How to obtain old files from Boost.Vault?
by Markus Werle 06 Oct '06

06 Oct '06

Hi! In <http://groups.google.com/group/boost-list/browse_thread/thread/ 404f6a4eb1f13ed1/fe070423d5945258?q=SVD++ublas&lnk=nl&hl=en&> Le Farfadet Spatial explains that he has uploaded a file inverse-01262005.tar.gz with code under boost license to the vault (see bottom of page). Maybe I am stupid or maybe the vault is not a place for stuff to last forever: I failed to obtain this file. Also google fails here <http://www.google.com/custom?q=inverse&hq=site%3A www.boost-consulting.com+inurl%3A www.boost-consulting.com%2Fvault&search.x=0&search. y=0&cof=LW%3A277%3BL%3Ahttp%3A%2F%2F www.boost.org%2Fboost.png%3BLH%3A86%3BAH%3A center%3BGL%3A0%3BS%3Ahttp%3A%2F%2Fwww.boost.org% 3BAWFID%3A9b83d16ce652ed5a%3B&sa=Google+Search&domains= www.boost.org%3Blists.boost.org> So I have some questions: 1. Could someone point me to a place where this file still can be found? 2. If the vault is just a bin to put stuff that gets deleted later how can we (as community) avoid to loose the ingenious stuff that enters that place and keep it forever? I haste to download all that might be of interest for me, but sometimes I cannot foresee what might get interesting in some years. Also the quality of the code posted to the vault is rather high, so probably a bit more data persistence is quite appropriate, isn't it? regards, Markus

Hi, I don't get why I'm getting diferent results with this regexp in perl and in boost::regex, is there something I'm doing wrong? regards echo " text/html; charset=iso-8859-1" | perl -wne 'if(m#([^/;]+/[^/;]+)#) { print $1."\n" }' http://rafb.net/paste/results/jrUGyO97.html -- Pedro Larroy Tovar, pedro at larroy dot com | http://pedro.larroy.com/ * Las patentes de programación son nocivas para la innovación * http://proinnova.hispalinux.es/

[multi_index_container] Thread safety
by Prashant Thakre 05 Oct '06

05 Oct '06

Hi, As per the section "Complexity and exception safety": Iterator and reference validity is preserved in the face of insertions, even for replace and modify operations. Would it be safe to insert() from within two or more threads simultaneously ? Assumption being that the keys inserted will be always be different. -- regards, Prashant Thakre

graph-tool and boost/random
by Jens Müller 05 Oct '06

05 Oct '06

I cannot compile graph-tool on amd64/gcc4.1.1/Gentoo and Boost 1.33.1, while Tiago can with the same gcc. Maybe someone can take a look? See http://news.gmane.org/gmane.comp.science.graph.graph-tool.general/cutoff=9 ...

Problem with boost serialization with an existing 'struct load'
by Jeff Epler 05 Oct '06

05 Oct '06

Please send me a copy of any replies to this message. The following code compiles with boost_1_31_0 but fails with 1_32_0 and 1_33_1 (tested with gcc 3.2.2 and gcc 4.0.3 on Linux systems): // ------------------------------------------------------------------- #include <boost/archive/xml_iarchive.hpp> #include <boost/serialization/vector.hpp> #include <boost/serialization/split_member.hpp> #include <iostream> struct K { friend class boost::serialization::access; template<class Archive> void save(Archive &ar, const unsigned int version) const {} template<class Archive> void load(Archive &ar, const unsigned int version) {} BOOST_SERIALIZATION_SPLIT_MEMBER() }; struct load { int x; }; int main(void) { std::vector<K> v; boost::archive::xml_iarchive ia( std::cin ); ia & boost::serialization::make_nvp("v", v); return 0; } // ------------------------------------------------------------------- We would like to move our application from boost 1_31 but this problem with 'struct load' has stopped us so far. Is this a bug in BOOST serialization in 1_32 and 1_33 that will be corrected in the future, or do we have no choice but to rename our 'struct load'? If this is the correct behavior of the serialization library, is it noted anywhere in the documentation? I was unable to find such a note. Jeff

Bug? lambda+function composition not working together
by Johan Torp 05 Oct '06

05 Oct '06

Operator , (nullary composition) does not seem work between boost::function and boost::lambda. Is this a bug? Is there any way to work around this? void foo() { std::cout << "foo"; } boost::function<void()> f(boost::lambda::bind(&foo)); (f,f)(); // Outputs foo (boost::lambda::bind(&foo),f)(); // Outputs foo (f,boost::lambda::bind(&foo))(); // Outputs foo (boost::lambda::bind(&foo), boost::lambda::bind(&foo))(); // Outputs foofoo I am using boost 1.32 and gcc 3.4.4.

Boost string allocator
by Thompson, Ian 05 Oct '06

05 Oct '06

Hello, I have recently used the fast_pool_allocator as the allocator for std::map with excellent results wrt performance. My application also uses a lot of strings (basic_string) and I was seeking some advice on changing the basic_string allocator to a "boost allocator" . Can anyone offer some advice in this regard?

Using ofstream with xml_oarchive to write a file larger than 2GB

Many don't by default. Can you create a large file (using dd, for example) in the shell? (I'm assuming you're using some flavor of Unix here...) - James Jones Administrative Data Mgmt.

[Smart Pointers] Casts for shared_array
by Christian Henning 04 Oct '06

04 Oct '06

Hi there, don't know if this ever came up. I could not find anything in the archives. I would like to cast a shared_array<POD> into shared_array<unsigned char>. Since there is no operator for that I wonder what the reason is? Thanks, Christian
