[test] SIGPOLL not defined on FreeBSD?
by John Maddock 27 May '08

27 May '08

If possible I'd like to see a fix for: http://tinyurl.com/3uz5xg Looks like we just need to add FreeBSD to the list of OS's that don't define SIGPOLL at the start of execution_monitor.ipp. The strange thing is, the other FreeBSD tester doesn't fail here... anyone know what the difference is between them? Both define XOPEN_UNIX to be -1 so they're both advertising that they *don't* support this XSI-specific feature. Come to that are these symbols all macros? Could we just check for defined(SIGPOLL) ? Cheers, John.

It would have been good to include those in your original post. When you said, "But actually this is precisely the most compelling thing about the library - it reduces code that traditionally can be quite difficult into fragments such as those shown," I wondered if that meant you had developed an alternative approach. It isn't clear to me how what you have is better than what is already in Boost. From what you've said I guess it is more flexible, but it isn't obvious to me how. You could also consider integration with http://s11n.net. Regards, Brian Wood Ebenezer Enterprises www.webEbenezer.net

[filesystem] Make basic_path more generic?
by Alexei Alexandrov 26 May '08

26 May '08

Hi, in several places I need to have code which works both with char and wchar_t. Those are template functions. I also work with paths there so I wanted to actually write something like template <typename CharType> void foo(const std::basic_string<CharType>& s) { typedef fs::basic_path<std::basic_string<CharType> > path_type; ... } but it turned out that I can't do it because 1) basic_path has the second Traits template parameter mandatory and 2) this Traits parameter has actually different type for path and wpath: struct path_traits; typedef basic_path< std::string, path_traits > path; // ... struct BOOST_FILESYSTEM_DECL wpath_traits; typedef basic_path< std::wstring, wpath_traits > wpath; Of course, I can easily workaround it with my own traits, but I wonder could it be in the first place like: template<class String> class basic_path_traits; template<class String, class Traits = basic_path_traits<String> > class basic_path; with basic_path_traits being specialized for std::string and std::wstring and fs::path and fs::wpath being just typedef basic_path< std::string > path; typedef basic_path< std::wstring > wpath; ? Thanks. -- Alexei Alexandrov

> If you can find out about any compilation error on VC++9 > I can try a blind fix. <http://lists.boost.org/mailman/listinfo.cgi/boost>Hmm. It seems the msvc compiler & linker (cl.exe) does not want to do *anything* at all when executed outside of the Visual Studio 2008 Command Prompt. It does not even respond to /HELP or /VERSION. Anyway, compiling the coroutine library from inside the VS08 Command Prompt worked fine just now. There should be no need to fix anything. Regards, Thomas K.

Volunteer request: CMake-based build system for Boost
by Doug Gregor 26 May '08

26 May '08

A small group of volunteers has been working on a new build system for Boost based on CMake, a cross-platform, open-source build system. We have reached the point where our core build system has become relatively stable, and we are requesting volunteers to help us improve the build system further by improving the documentation, implementing new features, porting the system to other platforms, etc. We are most interested in volunteers who are: * Willing to learn the CMake build system and the Boost-specific macros we have built for CMake * Interested in the technical challenges of building, testing, and deploying Boost * Able to test on a variety of platforms and compilers * Willing to write as much documentation as code (or more!) * Unwilling to participate in build-system flame wars Anyone interested in joining this effort should read about CMake and our CMake-based build system for Boost (links below), then join the Boost-CMake mailing list (also below). To get a sense of the kind of deployment options we would like CMake to provide in the future, please download the CMake-generated binary installer for Windows, linked below, and direct comments to the Boost-CMake mailing list. Please note that we are not proposing to replace the existing bjam- based build system in Boost. The CMake-based build system will be developed alongside the existing build system. We will not speculate regarding any future Boost policy decisions regarding build systems. Useful links: CMake: http://www.cmake.org Boost-CMake documentation: http://svn.boost.org/trac/boost/wiki/CMake Boost-CMake mailing list: http://lists.boost.org/mailman/listinfo.cgi/boost-cmake Binary installer for Windows: http://www.osl.iu.edu/~dgregor/boost-1.35.1-vc8.exe - Doug

Help appreciated. I cannot either :) I have to double check this when I'm fresh in the morning, but this Derived stuff looks like a letfover from some internal refactoring of the code. I know I shuffled things a lot around the iterator code in order to keep it generic enough and modular enough to easily plug the safe mode layer, and the Derived parameter could have been part of some of the earlier attempts to design the architecture. Thanks for spotting this, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Hi John ! I've reverted parts of http://svn.boost.org/trac/boost/changeset/45645 because "has_long_double_support.cpp" is missing from trunk (and this breaks regression testing) On Thursday 22 May 2008, john(a)johnmaddock.co.uk wrote: > Author: johnmaddock > Date: 2008-05-22 07:23:57 EDT (Thu, 22 May 2008) > New Revision: 45645 > URL: http://svn.boost.org/trac/boost/changeset/45645 > Modified: trunk/libs/math/build/Jamfile.v2 > ===================================================================== >========= --- trunk/libs/math/build/Jamfile.v2 (original) > +++ trunk/libs/math/build/Jamfile.v2 2008-05-22 07:23:57 EDT (Thu, > 22 May 2008) @@ -49,6 +49,8 @@ > sph_neumann > ; > > +compile has_long_double_support.cpp ; See http://svn.boost.org/trac/boost/changeset/45665 for details.

Question regarding logging persistence thread communication network messaging and async frameworks
by Scott Woods 25 May '08

25 May '08

(Note: Apologies if there have been multiple copies of this mail. From my end posts to this list have not been getting through. This last attempt is after re-subscribing to the list) Hi, Is there a place in Boost for a library that tackles everything in the subject line? I believe the realistic answer is no but I would be happy to be proven wrong. Work in the different areas mentioned in the subject line recently collapsed into a single underlying technique. Given the example UDT below; struct person { std::string name; std::vector<unsigned> score; std::set<string> team; }; persistence is achieved using; person new_member; codec_object<person> configuration( "profile" ) configuration << new_member; // Save in a disk file name "profile" configuration >> new_member; // Load from the same disk file transmitting the same object between threads looks like; send( new_member, other_thread ); while receiving that transmission occurs in code that looks like; my_thread::received( person &new_member ) { .. } Transmission of messages across networks looks like; send( new_member, socket_proxy ); Yes, its the same as for inter-thread communications. The "socket_proxy" just happens to be a variation on "my_thread" that forwards materials it receives onto a socket connection. Logging looks like; WINSOCK( socket, AF_INET << SOCK_STREAM << 0 ); COMMENTARY( "connection to " << address_entered << " failed (" << failure << ")" ); Logging messages can be routed anywhere based on the type and unique identity of the originating party. The fragments of code provided above hide a lot. While that's technically desirable I can appreciate that it might not flesh out my question at all (i.e. ...room in Boost). But actually this is precisely the most compelling thing about the library - it reduces code that traditionally can be quite difficult into fragments such as those shown. The actual implementation of the "send" primitive appears below; // from a header class active_point { void send( type_hash, network_variant &, point_id ); template<typename S> void send( const S &s, point_id a ) { if( !a ) { return; } send( type_of<S>::hash(), network_variant() << s, a ); } // from the related cpp void active_point::send( type_hash h, network_variant &nv, point_id a ) { network_variant s; network_memory::iterator i = network_output<3>()( s ); *i++ << h; i++->swap( nv ); *i++ << self; point_register().send( s, a ); } This is only provided to give a tiny bit more substance to my code fragments. The catalyst for my question is that this work is about to be shelved. If any part of this work could be a contribution to Boost then that is much better (from my POV) than nothing. Of course there has to be a place for it and it has to pass the wonderfully rigorous Boost review process. Some of the technical selling points; * basic async model is taken from SDL (system description language). * the technique is non-intrusive; e.g. it is possible to "send" instances of types from third-party libraries * externalized data (i.e. in disk files and on network connections) is subject to formalized encoding/decoding * the technique appears to be reasonably efficient - certainly no worse than code it replaced. * the technique copes with the storage and transmission of arbitrarily complex C++ objects, easing design constraints * the technique removes the need for data translation (i.e. the code that appears around SQL servers, Windows registry and DCOM). I appreciate that Boost already has components that solve different parts of the same puzzle. Those components are major contributions to C++ that I am not trying to compete with. If there is anything of value in what I have, I suspect it's in achieving the trilogy; persistence, thread communications and network messaging with a single unifying technique. Any questions welcome, Scott.
