An action file is always needed with polkit to describe the privileged
actions that are available to the subject (client program). For GParted
the only available action is to run the gparted shell script as root.
Note that the polkit action file will be installed into location
$(prefix)/share/polkit-1/actions. This is required by the GNU Coding
Standards [1] and to prevent 'make distcheck' from failing [2]. However
polkit only uses /usr/share/polkit-1/actions for it's action files [3].
This dilemma was discussed in this Bugzilla bug 776437 and on the
general Automake discussion email list [4]. The solution is to simply
document in the README file that a manual additional installation step
may be required.
The action file is marked as translatable with the underscore (_) of the
_description and _message tags identifying the string to be translated.
Use of INTLTOOL_POLICY_RULE in Makefile.am to merge translations into
the polkit action file necessitates increasing the minimum version of
intltool to 0.36.0 where it was first introduced in intltool.m4. This
will prevent GParted building on RedHat/CentOS 5 which only has intltool
0.35.0. But that doesn't matter because RedHat/CentOS 5 reached end of
life on 31st March 2017.

Files were named Block_Copy and the class was named block_copy. Change
to the primary naming convention of CamelCase class name and matching
file names.
Also make CopyBlocks::copy_block() a private method as it is only used

Bug 775932 - Refactor mostly applying of operations
The GParted_Core::mount_info and GParted_Core::fstab_info maps and the
methods that manipulate them are self-contained. Therefore move them to
a separate Mount_Info module and reduce the size of the monster
GParted_Core slightly.
In some cases creating an LVM2 Physical Volume on top of a DMRaid array
reports no usage information and this partition warning:
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for lvm2
pv file system support: lvm2.
For example on Ubuntu 14.04 LTS (with GParted built with
--enable-libparted-dmraid) create an LVM2 PV in a DMRaid array
partition. GParted uses this command:
# lvm pvcreate -M 2 /dev/mapper/isw_bacdehijbd_MyArray0p2
But LVM reports the PV having a different name:
# lvm pvs
PV VG Fmt Attr PSize PFree
/dev/disk/by-id/dm-name-isw_bacdehijbd_MyArray0p2 lvm2 a-- 1.00g 1.00g
This alternate name is loaded into the LVM2_PV_Info module cache. Hence
when GParted queries partition /dev/mapper/isw_bacdehijbd_MyArray0p2 it
has no PV information against that name and reports unknown usage.
However they are actually the same block special device; major 252,
minor 2:
# ls -l /dev/mapper/isw_bacdehijbd_MyArray0p2
brw-rw---- 1 root disk 252, 2 Jul 2 11:09 /dev/mapper/isw_bacdehijbd_MyArray0p2
# ls -l /dev/disk/by-id/dm-name-isw_bacdehijbd_MyArray0p2
lrwxrwxrwx 1 root root 10 Jul 2 11:09 /dev/disk/by-id/dm-name-isw_bacdehijbd_MyArray0p2 -> ../../dm-2
# ls -l /dev/dm-2
brw-rw---- 1 root disk 252, 2 Jul 2 11:09 /dev/dm-2
To determine if two names refer to the same block special device their
major, minor numbers need to be compared, instead of string comparing
their names.
Implement class BlockSpecial which encapsulates the name and major,
minor numbers for a block special device. Also performs comparison as
needed. See bug 767842 comments 4 and 5 for further investigation and
decision for choosing to implement a class.
Replace name strings in the LVM2_PV_Info module with BlockSpecial
objects performing correct block special device comparison.

device names
Write a generic progress bar class. Has the following features:
* Has separate progress and target numbers, rather than a single
completion fraction, to enable the the next feature.
* Optionally generates text reporting the amount of data copied using
the progress and target numbers like this:
"1.00 MiB of 16.00 MiB copied"
* After running for 5 seconds, also add estimated remaining time.
(Waits to allow the data copying rate to settle down a little before
estimating the remaining time). Looks like this:
"1.00 MiB of 16.00 MiB copied (00:01:59) remaining)"
The ProgressBar class is not driving the visual progress bar yet. It
has just been added into the internal block copy algorithm and generates
debug messages showing the progress bar is operating correctly.
Debugging looks like this:

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.

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.

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.

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.

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
