[asio] How to write custom async event provider
by Vaclav Vesely 24 Mar '06

24 Mar '06

Hi, I'm very impressed with Asio library proposal. What I'm missing is a description (or even tutorial) about creating custom asynchronous providers. I have an object which don't sends events, but I have to ask it for events. I have to create a thread for for this task. What I want to do is an Asio wrapper for this object that will create the worker thread behind and will dispatch events through Asio demuxer. Can you point to an documentation, example or something what will help me? Thank you in advance. Regards, Vaclav

[python] [BBv2] Solaris doesn't need -lutil
by Caleb Epstein 24 Mar '06

24 Mar '06

http://tinyurl.com/ftcyb I believe -lutil is needed for openpty on Linux, but there is no -lutil on Solaris and probably other OSes. It looks like this falls out of a change to tools/python.jam from yesterday. Can't we just do what Martin suggested and just use Python's distutils configuration to generate the library list? It seems like Cygwin would be the only special case then. Here's what I get on my Solaris system: % python -c "import distutils.sysconfig; print distutils.sysconfig.get_config_var('LIBS')" -lresolv -lsocket -lnsl -lrt -ldl And on a RedHat AS3 system: -lpthread -ldl -lutil -- Caleb Epstein caleb dot epstein at gmail dot com

[serialization] possible bug writing to text_oarchive
by rodolfo＠rodsoft.org 24 Mar '06

24 Mar '06

Hi, I use boost::serialization a lot to marshall c++ structures to be sent to a socket, like this: void send_update(ostream &out, const data_t &data) { { text_oarchive oa(out); oa << data; } out << "220 OK" << endl; } The problem is that text_oarchive doesn't append a blank character to denote the end of its data. If the last member sent to the oarchive is an unsigned 123 number, in this example the data sent would be ... (begining of data)... 123220 OK<CR> When processing this with text_iarchive, the last member gets the value 123220, instead of 123. By appending an space (or \n) to the end, in ~text_oarchive, this problem is solved. Another worst problem is if the receiver uses blocking socket connection (and no 220 OK is sent). After reading the last digit (3), it would wait for the next one, which wouldn't arrive, blocking the connection. By having an space after the last digit, it would know that the data stream has ended and it wouldn't block anymore. I've wasted the whole day figuring why my application was blocking :( Thanks, Rodolfo Lima _______________________________________________________ Yahoo! Acesso Gr�tis - Internet r�pida e gr�tis.

Building Boost 1.31 for x64 with Visual Studio 2005
by Terence Wilson 23 Mar '06

23 Mar '06

I've successfully built the 32 bit libraries for Windows, however, I cannot figure out how to build for 64 bit Windows. I'm particularly interested in using the serialization libraries. After Googling around I found a few others asking about x64, but no definitive answers. Help much appreciated.
