problem with boost_unit_test : BOOST_CLASS_TEST_CASE seems no the access instance at the right address, on Mac OS X, with gcc 4.0.1/2 with optimization level > 0
by Ananda Tallur 06 Mar '06

Hello, I would like to submit a strange problem we recently discovered, when using boost_unit_test. This problem only occurs : on Mac OS X, when using gcc 4 with any optimization level other than 0 (-O, -O1, -O2, etc...). I have tested with gcc 4.0.1 (build 5250 coming with Apple XCode 2.2.1), and also gcc 4.0.2 delivered by darwinports, and the problem is the same. On the other hand, it works perfectly on Linux, with gcc 4.0.2 and optimizations. The problem : it occurs when using BOOST_CLASS_TEST_CASE. BOOST_CLASS_TEST_CASE executes a test method of a class/struct instance, so that the class/struct attributes can be used in the test. With a very simple class, named SampleTest, having only -> one int attribute "a" -> a single test function : void sampleTest (), which only displays value of "a" -> a test declared in boost test suite : BOOST_CLASS_TEST_CASE ( & SampleTest::sampleTest, instance), with instance being shared pointer to a instance of sampleTest, instanciated with a given value of "a" passed as constructor argument. It does not work on Mac OS X, with the conditions described above. Everything happens as if BOOST_CLASS_TEST_CASE was not using the correct address in memory for accessing the instance attributes data. Furthermore, the value displayed for a is wrong, but always the same, it is not random at all, which seems to mean that there is a shift in the memory adress being accessed. Below is the complete sample program, for reproducing the problem : ---- file boost_unit_test_gcc4_pb_sample.cpp --- #include <iostream> #include <boost/test/unit_test.hpp> using boost::unit_test_framework::test_suite; using boost::unit_test_framework::test_case; using namespace std; class SampleTest { public: SampleTest (int val) : a (val) { } int a; void sampleTest () { std::cout << "a : " << a << std::endl; BOOST_CHECK_EQUAL (a, 12345); } }; test_suite* init_unit_test_suite( int argc, char* argv[] ) { test_suite* test= BOOST_TEST_SUITE( "Sample test" ); boost::shared_ptr<SampleTest> instance (new SampleTest (12345)); test->add (BOOST_CLASS_TEST_CASE ( & SampleTest::sampleTest, instance)); return test; } ---- end-of-file boost_unit_test_gcc4_pb_sample.cpp --- * Command used for compiling : BOOST_PATH=<path-to-your-boost-install> /usr/bin/g++-4.0 -O2 -I${BOOST_PATH}/include -L${BOOST_PATH}/lib - lboost_unit_test_framework boost_unit_test_gcc4_pb_sample.cpp -o boost_unit_test_gcc4_pb_sample When compiled when the above command, and running the program on Mac OS X : export DYLD_LIBRARY_PATH=${BOOST_PATH}/lib ./boost_unit_test_gcc4_pb_sample The result is the following : ---- Running 1 test case...a : 13691 boost_unit_test_gcc4_pb_sample.cpp(18): error in " SampleTest::sampleTest": check a == 12345 failed [13691 != 12345] *** 1 failure detected in test suite "Sample test" --- We see that value of "a" is wrong. When compiled without optimization (-O0), and running, the result is : ---- Running 1 test case...a : 12345 *** No errors detected ---- Everything is right in this case. Has anyone some experience using Boost unit_test framework on Mac OS X, using gcc 4, and already experienced this kind of problems ? Any help would be greatly appreciated ! Regards, Anand

Any interest in a portable bitfields?
by Emile Cormier 06 Mar '06

06 Mar '06

First, I'd like to thank everyone who contributed to this wonderful library. We use Boost at work, and I'd like to contribute back. I've come up with a portable mechanism that allows the declaration of bitfields much like the way you do in C++. The syntax for using these bitfields is the same as that of C++ bitfields. My solution doesn't suffer from the ambiguity in C++ where you don't know whether the first bitfield starts at the most significant or least significant end of the word. It also doesn't suffer from the problem in C++ bitfields where the compiler can arbitrarily decide to align bitfields along word boundaries. This solution has been very useful to me when dealing with hardware registers and with 16-bit color formats. I am aware of the existance of std::bitset, but it doesn't handle groups of bits like bitfields do. If there's interest, I'll post some code here.

[math, Tru64, V2] compex_test failures
by Vladimir Prus 06 Mar '06

06 Mar '06

Markus, there's a failure of math/complex_test on Tru64: http://tinyurl.com/zu33q I can't make much of it, so I'd suspect that there's some "make floating point more accurate" option that's passed in V1, and not passed in V2. Unfortunately, CVS does not contain tru64cxx71-006 toolset, so I can't compare the command lines myself. Any change you'll run the test with V1 and V2 (with -a -n, to get just commnad lines), compare the compile command lines and tell me if there are any significant differences, or just send the command lines to me? Thanks in advance, Volodya

Hi, is_base_and_derived isn't working on Borland 5.8.1, as you can see if you compare the test results for 5.8.1 (http://tinyurl.com/nru5r) and 5.6.4 (http://tinyurl.com/mh4s9) The attached patch might fix it. Please, could someone with access to the compiler try it out? thanks, Daniel

Listener-Registry Pattern implementation
by Dean Michael C. Berris 05 Mar '06

05 Mar '06

Good day everyone, I have just uploaded a simple implementation to the vault of my proposed listener-registry pattern implementation. Let me explain how this is different from Boost.Signals: 1) It doesn't use MPL (yet) -- since because the pattern is quite simple, I have implemented it such that the listener class should be inherited, and a handle() method should be overridden by the specific listeners. This would change, once I start learning more about MPL -- which should make the implementation more flexible at compile time. 2) It maps inputs to processors, while Boost.Signals allows you to use a signal which maps to different slots (which are all called in turn, once the signal is invoked). The listener-registry pattern implementation defines a registry to which listeners register themselves -- the registry then does the routing of inputs to the listeners. Think event driven processing, where a listener listens for a specific event and is invoked only when the specific input is passed into the registry which it is registered to. 3) It currently only intends to receive a single input type, which should change as I learn more about the MPL and how to make it more extensible with regards to compile time specification. The file is up at the vault (listener.tar.gz) and unfortunately, I chose to use the CppUnit test framework, and the GNU Make build system -- I've tried it on Ubuntu Linux 5.10, and requires libcppunit to build the test case. Comments, suggestions, and pointers most appreciated. Thanks, and hope to hear from you guys soon. -- Dean Michael C.

[tuple] Explicit member template function instantiation
