[Function Types] Review Reminder - just this weekend left for your reviews.
by John Maddock 17 Jun '05

17 Jun '05

This is to remind everyone that we have a review going on at present for Tobias Schwinger's Function Types library. The review period is due to end on the 20th June, which gives everyone just this weekend to take a look at Tobias submission, I'd really like to encourage as many folks as possible to take a look: if necessary we'll also extend the end of the review period if there's demand or to cope with late reviews. We'd particularly like to hear from potential users of this library. Here are the details again: Available from the sandbox at: http://boost-sandbox.sourceforge.net/vault/ or the zip file is: http://boost-sandbox.sourceforge.net/vault/index.php?action=downloadfile&fi… This library provides a metaprogramming facility to classify, decompose and synthesize function-, function pointer-, function reference- and member function pointer types. For the purpose of this documentation, these types are collectively referred to as function types (this differs from the standard definition and redefines the term from a programmer's perspective to refer to the most common types that involve functions). The classes introduced by this library shall conform to the concepts of the Boost Metaprogramming library (MPL). The Function Types library enables the user to: * test an arbitrary type for being a function type of specified kind, * inspect properties of function types, * view and modify sub types of an encapsulated function type with MPL Sequence operations, and * synthesize function types. This library supports variadic functions and can be configured to support non-default calling conventions. (The following is taken from : http://www.boost.org/more/formal_review_process.htm ) Here are some questions you might want to answer in your review: What is your evaluation of the design? What is your evaluation of the implementation? What is your evaluation of the documentation? What is your evaluation of the potential usefulness of the library? Did you try to use the library? With what compiler? Did you have any problems? How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? Are you knowledgeable about the problem domain? And finally, every review should answer this question: Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. John Maddock (Function Types review manager).

Re: [boost] Header error using boost.regex 1.32 built using vc6

Sorry to waste your time. Putting "using namespace std;" before including a boost header ought to be legal. I would regard it as a bug if a boost library failed because of a preceeding "using namespace std;" ON A STANDARDS CONFORMING COMPILER. On the other hand, VC6 is very far from a standards conforming compiler, so it seems perfectly reasonable to require users not to do that. It would be nice if there was warning somewhere in the documentation "that error means you have done this, and we can't cope if you have to use VC6". -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434

Header error using boost.regex 1.32 built using vc6
by Martyn Woerner 17 Jun '05

17 Jun '05

Hi Folks, I'm a newbie gingerly moving over from MFC. I have built and installed regex from the boost_1_32_0 package without any obvious problem. Now I've included the simplest use of regex taken from the overview and: a) I get a compile error in regbase.hpp. As a temporary workaround I've tried using V3 instead and: b) I get a link error (debug & release) Can someone help me overcome this please? Many thanks. I have: #include <boost/cregex.hpp> //#define BOOST_REGEX_V3 #include <boost/regex.hpp> using namespace boost; ... // regexp test const std::string s = "sdflsjhslad"; static const boost::regex e("(\\d{4}[- ]){3}\\d{4}"); if (regex_match(s, e)) ASSERT(true); else; ASSERT(true); ... which gives the following: Compiling... StdWbApp.cpp c:\projects\boost_1_32_0\boost\regex\v4\regbase.hpp(120) : error C2955: 'collate' : use of class template requires template argument list c:\program files\microsoft visual studio\vc98\include\locale(67) : see declaration of 'collate' c:\projects\boost_1_32_0\boost\type_traits\detail\wrap.hpp(16) : fatal error C1506: unrecoverable block scoping error and if I use V3 I get the link errors: StdWbApp.cpp Linking...

fstream_test.cpp won't compile using VC++ 6.0
by Jason Heyes 17 Jun '05

17 Jun '05

I receive errors when I try to compile fstream_test.cpp using Microsoft Visual C++ 6.0. The first error I receive is this: fstream_test.cpp c:\boost\include\boost-1_32\boost\filesystem\fstream.hpp(29): error C2504: 'basic_filebuf<char,char_traits<char> >': base class undefined c:\projects\examples\fstream_test.cpp(27): see reference to class template instantiation 'boost::filesystem::basic_filebuf<char,char_traits<char> >' being compiled Is there a workaround for this? Thanks.

lexical_cast update + Boost.Test question
by Terje Slettebø 16 Jun '05

16 Jun '05

Hi. lexical_cast has now been updated in the CVS, with the following, as has been reported as bugs or suggested improvements: - Fixed so it doesn't trim any whitespace when converting (it used to throw on " 123" -> int, but not on "123 " -> int, which was inconsistent). - Fixed reversed bad_lexical_cast constructor arguments. - lexical_cast now uses pass-by-const reference. For compilers lacking support for partial specialisation of class templates (like MSVC 6), it falls back on pass-by-value. Sorry for the late update. It's been quite busy at work lately, so it's been hard to concentrate on non-work projects, but I'm now more on top of things. I'll read up on any lexical_cast-related postings, and can make subsequent updates, should it be desired. I'll also check up the results after the next regression test run, to see if there are any remaining issues. The changes are of course done in cooperation with Kevlin. It has been tested on Intel C++ 7.1, MSVC 2005 Final Beta, g++ 3.4 and Borland C++ Builder X, and all tests pass there. I get errors (from Boost.Test) when trying to run the test on MSVC 6, but testing lexical_cast by itself seems to work. Might Boost.Test have a problem with MSVC 6? By the way, I don't see the changes using the Boost ViewCVS, but it's listed e.g. with "log". Are the ViewCVS results cached, somehow, or may the commit have ended up on some other place than the trunk? I did make sure to check out the trunk, before commit. Regards, Terje

[test] missing friend declaration in class fixed_mapping?
by Markus Schöpflin 16 Jun '05

16 Jun '05

Hello, I'm not really sure but isn't there a friend declaration missing in the fixed_mapping class? Given the following code: template< ... > class fixed_mapping { typedef std::pair<Key,Value> elem_type; ... struct p1 : public std::binary_function<elem_type,Key,bool> { bool operator()( elem_type const& x, Key const& y ) const { return Compare()( x.first, y ); } }; ... }; doesn't this require p1 to be a friend of fixed mapping to be able to access elem_type in it's operator()? This would then give: template< ... > class fixed_mapping { typedef std::pair<Key,Value> elem_type; ... struct p1; friend struct p1; ... struct p1 : public std::binary_function<elem_type,Key,bool> { bool operator()( elem_type const& x, Key const& y ) const { return Compare()( x.first, y ); } }; ... }; Markus

[test] Non-standard preprocessor directive used
by Markus Schöpflin 16 Jun '05

16 Jun '05

boost.test currently uses the warning preprocessor directive which isn't defined in the standard. This causes warnings by the compiler. cxx: Warning: /src/boost-HEAD/boost/test/impl/execution_monitor.ipp, line 60: #11-D unrecognized preprocessing directive # warning Debugger check disabled. Either define _WIN32_WINNT or include Boost.Test header in front of winbase.h -------^ Might it make sense to use #error instead? Markus

reset_and_collect root determination and sp_collect similarity
by Larry Evans 16 Jun '05

16 Jun '05

Hi Peter, The code here: http://lists.boost.org/boost-users/2005/05/11805.php appears to require the user to specify the root pointers in order to do a complete collection. This is in contrast to sp_collect.cpp which used Christopher's method [chri84] cited here: http://www.cs.kent.ac.uk/people/staff/rej/gcbib/gcbibC.html to find the roots, at least AFAICT. Is this intentional, or is the above code in 11805.php simply a sketch of a method which will eventually use something like Christopher's. I ask because some of the code in 11806.php appears similar to some in sp_collect.cpp. For example, I'm guessing that the map2_type in sp_collect corresponds to the map_type in reset_and_collect, i.e. the key is sorted on the referent, and the value is the number of smart_ptr's to that referent that are on the heap. Thanks for any clarification. -regards, Larry
