[leafnode-list] C++-ifying leafnode
Mathias mentioned some time back on this list that he was considering
to convert part of leafnode-2.0 to either C++ or Python or both.
Well, it is my pleasure to announce that I've started converting the
nntp server (nntpd.c) to C++. I'll do the conversion in stages,
1. Replace printfs with ostreams, C PODs with C++ data types where
applicable (essentially converting char * to std::string whenever
possible). The benefits of this are less chance of a printf-induced
buffer overflow, typesafe data conversions in the ostreams and
some reduction in the memory management complexity when using
2. Start converting the support library to use C++ data types like
strings, streams and potentially STL containers. At this point,
some of the other programs like fetchnews and texpire can also
start benefiting from the C++ support.
3. Change the structure of programs to take advantage of C++.
Currently I'm in phase 1 and part of the nntp server is
converted. I'll do the rest sometime this week and post the code on my
website - I'll send an announcement to the list once that's
done. The server is still stable :-) and although the C++ binary is
considerably bigger on FreeBSD compared to the C version I didn't
notice a performance degradation.
Please note that:
- the work is currently based on the 14/07 version of leafnode 2. I'm
usually a bit short of time so I can't always keep up with MA's
releases. I'll hope that we can get around this once the C++ bits
are reasonably stable.
- it doesn't integrate with the build system yet. I'm not very
familiar with autoconf so if anyone could extend the scripts to
support C++ then I'd be grateful. For the time being I'll include
a build script to compile the C++ code.
