[ping] The review of Intrusive library started March 12
by Joaquín Mª López Muñoz 16 Mar '07

16 Mar '07

As we approach the mid review of Ion Gaztañaga's Intrusive library, I would like to encourage you to consider submitting your review reports. So far we've received three reviews only, I hope more Boost members step in and contribute to this global effort which constitutes the cornerstone of Boost renowned quality standards. If you love and use Boost, remember that active involvement is a nice way of repaying the benefit you have obtained from this community. If you plan to submit a review before the deadline but are still working on it, I'd appreciate receiving a short notice so that I can estimate the final number of reviewers. Also, if you'd like to do a review but can't do it on time, please let me know so as to consider the possibility to ask for a period extension. The Review Manager, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

I might consider converting this in to DocBook format if it becomes useful for me. Btw, how widely is the Boost Unit testing library used?

As an aside could the class documentation not be generated directly from the source using something like Doxygen?

[Boost-bugs] [ boost-Feature Requests-1681992 ] provide detach() function for shared pointer

Category: smart_ptr Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Peter Dimov (pdimov) Summary: provide detach() function for shared pointer Initial Comment: I suggest that we should provide a new method T* detachPtr() for shared_ptr to let the shared_ptr pass owner ship to other fuctions or applications. It is a comman case that user will have to let the share_ptr give up the owenership of the objec, pass the object to other application let that application take care the objcet's life. But there is no method to do so. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=357586&aid=1681992&group_… ------------------------------------------------------------------------- Take Surveys.

There is your answer. The running time of radix quicksort is k + 2N ln N, where N is the number of keys, and k is the number of bytes. Normal quicksort has a running time of k(2N ln N), with the same variables. To answer your question for radix sort, you would not use it for strings. If you did, however, then the number of collection times would be kN, where k is the number of bytes and N is the number of items.

Any interest in a sorting library with a multitude of sorts?
by Sam Schetterer 16 Mar '07

16 Mar '07

This sorting library would have quicksorts, radix quicksorts, radixsorts, mergsorts, a sorted-array class, and an interface class to be inherited from to allow sorting. _________________________________________________________________ Find a local pizza place, movie theater, and more.then map the best route! http://maps.live.com/?icid=hmtag1&FORM=MGAC01

[Sorting Library] Implementation of sorting API
by Sam Schetterer 15 Mar '07

15 Mar '07

Earlier, I asked if users would like to be able to define their own operators of if they wanted to redefine functions inherited from a interface class. I have decided to have users define their own operators because it is simpler, uses less space, is faster, and the sorting functions are easier to understand.

Bug in boost::filesystem (1.33.1)
by Jorge Lodos 15 Mar '07

15 Mar '07

Hi The function BOOST_FILESYSTEM_DECL path system_complete( const path & ph ) in operations_posix_windows.cpp contains the following code: char buf[MAX_PATH]; char * pfn; std::size_t len = ::GetFullPathNameA( ph.string().c_str(), sizeof(buf) , buf, &pfn ); if ( !len ) { boost::throw_exception( filesystem_error( "boost::filesystem::system_complete", ph, "size is 0" ) ); } buf[len] = '\0'; If the full path name is larger than MAX_PATH, the last line will cause a buffer overflow. This bug is not present in 1.34. Best regards Jorge Lodos

by Dean Michael Berris 15 Mar '07

I just noticed that the WARNING for WIN32 users of BoostBook points to an old URL of the xslt-proc for win32. Attached is a trivial patch to change the warning. -- Dean Michael C. Berris http://cplusplus-soup.blogspot.com/ mikhailberis AT gmail DOT com +63 928 7291459
