Install exfatprogs into the CentOS 7 GitLab CI image, enabling unit
testing of GParted's use of exFAT programs. Exfatprogs is not yet
available for Ubuntu 20.04 as used in the Ubuntu GitLab CI image, only
for Ubuntu 20.10 so far.
Closes!30 - Add exFAT support
Libparted only allows selection of the partition type indirectly by
specifying the type of the file system it will contain [1] and so far
doesn't know about the exFAT file system. Therefore when GParted is
creating a new exFAT partition, it gets the GParted default of 83
(Linux file system) on MBR partition tables.
Example operation details:
Create Primary Partition #1 (exfat, 512.00 MiB) on /dev/sdb
* create empty partition
* clear old file system signatures in /dev/sdb1
* set partition type on /dev/sdb1
new partition type: ext2
* create new exfat file system
fdisk report:
# fdisk -l /dev/sdb
Disk /dev/sdb: 8 GiB, 8589934592 bytes, 16777216 sectors
Disk model: VBOX HARDDISK
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0xa2aab629
Device Boot Start End Sectors Size Id Type
/dev/sdb1 2048 1050623 1048576 512M 83 Linux
However the "exFAT file system specification" says:
https://docs.microsoft.com/en-us/windows/win32/fileio/exfat-specification
"10.2 Partition Tables
To ensure interoperability of exFAT volumes in a broad set of usage
scenarios, implementations should use partition type 07h for MBR
partitioned storage and partition GUID
{EBD0A0A2-B9E5-4433-87C0-68B6B72699C7} for GPT partitioned storage.
"
Fix this.

On Ubuntu the gparted shell wrapper still attempts to mask lots of
non-block device based file systems. Remove the --quiet option from the
systemctl --runtime mask command to see:

The gparted shell wrapper is currently looking for non-masked Systemd

also uses snap packages which are mounted file images via loop devices:

Fix by excluding:
1. Device name "/dev/fuse" because it's a character not a block device
and the mount point is associated with snap,
2. Device names starting "/dev/loop" and where the mount point starts
"/snap/" [1]. This is to allow for use of GParted with explicitly
named loop devices.

The gparted shell wrapper masks Systemd mount units to prevent it
automounting file systems while GParted is running [1], excluding
virtual file system which GParted isn't interested in [2]. The problem
is that there are a lot of virtual file systems and they have changed
between Fedora 19 and 33 so now the exclusion list is out of date.
Run GParted on Fedora 33 and query the mount units while it is running:
$ systemctl list-units -t mount --full --all

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
19 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.
So it masked these virtual file systems which didn't need to be masked:

Going back to first principles GParted cares that Systemd doesn't
automount file systems on block devices. So instead only mask mount
units which are on block devices. Where the 'What' property starts
"/dev/".
Systemd maintains hundreds of properties for each unit.
$ systemctl show boot.mount | wc -l
221
The properties of interest for all mount units can be queries like this:
$ systemctl show --all --property=What,Id,LoadState '*.mount'
...
What=sunrpc
Id=var-lib-nfs-rpc_pipefs.mount
LoadState=masked
What=/dev/sda1

[Unicode Black Circle character (U+25CF) replaced with star to avoid
making this this commit message Unicode.]
Currently the gparted shell wrapper lists the Systemd mount units and
takes the first space separated column as the unit name. If the LOAD
status of the unit is not "loaded" then Systemd prefixes the name with
an optional Black Circle. Prior to Systemd 246 these extra 2 characters
at the start of the line, including the optional Black Circle, were
suppressed by the --no-legend option, but with Systemd 246 this no
longer happens. As the mount unit names no longer start in the first
character of the line no units are masked. Instead the Unicode Black
Circle character, UTF-8 byte sequence E2 97 8F, is found at the start of
highlighted lines which results in this error:
Unit \xe2\x97\x8f.service does not exist, proceeding anyway.
Fix by adding the --plain option to suppress the optional Black Circle
in the systemctl output. Confirmed this option is available in the
oldest supported distributions with Systemd.
RedHat / CentOS 7 Systemd 219 systemctl has --plain option.
Ubuntu 16.04 LTS Systemd 229 systemctl has --plain option.

losetup uses /dev/loop-control [1][2] which no longer exists in the
Docker image. However even after creating /dev/loop-control in the

For now I have run out of ways to investigate and resolve this, so just

See how the test_BlockSpecial fixtures are getting major=0 and minor=0
for the block special devices they are testing with. This is happening
because there aren't any entries in /dev for those disks and partitions
listed in /proc/partitions. Assume that Docker in GNOME GitLab has
changed and that unneeded and unwanted devices in /dev are no longer
being created inside images.
In the test CI jobs execute new script, tests/makedev.sh, to create just
the first two block special devices mentioned in /proc/partitions needed
by test_BlockSpecial.

/dev entries
Seems to be referring to how Fill_Label_Device_Info() worked in the
past, but from history before the beginning of the GIT repository.
Remove out of date comment.
Debian user reported a bug [1] that when they had PS_FORMAT environment
variable set it prevented GParted running:
# export PS_FORMAT='ruser,uid,pid,ppid,pri,ni,%cpu,%mem,vsz,rss,stat,tty,start,time,command'
# gparted
The process gpartedbin is already running.
Only one gpartedbin process is permitted.
# echo $?
1
Using ps column 'command' includes the command and all it's arguments,
rather than just the command name as ps displays by default. Thus the
shell wrapper finds the grep command it's using when searching for the
gpartedbin executable.
# ps -e | grep gpartedbin
root 0 26114 14777 19 0 0.0 0.0 112712 940 S+ pts/0 10:42:02 00:00:00 grep --color=auto gpartedbin
Fix by searching for running processes using pidof. pgrep does regular
expression matching where as pidof checks program name is the same [2].
Therefore use of pidof is preferred over pgrep [3].

To better reflect that they represent the version of mke2fs executable
from the e2fsprogs package, even though the executable is called as
mkfs.ext4.

This earlier commit [1] from 2013 recognised the new names for programs
in dosfstools >= 3.0.18, specifically mkfs.fat and fsck.fat. Now that
the oldest supported distributions use dosfstools >= 3.0.18 it is no
longer necessary to support using the old names of mkdosfs and dosfsck,
so remove that code.
