Btrfsctl and btrfs-show were depreciated in October 2011 and have been
superseeded by the newer btrfs multi-tool control command. Use btrfs as
first choice, falling back to btrfsctl and btrfs-show when not found.
There are still 2 issues with reading btrfs labels when falling back
on using btrfs-show command, rather than primary method of using the
blkid command:
1) Label is set no "none" when btrfs-show is reporting there is no
label, although it is impossible to distinguish from the case of the
label actually being set to "none".
2) The label has 2 trailing spaces appended as the regular expression
matches "Label: (btrfslabel )uuid:" rather than
"Label: (btrfslabel) uuid:" in the btrfs-show output.
Assume a label "none" means there is no label and fix the regular
expression.
Note that this enhancement changes GParted to first try the native
tools to determine the volume label for all file systems. If the
volume label is not found then the fall back method is to use blkid.
There is a small degradation in device refresh times as a result of
this change.
Closes Bug #662537 - Ext4 unicode labels not shown correctly
Fix bug introduced in GParted 0.9.0 in commit
4a8fef9822 to address ISO C++ ambiguity
compiler warning.
Due to the nature of the surrounding code, this bug was not evident
in the log file output.
Thanks to Magnus Fromreide for finding this bug.
When a new operation is added to operations list, check if a merge
is possible depending on the operation type:
OPERATION_RESIZE_MOVE: 2 consecutive "resize" operations on the
same partition
OPERATION_LABEL_PARTITION: 2 "label change" operations (need not be
consecutive) on the same partition
OPERATION_CHECK: 2 "check" operations (need not be
consecutive) on the same partition
OPERATION_FORMAT: 2 consecutive "format" operations on the
same partition
Closes Bug #438573 - Cancel out overlapping actions
Also fix a bug when copying partition using the Partition::Set(...)
method. This method did not initialize "sectors_used" and
"sectors_unused" members.
