After an NTFS file system has been resized the command GParted currently
uses to read the file system usage fails like this:
# ntfsinfo --mft /dev/sdb1
Volume is scheduled for check.
Please boot into Windows TWICE, or use the 'force' option.
NOTE: If you had not scheduled check and last time accessed this volume
using ntfsmount and shutdown system properly, then init scripts in your
distribution are broken. Please report to your distribution developers
(NOT to us!) that init scripts kill ntfsmount or mount.ntfs-fuse during
shutdown instead of proper umount.
Failed to open '/dev/sdb1'.
Fix by added the '--force' flag as described in the error message.
Closes#57 - NTFS Resize results in Partition Information Warning on
Refresh
GParted uses ntfsinfo to read the NTFS file system usage. However when
ntfsinfo fails with a non-zero exit status GParted reports stdout twice,
rather than stdout and stderr. Correct this.
Closes#57 - NTFS Resize results in Partition Information Warning on
Refresh
With the same case as from the previous commit, the very long "Mounted
on ..." text is now wrapped, but the text may not be left justified.
Slowly adjust the dialog width and see how the text wrapping is updated
to fit the size adjustment but the text is centred rather than left
justified.
This is because setting the halign property to Gtk::ALIGN_START does not
guarantee left alignment of text for wrapped or ellipsized Gtk::Labels.
Use the xalign property instead.
To set the xalign property there is a method in the GtkMisc (Gtk::Misc)
base class:
gtk_misc_set_alignment (Gtk::Misc::set_alignment)
However, GtkMisc (Gtk::Misc) was deprecated in Gtk 3.14 (Gtkmm 3.14)
and in Gtk 3.16 (gtkmm 3.16) set_alignment() was replaced with the
introduction of two new methods:
gtk_label_set_xalign (Gtk::Label::set_xalign)
gtk_label_set_yalign (Gtk::Label::set_yalign)
Add a check for Gtkmm method Gtk::Label::set_xalign() in configure.ac
and use it when available.

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.

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.

Testing performance of ntfscluster, as used before this commit [1] from

Note that the clusters per volume figure reported by ntfscluster is

Testing performance using ntfsinfo:
# time ntfsinfo --mft /dev/sdb2 | \

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.
