Running GParted on AltLinux with dmraid installed but with no configured
RAID arrays produces this error:
# gparted
...
Could not stat device /dev/mapper/No RAID disks - No such file or directory.
Most distributions use dmraid 1.0.0.rc16 which reports no raid disks
like this:
# dmraid -sa -c
no raid disks
# echo $?
1
However AltLinux had the slightly older version, dmraid 1.0.0.rc14,
which reported no raid disks like this:
# dmraid -sa -c
No RAID disks
# echo $?
0
So because dmraid 1.0.0.rc14 reported success, exit status 0, and the
"No RAID disks" message was not in lower case, that text was considered
a disk device in a DMRaid array. Fix by checking for "no raid disks" in
any case.

Fix to make mkfs.f2fs properly handle labels longer than 16 characters
was included in f2fs-tools 1.2.0 [1]. The oldest supported
distributions now include this release:
Distro EOL f2fs-tools
- Debian 8 2020-Jun 1.4.0
- RHEL / CentOS 7 2024-Jun 1.4.1
- SLES 12 2027-Oct Unknown

Note that on Ubuntu 14.04 LTS blkid from util-linux 2.20.1 is too old to
recognise F2FS file systems, as 2.23 is required for F2FS support [2].
mkfs.f2fs claims the maximum label length is less than 512 characters,
but actually accepts 512 characters.

On CentOS 7 with f2fs-tools 1.4.1, checking an F2FS file system fails
like this:

Turns out that the '-y' option was not available until f2fs-tools 1.10.0
and is identical to the existing '-f' option anyway [1], which GParted
already uses. Just remove the '-y' option passed to fsck.f2fs.

Before this commit [1] first included in f2fs-tools 1.5.0, dump.f2fs
didn't report the total space used by the file system. This causes F2FS
file system usage not be reported on older distributions, including
RHEL/CentOS 7 and Debian 8.
On CentOS 7:
# rpm -q f2fs-tools
f2fs-tools-1.4.1-2.el7.nux.x86_64
# dump.f2fs -d 1 /dev/sdb3 | egrep 'sector size =|total.*sectors ='
Info: sector size = 512
Info: total sectors = 2097152 (in 512 bytes)
On Fedora 28:
# rpm -q f2fs-tools
f2f2-tools-1.10.0-1.fc28.x86_64
# dump.f2fs -d 1 /dev/sdb2 | egrep -a 'sector size =|total.*sectors ='
Info: sector size = 512
Info: total sectors = 3145728 (1536 MB)
Info: total FS sectors = 2621440 (1280 MB)
"total sectors" reports the size of the partition.
"total FS sectors" reports the size of the file system.
Cope with the file system size being missing. Pass -1 as the file
system size to partition.set_sector_usage() in this case. Note that
this means GParted won't be able to detect and report unallocated space
within the partition when using f2fs-tools < 1.5.0.

On Fedora 28 with f2fs-tools 1.10.0, dump.f2fs is producing NUL
characters in it's output and this completely breaks the parsing code in
f2fs::set_used_sectors(). Glib::Regex, as used by
Utils::regexp_label(), just doesn't match any text after the first NUL
character from the output.

Now that GParted requires Gtk3 there is no need to use floating point
numbers for compatibility with Gtk <= 2.22. Replace with symbolic

$ echo $?

Worst case scenario is that some how an old version of the btrfs command
is used which doesn't support the labelling functionality. Then this
commit would change GParted from disallowing labelling of a btrfs, to
allowing it, but presumably it would fail with an error from the btrfs
command reporting so. Arguably better from a support point of view.
Closes!26 - Remove support for btrfs-progs < 3.12
This commit [1] from btrfs-progs 3.12 removed the previously deprecated
programs btrfsctl and btrfs-show. As btrfs-progs 3.12 is now the
minimum requirement, remove support for those removed programs.
This commit is just removing the use of btrfs-show as a fallback to read
the label.
Note that 'btrfs-show /dev/PTN' didn't distinguish between a label of
"none" and no label. Hence the logic in btrfs::read_label() to do with
matching the label "none", or matching the label with or without single
quotes. Unfortunately as identified in this commit [2]
'btrfs filesystem show /dev/PTN' is subject to the same issue, but only
when the file system is mounted and only for btrfs-progs 3.12. This was
fixed by this commit [3] from btrfs-progs 3.14.

Closes!26 - Remove support for btrfs-progs < 3.12
PATCHSET OVERVIEW
The oldest supported distributions have these versions of the Linux
kernel and btrfs-progs:
Distro EOL kernel btrfs-progs
- RHEL / CentOS 7 2024-Jun 3.10.0 4.9.1
- Ubuntu 14.04 LTS 2019-Apr 4.4.0 3.12
- Debian 8 2020-Jun 3.16.0 3.17
- SLES 12 2027-Oct 3.12.28 3.16
Making the oldest supported packages be kernel 3.10 and btrfs-progs 3.12
allows the btrfs support code to be simplified by removing backward
compatibility.
THIS CHANGE
Remove old workaround for ignoring the error when resizing a btrfs to
the same size on Linux kernel < 3.2.
Also now that only exit status 0 is considered successful from btrfs
resize, the EXEC_CHECK_STATUS flag to execute_command() can be used,
rather than having to separately call set_status() afterwards.
Relevant commit history:
* 11d044dba0

The title has never been set in this case, and defaulted to the name of
the executable 'gpartedbin'. Fix this.
Closes#44 - Title not set in Resize/Move dialog for extended partitions
'launched' local POD (Plain Old Data) variable was left uninitialised,
but was set in both the try and catch clauses. Best practice is to
initialise when defined, so do that instead. Cosmetic change.
It is not creating a dialog (a pop-up window managed by GParted code
itself). It is launching independent yelp program to display the help,
so remove the "_dialog" from the name to avoid any possible confusion.
Originally, if the yelp command was not installed, attempting to display
help produced an error dialog with this message:
Failed to execute child process "yelp" (No such file or directory)
However since this commit during the Gtk 3 port [1] the error message
became this less useful one:
Operation not supported
Two attempts are made to display the GParted Manual, first using
gtk_show_uri() and second by executing the yelp command directly. Prior
to the aforementioned commit [1] both methods returned the failure
reason using the same 'error' variable. Hence reported the message
"Failed to execute child process "yelp" ..." from the second attempt.
However that commit had to re-code the second method as part of the Gtk
3 port and use a different error returning mechanism, thus the use of
different variable 'e'. But the dialog was left reporting the message
from the original 'error' variable, thus reporting "Operation not
supported" message from the first attempt using gtk_show_uri().
Fix by again displaying the message from the second failure into the
error dialog. Also make it very clear there are two error returning
variables by naming them 'error1' and 'error2_msg'.

port-to-gtk3: Use Gdk::AppLaunchContext to launch yelp (#7)
Use of PKG_NAME is deprecated in GNOME 3 and produced this warning:
$ ./autogen.sh
/usr/bin/gnome-autogen.sh
/usr/bin/yelp-build
***Warning*** PKG_NAME is deprecated, you may remove it from autogen.sh
...
Now that GParted is a GNOME 3 application with GNOME 3 yelp-tools
managed documentation this is redundant and can be removed. Previous
further analysis:
GNOME Bugzilla, Bug 743318, comment 18
https://bugzilla.gnome.org/show_bug.cgi?id=743318#c18
"
PKG_NAME is still used in GNOME 2.28's gnome-autogen.sh in error
messages. (GNOME 3's gnome-autogen.sh queries it from configure.ac
instead of requiring it to be set).
"
Also confirmed that it makes no difference by running ./autogen.sh with
and without PKG_NAME being set. The produced GParted build trees were
the same. Therefore the release and executable can't be affected.
GNOME 3's yelp doesn't use scrollkeeper or the OMF catalog, so the
constructed Makefile doesn't use xmllint to validate the scrollkeeper
DTD file. Therefore remove attempted sed edit of that line which no
longer exists in the Makefile.
Note that help/Makefile.am's @YELP_HELP_RULES@ automake macro expansion
comes from /usr/share/aclocal/yelp.m4 [1].

gparted-0.3.6 - code recreation from Source Forge
Looking at the SVN history this commit actually fleshed out the
implementations of fat16::get_label() and fat32::get_label() and added
the commented #includes:
https://sourceforge.net/p/gparted/svn/118
Added read label support for fat16 and fat32 using mtools mlabel command
2008-02-12
Then this SVN commit moved the mtools temporary file handling code into
Utils.cc, leaving behind the commented #includes:
https://sourceforge.net/p/gparted/svn/124
Added MTools temporary file handling functions
2008-02-19
Finally this commit removed fat32.cc by merging the code with fat16.cc:

Combine duplicate code for fat16/32
So remove the left behind commented #includes from fat16.cc.
A forum user had a case where they wanted to grow their in use root,
ext4 file system. GParted supports this, but the partition was a
logical partition inside an extended partition and GParted doesn't
support resizing an extended partition while any contained logical
partitions are busy.
Example layout:
Partition File System Mount Point
/dev/sdb1 ntfs
/dev/sdb2 [busy]
/dev/sdb5 [busy] ext4 /
unallocated unallocated
So just allow extended partitions to be resized online when online
partition resizing is available via libparted.
NOTE:
The block device that the Linux kernel provides for an extended
partition just maps to the first 1 KiB of the extended partition where
the Extended Boot Record is stored, and does not include any of the
contained logical partitions. Therefore no application can care that
the extended partition is resized while a logical partition is in use
because it can't use the extended partition block device to access any
data.
The on disk layout looks like this:

Closes!23 - Enable online resizing of extended partitions
With the Gtk3 port the File System Support dialog has become too wide
because the legend text is no longer wrapped. Set the max-width-chars
property to specify the natural size of the widget in terms of
characters [1]. It is converted to pixels using the average character
width in the current font.
Also use PACK_EXPAND_WIDGET when adding the label to the box so that if
the dialog is resized extra space is used to increase the size of this
child widget [2].

increasing the child widget size."

In Gtk2 the up and down buttons in a SpinButton were smaller leaving
space for 7 digits before scrolling the entry. In Gtk3 the up and down
buttons are much larger leaving only space for 4 digits. This occurs in
the SpinButtons in the Dialog_Base_Partition class as displayed in the
New Partition, Paste and Resize/Move dialogs.
Set width-chars property of all Gtk::SpinButtons to ensure 7 digits can
be displayed before scrolling the entry.

In Gtk3 the progress bar height is fixed and defined by the CSS theme in
use. Changing the widget allocation size does nothing, it is always
rendered the same way.
In many themes, including Adwaita, the progressbar is very, very thin.
Provide custom CSS to specify a height of 8 pixels.
The CSS source string has to be differentiated for Gtk pre and post
3.20, because Gtk 3.20 introduced some breaking changes in the way CSS
is handled.

The pulsebar looks very small and needs to be widened. The pulsebar is
packed inside the statusbar so that it displays activity text on the
left side and the pulsebar on the right side. Ideally we want the space
to be evenly divided for the textual messages and for the pulsebar
activity indicator.
For this we just have to set the 'homogeneous' property to TRUE for the
statusbar (note that GtkStatusBar inherits from GtkBox).
Also vertically align the pulsebar to the center of the statusbar. This
is achieved setting the 'valign' property to Gtk::ALIGN_CENTER for the
pulsebar widget.

There is a bug affecting Gtk+ 3.22.8 to 3.22.30 in which destroying a
GtkComboBox when it is not hidden results in this message:
Gtk-CRITICAL **: gtk_widget_is_drawable: assertion 'GTK_IS_WIDGET (widget)' failed
This happens in GParted when some dialogs are closed, for example the
Create New Partition and Create Partition Table dialogs. To work around
the issue we call Gtk::Dialog::hide() in the destructors of our dialog
classes.
The issue was fixed in Gtk 3.24.0.
* Gtk 3.22.8 was released in February 2017.
* Gtk 3.24.0 was released in September 2018.
