[BGL] IncidenceGraph and out_edges
by Christian Bähnisch 20 Jun '09

20 Jun '09

Hello, I do a repost here because of a silly subject copy and paste error of me, sorry for that! The text of my original message is: I'm trying to implement the IncidenceGraph concept for an non-BGL undirected graph like datastructure. Following the boost documentation the target function used with edges from out_edges(u,g) must give vertices != u. Can somebody please explain me why this requirement is in BGL! I think it can make the adaption very difficult as it requieres to artificially … [View More]

[Q] serializing Database Null values (design question)
by V S P 20 Jun '09

20 Jun '09

I have my CPP ORM pretty much working (so that I can read data from the database and serialize it with boost serialize) in generic manner. There is an issue however with 'Nulls' that possibly exist in the database. I use underneath OTL c++ db library and it has a 'null indicator' like many db libraries do. So if I see a value where null indicator is set to true, should I serialize it out and if yes -- is there something like 'NaN' for all the different value types defined? or should I skip … [View More]

[Q] reading back serialized Collection of shared_ptr
by V S P 20 Jun '09

20 Jun '09

I made may be a little more headways since my previous question and now have an xml archive that appears to 'denote' the shared pointers (see below) To do this I found and used boost template function specifically for shared pointers -- a data member of myclass inheritin from std::multiset -- TRow is the Value type of the multiset that implements 'serialize' method -- -- struct { template <typename Archive> void serialize (Archive& ar, const unsigned int version)const { … [View More] for(tThisClassConstIterator it=this->begin(); it!=this->end(); ++it) { boost::serialization::save<Archive,typename TRow>(ar,*it,version); } } tTEST_TB3 now however I do not understand how to 'deserialize this' The basic call to void load_table (tTEST_TB3& t, const char * filename) { // open the archive std::ifstream ifs(filename); assert(ifs.good()); boost::archive::xml_iarchive ia(ifs); ia >> BOOST_SERIALIZATION_NVP(t); } does not even compile, I suspect it is because when this 'serialize' function on tTEST_TB3 is called, now the boost::serialization::save<Archive,typename TRow>(ar,*it,version); is NOT valid, because the ar is of type iarchive, and save function on the shared_ptr is not defined for 'iarchive', only for oarchive. So there is another function in the same boost header file ( #include <boost/serialization/shared_ptr.hpp> ) that defines a 'load' function for the shared ptr However -- what I do not undestand is how to invoke this function it seems like I have to iterate through every entry in the archive and then call load to read it into a shared ptr? That seems to be contrary to all the other mechanism supported by the Serialization library. The basic examples just say that I can take a container and just shift it in (or out) of Archiver -- but that does not work if the container is of shared pointers. That's why I went the route of iterating through every element of the container to serialize, and not do not undestand how to load it back. So I need some help (I can provide the complete example if needed) thank you in advance ---------- <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="5"> <t class_id="0" tracking_level="0" version="0"> <px class_id="1" tracking_level="1" version="0" object_id="_0"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_1"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_2"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_3"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_4"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_5"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_6"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_7"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_8"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> <px class_id_reference="1" object_id="_9"> <otrq_prov_id>1245439719</otrq_prov_id> <clnt_dbid>1245439719</clnt_dbid> <mydate>6/19/2009 15:28:39</mydate> <amount>33222112121.212000</amount> </px> </t> </boost_serialization> -- V S P toreason(a)fastmail.fm -- http://www.fastmail.fm - Send your email first class [View Less]

Hi, I have created an extension boost python module for C++ class, successfully using Visual Studio 2009, and get a shared library(.dll) as output.

I have explicitly tried importing the dll as resource in an Eclipse PyDev project, and also set in windows PATH environment variable, the location for this dll. With the PATH set, I also tried import from the python shell, but no success. Can someone describe what is the process … [View More]

Hi folks, Sorry for the confusion i've caused. It was a problem in my projects include-path, not with the include-path of gcc itself. I included files from another library i use, and this library contains a file named "assert.h" - why it was named so that it clashes with the system-assert i don't know. I renamed this file and altered it's #define include-guards. Now everything works.

Hello. I would like to know if it's possible (or there's any trick) to connect to ipod touch via boost.asio with ssl encryption. Currently I'm using an ssh connection with libssh. That's ok to navigate the directories, but I cannot copy files, since scp asks me for a password and I don't know how to solve this. Any idea? Thanks in advance.

[docs] Meaning of right/left arrows
by Robert Jones 18 Jun '09

18 Jun '09

A few libraries (eg. fusion) have sufficiently complicated (and thorough) documentation that they have sections, sub-sections, and maybe sub-sub-sections. In that case I instinctively expect that the arrow right at the top right of the page will take me to the next sections, or sub-sections (ie the next peer of the page I'm looking at), whereas in fact it always takes me to the next page. Does anyone else consider this is not quite right, and is it worth changing it? - Rob.

[ptr_container] ptr_map and MinGW: "a declaration of assert must be available", even with cassert included

Hello, I'm using boost::ptr_map successfully on Linux, compiling with gcc 4.3.2. However, now i tried the same code on Windows XP, using MinGW with gcc 3.4.5 i get the following error: "error: there are no arguments to 'assert' that depend on a template parameter, so a declaration of 'assert' must be available". I had exactly the same error on Linux, there i put a #include <cassert> before the #include to boost::ptr_map and everything worked. But on windows, i tried #include <cassert… [View More]

Just a general question, Could one use Boost.Regex to build a Well-Formed and Validating XML parser whose view is iterators to elements inside the XML document? In other words, create a class that acts like an XML parser so that you may derive from it to say create a XMPP class? Etienne

BOOST_FOREACH question
by Zachary Turner 18 Jun '09

Suppose I've got a concrete instance C of some class, and a pair of iterators X and Y representing a range [X, Y). I want to do the following: int a, b, c; while (X != Y) { C.foo(*X, a, b, c); ++X; } I can type it out like that, but actually X and Y are zip_iterators, and it's hard for me to figure out how to parameterize the zip_iterator to instantiate it.

asio: serial ports and timeouts

Hi again I was playing around with asio a bit, creating the following class: AsioPlayground::AsioPlayground() : maxCharDelay(seconds(10)), charTimeout(io, maxCharDelay), port(io, "COM2") { port.set_option(serial_port_base::baud_rate(9600)); port.set_option(serial_port_base::character_size(7)); port.set_option(serial_port_base::flow_control(serial_port_base::flow_control::none)); port.set_option(serial_port_base::parity(serial_port_base::parity::even)); port.set_option(… [View More]serial_port_base::stop_bits(serial_port_base::stop_bits::one)); } AsioPlayground::~AsioPlayground() { } template<> void AsioPlayground::write<string>(const string &value) { boost::asio::write(port, buffer(value, value.size())); } template<> void AsioPlayground::write<char>(const char &c) { boost::asio::write(port, buffer(&c, 1)); } template<> char AsioPlayground::read<char>() { function<void(const error_code &)> onTimeout = bind(&AsioPlayground::onTimeout, this, _1); charTimeout.async_wait(onTimeout); function<void(const error_code &, size_t)> onSuccess = bind(&AsioPlayground::onSuccess, this, _1, _2); char input = '\0'; async_read(port, buffer(&input, 1), onSuccess); error_code ec; io.run(ec); return input; } string AsioPlayground::read(int numberOfCharacters) { string input; for (int i = 0; i < numberOfCharacters; ++i) { input.push_back(read<char> ()); } return input; } void AsioPlayground::onSuccess(const error_code &ec, size_t size) { charTimeout.cancel(); } void AsioPlayground::onTimeout(const error_code &ec) { if (ec != error::operation_aborted) { throw InterfaceTimeoutException("No response"); } } int AsioPlayground::main(const vector<string> &args) { AsioPlayground play; play.write<string> ("/?12345678!\r\n"); try { cout << "Reply: " << play.read(10) << endl; } catch (const InterfaceTimeoutException &ex) { cout << ex.what() << endl; } return 0; } Executing the main function should have an expected behaviour of writing the string to the other party, and reading at least 10 characters or failing with a timeout exception. The timeout is meant to work as a character delay, allowing a maximum of 10 seconds between each transmitted character before failing. The writing part works A-ok. The reading throws the expected exception if no characters are transmitted by the oppositing device. However, if I transmit 9 characters from the device, these characters are displayed, appended by a '\0' character (or whichever character I choose as default in read<char>()). io.run() seems to return immediately, not even waiting for any characters to be transmitted. Adding completion_conditions to async_read(), like transfer_all() or transfer_at_least(1) did not do the trick, either. What is going wrong here?

[ptr_container] Const & non-const ptr_map iteration over mapped values.
by Rodolfo Federico Gamarra 15 Jun '09

15 Jun '09

Hi all!! In my class have an internal member of type typedef boost::ptr_map<int, Component> InternalComponentCollection; I'd like to provide const and non-const iterators, through appropriate two pairs of begin / end methods, in order to have "const Component&" and "Component&" as return type in each of the dereferencing operators. What's the way to do that? What I tried: Since the underlying storage relies in "pair" with a pointer, I thought of using a transform iterator to … [View More]project "second" and then dereference the pointer; something like, for instance, ComponentIterator Begin() { return boost::make_transform_iterator(fComponents.begin(), fResolver); } where fResolver is an instance of template<class T1, class T2, class R> struct SecondResolver { typedef R result_type; template< template <typename,typename> class Pair> result_type operator()(const Pair<T1, const T2>& p) const { return * p.second; } }; and having typedef SecondResolver<KeyType, MappedType, MappedReference> ComponentResolver; typedef typename InternalComponentCollection::key_type KeyType; typedef typename InternalComponentCollection::mapped_type MappedType; typedef typename InternalComponentCollection::mapped_reference MappedReference; typedef typename InternalComponentCollection::iterator PairIterator; typedef boost::transform_iterator<ComponentResolver, PairIterator> ComponentIterator; The case for const iteration is similarly implemented, using the following typedefs: typedef SecondResolver<KeyType, ConstMappedType, ConstMappedReference> ConstComponentResolver; typedef const Component* /* No nested typedef for this...*/ ConstMappedType; typedef typename InternalComponentCollection::const_mapped_reference ConstMappedReference; typedef typename InternalComponentCollection::const_iterato PairConstIterator; typedef boost::transform_iterator<ConstComponentResolver, PairConstIterator> ComponentConstIterator; My remarks about my solution are: 1) SecondResolver is not an "UnaryFunction" in the sense of the C++ standard, since there's no "argument_type" nested typedef. Tough it seems that that isn't actually required by transform_iterator. I have problems in trying to define that typedef (see 2). 2) The actual pairs are instances of boost::ptr_container_detail::ref_pair so it wouldn't be right to typedef that as arg type (it's a "detail"). This class provides implicit conversion from std::pair, but no implicit conversion to std::pair. So that's why I wrote the operator() as a template function, since cannot give the operator an explicit type: nor ref_pair (being a detail), nor std::pair (not having the conversion). Should that conversion be provided? 3) I wrote ConstMappedType typedef explicitly, without relying in a nested typedef in the original class. Doing typedef const MappedType ConstMappedType; doesn't work because the const binds to the pointer, not to the pointed type. Other possibility I looked was to have instead (for the const case, the other one is similar): typedef typename InternalComponentCollection::const_reference ConstReference; typedef SecondResolver2<ConstMappedReference, ConstReference> ConstComponentResolver; template<class RetType, class ArgType> struct SecondResolver2 { typedef RetType result_type; typedef ArgType argument_type; result_type operator()(argument_type p) const { return * p.second; } }; Anyone is better?

[shared_ptr] Member functions as deallocators
by Michael Crawford 14 Jun '09

14 Jun '09

I'm using shared_ptr to hold a SceneManager object. In this particular case, I don't actually want the shared_ptr to have ownership of the SceneManager, but rather take advantage of it to insure that the SceneManager it holds is cleared when the containing object (a game's state) is destroyed. The deallocator needs to call SceneManager::clearScene, but it needs to call it on the held object, so the deallocator call would be essentially (pointer held in shared_ptr)->clearScene( ); Can … [View More]

multi-thread server with boost::asio or boost::thread?
by Matheus Araújo Aguiar 14 Jun '09

14 Jun '09

Hello boost users, I'm currently working on a MMO game server and have been using the boost::asio to deal with sockets. For now i'm concerned with responsiveness and scalability, and have been thinking of two ways to achieve that. The first way would be multiple calls to io_service.run, each in a different thread, using the strand object to synchronize the callback handlers. The other way is to explicit use threads and locks with the boost::thread lib. So could you point me what would be the … [View More]

ASIO iostreams example -- help?
by Dave Steffen 14 Jun '09

14 Jun '09

Hi Folks, I'm just getting into ASIO, and am having problems with the examples. I'm trying out both the tcp::iostream examples and the (more basic?) synchronous TCP daytime clients in the tutorial. I have the server print the socket endpoint, which produces: 0.0.0.0:23421 (23421 being a randomly typed socket number, once I figured out that the '13' in the examples doesn't work because Linux reserves socket numbers up to 1024 for the kernel). I then run the client, providing 0.0.0.0:23421 … [View More]

Simple question about boost::random
by Zachary Turner 13 Jun '09

13 Jun '09

I think I'm overlooking something very simple, but I'm trying to generate random numbers that are uniform over the open range of various data types. So I wrote this code: template<typename T> struct rand_type_range { typedef boost::numeric::bounds<T> bounds; static T generate() { static boost::uniform_int<T> range(bounds::lowest()+1, bounds::highest()-1); static boost::variate_generator<boost::minstd_rand&, boost::uniform_int<T> > generate(rng, range)… [View More]; return generate(); } }; Using this with anything other than a boost::uint32_t gives lots of warnings, although the results turn out correct. Looking at the warnings it seems the infrastructure is still trying to use boost::uint32_t's for everything, so am I missing something simple? 1>Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(135) : warning C4244: '+=' : conversion from 'unsigned long' to 'unsigned short', possible loss of data 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(64) : see reference to function template instantiation 'unsigned short boost::uniform_int<IntType>::generate<Engine>(Engine &,unsigned short,unsigned short,unsigned short)' being compiled 1> with 1> [ 1> IntType=boost::uint16_t, 1> Engine=boost::random::detail::pass_through_engine<boost::random::detail::pass_through_engine<boost::random::linear_congruential<boost::int32_t,48271,0,2147483647,399268537> >> 1> ] 1> Q:\include\boost\1.39.0\boost/random/variate_generator.hpp(100) : see reference to function template instantiation 'unsigned short boost::uniform_int<IntType>::operator ()<boost::random::detail::pass_through_engine<UniformRandomNumberGenerator>>(Engine &)' being compiled 1> with 1> [ 1> IntType=boost::uint16_t, 1> UniformRandomNumberGenerator=boost::random::detail::pass_through_engine<boost::random::linear_congruential<boost::int32_t,48271,0,2147483647,399268537> >, 1> Engine=boost::random::detail::pass_through_engine<boost::random::detail::pass_through_engine<boost::random::linear_congruential<boost::int32_t,48271,0,2147483647,399268537> >> 1> ] 1> Q:\include\boost\1.39.0\boost/random/variate_generator.hpp(100) : while compiling class template member function 'unsigned short boost::variate_generator<Engine,Distribution>::operator ()(void)' 1> with 1> [ 1> Engine=boost::minstd_rand &, 1> Distribution=boost::uniform_int<boost::uint16_t> 1> ] 1> c:\dev\agent\windows\tests\bit_search.hpp(54) : see reference to class template instantiation 'boost::variate_generator<Engine,Distribution>' being compiled 1> with 1> [ 1> Engine=boost::minstd_rand &, 1> Distribution=boost::uniform_int<boost::uint16_t> 1> ] 1> c:\dev\agent\windows\tests\bit_search.hpp(52) : while compiling class template member function 'boost::uint16_t rand_type_value<T>::generate(void)' 1> with 1> [ 1> T=boost::uint16_t 1> ] 1> c:\dev\agent\windows\tests\bit_search.hpp(62) : see reference to class template instantiation 'rand_type_value<T>' being compiled 1> with 1> [ 1> T=boost::uint16_t 1> ] 1>Q:\include\boost\1.39.0\boost/random/detail/signed_unsigned_tools.hpp(64) : warning C4244: 'return' : conversion from 'base_unsigned' to 'unsigned short', possible loss of data 1> Q:\include\boost\1.39.0\boost/random/detail/signed_unsigned_tools.hpp(64) : while compiling class template member function 'unsigned short boost::random::detail::add<T1,T2>::operator ()(T1,T2)' 1> with 1> [ 1> T1=base_unsigned, 1> T2=unsigned short 1> ] 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(116) : see reference to class template instantiation 'boost::random::detail::add<T1,T2>' being compiled 1> with 1> [ 1> T1=base_unsigned, 1> T2=unsigned short 1> ] 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(64) : see reference to function template instantiation 'unsigned short boost::uniform_int<IntType>::generate<Engine>(Engine &,unsigned short,unsigned short,unsigned short)' being compiled 1> with 1> [ 1> IntType=boost::uint16_t, 1> Engine=boost::random::detail::pass_through_engine<boost::random::detail::pass_through_engine<boost::random::linear_congruential<boost::int32_t,48271,0,2147483647,399268537> >> 1> ] 1>Q:\include\boost\1.39.0\boost/random/uniform_smallint.hpp(79) : warning C4244: 'return' : conversion from 'long' to 'unsigned short', possible loss of data 1> Q:\include\boost\1.39.0\boost/random/uniform_int.hpp(150) : see reference to function template instantiation 'unsigned short boost::uniform_smallint<IntType>::operator ()<Engine>(Engine &)' being compiled 1> with 1> [ 1> IntType=unsigned short, 1> Engine=boost::random::detail::pass_through_engine<boost::random::detail::pass_through_engine<boost::random::linear_congruential<boost::int32_t,48271,0,2147483647,399268537> >> 1> ] 1>Linking... 1>LINK : c:\dev\agent\windows\tests\debug-winxp\Win32\bin\tests.exe not found or not built by the last incremental link; performing full link [View Less]

unique_ptr?
by Robert Dailey 13 Jun '09

Hey guys, I remember a while back using boost::unique_ptr<Foo>, but I can't seem to find that class anymore. I'm using Boost 1.39. I noticed boost::interprocess::unique_ptr, but this isn't the same thing I'm looking for. Where can I find the boost::unique_ptr class? Is this in the sandbox somewhere? Thanks.

[PropertyTree] Rewrite - Please Review
by Sebastian Redl 13 Jun '09

13 Jun '09

Hi PropertyTree users, I have completed the main bulk of the property tree rewrite/cleanup. In the course of this, I have made the code standard-compliant (it previously used a std::list of an incomplete type, which is not, strictly speaking, valid), made it follow the claimed complexities (find() was O(n), although the docs said it's O(log n)), and revised the customization interface quite thoroughly. Inevitably, there were breaking changes in this process. I would ask everyone who has … [View More]existing code using PropertyTree to look at these changes and tell me their best guess at how much effort it would be to update the code to conform with the new interface, and how I could make this easier. The development is still in a branch, so you need to check out the SVN branch http://svn.boost.org/svn/boost/branches/sredl_2009_05_proptree_update to try out the new version. The breaking changes are as follows: 1) Probably the most common change need: ptree::find() now returns the new type assoc_iterator (const_assoc_iterator for the const version) instead of iterator (const_iterator). This means that you need to change the type of the variable you capture the result with to assoc_iterator. It also means you need to compare the result of find() against ptree::not_found() instead of ptree::end(). You can get an iterator from an assoc_iterator by passing it to ptree::to_iterator(). The other projection direction is currently not supported, although it would be trivial to add. 2) The number and order of template arguments to basic_ptree has been changed. The old arguments were * Key comparison predicate * Key type * Path type * Data type * Translator type The new arguments are * Key type * Data type * Key comparison predicate (defaults to std::less<Key>) The old order prevented defaulting and wasn't very useful in general. The new order is consistent with std::map. The path and translator arguments have been removed to simplify the interface of basic_ptree. Equivalent functionality is available (see below). If you used your own instantiation of basic_ptree before, instead of simply using the (wi)ptree typedefs, you will have to adapt your code to the new order. If you used custom path and/or translator types, read on. 3) put and put_child previously had a final parameter 'bool do_not_replace'. I don't like boolean parameters, especially those whose name contains a negation. I removed the parameter, and replaced its functionality by a pair of new functions, add and add_child. If you previously called put or put_child passing true for do_not_replace, you must change these calls to add or add_child, respectively. If you ever passed false explicitly, you have to remove this parameter. 4) Using custom path types has changed. You can no longer create individual basic_ptree instantiations with custom path types. Instead, a key type has a fixed path type associated with it. I can bring this functionality back pretty easily if required, but I want to see use cases for this first. (Such things are why I make this call for reviews.) Less template parameters to ptree is good, in my opinion. To use a key type other than std::basic_string specializations, you have to specialize boost::property_tree::path_of for this key type. The path_of struct contains a single type called type, which is the path to use for this key type. The way paths are implemented has also changed thoroughly. Previously, you had to implement a const and a non-const variant of get_child, plus put_child (with do_not_replace making that effectively two functions too). These functions contained a lot of logic that really belonged into ptree, making implementing custom paths tedious and error-prone. The new interface requires you to implement four functions, but they're far simpler. The functions are described in ptree_fwd.hpp in C++0x concept syntax, but here's the gist: bool path::empty() const -> is the path empty? bool path::single() const -> does the path contain a single element? key_type path::reduce() -> chop off the first part of this path and return it (basically a pop_front that returns the value). std::string dump() const -> get a readable form of this path for exception messages; feel free to return "" here if you don't care. The new interface should be easy to implement, and the tree traversal is now where it belongs (in the internal implementation functions walk_path and force_path). 5) Using custom translators has changed. A ptree no longer has a fixed translator associated with it. Instead, you can supply a custom translator to every get_value/get/put_value/put operation or use the default, which depends on the tree's data type and the type you extract/insert. An example: ptree pt; pt.put("k1.k2", 100); // Uses the default translator for std::string+int. // Note: the explicit template parameter here will go away. float f = pt.get<float>("k1.k2", my_special_float_string_converter()); The tree's own data type is called the internal type, while the parameter/return type is called the external type. The default translator for a internal+external pair is set by specializing the boost::property_tree::translator_between struct. By default, PropertyTree supplies an id_translator for when the internal and external types are the same, and a stream_translator for converting between a basic_string and anything else. Together, they faithfully emulate the behavior of the old default translator. Writing a custom translator is easy. It's a class that provides two typedefs and two functions: typename internal_type -> the internal data type typename external_type -> the external data type optional<external_type> Tr::get_value(internal_type) -> convert from the internal to the external type, boost::none on failure optional<internal_type> Tr::put_value(external_type) -> convert from the external to the internal type, boost::none on failure That's it for the changes. The new version of property tree is not quite complete yet. I still need to polish the documentation a little and document the new extension mechanisms properly. I also need to clean up a little. Finally, the INI parser doesn't work at the moment. However, the main functionality (tested by property_tree_test) plus the XML, JSON and INFO parsers should all work now. Looking forward to your feedback. Sebastian [View Less]

[program_options] [msvc 2010] 1.34.1: Error when compiling
by Boris Dušek 13 Jun '09

13 Jun '09

Hello, I got hands on the Visual Studio 2010 Beta 1 and had to rebuild the 1.34.1 version of boost libraries I use in my project with the new VC 10 compiler. Thread, Test, IOStreams, Filesystem built fine, but program_options failed. Let me first clarify why I do need 1.34.1: This is the version that is most available on Linux servers (including the one I develop for), so I need this version on my development box to ensure source code compatibility, even though this version does not officially … [View More]support even VC 9 (which however builds it fine and I happily use it). Below I list the errors that happened with the VC 10 compiler. I aggregated them to 3 issues. For multiple occurences of issue 1., I only copy/paste the full output for the first occurence. I would welcome if someone could tell me if these are the new compiler's fault, or not. If they are, I plan to report them on MS Connect so that they can hopefully get fixed before next Beta (or at least before the RTM). 1.

Serializing derived class in dll

[mpi] failed test and other issues
by Nick Collier 12 Jun '09

12 Jun '09

Hi, I'm using boost-1.39.0 with openMpi 1.3.2 on OSX 10.5.7. I'm getting some strange behavior when sending and receiving a vector of pointers between processes. The received pointer addresses are sometimes invalid. I'm not using the skeleton content code, just sending and receiving the vector. Some output: [2] processing edges from 1 [2] unpacking edge 0x834810 [2] unpacking edge 0x834810 [0] processing edges from 2 [0] unpacking edge 0x834ec0 [0] unpacking edge 0x834ec0 [2] … [View More]processing edges from 3 [2] unpacking edge 0x8346c0 [2] unpacking edge 0x8346c0 [2] processing edges from 0 [2] unpacking edge 0x1 [2] unpacking edge 0x1 The hex value is the pointer address, and obviously doing anything with the edge with the weird address causes the app to crash. I can't see that I'm doing anything wrong (although of course that's a possibility) and so I thought I'd run the boost mpi tests. The skeleton_content_test fails consistently with the following output: Broadcasting integer list skeleton from root 0...OK. Broadcasting integer list content from root 0...OK.

[Multi-Index] Get container view of a non-unique-index equal_range?
by Dominique Devienne 12 Jun '09

Given for example class Ident : public noncopyable { .. .}; class VehicleIdent : public Ident { ... }; struct ByUid {}; struct ByType {}; struct ByNKey {}; struct VehicleIdentHash { ... }; struct VehicleIdentPred { ... }; typedef boost::multi_index_container< shared_ptr<VehicleIdent>, indexed_by< hashed_unique< // primary (surrogate) key tag<ByUid>, BOOST_MULTI_INDEX_CONST_MEM_FUN( Ident, const Uid&, uid … [View More] ) >, hashed_unique< // natural key (logical primary key) tag<ByNKey>, identity< shared_ptr<VehicleIdent> >, VehicleIdentHash, VehicleIdentPred >, // additional index to iterate on a type range (e.g. all Cars) hashed_non_unique< tag<ByType>, BOOST_MULTI_INDEX_CONST_MEM_FUN( VehicleIdent, const string&, type ) > > > VehicleIndex; typedef VehicleIndex::index<ByUid>::type VehicleByUid; typedef VehicleIndex::index<ByType>::type VehicleByType; typedef VehicleIndex::index<ByNKey>::type VehicleByNKey; I'd like to be able to have a "view" of VehicleIndex, for example compatible with unordered_set in this case since using a hashed index, for a given vehicle type ("Audi" for example), and going further have this view allow inserts which would go into the "master" vehicle index under the cover, validated by its unique indexes. In pseudo-code, something a bit like this: struct VehicleMake { VehicleByType::EqualRangeView& models_; VehicleMake(const string& name) : models_(get<ByType>(get_vehicle_index()).equal_range_view(name)) {} }; With models_ behaving has a normal container one can iterate on (begin, end), query (empty, find, count), modify (insert, erase, clear, etc...), those operations only affecting the VehicleIndex elements matching the VehicleByType given range, and possibly asserting all inserts are valid for the range (the vehicles added via the "range view" have the type matching the range's type). Can this be done? Has it been considered as a possible extension, and is it even feasible given the current B.MI design? Any input on how to achieve or emulate the above would be appreciated. Thanks, --DD PS: The above design is synthetic of course. We have a parent-child hierarchy of C++ objects where parents have lists of their children, but now there's a list of all children, from all parents, in a B.MI, indexed (non-unique) on the parent instance, and I'd like the "concrete" list maintained by each parent to become the kind of "view" I'm describing above. Right now I'm manually maintaining the sync of the existing and the new "master" list (the B.MI index), having to "sprinkle" the code to keep them in sync, but the "view" approach above would be cleaner IMHO, and avoid many potential bugs from forgetting to "sprinkle" in all the right places.

I am interested in your recommendation of any open source, cross-platform C++ libraries designed for programming the major databases (Oracle, MySql, Postgres, MS Access, Sybase, etc). Boost does not provide any such database/sql library framework for C++. If you can point me toward a source or sources that do offer such a framework, and possibly one(s) the Boost people favor, it would be very much appreciated. Primarily, I am developing code for Windows and Unix/Linux.

shared_ptr binary compatibility

Are shared_ptr binary compatible through boost versions? Example: Imagine a "Producer" class that sends shared_ptr to a "Consumer" class. Now imagine an executable that instanciate a Producer and a shared library (.dll or .so) that instanciate a Consumer. The executable is built with boost v1.xx. The shared library is built with boost v1.yy. If xx == yy, obviously there will be no problem since the version of the shared_ptr is the same. However if xx != yy, there might be a problem since … [View More]

Hi, I'm using an event loop type system which I've implemented myself. This is due to specific needs. Event loop is fairly simple, it has several types of events: - Timer based events (relative or exact, repeating, etc) - IO based events - Notification based events Notifications are events which can come from any thread, and get processed on in the main loop. Here is the function which is used to post a notification. REF(t) is simply a macro for boost::intrusive_ptr<t>. … [View More]

Problem with throwing exceptions in async handler functions of ASIO library
by J.W.F. Thirion 11 Jun '09

11 Jun '09

Dear Boost community, We're having a problem using the ASIO class with multiple IO service threads and throwing exceptions inside the handle_xxx functions, as used by the async_xxx functions of the ASIO library. It seems that when any error is thrown in a normal/non-handler function, the try/catch block of the main program is able to catch the error. However, when the handler functions are called (I would assume by the io service, now running in a separate thread), the main function's try/… [View More]catch blocks never receive the execeptions, and a std::terminate() is called automatically. To demonstrate this, we've taken the HTTP Server 2 example from the ASIO examples page and reduced its complexity. Below are the sources of the example. Basically, to duplicate the problem, run the main executable and then in another terminal, simply "telnet 127.0.0.1 60000" to see the std::terminate() being called, even though there are try/catch blocks in the main function (main.cpp). Here is an output: $ ./main terminate called after throwing an instance of 'int' Aborted $ We've also taken the HTTP Server 2 example "as is" and added a "throw 123;" at the top of handle_accept in server.cpp and a "catch (...)" block in posix_main.cpp. The same issue occurred here, which indicates that the exceptions are not propagated through all the way (maybe because the io service runs in a separate thread). Does anyone have a suggestion on how we can throw exceptions inside the handler functions of the async functions used? We'd like to handle all our errors with custom exception classes (e.g. ExceptionAccept is thrown if there is an error detected in handle_accept, which can then be handled inside the main function of main.cpp). We've compiled the sources below by typing: g++ -I/usr/local/boost/include/boost-1_38 -L/usr/local/boost/lib -lboost_thread-gcc41-mt-1_38 -lboost_system-gcc41-mt-1_38 io_service_pool.cpp server.cpp main.cpp -o main where /usr/local/boost is the local boost installation path.

boost::test test case levels

Hi there! Our automatic tests are of two kinds: short (just like BOOST_CHECK_EQUAL(2*2, 4);), and complicated, which process bulks of random data (for instance, to check if a map with random numbers is always sorted). So we’d like to select which test cases to run: either simple ones or all. I see two ways: 1. Default variants release, debug build and run only simple test cases. We define another feature (or even a build variant) that builds and runs all the tests. This will require … [View More]

[Boost.Thread] Join not waiting?
by James Auger 11 Jun '09

11 Jun '09

This is my first time working with Boost.Thread and I'm having some difficulty in that Join does not seem to work (obviously I'm doing something wrong). In a nutshell what I'm doing is: Instantiating the Example class (which has a boost::thread as a member variable) calling Example::run() (which starts the thread) do some stuff (both in main and in the thread) calling Example::terminate() (which sets the condition for the thread function to stop, and calls Join) end. The problem … [View More]is that Join returns instantly, before the thread has finished. In the code below I've commented out the stop condition (making the thread run an infinite loop) to demonstrate that it keeps running after join returns. By my understanding of how boost threads and join works, this is not the correct behavior; my understanding is that the call to join should not return until the thread has stopped running. Either my understanding is wrong, or my code to make that happen is wrong. Can you guys help me? The example is stripped down/simplified code that I wrote to demonstrate and test what was going on in my actual program. Example Output: --- thread: main: 00 thread: main: 11 thread: main: 22 thread: main: 33 main: thread: 44 main: After Terminate thread: 5 thread: 6 thread: 7 thread: 8 --- Note the interleaved output 0 - 4, that's expected and fine. The problem is the thread is still running (as evidenced by writing to cout) after terminate() (and thus join()) has been called on that thread. Example Code: --- #include <iostream> #include <boost/thread/thread.hpp> #include <boost/thread/mutex.hpp> #include <boost/bind.hpp> class Example { public: Example() { flag = 0; }; void run() { flag = 1; boost::thread _myThread(boost::bind(&Example::threadLoop, this)); }; void terminate() { //flag = 3; //commented out stop condition _myThread.join(); }; private: void threadLoop() { flag = 2; for(int i = 0; flag == 2; i++) { boost::this_thread::sleep(boost::posix_time::seconds(1)); std::cout<<"thread: "<<i<<std::endl; } flag = 4; }; boost::thread _myThread; int flag; }; int main() { Example anExample; anExample.run(); for(int i = 0; i < 5; i++) { boost::this_thread::sleep(boost::posix_time::seconds(1)); std::cout<<"main: "<<i<<std::endl; } anExample.terminate(); std::cout<<"main: After Terminate"<<std::endl; boost::this_thread::sleep(boost::posix_time::seconds(5)); //sleep so we can see the thread still outputing return 0; } --- Thanks!

Re: [Boost-users] [Boost.CircularBuffer] begin()/end() arithmetic not working out quite right
by Jan Gaspar 11 Jun '09

11 Jun '09

Hi David, you just cannot rely on this. I don't think standard says anything about begin() moving forward after push_back(). Correct me if I'm wrong. The way how it is implemented is that if the circular_buffer is empty begin() returns the same iterator as end(). There is also a note about iterator invalidation for push_back(): "Does not invalidate any iterators with the exception of iterators pointing to the overwritten element." It means iterator 'a' in your first example will point to … [View More]the same element as it was before calling push_back() - which is end(). This explains the behaviour you are describing.

This is very useful since many of my applications require it. I am having a problem though... I am using Boost 1.38.0. When I call push_back(), the iterator math makes it appear that begin() moves backwards and end() remains constant. (Based on other STL libraries, I expect that begin() will remain constant and end() will keep advancing as I call push_back()). In other words, this assertion fails (but I expect it to succeed): circular_buffer<int> buf(8); circular_buffer<int>::iterator a; circular_buffer<int>::iterator b; a = buf.begin(); buf.push_back(1); b = buf.begin(); assert(a == b); // Fails!! Also, this code fails too (but I expect it to succeed): circular_buffer<int> buf(8); circular_buffer<int>::iterator a; circular_buffer<int>::iterator b; a = buf.end(); buf.push_back(1); b = buf.end(); assert(a != b); // Also fails! Below is a full example that you can compile and try out: #include <boost/circular_buffer.hpp> #include <stdio.h> int main () { typedef boost::circular_buffer<int> buf_type; // Instead of "end" moving ahead, "begin" is moving backwards when // // using "push_back". { buf_type buf1(1024); buf_type::iterator a; buf_type::iterator b; a = buf1.end(); buf1.push_back(1); buf1.push_back(2); b = buf1.end(); printf ("%d\n", a == b); // >>> // got: 1 // expected: 0 printf ("%d, %d\n", a-buf1.begin(), b-buf1.begin()); // >>> // got: 2, 2 // expected: 0, 2 } { buf_type buf2(1024); buf_type::iterator c; buf_type::iterator d; c = buf2.begin(); buf2.push_back(1); buf2.push_back(2); d = buf2.begin(); printf ("%d\n", c == d); // >>> // got: 0 // expected: 1 // (i.e. "begin()" is not still pointing to first item!! // This is incorrect, isn't it?) printf ("%d, %d\n", buf2.end()-c, buf2.end()-d); // >>> // got: 0, 2 // expected: 2, 2 } return 0; } Thanks, David [View Less]

When I call push_back(), the iterator math makes it appear that begin() moves backwards and end() remains constant. (Based on other STL libraries, I expect that begin() will remain constant and end() will keep advancing as I call push_back()). In other words, this assertion fails (but I expect it to succeed): … [View More]

boost::multi_array SWIG binding
by NJ Duncan 10 Jun '09

10 Jun '09

Hi all, I'm fairly new to C++ and learning as I go, but there is very little info out there on my particular problem. I am trying to turn a model I've written in C++ into a python module using SWIG. The main problems I'm having are initializing Boost multiarray containers then getting data into and out of them. Here is some sample code: #include <iostream> #include <vector> #include <algorithm> #include "boost/multi_array.hpp" typedef boost::multi_array<double,2> … [View More]array_typef; typedef boost::multi_array<int,2> array_typei; class G2G_hydro_model { public: array_typei A; array_typef S; G2G_hydro_model(int A_ncols,int A_nrows,int S_ncols,int S_nrows):, A(boost::extents[A_ncols][A_nrows]), S(boost::extents[S_ncols][S_nrows]) {}; ~G2G_hydro_model(void) {}; void read_floating(int x, int y, array_typef& data, double& element); void write_floating(int x, int y, array_typef& data, double& element); void write_integer(int x, int y, array_typei& data, int& element); void functions_to_do_stuff(array_typef&,array_typei&) }; void G2G_hydro_model::read_floating(int x, int y, array_typef data, double element) {element = data[x][y];} void G2G_hydro_model::write_floating(int x, int y, double element, array_typef data) {data[x][y] = element;} void G2G_hydro_model::write_integer(int x, int y, int element, array_typei data) {data[x][y] = element;} Code is pushed through SWIG to create bindings, then compiled as a linked library. Compiles ok with no warnings and Python accepts the module. But when I try to use with Python code like this: import sys import numpy as np import G2G h = G2G4.G2G_hydro_model(A.cols,A.nrows,S.cols,S.rows) element = 9 for x in range(0,A.cols) for y in range(0,A.rows) h.write_integer(x, y, element, h.A) Unfortunately I get the following error message: python: /usr/include/boost/multi_array/multi_array_ref.hpp:481: boost::multi_array_ref<T, NumDims>& boost::multi_array_ref<T, NumDims>::operator=(const ConstMultiArray&) [with ConstMultiArray = boost::multi_array<double, 2ul, std::allocator<double> >, T = double, long unsigned int NumDims = 2ul]: Assertion `std::equal(other.shape(), other.shape()+this->num_dimensions(), this->shape())' failed. I think I have assigned the array extents incorrectly, but I'm not sure of the proper way to do this as part of a C++ class. Any ideas, I'm starting to pull my hair out, I hope there is a simple answer.

[Boost.Graph]: read_graphviz into std::vector

Hi, I have graphes in the .dot format, with 24 vertex labels d1-d24, each storing one double. I want to use struct Vertex_p { std::string node_id; std::vector<double> d; } as the bundled property for my graph in boost and use read_graphviz to load the graph.

Obtaining base class type
by Robert Dailey 09 Jun '09

Hey everyone, I'm using wxWidgets, and as you all may know they have a silly macro used to define an event table... BEGIN_EVENT_TABLE( MainWindow, wxFrame ) EVT_CLOSE( MainWindow::OnClose ) END_EVENT_TABLE() I spend a few hours finding out that wxFrame is the incorrect parameter for parameter #2. This is not the base class that MainWindow derives from. There was no compiler error or warning, nor any errors during runtime. Only weird behavior because events were getting skipped.

assignment operator could not be generated
by Zachary Turner 09 Jun '09

09 Jun '09

When building a project that uses boost on Windows under MSVC 9.0 (VS 2008), I get _tons_ of warnings for "assignment operator could not be generated" all throughout the code. Is this going to cause subtle errors when I run the code, or are the warnings harmless ones that can be disabled with pragmas? One example where I get lots of "assignment operator could not be generated" spam is in boost::detail::addr_impl_ref<T> when I try to use boost::bind.

[Boost.Test] BOOST_FAIL vs BOOST_ERROR
by Greg Christopher 09 Jun '09

09 Jun '09

Hi, I'm new to Boost testing and I am looking to distinguish whether boost.test has a certain facility. It is clear from the documentation that BOOST_FAIL reports a problem and then quits, whereas BOOST_ERROR reports a problem then continues. My chief concern right now is how problems are reported actually- not control flow. I am wondering if boost.test has a facility to signal that something is wrong with the testware itself (not the software under test) . For instance, a reporting … [View More]

Expand tuple values as callable arguments
by Dominique Devienne 09 Jun '09

09 Jun '09

Given a boost::tuple<A,B,C> abc; is there a boost facility that allows to "expand" abc into its a, b, c values to pass to a callable (actual function T f(A,B,C), boost::function<T(A,B,C)>, fusion callables, etc...)? If so, would implicit conversions allowed and performed during a real call also happen using that facility? And if the "callable" is a constructor, is there a way to call a constructor? Thanks, --DD PS: Our app is plugin based and heavily uses factories in the base … [View More]

[Bind] Placeholder scope
by Robert Jones 09 Jun '09

09 Jun '09

I have just spent several hours digging out a compile problem which turned out to be a conflict between Boost.Bind and Boost.Lambda, which seems to arise because the Boost.Bind placeholders (_1, etc.) are in the global namespace, so if "using namespace boost::lambda;" is in effect the Bind placeholder is used rather than the Lambda placeholder. I wonder why the Bind placeholders are in the global namespace? Thanks, Rob.

Access function parameter types as mpl sequence?
by Dave Bonora 09 Jun '09

09 Jun '09

Does boost contain a utility that can generate an mpl sequence populated with the parameter types of a given function? I'm hoping to avoid the pains of implementing the functionality myself. For instance, given the function: void Func( int, const char* ); I could generate and access an mpl::vector sequence: mpl::vector<int, const char*> Thanks!

shared_ptr and && operator
by Robert Dailey 09 Jun '09

09 Jun '09

Hey guys, Just wondering what happens if I do this: boost::shared_ptr<Foo> foo; boost::shared_ptr<Bar> bar; if( foo && bar ) { // Do stuff if both pointers are valid... } I did not see an overloaded && operator in the interface of the class. When using normal pointer semantics, this code is valid through implicit conversion of a pointer value to a boolean type.

[BGL] What is filtered_graph really doing?
by Lindley M French 08 Jun '09

08 Jun '09

My edge properties struct has a bool "on" member. At times I may want to change whether an edge is on or not, and then I want to generate filtered_graphs that contain only the on or off edges for use with BGL algorithms. However, it doesn't seem to be working. If I do: func(Graph &G) { filtered_graph<Graph> F1(G,OnEdges(G)); // iterate over the edges of F1 and print them out // Now iterate over the edges of G and turn some of them off, printing out which ones … [View More]

[Serialization] Stack Overflow on exit in 1.39.0: patch possibly available?
by Enrico Carrara 08 Jun '09

08 Jun '09

Hello, As others did (see http://lists.boost.org/boost-users/2009/05/48047.php) I had the problem of stack overflow on program exit while using BOOST_CLASS_EXPORT with version 1.39.0, probably due to an error in void_caster.cpp. Is it possible to have a patch for it before delivery of next version and how? Thanks in advance, eca

string_algo and vector
by gast128 08 Jun '09

08 Jun '09

Dear all, the documetnation was alittle bit vague about the use of other sequences with string_algo. However I would expect that a vector and a string have many similarities, but still I got a crash when using a vector (with Visual Studio 2003, Boost 1.36): void Foo() { //crashes with vector: std::vector<int> v1 = boost::assign::list_of(1)(3)(5)(7)(9); std::vector<int> v2 = boost::assign::list_of(3)(5); boost::algorithm::erase_range(v1, v2); _ASSERT(v1.size(… [View More]
