standard
by Georg Gast 14 Oct '22

14 Oct '22

Hi, I developed a patch and a test to serialize std::pmr::(w)strings in all 3 archive types. The test I set the requirement to <cxxstd>17. It works so far but when I compile the library for using it in my application the "hidden" functions behind "BOOST_NO_CXX17_MEMORY_RESOURCE" are not found by the linker as the define is set when the library is compiled. How to work around this? Bye Georg

Is there any official documentation on shutdown procedure for ASIO SSL socket?
by Ivan Matek 11 Oct '22

There is this SO answer https://stackoverflow.com/a/25703699/ with Vinnie comment from 8y ago that it should be added to documentation. :) I can not find anything in the documentation so I presume the documentation/example does not exist, but I decided to double check. regards, Ivan

Very slow destructors of binary_oarchive and filtering_streambuf
by boost.5nyej＠simplelogin.com 03 Oct '22

03 Oct '22

Hello, I just posted a question on StackOverflow, but I realised that this mailing list might be a better place. The link to the question is: https://stackoverflow.com/questions/73938656/very-slow-destructors-of-binar… Tl;dr; I have a code that serializes a big object by using binary_oarchive and filtering_bufstream. The writing on its own takes around 28 minutes, but the deconstructors of the mentioned classes take 37 and 36 minutes, respectively. It is very strange to me that they would take so much time to run, as the first deconstructor adds only 2KiB of data, and the second deconstructor doesn't change anything. Could you help me find the root cause of those execution times?
