This is marked with the ref note - "fails intermittently" - the failure is an result of the fact I haven't been able to make Jamfile run tests in a particular sequene. I could remove the markup - but that would leave several failures as expected when in fact I know what they are. Robert Ramey

lexical_cast to self
by Maxim Yegorushkin 03 Oct '04

03 Oct '04

In generic code lexical_cast<> is sometimes used as a cast to the same type. I would like to shortcut this rather then going all the way by writing it to a stream and reading back. In my code I use the following workaround: template<class U, class T> inline typename boost::disable_if<boost::is_same<T, U>, U>::type lexical_cast(T const& t) { return boost::lexical_cast<U>(t); } template<class T> inline T const& lexical_cast(T const& t) { return t; } Does it make any sense to put it in lexical_cast.hpp? -- Maxim Yegorushkin

Constrained genericity at last? (any interest in an operator traits/concept traits library?)
by Terje Slettebø 03 Oct '04

03 Oct '04

Colleagues: Are you tired of long and incomprehensible error messages when using STL, MPL, or some other modern template library? So am I! Up to now, we've had the Boost Concept Check Library, but unfortunately, you may still get long error messages with it (in the case of Intel C++ 6.0 and STLPort, pages and pages long, although the cause of the error is usually more clear, due to words like "concept_check", "function_requires", etc. showing up in the error message), and you can't overload on concepts, i.e. having several overloaded functions taking different kinds of iterators (such as std::advance). However, the invention of enable_if [HJW03] [JWL03] (now part of Boost) opened the door to overloading based on arbitrary properties of types. Now, what we needed was techniques for detecting type properties, which could be used to create "concept type traits". Using this, we could have done, e.g. for std::sort: template<class Iterator> typename enable_if<is_random_access_iterator<Iterator> >::type sort(Iterator begin, Iterator end) { // ... } Besides enable_if, there have also been other discoveries paving the way for constrained genericity (programming with concepts) in the later years. One of them being isAddable [KJSMA03], which could detect if there exists a "+" operator for the values "a" and "b" in "a + b", and gives a true/false result. The operator could be built-in, member function, or free function; it didn't matter. Other work on type property introspection in C++ has been done by other people, notably Paul Mensonides, with techniques for detecting member types, (non-static) member variables and functions, static member variables and functions, etc., using SFINAE to great effect. The original isAddable required exact overload match - no conversion on the arguments was allowed, so int + int gave true, but int + double gave false, even though 1 + 1.0 is well-formed - but using a modified version, it's possible to allow the normal promotions/conversions on the arguments, as well, letting int + double give true. In contrast, the other mentioned detection techniques requires an exact signature match, so these two ways complement each other: The exact match way may be used where the promotions/conversions way can't be used, and vice versa. Last spring (after the introduction of enable_if and isAddable) I realised that we now for the first time had discovered or invented all the components needed for a decent implementation of constrained genericity (or programming with concepts) in the current C++ language (as shown with the code example above)! I therefore started on a library of type traits for detecting the components required for concept checking, which meant detecting such things as operators, constructors (to the degree it's possible), etc. The modified isAddable is a key technique used in this "operator traits" part of the library. When this was complete, I continued with the "concept traits" part of the library, where the aim was to make type traits for all the C++ standard concepts, as well as all the Boost.MPL concepts (for the reasons that MPL is widely known and used, it's part of Boost, it could help a lot with better error messages in such metaprogramming libraries, and as an example of implementing non C++ standard concepts). I was about halfway done with the library last summer, and then I got a new job, where I became very busy, so unfortunately I couldn't continue with it at that time. However, a while ago, I've resumed work on the library, and it's now complete. Besides the mentioned enable_if, isAddable, and the introspection techniques, MPL is a core component of the library. Its lazy evaluation logical operators are indispensible for many of the concept traits, particularly the more complex ones. I couldn't have done it without any of you. Thank you. MPL is also used in the unit tests, generating the test matrix on the fly, testing each trait in a list against a list of types, and comparing the result against a table. The total number of tests generated is several thousand. Other approaches ------------------------- About a year ago, there have been proposals/discussion papers for adding support for concepts to the C++ language (see N1510, N1522 and N1536 at http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2003/) Using this, the above example could have been written as: template<RandomAccessIterator Iterator> void sort(Iterator begin, Iterator end) { // ... } This would also ease implementation of such concept overloading, because it would include the concept of concept refinement and "best match". Using the enable_if solution is a match or no match situation: either a function or class template matches, or it doesn't. Thus, if you want to implement std::advance as several overloaded functions using enable_if, you have to do something like this: template<class Iterator,class Distance> typename enable_if< mpl::and_< mpl::or_< is_input_iterator<Iterator>, is_output_iterator<Iterator> >, mpl::not_< is_bidirectional_iterator<Iterator> > > >::type advance(Iterator i,Distance d) { while(d--!=0) ++i; } The above function template is called if Iterator is either an InputIterator or OutputIterator, but not BidirectionalIterator (or "higher"). I.e. you have to manually exclude the next higher concept in the hierarchy, since BidirectionalIterator is also an InputIterator and OutputIterator (but should then call another overloaded function, not this one). If you also have a std::advance overload for BidirectionalIterator, you would otherwise get an error about ambiguity for the overloads (as they both would match), when called with a BidirectionalIterator. Nevertheless, the operator traits/concept traits library is something that can be used _now_, and which may give us more experience with programming with concepts. If the traits are used with libraries like STL or MPL, it has the potential to give drastically better diagnostics, and thereby making them easier to use. In addition, overloading on concepts is possible. A few of the traits (is_assignable, is_default_constructible and is_copy_constructible) rely on BCCL as a "last resort" when used for user-defined types, as there is no known way of detecting these for user-defined types. The library, including documentation, examples and tests may be found at (http://home.broadpark.no/~terjesl/operator_concept_traits.zip) (Yahoo Files is full, could we perhaps remove some of the stuff there that is now part of Boost?). Here's the synopsis from the documentation: Synopsis ------------- The library contains: - 46 operator type traits, covering all the overloadable (and therefore detectable) operators, as well as detection of default constructor, copy constructor and assignment operator. - 37 C++ standard concepts type traits, covering all the concepts of the C++ standard. - 19 Boost.MPL concepts type traits, covering all the documented concepts of Boost.MPL. - Facilities for defining your own concept type traits. - A complete set of unit tests. - Example programs, demonstrating its use. ------------- Some components may duplicate existing parts of Boost (such as MPL's has_xxx.hpp for member type detection, and mpl::is_sequence), and in other cases, the library includes functionality that may better belong in existing Boost libraries (type traits and MPL), and in those known cases, it's noted in the documentation. An aim is of course to syncronise the libraries, so that duplication is avoided. There may also be other components in the library that duplicate parts of MPL (or other parts of Boost) not noted here, and I'm all ears hearing about that, so that duplication may be eliminated. The operator traits/concept traits is essentially an extension to the Boost type traits library, but due to its specialisation (detecting operators, and generic concepts), as well as its size, it may be better to have as one or more separate components. Compatibility The library has been tested on Intel C++ 7.1, MSVC 7.1 and g++ 3.2. All tests pass on Intel C++ 7.1 and MSVC 7.1. For g++ 3.2, the operator traits tests pass, but most of the concept traits fails (either at compile time, or give wrong result). I intend to work to make the library work for g++ 3.2, as well.

For those who may be wondering where I've been all this time, the reason was the mentioned new job, which lead to me being away from more or less the C++ community for about a year, until a few months ago. P.P.S. I've also seen the last days there have been discussion on the Boost list on similar facilities (the "Proposal for 'is_dereferenceable' and other templatemetafunctions" thread started by Alex Chovanec). is_dereferenceable<T> is similar to this library's has_dereference_op<T> (in the operator traits part), except that the latter doesn't test for lvalue, etc. Moreover, some of the other existing functionality may work better than the corresponding ones in this library (like MPL's has_xxx.hpp, which, from the comments in the header file is able to detect reference member types, something this library can't), so maybe we could cooperate? P.P.P.S From libraries in the Boost Sandbox, it appears that it's ok, even common, for libraries that are not part of Boost to still use the Boost logo in the documentation. Therefore, that is done in this case, as well. I also hope John Maddock doesn't mind that I used the same kind of tables for these traits, and general style, as for the Boost type traits library. Feedback on this library is very welcome.

boost::threads' exceptions patch
by Rodolfo Schulz de Lima 03 Oct '04

03 Oct '04

Hi, I've been using boost::threads for some time now and found it to be very useful and elegant in design. The only problem I see is when it throws an exception. No information about the error is fed to the exception constructor, and all we have is a 'boost::thread_resource_error' or a 'boost::lock_error' in std::exception::what, not very helpful. Since boost::thread_exception has a constructor that accepts an error code, I've managed to patch some files and fed (where appropriate) the error code to the exception constructor so that we can have an idea of what is the cause of the exception when we catch it. Not being fully satisfied with the results (we never are), I went a little further and decided to make thread_exception inherit from std::runtime_error, and pass to its constructor an informative message about the exception. This way std::exception::what will show not only the exception class name, but also the reason of the error (if we have an error core). I've modified the other exception classes accordingly. The last thing I did was to remove thread_argument_error since we could use std::argument_error instead. In fact, this class is never used, and in the only place that it would be used, std::argument_error is used. I'd appreciate any comments about those changes... Regards, rod IMPORTANT NOTE: I've just changed the PTHREADS implementation... I do not have good background on winthreads and mptasks, so I count on anyone who knows those systems to update their implementation... // Patch follows Index: boost/thread/exceptions.hpp =================================================================== RCS file: /cvsroot/boost/boost/boost/thread/exceptions.hpp,v retrieving revision 1.14 diff -u -r1.14 exceptions.hpp --- boost/thread/exceptions.hpp 8 Sep 2004 15:57:03 -0000 1.14 +++ boost/thread/exceptions.hpp 2 Oct 2004 23:51:50 -0000 @@ -25,11 +25,11 @@ namespace boost { -class BOOST_THREAD_DECL thread_exception : public std::exception +class BOOST_THREAD_DECL thread_exception : public std::runtime_error { protected: thread_exception(); - thread_exception(int sys_err_code); + thread_exception(std::string message, int sys_err_code=0); public: ~thread_exception() throw(); @@ -48,8 +48,6 @@ lock_error(); lock_error(int sys_err_code); ~lock_error() throw(); - - virtual const char* what() const throw(); }; class BOOST_THREAD_DECL thread_resource_error : public thread_exception @@ -58,8 +56,6 @@ thread_resource_error(); thread_resource_error(int sys_err_code); ~thread_resource_error() throw(); - - virtual const char* what() const throw(); }; class BOOST_THREAD_DECL unsupported_thread_option : public thread_exception @@ -68,18 +64,6 @@ unsupported_thread_option(); unsupported_thread_option(int sys_err_code); ~unsupported_thread_option() throw(); - - virtual const char* what() const throw(); -}; - -class BOOST_THREAD_DECL invalid_thread_argument : public thread_exception -{ -public: - invalid_thread_argument(); - invalid_thread_argument(int sys_err_code); - ~invalid_thread_argument() throw(); - - virtual const char* what() const throw(); }; class BOOST_THREAD_DECL thread_permission_error : public thread_exception @@ -88,8 +72,6 @@ thread_permission_error(); thread_permission_error(int sys_err_code); ~thread_permission_error() throw(); - - virtual const char* what() const throw(); }; } // namespace boost Index: libs/thread/src/condition.cpp =================================================================== RCS file: /cvsroot/boost/boost/libs/thread/src/condition.cpp,v retrieving revision 1.20 diff -u -r1.20 condition.cpp --- libs/thread/src/condition.cpp 17 Jul 2004 04:33:59 -0000 1.20 +++ libs/thread/src/condition.cpp 2 Oct 2004 23:51:58 -0000 @@ -340,7 +340,7 @@ int res = 0; res = pthread_cond_init(&m_condition, 0); if (res != 0) - throw thread_resource_error(); + throw thread_resource_error(res); } condition_impl::~condition_impl() Index: libs/thread/src/exceptions.cpp =================================================================== RCS file: /cvsroot/boost/boost/libs/thread/src/exceptions.cpp,v retrieving revision 1.10 diff -u -r1.10 exceptions.cpp --- libs/thread/src/exceptions.cpp 8 Sep 2004 15:56:33 -0000 1.10 +++ libs/thread/src/exceptions.cpp 2 Oct 2004 23:51:58 -0000 @@ -69,12 +69,15 @@ namespace boost { thread_exception::thread_exception() - : m_sys_err(0) + : runtime_error("boost;:thread_exception") + , m_sys_err(0) { } -thread_exception::thread_exception(int sys_err_code) - : m_sys_err(sys_err_code) +thread_exception::thread_exception(std::string message, int sys_err_code) + : std::runtime_error(message+(sys_err_code==0 + ?

Re: como results?

Hi Bronek, > I have not stopped running regression tests on Comeau compiler; why > its results are no longer displayed on > http://www.meta-comm.com/engineering/boost-regression/developer/summary__re… They are in the reports, but because "como-win32-4.3.3-vc7.1" toolset is not marked as "required" in "status/explicit-failures-markup.xml", they are visible in the full view (http://www.meta-comm.com/engineering/boost-regression/developer/summary.html) but not the release view. The links at the top/bottom of each page allow you to switch between two. Currently, the toolset is marked as "required" if either of the following holds: 1) The compiler/configuration is known to be widely used, and/or the majority of Boost developers is committed to supporting it. The current versions of MSVC, Intel, GCC and CodeWarrior all fall into this category. or 2) The compiler/configuration is not widely used, but there are one or more Boost delevopers who consider it important enough to be included in the release criteria, and therefore volunteer to run regression tests for it, fix/mark up its failures, and generally take responsibility for driving things towards the release at reasonable speed. "intel-win32-7.1-vc6-stlport-4.5.3" is one such example. The only reason Comeau hasn't been marked as "required" so far is that it's unclear to me what its position is in regard to these two criteria. -- Aleksey Gurtovoy MetaCommunications Engineering
