Could you explains the reasons? I see 2 problems with this approach: 1. creation of ptime object on stack, why? 2. Base class already has those operators, so why do you hide them? > Jeff > _______________________________________________ Thanks Roman Yakovenko

I posted the error here, because I think that this error indicates, that something wrong with design. I think that date_time library should define local_microsec_clock, not in terms of microsec_clock, but using an other class that is aware of time zone. Why is microsec_clock class not aware of time zones? > Jeff Thanks Roman Yakovenko

date_time: special_value_from_string link error
by Roman Yakovenko 28 Nov '05

28 Nov '05

Hi. Free function special_value_from_string is missing BOOST_DATE_TIME_DECL. This cause link error on windows, vc 7.1, while working with date time library as dll. ( boost version is 1.33.1 beta ) Thanks Roman Yakovenko

date_time: second_clock and microsec_clock errors
by Roman Yakovenko 28 Nov '05

28 Nov '05

Good morning. I think I found small bug, but I am not sure. ( boost version is 1.33.1 beta ) Description: [micro]second_clock< boost::local_time::local_date_time_base<> > could not be compiled. The problematic function is: private: static time_type create_time(::std::tm* current); The error is that local_date_time_base<> does not have constructors that takes date and time duration. Thanks Roman Yakovenko

date_time: local_date_time small fix
by Roman Yakovenko 28 Nov '05

28 Nov '05

Good morning. Consider next use case: struct my_ldt : public boost::local_time::local_date_time_base<>{ my_ldt() : boost::local_time::local_date_time_base<>( boost::posix_time::ptime() , boost::shared_ptr< boost::date_time::time_zone_base<boost::posix_time::ptime> >() ) {} }; int _tmain(int argc, _TCHAR* argv[]) { boost::posix_time::ptime t; my_ldt m; m == t; //^^^^^^^^ //this will not compile ( at least on VC 7.1 ) //the error is error C2678: binary '==' : no operator found which takes a left-hand operand of type 'my_ldt' (or there is no acceptable conversion) } fix: Add next code to the local_date_time_base class typedef date_time::base_time<utc_time_, boost::posix_time::posix_time_system> base_type; using base_type::operator==; using base_type::operator<; using base_type::operator-; Thanks Roman Yakovenko

Is the boost::factory mentioned in this thread available in the new vault anywhere? Is it possible for anyone to upload it? *http://lists.boost.org/boost-users/2005/05/11828.php*<http://lists.boost.org/boost-users/2005/05/11828.php> Thanks, Dave

Boost.Iostreams - memory leak in zlib filter
by Martin Slater 28 Nov '05

28 Nov '05

Hi there, Just been tracking a memory leak that ended up coming out of the zlib filter. We're using the boost 1.32.0 with the last non integrated verison of iostreams from Jonathans website, I've integrated what appear to be fixes for this leak in the current cvs head but the leak was still there. It seems that line 383 in boost\iostreams\filter\zlib.hpp (cvs head version) should be void zlib_decompressor_impl<Alloc>::close() { reset(false, false); } instead of void zlib_decompressor_impl<Alloc>::close() { reset(false, true); } This makes the leak go away for me, does this seem right? cheers Martin

[1.33.1][test] missing include problem
by Graham Bennett 28 Nov '05

28 Nov '05

Hi all, When compiling the 1.33.1 beta I noticed that a missing #include is causing a compilation problem: boost/test/impl/plain_report_formatter.ipp is missing a #include <ostream>. I'm using the Roguewave standard library, which often turns this kind of error up as its standard headers don't include quite the same set of files as gcc. It would be great if this could be fixed for the final release of 1.33.1. cheers, Graham -- Graham Bennett
