Change checkpoint_data and restore_connection_on_error to subtransaction
checkpoint_data and restore_connection_on_error used to commit() and
rollback() the db connection. This causes additional I/O and load.
Changed them to use 'SAVEPOINT name' and 'ROLLBACK TO name' to get a
faster method for handling errors within a tranaction.
One thing to note is that postgresql (unlike SQL std) doesn't
overwrite an older savepoint with he same name. It keeps all
savepoints but only rolls back to the newest one with a given name.
This could be a resource issue. I left a commented out release
statement in case somebody runs into an issue due to too many
savepoints. I expect it to slow down the import but....

Debugging Aids -------------- Try turning on logging of DEBUG level messages. This may be done a number of ways, depending on what it is you're testing: 1. If you're testing the database unit tests, then set the environment variable ``LOGGING_LEVEL=DEBUG``. This may be done like so: LOGGING_LEVEL=DEBUG python -m pytest test/ This variable replaces the older HYPERDBDEBUG environment var. 2. If you're testing a particular tracker, then set the logging level in your tracker's ``config.ini``. SENDMAILDEBUG ============= Set to a filename and roundup will write each email message that it sends to that file instead to the internet. This environment variable is independent of the python -O flag.
