Hello! I am new to boost community and i want to know about current status of "CMake modularization" project. I try to build boost according this page: https://svn.boost.org/trac/boost/wiki/CMakeModularizationStatus, and i`ve got some issues during configuring and building under win32, and i have some ideas how to fix them, but i didn`t see any activity since May 2012. I see Is this project alive?

[utf8_codecvt_facet]
by Robert Ramey 06 Jan '13

06 Jan '13

change Revision: 81616 Author: marshall Date: 11:12:42 AM, Wednesday, November 28, 2012 Message: Fixed incorrect 'const' param for utf8_codecvt_facet::do_length ---- Modified : /trunk/boost/detail/utf8_codecvt_facet.hpp This change causes the a failure in the serialization library test suite with "test_utf8_codecvt" on all platforms which use the gcc standard library. I'm not sure what motivated the change or what it addressed but I'm pretty sure it's causing this (and a couple other) test failures. Note that all the failures are related to usage of wchar_t - perhaps that helps. Note that the test is part of the serialization library test suite - but it has nothing to do with serialization per se and doesn't use any of the serialization library. It just happens to be there because there was no more convenient place to put it. Marshall - could you please look into this? Robert Ramey

[Release][Spirit] Asking for approval to merge bugfix
by Hartmut Kaiser 06 Jan '13

06 Jan '13

Hey, I somehow missed to merge one commit from trunk to the release branch (see attached). May I commit this to fix a compilation problem in Spirit? The patch is very low risk as it just renames a parameter. Regards Hartmut --------------- http://boost-spirit.com http://stellar.cct.lsu.edu

[Locale] Security bug announcement - UTF-8 validation
by Artyom Beilis 06 Jan '13

06 Jan '13

Hello, Boost.Locale library in Boost 1.48 to 1.52 including has a security flow. boost::locale::utf::utf_traits accepted some invalid UTF-8 sequences. Applications that used these functions for UTF-8 input validation could expose themself to security threats as invalid UTF-8 sequece would be considered as valid. This bug is fixed in upcoming Boost 1.53. For more details see: https://svn.boost.org/trac/boost/ticket/7743 Users who can't upgrade to the latest versions may apply the following patch to fix the problem. http://cppcms.com/files/locale/boost_locale_utf.patch Regards, Artyom Beilis -------------- CppCMS - C++ Web Framework: http://cppcms.com/ CppDB - C++ SQL Connectivity: http://cppcms.com/sql/cppdb/

[config] MSCV 10 defines BOOST_NO_CXX11_HDR_TUPLE with a C++03 implementation
by Vicente J. Botet Escriba 05 Jan '13

05 Jan '13

Hi, The current implementation of boost::make_unique_locks needs a std::tuple with C++11 move semantics.* *MSCV 10 provides <tuple> and rvalue references so that BOOST_NO_CXX11_HDR_TUPLE and BOOST_NO_CXX11_RVALUE_REFERENCES are not defined. However I suspect that the implementation provided by <tuple> with this version is the one corresponding to TR1 and doesn't provide move semantics as the message in http://tinyurl.com/atjdoh3 could let think. Could someone confirm my suspicion?* *Is there a way to request MSVC 10 to not import TR1 files? Should BOOST_NO_CXX11_HDR_TUPLE be defined for MSVC 10 as it doesn't implements the c++11 semantics while BOOST_NO_HDR_TUPLE could be undefined? * *Best, Vicente ** Test output: id - thread - make_unique_locks__mutex_p / msvc-10.0 Rev 82343 / Thu, 3 Jan 2013 23:15:13 +0000 *Report Time: *Sat, 5 Jan 2013 12:53:31 +0000 Compile [2013-01-04 08:34:35 UTC]: fail call "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" x86 >nul cl /Zm800 -nologo @"c:\boost\regression\trunk\results\boost\bin.v2\libs\thread\test\make_unique_locks__mutex_p.test\msvc-10.0\debug\threading-multi\sync\mutual_exclusion\locks\unique_lock\cons\make_unique_locks_mutex_pass.obj.rsp" make_unique_locks_mutex_pass.cpp c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\tuple(79) : error C2558: class 'boost::unique_lock<Mutex>' : no copy constructor available or copy constructor is declared 'explicit' with [ Mutex=boost::mutex ] c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\tuple(77) : while compiling class template member function 'std::tr1::_Cons_node<_Car,_Cdr>::_Cons_node(const std::tr1::_Cons_node<_Car,_Cdr> &)' with [ _Car=boost::unique_lock<boost::mutex>, _Cdr=std::tr1::_Cons_node<boost::unique_lock<boost::mutex>,std::tr1::_Cons_node<boost::unique_lock<boost::mutex>,std::tr1::_Tuple_type<std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil>::_Type>> ] c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\tuple(479) : see reference to class template instantiation 'std::tr1::_Cons_node<_Car,_Cdr>' being compiled with [ _Car=boost::unique_lock<boost::mutex>, _Cdr=std::tr1::_Cons_node<boost::unique_lock<boost::mutex>,std::tr1::_Cons_node<boost::unique_lock<boost::mutex>,std::tr1::_Tuple_type<std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil,std::tr1::_Nil>::_Type>> ] ..\libs\thread\test\sync\mutual_exclusion\locks\unique_lock\cons\make_unique_locks_mutex_pass.cpp(41) : see reference to class template instantiation 'std::tr1::tuple<_Arg0,_Arg1,_Arg2,_Arg3,_Arg4,_Arg5,_Arg6,_Arg7,_Arg8,_Arg9>' being compiled with [ _Arg0=boost::unique_lock<boost::mutex>, _Arg1=boost::unique_lock<boost::mutex>, _Arg2=boost::unique_lock<boost::mutex>, _Arg3=std::tr1::_Nil, _Arg4=std::tr1::_Nil, _Arg5=std::tr1::_Nil, _Arg6=std::tr1::_Nil, _Arg7=std::tr1::_Nil, _Arg8=std::tr1::_Nil, _Arg9=std::tr1::_Nil * *

[Range] Proposal: a sub-maintainer of Boost.Range
by Michel Morin 05 Jan '13

05 Jan '13

Dear Neil, Dear Nate, First I'd like to say thank you for your library, Neil. It is a very useful library and it's great fun to writing codes with range adaptors. Boost.Range is one of the most important Boost libraries that are not yet added to the Standard. I know that Neil has made an effort to make time for developing the library, but recently making time for development seems difficult. And there are several open tickets of trivial bugs (e.g. #5603, #6110). Considering this situation, I'd like to make a proposal about Boost.Range: ** Adding a sub-maintainer to Boost.Range ** This reduces author's maintenance burden and also helps more stable development of the library. I recommend Nathan Ridge as a sub-maintainer of Boost.Range. His knowledge, experiences and contribution to Boost are great. If both of Neil and Nate accept the proposal, and if Nate needs some support for the start-up, I'll try my best to support him. I also believe that Jeff will also support him ;) Neil, what do you think about this proposal? I would appreciate and respect any of your reply. Yours sincerely, Michel

[Release managers] Permission to rollback Boost.Thread breaking changes
by Vicente J. Botet Escriba 04 Jan '13

04 Jan '13

Hi, I would like to apply the following patch to trunk and release branch to avoid the Boost.Thread breaking changes. * [@http://svn.boost.org/trac/boost/ticket/6229 #6229] Rename the unique_future to future following the c++11. * [@http://svn.boost.org/trac/boost/ticket/6266 #6266] Breaking change: thread destructor should call terminate if joinable. * [@http://svn.boost.org/trac/boost/ticket/6269 #6269] Breaking change: thread move assignment should call terminate if joinable. This will let us the time to discuss the best way to manage with this breaking changes. Is someone against this late change?
