The cpp-netlib Release 0.8 is Out Now!
by Dean Michael Berris 19 Nov '10

19 Nov '10

Hi Everyone, advanced apologies for the cross-post. To those interested and watching the cpp-netlib project's progress, this afternoon Philippine time I just packaged and released the latest installment of the cpp-netlib project. Release 0.8 features: * An asynchronous HTTP server template, supporting asynchronous handler invocation and asynchronous writing to the established HTTP connection on the handler side. An example of one use for this is included in the library which implements a simple static web server, benchmarked with Apache AB on a dual core Intel Core 2 CPU with 2GB RAM to be able to serve a 10kb file at 4700 requests per second on 64-bit Linux 2.6.36. You can find out more about the example here: http://goo.gl/5mVuY * More in-depth documentation covering the HTTP Client and Server APIs, now hosted online as well. Read the documentation at http://cpp-netlib.github.com/0.8/ * A simple thread pool implementation that uses Boost.Asio underneath, with a simple API for posting nullary function objects as tasks. The number of threads to run is configurable as a constructor parameter -- this is especially required by the asynchronous HTTP server template, where handlers are queued to be executed. The library is released under the Boost Software License, and is being developed for future submission to the Boost C++ Library. You can download the latest and previous releases from http://github.com/cpp-netlib/cpp-netlib/downloads. Have a great day everyone and I look forward to your very valuable feedback! -- Dean Michael Berris deanberris.com

Boost bug sprint?
by Marshall Clow 19 Nov '10

19 Nov '10

Since we're now at November 13th, and I originally proposed starting the bug sprint "after the 1.45" release, and "On November 15th", I think that something's gotta give. So, I'm proposing that we start the bug sprint on Saturday, November 27th, and run through Sunday, December 5th (9 days, two weekends, one work week). That way people who work on boost as part of their day jobs will have a full week to participate, while those who do "nights and weekends" will have plenty of time as well. What does everyone think? -- Marshall

LLVM license compatibility with BSL
by vicente.botet 19 Nov '10

19 Nov '10

Hi, I have found quite useful to adapt the test for llvm/libc++ ratio/chrono to test Boost.Ratio and Boost.Chrono. But Anthony has signaled me that maybe there is a compatibility problem with the license included in these files. //===----------------------------------------------------------------------===// // // The LLVM Compiler Infrastructure // // This file is distributed under the University of Illinois Open Source // License. See LICENSE.TXT for details. // //===----------------------------------------------------------------------===// Is the LLVM License (http://llvm.org/docs/DeveloperPolicy.html#license) compatible with the Boost Software License? Can we include files with this comment on a Boost library? Best, _____________________ Vicente Juan Botet Escribá http://viboes.blogspot.com/

What's so cool about Boost.MPI?
by David Abrahams 18 Nov '10

18 Nov '10

Just wanted to call some attention to this article I wrote about Boost.MPI: http://daveabrahams.com/2010/09/03/whats-so-cool-about-boost-mpi/ I think it might be useful to link that from the Boost.MPI docs, too. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

[Probing interest] -- automatization of writing predicates.
by Petr Pilař 18 Nov '10

18 Nov '10

Hi folks, I often find myself in a situation where I need a simple comparison predicate for filtering, look-up, etc. Writing such predicates can get tedious over time and adds unnecessary "bloat", especially when you use the predicate only once. For that reason I have automated this process and I'm interested whether others might find it useful as well. Usage example: auto_predicate(&ClassName::getter, compareWithMe) -- this returns functor which compares the returned value with compareWithMe using == operator. auto_predicate(&ClassName::getter, compareWithMe, comparator) -- this returns functor which compares the returned value with compareWithMe using the given comparator. (Note: getter return type does not have to match compareWithMe type have you supplied comparator with proper signature.) Best regards, Petr Pilař.

Boost.FileSystem dependency on Boost.System
by Matthew Gwynne 18 Nov '10

18 Nov '10

Hi, It seems when compiling anything using Boost.FileSystem that the Boost.System library is also linked. Is this always the case? I can't see any clear documentation of this on the Boost.FileSystem page. If this is the case, is there a nice list of all such dependencies somewhere, as this is currently causing us certain issues? Thanks! Matthew Gwynne http://cs.swan.ac.uk/~csmg/

for_each abstraction
by Karsten Ahnert 18 Nov '10

18 Nov '10

Hi, I need something like an abstraction layer for iterations over some range. Consider for example the following three statements, which all do the same, but the loop inside each for_each is different: // thrust is an STL-like interface for CUDA [1] thrust::device_vector< double > a1( 3 ); thrust::for_each( a1.begin() , a1.end() , op() ); std::vector< double > a2( 3 ); __gnu_parallel::for_each( a2.begin() , a2.end() , op() ); std::vector< double > a3( 3 ); std::for_each( a3.begin() , a3.end() , op() ); //maybe even fusion::vector< double , double , double > a4; fusion::for_each( a4 , op() ); Is there a way or some part of a boost-library which handles the above three statements in a unique manner? I want to write algorithms which are independent of the specific for_each implementation. Best regards, Karsten [1] http://code.google.com/p/thrust/

[config] macro for unified initialization syntax?
by Eric Niebler 17 Nov '10

17 Nov '10

Is there a config macro for the presence/absence of C++0x uniform initialization syntax? http://en.wikipedia.org/wiki/C%2B%2B0x#Uniform_initialization If not, I suggest BOOST_NO_UNIFORM_INITIALIZATION_SYNTAX. A quick test shows that gcc-4.5 in 0x mode has it. -- Eric Niebler BoostPro Computing http://www.boostpro.com
