Re: [boost] [units] Pull request and RFC: information unit definitions for Boost.Units

Hi all, I considered proposing myself as a maintainer of Boost.Units for some time, but considered too inexperienced to do it on my own. Therefore I am happy that Jürgen proposed himself and I would like to help him by being a co-maintainer if it is possible and needed. As for me, I have been using the library for at least 3 years now and would like to contribute to it. For the moment, I mainly proposed small bug fixes to Boost libraries.

[config][type_traits] Support for final keyword in Boost?
by John Maddock 16 Aug '14

16 Aug '14

I have a couple of pull requests to add support for the final keyword in Boost.Config and an is_final trait to type traits, so my questions are: 1) Are these generally useful? 2) Do we need BOOST_NO_CXX11_FINAL_CLASS and BOOST_NO_CXX11_FINAL_OVERRIDE or will a single BOOST_NO_CXX11_FINAL do? 3) The trait appears to be unimplementable via SFINAE (anyone care to prove me wrong?) which means it's only usable on GCC and lookalikes which have an __is_final intrinsic. Should we still add this to Boost or is the answer "use GCC's native features" given that a Boost version effectively adds nothing? Thanks! John.

[docbook] Add detail namespace to Reference section
by Benedek Thaler 16 Aug '14

16 Aug '14

Hi, I have the following example code fragment: namespace boost { namespace detail { /** documentation */ class implementation {}; } // namespace detail using detail::implementation; } // namespace boost I'd like to have the class `implementation` show up in the Reference section generated by doxygen+docbook-xsl+boost build+docbook+... . Issue is, every namespace which name contains the string "detail" is excluded somehow. The direct output of doxygen has it, but not the docbook version. I couldn't find any EXCLUDE_SYMBOLS setting (it's not set in the doxyfile)or anything relevant amongst the docbook-xsl params or in the boost build scripts. Google search term "doxygen ignores detail namespace" and the like did not help. Adding documentation to the using statement and/or TYPEDEF_HIDES_STRUCT did not help. Thanks, Benedek

Should intrusive_ptr copy constructors be declared noexcept?
by James Yonan 16 Aug '14

16 Aug '14

Currently, intrusive_ptr's copy constructors are not declared noexcept. This disables the std::function small object optimization when intrusive_ptr objects are passed by value in a lambda closure. The attached patch tries to fix this by making the copy constructors conditionally noexcept, based on the noexcept status of the user-provided intrusive_ptr_add_ref function. James

[Boost][filesystem] imbue in global constructor crashes
by Peter Bindels 15 Aug '14

15 Aug '14

Hi all, When trying to use a global constructor to set the locale to utf8 for an entire project, the system failed to start due to global constructor ordering making the override happen before the std::locale object itself was initialized. Looking into the boost::filesystem code for imbue it seemed that there were a few different implementations, one of which could work. I've tried to keep the same side conditions and made this same lazy-initialization approach for all platforms, which should keep working in all the same conditions and also work for a global constructor overriding the locale. I've attached the patch. I hope that this change can be integrated into boost::filesystem or that we can have a constructive discussion on what solution we should be making. Best regards, Peter Bindels

[variant] static_visitor constructor error with boost 1.56.0 and g++ 4.5.1
by Richard Hadsell 15 Aug '14

15 Aug '14

I am trying to upgrade from Boost 1.55 to 1.56. I get this error with G++ 4.5.1: In file included from ...: .../boost/variant/static_visitor.hpp:52:24: error: 'boost::static_visitor<R>::static_visitor()' declared with non-public access cannot be defaulted in the class body .../boost/variant/static_visitor.hpp:53:25: error: 'boost::static_visitor<R>::~static_visitor()' declared with non-public access cannot be defaulted in the class body The OS is Linux Fedora 14. The compiler is gcc version 4.5.1 20100924 (Red Hat 4.5.1-4). I saw a similar problem in noncopyable.hpp, when upgrading to Boost 1.55. Andrey Semashev fixed it, and it looks like static_visitor requires the same fix. In static_visitor.hpp change line 51 from #ifndef BOOST_NO_DEFAULTED_FUNCTIONS to #if !defined(BOOST_NO_CXX11_DEFAULTED_FUNCTIONS) && !defined(BOOST_NO_CXX11_NON_PUBLIC_DEFAULTED_FUNCTIONS) I think this would be appropriate for any non-public defaulted functions, not just the ones that trip up code I happen to compile.

The PDF build of Boost's documentation for 1.56 is now available from the usual address: https://sourceforge.net/projects/boost/files/boost-docs/1.56.0/ Note that it includes only the subset of Boost libraries whose documentation is quickbook/docbook based. John Maddock.

Boost Library Writers Workshop at CPP Con 2014
by Robert Ramey 14 Aug '14

14 Aug '14

Have you been lurking out there in cyberspace all these years? Slaving away on your fantastic new library for boost? Stuck, discouraged, concerned about getting ripped apart on the mailing list? Well, this is for you !!!! The Boost Library Writers Workshop http://rrsd.com/blincubator.com/open-content/ . Share your library and get it critiqued by you peer group - other unsung authors battling the same daemons. Best of all you can attend this workshop without being registered at the conference - to attend this workshop all you have to do is ... attend!. That's right, it's absolutely free. That's right free. And not free like in free software. Really free like "free beer". (note: there is no free beer). So if you're in the area and you want to get your library off your chest because it's weighing you down, keeping you awake, ruining your love life attend this workshop. Spaces are limited so signup now at the above web page.

[GitHub] Transferring a new library's repo to boostorg?
by Beman Dawes 14 Aug '14

14 Aug '14

https://svn.boost.org/trac/boost/wiki/NewLibFromGit describes "Creating a new library from an existing Git repository". It seems to cover the case where the existing git repo isn't in the exact boost branch organizational structure required. The Boost Endian library is ready to be moved to boostorg on GitHub so it can be tested on develop, checked by release managers, and otherwise readied to be added to 1.57.0. It is already on GitHub and AFAIK has the usual boost branch and directory structure. GitHub has a mechanism to transfer a repo between users or organizations. This would seem the easiest and most direct approach for boost endian. Is there any reason not to give it a try, and if it works as advertized then add it to https://svn.boost.org/trac/boost/wiki/NewLibFromGit as an additional option? --Beman
