Custom dataset location impossible?

[dmtvanzanten]

Steps to reproduce

import qcodes as qc
from qcodes.dataset.sqlite_base import init_db, connect

dataDB = 'C:/Users/Junkie/Documents/Programming/Python/QCoDeS/datapool/experiments.db';
qc.config["core"]["db_location"] = dataDB;

conn = connect(dataDB, debug=True)
init_db(conn)

from qcodes.dataset.experiment_container import Experiment
from qcodes.dataset.measurements import Measurement
from qcodes import new_data_set, new_experiment

Expected behaviour

Use the database under the path dataDB for the storage of measurements..

Actual behaviour

It uses the database created under the current working directory instead.

[dmtvanzanten]

The file qcodes\dataset\experiment_container.py, host of new_data_set and new_experiment, contains the following line
DB = qcodes.config["core"]["db_location"].
As this is executed as soon as any part of qcodes is imported, the variable DB is set to the default config that is saved to the disk as part of the qcodes repository.
