Absolute minimum implementation of a PartitionLUKS class which can be
constructed, polymorphically copied and destroyed. Contains an
"encrypted" member of type Partition to represent the encrypted file
system within the LUKS format.
Create PartitionLUKS objects instead of base Partition objects when a
LUKS formatted partition is found. Only the base Partition object
member values have been populated, and the "encrypted" member remains
blank at this point.
Bug 760080 - Implement read-only LUKS support
Provide a minimal implementation of a luks file system class which only
does busy detection.
NOTE:
For now, read-only LUKS support, a LUKS partition will be busy when a
dm-crypt mapping exists. Later when read-write LUKS support is added
GParted will need to look at the busy status of the encrypted file
system within the open LUKS partition and map LUKS partition busy status
to encryption being open or closed.

Load basic details of active Device-mapper encryption mappings from the
kernel. Use dmsetup active targets.
# cryptsetup luksFormat /dev/sdb5
# cryptsetup luksFormat /dev/sdb6
# cryptsetup luksOpen /dev/sdb6 sdb6_crypt
# ls -l /dev/mapper/sdb6_crypt /dev/dm-0
lrwxrwxrwx. 1 root root 7 Nov 15 09:03 /dev/mapper/sdb6_crypt -> ../dm-0
brw-rw----. 1 root disk 253, 0 Nov 15 09:03 /dev/dm-0
# ls -l /dev/sdb6
brw-rw----. 1 root disk 8, 22 Nov 15 09:02 /dev/sdb6
# dmsetup table --target crypt
sdb6_crypt: 0 1044480 crypt aes-cbc-essiv:sha256 0000000000000000000000000000000000000000000000000000000000000000 0 8:22 4096
So far just load the mapping name and underlying block device reference
(path or major, minor pair).
Note that all supported kernels appear to report the underlying block
device as major, minor pair in the dmsetup output. Underlying block
device paths are added to the cache when found during a search to avoid
stat(2) call on subsequent searches for the same path.
Prints debugging to show results, like this:

Bug 760080 - Implement read-only LUKS support
The PartitionVector class is now internally using pointers to Partition
objects and taking on management of their lifetimes. It therefore has
to implement the Big 3: destructor, copy constructor and copy assignment
operator [1][2]. This is because the implicitly-defined copy
constructor and assignment operator perform memberwise "shallow copying"
and the destructor does nothing. This not correct for classes which
contain non-class types such as raw pointers.
The semantics of the interface still copies each Partition object into
the PartitionVector when they are added with push_back() and insert().
Note that a PartitionVector object is explicitly copy assigned in
Win_GParted::Refresh_Visual(). They are also implicitly copied when
(1) the implementing vector is resized larger to allow it to hold more
pointers to Partition objects than it previously had capacity for; and
(2) a Partition object is copied including the logicals PartitionVector
member.

Bug 759726 - Implement Partition object polymorphism
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
Embedded devices (Android) use GPT partition names to identify
partitions, instead of file system labels. Add support for viewing and
changing them.
As partition names are used to provide unique identification they are
never copied when copying the contents of one partition to another.
Note that GNU/Linux uses file system labels, UUIDs or device names for
identification during the boot process and afterwards so while partition
names can be used, they are optional and purely for user information.
Bug 741424 - Add support for GPT partition names
As part of bug 700228, the fat16 and fat32 code was combined. As a
result, the fat32.cc file no longer exists and hence is not available
for translation.
Only supports detection and creation of f2fs file systems. Requires
f2fs-tools and a blkid with f2fs support, util-linux > 2.22.2.
f2fs-tools v1.1.0 only supports file system creation.
Currently requires util-linux directly from the git repository as f2fs
support was only committed on 5 Feb 2013 and it has not yet been
released.
Closes Bug #695396 - Please apply f2fs patch
Cache results from querying all LVM2 PVs in one go to minimise the
number of times lvm commands are executed. Take inspiration from
caching performed by FS_Info and Proc_Partitions_Info.
Bug #160787 - lvm support
Add minimal support for just reporting the space usage of LVM2 PVs.
Accept libparted / blkid detection of LVM2 PVs first, falling back on
GParted's specific detection code otherwise. Maintain LVM not supported
warning message.
Bug #160787 - lvm support
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.
Update the help manual to include this new functionality. Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.
This patch does not include setting the UUID on an NTFS file system.
Bug #667278 - Add support for setting UUID
Bug #608308 - fix documentation - Copying and Pasting a Partition
- Removed gparted-disable-automount.fdi handling.
- Renamed gparted binary to gpartedbin to permit a calling script to be named gparted.
- Added new calling script gparted.in to permit using hal-lock to acuiqre device locks to prevent automounting while executing gpartedbin.
- Renamed gparted.desktop.in to gparted.desktop.in.in to permit parsing installdir.

include/Makefile.am,

src/Win_GParted.cc: renamed 'Filesystems' to 'Features' in the
featuredialog to better reflect the actual functionality
* include/Dialog_Filesystems.h,
src/Dialog_Filesystems.cc: removed
* replaced the inline Utils functions with static functions.
This shaves a few kbytes (24 in fact) off the binary and is a bit
cleaner code-wise (imho).
* Harddisks without disklabel are now properly initizalized and shown in the menu. When one tries to create a new partition on
such a disk a dialog pops up with some blabla about disklabels and offers to create a disklabel. sweet :P (special thanks to mantiena-baltix
for bringing this issue to my attention)
* fixed minor annoyance with refreshing detailed deviceinfo after a 'deep refresh'

* po/.cvsignore: Added an entry.
* po/POTFILES.in: Added comment.
