number ranges and compile-time errors
by Reece Dunn 10 May '04

10 May '04

Is there a boost library that allows you to specify the range that a number can take, e.g. boost::range< int, 1, 12 > month; generating an error on an invalid range, e.g. month = 20; // [1] oops! Also, is it possible to distinguish between a number literal like the above and a variable assignment, like: month = m; // [2] The logic behind this is to provide compile-time checks where possible, so [1] would produce a compile-time error and [2] would be a run-time error. You could also do something like: inline char & string::operator[]( boost::range< int, 5, 10 > i ){ ... } // ... string s; s[ 1 ] = 'a'; // oops! and class date { boost::range< int, 1, 12 > month; public: inline date( boost::range< int, 1, 12 > m ): month( m ){} }; Regards, Reece _________________________________________________________________ Sign-up for a FREE BT Broadband connection today! http://www.msn.co.uk/specials/btbroadband

Large files ( > 2GB) and boost::filesystem library
by David Judson 10 May '04

10 May '04

In a number of places in the filesystem library on Linux, the ::stat file system call is used. When this call is executed on a file whose size is larger than 2GB, it fails because the file size cannot fit into the default "stat" structure. This problem happens even when the size information in the stat structure is not used. For example the stat information is used in the directory iterator to look for sub directories. This can be corrected by setting the macro _FILE_OFFSET_BITS to 64. What is the best way to set this macro on Linux? I have looked at the jam rules and cannot locate the appropriate place to include the definition. Also, what process should be followed if I want to have this macro defined either by default or at least as an option in the boost source tree so that I don't have to modify the build rules each time I install boost?

Did someone just import an archive to the boost gmane group? I've been getting old (1998+) postings and no new ones all day, also they are not in order which is kind of annoying.. -- Daniel Wallin

borland workaround still needed
by Gennadiy Rozental 10 May '04

Hi, I an trying to make protected member defined in base class public: template<class PropertyType> class class_property { protected: PropertyType value; }; template<class PropertyType> class readwrite_property : public class_property<PropertyType> { public: typedef class_property<PropertyType> base; #if BOOST_WORKAROUND(__BORLANDC__, <= 0x570) base::value; #else using base::value; #endif }; Borland fail to compile it, stating something about an attempt to grant access to protected member. Well that's the whole point!! Any suggestions? Gennadiy.

patch: boost/math/special_functions => compile error in asinh.hpp, acosh.hpp and atanh.hpp
by Huber, Carsten 10 May '04

10 May '04

Hello boost developers, this is my first mail to boost(a)lists.boost.org and it is already a bug that I found in the latest release 1.31.0 :-( I tried to compile boost::math::asinh, boost::math::acosh and boost::math::atanh recently and got a compile error "C2039 'abs' : is not a member of '_STL'" on my MSVC6 compiler. I have STLPort 4.5.3 installed and thought, this might be the problem, but then I found out that boost::math::sinc_pi and boost::math::sinhc_pi compile with no errors. To make it short: asinh, acosh and atanh are using ::std::abs, ::std::sqrt and ::std::log - which are not part of the STL. To fix this problem, I have created a patch - see attached files.

Regression testing -- some new testing options?
by Jeff Garland 09 May '04

09 May '04

Robert Ramey & I have been having a discussion offline about the impact of new boost libraries on the time it takes to run the regression tests. Serialization has a particularly time consuming test -- the so called 'torture test' suite. The problem is, that once serialization is in the tree it will be important to run that full test from time to time (like right before release), but it would probably be overkill to run everyday. And from past dicussion it is clear that running the regression test is already becoming very time consuming. Of course this isn't a serialization specific issue. With more and more libraries added the time to do any sort of regression test is continuing to grow. In addition, there is now the 'dll' versus 'static' library dimension for those of us with compiled libraries. It might be nice to sometimes run one or the other to speed things up. Also, Robert would like to be able to run 'debug' versus 'release' tests from time to time. So here's a suggestion. Perhaps it be possible to create a standard way we could set up the regression test targets so that library authors could: 1) define a couple standard test levels - say 'basic' and 'torture' 2) DLL versus static tests would be an option on the regression suite -- so you could run only one or both. Of course this isn't an issue for header libraries. 3) debug versus release is an option 4) define specific compiler/platform exclusions I believe such a design could increase the regression test effectiveness by allowing some contributors and users to run only one set of options (eg: 'basic-dll-release') tests. This option would be much-much faster than 'torture-all-all' -- which for a compiled library needs to compile and excute 4 versions of the tests (dll-release, dll-debug, static-release, static-debug). The compiler/platform exclusions would save time by just skipping over stuff that is going to fail and will never be fixed. There may be some way of doing this now, but ideally we would have some way of specifying this in the bjam file for the tests. Thoughts? Jeff

Obviously, I failed to capture the problem in the snippet, the actual error that's troubling me can be consulted at: http://tinyurl.com/ysmxq The diagnostic seems to be related with the fact that composite_key_result_less privately inherits from composite_key_compare while allowing public access to the base's operator() with a using declaration. Any idea about this? I'll be more than happy to provide further info to anyone who has a clue about the problem, or whishes to try the test in VC 7.1.
