Busy file systems are accessed via a mount point, LVM Physical Volumes
are activated via the Volume Group name and busy SWRaid members are
accessed via the array device, /dev entry. Therefore choose to show the
array device in the mount point field for busy SWRaid members.
The kernel device name for an SWRaid array (without leading "/dev/") is
the same as used in /proc/mdstat and /proc/partitions. Therefore the
array device (with leading "/dev/") displayed in GParted will match
between the mount point for busy SWRaid members and the array itself as
used in the device combo box.

Bug 756829 - SWRaid member detection enhancements
In cases where blkid wrongly reports a file system instead of an SWRaid
member (sometimes confused by metadata 0.90/1.0 mirror array or old
version not recognising SWRaid members), the UUID and label are
obviously wrong too. Therefore have to use the UUID and label returned
by the mdadm query command and never anything reported by blkid or any
file system specific command.
Example of blkid reporting the wrong type, UUID and label for /dev/sda1
and the correct values for /dev/sdb1:
# blkid | egrep 'sd[ab]1'
/dev/sda1: UUID="10ab5f7d-7d8a-4171-8b6a-5e973b402501" TYPE="ext4" LABEL="chimney-boot"
/dev/sdb1: UUID="15224a42-c25b-bcd9-15db-60004e5fe53a" UUID_SUB="0a095e45-9360-1b17-0ad1-1fe369e22b98" LABEL="chimney:1" TYPE="linux_raid_member"
# mdadm -E -s -v

...
NOTES:
* In mdadm terminology the label is called the array name, hence name=
parameter for array md/1 in the above output.
* Metadata 0.90 arrays don't support naming, hence the missing name=
parameter for array md127 in the above output.
Bug 756829 - SWRaid member detection enhancements
Add active attribute to the cache of SWRaid members. Move parsing of
/proc/mdstat to discover busy SWRaid members into the cache loading
code. New parsing code is a little different because it is finding all
members of active arrays rather than determining if a specific member is
active.
Bug 756829 - SWRaid member detection enhancements
Detection of Linux SWRaid members currently fails in a number of cases:
1) Arrays which use metadata type 0.90 or 1.0 store the super block at
the end of the partition. So file system signatures in at least
linear and mirrored arrays occur at the same offsets in the
underlying partitions. As libparted only recognises file systems
this is what is detected, rather than an SWRaid member.
# mdadm -E -s -v
ARRAY /dev/md/1 level=raid1 metadata=1.0 num-devices=2 UUID=15224a42:c25bbcd9:15db6000:4e5fe53a name=chimney:1

2) Again with metadata type 0.90 or 1.0 arrays blkid may report the
contained file system instead of an SWRaid member. Have a single
example of this configuration with a mirrored array containing the
/boot file system. Blkid reports one member as ext4 and the other as
SWRaid!
# blkid | egrep 'sd[ab]1'
/dev/sda1: UUID="10ab5f7d-7d8a-4171-8b6a-5e973b402501" TYPE="ext4" LABEL="chimney-boot"
/dev/sdb1: UUID="15224a42-c25b-bcd9-15db-60004e5fe53a" UUID_SUB="0a095e45-9360-1b17-0ad1-1fe369e22b98" LABEL="chimney:1" TYPE="linux_raid_member"
Bypassing the blkid cache gets the correct result.
# blkid -c /dev/null /dev/sda1
/dev/sda1: UUID="15224a42-c25b-bcd9-15db-60004e5fe53a" UUID_SUB="d0460f90-d11a-e80a-ee1c-3d104dae7e5d" LABEL="chimney:1" TYPE="linux_raid_member"
However this can't be used because if a user has a floppy configured
in the BIOS but no floppy attached, GParted will wait for minutes as
the kernel tries to access non-existent hardware on behalf of the
blkid query. See commit:
18f863151c
Fix long scan problem when BIOS floppy setting incorrect
3) Old versions of blkid don't recognise SWRaid members at all so always
report the file system when found. Occurs with blkid v1.0 on
RedHat / CentOS 5.
The only way I can see how to fix all these cases is to use the mdadm
command to query the configured arrays. Then use this information for
first choice when detecting partition content, making the order: SWRaid
members, libparted, blkid and internal.
GParted shell wrapper already creates temporary blank udev rules to
prevent Linux Software RAID arrays being automatically started when
GParted refreshes its device information[1]. However an administrator
could manually stop or start arrays or change their configuration
between refreshes so GParted must load this information every refresh.
On my desktop with 4 internal hard drives and 3 testing Linux Software
RAID arrays, running mdadm adds between 0.20 and 0.30 seconds to the
device refresh time.

Bug 756829 - SWRaid member detection enhancements
When multiple devices are named on the command line and (after sorting
and removing duplicates) the device following a non-existent or invalid
one is not checked for usability [1]. In most situations this isn't
noticed as the device gets skipped at the "Searching ... partitions"
step instead. However as seen in bug 755495 and commit [2]
checking usability matters.
For example (on CentOS 6.5) a large sector disk device can be edited
when it follows a non-existent or invalid device named on the command
line:
# modprobe scsi_debug dev_size_mb=128 sector_size=4096
# fgrep scsi_debug /sys/block/*/device/model

A non-existent or invalid disk device named on the command line caused
two libparted dialogs to be displayed repeatedly on every refresh. This
was because the device was only removed from the 'device_paths' vector
when it wasn't usable [1]; not when it didn't exist or was invalid, when
the libparted ped_device_get() call failed. Fix this.

Bug 755495 - GParted allowing partitioning of large sector devices
specified on the command line, when built with old
libparted which doesn't support it
When probing for disk devices GParted ensures that libparted is capable
of handling the sector size safely and that it is a real disk before it
is shown in the UI. However when disk devices are named on the command
line none of these checks are performed.
Libparted versions before v2.2 can only safely handle a sector size of
512 bytes. Therefore on old distributions with libparted < v2.2 GParted
allows unsafe editing of disk devices with larger sector sizes when they
are named on the command line. Known to affect these distributions:
RedHat/CentOS 5 (parted 1.8.1)
RedHat/CentOS 6 (parted 2.1)
For example (on CentOS 6.5) large sector disk device is ignored when
probing:
# modprobe scsi_debug dev_size_mb=128 sector_size=4096
# fgrep scsi_debug /sys/block/*/device/model
/sys/block/sdd/device/model:scsi_debug

Bug 756035 - GParted does not compile with newer gtkmm libraries in
Fedora 23
Glibmm 2.45.40 and later uses features in the ISO C++ 2011 standard.
The NEWS file [1] says:
Changes in 2.46 compared to 2.44:
General:
* Use, and require C++11, using features such as move operations,
noexcept auto, = delete, nulltpr, override.

Also found this by Murray Cumming [2]:
glibmm 2.45.40 requires C++11, both for its own build and by any
apps that use it. gtkmm also now requires C++11.
I think you are seeing a symptom of building the application without

you'd be better of using an m4 macro such as
AX_CXX_COMPILE_STDCXX_11().
Without enabling C++11 compiler features, compilation of GParted with

Bug 755608 - Labeling fat16/fat32 partitions hangs if certain

GParted waits forever when attempting to set a FAT16/32 file system
label which contains prohibited characters [1][2]. This is because
mlabel asks a question and is waiting for input. Force cancelling the
operation doesn't work either as GParted sends signal 2 (interrupt i.e.
[Ctrl-C]) but mtools commands specifically ignores this and a number of
other signals. Have to kill mlabel with signal 9 (kill) to regain
control of GParted.
Mlabel command with prohibited characters in the label:
# export MTOOLS_SKIP_CHECK=1
# mlabel ::"MYLABEL/ " -i /dev/sdb10

This is the equivalent case fixed in the earlier commit, but now using
copy/paste to create the second new partition rather than plain new.
Fix visually re-apply create operation in create-create-grow-first
sequence (#755214)
Start with an existing partition as a copy source. Then this sequence
of operations will cause the copy partition to disappear from the disk
graphic:
1) create new #1,
2) copy existing / paste into unallocated leaving space preceding,
3) resize new #1 larger.
There are two different types of copy operation. The first is copy into
unallocated space creating a new partition which needs treating the same
as create new operation. The second is copy into existing partition
which needs treating the same as the other operations which don't change
the boundaries of the partition. Fix apply_to_visual() accordingly.
Bug 755214 - Refactor operation merging
Move the code from OperationCreate::apply_to_visual() into new method
Operation::insert_new() in the parent class. This is in preparation for
the following commit.
Bug 755214 - Refactor operation merging
The apply_to_visual() method for the change UUID, format, label file
system and name partition operations duplicated identical code. This
code was just substituting the partition in the disk graphic vector with
the new partition recorded in the operation, as none of these operations
change the partition boundaries. Move this duplicate code into the
parent class in new method Operation::substitute_new().
Bug 755214 - Refactor operation merging
After previous commit "Replace open coded merge of resize/move into
create operation (#755214)" the second created partition would disappear
from the disk graphic in the following sequence: create new #1, create
new #2 leaving space preceding, resize #1 larger. The create new #2
operation still existed and was shown in the operation list. It was
just that it disappeared from the disk graphic.
Remember that when each operation is created it records the partition,
or the unallocated space, to which the operation is applied at the time
the operation is created in the partition_original member variable. In
the above sequence the resize #1 larger operation was merged back into
the create new #1 operation. When visually re-applying the create
new #1 operation to the disk graphic, it left a smaller unallocated
partition following it. This was smaller than the unallocated partition
recorded in the create new #2 operation, hence it failed to visually
re-apply to the disk graphic.
The insight to fix this is that it doesn't matter what size the
unallocated space was when the create new operation was constructed. It
only matters that the new partition to be created fits in the available
unallocated space currently in the disk graphic.
Bug 755214 - Refactor operation merging
This information is already documented in the existing comments
associated with the calls to merge_operations() and assignments to the
mergetype variables. The table just summaries the rules together in one
place.
Bug 755214 - Refactor operation merging
For the case of resizing/moving a new, not yet created partition,
activate_resize() open coded the merge operation. Again this code has
existed in GParted since before version 0.0.5 and the current code
history in Git.
Replace the necessary code so that an explicit merge_operations() call
is used instead; along with the other case of resizing/moving an
existing partition.
NOTES:
This commit changes the merge direction. The old coded merged forward
by removing the old create operation and adding a new create operation
with the new size. This was bad because with multiple pending create
operations, each merged resize operation reordered those create
operations. Then when the operations were applied the partitions were
created and therefore numbered in a different order to that shown in
disk graphic.
The new code merges backwards by updating the initial create operation
with the new size. This maintains the create operation order so that
when applied the partitions are numbered in the same order as shown in
the disk graphic.
Bug 755214 - Refactor operation merging
For the case of formatting a new, not yet created partition,
activate_format() open coded the merge operation. This code has existed
in GParted since before version 0.0.5 and the current code history in
Git.
Replace the necessary code so that an explicit merge_operations() call
is used instead; along with the other case of formatting an existing
partition.
Bug 755214 - Refactor operation merging
Creation of the various operations involved various implicit rules about
how the different types of operations were merged in different cases.
This was open coded in each ::activate_*() method. Abstract this into
new merge_operations() method and make the merging rules explicitly
specified.
NOTE:
The removal of operation type checking in the MERGE_LAST_WITH_ANY cases
is not a problem because all the Operation*::merge_operations() methods
ensure the operation types match as part of the merge attempt.
Bug 755214 - Refactor operation merging
Rename Win_GParted::Merge_Operations() to merge_two_operations(). To
reflect what it does and in preparation for further refactoring of the
code.
Be more strict on the validation of the first and second indexes. The
first operation must also be before the second operation in the
operation[] vector. (It is actually a programming bug if first and
second fail validation. However so far g_assert() is only being used to
validate pointers, which if wrong would likely cause the program to
eventually crash when dereferenced later. In this case a bug would
merely cause the incorrectly specified pair of operations to not be
merged).
Move validate_display_partition_ptr() declaration in the header file to
be in the same ordering as it's definition in the source file.
Bug 755214 - Refactor operation merging
Win_GParted::Merge_Operations() method was modifying the internals of
Operation* objects; in particular the partition_new member variable.
This is breaking data hiding and encapsulation tenant of object oriented
programming.
Implement exactly the same operation merge semantics, but hide the
manipulation of the internals of the Operation* objects within the
Operation* classes themselves.

Move vector of partition objects to a Win_GParted class member (#750168)
Perform a copy, reformat source and paste sequence in GParted. When the
source is a primary partition everything works as expected, with the
newly pasted partition reflecting the reformatted source. However when
the source is a logical partition GParted thinks it is pasting the
original source, rather than the reformatted source. The same is also
true for other file system manipulation operations: resize, file system
label and new UUID. It is just that reformatting the source to a
different file system type is the most obvious in the UI and causes the
most significantly wrong actions to be performed.
For example start with an ext4 logical partition, select it for copy,
format it to xfs and paste into a new partition. GParted thinks the
second operation will create a copy of an ext4 file system instead of
the xfs file system. When applied the operation details are:
Format /dev/sdd5 as xfs
+ calibrate /dev/sdd5
+ clear old file system signatures in /dev/sdd5
+ set partition type on /dev/sdd5

GParted formatted sdd5 to xfs, but then the copy step ran e2fsck and
managed to resurrect the ext4 file system and then performed a block
copy of it to partition sdd6. The copy step should have ran xfs_repair
and used xfsdump | xfsrestore to copy the xfs file system. Afterwards
sdd5 contains both xfs and ext4 signatures.

This has been broken at least as far back as GParted 0.1.0.
Fix by simply refreshing the copy source partition object when it is a
logical partition too, as well as when it is a primary partition.
Bug 754827 - Copy, reformat source and paste a logical partition thinks
it's pasting the original file system
