Create an active Linux Software RAID member which is larger than /dev
virtual file system and GParted will report the usage figure of the /dev
virtual file system for the SWRAID member.
# df -h /dev
Filesystem Size Used Avail Use% Mounted on
devtmpfs 732M 0 732M 0% /dev
# sgdisk -n 1:1M:+1G /dev/sdb
# mdadm --create --verbose /dev/md1 --level=linear --raid-devices=1 --force /dev/sdb1
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md1 started.
GParted reports the usage of /dev/sdb1 as:
Partition Mount Point Size Used Unused Unallocated
/dev/sdb1 /dev/md1 1.00GiB 0.00B 731.04MiB 292.96MiB
However GParted should have reported the usage as "---" for unknown
because it isn't coded to query the size of the SWRAID member within a
partition.
The fault has been bisected to this commit:
Extend un/mounting and usage reporting to unsupported file systems (!13)
95903efb1f
What happens for busy Linux Software RAID array members:
* GParted_Core::is_busy()
has custom code to identify busy members.
* GParted_Core::set_mountpoints()
has custom code to add the array device name as the "mount point" of
the member.
* GParted_Core::set_used_sectors()
falls into the else not a supported file system (because SWRAID
doesn't have a derived FileSystem implementation class).
* GParted_Core::mounted_set_used_sectors()
is called to get the file system usage of mounted, but unsupported
file systems, such as UFS and any others.
* Utils::get_mounted_filesystem_usage()
is called which queries the kernel using statvfs() and gets the file
system usage of the /dev virtual file system because the array
device name will always start /dev.
Fix by ensuring that GParted only asks the kernel for the usage of paths
which it knows are mount points of mounted file systems. (As read from
/proc/mounts and cached in the Mount_Info module). Also rename the
method, by inserting "_fs", to mounted_fs_set_used_sectors() to remind
us that it is for mounted *file systems* only.
Closes#27 - GParted may report incorrect usage for SWRAID partitions
instead of unknown

C++ initialises static member variables before main() is called.
Therefore the static members of:
struct Slots
{
static Gtk::TreeModelColumn<Glib::ustring> text;
static Gtk::TreeModelColumn<bool> sensitive;
private:
static Gtk::TreeModel::ColumnRecord record_;
};
are constructed before Gtk::Main() is called in main(). However the
Gtkmm documentation specifically says that they must be constructed
afterwards [1].
Resolve this by using the Construct On First Use Idiom [2] to delay
initialisation until the slots are first used. Normally this idiom uses
static local objects, however it is being applied to class static
objects here because the objects are accessed in many methods. The
downside of this approach is that the objects are never destructed,
which memory analysers like Valgrind could see as a memory leak, but
that is actually deliberate. That leak can be removed once we can use
C++11 and std::unique_ptr.
[1] gtkmm: Gtk::TreeModelColumnRecord Class Reference
https://developer.gnome.org/gtkmm/2.24/classGtk_1_1TreeModelColumnRecord.html#details
"Neither TreeModel::ColumnRecord nor the TreeModelColumns contain
any real data - they merely describe what C++ type is stored in
which column of a TreeModel, and save you from having to repeat that
type information in several places.
Thus TreeModel::ColumnRecord can be made a singleton (as long as you
make sure it's instantiated after Gtk::Main), even when creating
multiple models from it.

The shades of aquamarine, cyan and orange didn't fit with the GNOME
32-colour palette. Create a set of aquamarine, cyan and orange shades
which match the GNOME palette shades and update the colours of the
relevant file systems accordingly.
Aquamarine Hilight (#97DFC7) -
Aquamarine Medium (#70D2B1) - NTFS
Aquamarine Dark (#3EA281) - REFS
Aquamarine Shadow (#1F7258) -
Cyan Hilight (#95E3E5) - EXTENDED
Cyan Medium (#6FCECE) -
Cyan Dark (#3C9899) -
Cyan Shadow (#166F70) -
Orange Hilight (#E59F6A) -
Orange Medium (#E58749) - BTRFS
Orange Dark (#C26825) - ZFS
Orange Shadow (#984F18) -
Note that the hues of aquamarine and cyan are quite close and for the
thin outlines of partitions used in GParted they aren't easy to
distinguish. Hence also using different lightness to additionally
separate the colour for extended partitions from NTFS and ReFS file
systems.
Just add detection of APFS using GParted's internal magic string
detection. It just matches 1 byte of the 2 byte object type and the
4 byte magic field found in the super block [1]. See code comment for
more details.
Blkid has just gained recognition of APFS with util-linux v2.33 released
06-Nov-2018 [2].
This will write enough for GParted's simple internal detection to find
APFS:
# python -c '
import sys
sys.stdout.write("\0"*24 + "\1\0" + "\0"*6 + "NXSB")
' > /dev/sdb1

Currently Linux Swap, Linux Suspend, and HFS use reds from the GNOME

Apple have a new file system, APFS (Apple File System), which is a
successor to HFS Plus [1][2]. With HFS Plus using a colour outside the
GNOME 32-colour palette and there not being enough distinct reds
available for a new file system, create a new range of magenta colours
which fit with the GNOME palette and use them for the group of Apple
file systems.

Magenta Medium (#B173B0) - HFSPLUS
Magenta Dark (#874986) - APFS

[1] About Apple File System
https://developer.apple.com/documentation/foundation/file_system/about_apple_file_system
"Overview
Apple File System replaces HFS Plus as the default file system for
iOS 10.3 and later, and for macOS High Sierra and later. Apple File
System offers improved file system fundamentals as well as several
new features, including cloning, snapshots, space sharing, fast
directory sizing, atomic safe-save, and sparse files.

[2] Apple File System Reference
https://developer.apple.com/support/apple-file-system/Apple-File-System-Reference.pdf
"About Apple File System
Apple File System is the default file format used on Apple
platforms. Apple File System is the successor to HFS Plus, so some
aspects of its design intentionally follow HFS Plus to enable data
migration from HFS Plus to Apple File System. Other aspects of its
design address limitations with HFS Plus and enable features such as
cloning files, snapshots, encryption, and sharing free space between
volumes.

Update appdata file to be inline with the current AppStream
specification [1]. Start by running:
appstream-util upgrade gparted.appdata.xml.in
and then editing the appdata as wanted. Ensure that the file passes
validation:
appstream-util validate-relax --nonet gparted.appdata.xml.in
When Richard Hughes added the appdata file he licensed it under the
GFDL but assigned the copyright to Curtis Gedak [3]. Now change the
license to CC0-1.0 [4] as that is what most appdata files are licensed
under [5][6]. Curtis Gedak agrees to this by reviewing this change and
being the committer of this commit.
