[boost] [Backtrace] Any interest in portable stack trace?

20 Oct 2010

      Hello, 

Is there any interest in getting portable stack trace to boost - get
something similar to Java's printStackTrace.

Basics:

  1. Getting stack trace of return pointers
  2. Converting this pointers to human readable trace 

Extras:

  1. Create exception classes that capture stack trace on throw (only pointers)
  2. Print a trace on catch

Supported Platforms: 
   Linux, Mac OS X, Solaris and Windows >= XP using MSVC.

Tested on:

   Linux x86_64, GCC,
   Linux x86, GCC
   Linux x86_64, Intel
   Windows XP 32bit, MSVC 2008

How implemented:

Linux/Mac/Solaris with GCC:

   Capture trace using backtrace
   Convert trace using dladdr + with demangling
   Requires: compilation with -rdynamic for fetching symbols

Linux/Mac/Solaris with Other compilers:

   Capture trace using backtrace
   Convert trace using backtrace_symbols (no demangling)
   Requires: compilation with -rdynamic for fetching symbols

Windows/MSVC

   Capture trace using RtlCaptureStackBackTrace (XP and Above)
   Convert trace using dbghelp.lib using SymFromAddr 
   Requires: debug info (PDB files) for fetching symbols

All other:

   Create an empty trace 

For example:

    #include <boost/backtrace.hpp>
    #include <iostream>

    int foo()
    {
        throw boost::runtime_error("My Error");
        return 10;
    }

    int bar()
    {
        return foo()+20;
    }

    int main()
    {
        try {
            std::cout << bar() << std::endl;
        }
        catch(std::exception const &e)
        {
            std::cerr << e.what() << std::endl;
            std::cerr << boost::trace(e);
        }
    }

Prints:

    My Error
    0x403fe1: boost::stack_trace::trace(void**, int) + 0x1b in ./test_backtrace
    0x405451: boost::backtrace::backtrace(unsigned long) + 0x65 in 
./test_backtrace
    0x4054d2: boost::runtime_error::runtime_error(std::string const&) + 0x32 in 
./test_backtrace
    0x40417e: foo() + 0x44 in ./test_backtrace
    0x40425c: bar() + 0x9 in ./test_backtrace
    0x404271: main + 0x10 in ./test_backtrace
    0x7fd612ecd1a6: __libc_start_main + 0xe6 in /lib/libc.so.6
    0x403b39: __gxx_personality_v0 + 0x99 in ./test_backtrace
