Mike Fleetwood ea7bd0d419 Rename Dialog_Progress member variable to m_curr_op
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.

Mike Fleetwood edb3afac7b Write starting device overview information to saved details (#639176)
Writes the starting device overview information of all known devices to
the top of the saved details HTML.  This is so that hopefully we don't
need to additionally ask users for their disk layouts via 'fdisk -l',
'parted print' and 'lsblk' when the saved details file is provided.

Also moves the equals separators "==================" from below to
above each operation so the each section is separated.

Luca Bacci f252e677d4 Ensure icon sizes (#39)
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

Mike Fleetwood 454ac64d19 Pass message parameters by reference to 2 Partition methods (#788813)
Note that this almost certainly has no performance benefit what so ever
because the methods are implicitly defined as inline [1][2] and the
compiler will have simply inlined the method bodies thus avoiding having
to construct copies of the passed parameters.

Do this anyway as constant objects are typically passed by reference
[3].  Also C++'s std::vector::push_back() [4] takes a const reference
parameter so update the kind of equivalent push_back_message() to take
a const reference parameter too.

        A function defined entirely inside a class/struct/union

Luca Bacci 6aba93d8c0 Change Gtk::ProgressBar appearance by providing custom CSS (#7)
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.

Luca Bacci 892f5542a4 Work around Gtk3 Gtk-CRITICAL messages when closing some dialogs (#7)
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.

Luca Bacci 5fb58f8877 port-to-gtk3: Use Gdk::Cursor via Glib::RefPtr<> (#7)
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.

Mike Fleetwood b9d3638a12 Fix false usage figures for busy SWRAID members (#27)
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.

Closes #27 - GParted may report incorrect usage for SWRAID partitions
             instead of unknown

Luca Bacci c602170faa modern-gtk2: Delay construction of Gtk::TreeModel* objects (!17)
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.

[1] gtkmm: Gtk::TreeModelColumnRecord Class Reference
    https://developer.gnome.org/gtkmm/2.24/classGtk_1_1TreeModelColumnRecord.html#details

    "Neither TreeModel::ColumnRecord nor the TreeModelColumns contain
    any real data - they merely describe what C++ type is stored in
    which column of a TreeModel, and save you from having to repeat that
    type information in several places.

    Thus TreeModel::ColumnRecord can be made a singleton (as long as you
    make sure it's instantiated after Gtk::Main), even when creating
    multiple models from it.

Luca Bacci 5407e8346b modern-gtk2: Introduce OptionComboBox class (!17)
Gtk::OptionMenu is a combobox type widget that is constructed from a
Gtk::Menu rather than a Gtk::TreeModel.  However Gtk::OptionMenu was
deprecated in gtkmm 2.4.1.

In GParted the Gtk::OptionMenu widget is used for:
- partition alignment combobox
- partition type combobox
- file system combobox

While they consist only of text we cannot use Gtk::ComboBoxText because
it doesn't expose functionality in its interface to make items inactive.

Create OptionComboBox helper class that builds a combobox consisting of
only text items, much like Gtk::ComboBoxText, but has the added
functionality to set items as inactive.

Mike Fleetwood f8512506ae Prevent online resizing of file systems mounted read-only (#10)
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 ]

Mike Fleetwood c82883d6a7 Add and set read-only mount flag in the Partition object (#10)
Set the partition read-only mount flag at the same time as setting the
file system mount points.

Mike Fleetwood 441b39347a Add parsing of read-only mount option into mount maps (#10)
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.

Mike Fleetwood f4994a2b63 Add read-only flag to mounted file system entries (#10)
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.

Mike Fleetwood 9c35d91453 Refactor get_filesystem_object()
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).
    "

[3] std::map::find
    http://www.cplusplus.com/reference/map/map/find/

    "Searches the container for an element with a key equivalent to k
    and returns an iterator to it if found, otherwise it returns an
    iterator to map::end.

Mike Fleetwood d3ef32096a Re-assign UFS to be a basic supported file system (!13)
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.

Mike Fleetwood 9a66139eff Add "other" file system type (!13)
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.

Mike Fleetwood ba79ddaf72 Limit FILESYSTEM_MAP entries to supported and basic supported FSs (!13)
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.

Mike Fleetwood f61481f3ae Separate unknown file system type from unsupported actions (!13)
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.

Mike Fleetwood 03e89b1289 Add support for minix file system (!12)
Util-linux package, at least as far back as version 2.23.2 as found on
CentOS 7, provides the mkfs.minix and fsck.minix commands.  Also blkid
from the same package, recognises minix file systems.

Create version 3 file systems because MINIX 3 [1] is the only supported
version and that reportedly uses version 3 of the file system [2].

Mike Fleetwood fc167a71a3 Move enum CUSTOM_TEXT into FileSystem.h
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.
