4d57208add
Capabilities API returns NotImplementedError in case of SQLAlchemy driver. This issue is fixed in this patch by moving the function into the proper class. Another issue is, that get_capabilities function overwrites the DEFAULT_CAPABILITIES dict in base.py every time, when the function is invoked. This behavior was changed to create a CAPABILITIES dict in each DB driver's __init__ function by making a deep copy from DEFAULT_CAPABILITIES and updating the new dict with the AVAILABLE_CAPABILITIES. get_capabilities now returns the newly created CAPABILITIES dict without modifying it. Tests were also added to check that get_capabilities returns the expected values for each DB driver. Fixes-bug: #1292611 Change-Id: I725751b600bf462c19278e5785eb2d8530023083
