Is it possible to monitor for exceptions using the Mac OS X catch_exception_raise function inside python? As you may know, after some setup, this function gets called whenever an exception occurs. I have a program which works great in C but when I wrap it in python it fails. This is due to the fact that it calls exc_server, which uses _dyld_lookup_and_bind, to try to find the location of the function catch_exception_raise. When wrapped in python, dyld_lookup_and_bind returns 0x2030 which is NOT the correct address. It then jumps there and tries executing which causes a BUS ERROR.
In C at least, dyld_lookup_and_bind works if the catch_exception_raise function is compiled into the binary or linked dynamically at runtime via a shared library (dylib). However, it doesn't work if it is brought into the executable space via dlopen - which presumably is how python does it. How can I set it up so that I can monitor applications for exceptions in a python script? I could fork and exec a program with its own address space, but that seems ridiculous. I could recompile the python interpreter and include catch_exception_raise, but that also seems terrible. Or is it impossible to wrap such a program in python - which seems silly? Any help is appreciated. Thanks, Charlie _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
