All the code was there in btrfs::read_uuid() to read the UUID from the
btrfs-show command. It just needed enabling.
This is only relevant when: (1) the blkid command is unavailable as
GParted primarily reads the UUID through the FS_Info cache using the
blkid command, and (2) the btrfs command is unavailable and the btrfs
module uses the older btrfs-show command instead.
For active swap space read the usage from /proc/swaps. (Linux kernel
uses units of 1 KiB). By definition inactive swap space is 100% free.
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/sda2 partition 5242876 430552 -1
Always set fs.read = FS::EXTERNAL even if /proc/swaps doesn't exist so
that an attempt is made to open the file generating a specific error, in
addition to the generic error.
open("/proc/swaps", O_RDONLY): No such file or directory
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for linux-
swap file system support: util-linux.
Closes Bug #708107 - Usage of swap space is not reported
A "Force Cancel" button and proper cancel support was added to
GParted 0.15.0 with the following commit:
Add proper cancel support (#601239)
89de9a5026
Part of Bug #707070 - Update Help Manual with GPT flags, Force Cancel
button, etc.
Enable the text progress bar and percentage complete from the e2fsck
command. Looks like:
# e2fsck -f -y -v -C 0 /dev/sda8
e2fsck 1.41.12 (17-May-2010)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
test8: |========================================= / 73.6%
Note that e2fsck deliberately brackets the progress bar with control-A
and control-B characters when it detects that it is not being run from a
terminal so that logsave(8) can exclude the progress bar from being
written to a log file. As GParted doesn't run e2fsck via a pty it
receives these control characters. Ignore them.

Closes Bug #697662 - Do not hide the progress of the tools used
Remove the -P, no progress bar option, from the ntfsresize command.
This allows the command to display the %age complete on its output which
is displayed in the operation details dialog, updated in real time.

Currently the btrfs command outputs figures to 2 decimal places followed
by an SI multiplier, e.g. 1.00GB.
This patch to btrfs-progs has been included in the integration
repository and will likely be included in the official btrfs-progs
repository at some point. It changes btrfs-progs to use IEC
multipliers, e.g. 1.00GiB. In fact multipliers already aren't used for
figures less than 1024.
[PATCH] btrfs-progs: use IEC units for size
http://permalink.gmane.org/gmane.comp.file-systems.btrfs/26888https://patchwork.kernel.org/patch/2825841/
Make GParted capable of also accepting IEC prefix multipliers, just "B"
for bytes and no multiplier, as well as an optional space between the
number and multiplier. Therefore accept values like these:
1.00GB 1.00 GB
1.00GiB 1.00 GiB
1073741824B 1073741824 B
1073741824
Closes Bug #706914 - Prepare for btrfs tools using IEC prefix
multipliers
With recent btrfs-progs, GParted failed to format a btrfs file system
over the top of an existing one. Make btrfs failed with this error:
# mkfs.btrfs /dev/sdb1
...
/dev/sdb1 appears to contain an existing filesystem (btrfs).
Use the -f option to force overwrite.
With this commit to btrfs-progs on 2013-02-19, mkfs.btrfs checks for
existing file system signatures, including all mirror copies of btrfs
super blocks, before writing to the partition.
http://git.kernel.org/cgit/linux/kernel/git/mason/btrfs-progs.git/commit/?id=2a2d8e1962e8b6cda7b0a7584f6d2fb95d442cb6
btrfs-progs: require mkfs -f force option to overwrite filesystem or partition table
Make GParted clear all the mirror copies of the btrfs file system super
blocks as erase_filesystem_signatures() is intended to prevent detection
of old signatures. This also avoids having to determine if the -f
option to mkfs.btrfs is available before trying to use it.
Closes Bug #705426 - Formatting Existing BTRFS Partition as BTRFS Fails
Because mkfs.btrfs Is Not Run with "-f"
Unfortunately a regression was introduced with GParted 0.14.1 wherein
linux-swap grow and shrink operations were broken. This regression was
a direct result of the following commit:
Prevent file system grow when partition grow fails (#686668)
fd96328920
The regression did not result in an error in the GUI, but rather the
linux-swap file system was not "resized" to the correct partition size.
The logic error introduced with the above commit listed has now been
fixed.
BACKGROUND INFORMATION ON LINUX-SWAP RESIZING
Currently no command line tools are available for resizing linux-swap.
However, since linux-swap does not contain data in the usual sense, we
simulate resizing linux-swap by re-creating (maximizing to fill
partition) the linux-swap file system with the same UUID and volume
label. To work correctly, the linux-swap file system must be re-created
after the final partition resize action has occurred.
Closes Bug #706604 - Failure to properly grow or shrink linux-swap when
resizing
Under GNOME Shell a running instance of GParted was getting named
"Gpartedbin". Ultimately GNOME Shell [1] uses the WM_CLASS X Window
property [2], which GDK defaults from the executable name.
$ xprop WM_NAME WM_CLASS
(Click on running GParted window)
WM_NAME(STRING) = "/dev/sda - GParted"
WM_CLASS(STRING) = "gpartedbin", "Gpartedbin"
Set the Class name, second string of the WM_CLASS X Window property, to
"GParted". (This prevents the use of the '--class' GTK+/GDK common
command line option [3] to override the class name, but I expect nobody
ever uses the option. GNOME Terminal has the same limitation. It also
has the same change setting the Class name [4]).

Dosfstools >= 3.0.18, released June 2013, renamed the programs thus:
dosfslabel becomes fatlabel,
dosfsck becomes fsck.fat,
and mkdosfs becomes mkfs.fat.
Dosfstools creates symbolic links for the old names for backward
compatibility, but unfortunately the Debian dosfstools-3.0.22-1
(experimental) package doesn't include those symbolic links. This
causes create, check and read unmounted FAT16/32 file systems to not be
supported.
Make GParted look for the new names first and the old names second.
Closes Bug #704629 - Program name changes in dosfstools 3.0.18+ break
FAT16/32 support
The menu option to mount a partition containing a file system should
be the active tense because choosing the menu option will perform the
action.

If the gnome-doc-utils package isn't installed and you try to compile
GParted from git it will fail with this:
$ ./autogen.sh
/usr/bin/gnome-autogen.sh
Cannot find file: gnome-doc-utils.make
You need to install gnome-doc-utils
After installing the gnome-doc-utils package the same error will be
reported again unless you also update the locate database.
Instead query the full path to the gnome-doc-utils.make file from the
gnome-doc-utils' pkg-config metadata.
Closes Bug #702040 - very strange gnome-doc-utils check in gparted
Only one partition editing tool should be in use at any one point
in time. If more than one is in use concurrently, then data loss
might occur through operations on common partitions or partition
tables. As such, prevent multiple copies of GParted from running
at the same time.
With the beta release of Fedora 19, invoking gparted appears to
automatically mount partitions. The systemd daemon appears to be
performing the automounting. Hence use systemctl runtime mask to
prevent this automounting from occurring.
Bug #701676 - gparted doesn't inhibit systemd mounting, leading to
potential data loss
It was difficult to retrieve whether a filesystem's label can be set on reformat.
The read_label flag can't be used as it decides whether to use the logic in the filesystem class
rather than the fallback in GParted::set_device_partitions, to determine the label of a partition.
The create_with_label flag is NONE for file systems that we cannot format with a
label (or that we cannot format at all).
The value is usually EXTERNAL for file systems that we can format with a label.
The read-only functionality is unused and the readonly parameter is
always false in copy_filesystem() and copy_blocks() methods. This has
been the case since the copy simulation was dropped by commit:
b9b4b2e55d
Remove simulation pass ( read test ) on move
Include guards need to be unique within GParted code and all included
library header files.
http://en.wikipedia.org/wiki/Include_guard#Difficulties
Use this model for all include guards:
#ifndef GPARTED_FILE_NAME_H
#define GPARTED_FILE_NAME_H
...
#endif /* GPARTED_FILE_NAME_H */
Closes Bug #539297 - Make include guards unique
The minimum NTFS volume size supported by the ntfs-3g mkntfs command
is 1 MiB. Since 1 extra sector is required for the backup NTFS boot
sector, an NTFS partition must be at least 1 MiB plus 1 sector.
To demonstrate, create a 1 MiB unformatted partition using MiB
alignment (/dev/sdd1), and then try to format the partition as NTFS.
# mkntfs -Q -v -L "ntfs-test" /dev/sdd1
Device is too small (1023kiB). Minimum NTFS volume size is 1MiB.
For GParted this means a minimum NTFS partition size of 2 MiB since
the smallest unit in the GUI is MiB.
Bug #697848 - Failure to Create 1 MiB NTFS Partition
Place the size and noaction options before the device name when resizing
an NTFS file system to match the order documented in the manual page.
Example fixed command:
# ntfsresize -P --force --force -s 104857600 --no-action /dev/sda11
Ext[234] file systems were being shrunk 1 KiB too small. Ntfs and
reiserfs file systems were being shrunk 1 byte too small. The resultant
file systems were ending up 1 block smaller than they could have been.
This looks like an accidental leftover from when GParted use to:
1) Shrink the file system 1 cylinder too small
2) Shrink the partition
3) Grow the file system to fill the partition
Relevant commit:
d663c3c277
removed cylindersize buffering during resize from the filesystems
