Curtis Gedak de5019caf7 Fix missing "old end" value in detail log of en_CA translation (#756878)
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:

Mike Fleetwood 2c4df87a2c Return reference from Get_New_Partition() (#757671)
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( ... );

Mike Fleetwood c86b258475 Create unallocated space within new extended partition after aligning boundaries (#757671)
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.

Mike Fleetwood 6e97a63f49 Always use blkid file system detection before libparted (#757781)
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

Mike Fleetwood 32b5106aa1 Add clearing of ZFS labels
ZFS labels were not cleared by GParted when clearing old file system
signatures.

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.

Mike Fleetwood eec78cd2b2 Stop over rounding up of signature zeroing lengths (#756829)
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.

Mike Fleetwood 743968ef68 Add clearing of SWRaid metadata 0.90 and 1.0 super blocks (#756829)
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 --create /dev/md1 --level=linear --raid-devices=1 --force --metadata=1.0 /dev/sdb1
    # mdadm --stop /dev/md1
    [In GParted format to cleared /dev/sdb1]
    # blkid /dev/sdb1
    /dev/sdb1: UUID="8ac947a7-063f-2266-5f2a-e5d178198139" UUID_SUB="49bd51d4-4c54-fb16-a45e-bd795f783f59" LABEL="rockover:1" TYPE="linux_raid_member"

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.

    # mkdosfs -F 32 /dev/sdb1
    # blkid /dev/sdb1
    /dev/sdb1: UUID="8ac947a7-063f-2266-5f2a-e5d178198139" UUID_SUB="49bd51d4-4c54-fb16-a45e-bd795f783f59" LABEL="rockover:1" TYPE="linux_raid_member"

(Deliberately avoided btrfs, ext2/3/4 and xfs as recent versions of
their mkfs tools clear other signatures first for the same reason).

Mike Fleetwood a86f28bc32 Handle unusual case of missing mdadm but SWRaid arrays active (#756829)
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.

Mike Fleetwood f6c2f00df7 Populate member mount point with SWRaid array device (#756829)
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.

Mike Fleetwood 7255c8af40 Use UUID and label of SWRaid arrays too (#756829)
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
    ARRAY /dev/md/1  level=raid1 metadata=1.0 num-devices=2 UUID=15224a42:c25bbcd9:15db6000:4e5fe53a name=chimney:1
       devices=/dev/sda1,/dev/sdb1
    ...
    ARRAY /dev/md127 level=raid1 num-devices=2 UUID=8dc7483c:d74ee0a8:b6a8dc3c:a57e43f8
       devices=/dev/sdb6,/dev/sda6
    ...

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.

Add active attribute to the cache of SWRaid members.  Move parsing of

Mike Fleetwood 5f02bcf463 Detect Linux SWRaid members by querying mdadm (#756829)
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

                         UUID:  15224a42-c25b-bcd9-15db-60004e5fe53a

    # parted /dev/sda print

     1      1049kB  538MB   537MB   primary   ext4         boot, raid
    ...

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.

Mike Fleetwood 9d6ebb3dab Check usability of named device following a non-existent / invalid one (#756434)
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

Mike Fleetwood bbf1a19cec Remove non-existent or invalid devices from those named (#756434)
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.

Mike Fleetwood 362b2db331 Check disks named on the command line are safe to use too (#755495)
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

    # gparted
    ======================
    libparted : 2.1
    ======================
    Device /dev/sdd has a logical sector size of 4096.  Not all parts of
    GNU Parted support this at the moment, and the working code is
    HIGHLY EXPERIMENTAL.

    Ignoring device /dev/sdd with logical sector size of 4096 bytes.
    GParted requires libparted version 2.2 or higher to support devices
    with sector sizes larger than 512 bytes.

However when the device is named it is not ignored and can be edited:

    # gparted /dev/sdd
    ======================
    libparted : 2.1
    ======================
    Device /dev/sdd has a logical sector size of 4096.  Not all parts of
    GNU Parted support this at the moment, and the working code is
    HIGHLY EXPERIMENTAL.

    /dev/sdd: unrecognised disk label

Apply the same validity checks to disk devices named on the command line
as to probed ones.

Mike Fleetwood d6d7cb2bbf Enable C++11 compilation when using glibmm 2.45.40 and later (#756035)
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.
      (Murray Cumming, Kjell Ahlstedt)

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
    C++11 support.  For instance, using CXXFLAGS="--std=c++11", though
    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
the latest glibmm library fails with errors such as these:

    /usr/include/glibmm-2.4/glibmm/ustring.h:267:14: error: expected ';' at end of member declaration

2015-10-04 10:13:20 -06:00
Albert Young 584137b32b Remove prohibited characters from FAT16/32 labels (#755608)
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.

Mike Fleetwood 0e8f24b92b Fix visually re-applying copy new operation in create-copy-grow-first sequence (#755214)
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.
