Hi Gennadiy, Yes I would like to know how I need to write my own main in this case? Also I was wondering if there is any workaround that was found other than re-writing the main? Thanks, Deepa Here is what I am trying to do, may not be the best way, but trying to re-run the test suite ts1 - 3 consecutive times to test for repeatability: bool init_unit_test_suite(int argc, char **argv) { test_suite* ts1 = BOOST_TEST_SUITE( "SKUResourcesTestSuite" ); ts1->add( BOOST_TEST_CASE(&TestCase1) ); ts1->add( BOOST_TEST_CASE(&TestCase2) ); framework::master_test_suite().add( ts1 ); for(int i = 0;i < 3;i++) { framework::master_test_suite().add( ts1 ); } return true; } Deepa S <mslvada <at> yahoo.com> writes:

I am running into a similar issue and would like to know how to resolve it.
What exactly is the issue? Do you want to write your own main?

Message-ID: <52F88B4C.40707@gmail.com> Content-Type: text/plain; charset=UTF-8; format=flowed Hi! Recently I've been trying to improve the performance of a code that makes heavy use of std::string (lots of constructions and destructions). My first thought was to use boost::container::string as it does not use reference-counting and uses small-string optimization, so it should be a perfect replacement for std::string when it comes to performance. Right... But the problem is that switching to boost::container::string only made things worse in the general case. I wrote "in the general case" because when strings to be held are small and SSO may be applied then boost::container::string outperforms std::string considerably. However, in the general case constructing boost::container::string from a C string is significantly slower than constructing std::string. My investigation showed that std::string uses memcpy to copy the C string into its buffer while boost::container::string does not. The memcpy comes from std::char_traits::copy so maybe boost::container::string could use it too? I guess the rest of operations from std::char_traits (find, move, assign etc.) could be utilized too as std::char_traits has been carefully crafted with performance in mind. Should I create a ticket for this issue?

Yes, please. I'm slowly trying to benchmark and improve Boost.Container performance, I haven't started optimizing basic_string so your ticket could be a good start point. In a quick inspection I see that the constructor is dispatched to basic_string::assign(It, It) and that assignment is not optimized at all. I should definitely write a assignment function that dispatches to std::char_traits::copy, as it could be used to optimize several member functions.

Renaming ERROR to something else avoids this problem. I think I tracked it into ' boost/spirit/home/classic/iterator/impl/file_iterator.ipp' but I'm not sure where exactly it is coming from. Adi
