[spirit] tree_to_xml.cpp fails to compile on release branch
by Boris Gubenko 29 Jan '08

29 Jan '08

Just wanted to point out that spirit library tests tree_to_xml[_debug] added to the release branch on 2008-01-23 fail to compile on all the platforms. For the release platforms such as "acc" and "msvc-8.0", the spirit library is the only failing library on the branch. Thanks, Boris bash-3.00$ svn log -v -r {2008-01-20}:HEAD \ http://svn.boost.org/svn/boost/branches/release/libs/spirit ------------------------------------------------------------------------ r42926 | hkaiser | 2008-01-23 05:30:39 -0800 (Wed, 23 Jan 2008) | 1 line Changed paths: M /branches/release/boost/spirit/tree/impl/tree_to_xml.ipp M /branches/release/libs/spirit/test/ast_calc_tests.cpp M /branches/release/libs/spirit/test/numerics_tests.cpp Fixed bug #1595. ------------------------------------------------------------------------ r42927 | hkaiser | 2008-01-23 05:34:03 -0800 (Wed, 23 Jan 2008) | 1 line Changed paths: M /branches/release/libs/spirit/test/Jamfile.v2 A /branches/release/libs/spirit/test/tree_to_xml.cpp Added a new test. ------------------------------------------------------------------------ bash-3.00$

[spirit] tree_to_xml test failing on release branch
by Richard Webb 29 Jan '08

29 Jan '08

The (recently added) spirit/tree_to_xml test is failing on all the platforms on the release branch - for example http://tinyurl.com/34lwxf. The test is passing on Trunk. Does the release branch need fixing before the release? Thanks, Richard Webb

Where to download boost 1.33.0-1?
by Bo Xie 29 Jan '08

29 Jan '08

http://sourceforge.net/project/showfiles.php?group_id=7586&package_id=8041 only provides boost 1.33.0 download, not 1.33.0-1. Where to download boost 1.33.0-1? Boost 1.33.0-1 and 1.33.0 are the same or not? Thanks!

[variant]crtp variant seems to create 2 variants when only 1 needed.
by Larry Evans 28 Jan '08

28 Jan '08

The attached code attempts to use CRTP (Curiously Recurring Template Pattern) to see if recursive_variant can be avoided; however, I'm getting 2 variant's produced instead of 1 and the which gives the wrong result. The output is: <-- cut here -- /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/build/gcc4_1/lje/libs/variant/test/crtp_test.exe set_of_objects_tracked+ ===>Enter:int_list_1 scope object_tracked+:id=1:default ===>Enter:variant() /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1176:id=1 ===>Exit:variant() object_tracked+:id=2:default ===>Enter:template<typename T>variant(T& operand) /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1360:id=2 ===>Enter:template<typename T>convert_construct(T& operand,int,false) /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1268 /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/initializer.hpp:95:index=1 /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1280:after initialize:which=1 ===>Exit:template<typename T>convert_construct(T& operand,int,false) /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1362:after_convert_construct:which=1 ===>Exit:template<typename T>variant(T& operand) ===>Enter:template<class T>vlist(T) id=1 T.first=1 this->which=0 ===>Exit:template<class T>vlist(T) int_list_1.which()=0 object_tracked-:id=2:am_i_live=1 object_tracked-:id=1:am_i_live=1 ===>Exit:int_list_1 scope set_of_objects_tracked- >-- cut here -- The output produced from just the attached includes: this->which=0 but I expected which=1 since the CTOR arg is the 2nd bounded type: (pair<int,list_type*>). The other output's are produced by making object_tracked a super of variant and also putting debug prints in various CTOR's. The output: ===>Enter:variant() /home/evansl/prog_dev/boost-svn/ro/boost-trunk/sandbox/lje/libs/variant/test/variant.hpp:1176:id=1 ===>Exit:variant() indicates a variant produced with the default CTOR has id=1 which is the id of the vlist produced with the pair CTOR arg. Does anyone have any clue why this is happening, IOW why which=0 instead of 1. I tried using the debugger, but it was not more help. TIA. -regards, Larry

[ptr_container] Any plans to add ptr_unordered_set/map?
by Amit 28 Jan '08

28 Jan '08

Hi, An obvious question: Now we have unordered containers approved for 1.35, is the ptr_container library going to get the corresponding adapters as well for this release? I had a look in the svn trunk but only found disappointment... Ta Amit

[1.35] May I merge a low risk, low prio bug fix?

Hi May I still merge a bug fix to the release branch for 1.35, or is it already too late? The change is: Index: libs/statechart/example/Performance/Performance.cpp =================================================================== --- libs/statechart/example/Performance/Performance.cpp (revision 42908) +++ libs/statechart/example/Performance/Performance.cpp (working copy) @@ -62,6 +62,7 @@ #include <iostream> #include <fstream> #include <iomanip> +#include <ios> // for std::fixed #include <string> #include <algorithm> This is obviously low risk but it's also low priority, as the bug is in an example, not the library itself.

[announce] Dynamic object factory v2
by Marco Costalba 26 Jan '08

26 Jan '08

I have uploaded in Vault a new version of dynamic object factory that I consider much cleaner and nicer then previous one. Vault file name is factory_25_1_2008.zip An object factory it's a facility that gives you an object of a given class when requested to do so. A dynamic object factory it's a factory where the class of object to be created together with it's c'tor arguments are passed to the factory as run-time variables, populated as example reading from a file or listening on a net connection. The main difference with a static factory is that the latter falls short when at compile time there is not enough information about what and how many objects will be instantiated at run-time because it depends, typically, on some form of external information. The aims of this dynamic factory implementation are - Simplicity and clear code - Flexibility in number and types of c'tor arguments - Type safe both at compile time and run time - Fall back on static factory behaviour when object information is known at compile time. In this case query for object is 100% compile time resolved with zero runtime overhead and with complete compile time type checking - Full mimic of native new operator, in particular implicit conversions of c'tor arguments are fully supported according to C++ rules Tough factory would need some boost libraries I have implemented in the included file util.hpp a (very) stripped down versions of the few traits and type list facility needed. The goal is to let user to check the factory without requiring boost although function names strictly resembles the boost ones. A side effect is a greatly reduced compile time (and very fast because factory is really small) Factory in itself is 100% pure C++, absolutely no libraries are required, even no libstd++, only local headers are used. Actually test.cpp driver program uses <iostream> and <string> but just for the test framework. Please read test.cpp for usage documentation, although I hope that factory code is so simple that is self-documenting. Finally I have tested with success factory implementation on gcc3.4, gcc4.2, Intel 10.1, MSVC 2008 and even Comeau C++ Online :-) versions 4.3.1 and later. Of course comments are welcomed. Marco

[Boost.Test] return value of macros
by Thorsten Ottosen 26 Jan '08

26 Jan '08

Hi Gennadiy, I often want to output message or do additional test of another test fails. It would be cool if I could do it like this: if( !BOOST_CHECK_CLOSE( aStarEcr, close, 0.0001 ) ) { BOOST_MESSAGE( "\nA* sequence: " << aStarSeq ); BOOST_MESSAGE( "\nClose sequence: " << closeSeq ); } But, AFAICT, the macros are implemented this way: #define BOOST_CHECK_WITH_ARGS_IMPL( P, check_descr, TL, CT, ARGS ) \ do { \ BOOST_TEST_PASSPOINT(); \ BOOST_TEST_TOOL_IMPL( check_frwd, P, check_descr, TL, CT ) \ BOOST_PP_SEQ_FOR_EACH( BOOST_TEST_PASS_ARG_INFO, '_', ARGS ) ); \ } while( ::boost::test_tools::dummy_cond ) \ /**/ Do you think it would be possible have a bool returning function instead of the while loop? best regards -Thorsten
