7.1.0rc1

Features

• v = image_attribute.get_write_value() returns square sequences (arrays of arrays, or numpy objects) now instead of flat lists. Also for spectrum attributes a numpy is returned by default now instead.

• image_attribute.set_value(v) accepts numpy arrays now or square sequences instead of just flat lists. So, dim_x and dim_y are useless now. Also the numpy path is faster.

• new enum AttrSerialModel

• Attribute new methods: set(get)_attr_serial_model, set_change_event, set_archive_event, is_change_event, is_check_change_event, is_archive_criteria, is_check_archive_criteria, remove_configuration

• added support for numpy scalars in tango operations like write_attribute (ex: now a DEV_LONG attribute can receive a numpy.int32 argument in a write_attribute method call)

Bug fixes

• DeviceImpl.set_value for scalar attributes

• DeviceImpl.push_***_event

• server commands with DevVar***StringArray as parameter or as return type

• in windows,a bug in PyTango.Util prevented servers from starting up

• DeviceImpl.get_device_properties for string properties assigns only first character of string to object member instead of entire string

• added missing methods to Util

• exported SubDevDiag class

• error in read/events of attributes of type DevBoolean READ_WRITE

• error in automatic unsubscribe events of DeviceProxy when the object disapears (happens only on some compilers with some optimization flags)

• fix possible bug when comparing attribute names in DeviceProxy

• pretty print of DevFailed -> fix deprecation warning in python 2.6

• device class properties where not properly fetched when there is no property value defined

• memory leak when converting DevFailed exceptions from C++ to python

• python device server file without extension does not start
