All code implementing a step of an operation follows this pattern:
od.add_child(OperationDetail("Step heading"));
od.get_last_child().add_child(OperationDetail("More details"));
// Do step
success = ...
od.get_last_child().set_status(success ? STATUS_SUCCESS
: STATUS_ERROR);
At this point any libparted messages reported via exceptions need to be
added into the OperationDetail tree. Also adding further children into
the tree after collecting those errors needs to be prohibited (as much
as the previous patch prohibited it).
Add a new method which will replace the final set_status() call above
like this which set the status, captures the errors and flags that
further children shouldn't be added:
...
od.get_last_child().set_success_and_capture_errors(status);
It emits a callback to capture the errors to provide flexibility and so
that the OperationDetail class doesn't have to get into the details of
how GParted_Core saves libparted exception messages.
Bug 790842 - Report libparted messages into operation details at the
point at which they occur
