Languishing review requests
by Tom Brinkman 06 Jun '07

Thanks John for starting this thread. Our preference has always been to assign the "Review Manager" role to those that have already submitted a library, or at-least an active contributer to boost in some capacity. If no one with this background volunteers, and the proposed library has had sufficient time on the list, we would make the "Review Manager" role available to others. Typically, we would do a search on the mailing list to get a feel for how actively the volunteer has participated in some previous discussions. Often, we will read their comments and make an assessment if they would be a good match for a given library. We have tried to set the "bar" pretty high. It should also be stated that the library author has the responsibility to generate interest in his library. Just having the library added to the "Review Queue" is not enough. He must regularly post comments to this list about issues that are relevant to his library and of interest to boost developers. He should attempt to create a small community of people that have an interest in having the library added. He must be an advocate for his library and tell "us" why it would be a good addition. Successfully submitting a library to boost can be a career changing accomplishment for some. If a library has been on the queue for over six months, and no one has steped up to volunteer to be the "review-manager", there could be a problem with the library and it may not ready for review. Every situation is different. We have no difficulty finding "qualified" review managers for the larger high-profile libraries. However, its the smaller, obscure libraries, that dont have an obvious use-case that have troubles. A little bit of "salesmanship" by the authors of the smaller libraries is often all that is needed to get other developers to take a look at it. Also, many of us like to read discussion threads about the proposed libraries well in advance of the actual review. As far as I can tell, very little of this has been done for the libraries that are currently languashing in the "review queue". In the case of John Phillips, even though he hasn't sumbitted a library; (if I recall correctly), he is a Professor of Mathmatics and has contributed regularly to many discussion on various topics on the boost mailing list. His reviews have always been among the most thoughtful and relevant. We could only hope that all "reviews" are handeled as well his. We are fortunate that he has also voluntered to be the "Review Manager" for the upcoming "review" of Eric Neibler's "Time-series" library. We have had many discussions behind the scenes about how to improve the review process. Hopefully, this thread will start another such discussion.

Boost Inspection Report Run Date: 16:08:16 UTC, Wednesday 06 June 2007 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11453 files scanned 909 directories scanned (including root) 193 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 3 invalid urls 101 broken links 21 unlinked files 22 file/directory names issues 2 files with tabs 9 violations of the Boost min/max guidelines 35 usages of unnamed namespaces in headers (including .ipp files) Summary:

[interprocess] Interprocess build fails on 64-bit MSVC 8
by Aaron W. LaFramboise 06 Jun '07

06 Jun '07

On a 64-bit build on MSVC 8 (CL 14.00.50727.762 for x64) with Boost CVS 2007-06-03, building a program that uses Boost.Interprocess fails. Please see the attachment at the end of the message for the compiler output. The problem is in rbtree_best_fit::SizeHolder: > unsigned m_prev_size : sizeof(std::size_t)*CHAR_BIT - 1; 'unsigned' which is 32-bit is not large enough to hold a 64-bit size_t. If I change 'unsigned' to 'std::size_t' compile is successful without any other errors. When linking, I get: aaron.obj : error LNK2019: unresolved external symbol __imp_InterlockedCompareExchange referenced in function "long __cdecl boost::interprocess::winapi::interlocked_compare_exchange(long volatile *,long,long)" (?interlocked_compare_exchange@winapi@interprocess@boost@@YAJPECJJJ@Z) I was able to fix this by using BOOST_INTERLOCKED_COMPARE_EXCHANGE instead of InterlockedCompareExchange in winapi::interlocked_compare_exchange() in w32_api.h. I had to make a similar translation for InterlockedExchange. With these changes, it appears to compile and link. I can't guarantee yet that it actually works, though. 1>include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(83) : error C2034: 'boost::interprocess::rbtree_best_fit<MutexFamily,VoidPointer>::SizeHolder::m_prev_size' : type of bit field too small for number of bits 1> include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(80) : see reference to class template instantiation 'boost::interprocess::rbtree_best_fit<MutexFamily,VoidPointer>::SizeHolder' being compiled 1> include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(282) : see reference to class template instantiation 'boost::interprocess::rbtree_best_fit<MutexFamily,VoidPointer>' being compiled 1>include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(85) : error C2034: 'boost::interprocess::rbtree_best_fit<MutexFamily,VoidPointer>::SizeHolder::m_size' : type of bit field too small for number of bits 1>include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(83) : error C2034: 'boost::interprocess::rbtree_best_fit<MutexFamily>::SizeHolder::m_prev_size' : type of bit field too small for number of bits 1> with 1> [ 1> MutexFamily=boost::interprocess::mutex_family 1> ] 1> include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(91) : see reference to class template instantiation 'boost::interprocess::rbtree_best_fit<MutexFamily>::SizeHolder' being compiled 1> with 1> [ 1> MutexFamily=boost::interprocess::mutex_family 1> ] 1> include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(269) : see reference to class template instantiation 'boost::interprocess::rbtree_best_fit<MutexFamily>::block_ctrl' being compiled 1> with 1> [ 1> MutexFamily=boost::interprocess::mutex_family 1> ] 1> include\boost/interprocess/detail/managed_memory_impl.hpp(87) : see reference to class template instantiation 'boost::interprocess::rbtree_best_fit<MutexFamily>' being compiled 1> with 1> [ 1> MutexFamily=boost::interprocess::mutex_family 1> ] 1> include\boost/interprocess/managed_windows_shared_memory.hpp(54) : see reference to class template instantiation 'boost::interprocess::detail::basic_managed_memory_impl<CharType,MemoryAlgorithm,IndexType>' being compiled 1> with 1> [ 1> CharType=char, 1> MemoryAlgorithm=boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>, 1> IndexType=boost::interprocess::iset_index 1> ] 1> aaron.hpp(85) : see reference to class template instantiation 'boost::interprocess::basic_managed_windows_shared_memory<CharType,AllocationAlgorithm,IndexType>' being compiled 1> with 1> [ 1> CharType=char, 1> AllocationAlgorithm=boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family>, 1> IndexType=boost::interprocess::iset_index 1> ] 1>include\boost/interprocess/mem_algo/rbtree_best_fit.hpp(85) : error C2034: 'boost::interprocess::rbtree_best_fit<MutexFamily>::SizeHolder::m_size' : type of bit field too small for number of bits 1> with 1> [ 1> MutexFamily=boost::interprocess::mutex_family 1> ]

Computing Random Points on Sphere
by more effective thinking in the exceptional C++ programming language 06 Jun '07

06 Jun '07

Dear, I'm a newcomer on the boost list. I subscribed to share the results of my experiments on picking random points on sphere. This procedure is often a bottleneck for very fast Monte-Carlo simulations of physical process where you must pick vectors in random directions. I compiled a document that explain the experiments and the results. The conclusion contains some propositions to modify boost::random_on_sphere and I would like to know if a new implementation following the presented ideas would be welcome. Colas Schretter

[serialization] 1.34.0 bug
by Sergey Skorniakov 06 Jun '07

06 Jun '07

basic_binary_iprimitive.hpp, basic_binary_iprimitive<Archive, Elem, Tr>::load_binary: std::streamsize s = count / sizeof(Elem); std::streamsize scount = m_sb.sgetn( static_cast<Elem *>(address), s ); if(count != static_cast<std::size_t>(s)) boost::throw_exception( archive_exception(archive_exception::stream_error) ); If sizeof(Elem) != 1, exception will be thrown. Looks like wide binary iarchives was never been tested.

SVN repo structure... [was: Subversion structure in KDE]
by Rene Rivera 05 Jun '07

05 Jun '07

Ping... Any comments on this? It would be nice if people voice some comments on this subject now. Instead of later when we would have to move a bunch of directories around. -------- Original Message -------- Subject: Re: [boost] Subversion structure in KDE Date: Sun, 27 May 2007 17:54:20 -0500 From: Rene Rivera <grafikrobot(a)gmail.com> Henrik Sundberg wrote: > KDE is also a large project with separate subprojects.

The > Boost directory would contain libraries that are to be part of the > next official Boost release, and the Sandbox other libraries. If I'm understanding you, and the KDE docs, correctly, what you want is something like(**): [boost-svn] boost stable (full boost tree here) devel (full boost tree here) branches my_branch (full boost tree here) cmake_a (full boost tree here) cmake_b (full boost tree here) tags boost_1_33_1 (full boost tree here) boost_1_34_0 (full boost tree here) sandbox devel xml (partial boost tree here) explore (partial boost tree here) branches xml_b0 (partial boost tree here) explore_b0 (partial boost tree here) tags xml_for_review (partial boost tree here) explore_for_review (partial boost tree here) That seems like a reasonable arrangement to me. It has the beauty of being easy to explain, and it's not too far off from what we have now. The one drawback I can see is that one common case, of updating boost/stable and boost/devel can't be done in one go. But I think that's a reasonable aspect to give up (not that we had it in the first place) since hopefully working with both at the same time will be an infrequent task. (**) I'm ignoring the website tree because it's not the same kind of beast. Since it only has to deal with two versions, and doesn't need tags. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

[preprocessor] nested sequences?
by Eric Niebler 05 Jun '07

05 Jun '07

I must be doing something stupid. How can I process a sequence of sequences? I expected to be able to use nested invocations of SEQ_FOR_EACH, but I'm not getting the results I expect. Here's my code: #include <boost/preprocessor.hpp> #define INNER(R, DATA, ELEM)\ **ELEM**, #define OUTER(R, DATA, ELEM)\ << BOOST_PP_SEQ_FOR_EACH_R(R, INNER, ~, ELEM) >>, BOOST_PP_SEQ_FOR_EACH(OUTER, ~, ((1)(2)) ((3)(4)) ) I expected something like: << **1**, **2**, >>, << **3**, **4**, >>, But instead I'm getting: << BOOST_PP_SEQ_FOR_EACH_M(3, (INNER, ~, (1)(2) (nil))) BOOST_PP_SEQ_FOR_EACH_M(4, (INNER, ~, (2) (nil))) >>, << BOOST_PP_SEQ_FOR_EACH_M(4, (INNER, ~, (3)(4) (nil))) BOOST_PP_SEQ_FOR_EACH_M(5, (INNER, ~, (4) (nil))) >>, I've tried both msvc-8.0 and gcc-3.4. Can anybody see my mistake? -- Eric Niebler Boost Consulting www.boost-consulting.com

[1.34.1] Bug #990 fixed
by Hartmut Kaiser 05 Jun '07

05 Jun '07

Hi all, I just fixed #990: 'spirit's file_iterator truncates file size value on Windows x64'. This involved changing some long's to std::ptrdiff_t. All related tests pass on the platforms available to me (Win32/64, VC8SP1). Currently, the fix is applied to CVS::HEAD only. Is it ok to apply it to the 1.34 branch as well? Regards Hartmut

[typeof] How to know whether a expression is void?
by Atry 05 Jun '07

05 Jun '07

Hi everybody, I have an template function, and I want to know if it return void, but it does not work: template<typename T> struct is_foo_void : boost::is_void<BOOST_TYPEOF(T::foo(123))>{}; struct foo_struct { template<typename T> static void foo(T){} }; BOOST_STATIC_ASSERT(is_foo_return_void<foo_struct>::value); //////////////////////////////////////////////////////////// Yes, I know funtion_traits would be help if I have a non-template function, but in this case I can't, what should I do?

boost.devel archive at ActiveState disconnected
by Malte Clasen 05 Jun '07

05 Jun '07

Hi, the Boost website says that ActiveState has a searchable mailing list archive of boost.devel (http://www.boost.org/more/mailing_lists.htm#archive) However, this archive is apparently disconnected since 2005 due to "excessive bounces" (http://aspn.activestate.com/ASPN/Mail/Message/boost/2844681) It would be helpful to either reactivate this account or remove the link from the boost site. Best regards, Malte
