#
# dbsocket_crash.py
#
# A simple test client application which checks that the
# client API also stops when the main application crashes
#
# This attempts to cause bug #2003 reproducibly.
#
# This script contains an intentional bug, it tries to call
# a function which is not defined. If the bug is present
# then the process will not end when the bug is encountered
# and the UNIX "kill" command will be required to end the
# process.
# If the bug is fixed then the process will stop when the
# undefined function is invoked.
#
# Usage:
# > python dbsocket_crash.py <project> <job_id>
