Accurate, pauseless & deterministic GC for C++
by Mingnan Guo 29 Nov '07

29 Nov '07

Hi all, The HnxGC Library for C++ is released at http://hnxgc.harnixworld.com This garbage collector provides accurate, pause-less (lock-free, block-free) concurrent garbage collection with deterministic reclamation for C++ application. Efficient, portable, no need registeration of root set pointers, no scanning of root set area, and more. Precompiled binary and source are available. Welcome any discussions and comments. -Mingnan Guo --------------------------------- Get easy, one-click access to your favorites. Make Yahoo! your homepage.

Config patch to fix bug #802 --- BOOST_DISABLE_THREADS and /Za on MSVC
by Anthony Williams 29 Nov '07

29 Nov '07

Since the boost thread headers can now be used without including <windows.h>, can I commit the following patch to boost/config/suffix.hpp in order to stop BOOST_DISABLE_THREADS being defined just because the user specified /Za on the command line? There was a discussion about this back in May, but I don't remember there being a definite outcome.

[lexical_cast] Specializations
by remi.chateauneu＠gmx.de 29 Nov '07

29 Nov '07

Hi, Are there lexical specializations such as (approximately): template<long, std::string> long lexical_cast( const std::string & refStr ) { return atoi( refStr.c_str() ); } This is of course less strict and clean as the general templates, but may be faster, with smaller code, given there are very fast implementations of atoi. This can be easily generalized to strtod() etc... Thanks.

xpressive and white space skipping
by Jorge Lodos Vigil 29 Nov '07

29 Nov '07

Hi We are using xpressive with a grammar to match certain patterns. In some cases, we have the need to ignore white spaces. Using dynamic regexes, this can be achieved with the ignore_white_space constant. Is there a way to ignore white spaces using a grammar in xpressive other than modifying the grammar itself? We know spirit is an option, but we need to evaluate parsing speed with as many methods as possible. Thanks in advance. Cheers Jorge

Is there any interest in a casting library where you don't need to specify a type of receiver?
by Sergey Shandar 29 Nov '07

29 Nov '07

Hello all I have my own C++ framework (http://cbear.berlios.de, SVN: http://tools.assembla.com/svn/cbear/trunk/) which has some useful (IMHO) libraries. One of this library is "cast" library (http://tools.assembla.com/cbear/browser/trunk/cbear.berlios.de/cast) which allows you to convert objects without specifying a type: char c; int i; ... // if(c == static_cast<char>(i)) if(c == cast::static_::value(i)) { ... } It is useful when you want to convert an object to a type of another object. And this is also more safe, compare to standard casting, for example in previous code someone can change the type of c to wchar_t, and if you use static_cast, the compiler will not even warn you about incorrect casting. So, you have to manually check all the code. Currently there are several castings: static, reinterpret, const, dynamic, polymorphic (based on Boost.polymorphic_cast), polymorphic_down (based on Boost.polymorphic_downcast), explicit (calls an explicit constructor), safe_reinterpret (compare sizes of converting types), default (returns an object created by default constructor). Thank you. Best regards, Sergey Shandar.

[dataflow] version 0.8.1: runtime reflection, dataflow network modeling via BGL...
by Stjepan Rajko 29 Nov '07

29 Nov '07

Hello everyone, I have uploaded a new version of the dataflow library to the vault (in the Dataflow directory), and updated the docs at: http://dancinghacker.com/code/dataflow/ The new version introduces the Dataflow.Blueprint layer, which provides runtime reflection of components/ports, as well as modeling and analysis of dataflow networks via BGL. This new layer is still full of hacks, its documentation is limited to a messy example, but I'm excited about having started it. This version also has some documentation updates and some additional examples (such as a little image processing dataflow example using Boost.GIL). If anyone is interested, my roadmap to requesting review looks like this: * add lots and lots of docs. * bring the Dataflow.Blueprint to some reasonably usable state. * move functionality from the overabused Port-related concepts into the Component concept, which should clean up and simplify the concepts dramatically. With this, I think the library will be in decent shape to request a review (it will have one dataflow framework modeling the generic concepts - Dataflow.Signals, and one layer built on top of the concepts, - Dataflow.Blueprint). My goal is to get there in the next month (which is only 5 months after GSoC close! :-)) By the time it actually gets to be reviewed, I hope to also add in another dataflow framework that would in some way address the things currently missing from this library (there are many). Any feedback is appreciated. Thanks to Phil Endecott, Pavel Vozenilek, John Torjo, Roland Schwarz and Neal Becker for their helpful feedback on the previous version. Regards, Stjepan
