When the kernel version as stated in /proc/version did not have at least
three numbers separated by periods, the version would fail to be read.
Sample /proc/version to demonstrate problem:
Linux version 3.10-3-686-pae ...
The Linux kernel will always have a major number and a minor number
separated by a period. There is likely also a patch version number too
that would be preceded by a period. This enhancement will read 2 and 3
component Linux kernel versions.
GParted doesn't report extended partitions as busy if it contains only
busy LVM2 PV or SWRAID logical partitions. Libparted's
ped_partition_is_busy() only detects mounted file systems and swap space
as busy, not active LVM2 PVs or SWRAID members. This is as of libparted
3.1 and earlier.
Fix by determining the busy status of an extended partition based solely
on the busy status of the logical partitions it contains. This makes it
unnecessary to check for mounted DMRAID logical partitions or call
ped_partition_is_busy() for extended partitions.
Bug #712533 - Partitions not detected as busy inside Software RAID on
some distros
In this unusual setup of having one Linux Software RAID array
partitioned and a second array not partitioned, /dev/md1p1 partition in
the first array is falsely reported as busy when the file system filling
the second array /dev/md2 is mounted.
Partition RAID File System Mount mount
--------- ----------------- ---------------- -----------
/dev/sdb1 SWRAID /dev/md1
/dev/md1p1 ext4,Label=test1 (Unmounted)
/dev/sdb2 SWRAID /dev/md2 ext4,Label=test2 /mnt/2
This again affects Debian 6, Debian 7 and RHEL/CentOS 6.x and is as a
result of the this bug fixed in libparted 2.4:
http://git.savannah.gnu.org/cgit/parted.git/commit/?id=db52898c214310dab4ed84e6cb2f9ffc8c3aa502
linux: also detect "in-use" dmraid and scsi-Nth (N>=16) partition
Fix by not using libparted's ped_partition_is_busy() to determine if a
normal or logical partition is busy.
Bug #712533 - Partitions not detected as busy inside Software RAID on
some distros
On some distributions GParted doesn't detect when a file system is busy
and mounted when the partition is within a Linux Software RAID array.
Affected distributions include: Debian 6, Debian 7 and RHEL/CentOS 6.x.
This is because of a bug in libparted 2.3 and earlier. It was fixed by
this change in libparted 2.4:
http://git.savannah.gnu.org/cgit/parted.git/commit/?id=db52898c214310dab4ed84e6cb2f9ffc8c3aa502
linux: also detect "in-use" dmraid and scsi-Nth (N>=16) partition
Ubuntu 13.10 with libparted 2.3 is not affected because it contains a
distribution specific patch to correct it.
Fix by using GParted's internal mounted partitions map, mount_info, to
determine if a partition is busy, in addition to using libparted's
ped_partition_is_busy().
Bug #712533 - Partitions not detected as busy inside Software RAID on
some distros
Many file systems are capable of growing while mounted, and a few can
even shrink. This support must be explicitly enabled at configure time
with the --enable-online-resize flag and depends on a patched libparted.
Also requires kernel >= 3.6 for partition resizing, even if the
partition is in use (BLKPG_RESIZE_PARTITION).
Thanks to Mike Fleetwood for double check mark idea instead of a second
column to show the online grow/shrink.
Bug #694622 - Add support for online resize
In the Create New Partition dialog use ext4 as the default choice for
new file systems. It has been the preferred file system of
distributions for many years. Use ext3 and ext2 as second and third
choice defaults. This handles RHEL/CentOS 5.x which doesn't support
ext4.
Bug #711114 - Change default fs to ext4
Allow all partition warning messages to be selectable and copied. Merge
all the messages into a single Gtk::Label widget so that they can be
selected together.
Use a blank line between individual messages so that each message can be
distinguished. Therefore each message should be formatted as one or more
non-blank lines, with an optional trailing new line. This is true of
GParted internal messages and probably all external messages and errors
from libparted and executed commands too.
Bug #705596 - Partition Information Dialog - let user copy warnings
Applying operations or just scanning the partitions in GParted was
causing all stopped Linux Software RAID arrays to be automatically
started. This is not new with this patch set, but as a result of the
following behaviour which has existed for a long time. Chain of events
goes likes this:
1) Gparted calls commit_to_os() to update the kernel with the new
partition table;
2) Libparted calls ioctl() BLKPG_DEL_PARTITION on every partition to
delete every partition from the kernel. Succeeds on non-busy
partitions only;
3) Kernel emits udev partition remove event on every removed partition;
4) Libparted calls ioctl() BLKPG_ADD_PARTITION on every non-busy
partition to re-add the partition to the kernel;
5) Kernel emits udev partition add event on every added partition;
6) Udev rule:
SUBSYSTEM=="block", ACTION=="add", ENV{ID_FS_TYPE}=="linux_raid_member", \
RUN+="/sbin/mdadm -I $tempnode"
from either /lib/udef/rules.d/64-md-raid.rules or
.../65-md-incremental.rules incrementally starts the member in a
Linux Software RAID array.
Fix by temporarily adding blank override rules files which does nothing,
so that when the udev add and remove events for Linux Software RAID
array member partitions fire nothing is done; but only when required.
Note that really old versions of udev don't have rules to incrementally
start array members and some distributions comment out such rules.

Recognise in kernel, Linux Swap Suspend partitions. (When hibernated
the kernel write the RAM out to swap space and changes the magic string
from swap space to suspend). Recognition required either

Step 3 of 3:
Now that all label widgets are created with ALIGN_LEFT and ALIGN_CENTER
alignment remove the x_align and y_align parameters from mk_label() and
always use this alignment. Also specify this alignment via floats
rather than enumerators, one of which was deprecated.
Bug #652044 - uses deprecated APIs
Step 2 of 3:
ALIGN_RIGHT was only used for the size figures in the GParted > Devices
device selector with radio buttons. Change to ALIGN_LEFT and adjust the
widget packing to maintain appearance.
Bug #652044 - uses deprecated APIs
Gtkmm release 2.24 in February 2011 deprecated the use of these
alignment enumerators superseding them with:
Deprecated enumerator Use instead
Gtk::ALIGN_LEFT Gtk::ALIGN_START
Gtk::ALIGN_RIGHT Gtk::ALIGN_END
Gtk::ALIGN_TOP Gtk::ALIGN_START
Gtk::ALIGN_BOTTOM Gtk::ALIGN_END
gtkmm: gtkmm Enums and Flags [2.24]
https://developer.gnome.org/gtkmm/2.24/group__gtkmmEnums.html
The deprecated alignment enumerators were only used in the creation of
Gtk::Label widgets by method Utils::mk_label(). In all but three cases
the alignment was left, center. So make all labels with alignment left,
center and then stop using the deprecated enumerators.
Step 1 of 3:
ALIGN_TOP was only used for these 2 labels:
"Path:" text in View > Device Information;
"Path:" text in Partition > Information.
Use of ALIGN_TOP makes no difference to these labels so just change to
ALIGN_CENTER.

A mistake was made in the following commit:
Use systemctl runtime mask to prevent automounting (#701676)
4c109df9b5
The intention was to use 'systemctl list-units' rather than
'systemctl list-unit-files' so that auto-generated mount files would
also be masked and hence prevented from auto-mounting.
Now 'systemctl list-units' is used.

Bug #709276 - Percentage indicator for subcommand
Add concept of cursor position within the current line, separate from
the end of the buffer. This is so that programs which output a text
progress bar using backspace, such as resize2fs -p, are displayed
correctly.
Bug #709276 - Percentage indicator for subcommand
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.
