Hello everyone, I already asked that question, but how the library has changed a lot since the last inquiry. "Is there any interest in a library which provides Application Environment using Aspect Based Design?"

[range] fat iterators?
by Eric Niebler 13 Nov '13

13 Nov '13

I wrote an article describing the "fat" std::istream_iterator and how it can be slimmed down by giving it an owning istream_range[1]. I see there already is an istream_range in Boost.Range, but it suffers from the fat-iterator problem I describe there. Is there a compelling reason why the implementation of boost::istream_range shouldn't be changed to be more like the one I describe? Also, as a commented pointed out, the same problem exists for the filtered range and the transformed range, too. The trick, of course, will be keeping intermediate temporary ranges alive long enough to avoid lifetime issues when we chain adaptors and assign the result to a local variable. I think a range library that's sensitive to the value category of range objects and makes copies of rvalue ranges would solve this problem. Thoughts? Is it time for Boost.Range 3.0?

Re: [boost] [Functional/Factory] Value factory not accepts rvalues?
by THOMAS JORDAN 13 Nov '13

Lin, Yi-Li wrote: > I found that boost::value_factory did not accept rvalues > in some case. > In my case, temporary value is produced and passed to > value factory directly. The documentation for Boost Functional/Factory states: 'For technical reasons the arguments to the function objects have to be LValues. A factory that also accepts RValues can be composed using the boost::forward_adapter or boost::bind.' Your suggestion of using const lvalue (passing in non-const reference wrappers where needed) seems to be the workaround for the C++03 perfect forwarding problem that was employed by Boost smart_ptr::make_shared, not sure why Functional/Factory took a different approach?

Patch in Ticket #9212 (Broken links to C++ standard papers)
by Michel Morin 13 Nov '13

13 Nov '13

Jonathan Wakely pointed out "Broken links to C++ standard papers" issue and attached a patch in #9212. ( https://svn.boost.org/trac/boost/ticket/9212 ) Though this patch is a large Boost-wide patch, it's very simple so I think someone can commit it to every library at once. Regards, Michel

[1.55][log] Last minute bug fix
by Andrey Semashev 12 Nov '13

12 Nov '13

Hi, Is it too late for a fix in Boost.Log in 1.55? Here's the commit: https://svn.boost.org/trac/boost/changeset/86600 This fixes garbage output when using dump() manipulator on CPUs with AVX2 support. The bug didn't appear on any of our testers because apparently none of them have Haswell CPUs. I tested this change locally on Linux, gcc 4.8, but it should be valid on all platforms. If it's too late already then maybe a note with the patch in the release notes would be possible?
