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
32-colour palette with HFS Plus using serene red outside that palette.
HFSPLUS - Serene Red
HFS - Red Hilight
LINUX_SWAP - Red Medium
LINUX_SUSPEND - Red Dark
- Red Shadow
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 Hilight (#D59FD4) - HFS
Magenta Medium (#B173B0) - HFSPLUS
Magenta Dark (#874986) - APFS
Magenta Shadow (#662C64) -
This commit just moves HFS and HFS Plus to their new magenta colours.
[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.

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.

Closes#23 - GParted doesn't detect APFS (Apple File system)
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.

No other file system allows this, but btrfs allows simultaneous mounting
with different read-write permission. Further, btrfs allows resizing
via read-write mounts, but not via read-only mounts.

Also with the above order of the read-only mount listed in /proc/mounts
first and the read-write mount second, GParted again allows a resize
operational to be tried, but if fails just like before:
Grow /dev/sdb1 from 512.00 MiB to 1.0 GiB (ERROR)
* calibrate /dev/sdb1 (SUCCESS)
* grow partition from 512.00 MiB to 1.00 GiB (SUCCESS)
* grow filesystem to fill the partition (ERROR)
* btrfs filesystem resize 1:max '/mnt/1' (ERROR)
Resize '/mnt/1 to '1:max'
ERROR: unable to resize '/mnt/1': Read-only file system
What happened is that the Mount_Info module only stores single read-only
flag against the mounted block device, not for each mount point, and as
the first and second sdb1 lines from /proc/mounts were processed, the
MountEntry became:
1st) mount_info[BS("/dev/sdb1")] -> {true , ["/mnt/1"]
2nd) mount_info[BS("/dev/sdb1")] -> {false, ["/mnt/1", "/mnt/2"]
So GParted thought the file system was mounted read-write, but used the
first mount point, /mnt/1, which was mounted read-only.
This is a very unusual situation so unlikely to be encountered by users.
Fix simply and safely by treating the mounted block device as mounted
read-only if any of the mount points are mounted read-only, rather than
just the last processed mount point.
Closes#10 - Gparted fails to resize btrfs partition that is mounted
read-only
Resizing a file system mounted read-only fails. Example:
# mkfs.btrfs /dev/sdb1
# mount -o ro /dev/sdb1 /mnt/1
In GParted try to resize partition sdb1. The operation fails like this:
Grow /dev/sdb1 from 512.00 MiB to 1.00 GiB (ERROR)
* calibrate /dev/sdb1 (SUCCESS)
* grow partition from 512.00 MiB to 1.00 GiB (SUCCESS)
* grow filesystem to fill the partition (ERROR)
* btrfs filesystem resize 1:max '/mnt/1' (ERROR)
Resize '/mnt/1' of '1:max'
ERROR: unable to resize '/mnt/1': Read-only file system
See GitLab issue for the testing results of attempting to online resize
all supporting file system while mounted read-only. No file system
allows online resizing while mounted read-only, except for reiserfs.
Issue #10 - Gparted fails to resize btrfs partition that is mounted
read-only
https://gitlab.gnome.org/GNOME/gparted/issues/10
Fix by preventing online resizing of *all* file systems mounted
read-only, including reiserfs. Instead of displaying the resize dialog
in this case, display an information dialog explaining why the partition
can't be resized. This is similar to what happens when attempting to
create a new partition on a disk without a partition table. The new
dialog looks like:
(!) Unable to resize read-only file system /dev/sdb1
The file system can not be resized while it is mounted read-only.
Either unmount the file system or remount it read-write.
[ OK ]
Closes#10 - Gparted fails to resize btrfs partition that is mounted
read-only
Set the partition read-only mount flag at the same time as setting the
file system mount points.
Closes#10 - Gparted fails to resize btrfs partition that is mounted
read-only
Parse file system mount options string from file and mount command
output, extracting the setting for the read-only flag and storing in the
mount maps. Read-only flag for swap space gets the struct MountEntry
constructor default of false.
Closes#10 - Gparted fails to resize btrfs partition that is mounted
read-only
Just updates the 2 maps in the Mount_Info module so that they also have
a read-only flag for each mount. Ensure that when a struct MountEntry
is created the readonly bool POD (Plain Old Data) type is initialised by
the constructor. Nothing yet sets or uses the flag.

Back when unallocated space handling was being added, this case was not
converted from open coding to using the provided method to check for
unknown file system usage. Specifically this commit missed using
Partition::sector_usage_known() in
Dialog_Base_Partition::prepare_new_partition():
7ebedc4bb3
Don't show intrinsic unallocated space (#499202)
Fix it now.
The function was using std::map::count() [1] to test if the file system
entry existed in the map before looking up the value using
std::map::operator[] to avoid having operator[] inserting elements which
don't exist [2].
Rewrite using std::map::find() [3] so that map is only searched once,
and so that it is more obvious what is happening without having to know
the subtleties of std::map::count() and ::operator[].
[1] std::map::count()
http://www.cplusplus.com/reference/map/map/count/
"Searches the container for elements with a key equivalent to k and
returns the number of matches.
Because all elements in a map container are unique, the function can
only return 1 (if the element is found) or zero (otherwise).
"
[2] std::map::operator[]
http://www.cplusplus.com/reference/map/map/operator[]/
"If k does not match the key of any element in the container, the
function inserts a new element with that key and returns a reference
to its mapped value. Notice that this always increases the
container size by one, even if no mapped value is assigned to the
element (the element is constructed using its default constructor).

There is no prospect of there being ufs-tools on Linux. The was a
project which did release ufs-tools version 0.1 in 2004, but has been
inactive since then.
http://ufs-linux.sourceforge.net/
Copying and moving is now implemented for file systems in the basic
supported category. Also mounting and unmounting of unsupported file
system and reporting their usage while mounted has been added. This is
all the support that GParted has ever implemented for UFS. Therefore
re-assign UFS as a basic supported file system as it looses no
functionality.
Closes!13 - Support copying and moving of unsupported partition content
For unsupported (including basic supported) file systems, also record
the mount point(s) when mounted and from /etc/fstab when not. This
allows mounted unsupported file systems to be unmounted and ones with
/etc/fstab entries to be mounted, just like fully supported file
systems.
Also for unsupported (again including basic supported) mounted file
systems query the kernel for the usage, just like is already done for
supported file systems.
Closes!13 - Support copying and moving of unsupported partition content
When previewing copying a partition of unknown file system usage into an
existing partition, the usage still shows that of the overwritten file
system. This affects existing supported file systems EXFAT, F2FS, MINIX
and UFS and the new basic supported one too, all for which GParted can't
read the file system usage.
Handle the case of the source file system usage being unknown and
explicitly set the copied usage to unknown too.
Closes!13 - Support copying and moving of unsupported partition content
GParted previews copying a partition of unknown file system usage into a
new partition as 100% used. This affects existing supported file
systems EXFAT, F2FS, MINIX and UFS and the new basic supported ones too,
all for which GParted can't read the file system usage.
When preparing the working new_partition object in the Copy / Paste
dialog, the maths for the known file system usage happened to convert
the figures of used = -1 and unused = -1 into set_sector_usage(-1, 0).
Those values passed to set_sector_usage() mean unable to query the file
system size so assume it fills the partition and unused is 0, hence 100%
used.
Fix this by specifically handling the copying of file systems with
unknown usage, setting the pasted file system usage to unknown too,
used = -1 and unused = -1.
Closes!13 - Support copying and moving of unsupported partition content
To display the supported actions for all basic supported file systems to
the users.
Prepare the list of file system actions in Win_GParted because calling
get_fs() for the "other" actions requires the gparted_core object and
load_filesystems() currently doesn't have access to it. One alternative
would have been to make get_fs() and FILESYSTEMS static members of
GParted_Core class. Another alternative would have been to pass the
gparted_core object to load_filesystems(). The chosen way seemed
simplest.
Closes!13 - Support copying and moving of unsupported partition content
Want a single term under which the supported actions for all basic
supported file systems are displayed in the File System Support dialog.
"Unknown" isn't the correct adjective because the group includes
unknown, but also includes: BitLocker, GRUB2 core image, ISO9660, Linux
SWRaid, Linux Suspend, REFS and ZFS. Add "other" file system type just
for displaying in the dialog.
Closes!13 - Support copying and moving of unsupported partition content
Introduce a third category of basic file system support to go along with
the existing full and none. Use the file system's entry in
FILESYSTEM_MAP to determine the level of support. See comment in
GParted_Core::init_filesystems() for details.
Add and remove FILESYSTEM_MAP NULL pointer entries as required, so that
only the file system types intended to have basic support have such
entries.
Closes!13 - Support copying and moving of unsupported partition content
PATCHSET OVERVIEW:
Forum user wanted to be able to move a partition with unknown content:
Topic: Can't move/rezise partition on android device (unknown format)
http://gparted-forum.surf4.info/viewtopic.php?id=17742
While GParted isn't going to be able to run any sort of file system
check on the unknown content there isn't any reason why such a partition
can't be copied or moved so long as the partition stays the same size.
GParted can just use it's existing internal block copy routine it uses
for copying and moving most partition content. This is no different to
a few of the already supported file system types which don't have a
check-repair tool: exfat, f2fs, nilfs2, udf, ufs.
This patchset introduces a third category called basic file system
support to go along with the existing full and unsupported categories.
Basic supported file systems will just use GParted's inbuilt
capabilities to perform actions so they won't need a derived FileSystem
implementation class. Unknown file systems along with all other
recognised, but otherwise unsupported, file systems will be assigned to
this new basic supported category.
THIS PATCH:
FS_UNKNOWN is used when GParted is unable to identify the contents of a
partition. FS_UNKNOWN is also used to generate a file system support
set with no supported actions, in the FileSystem::FS::FS() constructor
and in GParted_Core::get_fs().
As support for operations on partitions with unknown content is being
added, the second usage will be confusing or even wrong.
FS( FS_UNKNOWN ) constructs the no supported actions set, yet GParted
will support some actions for the FS_UNKNOWN file system type.
Therefore add FS_UNSUPPORTED for the second usage.
Closes!13 - Support copying and moving of unsupported partition content
The Open and Close pages use third person present tense for the "Choose:" paragraph. On the Close instruction, it had "closed" next to a "refreshes". So this commit simply applies present tense to "closed".
