[SOLVED] Where's the rest of the IronPython exception?

Where's the rest of the IronPython exception?

I could be wrong, but it seems I'm only getting incomplete stack traces and exception messages when a SystemError is raised in IronPython. I'm doing this:

try:
    with SQLConnection(DATASOURCES[SCHEDULEDB]) as db:
        db.execute_sql( command + ' ' + ','.join(block) + ';' )
except Exception, e:
    print 'caught an exception'
    print "Unexpected error:", sys.exc_info()[0]
    print e
    raise
finally:
    db.close()
    engine.close()

However, all I'm seeing is this:

Traceback (most recent call last):
SystemError: The connection has been disabled.

Solution

Try:

import traceback
traceback.print_exc()

Instead of printing the exception object directly. In Python, exception objects don't hold onto the stack trace directly—instead they're part of the trio of items in sys.exc_info().

You could also do:

import System
...

except System.Exception, e:

and you'll get a normal .NET exception object instead of the Python exception object.
