Memory Leak with flat_map.insert(Iterator,Iterator)
by Adam Baxter 09 Sep '13

09 Sep '13

Hello, I'm experiencing a memory leak using the flat_map.insert(Iterator, Iterator) function. The leak goes away if I do regular for loop and use flat_map.insert(*Iterator). Is this a known issue? If not, what would be helpful for a bug report? Adam

Regex comparision
by Prakash Reddy Bande 09 Sep '13

09 Sep '13

Hi, I would like to change a regular expression in a compatible way. Here is the use case. Initially, in the configuration I defined a reg-exp for validation of data before persisting it. Some data was created and persisted, later the reg-exp required a change, however, the change must be done is such a way that existing data should not become invalid. Example: Initial validation says "no ; (semi-colon) and : (colon) in the text". However, later we decide to relax the constraint and want to … [View More]

[thread] Internal compiler error when trying to make movable future
by Gavin Lambert 09 Sep '13

09 Sep '13

Am I doing something wrong in the following code? #include <boost/thread/future.hpp> template<typename T> struct test_node { BOOST_THREAD_MOVABLE_ONLY(test_node) typedef boost::unique_future<test_node> future_node; T value; future_node next; }; (In the "real code" I've defined move constructors etc as well of course, but they don't affect the result so I've omitted them for brevity.) Using boost v1.53 with BOOST_THREAD_VERSION==2 and VS2008 (non C++… [View More]11 compiler), the above code produces an internal compiler error: 1>t:\boost\boost_1_53_0\boost\type_traits\is_convertible.hpp(484) : fatal error C1001: An internal error has occurred in the compiler. 1>(compiler file 'msc1.cpp', line 1411) 1> To work around this problem, try simplifying or changing the program near the locations listed above. 1>Please choose the Technical Support command on the Visual C++ 1> Help menu, or open the Technical Support help file for more information 1> t:\boost\boost_1_53_0\boost\thread\detail\is_convertible.hpp(22) : see reference to class template instantiation 'boost::is_convertible<From,To>' being compiled 1> with 1> [ 1> From=test_node<int> &, 1> To=boost::detail::thread_move_t<test_node<int>> 1> ] 1> t:\boost\boost_1_53_0\boost\mpl\if.hpp(63) : see reference to class template instantiation 'boost::thread_detail::is_convertible<T1,T2>' being compiled 1> with 1> [ 1> T1=test_node<int> &, 1> T2=boost::detail::thread_move_t<test_node<int>> 1> ] 1> t:\boost\boost_1_53_0\boost\thread\future.hpp(519) : see reference to class template instantiation 'boost::mpl::if_<T1,T2,T3>' being compiled 1> with 1> [ 1> T1=boost::thread_detail::is_convertible<test_node<int> &,boost::detail::thread_move_t<test_node<int>>>, 1> T2=boost::detail::thread_move_t<test_node<int>>, 1> T3=const test_node<int> & 1> ] 1> t:\boost\boost_1_53_0\boost\thread\future.hpp(1398) : see reference to class template instantiation 'boost::detail::future_traits<T>' being compiled 1> with 1> [ 1> T=test_node<int> 1> ] 1> s:\tests\nodetest.cpp(26) : see reference to class template instantiation 'boost::unique_future<R>' being compiled 1> with 1> [ 1> R=test_node<int> 1> ] 1> s:\tests\nodetest.cpp(56) : see reference to class template instantiation 'test_node<T>' being compiled 1> with 1> [ 1> T=int 1> ] The internal error goes away if I remove the MOVABLE_ONLY macro or the future_node instance field. The equivalent move code (using boost::detail::thread_move_t directly) for boost 1.47 compiles and works successfully (but crashes again if I switch to boost 1.53). Is this a regression in boost or am I doing something incorrect somewhere? Does anyone know of a workaround? Note that it does not matter if I try to use Boost.Move syntax instead, as unique_future<> internally uses Boost.Thread's move implementation, which is where things seem to be failing. One possible issue is that I'm trying to declare a future to an incomplete type (because it's self-referential), which is possibly confusing some of the internal checks it wants to do. But again, this usage used to work, and I'm not sure how to fix it given the new boost version. At least not without introducing pointers and heap allocation, which I really didn't want to do.

[accumulators] Help with accumulator-based typedef
by Michael Powell 09 Sep '13

09 Sep '13

Hello, I am trying to setup a "simple" weighted_mean accumulator for a struct I want to accumulate. It goes something like this. Let's call it a float for sake of example. It's actually a struct with mathematical comprehension: addable, subtractable, multipliable, dividable, and so on. typedef accumulator_set<float, stats<tag::rolling_mean>, features<tag::count, tag::weighted_mean> > my_float_accumulator_set; However, I am getting obscenely long errors complaining … [View More]

[accumulators] Moving mean expiry
by Michael Powell 08 Sep '13

08 Sep '13

Hello, I am looking for a moving window mean accumulator. Could roll my own, but I know there's a pretty good one in Boost. Need to know, does it comprehend the notion of Expiration? That is, values dropping off after a predetermined window of time? Preferably depending on the boost::chrono::high_resolution_clock. Thank ye... Regards, Michael Powell

[spirit] Qi-adapted-struct light bulb
by Michael Powell 07 Sep '13

07 Sep '13

Hello, A light bulb went on for me with regard to adapting structs into Qi parser grammars. Feel free to correct me if I'm wrong. The key is adapting a struct into your grammer's parser(s) using the BOOST_FUSION_ADAPT_STRUCT, which identifies the type (struct) and fields you are synthesizing out of the grammar. It doesn't mean that there can't be other (presumably) public variables, functions, etc, in the struct. It also doesn't mean there can't be private or protected or even a hierarchy of … [View More]

by Michael Powell 06 Sep '13

Hello, Need a little guidance when it comes to adapting structs. Let's say I've got a simple struct: struct data_t { int a; int b; int c; }; When I adapt it, I need to specify the fields into which the values are being consumed and subsequently synthesized? What happens for optional consumers, in one use-case? In another use-case, what happens if one value or another value or a third value can be consumed for that field? So, something like this, pardoning the pseudo-code: using qi:… [View More]
