Hi I don't know if this is the done thing or not, but since the subject of moribundity and other libraries has come up in the log4cxx mailing-list, I'd like to draw people's attention to a new logging _API_ library that myself and a colleague have recently released to the public domain: Pantheios (http://pantheios.sourceforge.net/). As the website explains, this comes with its own basic logging transport facilities. But it is really a flexible/extensible, 100% type-safe, and very efficient (see http://pantheios.sourceforge.net/performance.html) layer that can be used over the rich transport facilities of any existing logging library, including log4cxx or log4cpp. We've an article coming out soon on The C++ Source (http://artima.com/cppsource/) which will introduce it to the C++ world, so to speak. But since the subject's been raised in the log4cxx forum, I thought I'd give it a mention now. The current beta contains two examples in which log4cxx (examples/cpp/example_cpp_wrap_3pty_log_lib) and log4cplus (examples/cpp/example_cpp_wrap_log4cplus) are wrapped. If anyone with particular expertise with log4cxx, log4cplus and log4cpp would be willing to lend a hand in producing actual bindings to these libraries, we'd be very grateful. (Note: you can still use NDC's and all that stuff from within application code, so Pantheios+log4XYZ offers the best of both worlds.) Thanks for listening.

Ah, silly me! > Where can I get perfomance test sources? I've been meaning to add that into the distro for ages, but keep forgetting. I'm planning another beta (1.0.1. beta 10) tomorrow. I will include it with that. > I really can't understend how you library can outperform log4cpp in any test provided. Well, if a given logging level is switched off, there're no conversions, no strlen(), no strcpy(), no memory allocations: in fact, no actions of any kind, other than the severity test itself - pantheios::isSeverityLogged().

I do want to stress that Pantheios is not conceived as a replacement for other logging libraries, since it has only rudimentary transport of its own. The intention is that the flexibility, robustness and performance is a complement to the rich transport facilities of ACE, log4cpp, log4cplus, log4cxx, etc. In other words, we're not trying to trespass on log4cpp or steal its users. :-) Cheers Matthew |
