I have auto test cases that can take fixtures whose members they access in a uniform way. Say struct F1... Fn BOOST_FIXTURE_TEST_CASE( test_case1 , F1 ... Fn ) { //same code for all Fi } Is there a way to do this? Regards,

Boost Test - Customize output.
by mik 08 Jul '09

08 Jul '09

Hi all, I'm using Boost::Test to build a regression test of a library and it's working well. But I'd like to customize the output. For example, I get: c:/REPOSI~1/Stable/pdglib/libs/forex/OPTION~1/test/src/option_test_case.cpp(83): error in "option_test_case::regression": american (38) - reference lib (foreign_rho): -1.#IND new lib (foreign_rho): 0 The information about the file and number of line are unnecessary. How can I suppress it? And is it possible to customize the final report too? Thank you, Mirko Cambi

functional/hash and mp_math weirdness
by Andrea Bedini 07 Jul '09

07 Jul '09

Hello, I'm experiencing troubles with functional/hash #include <boost/functional/hash.hpp> #include <boost/mp_math/integer.hpp> typedef boost::mp_math::integer<> big_integer; class A { friend A operator*( const big_integer& lhs, const A& rhs ) {} }; gives the following madness. What surprises me is that I am not making any use of functional/hash (in the actual code, it gets included from boost/unordered_map.hpp), as the error messages don't indicate any line of my code. I think mp_math is not playing a big role here, once I had the same problem with a homemade class (but unfortunately I can't now replicate the same conditions). Can anyone explain me what is going on here ?

[test] How do run a specific test suite?
by Christian Henning 07 Jul '09

07 Jul '09

Hi there, I believe I once read that one can specify test suite to be run as a command line parameter. By default all test suites are running, but, the user should be able to specify one in the case there are several suites. I've tried to look up that information inside the boost::test documentation but couldn't find it. Am I wrong that such functionality exists? Regards, Christian

[Asio]How to peocess signal with asio?
by sjdf 07 Jul '09

//---------------------------------------------------------------------------- // Hi all, // I have a program like below. // Two questions: // 1.

[Range.Ex / String.Algo] Ambiguous call to overload function "find"
by 梁绍池 07 Jul '09

07 Jul '09

I use vc 9.0 to compile the following code with boost 1.39.0 and range_ex. #include<string> #include<boost/algorithm/string.hpp> #include<boost/range/algorithm.hpp> int main() { std::string s = "hello"; boost::find_first(s, "lo"); return 0; } The compiler will complain ambiguous call to overload function "find". I found there's also a "find" in boost/range/algorithm.hpp. Even worse when I change the type of "s" to const std::string, the compiler will resolute "find" call as the one in boost/range/algorithm.hpp and reports an error "const_iterator is not a member of std::_String_const_iterator". Now I just indicated the "find" call in boost::find_first explicitly. Is there a better way to solve it? Thanks! S.C. Leung

Boost ASIO - SO_LINGER Socket option is not working
by Nick Aschberger 07 Jul '09

07 Jul '09

Hi All, I have a situation where at termination of my program, I am closing my socket, and then deleting the socket object. Note, we are using non-asynchronous (blocking) accesses at this point, boost is version 1.36. In some cases, the socket has had some data written to it, but that data is never received by the connected client - because I destroy the socket before the data is sent. So, SO_LINGER is the socket option that is supposed to solve all my worries (it should wait on close for any unsent data to be sent), however I am using it and there is no effect. I presume because I'm doing something wrong. Here is my psuedo-code flow: /* Creation of socket */ m_socket = new boost::asio::ip::tcp::socket(m_io_service); /* Connect the socket with something like: */ acceptor.accept(*m_socket, error); /* Set SO_LINGER option on connected socket */ boost::asio::socket_base::linger linger_op(true, 2000); m_socket->set_option(linger_op); /* program executes, does some stuff */ /* At termination */ // close the socket m_socket->close(); delete(m_socket); I experimented with m_socket->shutdown() instead of close, and it made little difference. In fact, from the documentation it seems shutdown() is the one I definitely don't want to call, as close() is supposed to wait for data to be sent. If anyone has some suggestions as to what would be correct, I would much appreciate it. cheers Nick Aschberger

[pool] singlton_pool::malloc returning bad address
by Jonathan Leonard 06 Jul '09

06 Jul '09

Hi all, In a long running process on Windows, I'm seeing singleton_pool::malloc eventually return addresses such as 0x100f34b0 (which in this case [according to vmmap] is an address into a 'read-only' section (.rdata) of a DLL which was loaded for 'execute/copy on write'). The system [rightly] barfs at the request to write to that address. Anyone have an idea what could be going on here? Many thanks, Jonathan

Licensing issues for boost users
by Avi Bahra 06 Jul '09

06 Jul '09

I am trying to understand the boost licensing in terms of users of boost. Is there any where I can find out additional information about this ? For the project I am working on, we will only ever* use* boost, are there an licensing issues/restrictions for *users* of boost ? Am I right is assuming that boost software license only applies to organization that contribute to boost, and not users? i.e I am assuming that users of boost do not need to embed the boost license in our own code that uses the boost libraries ? in essence we are free to license/copyright our own code in any manner, even though it uses boost? Any help in this matter would be greatly appreciated. Avi

Using iostreams to serialize into and from a memory buffer
by Ivan Gonzalez 06 Jul '09

06 Jul '09

Dear all, I have some numerical data in my code that I'm saving to a file. My code loops thousands of times generating a set of this data in each loop step. The data is reused within the same step but there is no need to save it to the next one. Currently I'm using the serialization library to write all the data to a binary file (using the optimization for contiguous arrays) and then read it. I thought (maybe naively) I could increase performance keeping the data in memory instead of write/read to disk. I came across this post http://lists.boost.org/boost-users/2008/05/36235.php where how to serialize into/from a memory buffer using boost::iostreams is explained. However I found that using the solution in the post is way slower than write/read to disk. In fact modifying the code in the post to use std::ofstream and std::ifstream open with the std::ios::binary flag makes the code 5 times faster. Am I missing something or is it right that the iostream solution is slower ?. (I understand that sometimes you don't have the option to write to a file, but is this the fastest way to use a memory buffer ?) Thanks in advance, Ivan

Request for generalized `overview' documentation
by tom fogal 05 Jul '09

05 Jul '09

Hi all, I'd like to put in a request for an additional kind of documentation to be distributed with boost. Current boost documentation, I would argue, is very good at answering questions of the form, 'How can I get Boost.X to do functionalityA?' It is not so good at answering the question, 'How can I obtain functionalityA?' To make a long story (somewhat) short, especially when one wants to do something relatively simple and limited, many boost libraries might be able to fill the role. Today's problem is providing a callback mechanism. A simple freestanding function would work fine. Yet at some point, I know somebody is going to wish they could pass a member function, and then someone else will want to pass any object that implements operator(), and then ... There are multiple libraries which I might use to fulfill this goal. What's lacking is a way to (quickly!) figure out which one I want. >From limited skimming, it seems like Boost.Function might do what I want. However, I might consider that a future use case would allow multiple functions to get called from a single callback `site', which would cause me to choose Boost.Signals. If I'm concerned with thread safety, it seems like I might choose Boost.Signals2. I think Boost.FunctionTypes might fit in here somehow too, but I'm still not sure. In this case, I'm concerned with compilation time, but execution time is not likely to be important. It seems like the only way I could determine which library fits best given that restriction is to implement a few simple programs. Given today's inquiry, a short blurb like the following would go a long way: Boost.X grew out of frustrations implementing nitz-frobbing in terms of Boost.Y. Along the way, it was discovered that X provided a natural vehicle for standardizing foo-like syntax such that compile-time errors could be generated in the bar case. The price paid for the ability to easily frob your nitzes is memory. X must store 16 additional words of state for every nitz to guarantee an O(log n) traversal of a nitz-holding container (it's actually 2*log n due to the requirement of identifing the internal node with the highest stitzel before the frobbing can start). Note: Boost.Z provides an alternative methodology for foo-ing which adheres to the SomeConceptA protocol (which X does not). There's an incredible amount of useful information here. If Boost.Y looked relevant before, I could presumably decide if I should go with that based on whether I think I'll need to frob the nitz in the future. Presumably looking at the 30-second blurb from Y and Z would let me reason out which library I would want for foo-ing. The performance characterization gives the information I need to choose between implementations with a good O() versus, say, implementations which will fit all of my nitzes in cache on my most important platform. You might also think of an alternative form, which categorizes Boost libraries and provides a `category introduction' to overview them. Given the somewhat distributed nature of Boost libraries, I figure a blurb per library is easier, but from a user's perspective I'm not convinced it matters. Thanks for reading, -tom

Fw: xpressive app question

(Resending from the correct email address.) ------Original Message------ From: Eric Niebler To: biolaser To: boost-users(a)lists.boost.org ReplyTo: eric.niebler(a)gmail.com Subject: Re: xpressive app question Sent: Jul 4, 2009 12:03 PM (Apologies for the top-post. Darn Blackberry.) Hi William, In the future, please send end user questions about Boost libraries to boost-users(a)lists.boost.org. Xpressive grammars with semantic actions have all the power to build any kind of parser you need, context-free or otherwise. I think it will work well for you. Another option to consider is Boost.Spirit, which is designed with the lex/yacc scenarios in mind. It is a very powerful parser generator, but without xpressive's dynamic grammar facilities. If you go that route, I'd recommend Spirit2, which is still under development but very usable, clean and powerful. Good luck, -- Eric Niebler BoostPro Computing www.boostpro.com From: "biolaser" Date: Fri, 3 Jul 2009 20:22:26 -0600 To: 'Eric Niebler'<eric.niebler(a)gmail.com> Subject: xpressive app question Hi Eric, I’ve been looking through the xpressive documentation and I’m very, very impressed. You’ve approached the creation of this system with astounding energy, a very wide pragmatic view of things, and great intelligence and foresight. I really hope xpressive will be suited for my needs. I’m desirous of creating a language (collection of grammars or tokens) that will be incorporated into a runtime for a report-writer engine I’m developing. The user will task the engine via this custom language. In the past I used lex and yacc extensively for similar projects. As you know, yacc facilitates the creation/recognition of a custom language (by defining patterns which contain various grammars (tokens)) and lex facilitates the creation/recognition of the individual grammars (tokens) themselves. Will xpressive facilitate the creation/recognition of a custom language by letting me define patterns of grammars? Or will I need to code that logic myself, as respects recognizing a collection of grammars to form certain complete language patterns? I hope I have posed my question clearly enough. If xpressive is not well suited to the higher level pattern-recognition tasks, is there something else that is yacc-like that will serve that purpose and that will work well with xpressive? Thanks for your help, William Stroupe

And can I use: bind(&std::pow,constant(-1),bind(&IIPrimemap::size,var(primemapvec))); in the program? where : typedef std::pair<int, int> IIPrimepair; std::vector<IIPrimepair> primepairvec; Can anyone with kindness help me?

[Please do not mail me a copy of your followup] <http://legalizeadulthood.wordpress.com/2009/07/05/c-unit-tests-with-boost-t…> In Part 2 of this series, I discussed the assertion facilities of Boost.Test and how to get the first passing test on Bob Martin's Prime Factors Kata. In this part, I will continue with test-driven development to complete the functionality of the PrimeFactors::Generate method. Please post comments on the blog.

[Please do not mail me a copy of your followup] <http://legalizeadulthood.wordpress.com/2009/07/05/c-unit-tests-with-boost-t…> In Part 1 of this series, I discussed how to setup a basic C++ unit test project that executed the unit tests when you built your code. In this part, I will discuss the assertion framework provided by Boost.Test in the context of a simple programming exercise that demonstrates test-driven development. Please post comments on the blog.
