Getting involved in Boost
by Anteru 18 Jun '09

18 Jun '09

Hi, I'm a Boost user since quite some time now (1.33 or so), however, I did not contribute a library to Boost, and I was also not too active on the news groups (a few posts so far, at most.) When I look at the review queue, I can see lots and lots of interesting libraries waiting. So my question is: How can I, primary a Boost user, contribute to the community to help with getting new libraries into Boost? Primary, I'd be interested in PIMPL and the ThreadPool, possibly in AutoBuffer and Sorting. Is there some recommended way of reviewing a library "out-of-order" with no review manager, such that the review is easily identifiable and can be found when it comes to the real review? For me, it seems to be no problem to gather reviews of a library up-front. This could make it easier for a review manager to do his work, as he could simply start a formal review only after a certain number of reviews has been done. Side note: I couldn't find a recent review status on the website -- under Development, Submissions, the latest report is from 2008, while the one latest one I could find is from June 2009. However, it does not say what the current status of the UUID is -- did I miss some obvious page with the status of all libraries? Cheers, Anteru

some mpl programming task -- don't get this compiled
by Peter Foelsche 18 Jun '09

18 Jun '09

I'm still unclear about some fundamentals of the mpl library. Could somebody have a look at this source code? I'm playing around with this since quite a while. I'm trying to convert some information into an array of strings. I'm using boost::mpl::map instead of vector as I want to overwrite points in a two dimensional matrix. So in fact this is a map indexed by a long containing another map indexed by a long containing char. Two dimensional quadratic matrix of char. Thanks Peter

[date_time] [#1861] Change for the default duration format
by Andrey Semashev 17 Jun '09

17 Jun '09

Hi, There's a Boost.DateTime ticket: https://svn.boost.org/trac/boost/ticket/1861 The initial problem was that the default handling of the %H format specifier (passing it to strftime) played badly with time durations that could be longer than 24 hours. The resolution was to provide additional %O format specifier that does not have 24 hour restriction. However the original poster proposes to change the default format of time durations from %H:%M:%S%F to %O:%M:%S%F so that formatted durations are always allowed to be longer than 24 hours. I mostly agree with this change, however it is clearly a breaking change that can affect error checking in some cases. What do the community and the maintainer (Jeff?) in particular think about this?

Proposal: MapReduce library (single machine)
by Craig Henderson 17 Jun '09

17 Jun '09

MapReduce is a programming model from Google that is designed for scalable data processing. Google's implementation is for scalability over many thousands of commodity machines, but there is value in using the idiom on multi-core processors to partition processing to efficiently use the CPU available, and avoid the complexities of multi-threaded development. I have a implemented a MapReduce runtime library in C++ using Boost and would like to see if there is interest from you all to submit the library to Boost. I have preliminary documentation on my website at http://www.craighenderson.co.uk/mapreduce/ Regards -- Craig Craig Henderson <http://craighenderson.co.uk/> http://www.craighenderson.co.uk http://www.siteupdatenotification.com

Compilation error in boost::bind
by Zachary Turner 17 Jun '09

17 Jun '09

The documentation for __stdcall in MSVC says the following: On Itanium Processor Family (IPF) and x64 processors, __stdcall is accepted and ignored by the compiler. Because of this, the following fragment from <boost/bind/bind.hpp> fails when causes build errors for either of these platforms: #define BOOST_BIND_CC #define BOOST_BIND_ST #include <boost/bind/bind_cc.hpp> #undef BOOST_BIND_CC #undef BOOST_BIND_ST #ifdef BOOST_BIND_ENABLE_STDCALL #define BOOST_BIND_CC __stdcall #define BOOST_BIND_ST #include <boost/bind/bind_cc.hpp> #undef BOOST_BIND_CC #undef BOOST_BIND_ST #endif Since it ignores the __stdcall the second time around, all the templates are re-declared with cdecl causing duplicate symbol definition errors. This is confirmed on MSVC 9.0 but I assume it exists on all versions of MSVC. What is the best way to fix this? I don't know much about how to use the BOOST_WORKAROUND macros, but I have patched this in my own version of bind.hpp by changing the block inside the ifdef to the following: #if defined(BOOST_BIND_ENABLE_STDCALL) && !(defined(BOOST_MSVC) && defined(_WIN64)) #define BOOST_BIND_CC __stdcall #define BOOST_BIND_ST #include <boost/bind/bind_cc.hpp> #undef BOOST_BIND_CC #undef BOOST_BIND_ST #endif This doesn't handle the itanium case obviously but off the top of my head I'm not sure what MSVC #defines for itanium. What would be the most robust way to fix this?

[mpl] is there a or_seq like logical metafunction?
by vicente.botet 17 Jun '09

17 Jun '09

Hello, I needs calculate the mlp::or_ of a sequence of nullary logical metafunction. This seams quite simple. I have do the following: <code> template <typename Seq> struct or_seq; template <typename Seq, long N> struct or_seq_aux : mpl::or_< typename mpl::front<Seq>::type, or_seq<typename mpl::pop_front<Seq>::type> > {}; template <typename Seq> struct or_seq_aux<Seq, 1> : mpl::front<Seq>::type {}; template <typename Seq> struct or_seq : or_seq_aux<Seq, mpl::size<Seq>::value> {}; </code> Is there a boost or_seq like logical metafunction? Is there a better way to do it? I would be extremely interested in any suggestions. Best regards --------------------------- Vicente Juan Botet Escriba

Interest in a Bloom Filter?
by Dean Michael Berris 17 Jun '09

17 Jun '09

Hi Everyone, During the weekend, I got acquainted with and excited about Bloom Filters and the utility of such a data structure. I then proceeded to look at generic implementations of a bloom filter and I thought about implementing one myself instead as a simple exercise. Attached is what I came up with which I'm submitting as a library for review (and uploading to the vault). Also attached is a sample program which uses the bloom_filter. I've yet to write some documentation about it, which would be in the list of things to do in case there's enough interest for the library to be included in Boost. Thanks in advance and I hope this helps! -- Dean Michael Berris | Software Engineer, Friendster, Inc. blog.cplusplus-soup.com | twitter.com/mikhailberis | linkedin.com/in/mikhailberis | profiles.friendster.com/mikhailberis | deanberris.com

Boost on solaris compiled and linked with libCstd
by CREMARENCO Cosmin 16 Jun '09

16 Jun '09

Hi We have a solaris distribution of our software and we would like to use the boost libraries. In my understanding you recommend compiling and linking with stlport. However we depend on third party libraries that were built with libCstd, which is the old standard non-conformant library from sun. Sun docs clearly state that one should use either stlport or libCstd in the same program but not both. Also, we use sun studio 11. Now, we tried building boost with libCstd. A number of libraries built without problems: date, iostreams, prg, signals, system. In our application we use mostly header-only libraries and a small number of libraries that need to be linked with the program. We could get program-options (which we use extensively) to build by patching it (a tentative patch for 1.39 is attached). Of course one also needs to change tools/build/v2/tools/sun.jam in order to disable compiling and linking with stlport. My question is: if we send patches that allow boost to be compiled and linked with libCstd is there a chance that you will accept them in your main codeline? Best regards, Cosmin

[test] Untraceable Boost.Test framework internal error: unknown reason
by Peter Soetens 16 Jun '09

16 Jun '09

Hi, I'm using Boost 1.37.0 (Ubuntu Jaunty). When I run my testcases, they seem to complete well, but just before the end of the program exit, I get this error from Boost UTF: Boost.Test framework internal error: unknown reason FATAL: exception not rethrown Aborted I spent an hour trying to figure out 1) how to find out where the exception was thrown and 2) if the exception catching in boost could be disabled such that a simple gdb backtrace could point me to it. I have the suspicion that one of the signal handlers that boost UTF installs gets triggered, but I also did not find any way to disable the boost signal handlers. I'm really out of options... Any help/hints (would upgrading boost help?) really appreciated. Peter
