The backup super block is located at -1 MiB before the end of the
device, rounded down to the file system's bucket size [1], where the
bucket size is one of: 128 KiB, 256 KiB, 512 KiB, 1024 KiB [2].
location = device size - 1 MiB
= hex(1*1024*1024*1024 - 1*1024*1024)
= 0x3ff00000
Bcachefs magic is at byte offset 24 (0x18) into the super block [3].
The backup super block was not erased because GParted only writes zeros
from -512 KiB to the end of the device. It is necessary to clear old
signatures before formatting with a new file system to avoid confusion
from detection of multiple incompatible signatures [4][5]. Fix this by
writing zeros over all possible locations of the bcachefs backup super
block.

For bcachefs file systems 19 MiB and smaller, the available space is
reported as a very large value. The calculation went negative in a
64-bit signed value but then was interpreted as an unsiged value.
Writing any significant amount of data to the file system hangs.

Currently bcachefs-tools only provides a method to report the file
system usage while it is mounted. We won't make GParted mount a

Bcachefs [1] has many of the same capabilities as Btrfs [2] and ZFS [3]:
COW (Copy-on-Write), multi-device, multi-volume, snapshotting and many
more. Therefore when adding bcachefs use the same range of Orange
colours already used by Btrfs and ZFS [4]. As bcachefs is a native
Linux file system and ZFS is not, move ZFS to a darker shade of Orange
to allow bcachefs to be added in the middle:

Utils::trim_trailing_new_line() name is self-explanatory and doesn't
require a comment. The comment became superfluous with commit:
1fbc8988ff
Extract repeated code into trim_trailing_new_line() (!105)
Restricting the udev query from all types of device data to only
properties slightly simplifies the output from udevadm info which has to
be parsed. From this:
$ udevadm info --query=all --name=/dev/dm-0 | grep DM_NAME
E: DM_NAME=isw_cbaccqjiij_myarray
to:
$ udevadm info --query=property --name=/dev/dm-0 | grep DM_NAME
DM_NAME=isw_cbaccqjiij_myarray
Use if false return early pattern for the udevadm command found check.
Don't bother to check the exit status from running the udevadm command
or whether the output string contains anything before trying to parse it
for the serial number using Utils::regexp_label(). If the output string
is empty because either the udevadm command failed or the device has no
serial number then Utils::regexp_label() will assign the empty string to
serial_number; exactly what is wanted for these failure cases. This
makes the code simpler and easier to understand and still produces the
desired results in the failure cases.

Libparted treats USB keys as SCSI devices because they use the SCSI
major device number. This means the libparted device model string is
constructed from the kernel device driver vendor and model strings read
from /sys, stripped and separated by a space character [1]. Hence the
leading space in the libparted model string when vendor is blank.

A user reported that GParted was displaying binary data for the serial
number of their USB key. This was because hdparm -I was reporting
binary data for the serial number. It looked like this (except the
question marks were binary non-printable bytes).

Back in 2015 when reporting of drive serial numbers was being added
[1][2], using hdparm -I was the best option because it reported the
serial number of all hard drives including those in virtual machines,
worked the same everywhere and was available by default in most
distributions, but didn't work for USB keys. Where as lsblk -o SERIAL
was a new option not available yet on some distributions and didn't
report the serial number of drives in virtual machines.
Now hdparm -I capabilities are still the same; only working for hard
drives, including SSDs, but not USB keys. Except for the above case
hdparm has always found to not report serial numbers for USB keys, like
this:
# hdparm -I /dev/sde
/dev/sde:
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 15 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70 00 00 00

Now the lsblk -o SERIAL option is available on all distributions and
reports the serial numbers of all drives including for virtual machine
disks and USB keys.

lsblk gets it's information from udev. lsblk reports the SERIAL column
from the udev device property ID_SERIAL_SHORT, except when that is blank
it uses the ID_SERIAL property instead [3]. Note that ID_SERIAL is
composed from vendor and model information [4].

To only get the device serial number, or blank when not available, query
the udev ID_SERIAL_SHORT property directly using udevadm info rather
than using lsblk -o SERIAL. Previously GParted displayed "none" if
hdparm -I successfully found nothing, including for USB keys, and left
the serial number field blank on failure. Now the field will be blank
in both cases, no serial number and failure to query it.

This failure case must have been missed when exFAT support was first
added [1][2] because re-testing it now back on Fedora 33 does show the
error. Anyway fix this by just not attempting to read the file system
label or serial number in the file system specific methods while its
mounted. GParted will fall back to reading the label from the blkid
populated FS_Info cache. See
GParted_Core::set_partition_label_and_uuid() for details. The serial
number is already read from the cache first, falling back to the file
system specific method second.

when this is no longer required. It also results in simpler code as the
old shift bits style figures are converted into new direct multiplier
style figures. Therefore the final if statement checking all the
figures are set, computing and assigning partition usage remains simple
and unchanged.
Closes#261 - Unable to read the contents of exfat file system with
exfatprogs >= 1.2.3
exFAT file system usage is no longer readable when exfatprogs 1.2.3,
released 2024-05-23 [1], and later is installed. This is because the
output from dump.exfat changed as a result of commit [2].
On Fedora 39 with exfatprogs 1.2.3 installed and exfatprogs 1.2.2
compiled locally from git; old dump.exfat output:
# ~fedora/programming/c/exfatprogs/dump/dump.exfat /dev/sdb1 | egrep 'exfatprogs version|Volume Length\(sectors\):|Sector|Free Clusters:'
exfatprogs version : 1.2.2
Volume Length(sectors): 524288
>> Sector Size Bits: 9
>> Sector per Cluster bits: 3
Free Clusters: 65024
New dump.exfat output:
# dump.exfat /dev/sdb1 | egrep 'exfatprogs version|Volume Length\(sectors\):|Sector|Free Clusters:'
exfatprogs version : 1.2.3
Volume Length(sectors): 524288
>> Bytes per Sector: 512
>> Sectors per Cluster: 8
Free Clusters: 65024
Change the code to read exFAT usage only from dump.exfat 1.2.3 style
output. Don't parse older style output for now as that makes the code
simpler.

Network Block Devices are not displayed in GParted as partitionable
devices. They do appear in /proc/partitions, are reported by
fdisk -l [1] and by ped_device_probe_all() from libparted. Therefore
include them.
Create NBD device for testing:
# truncate -s 1G /tmp/disk-1G.img
# nbd-server -C /dev/null 9000 /tmp/disk-1G.img
# nbd-client localhost 9000 /dev/nbd0
After creating a couple of partitions for testing, the contents of
/proc/partitions looks like this:
# egrep 'name|nbd' /proc/partitions

Temporarily apply this patch to GParted so that it ignores the devices it
currently selects from /proc/partitions to use what get_device_probe_all()
reports. GParted shows NBDs.

This was also previously reported in the GParted Forum [1]. Future
Debian 13 ("trixie") and Ubuntu 24.04 LTS ("nobel") releases have moved
the needed gettext translation rules for .policy XML files:
/usr/share/gettext/its/policy.its
/usr/share/gettext/its/policy.loc
to new package libpolkit-gobject-1-dev not installed by default.
Document this new build time dependency.
Also see commits [2][3] where the equivalent change was needed in the
Alpine Linux and CentOS continuous integration images.

As the AppStream 1.0 [1] specification no longer describes them as
appdata files, but instead as metainfo files, rename the Makefile.am
variables for consistency with the name of the standard.
[1] AppStream 1.0
https://www.freedesktop.org/software/appstream/docs/index.htmlCloses#241 - Move appstream metadata out of legacy path
AppData files always were a subset of the AppStream specification
[1][2]. AppStream 0.12 specification [3] onwards says the metainfo
files will be found when placed in /usr/share/metainfo/ *AND* that
/usr/share/appdata/ is a legacy location *AND* a future release of
AppStream will likely drop support for it [4].
Debian 10, RHEL 7 and Ubuntu 18.04 LTS distributions all have the
/usr/share/metainfo/ directory containing application .appdata.xml and
.metainfo.xml files. Ubuntu 16.04 LTS does not have the directory
despite the AppStream specification [3] claiming it does. As old
supported distributions do have the directory, unconditionally update
this.
For reference are these commits in projects GNOME System Monitor [4] and
Evince [5] from 2017 making the same change.

"Rather than create a new schema from scratch, we'll be using a

Applications wishing to have long descriptions, screenshots and
other useful things are required to ship one or more files in

"2.1.2 Filesystem locations
Upstream projects can ship one or more metainfo files in
/usr/share/metainfo/%{id}.metainfo.xml, where id is a unique
identifier of this specific component.
(>) Note
Component metadata of type desktop-application as described in
Section 2.2, "Desktop Applications" can be installed with an
.appdata.xml extension as well for historical reasons. AppStream
implementations will read the XML files as long as they end up in
the right location on the filesystem.
(!) Important: Legacy Path
AppStream tools scan the /usr/share/appdata/ path for legacy
compatibility as well. It should not be used anymore by new
software though, even on older Linux distributions (like RHEL 7 and
Ubuntu 16.04 LTS) the metainfo path is well supported. Support for
the legacy path will likely be dropped completely with a future
AppStream 1.0 release.
