GParted reports used figure of active swap space from 4 KiB upwards,
actually 1 page, where as 'swapon -s' reports figures from 0 upwards.
This is because GParted is counting the 1 page swap space overhead as
used space.
# sfdisk -s /dev/sdb1
262144
# mkswap /dev/sdb1
# swapon /dev/sdb1
# swapon -s
Filename Type Size Used Priority
/dev/sdb1 partition 262140 0 -1
For this case GParted reports used as 4 KiB.
(ptn size - swap size = 262144 - 262140 = 4)
Instead make GParted report used figure without any overhead from 0
upwards, matching what 'swapon -s' reports.
Bug 742647 - Swap usage doesn't match figures reported by swapon -s
GParted's internal block copy has an off by one sector bug when the
source is before the destination; and the copy is performed backwards
from high block to low block. It is as though the source and
destination partitions were both one sector earlier on the disk.
In ASCII art it it looks like this:
Initial layout: x<--SRC--><--DST-->
Actually wrote: x<--SRC--
Should have written: <--SRC-->
Affects moving partitions too.
This bug has existed since commit:
bd9e16f22f
Thread the internal copy algorithm (#685740)
Effectively the last sector of the partition is missed and one sector
before the start of the partition is corrupted. Most of the time file
systems don't get around to using the very last sector so didn't notice.
Bug 742920 - GParted internal copy is overstepping partition boundaries
With reiser4progs 1.0.7 and earlier mkfs specifically checks for Linux
kernel 2.5 or 2.6. On Linux 3.x it fails with the following warning:
# mkfs.reiser4 --yes --label "" /dev/sdb1
Warn : Linux 3.13.0-39-generic is detected. Reiser4 does not support
such a platform. Use -f to force over.
# echo $?
8
This is fixed in reiser4progs 1.0.8 and later. From the reiser4progs
SourceForce README.txt:
. Do not ask for confirmation to work under Linux-3.X;
Found on Ubuntu 12.04 LTS and Ubuntu 14.04 LTS both with reiser4progs
1.0.7 and a Linux 3.x kernel.
Fix by adding "--force" flag to the mkfs command line.

The GNOME Logo & Trademarks page
(http://www.gnome.org/logo-and-trademarks/) says:
* All the letters in "GNOME" should be capitalized.
Also correctly capitalise the program name as GNOME Partition Editor in
the Manual, and gparted.doap file (used in web git browser).
Bug 739805 - GNOME is incorrectly capitalised on the website and else

Split the resizing file system and resizing partition calls in
GParted_Core::resize() into separate grow and shrink code paths.
Note that this also changes the degenerative case of calling resize()
when the partition isn't changing size, for non-swap partitions, from a
file system check step to a successful no-op. This doesn't matter as my
testing never found resize() to be called when the partition isn't
changing size.
Also correct spelling of local variable success.
Bug 741211 - Remove unnecessary duplicate actions when resizing a
partition
Shrinking swap partition operation performs these steps:
Shrink /dev/sdb2 from 2.00 GiB to 1.00 GiB
+ calibrate /dev/sdb2
+ check file system on /dev/sdb2 for errors and (if possible) fix them
checking is not available for this file system
+ shrink file system
+ create new linux-swap file system
+ mkswap -L "test-swap" -U "bd381eba-5df7-42e2-8e0e-411e9701c995" /dev/sdb2
+ shrink partition from 2.00 GiB to 1.00 GiB
+ create new linux-swap file system
+ mkswap -L "test-swap" -U "bd381eba-5df7-42e2-8e0e-411e9701c995" /dev/sdb2
Resizing a linux-swap partition was partially special cased in
GParted_Core::resize(). Make it fully special cased so that it just
does the following steps. No more skipped file system checks or extra
resizing.
1) Resize partition,
2) Recreate linux-swap.
This existing call chain recreates the linux-swap:
GParted_Core::resize_filesystem()
linux_swap::resize()
A compound move and resize operation still performs unnecessary checks
and recreates of linux-swap, but less than before.
Bug 741211 - Remove unnecessary duplicate actions when resizing a
partition
Shrinking a partition performs a single file system check step, but
growing a partition still performs two file system checks.
Grow /dev/sda8 from 1.00 GiB to 10.00 GiB
+ calibrate /dev/sda8
+ check file system on /dev/sda8 for errors and (if possible) fix them
+ grow partition from 1.00 GiB to 10.00 GiB
+ check file system on /dev/sda8 for errors and (if possible) fix them
+ grow file system to fill the partition
This is a leftover from the early days of GParted when resizing a
partition used cylinder buffering and performed three file system
checks. See prior to commit:
d663c3c277
removed cylindersize buffering during resize from the filesystems.
Remove the second file system check when growing a partition.
Bug 741211 - Remove unnecessary duplicate actions when resizing a
partition
First use of PKG_CHECK_EXISTS causes additional checking messages to be
reported which splits the libparted version check message from it's
result, like this:
checking for libparted >= 1.7.1 (querying pkg-config)... checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
2.3
Call PKG_CHECK_EXISTS early, before first use to avoid this. Output
now looks like:
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
:
checking for libparted >= 1.7.1 (querying pkg-config)... 2.3
Bug 740004 - use pkg-config to check for version of libparted
Currently ./configure links and runs a program to query the libparted
library version, which is used to determine the availability of some
features. This makes cross-compiling harder because the compile host
has to fake a virtual installation target in which to run the check.
Because of this, pkg-config based Autoconf checks are preferred.
Switch to using a pkg-config based Autoconf check first to determine the
version of libparted, falling back to the previous method for older
distributions which don't provide a pkg-config file for libparted.
Also small comment tidy-up elsewhere.
Bug 740004 - use pkg-config to check for version of libparted
Simplify how the list of file system types is populated in the Create
New Partition dialog. Change from copying everything and removing
unwanted items to only copying required items. Makes the code simpler
and therefore easier to understand.
Only recognises ReFS file system. No other actions are supported.
Requires blkid from util-linux >= 2.24.
Bug #738471 - ReFS file system is not recognised
Use GParted_Core::supported_filesystem() to remove the need to
explicitly list the growing number of recognised, but otherwise
unsupported, file system signatures in multiple places.
Bug #738471 - ReFS file system is not recognised
Helper to check whether a recognised file system type is supported by
GParted or not. Supported means there is an implementation class and
will appear in the File System Support dialog.
Make supported_filesystem() a static member function so that it can be
called without a class object so that GParted_Core::GParted_Core()
initialiser isn't called multiple times. This requires FILESYSTEM_MAP
to become a static member variable too.
Bug #738471 - ReFS file system is not recognised
get_filesystem_object() takes a constant reference to a FILESYSTEM, but
FILESYSTEM is just an enumeration. So that's a pointer to a constant
int. Just pass by value instead.
RHEL / CentOS 5.6 and later officially support ext4 file system [1].
From RHEL / CentOS 5.3 ext4 file system was included as a technology
preview. Ext4 file system tools are in a separate package e4fsprogs,
using uniquely named commands. The standard e2fsprogs commands only
support ext2 and ext3 file systems.
# mkfs.ext4 /dev/sdb3
# tune2fs -l /dev/sdb3
tune2fs 1.39 (29-May-2006)
tune2fs: Filesystem has unsupported feature(s) while trying to open /dev/sdb3
Couldn't find valid filesystem superblock.
# echo $?

# tune4fs -l /dev/sdb3
tune4fs 1.41.12 (17-May-2010)
Filesystem volume name: <none>
Last mounted on: <not available>
Filesystem UUID: ba4a9d58-7728-4b47-8a90-80e772615637

Filesystem revision #: 1 (dynamic)
Filesystem features: has_journal ext_attr resize_inode dir_index filetype extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize

For ext4 only, search for the e4fsprogs specific commands first and the
standard e2fsprogs commands second.

Bug #738706 - GParted doesn't support ext4 on RHEL/CentOS 5.x
Automatic selection of the largest unallocated partition caused flashing
redraw of the partition graphic and partition list. Both the partition
graphic and partition list were being drawn blank then redrawn fully
populated. This only happened on some distributions including:
CentOS 5.10, 6.5, 7.0, Debian 6, Fedora 14, 20, Xubuntu 14.04 LTS. Did
not happen on: Kubuntu 12.04 LTS.
This is a workaround, not a complete fix. It moves automatic selection
of the largest unallocated partition to after processing of the GTK
Event loop in Refresh_Visual() which redraws the partition graphic and
partition list. These visuals are now drawn only once, fully populated,
however this draws them without the selected partition. The partition
selection is then drawn afterwards which causes the selection to flash
instead. This is significant improvement to the whole partition graphic
and partition list flashing when redrawn.
Bug #696149 - Double refresh of display introduced with default
unallocated space
The device combobox was getting drawn blank, then getting drawn again
with the selected device. This was happening because at the start of
Win_GParted::refresh_combo_devices() the GTK model behind the combobox,
liststore_devices, was cleared, changing the active item, causing the
combobox to get redrawn empty. After the GTK model had been repopulated
the active item was reset causing the comboxbox to get redrawn again,
now showing the selected device. Call flow:
Win_GParted::refresh_combo_devices()
liststore_devices->clear()
//Gtk::Combobox emits signal_change. Registered callbacks
//called.
Win_GParted::combo_devices_changed()
Win_GParted::Refresh_Visual()
...
...
combo_devices.set_active(current_device);
//Gtk::Combobox emits signal_change. Registered callbacks
//called.
Win_GParted::combo_devices_changed()
Win_GParted::Refresh_Visual()
...
This has always been the case, since the device combobox was first added
to GParted before version 0.1 by commit:
3a4b43e0ad
replaced deprecated OptionMenu with ComboBox ...
Fix by temporarily blocking the devices comboxbox from emitting
signal_changed while the GTK model behind the combobox is recreated.
However, since automatic selection of the largest free space was added
[1] in GParted 0.15.0, a more noticeable flashing redraw issue was
caused in which the partition graphic and partition list were both drawn
blank then redrawn fully populated. Some distributions were not
affected by this at all, some only experienced a single flash and others
suffered from two or more flashing redraws. Some affected
distributions: CentOS 5.10, 6.5, 7.0, Debian 6, Fedora 14, 19, 20,
Ubuntu 13.10, Xubuntu 14.04 LTS. Did not occur on Kubuntu 12.04 LTS.
