Description

If config load_minigraph crashes (e.g., due to an improperly formatted minigraph file), it can leave the ConfigDB in a broken state that requires manual intervention to recover from (i.e., database is completely empty; CONFIG_DB_INITIALIZED key is missing). ConfigDB should never be left in a broken state, even if config load_minigraph should crash.

For more context, see: sonic-net/SONiC#145

Steps to reproduce the issue:

  1. Modify /etc/minigraph.xml in order to create an improperly-formatted minigraph file (one that will cause the minigraph parser to crash)
  2. Run config load_minigraph, ensure it crashes while parsing (you will see Python backtrace)
  3. Check contents of ConfigDB (`redis-cli -n 4 keys '*'); DB will be empty.
