Name the structure member to 'fsname' used to store strings like "ext2"
etc. This is equivalent to what was previously done in this commit:

Previously made this change:

Now complete the renaming exercise of members and variables currently
named 'filesystem'.
Closes!52 - Rename members and variables currently named 'filesystem'
This is not strictly necessary as members are already recognised using
blkid since this commit earlier in the sequence "Recognise ATARAID
members (#75)". However it makes sure active members are recognised
even if blkid is not available and matches how file system detection
queries the SWRaid_Info module.
Closes#75 - Errors with GPT on RAID 0 ATARAID array
This matches how the array device is displayed as the mount point for
mdadm started ATARAID members by "Display array device as mount point of
mdadm started ATARAID members (#75)" earlier in this patchset.
Extend the DMRaid module member cache to save the array device name and
use as needed to display as the mount point.
Closes#75 - Errors with GPT on RAID 0 ATARAID array
Again this is to stop GParted allowing overwrite operations being
performed on an ATARAID member while the array is actively using the
member. This time for dmraid started arrays using the kernel DM (Device
Mapper) driver.
The DMRaid module already uses dmraid to report active array names:
# dmraid -sa -c
isw_ecccdhhiga_MyArray
To find active members in this array, (1) use udev to lookup the kernel
device name:
# udevadm info --query=name /dev/mapper/isw_ecccdhhiga_MyArray
dm-0
(2) list the member names exposed by the kernel DM driver through the
/sys file system.
# ls /sys/block/dm-0/slaves
sdc sdd
# ls -l /sys/block/dm-0/slaves

Closes#75 - Errors with GPT on RAID 0 ATARAID array
The previous commit, made mdadm recognised IMSM and DDF type ATARAID
members get displayed as "linux-raid" (Linux Software RAID array
member). This was because of query method 1 in detect_filesystems().
Fix this now by exposing and using the fstype of the member from the
SWRaid_Info cache.
Closes#75 - Errors with GPT on RAID 0 ATARAID array
Since mdadm release 3.0 (2009-06-02) [1] it has also supported external
metadata formats IMSM (Intel Matrix Storage Manager) and DDF, previously
only managed by dmraid.
A number of distributions have switched to use mdadm and kernel MD
(Multiple Devices) driver for managing these Firmware / BIOS / ATARAID
arrays. These include: Fedora >= 14 [2], RHEL / CentOS >= 6 [3],
SLES >= 12 [4], Ubuntu >= 16.04 LTS.
Therefore additionally parse members in these ATARAID arrays included in
mdadm output, and when activated using the kernel MD driver, in file
/proc/mdstat. Add fstype to the SWRaid_Info cache records to
distinguish members apart. So far the rest of the GParted code
continues to treat all members as FS_LINUX_SWRAID. This will be
resolved in following commits.
Note that this in no way affects how GParted shows and partitions the
array device itself, even those managed by dmraid and use the GParted
DMRaid module. It only affects how GParted shows the member drives
themselves.

Closes#75 - Errors with GPT on RAID 0 ATARAID array
PATCHSET OVERVIEW
A user had a Firmware / BIOS / ATARAID array of 2 devices configured as
a RAID 0 (stripe) set. On top of that was a GPT with the OS partitions.
GParted displays the following errors on initial load and subsequent
refresh:
Libparted Error
(-) Invalid argument during seek for read on /dev/sda
[ Retry ] [ Cancel ] [ Ignore ]
Libparted Error
(-) The backup GPT table is corrupt, but the
primary appears OK, so that will be used.
[ Ok ] [ Cancel ]
This is an Intel Software RAID array which stores metadata at the end of
each member device, and so the first 128 KiB stripe of the set is stored
in the first 128 KiB of the first member device /dev/sda which includes
the GPT for the whole RAID 0 device. Hence when libparted reads member
device /dev/sda it finds a GPT describing a block device twice it's
size and in results the above errors when trying to read the backup GPT.
A more dangerous scenario occurs when using 2 devices configured in an
Intel Software RAID 1 (mirrored) set with GPT on top. On refresh
GParted display this error for both members, /dev/sda and /dev/sdb:
Libparted Warning
/!\ Not all of the space available to /dev/sda appears to be used,
you can fix the GPT to use all of the space (an extra 9554
blocks) or continue with the current setting?
[ Fix ] [ Ignore ]
Selecting [Fix] gets libparted to re-write the backup GPT to the end of
the member device, overwriting the ISW metadata! Do that twice and both
copies of the metadata are gone!
Worked example of this more dangerous mirrored set case. Initial setup:
# dmraid -s
*** Group superset isw_caffbiaegi
--> Subset
name : isw_caffbiaegi_MyMirror
size : 16768000
stride : 128
type : mirror
status : ok
subsets: 0
devs : 2
spares : 0
# dmraid -r
/dev/sda: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0
/dev/sdb: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0
# wipefs /dev/sda
offset type
---------------------------------------------
0x200 gpt [partition table]
0x1fffffc00 isw_raid_member [raid]
Run GParted and click [Fix] on /dev/sda. Now the first member has gone:
# dmraid -s
*** Group superset isw_caffbiaegi
--> *Inconsistent* Subset
name : isw_caffbiaegi_MyMirror
size : 16768000
stride : 128
type : mirror
status : inconsistent
subsets: 0
devs : 1
spares : 0
# dmraid -r
/dev/sdb: isw, "isw_caffbiaegi", GROUP, ok, 16777214 sectors, data@ 0
# wipefs /dev/sda
offset type
---------------------------------------------
0x200 gpt [partition table]
Click [Fix] on /dev/sdb. Now all members of the array are gone:
# dmraid -s
no raid disks
# dmraid -r
no raid disks
# wipefs /dev/sdb
offset type
---------------------------------------------
0x200 gpt [partition table]
So GParted must not run libparted partition table scanning on the member
devices in ATARAID arrays. Only on the array device itself.
In terms of the UI GParted must show disks which are ATARAID members as
whole disk devices with ATARAID member content and detect array busy
status to avoid allowing active members from being overwritten while in
use.
THIS COMMIT
Recognise ATARAID member devices and display in GParted as whole device
"ataraid" file systems. Because they are recognised as whole device
content ("ataraid" file systems) this alone stops GParted running the
libparted partition table scanning and avoids the above errors.
The list of dmraid supported formats is matched by the signatures
recognised by blkid:

As they are all types of Firmware / BIOS / ATARAID arrays, report all
members as a single "ataraid" file system type. (Except for
"linux_raid_member" in the above blkid source listing which is Linux
Software RAID).
Closes#75 - Errors with GPT on RAID 0 ATARAID array
GParted_Core::FILESYSTEMS and ::FILESYSTEM_MAP and the methods that
query and manipulate them are self-contained. Therefore move them into
a separate SupportedFileSystems module.
Also having a single class maintaining all FileSystem interface objects
will make testing all the file system types much easier as there will be
no need to duplicate this functionality in the test.
Closes!49 - Add file system interface tests
To match the renaming performed as part of Bug 741424 "Add support for
GPT partition names". In particular this is most closely similar to:

After the previous commit the lp_device structure pointer parameter is
only used to provide sector_size. Just pass that instead.

GParted_Core::useable_device() doesn't change the pointed to PedDevice
structure. Pass it as const so the compiler enforces this.

The last distribution to include the separate 'udevinfo' command was
RHEL / CentOS 5 with udev 095. All supported distributions have much
newer versions of udev and instead have the 'udevadm' command.
A user reported that GParted was slow to refresh on FAT32 file systems:
"can take very long, up to several minutes; can be reproduced by running
dosfsck manually". This is because the file system was large and almost
full, and GParted performs a file system check just to to report the
file system usage.
Created a 4 GiB FAT32 file system and almost filled it with 4 KiB files,
just over 970,000 files.

Testing performance of the current fsck.fat:

8388608 sectors total

real 0m11.552s
user 0m2.183s
sys 0m7.547s
Free sectors in the file system according to fsck.fat:
(1046527 - 978846) * 4096 / 512 = 541448 sectors
Repeating this test while also using 'blktrace /dev/sdb2' and Ctrl-C
around the test in a separate terminal, reports these numbers of I/Os
being performed:
Read requests Read bytes
15,563 165 MiB
Prior to this commit [1] from 0.0.9, GParted used libparted's
ped_file_system_get_resize_constraint() to report the minimum size to
which a FAT* file system can be resized. Use this test program [2] to
performance test this method:
# time ./fscons /dev/sdb2
dev=/dev/sdb2
sector_size=512
min_size=7909522
max_size=8388608
real 0m2.673s
user 0m0.070s
sys 0m1.834s
Free sectors in the file system according to libparted
ped_file_system_get_resize_constraint():
8388608 - 7909522 = 479086 sectors
blktrace reports these numbers of I/Os being performed:
Read requests Read bytes
7,821 71 MiB
So using libparted resize constraint is a bit faster but is still
reading too much data and is really too slow. Also when testing GParted
using this libparted method against a corrupted FAT32 file system, on
every refresh, one popup dialog is displayed for each error libparted
detects with the file system, each of which needs acknowledgement.
Example popup:
Libparted Error
\DIRNAME\FILENAME.EXT is 107724k, but is has 1920
clusters (122880k).
[ Cancel ][ Ignore ]
There could be a huge number of such errors in a corrupted file system.
Not really suitable for use by GParted.
Test the performance of mtools' minfo command to report the file system
figures:
# time minfo -i /dev/sdb2 :: | \
> egrep 'sector size:|cluster size:|small size:|big size:|free clusters='
sector size: 512 bytes
cluster size: 8 sectors
small size: 0 sectors
big size: 8388608 sectors
free clusters=67681
real 0m0.013s
user 0m0.004s
sys 0m0.019s
Free sectors in the file system according to minfo:
67681 * 8 = 541448 sectors
blktrace reports these numbers of I/Os being performed by minfo:
Read requests Read bytes
1 16 KiB
This matches with minfo just reading information from the BPB (BIOS
Parameter Block) [3] from sector 0 and the FS Information Sector [4]
usually in sector 1. Note that the free cluster figure reported by
minfo comes from the FS Information Sector because it only reports it
for FAT32 file systems, not for FAT16 file systems. Scanning the File
Allocation Table (FAT) [5] to count free clusters is exactly what mdir,
without the '-f' (fast) flag, does. Test the performance of mdir:
# export MTOOLS_SKIP_CHECK=1
# time mdir -i /dev/sdb2 ::/ | fgrep 'bytes free'
277 221 376 bytes free
real 0m0.023s
user 0m0.011s
sys 0m0.023s
Free sectors in the file system according to mdir:
277221376 / 512 = 541448 sectors
blktrace reports these number of I/Os being performed by mdir:
Read requests Read bytes
5 448 KiB
So minfo and mdir together provide the needed information and are 2 to 3
orders of magnitude faster because they only read the needed BPB and FAT
data from the drive. Use these together to read the file system usage.

Bug 569921 - dosfsck -n delays device scan
Move snap_to_*() method calls from the point when all operations are
added to the list, to earlier when Resize/Move, Paste (into new) and
Create New dialogs are composing the new partition objects. In
particular for the Resize/Move operation, to just before updating the
file system usage.
This change finally resolves this bug.
Because of the dialog call chains into Dialog_Base_Partition,
snap_to_alignment() must be added into:
* Dialog_Base_Partition::prepare_new_partition() for the Resize/Move and
Paste (into new) dialogs; and
* Dialog_Partition_New::Get_New_Partition() for the Create New dialog.
Closes#48 - Error when moving locked LUKS-encrypted partition
The current device has to be passed to the dialog constructors and then
on to the Dialog_Base_Constructor. Note that the Dialog_Partition_New
constructor is already passed the current device, however it still needs
to pass it on to Dialog_Base_Constructor.
This is ready so that snap_to_*() methods can access the current device
when they are called from within these dialogs.

Closes#48 - Error when moving locked LUKS-encrypted partition
PATCHSET OVERVIEW
A user had 2 adjacent partitions which were aligned to multiples of
33553920 bytes (32 MiB - 512 bytes), not MiB or cylinders. As far as
GParted is concerned this is not aligned. The second partition
contained closed LUKS encrypted data. Recreate this setup with:
# truncate -s 200G /tmp/disk.img
# losetup -f --show /tmp/disk.img
/dev/loop0
# sfdisk -u S /dev/loop0 << EOF
65535 2162655 83
2228190 78904140 83
EOF
# partprobe /dev/loop0
# echo -n badpassword | cryptsetup luksFormat /dev/loop0p2 -
When trying to move the second LUKS encrypted partition to the right by
any amount, with the default MiB alignment, GParted displays this error
dialog and fails to even queue the operation:
Could not add this operation to the list
A partition with used sectors (78907392) greater than its
length (78905344) is not valid
[ OK ]
Overview of the steps involved:
1. The Resize/Move dialog composed a new partition to start a whole
multiple of MiB after the end of the previous non-aligned partition.
The new partition also had it's size increased to a whole multiple of
MiB, to 78907392 sectors (38529 MiB) which was 1.59 MiB larger than
before. Neither the start or end of the new partition are aligned at
this point.
2. Win_GParted::activate_resize() applied the change back to the closed
LUKS partition object, additionally making the used sectors equal to
the partition size.
(To match the fact that when opened the LUKS mapping it will
automatically fill the new larger partition size).
3. GParted_Core::snap_to_mebibyte() then aligned the partition start and
end to whole MiB boundaries, reducing the partition size in the
process to 78905344 (38528 MiB).
4. GParted_Core::snap_to_alignment() reported the error saying that it
couldn't add the operation to the list because it was invalid to have
the file system used sectors larger than the partition size.
Fix this by having the snap to alignment adjustments applied before the
dialogs update any associated file system usage. Specifically the
Resize/Move, Paste (into new) and Create New dialogs as these are the
only ones which either create or modify partition boundaries.
Validation done by snap_to_alignment() will continue to occur at the
current point when the operation is added to the list.
THIS COMMIT
snap_to_alignment() is doing two different jobs, it is (1) optionally
adjusting the new partition boundaries for MiB or Cylinder alignment;
and (2) checking that the partition boundaries and file system usage are
valid.
Split those into two different functions (1) snap_to_alignment() and
(2) valid_partition(). For now valid_partition() still calls
snap_to_alignment() so there is no functional change with this commit.
Closes#48 - Error when moving locked LUKS-encrypted partition
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.

Closes!25 - Modern Gtk3 - part 1
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:

repare-for-gtk3: Prepare for removal of Gtk::Widget::modify_fg() (#7)
[1] Gtkmm 3.0.1 NEWS file
https://gitlab.gnome.org/GNOME/gtkmm/blob/3.0.1/NEWS#L48
* RGBA replaces Color, though Color still exists because it is
used by TextView. We hope to deprecated Color completely in
gtkmm 3.2.
[2] Gtkmm 3.10.0 NEWS file
https://gitlab.gnome.org/GNOME/gtkmm/blob/3.10.0/NEWS#L127
Gdk:
* Deprecate Color.
Closes!25 - Modern Gtk3 - part 1
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.
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:

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
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.

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.

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
So that we might get more information from users when helping them.
Starting GParted from the command line now looks like this:
# ./gpartedbin
GParted 0.33.0-git
configuration --enable-online-resize
libparted 3.2
Closes!34 - Display more version and configuration information
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.
