[lightweight_test] cpp_main convention
by Mateusz Loskot 25 Mar '20

25 Mar '20

Hi, I noticed this as popular convention across Boost libraries (e.g. endian) to deal with test cases that may throw or leak exceptions: int cpp_main( int argc, char* argv[] ) { test(); return ::boost::report_errors(); } int main( int argc, char* argv[] ) { try { return cpp_main( argc, argv ); } catch( std::exception const & x ) { BOOST_ERROR( x.what() ); return boost::report_errors(); } } Is there any reason to prefer that one over this one? int main( int argc, char* argv[] ) { try { test(); } catch( std::exception const & x ) { BOOST_ERROR( x.what() ); } return boost::report_errors(); } Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

Strange failure in regression matrix
by Alexander Grund 24 Mar '20

24 Mar '20

Hi, I got a failure of Boost.Nowide develop (and master) for msvc-14.0 in the regression matrix although that configuration is tested as far as I can tell. Furthermore there isn't any indication WHAT failed, see https://www.boost.org/development/tests/develop/developer/output/teeks99-09… Am I missing anything or is this a quirk of the regression tester? Thanks, Alex

Bug in Boost.Asio strand(strand<OtherExecutor>&& other)
by Niklas Gürtler 24 Mar '20

24 Mar '20

Hello, there is a bug in the Boost.Asio strand::strand(strand<OtherExecutor>&& other) move constructor as it tries to do an invalid cast on the wrong object. A friend declaration is also required to access the private members of the other strand. I submitted a PR https://github.com/boostorg/asio/pull/333 to address this issue. Regards, Niklas

Hi, can Boost.Optional be merged to master? There is even a CI failure on develop with a PR fixing this. So would be great if those could be merged shortly. Thanks

[config] Merging 'develop' to 'master' before the 1.73 release
by Edward Diener 23 Mar '20

23 Mar '20

Are the changes in config's 'develop' branch going to be merged to the 'master' branch before the 1.73 release ? The reason I ask is that a config 'develop' PR which I authored is a dependancy of the tti library, ans I can not merge the 'develop' changes of tti into 'master' unless those config changes also are merged to 'master'.

Re: [boost] Looking for Boost.uBlas data frames project GSoC mentors
by Tom Kwok 23 Mar '20

Hi CB, Thank you for your suggestions. I will continue with my proposal and start solving the competency test. David as of now still has not replied though. So I might need to request for mentorship for Boost uBlas data frame GSoC project here. Is anyone interested in offering mentorship and reviewing my proposal and questions?
