catching all exceptions

Hi All,

I'm (still) using python 1.5.2 and I'd like to catch all exceptions in a
try block then find out what kind of exception excatly was risen and
save the output that would have been produced if I hadn't cought the
exception (or the stack-trace up to this position). Something like this:

try:
    do_something()
except (IOError, ...), value:
    this_exception = Exception_class
    ...
    write_Exception_to_database(this_exception, value)
    raise this_exception, value

The thing is that my program may raise all kinds of exceptions (not only
user defined exceptions), and I'd like to write the exception class (not
the Exceptions base class), the value, and the stack-trace up to this
point as one big string to a database before terminating the program.

currently I'm doing:

try:
  do_something()
except Exceptions, value:
  write_Exception_to_database('Python-Error: ' + repr(value))
  sys.exit(-1)  

with this I think I can catch all predefined exception classes, because
Exceptions is the base class for all other exceptions, but I realy want
to know which derived exception class was raised (and also the
stack-trace).

Is there (simple) way to do that in python (1.5.2)?

	thanks alot for help,

	Arne
