Distributed reverse / forward proxy and tunneling solution for TCP.
PortFusion is a minimalistic, cross-platform, transport-layer distributed reverse / forward proxy for TCP written in Haskell + LLVM and released under GPLv3. A single package that makes the most of each platform by tapping into their unique capabilities, combining this power with an intuitive interface, beautiful design and Haskell's excellent support for unprecedented levels of concurrency and parallelism. It strives for the smallest source code size (< 500 lines) while delivering maximum throughput with near zero overhead.
C++ exception (and generic) stack trace library (now libinstrument)
Project is migrating to libinstrument (https://sourceforge.net/projects/libinstrument/) Libcsdbg is a C++ exception stack tracer, offers the tools to create and process exception traces, the path an exception has propagated up the call stack, unwinding it, up to the point where it was handled. The traces are detailed with demangled function signatures and addr2line info (source file and line of each function call). Libcsdbg will perform flawlessly with multi-threaded programs, with dynamically linked shared objects (DSO) and with any statically linked library. Libcsdbg helps the developer/tester also create stack traces of any thread, at any point during, as a snapshot of the runtime call graph. This is very useful in cases of fatal errors, reception of terminating signals or process abortion/termination (such as segmentation faults)
