Boost Support for Android and iOS
by rohit dhamija 25 Jan '13

25 Jan '13

Hi, Boost libraries are intended to be widely useful, and usable across a broad range of applications, but yet there is no official support available for Android and iOS 1. Is there any specific reason behind the same (like not optimized for embedded devices)? Or any other reason? 2. Are there (at all) any known issues if we use boost libraries for networking and thread synchronization for Smartphone application development ? Will it be a good idea to use BOOST ASIO for the same? I found some articles to compile boost but it would be great if we have some official links. FYI are the links found https://github.com/MysticTreeGames/Boost-for-Android http://www.codexperiments.com/android/2011/05/tips-tricks-building-boost-wi… RDX

[variant] Basic rvalue and C++11 features support
by Antony Polukhin 20 Jan '13

20 Jan '13

Hi, There is a patch in ticket #7620 that adds some rvalue assignment operators and rvalue constructors for Boost.Variant library. I saw no activity from authors of Boost.Variant Eric Friedman and Itay Maman for a long time, so if there will be no objections, I'll commit patch to trunk in the middle of November. Any suggestions and comments are welcomed. -- Best regards, Antony Polukhin

Changes to VS 2012 config
by Marshall Clow 17 Jan '13

17 Jan '13

Just so people know - I'm updating the Visual Studio configuration to more accurately reflect the capabilities of VS 2012. The first step was in http://svn.boost.org/trac/boost/changeset/81613 ; the next step will be to update the compiler features. If you see any problems, please let me know. -- Marshall

[parameter] std proposal
by Lorenzo Caminiti 07 Jan '13

07 Jan '13

Hello all, Is there a C++ standard proposal for named parameter addition? I am looking for an "N-paper" for named parameters similar to N2081 for concepts, or N1962 for contracts. Thank you. -- Sent from my mobile device Lorenzo

[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

[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: Boost.Thread breaking changes in 1.53
by Vicente J. Botet Escriba 04 Jan '13

04 Jan '13

Hi, there has been some threads about the following Boost.Thread breaking change in release 1.53. "Breaking changes when BOOST_THREAD_VERSION==3 (Default value since Boost 1.53): There are some new features which share the same interface but with different behavior. These breaking features are provided by default when BOOST_THREAD_VERSION is 3, but the user can however choose the version 2 behavior by defining the corresponding macro. As for the deprecated features, these broken features will be only available until boost 1.55. * [@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. " I would like to request advise from the release managers and of course the Boost community. Should I rollback the default to BOOST_THREAD_VERSION==3 for 1.53 and let the time to discuss the best way to manage with these breaking changes? Best, Vicente

utf8_codecvt facet - volunteer opportuntiy
by Robert Ramey 03 Jan '13

03 Jan '13

Our implementation for a codecvt facet internal wide char to/from utf8 format requires some maintainence. We have our own implementation since 2001. Since then, the standard libary has come to specify some implementations and some libraries have implemented some or all of this aspect of the standard library. I've come to believe that we should: a) tweak our code to use the standard library implementations if they exist. b) tweak our code to use the names of the standard library implementation b) tweak our build so that our version replaces the the standard library implementation when and only when there is no standard implemenation available. This seemingly simple task is complicated by the following circumstances. a) The relationshp between UCS and Unicode is pretty confusing. b) The iterface for codecvt is confusing. c) a number of standard library implementations have non-conforming codecvt interface. d) a number of standard library implementations don't have any codecvt header at all. This is not a problem for our current implementation because we never import it. Anyone interested in working on this should contact Marshall, Beman or myself (in that precedance). Robert Ramey

[config] Proposed BOOST_NOEXCEPT_NOTHROW macro
by Beman Dawes 03 Jan '13

03 Jan '13

The three current BOOST_NOEXCEPT* macro variants miss the case where C++03 code has a "throw()" throw-specifier. Classes that derive from standard library exceptions need this to avoid breaking code on C++03 compilers. I'm not enamored with the BOOST_NOEXCEPT_NOTHROW name, so feel free to offer suggestions for alternate names. Here is the full set of macros: #ifdef BOOST_NO_NOEXCEPT # define BOOST_NOEXCEPT # define BOOST_NOEXCEPT_NOTHROW throw() <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) # define BOOST_NOEXCEPT_EXPR(Expression) false #else # define BOOST_NOEXCEPT noexcept # define BOOST_NOEXCEPT_NOTHROW noexcept <---- new macro # define BOOST_NOEXCEPT_IF(Predicate) noexcept((Predicate)) # define BOOST_NOEXCEPT_EXPR(Expression) noexcept((Expression)) #endif Unless there are objections, I'll commit the changes Wednesday afternoon Eastern US time. --Beman

Flow-based programming library for Boost?
by Marcus Tomlinson 03 Jan '13

03 Jan '13

Is there any interest out there for a library that allows you to create fast, efficient flow-based programs with an easy-to-use object-oriented interface? (http://en.wikipedia.org/wiki/Flow-based_programming) I've created an open-source library that does this, called "DSPatch" ( http://sourceforge.net/projects/dspatch) and would like to contribute it to the Boost Libraries. Please let me know if this sounds like something you'd like to see in Boost. Thanks!

[string_ref] Feature requests
by Daniel James 01 Jan '13

01 Jan '13

Hi, I've been trying to convert quickbook to use boost::string_ref, and there are a few missing features that might be useful: Construction from a pair of iterators, either std::basic_string::const_iterator, or boost::basic_string_ref::const_iterator. Which of course can be the same type, which is annoying but not too hard to work around. Easy conversion to std::basic_string. There's a C++11 explicit string operator, but that isn't much good for portable code. Something like a 'string' or 'to_string' member would do the trick. Support for comparisons with std::basic_string. The comparison operators are templates so they aren't called with an implicit conversion. Could use a template parameter for the type so that it picks up anything which is (implicitly?) convertible to boost::basic_string_ref, maybe using SFINAE. I didn't need it, but could probably also could do with a 'hash_value' function for boost::hash support. Is potentially error prone if the original string is modified or destroy, but there are some valid use cases. thanks, Daniel

[exception][iostream] link error in boost_1_52_0
by Jeff Flinn 31 Dec '12

31 Dec '12

I'm getting the following link error using boost_1_52_0 with Xcode 3.2.6 gcc 4.2: "std::bad_alloc::what() const", referenced from: vtable for boost::exception_detail::error_info_injector<std::bad_alloc>in libboost_iostreams-mt.a(zlib.o) vtable for boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::bad_alloc> >in libboost_iostreams-mt.a(zlib.o) Boost exception is listed as a header only library, but there is clone_current_exception_non_intrusive.cpp in ..\boost_1_52_0\libs\exception\src. Does boost.exception lib need to be built? thanks, jeff

[Git] Regression testing modular Boost
by Beman Dawes 30 Dec '12

Starting a new thread - this is far to important to bury in the long documentation thread!

None yet. I've been assuming we will just update www.boost.org/development/running_regression_tests.html > What changes to the current tools need to happen to the adjust to > the new setup? As a first cut, branch the current tools and convert any code that currently uses svn commands to use git commands. But before any testing is done, it would be helpful if Boost.Build was updated to handle the generation of boost-root/boost header file links, rather than relying on the workaround cmake script. Do you feel comfortable enough with git to handle the conversion? --Beman

[Git] Modularization of Boost.Any, Boost.Array, and Boost.StaticAssert
by Daniel Pfeifer 29 Dec '12

29 Dec '12

Hi, according to our preliminary modularization, the candidates Boost.Any, Boost.Array, and Boost.StaticAssert each have their own repository, even though each of them consists of a single header file only (disregarding tests, examples and documentation). I propose to put all three of them into the Boost.Utility repository. Comments? --Daniel

[git] Boost.Build location
by Vladimir Prus 29 Dec '12

29 Dec '12

I am wondering what will be the location of Boost.Build after the git switch. It seems to be part of http://github.com/boost-lib/boost right now. Maybe, it would be best to have separate git repository for Boost.Build? In particular, that would allow to fork just Boost.Build, which is important given git's inability to handle partial checkouts. It would also allow giving push access for Boost.Build to other people, without also giving access to superproject. Comments? Thanks, Volodya

[python] Proposal: RAII for Global Interpreter Lock (GIL)
by John Zwinck 29 Dec '12

29 Dec '12

There are many questions and example classes online for dealing with Python's Global Interpreter Lock (GIL) using RAII. I think Boost.Python should provide this functionality, rather than having users who build hybrid C++/Python applications copy-pasting code from various places. I was one of those users recently, and the code I developed to deal with it is now public: https://github.com/jzwinck/pccl/blob/master/InterpreterLockGuard.hpp https://github.com/jzwinck/pccl/blob/master/InterpreterLockGuard.cpp https://github.com/jzwinck/pccl/blob/master/test/InterpreterLockGuard.test.… Comments in the header explain how to use it in the context of Boost.Python, and contain a link to a wiki from which some of the code was originally copied. Why add this to Boost? It's clearly code that a bunch of people need, often people who are already using Boost.Python. It has a permissive license, and I can re-license it if need be. And it depends on Boost (mostly for thread-specific storage--I hope this dependency won't be seen as a liability here, though it could be removed if needed). This particular implementation was used successfully in a few programs in a commercial setting on Fedora and RHEL systems. It has some extra checks that we found helpful compared to some of the versions you'll find posted online. The code also builds and passes its tests with GCC on Mac OS X. I welcome any feedback regarding the suitability for inclusion in Boost of this particular code and/or the concepts it implements. John Zwinck
