Bug 467925 - gparted: add progress bar during operation
The Canadian English translation po file incorrectly changed the
following string with a parameter from %1 to %2:
msgid "old end: %1"
msgstr "old end: %2"
The error resulted in a missing "old end:" numerical value in the
gparted details log.
This error was introduced back in 2011-09-06 with the following
commit:

Return newly constructed partition object by reference rather than by
copy from the Copy, Resize/Move and New dialog classes. This is another
case of stopping copying partition objects in preparation for using
polymorphic Partition objects. In C++ polymorphism has to use pass by
pointer and reference and not pass by value, copying, to avoid object
slicing.
The returned reference to the partition is only valid until the dialog
object containing the new_partition member is destroyed. This is okay
because in all three cases the returned referenced partition is copied
into a context with new lifetime expectations before the dialog object
is destroyed.
Case 1: GParted_Core::activate_paste()
Referenced new_partition is copied in the OperationCopy constructor
before the dialog object goes out of scope.
Operation * operation = new OperationCopy( ...,
dialog.Get_New_Partition( ... ),
... );
Case 2: GParted_Core::activate_new()
Referenced new_partition is copied in the OperationCreate
constructor before the dialog object goes out of scope.
Operation * operation = new OperationCreate( ...,
dialog.Get_New_Partition( ... ) );
Case 3: GParted_Core::activate_resize()
Temporary partition object is copied from the referenced
new_partition before the dialog object goes out of scope.
Partition part_temp = dialog.Get_New_Partition( ... );
Bug 757671 - Rework Dialog_Partition_New::Get_New_Partition() a bit
Replace the use of local Partition variable with class member in
preparation for Dialog_Partition_New::Get_New_Partition() being changed
to return the new partition object by reference instead of by value.
part_temp -> new_partition
Bug 757671 - Rework Dialog_Partition_New::Get_New_Partition() a bit
When creating a new extended partition, the unallocated space within it
was being created before adjusting the partition boundaries for
alignment reasons. This must be wrong. Move creation of the
unallocated space to after adjusting the partition boundaries for
alignment reasons. First introduced by this commit:
a30f991ca5
Fix size reduced by 1 MiB when created after cylinder aligned partition
Also added a big FIXME comment explaining how further adjustments are
still made by snap_to_alignment() to the partition boundaries including
a test case where this too late adjustment causes overlapping boundaries
and apply to fail.
Bug 757671 - Rework Dialog_Partition_New::Get_New_Partition() a bit
This is just to make the parameter name in the Dialog_Partition_New
constructor and set_data() method match the name of the equivalent
parameter in the Dialog_Partition_Copy and Dialog_Partition_Resize_Move
classes. (All three classes inherit from Dialog_Base_Partition and have
similar interfaces).
Bug 757671 - Rework Dialog_Partition_New::Get_New_Partition() a bit
Blkid recognises many more file system types and RAID member signatures
than libparted. GParted already uses blkid detection instead of or
before libparted for whole disk devices [1] and for ext4 detection [2]
(only required with libparted < 1.9.0). Also GParted could only use
blkid detection on non-512 byte sector devices [3] before libparted was
fixed in version 3.2 [4]. Blkid was documented as a mandatory
requirement from GParted 0.24.0 [5].
Util-linux package, of which blkid command is a part, is a core piece of
Linux software which is very actively maintained and used by lots of
other packages. Parted package is much less active and has added
detection of fewer file systems and doesn't recognise any RAID members.
In cases of multiple signatures within a partition blkid and libparted
can report different results leading to confusion and issues for
GParted. This was the primary reason for bug 688882 "Improve clearing
of file system signatures" and a number of other changes to GParted.
Also as the mount command links with libblkid it uses it's detection
when telling the kernel the type of a file system to be mounted.
There aren't any current issues with GParted's file system detection but
given the above argument, switch to using blkid before libparted for
file system detection. Only falling back to libparted when blkid
doesn't report a result, notably for extended partitions. Order of
information sources for detection is now:
1) mdadm (for SWRaid members)
2) blkid
3) libparted
4) GParted internal code

Update to also zero all 4 ZFS labels.
NOTE:
GParted now writes a little over 1 MiB when clearing old file system
signatures. As this is performed in the main thread the UI is not able
to respond during this action. Testing this on a range of USB flash
keys and hard drives found the slowest normal time to write this was
0.25 seconds, with an occasional outlier up to 2.8 seconds from a USB
flash key. This is considered acceptable.
Following the previous commit "Add erasing of SWRaid metadata 0.90 and
1.0 super blocks (#756829)" signature zeroing specified to write 4 KiB
of zeros at position end - 64 KiB, aligned to 64 KiB. Example operation
details from formatting a 1 GiB partition to cleared:
Format /dev/sdb8 as cleared
+ calibrate /dev/sdb8
+ clear old file system signatures in /dev/sdb8
+ write 68.00 KiB of zeros as byte offset 0
+ wite 4.00 KiB of zeros at byte offset 67108864
+ wite 64.00 KiB of zeros at byte offset 1073676288
+ write 8.00 KiB of zeros at byte offset 1073733632
+ flush operating system cache of /dev/sdb
However it actually wrote 64 KiB. This is because the rounding /
alignment was also applied to the zeroing length. Before this commit
rounding / alignment was always less than or equal to the length so this
wasn't seen before. Instead just apply device sector size rounding up
to the length.
Bug 756829 - SWRaid member detection enhancements
The super blocks for Linux Software RAID arrays using metadata types
0.90 and 1.0 are stored at the end of the partition and not currently
cleared by GParted.
Create a SWRaid array, stop it and format it to cleared using GParted.
The signature remains.

# mdadm --stop /dev/md1

As fixed in other cases before [1][2] it is necessary to clear all
signatures before formatting as a new file system to prevent recognition
issues. For example now format the partition as a FAT32 file system.
Now there are two signatures and libparted reports one type and blkid
reports another.

Bug 756829 - SWRaid member detection enhancements
If the installation is unusual / broken such that the mdadm command is
not found but there are active SWRaid arrays, provide a fallback with
some of the information. In this case populate the cache with details
only available from /proc/mdstat. Information will be limited to active
arrays only and their members. No UUIDs or labels. There will be no
information about inactive arrays and GParted will use it's normal
libparted and blkid identification for those devices and partitions.
As mdadm has gained the capability to manage Fake/BIOS RAID arrays they
also appear in /proc/mdstat when mdadm is used to start them. Enhance
the parser of /proc/mdstat to only extract information for SWRaid arrays
with recognised metadata versions.
Bug 756829 - SWRaid member detection enhancements
Automatically load the cache of SWRaid information for the first time if
any of the querying methods are called before the first explicit
load_cache() call. Means we can't accidentally use the class and
incorrectly find no SWRaid members when they do exist.
Bug 756829 - SWRaid member detection enhancements
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"

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

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

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,

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

the latest glibmm library fails with errors such as these:

Bug 756035 - GParted does not compile with newer gtkmm libraries in
Fedora 23
Older distributions don't include Autoconf Archive at all and newer
distributions don't always include it. Therefore we have to have a
local copy of the AX_CXX_COMPILE_STDCXX_11 macro with GParted.

Add recognition for work done by Albert Young to prevent a hang in
GParted labeling FAT16/32 if label contained illegal characters.
Bug 755608 - Labeling fat16/fat32 partitions hangs if certain
characters included in label
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
Long file name "MYLABEL/ " contains illegal character(s).
a)utorename A)utorename-all r)ename R)ename-all
s)kip S)kip-all q)uit (aArRsSq):
Remove prohibited characters from FAT16/32 file systems labels when
creating and labelling them. Also upper case the label to meet label
requirements [1][2]. This silently corrects the label and the actual
label applied will be displayed when GParted refreshes after applying
the operation.

These member variables store no Operation class information and were
being used as local variables. Replace with local variables.
Also indent a code block within an if clause so that the compiler can
confirm that the new local variable isn't used uninitialised. Prevents
this compiler warning:
OperationResizeMove.cc: In member function 'void GParted::OperationResizeMove::apply_normal_to_visual(std::vector<GParted::Partition, std::allocator<GParted::Partition> >&)':
OperationResizeMove.cc:125: warning: 'index' may be used uninitialized in this function
Bug 755214 - Refactor operation merging
Since this commit earlier in the patchset the second optional parameter
of method Win_GParted::Add_Operation() is no longer used. Remove it.
Replace open coded merge of resize/move into create operation
(#755214)
Bug 755214 - Refactor operation merging
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.
