[BGL] Why not bf and df iterators (graphs vs trees)?
by nicola 27 Jun '06

27 Jun '06

Hi all, the following is just a curiosity of mine, about which I would like to get some comment. On browsing a few discussions about generic tree libraries, I got the impression that many people judge that pre-/in-/post-order iterators, and alike, are essential in any tree class or container (concept). My opinion is that a generic tree class (I refrain from calling it a "container", because in my mind a tree does not necessarily model a Container concept) should be designed much more after the BGL than after the STL containers. One design choice in the BGL is that there are "visitor" functions, e.g. breadth_first_search() and depth_first_search(), but there are no "bfs_iterator" or "dfs_iterator". What are the motivations that lead to such choice? Might they be applied to trees as well? As a simple example in favor of the former approach, a "BGL-like" tree data structure would allow a user to use a std::vector as a heap (by overloading the suitable functions). I know that for the SoC several tree libraries have been proposed. Is there no room or interest for other proposals any longer? Is it possible to take a look at those proposals? Regards Nicola

asio versus MSVC

Hello, On http://asio.sourceforge.net/ among the listed supported systems/compilers is Win32 using Visual C++ 7.1 and Visual C++ 8.0. Are there plans to support Visual C++ 6SP{5,6} also? What are the difficulties/obstacles for this to happen? Greetings Franz

Spam filter policy?
by Rene Rivera 27 Jun '06

27 Jun '06

Recently I've been getting anti-spam challenge-response emails from some subcribers on the Boost list. Personally I find such emails on a public list rude. Do people expect everyone on the list to register onto their respective anti-spam filters? I for one won't. It just means that person will never get many of the communications going on in the list. Since I'm now filtering email through Google, most likely I'll just mark such emails as SPAM and eventually the persons will never see Boost email again. But that sounds rude on my part. Any suggestions? -- -- 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

[release] Bad merge?
by Rene Rivera 27 Jun '06

27 Jun '06

Something strange is going on, or went on, recently with CVS. The Jamfile.v2 on the RC_1_34_0 branch is no longer in a branch, and has the wrong version number on it (1.35.0 instead of 1.34.0). This is easy enough to fix, but I'm afraid this might be an indication of an errant merge of code, or of the branch somehow getting reset/moved. Whomever has been doing recent checkins to CVS please verify your changes on the branch and fix any problems ASAP. -- -- 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

Bug in serialization example /boost/libs/serialization/example/portable_binary_oarchive.hpp
by Stefan van den Oord 26 Jun '06

26 Jun '06

Hi, According to the boost web site, this mailing list is the preferred way to report bugs, so I subscribed and send you this: I believe the example /boost/libs/serialization/example/portable_binary_oarchive.hpp doesn't work correctly. On my platform, Mac OS X, the endian conversion is performed. For a small negative number (say -42l), the endian conversion results in a big negative number (-687865857). The size, however, is computed _before_ the endian conversion, so it is 1 (one) in this case, which is not high enough to hold the converted long. I guess the solution is to do the endian conversion first, then the size computation. That seems to work for me. Based on the 1_33_1 sources, my version of save_impl is now: void save_impl(long l){ // we choose to use litle endian #ifdef BOOST_BIG_ENDIAN char * first = static_cast<char *>(static_cast<void *>(& l)); char * last = first + sizeof(l) - 1; for(;first < last;++first, --last) { char x = *last; *last = *first; *first = x; } #endif long ll = l; char size = 0; do{ ll >>= 8; ++size; }while(ll != -1 && ll != 0); os.put(size); save_binary(& l, size); } I hope this helps in improving the example. Regards, Stefan van den Oord

[tuple] or [fusion::tuple]: feature request
by Oleg Abrosimov 26 Jun '06

26 Jun '06

Hello dear authors of boost tuple libraries! I've a need to implement a function that gets a tuple of manipulators and applies them to stream: template <typename T, typename Tuple> std::string string_from(T const& t, Tuple const& manip) { std::stringstream ss; ss << manip << t; return ss.str(); } usage of this function would be: std::string s = string_from(1.2, boost::make_tuple(std::setprecision(2), std::scientific)); The problem is: how I can efficiently suppress output of left/right/delimiter strings? Of cause, with fusion::tuple I can do the following (manipulator names are taken from boost::tuple docs, though): template <typename T, typename Tuple> std::string string_from(T const& t, Tuple const& manip) { std::stringstream ss; ss << set_open("") << set_close("") << set_delimiter("") << manip << t; return ss.str(); } but it has a lot of overhead in tuple's output iterator that should be avoided for me. I feel that the best solution would be to have a function "print_tuple(stream, tuple)" in tuples library that just do what I want. One more issue with fusion::tuple manipulators as they are in boost 1.33.1 (unofficially): I've discovered that only narrow strings and characters are supported. am I right? If so, I believe that wide versions should be added too. Best regards, Oleg Abrosimov.

I was also thinking about that - something about re-assign?! > There's also the problem of the error asio::error::eof, which > corresponds to a real error on Windows, but is synthesised on > POSIX platforms. What about adding EEOF -1 (or so) inside error_code.hpp and apply a switch-statement inside system_message? regards, Oliver
