Better error handling

[mkolar]

Problem

We need to address error handling through pype. There are two issues:

One is complete user “un-friendliness”. Lot of errors ends up just as tracebacks printed to console (in better cases). For example running application on task on ftract that is not synced to avalon should end with error message saying so, not in “NoneType is not subscritable” or what.

Second is global error handling. We can utilize something like sys.excepthook to catch uncatched exceptions. At that point, try to collect logs from mongo and provide user with ability to report crash to us, or save it to archive and email it manually (default one for headless stuff like event-server)

merged in #474. We shhould add keyboard handler to handle ctrl+z

import sys
def my_except_hook(exctype, value, traceback):
    if exctype == KeyboardInterrupt:
print "Handler code goes here"
    else:
sys.__excepthook__(exctype, value, traceback)
sys.excepthook = my_except_hook
