Uninitialized storage container to delay construction?
by Aaron W. LaFramboise 03 Jun '07

03 Jun '07

Does Boost have some sort of uninitialized storage container? Presently, I use this pattern if I want to delay construction of a sub-object. class my_class { public: my_class() { // ... subobject = auto_ptr<type>(new type(params)); } private: auto_ptr<type> subobject; }; But I'd like something similar that didn't use the heap, but instead allocated the storage for the sub-object within the class object itself. Perhaps it would look like this. class my_class2 { public: my_class2() { // ... subobject.construct(params); } private: uninitialized_container<type> subobject; }; A TR1 array<T, sizeof(T)> almost works, except for these points: (1) It doesn't provide proper alignment guarantees. (2) It doesn't call the destructor when it is destroyed. So, does Boost have any such thing?

[string algorithms] Failing on HEAD for all platforms
by AlisdairM 03 Jun '07

03 Jun '07

string algorithms is currently failing all tests on all platforms on CVS HEAD. AFAICT, the problem is that the string algo tests call the range library begin/end functions with raw character pointers, I guess looking for this to turn into a range by use of strlen or similar. The range library flags a compile failure trying to form C::const_iterator where C -> char *. I also see the range library has appropriate overloads for fixed-length arrays, and does not handle arrays of unknown size. I don't know if these fails are due to changes in the range library or string algorithms, so I'm not sure what to suggest as a patch yet. Any comments from the library authors appreciated (even if it is simply pointing to a previous discussion I have missed) -- AlisdairM

Unfortunately I wasn't able to attend Boost Con this year. Is there any materials from the presentations? Videos, white papers, power points? Thanks, Michael Marcin

typo in boost header: date_time/time_defs.hpp
by Sunil Rao 02 Jun '07

02 Jun '07

Hello, I'm writing to report a small typo a colleague of mine has discovered in the time_defs.hpp header in the date_time library. [Apologies if this is a known issue: I wasn't able to find any specific reference to this in any of the list archives.] http://boost.org/boost/date_time/time_defs.hpp The specific issue is in the time_resolutions enum: "hundredth" is misspelt as "hundreth". Hope this helps -sunil

[regex] empty expression issue
by impulse9 02 Jun '07

02 Jun '07

Hi All, I've just started to use boost::regex I met with the following incompatibility with Perl regular expressions: It is impossible to use empty expressions, neither alone nor inside of another regex statement. Sample code: #include <iostream> #include <boost/regex.hpp> void check_regexp(const char * text) { try { boost::regex e("(\\d+)\\s*(kbit|)"); boost::cmatch what; if (boost::regex_match(text, what, e)) { std::string item1(what[1].first, what[1].second); std::string item2(what[2].first, what[2].second); std::cout << "matched. " << std::endl << "Value : " << item1 << std::endl << "Units : " << item2 << std::endl << std::endl; } } catch (boost::regex_error & e) { std::cout << "ERROR: " << e.what() << std::endl; } } int main(int argc, char** argv) { check_regexp("96 kbit"); } Program output: ERROR: Empty expression Such regular expressions are quite legal in Perl (e.g. /(Ann|Bob|)/) One possible (quick-n-dirty) workaround for this is to replace boost::regex e("(\\d+)\\s*(kbit|)"); with boost::regex e("(\\d+)\\s*(kbit|.{0})"); Program output would be: matched. Value : 96 Units : kbit Would it be considered as an issue for further improvement? Thank you. -- impulse9
