The Operation classes contain partition objects which are copied by
value. Need to replace these with pointers to Partition objects instead
and manage their lifetimes so that they can be used polymorphically.
First step is to protect the partition members partition_new,
partition_original, and for OperationCopy class only, partition_copied
within the Operation classes and provide accessor methods.
get_partition_new() and get_partition_original() accessors are
implemented in the Operation base class so all derived classes get an
implementation. get_partition_new() is also virtual so that
OperationCheck and OperationDelete can override the implementation and
assert that they don't use partition_new. get_partition_copied() is
provided for the OperationCopy class only so can only be accessed via an
OperationCopy type variable.
Bug 759726 - Implement Partition object polymorphism
The apply_to_visual() method for the change UUID, format, label file
system and name partition operations duplicated identical code. This
code was just substituting the partition in the disk graphic vector with
the new partition recorded in the operation, as none of these operations
change the partition boundaries. Move this duplicate code into the
parent class in new method Operation::substitute_new().
Bug 755214 - Refactor operation merging
Win_GParted::Merge_Operations() method was modifying the internals of
Operation* objects; in particular the partition_new member variable.
This is breaking data hiding and encapsulation tenant of object oriented
programming.
Implement exactly the same operation merge semantics, but hide the
manipulation of the internals of the Operation* objects within the
Operation* classes themselves.
Bug 755214 - Refactor operation merging
When Operation objects are created they take a copy of the Device object
to which the operation is to be applied. The Device object includes a
vector of all the contained Partition objects currently on the device,
so these get copied too.
These additional deep copied Partition objects in the Operation object
are never accessed. Therefore don't copy the contained Partition
objects when copying the Device object into the Operation object.
Bug 750168 - Reduce the amount of copying of partition objects
This is part of parent bug:
Bug #721455 - Obsolete info in license text on multiple modules
and GNOME Goal:
https://wiki.gnome.org/Initiatives/GnomeGoals/Proposals
* verify all source files to make sure they have a license and a
copyright, and that both are up-to-date
Bug #721565 - License text contains obsolete FSF postal address
Restructure and word-smith translatable text associated with the
enhancement to add ability for setting UUID in an effort to better
align with the Gnome Documentation Style Guide.
See Bug #667278 - Add support for setting UUID
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.
Update the help manual to include this new functionality. Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.
This patch does not include setting the UUID on an NTFS file system.
