Opening the Partition Information dialog for a file system mounted on a
very long mount point, or on openSUSE which mounts the OS from 10 btrfs
subvolumes from the same partition, will cause the dialog to be very
wide as the "Mounted on ..." text is not wrapped.
Back in Gtk2, when width_chars / max_width_chars were not set, wrapping
labels had a default width beyond which text wrapped onto a new line
[1].
For Gtk3 this default width was first reworked a bit [2], and then was
removed for the very early Gtk3 3.0.10 release [3].
It is recommended that applications explicitly set default values,
otherwise wrapping labels never wrap when requesting their natural
allocation.

Make sure not to base the minimum size on "max-width-chars", only
the natural size.

label: Don't try to guess a label's size
People should use window default sizes or label
width-chars/max-width-chars to find the ideal layout for a label
instead of relying on magic.
Closes!40 - Limit wrapping labels
Before Gtk 3.22 GtkScrolledWindow propagated natural size to its
Children and so on to descendants. In Gtk 3.22 this was changed to
always request the minimum size. This was done because it is believed
to be a safer default (gives a better behaviour) in case of dynamic
content inside the scrolled window, that is, content that may change
allocated size. [1][2][3]
When the scrolled window content is not dynamic the natural size is
preferable because it gives a better looking layout and without any
downside.
In the case of GParted content which is not dynamic, so request the
scrolled windows to allocate children at natural sizes for Gtk >= 3.22.
The benefits of natural size allocation are evident in presence of
wrapping labels (for example inside the "Partition Info" dialog), that
with the minimum size request likely end up taking a very small width.

GtkScrolledWindow: Make propagation of natural child sizes optional
0984d1622d
"Making propagation of child natural sizes mandatory (or default,
even) was evidently a mistake as this causes dynamic content in a
scrolled window to resize it's parent when the scrolled window is
competing for space with an adjacent widget."

The Gdk::RGBA data type was introduced to replace Gdk::Color in
Gtkmm 3.0 [1], with Gdk::Color being deprecated in Gtkmm 3.10 [2].
With this commit we make the change to Gdk::RGBA data type which is the
modern replacement to Gdk::Color. Gdk::RGBA can be used almost as a
drop in replacement because it keeps most of the Gdk::Color interface.
Also, this commit removes the C Gtk call introduced during the
port-to-gtk3 patchset by commit:

Mostly add, but also remove, #includes so both DialogFeatures.h and .cc
include exactly the header files each needs to get the definitions they
use.
Header file #include guards are there to specifically enable this.
To better reflect that it is loading the supported actions for one file
system into the treeview, just like it's parent load_filesystems() is
initiating the loading for all the file systems.
Select a partition and look at the available actions in the Partition
menu. Then add or remove some commands which that particular file
system uses and rescan to detect those changes. Open the Partition menu
again. It doesn't reflect the changes of supported actions seen in the
File System Support dialog. Select a different partition and then
select the original partition again. Now the available actions in the
Partition menu reflect the changes of supported actions.
Have been testing by adding and removing /sbin/e2label to add and
remove EXT2/3/4 file system labelling support just because that feature
has existed for a very long time and EXT2/3/4 are displayed near the top
of the File System Support dialog. Tested this minor issue existed as
far back as GParted 0.3.7.
Fix by simply also refreshing the valid operations to update the
Partition menu after updating the found file system specific commands.
Closes!38 - Fixes for minor issues with File System Support rescanning
Open the File System Support dialog, either add or remove some file
system specific commands used by GParted and press the
[Rescan For Supported Actions] button. The supported actions don't
change. However after just closing and reopening the dialog, the
supported actions do reflect the added or removed file system specific
commands.
Bisected to this commit:
4d6d464664
Display "other" in the File System Support dialog (!13)
The problem is that commit made a subset copy of the
GParted_Core::FILESYSTEMS vector, obtained from get_filesystems(), so
when the rescan ran and the FILESYSTEMS vector was updated with new
supported actions, the dialog still displayed the original subset copy,
so didn't reflect the changed supported actions.
Fix by passing a reference to the GParted_Core::FILESYSTEMS vector,
obtained from get_filesystems(), and perform the necessary filtering
inside the dialog, like before the above faulty commit. Additionally
finding and adding "other" file system to the end of the list.
Closes!38 - Fixes for minor issues with File System Support rescanning
The oldest supported distributions have these versions of ntfs-3g /
ntfsprogs.
Distro EOL ntfs-3g / ntfsprogs
- Debian 8 2020-Jun 2014.2.16AR.2
- RHEL / CentOS 7 2024-Jun 2017.3.23
- Ubuntu 14.04 LTS 2019-Apr 2013.1.13AR.1
The oldest version of ntfs-3g / ntfsprogs on Ubuntu 14.04 LTS includes
support for the --new-serial option.
$ ntfslabel -V
ntfslabel v2013.1.13AR.1 (libntfs-3g) - Display, or set, the label for an NTFS Volume.
$ ntfslabel --help | grep -- --new-serial
--new-serial Set a new serial number
Therefore it is no longer necessary to check for this option as it is
always available. The worst case scenario is that some how an old
version of ntfslabel is used which doesn't support this option. In such
a case GParted goes from not supporting changing the UUID to claiming
support, but presumably it would fail with an error reporting unknown
option when applied. Arguably better from an end user support point of
view.
A user reported GParted was slow to refresh and timing ntfsresize to
query his file systems found that it was taking 4.7 seconds and 9.2
seconds for sizes 31.7 GiB and 49 GiB NTFS file systems respectively.
Almost 14 seconds just to read the usage.
Created a 4 GiB NTFS and filled it with as many 4 KiB files as possible,
just over 800,000 files.

Computation of figures:

Free clusters = (4294963712 - 4294516736) / 4096 = 109.125
Testing performance of ntfscluster, as used before this commit [1] from
GParted 0.3 in 2006:
# time ntfscluster --force /dev/sdb2 | \
> egrep 'bytes per cluster|bytes per volume|clusters per volume|clusters of free space'
...
bytes per cluster : 4096

clusters per volume : 131071
clusters of free space : 110
real 0m4.243s
user 0m1.629s
sys 0m2.587s
Note that the clusters per volume figure reported by ntfscluster is
wrong. 4294963200 / 4096 = 1048575, not 131071.
Testing performance using ntfsinfo:
# time ntfsinfo --mft /dev/sdb2 | \
egrep 'Cluster Size|Volume Size in Clusters|Free Clusters'
Cluster Size: 4096
Volume Size in Clusters: 1048575
Free Clusters: 110 (0.0%)

Repeating the above tests while also using 'btrace /dev/sdb2' and Ctrl-C
around each test via a separate terminal, reports these numbers of I/Os
being performed:
Command Read requests Read bytes
- ntfsresize 2,695 1116 MiB
- ntfscluster 2,685 1116 MiB
- ntfsinfo 13 2208 KiB
No wonder that ntfsresize and ntfscluster take a long time, they read
just over 1 GiB of data from the 4 GiB file system, where as ntfsinfo
only reads just over 2 MiB.
Switch to using ntfsinfo to report file system usage.

With that same commit in parted 1.9 [1], libparted only recognised these
linux-swap names via deprecated aliases:

Again as GParted now requires libparted 2.2 or later:
1) Stop using alternative "linux-swap(new)" name as that is deprecated
by libparted.
2) Also stop using alternative "linux-swap(v1)" name as that code is
never used because libparted recognised the GParted "linux-swap"
name as a current alias.

Formatting a partition to cleared over the top of LVM2 PV leaves the

Having a member variable named 't' which is used to share state in a
Dialog_Progress object between on_signal_show() and on_cancel() methods
is horrible. Rename to something more meaningful.
Also initialise m_curr_op in the constructor's initialisation list,
rather than later when first used in on_signal_show(). Not strictly
required, but avoids this POD (Plain Old Data) member variable being
undefined in the Dialog_Progress object between construction and when
on_signal_show() previously assigned to it for the first time and
started using it.

Also moves the equals separators "==================" from below to

Some icon themes only provide large icons for stock items. This can
cause problems like overly large icons appearing in the GParted UI.
Found on Kubuntu 16.04 LTS with default breeze icon theme.
Be compatible with these icon themes by forcing scaling of stock icons
to the requested size.
Icons are used either by Gtk::Image widgets, or Gtk::CellRendererPixbuf
objects for comboboxes/treeviews. For Gtk::Image widgets we add
Utils::mk_image() that constructs Gtk::Image widgets and then sets the
pixel-size property. For Gtk::CellRendererPixbuf we add
Utils::mk_pixbuf() that first loads a Gdk::Pixbuf and then scales if
needed.
Closes#39 - After GTK3 port icons are too big on KDE
