cathing uncaught exceptions

how can I catch (globally) exception that were not caught in a try/
catch block in any running thread? i had this weird case that an
exception was raised in one thread, but nothing was displayed/logged.

I suspect that your weird case was *not* because your exception was
uncaught, but because it *was* caught and just discarded. Look
through your code for something like this:

except ExceptionIDontExpectToEverGet:
pass

or even worse:

except:
pass

I'll bet one of these was your "exception non-logger" culprits.

sorry, no... i used except: print 'something' to validate that there
is an exception that was raised :). otherwise, i avoid your second
construct in my code (just because I don't want to miss strange cases
like this one).

I found that normally sys.excepthook is invoked for uncaught
exceptions. however in my case the function is not invoked (as it
should normaly do). i printed the stackframe and checked that there is
no try/catch block that handles the exception. any other idea?

Any chance you might have missed the word "raise", e.g.

except Exception, err:
Exception(err)

vs.

except Exception, err:
raise Exception(err)

This is from the list of stupid things I have done myself,

Each thread should handle its own exceptions. If any exception escapes from Threading.run(), it is printed on sys.stderr (sys.excepthook isn't involved); see the threading.py module for details.
Maybe you had a bare try/except that did nothing? or maybe you redirected sys.stderr?
