Nullable types
by Bjorn Reese 15 Jul '13

15 Jul '13

It seems like different Boost libraries use different nullable types. * Optional uses boost::none * Tribool uses boost::logic::indeterminate_keyword_t * Tuple uses boost::tuples::null_type * Variant uses boost::blank And there are possibly more. What are your opinions about unifying these?

Extremely large Visual Studio libboost_log_setup* binaries
by Tom Kent 14 Jul '13

14 Jul '13

In the 1.54.0 release, I noticed that the size of the binaries built with visual studio was more than twice that of the previous releases. For example the msvc-8.0-64 build went from 2GB to 5GB. Upon further investigation, almost all of that increase was in the libboost_log_setup* binaries, which were each in the 100s of MBs. Does anyone know if there is a reason for this? Is it a configuration error? Tom Kent

Boost.Operators and make_shared
by Pieter 13 Jul '13

13 Jul '13

LS, I have noticed that using Boost.Operators has a side-effect which I can't explain. I am using std::make_shared as a default, however, some of the boost libraries I use pull in boost::make_shared as well. When using some class T2 derived from one of the boost.operators classes, this causes MSVC2010 to not compile when invoking make_shared<T2> as the compiler can no longer resolve between the two overloaded versions of make_shared for some reason. I am hoping that someone out can explain what is happening here. A minimal example is included here: #include <memory> #include <boost\operators.hpp> #include <boost\make_shared.hpp> struct T1 {}; struct T2 : boost::equality_comparable<T2> {}; int main( int argc, const char* argv[] ) { T1 Object1; T2 Object2; using std::make_shared; std::shared_ptr<T1> Ptr1 = make_shared<T1>(Object1); // OK std::shared_ptr<T2> Ptr2 = make_shared<T2>(Object2); // error C2668: 'boost::make_shared' : ambiguous call to overloaded function return 1; } Thanks in advance!

[regression] patch for running tests in parallel and out-of-sync files
by Robert Kawulak 13 Jul '13

13 Jul '13

When I was running tests in parallel (using b2 -j option) I was getting random warnings in the results table because "msvc.manifest" lines were interleaved with compile/link actions. I've fixed this with the attached patch - is it OK to apply it to trunk/release? BTW, I've noticed that the following files in tools/regression/src haven't been updated in release branch even though they've been changed in trunk a long time ago: compiler_status.cpp (trunk date 2012-01-21, release date 2011-10-06) library_status.cpp (trunk date 2013-03-25, release date 2013-03-09) Is it OK to update these in release branch? Best regards, Robert

[config] Feature request: BOOST_OVERRIDE
by Borislav Stanimirov 12 Jul '13

12 Jul '13

Hi, I think it will be a nice feature to add BOOST_OVERRIDE to Boost.Config in a manner similar to BOOST_CONSTEXPR. It's a nice keyword and it would be nice if people could make use of it when it's available. -- Borislav
