Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Re: Thread safety problem: msg#00019

apache.logging.log4cxx.user

Subject: Re: Thread safety problem

Hello,
thank you for your answer.
I was wondering why there where no problem with std::cout, while there was with log4cxx::stream...
if internal is synchronised, it shouldnt crash and have the same behavior as std::cout, no?

For example:

Log::stream<<"message"<<LOG4CXX_ENDMSG;

is equivalent to:

Log::stream.operator<<("message");
Log::stream::operator<<(LocationFlush(__FILE__, __LINE__, ...));

Even if all operator<<'s had internal synchronization, you could still have other calls to the same logstream occurring between the insertion of "message" and the insertion of the LocationFlush object which triggers the call to Logger::debug().


of course it can maybe not preserve my intent....i could not get the message i was thinking to... but it shouldnt crash, no?

regards
