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

Stop using deprecated widget alignment enumerators (#652044)
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.
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.

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.

Starting from Gtkmm3 Gdk::Cursor objects cannot be constructed directly,
but instead you have to get a smart pointer to an instance by calling
the static member function Gdk::Cursor::create().
Gdk::Cursor::create() returns a Glib::RefPtr<Gdk::Cursor> object.
Gtkmm3 always uses Glib::RefPtr<Gdk::Cursor> in its interface and never
plain Gdk::Cursor.

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.

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.

Resizing a file system mounted read-only fails. Example:
# mkfs.btrfs /dev/sdb1

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)

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.

the constructor. Nothing yet sets or uses the flag.

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[].

"Searches the container for elements with a key equivalent to k and

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
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 CUSTOM_TEXT enumeration is exclusively used as the type of one of
the parameters to the functions get_generic_text() and get_custom_text()
in the FileSystem class and derived classes. The definition of the
enumeration therefore belongs in FileSystem.h. Move it.
After a failed LUKS unlock attempt the password entry dialog shows the
error "Failed to open LUKS encryption". Improve the user experience by
clearing that error message at the start of the next attempt to avoid
contradictory information with the main windows status of "Opening

Bug 795617 - Implement opening and closing of LUKS mappings
The Change_UUID_Warning vectors were fat16 and ntfs class member
variables, but are only ever accessed in the get_custom_text() method.
Make them local variables in get_custom_text() instead. Static so that
references to them can be returned.
Same case as for FileSystem Label dialog before; the Partition Name
dialog only has a single line of just 2 widgets. Therefore switch to a
simpler horizontal box widget to lay them out.
The FileSystem Label dialog only has a single line of just 2 widgets; a

capable table to hold this. Switch to a simpler horizontal box widget.
Note that this change is not related to porting to Gtk 3 and stopping
using deprecated APIs because both HBox [1] and Table [2] are deprecated
in Gtk 3.2 and Gtk 3.4 and replaced by Box with horizontal orientation

Replace the insert() method (which reports an error when inserting a
password with a key which already exists) with the store() method which
replaces or inserts the password depending on whether the key already
exists or not respectively. There is also an optimisation that nothing
is changed if the password to be replaced is the same as the one already
stored. The code in Win_GParted::open_encrypted_partition() is
simplified now it doesn't have to implement this pattern of behaviour
itself.

Bug 795617 - Implement opening and closing of LUKS mappings
The underlying C coded Gtk Entry widget is careful to zero memory after
use, allowing the widget to be safely used for password entry [1].
However the C++ method Gtk::Entry::get_text() just takes the underlying
C string from the Gtk Entry widget and copies it when constructing a
Glib::ustring for the return value [2].
So directly use the Gtk/C API to get the C string instead.
[1] https://git.gnome.org/browse/gtk+/tree/gtk/gtkentrybuffer.c?h=3.22.28#n92
See function trash_area() which zeros memory and its use in
gtk_entry_buffer_normal_insert_text(),
gtk_entry_buffer_normal_delete_text() and
gtk_entry_buffer_finalize().

_WRAP_METHOD(Glib::ustring METHOD const, FUNC) is processed to:

}
https://git.gnome.org/browse/glibmm/tree/glib/glibmm/utility.h?h=2.46.1#n82
Glib::ustring convert_const_gchar_ptr_to_ustring(const char* str)
{
return (str) ? Glib::ustring(str) : Glib::ustring();
}
So Gtk::Entry::get_text() calls Glib::ustring() constructor which
copies the C string to create the Glib::ustring object returned.
Bug 795617 - Implement opening and closing of LUKS mappings
To keep password dialog open, just keep running it in a loop performing
LUKS mapping unlock attempts with the entered passphrase until it
succeeds or the dialog is cancelled or closed. This is the same model
that is already used for the File Support System dialog and how the
[Rescan For Supported Actions] button is implemented.
Also any error from attempting to open the LUKS mapping is no longer
displayed in a separate error dialog or at all. Will add some sort of
error reporting into the password entry dialog in a following commit.
Creates new method Win_GParted::open_encrypted_partition() which handles
the non UI parts of attempting to open an encrypted partition. Running
"cryptsetup luksOpen" and updating the stored passphrase as needed.
Bug 795617 - Implement opening and closing of LUKS mappings
Initial addition of a password entry dialog. Looks like:
+------------------------------------------------+
| LUKS Passphrase /dev/sdb1 |
+------------------------------------------------+
| Enter LUKS passphrase to open /dev/sdb1 |
| Passphrase: [ ] |
| |
| [ Cancel ] [ Unlock ] |
+------------------------------------------------+
A standard Gtk Dialog is used to accept the password once, with any
errors displayed in a separate error dialog afterwards. This is poor UI
design. A password dialog should remain open for all authentication
attempts and only close when successful or the dialog is cancelled or
closed. This UI design issue will be improved in following commits.
